Description

  The present invention relates to a slot machine in which a wave is provided in the payout rate by moving back and forth between specific games having different payout rates.

In a conventional slot machine, when a special combination (for example, BB or RB) is won in a lottery of a combination, a combination of symbols corresponding to the special combination won in the game does not stop on the active line (special combination Is not won), the winning is carried over from the next game.
Furthermore, even when a special role is won, the winning stock is stocked (control is made so as not to win), and when the predetermined condition (release condition) is satisfied, the stocked special role can be won. Control is known (for example, refer to Patent Document 1).
JP 2004-290596 A (in particular, paragraphs “0061” to “0065”)

  However, in the above-mentioned conventional technology, unless the predetermined condition is satisfied, it is controlled that the winning special role is not won (stocking the special role), even though the player has been won. Since the player cannot win, there is a tendency that it is not preferable.

  Therefore, the problem to be solved by the present invention is to make it easy to carry a winning combination after the next game and to give a player a sense of expectation over a plurality of games.

The present invention solves the above-described problems by the following means.
The invention of claim 1 comprises a role lottery table that determines the winning probability of each role, and a role lottery means for drawing a role using the role lottery table, and the role lottery table has a predetermined payout rate. A first specific combination for shifting to a first specific game set to a value, a second specific combination for shifting to a second specific game for which the play rate is set to a value lower than the predetermined value, and a player The first role lottery table that determines the winning probability of each role including the replay that causes the replay to be performed, the winning probability of each role including the replay is determined, and the winning probability of the replay is determined as the first probability. A second combination lottery table set higher than the combination lottery table, and when the first specific combination or the second specific combination is won during the game using the first combination lottery table, The first specified role or the second specified role won Until the first specific combination or the second specific combination is won by the combination lottery means and the first specific combination or the second specific combination is won by the combination lottery means. In the game until winning a prize, the winning of the first specific combination or the second specific combination is controlled to be carried over after the next game. In the first combination lottery table, the first specific combination and the second specific combination are controlled. The winning area of the combination is set in the overlapping winning area with the replay, respectively, and when the first specific combination or the second specific combination and the replay are won, or the first specific combination or the When the replay is won when the second specific combination is being carried over, the replay winning is given priority.

  According to a second aspect of the present invention, in the slot machine according to the first aspect, each of the first specific game and the second specific game is a game in which a payout rate is set to exceed 1. Features.

  According to a third aspect of the present invention, in the slot machine according to the first aspect, the first specific game is a game in which a payout rate is set to exceed 1, and the second specific game is a payout rate Is a game set to be less than 1.

  According to a fourth aspect of the present invention, in the slot machine according to any one of the first to third aspects, the first specific game is a combination except for a small combination that pays out a predetermined number of game media when winning. The game is characterized in that the game is performed until the number of game media payout reaches a predetermined number by controlling the small role so that a winning combination can be won.

  The invention of claim 5 is the slot machine according to any one of claims 1 to 4, wherein the first specified combination or the second specified combination and the replay are won, or When the replay is won when the winning of the first specific combination or the second specific combination is carried over, the control is performed so that the selected replay is always won, and the first specific combination or the second specific combination is controlled. In a game in which a winning combination is being carried out and a game that has not been won in the replay, the first specific winning combination or the second specific winning combination that has been won is always controlled to win. And

  According to a sixth aspect of the present invention, in the slot machine according to any one of the first to fifth aspects, the winning of the first specific combination is carried over during a game using the second combination lottery table. It controls to output the effect of whether or not.

(Function)
In the above invention, in a game in which the first combination lottery table is used, a lottery of the combination including the first specific combination and the second specific combination is performed, and either the first specific combination or the second specific combination is won. Until the winning first specific combination or second specific combination wins, the game moves to the game using the second combination lottery table. Here, since the 1st specified combination and the 2nd specified combination are roles that carry over the winning after the next game unless a prize is won, during the game using the 2nd combination lottery table, Unless the specific combination wins, the winning of the first specific combination or the second specific combination won is carried over. Further, in the game using the second combination lottery table, the probability of winning the replay is higher than in the game using the first combination lottery table.

  In the game won for replay, the winning of replay is given priority over the first specified combination or the second specified combination carrying over the winning, so in the game, the first specified combination or the second specified combination is won It becomes difficult to do. Therefore, in the game using the second combination lottery table, it becomes easy to win a replay, and the first specific combination or the second specific combination is difficult to win. And when the 1st specific combination or the 2nd specific combination which is carrying over a win wins, it will transfer to either one of the 1st specific game or the 2nd specific game with which a payout rate differs.

  In the following embodiments, the first specific combination corresponds to BB or MB2, and the second specific combination corresponds to MB1. The first combination lottery table corresponds to the combination lottery table 62A, and the second combination lottery table corresponds to the combination lottery table 62B.

  According to the present invention, when the first specific combination or the second specific combination is won, the game shifts to a game in which the winning probability of replay is increased, and the first specific combination or the second specific combination is carried over during the game period. There will be more opportunities to be Thereby, the game which carried over the winning of a 1st specific combination or a 2nd specific combination can be continued.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an outline of control of the slot machine 10 in the present embodiment.
(Game control means)
The game control means 60 of the slot machine 10 is a means for overall control of the entire slot machine 10 including the progress and effects of the game of the slot machine 10, and the lottery of the role, the drive (rotation and stop) control of the reel 31, and It controls the progress of games such as payout at the time of winning a prize, the output of effects, the notification of information, and the like. The game control means 60 is provided on a predetermined control board. The game control means 60 is a CPU for performing calculations, a ROM for storing programs necessary for the progress of games, data for production, etc. A RAM or the like for temporarily storing captured data or the like when performing control.

(Start switch, stop switch, bet switch)
As shown in FIG. 1, a bet switch 40, a start switch 41, and a stop switch 42 are electrically connected to the input side (left side in FIG. 1) of the game control means 60.
The bet switch 40 is a switch that is operated when a player inserts a stored medal, and is a switch that sets an effective line by the operation. Although the medal insertion slot is not shown in FIG. 1, the medal insertion slot is a part for inserting an actual medal for setting an effective line, like the bet switch 40. The insertion of medals is included in the operation of the bet switch 40.

The start switch 41 is a switch operated by the player when starting the reel 31.
Furthermore, three stop switches 42 are provided corresponding to the three reels 31 and are operated by the player when stopping the corresponding reels 31.

(Motor, reel)
Peripheral devices such as the motor 32 described below are electrically connected to the output side (right side in FIG. 1) of the game control means 60.
The motor 32 is for rotating the reel 31, is connected to the center of rotation of the reel 31, and is controlled by the game control means 60.
The reel 31 has a ring shape, and a reel tape on which a plurality of types of symbols (such as symbols constituting a role to be described later) is printed is attached to the outer peripheral surface thereof.

  In the present embodiment, three reels 31 are provided in parallel. Each reel 31 is arranged so that three symbols that are continuous in the vertical direction can be seen from a display window (not shown) provided on the front panel of the slot machine 10. Therefore, nine symbols are arranged so that a total of nine symbols can be seen from the display window of the slot machine 10.

  When the start switch 41 is operated, a signal generated at that time is input to the game control means 60. When the game control means 60 (specifically, the reel control means 64 described later) receives this signal, it controls to drive all the motors 32 and rotate all the reels 31. As the reel 31 is rotated by the motor 32 in this way, the symbols on the reel 31 are moved and displayed in the vertical direction in the display window at a predetermined speed.

  When the stop switch 42 is operated, a signal generated at that time is input to the game control means 60. When the game control means 60 (specifically, the reel control means 64 described later) receives this signal, it controls the drive of the motor 32 corresponding to the stop switch 42 and controls the stop of the reel 31 related to the motor 32. I do.

