Description

  The present invention makes it possible to stock the winnings of a plurality of special roles (BB, RB, etc.), and controls to increase the payout rate in subsequent games according to the number and type of special roles that have been stocked. It relates to slot machines.

  In the conventional slot machine, as a winning combination, a special role (such as a big bonus or a regular bonus) for shifting to a special game (for example, a big bonus game or a regular bonus game) advantageous to the player, A small role or replay is known. And when winning a small combination or replay, the right to win the winning combination ends with the game regardless of whether the small combination or replay won in the game has won. On the other hand, when a special role is won, the special role is maintained until the special role is won (it is carried over after the next game).

Here, each time a special role is won, stocks are made so that the selected special role does not win (including cases where multiple special roles are stocked), and a predetermined condition (special role release condition) is satisfied. There is known a slot machine that is controlled so that a special combination (including a plurality of special combinations) that has won a prize can be won (see, for example, Patent Document 1).

Furthermore, the replay is a re-playing role that allows the re-playing while maintaining the number of medals inserted in the game.

Further, as shown in FIG. 2, combinations of symbols of the reel 31 corresponding to the various kinds of roles described above are determined in advance. Note that “any” in the small part 1 means that any symbol may be used.
When all the reels 31 are stopped, if the combination of symbols corresponding to any of the combinations stops on the active line, the winning combination of the combination is won. For example, when “Red 7”-“Red 7”-“Red 7” stops on any active line, BB1 wins.

In each of the above-mentioned combinations, if the combination of symbols corresponding to the combination in the game won for the combination does not stop on the active line, it is carried over after the next game (the winning combination is maintained after the next game) and , A role that is not carried over is defined.
Special roles (BB, MB, and RB) can be cited as carry-overs. When the special combination is won, when the reel 31 is stopped, it is controlled so that the special combination is carried over from the next game onward until the combination of symbols corresponding to the selected special combination stops on the active line. .

  As described above, the winning of the special role is carried over, but the roles other than the special role (small role and replay) are not carried over. When a role other than the special role is won in the lottery of the role, the winning role is valid only in the game, and the winning 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.

A game in which a special role is not won (a game in which a special role is not carried over) is referred to as “non-inside”. In addition, the combination of symbols corresponding to the selected special combination is not stopped on the active line (not winning) in the game (the special combination is selected) The game that is carried over) is called “inside”. In the present invention, “internal game” includes a game won in a special role.
In addition, as will be described later, in the present embodiment, it is set so that the winning of the special combination can be carried over for each number of medals inserted. In this case, for example, if a special combination is won when the number of inserted medals is 1, a game with a single medal inserted after that becomes an internal game, but other medals inserted (2 (Or 3), if the winning of the special role is not carried over, the game with the other number of inserted medals is a non-internal game.

  At the start of the game, the player operates the bet switch 40 to insert a previously stored medal, or inserts a medal from the medal insertion slot 43, and turns on the start switch 41. When the start switch 41 is operated, an effective line is set and 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 up and down in the display window at a predetermined speed.

  Then, the player presses each stop switch 42 to stop the rotation of each reel 31. 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 the reels 31 are stopped, when the combination of symbols on the reel 31 stopped on the effective line matches a predetermined combination of symbols of the combination, The medals are paid out according to the winning combination.

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

  The random number generation means 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 power of the slot machine 10 is turned on. .

  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 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 small role 1 winning area, it is determined that the small role 1 is selected, and if 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. FIG. 3 is a diagram showing the combination lottery tables 62A to 62C (used during normal games) of the present embodiment. The normal lottery table 62 in the normal game is provided for each inserted number of medals, and has a unique special lottery table 62 for each non-inside / inside.

  Each combination lottery table 62 has a predetermined range of lottery areas. The lottery area is divided into a winning area and a non-winning area for each combination, and the winning combination has a predetermined winning probability. It is set to a predetermined ratio so that

  In FIG. 3, a role lottery table 62A is a role lottery table 62 that is used when the number of inserted medals is one, and a role lottery table 62A that is used when the medal is not inside is BB1, MB1, RB1, small Each winning area and non-winning area of the winning combination 1, small winning combination 2, small winning combination 3, and replay are provided. On the other hand, in the combination lottery table 62A used in the inside, the winning area of the special combination (BB1, MB1, RB1) is set as a non-winning area. That is, when the number of inserted medals is one, if any one of BB1, MB1 or RB1 is won from the non-internal state and becomes internal, then the selected BB1, MB1 or RB1 wins. Until BB1, MB1 and RB1 are not drawn.

  The role lottery table 62B is a role lottery table 62 used when the number of inserted medals is two. The role lottery table 62A used when the medal is not inside is BB2, MB2, RB2, small role 1 Each winning area and non-winning area for small combination 2, small combination 3, and replay are provided. On the other hand, in the combination lottery table 62B used in the inside, the winning area of the special combination (BB2, MB2, RB2) is set as a non-winning area.

  Furthermore, the role lottery table 62C is a role lottery table 62 used when the number of inserted medals is 3, and the role lottery table 62C used when the medal is not inside is BB3, MB3, RB3, small role. Each winning area and non-winning area is provided for 1, 2, 2, and Replay. On the other hand, in the combination lottery table 62C used in the inside, the winning area of the special combination (BB3, MB3, RB3) is set as a non-winning area.

  In FIG. 3, the winning areas of the respective combinations are illustrated in the combination lottery tables 62A to 62C to approximately the same level, but actually, the winning probabilities differ depending on the number of inserted medals. In this embodiment, the winning probability of replay is uniformly set to 1 / 7.3 regardless of the number of medals inserted.

  On the other hand, the winning probabilities for the special role and the small role are approximately 2X (2) when the winning probability when the number of inserted medals is 1 is X. The winning probability when the number of inserted medals is 3 is set to about 3X (3 times). For example, if the winning probability of BB1 (BB winning probability when the number of inserted medals is 1) is set to 1/900, the winning probability of BB2 (BB when the number of inserted medals is 2) The winning probability) is set to about 1/600, and the winning probability of BB3 (BB winning probability when the number of inserted medals is 3) is set to about 1/300. The same applies to other special roles and small roles.

  However, the present invention is not limited to this, and it is possible to set the winning probabilities of the special combination and the small combination to be the same no matter how many medals are inserted. Conversely, it is possible to set so that the winning probability of winning combination becomes lower as the number of inserted medals increases.

  FIG. 4A is a diagram showing a role lottery table 62D used during BB games and RB games. The winning lottery table 62 </ b> D is provided with a winning area and a non-winning area for the small roles 1 to 3. Particularly, the winning probability of the small combination 3 is set to be high (for example, 1 / 1.1). Note that the winning probabilities of the small combination 1 and the small combination 2 are the same as those in the normal game.

FIG. 4B is a diagram showing a role lottery table E used during the MB game. In the winning lottery table 62E, a replay winning area (winning probability is 1 / 7.3) and a non-winning area are provided (no small role is drawn).
During BB games, RB games, and MB games, the number of inserted medals is set to 3 (the number of inserted medals cannot be played with 1 or 2 medals). Has been.

