Description

  The present invention relates to a slot machine in which a winning rate is changed by changing the winning probability of a combination and the number of game media paid out at the time of winning in accordance with the gaming state.

In a conventional slot machine, there is known a slot machine in which BB (Big Bonus) is provided as a special role, and when BB is won or won, the game is shifted to BB game.
In this type of slot machine, when the game shifts to the BB game, the general game (first game) is started first. In this general game, the game is played by inserting three medals as in the normal game. When the transition combination is won and won during the general game, a bonus game (second game) is started from the next game. In addition, the winning probability of the transitional combination in the general game of the BB game is about 1/3 to 1/6.

In addition, during the bonus game, the number of medals received is only one, and a gaming state in which a predetermined combination is won with a high probability. Since the maximum number of medals to be paid out at the predetermined winning combination is set to 15 at the maximum, the bonus game is positioned as a game with a high payout rate (for example, paragraph numbers “0069” to “0069” in Patent Document 1). (Refer to “0072”).

  However, in the above-described conventional technology, the number of inserted medals is determined in advance such as 3 in the general game of the BB game and 1 in the bonus game of the BB game. Since it is set to increase the number of net increase, there is a problem that game contents are uniform in many slot machines.

  Therefore, the problem to be solved by the present invention is to change the winning rate especially in special games by changing the winning probability of a combination and the number of game media payout at the time of winning according to the game state. .

The present invention solves the above-described problems by the following means.
(Claim 1)
In the invention of claim 1, a combination of a combination lottery table that determines a winning probability of a combination, a combination lottery means for performing a lottery of a combination using the combination lottery table, and a symbol corresponding to one of the combinations is an effective line. When stopped, payout means for controlling the number of game media to be paid out according to the combination, and a special combination is won by the combination lottery means during a normal game, and a combination of symbols corresponding to the special combination is determined. Special game control means for controlling to execute a special game when stopped on the active line, the special game control means being thrown into the first game and per game during the special game The first game is controlled so as to execute a second game in which a payout rate representing an expected value of the number of game media to be paid out with respect to the number of game media is set lower than the first game. During that time, the winning combination is won by the above-mentioned lottery means. When a combination of symbols corresponding to the transition combination is stopped on the activated line, said to shift to the second game from the first game, in the second game, or game number reaches the specified number of times, or said second A game that is paid out during the special game when the predetermined number of winnings drawn by the combination lottery means during the game reaches the specified number of times. The control is repeated until the number of media reaches a predetermined number, and when the number of game media paid out during the special game reaches a predetermined number, the special game is terminated. During one game, the number of game media inserted is set to n and the game is set to be played. During the second game, the number of game media inserted is set to m (m> n). During the first game, When the player wins the migration role in serial combination lottery means is characterized in that it is possible to set it so as not to stop the activated line combination of symbols corresponding to the transition role.

According to the first aspect of the present invention, the first game and the second game are executed during the special game. Also, the payout rate representing the expected value of the number of game media to be paid out relative to the number of game media inserted per game is set lower in the second game than in the first game. Furthermore, during the first game, when the winning combination is won by the winning lottery means, and the combination of symbols corresponding to the transferring combination stops on the active line, the first game is shifted to the second game. Further, during the second game, when the number of games reaches the specified number of times, or when the number of winnings of the predetermined role reaches the specified number of times, the game shifts from the second game to the first game. Such an operation is repeated until a special game end condition is satisfied. The special game end condition is that the number of game media paid out during the special game has reached a predetermined number. Furthermore, during the first game, the number of game media inserted is set to n and the game is set to be played. During the second game, the number of game media inserted is set to m (m> n). Is set to do. During the first game, when the winning combination is won by the winning lottery means, the combination of symbols corresponding to the winning combination is set so as not to be stopped on the active line.

In the following embodiment, m is 3 (medals) and n is 1. In addition, the payout rate during the first game is 12.66, and the payout rate during the second game is 1.515. Furthermore, during the second game, when the number of games reaches 12 times, or when the number of winnings of a predetermined role reaches 8, the second game is terminated and the first game is returned to. Further, when the number of medals paid out during the special game exceeds 465, the special game is terminated.

