Description

  In the present invention, a plurality of winning modes for winning a lottery during a special game are provided, and the number of game media that a player can acquire during the special game is changed according to the difference in the winning mode. The present invention relates to a slot machine that can have an appropriate wave.

In a conventional slot machine, a special role (BB, etc.) that is advantageous to the player is provided as a lottery, and a special game is performed by winning or winning a special role. It is generally done to increase. Here, when a special role is elected, the special role is controlled so that the special role won't win the prize (the stocked special role is stocked), and the special is carried over under certain conditions. A technique for controlling a winning combination (releases a stocked special winning combination) is known (see, for example, Patent Document 1).
JP 2003-10401 A

  In the above technology, even after winning a special role, lottery of the role including the special role is held, and when the special role is won again, both the special role won so far and the special role won again That is, it controls to carry over the winning of multiple special roles. As a result, when the conditions for winning a special role that has been won are fulfilled, and the winnings of multiple special roles are carried forward, the special role is continuously awarded (special role It is possible to win a prize, shift to a special game, and after the special game ends, the special role can be won again in the first normal game).

  However, in the above-mentioned conventional technology, it is easy to create a wave of the payout rate by carrying over the winning of multiple special roles while releasing multiple special roles that carry over the winning at once. Although it is preferable in that it can be performed, there is a problem that the player's gambling will be raised more than necessary. In particular today, the above technique has a tendency to be less preferred.

  Although it is preferable to set certain restrictions on the technology to carry over the winning of multiple special roles in this way, it will bring about favorable results from the viewpoint of avoiding the player's irritability more than necessary. However, slot machines that continue to win special roles almost according to the theoretical value (probably) have a problem that it is difficult to exert a change in the payout rate and it is difficult to exert the instantaneous power of the output.

  Therefore, the problem to be solved by the present invention is that it is possible to change the winning rate of a special role without stocking multiple winnings of the special role, and at the same time, it is possible for the player to acquire the special game even during the special game. It is to be able to change the number of balls.

The present invention solves the above-described problems by the following means.
(Claim 1)
According to the first aspect of the present invention, a plurality of reels displaying a plurality of types of symbols, a plurality of reels corresponding to the plurality of reels, a stop switch for stopping the rotation of the corresponding reel, A slot comprising: a lottery means for performing; and a reel stop control means for controlling stop of the reel corresponding to the operated stop switch based on a lottery result by the part lottery means when the stop switch is operated The machine lottery means performs a lottery of a role including a special role during a normal game, and wins the special role by a lottery by the role lottery means during a normal game, and corresponds to the special role. Special game control means for controlling the transition from the normal game to the special game when the combination of symbols to be stopped on the active line is provided, and the special game control means includes the special game control means. The first game is controlled to be executed first, and in the first game of the special game, the combination lottery means a combination lottery including a complex combination, and the reel stop control unit In the first game of the special game, when the composite combination is won by lottery by the combination lottery means, when the stop switch is operated in a predetermined operation order, the number of game media to be paid out is X (X is When the reel is controlled to be stopped in an operation order other than the predetermined operation order, the reel is controlled so as to stop the combination of the first symbols set to the natural number) on the effective line. The number of game media to be paid out is set to Y (Y is a natural number equal to or greater than X) and the second symbol combination set to the symbol combination to be shifted from the first game to the second game is stopped on the active line. The special game control means shifts from the first game to the second game when the combination of the second symbols stops on the active line during the first game, The second game is controlled to be executed until the end condition of the second game is satisfied. In the second game of the special game, the special game is set so that the expected value of the number of game media to be paid out is less than the number of game media to be input. In the second game, the winning probability of the combination drawn by the combination lottery means and the number of game media to be paid out when the combination of symbols corresponding to the combination stops on the active line are set. A first symbol for controlling to notify the operation order of the stop switch for stopping the combination of the first symbols on the active line when the combination combination is won by lottery by the combination lottery means during a game. Notification When the special combination is won in the lottery by the combination lottering means during the control means and the normal game, the special combination is selected in the game until the combination of symbols corresponding to the special combination stops on the active line. Special role non-winning that determines the number of games to be executed by lottery to execute special role non-winning control that does not stop the combination of special role winning carry-over means to carry over after the next game and the symbol corresponding to the special role on the active line A game number lottery means, and when the reel stop control means wins the special role by lottery by the role lottery means during a normal game, the number of games determined by the special role non-winning game number lottery means Only when the special role non-winning control is executed, and the number of games for which the special role non-winning control is executed reaches the number of games determined by the special role non-winning game number lottery means. Time, characterized by stop controlling the reel so as to be stopped to enable the line to a combination of symbols corresponding to the special role.

  In the invention of claim 1, when a special combination is won, the combination of symbols corresponding to the special combination cannot be immediately stopped on the effective line, and the combination of symbols corresponding to the special combination is not stopped on the effective line. The number of games for executing the special combination non-winning control is determined by lottery, and the special combination non-winning control is executed for the number of games. Then, when the number of games for which the special combination non-winning control is executed reaches the determined number of games, the reels are controlled so that the combination of symbols corresponding to the special combination can be stopped on the effective line.

When the special combination is won and the combination of symbols corresponding to the special combination stops on the active line, the game shifts from the normal game to the special game.
Among the special games, the first game is provided with a combined role. This composite combination is controlled such that when the stop switch is operated in a predetermined operation order at the time of winning, the first symbol combination stops on the active line. This first symbol combination corresponds to a small combination, and the number of game media to be paid out is set to X.

  On the other hand, when the stop switch is operated in an operation order other than the predetermined operation order at the time of winning the composite combination, the second symbol combination is controlled to stop at the active line. This second symbol combination corresponds to a transitional role for shifting from the first game to the second game, and the number of game media to be paid out is set to Y.

  And if the operation order of the stop switch for stopping the combination of the 1st design to an effective line is notified by the 1st design information control means, a player will operate a stop switch by the operation order. Each time a combination combination is won, it is possible to acquire X game media and continue the first game.

  On the other hand, when the operation order of the stop switch for stopping the first symbol combination on the effective line is not notified, the second symbol combination is stopped on the effective line depending on the operation order of the stop switch. In some cases, the game may shift to the second game. In the second game, the expected value of the number of game media to be paid out is set to be lower than the number of game media to be inserted. Thereby, the number of game media that can be acquired during the special game decreases as the number of times of transition to the second game increases.

The “number of inserted game media” means the number of inserted medals when the game medium is a medal as in the embodiment. For example, when the number of inserted medals per game is three. These three are the number of inserted medals per game.
The “number of game media to be paid out” means the number of payout medals when the game medium is a medal as in the above case. For example, a combination of symbols corresponding to a combination in which 8 medals are paid out is an effective line. When the operation stops, the 8 medals are paid out.

  Furthermore, the “expected value of the number of game media to be paid out” is determined by the winning probability of the winning combination and the number of payouts when the winning combination is made based on the lottery result, This is the number of game media that is theoretically (probably) expected to be paid out (or the number of medals when the game media is a medal). For example, if the winning probability of a winning combination is 1/10 and the number of medals to be paid out at the time of winning the winning combination is 5, the expected value of the paying out number relating to that winning combination per game is 5/10 = 0.5 (sheets / game).