  Further, FIG. 4C is a diagram showing the role lottery tables 62F, 62G, and 62H used during the RT game, where the number of inserted medals is 1, 2, and 3, respectively. During the RT game, the replay winning probability is set higher than that during the normal game (the role lottery tables 62A to 62C shown in FIG. 3) (the winning probability of the role other than the replay is the same as the normal game). is there). Specifically, the winning probability of replay in the part lottery tables 62A to 62C is set to 1 / 7.3, but the winning probability of replay in the part lottery tables 62F to 62H is 1 / 1.2. Is set to

Here, the payout rate will be described.
The payout rate indicates the expected value of the payout number with respect to the number of inserted medals (expected value of payout number / insertion number). For example, each game, 3 medals are inserted and played, and a small role with a payout of 4 medals is won with a probability of 1/2 and won (the winning rate at the time of winning is 100%) Assume that
At this time, the expected value of the number of medals paid out in one game is
4 (sheets) × 1/2 (winning probability) = 2 sheets.

Therefore, the payout rate is
2/3 ≒ 0.667
It becomes.
When the payout rate exceeds 1, the game state is such that the number of medals gradually increases as the game progresses. When the payout rate is less than 1, the number of medals gradually decreases as the game progresses. It becomes a gaming state.

In this embodiment, during the normal game (including both inside and outside), the payout rate is set to be less than 1.
For example, when a game is played with three medals inserted, the winning probability of each combination is set as follows.
Small part 1 (four): 1/64
Small part 2 (six pieces): 1/32
Small part 3 (10 sheets): 1/8
Replay (3 photos): 1 / 7.3
As for replays, it is assumed that there are three payouts when winning a prize.

At this time, the expected medal payout number is
4 x 1/64 + 6 x 1/32 + 10 x 1/8 + 3 x 1 / 7.3
≒ 1.91 (sheets)
It becomes.
Therefore, the payout rate is
1.91 / 3
≒ 0.637
It becomes.
Accordingly, a gaming state in which the number of medals gradually decreases as the game progresses is achieved.
Further, the description of the case where the number of inserted medals is 1 and 2 is omitted, but the payout rate is set to be less than 1 as in the case where the number of inserted medals is 3.

In addition, during the BB game and the RB game, the winning probability of the small role 3 is 1 / 1.1, so the expected value of the number of medals paid out in one game is
4 × 1/64 + 6 × 1/32 + 10 × 1 / 1.1
≒ 9.34 (sheets)
It becomes.
Therefore, the payout rate is
9.34 / 3
≒ 3.11
It becomes.
Therefore, a gaming state in which the number of medals increases as the game progresses is achieved.

  Furthermore, during MB games, there will be no lottery for roles other than replay, but as will be described later, small roles can be won except during replay wins, so Assuming that wins, the payout rate will exceed 1.

Furthermore, during RT games, the winning probability of replay is 1 / 1.2, so the expected value of the number of medals paid out in one game when the number of inserted medals is three is
4 × 1/64 + 6 × 1/32 + 10 × 1/8 + 3 × 1 / 1.2
= 4 (sheets)
It becomes.
Therefore, the payout rate is
4/3
≒ 1.33
It becomes.

  Therefore, the RT game is in a gaming state in which the number of medals gradually increases (the payout rate exceeds 1) as the game progresses. In addition, in RT games, by adjusting the winning probability of replay, in addition to the case where the payout rate exceeds 1, the game state in which the payout rate is set to 1 (the number of medals is also present depending on the progress of the game) It is also possible to set the game state to be maintained) or a game state in which the payout rate is less than 1 but the medal is hardly reduced by the progress of the game (for example, the play rate is 0.95).

Returning to FIG.
The winning combination control means 63 controls how long the winning combination is maintained when one of the winning combinations is won, and includes a winning flag 63a.
FIG. 5 is a diagram showing the winning flag 63a in the present embodiment. In FIG. 5, (a) shows the winning flag 63a when one medal is inserted. As shown in FIG. 5A, the winning flag 63a for all the combinations (the combination in which the winning area is provided in the combination lottery table 62A (non-inside)) is selected by the combination lottery means 61 when one piece is inserted. Is provided.

  When the start switch 41 is operated and the winning lottery means 61 performs lottery, if the winning combination is won, the winning flag 63a corresponding to the winning combination is turned on. FIG. 5A shows a state in which a small combination 1 is won in the game, and a flag corresponding to the small combination 1 is switched from OFF to ON. When the winning combination is a small role or replay, the winning flag 63a is returned from ON to OFF at the end of the game regardless of whether the winning small role or replay is won in the game. (See FIG. 5 (a)).

  On the other hand, when a special combination (BB1, MB1, or RB1) is won, in the game until the combination of symbols corresponding to the special combination stops on the active line (until the selected special combination wins) The special role is maintained (carried over after the next game). That is, the on state of the winning flag 63a corresponding to the winning special combination is maintained until the special winning combination wins.

  For example, as shown in FIG. 5B, if BB1 is won in the game, but the combination of symbols corresponding to BB1 does not stop on the active line in the game, BB1 will be won even after the next game. Maintained. Then, the winning is maintained until the symbol combination corresponding to the winning BB1 stops on the active line. When the symbol combination corresponding to the winning BB1 stops on the active line, the winning flag 63a corresponding to BB1 is returned from ON to OFF.

  When a winning combination or replay is won while the winning of BB1 is maintained, in the game, the winning flag 63a corresponding to the selected winning combination or replay is switched from OFF to ON. In the same manner as described above, regardless of whether the winning combination or replay won in the game is won, the winning flag 63a related to the winning combination or replay is returned from ON to OFF at the end of the game. However, the winning flag 63a related to BB1 is kept on.

  In addition, when the BB1 win is maintained and the game is played with the number of inserted medals as it is, the special role lottery is not performed as described above, so the MB1 or RB1 win flag 63a never turns on.

FIG. 5C shows the winning flag 63a when two medals are inserted. As shown in FIG. 5 (c), the winning flag 63a for all the combinations (the combination in which the winning area is provided in the combination lottery table 62B (non-inside)) is selected by the combination lottery means 61 when two pieces are inserted. Is provided.
Similarly, FIG. 5D is a diagram showing a winning flag 63a when three medals are inserted. As shown in FIG. 5D, the winning flag 63a for all the winning combinations (the winning portion provided in the winning lottery table 62C (non-inside)) that are selected by the winning lottery means 61 when three pieces are inserted. Is provided.

  Also, for example, when a game is played with one medal inserted number and BB1 is won, and then a game is played with two medal inserted number (with BB1 winning maintained), BB2, MB2, RB2 A lottery of roles including special roles will be held. The same applies when a game is played with three medal insertions. Then, after winning the MB2 when the number of inserted medals is 2, when playing the game with the number of inserted medals being 3, the BB3, MB3, RB3 (with the BB1 and MB2 won) A lottery of roles including special roles will be held.

  First, the reel control means 64 controls to start rotation of all (three) reels 31 when the start switch 41 is operated. Further, the reel control means 64, when the stop switch 42 is operated, the lottery result of the combination by the combination lottery means 61 (ON / OFF state of the winning flag 63a) 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 a stop position determination table 65 described later, and the motor 32 is driven to control the reel 31 at the determined position. It is controlled to stop.