(Claim 2)
According to a second aspect of the present invention, in the slot machine according to the first aspect, when the transition combination is won by the combination lottery means during the first game, a transition combination winning notification unit is provided for notifying that effect. It is characterized by.

In the invention of claim 2 , when the transition combination is won by the combination lottery means during the first game, the fact is notified.

(Claim 1)
According to the invention of claim 1, since the special game end condition is set such that the number of game media paid out during the special game exceeds the upper limit, the number of game media input can be reduced. As the number of game media is increased, the number of games in the second game is reduced and the number of games in the first game is increased, which is more advantageous for the player. Become. Therefore, it is advantageous to play the first game as much as possible and not shift to the second game.

(Claim 2)
According to the invention of claim 2, it is possible to give the player an opportunity to avoid winning the transitional role.

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 control of the reel 31, and the payout at the time of winning, Control the output of the production.

  The game control means 60 is provided on a control board, and performs various controls by the CPU that performs calculations, a ROM that stores programs necessary for the progress of games, data for effects, and the like. A RAM or the like for temporarily storing the fetched data or the like when performing.

(Bet switch, start switch, stop 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 when a game is started, and is a switch for setting 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 is ring-shaped, and a reel tape on which a plurality of types of symbols (such as symbols constituting a role) are 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 receiving this signal, the game control means 60 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, a reel stop control means 64 described later) receives this signal, the game control means 60 controls driving of the motor 32 corresponding to the stop switch 42 and stops the reel 31 related to the motor 32. Take control.

  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))
Furthermore, 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.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
Furthermore, the image display device 23 includes a liquid crystal image display device, a dot display, and the like, and displays various effect images during the game.
Although illustration is omitted in the present embodiment, an effect control unit that controls the entire effect is provided, and the output of the effect output device (the lamp 21, the speaker 22, and the image display device 23) is controlled by the effect control unit. Is done.

  At the start of the game, the player operates the bet switch 40 to insert a previously stored medal, or inserts a medal from the medal slot to set an effective line, 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, the combination of symbols of any combination stops on the active line, and when a winning combination of the combination is made, a medal is paid out according to the established combination.

(Design combination line, effective line)
Although not shown, a symbol combination 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 inserted medals. 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” is a line that is not set as an effective line among symbol combination lines, and even if a combination of symbols corresponding to any combination stops on that line, This is a line that does not give profits (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 the present embodiment, the number of medals inserted in the normal game, the second game (bonus game) of the BB game, and the RB game is set to only three. In addition, the number of inserted medals in the first game (general game) of the BB game is set to only one.
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 3, all symbol combination lines (a total of 5) are set as valid lines, and there are no invalid lines.

  In the present embodiment, it is not assumed that the number of inserted medals is two. However, if the number of inserted medals is two, the symbol combination lines in the horizontal middle, upper, and lower (three in total) ) Is set as an effective line, and the other two symbol combination lines are set as invalid lines.

(Role)
FIG. 2 is a diagram showing the combinations set in the combination lottery table 62 (a first combination lottery table 62a to a third combination lottery table 62c described later) and their winning probabilities. FIG. 2 also shows the number of payouts at the time of winning a combination. As shown in FIG. 2, in this embodiment, BB and RB which are special roles, small roles 1, small roles 2 and 3 which are small roles, replays, transitional roles and predetermined roles are provided as roles. Yes.

  The special role is a role that shifts from a normal game to a special game (a game that can be expected to win medals more than a normal game and is advantageous to the player). In the present embodiment, BB (Big Bonus) and RB (Regular Bonus) are provided as special roles. BB is a role for shifting to a BB game, which is one of special games, and RB is a role for shifting to an RB game, which is another one of special games. In addition, although SB (single bonus) is mentioned as another special combination, in this embodiment, BB and RB are provided and SB is not provided.

The small combination is a combination in which a predetermined number of medals are paid out. In this embodiment, three types of small combinations 1 to 3 are provided. As shown in FIG. 2, the small combinations 1 to 3 are set such that the combination of the corresponding symbols and the number of medals to be paid out differ depending on the type of the small combination. Further, the small combination 2 in the present embodiment is a combination corresponding to the specific small combination in the present invention, and is a combination in which the winning probability and the number of medals to be paid out at the time of winning are changed according to the number of inserted medals.
Furthermore, the replay is a re-playing role that allows the re-playing while maintaining the number of medals inserted in the game.

