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 enables an effective line by the operation. Although the medal insertion slot is not shown in FIG. 1, the medal insertion slot is a part where the medal is actually inserted in order to validate the effective line, like 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 combination of symbols corresponding to a combination) is attached is attached to an 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 this embodiment, three reels 31 (left, middle, and right) are provided as described above, and corresponding to this, three stop switches 42 are provided, left, middle, and right. It has been. 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.

(Lamp, speaker, image display device)
Furthermore, the output side of the game control means 60 is electrically connected to the lamp 21, the speaker 22, and the effect output device of the image display device 23. The production output device is not limited to these.

  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) arranged on the inner peripheral side of each reel 31, an upper lamp and a side lamp which are arranged on the front surface of the casing of the slot machine 10 and blink when a winning combination is made. A lamp (not shown) and the like are included.

Furthermore, the image display device 23 includes a liquid crystal image display device, a dot display, and 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 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, when the combination of symbols of the reels 31 on the active line matches a predetermined combination of symbols of a certain combination and the winning combination of that combination is won, Payout etc. are performed.

(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.
Here, the “effective line” is a line for winning a winning combination when a combination of symbols corresponding to any of the winning combinations is stopped on that 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 this embodiment, in all games, the number of inserted medals is set to 3, and all of the five symbol combination lines are set to valid lines. Therefore, there is no case where the medals are played by inserting one or two medals, and there is no invalid line in this embodiment.

(Role)
FIG. 2 is a diagram showing the types of combinations, combinations of symbols, and winning probabilities in the present embodiment. As the types of combinations in the present embodiment, specific combinations, small combinations, replays, and SRBs are provided.
The specific combination is a combination for executing a specific game. In the present embodiment, two types of 1BB (first specific combination) and 2BB (second specific combination) are provided. 1BB is a role for shifting to a 1BB game (first specific game), which is one of the specific games, and 2BB is a role for shifting to 2BB game (second specific game), which is another one of the specific games. is there.

The small combination is a combination in which a predetermined number of medals are paid out. In this embodiment, three types of small combination 1 to small combination 3 are provided.
Furthermore, the replay is a re-playing role that enables a re-play that maintains the number of inserted medals (the number of bets) in the game.

  Further, the SRB is a bonus game transitioning role, which is a lottery during the general game of the 1BB game, and a role for shifting from the general game to the bonus game during the 1BB game. As shown in FIG. 2, five types of SRBs, SRB1 to SRB5, are provided as SRB types. Depending on the type, the specified number (upper limit number) P of winning combinations in the bonus game and the game content after the bonus game are set to be different. As shown in FIG. 2, in SRB1 to SRB3, the prescribed number P of winning combinations in the bonus game is set to 8 times. On the other hand, in SRB4 and SRB5, the prescribed number P of winning combinations in the bonus game is set to two.

  Furthermore, when an SRB is won and a bonus game is entered, an RT game may be executed after the bonus game ends. The number Q of RT games varies depending on the SRB. As shown in FIG. 2, the SRB 3 has a RT game count Q of 0, while the SRB 1 and SRB 4 have the RT game count Q set to 500. Furthermore, in SRB2 and SRB5, the number Q of RT games is set to 100 times.

  Here, the RT game is a game in which the replay winning probability is set higher than the non-winning probability and the winning probabilities of other roles. As a result, during RT games, replays are frequently won and won. Therefore, in the RT game, there are more opportunities to start the next game without inserting medals, and the game can be continued without reducing the number of medals. As shown in FIG. 2, during the general game of 1BB game, the winning probability of replay is 1 / 7.3, which is the same as that of normal game, but when transitioning to RT game, as shown in parentheses in FIG. The winning probability of replay is 1 / 1.2, which is higher than other winning combinations (for example, 1/15 of small role 1) and non-winning probability (1 / 11.92).

Further, the combination is determined for each gaming state (during normal gaming (inside / non-inside) and during a specific game).
Here, the concept called non-inside and inside is provided in the normal game. “Non-inside” means a gaming state in which a specific combination is not won. On the other hand, “inside” means that a specific combination is won in the game or a game before that, but the combination of symbols corresponding to the selected specific combination is not stopped on the active line (no winning) Refers to the game state.