(Claim 2)
According to a second aspect of the present invention, in the slot machine according to the first aspect, the combination of the first symbols is effective when the combination combination is won by lottery by the combination lottery means during the first game of the special game. A first symbol notification determining means for determining whether or not to notify the operation order of the stop switch for stopping at the line, wherein the first symbol notification control means is notified by the first symbol notification determination means; On the condition that the first combination of symbols is determined on the active line, the operation order of the stop switches for stopping the combination on the effective line is notified.

  In the invention of claim 2, during the first game of the special game, it is determined whether or not to notify the operation order of the stop switch for stopping the combination of the first symbols on the active line at the time of winning the combined role. The This determination is made by lottery, for example.

(Claim 3)
The invention of claim 3 is the slot machine according to claim 1 or claim 2, wherein the first role lottery table in which the winning probability of the role including the special role is determined, and the winning probability of the role excluding the special role is determined. A second lottery table that is determined, and the game lottery means, in a game that has not won the special role, draws a role using the first role lottery table and wins the special role In addition, in a game in which the winning of the special role is carried over by the special role winning carry-over means, a lottery of the role is performed by using the second role lottery table, and the second role lottery table is the special role non-winning control. And a special lottery winning lottery table for controlling the reel to stop so that a combination of symbols corresponding to the special bonus can be stopped on an effective line. Is When the special role is won by lottery by the role lottery means during the regular game, only the number of games determined by the special role non-winning game number lottery means is used using the special role non-winning role lottery table. The reel stop control means performs control so as to execute the special combination non-winning control when the combination lottery is performed using the special combination non-winning combination lottery table. Features.

In the invention of claim 3, in a game that is not won for a special combination in a normal game (non-internal game), a combination of lots is performed by the first combination lottery table. In a game in which the special combination non-winning control is executed after winning the special combination, a combination of lots is performed using the special combination non-winning combination lottery table in the second combination lottery table.
In the embodiment, the first combination lottery table corresponds to the first combination lottery table 81, and the second combination lottery table corresponds to the second combination lottery table 82. Further, the special combination non-winning winning lottery table corresponds to the BB non-winning winning table 82a, and the special winning combination winning lottery table corresponds to the BB winning winning table 82b.

(Claim 4)
According to a fourth aspect of the present invention, in the slot machine according to any one of the first to third aspects, in the first game of the special game, the combination lottery means draws only the combined combination. It is characterized by.

(Claim 1)
According to the first aspect of the present invention, after the special combination is won, the special combination non-winning control is executed by the number of games determined by the lottery to change the special combination winning rate, that is, from the normal game to the special game. The rate of transition to can be varied moderately.
In the special game, when the combination role is won, the stop switch operation order is notified, thereby reducing the gaming state in which the first game can be continued and the number of game media that can be obtained by performing the second game. A gaming state can be provided. As a result, even in a special game, a plurality of patterns with different numbers of game media that can be acquired can be set to change the number of balls that a player can acquire even during a special game. Furthermore, since the number of game media that can be acquired by shifting from the first game to the second game can be reduced, the winning probability and the winning rate of the special combination can be set higher accordingly.

(Claim 2)

Accordingly, for example, if the non-winning is set to be extremely low, the special combination non-winning control can be executed by giving priority to the reel stop control based on the winning combination.

(Claim 4)
According to the invention of claim 4, the winning probability of the composite combination can be set high. Thereby, in the special game in which the notification is performed, the number of game media that can be acquired by the player can be increased efficiently.

(Claim 5)
According to the invention of claim 5, the expected value of the net increase of the game media in the special game when the notification is not performed can be set even smaller.

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.

(Start switch, stop switch, bet switch)
As shown in FIG. 1, a start switch 41, a stop switch 42, and a bet switch 45 are electrically connected to the input side (left side in FIG. 1) of the game control means 60.
The bet switch 45 is a switch that is operated when a player inserts a stored medal, and is a switch that activates an active line by the operation. Although the medal insertion slot is not shown in FIG. 1, the medal insertion slot is a part for inserting an actual medal to activate the effective line, as with the bet switch 45. The insertion of the medal is included in the operation of the bet switch 45.

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 66 described later) receives this signal, it controls the motor 32 corresponding to the stop switch 42 to stop the reel 31 related to the motor 32. Take control.

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

(Lamp, speaker, image display device)
Furthermore, the output side of the game control means 60 is electrically connected to effect output devices such as the lamp 21, the speaker 22, and the image display device 23.

  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 45 to insert a previously stored medal, or inserts a medal from the medal insertion 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 or set 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.

  The number of medals inserted in one game can be selected by the player from one to three. When the number of medals inserted is 1, the horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbol combination lines are set as invalid lines. When the number of inserted medals is 2, the horizontal, 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.

(Role)
FIG. 2 is a diagram showing the type of winning combination (the winning combination selected by the winning lottery means 61 described later), the winning probability, the number of payouts, and the like in this embodiment. As shown in FIG. 2, for example, BB as a special combination, small combination 1 to small combination 3 as a small combination, and replay are provided as a combination during a normal game (not inside).

  The special role is a role that shifts from a normal game to a special game (a game that can be expected to win medals more than a normal game and is advantageous to the player). In this embodiment, as shown in FIG. 2, BB (Big Bonus) is provided as a special combination. BB is a role to shift to BB game which is one of special games. In addition, although RB (regular bonus) and SB (single bonus) are mentioned as another special combination, in this embodiment, only BB is provided and RB and SB are not provided.

The small combination is a combination in which a predetermined number of medals are paid out. In this embodiment, three types of small combinations 1 to 3 are provided. As described above, when a plurality of types of small combinations are provided, the combination of symbols corresponding to the combination and the number of medals to be paid out are set to be different depending on the types of small combinations.
Furthermore, the replay is a replaying role that enables a replaying with maintaining the number of medals (the number of bets) inserted in the game.

Furthermore, in this embodiment, a normal game (inside or not inside) and a BB game that is a special game are provided as types of games.
Here, the concept of non-inside and inside is provided in the normal game. “Non-inside” means a game that has not won the special role BB. On the other hand, “inside” means that a BB which is a special part in the game or the game before that is won, but the combination of symbols corresponding to the won BB is not stopped on the active line (the prize has been won). No) refers to a game.

  And, as shown in FIG. 2, a special combination BB, a small combination 1 to 3, and a replay are provided as a combination during a normal game (non-inside). Furthermore, the combination during the normal game (inside the inside) is a combination obtained by removing the special combination BB from the above-mentioned non-inside combination. It should be noted that the normal game in the inside is the same as the normal game in the non-inside, except that BB is not drawn and the winning probability of replay is different.

  Therefore, a lottery of BB is performed during the non-inside of the normal game, but if the BB is won, the normal game in the inside is changed from the normal game in the non-inside, and BB is excluded during the normal game in the inside. A lottery of roles will be held. Further, in the inside game, when the winning BB wins, the game shifts to the BB game.

