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 in order to perform various effects during the game.
Furthermore, the image display device 23 includes a liquid crystal image display device, a dot display, and the like, and displays various effect images, 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, an effective line and an invalid line are set from the five 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 (such as paying out medals). In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

Here, in this embodiment, the number of medals inserted in one game may be one or three. When the number of medals inserted is 1, the horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbol combination lines are set as invalid lines. 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.
Although not planned in the present embodiment, when the number of inserted medals is two, the horizontal middle, upper and lower symbol combination lines (three in total) are set as effective lines and the other two The symbol combination line is set as an invalid line.

(Role)
FIG. 2 is a diagram showing the types of winning combinations and winning probabilities in the present embodiment. As types of the combination in this embodiment, 1BB, 2BB, RB, CB, SB, replay, and small combination are provided.
Here, CB is a role corresponding to the first specific role in the present invention, and is a role to be transferred to the CB game (first specific game). Further, 2BB is a role corresponding to the second specific role in the present invention, and is a role to be shifted to the 2BB game (second specific game). Furthermore, 1BB is a role corresponding to the third specific role in the present invention, and is a role to be transferred to the 1BB game (third specific game). Furthermore, RB and SB are roles corresponding to the fourth specific combination in the present invention, and are transferred to the RB game and the SB game (fourth specific game), respectively.

Furthermore, the replay is a replaying role in which the next game (replaying) can be performed without inserting medals. Depending on the game state, there are both cases where replay can be performed while maintaining the number of medals inserted in the game, and cases where replay can be performed with a number of medals different from the number of medals inserted in the game.
Further, the small combination is a combination in which a predetermined number of medals are paid out, and in this embodiment, three types of small combination 1 to small combination 3 are provided. The small combination 1 is a combination corresponding to the specific small combination in the present invention.

Further, the combination is determined for each gaming state.
For example, during 1BB game, only a small combination 1 to a small combination 3 are drawn. This gaming state is the same as during RB gaming.
Here, in the conventional slot machine, when a transition is made to a 1BB game, a general game is played first, and when a transition role (SRB) for shifting to an RB game (bonus game) is won and won in this general game, The mainstream is that RB games are executed from games. On the other hand, if 1BB of this embodiment wins, RB game will be performed after the next game. When the RB game end condition is satisfied, the RB game is once ended, but at the start of the next game, the RB game is started again. In this way, in the 1BB game, the RB game continues to be executed until the end condition for the 1BB game is satisfied.

  During the above 1BB game, the number of medals inserted is set to 3 and the game is set so that the game cannot be performed with 1 or 2 medals. The same applies to normal games, 2BB games, and RB games.

The 2BB game is provided with a general game and a CB game, and as shown in FIG. 2, RB, CB, SB, replay, and a small role are provided as a role in the general game of the 2BB game. Yes.
If CB is won in this 2BB game, in the next game, only one game will be played. In the CB game of the present embodiment, the game is performed with one medal inserted. And during the CB game, the small role is not drawn. However, during the CB game, it is controlled so that the small role can be stopped on the active line by the skill of the player regardless of the lottery of the role.

Here, in FIG. 2, a winning combination is shown during the CB game. However, when the CB game is won and won during the normal game and the game moves to the CB game, as shown in FIG. 2, 1BB, 2BB , RB, CB and SB are drawn. On the other hand, when winning and winning a CB during 2BB game and shifting to CB game, 1BB and 2BB lottery are not performed in that CB game. However, lottery of RB, CB and SB is performed.
Further, the SB game is a game that is performed with one medal inserted as in the CB game.

Furthermore, although not shown in FIG. 2, the combination of the 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.
The CB is provided with a combination of three types of symbols. This point will be described later.

  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 (1BB, 2BB, RB, CB, SB, replay, and small role described above). 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, the role lottery means 61 is selected based on the random number value extracted from 1BB, 2BB, RB, CB, SB, replay, small role, and non-winning. The presence or absence and winning combination are determined.

Here, as described above, the combination of three types of symbols is provided in advance in the CB. In the present embodiment, the CB winning area is divided into three, and different combinations of symbols are assigned. Thereby, at the time of winning CB, any one kind of symbol combination is determined. For example, in FIG. 2, the fact that the winning area of the CB is 1/5 in the normal game and the 2BB game means that there are three 1/15 winning areas. Similarly, in the CB game and the SB game, the winning area of CB is 3/65536, which means that there are three 1/65536 winning areas.
However, the present invention is not limited to this, and there may be one CB winning area, and after winning the CB, any one type of symbol combination may be determined by lottery.