  Here, in the present embodiment, the reel 31 is provided with left, middle, and right three, and the stop switch 42 is provided with left, middle, and right three correspondingly. That is, the reel 31 corresponding to the left stop switch 42 is the left reel 31, the reel 31 corresponding to the middle stop switch 42 is the middle reel 31, and the reel 31 corresponding to the right stop switch 42 is the right reel 31.

(Production output devices (lamps, speakers, image display devices))
In addition, on the output side (right side in FIG. 1) of the game control means 60, effect output devices such as the lamp 21, the speaker 22, and the image display device 23 are electrically connected.
The lamps 21 are effects lamps for the slot machine 10 and are turned on in a predetermined pattern when predetermined conditions are satisfied. The lamp 21 includes a back lamp (not shown) fixed to the inner peripheral side of each reel 31, an upper lamp and a side lamp that are arranged on the front surface of the housing of the slot machine 10 and blink when a winning combination is made. A lamp (not shown) and the like are included.

Furthermore, the speaker 22 outputs a predetermined sound when a predetermined condition is satisfied so as to perform various effects during the game.
Furthermore, the image display device 23 is composed of a liquid crystal image display device, a dot display, or the like, and displays various effect images, predetermined information, and the like during the game.

  At the start of the game, the player operates the bet switch 40 to insert medals and turns on the start switch 41. When the start switch 41 is turned on, the number of effective lines is determined and all the reels 31 are started (rotation is started).

  Then, the player presses each stop switch 42 to stop the rotation of each reel 31. When all the reels 31 are stopped, when the combination of symbols corresponding to any of the winning combinations stops on the active line and the winning combination of the winning combination is made, a medal corresponding to the winning combination is paid out.

(Design combination line, effective line)
Although not shown, a symbol combination line (effective line) is provided in a portion including the display window of the slot machine 10.
Here, the “symbol combination line” is a line of symbols when the reel 31 is stopped, and is a line that forms a combination of symbols. In the present embodiment, it is composed of a total of five lines: lines provided respectively in the middle, upper, and lower stages in the horizontal direction, and diagonal lines in the downward and leftward diagonal directions. The three symbols that are continuous above and below each reel 31 are positioned on one or more symbol combination lines.

Further, among the five symbol combination lines, an effective line and an invalid line are set from the symbol combination lines according to the number of medals inserted by the player.
Here, in the present embodiment, the “effective line” is a line for winning a combination when a combination of symbols corresponding to any combination stops on the line.

  On the other hand, an “invalid line” occurs when the number of inserted medals is other than three, and is a line that is not set as an effective line among the symbol combination lines, and a combination of symbols corresponding to any combination is that line. Even if it stops, the profit is not given according to the combination (medal payout etc.). In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

  In this embodiment, the number of medals inserted in one game is one, two, or three. When the number of medals inserted is 1, the horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbol combination lines are set as invalid lines. When the number of inserted medals is 2, the horizontal, upper and lower symbol combination lines (three in total) are set as valid lines, and the other two symbol combination lines are set as invalid lines. Is done. Furthermore, when the number of inserted medals is 3, all the symbol combination lines (a total of 5) are set as valid lines and there are no invalid lines.

(Role)
FIG. 2 is a diagram showing types of winning combinations (combinations to be drawn by the winning lottery means 61 described later), winning probabilities, the number of payouts, and end conditions in the first embodiment.
As shown in FIG. 2, special roles (BB, MB1, MB2, RB, and CB) and small roles (small role 1, small role 2, small role 3, small role 4, and replay) are provided. It has been.

  The special role is shifted from a normal game to a special game (a game in which a lottery of a role different from the normal game is performed and a medal can be expected more than the normal game, which is advantageous to the player). It is a role. In the first embodiment, as shown in FIG. 2, BB (Big Bonus), MB (Middle Bonus), RB (Regular Bonus) and CB (Challenge Bonus) are provided as special roles.

Here, BB is a role that shifts to a BB game that is one of special games, and MB (MB1 or MB2) is a role that shifts to an MB (MB1 or MB2) game that is another one of special games. RB is a role for shifting to the RB game which is still another one of the special games, and CB is a role for shifting to the CB game which is another one of the special games.
During the BB game (in the special game state described later, the same applies hereinafter) and during the RB game, the game is won / winned with the small role 4 with a high probability (described later). As shown in FIG. 2, the BB game end condition is set to 345 medals paid out during the BB game, and the RB game end condition is that the winning combination is 8 times or It is set that 12 games have been continued.

Furthermore, two types of MB (MB1 and MB2) are provided in this embodiment, and these differ only in the end conditions. As shown in FIG. 2, the end condition of the MB1 game is set to be 29 medals paid out during the MB1 game. In the MB2 game, the end condition is 253 during the MB2 game. It is set that there was a payout.
In addition, during the CB game, it is a game that is controlled so that a small role can be won according to the skill of the player. If CB is won during the MB1 game, only the next game (1 game) becomes the CB game. On the other hand, during the MB2 game, the CB game is continuously executed every game until the above end condition is satisfied.

The small role (excluding replay) is a role in which a predetermined number of medals are paid out. In this embodiment, the small role 1, the small role 2 and the small role 3 are used as the small roles in the normal game. In addition to the above small roles, a small role 4 is further provided as a small role during the BB game and the RB game. The combination of symbols corresponding to the combination and the number of medals to be paid out are set differently according to the type of the combination.
Furthermore, the replay of the small combinations is a re-playing role that allows the re-playing while maintaining the number of medals inserted in the game.

In each of the above combinations, if the combination of symbols corresponding to the combination does not stop on the active line in the game selected for the combination, a combination that is carried over after the next game and a combination that is not carried over are determined. .
As a carry-over, there is a special role other than CB (refers to BB, RB, MB1 or MB2; hereinafter referred to as “specific special role”). When a special special combination is won, the reels 31 are controlled to carry over the special special combination after the next game until the combination of symbols corresponding to the specific special combination stops on the active line when the reel 31 is stopped. The

  A game in which a special special role is not won (a game in which a special special role is not carried over) is referred to as “non-inside”. In addition, the special combination that can carry over the winning in the game or the game before that is won, but the combination of symbols corresponding to the selected special combination has not stopped on the active line (no winning) During a game (a game in which the winning of a special special role is carried over) is called “inside”.

  As described above, the winning of the special special role is carried over, while the non-special special role is not carried over. When a role other than a specified special role is won in a lottery of a role, the winning role is valid only in the game, and the winning is not carried over after the next game. In other words, in the game where these winning combinations are won, the reel 31 is controlled to stop so that the combination of symbols corresponding to the winning combination can be stopped (winning) on the active line. Regardless, at the end of the game, the right to the winning role will cease.

  In addition, as shown in FIG. 2, combinations of symbols of the reel 31 corresponding to the various types of roles described above are determined in advance. When all the reels 31 are stopped, the combination of symbols corresponding to any of the combinations stops on the active line, and when the winning combination of the combination is won, the number of medals corresponding to the combination is paid out.

The game control means 60 includes the following part lottery means 61 and the like. The following means in the present embodiment are examples, and the game control means 60 is not limited to the means shown in the present embodiment.
(Role lottery means)
The role lottery means 61 performs lottery for a role (the special role and the small role described above). The role lottery means 61 is based on, for example, a random number generator for hardware lottery (hardware random number, etc.), a random number extractor for extracting random numbers generated by the random number generator, and a random number value extracted by the random number extractor. And determining means for determining the presence / absence of a winning combination and the winning combination.

  The random number generation means generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). The random number is, for example, a random number for which the counter that performs 1 count at 200 n (nano) sec continues to count as a cycle in the range of 0 to 65535, and continues to count the random number while the slot machine 10 is powered on. .

