Description

  The present invention relates to a slot machine in which the number of executions (or transition rate, etc.) of AT games differs according to a set value.

In a conventional slot machine, when a winning combination is made, the combination of symbols stopped on the active line differs according to the timing of the stop switch operated by the player or the order of pressing, and the player depends on the combination of symbols stopped on the active line. There is known a slot machine provided with a specific small role in which the benefits received by the customer are different.
When a predetermined condition is satisfied, a notification game (AT game) for notifying the operation information related to the operation timing or the pressing order of the stop switch, which is advantageous to the player, is performed when the specific small role is won. .

On the other hand, the slot machine has a plurality of setting values for determining the payout rate. On the hall side, one of the set values is determined in consideration of how much to play on the day. Yes.
In a plurality of different set values, the winning probabilities for the small role and the replay are almost the same, but the winning probabilities for special roles such as BB are generally different.
In addition, since the payout rate is determined according to the set value, in a slot machine provided with AT games (notification games), the rate of transition from non-AT games to AT games, the number of AT games continued, the number of AT games The number of medals that can be acquired in AT games, such as the number of games, is set to increase as the set value increases (see, for example, Patent Document 1).

JP 2003-210661 A

As in the above-mentioned conventional technology, the game play rate of the slot machine is determined according to the set value. Naturally, the number of executions of the AT game and the transition rate are set so that the higher the set value, the more advantageous it is. Has been.
For this reason, the payout rate of the slot machine is ultimately deeply influenced by the setting value of the day.
On the other hand, since the winning probability of special roles and the number of executions of AT games differ for each set value, the player can check the setting value of the slot machine by checking the number of executions of special games and AT games on that day. I was able to predict.
For this reason, the operating rate of a slot machine that is presumed to have a high setting value is high, but in a slot machine that is presumed to have a low setting value, the player may refrain from playing the game and the operating rate may decrease. It was.

  Therefore, the problem to be solved by the present invention is that the number of executions (or transition rate, etc.) of the AT game is not affected only by the setting value of the day while maintaining that the higher the setting, the higher the payout rate. By doing so, it is to give an appropriate wave to the appearance rate of the slot machine, and to increase the operating rate.

The present invention solves the above-described problems by the following means. Note that the corresponding embodiment is shown in parentheses.
The invention of claim 1
A plurality of reels (31) displaying a plurality of types of symbols;
Setting means (setting change switch 44, setting value changing means 60) for setting any one of a plurality of setting values having different expected values for medal acquisition ;
A role lottery means (61) for drawing a role including special roles (BB and RB) ;
When the reel rotation start command is received (when the start switch 41 is operated), the reel starts rotating, and when the stop switch (42) is operated by the player, the combination lottery means Reel control means (64) for controlling to stop the reel corresponding to the stop switch at a position based on the lottery result of the combination,
The combination lottery means, when winning the combination, the combination of symbols that stop on the active line according to the operation timing or pressing order of the stop switch by the player is different, and operation information related to the operation timing or pressing order of the stop switch Is notified, it is possible to increase the probability that a combination of symbols advantageous to the player stops on the active line than when the operation information is not notified (small role 2, replay 1 to replay 3). A lottery of roles including
As a gaming state, there is a notification game (AT game) for notifying the operation information when the specific combination is won by the combination lottery means,
When the condition for storing the number of executions of the notification game is satisfied, a predetermined number of times or a number determined by lottery is added to the number of times stored so far (notification game number storage means (AT game number storage means) 71a)
When the conditions for executing the notification game are satisfied, the predetermined number of times or the number of times determined by lottery is determined as the number of executions of the notification game, and from the number of times stored in the notification game number storage means, Notification game number determination means (AT game number determination means 71b) for subtracting the determined number of executions,
When the special combination is won by the combination lottery means, the special combination selection carry-over for controlling the special combination to be carried over after the next game until the combination of symbols corresponding to the special combination stops on the active line. Means (63),
In the game (internal game) until the combination of symbols corresponding to the special combination is stopped on the effective line after the special combination is won by the combination lottery unit, The lottery of whether or not to store the number of executions is controlled, and the probability of winning the lottery for storing the number of executions of the notification game is controlled according to the set value ,
In the case where the number of executions of the notification game is stored by the notification game number storage unit, when the specific combination (replay 2) is won by the combination lottery unit, it is determined to execute the notification game. It is characterized by.