In the present embodiment, as a combination during normal game (non-inside), a specific combination (1BB and 2BB), three types of small combinations (small combination 1, small combination 2 and small combination 3), and replay are provided. Yes.
On the other hand, the combination in the normal game (inside) is a combination obtained by removing the specific combination from the combination in the non-internal normal game. That is, in a normal game, a special combination lottery is performed during non-inside, but a specific combination lottery is not performed when a specific combination is won and the internal combination is entered.

Furthermore, the 1BB game is provided with a general game and a bonus game, and as shown in FIG. 2, three types of small roles (small role 1, small role 2) are provided as general roles in the 1BB game. And small role 3), replay and SRB are provided.
Further, the bonus game of the 1BB game is a game in which a small combination 1 to a small combination 3 and a predetermined combination are drawn by lottery, and a game in which a predetermined combination is won and won.
The predetermined combination and the small combination 1 have the same combination of symbols and the number of payouts, and can be regarded as the same combination. In this way, during the general game of 1BB game, the winning probability of the small role 1 is 1/15, but in the bonus game of 1BB game, the winning probability of the small role 1 (including the predetermined role) is 1 /15+1/1.1. That is, in the 1BB game bonus game, it can be said that the winning probability of the small role 1 is increased.

  In the 2BB game, a replay lottery is performed, but a small combination 1 to a small combination 3 are not drawn. However, during the 2BB game, the small combination 1 to the small combination 3 are controlled so as to be stopped on the active line depending on the skill of the player. Details of this point will be described later.

Furthermore, as shown in FIG. 2, the combination of symbols of the reels 31 corresponding to the various types of roles described above is determined in advance, and when any of the reels 31 is stopped, it corresponds to one of the predetermined roles. When the combination of symbols to be stopped stops on the active line and the winning combination is made, a predetermined number of medals are paid out, although not shown in FIG.
However, the combination of symbols is not defined in the SRB. In this embodiment, when the SRB is won, it is not necessary that the symbol combination corresponding to the SRB stops on the active line (SRB wins), that is, regardless of the symbol combination stopped in the winning game, A bonus game is started from the next game.

  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 above-mentioned specific role, small role, replay, SRB, and predetermined role). The role lottery means 61 is based on, for example, a random number generation means (hardware random number, etc.) for a role lottery, a random number extraction means for extracting a random number generated by the random number generation means, and a random value extracted by the random number extraction means. And determining means for determining the presence / absence of a winning combination and the winning combination.

  The random number generation means of the role lottery means 61 generates random numbers in a predetermined area (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 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 1BB winning area, it is determined to be 1BB winning, and when it belongs to the non-winning area, it is determined to be non-winning.

  As shown in FIG. 2, for example, during the normal game (non-inside), the role lottery means 61 includes a specific role (1BB and 2BB), a small role (small role 1 to small role 3), replay, and non-winning. Based on the extracted random number value, the presence / absence of winning and the winning combination are determined.

Further, when the SRB is won by the combination lottery means 61, the combination lottery means 61 performs the distribution lottery of SRB1 to SRB5. In the present embodiment, SRB1 to SRB5 are set to 1/5 winning probabilities, and any one SRB is selected using software random numbers.
In addition, a method may be used in which numbers are assigned to five of SRB1 to SRB5, and any of SRB1 to SRB5 is directly selected by lottery.

(Role drawing table)
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 includes a specific combination lottery table 62 for each gaming state.
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.

  Although not shown, the winning area and non-winning area of each role are determined for each set value of the winning rate, and the winning probability of each role shown in FIG. An example is given.

(Means to carry over specific roles)
When the special combination winning means 63 wins the specific combination, the winning combination of the specific combination in the game until the combination of symbols corresponding to the specific combination stops on the active line (until the specific combination wins) is followed. It controls to carry over after a game.
In each of the above-mentioned 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. .

  And as a combination carried over, specific combination (1BB and 2BB) is mentioned. When a specific role is won in the lottery of the role by the role lottery means 61, the combination of the symbols corresponding to the role stops on the active line, and the winning of the role in the game until the winning of the role is followed It is controlled to carry over after the game.