  For example, the reel control means 64 controls to stop the reel 31 so that the combination of symbols corresponding to the winning combination is 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 a combination of symbols corresponding to a combination other than the combination 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 movements of the symbol) from the moment when the stop switch 42 is operated until the reel 31 actually stops. In the present embodiment, except for the left reel 31 when the winning combination is not won in the MB game, the number is set within 5 symbols from the symbol at the moment when the stop switch 42 is operated. In other words, it means within the range of the stop control time of the reel 31, that is, the time from the moment when the stop switch 42 is operated until the reel 31 actually stops. In this embodiment, the moment when the stop switch 42 is operated. Within 190 ms.

  Thus, any of the symbols up to the number of symbols (5 symbols) within the range of 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. When the stop switch 42 is operated, the symbol is controlled to stop at the active line.

  In other words, 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, when the symbol related to the winning winning combination does not stop on the effective line, when the reel 31 stops, By controlling the rotational movement of the reel 31 within the “range of control”, the symbol related to the winning combination is controlled to stop as much as possible on the effective line.

  On the contrary, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated when the winning combination is not won, the combination of symbols corresponding to the winning combination is stopped on the effective line. When the reel 31 is stopped, the reel 31 is controlled to rotate and move within the “reel 31 stop control range” so that the symbol combination corresponding to the winning combination is not stopped on the active line.

  Further, “within the range of stop control of the reel 31” in the left reel 31 when the winning combination is not won in the MB game means the number of moving symbols from the moment when the stop switch 42 is operated until the reel 31 actually stops. Is within 2 symbols, in other words, the time from when the stop switch 42 is operated until the reel 31 actually stops is set within 75 ms.

The stop position determination table 65 is based on the lottery result of the combination by the combination lottery means 61 (ON / OFF of the winning flag 63a) and the position of the reel 31 at the moment when the stop switch 42 is operated. Is defined.
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 in the game before the game and the game is not won. The combination of symbols corresponding to (for example, in the case of BB1, "Red 7"-"Red 7"-"Red 7") is stopped on the active line, and the symbol combinations corresponding to roles other than BB are enabled. The combination of symbols when the reel 31 is stopped is determined so that the line does not stop.
Since BB has three types BB1 to BB3 as described above, a BB1 table, a BB2 table, and a BB3 table are provided.

Also, the MB table is the same as the BB table, and corresponds to a table in which “BB” in the BB table is replaced with “MB”. The MB table includes an MB1 table, an MB2 table, and an MB3 table.
Furthermore, the RB table is the same as the BB table, and corresponds to a table in which “BB” in the BB table is replaced with “RB”. The RB table includes an RB1 table, an RB2 table, and an RB3 table.

In addition, when the number of inserted medals is 1, either the BB1 table, the MB1 table, or the RB1 table may be used, but other special role tables (for example, the BB2 table) may be used. Absent.
Similarly, when the number of inserted medals is 2, either the BB2 table, the MB2 table, or the RB2 table may be used, but other special role tables (for example, the MB3 table) are used. There is no.
Similarly, when the number of inserted medals is 3, any of the BB3 table, the MB3 table, and the RB3 table may be used, but other special role tables (for example, the RB1 table) are used. There is nothing.

The small role 1 table is used on condition that the small role 1 is won in the game, and within the range of the stop control of the reel 31, the combination of symbols corresponding to the small role 1 is stopped on the effective line, The combination of symbols when the reel 31 is stopped is determined so that combinations of symbols corresponding to the combinations other than the small combination 1 are not stopped on the effective line.
The small role 2 table, the small role 3 table, and the replay table are respectively the same as the above small role 1 table, and “small role 1” in the small role 1 table is changed to “small role 2” and “small role 3”, respectively. "And" Replay ". When a replay is won during the MB game, a replay table is used.

Furthermore, the MB gaming table is used in a game when a winning combination is not won (other than during a replay winning) during an MB game, and a combination of symbols corresponding to a small role depending on the operation of the stop switch 42 by the player. Is a combination of symbols when the reel 31 is stopped so that it can be stopped on the active line. In other words, when the MB gaming table is used, the player can win a small role if the combination of symbols corresponding to any of the small roles can be stopped on the active line. Become.
When the replay is won during the MB game, the above-mentioned replay table is used.

  In addition, the non-winning table is a game in a non-winning state that does not carry over the winning of a special role in the number of medals inserted in the game (except for a case in which a role is not won in an MB game), or in a BB game A combination of symbols used when the reel 31 is stopped is determined so that a combination of symbols corresponding to any combination is not stopped on the active line, and is used in a game when the game is not won.

In addition, when a small role or replay is won during a game in which a special role has been won, a special role priority special role / small role table or a replay priority special role / replay table is used.
The special role priority special role / small role table is used when a small role is won during a game carrying over the special role election. First, the combination of symbols corresponding to the special role is stopped on the active line. If the combination of symbols corresponding to the special combination cannot be stopped on the effective line, the stop position determination table for stopping the combination of symbols corresponding to the small combination won in the game on the effective line is given next. 65.

  Further, when the combination of symbols corresponding to the small combination cannot be stopped on the effective line, the combination of symbols when the reel 31 is stopped so that the combination of symbols corresponding to any combination does not stop on the effective line. Is defined. The special role priority special role / small role table includes a BB1 priority BB1 / small role 1 table, a BB1 priority BB1 / small role 2 table,..., An RB3 priority RB3 / small role 3 table.

  The special role priority special role / small role table is used only when a small role is won in a state where the special role is maintained in the number of medals inserted in the game. For example, if you play a game with 1 medal inserted and win BB1, then you play a game with 1 medal inserted and win a small role, special role priority special role / small role A table is used.

  On the other hand, even if the special combination win is maintained with the number of medals other than the number of medals inserted in the game, the special combination win is not maintained with the number of medals inserted in the game. Even if a small role is won, the special role priority special role / pocket table is not used. For example, after playing a game with one medal inserted, winning BB1, and then playing a game with two medal inserted, the winning combination for special role is not maintained with two In such a case, a small role table described later (for example, when the small role 1 is won, the small role 1 table) is used.

In addition, the replay priority special role / replay table is used when a replay is won during a game carrying over the special role win. First, the combination of symbols corresponding to the replay won in the game is stopped on the active line. If the combination of symbols corresponding to replay cannot be stopped on the active line, then the stop position where the combination of symbols corresponding to the special role carrying over winning is stopped on the active line It is a decision table 65. Further, when the combination of symbols corresponding to the special combination cannot be stopped on the effective line, the combination of symbols when the reel 31 is stopped is set so that the combination of symbols corresponding to any combination does not stop on the effective line. Is defined.
The replay priority special combination / replay table includes a replay priority BB1 / replay table, a replay priority BB2 / replay table,..., A replay priority RB3 / replay table.

  In addition, the replay priority special role / replay table is the same as the special role priority special role / small role table described above, when the replay is won in a state where the winning of special role is maintained for the number of medals inserted in the game. Used only in Therefore, even if the winning of the special combination with the number of medals other than the number of medals inserted in the game is maintained, if the special combination is not maintained with the number of medals inserted in the game, Even if the replay is won, the replay priority special combination / replay table is not used, and the above-described replay table is used.

  Using the stop position determination table 65 described above, the reel control means 64 responds to the combination within the range of the stop control of the reel 31 when stopping the combination of symbols corresponding to any combination on the effective line. Control is performed so that the symbols constituting the combination of symbols to be stopped are stopped on the active line.

  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.

  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. 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.

