Description

  The present invention relates to a slot machine in which an RT game is terminated when a predetermined combination wins when executing an RT game in which the winning probability of a replay (re-playing combination) is set higher than that in a normal game. Is.

In a conventional slot machine, a normal game with a replay winning probability of about 1 / 7.3, for example, and an RT (Replay Time) with a higher replay winning probability than for a normal game (for example, about 1 / 1.5) A slot machine provided with a game is known.
Here, during the normal game, a bonus combination (BB, RB, etc.) is won, and when the bonus combination is won, the game shifts to a special game (BB game, RB game, etc.), and the RT game is executed after the special game ends. Such a slot machine is known.
Furthermore, during the RT game, when the combination for ending the RT game (RT game end (punk) combination) wins (when the combination of symbols corresponding to the RT game end combination stops on the active line), the RT There is known a slot machine that controls to end a game (see, for example, Patent Document 1).
JP 2006-223709 A

  However, in the technique of the above-mentioned Patent Document 1, an RT game end combination is drawn by lottery during an RT game, and when the RT game end combination is won and won, the RT game ends with the game, and the next It was a transition from gaming to normal gaming. Therefore, the player cannot predict that the RT game will end soon, and knows that the RT game will end when the RT game finisher wins during the RT game. For this reason, there was a problem that the RT game ended too suddenly.

  Therefore, the problem to be solved by the present invention is to inform the player that the possibility of the end of the RT game is high when the RT game is ended when the predetermined role is won, and then the RT game is It is to end.

The present invention solves the above problems by the following means. The configuration of the corresponding embodiment is shown in parentheses.
According to the first aspect of the present invention, the gaming state includes a first gaming state (non-RT gaming) and a second gaming state (RT1 gaming to RT4 gaming) in which a payout rate is set higher than that of the first gaming state. And when the condition for shifting to the second gaming state (end of BB gaming or RB gaming) is satisfied, the current gaming state (BB gaming or RB gaming) is shifted to the second gaming state. Game state control means for controlling, a plurality of reels displaying a plurality of types of symbols, a stop switch provided corresponding to each of the reels and operated by a player when stopping the reels, and the rotated A lottery drawing means for drawing a lot before the reels stop, and when the reel rotation start command is received (when the start switch 41 is operated), the reel is rotated and the player Reel control means for stopping and controlling the reel at a position corresponding to a result of lottery winning by the winning lottery means when the top switch is operated, and the winning lottery means in the second gaming state A lottery of a combination including one specific combination (SB) is performed, and the gaming state control means wins the first specific combination by the combination lottery means in the second gaming state and corresponds to the first specific combination. When the combination of symbols stops on the active line, control is performed so that a specific game (SB game) is executed for a predetermined number of games (1 game), and the combination lottery means A lottery of a combination including a specific combination (RT game end combination) is performed, and the winning probability (95/100) of the second specific combination in the specific game is the second specific combination in a game other than the specific game. Winning probability (0) The game state control means wins the second specific combination by the combination lottery means in the specific game that has shifted from the second game state, and corresponds to the second specific combination When the combination of symbols stops on the active line, control is performed to end the second gaming state and shift to the first gaming state, and the combination of symbols corresponding to the second specific combination stops on the effective line. If not, control is made to return to the second game state, and the reel control means is a combination of symbols corresponding to the first specific combination in the game in which the first specific combination is won by the combination lottery means. When the stop switch is operated at a timing at which it stops at the active line, the combination of symbols corresponding to the first specific combination is stopped at the active line, and at other timings the stop switch Is operated to stop the reel so that the combination of symbols corresponding to the first specific combination is not stopped on the effective line, and the reel control means wins the second specific combination by the combination lottery means. The game is characterized in that the reel is controlled to stop so that the combination of symbols corresponding to the second specific combination is always stopped on the active line regardless of the timing of operation of the stop switch. .

  According to a second aspect of the present invention, in the slot machine according to the first aspect, a combination of symbols corresponding to the first specific combination when the first specific combination is won by the combination lottery means in the second gaming state. Is provided with notifying means (SB winning notifying means 70a) for notifying the player of information that allows the stop switch to be operated so as not to stop at the active line.

  According to a third aspect of the present invention, in the slot machine according to the first or second aspect, in the gaming state control means, in the second gaming state, a combination of symbols corresponding to the second specific combination is on an effective line. When the specified number of games (100 games) has been reached without stopping, control is made so as to end the second game state and shift to the first game state.

  According to a fourth aspect of the present invention, in the slot machine according to any one of the first to third aspects, the combination lottery means is more than the probability of not winning the second specific combination in the specific game. The lottery is performed so that the probability of winning the second specific combination is higher.

  According to a fifth aspect of the present invention, in the slot machine according to any one of the first to fourth aspects, in the second gaming state, the combination lottery means is the second specific only in the specific game. It is characterized by drawing lots of roles.

(Function)
In the present invention, in the second gaming state, when the first specific combination is drawn and the combination of symbols corresponding to the first specific combination stops on the active line (the first specific combination wins), the specific game Is executed. Then, when the second specific combination is drawn in the specific game, and the second specific combination wins, the second game state is controlled to end. In the second gaming state other than the specific game, the lottery of the second specific combination is not performed or is set to a very low winning probability (for example, 1/65536).

According to the present invention, the process from the second gaming state to the end of the second gaming state has a first stage (winning of the first specific combination) and a second stage (winning of the second specific combination). I am doing so. Thereby, in the second gaming state, it is possible to prevent the second gaming state from being abruptly terminated without any prior notice.
Further, if the winning probability and the winning rate of the second specific combination in the specific game are not set to 100%, it is possible to give the player a chance that the second game state will not end even if the specific game is entered.