  The random number extracting means extracts the random number generated by the random number generating means at a predetermined time, in this embodiment, when the start switch 41 is turned on by the player. The determination unit determines the combination corresponding to the region to which the random number value belongs by comparing the random number value extracted by the random number extraction unit with a combination lottery table 62 described later. For example, when the extracted random number value belongs to the BB winning area, it is determined that the BB is winning, and when it belongs to the non-winning area, it is determined not to win.

(Role drawing table)
The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. In addition, the role lottery table 62 includes a game state (in normal game (non-internal / internal, non-RT game / RT game), BB game, RB game, MB1 game, MB2 game, CB game. Each medium) has a unique combination lottery table 62.

  FIG. 3 is a diagram showing these combination lottery tables 62. In FIG. 3, a combination lottery table 62A is a combination lottery table 62 used in a non-internal and non-RT game of a normal game, and a combination lottery table 62B is in an RT game of a normal game and is MB1 or MB2. This is the role lottery table 62 used after (inside) the winner. The role lottery table 62C is a role lottery table 62 that is used during a non-RT game and inside of a normal game.

Furthermore, the role lottery table 62D is a role lottery table 62 used during the MB1 game (including the time of the CB game during the MB1 game), and the role lottery table 62E is used during the MB2 game (in the CB game). It is a role lottery table 62. Furthermore, the combination lottery table 62F is a combination lottery table 62 used during the BB game and the RB game.
Each combination lottery table 62 has a predetermined range of lottery areas. The lottery area is divided into a winning area and a non-winning area for each combination, and the winning combinations are determined in advance. It is set to a predetermined ratio so as to be a probability.

  In the present embodiment, the winning area for the combination includes a single winning area and an overlapping winning area. For example, in FIG. 3, in the combination lottery table 62A, only the single winning area is provided as the winning area for the small combination 2, the small combination 3, and the RB. The winning area of the small role 1 is set as an overlapping winning area with the BB in addition to the single winning area. Furthermore, the winning area of BB is set as an overlapping winning area with replay in addition to the single winning area. Furthermore, the winning areas of MB1 and MB2 are all set as overlapping winning areas with replay.

  Further, in the combination lottery table 62B (in the RT game), it is set so that the winning areas of RB, BB, MB1 and MB2 do not exist as compared with the combination lottery table 62A. That is, the single winning area of RB and BB in the winning lottery table 62A is set as a non-winning area in the winning lottery table 62B. Furthermore, the overlapping winning area for BB and small role 1 and the overlapping winning area for BB and replay in the winning lottery table 62A are set as the single winning area for small role 1 and replay, respectively. In addition, the overlapping winning area for MB1 and MB2 and replay is set as the single winning area for replay. Furthermore, the winning lottery table 62B has a smaller non-winning area than the winning lottery table 62A, and accordingly, the winning probability of replay is set higher (1 / 1.2).

Furthermore, in the combination lottery table 62C, the winning area for replay is set in the same area as the combination lottery table 62A with respect to the combination lottery table 62B, and the rest is the same as the combination lottery table 62B.
Furthermore, the combination lottery table 62D is set so that the winning regions of BB, MB1, and MB2 do not exist with respect to the combination lottery table 62A. Further, the winning area of CB is 1/65536 in the role lottery table 62A, whereas it is set to 1/4 in the role lottery table 62D.
Further, in the combination lottery table 62E, the winning area for replay and CB is set as a non-winning area with respect to the combination lottery table 62D.
Furthermore, the combination lottery table 62F is set so that the small combination 1 to the small combination 4 are selected and the small combination 4 is won with high probability (1 / 1.2).

  In each winning lottery table 62, a winning area and a non-winning area for each winning combination are determined for each number of inserted medals (1 to 3), although not shown. Furthermore, the winning area and the non-winning area of each role are determined for each set value of the payout rate (for example, 6 levels from setting 1 to setting 6), and the winning probability of each role shown in FIG. This is an example of the winning probability of a combination corresponding to the set value of the number of inserted medals and the payout rate of one (three in FIG. 3).

  If a winning combination MB1 or MB2 is won during a game in which the role lottery table 62A is used (in a non-internal and non-RT game of a normal game), the winning MB1 or MB2 wins after the next game. Up to this point, the game in which the combination lottery table 62B is used (the RT game inside) is used. In addition, if BB or RB is won during a game in which the role lottery table 62A is used, a game (internal non-RT game) in which the role lottery table 62C is used after the next game.

Furthermore, in a game in which the role lottery table 62A is used, in the MB1 game, or in the next game where CB is won during the MB1 game, the game in which the role lottery table 62D is used (CB game).
Further, during the MB2 game, the game using the combination lottery table 62E is used. All MB2 games are CB games.
Further, when a BB or RB wins and the next game or later is shifted to a BB game or an RB game, the role lottery table 62F is used during the BB game or the RB game.

(Special role selection carryover means, special role flag)
The special combination winning carry-over means 63 stops the combination of symbols corresponding to the specific special combination at the effective line when the above-mentioned specific special combination (BB, RB, MB1 or MB2, excluding CB) is won. In the game until it is done (until the specific special combination wins), the winning of the specific special combination is controlled to be carried over after the next game.

  In this embodiment, when the special special combination is won, the special special combination flag (BB, RB, MB1 or MB2 flag) 63a is set for each type of the special special combination in order to store the special special combination. Prepare. For example, when BB is won, the BB flag 63a is turned on (from OFF), and when RB is won, the RB flag 63a is turned on. Similarly, when MB1 is won, the MB1 flag 63a is turned on, and when MB2 is won, the MB2 flag 63a is turned on. The ON state of each flag 63a is maintained until the specific special combination wins, and when the specific special combination wins, the flag 63a is returned from ON to OFF.

(Reel control means)
First, the reel control means 64 controls to start rotation of all (three) reels 31 when the start switch 41 is operated. Further, the reel control means 64 determines the stop position to be described later based on the winning lottery result by the winning lottery means 61 when the stop switch 42 is operated, the timing when the stop switch 42 is operated, and the like. With reference to the table 65, the stop position of the reel 31 corresponding to the stop switch 42 is determined, and the motor 32 is driven and controlled so that the reel 31 stops at the determined position.

  For example, the reel control means 64 controls to stop the reel 31 so that the combination of symbols corresponding to the winning combination is stopped on the effective line within the range of the stop control of the reel 31 in the game won for the winning combination. The reel 31 is controlled to stop so that a combination of symbols corresponding to a combination other than the combination is not stopped on the effective line.

  Here, “within the range of stop control of the reel 31” means within the range of the amount of rotation of the reel 31 (the number of movements of the symbol) from the moment when the stop switch 42 is operated until the reel 31 actually stops. In this embodiment, except for the CB game (including the MB2 game), it is set within 5 symbols including the symbol at the moment when the stop switch 42 is operated. In other words, it means the stop control time range of the reel 31, that is, the time from the moment when the stop switch 42 is operated until the reel 31 actually stops. In this embodiment, the moment when the stop switch 42 is operated. Within 190 ms.

  Thus, any of the symbols up to the number of symbols (5 symbols) within the range of stop control of the reel 31 counted from the symbol at the moment when the operation of the stop switch 42 is detected is a symbol to be stopped on the effective line. When the stop switch 42 is operated, the symbol is controlled to stop at the active line.

  In other words, when the reel 31 is stopped immediately at the moment when the stop switch 42 is operated at the time of winning the winning combination, if the symbol related to the winning winning combination does not stop on the effective line, By controlling the rotational movement of the reel 31 within the “range of control”, the symbol related to the winning combination is controlled to stop as much as possible on the effective line.