Furthermore, the transitional combination is a combination that is drawn by lottery only during the first game of the BB game. When the winning combination is won and won, the BB game shifts from the first game to the second game.
Further, the predetermined combination is a combination that is drawn in the second game of the BB game and in the RB game. Like the small combination, a predetermined number of medals are paid out when winning or winning.

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. .
Special roles (BB and RB) are mentioned as the carry-over. When the special role is won, when the reel 31 is stopped, the special combination is won after the next game until the combination of symbols corresponding to the special role stops on the active line (until the special role is won). It is controlled to carry over.

  A game in which a special role is not won, that is, a game in which a special role is not carried over is referred to as “non-inside”. In addition, a special combination is won in the game or in the previous game, but the combination of symbols corresponding to the selected special combination is not stopped on the active line (not winning), that is, the special combination A game in which the winning is carried over is called "inside".

  As described above, the winning of the special role is carried over, but no role other than the special role is carried over. When a role other than the special role is won in the lottery of the 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. Note that “stop (winning) is possible” means that the reel 31 stops (wins) within the range of the stoppable position of the reel 31 (within the range of stop control).

  In addition, combinations of symbols of the reel 31 corresponding to the above various combinations are determined in advance. In FIG. 2, what is displayed in parentheses on the right side of each combination indicates a symbol constituting a combination of symbols on the reel 31. For example, the symbol combination of BB is “7”-“7”-“7”, and the symbol combination of RB is “BAR”-“BAR”-“BAR”.

  In such a case, 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 made, the number of medals corresponding to the combination is received. To be paid out. For example, when all the reels 31 are stopped and the symbol combination “watermelon”-“watermelon”-“watermelon” is stopped on one of the active lines, a small role 1 is won and 12 medals are awarded. Will be 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 of a role (BB and RB, which are the special roles described above, small role 1, small role 2, and small role 3, replay, transitional role or predetermined role). The role lottery means 61 includes, for example, a random number generator for hardware lottery (a random number generator composed of hardware), a random number extractor that extracts a random number generated by the random number generator, and a random 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 (random number generator) of this embodiment generates a 16-bit random number (for example, 0 to 65535 in decimal notation). 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 (operated) by the player. The determination unit determines the combination corresponding to the area 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 70 described later. For example, if the extracted random number value belongs to the BB winning area, it is determined as BB winning, and if it belongs to the non-winning area, it is determined as non-winning.

  In the normal game (non-inside), the role lottery means 61, as shown in FIG. 2, BB and RB which are special roles, small roles 1, small roles 2 and 3 which are small roles, replay and non-play Based on the random number extracted from the winning, the presence / absence of winning and the winning combination are determined.

(Role drawing table)
As shown in FIG. 2, the combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. The 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. The predetermined ratio is set so as to be.

Further, the role lottery table 62 is provided with a specific role lottery table 62 for each gaming state (normal game and special game).
First, a first combination lottery table 62a is provided as a combination lottery table 62 used for normal games. In the first combination lottery table 62a, when the special combination is won during the normal game and becomes the inside, the special combination is excluded from the combination selected.

  The second combination lottery table 62b is used in the first game of the BB game. In the first game of the BB game, unlike the normal game, the special combination and the replay are not drawn. Furthermore, the small role is drawn in the same manner as in the normal game. Further, a transitional role is provided as a role unique to the first game of the BB game.

The third combination lottery table 62c is used in the second game of the BB game and the RB game. In the second game of the BB game, only a predetermined combination is provided as a combination to be drawn.
Although not shown, the winning area and the non-winning area of each combination in the combination lottery table 62 are determined for each set value of the payout rate.

  Furthermore, as shown in FIG. 2, the first combination lottery table 62a and the third combination lottery table 62c define the winning combination probability when the number of inserted medals is three. This is because the number of medals inserted is set (limited) to 3 in the normal game using the first combination lottery table 62a and the second game and RB game of the BB game using the third combination lottery table 62c. Because.