(Role drawing table)
As shown in FIG. 2, the combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. The combination lottery table 62 includes a specific combination lottery table 62 for each gaming state (during normal gaming, during 1BB gaming, during 2BB gaming, during RB gaming, during CB gaming, and during SB gaming).
Each combination lottery table 62 has a predetermined range of lottery areas. The lottery area is divided into a winning area and a non-winning area for each combination, and the winning combinations are determined in advance. It is set to a predetermined ratio so as to be a probability.

  In addition, the winning probability of each combination is determined when the number of inserted medals is one and when the number is three. As shown in FIG. 2, during the normal game, during the 1BB game, during the 2BB game, and during the RB game, only when the number of inserted medals is three. Further, during the CB game and the SB game, it is determined only when the number of inserted medals is one. The reason for this setting is to change the winning combination probability for each gaming state and the number of inserted medals. For example, the winning probability of 2BB is 1/65536 when the number of inserted medals is 3, but is 1/3 when the number of inserted medals is 1. That is, 2BB is a role having a different winning probability depending on the number of medals inserted.

  Although not shown, the winning area and non-winning area of each role are determined for each set value of the payout rate (six levels of setting 1 to setting 6), and the winning probability of each role shown in FIG. One example when the set value of the payout rate is determined is given.

(Means to carry over winning)
The winning carry-over means 63, when winning 1BB, 2BB, and RB, in the game until the combination of symbols corresponding to each winning combination stops on the active line (until the winning combination wins) It is controlled to carry over the winning of the game after the next game.
As described above, in this embodiment, when a combination of symbols corresponding to a role does not stop on the active line in the game won for the role, a role that is carried over after the next game and a role that is not carried over are determined. It has been.
And as a part carried over, 1BB, 2BB, and RB are mentioned. When winning a winning combination, the combination of symbols corresponding to the winning combination stops on the active line, and in the game until the winning of the winning combination is controlled, the winning combination of the winning combination is carried over from the next game onwards. .

  On the other hand, when a winning combination other than 1BB, 2BB and RB is won in the winning lottery by the winning lottery means 61, the winning combination is valid only in the game, and the winning is not 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.

  Further, in the present embodiment, in a gaming state in which none of 1BB, 2BB, and RB is won (during normal game), a lottery of a combination including these combinations is performed, but 1BB, 2BB, or RB If any of the above is won, a lottery of the roles will be performed excluding these roles.

(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 used at the time of winning 1BB, a 2BB table used at the time of winning 2BB, an RB table used at the time of winning RB, a CB table used at the time of winning CB, and an SB used at the time of winning SB. Table, replay table used at the time of replay selection, small role 1 table, small role 2 table or small role 3 table used at the time of winning each of the small roles 1 to 3, used at the time of non-winning except during the CB game A non-winning table and a CB gaming table used at the time of non-winning CB gaming are provided.

  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 this embodiment, except during the CB game, (1) the movement control amount of the reel 31 from when the stop switch 42 is operated (momentary) until the reel 31 is stopped is 5 including the symbol. Within the symbol, or (2) the stop control time from when the stop switch 42 is operated (momentary) until the reel 31 is stopped is within 190 ms.

In addition, during CB game (when the winning combination is not won), for the right reel 31, (1) a symbol whose movement is controlled by one symbol from the symbol when the stop switch 42 is operated (moment), or (2) The stop control time from when the stop switch 42 is operated (momentary) until the reel 31 is stopped is within 75 ms.
Furthermore, the left reel 31 and the middle reel 31 during the CB game are the same as those other than during the CB game.

  Further, the 2BB table is used on 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 the role other than 2BB is not stopped on the effective line. .

  In addition, 2BB symbols are arranged on each reel 31 at intervals of 5 symbols or less. Thus, regardless of the position of the reel 31 at which the stop switch 42 is operated, the symbol combination corresponding to 2BB can be stopped (winned) at the time of winning of 2BB. That is, during a CB game or an SB game, 2BB is won with a probability of 1/3, but when 2BB is won, control is performed so that 2BB always wins.

  Furthermore, 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, and the range of the reel 31 stop control is used. 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. is there.

  Further, the CB table is used at the time of winning the CB, and within the range of the reel 31 stop control, the combination of symbols corresponding to the CB is stopped on the effective line, and the combination of symbols corresponding to the role other than the CB is activated The combination of symbols when the reel 31 is stopped is determined so that the reel 31 is not stopped.