The special game control means 68 starts the special game (BB game, MB game or RB game) (transition from normal game to BB game, MB game or RB game), during BB game, during MB game or during RB game. It controls the progress of the game and the end of the BB game, MB game or RB game.
First, during a normal game, when the symbol combination corresponding to BB (any one of BB1 to BB3) stops on the active line, BB is won and the special game control means 68 starts the BB game from the next game. Control to do.
In the BB game, the lottery of the combination is performed using the above-described combination lottery table 62D. As a result, a gaming state in which the small combination 3 is won with high probability is obtained.

In the present embodiment, the BB game end condition is set such that the number of medals paid out during the BB game is 345 or more.
Accordingly, the special game control means 68 counts the number of medals paid out during the BB game, and keeps updating the number of medals paid out for each game.
When the special game control means 68 determines that the counted number of payouts is 345 or more, the special game control means 68 determines that the BB game end condition is satisfied.

In addition, during a normal game, when a combination of symbols corresponding to MB (any of MB1 to MB3) stops on the active line, MB is won and the special game control means 68 starts the MB game from the next game. Control to do.
In the MB game, the lottery of the combination is performed using the above-described combination lottery table 62E. Since the MB gaming table is used when the winning combination is not won, it is possible to win the small winning combination except when the replay is won.

In the present embodiment, as the MB game end condition, the number of medals paid out during the MB game is set to be 253 or more.
Therefore, the special game control means 68 keeps counting the number of medals paid out during the MB game and updates the number of medals paid out for each game.
When the special game control means 68 determines that the counted number of payouts is 253 or more, it determines that the MB game end condition is satisfied.

Furthermore, when the combination of symbols corresponding to RB (any one of RB1 to RB3) stops on the active line, the special game control means 68 shifts from the normal game to the RB game. Also in the RB game, a game is played using the winning lottery table 62D, and a gaming state in which the small role 3 is won with high probability is obtained.
In the present embodiment, the RB game end condition is set such that the number of winning a winning combination reaches 8 times or the number of games reaches 12 times.

Therefore, in this embodiment, the special game control means 68 counts the number of winnings and the number of games for the winning combination in the RB game, and continuously updates the number of winnings and the number of games for each game. When it is determined that the number of games has been reached or the number of games has reached 12, the CPU determines that the RB game end condition is satisfied.
For example, in an RB game, assuming that every game (all 8 games) and small role 3 are won and won, the payout number of medals during the RB game is 80.

  In the present embodiment, the winning of a plurality of special roles can be stocked. However, for example, when two special roles BB1 and RB3 are stocked, it is arbitrary which one of the special roles is awarded first, and the player You can decide freely. Then, immediately after the end of either one of the special games, that is, the next game after the end of the special game, the remaining special roles can be won and the game can be shifted to the special game.

The RT game control means 69 determines whether or not to set the game after the end of the special game as an RT game, and when setting it as an RT game, determines the number of games.
First, the RT game control means 69 determines whether or not to execute the RT game according to the stock number of special roles. For example, after playing a game with 3 medals inserted and winning BB3, BB3 was won with 1 or 2 medals inserted without playing (3 medals inserted) In this case, the maximum stock number of the winning special combination is one, and in this case, the RT game control means 69 determines not to execute the RT game.

  Also, for example, a game with one medal inserted number is played and RB1 is won, then a game is played with two medal inserted number and a game is won with MB2, and then the game is played with three medal inserted number. If the RB1 or MB2 is won and the RB game or the MB game is entered without performing the medals (the number of inserted medals is 1 or 2), the maximum stock number is 2, and in this case, RT game control means 69 decides to execute the RT game.

  Furthermore, for example, the number of inserted medals is 2 and a game is played to win BB2, then the number of inserted medals is 1 and the game is played to win MB1, and then the number of inserted medals is set to 3. When the game is won and BB3 is won, the maximum stock number is 3, and in this case, the RT game control means 69 decides to execute the RT game.

Also, the RT game control means 69 performs control so that the RT game is executed after the special games related to all the special roles that have been stocked.
In the above example, when RB1 and MB2 (two) are stocked, after both the RB game transitioned by the winning of RB1 and the MB game following by the winning of MB2 are finished (the last game of the special game) From the next game, the RT game is executed.
Similarly, in the above example, when BB2, MB1, and BB3 (three) are stocked, the BB game that shifts by winning BB2, the MB game that shifts by winning MB1, and the BB3 winning shift After all the BB games are finished, the RT game is executed.

In the present embodiment, the RT game control means 69 sets 100 games as the number of RT games when two special roles are stocked. On the other hand, when three (all) special roles are stocked, the RT game control means 69 sets 300 games as the RT game number of times.
Not limited to this, the RT game control means 69 may determine the number of RT games by lottery. In addition, when the number of stocks is three, it is only necessary to make it easier to select a longer number of games than when the number of stocks is two.

When executing the RT game, the RT game control means 69 performs the lottery using the above-described combination lottery table 62F, 62G, or 62H in accordance with the number of inserted medals.
Then, the RT game control means 69 controls to end the RT game when the RT game reaches the predetermined number of games (100 games or 300 games). Thereby, the normal game is executed from the next game.

Therefore, in the present embodiment, the RT game is controlled so as not to end even if a special role is won on the way unless the number of RT games reaches the specified number. For example, when 100 games are set as RT games, first, three medals are inserted and played, then BB3 is won at the 70th game, and then two medals are inserted and played. In such a case, 30 games are set as RT games in the game played by inserting two medals.
However, during the RT game, for example, when 3 medals are inserted to play a game, and BB3 is won, if the 3 medals are subsequently inserted and the game continues, the normal game is not an RT game. (Inside).

  In addition, when the first special combination is won during execution of the RT game, the RT game control means 69 can also control to end the RT game. Therefore, when a special game is won during RT game and the game is played without changing the number of inserted medals after the next game, the normal game (inside) role lottery table 62 is used. Also, when a game is played after changing the number of medals after winning the special combination, the combination lottery table 62 for the normal game (non-inside) is also used.

In the present embodiment, the RT game may be executed even when the number of stocks of special roles is one. In this case, control is performed so that the RT game having a smaller number of games is executed than when the number of stocks of special roles is two or three.
Alternatively, it is controlled so that the RT game is executed only when the number of stocks of special roles is three, and it is controlled so that the RT game is not executed when the number of stocks of special roles is one or two. good.

The effect control means 70 controls the output of the effects from the lamp 21, the speaker 22, and the image display device 23 described above.
For each game, the effect control means 70 selects an effect pattern (which determines what effect should be output and at what timing) based on the lottery result of the role by the role 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.
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.

  In the slot machine 10 described above, the player first plays a game by selecting any one of 1 to 3 medal insertions. Here, it is assumed that the number of inserted sheets is first selected. Next, suppose that BB1 is won in a game with one inserted game. When the symbol combination corresponding to BB1 is not stopped on the active line in the game won for BB1, the winning flag 63a of BB1 is kept on. Then, in the next game, one medal can be inserted and the combination of symbols corresponding to BB1 can be stopped on the active line.

  On the other hand, after the next game, the number of medals inserted can be two or three. When the game is played with two or three medals inserted, the winning combination of BB1 remains carried over and the combination of symbols corresponding to BB1 does not stop at the active line. This is because the BB1 table (or the BB1 priority BB1 / small role table and replay priority BB1 / replay table capable of stopping BB1) is not used in a game in which the number of inserted medals is two or three.