(Function)
In the invention of claim 1, during the game, the number of storage is added by lottery or the like by the notification game number storage means. In particular, in the internal game until the combination of symbols corresponding to the special role is stopped on the active line after the special role is won (the special role is won), a lottery of whether or not to store the number of executions of the notification game is determined. Done.
Here, the probability of winning the lottery for storing the number of executions of the notification game differs depending on the set value, for example, between a low setting such as setting 1 and a high setting such as setting 6 .
On the other hand, when the condition for executing the notification game is satisfied, the number of executions of the notification game is determined.

According to the first aspect of the present invention, for example, when the setting is low, the notification game is difficult to be executed but easily stored, and when the setting is high, the notification game is difficult to be stored but is easily executed. Therefore, for example, the notification game is more easily executed at the high setting after the low setting continues for several days than at the high setting when the high setting state continues for several days.
Also, in the so-called internal game, the probability of winning the lottery for storing the number of executions of the notification game and winning the lottery for storing the number of executions of the notification game varies depending on the set value. The game length (player level), the number of storages of the number of executions of the notification game, and the set value can be provided.
Thereby, it can be set as the appearance which does not depend only on a setting value on the day.

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. The slot machine 10 includes a game (main) control means 50 and an effect (sub) control means 70.

  The game control means 50 controls the progress of games such as winning lottery, reel 31 drive control, and payout at the time of winning, and is provided on a main control board (not shown). A CPU for performing a game, a ROM for storing a program necessary for the progress of the game, a RAM for temporarily storing data taken in when the CPU performs various controls, and the like.

The effect control means 70 controls the output of game information and game information during the game and in the game standby. The effect control means 70 is provided on a sub-control board (not shown), and a CPU that performs calculations, a ROM that stores data for effects (such as effect patterns), and a CPU perform various effects. A RAM or the like for temporarily storing data taken in when outputting is provided.
The sub control board is a control board belonging to a lower level of the main control board. The game control means 50 and the effect control means 70 are electrically connected, and are configured so that signals and information (commands) are transmitted from the game control means 50 to the effect control means 70 in one direction. .

As shown in FIG. 1, a bet switch 40, a start switch 41, a stop switch 42, and a setting change switch 44 are electrically connected to the input side (left side in FIG. 1) of the game control means 50.
The bet switch 40 is a switch operated when the player inserts a stored medal for the game. The bet switch 40 in this embodiment is a switch dedicated to throwing in three (max), and the player always throws in three medals in any gaming state (normal game and special game). Is supposed to do.
The medal slot 43 is a part where the player inserts an actual medal, and inserting a medal from the medal slot 43 has the same role as operating the bet switch 40.

The start switch 41 is a switch operated by the player when starting the reels 31 (all of left, middle and right).
Furthermore, three (left, middle, right) stop switches 42 are provided corresponding to the three (left, middle, right) reels 31, and the player operates to stop the corresponding reels 31. Switch.
Further, the setting change switch 44 is operated when changing / setting the setting value of the slot machine 10. There are six setting values from setting 1 to setting 6, and the setting value is set such that the higher the setting value, the more advantageous for the player (the higher the payout rate). The setting change switch 44 is not operated by the player, but is operated at the store (hall) side of the slot machine 10 and is disposed inside the slot machine 10 so that it cannot be operated by the player. ing.

Three motors 32 are electrically connected to the output side (right side in FIG. 1) of the game control means 50.
The motor 32 is for rotating the reels 31, is connected to the center of rotation of each reel 31, and is controlled by a reel control means 64 described later. Here, the reel 31 includes a left reel 31, a middle reel 31, and a right reel 31, and a stop switch 42 that is operated when the left reel 31 is stopped is the left stop switch 42, and when the middle reel 31 is stopped. The stop switch 42 to be operated is the middle stop switch 42, and the stop switch 42 to be operated when stopping the right reel 31 is the right stop switch 42.