  Further, the second combination lottery table 62b defines the winning probability of the combination when the number of inserted medals is one. This is because in the first game of the BB game in which the second combination lottery table 62b is used, the medal insertion number is set (limited) to one.

Furthermore, the winning probability of each winning combination and the number of medals to be paid out when winning each winning combination are set to have a predetermined payout rate.
Here, the payout rate represents an expected value of the number of medals to be paid out with respect to the number of medals inserted per game. That is, when the payout rate exceeds 1, the number of owned medals increases, and when the payout rate falls below 1, the number of owned medals decreases.

For example, the payout rate during the first game of the BB game is as follows.
First, the expected value of the number of payouts per game is
12/100 (small role 1) + 15 / 1.2 (small role 2) +2/64 (small role 3) +1/100 (transfer role)
≒ 12.66 (sheets)
It becomes.

Therefore, the payout rate is
12.66 (expected value of payout number) / 1 (number of input)
= 12.66
It becomes.

In addition, the payout ratio during the second game of the BB game and during the RB game is as follows.
First, the expected value of the number of payouts per game is
5 / 1.1 (predetermined role)
≒ 4.545 (sheets)
It becomes.

Therefore, the payout rate is
4.545 (expected number of payouts) / 3 (number of inserts)
= 1.515
It becomes.

As described above, during the BB game, both the first game and the second game have a payout rate exceeding 1. However, in the BB game, the first game has a higher payout rate than the second game.
Although details will be described later, in this embodiment, the BB game end condition is set such that the number of medals paid out during the BB game exceeds the upper limit. For this reason, if the number of inserted medals is reduced and the BB game is digested, the number of medals is increased. That is, it is more advantageous for the player to increase the number of games of the first game by decreasing the number of games of the second game.
Therefore, in this embodiment, it is advantageous to play the first game as much as possible and not shift to the second game.

(Means to carry over special roles)
In the game until the special combination (BB or RB) is won, until the combination of symbols corresponding to the special combination stops on the active line (until the special combination wins), It controls to carry on the special role winning after the next game.

  In the present embodiment, when a special combination is won, a special combination flag 63a is provided for each type of special combination in order to store the special combination. For example, when winning BB, the special combination flag 63a related to BB is turned on (from OFF), and when winning RB, the special combination flag 63a related to RB is turned on. The on state of these special combination flags 63a is maintained until BB or RB wins, and is turned from on to off when BB or RB wins.

(Reel stop control means)
The reel stop control means 64 is based on the lottery result of the winning combination by the winning lottery means 61 when the stop switch 42 is operated and the timing when the stop switch 42 is operated. , The stop position of the reel 31 corresponding to the stop switch 42 is determined, and the motor 32 is driven and controlled to stop the reel 31 at the determined position.

  For example, in the game where the small combination 1 is won, the reel stop control means 64 is a combination of symbols corresponding to the small combination 1 ("watermelon"-"watermelon"-"watermelon") within the range where the reel 31 can be stopped. The reel 31 is controlled to stop on the effective line, and the reel 31 is controlled to stop the combination of symbols corresponding to the combination other than the small combination 1 on the effective line.

  In addition, the reel stop control means 64, when the game won for the special role or the special role win is carried over (the special role flag 63a is on), and the special role is not selected in the game. The reel 31 is controlled to stop so that the combination of symbols corresponding to is stopped on the effective line.

(Stop position determination table)
The stop position determination table 65 defines the stop position 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 stop position determination table 65 is provided for each combination. The BB table, the RB table, the small combination 1 table, the small combination 2 table, the small combination 3 table, the replay table, the transition combination table, the predetermined combination table, and the non-winning table. Provide a table.

The BB table is a game won by BB, or a case where BB is won (when the special combination flag 63a related to BB is turned on) and no combination is won in the game. Is used as a condition.
In addition, the RB table is a game won for RB, or when the RB is won (when the special combination flag 63a related to RB is turned on), and any combination is won in the game. It is used on condition that there is no.

Furthermore, the small role 1 table, the small role 2 table, the small role 3 table, the replay table, the transitional role table, or the predetermined role table are the small role 1, small role 2, small role 3, replay, transitional role or predetermined, respectively. Used in games when winning a role.
Further, the non-winning table is used in a game in which no winning combination is won.

