Description

The present invention relates to a game server that manages the operation of a virtual user existing in a virtual space by operation data from each terminal connected via a communication network, a game control method that controls the progress of a game provided by the game server, it relates to the game program and a game program recording medium body.

  In recent years, with the spread of highly functional mobile terminals typified by smartphones, social network games (hereinafter referred to as social games) are becoming popular as games provided using social networking services (SNS). In social games, a real user who operates a terminal operates a virtual user that exists in a virtual space constructed by a game server via a communication network, so that other virtual users that exist in the same virtual space This game is played online while communicating.

  As one aspect of the social game, based on the action and story of a virtual user, for example, a scenario is formed by combining a plurality of game parts such as a quest part, a battle part, a reinforcement part, and a gacha part, Some are configured (see, for example, Patent Document 1).

  Such a card game composed of a plurality of game parts is executed by executing each part including a gacha part, whereby a virtual card (hereinafter simply referred to as a card) to which various types of characters such as several hundred types are attached. ) And a set of cards (hereinafter referred to as a card deck) consisting of a predetermined number of cards is created from the cards acquired by the virtual user. More specifically, while leveling up the cards on the card deck and selecting attributes, you can play cards against enemies that appear in the virtual space, or trade cards with other virtual users. Then, strengthen and collect cards. In card-to-card battles, the attack power and defensive power of each card making up the card deck, and skills that achieve a certain level of effectiveness through a combination of predetermined cards (corresponding to “games” in card games and mahjong), etc. The damage to the enemy and the victory or defeat are decided.

  In the gacha part which is one of the game parts, a card is acquired by performing so-called “gacha”. This “gacha” is derived from “Gachagacha” (registered trademark), which shows a state in which a capsule toy, which is a toy containing a capsule, comes out by inserting coins into a vending machine. Cards acquired by gacha are generally associated with each virtual item, identification information for identifying the card in the virtual space, a name that is the name of the character attached to the card, a rarity indicating “rareness”, The database is configured with information such as attributes to be added. The gacha part randomly draws from such a database according to the appearance rate and gives the picked up card to the virtual user (see, for example, Patent Document 2).

JP 2012-24248 A JP 2008-253521 A

  Conventionally, a real user can acquire a card by obtaining the right to execute gacha by charging, that is, a lottery right. The amount of billing for obtaining the lottery right was constant. Therefore, it was insufficient to give real users a willingness to obtain a lottery right continuously.

This invention is made in view of the subject mentioned above, and raises the willingness to acquire a virtual item of a real user by hitting the measure devised in the method of giving a virtual item to a virtual user at random. and to provide a game control method, a game program and a game program recording medium body game server capable to control the progress of the game provided in the game server.

  In order to solve the conventional problems described above, the present invention has the following means.

(1) A game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right; a purchase acceptance unit that accepts the purchase of the item acquisition right at a set price; and a virtual space when the purchase of the item acquisition right is accepted An item setting unit that randomly selects one virtual item from among the virtual items in the list, sets the selected virtual item as an owned item of the virtual user, and accepts purchase of the item acquisition right in a predetermined unit period It includes a condition setting unit that sets a count condition, wherein the condition setting unit, based on the own item information of the virtual user The more owned number of virtual items attached with a predetermined rank or more rarity level, and set to be a lot predetermined number of times receiving a predetermined unit period, the pricing section, the virtual user by the item acquired rights Based on the purchase history information, the price of the item acquisition right is set, and when the purchase reception unit receives the purchase of the item acquisition right more than the predetermined number of times in the predetermined unit period, The price is changed to a price lower than a predetermined price .

  In the above aspect, the purchase price of the item acquisition right varies depending on the purchase history of the item acquisition right by the virtual user. When the real user who operates the virtual user pays an amount corresponding to the purchase price set by the price setting unit, the virtual user can acquire the virtual item. The virtual item is not particularly limited as long as it is an item that can be used in each game, and examples thereof include a card on which a character is displayed. The item acquisition right can be purchased in, for example, real currency, currency common to a plurality of games purchased in real currency, in-game currency, or the like. In this aspect, depending on the purchase history of the item acquisition right, the actual user can pay less to purchase the item acquisition right, and can acquire the virtual item with a small amount. For example, the purchase price of the item acquisition right decreases as the actual user purchases more item acquisition right in the past. As a result, it is possible to stimulate the real user who wants to purchase the item acquisition right with a smaller amount of money and to guide the purchase of the item acquisition right.

Further, in this aspect, when the actual user purchases the item acquisition right at least a predetermined number of times in a predetermined unit period, the purchase price of the item acquisition right decreases. Thereby, in order to reduce the purchase price of the item acquisition right, the real user can be guided to purchase the item acquisition right a predetermined number of times in a predetermined unit period. If the actual user purchases the item acquisition right a predetermined number of times during a predetermined unit period and then purchases the item acquisition right a predetermined number of times during the next predetermined unit period, the purchase price of the item acquisition right continuously decreases. Thereby, the real user can be guided to purchase the item acquisition right continuously.

Furthermore, in this aspect, the conditions under which the purchase price of the item acquisition right decreases depending on the items owned by the virtual user. Usually, the number of possessed virtual items with a high degree of rarity increases in proportion to the time that a real user plays a game. That is, a virtual user with a large number of virtual items owned by a high degree of rarity is an advanced user, and a virtual user with a small number of virtual items owned by a high degree of rarity is a beginner user. By setting price reduction conditions easily so that the prescribed number of times per unit period is reduced for the novice user, the novice user can be guided to purchase of the item acquisition right. By making the novice user realize the pleasure of acquiring a virtual item by purchasing the item acquisition right, it is possible to guide the user to purchase the item acquisition right continuously.

(2) The game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right; a purchase acceptance unit that accepts the purchase of the item acquisition right at a set price; and a virtual space when the purchase of the item acquisition right is accepted An item setting unit that randomly selects one virtual item from among the virtual items in the list, sets the selected virtual item as an item owned by the virtual user, and the purchase amount of the item acquisition right by the virtual user during a predetermined period Alternatively, the purchase-related calculation unit that calculates the number of purchases and the item setting unit in the predetermined period include a predetermined run. An item-related calculation unit that calculates the number of times of selection of the virtual item with the above rarity level, and the price setting unit is based on purchase history information of the item acquisition right by the virtual user. A price of the acquisition right is set, and the price of the item acquisition right is changed to a price lower than a predetermined price when the purchase amount or the number of selections with respect to the number of purchases is a predetermined threshold value or less. .

In the above aspect, the purchase price of the item acquisition right decreases when the number of acquisitions of the virtual item with a high degree of rarity is equal to or less than a predetermined threshold with respect to the purchase amount or the number of purchases of the item acquisition right in the predetermined period. . A virtual item with a high degree of rarity is highly demanded by real users. Even if the item acquisition right is continuously purchased, if a virtual item with a high degree of rarity cannot be acquired, the willingness to purchase the item acquisition right by the real user may be reduced. Therefore, by reducing the purchase price of item acquisition rights for virtual users who have not purchased virtual items with a high degree of rarity even though they have purchased many item acquisition rights, The willingness to continue purchasing can be maintained.

(3) The game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right; a purchase acceptance unit that accepts the purchase of the item acquisition right at a set price; and a virtual space when the purchase of the item acquisition right is accepted A virtual item is selected at random from among the virtual items, and an item setting unit that sets the selected virtual item as an item owned by the virtual user, and a predetermined period based on the battle history information of the virtual user Winning percentage calculation unit for calculating the winning percentage of the virtual user in the item, and item acquisition by the virtual user in the predetermined period A purchase-related calculation unit that calculates the purchase price or the number of purchases of the item, and the price setting unit sets the price of the item acquisition right based on purchase history information of the item acquisition right by the virtual user, When the winning rate is equal to or lower than a predetermined threshold and the purchase amount or the number of purchases is equal to or higher than a predetermined threshold, the price of the item acquisition right is changed to a price lower than a predetermined price. .

In the above aspect, the purchase price of the item acquisition right decreases when the winning rate in the predetermined period is equal to or less than a predetermined threshold and the purchase amount or the number of purchases of the item acquisition right is equal to or higher than the predetermined threshold. In order to win in-game battles, you need to own more virtual items with a high degree of rarity. Real users purchase item acquisition rights in the hope that they can acquire virtual items with a high degree of rarity. However, it is highly possible that a virtual item with a high degree of rarity has not been acquired because it is not possible to win a battle despite purchasing many item acquisition rights. If a virtual item with a high degree of rarity cannot be acquired, the willingness to purchase an item acquisition right by a real user may be reduced. Therefore, by reducing the purchase price of the item acquisition right for a virtual user with a low win rate and a large purchase amount or number of purchases, the willingness to continue purchasing the item acquisition right can be maintained.

(4) The game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right; a purchase acceptance unit that accepts the purchase of the item acquisition right at a set price; and a virtual space when the purchase of the item acquisition right is accepted An item setting unit that randomly selects one virtual item from among the virtual items in the list, sets the selected virtual item as an item owned by the virtual user, and item acquisition rights by the virtual user for each predetermined period A calculation unit for each period for calculating the purchase price or the number of purchases, and the price setting unit is an item by the virtual user The price of the item acquisition right is set based on the purchase history information of the right of acquisition, and in the two predetermined periods having the same length, the purchase amount or the number of purchases in the first predetermined period is more than the first When the purchase amount or the number of purchases in the second predetermined period after the predetermined period is large, the price of the item acquisition right is changed to a price lower than the predetermined price .

In the above aspect, when the purchase amount or the number of purchases in the second predetermined period is larger than the purchase amount or the number of purchases in the first predetermined period, the purchase price of the item acquisition right is lowered. Usually, when a virtual user acquires a virtual item, the in-game level of the virtual user increases. By gradually increasing the purchase amount or the number of purchases every time the predetermined period elapses, the item acquisition right can be provided at a purchase price corresponding to the in-game level of the virtual user.

(5) A game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right; a purchase acceptance unit that accepts the purchase of the item acquisition right at a set price; and a virtual space when the purchase of the item acquisition right is accepted Based on the operation data from the terminal, an item setting unit that selects one virtual item at random from among the virtual items in the inside, and sets the selected virtual item as the possessed item of the virtual user, the virtual user A deck construction unit that constructs a predetermined number of virtual items from among the possessed items as a deck, and the price setting unit The price of the item acquisition right is set based on the purchase history information of the item acquisition right by the virtual user, and the virtual item newly set as the item owned by the virtual user by the item setting unit is constructed as the deck The price setting unit changes the price of the item acquisition right to a price lower than a predetermined price when the virtual item is not a virtual item related to the virtual item being set .