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 according to the present embodiment. The game control means 60 of the slot machine 10 is means for controlling the entire slot machine 10 and controls the lottery of the winning combination, the drive control of the reels 31, the payout at the time of winning, and the output of effects. The game control means 60 is provided on a control board (not shown). The game control means 60 is a CPU for performing calculations, a ROM for storing programs necessary for the progress of games and the output of effects, etc. A RAM or the like for temporarily storing data and the like taken in when performing control is provided.

  In the present embodiment, the game control means 60 is illustrated as one, but the present invention is not limited to this, and the main control board having the game control means 60 for controlling the progress of the game and the effect for controlling the output of the effect. A sub-control board having the control means 70 may be provided separately, and the main control board may be configured to transmit information necessary for production output to the sub-control board.

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 operated when the player inserts a stored medal for the game. The bet switch 40 in the present embodiment is a switch dedicated to the insertion of three (max).
The medal slot 43 is a part where the player inserts an actual medal, and inserting a medal from the medal slot 43 has the same role as operating the bet switch 40.

The start switch 41 is a switch operated by the player when starting (all) reels 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.

A motor 32 is 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 a reel control means 64 described later. Here, the reel 31 includes a left reel 31, a middle reel 31, and a right reel 31, and a stop switch 42 that is operated when the left reel 31 is stopped is the left stop switch 42, and when the middle reel 31 is stopped. The stop switch 42 to be operated is the middle stop switch 42, and the stop switch 42 to be operated when stopping the right reel 31 is the right stop switch 42.

  The reel 31 is ring-shaped, and a reel tape on which a plurality of types of symbols (designs constituting a combination of symbols corresponding to the combination) is attached is attached to the outer peripheral surface thereof. FIG. 2 is a diagram showing a symbol arrangement of the reels 31 in the present embodiment. In FIG. 2, symbol numbers are also shown. As shown in FIG. 2, in this embodiment, 21 symbols are arranged at equal intervals for each reel 31.

  FIG. 3 is a view showing the positional relationship between the display window (transparent window) 11 provided on the front mask portion (front door, not shown) of the slot machine 10 and the reel 31. In this embodiment, three reels 31 (left reel 31, middle reel 31, and right reel 31) are provided in parallel in the horizontal direction. Further, each reel 31 is arranged so that three symbols that are continuous in the vertical direction can be seen from the display window 11. Therefore, it is arranged so that a total of nine symbols can be seen from the display window 11 of the slot machine 10.

Further, as shown in FIG. 3, symbol combination lines L <b> 1 to L <b> 5 are provided in a portion including the display window 11 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, a total of five symbol combination lines L1 to L3 in the middle, upper, and lower stages in the horizontal direction, and two symbol combination lines L4 and L5 in the diagonally right-down direction and diagonally right-up direction. Has a symbol combination line.

In addition, the symbol combination line has an effective line and an invalid line.
Here, the “effective line” is a line for winning a winning combination when a combination of symbols corresponding to any of the winning combinations is stopped on that line.
On the other hand, an “invalid line” is a line that is not set as an effective line among symbol combination lines, and even if a combination of symbols corresponding to any combination stops on that line, This is a line that does not give profits (medal payout etc.). In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

The valid line and the invalid line are set according to the number of inserted medals, but in this embodiment, the game is set so that three medals are inserted during any game. In all games, all five symbol combination lines L1 to L5 are set as valid lines, and no invalid lines are set.
The number of medals inserted is not limited to this, and may be one or two. Furthermore, only a part of the five symbol combination lines L1 to L5 may be set as valid lines (the rest are invalid lines) according to the number of medals inserted, the game state, and the like.

Further, in FIG. 1, 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 is arranged on the inner peripheral side of each reel 31 and is a back lamp (not shown) for illuminating from behind the symbols displayed on the reel 31 (three symbols that are continuously visible from the display window 11). ), And an upper lamp and a side lamp (not shown) which are arranged on the front surface of the housing of the slot machine 10 and blink when a winning combination is made.

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 display, a dot display, and the like, and displays various effect images, predetermined information, and the like during the game.

FIG. 4 is a diagram showing the types of combinations (combinations drawn by the combination lottery means 61 described later), the number of payouts, and combinations of symbols in the present embodiment. As shown in FIG. 4, special combinations, small combinations, replays, and RT game end (punk) combinations are provided as combinations.
A combination of symbols corresponding to each combination and the number of payouts at the time of winning are determined. As a result, when all the reels 31 are stopped, when the combination of symbols corresponding to any of the combinations stops on the active line (the combination wins), the number of medals corresponding to the combination is paid out (however, Excluding special roles).

  In the combination, first, the special combination is a combination that shifts from the normal game to the special game. In the present embodiment, as shown in FIG. 3, BB (first type big bonus), RB (regular bonus), and SB (single bonus) are provided as special roles.

  In the present embodiment, the BB includes two types of BBA and BBB. When BB (either BBA or BBB) wins, there is no payout of medals in the game, but the next game shifts to BB game which is one of special games. Furthermore, when the RB wins, there is no payout of medals in the game, but the next game shifts to the RB game which is another one of the special games. These BB games and RB games are games advantageous to the player who can expect to win medals more than normal games by setting the payout rate to exceed 1.

