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 means for comprehensively controlling the entire slot machine 10 including the progress and effects of the game of the slot machine 10, and includes lottery of the role, drive control of the reel 31, and payout at the time of winning. It controls the progress of the game and the output of the production. The game control means 60 is provided on the control board, and is a CPU that performs calculations, a ROM that stores programs necessary for the progress of the game, data for production, and the like, and when the CPU performs various controls. RAM etc. which memorize | store the data etc. which were taken in are temporarily stored.

(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, 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.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied so as to perform various effects during the game.
Furthermore, the image display device 23 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 according to the number of medals inserted by the player.
Here, in the present embodiment, the “effective line” is a line for winning a combination when a combination of symbols corresponding to any combination stops on the line.

  On the other hand, the “invalid line” is generated when the number of inserted medals is one or two, and is a line that is not set as an effective line among the symbol combination lines, and a combination of symbols corresponding to any of the combinations. Even if the line is stopped, a profit according to the combination (medal payout etc.) is not performed. In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

  Here, in the slot machine, there are a case where the player can select the number of medals inserted in one game and a case where the number of medals inserted is preset to one. In the former case, for example, the player can select from 1 to 3 medals. When the number of medals inserted is 1, the horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbol combination lines are set as invalid lines.

When the number of inserted medals is 2, the horizontal, middle, upper and lower symbol combination lines (total of three) are set as valid lines, and the other two symbol combination lines are set as invalid lines. The Furthermore, when the number of inserted medals is 3, all the symbol combination lines (a total of 5) are set as valid lines and there are no invalid lines.
On the other hand, in the latter case, the number of medals inserted in one game is fixed at, for example, three. In this embodiment, the latter case is set (the number of inserted medals is fixed at 3).

(Role)
FIG. 2 is a diagram showing the types of combinations, combinations of symbols, and winning probabilities in the present embodiment. As types of combinations in this embodiment, a specific combination, a small combination, a replay, a transition combination, and a predetermined combination are provided.
The specific combination is a combination for executing a specific game. In this embodiment, the specific combination includes BB (first specific combination), SB (second specific combination), and RB (third specific combination). Three types are provided.

  BB is a role that shifts to a BB game (first specific game) that is one of the specific games, and SB is a role that shifts to SB game (second specific game) that is another one of the specific games. Yes, the RB is a role for shifting to the RB game (third specific game) which is still another specific game.

  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. Here, the small combination 1 is a combination corresponding to the specific small combination in the present invention, and as shown in FIG. 2, the winning combination has a high winning probability during the SB game.

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.
The SRB is a transitional role, which is a lottery during the general game of the BB game, and is a role for shifting from the general game to the bonus game during the BB game. That is, when the SRB is won and won during the general game of the BB game, the game shifts from the general game to the bonus game.
Furthermore, the predetermined combination is a combination in which a predetermined number of medals are paid out in the same manner as the small combination.

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, a special combination (BB, SB and RB), three types of small combinations (small combination 1, small combination 2 and small combination 3), and a replay are provided as a combination during a normal game (non-inside). It has been.
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 BB game is provided with a general game and a bonus game. As shown in FIG. 2, there are three types of small roles (small role 1, small role 2) as the role during the general game of the BB game. And a small combination 3), a replay and an SRB (transitional combination).
Further, the bonus game of BB game and the RB game are equal games, and are games in which a predetermined role is mainly won and won.

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. .
Among the specific combinations, BB and RB can be cited as carry-overs. When winning a winning combination in the drawing by the drawing lottery means 61, which will be described later, the combination of symbols corresponding to the winning combination is stopped on the active line, and in the game until the winning of the winning combination, It is controlled to carry over the winning after the next game.

  On the other hand, when a winning combination other than BB and RB (SB, small combination 1 to small combination 3, replay, SRB, and predetermined combination) is won in the combination drawing by the combination lottery means 61, only in the game. The winning combination will be valid and will not be carried over after the next game. That is, in a game in which these winning combinations are won, the reel 31 is controlled to stop the winning combination so that the winning combination can be won at the end of the game regardless of whether or not the winning combination has been won. The rights will disappear.

  Further, as shown in FIG. 2, the combination of symbols of the reels 31 corresponding to the above various types of roles is determined in advance, and when all the reels 31 are stopped, it corresponds to any of the predetermined roles. When the combination of symbols stops on the active line and the winning combination is won, a predetermined number of medals are paid out, although not shown in FIG.

  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 (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 BB winning area, it is determined as BB winning, and when it belongs to the non-winning area, it is determined as non-winning.