In the above aspect, when the virtual item newly acquired by the virtual user by purchasing the item acquisition right is not a virtual item related to the virtual item constructed as a deck, the purchase price of the item acquisition right decreases. The deck is constructed by a real user freely selecting a predetermined number of virtual items from virtual items owned by the virtual user. Usually, in an in-game battle, the winning or losing is determined by the total value of the attack power exhibited by the virtual items constructed as a deck. Therefore, the real user desires to acquire a virtual item that can increase the attack power exhibited by the virtual item constructed as a deck. For example, if the attack power is increased by combining virtual items of the same type, the real user has a high desire to acquire a virtual item of the same type as the virtual item constructed as a deck. In addition, if the virtual item is classified into a plurality of attributes and the attack power is increased by combining virtual items with the same attribute, the real user selects the same type of virtual item as the virtual item constructed as a deck. High desire to get. A real user is considered to purchase an item acquisition right in the hope that a virtual item related to a virtual item constructed as a deck can be acquired. Therefore, if the virtual item newly acquired by purchasing the item acquisition right is not a virtual item related to the virtual item constructed as a deck, the item acquisition right is continued by reducing the purchase price of the item acquisition right. Increase your willingness to buy.

(6) The game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right for each team, a purchase acceptance unit that accepts purchase of the item acquisition right at a set price, and a purchase of the item acquisition right, An item setting unit that randomly selects one virtual item from virtual items in the virtual space, sets the selected virtual item as an item owned by the virtual user, and purchases of the item acquisition right in a predetermined unit. A condition setting unit that sets a number of times conditions received in a period, and the condition setting unit is a virtual user belonging to the team Based on the number, the larger the number, the larger the predetermined number of times received in the predetermined unit period is set or the initial price is set to be higher, the price setting unit is a plurality of belonging to the team When the price of the item acquisition right is set based on the purchase history information of the item acquisition right by the virtual user, and the purchase receiving unit receives the purchase of the item acquisition right more than the predetermined number of times in the predetermined unit period Further, the price of the item acquisition right is changed to a price lower than a predetermined price .

In the above aspect, when the virtual user belongs to the team, the purchase price of the item acquisition right varies depending on the purchase history of the item acquisition right by a plurality of virtual users belonging to the team. Therefore, depending on the actual user, even if the actual user has not purchased the item acquisition right, if the other real user has purchased a large amount of item acquisition right, the amount to be paid to purchase the item acquisition right is small. In some cases, virtual items can be acquired with a small amount of money. This gives not only real users who have purchased a lot of item acquisition rights in the past, but also real users who usually do not purchase much item acquisition rights, an opportunity to acquire virtual items with a small amount of money. You can guide them to purchase acquisition rights. In addition, for real users who have purchased many item acquisition rights in the past, they can realize that purchasing the item acquisition right will contribute to the team, You can be guided to purchase more.

Moreover, in this aspect, in order to reduce the purchase price of the item acquisition right, it is necessary to purchase more item acquisition rights in a predetermined unit period as the number of virtual users belonging to the team increases. Further, the larger the number of virtual users belonging to the team, the higher the initial price is set. If the number of virtual users belonging to the team is large, the number of purchases in the entire team is large, and the purchase price of the item acquisition right is likely to be reduced as compared with the case where the number of virtual users belonging to the team is small. Therefore, by setting conditions according to the number of virtual users belonging to the team, unfairness due to the difference in the number of virtual users belonging to the team can be eliminated.

(7) The game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right for each team, a purchase acceptance unit that accepts purchase of the item acquisition right at a set price, and a purchase of the item acquisition right, Each time a virtual item in the virtual space is selected at random from a virtual item, the selected virtual item is set as an item owned by the virtual user, and purchase of the item acquisition right is accepted An appearance rate setting unit that sets an appearance rate of the virtual item, and the price setting unit belongs to the team Based on the purchase history information of the item acquisition right by the number of virtual users, the price of the item acquisition right is set, and the appearance rate setting unit relates to the team to which the virtual user who has accepted the purchase of the item acquisition right belongs, The purchase frequency information of each virtual user belonging to the team is read, and the purchase frequency of the virtual user who accepted the purchase of the item acquisition right is relatively high in the team, and the degree of rarity of a predetermined rank or higher is given. The appearance rate of each virtual item is set so that the appearance rate of the virtual item is high, and the item setting unit randomly selects the virtual item based on the appearance rate set for each virtual item. And

In the above aspect, when the virtual user belongs to the team, the purchase price of the item acquisition right varies depending on the purchase history of the item acquisition right by a plurality of virtual users belonging to the team. Therefore, depending on the actual user, even if the actual user has not purchased the item acquisition right, if the other real user has purchased a large amount of item acquisition right, the amount to be paid to purchase the item acquisition right is small. In some cases, virtual items can be acquired with a small amount of money. This gives not only real users who have purchased a lot of item acquisition rights in the past, but also real users who usually do not purchase much item acquisition rights, an opportunity to acquire virtual items with a small amount of money. You can guide them to purchase acquisition rights. In addition, for real users who have purchased many item acquisition rights in the past, they can realize that purchasing the item acquisition right will contribute to the team, You can be guided to purchase more.

Moreover, in this aspect, the higher the team contribution to the purchase of the item acquisition right, the higher the probability that a virtual item with a high degree of rarity can be acquired. The team contribution is determined by, for example, the purchase frequency of an actual user in a period until the number of purchases reaches a predetermined number in a predetermined unit period. Specifically, if the predetermined number of times is 5, it is determined depending on how many times the actual user has purchased 5 times. The higher the purchase frequency, the higher the team contribution. In addition, a virtual item with a high degree of rarity is usually an item that can favorably advance a game, and a real user's desire for acquisition is high. Therefore, the real user can be guided to increase the team contribution in order to acquire a virtual item with a high degree of rarity.

In addition, as described above, in this aspect, not only a real user who purchases many item acquisition rights but also a real user who usually does not purchase much item acquisition rights acquires a virtual item with a small amount of money. Give an opportunity. Therefore, although the purchase price is common to the team, changing the appearance rate of virtual items with a high degree of rarity according to the degree of team contribution can give inequality to real users who have purchased many item acquisition rights. There is no.

(8) The game server of the present invention includes an operation data receiving unit that receives operation data for operating a virtual user formed in a virtual space from a terminal connected via a communication network, and a virtual in the virtual space. A price setting unit that sets a price required to purchase an item acquisition right; a purchase acceptance unit that accepts the purchase of the item acquisition right at a set price; and a virtual space when the purchase of the item acquisition right is accepted An item setting unit that randomly selects one virtual item from among the virtual items in the list, sets the selected virtual item as the owned item of the virtual user, and the item setting unit sets as the owned item of the virtual user Utilization rate when a virtual item with a degree of rarity above the specified rank is used for trading with other virtual users A trade-related calculation unit that calculates based on the trade history information of the virtual user, and prohibits changing the price of the item acquisition right to a price lower than a predetermined price when the usage rate exceeds a predetermined threshold A price change prohibiting unit configured to set the price of the item acquisition right based on purchase history information of the item acquisition right by the virtual user.

In the above aspect, it is prohibited to reduce the purchase price of the item acquisition right when the usage rate of using the virtual item with a high degree of scarcity acquired by purchasing the item acquisition right exceeds a predetermined threshold. Trade refers to exchanging a virtual item owned by a virtual user with a virtual item owned by another virtual user in the game. In the trade, generally, a virtual item arbitrarily selected from the virtual items owned by both virtual users is set as a trade target. By trading, one virtual user loses the virtual item owned by himself / herself set as a trade target, and acquires a virtual item owned by another virtual user set as a trade target. Since acquiring a virtual item with a high degree of rarity can advantageously advance the game, the real user does not let go of the virtual item with a high degree of rarity much. Therefore, it is highly likely that a real user who has just given up a rare virtual item acquired by purchasing an item acquisition right has purchased the item acquisition right for the purpose of real money trade (RMT). Therefore, when a virtual item with a high degree of rarity is used for trading with a high probability, the purchase of an item acquisition right for the purpose of RMT can be suppressed by prohibiting the purchase price from being lowered.

(9) In a preferred aspect of the game server according to the present invention, the price setting unit receives the item received in the predetermined unit period after changing the price of the item acquisition right to a price lower than a predetermined price. When the purchase of the right is less than the predetermined number of times, the price of the item acquisition right is changed to a price higher than the price changed to the lower price.

In the above aspect, when an actual user purchases an item acquisition right at least a predetermined number of times in a predetermined unit period, the purchase price of the item acquisition right decreases, but thereafter, the item acquisition right is not purchased at least a predetermined number of times during the predetermined unit period. As a result, the purchase price of the item acquisition right increases. As a result, it is possible to stimulate the real user who wants to purchase the item acquisition right with a smaller amount of money and to induce the purchase of the item acquisition right continuously.

(10) In a preferred aspect of the game server according to the present invention, an upper limit value setting unit that sets an upper limit value of the purchase amount for a predetermined period based on the age information of the real user stored in the storage unit, and the virtual user A purchase price determination unit that determines whether or not the purchase price of the virtual user exceeds an upper limit value of the set purchase price based on purchase history information of the item acquisition right by the price setting unit Is characterized in that when the upper limit value of the set purchase price is exceeded, the purchase price of the item acquisition right that is currently set is returned to the initial price .

  In the above aspect, when the purchase price of the virtual user in the predetermined period exceeds the upper limit value, the price setting unit returns the purchase price of the item acquisition right to the initial price. The upper limit value is set based on information registered in the terminal. An example of information registered in the terminal is age. By reducing the purchase price of the item acquisition right, the willingness of a real user to purchase the item acquisition right can be improved. However, if too many item acquisition rights are purchased in a predetermined period, it may be difficult for an actual user to purchase item acquisition rights continuously. Therefore, if the set upper limit is exceeded, the purchase price of the item acquisition right is returned to the initial price, thereby suppressing the purchase of the item acquisition right at once in a predetermined period, and continuously acquiring the item acquisition right to the actual user. Can be encouraged to purchase. By continuously purchasing item acquisition rights, the game can be played continuously.