  Here, when winning the CB, as described above, any one of the three types of symbol combinations is determined, but only the symbol of the left reel 31 is the combination of the three types of symbols. Is different. For example, the combination of three types of symbols is set to “A”-“X”-“X”, “B”-“X”-“X”, and “C”-“X”-“X”. Is mentioned. The three types of symbols “A”, “B”, and “C” of the left reel 31 are arranged at intervals of 7 symbols. Thereby, when stop control within 5 symbols is executed for the left reel 31, the stop position of the reel 31 is determined so that only one of the symbols stops on the effective line from the position where the stop switch 42 is operated. It has been. Therefore, the winning probability at the time of winning the CB is 1/3.

  Therefore, when winning the CB, if the stop switch 42 is operated at a position where the winning symbol combination stops on the active line, the symbol combination stops at the active line, but the stop switch 42 is operated at other positions. When selected, the winning symbol combination does not stop at the active line. The “X” symbols of the middle reel 31 and the right reel 31 may be arranged at intervals within 5 symbols. In this way, with respect to the middle and right reels 31, the symbol “X” can be stopped at the active line regardless of the position of the stop switch 42 operated.

  Further, the SB table is used at the time of winning the SB, and the combination of symbols corresponding to the SB is stopped on the effective line within the range of the stop control of the reel 31 and the combination of symbols corresponding to the role other than the SB is set to the effective line The combination of symbols when the reel 31 is stopped is determined so that the reel 31 is not stopped.

  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 small role 1 table, the small role 2 table or the small role 3 table is used on the condition that the small role 1, the small role 2 or the small role 3 is won in the game, and the reel 31 is controlled to stop. The combinations of symbols corresponding to the small role 1, small role 2 or small role 3 are stopped on the active line, and the symbols corresponding to the roles other than the small role 1, small role 2 or small role 3 respectively. 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 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 game table is used when CB game is not won, and the combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the role other than the small role is not stopped on the effective line. It is. Therefore, for the small combination 1 to the small combination 3, within the range of the stop control of the reel 31 during the CB game (for the right reel 31, the symbol next to the symbol at the moment when the stop switch 42 is operated (within 75 ms), the left For the reel 31 and the middle reel 31, within 5 symbols (within 190 ms), the symbol combination at the time of stopping the reel 31 is determined so that the symbol combinations corresponding to the small roles 1 to 3 can be stopped on the effective line. ing.

  Here, in this embodiment, the symbols (bells) of the small role 1 of the right reel 31 are arranged at intervals within 3 symbols, and the symbols (bells) of the small role 1 of the left reel and the middle reel 31 are arranged. Are arranged at intervals within 5 symbols. In the CB gaming table, the stop position of the reel 31 is determined so that the symbols constituting the small combination 1 are stopped at any valid line for any reel 31. Thus, when the CB gaming table is used, the right reel 31 is stopped first, and when the left or middle reel 31 is subsequently stopped, the small combination 1 always wins.

  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 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 medals are automatically inserted without paying out medals.

(Specific game control means)
The specific game control means 68 controls transition to a specific game (1BB game, 2BB game, CB game, RB game or SB game), progress of the game during the specific game, end of the specific game, and the like.

  First, the specific game control means 68 sets the specific game on condition that the combination of symbols corresponding to the specific combination (1BB, 2BB, CB, RB or SB) has stopped on the active line, that is, the specific combination has won a prize. Control to transition. For example, when 1BB wins, it shifts to 1BB game, when 2BB wins, it shifts to 2BB game, when CB wins, it shifts to CB game, when RB wins, it shifts to RB game, and when SB wins Controls to shift to SB game.

  Further, when transitioning to 1BB game, 2BB game, CB game, RB game, or SB game, the role lottery table 62 is switched to a specific role lottery table 62 as shown in FIG.

  The specific game control means 68 is a 1BB game control means 68a (corresponding to the third specific game control means in the present invention) for controlling a specific game (1BB game, 2BB game, CB game, RB game or SB game). ) 2BB game control means 68b (corresponding to the second specific game control means in the present invention), CB game control means 68c (corresponding to the first specific game control means in the present invention), RB game control means 68d ( And a SB game control means 68e (corresponding to the fourth specific game control means in the present invention).