  Further, when a game is played with two or three medals inserted in a state where the winning of BB1 is carried over, a special combination lottery corresponding to each medal inserted number is performed. For example, when a game is played with two medals inserted after winning BB1, a lottery of BB2, MB2, and RB2 is performed. If the number of inserted medals is 1, the player has already won BB1 and is in the inside of BB1, but when the number of inserted medals is switched to 2, it is not in the inside of the special role.

  Here, as a result of playing the game with the number of inserted medals being two, it is assumed that MB2 is won. When the symbol combination corresponding to MB2 is not stopped on the active line in the game won for MB2, the winning flag 63a of MB2 is kept on. Then, in the next game, two medals can be inserted and the symbol combination corresponding to MB2 can be stopped on the active line. Alternatively, it is possible to set the number of inserted medals to 1 and stop the combination of symbols corresponding to the previously won BB1 on the active line.

On the other hand, after the next game, it is also possible to play a game with three medal insertions. When a game is played with the number of inserted medals being 3, the winning combination of BB1 and MB2 remains carried over and the combination of symbols corresponding to BB1 and MB2 does not stop on the active line. This is because a BB1 table that can win BB1, an MB2 table that can win MB2, or the like is not used in a game with three medals inserted.

Here, it is assumed that RB3 is won as a result of playing the game with 3 medal insertions. As a result, all the medals inserted are inside. Therefore, after that, no matter how many medals are inserted, the special combination lottery is not performed.
Then, the player can select a special combination that he / she wants to win (a special game to be transferred) by selecting the number of medals inserted.
For example, first, if a game is played with the number of inserted medals being 2, the inside of MB2 is reached, so that MB2 can be won and the game can be shifted to MB game.

Even after the end of the MB game, by selecting the number of medals inserted, it is possible to select the special combination (special game to be transferred) to be awarded.
For example, if a game is played with the number of inserted medals being 1, the inside of BB1 is entered, so that BB1 can be won and a transition to BB game can be made.
Even after the end of the BB game, by selecting the number of inserted medals, it becomes a game inside the RB3, so that it is possible to win the RB3 and shift to the RB game.

  As described above, if a special combination is won for each number of medals, it is possible to shift to special games by winning the selected special combination each time. After winning the special role, it will be possible to digest the special game at once. Thereby, the player can rapidly increase the number of medals obtained and can increase the instantaneous power of appearing balls.

  In addition, if the player increases the number of stocks and wins a special role, he can execute a RT game with a longer number of games after the end of the special game (which is advantageous for the player) It is thought that efforts will be made to increase the number of stocks. Therefore, there are few cases where a special role is won when the number of stocks is one, and in many cases, when three special roles are stocked, a special game is executed more at once, There are many opportunities to increase the instantaneous power of the ball.

(Modification 1 of the first embodiment)
Modification 1 of the first embodiment is different from the first embodiment in determining how long an RT game will be executed. The rest is the same as in the first embodiment.
In the first modification of the first embodiment, the RT game control means 69 performs control so that the RT game is executed after the special game ends, regardless of the number of stocks. When the maximum stock number is one, the RT game control means 69 performs a lottery with a 1/10 winning probability during the RT game, and when the lottery is won, The game is controlled to end, and the normal game is executed from the next game.

In addition, when the maximum stock number is two, the RT game control means 69 performs a lottery with a winning probability of 1/50 every time during the RT game, and when the lottery is won, the RT game is terminated. Control to do. Similarly, when the maximum stock number is 3, the RT game control means 69 performs a lottery with a winning probability of 1/200 during the RT game, and when the lottery is won, the RT game is terminated. Control to do.
With this setting, the larger the maximum stock number, the greater the expected value of the number of RT games played after the end of the special game.

(Modification 2 of the first embodiment)
The modification 2 of 1st Embodiment differs in timing which performs RT game from 1st Embodiment. The rest is the same as in the first embodiment.
In the second modification of the first embodiment, when the number of stocks of special roles becomes two, the RT game control means 69 determines that RT games in games with the number of medals inserted where the special role is not stocked. Control to execute. For example, when the number of inserted medals is 1, the player wins BB1, and then plays with the number of inserted medals set to 2, and when the player wins the game with RB2, the game is played with the number of inserted medals set to 3. And this game is set to RT game.

Also, as in the above example, when the number of inserted medals is 1 and 2 and special roles are stocked, and when the game is played with the number of inserted medals next three, the special combination is won with the number of medals. The RT game is executed until (until one of BB3, MB3, or RB3 is won). As a result, when the number of stocks for winning the special role is two, the player can wait for the special role while increasing the number of medals owned for the third special role.
However, the present invention is not limited to this, and for a game with three inserted medals, an upper limit may be set for the number of RT games (for example, 200 games). Alternatively, as in Modification 1 of the first embodiment, a lottery may be performed to determine whether or not to end each game and the RT game, and the RT game may be continued until the lottery is won.

(Second Embodiment)
The second embodiment differs from the first embodiment in the combination that is randomly drawn during the normal game. In the second embodiment, the small combination 3 is not provided, but instead, a small combination 3A, a small combination 3B, and a small combination 3C are provided.
Further, the combination of symbols of the small role 3A, the small role 3B, and the small role 3C is set to “bell”-“bell”-“bell” and is common.
Furthermore, the winning areas of the small combination 3A, the small combination 3B, and the small combination 3C are set to 1/8, which is the same as the small combination 3 of the first embodiment. Therefore, the winning area of the entire small combination 3 is set to 3/8.

  In the second embodiment, the reel control unit 64 includes an operation order detection unit 64a. The operation order detecting means 64a detects whether the stop switch 42 operated first is any of left, middle or right when one of the small roles 3A to 3C is won.

The reel control means 64 uses the small role 3A table as the stop position determination table 65 when winning the small role 3A, and uses the small role 3B table when winning the small role 3B, and wins the small role 3C. When this happens, the reel 31 is controlled to stop using the small role 3C table.
Here, the small role 3A table is used on condition that the small role 3A is won in the game. When the stop switch 42 operated first is the left stop switch 42, the range of stop control of the reel 31 is used. The combination of symbols corresponding to the small role 3A is stopped on the active line, and the combination of symbols corresponding to roles other than the small role 3A is not stopped on the effective line. Alternatively, in the case of the right stop switch 42, the combination of symbols when the reel 31 is stopped is determined so that the symbol combination corresponding to any combination does not stop on the effective line.

  The small role 3B table is used on the condition that the small role 3B is won in the game. When the stop switch 42 operated first is the middle stop switch 42, the small role 3B table is within the range of the stop control of the reel 31. The combination of symbols corresponding to the small role 3B is stopped on the active line and the combination of symbols corresponding to the roles other than the small role 3B is not stopped on the effective line. In the case of the right stop switch 42, the combination of symbols when the reel 31 is stopped is determined so that the symbol combination corresponding to any combination does not stop on the effective line.

  Furthermore, the small role 3C table is used on the condition that the small role 3C is won in the game. When the stop switch 42 operated first is the right stop switch 42, the range of the stop control of the reel 31 is used. The combination of symbols corresponding to the small role 3C is stopped on the active line, and the combination of symbols corresponding to roles other than the small role 3C is not stopped on the effective line. Alternatively, in the case of the middle stop switch 42, the combination of symbols when the reel 31 is stopped is determined so that the symbol combination corresponding to any combination does not stop on the effective line.