The present invention as described above, in any of the embodiments, the invention of the game server, the game control method, a game program recorded medium body which stores a game program and a game program for controlling progress of a game provided in the game server it is also possible to capture as a.

ADVANTAGE OF THE INVENTION According to this invention, it provides with the game server which can raise the willingness to acquire a virtual item of a real user, and a game server by hitting the measure devised to the method of giving a virtual item to a virtual user at random game control method for controlling the progress of the game, it is possible to provide a game program recording medium body which stores a game program and a game program.

  A mode for carrying out the present invention (hereinafter referred to as the present embodiment) will be described with a specific example. The present embodiment relates to a game system that provides a game to a terminal connected to a game server via a communication network. Specifically, as shown in FIG. 1, a game system G according to the present embodiment includes a game server 1 that provides a game to a user, and a terminal 3a that is connected to the game server 1 via the Internet 2 that is a communication network. 3b, 3c,..., 3n (hereinafter collectively referred to as terminal 3).

  In the following, first, prior to the description of the embodiment, the definitions of terms used in the present embodiment are clarified, and the outline of the social game handled in the present embodiment is described. I will explain it.

(1) Definition of terms Definitions of terms used in the present embodiment are as follows.

  The “virtual space” indicates a virtual world formed during the game based on the content of the game, and indicates a space different from the physical space. The “virtual space” displayed on the display (display unit) of the terminal 3 is two-dimensional, but the ideal space formed by adding connections with other terminals 3 is not limited to the two-dimensional space.

  “Real user” refers to an entity operating a terminal, that is, a person hitting a person. On the other hand, a virtual entity impersonating the user or formed in accordance with the user's taste or preference in the virtual space by a button or touch operation on the terminal of the “real user” that is the entity is referred to as a “virtual user”. For this “virtual user”, the virtual entity cannot be visually recognized in the game, for example, as in the player of the traditional shogi game or mahjong game, but the piece or trap is impersonated as the “real user” in the virtual space. It also includes the case of operating with. The “virtual user” also includes a specific visible character that is displayed on the game in a role playing game or a battle game and causes movement or action. Furthermore, the “virtual user” includes a virtual entity displayed as an avatar in the SNS. As described above, the “virtual user” in the present embodiment is used as a term that broadly represents a virtual entity in the virtual space, and is a virtual entity that is embodied in the game or a virtual entity that functions as a shadow that is not embodied. It doesn't matter if it is.

(2) Outline of Social Game Next, an outline of the social game provided from the game server 1 to the terminal 3 connected via the Internet 2 will be described with reference to FIG.

  In general, a social game is a virtual item that is a virtual item to which, for example, hundreds of types of characters are added in a virtual space via a virtual user who performs an operation according to the operation of the terminal 3 by a real user. This is a game for creating an item list (hereinafter also referred to as a deck) of a predetermined number of cards from cards (hereinafter simply referred to as cards). More specifically, while leveling up the cards on the deck and selecting groups, you can play cards against enemies that appear in virtual space, or trade cards with other virtual users. , Strengthen and collect cards. In card-to-card battles, the attack power and defense power of each card that composes the deck, and skills that achieve a certain level of effectiveness through a combination of predetermined cards (equivalent to a “role” in a card game or mahjong), etc. , Damage to the enemy and victory or defeat are decided.

  In the social game, a plurality of game parts (hereinafter also simply referred to as “parts”) are organically combined to complete one story or character, and the whole game is formed as one game. For example, as shown in FIG. 2, the social game 20 includes a quest part 21, a battle part 22, a gacha part 23, and a strengthening part 24.

  The quest part 21 is a virtual card in which a virtual user searches the virtual space and fights enemies that appear during the search, as indicated by the word “quest” having significance such as “search, search, adventure”, or a new card. It is a part of a game that progresses by earning or improving the level of a virtual user. In the quest part 21, a predetermined quest point is given to the virtual user, and movement of the virtual user, acquisition of an item, improvement of a level, and the like are performed by consuming the quest point. Further, in the quest part 21, a battle point is played by using the card owned by the virtual user by consuming the battle points.

  The battle part 22 is a part where a virtual user owns a card in which a card is incorporated and battles against another virtual user as an enemy. Based on the attack power and defense power of each card constituting the deck described above. Victory or defeat is decided.

  The gacha part 23 is derived from “Gacha Gacha” (registered trademark), which represents a state in which a capsule toy that is a toy packaged in a capsule after coins are inserted into a vending machine. However, it is a part which acquires a card | curd at random using the authority for gacha virtually given instead of a coin. In the present embodiment, in the gacha part, the right to acquire a virtual item (item acquisition right) is referred to as “gacha right”. A purchase price is set for the gacha right, and the actual user can acquire the gacha right by paying an amount corresponding to the purchase price. The gacha right can be purchased in, for example, an actual currency, a currency common to a plurality of games purchased in the actual currency, an in-game currency, or the like. Then, the card can be acquired using the acquired gacha right.

  Strengthening part 24 synthesizes the cards owned by the virtual user and raises the level indicating the strength of the cards, thereby defending the attack power given to the enemy and the attack from the enemy when incorporated in the deck. It is a part that strengthens defense power.

  In the social game 20 composed of a plurality of parts as described above, each part alone is not independent of other game parts. As described above, the parts are related to each other and combined, It has significance as a whole. Therefore, in the social game 20, one game can be advanced as a whole when the virtual user effectively advances each game part.

(3) Basic Hardware Configuration (3-1) Terminal Configuration Based on the definition of the social game 20 as described above, a hardware configuration for realizing the game system G of the present embodiment will be described below.

  As illustrated in FIG. 1, the terminal 3 includes a portable wireless communication terminal including a wireless communication unit 31, a display unit 32, and an operation unit 33, for example. The wireless communication unit 31 connects to the Internet 2 using a mobile phone line or a wireless LAN line, and performs data communication with the game server 1 on a web browser. The display unit 32 displays the web browser screen received from the game server 1. For example, the operation unit 33 includes a touch panel that receives an operation input from an actual user according to the display on the screen of the display unit 32. The operation input received from the real user in this way is transmitted to the game server 1 by the wireless communication unit 31.

  In the terminal 3 having such a hardware configuration, for example, individual authentication processing of the terminal is performed by a combination of a user ID registered in advance and a predetermined password. When the authentication with the game server 1 is completed, the terminal 3 receives data necessary for progressing the game from the game server 1 and transmits operation data in the operation unit 33 to the game server 1. .

  The terminal 3 may be a mobile phone, a PDA, a personal computer, or the like as long as it is a communication device that can communicate with the game server 1 via the Internet 2 that is a communication network. In addition, although a touch panel has been described as an example of the operation unit 33, it is needless to say that a configuration in which a cursor or the like is moved by a physical key operation to perform selection operation and input information may be employed.

(3-2) Schematic Configuration of Game Server The game server 1 connected to be communicable with the terminal 3 is realized by a computer having a general-purpose hardware configuration as shown in FIG. 3, for example. That is, the game server 1 includes a communication interface unit 11 that communicates with the terminal 3 via the Internet 2 and an operation input unit 12 that receives an operation input from a user such as a keyboard and a mouse, as shown in FIG. . In addition, the game server 1 includes an arithmetic processing unit 13 such as a CPU that performs various arithmetic processes, a main memory 14 such as an SRAM or DRAM that temporarily stores arithmetic processing data, and a hard disk that stores application programs and various data. And the like, and a display 16 for displaying the calculation processing result.

(4) First Embodiment The game server 1 (hereinafter referred to as the game server 1a to be distinguished from other embodiments) installs a program for providing such a social game 20 to the user in the storage device 15. Thus, a functional block as shown in FIG. 4 is realized.

  That is, in the game server 1a, for example, a function including an operation data receiving unit 11a, a game data processing unit 100, and a game data storage unit 200 that manages game data is realized as shown in FIG.

  The operation data receiving unit 11 a is means for receiving operation data transmitted from the terminal 3 through the communication network 2. The game data processing unit 100 includes a quest part processing unit 101, a battle part processing unit 102, a gacha part processing unit 103, and an enhanced part processing unit 104.

  Here, the quest part processing unit 101 performs data processing of the quest part 21. The battle part processing unit 102 performs data processing for the battle part 22. The gacha part processing unit 103 performs data processing of the gacha part 23. The reinforcement part processing unit 104 performs data processing of the reinforcement part 24.

(4-1) Specific Configuration of Game Server In the following, the gacha part processing unit 103 having a configuration specific to the first embodiment and game data serving as a storage area for realizing processing in the gacha part processing unit 103 A specific configuration of the storage unit 200 will be described with reference to FIG. First, the configuration of the game data storage unit 200 will be described.

(4-1-1) Configuration of Game Data Storage Unit First, as data used in the gacha part processing unit 103, the game data storage unit 200 includes an item data table 211 and a virtual user data storage unit as shown in FIG. 210.

(Item data table 211: FIG. 6)
As shown in FIG. 6, the item data table 211 manages a list of virtual items that can be used in the game.

  Each virtual item is given a unique number for each item as an “item ID”.

  Each virtual item has a parameter indicating the rarity value of the item “rareness”.

  The “rareness” indicates a rarity value of an item, and is a parameter attached to the item. The rarity value is determined by the degree of distribution in the game and the probability that the virtual user acquires in the game. That is, a virtual item with a higher degree of scarcity has a smaller amount of circulation in the game. In addition, a virtual item with a higher degree of rarity has a lower probability of being acquired by a virtual user by purchasing a gacha right. As shown in FIG. 6, the rarity is set, for example, in five stages. The lowest rarity is represented by “1” and the highest rarity is represented by “5”. Some games are called normal (N), rare (R), S rare (SR), SS rare (SSR), and SSS rare (SSSR) in ascending order of rarity. A virtual item with a high degree of rarity is advantageous when playing a game, such as exhibiting a high attack power in a battle with an enemy appearing in the game.

  The “item image” is image data representing a virtual item, and display processing data in which such image data is incorporated is transmitted from the game server 1 to the terminal 3.

  The virtual user data storage unit 210 includes a purchase history data table 221A, a price reduction condition data table 222A, a price setting data table 223A, and an owned item data table 224.