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

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

  In this specification, in FIG. 3, the positions where the “watermelon” of the left reel 31 and the “red cherry” symbols of the middle and right reels 31 are stopped are “upper”, and the positions of the left, middle and right reels 31 are stopped. The position where the “red 7” symbol is stopped is “middle”, the “bell” symbol of the left and right reels 31 and the “white cherry” symbol of the middle reel 31 are “lower”. Called.

Furthermore, as shown in FIG. 3, effective lines L <b> 1 to L <b> 4 are provided in a portion including the display window 11 of the slot machine 10.
Here, the “effective line” is a symbol combination line that forms a symbol combination when the reel 31 is stopped, and a symbol combination corresponding to any of the combinations is the line. It is a line that will be the winning prize of that role when stopped. In the present embodiment, as shown in FIG. 3, the effective line L1 in the upper horizontal direction, the effective line L2 in the middle in the horizontal direction, the effective line L3 in the slanting right-down straight line, and the effective line L4 in the slanting right-up straight line are configured. .

  In addition, as a feature of the effective line of the present embodiment, a position through which the effective line passes in the middle reel 31 can be cited. An effective line passing through the lower stage of the middle reel 31 is not provided in this embodiment. The effective line passing through the upper stage of the middle reel 31 is one effective line L1. Furthermore, the effective lines passing through the middle stage of the middle reel 31 have three effective lines L2, L3, and L4.

  In this embodiment, all the symbol combination lines other than the valid lines L1 to L4 are invalid lines. For example, in FIG. 3, a symbol combination line that passes through the lower stage of each of the left reel 31, the middle reel 31, and the right reel 31 is also conceivable, but such a line is an invalid line in the present embodiment. An invalid line is a line that is not set as a valid line among symbol combination lines, and even if a combination of symbols corresponding to any of the combinations stops on that line, a profit corresponding to the combination is given. This line does not perform (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.

  Conventionally, there are known slot machines in which the number of effective lines differs according to the number of medals inserted. For example, when the number of inserted medals is 1, the number of effective lines is set to 1. When the number of inserted medals is 2, the number of effective lines is set to 3. When the number of inserted medals is 3, the number of effective lines is set to 5. And so on. On the other hand, in this embodiment, in any game, three medals are inserted and a game is played, and in all games, all four effective lines L1 to L4 are effective lines in the game. It becomes.

Further, in FIG. 1, production output devices such as the lamp 21, the speaker 22, and the image display device 23 are electrically connected to the output side of the production control means 70.
The lamps 21 are effects lamps for the slot machine 10 and are turned on in a predetermined pattern when predetermined conditions are satisfied. The lamp 21 is arranged on the inner peripheral side of each reel 31 and is a back lamp (not shown) for illuminating from behind the symbols displayed on the reel 31 (three symbols that are continuously visible from the display window 11). ), And an upper lamp and a side lamp (not shown) which are arranged on the front surface of the housing of the slot machine 10 and blink when a winning combination is made.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
Furthermore, the image display device 23 is composed of a liquid crystal display, a dot display, or the like, and displays various effect images during the game, the order of pressing the stop switch 42 during the AT game described later, and the like.

FIG. 4 is a diagram showing combinations of types (combinations lottered by the combination lottery means 61 described later), the number of payouts, and the like that can be stopped on the active line in this embodiment. As shown in FIG. 4, the roles are roughly classified into a special role, a small role, a control role, and a replay.
A combination of symbols corresponding to each combination and the number of payouts at the time of winning are determined. As a result, when all the reels 31 are stopped, when the combination of symbols corresponding to any of the combinations stops on the active line (the combination wins), the number of medals corresponding to the combination is paid out (however, Excluding special roles). Further, although the payout number is set to “0”, the control combination does not stop at the active line as will be described later.