In addition, the BB table, the RB table, the small role 1 table, the small role 2 table, the small role 3 table, the replay table, the transitional role table, or the predetermined role table are within the range of the stoptable position of the reel 31, respectively. , RB, small combination 1, small combination 2, small combination 3, replay, transition combination or combination of symbols corresponding to a predetermined combination is stopped on the active line and a combination other than the combination (for example, small combination in the small combination 1 table) The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the combination other than 1) is not stopped on the effective line.
Furthermore, the non-winning table defines a combination of symbols when the reel 31 is stopped so that a combination of symbols corresponding to any combination is not stopped on the active line.

  Here, in the present embodiment, “within the range where the reel 31 can be stopped” in the stop position determination table 65 means (1) from when the stop switch 42 is operated (momentary) to when the reel 31 is stopped. This means that the movement control amount of the reel 31 is within 5 symbols, or (2) the stop control time from when the stop switch 42 is operated (instant) until the reel 31 is stopped is within 190 ms.

  Using any of the stop position determination tables 65 described above, the reel stop control means 64, when stopping the combination of symbols corresponding to any of the combinations on the effective line, within the range of the stoptable position of the reel 31. Then, control is performed so that the symbols constituting the combination of symbols corresponding to the combination are stopped on the active line.

  In addition, when a small combination or replay is won during the normal game, the small combination or replay won in the game is given priority as the winning combination. In the normal game, the combination of symbols corresponding to the special combination can be stopped on the active line. However, in the game, the small combination or replay won in the game is given priority, and the reel stop control means 64 Then, the reel 31 is controlled to stop so that the selected small role or replay can be won. That is, in this case, the BB table or the RB table is not used, and the small combination 1 to small combination 3 table or the replay table is used.

(Stop symbol discrimination means)
The stop symbol discriminating means 66 discriminates 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 discriminating means 66 discriminates the symbol on the effective line by detecting, for example, the angle or the number of steps when the motor 32 is stopped.

  The stop symbol discriminating means 66 does not discriminate the symbol combination after the reel 31 is actually stopped. Instead, the stop symbol discriminating unit 66 uses the stop position determination table 65 to determine the reel from the position of the reel 31 at the moment when the stop switch 42 is operated. It is also possible to determine a combination of symbols on the effective line when 31 stop positions are determined.

(Payment means)
The payout unit 67 determines that the combination of symbols stopped on the active line when the reel 31 is stopped matches the combination of symbols corresponding to any of the combinations by the stop symbol determining unit 66 and the winning combination is won. In addition, a predetermined number of medals corresponding to the winning combination is paid out to the player, 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 or RB game) (transition from the normal game to the special game), progress of the game during the special game, and end of the special game (from the special game to the normal game). Transition) 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, the special game control means 68 is used to inform the player that the game is to be transferred to the special game when shifting to the special game, that is, the lamp 21 is turned on, the sound is output from the speaker 22, and the image display device 23 is used. Control is performed to perform various effects such as image display.

  First, during the 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.

  When the BB game is started, the special game control means 68 first starts the first game (general game). When the transition combination is won during the first game of the BB game and the transition combination wins, the second game (bonus game) is started from the next game. During the second game, the number of games or the number of winning of a predetermined role is counted. When the number of games reaches the specified number of times (12 in this embodiment) or when the number of winning a predetermined role reaches the specified number of times (8 in this embodiment), the second game is terminated, Control to return to the game. Then, during the first game, the game is continued until the winning combination is won and won, and when the winning combination wins, control is performed so that the second game is transferred again.

In this way, during the BB game, the first game and the second game are moved back and forth until the end condition is satisfied.
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 465 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 value (exceeds 465), it determines that the BB game end condition is satisfied.

  When the number of payouts in the game exceeds 465, it is determined that the upper limit has been exceeded, and the BB game ends in the game. On the other hand, when the number of payouts in the game is 465 or less, it is not determined that the upper limit value has been exceeded, so that the BB game is also performed in the next game. For example, when the number of payouts is 465 at the end of the game, it is not determined that the upper limit has been exceeded, so the process proceeds to the next game. Then, when the small game 1 (15 cards) is won and won in the next game, the payout number in the BB game is 465 + 15 = 480 cards.