(Purchase history data table 221A: FIG. 7)
As illustrated in FIG. 7, the purchase history data table 221 </ b> A stores data related to a purchase history of gacha rights performed by a virtual user for each virtual user. In the purchase history data table 221A, every time a purchase of a gacha right is received from a terminal that operates a virtual user, the time when the purchase is received (gacha right purchase time) and the purchase price are stored. Gacha right purchase time is represented by date and time.

(Price reduction condition data table 222A: FIG. 8)
As shown in FIG. 8, the price reduction condition data table 222 </ b> A stores data on conditions for reducing the purchase price of gacha right for each virtual user. The price setting unit described later reduces the purchase price of the gacha right by the virtual user when the virtual user satisfies a condition set for the virtual user.

  The condition content is expressed by a unit period and a specified number of times. The unit period means a period divided by a predetermined unit. The specified number of times means the minimum number of times necessary to clear the condition. For example, the condition set for the virtual user with the user ID 30001 is a condition of purchasing a gacha right at least once a day. The day break is not particularly limited, but is, for example, 0:00.

  The discount amount means an amount deducted from the purchase price of the gacha right that is currently set when the condition is satisfied.

(Price setting data table 223A: FIG. 9)
As shown in FIG. 9, the price setting data table 223 </ b> A stores data related to the purchase price of gacha right for each virtual user. The real user can acquire the gacha right by paying an amount corresponding to the purchase price.

(Owned item data table 224: FIG. 10)
As shown in FIG. 10, the owned item data table 224 stores identification information of virtual items owned by the virtual user for each virtual user. Specifically, the owned item data table 224 of FIG. 10 stores the number of virtual items owned for each item ID.

  From FIG. 10, it can be seen that, for example, the virtual user with the user ID 30001 owns one virtual item with the item ID 10001.

(4-1-2) Configuration of Gacha Part Processing Unit As shown in FIG. 5, the gacha part processing unit 103 includes a price setting unit 41, a price display unit 42, a purchase receiving unit 43, and an item setting unit 44. .

  The price setting unit 41 is a means for setting the price required to purchase the virtual item acquisition right in the virtual space, and sets the price of the item acquisition right based on the purchase history information of the item acquisition right by the virtual user. . Specifically, when the virtual user has no purchase history, the price setting unit 41 sets the item acquisition right to a predetermined price determined in advance. In addition, the price setting unit 41 changes the price of the item acquisition right to a price lower than the predetermined price when the purchase receiving unit 43 described later receives the purchase of the item acquisition right a predetermined number of times in a predetermined unit period. . Further, the price setting unit 41 changes the price of the item acquisition right to a price lower than the predetermined price, and if the purchase of the item acquisition right received during the predetermined unit period is less than the predetermined number of times, The right price is changed to a higher price than the changed price.

  The price setting unit 41 is a means for determining a price reduction condition according to the attribute of the virtual user. For example, after setting the item acquisition right to a predetermined price, the price setting unit 41 determines the price reduction condition according to the attribute of the virtual user. Specifically, the price setting unit 41 determines the price reduction condition so that the predetermined number of times per unit period increases as the attribute value unique to the virtual user increases. The attribute value unique to the virtual user is, for example, the number of virtual items whose level and rarity are equal to or higher than a predetermined threshold.

  The price display unit 42 is a means for displaying the purchase price when each virtual user purchases a gacha right on each terminal that operates each virtual user. The purchase price varies depending on predetermined conditions. Therefore, the price display unit 42 may display a purchase price and a condition for changing the purchase price. For example, an image stating “If you purchase a gacha right within the remaining XX minutes, the purchase price will be reduced by 20 yen” or “If you do not purchase a gacha right within the remaining XX minutes, the purchase price will increase by 20 yen” The described image is displayed.

  The purchase acceptance unit 43 is means for accepting purchase of a gacha right based on operation data received from a terminal.

  When the purchase accepting unit 43 accepts the purchase of the gacha right, the item setting unit 44 selects a virtual item at random based on the appearance rate set in advance for each virtual item, and assigns the selected virtual item to the gacha right. It is a means to set as an owned item of the purchased virtual user.

(4-2) Processing in Game Server As an example of processing in the game server 1a of the present embodiment, processing of the gacha part processing unit 103 having the above configuration will be described.

(4-2-1) Overview of Processing in Gacha Part Processing Unit First, an overview of processing in the gacha part processing unit 103 will be described with reference to FIG. First, in step S1101, the price setting unit 41 performs a process (price setting process) for setting a purchase price when each virtual user purchases a gacha right for each virtual user registered in the game. . Details of the price setting process will be described later.

  In step S1102, the price display unit 42 displays the purchase price set for each virtual user in step S1101, that is, the purchase price stored in the price setting data table 223A of FIG. indicate. Thereby, each real user who operates each virtual user can know the amount of money required to purchase the gacha right.

  In step S1103, the purchase acceptance unit 43 determines whether or not the purchase of the gacha right has been accepted based on the operation data received from the terminal. Specifically, the purchase acceptance unit 43 determines whether payment for the purchase price set in step S1101 has been made in order to purchase a gacha right. When the purchase of the gacha right is accepted (step S1103: YES), the process proceeds to step S1104. On the other hand, when the purchase of the gacha right is not accepted (step S1103: NO), the process of step S1103 is repeated.

  In step S1104, the item setting unit 44 randomly selects a virtual item from the virtual items stored in the item data table 211 of FIG.

  In step S1105, the item setting unit 44 sets the virtual item selected in step S1104 as the possessed item of the virtual user who purchased the gacha right. Specifically, the item setting unit 44 rewrites the data stored in the owned item data table 224 of FIG.

(4-2-2) Price Setting Process Details of the price setting process in step S1101 will be described with reference to FIG. This price setting process is a process executed for each virtual user. Below, it demonstrates as a process with respect to the arbitrary one virtual users (henceforth "target virtual user") registered into the game. The price setting process is executed at an arbitrary timing. Preferably, it is executed every time the unit period elapses. Here, the unit period is one day, and the unit period is switched on the basis of 0:00.

  In step S1201, the price setting unit 41 refers to the purchase history data table 221A of FIG. 7 and determines whether or not the target virtual user has a purchase history of gacha rights. If there is a purchase history (step S1201: YES), the process proceeds to step S1202. On the other hand, if there is no purchase history (step S1201: NO), the process proceeds to step S1208.

  In step S1202, the price setting unit 41 reads the price reduction condition of the target virtual user with reference to the price reduction condition data table 222A of FIG.

  For example, the price reduction condition set for the virtual user with the user ID 30001 from the price reduction condition data table 222A of FIG. 8 is a condition that the gacha right is purchased once a day.

  In step S1203, the price setting unit 41 refers to the purchase history data table 221A of FIG. 7 and determines whether or not the target virtual user satisfies the price reduction condition. Specifically, the price setting unit 41 determines whether or not the purchase of the gacha right has been received a predetermined number of times in the unit period. If the price reduction condition is satisfied (step S1203: YES), the process proceeds to step S1204. On the other hand, if the price reduction condition is not satisfied (step S1203: NO), the process proceeds to step S1205.

  For example, it is assumed that this price setting process is executed when 0:00 on November 4, 20xx has passed. If it is a virtual user of user ID 30001, it turns out from the purchase history data table 221A of FIG. 7 that he has purchased a gacha right once on November 3, 20xx. Therefore, the virtual user with the user ID 30001 satisfies the condition that the gacha right is purchased once a day.

  In step S1204, the price setting unit 41 executes processing (price reduction processing) for changing the purchase price of the gacha right currently set for the target virtual user to a price relatively lower than the purchase price. Details of the price reduction process will be described later.

  In step S1205, the price setting unit 41 determines whether or not the purchase price of the gacha right currently set for the target virtual user is the initial price. If it is the initial price (step S1205: YES), the process proceeds to step S1210. That is, if the price is the initial price, the price increase process described later is not executed, and the purchase price of the gacha right is maintained as the initial price. On the other hand, if it is not the initial price (step S1205: NO), the process proceeds to step S1206.

  The initial price is a predetermined price (for example, 300 yen) set in advance for each virtual user. In the price reduction process described later, the price is gradually reduced from the initial price. In the price increase process described later, the price is increased so as not to be higher than the initial price.

  In step S1206, the price setting unit 41 executes a process (price increase process) for changing the purchase price of the gacha right currently set for the target virtual user to a price relatively higher than the purchase price. Details of the price increase process will be described later.

  In step S <b> 1207, the price setting unit 41 determines whether or not the purchase price after executing the price increase process has become the initial price. If it is the initial price (step S1207: YES), the process proceeds to step S1210. On the other hand, when the price is not the initial price (step S1207: NO), this process ends.

  In step S1208, the price setting unit 41 sets the purchase price of the gacha right as the initial price for the target virtual user.

  In step S1209, the price setting unit 41 associates the identification information (user ID) of the target virtual user with the initial price and stores it in the price setting data table 223A of FIG.

  In step S1210, the price setting unit 41 determines a price reduction condition according to the attribute information of the target virtual user. Specifically, the price reduction condition is set so that the specified number of times per unit period increases as the number of virtual users owned increases for virtual items with a rarity level equal to or higher than a predetermined threshold. For example, a virtual user who does not own a virtual item with a rarity “5” is at least once a day, and a virtual user who has 1 to 4 virtual items with a rarity “5” If a virtual user who owns 5-8 virtual items with a rarity level of “5” at least twice purchases a gacha right three times a day, a condition is set that the purchase price of the gacha right decreases. The

  The process of step S1210 is executed when the target virtual user has no purchase history of gacha right and an initial price is set as the purchase price of gacha right. Thus, when the purchase price of the gacha right is set for the target virtual user for the first time, the price reduction condition is determined for the target virtual user. The process of step S1210 is also executed when the purchase price of the gacha right is maintained at the initial price and when the purchase price after the price increase process is the initial price. As described above, when the initial price is reset as the purchase price of the gacha right for the target virtual user, the price reduction condition for the target virtual user is determined again. Conversely, when a price other than the initial price is set as the purchase price for the gacha right, the price reduction condition for the target virtual user is maintained without being determined again.

  In step S1211, the price setting unit 41 associates the identification information (user ID) of the target virtual user with the price reduction condition set in step S1210 and stores it in the price reduction condition data table 222A of FIG.