  First, when 1BB wins, the 1BB game control means 68a controls to start the 1BB game from the next game. When the 1BB game is started, the 1BB game control means 68a controls the game state to be set to the bonus game (same as the RB game) immediately before the start of the game. In the bonus game, only the small combination 1 to small combination 3 are selected by the combination lottery means 61 as shown in FIG. However, in the bonus game, the small combination 1 is determined by the combination lottery table 62 so as to win with a high probability of 1 / 1.05.

  The 1BB game control means 68a pays out medals according to the combination when the combination of symbols corresponding to any combination is stopped on the active line during the bonus game. Further, the bonus game of the present embodiment is continued until the number of winning a winning combination reaches a specified number (8 times in this embodiment) or until the number of games reaches a specified number (12 times in the present embodiment). Is done.

  The 1BB game control means 68a controls to end the bonus game when the number of winning prizes or the number of games in the bonus game reaches a specified number. However, immediately before the start of the next game, the 1BB game control means 68a controls to set the game state to the bonus game again.

  As described above, in the control of the slot machine 10, the gaming state is not a bonus game from the end of the game that satisfies the bonus game end condition to just before the start of the next game. However, from the player's point of view, the bonus game is set at the start of all games in the 1BB game, so the bonus game feels like a continuous game (the player recognizes that the gaming state is not a bonus game) Can't do it).

  The end condition of the 1BB game is determined until the payout number of medals during the 1BB game reaches the first predetermined number (345 in this embodiment). Therefore, the 1BB game control means 68a counts the number of medals paid out during the 1BB game, and controls to end the 1BB game when the first predetermined number is reached. That is, during the bonus game, even if the number of winning prizes and the number of games have not reached the prescribed number, when the number of medals paid out reaches the first predetermined number, the 1BB game ends at that time. .

In the above 1BB game, the payout rate is set to exceed 1.
Here, the payout rate is a value indicating an expected value of the payout number with respect to the number of inserted medals. In 1BB game, the number of inserted medals is 3, but for example, when the number of payouts for the small combination 1 is 8, the expected value of the number of medals paid out based on the small combination 1 is 8 / 1.05 = 7.62 It becomes. Therefore, the payout rate is 7.62 / 3 = 2.54, which exceeds 1.

  When 2BB wins, the 2BB game control means 68b controls to execute the 2BB game after the next game. In the 2BB game, first, a general game is started. As shown in FIG. 2, the winning lots in this general game are RB, CB, SB, replay, and small roles 1 to 3. That is, 1BB and 2BB are not drawn. When a CB is won and won during the general game, the CB game is executed only for the next game. In the CB game, the reel 31 is controlled to stop so that combinations 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 active line (except when the combination is won). Therefore, during a CB game, a small combination can be awarded according to the skill of the player regardless of the lottery of the combination. When the CB game ends, the game returns to the general game of 2BB game again.

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

  Here, in the 2BB game of this embodiment, CB wins by 1/5. Since the winning probability at the time of winning the CB is 1/3, the total winning probability is 1/15. For this reason, even if it shifts to CB game at a rate of once in 15 games and wins a small role, the payout rate is below 1.

  Furthermore, during the 2BB game, RB and SB are drawn, but when the RB and SB are won during the 2BB game, the 2BB game is ended. And the RB game or SB game mentioned later is performed.

  Furthermore, the CB game control means 68c performs control so that only one game of the next game is executed when the CB wins. In the CB game, the game is performed with the number of inserted medals being one. In this CB game, the reel stop control means 64 controls to stop the reel 31 using the above-mentioned CB game table when the winning combination is not won. When this one game is over, the CB game is over, and the CB game control means 68c controls to return to the game state before the CB game is executed again.

Here, as shown in FIG. 2, the winning probability of 2BB when the number of inserted medals is three is 1/65536, but when it is one, it becomes as high as 1/3. That is, in the CB game, the number of medals inserted is easy to win 2BB (the same applies to the SB game).
If 2BB is won and won in this CB game, the 2BB game control means 68b will execute the 2BB game after the next game. On the other hand, if 1BB is won and won, the 1BB game is executed by the 1BB game control means 68a after the next game.

Further, the RB game control means 68d controls to start the RB game from the next game when the RB wins. In the RB game, one set of bonus games in the above-mentioned 1BB game is played, that is, until the number of winning prizes or the number of games reaches each specified number of times.
Therefore, in the RB game, the RB game control means 68d continues the RB game until the winning number of games or the number of games reaches the specified number, and when the winning number of games or the number of games reaches the specified number of times, RB It is determined that the game end condition is satisfied, and control is performed to end the RB game. In the RB game, since only the small role 1 to the small role 3 are drawn, there is no case where 1BB or the like is won during the RB game. Therefore, after the end of the RB game, it always returns to the normal game.