Further, each BB game has a unique role. The BB game is provided with a first game (described later) and a second game (described later), and as shown in FIG. 2, a combined role is provided as a role during the first game of the BB game. . Although details will be described later, this composite combination is a combination corresponding to both a general small combination and a transition combination. Here, the transition combination is a combination for shifting from the first game of the BB game to the second game. That is, when the transition combination wins during the first game of the BB game, the game shifts from the first game to the second game.
Further, a predetermined combination is provided as a combination during the second game of the BB game. Like the small combination, the predetermined combination is a combination in which a predetermined number (in the present embodiment, one) of medals is paid out.

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. . FIG. 2 also shows the presence / absence of carry-over for the next game.
BB is mentioned as a role carried over. When BB is won, when the reel 31 is stopped, the combination of symbols corresponding to BB is stopped on the active line, and in the game until the BB wins, the BB win is controlled to be carried over from the next game onwards. The

  On the other hand, a combination other than BB (small combination 1 to small combination 3, replay, composite combination and predetermined combination) is not carried over. In the lottery of a winning combination, when these winning combinations are won, the winning combination is effective only in the game, and the winning combination is not carried over after the next game. That is, 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, but at the end of the game, regardless of whether or not the winning winning combination has been won. The right to cease to exist.

  A combination of symbols of the reel 31 corresponding to the above various combinations is determined in advance. When all the reels 31 are stopped, a combination of symbols corresponding to any one of the predetermined combinations stops on the active line, and when a winning combination of the combination is won, a predetermined number of medals are paid out. It is.

  Further, as shown in FIG. 2, the combined combination is a combination in which the operation order of the stop switch 42 is determined. Specifically, the combination combination is a combination of symbols (in this embodiment, 14 medals are paid out only when the stop switch 42 is operated in a predetermined operation order (pushing order) at the time of winning. “Bell”-“Bell”-“Bell” is a combination in which the first symbol combination in the present invention is controlled to be able to stop (to be able to win a prize) on the active line.

On the other hand, if the stop switch 42 is operated in an operation order other than the predetermined operation order at the time of winning the combined combination, 15 medals are paid out and the transition from the first game to the second game is made. A combination of symbols corresponding to a combination (in this embodiment, “bell”-“bell”-“RP”. The second combination of symbols in the present invention) is controlled to be able to stop (to be able to win a prize) on the active line. It is a role.
Note that “stop (win) is possible” means that the reel 31 stops (wins) within the range of the stoptable position of the reel 31 (within the range of stop control).

  The game control means 60 includes the following part lottery means 61 and the like. The following means in the present embodiment are examples, and the game control means 60 is not limited to the means shown in the present embodiment.

(Role lottery means)
The role lottery means 61 performs lottery of a role (BB, which is a special role, a small role 1 to a small role 3, a replay, a combined role or a 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, if the extracted random number value belongs to the BB winning area, it is determined as BB winning, and if it belongs to the non-winning area, it is determined as non-winning.

  As shown in FIG. 2, the role lottery means 61, for example, in a non-internal normal game, is based on a random number value extracted from BB, small role 1 to small role 3, replay and non-winning. Alternatively, the non-winning is determined. In addition, when the inside of a normal game is entered, a lottery of a winning combination is performed except for BB.

(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 (normal game (non-inside / inside) and BB game (first game and second game)).
Each combination lottery table 62 has a predetermined range of lottery areas. The lottery area is divided into a winning area and a non-winning area for each combination, and as shown in FIG. Is set to a predetermined ratio so as to have a preset winning probability.

  Although not shown, the winning area and the non-winning area of each combination are determined for each number of inserted medals (1 to 3) and for each set value of the payout rate. The winning probability is one example when setting values for the number of inserted medals and the payout rate are determined.

  First, a first combination lottery table 81 and a second combination lottery table 82 are provided as the combination lottery table 62 used during normal games. The first combination lottery table 81 is used when the normal game is not inside, and BB, small combination 1 to small combination 3, and winning probability of replay are defined respectively.

Further, the second combination lottery table 82 is used when the inside of the normal game, and the winning combinations of the small combination 1 to the small combination 3 and the replay are respectively determined.
Furthermore, the second combination lottery table 82 includes a BB non-winning table 82a and a BB winning table 82b.

The BB non-winning table 82a does not win the winning BB by using the winning combination of the winning combination and the stop control of the reel 31 (strictly speaking, it is very difficult to win, in other words, virtually no winning is achieved. Meaning) It is a role lottery table 62 used when executing BB non-winning control (described later).
On the other hand, the BB winning table 82b is a role lottery table 62 used when the reel 31 is stopped and controlled so that a winning BB can be won.

  Further, the BB non-winning table 82a and the BB winning table 82b have different replay winning probabilities. In this embodiment, the BB winning table 82b is the same as the replay winning probability (1 / 7.3) in the first combination lottery table 81, but the replay winning probability in the BB non-winning table 82a is , 1 / 1.15 is set high.

Further, a BB gaming combination lottery table 83 is provided as the combination lottery table 62 used during the BB game. The BB game combination lottery table 83 includes a first game table 83a and a second game table 83b used in the first game of the BB game.
In the first game table 83a, the winning probability of the combined combination is determined. In the second game table 83b, the winning probability of the predetermined combination is determined.

(Means to carry over special roles)
In the game until the combination of symbols corresponding to BB stops on the active line (until BB wins) when the special role winning carry-over means 63 wins the special role BB, the winning game of the BB is the next game It controls to carry over after that.
In the present embodiment, when winning a BB, a special combination flag 63a is provided to store the winning of the BB. When BB is won, the special combination flag 63a is turned on (from off). The on state of the special combination flag 63a is maintained until BB wins, and when the BB wins, the special combination flag 63a is returned from on to off.

(Special role non-winning game frequency lottery means)
The special combination non-winning game number lottery means 64 determines the number of games for executing BB non-winning control that does not stop the combination of symbols corresponding to the special combination BB on the active line. In addition, although the lottery can be performed regardless of the winning of the BB, in the present embodiment, the lottery is performed by a game at the time of winning the BB.
In addition, the number of games for BB non-winning control is at least one in this embodiment. Therefore, in the game at the time of winning the BB, the BB non-winning control is executed, so that the BB does not win in the game.

  Furthermore, the maximum number of games for BB non-winning control is 1280 games in the present embodiment. The average value of the number of games is set to about 200 to 300, for example. Therefore, since the winning probability of BB is 1/120, the winning rate of BB is about 1/320 to 1/420.

  In this embodiment, the lottery of the number of games is performed using software random numbers. For example, a 16-bit random number is used, and the number of games corresponding to the extracted random number value is set to a predetermined ratio between 1 and 1280, respectively.

(BB non-winning flag)
The special combination non-winning game frequency lottery means 64 includes a BB non-winning flag 64a in order to store the lottery result. The BB non-winning flag 64a is won for the BB by the role lottery by the role lottery means 61, and when the number of games is determined by the special role non-winning game number lottery means 64, the game continues for the determined number of games. It is a flag that is turned on and controlled from on to off when the number of games played is exhausted. That is, the BB non-winning flag 64a is a flag referred to when determining whether or not the BB non-winning control is executed in the game.