  On the contrary, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated when the winning combination is not won, the combination of symbols corresponding to the winning combination is stopped on the effective line. When the reel 31 is stopped, the reel 31 is controlled to rotate and move within the “reel 31 stop control range” so that the symbol combination corresponding to the winning combination is not stopped on the active line.

In addition, in the CB game, “within the range of stop control of the reel 31” in the left reel 31 is a symbol that is controlled to move by one symbol from the symbol when the stop switch 42 is operated (moment), or a stop switch. The stop control time from when 42 is operated (instant) until the reel 31 is stopped is within 75 ms.
Furthermore, “within the range of stop control of the reel 31” in the middle reel 31 and the right reel 31 during the CB game is the same as the game other than the CB game.

(Stop position determination table 65)
The stop position determination table 65 determines the stop position of the symbol of the reel 31 from the lottery result of the combination by the combination lottery means 61 and the position of the reel 31 at the moment when the stop switch 42 is operated.
The following types are provided as the stop position determination table 65.
(1) BB table (used in a game in which a BB is won alone or a game in which a BB win is being carried over and a role is not won)
(2) RB table (used in a game in which an RB is won or a game in which a RB win is being carried over and a role is not won)
(3) MB1 table (used in a game in which a winning of MB1 is being carried over and a winning combination is not played)

(23) CB gaming table (used during CB gaming (including MB2 gaming))
(24) Non-winning table (used in a game when a non-winning role has not been carried over to a special role)

The BB table is used on the condition that the BB is won alone in the game, or the BB is won in the game before the game and is not won in the game, and within the range of the stop control of the reel 31 The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to BB is stopped on the effective line and the combination of symbols corresponding to the role other than BB is not stopped on the effective line.
The RB table is used on condition that the RB is won in the game, or the RB is won in the game before the game and is not won in the game. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to is stopped on the effective line and the combination of symbols corresponding to roles other than RB is not stopped on the effective line.
The MB1 table is used on condition that MB1 is won in the game before the game and is not won in the game, and the combination of symbols corresponding to MB1 within the range of the stop control of the reel 31 is used as an effective line. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to roles other than MB1 is not stopped on the effective line.
The same applies to the MB2 table.

In addition, the CB table is used on condition that the CB is won in the game, and the combination of symbols corresponding to the CB is stopped on the effective line within the range of the stop control of the reel 31 and corresponds to a role other than the CB. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols to be stopped is not stopped on the effective line.
The same applies to the small role 4 table.

The small role 1 table is used when the small role 1 is elected alone and when the small role 1 is won in a game that does not carry over the special role, and corresponds to the small role 1 within the range of stop control of the reel 31. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols is stopped on the effective line and the combination of symbols corresponding to the role other than the small role 1 is not stopped on the effective line.
The small role 2 table is used at the time of winning the small role 2 and when winning the small role 2 in a game that does not carry over the special role, and corresponds to the small role 2 within the range of stop control of the reel 31. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the combination other than the small combination 2 is not stopped on the effective line.
The same applies to the small role 3 table.

  In addition, the non-winning table is used in a non-winning game that does not carry over the winning of the special role, and the symbol when the reel 31 is stopped so that the combination of symbols corresponding to any of the combinations does not stop on the active line. Are defined.

  Furthermore, the BB priority BB-pocket 1 table is used when the BB and the small role 1 are overlapped, and the reel 31 that stops first and second has both the symbols related to BB and the small role 1. As long as the reel 31 is controlled to stop at any one of the effective lines and stops third, priority is given to first stopping the combination of symbols corresponding to the BB on the effective line, and the symbol corresponding to the BB. If the combination cannot be stopped on the effective line, the combination of symbols corresponding to the small role 1 is determined to be stopped on the effective line.

  More specifically, when the BB priority BB-pocket 1 table is used, in the reel 31 that stops first, both the BB and the symbols relating to the small role 1 are set to any effective line as much as possible. Control to stop. If both the symbols related to BB and the small combination 1 cannot be stopped on the effective line, control is then performed so that the symbols related to BB are stopped on the effective line. Further, when the symbol related to BB cannot be stopped on the active line, control is then performed so that the symbol related to the small role 1 is stopped on the active line.

  Also, when the first reel 31 is stopped, when both the symbols related to BB and the small hand 1 are stopped on the active line, when the second reel 31 is stopped, it is related to the BB and the small hand 1 Control is performed so that both symbols are tempered (the symbols related to the BB of the two reels 31 are aligned on the same effective line, and the symbols related to the small combination 1 of the two reels 31 are aligned on the same effective line). If both the symbols related to BB and the small combination 1 cannot be tempered, then control is performed so that only the symbol related to BB is tempered. Further, when the symbol related to BB cannot be made into a template, next, control is performed so that the symbol related to the small role 1 is made into a template.

Furthermore, when the first reel 31 is stopped and only the symbol related to BB is stopped on the active line, the reel related to the symbol related to BB is tempered when the second reel 31 is stopped. 31 is controlled to stop. The third reel 31 is also controlled so as to stop at the effective line where the symbol related to BB is tempered.
On the other hand, when the first reel 31 is stopped, if only the symbol related to the small part 1 is stopped on the active line, the symbol related to the small part 1 will be tempered when the second reel 31 is stopped. Then, the reel 31 is controlled to stop. The third reel 31 is also controlled so as to stop at the effective line where the symbol related to the small part 1 is tempered.

  Furthermore, when the second reel 31 is stopped, when both the symbols related to BB and the small part 1 are tempered, when the third reel 31 is stopped, first, the symbol related to BB is first tempered. Control to stop the line. Then, if the symbol related to BB cannot be stopped on the activated line that has been tempered, then the control relating to the small role 1 is controlled to be stopped on the emptied effective line.

When the second reel 31 is stopped and only the symbol related to BB is tempered, when the third reel 31 is stopped, the symbol related to BB is stopped at its effective line (BB The reel 31 is controlled to stop.
On the other hand, when the second reel 31 is stopped and only the symbol related to the small part 1 is tempered, when the third reel 31 is stopped, the symbol related to the small part 1 is stopped on the effective line. As described above (so that the small combination 1 wins), the reel 31 is controlled to stop.
Furthermore, when neither the BB nor the small role 1 can be stopped on the active line (which is tempered) when the third reel 31 is stopped, the combination of symbols corresponding to any of the combinations is also effective. The reel 31 is controlled to stop so as not to stop.

The above is

MB1 priority MB1-small role 2 table,
MB1 priority MB1-small role 3 table,
MB2 priority MB2-small role 1 table,
MB2 priority MB2-small role 2 table,
The same applies to the MB2 priority MB2-small role 3 table.
That is, in the BB priority BB-small role 2 table, the small role 1 is replaced with the small role 2 in the above contents.
The BB priority BB-small combination 3 table is obtained by replacing small combination 1 with small combination 3 in the above contents.

In the replay priority BB-replay table, among the above contents, BB is replaced with replay, and the small combination 1 is replaced with BB.
In the replay priority MB1-replay table, among the above contents, BB is replaced with replay, and a small combination 1 is replaced with MB1.
In the replay priority MB2-replay table, among the above contents, BB is read as replay, and a small combination 1 is read as MB2.

Furthermore, the MB1 priority MB1-small role 1 table is obtained by replacing BB with MB1 in the above contents.
In the MB1 priority MB1-small role 2 table, BB is replaced with MB1 in the above contents, and small role 1 is replaced with small role 2.
In the MB1 priority MB1-small role 3 table, BB is replaced with MB1 in the above contents, and small role 1 is replaced with small role 3.

Furthermore, the MB2 priority MB2-small role 1 table is obtained by replacing BB with MB2 in the above contents.
In the MB2 priority MB2-small role 2 table, BB is replaced with MB2 in the above contents, and small role 1 is replaced with small role 2.
In the MB2 priority MB2-small role 3 table, BB is replaced with MB2 in the above contents, and small role 1 is replaced with small role 3.