(4-2-3) Modified Example of Price Setting Process In the price setting process, specific contents of the price reduction condition are determined for each virtual user (step S1210), and whether or not the price reduction condition is satisfied is determined. Although an example of determination (step S1203) has been shown, the price reduction condition may be common to all virtual users. As shown in FIG. 13, in step S1310, the price setting unit 41 selects an arbitrary price reduction condition from among price reduction conditions stored in advance in the storage unit. In step S1302, a process (condition determination process) is performed to determine whether the target virtual user satisfies the price reduction condition selected in step S1310. If it is determined in step S1302 that the price reduction condition is satisfied (step S1303: YES), the process proceeds to step S1304, and if it is not determined in step S1302 that the price reduction condition is satisfied (step S1303). : NO), the process proceeds to step S1305. Details of the condition determination process will be described later. Note that the processes in steps S1301 and S1304 to S1309 are the same as those in steps S1201 and S1204 to S1209.

(4-2-4) Condition Determination Processing Specific examples 1 to 4 of the condition determination processing in step S1302 will be described with reference to FIGS.

[Specific Example 1]
As shown in FIG. 14A, in step S1401, the price setting unit 41 refers to the purchase history data table 221A shown in FIG. 7, and calculates the purchase amount for which the target virtual user purchased the gacha right for a predetermined period. .

  In step S <b> 1402, the price setting unit 41 calculates the number of acquisitions of the virtual item with the rarity “5” acquired by the target virtual user purchasing a gacha right during a predetermined period. In other words, the number of times that the item setting unit 44 selects a virtual item with a rarity “5” and sets it as the possessed item of the virtual user is calculated for the purchase of the gacha right by the target virtual user in a predetermined period. To do. The predetermined period is, for example, one week or one month. The predetermined period in step S1401 and the predetermined period in step S1402 are the same period.

  In step S1403, the price setting unit 41 determines whether the number of acquisitions calculated in step S1402 for the purchase amount calculated in step S1401 is equal to or less than a predetermined threshold. For example, if the predetermined threshold is set to 1 acquisition for a purchase amount of 1000 yen, is the number of acquisitions less than 1 by dividing the purchase amount calculated in step S1401 by 1000 yen? Judge whether or not. If it is equal to or less than the predetermined threshold (step S1403: YES), the process proceeds to step S1404, it is determined that the price reduction condition is satisfied, and this process is terminated. On the other hand, if the predetermined threshold value is exceeded (step S1403: NO), this process is terminated without determining that the price reduction condition is satisfied.

[Specific Example 2]
As illustrated in FIG. 14B, in step S1411, the price setting unit 41 calculates the winning percentage of the target virtual user in a predetermined period based on the battle history information of the target virtual user. The battle is performed, for example, on a one-to-one basis between virtual users. Winning or losing is determined by the battle ability value based on the virtual item owned by each virtual user. The higher the rarity attached to the virtual item, the higher the battle ability value. That is, a virtual user who owns many virtual items with a high degree of rarity is more likely to win a battle.

  In step S1412, the price setting unit 41 determines whether or not the winning percentage calculated in step S1411 is equal to or less than a predetermined threshold. If it is equal to or less than the predetermined threshold (step S1412: YES), the process proceeds to step S1413. On the other hand, if the predetermined threshold value is exceeded (step S1412: NO), this process ends without determining that the price reduction condition is satisfied.

  In step S <b> 1413, the price setting unit 41 refers to the purchase history data table 221 </ b> A of FIG. 7 and calculates the purchase amount for which the target virtual user purchased the gacha right during a predetermined period. The predetermined period in step S1411 and the predetermined period in step 1413 are the same period.

  In step S1414, the price setting unit 41 determines whether the purchase amount calculated in step S1413 is equal to or greater than a predetermined threshold value. If it is equal to or greater than the predetermined threshold (step S1414: YES), the process proceeds to step S1415, determines that the price reduction condition is satisfied, and ends this process. On the other hand, if it is less than the predetermined threshold value (step S1414: NO), this process ends without determining that the price reduction condition is satisfied.

[Specific Example 3]
As shown in FIG. 15A, in step S1501, the price setting unit 41 refers to the purchase history data table 221A of FIG. 7, and the purchase amount purchased by the target virtual user during the first predetermined period is the gacha right. Is calculated.

  In step S1502, the price setting unit 41 refers to the purchase history data table 221A shown in FIG. 7 and calculates the purchase amount for which the target virtual user has purchased the gacha right during the second predetermined period. The second predetermined period is a period after the first predetermined period. Further, the first predetermined period and the second predetermined period are equivalent periods (for example, one week).

  In step S1503, the price setting unit 41 determines whether or not the purchase amount in the second predetermined period is larger than the purchase amount in the first predetermined period. If the former is greater than the latter (step S1503: YES), the process proceeds to step S1504, it is determined that the price reduction condition is satisfied, and the present process is terminated. On the other hand, when the former and the latter are the same, or when the latter is greater than the former (step S1503: NO), this process is terminated without determining that the price determination condition is satisfied.

[Specific Example 4]
As shown in FIG. 15B, in step S1511, the price setting unit 41 reads the virtual item most recently acquired by the target virtual user by purchasing the gacha right. In other words, the item setting unit 44 reads out the virtual item set as the possessed item of the target virtual user for purchase in the latest gacha right by the target virtual user.

  In step S1512, the price setting unit 41 determines whether the virtual item read in step S1511 is related to the virtual item constructed as the target virtual user's deck. The deck is a predetermined number of virtual item groups selected from virtual items owned by the virtual user. The deck is constructed based on operation data from the terminal. For example, when a specific game function is expressed by combining the virtual item read in step S1511 and any virtual item constructed as the target virtual user's deck, each virtual item is related. It can be said that. If it is related to the virtual item constructed as a deck (step S1512: YES), the process proceeds to step S1513, it is determined that the price reduction condition is satisfied, and this process is terminated. On the other hand, when it is not related to the virtual item constructed as a deck (step S1512: NO), this process ends without determining that the price determination condition is satisfied.

  In addition, the condition determination process of the said specific examples 1 and 2 is performed whenever a predetermined period passes. Further, the condition determination process of the specific example 3 is performed every time the next predetermined period elapses after the price reduction condition is determined and the first predetermined period elapses. Moreover, the condition determination process of the said specific example 4 is performed whenever a virtual user acquires a virtual item by purchase of a gacha right. In the specific examples 1 to 3, the purchase price may be replaced with the number of purchases. Data relating to the number of purchases in a predetermined period is obtained from the purchase history data table 221A in FIG.

  In the present embodiment, the price reduction condition may be one or a combination of two or more. For example, the price setting process shown in FIG. 12 and the price setting process shown in FIG. 13 may be combined. Specifically, the price reduction condition is determined according to the attribute of the target virtual user (step S1210), and any price reduction condition may be selected from the price reduction conditions stored in advance in the storage unit ( Step S1310). Further, a plurality of price reduction conditions may be selected in step S1310.

(4-2-5) Price Reduction Process Details of the price reduction process in steps S1204 and S1304 will be described with reference to FIG. In step S1601, the price setting unit 41 reads the currently set purchase price from the price setting data table 223A of FIG.

  For example, it can be seen from the price setting data table 223A of FIG. 9 that the purchase price currently set for the virtual user with the user ID 30001 is 260 yen.

  In step S1602, the price setting unit 41 reads the discount amount from the price reduction condition data table 222A of FIG.

  For example, the price reduction condition data table 222A in FIG. 8 indicates that the discount amount set for the virtual user with the user ID 30001 is 20 yen.

  In step S1603, the price setting unit 41 sets a new price by subtracting the discount amount read in step S1602 from the purchase price read in step S1601.

  For example, if the currently set purchase price is 260 yen and the discount amount is 20 yen, the new price is 240 yen.

  In step S1604, the price setting unit 41 rewrites the purchase price stored in the price setting data table 223A of FIG. 9 with the new price set in step S1603.

(4-2-6) Price Increase Processing Details (specific examples 1 to 3) of the price increase processing in steps S1206 and S1306 will be described with reference to FIGS. Specific example 1 is an example in which the purchase price is increased to the initial price all at once, and specific examples 2 and 3 are examples in which the purchase price is increased stepwise. In specific examples 2 and 3, the purchase price is increased by replacing the discount amount stored in the price reduction condition data table 222A of FIG.

(Specific example 1)
As shown in FIG. 17A, in step S1701, the price setting unit 41 sets the initial price as a new price.

  In step S1702, the price setting unit 41 rewrites the purchase price stored in the price setting data table 223A of FIG. 9 to the initial price.

(Specific example 2)
As shown in FIG. 17B, in step S1711, the price setting unit 41 reads the currently set purchase price from the price setting data table 223A of FIG.

  For example, it can be seen from the price setting data table 223A in FIG. 9 that the purchase price currently set for the virtual user with the user ID 30002 is 240 yen.

  In step S1712, the price setting unit 41 reads the discount amount from the price reduction condition data table 222A of FIG.

  For example, the price reduction condition data table 222A in FIG. 8 indicates that the discount amount set for the virtual user with the user ID 30002 is 20 yen.

  In step S1713, the price setting unit 41 sets a new price by adding the discount amount read in step S1712 to the purchase price read in step S1711. When the calculated price exceeds the initial price, the initial price is set as a new price.

  For example, if the discount amount is 20 yen and the currently set purchase price is 240 yen, the new price is 260 yen.

  In step S1714, the price setting unit 41 rewrites the purchase price stored in the price setting data table 223A of FIG. 9 with the new price set in step S1713.

(Specific example 3)
As shown in FIG. 17C, in step S1721, the price setting unit 41 reads the currently set purchase price from the price setting data table 223A of FIG.

  For example, it can be seen from the price setting data table 223A in FIG. 9 that the purchase price currently set for the virtual user with the user ID 30002 is 240 yen.

  In step S1722, the price setting unit 41 reads the specified number of times per unit period and the discount amount from the price reduction condition data table 222A of FIG.

  For example, it can be seen from the price setting data table 223A of FIG. 9 that the prescribed number of times per unit period set for the virtual user with the user ID 30002 is 2 and the discount amount is 20 yen.

  In step S1723, the price setting unit 41 refers to the purchase history data table 221A in FIG. 7 and reads the number of purchases of the gacha right in the unit period.