  The game control means 60 controls on / off of the BB non-winning flag 64a. For this reason, the game control means 60 controls to turn on the BB non-winning flag 64a when BB is won by the winning lottery by the winning lottery means 61. Then, the number of games continues to be counted while being turned on, and when the number of games determined by lottery by the special role non-winning game number lottery means 64 is reached, the BB non-winning flag 64a is turned off. Control.

(Operation order selection means)
The operation order selection means 65 is the first symbol among the combinations of symbols corresponding to the winning combination when the winning combination is won in the lottery by the winning lottery means 61 during the first game of the BB game. The operation order of the stop switch 42 is selected (determined) for stop control of the reel 31 that stops the combination of “bell”-“bell”-“bell” on the effective line.

Here, when the stop switches 42 respectively corresponding to the left, middle, and right reels 31 are represented by left, middle, and right, the operation order of the stop switches 42 is “left middle right”, “left and right middle”, There are six types: “middle left and right”, “middle right and left”, “middle right and left”, and “middle right and left”.
In the present embodiment, when a combination combination is won, one of the operation orders is determined by a lottery using software random numbers, and the determined combination of the first symbols is an effective line. Set the operation order to stop (win). That is, the other five operation orders are set to an operation order in which “bell”-“bell”-“RP”, which is the second symbol combination, is stopped (winned) on the active line.

  For example, when the operation order for winning the combined role and stopping the first symbol combination on the active line is determined to be “left / right / middle”, the stop switch 42 is operated in the order of “right / left / middle”. The first symbol combination is controlled to stop at the active line. On the other hand, when the stop switch 42 is operated in the other five operation orders, the second symbol combination is controlled to stop at the active line. As described above, when the combination combination is won, the operation order of the stop switch 42 and the combination of symbols corresponding to the operation order are determined.

  FIG. 3 is a plan view showing an arrangement of 21 symbols on the outer peripheral surface of each reel 31 in the present embodiment. In FIG. 3, only the symbol arrangement of “Bell” and “RP” is shown, and a predetermined symbol is also displayed in a blank part in the drawing, but the illustration is omitted here.

  In FIG. 3, all the symbols of “bell” are arranged on each reel 31 at intervals within 5 symbols. Furthermore, the symbols “RP” are arranged on the right reel 31 at intervals of 5 symbols or less. Therefore, the symbols “Bell” and “RP” which are symbols constituting the composite role at intervals within the range of the stoptable position of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). Are arranged on the reel 31. As a result, at the time of winning of the combined role, it is possible to always control the combination of symbols of the selected combined role to be stopped on the active line according to the operation order of the stop switch 42.

  On the other hand, for example, when the symbols “bell” and “RP” are arranged at intervals exceeding the range of the stoptable position of the reel 31 (for example, 6 symbols), “bell” and “RP” are effective. Unless the stop switch 42 is operated at a position where the line can be stopped, the symbols constituting the selected composite combination cannot be stopped on the active line. This means that “the combination of symbols stops at the effective line within the range of the stoppable position of the reel 31”.

(Reel stop control means)
The reel stop control means 66 includes a lottery result of the combination by the combination lottery means 61 when the stop switch 42 is operated, a timing when the stop switch 42 is operated, and a stop switch when a combination combination is won. Based on the operation order of 42, the stop control table 66b is referred to determine the stop position of the reel 31 corresponding to the stop switch 42, and the motor 32 is driven to control the reel 31 to the determined position. Is controlled to stop.

  For example, the reel stop control means 66 stops the reel 31 so that the combination of symbols corresponding to the small combination 1 is stopped on the effective line within the range of the stoptable position of the reel 31 in the game where the small combination 1 is won. The reel 31 is controlled to stop so that the combination of symbols corresponding to the combination other than the small combination 1 is not stopped on the effective line.

(Stop control selection means)
The stop control selection means 66a is in the inside of the BB in the normal game and corresponds to the winning replay when the replay is won when the BB non-winning table 82a is used to draw the winning combination. It is selected whether or not the combination of symbols is stopped on the active line (the winning replay is awarded). In the present embodiment, it is determined using a software random number.

  When the BB non-winning table 82a is used, as shown in FIG. 2, the replay winning probability changes from 1 / 7.3 to 1 / 1.15. In this embodiment, when winning a replay, not all winning replays are won, but control is performed to select whether or not to win according to stop control.

In this embodiment, at the time of winning the replay, the software random number is selected to win the winning replay with a probability of 15.7%, and the winning replay is selected with a probability of 84.3%. Control to do.
As a result, the replay wins at 15.7% of 1 / 1.15 which is the replay winning probability, so that the replay winning rate during the game is about 1 / 7.3. Therefore, it becomes equal to the winning probability of non-inside replay.

(Stop control table)
The stop control table 66b defines the symbol stop position of the reel 31 from the lottery result of the combination by the combination lottery means 61 and the position of the reel 31 at the moment when the stop switch 42 is operated.
The stop control table 66b includes the following BB table, small combination 1 to small combination 3 table, replay table, non-winning table, first symbol stop control table, second symbol stop control table, and predetermined combination table.

  The BB table is used when the BB is won (when the special combination flag 63a is turned on), and is used on condition that any combination is not won in the game, and the reel 31 is stopped. Within the range of possible positions, the combination of symbols corresponding to BB is stopped on the effective line and the combination of symbols corresponding to the role other than BB is not stopped on the effective line. It is determined.

  Here, in the present embodiment, “within the range of the stoptable position of the reel 31” in the stop control table 66b means (1) the reel from when the stop switch 42 is operated (instant) until the reel 31 is stopped. This means that the movement control amount of 31 is within 5 symbols, or (2) the stop control time from when the stop switch 42 is operated (instant) until the reel 31 is stopped is within 190 ms.

  Further, the small roles 1 to 3 tables are used on condition that the small roles 1 to 3 are won in the game, and within the range of positions where the reel 31 can be stopped, respectively. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the combination 3 is stopped on the effective line, and other combinations of symbols are not stopped on the effective line.

  Furthermore, if the replay table has been won for replay in the game, or if the BB non-winning table 82a is used and a lottery of a role is being performed, stop control selection means 66a at the time of winning the replay The combination of symbols corresponding to the role other than the replay is used while the symbol combination corresponding to the replay is stopped on the effective line within the range of the stoppable position of the reel 31. The combination of symbols at the time when the reel 31 is stopped is determined so as not to stop at the effective line.

  Furthermore, the non-winning table is the time when the winning combination is not won, or when the winning combination of the BB is not used when the BB non-winning table 82a is used, the stop control selecting means 66a is selected at the time of winning the replay. The symbol combination is determined when the reel 31 is stopped so that the symbol combination corresponding to any combination is not stopped on the active line.

  In addition, the first symbol stop control table is used on condition that the stop switch 42 is operated in an operation order for stopping the combination of the first symbols on the effective line when the composite combination is won, and the reel 31 can be stopped. Within the position range, the symbol combination corresponding to the first symbol combination is stopped on the effective line, and the combination of symbols other than the first symbol combination is not stopped on the effective line. The combination of symbols at the time of stopping is determined.

