Description

The present invention relates to a slot machine that shifts to a gaming state that is more advantageous than the previous RT gaming state when a combination of symbols of special roles does not stop for a certain number of games in a plurality of RT gaming states . It is.

  In a conventional slot machine, there is known a slot machine that carries over the winning of a special role and releases the special role that has been carried over when a predetermined condition is satisfied (controlling so that a winning can be made) (for example, , See Patent Document 1).

  Also, if the release conditions for special roles that carry over the winnings are not met for a predetermined number of games, for example, 1500 games (when it is not possible to win a prize), the special features carried over as a ceiling function There is known a slot machine that emits the.

JP 2005-334522 A

However, in the above-described conventional technology, there is a tendency that it is not preferable that the special role cannot be won unless the release condition is satisfied even though the player has won the special role.
On the other hand, in a slot machine that does not stock the winning of a special role, there is a problem that a game that does not win a special role continues indefinitely, and the player may have to continue to insert game media.

The problem to be solved by the present invention is that, in the RT gaming state, when the combination of symbols of special roles does not stop for a certain number of games, the game state is shifted to an advantageous gaming state over the previous RT gaming state. That is.

The present invention solves the above-described problems by the following means.
The present invention
The player determines the winning probability of a role including a replay that is a role for causing a player to replay and a special role that is a role for causing a player to perform a special game that is advantageous to the player. A first RT gaming state in which a lottery of a role is performed using a role lottery table in which a winning probability is set to a predetermined probability ;
A second RT game in which a winning probability of a combination including the replay and the special combination is determined, and a winning combination is performed using a combination lottery table in which the winning probability of the replay is set higher than the predetermined probability State and
RT game number counting means for counting the number of games in the first RT game state and the second RT game state,
In the first RT gaming state or the second RT gaming state, when the combination value of the special role does not stop and the count value by the RT game number counting means becomes a predetermined number or more, the first RT Transition to a gaming state that is different from the gaming state and the second RT gaming state and is more advantageous than the first RT gaming state and the second RT gaming state;
Furthermore, it has the case where it transfers to the said 2nd RT gaming state from the said 1st RT gaming state .

(Function)
In the present invention , the first RT gaming state in which the winning probability of replay is a predetermined probability and the second RT gaming state in which the winning probability of replay is higher than the predetermined probability are provided as gaming states. In any of these RT gaming states , when the number of games exceeds a predetermined number without stopping the combination of special role symbols, the gaming state becomes more advantageous than the previous RT gaming state. Transition .
Furthermore, there is a case where the first RT gaming state is shifted to the second RT gaming state.

Therefore, when the number of games reaches or exceeds a predetermined number of times without stopping the combination of symbols of the special role, since it until the game becomes advantageous gaming state than RT gaming state of is carried out, the player, the game media The game can be performed without being reduced from the previous game.
Furthermore, since there is a case where the first RT gaming state is shifted to the second RT gaming state, the game performance can be enriched.

(Relationship between the above solution and the embodiment)
In a first RT gaming state where a lottery of a role is performed using a winning lottery table in which a winning probability of replay is set to a predetermined probability, in the following embodiment, a winning where the winning probability of replay is set to 1 / 7.3 This corresponds to the first RT game using the lottery table 62C .
Further, in the second RT gaming state in which a lottery of a role is performed using a winning lottery table in which the winning probability of replay is set higher than a predetermined probability, the winning probability of replay is 1 / 7.2 in the following embodiment. This corresponds to the second RT game using the set combination lottery table 62D .
Furthermore, the predetermined number of games is 1000 games in the embodiment.
Furthermore, the advantageous gaming state corresponds to a normal game in the embodiment.

  In the present specification, the normal gaming state is used in a sense that does not include the RT gaming state. The RT gaming state is used to indicate at least one of the first RT gaming state or the second RT gaming state.

According to the present invention, when the combination of symbols of special roles does not stop for a certain number of games, it is possible to play a game without reducing game media than before by shifting the game state. .