Here, the symbol arrangement of each reel 31 will be described.
FIG. 4 is a plan view showing a symbol arrangement on the outer peripheral surface of each reel 31 in the present embodiment. FIG. 4 shows only a part of the symbol arrangement, and a predetermined symbol is also displayed in a blank part in the drawing, but the description is omitted here. As shown in FIG. 4, all the symbols of “RP”, which are symbols related to replay, are arranged at intervals of 5 symbols or less on each reel 31. Therefore, symbols of “RP” are arranged on the reel 31 at intervals within the range of the stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). Thereby, at the time of winning the replay, it can be controlled to always stop the winning combination of replay symbols on the active line regardless of the position of the reel 31 at the moment when the stop switch 42 is operated.

  Therefore, in this embodiment, when the replay priority BB-replay table, the replay priority MB1-replay table, and the replay priority MB2-replay table are used, the replay winning is given priority, but the replay can always be won. In reality, only replay wins and BB, MB1 and MB2 do not win.

Further, although not shown in FIG. 4, like the “RP” symbol, all the “bell” symbols are arranged within an interval of five symbols or less. Accordingly, symbols of “bell” are arranged on the reel 31 at intervals within the range of the stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). As a result, the “bell” symbol can always be stopped on the effective line regardless of the position of the reel 31 at the moment when the stop switch 42 is operated. Therefore, when winning the small combination 2, it is always possible to stop the combination of symbols corresponding to the small combination 2 “bell”-“bell”-“bell” on the active line.
In addition, for MB1, MB2, CB and the small part 4 configured by a combination of symbols of “bell” and “RP”, the reel 31 at the moment when the stop switch 42 is operated is always in any position. It is possible to stop the combination of symbols corresponding to MB1, MB2, CB and the small part 4 on the effective line.

  Therefore, in this embodiment, MB1 priority MB1-small role 1 table, MB1 priority MB1-small role 2 table, MB1 priority MB1-small role 3 table, MB2 priority MB2-small role 1 table, MB2 priority MB2-small role 2 When the table, MB2 priority MB2-small role 3 table is used, the winning of MB1 or MB2 is given priority, but since MB1 or MB2 can always win, only MB1 or MB2 actually wins, There is no case where small roles 1 to 3 win a prize.

  Further, the CB gaming table is used during CB gaming, and within the range of stop control of the reel 31 during CB gaming for the small roles 1 to 3 (the moment the stop switch 42 is operated for the left reel 31). Within the next symbol (within 75 ms) and within 5 symbols (within 190 ms) for the middle reel 31 and the right reel 31, the combination of symbols corresponding to the small roles 1 to 3 is stopped on the active line. The combination of symbols when the reel 31 is stopped is determined as possible.

Here, in this embodiment, among the small combinations 1 to 3, the small combination having the largest payout number is the small combination 2. And the combination of the symbols corresponding to the small role 2 is “bell”-“bell”-“bell” as shown in FIG.
As a result, during the CB game, for the left reel 31, if the stop switch 42 is operated so that the “bell” symbol stops on the active line, the “bell” symbol is displayed on any active line. Can be stopped. For the middle reel 31 and the right reel 31, regardless of the position of the stop switch 42, the symbol “bell” can be stopped on the effective line, and the winning of the small combination 1 can be obtained.
Using the stop position determination table 65 described above, the reel control means 64 controls to stop the reel 31 within the range of stop control of the reel 31.

The CB game is provided with a CB game that is played in the next game after the CB wins and wins during the MB1 game, and a CB game that is continuously played during the MB2 game.
In the former CB game, a role lottery table 62D is used to draw a role, and in the latter CB game, a role lottery table 62E is used to draw a role. As a result, during the CB game, there is an opportunity to win a small combination 1 to a small combination 3, RB, replay (only the former) and CB (only the former). When the RB is won, the MB1 game or the MB2 game is ended at that time, and the subsequent game shifts to a game in the normal game (a game in which the role lottery table 62C is used). In addition, when the replay is won, the replay won is given priority over the small role, so the replay table is used in the game. Furthermore, when a CB is won, the CB winning is given priority, so the CB table is used in the game. Furthermore, when the small combination 1 to the small combination 3 is won, the CB gaming table is used in the game as described above.

(Stop symbol judging means)
The stop symbol determination means 66 determines whether or not the symbol combination of the reel 31 stopped on the effective line matches the symbol combination corresponding to any combination when the reel 31 is stopped. The stop symbol determination means 66 determines a symbol on the effective line by detecting, for example, an angle or the number of steps when the motor 32 is stopped.

  The stop symbol determining means 66 does not determine the symbol combination after the reels 31 actually stop, but the reels are determined by the stop position determination table 65 from the position of the reels 31 at the moment when the stop switch 42 is operated. It is also possible to determine the combination of symbols on the active line when 31 stop positions are determined.

(Payment means)
The payout means 67 is determined by the stop symbol determination means 66 that the combination of symbols stopped on the active line when the reel 31 is stopped matches the symbol combination corresponding to one of the combinations, and when the winning combination is won In addition, a predetermined number of medals are paid out to the player in accordance with the winning combination, or processing such as credit addition is performed. Further, at the time of replay winning, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

(Special game control means)
The special game control means 68 starts the special game (BB game, RB game, MB1 game, MB2 game or CB game) (transition from the normal game to the special game), the progress of the game during the special game, and the special game This controls the end (shift from special game to normal game) and the like.

  The special game control means 68 shifts from the normal game to the BB game when the combination of specific symbols corresponding to BB stops on the active line. Further, when the combination of specific symbols corresponding to RB stops on the active line, the game is shifted from the normal game to the RB game. Furthermore, when a specific symbol combination corresponding to MB1 or MB2 stops on the active line, the normal game is shifted to the MB1 game or MB2 game, respectively. Furthermore, when the combination of specific symbols corresponding to CB stops on the active line, the CB game is entered.

The special game control means 68 includes a special game state flag 68a. The special game state flag 68a is a flag that is turned on when the game state is set to the special game state during the BB game, and turned off when the special game state ends.
During a normal game, when the symbol combination corresponding to BB stops on the active line, BB is won and the BB game is started from the next game.

  At this time, the special game control means 68 turns on the special game state flag 68a immediately before the start of the first game of the BB game (immediately before the reception of medals from the player). Thereby, the special game state is set from the first game of the BB game.

Furthermore, the special game control means 68 continues to determine whether or not the special game state end condition is satisfied. In the present embodiment, the special game state end condition is when at least one of the case where the number of winning a winning combination reaches 8 times or the case where the number of games reaches 12 times is satisfied.
Then, when the number of winning a winning combination reaches 8 times, or when the number of games in the special gaming state reaches 12, the special game control means 68 terminates the game to end the special gaming state. Sometimes, the special gaming state flag 68a is turned off.

  Furthermore, the special game control means 68 turns on the special game state flag 68a immediately before the start of the next game of the game (immediately before the reception of medals from the player). Thus, in a game that satisfies the special game state end condition, the special game state ends at the end of the game, but the game state is set to the special game state again immediately before the start of the next game.

Note that the BB game of the present embodiment is as described above, but may be a BB game that has been conventionally known.
That is, when shifting to the BB game, first, as in the normal game, a general game for playing a game by inserting medals within a predetermined number (for example, 3) is performed, and a transition role for shifting to a bonus game in this general game is performed. The lottery is performed. When the transition role is won and won during the general game, the next game is shifted to the bonus game.