Further, when the SB wins, no medals are paid out in the game, but the SB game is executed only in one game in the next game.
Other special combinations include 2BB (second-type big bonus, also referred to as MB (middle bonus)), which is not provided in this embodiment.

A small role is a role in which a predetermined number of medals are paid out. In this embodiment, there are three types of small roles 1 to 3 and combinations of symbols different for each small role. Is set.
Furthermore, the replay is a re-playing role that allows the re-playing while maintaining the number of medals inserted in the game. In the present embodiment, two types of replay A and replay B are provided as replays. Then, as will be described later, the replay B is set as a combination for shifting the gaming state.

  Furthermore, the RT game end combination is a game that is won when an RT game is won after the end of a special game, which will be described later (more specifically, during an RT1 game, an RT2 game, an RT3 game, or an SB game during an RT4 game). This is the role that the RT game ends (punctures). It should be noted that even if the RT game finisher wins during a non-RT game, there is no transition of the game state.

In each of the above-mentioned combinations, if the combination of symbols corresponding to the combination does not stop on the active line in the game selected for the combination, a combination that is carried over after the next game and a combination that is not carried over are determined. .
BB and RB in special roles are listed as the roles to be carried over. When winning BB or RB, the game is controlled to carry over the winning of BB or RB after the next game in the game until the combination of symbols corresponding to BB or RB stops on the active line when the reel 31 stops. The

  In this way, the winning of BB and RB is carried over, while the roles other than BB and RB (SB, small role, replay, and RT game ending role) are not carried over. When a winning combination other than BB and RB is won in the winning combination, the winning combination is valid only in the game, and the winning combination is not carried over after the next game. In other words, in the game where these winning combinations are won, the reel 31 is controlled to stop so that the combination of symbols corresponding to the winning combination can be stopped (winning) on the active line. Regardless, at the end of the game, the right to the winning role will cease.

  Note that a game that is not won by BB or RB (a game in which the winning of BB or RB is not carried over) is referred to as “non-internal”. Also, in the game before the game, BB or RB is won, but the combination of symbols corresponding to the won BB or RB is not stopped on the active line (not winning) The game in which the winning is carried over) is called “inside”.

  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 insertion slot 43, and operates (turns on) the start switch 41. When the start switch 41 is operated, a signal generated at that time is input to the game control means 60. When the game control means 60 (specifically, the reel control means 64 described later) receives this signal, it 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 11 at a predetermined speed.

  Then, the player presses the stop switch 42 to stop the rotation of the reel 31 corresponding to the stop switch 42 (for example, the left reel 31 corresponding to the left stop switch 42). 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, the reel control means 64 described later) receives this signal, it controls the drive of the motor 32 corresponding to the stop switch 42 and controls the stop of the reel 31 related to the motor 32. I do. When all of the reels 31 are stopped, when a combination of symbols corresponding to any of the combinations stops on the active line (when the winning combination of the combination is awarded), a medal corresponding to the winning combination is paid out. Done.

  As shown in FIG. 1, the game control means 60 includes the following combination 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.

  The role lottery means 61 performs lottery of a role (the above-mentioned special role, small role, replay, and RT game end 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 generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). The random number is, for example, a random number for which the counter that performs 1 count at 200 n (nano) sec continues to count as a cycle in the range of 0 to 65535, and continues to count the random number while the slot machine 10 is powered on. .

  The random number extraction means extracts the random number generated by the random number generation means at a predetermined time, in the present embodiment, when the start switch 41 is operated (turned on) 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 winning area of the small combination 1, it is determined that the small combination 1 is won, and when it belongs to the non-winning area, it is determined to be non-winning.

  The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. 5-7 is a figure which shows the part lottery table 62 (62A-62E) in this embodiment. The role lottery table 62 is provided for each gaming state. Each of the winning lottery tables 62 has a predetermined range of lottery areas. The lottery areas are divided into a winning area and a non-winning area of each winning combination, and a winning probability that a lottery is set in advance is set. It is set to a predetermined ratio so that

First, the “gaming state” of the present embodiment includes non-RT games (games that are not inside of normal games), RT5 games (games that are inside), RT1 games, RT2 games, RT3 games and RT4 games, and special games. (BB game, RB game, and SB game).
The combination lottery table 62A is a combination lottery table 62 used in non-RT games (non-internal games of normal games).

  In the role lottery table 62A, special roles (BBA, BBB, RB, and SB), small roles 1 to 3, and Replay A and Replay B (single) winning, and non-winning of the role are provided. ing. In addition, although it is possible to set the special combination and the small combination to be won simultaneously, or to set a plurality of different small combinations to be selected, in this embodiment, only a single winning combination is provided. Further, in the combination lottery table 62A, the RT game end combination is not selected. Since the winning probability of each combination shown in FIG. 5 is set, the non-winning probability in the winning lottery table 62A is about 70/100.

  The role lottery table 62B is a role lottery table 62 used in RT5 games (games inside). The combination lottery table 62B is different from the combination lottery table 62A in that a special combination is not lottery. That is, only a small combination and a replay are drawn. In addition, the winning probability of Replay A is slightly different from the role lottery table 62A.

Furthermore, the role lottery table 62C1 shown in FIG. 6 is the role lottery table 62 used in the RT1 game. The combination lottery table 62C1 differs from the combination lottery table 62A only in the winning probabilities of Replay A and Replay B, and is otherwise the same as the combination lottery table 62A.
In the winning lottery table 62C1, the winning probability of the replay A is 1 / 1.5, which is set higher than the winning lottery table 62A. The winning probability of Replay B is set to 1/300. In the combination lottery table 62C1, since the winning probability of the replay A is set higher, the non-winning probability is lower than that of the combination lottery table 62A.