In the combination, first, the special combination is a combination that shifts from the normal game to the special game. In the present embodiment, as shown in FIG. 4, BB (first type big bonus), RB (regular bonus), and SB (single bonus) are provided as special roles.
When BB, RB, and SB win, there is no payout of medals in the game, but the next game shifts to BB game, RB game, and SB game, which are special games. The special game is an advantageous game for the player who can expect to win medals more than the normal game because the payout rate is set to exceed 1.

In this embodiment, two types of BBs, BB1 and BB2, are provided, and the combinations of symbols are set differently.
Similarly, in this embodiment, two types of RBs, RB1 and RB2, are provided, and the combinations of symbols are set differently.

  Other special roles include MB (middle bonus, also referred to as a second type big bonus), which is not provided in this embodiment.

  A small role is a role in which a predetermined number of medals are paid out. In this embodiment, there are three types of small roles 1 to 3 and a combination of symbols for each small role. Are set differently. Note that “any” in the small combination 1 and the small combination 2 means an arbitrary symbol. That is, for example, in the small combination 2, when the symbol “bell” of the middle reel 31 stops at any of the effective lines (upper or middle), regardless of the stopped symbol of the left reel 31 and the right reel 31, 2 wins are finalized.

  Furthermore, as will be described later, the control combination is a combination set so as to overlap with the small combination 2 and does not stop at the active line even when winning. The control combination is a combination provided to change the effective line at which the combination of symbols corresponding to the small combination 2 stops according to the pressing order of the stop switch when the small combination 2 is won.

  Furthermore, the replay is a re-playing role that allows the re-playing while maintaining the number of medals inserted in the game (three in the present embodiment). In the present embodiment, the replay includes three types of replay 1 to replay 3, and is set so that the combination of symbols is different.

  Further, in FIG. 4, the number of payouts for each combination means the number of payouts per one effective line. That is, for example, when the combination of symbols corresponding to the small combination 2 stops on any one of the active lines, it means that the medal payout number is three. Therefore, when the combination of symbols corresponding to the small role 2 is simultaneously stopped on three active lines in the game, the number of medals paid out per effective line is multiplied by the number of effective lines. In that case, 9 tickets will be paid out.

Specifically, when the symbol “bell” stops at the upper stage when the middle reel 31 is stopped, the combination of symbols corresponding to the small part 2 is stopped on the active line L1 (one) in FIG. Therefore, 3 medals will be paid out.
On the other hand, when the symbol “bell” stops in the middle when the middle reel 31 is stopped, the combination of symbols corresponding to the small part 2 is stopped on the three active lines L2, L3 and L4 in FIG. Therefore, 3 medals x 3 = 9 medals are paid out.

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

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

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

  At the start of the game, the player operates the bet switch 40 to insert a previously stored medal, or inserts a medal from the medal insertion slot 43, and operates (turns on) the start switch 41. When the start switch 41 is operated, a signal generated at that time is input to the game control means 50. When the game control means 50 (specifically, the reel control means 64 described later) receives this signal, it controls to drive all the motors 32 and rotate all the reels 31. As the reel 31 is rotated by the motor 32 in this way, the symbols on the reel 31 are moved and displayed in the vertical direction in the display window 11 at a predetermined speed.

  Then, the player presses the stop switch 42 to stop the rotation of the reel 31 corresponding to the stop switch 42 (for example, the left reel 31 corresponding to the left stop switch 42). When the stop switch 42 is operated, a signal generated at that time is input to the game control means 50. When the game control means 50 (specifically, the reel control means 64 described later) receives this signal, the game control means 50 controls the drive of the motor 32 corresponding to the stop switch 42 and controls the stop of the reel 31 related to the motor 32. I do. When all of the reels 31 are stopped, when a combination of symbols corresponding to any of the combinations stops on the active line (when the winning combination of the combination is awarded), a medal corresponding to the winning combination is paid out. Done.

  As shown in FIG. 1, the game control means 50 includes the following set value changing means 60 and the like. The following means in the present embodiment are examples, and the game control means 50 is not limited to the means shown in the present embodiment.