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an outline of control of the slot machine 10 in the present embodiment.
(Game control means)
The game control means 60 of the slot machine 10 is means for comprehensively controlling the entire slot machine 10 including the progress and effects of the game of the slot machine 10, and includes lottery of the role, drive control of the reel 31, and payout at the time of winning. It controls the progress of the game and the output of the production. The game control means 60 is provided on the control board, and is a CPU that performs calculations, a ROM that stores programs necessary for the progress of the game, data for production, and the like, and when the CPU performs various controls. RAM etc. which memorize | store the data etc. which were taken in are temporarily stored.

(Bet switch, start switch, stop switch)
As shown in FIG. 1, a bet switch 40, a start switch 41, and a stop switch 42 are electrically connected to the input side (left side in FIG. 1) of the game control means 60.
The bet switch 40 is a switch that is operated when a player inserts a stored medal, and is a switch that enables an effective line by the operation. Although the medal insertion slot is not shown in FIG. 1, the medal insertion slot is a part for inserting an actual medal to activate the effective line, as with the bet switch 40. The insertion of the medal is included in the operation of the bet switch 40.

The start switch 41 is a switch operated by the player when starting the reel 31.
Furthermore, three stop switches 42 are provided corresponding to the three reels 31 and are operated by the player when stopping the corresponding reels 31.

(Motor, reel)
Peripheral devices such as the motor 32 described below are electrically connected to the output side (right side in FIG. 1) of the game control means 60.
The motor 32 is for rotating the reel 31, is connected to the center of rotation of the reel 31, and is controlled by the game control means 60.
The reel 31 has a ring shape, and a reel tape on which a plurality of types of symbols (such as symbols constituting a combination of symbols corresponding to a combination) is attached is attached to an outer peripheral surface thereof.

  In the present embodiment, three reels 31 are provided in parallel. Each reel 31 is arranged so that three symbols that are continuous in the vertical direction can be seen from a display window (not shown) provided on the front panel of the slot machine 10. Therefore, nine symbols are arranged so that a total of nine symbols can be seen from the display window of the slot machine 10.

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

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

  The lamps 21 are effects lamps for the slot machine 10 and are turned on in a predetermined pattern when predetermined conditions are satisfied. The lamp 21 includes a back lamp (not shown) arranged on the inner peripheral side of each reel 31, an upper lamp and a side lamp which are arranged on the front surface of the casing of the slot machine 10 and blink when a winning combination is made. A lamp (not shown) and the like are included.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
Furthermore, the image display device 23 includes a liquid crystal image display device, a dot display, and the like, and displays various effect images, predetermined information, and the like during the game.

(Design combination line, effective line)
Although not shown, a symbol combination line (effective line) is provided in a portion including the display window of the slot machine 10.
Here, the “symbol combination line” is a line of symbols when the reel 31 is stopped, and is a line that forms a combination of symbols. In the present embodiment, it is composed of a total of five lines: lines provided respectively in the middle, upper, and lower stages in the horizontal direction, and diagonal lines in the downward and leftward diagonal directions. The three symbols that are continuous above and below each reel 31 are positioned on one or more symbol combination lines.

Further, among the five symbol combination lines, an effective line and an invalid line are set from the symbol combination lines according to the number of medals inserted or set by the player.
Here, in the present embodiment, the “effective line” is a line for winning a combination when a combination of symbols corresponding to any combination stops on the line.

  On the other hand, the “invalid line” is generated when the number of inserted medals is other than three, and is a line that is not set as an effective line among the symbol combination lines, and a combination of symbols corresponding to any combination is that line. Even if it stops, the profit is not given according to the combination (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 number of medals inserted in one game is three (fixed) during the RT gaming state and the special game, and is one or three during the normal gaming state. When the number of medals inserted is 1, the horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbol combination lines are set as invalid lines. When the number of inserted medals is 3, all symbol combination lines (a total of 5) are set as valid lines, and there are no invalid lines.
In the present embodiment, it is set so that a game cannot be performed when the number of inserted medals is two. However, the present invention is not limited to this, and a game can be performed when the number of inserted medals is two. good. In this case, it is possible to set the horizontal, middle, upper and lower symbol combination lines (a total of three) as valid lines and the other two symbol combination lines as invalid lines.