  Further, the role lottery table 62C2 is a role lottery table 62 used in the RT2 game and the RT4 game. The combination lottery table 62C2 differs from the combination lottery table 62C1 only in the winning probability of the replay B, and is otherwise the same as the combination lottery table 62C1. The winning probability of Replay B in the combination lottery table 62C2 is set lower than that in the combination lottery table 62C1.

  The role lottery table 62C3 is a role lottery table 62 used in the RT3 game. The combination lottery table 62C3 is different from the combination lottery table 62C1 only in the winning probability of Replay B, and is otherwise the same as the combination lottery table 62C1. The winning probability of Replay B in the combination lottery table 62C3 is set lower than the combination lottery table 62C1 and higher than the combination lottery table 62C2.

  Furthermore, the role lottery table 62D shown in FIG. 7 is a role lottery table 62 used in the BB game and the RB game. In the role lottery table 62D, only the small role 1 to the small role 3 are drawn. In particular, the winning probability of the small combination 3 is set to be extremely high as 1 / 1.1. Thereby, in the BB game and the RB game in which the winning lottery table 62D is used, almost every game small role 3 wins and the non-winning probability is about 4/100, which is a low probability.

  Furthermore, the role lottery table 62E is a role lottery table 62 used in the SB game. In the combination lottery table 62E, a small combination 1 to a small combination 3, replay A, replay B, and RT game end combination are selected. In addition, the winning probabilities of the small combination 1 to the small combination 3, replay A, and replay B during the SB game are set to be the same as the winning probability in the gaming state immediately before the SB game transition. For example, when a transition is made from a non-RT game to an SB game, the winning probability of Replay A is set to 1 / 7.3, and the winning probability of Replay B is set to 1/1000. Similarly, when a transition is made from RT1 game to SB game, the winning probability of Replay A is set to 1 / 1.5, and the winning probability of Replay B is set to 1/300. When the RT2 game or the RT4 game is shifted to the SB game, the winning probability of the replay A is set to 1 / 1.5, and the winning probability of the replay B is set to 1/830. Furthermore, when the game is shifted from the RT3 game to the SB game, the winning probability of Replay A is set to 1 / 1.5, and the winning probability of Replay B is set to 1/670. Further, in the SB game, the non-winning probability is set to 1/100, and the winning probability of the RT game end combination is set high because the non-winning probability is set low.

Returning to FIG.
In the game until the combination of symbols corresponding to BB or RB is stopped on the active line (until BB or RB wins), the special role winning carry-over means 63 is BB or RB. It is controlled to carry over the winning of the game after the next game.
A winning flag 63a for storing the winning of BB and RB is provided. For example, when winning of BB, the winning flag 63a related to BB is turned on and maintained until BB wins, and BB wins. When it is turned off at that time.

  First, the reel control means 64 controls to start the rotation of all (three) reels 31 when the start switch 41 is operated. Further, the reel control means 64 determines a stop position determination table, which will be described later, based on the winning lottery result 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 with reference to 65, and the motor 32 is driven and controlled to stop the reel 31 at the determined position.

  For example, the reel control means 64 controls to stop the reel 31 so that the combination of symbols corresponding to the winning combination can be stopped on the effective line within the range of the stop control of the reel 31 in the game won for the winning combination. The reel 31 is controlled to stop so that the combination of symbols corresponding to the other combinations is not stopped on the effective line.

  Here, “within the range of stop control of the reel 31” means within the range of the amount of rotation of the reel 31 (the number of moving symbols) from the moment when the stop switch 42 is operated until the reel 31 actually stops. In the present embodiment, the number of moving symbols from the symbol at the moment when the stop switch 42 is operated is set within 4 symbols (within 5 symbols including the symbol at the moment when the stop switch 42 is operated).

  As a result, when any of the symbols within the range of the stop control of the reel 31 counted from the symbol at the moment when the operation of the stop switch 42 is detected is a symbol to be stopped on the effective line, the stop switch 42 is operated. When that happens, the symbol is controlled to stop at the active line.

  That is, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated at the time of winning the winning combination, the reel 31 stopping control is performed when the reel 31 stops when the symbol related to the winning winning combination does not stop on the effective line. By controlling the rotational movement of the reel 31 within the range, the symbol related to the winning combination is controlled so as to be stopped on the effective line as much as possible.

  Conversely, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated, if the symbol combination corresponding to the winning combination is stopped on the effective line, the reel 31 is stopped when the reel 31 is stopped. By controlling the rotational movement of the reel 31 within the range of 31 stop control, the combination of symbols corresponding to the winning combination is controlled so as not to stop on the effective line.

  The stop position determination table 65 is provided corresponding to each lottery result of the combination by the combination lottery means 61 (one for each combination lottery result), and the moment when the stop switch 42 is operated. The stop position of the reel 31 with respect to the position of the reel 31 is determined.

The stop position determination table 65 includes the following BB table and the like.
The BB table is used on condition that the BB is won in the game, or the BB is won 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 corresponding symbol combination is stopped on the effective line and the symbol combination corresponding to the role other than BB is not stopped on the effective line.

  The RB table is used on condition that the RB has been won in the game, or that the RB has been won before the game and the game has not been won. "Is replaced with" RB ".