On the other hand, in the lottery of the role by the role lottery means 61, when a role other than the specific role (small role 1 to small role 3, replay, SRB, and predetermined role) is won, the winning combination only in the game. Will be valid and the winnings will not be carried over after the next game. In other words, in a game in which these winning combinations are won, the reel 31 is stopped and controlled so that the winning winning combination can be won, regardless of whether or not the winning winning combination has been won. The rights will disappear.
In the present embodiment, when the winning combination is carried over by the specified role winning carry-over means 63, it is determined by the game at the time of winning the specified role, the small role after the specified role winning, or the non-winning game of replay. The role can be won.

(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.

(Stop position determination table)
The stop position determination table 65 determines the stop position of the reel 31 (design on the effective line when the reel 31 is stopped) based on the position of the reel 31 at the moment when the stop switch 42 is operated.
The stop position determination table 65 is a 1BB table or 2BB table that is used when a special combination 1BB or 2BB is won, and a small combination 1 table or a small combination 2 that is used when winning a small combination 1 to a small combination 3, respectively. A table or small role 3 table, a replay table used when winning a replay, a predetermined role table used when winning a predetermined role, a non-winning table used during non-winning other than a 2BB game, and a CB table used during 2BB gaming Prepare.

  The 1BB table is used on condition that 1BB is won in the game, or 1BB is won in the game before the game and is not won in the game, and the 1BB table is used 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 1 is stopped on the effective line and the combination of symbols corresponding to the role other than 1BB is not stopped on the effective line.

  Here, “within the range of stop control of the reel 31” in the stop position determination table 65 means the movement amount (rotation amount) of the reel 31 from the moment when the stop switch 42 is operated until the reel 31 actually stops. In particular, in the present embodiment, except for the CB table, (1) the movement control amount of the reel 31 from when the stop switch 42 is operated (instant) until the reel 31 is stopped is 5 symbols including the symbol. 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.

In the CB table, (1) the symbol for one symbol from the symbol when the stop switch 42 is operated (instant), or (2) the reel 31 when the stop switch 42 is operated (instant). The stop control time until the stop is within 75 ms.
The CB table of the present embodiment performs the above stop control for all three reels 31, but it is sufficient that the stop control is performed for at least one reel 31, and the remaining reels 31 are other than the CB table. Stop control (the movement control amount when the reel 31 is stopped is within 5 symbols including that symbol, or the stop control time is within 190 ms).

  Furthermore, the 2BB table is used on the condition that 2BB is won in the game, or 2BB 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 2BB is stopped on the effective line and the combination of symbols corresponding to roles other than 2BB is not stopped on the effective line. is there.

  Further, the small role 1 table, the small role 2 table or the small role 3 table is used on condition that the small role 1, the small role 2 or the small role 3 is won in the game, respectively. Within the range, the combination of symbols corresponding to the small role 1, small role 2 or small role 3 is stopped on the active line, and the combination of symbols corresponding to roles other than the small role 1, small role 2 or small role 3 respectively. The combination of symbols at the time when the reel 31 is stopped is determined so as not to stop at the effective line.

  In addition, the replay table is used on the condition that the replay is won in the game, and the combination of symbols corresponding to the replay is stopped on the effective line within the range of the stop control of the reel 31, and the role other than the replay is also supported. 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.

Furthermore, the predetermined combination table is used when a predetermined combination is won in the bonus game of 1BB game, and the combination of symbols corresponding to the predetermined combination is stopped on the effective line within the range of the stop control of the reel 31, and other than the predetermined combination The combination of symbols when the reel 31 is stopped is determined so as not to stop the symbol combination corresponding to the combination.
Further, the non-winning table defines a combination of symbols when the reel 31 is stopped so that the combination of symbols corresponding to any combination does not stop on the active line.

In addition, the CB table is used in a game that is not won for replay in 2BB games, and the symbol combination at the time of stopping the reel 31 is set so as not to stop the symbol combination corresponding to the role other than the small role on the active line. It is determined. Therefore, for the small roles 1 to 3, within the range of the stop control of the reel 31 during the 2BB game (the symbol next to the symbol at the moment when the stop switch 42 is operated (within 75 ms)), The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the small role 3 can be stopped on the effective line.
As described above, the above-described stop control may be performed for at least one reel 31, and the remaining reels 31 are stop controls other than the CB table (stop control within 5 symbols (within 190 ms)). Also good.