  The SB game control means 68e controls to execute the SB game in the next game when the SB wins. An SB game is a game in which only one game is executed. And in SB game, as shown in FIG. 2, lottery of a combination including 1BB and 2BB is performed. Further, in the SB game, the game is performed with the number of inserted medals being one.

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

  In addition, a plurality of types of production patterns are provided according to the winning combination. For example, multiple times each when winning a specified role, winning a small role (non-internal or internal), replaying (non-internal or internal), and non-winning (non-internal or internal) There are various types of performance patterns.

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

(Notification determination means, notification execution means)
The notification determining means 70 determines whether or not to notify information for preventing the combination of symbols corresponding to the CB from stopping on the effective line when the winning combination selection means 61 wins the CB.
As described above, when winning a CB, the symbol combination corresponding to the CB is set to any one of the three types, but information to prevent the symbol combination from stopping on the active line (avoid winnings) To determine whether or not to notify information).

  For example, the control is performed so as to determine whether or not to notify when a normal game is executed. Specifically, it may be determined by lottery using software random numbers. And as probability to determine notifying, setting to 1/2, for example is mentioned. That is, when the game is shifted to the normal game, it is determined to be notified with a probability of 1/2 (in other words, it is determined not to be notified with a probability of 1/2).

Then, the notification executing means 71 controls to notify the information when it is determined to be notified by the notification determining means 70 and the winning lottery means 61 wins CB.
As described above, the symbol combinations corresponding to CB are “A”-“X”-“X”, “B”-“X”-“X”, and “C”-“X”-“X”. When the selected symbol combination is “A”-“X”-“X”, when the stop switch 42 related to the left reel 31 is operated, the symbol “A” is avoided. Informing that the stop switch 42 should be operated (so that the symbol “A” does not stop on the active line) or that the stop switch 42 should be operated aiming at “B” or “C”. .

If such notification is performed, the player can operate the stop switch 42 so as not to win the winning CB.
On the other hand, if the above notification is not performed, when a CB is won, the CB wins with a probability of 1/3.

The slot machine 10 of the present embodiment configured as described above has the following characteristics.
First, in a gaming state in which no specific combination is won (during a normal game), 1BB, 2BB, RB, CB, SB, replay, and a small combination 1 to a small combination 3 are awaited.
When a replay or small role is won and won, a replay is performed or a predetermined number of medals are paid out.
In addition, the probability of winning 2BB and RB in the normal game (when three medals are inserted) is low, so it is rarely won, but if you win and win these roles, 2BB game and RB game respectively. Is executed.

On the other hand, in the normal game, 1BB and CB are won with a relatively high probability. In other words, during the normal game, most of them are in a state of waiting for whether to win 1BB or CB.
If 1BB is won and won, a game in which the payout rate exceeds 1 is executed and continues until the medal payout number reaches 345. Therefore, the gaming state is advantageous to the player.
On the other hand, when winning the CB, as described above, the reel 31 is controlled to stop with a probability of 1/3. However, if the notification execution means 71 notifies the information not to win the winning CB, winning can be avoided. On the other hand, if this information is not notified, the player wins with a probability of 1/3 when CB is won.

  When a CB wins, a CB game is executed in the next game. In this CB game, the number of inserted medals is 1, and the winning probability of 2BB is the highest (the winning probability is set to 1/3). . For this reason, in CB game, it becomes the easiest to win 2BB. However, in CB games, 1BB may be won with a probability of 1/30.

  When 2BB is won and won, 2BB games are executed after the next game. The 2BB game is in a disadvantageous game state for the player because a game with a payout rate of less than 1 is executed until the medal payout number reaches 253. In addition, during the 2BB game, 1BB is not drawn, but RB is drawn (although the winning probability is low). If RB is won during the 2BB game, the 2BB game is ended (punctured). This is because winning of RB is set as one of the end conditions of the 2BB game.

  Similarly, during 2BB games, SB is won with a probability of 1/300. If SB is won during the 2BB game, the 2BB game is ended (punctured). This is because winning of SB is set as one of the end conditions of the 2BB game. When the SB wins and the SB game is executed, in the SB game, a lottery is performed in which 1BB wins with a probability of 1/30 and 2BB wins with a probability of 1/3. In addition, when winning and winning the replay in the SB game, the SB game ends in the game, and in the next game, three medals are automatically inserted and the normal game is played.