(Role)
FIG. 2 is a diagram showing combinations of combinations of types (combinations drawn by the combination lottery means 61 described later), the number of payouts, and the like in this embodiment. As shown in FIG. 2, BB and RB which are special roles, small roles 1, small roles 2 and 3 which are small roles, replays, and RB transitional roles are provided.

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

Furthermore, a small combination is a combination in which a predetermined number of medals are paid out. In this embodiment, three types of small combination 1, small combination 2, and small combination 3 are provided. The combination of symbols and the number of payouts at the time of winning are set differently for each small role. Note that “any” in the small part 1 means that any symbol may be used.
Furthermore, the replay is a replaying role that enables a replaying game in which the number of medals inserted in the game is maintained.
The RB transition combination is a combination that is drawn in the BB general game, and when the RB transition combination wins, the RB game is executed from the next game.

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

  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”.

  As described above, the winning of the special role is carried over, but no role other than the special role is 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.

  In addition, as shown in FIG. 2, combinations of symbols of the reel 31 corresponding to the various types of roles described above are determined in advance. When all the reels 31 are stopped, the combination of symbols corresponding to any of the combinations stops on the active line, and when the winning combination of the combination is won, the number of medals corresponding to the combination is paid out.

  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, 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 and displayed in the vertical direction 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 reels 31 stopped on the effective line matches a predetermined combination of symbols of the winning 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.
(Role lottery means)
The role lottery means 61 performs lottery for a role (special role, small role, replay, and RB transition role described above). The role lottery means 61 is based on, for example, a random number generation means (hardware random number, etc.) for a role lottery, a random number extraction means for extracting a random number generated by the random number generation means, and a random value extracted by the random number extraction means. And determining means for determining the presence / absence of a winning combination and the winning combination.

  The random number generation means 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 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.

(Role drawing table)
The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. Further, the role lottery table 62 is displayed for each gaming state (in normal gaming (non-inside / inside), in the first RT game, in the second RT game, in the BB general game, in the RB game), and for the number of inserted medals. In addition, a special combination lottery table 62 is provided.

FIG. 3 is a diagram showing these combination lottery tables 62. In FIG. 3, the value shown in parentheses means the winning probability.
First, during the normal game, the first RT game, and the second RT game, the number of medals inserted is set to be one or three. In other games (BB game, RB game), the number of inserted medals is fixed at three.
In FIG. 3, a combination lottery table 62A is a combination lottery table 62 that is used in a non-internal game, and is used when the number of inserted medals is three. In the winning lottery table 62A, the winning probability of replay is set as high as 1/2. For this reason, when a game is played using the combination lottery table 62A, the replay is frequently won and won, so that the game can be played with almost no reduction in the number of medals owned. Further, the winning area for the small role 3 is not provided in the winning lottery table 62A.

  Further, the combination lottery table 62B is a combination lottery table 62 that is used in a non-internal game, and is used when the number of inserted medals is one. In the combination lottery table 62B, the winning probability of replay is set to 1 / 7.3 and a winning area for the small combination 3 is provided as compared with the combination drawing lottery table 62A. The winning probability of the small role 3 is set as high as 1 / 1.5.

Furthermore, the combination lottery table 62C is a combination lottery table 62 used during the first RT game, and is used when the number of inserted medals is three, and the winning probability of replay is 1/7. .3 is set.
Further, the role lottery table 62D is a role lottery table 62 used during the second RT game, and is used when the number of inserted medals is 3, and the winning probability of replay is determined by the role lottery table 62C. Is set to 1 / 7.2 which is almost equal to 1 / 7.3 which is the winning probability of replay.

  The role lottery table 62E is a role lottery table 62 used in the normal game, and is used when the number of inserted medals is 3. Compared with the role lottery table 62A, The winning areas of BB and RB are set as non-winning areas. Furthermore, the replay winning probability is set to 1 / 7.3.

Further, the combination lottery table 62F is a combination lottery table 62 used during the BB general game. In addition to the small combination 1 and the small combination 2, a winning region for the RB transition combination is provided.
The role lottery table 62G is a role lottery table 62 used during the RB game, and only the winning areas of the small role 1 and the small role 2 are provided.