  Here, during the 2BB game, the lottery of the small combination is not performed, and it is controlled so that the small combination can be won. In the present embodiment, as shown in FIG. 2, if the “CHERRY” symbol of the left reel 31 stops at the effective line, the small role 3 is independent of the stop symbols of the middle reel 31 and the right reel 31. It is a winning role. Therefore, if the stop switch 42 is operated so that the “cherry” symbol of the left reel 31 stops at the effective line, the small combination 3 can be won regardless of the stop symbol of the middle reel 31 and the right reel 31. .

  In the present embodiment, when the SRB is won, the SRB table is not provided because control for stopping the combination of symbols corresponding to the SRB to the active line is not performed. When the SRB is won, the above non-winning table is used.

  As described above, the reel stop control means 64 uses the stop position determination table 65 to stop the combination of symbols corresponding to any of the combinations on the effective line, and the range of the stop control of the reel 31. The symbols constituting the combination of symbols corresponding to the combination are controlled so as to be stopped on the active line.

(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.

(Specific game control means)
The specific game control means 68 controls the transition from the normal game (internal game) to the specific game (1BB game or 2BB game), the progress of the game during the specific game, the end of the specific game, and the like.

  First, the specific game control means 68 shifts from the normal game to the specific game on condition that the combination of symbols corresponding to the specific combination (1BB or 2BB) has stopped on the active line, that is, the specific combination has won. To control. For example, control is performed so that when a 1BB prize is awarded, the game shifts from a normal game to a 1BB game, and when a 2BB prize is awarded, the game shifts from a normal game to a 2BB game.

Further, when the game shifts to the 1BB game or the 2BB game, the role lottery table 62 is switched to the role lottery table 62 unique to the 1BB game or the 2BB game, respectively.
Furthermore, in the present embodiment, the first specific game control means 68a and the second specific game control means 68b are provided for controlling the progress of the 1BB game or the 2BB game, respectively, when transitioning to the 1BB game or the 2BB game.

The first specific game control means 68a first starts a general game in the 1BB game. As shown in FIG. 2, the winning combinations drawn by the winning lottery means 61 in this general game are the small combination 1 to the small combination 3, replay, and SRB.
Then, when the combination of symbols corresponding to any of the combinations stops on the active line during the general game, the first specific game control means 68a pays out medals corresponding to the combination and wins the SRB. When this happens, the bonus game is started from the next game.

  In the bonus game, the combinations drawn by the combination lottery means 61 are a small combination 1 to a small combination 3 and a predetermined combination as shown in FIG. In the bonus game, the predetermined combination is determined by the combination lottery table 62 so as to win with a high probability of 1 / 1.1.

The bonus game according to the present embodiment is based on the SRB type until the number of winning combinations reaches the specified number of times P (2 or 8 in the present embodiment) or the number of games is the specified number of times (this implementation). It continues until it reaches 12 times in the form.
The first specific game control means 68a ends the bonus game when the number of winning prizes or the number of games in the bonus game reaches a specified number of times, and does not satisfy the BB game end condition. Then, control is performed to return to the general game again.

  Here, when winning the SRB3 and shifting to the bonus game, after the bonus game ends, the game shifts to the general game without RT game in the 1BB game, but when winning other SRBs, After the bonus game is over, the game shifts to a general game that is an RT game during the 1BB game. Therefore, the first specific game control means 68a performs control so that the RT game is executed after the bonus game is ended in accordance with the selected SRB. Also, the RT game count Q is counted, and when the RT game count Q corresponding to the SRB won by the RT game is reached, the RT game is controlled to end.

  The end condition for the 1BB game is determined until the number of medals paid out during the 1BB game reaches a specified number X (360 in this embodiment). Therefore, the first specific game control means 68a counts the number of medals paid out during the 1BB game, and controls to end the 1BB game when the specified number X is reached.

  When the number of paid-out medals during the 1BB game reaches the specified number X, the 1BB game is terminated in the game, and after the next game, the game shifts to a normal game (not in the inside). Therefore, during the 1BB game, not only during the general game but also during the bonus game or the RT game, when the number of medals paid out reaches the specified number X, the 1BB game ends in the game.