  In the RB game, the second game in the above-mentioned BB game is performed until one set, that is, until the number of wins for a predetermined role reaches eight times or until the number of games reaches twelve times. In the RB game, the special game control means 68 continues to count the number of games or the number of winnings of a predetermined role.

(Transitioning role winning notification means)
Furthermore, the special game control means 68 of this embodiment includes a transition combination winning notification means 68a.
The transition combination winning notification means 68a notifies that when the transition combination is won in the first game of the BB game.

As described above, in the first game of the BB game, only one medal is inserted to play a game, and the winning probability of the small role 2 is high, and the payout number at the time of winning is as many as 15. For this reason, in the BB game, the net increase in the number of medals in the BB game increases when only the first game is played. Therefore, when winning the transition combination during the first game, it is better not to win the transition combination. Therefore, in the present embodiment, the player is given an opportunity to avoid winning the transitional role by notifying the fact when the transitional role is won.
The effect output device used for the notification may be any of the lamp 21, the speaker 22, and the image display device 23 described above.

In addition, there are various methods for setting so that the winning combination can be prevented from winning when the winning combination is won.
For example, as a first method, when the combination of symbols corresponding to the transition combination is “SRB”-“SRB”-“SRB”, when the stop switch 42 is pressed in the order of “right” and “middle”, “ Each reel 31 is controlled to stop so that the symbols “in rotation” — “SRB” — “SRB” stop. Here, with respect to the middle reel 31 and the right reel 31, all the symbols of “SRB” are arranged at intervals within 5 symbols, but with respect to the left reel 31, “SRB” is spaced at intervals of 6 symbols or more. A range is provided. In this way, with respect to the left reel 31, the stop switch 42 can be operated so that the symbol "SRB" does not stop on the active line.

  As a second method, in the transition combination table, each of the reels is set such that “SRB”-“SRB”-“SRB” always stops at the active line when the left middle right and the stop switch 42 are pressed in order. 31 is controlled to stop. On the other hand, when the right middle left and the stop switch 42 are reversely pressed, the reels 31 are controlled to stop so that “SRB”-“SRB”-“SRB” does not stop on the active line. In this way, if the player knows the winning combination of the transitional combination, the player can prevent the transitional combination from winning by simply pressing the stop switch 42 in the reverse order.

Next, the flow of processing during a game in the present embodiment will be described based on a flowchart.
3 and 4 are flowcharts showing the flow of processing during the BB game. FIG. 4 is a flowchart following FIG.
First, in step S11, the special game control means 68 performs a first game start process.
In the next step S12, the game control means 60 continues to detect whether or not the start switch 41 is turned on, and when on is detected, the process proceeds to step S13. In step S <b> 13, the game control unit 60 controls to start rotation of all the reels 31. Here, since one medal is inserted in the first game of the BB game, one effective line in the horizontal middle stage is determined. In the next step S14, the part lottery means 61 performs a part lottery. Note that the winning combinations are a small combination and a transitional combination as shown in FIG.

  In the next step S15, it is determined whether or not the winning combination is won in the drawing of the winning combination in step S14. When it is determined that the winning combination is won, the process proceeds to step S16. When it is determined that the winning combination is not won, the process proceeds to step S17. In step S16, the transition combination winning notification means 68a notifies that the transition combination is won, and proceeds to step S17.

  In step S17, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S18. In step S18, the reel stop control means 64 uses the stop position determination table 65 corresponding to the lottery result of the combination in step S14 to determine the stop position of the reel 31 related to the operated stop switch 42 and the motor. 32 is driven and controlled to stop the reel 31 at the determined position.

  Next, proceeding to step S19, 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 S20. On the other hand, when it is determined that all the reels 31 have not been stopped, the process returns to step S17.

  In step S20, the stop symbol determination means 66 determines whether or not any combination has won, that is, whether or not a combination of symbols corresponding to any combination has stopped on the active line. When it is determined that it has stopped, the process proceeds to step S21. When it is determined that it has not stopped, the process returns to step S12 to continue the first game. In step S21, the payout means 67 performs a medal payout process corresponding to the winning combination. Then, the process proceeds to step S22.