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

(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)
In the game until the combination of symbols corresponding to the specific combination stops on the active line (until the specific combination wins) when the special combination winning means 63 is selected as BB or RB among the specific combinations, It controls to carry on the winning of a specific role after the next game.
In the present embodiment, when the winning combination is carried over by the specified role winning carry-over means 63, a game at the time of winning the specified role, or a small role, replay or non-winning game of the predetermined role after the specified role winning, The specific role can win a prize.

(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.

  The reel stop control means 64 controls the stop of the reel 31 so that the combination of symbols corresponding to the small role 1 is stopped on the effective line, for example, in a game won by the small role 1, and corresponds to a role other than the small role 1 The reel 31 is controlled to stop so that the symbol combination to be stopped is not stopped on the effective line.

(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 includes a BB table, an SB table or an RB table used when winning a specific combination BB, SB or RB, respectively, a small combination 1 table used when winning a small combination 1 to a small combination 3, A small role 2 table or a small role 3 table, a replay table used when winning a replay, an SRB table used when winning an SRB, a predetermined role table used when winning a predetermined role, and a non-winning table used when not winning .

  The BB table is used on condition that the BB is won in the game, or the BB is won in the game before the game and the game is not won. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to is stopped on the effective line and the combination of symbols corresponding to the role other than BB 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 this embodiment, (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 within 5 symbols, or (2) the stop switch 42 is The stop control time from when it is operated (instant) until the reel 31 is stopped is within 190 ms.

  In addition, the RB table is used on the condition that the RB is won in the game, or the RB is won in the game before the game and the game is not won. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to RB is stopped on the effective line and the combination of symbols corresponding to roles other than RB is not stopped on the effective line. .

  Furthermore, the SB table is used on the condition that SB is won in the game, and within the range of the stop control of the reel 31, the combination of symbols corresponding to SB is stopped on the effective line, and symbols other than SB are also displayed. The combination of symbols when the reel 31 is stopped is determined so that the combination is not stopped on the effective line.

  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 SRB table is used when the SRB is won in the first game of the BB game, and the combination of symbols corresponding to the SRB is stopped on the effective line within the range of the stop control of the reel 31 and is used for other than the SRB. The combination of symbols when the reel 31 is stopped is determined so that the corresponding symbol combination is not stopped on the effective line.

Further, the predetermined combination table is used when a predetermined combination is won, 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 the symbols corresponding to the combinations other than the predetermined combination are displayed. The combination of symbols when the reel 31 is stopped is determined so that the combination is not stopped on the effective line.
In addition, 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 does not stop on the active line.

  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.

  FIG. 3 is a plan view showing a symbol arrangement on the outer peripheral surface of each reel 31 in the present embodiment. FIG. 3 shows only a part of the symbol arrangement, and a predetermined symbol is also displayed in a blank part in the drawing, but the description is omitted here.

As shown in FIG. 3, on each reel 31, 21 symbols are arranged at equal intervals.
Further, all the symbols of “bell” are arranged on each reel 31 at intervals of 5 symbols or less. Accordingly, symbols of “bell” are arranged on the reel 31 at intervals within the range of stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). Thereby, when winning the winning combination 1, it is possible to always control the winning combination of the winning combination 1 to stop on the active line.

  On the other hand, when “bells” which are symbols constituting the small role 1 are arranged at intervals exceeding the range of the stop control of the reel 31 (for example, 6 symbol intervals), when the small role 1 is won, Unless the stop switch 42 is operated at a position where the “bell” can be stopped on the active line, the “bell” which is the symbol constituting the winning combination 1 cannot be stopped on the active line. This means “within the range of reel 31 stop control”.

  As shown in FIG. 3, in the right reel 31, “red 7” that is a symbol constituting the BB and “black 7” that constitutes the RB are arranged adjacent to each other. That is, when “red 7”-“red 7”-“(rotating)” is stopped on any effective line for the left reel 31 and the middle reel 31, the right reel 31 is set to the effective line. If the stop switch 42 is operated at the moment when the symbols from No. 6 to No. 9 are located, No. 5 “Black 7” or No. 6 “Red 7” of the right reel 31 can be stopped on the effective line. it can.

  That is, when either BB or RB is won, if the stop switch 42 is operated as described above, the combination of symbols corresponding to the winning combination can be stopped on the active line. . If constituted in this way, if it is assumed that the stop switch 42 is operated in order of middle left and right, the player cannot know which of BB or RB is won until the right reel 31 is stopped. The winning combination is not known until the last stop switch 42 is operated.