As described above, when winning the small combination 3A, the small combination 3B, and the small combination 3C, if the stop switch 42 to be operated first is not correct, even if the winning combination is won, no prize is won.
In the second embodiment, “bell” symbols are arranged at intervals of 5 symbols or less (within the range of stop control of the reels 31) for all of the left, middle and right reels 31. As a result, when any of the small combinations 3A to 3C is won and the stop switch 42 to be operated first is correct, the selected small combinations 3A to 3C win a prize.

Therefore, when one of the small roles 3A to 3C is won, the player wins with a probability of 1/3 and does not win with the probability of 2/3. That is, normally, any one of the small roles 3A to 3C wins with a probability of 3/8, but since the winning rate is 1/3, the expected number of payouts is the same as in the first embodiment. .
On the other hand, if the stop switch 42 to be operated first can be known at the time of winning the small roles 3A to 3C, the winning rate will be 100%. Therefore, the expected number of payouts based on the small roles 3A to 3C is expected. The value is tripled.

Further, in the second embodiment, the effect control means 70 operates the stop switch 42 in order of winning a prize when any of the small roles 3A to 3C is won in the game after the end of the special game (firstly In addition to determining whether or not to notify the stop switch 42) to be operated, if notifying, the number of notifications is determined.
That is, in the first embodiment, the number of games of RT games is determined according to the number of stocks of special roles, but in the second embodiment, when the small roles 3A to 3C are first elected according to the number of stocks of special roles. A game (AT game) for notifying the stop switch 42 to be operated is executed.

And in this embodiment, the production | control control means 70 determines the frequency | count of alerting | reporting to 5 times when the maximum stock number of special roles is 1, and when the maximum stock number is 2, it determines the frequency | count of alerting | reporting. When the maximum stock number is 3, the number of notifications is determined to be 50 times. For example, when the number of notifications is determined to be five, notification is performed until any of the small combinations 3A to 3C wins five times. When any of the small roles 3A to 3C has been won six times or more, no notification is made.
However, the present invention is not limited to this, and the effect control means 70 may determine the number of notifications by lottery. In addition, when lottery is performed, the longer the number of notifications, the easier it is to select the number of notifications.

  Furthermore, instead of the number of notifications, the number of games (game period) for which notification is performed may be determined. For example, when the number of games to be notified is determined to be 200 games, the stop switch 42 to be operated first during any of the small roles 3A to 3C is won for 200 games after the end of the special game. Informed. And after the 201st game, even if any of the small roles 3A to 3C is won, no notification is made.

  Further, in the case of performing notification, the effect control means 70 displays an image of “left” on the image display device 23, for example, when winning the small role 3A. If the player first operates (turns on) the stop switch 42 in accordance with this instruction, the player can win the winning combination 3A. Similarly, when the small role 3B is won, an image of “middle” is displayed, and when the small role 3C is won, an image of “right” is displayed.

In addition, the payout rate in the second embodiment is as follows.
First, when winning the small roles 3A to 3C, when the stop switch 42 to be operated first is not known, the winning rate based on the small roles 3A to 3C is 1/3. The same as the first embodiment (0.637).
On the other hand, when notification is given at the time of winning the small combination 3A to 3C, the winning rate is 100%.
Therefore, when the number of inserted medals is 3, the expected value of the number of medals paid out in one game is
4 × 1/64 + 6 × 1/32 + 10 × 3/8 + 3 × 1 / 7.3
= 4.41 (sheets)
It becomes.
Therefore, the payout rate is
4.41 / 3
≒ 1.47
It becomes.
Therefore, AT games are in a gaming state in which the number of medals gradually increases as the game progresses.

(Modification 1 of 2nd Embodiment)
In the said 2nd Embodiment, it alert | reported to the normal game after completion | finish of a special game. On the other hand, in the first modification of the second embodiment, control is performed so that a predetermined number of games are notified in the game in the inside (game before winning the special role).
For example, when the special roles are stocked for all the number of inserted medals (when the number of stocks is 3), the notification shown in the second embodiment is issued in the game inside the first special role before winning. Do. The number of notifications can be set to a fixed value (for example, 30 times) or determined by lottery.
In this way, when the number of stocks of special roles becomes 3, the player can shift to a special game through an AT game (a game in which the number of medals owned increases).

(Modification 2 of the second embodiment)
In the second modification of the second embodiment, the small combination 3A to the small combination 3C are drawn in the BB game. In this embodiment, the BB game is controlled to end when the number of games reaches a specified number (for example, 30 games) regardless of the number of medals paid out (or acquired) during the BB game. .
For example, when all three special roles are stocked and at least one of them is a BB, when the BB game is won by winning the BB, the first time when the small roles 3A to 3C are elected The stop switch 42 to be operated is notified.

  As a result, when the number of stocks of special roles is 2 or less and the game shifts to BB game, the stop switch 42 to be operated first is not notified when the small roles 3A to 3C are selected. 3A to 3C cannot be reliably won. On the other hand, when all three special roles are stocked and the game shifts to BB game, the stop switch 42 to be operated first is notified when the small roles 3A to 3C are selected. 3A to 3C can be surely won.

  Therefore, the number of medals that can be earned during a BB game when the number of stocks of special roles is 2 or less and the game shifts to BB games, and when the number of stocks of special roles reaches 3 and then shifts to BB games. Can make a difference.

  In addition, when winning of two or more special roles (at least one is BB) is stocked, the stop switch 42 to be operated first is notified at the time of winning the small roles 3A to 3C during the BB game, It is also possible not to notify when the winning of one special role is stocked.

(Modification 3 of 2nd Embodiment)
In the modification 3 of 2nd Embodiment, according to the kind and number of the special role which stocked, alerting | reporting content differs. For example, when one winning combination is stocked, the stop switch 42 to be operated first is not notified when the small combination 3A to the small combination 3C is won. Alternatively, only the fact that the small combination 3A to the small combination 3C are won is notified.

When two special combinations are stocked, the stop switch 42 to be operated first is notified with two choices when the small combinations 3A to 3C are selected. For example, when the small role 3A is won, it is notified that either one is correct, such as “left or right”. Furthermore, when three special combinations are stocked, the stop switch 42 to be operated first is notified (by one choice) when the small combination 3A to the small combination 3C are selected. For example, when the small role 3B is elected, “medium” is notified.
As described above, when the small combination 3A to the small combination 3C is won, not only the stop switch 42 to be operated first but also the notification can be notified with two choices.

(Modification 4 of the second embodiment)
Modification 4 of the second embodiment is a combination of the first embodiment and the second embodiment (ART game). That is, a game in which a small role 3A to a small role 3C are drawn and the winning probability of the replay is increased in the same manner as the RT game of the first embodiment is given to the player according to the number and type of special roles stocked. It is to provide.

In an ART game, when the winning probability of replay is 1 / 1.2, and the winning probability of any of the small roles 3A to 3C is 3/8, in one game when the number of inserted medals is three The expected value of the number of medals to be paid out is
4 × 1/64 + 6 × 1/32 + 10 × 3/8 + 3 × 1 / 1.2
= 6.5 (sheets)
It becomes.
Therefore, the payout rate is
6.5 / 3
≒ 2.17
It becomes.
Therefore, it is possible to increase the payout rate more than RT games and AT games.