  Similarly, the second symbol stop control table is used on condition that the stop switch 42 is operated in the operation order for stopping the combination of the second symbols on the effective line when the composite combination is won, and the reel 31 is stopped. The reel 31 is set so that the symbol combination corresponding to the second symbol combination is stopped on the effective line within the range of possible positions, and the symbol combinations other than the second symbol combination are not stopped on the effective line. The combination of symbols at the time of stopping is determined.

  Furthermore, the predetermined combination table is used on the condition that the predetermined combination is won in the game, and the combination of symbols corresponding to the predetermined combination is stopped on the effective line within the range of the stoppable position of the reel 31 and the predetermined combination is stopped. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the combination other than the combination is not stopped on the effective line.

  As described above, when the reel stop control means 66 uses any one of the stop control tables 66b to stop the combination of symbols corresponding to any combination on the effective line, the range of the stoppable position range 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.

  By the way, of the first symbol combination and the second symbol combination, the symbols of the left reel 31 and the middle reel 31 are both “bells”. Therefore, in both the first symbol stop control table and the second symbol stop control table, when the left stop switch 42 or the middle stop switch 42 is first operated, either the corresponding left reel 31 or middle reel 31 is selected. The stop position of the left reel 31 or the middle reel 31 is determined so that the “bell” symbol stops on the active line.

  On the other hand, when the operation order (right middle left or right middle left) starting from the right stop switch 42 is selected as the operation order of the stop switch 42 for stopping the first symbol combination on the effective line, When the right stop switch 42 is operated, since the operation order of the stop switch 42 is not finally determined at that time, both the first symbol stop control table and the second symbol stop control table are “ The stop position of the right reel 31 is determined so that both the “bell” and “RP” symbols stop at one of the effective lines.

  For example, in FIG. 3, when the right reel 31 is stopped so that the symbols of symbol numbers 1 to 3 appear in the display window frame, the symbol of “bell” only stops on the active line, and the symbol of “RP” Does not stop at the active line. Further, when the right reel 31 is stopped so that the symbols of symbol numbers 4 to 6 appear in the display window frame, the symbol of “RP” only stops at the effective line, and the symbol of “bell” is the effective line. Never stop. For this reason, the stop position of the right reel 31 is determined so that the right reel 31 does not stop at the above position.

  Therefore, in the above example, the stop position of the right reel 31 is determined so that, for example, symbols 2 to 4 or symbols 3 to 5 appear in the display window frame. Thus, when the right reel 31 is first controlled to stop, both the “bell” and “RP” symbols always stop at one of the effective lines.

  Since the operation order of the stop switch 42 is determined when the second stop switch 42 is operated, the operation order of the operated stop switch 42 is the operation order corresponding to the first symbol combination. Uses the first symbol stop control table to stop the combination of symbols “bell”-“bell”-“bell” on any active line (“bell”-“bell” on any active line). The reel 31 is controlled to stop so that the symbol combination “RP” does not stop.

  On the other hand, when the operation order of the operated stop switch 42 is the operation order corresponding to the combination of the second symbols, the “bell” is set to any valid line using the second symbol stop control table. -The reel 31 is controlled to stop so that the symbol combination "Bell"-"RP" stops (the combination of symbols "Bell"-"Bell"-"Bell" does not stop for any active line). The

  In addition, when a small combination 1 or replay is won inside the BB, the small combination 1 or replay won in the game is given priority as the winning combination. For example, when the small game 1 is won in the game inside, the BB is won before the game in the game, but the small game 1 is given priority as the winning game, and the reel stop control means 66 The reel 31 is controlled to stop so that the small combination 1 can win a prize. That is, when the small combination 1 is won in the inside of the BB, the small combination 1 table is used without using the BB table or the non-winning table. Furthermore, when the replay is won in the inside of the BB, the BB table is not used, and the replay table or the non-winning table is used.

  Here, when the reel stop control means 66 carries over the winning of BB (when the special combination flag 63a is on), (1) when the BB non-winning flag 64a is on, the reel stop control means 66 BB non-winning control is executed to stop the reel 31 so as not to stop the corresponding symbol combination on the active line. (2) When the BB non-winning flag 64a is turned off, the symbol corresponding to BB is Control is performed to execute BB winning control for stopping the reel 31 so that the combination can be stopped on the effective line.

  Specifically, when the special combination flag 63a is on and the BB non-winning flag 64a is on, the BB non-winning table 82a is used to draw a lottery. When the BB non-winning table 82a is used, the probability of non-winning is 1/2300, so the probability of non-winning is extremely low. Therefore, since it is very rare for a game that has won the BB to be non-winning (not to win a small role or replay in the game), there are very few opportunities to win the BB. The above means “BB non-winning control” in the present embodiment.

  On the other hand, the BB non-winning control is performed only for the number of games determined by the special role non-winning game number lottery means 64, and when the number of games is reached, the BB winning control is performed after the next game. During the BB winning control, the BB winning table 82b is used to draw a winning combination. When the BB winning table 82b is used, as shown in FIG. 2, the player wins with a probability of 1 / 1.36, and the BB table is used in this non-winning game. As a result, in the game, the reel 31 is controlled to stop so that the combination of symbols corresponding to BB can be stopped on the active line. The above means “BB winning control” in the present embodiment.

  In the present embodiment, the reel stop control means 66 controls the reel 31 to stop using the non-winning table as an exception in a game where BB is won. In the game where BB is won, the BB non-winning table 82 a is not selected as the role lottery table 62. In the BB winning game, the BB table is usually used, and the combination of symbols corresponding to BB is controlled to stop at the effective line within the range of the stoppable position of the reel 31. It is possible that BB wins in the winning game. In order to prevent this, in this embodiment, such an exception is provided and the reel 31 is controlled to stop.

(Operation order detection means)
The operation order detection unit 66c detects the operation order of the stop switch 42 when a combination combination is won in the combination lottery by the combination lottery unit 61. As described above, the stop switch 42 is provided for each reel 31 (for each of the left, middle, and right reels 31). However, the stop switch 42 that is turned on first (first) is the left, Which reel 31 corresponds to the reel 31 among the middle and right reels 31, and which stop switch 42 turned on secondly corresponds to which reel 31 among the left, middle and right reels 31. It is detected whether it is the stop switch 42. When each stop switch 42 is turned on, an identification signal is transmitted to the operation order detection means 66c, and the operation order of the stop switch 42 is detected based on the identification signal.

(Stop symbol discrimination means)
The stop symbol discriminating means 67 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 67 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 67 does not discriminate the symbol combination after the reel 31 is actually stopped, but from the position of the reel 31 at the moment when the stop switch 42 is operated, the reel 31 is stopped by the stop control table 66b. It is also possible to determine the combination of symbols on the effective line when the stop position is determined.

(Winning process means)
The winning processing means 68 is determined by the stop symbol determining means 67 that the combination of symbols stopped on the active line when the reel 31 is stopped matches the symbol combination corresponding to one of the combinations, and the winning combination is won. Sometimes, a predetermined number of medals corresponding to the winning combination is paid out to the player, or processing such as credit addition is performed. Further, at the time of replay winning, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

(Special game control means)
The special game control means 69 controls the transition from the normal game (internal game) to the special game BB game, the progress of the game during the BB game, the end of the BB game, and the like.