  Note that even during the first RT game, the second RT game, and the inside of the normal game, it is possible to play with only one medal inserted, corresponding to the role lottery tables 62C, D, and E, respectively. A combination lottery table 62 for loading one sheet is provided. The winning lottery table 62 is provided with a winning area for the small role 3 like the winning lottery table 62B.

  As described above, 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. It is set to a predetermined ratio so as to have a winning probability set in advance.

If the winning combination BB or RB is won during a game in which the winning lottery tables 62A to 62D are used, the winning lottery table 62E is used until the winning BB or RB wins after the next game ( Normal game inside). When the winning BB wins during the game in which the role lottery tables 62A to 62E are used, the next game is in the BB general game, and the role lottery table 62F is used. If the RB transition combination wins during the BB general game, the next game is changed to the RB game, and the combination lottery table 62G is used.
In addition, when a winning RB wins during a game in which the role lottery tables 62A to 62E are used, the RB game is executed after the next game, and the role lottery table 62G is used.

(Means to carry over special roles)
The special combination winning means 63 is a game until the combination of symbols corresponding to the selected special combination stops on the active line when the special combination (BB and RB) is won (until the selected special combination wins) In this case, the winning of the special role is controlled to be carried over after the next game.
In the present embodiment, when a special combination is won, a special combination flag 63a is provided in order to store the selection of the special combination. When the special combination is won, the special combination flag 63a is turned on (from OFF). For example, when the BB is won, the special combination flag 63a related to the BB is turned on, and when the RB is won, the special combination flag 63a related to the RB is turned on. The ON state of the special combination flag 63a is maintained until the special combination wins, and when the special combination wins, the special combination flag 63a is turned from ON to OFF.

(Reel control means)
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 stores the stop position determination table 65 based on the lottery result of the winning combination by the winning lottery means 61 when the stop switch 42 is operated and the timing when the stop switch 42 is operated. With reference to this, the stop position of the reel 31 corresponding to the stop switch 42 is determined, and the motor 32 is driven and controlled so that the reel 31 is stopped 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 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, the number of symbols is set within 5 symbols including 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.

(Stop position determination table)
The stop position determination table 65 determines the stop position of the symbol of the reel 31 from the lottery result of the combination by the combination lottery means 61 and the position of the reel 31 at the moment when the stop switch 42 is operated. That is, the position where the stop switch 42 should be stopped with respect to the position at the moment when the stop switch 42 is operated is determined one-to-one.

Next, the relationship between the symbol arrangement on the reel 31 and the stop control of the reel 31 in this embodiment will be described.
FIG. 4 is a plan view showing a symbol arrangement on the outer peripheral surface of each reel 31 in the present embodiment. FIG. 4 shows a symbol arrangement of “RP” and “Bell”, and illustrations of symbols relating to other roles (“7”, “BAR”, “Cherry”) are omitted.

  As shown in FIG. 4, on each reel 31, the symbols “RP” and “bell” are all arranged at intervals within 5 symbols. Therefore, the symbols “RP” and “Bell” are arranged on the reel 31 at intervals within the range of the stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). As a result, at the time of winning the replay, the small role 2, the small role 3, or the RB transitional role, regardless of the position of the reel 31 at the moment when the stop switch 42 is operated, the winning replay, the small role 2, It is possible to control the combination of the symbols of the small combination 3 or the RB transition combination to be stopped on the active line.

(Stop symbol judging means)
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 stop symbol determining means 66 does not determine the symbol combination after the reels 31 actually stop, but the reels are determined by the stop position determination table 65 from the position of the reels 31 at the moment when the stop switch 42 is operated. It is also possible to determine the combination of symbols on the active line when 31 stop positions are determined.

(Payment means)
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.

(Special game control means)
The special game control means 68 starts the special game (BB game and RB game) (transition from the normal game to the special game), proceeds the game during the special game, and ends the special game (from the special game to the normal game). ) And the like.

  The special game control means 68 shifts from the normal game to the BB game when the symbol combination corresponding to BB stops on the active line. Further, when the combination of specific symbols corresponding to RB stops on the active line, the game is shifted from the normal game to the RB game.