  For example, the description will be made assuming that the price setting process is executed at the time when 0 o'clock on November 4, 20xx has passed. If it is a virtual user of user ID 30002, it can be seen from the purchase history data table 221A of FIG. 7 that a gacha right is purchased once on November 3, 20xx.

  In step S1724, the price setting unit 41 calculates the ratio of the shortage number read in step S1723 to the prescribed number read in step S1722. The number of shortages can be obtained by subtracting the number of purchases from the specified number of times. For example, if the specified number of times is two and the number of purchases is one, the number of shortages is one. Therefore, the ratio of the shortage to the specified number is 50%.

  In step S1725, the price setting unit 41 multiplies the discount amount read in step S1722 by the ratio calculated in step S1724, and adds the obtained amount to the purchase price read in step S1721, thereby creating a new value. Set the price. The amount of addition increases as the ratio of the shortage increases. In other words, the additional amount decreases as the number of purchases increases. When the calculated price exceeds the initial price, the initial price is set as a new price.

  For example, if the discount amount is 20 yen, the ratio of the number of purchases to the specified number of times is 50%, and the currently set purchase price is 240 yen, the new price is 250 yen.

  In step S1726, the price setting unit 41 rewrites the purchase price stored in the price setting data table 223A of FIG. 9 with the new price set in step S1725.

(4-3) Effect In the first embodiment, the purchase price of the gacha right varies depending on the purchase history of the gacha right by the virtual user. Depending on the purchase history of the gacha right, the actual user can pay less to obtain the gacha right, and can acquire the virtual item with a small amount. As a result, it is possible to stimulate the real user who wants to purchase the gacha right with a smaller amount of money and guide the user to purchase the gacha right.

  According to the price reduction process of the first embodiment, when a real user purchases a gacha right at least a predetermined number of times in a predetermined unit period, the purchase price of the gacha right decreases. Thereby, in order to reduce the purchase price of the gacha right, the real user can be guided to purchase the gacha right a predetermined number of times in a predetermined unit period. In addition, if a real user purchases a gacha right a predetermined number of times during a predetermined unit period and then purchases a predetermined number of times during the next predetermined unit period, the purchase price of the gacha right continuously decreases. Thereby, a real user can be guided to purchase gacha right continuously.

  According to the price increase process of the first embodiment, the purchase price of the gacha right increases unless the gacha right is purchased at least a predetermined number of times in a predetermined unit period. As a result, it is possible to drive the real user who wants to purchase the gacha right with a smaller amount of money and to guide the user to purchase the gacha right continuously.

  In particular, in the specific example 1 of the price increase process, if the gacha right is not purchased at least a predetermined number of times in a predetermined unit period, the purchase price of the gacha right returns to the initial price all at once. Thereby, it is possible to guide the real user to purchase the gacha right continuously.

  Further, in the specific example 2 of the price increase process, if the gacha right is not purchased at least a predetermined number of times in a predetermined unit period, the purchase price of the gacha right gradually approaches the initial price. The longer the gacha right is purchased and the greater the discount amount, the longer it takes to return to the initial price. Since the price decrease rate and the price increase rate are the same, the motivation of the real user for the purchase of the gacha right can be maintained.

  Further, in specific example 3 of the price increase process, the degree of increase in the purchase price of the gacha right varies depending on the number of purchases. Even if the gacha right cannot be purchased a predetermined number of times in a predetermined unit period, the degree of increase becomes smaller as the number of purchases increases, so that the real user can be motivated to purchase more gacha right even once. .

  In the first embodiment, even if the gacha right is not purchased at least a predetermined number of times in a predetermined unit period, the purchase price is not set beyond the initial price. That is, the purchase price set for the actual user is the initial price or a price lower than the initial price. Thereby, a real user can be made to play a game in comfort.

  In the first embodiment, the price reduction condition is set so that the prescribed number of times per unit period increases as the attribute value unique to the virtual user increases. Usually, the attribute value unique to the virtual user increases in proportion to the time that the real user plays the game. That is, a virtual user with a higher attribute value is an advanced user, and a virtual user with a lower attribute value is a beginner user. By setting the price reduction condition easily so that the specified number of times per unit period is reduced for the novice user, the novice user can be guided to purchase the gacha right. By making the novice user feel the pleasure of acquiring a virtual item by purchasing a gacha right, the user can be guided to purchase the gacha right continuously.

  In particular, in the first embodiment, the price setting unit determines the price reduction condition as the purchase price of the gacha right is set to the initial price. That is, when the purchase price of the gacha right is maintained at the initial price, and when the purchase price of the gacha right is reduced and then returned to the initial price, the price reduction condition is determined again. As the attribute value specific to the virtual user increases, the specified number of times per unit period increases. The actual user can recognize that it is advantageous to purchase the gacha right while the prescribed number of times per unit period is set to be small, and the purchase of the gacha right by the real user can be promoted.

  On the other hand, in the first embodiment, when the price setting unit sets a price other than the initial price as the purchase price of the gacha right, the price reduction condition is not determined again. Therefore, even if the attribute value unique to the virtual user is high, the price reduction condition is not changed. Thereby, the purchase price of the gacha right by the actual user can be promoted so that the purchase price of the gacha right returns to the initial price again and is not changed to a strict price reduction condition.

  Moreover, in the specific example 1 of the condition determination process of the first embodiment, when the number of times the virtual item having the rarity “5” is acquired is equal to or less than a predetermined threshold with respect to the purchase amount of the gacha right in a predetermined period, It is determined that the price reduction condition is satisfied. A virtual item with a high degree of rarity is highly demanded by real users. Even if the gacha right is continuously purchased, if a virtual item with a high degree of rarity cannot be obtained, the willingness of the real user to purchase the gacha right may decrease. Therefore, for virtual users who have purchased a lot of gacha rights but have not acquired a rare virtual item, continue to purchase gacha rights by reducing the purchase price of gacha rights. Can maintain motivation.

  In the specific example 2 of the condition determination process of the first embodiment, when the price reduction condition is satisfied when the winning rate in a predetermined period is equal to or less than a predetermined threshold and the purchase amount of the gacha right is equal to or greater than the predetermined threshold. Determined. In order to win in-game battles, you need to own more virtual items with a high degree of rarity. Real users purchase gacha rights in the hope that they can acquire virtual items with a high degree of rarity. However, it is highly possible that a virtual item with a high degree of rarity has not been acquired because it is not possible to win a battle despite purchasing many gacha rights. If a virtual item with a high degree of rarity cannot be acquired, the real user's willingness to purchase a gacha right may decrease. Therefore, by reducing the purchase price of the gacha right for a virtual user with a low win rate and a large purchase price, it is possible to maintain the willingness to continue to purchase the gacha right.

  In specific example 3 of the condition determination process of the first embodiment, it is determined that the price reduction condition is satisfied when the purchase amount in the second predetermined period is larger than the purchase amount in the first predetermined period. Usually, when a virtual user acquires a virtual item, the in-game level of the virtual user increases. By gradually increasing the purchase amount each time the predetermined period elapses, the gacha right can be provided at a purchase price corresponding to the in-game level of the virtual user.

  In the specific example 4 of the condition determination process of the first embodiment, when the virtual item newly acquired by the target virtual user by purchasing the gacha right is not a virtual item related to the virtual item constructed as a deck, the price decreases It is determined that the condition is satisfied. The deck is constructed by a real user freely selecting a predetermined number of virtual items from virtual items owned by the virtual user. Usually, in an in-game battle, the winning or losing is determined by the total value of the attack power exhibited by the virtual items constructed as a deck. Therefore, the real user desires to acquire a virtual item that can increase the attack power exhibited by the virtual item constructed as a deck. For example, if the attack power is increased by combining virtual items of the same type, the real user has a high desire to acquire a virtual item of the same type as the virtual item constructed as a deck. In addition, if the virtual item is classified into a plurality of attributes and the attack power is increased by combining virtual items with the same attribute, the real user selects the same type of virtual item as the virtual item constructed as a deck. High desire to get. A real user is considered to purchase a gacha right in the hope that a virtual item related to the virtual item constructed as a deck can be acquired. Therefore, if the virtual item newly acquired by purchasing the gacha right is not a virtual item related to the virtual item constructed as a deck, the desire to continue to purchase the gacha right by reducing the purchase price of the gacha right Can be increased.

(4-4) Modified Example of First Embodiment In the above embodiment, when the target virtual user does not satisfy the predetermined price reduction condition, the process of increasing the purchase price of the gacha right set for the target virtual user However, the purchase price may be maintained according to a gacha right purchase history by a virtual user who is in a peer relationship with the target virtual user. For example, when a virtual user who has a friendship with the target virtual user has purchased a gacha right more than a predetermined number of times in a unit period, the price setting unit may maintain the purchase price.

  Note that the setting of “mate” in the game is performed when one virtual user makes a friend application to another virtual user and the other requested virtual user approves it. A fellow relationship means a relationship between virtual users who have performed such peer application and approval. It is not particularly limited as long as it means a word “friend”, and it may be expressed by the words “friend”, “friend”, and “XX friend”.

  Further, an upper limit setting unit (not shown) sets an upper limit value of the purchase price for a predetermined period based on information registered in the terminal operating the virtual user, and the purchase price of the virtual user for the predetermined period is When the set upper limit value is exceeded, the price setting unit may return the purchase price of the gacha right to the initial price. The information registered in the terminal includes, for example, age, and the upper limit value of the purchase price is set according to age. Data relating to the purchase price of the virtual user in the predetermined period is obtained from the purchase history data table 221A of FIG. By reducing the purchase price of the gacha right based on the predetermined condition, the willingness of the actual user to purchase the gacha right can be improved. However, if too many gacha rights are purchased in a predetermined period, it may be difficult for an actual user to purchase gacha rights continuously. Therefore, when the set upper limit value is exceeded, the purchase price of the gacha right is returned to the initial price, thereby suppressing the purchase of the gacha right at a stretch within a predetermined period and continuously purchasing the gacha right to the real user. Can be encouraged. By continuously purchasing gacha rights, the game can be played continuously. Note that the information is not limited to a terminal, and may be registered in a game server.