(Modification 5 of the second embodiment)
In the fifth modification of the second embodiment, the three small combinations 3 are not the three small combinations 3A to 3C, but six small combinations 3A to 3F. The winning area of the small combination 3 is divided into six equal parts, and the winning areas of the small combination 3A, the small combination 3B,. The operation order of the stop switch 42 corresponding to the small role 3A (for winning the small role 3A) is in the order of middle left and right, the operation order of the small role 3B is in the order of left and right, and the small role 3C. The operation order of the small role 3D is the order of middle right and left, the operation order of the small role 3E is right and left middle order, and the operation order of the small role 3F is right middle left In the order.

Specifically, for example, when winning a small role 3A, if the stop switch 42 is operated in the order of left middle right, the winning small role 3A wins, but when it is operated in five different operation orders Does not win the small role 3A. The same applies to the other small roles 3B and the like.
Further, the effect control means 70 notifies “middle left and right” when the small role 3C is won, for example.
If it carries out as mentioned above, when alerting | reporting will be performed, the winning rate of small part 3A-small part 3F will be 6 times compared with the time when not alert | reporting. Therefore, it is possible to provide a large difference in the payout rate when notification is performed and when notification is not performed.

(Third embodiment)
In the third embodiment, control is performed so that a sub game is played during a BB game.
Here, the sub game is output by an effect output device (the lamp 21, the speaker 22, and the image display device 23), and a game is played using the operation switches, particularly the three stop switches 42 in the present embodiment. Is what you do. The sub game is a game of the slot machine 10 itself (a series of games in which the reel 31 is rotated and a winning lottery is performed, and then the reel 31 is stopped and medals are paid out according to the combination of symbols at the time of the stop. ), And the game result in the sub game does not affect the number of medals paid out during the BB game.
In this embodiment, the number of RT games after the end of the BB game is determined according to the score in the sub game.

  First, when the sub game shifts to the BB game, a sub game of one game is played continuously for ten games (10 times). Here, for each game, when the start switch 41 is operated for each game, the image display device 23 displays images arranged in the horizontal direction with the three playing cards turned upside down. Then, by operating any one of the left, middle, or right stop switches 42, the player is made to select a playing card to be opened. For example, the player operates the left stop switch 42 to open the left playing card. When the player selects a playing card, an image is displayed with the playing card on the front side.

Here, out of the three playing cards distributed to the player, one of the symbols is a joker. Each time a joker's playing card is assigned, one point is added as a score. Therefore, in the sub game, 0 points (lowest score) to 10 points (full score, highest score) are awarded.
Note that which of the left, middle and right playing cards is set as the joker is determined by lottery by software random numbers, etc. by each game and effect control means 70.

And in the normal game after the end of the BB game, the small combination 3A to the small combination 3C shown in the second embodiment is drawn. And the frequency | count of alerting | reporting is determined according to the score in a subgame. For example, when the score in the sub game is 3 or less, the number of notifications is 5, and when the score is 4 or more and 6 or less, the number of notifications is 10; when the score is 7 or more and 9 or less, the number of notifications Is 30 times and 10 points, the number of notifications is determined to be 100 times.
In this way, the effect control means 70 notifies the stop switch 42 to be operated first when the small combination 3A to the small combination 3C is won according to the score in the sub game.

In addition, the above is a case where the maximum stock number of the special combination before shifting to the BB game is one or two.
On the other hand, when the maximum stock number of special roles before the transition to the BB game is 3, the effect control means 70 displays two cards in parallel and displays one card as a player. To select. Here, the player operates the left stop switch 42 when selecting the left playing card, and operates the right stop switch 42 when selecting the right playing card.

In this way, when the maximum stock number of special roles before transitioning to BB game is 1 or 2, it will be 3 choices and the correct answer rate will be 33.3%, but in BB game If the maximum stock number of special roles before the transition is 3, the choice will be 2 choices and the correct answer rate will be 50%. As a result, the latter is more likely to have a higher total score in the subgame.
Therefore, it is advantageous for the player to shift to the BB game after setting the number of stocks to three.
Note that the number of notifications may be determined in the same manner as described in the second embodiment, instead of determining the number of notifications according to the score in the sub game.

(Fourth embodiment)
Similar to the first embodiment, the fourth embodiment controls to execute the RT game after the special game is finished. The number of RT games is determined in accordance with the order in which special roles are stocked.
In the fourth embodiment, when the BB is stocked before the RB is stocked, the RT game is executed in the normal game after all the special games are finished. Therefore, for example, when the stock is made in the order of MB1 → RB3 → BB2, the RT game is not executed. On the other hand, for example, when stock is made in the order of BB3 → MB1 → RB2, RT game is executed. In addition, the number of RT games is set to 200 games.

  Also, for example, when the number of inserted medals is 1, RB is set to be most easily won, and when the number of inserted medals is 3, BB is set to be most easily won. First, when the game is played with the number of inserted medals set to 3, and BB is won, the game can be given such that the number of inserted medals is set to 1 and the RB is won.

In the fourth embodiment, the AT game as in the second embodiment may be executed or the ART game may be executed after the special game is finished, according to the order in which the special roles are stocked.
Further, according to the order in which the special roles are stocked, an AT game or an ART game may be executed as an internal game before shifting to the special game, or an AT game may be executed during the special game.

(Modification 1 of 4th Embodiment)
In the first modification of the fourth embodiment, when at least one BB and RB are stocked, control is performed so that the RT game is executed in the normal game after the completion of all the special games. On the other hand, when at least one BB and RB are not stocked, the RT game is controlled not to be executed in the normal game after all the special games are finished. For example, when three BB1, MB2, and RB3 are stocked, the RT game is executed after the end of the special game, but when three BB1, MB2, and MB3 are stocked, (RB is not stocked) So) RT game is not executed after the end of the special game.

Furthermore, in the first modification of the fourth embodiment, when BB is stocked before RB is stocked, RT games of 100 games are executed. For example, the case where it stocks in order of MB2->BB3-> RB1 is mentioned.
On the other hand, when RB is stocked before BB is stocked, RT games of 300 games are executed. For example, the case where it stocks in order of RB2->MB3-> BB1 is mentioned.

Note that in the first modification of the fourth embodiment as well, the AT game as in the second embodiment may be executed instead of the RT game, or the ART game may be executed.
Further, an AT game or an ART game may be executed as an internal game before the transition to the special game, or an AT game may be executed during the special game.

(Fifth embodiment)
As in the first embodiment, the fifth embodiment controls to execute an RT game after the end of the special game. The number of RT games is determined according to the type of special role stocked.
In the fifth embodiment, when two or more BBs are stocked, the number of RT games after the end of the special game is determined to be 200. In other cases, the number of RT games after the end of the special game is determined to be 100 times. For example, when RB1 is first stocked, then BB3 is stocked, and then BB2 is stocked, two or more BBs are stocked, so RT games after the end of (all) special games The number of games is determined to be 200. On the other hand, for example, when RB2 is stocked first, then BB1 is stocked, and then MB3 is stocked, the number of stocks of BB is 1, so after the end of (all) special games The number of RT games is determined to be 100.

In determining the number of games of RT games, the number of games may be determined as in Modification 1 of the first embodiment.
In the fifth embodiment, an AT game as in the second embodiment may be executed instead of an RT game, or an ART game may be executed.
Furthermore, an AT game or an ART game may be executed as an internal game before shifting to a special game, or an AT game may be executed during a special game.