First, during the normal game, when the symbol combination corresponding to BB stops on the active line, BB is won and the BB game is started from the next game.
In the BB game, a BB general game is played first. In the BB general game, the lottery of the combination is performed using the combination lottery table 62F. When the RB transition combination is won and won during the BB general game, the RB game is performed from the next game.

  The RB game is a game in which a lottery of a role is performed using the role lottery table 62G, and is a game that is executed until the number of winning a winning combination reaches 8 times or the number of games reaches 12 times. is there. During the RB game, the special game control means 68 counts the number of winning combinations and the number of games of the winning combination, and if either one is satisfied, the RB game is terminated, and control is performed so as to shift to the BB general game again. To do. As described above, during the BB game, the BB general game and the RB game are repeated.

In the present embodiment, as the BB game end condition, the number of medals paid out during the BB game is set to 450 or more.
Therefore, in this embodiment, the special game control means 68 counts the number of medals paid out during the BB game, and keeps updating the number of coins paid out for each game.
When the special game control means 68 determines that the counted number of payouts is 450 or more, it determines that the BB game end condition is satisfied.

  Further, the special game control means 68 controls to shift to the RB game on the condition that the combination of symbols corresponding to the RB has stopped on the active line, that is, the RB has won. The RB game is a game that is executed until the number of winning combinations reaches 8 or until the number of games reaches 12. During the RB game, the special game control means 68 counts the number of winning combinations and the number of games of the winning combination, and if either one is satisfied, the special game control means 68 controls to end the RB game and shift to the normal game.

(Game state control means)
The gaming state control means 69 controls whether the gaming state is set to the normal gaming state or the RT gaming state.
The RT game of the present embodiment has a first RT game and a second RT game.
First, the first RT game is a game executed after the end of the special game (BB game or RB game). In the first RT game, the winning lottery is performed using the winning lottery table 62C.
The second RT game is a game that is executed from the next game when the small role 3 wins / wins during the normal game. In the 2nd RT game, the lottery of the combination is performed using the combination lottery table 62D.

Furthermore, the gaming state control means 69 includes an RT flag 69a. The RT flag 69a is a flag referred to for determining whether or not the game is an RT game, and includes an RT flag 69a related to the first RT game and an RT flag 69a related to the second RT game.
When the first RT game is executed, the RT flag 69a related to the first RT game is turned on, and at the end of the first RT game, the RT flag 69a is turned off. Similarly, the RT flag 69a related to the second RT game is turned on when the second RT game is executed, and the RT flag 69a is turned off at the end of the second RT game.

  Further, in the present embodiment, one of the end conditions of the first RT game and the second RT game is that “the number of games is (continuously) 1000 games or more in a state where the special role is not won”. It has been.

Therefore, the game state control means 69 includes RT game number counting means 69b.
The RT game number counting means 69b counts each game and the number of games when the (first or second) RT game is being performed.
When the (first or second) RT game is being performed and the number of games reaches 1000 or more in the state where the special role has not been won, the game state control means 69 It is determined that the end condition is satisfied, the RT flag 69a is turned off, and the game state is controlled to shift to the normal game.

  If the game shifts to the normal game, the replay wins / wins with a probability of 1/2, so that the player can continue to play the game with almost no reduction in the number of medals and wait for the special role to be won. As a result, when the number of games becomes 1000 or more in a state where the special role is not won, it is possible to create a gaming state similar to the so-called ceiling function of the slot machine by shifting to a gaming state in which the winning probability of replay is increased. it can.

In addition, as one of the end conditions of the first RT game and the second RT game, “having won the special role” is provided.
If the special role is won during the first RT game or the second RT game, the RT game is terminated in the game, and the game after the next game becomes the game in the special role.

In the present embodiment, setting values for the slot machine are provided. The setting value is provided in six stages (setting 1 to setting 6), and any one setting value is set. The set value is stored in a RAM or the like. Different role lottery tables 62 are used according to the set values. For example, the higher the set value, the higher the probability of winning the special role.
The role lottery tables 62A to 62D shown in FIG. 3 exemplify the winning probabilities of the winning combinations corresponding to any one of the payout rate setting values. Each has a combination lottery table 62A-62D.