  In addition, a trade-related calculation unit (not shown) calculates the usage rate of the virtual item with the rarity “5” acquired by the virtual user by purchasing the gacha right, and the usage rate is set to a predetermined threshold. If it exceeds, the price change prohibition unit (not shown) may prohibit the purchase price of the gacha right from being reduced. Trade refers to exchanging a virtual item owned by a virtual user with a virtual item owned by another virtual user in the game. In the trade, generally, a virtual item arbitrarily selected from the virtual items owned by both virtual users is set as a trade target. By trading, one virtual user loses the virtual item owned by himself / herself set as a trade target, and acquires a virtual item owned by another virtual user set as a trade target. Since acquiring a virtual item with a high degree of rarity can advantageously advance the game, the real user does not let go of the virtual item with a high degree of rarity much. Accordingly, it is highly likely that a real user who has just let go of a virtual item with a high degree of rarity acquired by purchasing a gacha right has purchased the gacha right for the purpose of real money trade (RMT). Therefore, when a virtual item with a high degree of rarity is used for trading with a high probability, the purchase of a gacha right for the purpose of RMT can be suppressed by prohibiting the purchase price from being lowered. Note that the predetermined threshold value is, for example, the average value of the usage rate used for trading virtual items with a rarity “5” acquired by purchasing gacha rights for all virtual users registered in the game. Can do. Further, the predetermined threshold value may be set to 50% in order to allow a virtual user to use up to half of the number of virtual items of rarity “5” acquired by purchasing a gacha right. In addition, the predetermined threshold may be set to 0% in order to prevent real money trade (RMT) and perform a sound trade.

  In the above-described embodiment, an example in which the unit period is one day and the specified number of times is different is shown as the price reduction condition. However, the unit period is not limited to one day. For example, the price reduction condition may be set so that the unit period becomes shorter as the number of virtual users owned increases for virtual items with a rarity level equal to or higher than a predetermined threshold. Specifically, a virtual user who does not own a virtual item with a rarity “5” is at least once a day, and a virtual user who has 1 to 4 virtual items with a rarity “5” is 6 A condition is set that a virtual user who owns 5 to 10 virtual items with a rarity level “5” at least once per hour will purchase a gacha right at least once an hour, and the purchase price of the gacha right will decrease. Is done.

(5) Second Embodiment (5-1) Specific Configuration of Game Server As shown in FIG. 18, the game server 1b according to the second embodiment includes an appearance rate setting unit in the game server 1b according to the first embodiment. 45 is provided. In the second embodiment, unlike the first embodiment, the appearance rate setting unit 45 sets an appearance rate for each virtual item, and the item setting unit 44 selects a virtual item based on the set appearance rate.

  In the first embodiment, the price setting unit 41 sets the purchase price of the gacha right for each virtual user, whereas in the second embodiment, the purchase price of the gacha right is set for each team. Therefore, the game data storage unit 200 includes a team data table 212, a virtual user data storage unit 210, and a team data storage unit 220 in addition to the item data table 211. The virtual user data storage unit 210 includes an owned item data table 224, and the team data storage unit 220 includes a purchase history data table 221B, a price reduction condition data table 222B, and a price setting data table 223B. The description of the same configuration as that of the first embodiment will be omitted as appropriate.

(5-1-1) Configuration of Game Data Storage Unit (Team Data Table 212: FIG. 19)
As shown in FIG. 19, the team data table 212 stores identification information of virtual users belonging to teams in the game for each team. Each team is given a unique number as a “team ID”. By referring to the team data table 212 in FIG. 19, for example, it can be seen that a virtual user with user ID 30001 and a virtual user with user ID 30005 belong to the team with team ID 10001.

  The setting of “team” in the game is performed by creating a team by itself when registering in the game, or by joining a team that has already been created. The term “team” is not particularly limited, and the term “guild” may be used.

(Purchase history data table 221B: FIG. 20)
As illustrated in FIG. 20, the purchase history data table 221 </ b> B stores data on purchase history of gacha rights performed by a virtual user for each team. The purchase history data table 221B stores the identification information (user ID) of the purchased virtual user and the time of accepting the purchase (gacha right purchase time) every time the purchase of the gacha right is accepted from the terminal operating the virtual user. The Gacha right purchase time is represented by date and time.

(Price reduction condition data table 222B: FIG. 21)
As shown in FIG. 21, the price reduction condition data table 222B stores, for each team, data related to conditions for reducing the purchase price of gacha rights. The price setting unit reduces the purchase price of the gacha right by the virtual user when each virtual user belonging to the team cooperates and satisfies the conditions set for the team.

  The condition contents are represented by a unit period and a specified number of times, similar to the price reduction condition data table 222A of FIG. Similarly to the price reduction condition data table 222A of FIG. 8, the discount amount means an amount that is deducted from the currently set purchase price of the gacha right when the condition is satisfied.

(Price setting data table 223B: FIG. 22)
As shown in FIG. 22, the price setting data table 223B stores data on the purchase price of gacha right for each team. That is, the purchase price of each real user who operates each virtual user belonging to the same team is the same. Each real user can acquire a gacha right by paying an amount corresponding to the purchase price.

(5-1-2) Configuration of the gacha part processing unit The price setting unit 41 is a means for setting a price required to purchase a virtual item acquisition right in the virtual space, by a plurality of virtual users belonging to the team. This is means for setting the price of the item acquisition right based on the purchase history information of the item acquisition right. Specifically, when the team does not have a purchase history, the price setting unit 41 sets the item acquisition right to a predetermined price determined in advance. In addition, the price setting unit 41 changes the price of the item acquisition right to a price lower than the predetermined price when the purchase receiving unit 43 receives the purchase of the item acquisition right a predetermined number of times or more in a predetermined unit period. Further, the price setting unit 41 changes the price of the item acquisition right to a price lower than the predetermined price, and if the purchase of the item acquisition right received during the predetermined unit period is less than the predetermined number of times, The right price is changed to a higher price than the changed price.

  The price setting unit 41 is a means for determining a price reduction condition according to the team attribute. For example, after setting the item acquisition right to a predetermined price determined in advance, the price setting unit 41 determines the price reduction condition according to the attribute of the team. Specifically, the price reduction condition is set such that the higher the team-specific attribute value, the greater the predetermined number of times per unit period. The team-specific attribute value is, for example, the team level and the number of team battles won.

  Furthermore, the price setting unit 41 may determine the price reduction condition based on purchase history information of item acquisition rights by a plurality of virtual users belonging to the team. Specifically, the price setting unit determines that the number of virtual users who have purchased item acquisition rights during the period until the number of purchases reaches the specified number of times in the unit period. Price reduction conditions are determined so that

  When the purchase accepting unit 43 accepts the purchase of the gacha right, the item setting unit 44 randomly selects a virtual item based on an appearance rate set by an appearance rate setting unit 45 described later, and selects the selected virtual item as a gacha right. Is set as an item owned by the virtual user who purchased the.

  The appearance rate setting unit 45 is a means for setting the appearance rate of each virtual item so that the higher the team contribution to the purchase of the item acquisition right, the higher the appearance rate of the virtual item with a high degree of rarity. The team contribution is represented, for example, by the purchase frequency in a period until the number of purchases reaches a specified number of times in the latest unit period. The higher the purchase frequency, the higher the team contribution.

(5-2) Process in Game Server As an example of the process in the game server 1b of the present embodiment, the process of the gacha part processing unit 103 configured as described above will be described.

(5-2-1) Overview of Processing in Gacha Part Processing Unit First, an overview of processing in the gacha part processing unit 103 will be described with reference to FIG. First, in step S2301, the price setting unit 41 sets a purchase price when each virtual user belonging to each team purchases a gacha right for each team registered in the game (price setting process). ). Details of the price setting process will be described later.

  In step S2302, the price display unit 42 refers to the team data table 212 in FIG. 19 and the price setting data table 223B in FIG. 22, and displays the purchase price of the gacha right on each terminal that operates each virtual user. Since the purchase price of the gacha right is set for each team, the same price is displayed on each terminal that operates each virtual user belonging to the team.

  In step S2303, the purchase acceptance unit 43 determines whether or not the purchase of the gacha right has been accepted based on the operation data received from the terminal. Specifically, the purchase acceptance unit 43 determines whether payment for the purchase price has been made in order to purchase the gacha right. If the purchase of the gacha right is accepted (step S2303: YES), the process proceeds to step S2304. On the other hand, when the purchase of the gacha right is not accepted (step S2303: NO), the process of step S2303 is repeated. Hereinafter, the virtual user who purchased the gacha right in step 2303 will be described as a “purchased user”.

  In step S2304, the appearance rate setting unit 45 executes a process of setting the appearance rate of each virtual item (appearance rate setting process) in accordance with the team contribution to the purchase user's purchase of the gacha right. Details of the appearance rate setting process will be described later.

  In step S2305, the item setting unit 44 selects a virtual item at random from the virtual items stored in the item data table 211 of FIG. 6 based on the appearance rate set in step S2304.

  Since the process of step S2306 is the same as the process of step S1105, description thereof is omitted.

(5-2-2) Price Setting Processing Details of the price setting processing in step S2301 will be described with reference to FIG. This price setting process is a process executed for each team. Below, it demonstrates as a process with respect to the arbitrary one team (henceforth "target team") registered into the game. The price setting process is executed at an arbitrary timing. Preferably, it is executed every time the unit period elapses. Here, the unit period is one day, and the unit period is switched on the basis of 0:00.

  In step S2401, the price setting unit 41 refers to the purchase history data table 221B of FIG. 20 and determines whether or not the target team has a purchase history of gacha rights. If there is a purchase history (step S2401: YES), the process proceeds to step S2402. On the other hand, if there is no purchase history (step S2401: NO), the process proceeds to step S2408.

  In step S2402, the price setting unit 41 reads the price reduction condition of the target team with reference to the price reduction condition data table 222B of FIG.

  In step S2403, the price setting unit 41 refers to the purchase history data table 221B of FIG. 20 and determines whether or not the target team satisfies the price reduction condition. Specifically, the price setting unit 41 determines whether or not the purchase of the gacha right by the virtual user belonging to the target team has been performed more than the specified number of times in the unit period. If the price reduction condition is satisfied (step S2403: YES), the process proceeds to step S2404. On the other hand, if the price reduction condition is not satisfied (step S2403: NO), the process proceeds to step S2405.