  Here, when the payout number of medals in the 1BB game reaches the specified number X during the RT game and the 1BB game is ended, the normal game after the next game may be an RT game, but in this embodiment, When the number of paid-out medals in the 1BB game reaches the specified number X during the RT game and ends the 1BB game, the RT game is controlled to end even if there is a remaining RT game count Q.

  The second specific game control means 68b controls the progress of the 2BB game. When 2BB wins, the second specific game control means 68b controls to execute the 2BB game after the next game. In the 2BB game, as shown in FIG. 2, the role lottery means 61 performs a lottery only for replays. However, in the 2BB game, as described above, the reel 31 is controlled to stop so that the combination of symbols corresponding to the small combinations 1 to 3 that are not drawn by the combination lottery means 61 can be stopped on the effective line (when the replay is won). ), That is, a game in which the winning combination flags of small combination 1 to small combination 3 are turned on. Therefore, during the 2BB game, a small combination can be won according to the skill of the player.

  Further, the end condition of the 2BB game is determined until the number of medals paid out during the 2BB game reaches the specified number Y (253 in this embodiment). Therefore, the second specific game control means 68b counts the number of medals paid out during the 2BB game, and controls to end the 2BB game when the specified number Y is reached.

(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) based on the selected effect pattern. The effect control unit 69 includes an effect pattern selection unit 69a and an effect data table 69b.

  The effect pattern selection unit 69a selects an effect pattern for each game based on the lottery result of the combination by the combination lottery unit 61. In particular, in the present embodiment, a plurality of types of effect patterns are provided in advance, and are stored in the effect pattern data table 69b. The effect pattern selection unit 69a selects one effect pattern by lottery using software random numbers after the combination lottery unit 61 performs 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 a specified role, when winning a small role 1 to 3 (not inside or inside), when winning a replay (not inside or inside), and when not winning (not inside or inside) A plurality of types of effect patterns are provided for each of the above.

  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.).

The slot machine 10 of the present embodiment configured as described above has the following characteristics.
First, in a gaming state where none of the specific roles has been won (inside the normal game), whether 1BB is won (winning probability 1/40) or 2BB is won (winning probability 1/25) It will be in a state to wait. Here, when 2BB is won and won, 2BB games are executed after the next game.

  In this 2BB game, a small role can be awarded according to the skill of the player. For example, if the number of medals paid out for the small role 3 is 10 and almost every game and the small role 3 is awarded, the payout rate will exceed 1 depending on the skill of the player, and as the game progresses, medals The game state can be increased. The 2BB game is continued until the number of payouts reaches the specified number Y = 253, and when the specified number Y is reached, the 2BB game is terminated and the game state is returned to the non-internal game state again. It becomes. Furthermore, in this non-internal game, it is possible to play a game in anticipation of another 2BB win. When 2BB wins and wins again, as described above, 253 payouts are made. The 2BB game can be continued again until it is revealed.

On the other hand, if 1BB is won in the game state in the non-inside of the normal game, after that, 1BB and 2BB are not drawn until the 1BB game ends. If 1BB is won, the game cannot be returned to the non-internal game state again unless the 1BB is won and passed through the 1BB game.
When the game shifts to 1BB game (general game), the expected medal payout number per game based on the small role 1 is set to 15 medal payout numbers for the small role 1.
15 (sheets) x 1/15 (winning probability) = 1 (sheets)
It becomes.

Therefore, if the number of medals inserted in one game is 3, the payout rate based on the small part 1 in 1BB game (general game) is
1/3 ≒ 0.33
It becomes. Even if other combinations are included, in the 1BB game (general game), the payout rate is lower than 1, and the game state is such that the medal decreases as the game progresses.

  In order to escape from such a game state where medals decrease, it is necessary that the number of medal payouts, which is the ending condition of 1BB game, reaches the prescribed number X = 360. This is because when the player enters the 1BB game and the number of medal payouts reaches 360 during the 1BB game, the end condition of the 1BB game is satisfied and the player can return to the non-inside of the normal game. Therefore, during the 1BB game, the game state is such that medals decrease as the game progresses, and the game continues until the number of paid out medals reaches the specified number X.