  The setting value changing means 60 is for changing / determining a setting value that determines the payout rate of the slot machine 10. In particular, in this embodiment, six stages from setting 1 to setting 6 are provided as setting values, and the higher the setting value, the higher the payout rate (the higher the probability of winning the special role and the number of times AT games are executed). It is set so that there are many expected values).

In this embodiment, a power switch (not shown) provided on a power supply unit (not shown) is operated to turn it off, and a setting key is inserted into a setting key insertion slot (not shown) to rotate clockwise. Rotate 90 degrees. When the power is turned on in this state and the power is turned on, the setting change mode is set. Therefore, in this case, normal startup processing is not performed. Note that the setting key may be inserted into the setting key insertion slot, rotated 90 degrees clockwise, the power is turned off in this state, and the power may be turned on again.
In the setting change mode, the current setting value is displayed on a predetermined display unit.

  When changing the setting value, an operation of pressing the setting change switch 44 is performed. Each time the setting change switch 44 is pressed, the setting value is displayed as follows: → “1” → “2” → “3” → “4” → “5” → “6” → “1” → “1” 2 ”→... In this embodiment, the start switch 41 is turned on in a state where a desired setting value is obtained by pressing the setting change switch 44. With this operation, the set value is confirmed, and “0” is displayed on the predetermined display unit to indicate that the set value has been confirmed.

The set value changing means 60 is provided with a set value storage means 60a (memory such as RAM) for storing the set values, and stores the determined set values in the set value storage means 60a.
Next, turn off the power, turn the setting key 90 degrees counterclockwise (turn it off), turn it off and turn it on again, or turn the setting key 90 degrees counterclockwise and remove it, and then turn the power off. If the power is turned off and turned on again, a normal startup process with the changed set value is performed.
The set value stored in the set value storage means 60a is transmitted to the effect control means 70, and the set value is also set on the effect control means 70 side.

  The role lottery means 61 performs lottery for a role (the special role, the small role, the control 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 slot machine 10 is powered on. .

  The random number extraction means extracts the random number generated by the random number generation means at a predetermined time, in the present embodiment, when the start switch 41 is operated (turned on) by the player. The determination unit determines the combination corresponding to the region to which the random number value belongs by comparing the random number value extracted by the random number extraction unit with a combination lottery table 62 described later. For example, when the extracted random number value belongs to the winning area of BB1, it is determined that BB1 is won, and when it belongs to the non-winning area, it is determined not to win.

  The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. 5 and 7 are diagrams showing the role lottery table 62 (62A to 62F) in the present embodiment. The role lottery table 62 is provided for each gaming state. 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

First, the “game state” of the present embodiment includes a normal game and a special game. Further, the normal game includes a non-RT game, an RT1 game, an RT2 game, an RT3 game (all of which are non-inside inside games), and an inside inside game. The characteristics of these gaming states will be described later.
The special game includes a BB game, an RB game, and an SB game.

In the combination lottery table 62 of FIG. 5, “+” means duplicate (simultaneous) winning. For example, in FIG. 5, “BB1 + small role 1” means that BB1 and small role 1 will win (simultaneously) in the game.
In particular, in the present embodiment, BB and RB, which are special roles, are not elected alone, but are always duplicated with other roles (small role 1 or small role 3).
In addition, the control combination 1 to the control combination 3 are always the winning combination with the small combination 2.
Furthermore, Replay 1 and Replay 3 have a case of single winning and a case of overlapping winning. Furthermore, the replay 2 is set only for overlapping winning with the replay 1.

In addition, the small combination 2 is determined to have a case where it wins alone and a case where it overlaps with a control combination.
Furthermore, in FIG. 5, the probability of summing that the small combination 2 and any one of the control combinations wins is set to 1/10, and the winning probability is divided into five (5 equal parts). Therefore, the winning probability of the small role 2 + control role 1 is 1/50, the winning probability of the small role 2 + control role 2 is 1/50,..., And the winning probability of the small role 2 + control role 1 + control role 3 is 1/50. Is set to

  The role lottery table 62A is a role lottery table 62 used in non-RT games. In the combination lottery table 62A, there is no single winning of Replay 1 or Replay 3, but the overlapping winning of Replay 1 and Replay 2 and the overlapping winning of Replay 1 and Replay 3 are set. In the combination lottery table 62A, the combined winning probability of replay is set to a high probability of 7/10.