  Although not shown in FIG. 3, in the left reel 31, one of “red 7” and “black 7” is arranged at intervals of 5 symbols or less. Furthermore, in all the reels 31, the symbols “R” are all arranged at intervals within 5 symbols. Thereby, at the time of winning of SB, replay, SRB, and predetermined combination, the combination of symbols corresponding to each of the selected SB, replay, SRB, and predetermined combination can be stopped on the effective line. Therefore, for example, when SB or SRB is won, the winning is not carried over after the next game, but the winning game can always be won.

(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 (BB game, SB game or RB game), the progress of the game during the specific game, the end of the specific game, etc. It is.

  First, the specific game control means 68 shifts from the normal game to the specific game on the condition that the combination of symbols corresponding to the specific combination (BB, SB or RB) is stopped on the active line, that is, the specific combination wins. Control to do. For example, control is performed so that when a BB wins, the normal game shifts to the BB game, when an SB wins, the normal game shifts to the SB game, and when the RB wins, the normal game shifts to the RB game.

Further, when transitioning to BB game, SB game or RB game, the role lottery table 62 is switched to the role lottery table 62 specific to the BB game, SB game or RB game, respectively.
Furthermore, in this embodiment, when the BB game, SB game or RB game is entered, the first specific game control means 68a and the second specific game for controlling the progress of these BB game, SB game or RB game, respectively. Control means 68b and third specific game control means 68c are provided.

The first specific game control means 68a first starts a general game in the BB 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, the replay, the SRB, and the predetermined combination.
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 corresponds to the SRB. When the combination of symbols to be stopped stops on the active line, the game is shifted from the general game to the bonus game (in the present embodiment, the same as the RB game (third specific game)).

  Also in the bonus game, control is performed so that three medals are accepted as in the general game. In addition, as shown in FIG. 2, the winning combinations drawn by the winning lottery means 61 in the bonus game are the small combination 1 to the small combination 3 and the predetermined combination. In the bonus game, the predetermined combination is determined by the combination lottery table 62 so that the predetermined combination is won with a high probability of 1 / 1.09.

In the bonus game of the present embodiment, until the predetermined number of winnings of the predetermined role reaches the specified number of times (8 times in the present embodiment) or until the number of games reaches the specified number of times (in this embodiment, 12 times) Will continue.
The first specific game control means 68a terminates the bonus game when the number of winnings or the number of games of the predetermined role in the bonus game reaches the 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, the end condition of the BB game is determined until the payout number of medals during the BB game reaches a predetermined number (480 in this embodiment). Therefore, the first specific game control means 68a counts the number of medals paid out during the BB game, and controls to end the BB game when the predetermined number is reached.

  The second specific game control means 68b controls the progress of the SB game. When the SB wins, the second specific game control means 68b controls to execute the SB game only for the next game (1 game). In the SB game, as shown in FIG. 2, the role lottery means 61 performs a lottery for a role other than the SRB. However, in the SB game, the winning probability of the small role 1 is set higher from 1 / 1.63 in the normal game to 1 / 1.85. In the present embodiment, even when a replay is won and won during an SB game, control is performed so that the SB game is terminated and the normal game is returned to that game.

Furthermore, the third specific game control means 68c controls the progress of the RB game. In the RB game, a bonus game in the above-mentioned BB game is played until one set, that is, until the number of winnings or games of a predetermined role reaches each specified number of times.
Therefore, in the RB game, the third specific game control means 68c continues the RB game until the predetermined number of winnings or the number of games reaches the specified number, and the predetermined number of winnings or the number of games reaches the specified number. If it is, it is determined that the RB game end condition is satisfied, and control is performed to end the RB game.

(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.).

  For example, in one of the production patterns, when the start switch 41 is operated, a specific sound is output from the speaker 22, and when the third stop switch 42 is operated, the lamp 21 ( And a specific image is displayed on the image display device 23 every time the reels 31 are stopped.

In addition, a specific effect pattern is provided as one of the effect patterns. The specific effect pattern is an effect pattern that is selected when the number of medals paid out during the BB game becomes close to 480, which is the number of BB game end conditions. That is, it is an effect pattern for outputting an effect (a sign effect) that notifies the player that the end of the BB game is near.
In the present embodiment, the specific effect pattern is selected when the number of medals paid out during the BB game reaches 450, that is, when the BB game ends with the remaining 30 payouts.

  When a specific effect pattern is selected, it is sufficient to output the effect in at least one game. After selecting the specific effect pattern, the display of the remaining payout number, etc. is updated in the game until the end of the BB game. However, the output based on the specific effect pattern may be continuously output.