First, the special game control means 69 shifts from the normal game to the BB on condition that the combination of symbols stopped on the active line matches the symbol combination corresponding to the special role BB and the BB wins. To control.
When the game is shifted to the BB game, the role lottery table 62 is a BB game-specific role lottery table 83 (first game table 83a during the first game, and second game table 83b during the second game). Is used.

The special game control unit 69 first starts the first game in the BB game. In the first game, the winning combination drawn by the winning combination lottery means 61 is a combined combination (only) as shown in FIG. As shown in FIG. 2, the winning combination probability of the combined role is set to 65535/65536, that is, approximately 1 (100%).
Then, the special game control means 69 changes the first game from the first game on condition that the combination of symbols stopped on the active line coincides with the second symbol combination corresponding to the transitional combination. Shift to 2 games.

  In the second game, as shown in FIG. 2, only the predetermined combination is selected by the combination lottery means 61. In the second game, as shown in FIG. 2, the winning probability of the predetermined combination is set to 1/65536, that is, approximately 0 (0%). Thus, in the present embodiment, in the second game of the BB game, in the second game, the winning lottery means 61 draws the winning combination (expected value) so that the winning lottery means 61 draws the winning combination (expected value) (the expected value). The winning probability of a predetermined combination) and the number of medals to be paid out when the combination of symbols corresponding to the combination stops on the active line are set.

Then, in the second game of the present embodiment, until the predetermined number of winnings 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 the present embodiment, 12 times). Will continue.
The special game control means 69 controls to end the second game and return to the first game again when the number of winnings or the number of games of the predetermined role in the second game reaches the specified number.

  Further, the special game control means 69 continues to determine whether or not the BB game end condition is satisfied. When it is determined that the BB game end condition is satisfied, the special game control means 69 ends the BB game with the game and shifts to the normal game. Control to do.

In the present embodiment, the BB game end condition is set such that the number of medals paid out during the BB game exceeds the upper limit M. Furthermore, the upper limit M is set to 360 sheets in the present embodiment.
In the present embodiment, during the BB game, the number of medals inserted in the first game and the number of medals inserted in the second game are uniformly set to three. That is, it is controlled so that the game cannot be started with one or two cards.

Furthermore, in this embodiment, the special game control means 69 includes a payout number counting means 69a for counting the number of medals paid out during the BB game. The number-of-payout counting means 69a keeps updating the number of paid out games and games.
When the special game control means 69 determines that the value counted by the payout number counting means 69a exceeds the upper limit M, it determines that the BB game end condition is satisfied. It should be noted that even if the winning combination is won in the game and the medal is paid out, even when the upper limit M is exceeded, the medal related to the winning in the game is controlled to be paid out (all).

(First symbol notification control means)
The first symbol notification control means 71 stops the combination of the first symbols (“BELL”-“BELL”-“BELL”) on the active line when a combination combination is won during the first game of the BB game. Thus, control is performed so as to notify the operation order of the stop switch 42 for the purpose.
In the present embodiment, the first symbol notification control means 71 includes first symbol notification determination means 71a. The first symbol notification determination means 71a is a stop switch 42 for stopping the combination of the first symbols on the active line when a combination combination is won by lottery by the combination lottery means 61 during the first game of the BB game. It is determined whether or not to notify the operation order, and in the present embodiment, it is determined by lottery using software random numbers.

This lottery is performed when the BB game is started in this embodiment. However, the lottery time is arbitrary, and may be, for example, when BB is won.
In addition, the winning probability of whether or not to perform notification may be set to win with a probability of 1/2, for example. And when winning by this lottery, the 1st symbol alert | report control means 71 is controlled during the 1st game of BB game to perform the said alert | report at the time of winning of a composite combination. Further, when the lottery is not won, control is performed so as not to notify.

  Furthermore, the first symbol notification control means 71 includes a first symbol notification flag 71b in order to determine whether or not to execute the notification. The first symbol notification flag 71b is a flag that is turned on when it is determined to perform the notification, and is otherwise turned off.

  The first symbol notification control means 71 determines the on / off state of the first symbol notification flag 71b when the combination combination is won, and when it is ON, the first symbol notification control means 71 stops the combination of the first symbols on the active line. It is determined that the operation order of the stop switch 42 is notified.

  In addition, various methods may be used as the notification method. For example, a notification method using the image display device 23 or a notification using the lamp 21 (particularly, a back lamp arranged on the inner peripheral surface side of the reel 31). (E.g., a method in which only the reel 31 corresponding to the stop switch 42 to be operated is turned on by a back lamp and the others are turned off).

  As a specific notification method, for example, when the stop switch 42 is operated in the order of right, left, and middle, and the first symbol combination is stopped on the active line, the image display device 23 is set to “right → left → “Medium” is displayed. The other stop switches 42 are displayed in the same manner in the operation order.

  At the time of winning the combined role, of the six operation orders, one operation order is the operation order in which the combination of the first symbols stops on the active line, and the other five operation orders are the second operation order. This is the operation order in which the combination of symbols stops on the active line. For this reason, if the notification is not performed, the combination of the second symbols stops at the active line with a probability of 5/6 when the composite combination is won, and the game shifts from the first game to the second game. On the other hand, in the case of notification, the operation order for stopping the first symbol combination on the effective line is notified, so if the operation order is followed, the first symbol combination is always set to the effective line. You can stop and stay in the first game.

Next, it will be examined how much difference the expected value of the number of medals to be paid out depends on whether or not the first symbol notification control means 71 is notified.
The “expected value of the number of payouts” means the number of probabilities that medals per predetermined number of games are paid out, and is determined by the winning probability of the winning combination and the number of payouts. For example, if only one combination with a winning probability set to 1/10 is provided, and the number of medals to be paid out when winning that combination is 5, then 5 medals will be paid out per 10 games. Will be. Therefore, the expected value of the number of medals paid out per game is 5/10 = 0.5 (sheets / game).

Here, for convenience of calculation, the winning probability of the combined role is set to 1 during the first game of the BB game, and the winning probability of the predetermined role is set to 0 during the second game.
In the case where the notification is performed by the first symbol notification control means 71, when the notification is to be followed, three medals are inserted, whereas the combination of the first symbols stops on the active line. Since 14 medals are paid out, the net increase in the number of medals per game (the number of payouts-the number of input) is
14-3 = +11.

Therefore, when the notification is made, the BB game is ended only by the first game without shifting to the second game, so the first game is continued until the medal payout number exceeds 360. . Therefore, when 14 medals are paid out in one game, it is the 26th game that exceeds 360 (the 26th game results in a payout number of 364). In this case, the net increase in BB games is
+111 x 26 games = +286.

On the other hand, it is assumed that when the notification is not performed by the first symbol notification control means 71, the stop switch 42 is operated so that the combination of the second symbols stops at the effective line with probability 1.
At this time, since the combination of the second symbol stops on the active line in the first game of the first game, the net increase in the game is
15-3 sheets = + 12 sheets.

In addition, when 12 games are played after the transition to the second game, the net increase in the second game of one time (12 games)
-3 x 12 games = -36.
Therefore, in order for the number of payouts to exceed 360 in the BB game, 25 first games will be performed, and 24 second games (12 per game) before the 25th first game is performed. Game)), the net increase in BB games is
(+12 pieces × 25 games) + (− 36 pieces × 24 times) = − 564 pieces.