  FIG. 3 is a diagram showing the flow of the above gaming state. As shown in FIG. 3, if an RB is won during the 2BB game, the 2BB game is ended, and the RB game is executed by winning the RB. Then, after the end of the RB game, the game shifts to a normal game. In addition, if SB is won during 2BB game, 2BB game is ended and SB game is executed by winning SB. If 2BB is won and won in this SB game, the game shifts to 2BB game again. On the other hand, if 1BB is won and won in the SB game, the game shifts to 1BB game. Furthermore, if the number of medals paid out reaches 253 in the 2BB game, the 2BB game ends and the game shifts to the normal game.

  Further, in the normal game, 1BB lottery is performed, and if 1BB is won and won, 1BB game is executed. In addition, during a normal game, a CB lottery is performed, CB is won, and if the CB wins, the CB game is entered. In this CB game, the winning probability of 2BB is high, so the probability of winning and winning 2BB and shifting to 2BB game is high. On the other hand, if the CB game is not won, the game returns to the normal game. Furthermore, even if a CB is won during a normal game, the notification is executed and if the CB winning can be avoided, it is not necessary to shift to the CB game, and the normal game state is maintained and waiting for the 1BB win. Can do.

In this way, if you continue to be notified during the normal game, you can continue to avoid winning the CB even if you win the CB, so you can win the normal game (avoid winning the CB), 1BB win and win, 1BB Game, normal game (avoid winning CB), 1BB can be won and won, and so on.
On the other hand, if it is not notified during the normal game, if CB is won, CB wins with a probability of 1/3, and further BB game wins and wins 2BB with a probability of 1/3. The game may be repeated.
As described above, the 1BB game and the 2BB game can be repeated through the CB game, and the balls can be given a wave.
In addition, if it is determined how long the game period is to be notified, it is possible to control the length of the normal game state waiting for 1BB winning.

  In addition, although the winning probability of the replay during the normal game is set to 1/7, it can be set to about 1 / 1.2, for example. Thereby, during a normal game, it is possible to set a game state in which replays are frequently won and won. Therefore, the period of waiting for the winning combination in the normal game can be set to a period in which the game can be performed without reducing the number of medals owned.

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) The winning probability of each combination shown in the present embodiment is an example, and is not necessarily limited to the winning probability shown in the embodiment (FIG. 2). Also, the number of acquired games, which is a condition for ending the 1BB game and the 2BB game, is not limited to the number shown in the present embodiment.

  (3) Furthermore, in this embodiment, the 1BB game is set to a gaming state advantageous to the player, and the 2BB game is set to a gaming state disadvantageous to the player. However, the present invention is not limited to this, and the 1BB game and the 2BB game can be interchanged. In other words, in the 1BB game, the game state in which the small role is hardly won is set to be a disadvantageous game state for the player. On the other hand, in the 2BB game, the CB is frequently won, and a game state in which a small role can be won is set. In such a case, it is only necessary to provide a CB with a winning rate of 100% instead of winning a CB at 1/3 as in this embodiment. Then, the CB in the normal game is replaced with the SB, and when the SB is won, it is only necessary to determine whether or not to notify the winning SB.

  (4) In this embodiment, a CB lottery is performed during the 2BB game, and when the CB wins and wins, the CB game is executed. However, the present invention is not limited to this, and during the 2BB game, it is possible to set a state in which the CB game is being continued, that is, a game state in which a small role can be won.

  (5) In the present embodiment, three types of symbol combinations corresponding to CBs are provided, and a case where a winning CB wins and a case where no winning is awarded is provided. However, the present invention is not limited to this. When a winning CB is won, the operation order of the stop switch 42 for winning the winning CB is determined by lottery so that the selected CB does not win when operated in a predetermined operating order. Control may be performed so that the selected CB wins when operated in an operation order other than the predetermined operation order. In this case, the notification execution means 71 may notify the operation order of the stop switch 42 for the winning CB not winning.

(6) In the present embodiment, it is decided to notify the information not to win the CB with a probability of 1/2 at the start of the normal game. However, the present invention is not limited to this, and at what timing and with what probability it is decided to broadcast information is arbitrary.
(7) In addition to determining whether or not to notify, how many times notification is to be performed may be determined by lottery, and notification may be performed for the determined number of times.

It is a block diagram which shows the outline of control of the slot machine in this embodiment. It is a figure which shows the kind of winning combination in this embodiment, and a winning probability. It is a figure which shows the flow of the game state of this embodiment.