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

  The small role 1 table, the small role 2 table, the small role 3 table, the replay table, and the RT game end combination table are the same as the above SB table, and “SB” in the SB table is changed to “small role 1”, This is equivalent to “small role 2”, “small role 3”, “replay”, and “RT game end role”.

Further, when winning a small combination 1 to a small combination 3 or a replay A or a replay B in a game in the inside, the special combination winning carry-over winning table is used.
The special role winning overtime winning table is used in the game in which the winning of the special role (BB or RB) is carried over in the game winning the small role 1 to 3 or Replay A or Replay B. Priority is given to stopping the combination of symbols corresponding to the small part 1 to small part 3 or replay A or replay B won in the active line, and the small part 1 to small part 3 or replay A or If the symbol combination corresponding to Replay B cannot be stopped on the active line, then the reel 31 stop position is set so that the symbol combination corresponding to the special combination carrying over the winning is stopped on the active line. Is stipulated.

Further, when the combination of symbols corresponding to the special combination carrying over the winning cannot be stopped on the active line, the reel 31 is stopped so that the combination of symbols corresponding to any combination is not stopped on the effective line. The combination of symbols is defined.
It is also possible to perform control so that the special combination that has won the prize is given a higher priority than the small combination that has been won in the game.

  In addition, the non-winning table is used in a game in a non-internal game or a special game, and a combination of symbols corresponding to any combination is not stopped on the active line. It defines the combination of time symbols.

Next, the relationship between the symbol arrangement of the reels 31 and stop control will be described.
As shown in FIG. 2, in all the reels 31, the “bell” symbols are arranged at intervals within 5 symbols. As a result, the reel control means 64 can always stop the “bell” symbol on the desired effective line, regardless of the moment when the reel 31 is positioned and the stop switch 42 is operated. Therefore, when winning the small combination 3, the reel control means 64 can always stop the combination of symbols corresponding to the small combination 3 ("bell"-"bell"-"bell") on the active line. .

  This is also true for the “RP” symbol. As shown in FIG. 2, in all the reels 31, “RP” symbols are arranged at intervals of 5 symbols or less. As a result, the reel control means 64 can stop the symbol “RP” on a desired effective line, regardless of which moment the reel 31 is positioned and the stop switch 42 is operated. Therefore, when the replay A is won, the reel control means 64 can always stop the combination of symbols corresponding to the replay A (“RP”-“RP”-“RP”) on the active line.

  Furthermore, since the “RP” symbol of the left and middle reels 31 and the “bell” symbol of the right reel 31 are both arranged within an interval of 5 symbols, the reel control is performed when Replay B is won. The means 64 can always stop the combination of symbols corresponding to the replay B (“RP”-“RP”-“bell”) on the active line.

  In the middle reel 31, the symbols “cherry” are arranged at intervals of 5 symbols or less. As a result, the reel control means 64 can stop the “cherry” symbol on the desired effective line regardless of which moment the stop switch 42 is operated when the middle reel 31 is positioned. Further, as described above, the “bell” symbols of the left and right reels 31 are arranged at intervals of 5 symbols or less. Therefore, when the RT game end combination is won, the reel control means 64 always stops the combination of symbols corresponding to the RT game end combination (“bell”-“cherry”-“bell”) on the active line. Can do.

  On the other hand, “Red 7”, “Blue 7”, “Watermelon”, “Black BAR” on the right reel 31, “White BAR” on the left reel 31, “Plum” on the middle reel 31, and “Cherry” on the left reel 31 About each of these, the space | interval is arrange | positioned exceeding 5 designs. Thus, when BBA, BBB, RB, SB, small role 1 and small role 2 are won, if the stop switch 42 is not operated at the timing when the symbol corresponding to the winning role stops on the active line, it corresponds to the winning combination The combination of symbols to be played does not stop at the active line.

Returning to FIG.
The stop symbol determination means 66 determines 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 determination means 66 determines a symbol on the effective line by detecting, for example, an angle or the number of steps when the motor 32 is stopped.
However, when the stop switch 42 is operated and the stop position is determined using the stop position determination table 65, the stop symbol determination means 66 determines the stop symbol regardless of whether or not the reel 31 has stopped. It is possible.

  The payout means 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 determination unit 66 and the winning combination is won. In addition, a predetermined number of medals are paid out to the player in accordance with the winning combination, or processing such as credit addition is performed.

The special game control means 68 controls the start of the special game, the progress of the game during the special game, and the end of the special game.
During a normal game, when the symbol combination corresponding to BBA or BBB stops on the active line, a BB win is made and the special game control means 68 controls to start the BB game from the next game.
In the BB game, the lottery of the combination is performed using the above-described combination lottery table 62D. As a result, during the BB game, the winning probability of the small role 3 is increased.

Also, in this embodiment, as a BB game end condition, the number of medals paid out during the BB game is a predetermined number (435 when BBA wins and shifts to BB game, BBB wins and BB It is set to be 240) or more when the game is shifted to the game.
For this reason, the special game control means 68 counts the number of medals paid out during the BB game, keeps updating the number of medals paid out for each game, and the counted number of paid-outs exceeds the predetermined number. If it is determined that the BB game end condition is satisfied, it is determined.

  Similarly, when the combination of symbols corresponding to RB stops on the active line during the normal game, the special game control means 68 wins an RB, and the special game control means 68 starts the RB game from the next game. Control to do. In the RB game, in the same manner as in the BB game, the lottery of the combination is performed using the combination lottery table 62D.