  As described above, when the notification is given, +286 medals can be increased during the BB game, but when the notification is not given, 564 medals are reduced even in the BB game. Therefore, if the notification is made, it is advantageous for the player, and if the notification is not made, it is disadvantageous for the player.

  As described above, in the present invention, during the BB game to be notified, the expected value of the number of paid-out medals is positioned higher than the number of inserted medals (the payout rate exceeds 100%), and no notification is given. During the BB game, the expected value of the number of paid-out medals is lower than the number of inserted medals (the payout rate is less than 100%).

  And if the balance of whether to alert | report during BB game is taken, a payout rate can be set to a desired value. Moreover, even if it is a BB game, the winning probability of BB can be set high by setting so that a payout rate may be less than 100%.

Next, the flow of processing during a game in the present embodiment will be described based on a flowchart.
4 and 5 are flowcharts showing the flow of the game during the normal game. FIG. 5 is a flowchart following FIG.
In step S1 of FIG. 4, the game control means 60 continues to detect whether the start switch 41 is turned on. When ON is detected, an effective line corresponding to the number of inserted medals is determined, each reel 31 is started, and the process proceeds to the next step S2.

  In step S2, it is determined whether or not the special combination flag 63a is on (whether or not the BB has been won before the game, in other words, whether or not the BB win has been carried over). When the special combination flag 63a is on, the process proceeds to step S3, and when it is not on, the process proceeds to step S6. In step S3, it is determined whether or not the BB non-winning flag 64a is on, that is, whether or not the BB non-winning control is executed. When it is determined that the BB non-winning flag 64a is not on, the process proceeds to step S4. When it is determined that the BB non-winning flag 64a is on, the process proceeds to step S5.

When the process proceeds to step S4, since it is a game in which the BB winning is carried over and the BB non-winning control is not executed, the BB winning table 82b in the second winning lottery table 82 is used as the winning lottery table 62. Set, and proceed to step S7.
In addition, when the process proceeds to step S5, since it is a game in which the BB winning is carried over and the BB non-winning control is executed, the second lottery table 82 for the BB non-winning is selected as the second lottery table 62. The table 82a is set, and the process proceeds to step S7.
Furthermore, when the process proceeds to step S6, it is a case where the winning of BB is not carried over, so the first combination lottery table 81 is set as the combination lottery table 62, and the process proceeds to step S7.

In step S7, the combination lottery means 61 performs combination lottery using the combination lottery table 62 set in steps S4 to S6. Note that when the BB is won in this lottery, the special combination flag 63a is processed (processing to turn on from off).
In the next step S8, it is determined whether or not BB is won (by the game) in the lottery of step S7. When it is determined that the player has won, the process proceeds to step S9. When it is determined that the player has not been won, the process proceeds to step S11.
In step S9, the special role non-winning game number lottery means 64 determines the number of games for executing the BB non-winning control by lottery, and proceeds to step S10. In step S10, the BB non-winning flag 64a is turned on, and the process proceeds to step S11.

  In step S11, 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 S12, and the reel stop control means 66 has the BB non-winning flag 64a turned on (that is, the BB non-winning table 82a is used in the game). In addition, it is determined whether or not the game has been won for replay. When it is determined that the BB non-winning flag 64a is on and the replay is won, the process proceeds to step S13. When it is determined that the replay is not selected, the process proceeds to step S14.

In step S13, the stop control selection means 66a selects whether or not to replay, and when selecting to replay, sets the replay table as the stop control table 66b and does not win the replay. Is selected, the non-winning table is set as the stop control table 66b, and the process proceeds to step S15.
On the other hand, in step S14, the reel stop control means 66 sets a stop control table 66b corresponding to the winning combination, and proceeds to step S15.

Then, the process proceeds from step S13 or step S14 to step S15, and the reel stop control means 66 controls the drive of the motor 32 to control the stop of the reel 31 corresponding to the stop switch 42 that is turned on.
Next, proceeding to step S16, the game control means 60 determines whether or not all the reels 31 have stopped, and when determining that they have stopped, it proceeds to step S17 (FIG. 5). On the other hand, when it is determined that all the reels 31 are not yet stopped, the process returns to step S11.

  In step S17, the stop symbol determination means 67 determines whether or not any winning combination has been won (whether or not the combination of symbols corresponding to any winning combination has stopped on the active line), and determines that a winning has been won. If so, the process proceeds to step S18. On the other hand, when it is determined that no winning is made, the process proceeds to step S19. In step S18, the winning processing means 68 performs processing such as payout, that is, processing such as payout according to the winning combination. For example, when the small combination 1 wins, the number of medals corresponding to the small combination 1 (8 in this embodiment) is paid out, and when the replay is won, the number of medals inserted in the game is automatically inserted. Process. Then, the process proceeds to step S19.

In step S19, it is determined whether or not the BB non-winning flag 64a is on. When it is determined that the BB non-winning flag 64a is on, the process proceeds to step S20, and when it is determined that it is not on, the process proceeds to step S22. In step S20, it is determined whether or not the BB non-winning game frequency lottery means 64 has reached the BB non-winning game frequency. When it is determined that it has arrived, the process proceeds to step S21, and when it is determined that it has not been reached, the process proceeds to step S22.
In step S21, the game control means 60 turns off the BB non-winning flag 64a from on to proceed to step S22.

  In step S22, it is determined whether or not BB, which is a special role, has won (whether or not the symbol combination corresponding to BB has stopped on the active line). If it is determined that the winning has been won, the process proceeds to step S23. The special game control means 69 controls to shift to the BB game which is a special game. When it is determined that BB has won, the special combination flag 63a is processed (processing to turn it off). On the other hand, when it is determined in step S22 that BB has not won, the processing according to this flowchart is terminated.

6 to 8 are flowcharts showing the flow of processing of the BB game. FIG. 7 is a flowchart following FIG. 6, and FIG. 8 is a flowchart following FIG. 7. When the process proceeds to step S23 in FIG. 5, the process proceeds to step S31 and subsequent steps in FIG.
First, in step S31 of FIG. 6, the special game control means 69 performs a BB game start process. Specifically, the count value of the payout number counting means 69a is set to 0 in order to clear the payout number of medals during the BB game. And the special game control means 69 is controlled to start the 1st game of BB game.

  In the next step S32, whether or not the first symbol notification determining means 71a notifies the operation order of the stop switch 42 for stopping the combination of the first symbols on the active line when the combination combination is won during the first game. Do the lottery. When the lottery is won, the first symbol notification flag 71b is processed (a process for turning it off to on).

In the next step S33, the game control means 60 continues to detect whether or not the start switch 41 is turned on. When the start switch 41 is detected, the game control means 60 starts each reel 31 and proceeds to the next step S34. The lottery means 61 performs lottery drawing. In addition, as shown in FIG. 2, only the combination combination is selected by lottery.
Then, in the next step S35, it is determined whether or not a composite combination has been won. When it is determined that the player has won, the process proceeds to step S36. When it is determined that the player has not been won, the process proceeds to step S44 (FIG. 7).