  When the set value is changed and the slot machine 10 is reset, a normal game (not inside) is entered. Therefore, it is a game in which the combination lottery table 62A is used. In this case, since the winning probability of replay is high (1/2) from the beginning, the store where the slot machine 10 is installed becomes disadvantageous. Therefore, the store where the slot machine 10 is installed changes the setting and then plays a game with the number of inserted medals set to one. Thereby, it becomes a game in which the combination lottery table 62B is used.

  In this gaming state, since the winning probability of the small combination 3 is 1 / 1.5, in most cases, the small combination 3 wins / wins within a few games. In the next game of the game in which the small role 3 is won, it becomes the second RT game (game in which the role lottery table 62D is used), and the winning probability of the replay is almost equal to the first RT game (the winning probability is 1 / 7.2). It becomes a game. Therefore, the small role 3 can be used to eliminate the disadvantage of the store where the slot machine 10 is installed.

  In addition, even during the first RT game, the second RT game, and the inside of the normal game, it is possible to play with one medal inserted, but in these gaming states, the small role 3 is won and won. However, there is no game state transition.

Next, a game flow in the present embodiment will be described based on a flowchart.
FIG. 5 and FIG. 6 are flowcharts showing the flow of processing during the normal game (inside / inside) and during the first and second RT games. FIG. 6 is a flowchart following FIG.

  In step S11 of FIG. 5, the game control means 60 continues to detect whether or not medals have been inserted. And when insertion of a medal is detected, such as operating the bet switch 40, it progresses to step S12. In step S12, the game control means 60 continues to detect whether the start switch 41 is turned on. When ON is detected, an effective line is set according to the number of inserted medals, and the process proceeds to step S13. In step S13, the game control means 60 determines whether or not the RT flag 69a (related to the first RT game or the second RT game) is on.

  If the RT flag 69a is on, the process proceeds to step S16. If not, the process proceeds to step S14. In step S14, the game control means 60 determines whether or not the special combination flag 63a is on. When it is determined that it is on, the process proceeds to step S20, and when it is determined that it is not on, the process proceeds to step S15. In step S15, it is determined whether or not the number of medals inserted in the game is one. When it is determined that the number is one, the process proceeds to step S19. When it is determined that the number is not one (three), the process proceeds to step S18.

  In step S18, the combination lottery table 62A is set as the combination lottery table 62 used in the game. Then, the process proceeds to step S23. On the other hand, when the process proceeds from step S15 to step S19, the part lottery table 62B is set as the part lottery table 62 used in the game. Then, the process proceeds to step S23. Further, when the process proceeds from step S14 to step S20, the part lottery table 62E is set as the part lottery table 62 used in the game. Then, the process proceeds to step S23.

  Further, when proceeding from step S13 to step S16, the RT game number counting means 69b performs a process of adding 1 to the game number N (N = N + 1). Next, the process proceeds to step S17, where it is determined whether or not the first RT flag (RT flag related to the first RT game) 69a is on. If it is determined to be on, the process proceeds to step S21, and if it is determined that it is not on (the RT flag 69a related to the second RT game is on), the process proceeds to step S22. In step S21, a combination lottery table 62C is set as the combination lottery table 62 used in the game. Then, the process proceeds to step S23. On the other hand, in step S22, the role lottery table 62D is set as the role lottery table 62 used in the game. Then, the process proceeds to step S23.

In step S23, the combination lottery means 61 performs a combination lottery using the combination lottery table 62 set in steps S18 to S22. In the next step S24, the reel control means 64 performs control so as to start the rotation of all the reels 31.
Next, proceeding to step S25, the game control means 60 determines whether or not the special combination is won in the combination lottery at step S23. When it is determined that the player has won, the process proceeds to step S26. When it is determined that the player has not been won, the process proceeds to step S28. In step S26, the special combination winning carry-over means 63 turns on the special combination flag 63a. In the next step S27, the game state control means 69 turns off the RT flag 69a when the RT flag 69a is on in the game. Then, the process proceeds to step S28.

