Information on the winning probability of each item in the lottery item group (for example, the item in FIG. 2(b)) may be displayed.

In addition, when there is a past owned item, information on the past owned item may be displayed on the display unit (liquid crystal screen 330) based on the user's operation or randomly.

Further, in the above-described embodiment, one or more other items (for example, items that have not yet been possessed) may be replenished to the number equal to or less than the number of deleted items, and the lottery may be performed. Specifically, for example, in the case of user A, randomly selected items "k" and "l" are added to the two blanks in FIG. , a lottery (gacha) may be conducted based on this updated gacha management table T1. As a result, it is possible to change the information of the lottery item group in the gacha management table T1 for each user, and it is possible to give the user a sense of expectation for the gacha. Here, the item to be added may have a rarity higher than (equal to or higher than) the rarity of the deleted item.

In the above-described embodiment, the lottery target object was described as an item, but it is not limited to this. The objects may be characters (player characters and non-player characters), recovery items that can be used by characters, attack power increasing items, and the like. That is, the objects added to the gacha management table T1 are not limited to items such as weapons, armor, and costumes (items can be combined), and various other items (items can be combined) or characters (characters can be combined). and so on.

Further, for example, if the lottery in the above-described embodiment is of a type called 10 consecutive gacha, in which 10 consecutive lotteries are performed once at a time, information such as characters contained in the gacha management table T1 is required before each lottery. , and the next lottery may be drawn based on the rewritten gacha management table T1. Further, for example, even when a single-shot gacha is continuously performed instead of the 10 consecutive gacha, the next lottery may be performed using the rewritten gacha management table T1.

For example, after the first lottery based on the first gacha management table T1 is completed and before the second lottery is started, the characters possessed by the user (the (including characters obtained by lottery) is deleted, and information such as characters not possessed by the user is rewritten in the newly added gacha management table T1, and based on this rewritten gacha management table T1. A second lottery will be held. Similarly, in the third lottery, the information on the characters possessed by the user (including the characters obtained in the first and second lotteries) is deleted from the rewritten gacha management table T1, and the information owned by the user is deleted. Information such as characters not played is further rewritten in the newly added gacha management table T1, and the third lottery is conducted based on this rewritten gacha management table T1. The same may be applied to the fourth and subsequent lotteries.

Further, as described above, when the information such as characters included in the gacha management table T1 is rewritten before each lottery and then the next lottery is held, the execution of the lottery is interrupted automatically or based on the user's operation. Then, information on the probability of winning a character or the like in the next lottery may be displayed on the display unit (liquid crystal screen 330). It should be noted that it may be possible to select whether to continue or stop the lottery after the information about the winning probability of the character or the like in the next lottery is displayed.

The game described in the above embodiment is a role-playing game that includes a formation part and a battle part, but the genre of the game is not limited to this. For example, it can be applied to any game genre, whether cooperative or competitive.

Also, in the above-described embodiment, the characters that can be organized into units in the organization part are sub-characters (sub-objects), but the present invention is not limited to this. For example, all characters that can be organized into units in an organized part may be player characters (player objects), and some of these player characters may be NPCs (sub-characters (sub-objects)).

In the above embodiment, an example using a mobile terminal device as a game device is described, but the present invention is not limited to this. For example, the present invention can be implemented using arcade game cabinets provided at game arcades. Also, the present invention can be realized by using a home-use game device as the game device. Also, a system may be constructed in which each function according to the present invention is appropriately allocated to the game device and the server device. For example, the game control section may be configured in the server device, or a storage section in which each management table is stored may be configured in the game device.

Even when these other embodiments are adopted, the effects of the present invention are exhibited. Further, it is also possible to appropriately combine this embodiment with other embodiments, and other embodiments with each other.