  In addition, during 1BB game, SRB is drawn (winning probability 1/256). When the SRB is won, a bonus game is executed during the 1BB game from the next game. When shifting to the bonus game, the predetermined winning combination is won and won with a high probability of 1 / 1.1, and the winning combination is continued until the winning number of the winning combination is 2 or 8, or the number of games is 12. Here, it is assumed that the number of medals paid out at the time of winning a predetermined combination is 15 and that a predetermined combination is won every game. At this time, 15 (sheets) × 2 (number of games) = 30 if the prescribed number P of winning combinations is 2 times, 15 (sheets) × 8 (number of games) = 120 medals if 8 times. Will be paid out. Accordingly, winning the SRB during the 1BB game and shifting to the bonus game is preferable because the number of games of the 1BB game can be shortened.

Note that the winning probability of the predetermined role in the bonus game is 1 / 1.1, and when the number of payouts is 15, the expected number of payouts in the bonus game based on the predetermined role is
15 / 1.1 ≒ 13.64 (sheets)
It becomes.
Therefore, if the number of medals inserted in one game of the bonus game is 3, the payout rate based on the predetermined role in the bonus game is
13.64 / 3 = 4.55
It becomes.
That is, the game payout rate exceeds 1, and a game state in which medals increase as the game progresses is achieved.

  As described above, when the game shifts to the 1BB game, the game state is such that the number of medals decreases, and if the prescribed number X of medals are not paid out during the 1BB game, it is not possible to escape from the 1BB game. On the other hand, in the 2BB game, regardless of the lottery of the combination, the player can win a small combination according to the skill and increase the number of medals. As described above, in the 1BB game, the gaming state is disadvantageous to the player, and in the 2BB game, the gaming state advantageous to the player can be achieved.

In addition, during the 1BB game, there may be a case where a winning combination or winning a prize is continuously made to the small part 1. Since the winning probability of the small combination 1 is 1/15, the probability that the small combination 1 wins two consecutive times is 1/225.
On the other hand, if the SRB is won during the general game of 1BB game and the game is shifted to the bonus game, the probability of winning and winning a predetermined combination continuously (at least two consecutive times) increases.

  From the above, from the point of view of the player, when the combination of symbols “BELL”-“BELL”-“BELL” stops on the active line in two games in succession, at this point, 2 It is not known whether the game has been won continuously or the bonus game is being executed (the predetermined role has been won in two consecutive games). For example, when the combination of symbols “BELL”-“BELL”-“BELL” stops on the active line in 3 games and 4 games in succession, it is rare that the small role 1 is won in succession, so it is almost a bonus. It can be determined that the game has been entered (a predetermined role has been continuously won).

In addition, when an SRB other than SRB3 is won and a bonus game is entered, an RT game is subsequently executed.
When the RT game is executed, the winning probability of the replay is greatly increased, so that it is possible to determine whether or not the RT game is executed from the viewpoint of the player.

In this way, when the combination of symbols “BELL”-“BELL”-“BELL” stops on the active line in two consecutive games, it can be expected that the RT game will be executed after the next game. it can.
When the RT game is executed, the game can be continued without reducing the number of medals. This means that the 1BB game end condition (the number of payouts is the prescribed number X) can be reached without reducing the number of medals. In other words, when the RT game is executed, it is preferable that the player can finish the 1BB game without reducing the number of medals than when the RT game is not executed. In particular, the RT game number of games is 500 games. In most cases (when SRB1 or SRB4 is won), the RT game can be continued until the end condition of the 1BB game is reached.

  When an RT game is executed, an effect specific to the RT game may be output. In this way, if the combination of symbols “BELL”-“BELL”-“BELL” stops on the active line for two consecutive games, will the RT game-specific effects be started after the next game? If not, it is possible to notify the player whether or not the RT game is executed (whether or not the SRB has been won).

Next, the game flow in this embodiment will be described. FIG. 3 is a flowchart showing the flow of processing during a normal game.
In step S11 of FIG. 3, the game control means 60 continues to detect whether or not a medal has been inserted. When the insertion of a medal is detected, such as when the bet switch 40 is operated, the process proceeds to step S12. In step S12, the game control means 60 continues to detect whether the start switch 41 is turned on. And when ON is detected, an effective line is decided and it progresses to Step S13. In step S <b> 13, the game control unit 60 controls to start rotation of all the reels 31.