  In step S36, it is determined whether or not the first symbol notification flag 71b is on. When it is determined that the first symbol notification flag 71b is on, the process proceeds to step S37, and when it is determined that it is not on, the process proceeds to step S38. In step S37, the first symbol notification control means 71 sets the operation information related to the winning of the first symbol, that is, the operation order of the stop switch 42 for stopping the combination of the first symbols on the active line for the selected composite combination. Inform. Then, the process proceeds to step S38.

  In step S38, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S39. In step S39, is the pressing order of the stop switch 42 detected in step S38 the pressing order related to the winning of the first symbol (the pressing order of the stop switch 42 in which the first symbol combination stops on the active line)? When it is determined whether or not it is determined that the pressing order is related to the first symbol winning, the process proceeds to step S40, and when it is determined that the pressing order is not related to the first symbol winning, the process proceeds to step S41.

  In step S40, the reel stop control means 66 sets a first symbol stop control table for stopping the first symbol combination on the effective line as the stop control table 66b, and proceeds to step S42. On the other hand, in step S41, the reel stop control means 66 sets a second symbol stop control table for stopping the combination of the second symbols on the effective line as the stop control table 66b, and proceeds to step S42.

  Then, the process proceeds from step S40 or step S41 to step S42, and the reel stop control means 66 controls the drive of the motor 32 to control the stop of the reel 31 corresponding to the turned-on stop switch 42. Here, when the process proceeds from step S40 to step S42, the first combination of symbols "bell"-"bell"-"bell" is related to the operated stop switch 42 so as to stop at the active line. The stop position of the reel 31 is determined, and the reel 31 is controlled to stop at the determined position. On the other hand, when the process proceeds from step S41 to step S42, the reel associated with the operated stop switch 42 so that the second symbol combination "bell"-"bell"-"RP" stops at the active line. The stop position of 31 is determined, and the reel 31 is controlled to stop at the determined position.

  Next, proceeding to step S43, 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 S48 (FIG. 7). On the other hand, when it is determined that all the reels 31 have not stopped yet, the process returns to step S38.

  In addition, when the process proceeds from step S35 to step S44, the reel stop control means 66 uses the non-winning table (stop control table 66b that does not stop the combination of symbols corresponding to symbols of any role on the effective line) as the stop control table 66b. ) Is set, and the process proceeds to step S45.

In step S45, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S46. In step S46, the reel stop control means 66 controls to stop the reel 31 related to the stop switch 42 detected in step S45 according to the set non-winning table.
Next, proceeding to step S47, 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 S48. On the other hand, when it is determined that all the reels 31 are not yet stopped, the process returns to step S45.

  When the process proceeds from step S43 or step S47 to step S48, the stop symbol determining means 67 determines whether or not the first symbol combination is stopped on the active line. When it is determined that it has been stopped, the process proceeds to step S49, and when it is determined that it has not been stopped, the process proceeds to step S52. In step S49, the winning processing means 68 performs a payout process (14 medal payout process) based on the fact that the first symbol combination is stopped on the active line. Then, the process proceeds to step S50.

  In step S50, the payout number counting means 69a updates the payout number (total number) of medals during the BB game. Next, proceeding to step S51, the special game control means 69 determines whether or not the number of medals paid out exceeds an upper limit M (360 in the present embodiment). When it is determined that the upper limit value M has been exceeded, the special game control means 69 controls to end the BB game. On the other hand, when it is determined that the upper limit value M is not exceeded, the process returns to step S33, and control is performed so as to continue the first game.

  On the other hand, in step S52, the stop symbol determining means 67 determines whether or not the second symbol combination has stopped on the active line. When it is determined that it has stopped, the process proceeds to step S53, and when it is determined that it has not stopped, the process proceeds to step S50.

  In step S53, the winning processing means 68 performs a payout process (15 medal payout process) based on the fact that the second symbol combination is stopped on the active line. Then, the process proceeds to step S54, and the payout number counting means 69a performs an update process of the payout number (total number) of medals in the BB game. Next, proceeding to step S55, the special game control means 69 determines whether or not the number of medals paid out exceeds an upper limit M (360 in this embodiment). When it is determined that the upper limit value M has been exceeded, the special game control means 69 controls to end the BB game. On the other hand, when it is determined that the upper limit value M is not exceeded, the process proceeds to step S56 (FIG. 8), and control is performed so as to shift to the second game.

  In step S56, the special game control means 69 performs a second game start process. Specifically, an initial value is set for the (remaining) game count X of the second game (in this embodiment, an initial value of the game count X = 12), and an initial value is set for the (remaining) winning count Y. (In this embodiment, the initial value of the number of winning times Y = 8). And it progresses to step S57 and the special game control means 69 is controlled to start the 2nd game of BB game.

  In step S57, the game control means 60 continues to detect whether or not the start switch 41 is turned on. When the start switch 41 is detected, the game control means 60 starts each reel 31 and proceeds to the next step S58. In step S58, the special game control means 69 subtracts 1 from the number of games X of the second game (X = X-1). In the next step S59, the combination lottery means 61 performs a combination lottery. As shown in FIG. 2, only a predetermined combination is selected as a winning combination.

  In the next step S60, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S61. In step S61, the reel stop control means 66 selects the stop control table 66b corresponding to the lottery result of the combination (a predetermined combination table for winning a predetermined combination when a predetermined combination is won, or any combination when a combination is not selected. The stop position of the reel 31 is determined based on the timing when the stop switch 42 is operated in accordance with the non-winning table in which no winning combination is won, and the reel 31 is controlled to stop at the determined position. Then, the process proceeds to step S62.

  In step S62, 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 S63. On the other hand, when it is determined in step S62 that all the reels 31 are not stopped, the process returns to step S60.

  In step S63, the stop symbol determining means 67 determines whether or not the combination of symbols corresponding to the predetermined combination has stopped on the active line (whether or not the predetermined combination has won a prize). If it is determined that the predetermined combination has won, the process proceeds to step S64. On the other hand, when it is determined that the predetermined combination has not won, the process proceeds to step S68.

In step S64, the winning processing means 68 pays out medals corresponding to the winning of the predetermined combination (paying one medal), and proceeds to step S65. In step S65, the payout number counting means 69a updates the payout number (total number) of medals in the BB game, and proceeds to step S66.
In step S66, the special game control means 69 subtracts 1 from the number Y of winning the second game (Y = Y-1). Then, the process proceeds to step S67.

  In step S67, the special game control means 69 determines whether or not the number of medals paid out exceeds the upper limit M (360 in this embodiment). When it is determined that the upper limit value M has been exceeded, the special game control means 69 controls to end the BB game. On the other hand, when it is determined that the upper limit value M is not exceeded, the process proceeds to step S68, and the special game control means 69 determines whether or not the second game end condition is satisfied. In the present embodiment, it is determined that the condition for ending the second game is satisfied when the number of wins for the predetermined role in the second 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 33 to control to start the first game of the BB game. On the other hand, if it is determined in step S68 that it is not yet satisfied, the process returns to step S57, and the special game control means 69 continues the second game.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to embodiment mentioned above, For example, the following various deformation | transformation is possible.