In addition, there are five overlapping winnings for replay 1 and replay 2 and 5 overlapping winnings for replay 1 and replay 3 (overlapping winning A to overlapping winning E). The winning probability shown in FIG. 5 is the sum of these values.
For example, the winning probability of the entire overlapping winning of Replay 1 and Replay 2 is set to 1/5, and this winning probability is divided into five (5 equal parts). That is, the duplicate winning A of Replay 1 and Replay 2 is set to 1/25, the overlapping winning B of Replay 1 and Replay 2 is set to 1/25,..., And the overlapping winning E of Replay 1 and Replay 2 is set to 1/25. ing.
The duplicate winning of Replay 1 and Replay 3 is set in the same manner as described above.

The role lottery table 62B is a role lottery table 62 used in the RT1 game. In the combination lottery table 62B, as compared with the combination lottery table 62A, only a single winning of the replay 3 is provided for replay.
Furthermore, the combination lottery table 62C is a combination lottery table used in the RT2 game. The winning lottery table 62C differs from the winning lottery table 62A in the winning probability of replay. The winning lottery table 62C has only a single winning of Replay 1, and the winning probability is set as high as 1 / 1.2.

  Further, the combination lottery table 62D is a combination lottery table 62 used in the RT3 game. The combination lottery table 62D differs from the combination lottery table 62C only in the winning probability of the replay 1. In the winning lottery table 62D, the winning probability of Replay 1 is 1 / 7.3.

  The role lottery table 62E is a role lottery table 62 used in internal games. Once a BB or RB is won in a non-inside of a normal game, the BB or RB wins and shifts to a special game, until the special game ends and shifts to a non-inside of a normal game. There will be no lottery. Therefore, in the internal middle game, only the small combination and replay are drawn.

FIG. 6 is a diagram showing the overlapping winning probability between BB or RB and the small combination 1 or small combination 3.
As shown in FIG. 6, the overlapping winning probability of BB or RB and the small combination 1 or small combination 3 is different for each set value (different set values may have the same winning probability). In particular, as the set value is higher (setting 6), the winning probabilities are set higher, and as the setting 1 is changed to the setting 6, the winning probabilities for special roles are gradually increased.

  These winning probabilities are common to non-RT games, RT1 games, RT2 games, and RT3 games. In addition, since BB and RB are not drawn in the internal game, the double winning probability between BB and small role 1 and the double winning probability between RB and small role 3 are the single winning of small role 1 and small role 3, respectively. It shows the probability. That is, the independent winning probability of the small role 1 in the inside is a form in which the winning probability of “BB1 + small role 1” and “BB2 + small role 1” is added to the winning probability of the small role 1 in the inside. . The same applies to the winning combination of RB1 or RB2 and the small role 3.

  Furthermore, the role lottery table 62F shown in FIG. 7 is a role lottery table 62 used in special games. In the role lottery table 62F, only small roles are drawn. In the combination lottery table 62F, the (single) winning probability of the small combination 2 is set to a high probability of 1 / 1.05 (so that almost every game is won).

Returning to FIG.
The winning flag control means 63 controls the on / off of the winning flag 63a corresponding to each winning, based on the winning lottery result by the winning lottery means 61. In the present embodiment, BB1, BB2, RB1, RB2, SB, small combination 1, small combination 2, small combination 3, control combination 1, control combination 2, control combination 3 corresponding to the winning combination (FIG. 4). 14 winning flags 63a of Replay 1, Replay 2, and Replay 3 are provided. When winning in the lottery of the combination by the combination lottery means 61, the winning flag 63a of the corresponding combination is turned on (the winning flag 63a is set).

  For example, when a small combination 1 is won in a non-internal medium game of a normal game, the winning flag 63a related to the small combination 1 is turned on, and the winning flags 63a of the other combinations remain off. Also, for example, in the case of a non-RT game of a normal game, when replay 1 and replay 2 are won simultaneously, the winning flag 63a related to replay 1 and the winning flag 63a related to replay 2 are turned on, and winning flags 63a related to other roles are turned on Remains off.