  In the next step S14, the part lottery means 61 performs a part lottery. In step S15, the stop position determination table 65 corresponding to the winning combination is set. In the next step S16, 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 S17, where the reel stop 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 S18, 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 S19. On the other hand, when it is determined that all the reels 31 have not stopped yet, the process returns to step S16.

  In step S19, 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 been won. If so, the process proceeds to step S20. On the other hand, when it is determined that no winning is made, the process proceeds to step S21. In step S20, the payout means 67 performs payout processing according to the winning combination. For example, when a small combination wins, the number of medals corresponding to the winning small combination is paid out, and at the time of replay winning, a process of automatically inserting the number of medals inserted in the game is performed. Then, the process proceeds to step S21.

  In step S21, the stop symbol determining means 66 determines whether or not the specific combination (1BB or 2BB) has won. When it is determined that the specific combination has won, the process proceeds to step S22, and control is performed so as to shift to the specific game corresponding to the specific combination having won. On the other hand, when it is determined that the specific combination has not won, the process according to this flowchart is terminated.

4 and 5 are flowcharts showing the flow of processing during the 1BB game. FIG. 5 is a flowchart following FIG. When 1BB is won and won and the process proceeds to step S22 in FIG. 3, the process proceeds to step S31 and subsequent steps in FIG.
First, in step S31, the first specific game control means 68a performs a general game start process. In the next step S32, the game control means 60 continues to detect whether or not a medal has been inserted, and when it is detected that a medal has been inserted, the process proceeds to step S33. In step S33, 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 S34.

  In step S34, the game control means 60 controls to start the rotation of all the reels 31. In the next step S35, the part lottery means 61 performs a part lottery. Note that the winning combination includes an SRB for shifting to the second game.

  In the next step S36, the stop position determination table 65 corresponding to the winning combination is set. Next, proceeding to step S37, 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 is turned on, the process proceeds to step S38, and the reel stop control means 64 controls the drive of the motor 32 based on the set stop position determination table 65, and the stop that is turned on. Stop control of the reel 31 corresponding to the switch 42 is performed. Next, proceeding to step S39, 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 S40. On the other hand, when it is determined that all the reels 31 are not yet stopped, the process returns to step S37.

  In step S40, the stop symbol determination means 66 determines whether or not any winning combination has been won, that is, whether or not the combination of symbols corresponding to any winning combination has stopped on the active line. When it is determined that the operation has stopped, the process proceeds to step S41. When it is determined that the operation has not been stopped, the process proceeds to step S44. In step S41, the payout means 67 performs a medal payout process corresponding to the winning combination. Then, the process proceeds to step S42.

  In step S42, the first specific game control means 68a performs an update process of the number (total number) of medals paid out during the 1BB game. Specifically, processing for adding the number of medals paid out in step S41 is performed. Next, proceeding to step S43, the first specific game control means 68a determines whether or not the number of medals to be paid out in 1BB game has reached a specified number X (360 in this embodiment) which is the end condition of 1BB game. Determine. When it is determined that the specified number X has been reached, the first specific game control means 68a controls to end the 1BB game. On the other hand, when it is determined that the specified number X has not yet been reached, the process proceeds to step S44.

  When the process proceeds from step S40 or step S43 to step S44, the first specific game control means 68a determines whether or not the SRB is won in the game. When it is determined that the game has not been won, control is returned to step S32 to continue the general game. On the other hand, when it is determined in step S44 that the SRB has been won, the process proceeds to step S45, and the first specific game control means 68a determines whether the selected SRB is an SRB with an RT game. When it is determined that the SRB has an RT game, the process proceeds to step S46, and the RT flag is turned on. Then, the process proceeds to step S51. On the other hand, if it is determined in step S45 that the SRB is not an RT game, the process proceeds to step S51.

  In step S51, the first specific game control means 68a performs a bonus game start process. Specifically, an initial value is set for the (remaining) number of games Z of the bonus game (in this embodiment, an initial value of the number of games Z = 12), and an initial value is set for the prescribed number P of winning combinations. (In this embodiment, the initial value of the prescribed number P = 2 or 8 depending on the type of SRB).