  Specific effects include blinking the lamp 21 in a specific pattern, outputting a specific sound from the speaker 22, and displaying a specific image on the image display device 23 (for example, “remaining payout number ○ Image display etc.) ”. However, the effect based on the specific effect pattern does not need to be output using all of the lamp 21, the speaker 22, and the image display device 23, and may be output from at least one effect output device.

The slot machine 10 of the present embodiment configured as described above has the following characteristics.
First, in a game state in which no specific combination is won (in the non-inside of the normal game), a state is waited for whether to win BB, win SB, or win RB.
Here, considering RB, the specific combination is either winning BB or winning SB. The SB is set so as to be won with a probability of 1 / 3.16 (approximately once every 3 games) in the non-inside of the normal game. When SB is won and won, in the next game, SB game is executed for only one game. In this SB game, the small role 1 is won and won with a high probability of 1 / 1.85. In addition, the SB game is ended in one game and the game state is returned to the non-internal game state again, but the SB is once again won at a rate of about once every three games.

Therefore, the expected medal payout number based on the small role 1 in the non-inside of the normal game is 15 if the payout number at the time of winning the small role 1 is 15
15 / 11.63 + 15 / (3.16 × 1.85) ≈3.86 (sheets)
It becomes.

Therefore, if the number of medals inserted in one game is three, the payout rate (expected medal payout number / medal insertion number) based on the small role 1 in the non-inside of the normal game is
3.86 / 3 ≒ 1.29
It becomes. That is, only the small role 1 has a payout rate exceeding 1, and a gaming state in which medals increase as the game progresses is achieved.
In this way, during the non-inside of the normal game, SBs can win and win at a rate of about once every 3 games, and can shift to SB games, so that medals can be increased.

On the other hand, if the BB is won in the non-internal gaming state of the normal game, after that, the BB, SB and RB (excluding the SRB) are not drawn until the BB game is finished. If a BB is won, the game state cannot be returned to a non-internal game state unless the BB is won and passed through the BB game.
And when it shifts to BB game (general game), the medal payout number expected value based on the small role 1 is
15 / 11.63 ≒ 1.29 (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 the BB game (general game) is
1.29 / 3≈0.43
It becomes. Even if other combinations are included, in the BB game (general game), the payout rate is lower than 1, and the game state is such that the number of medals decreases as the game progresses.

  In order to escape from such a game state where medals decrease, it is necessary that the number of medals paid out, which is a BB game end condition, reaches 480. This is because when the player enters the BB game and the number of paid-out medals reaches 480 during the BB game, the BB game end condition is satisfied and the player can return to the non-inside of the normal game. Accordingly, during the BB game, the game state is such that medals decrease as the game progresses and continues until the number of paid out medals reaches 480.

  During the BB game, SRB is drawn. When the SRB is won and won, a bonus game is executed during the BB game. When shifting to the bonus game, the predetermined combination wins and wins with a high probability of 1 / 1.09, and continues until the predetermined combination wins 8 times (or 12 games). Here, assuming that the number of medals to be paid out at the time of winning a predetermined role is nine, if shifting to a bonus game, one bonus game (almost 8 games) and 9 (sheets) × 8 (number of games) by a predetermined role. ) = 72 medals will be paid out. As a result, winning and winning SRB during BB games and shifting to a bonus game are preferable because the number of BB games can be reduced.

As described above, when the game shifts to BB game, it becomes a game state in which medals are reduced, and when the BB game ends and the normal game is not inside, the SB frequently wins and wins until the BB wins and the number of acquired medals is increased. A gaming state that can be increased.
Thereby, a wave can be given to a payout rate using BB game and non-inside of normal game.

In addition, when an RB is won and won during a non-inside of the normal game, the RB game is executed until the predetermined number of winnings reaches 8 times or the number of games reaches 12 times, similarly to the above SRB. Since the winning probability of the predetermined role in RB game is 1 / 1.09 and the number of payouts is 9, the expected number of payouts in RB game based on this predetermined role and small role 1 is
15 / 11.63 + 9 / 1.09 ≒ 9.55 (sheets)
It becomes.

Therefore, if the number of medals inserted in one game is three, the payout rate based on the predetermined combination and small combination 1 in RB game is:
9.55 / 3≈3.18
It becomes.
That is, the game payout rate exceeds 1, and a game state in which medals increase as the game progresses is achieved.