In step S28, the reel control means 64 sets a stop position determination table 65 corresponding to the winning combination of the game. In the next step S29, the game control means 60 continues to determine whether or not the stop switch 42 is turned on. When it is determined that the stop switch 42 is turned on, the process proceeds to step S30, and the reel control means 64 controls the drive of the motor 32 to perform the stop control of the reel 31 corresponding to the turned on stop switch 42.
Next, proceeding to step S31, the game control means 60 determines whether or not all the reels 31 have stopped, and when determining that they have stopped, proceeds to step S32. On the other hand, when it is determined that all the reels 31 have not stopped yet, the process returns to step S29.

  In step S32, the stop symbol determining means 66 determines whether or not any winning combination has been won (whether or not the combination of symbols corresponding to any winning combination has stopped on the active line), and determines that winning has been won. If so, the process proceeds to step S33, and if it is determined that no winning is made, the process proceeds to step S37. In step S33, the payout means 67 performs a process such as paying out medals according to the winning combination. For example, when the small combination 2 wins, the number of medals corresponding to the small combination 2 (10) is paid out. Then, the process proceeds to step S34. Note that at the time of winning a BB or RB, as shown in FIG. 2, no payout process in step S33 is performed because no medal is paid out.

  In step S34, the stop symbol determination means 66 determines whether or not the special combination has won. When it is determined that the special combination has won, the process proceeds to step S40, and when it is determined that the special combination has not been won, the process proceeds to step S35. In step S35, the stop symbol determination means 66 determines whether or not the small combination 3 has won a prize in the game. When it is determined that a prize has been won, the process proceeds to step S36, and when it is determined that a prize has not been won, the process proceeds to step S37. In step S36, the gaming state control means 69 turns on the RT flag 69a related to the second RT game, and proceeds to step S37. Here, the processing of step S36 is performed only when the small combination 3 wins / wins as a result of playing a game by inserting one medal into the non-inside of the normal game. That is, even if the small role 3 wins / wins as a result of the game being played with one medal inserted during the first RT game, the second RT game, or the inside of the normal game, the process of step S36 is Not done.

In step S37, the game state control means 69 determines whether or not the number N of games has reached 1000 or more when the game is the first RT game or the second RT game. When it is determined that the number is 1000 times or more, the process proceeds to step S38, and when it is determined that the number is not 1000 times or more, the process according to this flowchart is terminated.
In step S38, the gaming state control means 69 turns off the RT flag 69a, and in the next step S39, the number of games N is initialized (N = 0). And the process by this flowchart is complete | finished.

  On the other hand, when proceeding from step S34 to step S40, the special combination winning carry-over means 63 turns off the special combination flag 63a related to the special combination won. In the next step S41, the game state control means 69 turns off the RT flag 69a when the RT flag 69a is on in the game. In the next step S42, the special game control means 68 executes a special game. When this special game ends and the process proceeds to step S43, the gaming state control means 69 turns on the RT flag 69a related to the first RT game and proceeds to step S39. In step S39, the number N of RT games is initialized as described above, and the processing according to this flowchart ends.

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) In this embodiment, medals are used as game media, but the present invention can be applied to slot machines using game media other than medals, such as slot machines (parrots) using game balls. .
(2) In this embodiment, the first RT game and the second RT game are provided as the RT game state, but only one common RT game may be provided. Conversely, three or more types of RT games may be provided. When an RT game is further provided, the winning probability of the replay may be different from the replay winning probability of the other RT games but may be approximately equal.

  (3) The replay winning probabilities X1 and X2 can be variously set without being limited to the values shown in the present embodiment. However, in the normal gaming state, it is preferable to have a gaming state in which medals are hardly reduced or a slightly increasing gaming state, and the winning probability X1 is set within a range of, for example, 1 / 1.5 to 1 / 2.5. To do.

  (4) The combination of symbols of predetermined roles and the winning probabilities are examples, and can be variously set without being limited to those shown in the present embodiment. As a combination of symbols of a predetermined role, it is not always necessary to be able to win a prize when winning. In addition, the winning probability of the predetermined combination may be about 1/2 to 1/3. Furthermore, a case where two medals are inserted may be provided, and the predetermined combination may be drawn only when the number of inserted medals is two.