  In the next step S52, the game control means 60 continues to detect whether or not a medal has been inserted. When it is determined that a medal has been inserted, the game control means 60 proceeds to step S53. In step S53, 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 S54. In step S54, the game control means 60 controls to start the rotation of each reel 31. In the next step S55, the first specific game control means 68a subtracts 1 from the number of games Z of the bonus game (Z = Z-1). In the next step S56, the part lottery means 61 performs a part lottery.

  In the next step S57, the stop position determination table 65 corresponding to the winning combination is set. Next, proceeding to step S58, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when it is detected, the process proceeds to step S59. In step S59, the reel stop control means 64 determines the stop position of the reel 31 based on the timing when the stop switch 42 is operated according to the set stop position determination table 65, and the reel is set at the determined position. 31 is controlled to stop. Then, the process proceeds to step S60.

  In step S60, the game control means 60 determines whether or not all the reels 31 are stopped. When it is determined that all the reels 31 are stopped, the process proceeds to step S61. On the other hand, when it is determined in step S60 that all the reels 31 are not stopped, the process returns to step S58.

  In step S61, the stop symbol determination means 66 determines whether or not the combination of symbols corresponding to any combination has stopped on the active line (whether any combination has won a prize). When it is determined that the winning combination has been won, the process proceeds to step S62. On the other hand, when it is determined that no winning combination has been won, the process proceeds to step S66.

In step S62, the payout means 67 pays out medals corresponding to the winning combination, and proceeds to step S63. In step S63, the first specific game control means 68a performs a process of updating the number of medals paid out during 1BB game (total number), and proceeds to step S64.
In step S64, the first specific game control means 68a subtracts 1 from the prescribed number P of winning combinations for the bonus game (P = P-1). Then, the process proceeds to step S65.

  In step S65, the first specific game control means 68a determines whether or not the number of medals paid out, which is the end condition of the 1BB game, has reached the specified number X. When it is determined that the specified number X has been reached, the first specific game control means 68a controls to end the 1BB game. On the other hand, when it is determined that the specified number X has not yet been reached, the process proceeds to step S66.

  In step S66, the first specific game control means 68a determines whether or not a bonus game end condition is satisfied. In the present embodiment, the bonus game end condition is satisfied when either one of the remaining number of games Z is 0 or the specified number P of winning combinations in the bonus game is 0 is satisfied. It is determined that

When it is determined that the end condition is satisfied, the process proceeds to step S67. On the other hand, when it is determined that the end condition is not yet satisfied, the process returns to step S52, and the first specific game control means 68a controls to continue the bonus game.
In step S67, it is determined whether or not the RT flag is turned on. When the RT flag is turned on in step S46 described above, it is determined that the flag is turned on. When it is determined that the RT flag is on, the process proceeds to step S68, and the RT game is set in the general game after the next game. And it progresses to step S31 and it controls to resume a general game. On the other hand, if it is determined in step S67 that the RT flag is not on, the process proceeds to step S31 without performing the process of step S68.

FIG. 6 is a flowchart showing the flow of processing in the 2BB game. When the process shifts to the 2BB game in step S22 of FIG. 3, the process proceeds to the process after step S71 of FIG. 6 after the next game.
First, in step S71, the game control means 60 continues to detect whether or not a medal has been inserted, and when it is detected that a medal has been inserted, the process proceeds to step S72. In step S72, 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 S73.

In step S <b> 73, the game control means 60 controls to start the rotation of all the reels 31. In the next step S74, the part lottery means 61 performs a part lottery. In addition, only the replay is a winning combination.
In the next step S75, it is determined whether or not the replay is won in the lottery in step S74. If it is determined that the replay is not won, the process proceeds to step S76, the CB table is set as the stop position determination table 65 used in the game, and the process proceeds to step S78. On the other hand, when it is determined that the replay is won, the process proceeds to step S77, the replay table is set as the stop position determination table 65 used in the game, and the process proceeds to step S78.

  In step S78, 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 S79, where the reel stop control means 64 controls the drive of the motor 32 based on the set stop position determination table 65, and the stop that has been turned on.