Next, the game flow in this embodiment will be described. FIG. 4 is a flowchart showing the flow of processing during a normal game.
In step S11 of FIG. 4, 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 determination means 66 determines whether or not the specific combination (BB, SB or RB) 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.

5 and 6 are flowcharts showing the flow of processing during the BB game. FIG. 6 is a flowchart following FIG. When BB is won and won and the process proceeds to step S22 in FIG. 4, 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 it has stopped, the process proceeds to step S41, and when it is determined that it has not stopped, the process returns to step S32 to continue the general game. 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 a process of updating the number of medals to be paid out (total number) during the BB 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 paid out in the BB game has reached the end condition number M of BB games (480 in this embodiment). When it is determined that the ending condition number M has been reached, the first specific game control means 68a controls to end the BB game. On the other hand, when it is determined that the end condition number M has not yet been reached, the process proceeds to step S44.

In step S44, the first specific game control means 68a determines whether or not the number of medals paid out has reached N (= 450). When it is determined that the number of payouts has reached N, the process proceeds to step S45, where the effect control means 69 selects a specific effect pattern and, based on the specific effect pattern, the effect that the number of payouts has reached N Control is performed to output (an effect that displays the number of remaining payouts up to 480). Then, the process proceeds to step S46. On the other hand, when it is determined in step S44 that the number of payouts has not reached N, the process proceeds to step S46.
In step S46, the stop symbol determination means 66 determines whether or not the SRB has won in the game. When it is determined that the SRB has won, the process proceeds to step S51 (FIG. 6) and subsequent steps. On the other hand, when it is determined that the SRB has not won, the process returns to step S32 and control is performed so as to continue the general game.

  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 X of the bonus game (in this embodiment, an initial value of the number of games X = 12), and an initial value is set for the (remaining) number of winnings Y ( In the present embodiment, the initial value of the number of winning times Y = 8).

  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 X of the bonus game (X = X-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 S68.

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 updates the payout number (total number) of medals in the BB game, and proceeds to step S64.
In step S64, the first specific game control means 68a subtracts 1 from the number Y of winning a bonus game (Y = Y-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 has reached the end condition number M. When it is determined that the ending condition number M has been reached, the first specific game control means 68a controls to end the BB game. On the other hand, when it is determined that the end condition number M 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 the number of medals paid out has reached N. When it is determined that the number of payouts has reached N, the process proceeds to step S67, where the effect control means 69 selects a specific effect pattern and, based on the specific effect pattern, the effect that the number of payouts has reached N Is controlled to output. Then, the process proceeds to step S68. On the other hand, when it is determined in step S66 that the number of payouts has not reached N, the process proceeds to step S68.

  In step S68, the first specific game control means 68a determines whether or not a bonus game end condition is satisfied. In the present embodiment, it is determined that the bonus game end condition is satisfied when the predetermined number of winnings in the bonus game is 8 or the number of games is 12.

  When it is determined that the end condition is satisfied, the process returns to step 31, and control is performed so that the general game of the BB game is started again. On the other hand, if it is determined in step S68 that it is not yet satisfied, the process returns to step S52, and the first specific game control means 68a continues the bonus game.

  In addition, when it transfers to RB game by FIG.4 S22, RB game will be started from the next game, but illustration by a flowchart is abbreviate | omitted about the flow of RB game. When the RB game is entered, the processing from step S51 onward in FIG. 6 is performed. However, in the RB game, the processing of step S65 to step S67 is not performed. In the RB game, when at least one of X = 0 or Y = 0 is satisfied in step S68, the RB game is controlled to end.

  Also, when the SB game is entered in step S22 of FIG. 4, the SB game is executed in the next game (1 game), but the process flow of the SB game is the same as the process flow of the normal game. The illustration by is omitted. As shown in FIG. 2, in the SB game, a special combination (BB, RB and SB) is also drawn, and if any specific combination is won, in the next game, the BB game, the RB game or the SB game ( In this case, another SB game) is executed. Further, when replay is won in the SB game, the next game shifts to the normal game instead of the SB game.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications such as the following are possible.
(1) In this embodiment, medals are used as game media. However, the present invention can also be applied to slot machines that use game media other than medals, such as game balls.

  (2) In the flowchart of this embodiment, during the BB game, at the end of the game, it is determined whether or not the number of payouts has reached N. When it is determined that the game has reached, a specific effect pattern is selected, An effect based on the specific effect pattern is output. However, not limited to this, it is determined whether or not the number of payouts has reached N at the start of the game, and when it is determined that the number of payouts has reached N, a specific effect pattern is selected and a start switch When 41 is operated, an effect based on the specific effect pattern may be output.