  In step S22, the special game control means 68 performs a process of updating the number of medals to be paid out (total number) during the BB game. Specifically, when the payout process is performed in step S21, a process of adding the number of medals paid out is performed. Next, proceeding to step S23, the special game control means 68 determines whether or not the number of medals paid out in the BB game exceeds the upper limit M (465 in this embodiment). When it is determined that the upper limit value M has been exceeded, the special game control means 68 controls to end the BB game. On the other hand, when it is determined that the upper limit value M is not exceeded, the process proceeds to step S24.

  In step S24, the stop symbol determination means 66 determines whether or not the transition combination has won a prize in the game. If it is determined that the winning combination has won, the process proceeds to step S31 (FIG. 4) and subsequent steps. On the other hand, when it is determined that the winning combination has not won, the process returns to step S12 to control the first game to be continued.

  In step S31, the special game control means 68 performs the second game start process. Specifically, an initial value is set for the (remaining) game count X of the second game (in this embodiment, an initial value of the game count X = 12), and an initial value is set for the (remaining) winning count Y. (In this embodiment, the initial value of the number of winning times Y = 8).

  In the next step S32, the game control means 60 continues to detect whether or not the start switch 41 is turned on. When the start switch 41 is detected, the game control means 60 proceeds to step S33, and the game control means 60 rotates the reels 31. Control to start. Here, since three medals are inserted in the second game, five effective lines are determined. In the next step S34, the special game control means 68 subtracts 1 from the number X of games of the second game (X = X-1). In the next step S35, the part lottery means 61 performs a part lottery. As shown in FIG. 2, only a predetermined combination is selected as a winning combination.

  In the next step S36, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S37. In step S37, the reel stop control means 64 follows the stop position determination table 65 corresponding to the lottery result of the combination in step S35 (the predetermined combination table when the predetermined combination is won or the non-winning table when the combination is not selected). The stop position of the reel 31 is determined based on the timing when the stop switch 42 is operated, and the reel 31 is controlled to stop at the determined position. Then, the process proceeds to step S38.

  In step S38, the game control means 60 determines whether or not all the reels 31 are stopped. If it is determined that all the reels 31 are stopped, the process proceeds to step S39. On the other hand, when it is determined in step S38 that all the reels 31 are not stopped, the process returns to step S36.

  In step S39, the stop symbol determination means 66 determines whether or not the combination of symbols corresponding to the predetermined combination has stopped on the active line (whether or not the predetermined combination has won a prize). When it is determined that the predetermined combination has won, the process proceeds to step S40. On the other hand, when it is determined that the predetermined combination has not won, the process proceeds to step S44.

In step S40, the payout means 67 pays out medals corresponding to a predetermined winning combination (payout of 15 medals), and proceeds to step S41. In step S41, the special game control means 68 updates the payout number (total number) of medals in the BB game, and proceeds to step S42.
In step S42, the special game control means 68 subtracts 1 from the winning count Y of the second game (Y = Y-1). Then, the process proceeds to step S43.

In step S43, the special game control means 68 determines whether or not the number of medals paid out exceeds the upper limit value M. When it is determined that the upper limit value M has been exceeded, the special game control means 68 controls to end the BB game. On the other hand, when it is determined that the upper limit value M is not exceeded, the process proceeds to step S44.
In step S44, the special game control means 68 determines whether or not the second game end condition is satisfied. In the present embodiment, it is determined that the condition for ending the second game is satisfied when the predetermined game winning number in the second game is 8 or the game number is 12.

  When it is determined that the end condition is satisfied, the process returns to step 11 and the control is performed so that the first game of the BB game is started again. On the other hand, if it is determined in step S44 that it is not yet satisfied, the process returns to step S32, and the special game control means 68 continues the second game.

  In addition, about the flow of RB game, illustration by a flowchart is abbreviate | omitted. When the RB game is entered, the processing after step S31 in FIG. 4 is performed. However, in the RB game, the process of step S43 (determination of whether or not the number of payouts exceeds the upper limit value) is not performed. In the RB game, when at least one of X = 0 or Y = 0 is satisfied in step S44, the RB game is controlled to end.