  In the bonus game, one medal is inserted and a game is performed in which one symbol combination line in the middle in the horizontal direction is set as an effective line. In the bonus game, the lottery of the predetermined role described above is performed, and when the number of winning of the predetermined role or the number of games of the bonus game reaches a specified number, the bonus game is ended and the game returns to the general game. In this way, the general game and the bonus game are satisfied until the BB game end condition (for example, when the number of games of the general game reaches the specified number of times or when the number of times of transition to the bonus game reaches the specified number of times). It will repeat the journey to and from.

In the present embodiment, the BB game end condition is set such that the number of medals paid out during the BB game exceeds the upper limit. Here, the upper limit value of the present embodiment is set to 345 sheets.
Therefore, in this embodiment, the special game control means 68 counts the number of medals paid out during the BB game, and keeps updating the number of coins paid out for each game.
When the special game control means 68 determines that the counted number of payouts exceeds the upper limit (exceeds 345), the special game control means 68 determines that the end condition of the BB game is satisfied, and the normal game after the next game. Control to return to.

  Furthermore, the special game control means 68 controls to shift to the RB game on condition that the combination of symbols corresponding to the RB has stopped on the active line, that is, the RB has won a prize. The RB game is a game that is executed when the number of winning a winning combination reaches 8 times or until the number of games reaches 12 times. The special game control means 68 counts the number of winning combinations and the number of games during the RB game, and when either one is satisfied, the RB game is terminated and the normal game is started.

Furthermore, the special game control means 68 controls to shift to the MB1 game or the MB2 game, respectively, on condition that the combination of symbols corresponding to MB1 or MB2 is stopped on the active line, that is, MB1 or MB2 wins. To do.
First, in MB1 game, CB wins (and wins) with a probability of 1/4. When the CB wins, the CB game is executed in the next game. In the CB game, the reel 31 is controlled to stop using the CB game table (except when replay and CB are won), and the combination of symbols corresponding to the small roles 1 to 3 can be stopped on the effective line. Is controlled to stop. Therefore, at the time of non-winning replay in the CB game, it is possible to win a small combination 1 to a small combination 3 according to the skill of the player regardless of the lottery of the combination. Then, when the CB game (1 game) ends, the game returns to the MB1 game again.

In addition, the MB1 game end condition is set such that the number of medals paid out during the MB1 game exceeds the upper limit value or RB is won. Here, the upper limit value of the present embodiment is set to 29 sheets.
Therefore, in this embodiment, the special game control means 68 continues to count the number of medals paid out during the MB1 game and update the number of coins paid out for each game. When it is determined that the counted number of payouts exceeds 29, the special game control means 68 determines that the MB1 game end condition is satisfied, and controls to return to the normal game after the next game. Similarly, when RB is won, it is determined that the MB1 game end condition is satisfied, and control is performed so as to shift to the normal game (inside) after the next game.

  Furthermore, every game and CB game are executed when the game is shifted to the MB2 game. Here, CB lottery is not performed. Therefore, when the CB is won and won, it is different from the MB1 game in which the CB game is executed only for the next game. In addition, the MB2 game end condition is set such that the number of medals paid out during the MB1 game exceeds the upper limit value or RB is won. Here, the upper limit value of the present embodiment is set to 253 sheets.

  Therefore, in the present embodiment, the special game control means 68 counts the number of medals paid out during the MB2 game, and keeps updating the number of medals paid out for each game. When it is determined that the counted number of payouts exceeds 253, the special game control means 68 determines that the MB2 game end condition is satisfied, and controls to return to the normal game after the next game. Similarly, when RB is won, it is determined that the MB2 game end condition is satisfied, and control is performed so as to shift to the normal game (inside) after the next game.

  In addition, as shown in FIG. 2, CB is also drawn in the normal game. If a CB is won and won during a normal game, a CB game (a game in which the role lottery table 62D is used) is executed in the next game (one game). When the CB game ends, the game returns to the normal game again.

Next, a description will be given of the payout rates of the BB game, the RB game, the MB1 game, and the MB2 game.
The payout rate is a value indicating an expected value of the payout number with respect to the number of inserted medals. If the expected value of the payout number is larger than the number of medals inserted, the payout rate exceeds 1, which is advantageous to the player. On the other hand, if the expected value of the payout number is smaller than the number of inserted medals, the payout rate is less than 1, which is advantageous to the player.
In the following calculation, when winning a winning combination, it is assumed that a prize is won with a probability of 100%. In the CB game, it is assumed that the small combination 2 having the largest number of payouts is awarded. Furthermore, it is assumed that three medals are paid out at the time of replay winning. Further, in all games, the number of inserted medals is three.

First, in the BB game and the RB game, the small role 1 is won with a probability of 1/256 and the payout number at the time of winning is two, and the small role 2 is won with the probability of 1/15 and the payout number at the time of winning is There are 10 cards, winning 3 with a probability of 1/80 for small role 3 and paying out 6 when winning, and winning with a probability of 1 / 1.2 for small role 4 and 15 payouts when winning It is. Therefore,
Expected number of payouts = 1/256 × 2 + 1/15 × 10 + 1/80 × 6 + 1 / 1.2 × 15≈13.2
Thus, the expected value of the payout number is larger than the number of inserted medals (three).
Also, the payout rate is
13.2 / 3 = 4.4
And exceeds 1.

Next, in the MB1 game, the number 1 is won with a probability of 1/256 and the number of payouts at the time of winning is 2, and the number of payouts at the time of winning the winning with the probability of 1/15 of the role of 2 is 10 The small role 3 is won with a probability of 1/80 and the number of payouts at the time of winning is six, and the replay is won with a probability of 1 / 7.3 and the number of payouts at the time of winning is three. In addition, CB is won with a probability of 1/4, and in the CB game of the next game, a small role 2 is won and 10 payouts are received. Therefore,
Expected value of payout number = 1/256 × 2 + 1/15 × 10 + 1/80 × 6 + 1 / 7.3 × 3 + 1 / (4 + 1) × 10≈3.16
Thus, the expected value of the payout number is larger than the number of medals inserted.
Also, the payout rate is
3.16 / 3 = 1.05
And exceeds 1.

Furthermore, in MB2 games, every game, small role 2 can be awarded,
Expected number of payouts = 1/1 × 10 = 10
Thus, the expected value of the payout number is larger than the number of medals inserted.
Also, the payout rate is
10/3 = 3.3
And exceeds 1.

  As described above, in the first embodiment, the BB game, the RB game, the MB1 game, and the MB2 game all have a payout rate exceeding 1, and are advantageous games for the player. Also, the payout rate is BB game, RB game, MB2 game, MB1 game in descending order (in order of advantage for the player).

(Production control means)
The effect control means 69 controls the output of effects from the above-described effect output devices (the lamp 21, the speaker 22, and the image display device 23).
The production control means 69 selects the production pattern for each game based on the lottery result of the combination by the combination lottery means 61. Particularly in this embodiment, a plurality of types of effect patterns are provided in advance. Then, the effect control means 69 selects any one effect pattern by lottery using software random numbers after the role lottery means 61 is selected by lottery at the start of the game.

  In addition, a plurality of types of production patterns are provided according to the winning combination. For example, when winning BB, winning RB, winning MB1 or MB2, winning CB, winning small role, not winning, non-internal or internal, non-RT gaming / RT gaming, etc. The production pattern is provided.

As for the production pattern, as to the progress of the game, at what timing (when the start switch 41 is operated, when each stop switch 42 is operated, etc.) what kind of production is output (how the lamp 21 is lit) And what kind of sound is output from the speaker 22, what kind of image is displayed on the image display device 23, etc.).
Then, the effect control means 69 controls to output the effect from the effect output device at a predetermined timing according to the selected effect pattern.