(Sixth embodiment)
In the sixth embodiment, control is performed such that the greater the number of RB stocks, the greater the number of RT games executed after the end of the special game.
As described above, there are three types of special games, BB game, MB game, and RB game, which are set so that the number of medals paid out during the RB game is the smallest. Therefore, the more RB games are executed, the fewer the number of medals that the player can acquire. In order to remedy this, in the sixth embodiment, the larger the number of RB games stock, the longer the number of RT games played after the end of the special game.

  For example, when the number of RB stocks is 0 or 1, the number of RT games after the end of the special game is set to 30. When the number of RB stock is two, the number of RT games after the end of the special game is set to 100. Furthermore, when the number of RB stock is 3, the number of RT games after the end of the special game is set to 200.

In determining the number of games of RT games, the number of games may be determined as in Modification 1 of the first embodiment.
Further, according to the number of RB stocks, an AT game as in the second embodiment may be executed instead of an RT game, or an ART game may be executed.
Furthermore, an AT game or an ART game may be executed as an internal game before shifting to a special game, or an AT game may be executed during a special game.

(Seventh embodiment)
Subsequently, a seventh embodiment will be described.
FIG. 6 is a diagram showing a combination lottery table 62B ′ (non-inside) when the number of inserted medals is two in the seventh embodiment. In the seventh embodiment, RB2 and RB3 are provided as RBs to be selected when the number of inserted medals is two. That is, RB3 is selected by lottery with two and three medal insertions.
FIG. 7 is a diagram showing the winning flag 63a when the number of medals inserted is two. As described above, when the number of inserted medals is 2, lottery is performed for both RB2 and RB3, so that a winning flag 63a for both RB2 and RB3 is provided.

In the seventh embodiment, first, assume that two medals are inserted and a game is played, and BB2, MB2, or RB2 is won. Thereafter, when three medals are inserted to play a game, all of BB3, MB3, and RB3 are drawn as special roles.
On the other hand, it is assumed that RB3 is won as a result of playing a game by inserting two medals. After that, when a game is played with three medals inserted, the special combination is not drawn. This is because the RB 3 that is selected by lottery when three medals are inserted is already selected when the number of inserted medals is two, so when the number of inserted medals is three, it is already inside. In other words, as a result of playing a game by inserting two medals, when winning RB3, the winning flag 63a corresponding to RB3 when three medals are inserted is also turned on.

FIG. 8 is a diagram showing a winning flag 63a indicating the above flow.
In FIG. 8, first, when the number of medals inserted is two and RB3 is won, the RB3 flag is turned on. Thereafter, when the number of inserted medals is 3, the winning flag 63a of RB3 is on.

In this way, when the same special combination is provided between different medal insertion numbers, when the special combination is won with one medal insertion number, even when the other medal insertion number is selected The special role is already elected and is inside.
In order to win the special combination, either one medal insertion number or the other medal insertion number may be used. Regardless of the number of medals inserted, the special combination can be won.

  When the special combination is won, the winning flag 63a corresponding to the special combination is turned on in both the winning flag 63a with one medal inserted number and the winning flag 63a with another medal inserted number. To switch off.

  The same applies to the reverse case. Suppose that three medals are inserted to play a game, and RB3 is won. After that, when a game is played with two medals inserted, the special combination is not drawn. The RB 3 that is selected when the number of inserted medals is 2 is already selected when the number of inserted medals is 3. Therefore, when the number of inserted medals is 2, the RB3 is already processed as inside.

(Eighth embodiment)
In the first embodiment, after a special combination is won, if a game is played with a different number of medals inserted at the time of winning, the stop position determination table 65 in which the selected special combination does not win is used. On the other hand, if a game is played with the number of medals inserted after winning the special combination, the stop position determination table 65 for winning the selected special combination is used.
For this reason, if a player who does not wish to receive the stock for the special role wins the special role and then plays the game while maintaining the number of medals inserted, even if the number of stocks for the special role is one, A special role can be won and a special game can be entered.

On the other hand, in the eighth embodiment, if the number of medals inserted is 1 to 3 and the special combination is not won (if the number of stocks of the special combination does not become three), the stop position determination for winning the special combination is determined. The table 65 is controlled so as not to be selected.
Therefore, the player cannot move to the special game until the number of stocks of the special role becomes three.
If the number of stocks of special roles is two, it is possible to select the stop position determination table 65 for winning special roles.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications as described below are possible.
(1) For example, in this embodiment, a medal is used as a game medium. However, the present invention can be applied to a slot machine using a game medium other than a medal, such as a slot machine (parrot) using a game ball. it can.

  (2) In the present embodiment, the number of medals inserted is set to be one, two, or three, but the game can be played with two types of medals inserted (specifically, one and one (2 cards, 1 card and 3 cards, or 2 cards and 3 cards, etc.) It is possible to play with 4 or more types of medal insertions. In this case, if it is possible to play with two types of tokens inserted, it is possible to carry over the winning of up to two special roles. In addition, when it is possible to play with N (N ≧ 4) types of medals inserted, it is possible to carry over the winning of up to N special roles.

  (3) In the present embodiment, the player can select the number of game media inserted. However, the present invention is not limited to this, and it may be set in advance on the slot machine 10 side. For example, at the beginning (when no special role wins have been carried over), the game is played with the number of inserted medals set to 1 (the game cannot be played with 2 or 3 inserted medals). Like that. After winning one of the special roles, from the next game, the number of inserted medals is set to 2 and the game is played (the game cannot be played with 1 or 3 inserted medals). .

  Then, after winning one of the special roles, from the next game, the number of medals inserted is set to 3 and the game is played (the game cannot be played with 1 or 2 inserted medals). . Then, after winning one of the special roles, the player selects from 1 to 3 medal insertion numbers (or with a predetermined medal insertion number) (the winning combination is carried forward). It is also possible to make it possible to win special roles sequentially.

(4) In the second embodiment and the like, as an AT game, a game for notifying the operation order of the stop switch 42 is given as an example. However, the present invention is not limited to this, for example, Patent No. 3509699 in which the present applicant is a patentee It may be the AT game disclosed in the above. That is, for example, the combination of symbols corresponding to the small role 3A is “red 7”-“bell”-“bell”, and the combination of symbols corresponding to the small role 3B is “blue 7”-“bell”-“bell”, The combination of symbols corresponding to the small role 3C is set to “BAR” − “Bell” − “Bell”. Then, “red 7”, “blue 7”, and “BAR” in the left reel 31 are arranged at an interval of 7 symbols (interval exceeding the range of stop control of the reel 31 (within 5 symbols)). In this way, for the left reel 31, only one of “red 7”, “blue 7”, and “BAR” can be stopped on the active line. In this case, in the AT game, when winning the small combination 3A to 3C, the symbols related to the left reel 31 of the selected small combination 3A to 3C are displayed on the image display device 23, for example. Thereby, in AT games, when winning the small role 3A to 3C, if the left reel 31 is pushed according to the notification, the selected small role 3A to 3C can always be won. On the other hand, in the non-AT game, when winning the small role 3A to the small role 3C, it is possible to win only by chance (with a probability of 1/3).
The above types of AT games can also be used in the present invention.

It is a block diagram which shows the outline of control of a slot machine. It is a figure which shows the combination of the kind of combination, the number of payout, etc., and a symbol.