  In step S2404, the price setting unit 41 executes a process (price reduction process) for changing the purchase price of the gacha right currently set for the target team to a price relatively lower than the purchase price. The price reduction process can be performed by the same method as in the first embodiment. Details are the same as the processing in step S1204 (specifically, the processing in steps S1601 to S1604), and thus the description thereof is omitted.

  In step S2405, the price setting unit 41 determines whether or not the purchase price of the gacha right currently set for the target team is the initial price. If it is the initial price (step S2405: YES), the process proceeds to step S2410. That is, if the price is the initial price, the price increase process described later is not executed, and the purchase price of the gacha right is maintained as the initial price. On the other hand, if it is not the initial price (step S2405: NO), the process proceeds to step S2406.

  In step S2406, the price setting unit 41 executes a process (price increase process) for changing the purchase price of the gacha right currently set for the target team to a price relatively higher than the purchase price. The price increase process can be performed by the same method as in the first embodiment. Details are the same as the processing in step S1206 (specifically, the processing in steps S1701 to S1702, the processing in steps S1711 to S1714, or the processing in steps S1721 to S1726), and thus the description thereof is omitted.

  In step S <b> 2407, the price setting unit 41 determines whether or not the purchase price after executing the price increase process has become the initial price. If it is the initial price (step S2407: YES), the process proceeds to step S2410. On the other hand, if the price is not the initial price (step S2407: NO), this process ends.

  In step S2408, the price setting unit 41 sets the purchase price of the gacha right as the initial price for the target team. Note that the initial price may be set based on the number of virtual users belonging to the team. For example, the initial price is set higher as the number increases.

  In step S2409, the price setting unit 41 associates the identification information (user ID) of the target team with the initial price and stores them in the price setting data table 223B of FIG.

  In step S2410, the price setting unit 41 determines price reduction conditions according to the attribute information of the target team. Specifically, the price reduction condition is set so that the prescribed number of times per unit period increases as the team level of the target team increases. For example, a team whose team level is 1 to 10 is 3 times a day, a team whose team level is 11 to 50 is 5 or more a day, and a team whose team level is 51 to 100 is 10 a day. If a gacha right is purchased more than once, a condition is set that the purchase price of the gacha right decreases. Alternatively, the specified number of times per unit period may be set to increase as the number of virtual users belonging to the target team increases. For example, teams with 1 to 3 virtual users belong to more than 3 times a day, teams with 4 to 10 numbers have more than 5 times a day, and teams with more than 11 numbers have more than 10 times a day. The condition is set that the purchase price of the gacha right decreases when the right is purchased.

  The process of step S2410 is executed when the target team has no purchase history of gacha right and an initial price is set as the purchase price of gacha right. Thus, when the purchase price of the gacha right is set for the target team for the first time, the price reduction condition is determined for the target virtual user. The process of step S2410 is also executed when the purchase price of the gacha right is maintained as the initial price, and when the purchase price after executing the price increase process becomes the initial price. In this way, when the initial price is reset as the purchase price of the gacha right for the target team, the price reduction condition of the target team is determined again. If the purchase price after the price increase process is not the initial price, the price reduction condition of the target team is maintained without being determined again.

  In step S2411, the price setting unit 41 refers to the purchase history data table 221B of FIG. 20 and determines the price reduction condition according to the purchase history of the gacha right by the target team. Specifically, the price reduction condition is that the higher the ratio of the number of virtual users who purchased gacha rights in the period until the number of purchases reaches the specified number in the unit period, the more the specified number of times per unit period. Set to be less.

  For example, it is assumed that this price setting process is executed when 0:00 on November 4, 20xx has passed. In the case of the team having the team ID 10001, the specified number is 5 from the price reduction condition data table 222B of FIG. From the purchase history data table 221B of FIG. 20, it can be seen that three people have purchased the gacha right in the period until reaching the prescribed number of times (5 times) on November 3, 20xx. From the team data table 212 of FIG. 19, since there are five virtual users belonging to the team with the team ID 10001, the percentage of virtual users who purchased gacha rights is 60%.

  Thus, unlike the first embodiment, after the price reduction process is executed in the second embodiment, the price reduction condition of the target team is determined again.

  In step S2412, the price setting unit 41 associates the identification information (team ID) of the target team with the price reduction condition set in step S2410 and stores it in the price reduction condition data table 222B of FIG.

  In step S2413, the price setting unit 41 associates the identification information (team ID) of the target team with the price reduction condition set in step S2411 and stores it in the price reduction condition data table 222B of FIG.

(5-2-3) Appearance Rate Setting Process Details of the appearance rate setting process in step S2304 will be described with reference to FIG. In step S2501, the appearance rate setting unit 45 executes a process (contribution determination process) for determining the team contribution to the purchase of the gacha right for the purchase user. Details of the contribution determination process will be described later.

  In step S2502, the appearance rate setting unit 45 sets the appearance rate of each virtual item based on the team contribution degree of the purchase user determined in step S2501. Specifically, the appearance rate setting unit 45 changes the appearance rate set in advance for each virtual item so that the higher the team contribution level, the higher the appearance rate of virtual items with a high degree of rarity. For example, for a virtual user with a relatively high degree of team contribution, the appearance rate of a virtual item with a rarity “5” is 30%, the appearance rate of a virtual item with a rarity “4” is 30%, and the rarity “3” For virtual users with relatively low team contribution, the virtual item with rarity “5” has an appearance rate of 10% and rarity. The appearance rate of the virtual item “4” is set to 20%, and the appearance rate of the virtual item “3” is set to 70%. If the purchase user does not contribute to the team, the appearance rate set in advance for each virtual item is used.

(5-2-4) Contribution Determination Processing Details of the contribution determination processing in step S2501 will be described with reference to FIG.

  As shown in FIG. 26, in step S2601, with reference to the purchase history data table 221B of FIG. 20, the appearance rate setting unit 45 determines that the team to which the purchase user belongs has purchased a gacha right in the most recent unit period. It is determined whether or not it has been performed more than once. That is, it is determined whether or not the purchase in step S2303 is made during the unit period immediately after the price reduction process is performed. If the purchase of the gacha right has been performed a predetermined number of times (step S2601: YES), the process proceeds to step S2602. On the other hand, if the purchase of the gacha right has not been performed a predetermined number of times (step S2601: NO), the process proceeds to step S2604.

  For example, it is assumed that this price setting process is executed when 0:00 on November 4, 20xx has passed. It is assumed that the purchase user is a virtual user with a user ID 30001. From the team data table 212 of FIG. 19, the virtual user with the user ID 30001 belongs to the team with the team ID 10001. From the price reduction condition data table 222B of FIG. 21, the prescribed number of times for the team with the team ID 10001 is five. From the purchase history data table 221B of FIG. 20, it can be seen that the team with the team ID 10001 has purchased the gacha right more than the specified number of times (5 times) on November 3, 20xx.

  In step S2602, the appearance rate setting unit 45 refers to the purchase history data table 221B in FIG. 20 and the team of the purchase user belongs for the period until the number of purchases reaches the specified number in the latest unit period. Read the purchase frequency of each virtual user.

  For example, from the purchase history data table 221B of FIG. 20, in the team with the team ID 10001, the virtual user with the user ID 30001 and the virtual user with the user ID 30056 and the user ID 30005 in the period until the specified number of times (5 times) is reached. It can be seen that the virtual user purchases the gacha right once. According to the team data table 212 of FIG. 19, two other virtual users belong to the team with the team ID 10001, but these two virtual users are in a period until they reach the specified number (5 times). I have not purchased a gacha right. That is, there are one virtual user with a purchase frequency of 60%, two virtual users with 20%, and two virtual users with 0%.

  In step S2603, the appearance rate setting unit 45 determines the team contribution degree of the purchase user based on the purchase frequency read in step S2602. The team contribution level is determined to be higher as the purchase frequency is relatively higher in the team to which the purchase user belongs.

  In step S2604, the appearance rate setting unit 45 determines that there is no team contribution to the purchase user.

(5-3) Effect In the second embodiment, when a virtual user belongs to a team, the purchase price of the gacha right varies depending on purchase history of item acquisition rights by a plurality of virtual users belonging to the team. Therefore, depending on the actual user, even if the actual user has not purchased the gacha right, if the other real user has purchased the gacha right, the amount to be paid to obtain the gacha right is reduced, and the In some cases, virtual items can be acquired. It is possible to give an opportunity to acquire a virtual item with a small amount of money to a real user who does not usually purchase the item acquisition right so that the user can purchase the gacha right. In addition, real users who have purchased a lot of gacha rights will be encouraged to purchase more gacha rights by making them realize that purchasing gacha rights will contribute to the team and demonstrating self-discovery. can do.

  In the appearance rate setting process of the second embodiment, it is possible to give an unequal feeling to a real user who has purchased a lot of gacha rights by changing the appearance rate of a virtual item with a high rarity level according to the team contribution. Absent.

  In the second embodiment, the price reduction condition is set so that the prescribed number of times per unit period increases as the team-specific attribute value increases. Usually, the team-specific attribute value increases in proportion to the time that each real user who operates each virtual user belonging to the team plays the game. That is, a team with a higher attribute value is a senior team, and a team with a lower attribute value is a beginner team. It is possible to guide the real user who operates the virtual user belonging to the beginner team to purchase the gacha right by easily setting price reduction conditions so that the prescribed number of times per unit period is reduced for the beginner team it can. By making the real user feel the pleasure of acquiring the virtual item by purchasing the gacha right, it is possible to guide the user to purchase the gacha right continuously.

  In particular, in the second embodiment, the price setting unit determines the price reduction condition as the purchase price of the gacha right is set to the initial price. That is, when the purchase price of the gacha right is maintained at the initial price, and when the purchase price of the gacha right is reduced and then returned to the initial price, the price reduction condition is determined again. As the team-specific attribute value increases, the specified number of times per unit period increases. It is possible to make a real user recognize that it is advantageous to purchase a gacha right while the prescribed number of times per unit period is set to be small, and to encourage the team to purchase the gacha right in cooperation.

  In the second embodiment, the price setting unit, as the ratio of the number of virtual users who purchased the gacha right in the period until the number of purchases reaches the specified number in the unit period, Price reduction conditions are determined so that the prescribed number of times is reduced. That is, if more real users purchase gacha rights in order to reach the specified number of purchases, the price reduction condition becomes easier. As a result, it is possible to promote the purchase of the gacha right in cooperation with the team so that the price reduction condition is changed to an easy one.