(Game mode control means)
The game mode control means 70 controls whether the game mode during the normal game is a non-RT game or an RT game.
Here, the non-RT game is a game in which a lottery of a combination is performed using the combination lottery table 62A, and the RT game is a game in which a lottery of a combination is performed using the combination lottery table 62B. And the game mode control means 70 is provided with RT flag 70a in order to judge whether it is in RT game.

  First, in the normal game, the game mode selection means 70 turns off the RT flag 70a. In the normal game, when the RT flag 70a is off, the role lottery means 61 uses the role lottery table 62A for lottery. When MB1 or MB2 is won during this normal game, the game mode control means 70 turns on the RT flag 70a and controls to execute the RT game. When the RT flag 70a is turned on, the part lottery means 61 performs a part lottery using the part lottery table 62B. A game in which the RT flag 70a is on (RT game) continues until the winning MB1 or MB2 wins. When MB1 or MB2 wins, the RT flag 70a is turned off from on in the game. Then, depending on the winning MB1 or MB2, the game shifts to MB1 game or MB2 game.

  Here, in the game won for MB1 or MB2, as shown in the winning lottery table 62A of FIG. 3, the winning areas of MB1 and MB2 are both set as overlapping winning areas with replay. For this reason, as described above, in the game, there is no case where the replay wins and the winning MB1 or MB2 wins.

  From the next game, the winning MB1 or MB2 will be carried over, but since it is an RT game, the winning probability of replay will be high (winning probability 1 / 1.2), and there will be an opportunity to win the replay accordingly. To increase. This makes it difficult for MB1 or MB2 that has won the prize to win. Then, in a game where the replay or other combination is not won, MB1 or MB2 carrying over the winning will win.

  The effect control means 69 controls to output an effect indicating which of MB1 or MB2 is won during the RT game. For example, when the production pattern A and the production pattern B are provided and the MB1 winning is carried over, the production pattern A is more easily selected than the production pattern B, and when the MB2 winning is carried over, the production is performed. For example, pattern B is easier to select than effect pattern A. Furthermore, during a game in which the MB1 or MB2 carrying over the winning can be won during the RT game (a game in which the game is not won or one of the small roles is won) (for example, the stop switch 42 is operated) (Before being played) Control is performed so as to perform an effect of notifying which of MB1 or MB2 is won. For example, when the winning of MB1 is carried over, the effect pattern C is selected, and when the winning of MB2 is carried over, the effect pattern D is selected.

  As described above, the RT game is executed until MB1 or MB2 wins while carrying over the winning of either MB1 or MB2. Therefore, while confirming that you have won MB1 or MB2 that can move to a game with a payout rate exceeding 1, preferably expecting you to win MB2 with a higher payout rate, Can be digested.

Next, a game flow in the present embodiment will be described based on a flowchart.
FIG. 5 and FIG. 6 are flowcharts showing the flow of processing during normal games (including non-internal / internal, non-RT games / RT games). FIG. 6 is a flowchart following FIG.
In step S11 of FIG. 5, the game control means 60 continues to detect whether or not medals have been inserted. And when insertion of a medal is detected, such as operating the bet switch 40, it progresses to step S12. In step S12, the game control means 60 continues to detect whether the start switch 41 is turned on. When ON is detected, an effective line is set according to the number of inserted medals, and the process proceeds to step S13. In step S13, it is determined whether the RT flag 70a is on.

  If the RT flag is on, the process proceeds to step S14. If the RT flag is off, the process proceeds to step S15. In step S14, the combination lottery table 62B is set as the combination lottery table 62 used in the game. Then, the process proceeds to step S18. On the other hand, in step S15, it is determined whether or not the special combination flag 63a is on. If not, the process proceeds to step S16, and if it is on, the process proceeds to step S17. In step S16, a role lottery table 62A is set as the role lottery table 62 used in the game. Then, the process proceeds to step S18. On the other hand, in step S17, the role lottery table 62C is set as the role lottery table 62 used in the game. Then, the process proceeds to step S18.

  In step S18, the role lottery means 61 performs the lottery of the role using the role lottery table 62 set in step S14, step S16 or step S17. In the next step S19, the reel control means 64 performs control so as to start the rotation of all the reels 31.

Next, the process proceeds to step S20, and it is determined whether or not MB1 or MB2 has been won by the lottery of the combination in step S18. When it is determined that the winning is made, the process proceeds to step S21, the RT flag 70a is turned on, and the process proceeds to step S22. On the other hand, if it is determined in step S20 that MB1 or MB2 has not been won, the process proceeds to step S22 without performing the process of step S21.
In step S22, it is determined whether or not a special combination (BB, RB, MB1, or MB2, which indicates a specific special combination in this game) is won in the game. Then, the special combination flag 63a is turned on, and the process proceeds to step S24. On the other hand, when it is determined in step S22 that the special combination is not won, the process proceeds to step S24 without performing the process of step S23.

  In step S24, it is determined whether or not the RT flag 70a is on. If it is determined that the RT flag 70a is on, the process proceeds to step S25. If it is determined that the RT flag 70a is not on, the process proceeds to step S26 (FIG. 6). In step S25, the effect control means 69 controls to output the effect during the RT game. Then, the process proceeds to step S26.

In step S26, the stop position determination table 65 corresponding to the winning combination of the game is set. In the next step S27, the game control means 60 continues to determine whether or not the stop switch 42 is turned on. When it is determined that the stop switch 42 has been turned on, the process proceeds to step S28, and the reel control means 64 controls the drive of the motor 32 to perform stop control of the reel 31 corresponding to the turned on stop switch 42.
Next, proceeding to step S29, the game control means 60 determines whether or not all the reels 31 have stopped, and when determining that they have stopped, proceeds to step S30. On the other hand, when it is determined that all the reels 31 have not stopped yet, the process returns to step S27.

  In step S30, the stop symbol determination means 66 determines whether any winning combination has been won (whether the combination of symbols corresponding to any winning combination has stopped on the active line), and determines that winning has occurred. If so, the process proceeds to step S31. On the other hand, when it is determined that no winning is made, the process proceeds to step S34. In step S31, the payout means 67 performs a process such as paying out medals according to the winning combination. For example, when the small combination 3 wins, the number (6) of medals corresponding to the small combination 3 is paid out. Then, the process proceeds to step S32.

  In step S32, the stop symbol determination means 66 determines whether or not a special combination (BB, RB, MB1, MB2 or CB) has won. When it is determined that the special combination has been won, the process proceeds to step S33, and when it is determined that the special combination has not been won, the processing according to this flowchart is terminated. In step S33, it is determined whether either MB1 or MB2 has won. When it is determined that MB1 or MB2 has won, the process proceeds to step S34. When it is determined that MB1 or MB2 has not won, the process proceeds to step S35. In step S34, the RT flag 70a is turned off, and the process proceeds to step S35. In step S35, control is performed so as to shift to the special game, respectively, according to the winning special combination.

(Second Embodiment)
Subsequently, the second embodiment will be described mainly with respect to differences from the first embodiment.
In the second embodiment, first, the winning probabilities of each combination are different as compared to the first embodiment. FIG. 7A is a diagram showing the winning probability of each combination in the second embodiment, and is a diagram corresponding to FIG. 2 of the first embodiment.
In the second embodiment, the winning probabilities of the following special roles are different from those in the first embodiment. As shown in FIG. 7A, the winning probability of BB is set to 1/50, the winning probability of MB1 is set to 1/34, and the winning probability of MB2 is set to 1/70. In addition, the winning probability of RB is set to 1/32768, and the winning probability of CB in MB1 game is set to 1/32768.