Furthermore, as described above, since winning of SB, small role, control role, and replay is not carried over, a small role, control role, and replay are won in the game, and the winning flag 63a of these roles is turned on. Even if the game is ended, the winning flag 63a is turned off at the end of the game.
On the other hand, since winning of BB and RB is carried over, when the game is won to BB (BB1 or BB2) or RB (RB1 or RB2), and the winning flag 63a related to BB or RB is once turned on The on state is maintained until the BB or RB wins, and is turned off when the BB or RB wins.

  For example, when the winning lottery means 61 overlaps BB1 and the small role 1 in the non-inside of the normal game, the two winning flags 63a of BB1 and the small role 1 are turned on, and at the end of the game, The winning flag 63a of the combination 1 is turned off, but the ON state of the winning flag 63a of BB1 is maintained (when BB1 is not winning in the game). Then, in the game inside the next game, for example, when winning the small combination 3, the winning flag 63a of the small combination 3 is turned on in addition to the winning flag 63a related to BB1 which is already on. Then, at the end of the game, the winning flag 63a related to BB1 is kept on, and the winning flag 63a of the small role 3 is turned off (when BB1 is not winning in the game).

  In FIG. 1, the reel control means 64 starts rotation of all (three) reels 31 when a rotation start command for the reels 31 is received, particularly when the start switch 41 is operated in this embodiment. To control. Further, the reel control means 64 refers to the ON / OFF of the winning flag 63a in the game after the winning lottery is performed by the winning lottery means 61, and the stop position determination table corresponding to ON / OFF of the winning flag 63a. 65, and when the stop switch 42 is operated, the stop position of the reel 31 corresponding to the stop switch 42 is determined based on the timing when the stop switch 42 is operated, and the motor 32 is turned on. Drive control is performed to stop the reel 31 at the determined position.

  For example, in a game in which at least one winning flag 63a is on, the reel control means 64 has a symbol corresponding to the winning combination (the combination for which the winning flag 63a is on) within the range of stop control of the reel 31. The reel 31 is controlled so that the combination can be stopped on the effective line, and the reel 31 is controlled so that the combination of symbols corresponding to a combination other than the winning combination (the combination in which the winning flag 63a is off) is not stopped on the effective line. Stop control.

  Here, “within the range of stop control of the reel 31” means within the range of the amount of rotation of the reel 31 (the number of moving symbols) from the moment when the stop switch 42 is operated until the reel 31 actually stops. In the present embodiment, the number of moving symbols from the symbol at the moment when the stop switch 42 is operated is set within 4 symbols (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). In other words, the time from when the stop switch 42 is operated to when the reel 31 actually stops is set within 190 ms.

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

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

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

  Further, the reel control means 64 includes a push order detecting means 64a for detecting the push order (operation order) of the stop switch 42. The push order detecting means 64a detects which one of the left, middle and right stop switches 42 is operated when the stop switch 42 is operated by the player. The push order detecting means 64a may detect the push order of the stop switch 42 every game, but in the present embodiment, when the small combination 2 and the control combination are won simultaneously, the replay 1 and the replay 2 It is detected whether the operated stop switch 42 is left, middle or right at the time of overlapping winning and when replay 1 and replay 3 are simultaneously winning.

  When the stop switch 42 is operated, a signal indicating that the stop switch 42 has been operated is input to the push order detecting means 64a. By discriminating this signal, the push order detecting means 64a detects which stop switch 42 has been operated.

  The stop position determination table 65 is provided for each on / off state of the winning flag 63a, that is, for each lottery result of the combination by the combination lottery means 61, and the reel 31 at the moment when the stop switch 42 is operated. The stop position of the reel 31 with respect to the position is determined. For example, for each winning combination shown in FIG. 5 and FIG. 7, “BB1 + small combination 1”, “BB2 + small combination 1”,..., “Replay 1 + replay 3 overlapping winning D”, “replay 1 + replay 3 overlapping Stop position determination tables 65 corresponding to “winning E” and “non-winning” are provided. In each stop position determination table 65, for example, when the stop switch 42 is operated at the moment when the symbol 0 (the symbol “RP” in the case of the left reel 31) passes the upper stage, how many symbols are moved. The stop position is determined such that the number of symbols is controlled to stop in the upper stage.