Further, in the present embodiment, the RB game end condition is set such that the winning number of the winning combination in the RB game is 8 times or the game number is 12 times.
For this reason, the special game control means 68 counts the number of winnings and the number of games of the winning combination in the RB game, keeps updating these games, and counts the number of winning of the winning combination or the number of games. When it is determined that the value has been reached, it is determined that the RB game end condition is satisfied.

  Furthermore, when the combination of symbols corresponding to SB stops on the active line during the normal game, the special game control means 68 wins an SB, and the special game control means 68 receives the next game (only one game). ) And control to execute the SB game. In the SB game, a winning lottery is performed using the winning lottery table 62E. Then, the special game control means 68 determines that the SB game end condition is satisfied when the game (one game) is ended regardless of whether or not a winning combination in the SB game has been won.

The gaming state control means 69 is a means for controlling transition between various gaming states provided in the present embodiment.
As described above, the gaming state of the present embodiment includes a non-RT game (non-internal game), an RT5 game (internal game), an RT1 game, an RT2 game, an RT3 game, and an RT4 game (replay). Games with a high winning probability) and special games (BB games, RB games, and SB games).

FIG. 8 is a diagram for explaining the transition between the game states.
In FIG. 8, first, when the power of the slot machine 10 is turned on, the gaming state control means 69 controls to set the gaming state to a non-RT game. When the BB or RB is won in the non-RT game and the BB or RB won in the game does not win, the game state control means 69 changes the game state from the next game to the RT5 game (inside). Control to shift to.

  In the RT5 game, when the selected BBA, BBB, or RB wins, the game state control means 69 controls to shift to the BB game or the RB game, respectively. Note that when the BB or RB wins in the game won for the BB or RB, the game state control means 69 controls to shift to the BB game or the RB game, respectively, without going through the RT5 game. Replay B is also drawn in RT5 games, but even if Replay B wins in RT5 games, there is no transition to the gaming state.

  When the BBA wins and shifts to the BB game and the payout number reaches 435 or more, the BB game is terminated, and the game state control means 69 controls to shift from the next game to the RT1 game. Also, when the BBB wins and shifts to the BB game and the payout number becomes 240 or more, the BB game is terminated, and the game state control means 69 controls to shift from the next game to the RT2 game. To do. Furthermore, when the RB wins and shifts to the RB game and the number of winning of the combination reaches 8 times or the number of games reaches 12, the RB game is ended, and the game state control means 69 Control is performed so as to shift from the game to the RT3 game.

In the RT1 game to the RT3 game, the lottery of the combination is performed using the combination lottery tables 62C1 to 62C3. However, as shown in FIG. 6, each of these RT games is different only in the winning probability of the replay B.
Note that the RT1 game to the RT3 game (and the RT4 game described later) are games in which the payout rate is set higher than that of the non-RT game. Here, the payout rate will be described.

First, in RT1 game, when the special combination and replay B are excluded, the expected value of the number of medals paid out per game is
1/50 x 4 (Small 1) + 1/30 x 6 (Small 2) + 1/10 x 12 (Small 3) + 3 x 1 / 1.5 (Replay A)
≒ 3.48 (sheets)
It becomes.
Note that the calculation is performed on the assumption that three medals are paid out when the replay A is won. In the present embodiment, in order to simplify the calculation of the expected value, the winning combination is always won when winning the winning combination (winning rate 100%).

Therefore, the expected value of the difference number (increase / decrease value) of medals per game is
3.48 (expected value of payout number) −3 (number of input sheets) = + 0.48 (sheets)
It becomes.
Therefore, since the expected value of the difference number per game is a positive value, the game state is such that medals gradually increase as the game progresses. That is, it becomes a gaming state advantageous for the player.

Also, the payout rate is
3.48 / 3 = 1.16
And exceeds 1.
When the expected value of the difference number per game is ± 0 and when the payout rate is 1, the number of medals inserted and the number of payouts (expected value) are the same value, and the game progresses. The game state is such that medals do not increase or decrease.
The above applies to RT2 games, RT3 games, and RT4 games.

On the other hand, in non-RT games, when the special combination and replay B are excluded, the expected value of the number of medals paid out per game is
1/50 x 4 (small role 1) + 1/30 x 6 (small role 2) + 1/10 x 12 (small role 3) + 3 x 1 / 7.3 (replay A)
≒ 1.89 (sheets)
It becomes.

Therefore, the expected value of the difference number (increase / decrease value) of medals per game is
1.89 (expected value of payout number) −3 (number of inserted sheets) = − 1.11 (sheets)
It becomes.
Therefore, since the expected value of the difference number per game is a negative value, the game state is such that medals gradually decrease as the game progresses. That is, the gaming state is disadvantageous for the player.

In addition,
1.89 / 3 = 0.63
Becomes less than 1.
In the RT5 game (inside), the winning probability of Replay A is only slightly low, so that the expected value of the difference number per game is a negative value as described above.
Therefore, in the RT5 game (inside), it is advantageous for the player to win the winning BB or RB as soon as possible.

The game state control means 69 continues to determine whether or not the end conditions of these RT games are satisfied during the RT1 game to the RT3 game. As the end conditions of these RT1 games to RT3 games in this embodiment,
(1) 100 games have been consumed,
(2) Winning BB or RB,
(3) Three points are set for winning the RT game end combination.

When the number of games has been exhausted to 100 games, the game state control means 69 controls to end the RT game with the game and shift from the next game to a non-RT game.
In addition, when BB or RB is won, the game state control means 69 controls to end the RT game with the game and shift from the next game to the RT5 game (inside).
Furthermore, when the RT game end combination wins, the game state control means 69 controls to end the RT game with the game (SB game) and shift from the next game to the non-RT game.