  In the second embodiment, the transition (rushing) condition to the RT game is different from that in the first embodiment. In the second embodiment, after the end of the BB game, after the end of the RB game, after the end of the MB1 game, and after the end of the MB2 game, the game shifts to the RT game. The RT game is continued for 10 games. In this RT game period, the lottery of the combination is performed using the combination lottery table 62G unique to the second embodiment. FIG. 7B is a diagram showing a role lottery table 62G used during the RT game of the second embodiment. In the winning lottery table 62G of the second embodiment, winning areas for BB, RB, MB1, and MB2 are provided.

  During the RT game of 10 games, the winning probability of BB is 1/50, the winning probability of RB is 1/32768, the winning probability of MB1 is 1/34, and the winning probability of MB2 is 1/70. As a result, the probability of winning one of the special roles (especially BB, MB1, and MB2) during the RT game is about 48%, and the winning probability is increased.

If any special role (BB, RB, MB1 or MB2) is won during the RT game, the RT lottery table 62B is used during the RT game (inside the normal game and during the RT game). Transition. Then, when the RT game is ended in a state where the winning is carried over, the game using the lottery table 62C (non-RT game inside) becomes a gaming state in which it is easy to win the winning special combination.
On the other hand, if one of the selected special roles (BB, RB, MB1 or MB2) wins during the RT game (before the end of the RT game), the special game (BB game, RB game, MB1 game) starts from the next game. , MB2 game) and a game using a predetermined combination lottery table 62 (any of 62D to 62F).
On the other hand, if no special combination is won during the RT game, after the completion of the RT game, the game shifts to a game using the combination lottery table 62A.

In the second embodiment, the BB game, the RB game, and the MB2 game have the same payout rate as in the first embodiment. On the other hand, in the second embodiment, the payout rate of the MB1 game is different.
In the MB1 game according to the second embodiment, the number 1 is won with a probability of 1/256 and the number of payouts at the time of winning is 2, and the number of payouts at the time of winning with the probability of 1/15 of the small role 2 is 1/15. There are 10 cards, the small role 3 wins with a probability of 1/80 and the number of payouts at the time of winning is 6, and the replay wins with a probability of 1 / 7.3 and the number of payouts at the time of winning is 3 . In addition, CB is elected with a probability of 1/32768, and in the CB game of the next game, a small role 2 is won and 10 payouts are received.

Therefore,
Expected number of payouts = 1/256 × 2 + 1/15 × 10 + 1/80 × 6 + 1 / 7.3 × 3 + 1 / (32768 + 1) × 10≈1.16
Thus, the expected value of the number of payouts is smaller than the number of medals inserted.
Also, the payout rate is
1.16 / 3 = 0.39
Becomes less than 1.

  Therefore, in the second embodiment, in the BB game, the MB2 game, and the RB game, the payout rate exceeds 1, and the game is advantageous to the player. On the other hand, the MB1 game is a disadvantageous game for the player because a game with a payout rate of less than 1 is executed until the end condition (that the payout number has reached 253) is satisfied.

  In the second embodiment, after the end of the BB game, after the end of the RB game, after the end of the MB1 game, or after the end of the MB2 game, the game shifts to the RT game. And between RT games (10 games), BB, RB, MB1 or MB2 is won with a probability of about 48%, so that the player can move to a game with a payout rate exceeding 1 of BB, RB or MB2. RT games will be digested with the expectation of winning (desirably expecting to win the BB with the highest payout rate) and expecting that MB1 has not been won.

8 and 9 are flowcharts showing the flow of games in the second embodiment, which are flowcharts corresponding to FIGS. 5 and 6 of the first embodiment, respectively.
The flowchart of FIG. 8 differs from the flowchart of FIG. 5 in that step S20 and step S21 are not provided in FIG. When it is determined in step S13 that the RT flag 70a is on, the process proceeds to step S41, and 1 is added to the RT game number N (N = N + 1). Then, the process proceeds to step S14.

  Further, the flowchart of FIG. 9 differs from the flowchart of FIG. 6 in the processing after step S32 in FIG. If it is determined in step S32 that the special combination has not won, the process proceeds to step S42. In step S42, it is determined whether N, which is the number of RT games, has become 10 or more. When it is determined that N is 10 or more, the process proceeds to step S43, the RT flag 70a is turned off, and the process according to this flowchart is terminated. On the other hand, when it is determined in step S42 that N is not 10 or more, the processing according to this flowchart is terminated.

If it is determined in step S32 that the special combination is won, the process proceeds to step S44. In step S44, it is determined whether or not the RT flag 70a is on. When it is determined that it is on, the process proceeds to step S45, and when it is determined that it is not on, the process proceeds to step S46. In step S45, the RT flag 70a is turned off, and the process proceeds to step S46. In step S46, the game shifts to a special game according to the winning special combination. Then, the process proceeds to step S47, and during the special game, it is determined whether or not the special game end condition is satisfied. When it is determined that the special game end condition is satisfied, the process proceeds to step S48. In step S48, the RT flag 70a is turned on. And it transfers to a normal game (process after step S11) by step S49. Further, when it is determined in step S47 that the special game end condition is not satisfied, the process proceeds to a normal game (processing after step S11).
Other than the above, the second embodiment is the same as the first embodiment.

(Third embodiment)
Subsequently, the difference between the third embodiment and the second embodiment will be mainly described.
In the third embodiment, the winning probabilities of BB, MB1, and MB2 are different from those of the second embodiment. FIG. 10 is a diagram showing the winning probabilities of each combination in the third embodiment, and corresponds to FIG. 7A of the second embodiment.
In the third embodiment, as shown in FIG. 10, the winning probability of BB is set to 1/2, the winning probability of MB1 is set to 1/6, and the winning probability of MB2 is set to 1/6. Others are the same as 2nd Embodiment.
By setting the winning probability in this way, the probability of winning BB, MB1, or MB2 during RT games (between 10 games) can be set to almost 100%.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to embodiment mentioned above, For example, the following various deformation | transformation is possible.
(1) In this embodiment, medals are used as game media. However, the present invention can also be applied to slot machines that use game media other than medals, such as game balls.
(2) The types of winning combinations, the winning probabilities, the number of payouts, etc. shown in FIGS. 2, 7, and 9 are examples, and various other settings can be made.

(3) As another special combination, an SB (single bonus; only one game, a combination for shifting to an SB game in which a game similar to the BB game is performed) may be provided.
(4) When to enter the RT game and end the RT game is not limited to that shown in the present embodiment, and various conditions can be arbitrarily set.

(5) In this embodiment, when the replay and other winning combination are won, the replay always wins. However, the present invention is not limited to this. For example, the replay is given priority (not necessarily) (You may not win the winning replay).
(6) Also, in this embodiment, MB1 and MB2 are always allowed to win when they are carrying over the win and not winning the replay, but not limited to this, like BB and RB, You may not necessarily win.

  (7) In the first embodiment, when MB1 or MB2 is won, the game shifts to RT game. However, in addition to this, when a predetermined condition is satisfied (for example, when a lottery for transitioning to RT games is performed and winning in that lottery), transition to RT games (even if MB1 or MB2 is not won) You may make it do. As a result, after the RT game is completed, it is possible to select a game that has won MB1 or MB2 and a game that has not won them.

  (8) In the first embodiment, both the MB1 game and the MB2 game are set to games with a payout rate exceeding 1. However, the present invention is not limited to this, and as in the second embodiment, MB1 may be set to a game in which the payout rate is less than 1. Further, in the second embodiment, the MB1 game is set to a game with a payout rate lower than 1, and the MB2 game is set to a game with a payout rate higher than 1. However, the present invention is not limited to this, and as in the first embodiment, the MB1 game may be set to a game in which the game play rate exceeds 1 (however, the game play rate is different between the MB1 game and the MB2 game). good. Furthermore, although BB, MB2, and MB1 are provided in both the first and second embodiments, the present invention is not limited to this, and only BB and MB2, only BB and MB1, or only MB2 and MB1 may be provided.