  Here, as shown in FIG. 6, during the RT1 game to the RT3 game, the RT game end combination is not drawn. However, in these games, SB is drawn. Since the winning probability of SB is 1/30, it is considered that the player wins about three times until 100 RT games are consumed.

  When the SB wins in the RT game, the SB game is executed in the next game. In the SB game, as shown in FIG. 7, the RT game end combination is drawn by lottery. When the RT game end combination wins in this SB game, after the end of the SB game, the game shifts to the non-RT game without returning to the RT game. On the other hand, even if SB is won, the SB game is not executed unless the SB wins. Further, when the RT game end combination is not won in the SB game (including winning of a combination other than the RT game end combination), the game state control means 69, after the end of the SB game, before the SB game is executed. Control to return to RT game.

Further, in the RT1 game to the RT3 game, the replay B is lottery (see FIG. 6). Then, when Replay B wins / wins in these RT games, the game state control means 69 controls to shift from the next game to the RT4 game as shown in FIG.
Further, the game state control means 69 continues to determine whether or not the RT4 game end condition is satisfied during RT4. As an end condition of RT4 game in this embodiment,
(1) Having won BB or RB,
(2) Two things are set that the RT game end combination has won.

That is, unlike RT1 games to RT3 games, there is no limit on the number of games (100 games). Therefore, the RT4 game is continued indefinitely until BB or RB is won or the RT game end combination is won.
As shown in FIG. 8, when BB or RB is won in RT4 game, the game state control means 69 controls to shift to RT5 game. Even if SB is won, if the SB does not win, the SB game is not executed. On the other hand, when the winning SB wins, the SB game is executed, but when the RT game finisher wins in this SB game, after the end of the SB game, the game shifts to the non-RT game without returning to the RT4 game. In addition, when the RT game end combination is not won in the SB game, the game state control means 69 controls to shift to the RT4 game after the SB game ends.

As shown in FIG. 5, replay B is drawn in lots even during non-RT games. When the replay B is won during the non-RT game and the replay B wins, as shown in FIG. 8, the game state control means 69 shifts to the RT4 game as in the RT1 game. Control.
In addition, SB is drawn in lots during non-RT games. When SB is won during non-RT game and SB wins, SB game is executed in the next game. In both cases when the RT game end combination is won in the SB game and when the combination is not won, the game state control means 69 controls to shift to the non-RT game again after the SB game ends.

In FIG. 1, the effect control means 70 controls the output of effects from the lamp 21, the speaker 22, and the image display device 23 described above.
The effect control means 70 selects an effect 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 70 selects one effect pattern by lottery using software random numbers after the role lottery means 61 has been drawn at the start of the game.

In addition, a plurality of types of production patterns are provided according to the winning combination. For example, a plurality of types of effect patterns are provided for each special role winning, small role winning, replay winning, non-winning, and the like.
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 70 controls to output an effect from the effect output device at a predetermined timing according to the selected effect pattern.

  The effect control means 70 includes SB winning notification means 70a. The SB winning notification means 70a indicates that, in the RT1 game, the RT2 game, the RT3 game, and the RT4 game, when winning the SB, the fact that the SB is won, more specifically, information for avoiding the winning SB winning. Is notified to the player.

  As a notification method, the image aimed at the left reel 31 is displayed on the image display device 23 as an image. For example, “Aim at the“ Blue 7 ”block on the left reel 31! ". Here, “the block of“ blue 7 ”” refers to a range from No. 15 to No. 17 in the left reel 31 of FIG. That is, it notifies that the left stop switch 42 should be operated so that the left reel 31 stops at the position shown in FIG. When the left stop switch 42 is operated at this position, the third “white BAR” symbol on the left reel 31 does not stop at the effective line (in the display window 11). In other words, SB winning can be avoided in the game won for SB.

When the SB is won, the above-described SB table is used. When the stop position determination table 65 is used, the combination of symbols corresponding to the SB stops as much as possible within the range of the stop control of the reel 31. Thus, the reel 31 is controlled to stop.
As described above, when the left stop switch 42 is operated at the moment when the symbols from No. 15 to No. 17 are located in the display window 11, the maximum number of symbols to be moved from that position is four symbols. The symbols on the reel 31 can be drawn into the effective line only to the position where the symbols 19 to 0 stop in the display window 11. Therefore, the third “white BAR” symbol is not drawn into the active line.

As described above, in the RT1 game to the RT4 game, when the SB is won, the SB winning can be avoided by operating the left stop switch 42 according to the notification.
This notification is always performed in the RT1 game to the RT4 game when the SB is won.

  Further, even if the “white BAR” symbol stops on the effective line when the left reel 31 stops, the middle stop switch 42 prevents the “plum” symbol from stopping on the effective line when the middle reel 31 stops. If the right stop switch 42 is operated so as not to stop the “blue 7” symbol on the active line when the right reel 31 is stopped, it is possible to avoid winning the SB.

  In addition, during non-RT games, even if SB is won, the above notification is not performed. Therefore, during a non-RT game, there is a case where the SB wins by chance and the SB game is executed.

  In the slot machine 10 described above, during the non-RT game, the player plays the game while waiting for the winning of BB, RB, or Replay B. And when BB or RB is won and won, it is possible to shift to a BB game or an RB game that is advantageous to the player. Furthermore, after the end of these BB games or RB games, it is possible to shift to any of RT1 games to RT3 games according to the winning symbol. In addition, when RT1 game to RT3 game wins Replay B and Replay B wins, it shifts to RT4 game. Similarly, when the replay B is won in the non-RT game and the replay B wins, the game shifts to the RT4 game. Even if Replay B wins during the RT4 game, the game state does not change.

Since the RT1 game to the RT4 game are games in which the payout rate exceeds 1, the player can increase the number of owned medals as the game progresses.
Further, in the RT1 game to the RT3 game, the probability of being able to shift to the RT4 game is different. This is because the winning probabilities of Replay B are different as shown in FIG. The probabilities of switching from RT1 game, RT2 game, and RT3 game to RT4 game during 100 games are set to about 33%, about 12%, and about 15%, respectively.

  Furthermore, when SB is won in RT1 game to RT4 game, that fact and information for avoiding the winning are notified, so if the left stop switch 42 is operated according to the notification, execution of SB game is avoided. can do. That is, it is possible to avoid the transition to the SB game and the RT game ending combination winning a prize. Thereby, in the RT1 game to the RT4 game, if the SB winning is avoided, it is possible to prevent the RT1 game to the RT4 game from ending due to the RT game ending role winning. Therefore, if the SB winning is continuously avoided, the RT1 game to the RT3 game can be continued in the RT1 game to the RT3 game until the number of games is exhausted to 100 games. On the other hand, in the RT4 game, if the SB winning is continuously avoided, the RT4 game can be continued until BB or RB is won.

  If the stop operation timing of the stop switch 42 is wrong during the RT1 game to the RT4 game and the SB is won, the possibility that the RT1 game to the RT4 game will end is increased and the game ends. Whether or not it depends on luck. In the SB game, as shown in FIG. 7, the RT game end combination is won with a predetermined probability according to the game state before the SB game transition. In addition, when winning the RT game winning combination, as described above, winning cannot be avoided and must be won. Therefore, when the RT game end combination is won, it is determined that the RT1 game to the RT4 game are ended with the SB game. On the other hand, when the SB game is executed but the RT game end combination is not won, after the end of the SB game, it is possible to return to the RT1 game to the RT4 game again.

As described above, in the RT1 game to the RT4 game, the RT game is not ended, and the RT game is ended only after the SB is won or won, instead of the transition to the non-RT game. You can know that there is a fear. That is, in the RT1 game to the RT4 game, the lottery for the RT game end combination is not drawn (the winning probability of the RT game end combination is 0).
Furthermore, since winning can be avoided at the time of winning the SB, it is possible to avoid the execution of a game (SB game) having a high probability of ending the RT game. In the RT1 game to the RT4 game, it is possible to give the player a sense of security that the RT game will not end unless the SB wins.

Furthermore, even if the SB is won by mistake in the RT1 game to the RT4 game and the SB game is executed, the RT game is set so as not to end when the RT game ending role is non-winning. Measures have been taken to rescue the elderly.
In this way, the first stage (SB prize) and the second stage (RT game end prize) are provided before the RT game is finished, so there is no precaution as in the conventional slot machine. It is possible to eliminate the sudden termination of the RT game (suddenly having a small role for ending the RT game).

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to embodiment mentioned above, The following various deformation | transformation are possible.
(1) When winning an SB in RT1 game to RT4 game, it is possible to control not to notify the winning of SB. For example, as in this embodiment, for each game, a specific reel 31 is set so as to avoid winning SB if it is pushed to stop at a specific position, and the player is always in that position. If the player is forced to push the SB, the player can avoid winning the SB even if no notification is given when the SB is won.

(2) The winning probability of SB in RT1 game to RT4 game is not limited to the value shown in the present embodiment, but differs depending on how much the SB winning winning is performed during RT game. It is.
(3) The winning probability of the RT game end combination during the SB game is not limited to the value shown in the present embodiment, and various changes can be made. For example, if the relief rate for RT game punctures is to be increased even after shifting to SB game, the winning probability of the RT game end combination may be set low.

  (4) In this embodiment, when the SB is won, the reel 31 is stopped at a specific position to avoid winning the SB. However, the present invention is not limited to this, and as a condition for winning the SB, the pressing order of the stop switch 42 is set in advance, and if the pressing order of the specific stop switch 42 is pressed, stop control is performed so that the selected SB does not win, If the pressing order is other than that, it is possible to stop control so that the SB wins.

  (5) SB winning probabilities may be set differently for a plurality of RT games. For example, the winning probability of SB may be set to 1/50 for RT1 games, 1/30 for RT2 games, 1/20 for RT3 games, 0 for RT4 games, and the like. Furthermore, a plurality of types of SB games may be provided, and the winning probabilities of the RT game end combination may be set differently. For example, the winning probabilities for RT game end roles are 17/100 for SB games transferred from RT1 games, 10/100 for SB games transferred from RT2 games, 5/100 for SB games transferred from RT3 games, and from RT4 games In the migrated SB game, it may be set to 1/100.

  (6) The notification content at the time of winning the SB is any information as long as the information that can operate the at least one stop switch 42 is notified so that the combination of symbols corresponding to the SB is not stopped on the effective line. There may be. For example, except for the above embodiment, “Don't stop the symbol of“ white BAR ”on the left reel 31! Or a notification that the symbol “black BAR” or “white 7” at a position sufficiently distant from “white BAR” should be stopped.

  (7) As a specific game of the present invention, an SB game is provided in this embodiment. However, the present invention is not limited to this, and any game may be used as long as it is executed one or more times and the second specific combination (RT game end combination) is selected.