The stop position determination table 65 includes the following BB table and the like.
The BB1 table is used on condition that only the winning flag 63a of BB1 is on, that is, BB1 is won before the game and the game is not won, and within the range of the reel 31 stop control. The combination of symbols when the reel 31 is stopped is determined so that the symbol combination corresponding to BB1 is stopped on the effective line, and the symbol combinations corresponding to roles other than BB1 are not stopped on the effective line. .

  The BB2 table, the RB1 table, and the RB2 table are the same as the BB1 table. The BB2 table, the RB1 table, and the RB2 table correspond to those obtained by replacing “BB1” with “BB2”, “RB1”, and “RB2” in the BB1 table, respectively.

In the BB1 / small role 1 table, when the winning flag 63a of BB1 and small role 1 is on, that is, when BB1 and small role 1 are both won in a non-inside game, or in a game inside BB1 Used when winning 1 and prioritizes stopping the combination of symbols corresponding to the small role 1 on the effective line, and when the combination of symbols corresponding to the small role 1 cannot be stopped on the effective line Next, the symbol combination corresponding to BB1 is stopped on the effective line, and if the symbol combination corresponding to BB1 cannot be stopped on the effective line, the symbol corresponding to any combination In this combination, the stop position of the reel 31 is determined so as not to stop at the effective line.
It is also possible to set so that the combination of symbols corresponding to BB1 is given priority over the small combination 1 and stopped at the active line.

The BB2 / small role 1 table is the same as the BB1 / small role 1 table. The BB2 / small role 1 table corresponds to the above-described BB1 / small role 1 table in which “BB1” is replaced with “BB2”.
Furthermore, the RB1 / small role 3 table is the same as the BB1 / small role 1 table. The RB1 / pocket 3 table corresponds to a table in which “BB1” is replaced with “RB1” and “pocket 1” is replaced with “pocket 3” in the BB1 / pocket 1 table.
Further, the RB2 / small role 3 table is the same as the BB1 / small role 1 table. The RB2 / small role 3 table corresponds to a table in which “BB1” is replaced with “RB2” and “small role 1” is replaced with “small role 3” in the BB1 / small role 1 table.

The SB table is used when the SB winning flag 63a is ON, and within the range of the stop control of the reel 31, the combination of symbols corresponding to SB is stopped on the effective line and corresponds to a role other than SB. The combination of symbols when the reel 31 is stopped is determined so that the symbol combination is not stopped on the effective line.
Furthermore, when the combination of symbols corresponding to SB cannot be stopped on the effective line, control is performed so that the SB Koboshi is stopped on the effective line. Here, as shown in FIG. 4, the SB Koboshi is set to “bell”-“red cherry”-“bell” or “bell”-“BAR”-“bell”.

  When the SB table is used, the 12th “blue 7” design of the left reel 31, the 19th “red 7” design of the middle reel 31, and the 6th “blue cherry” design of the right reel 31 When each stop switch 42 is operated at a timing at which the symbols can be stopped on the effective lines, “blue 7”-“red 7”-“blue”, which is a combination of symbols corresponding to SB, is displayed on any effective line. Cherry "stops.

  On the other hand, when each stop switch 42 is operated at a timing other than the above, “bell”-“red cherry (or BAR)”-“bell”, which is the SB Koboshi, is stopped on any effective line. To do.

  The small combination 1 table is used when the winning flag 63a of the small combination 1 (only) is on, and stops the combination of symbols corresponding to the small combination 1 on the effective line within the range of stop control of the reel 31. At the same time, the combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the combination other than the small combination 1 is not stopped on the effective line.

In the small role 1 table, when the symbol of “red cherry” can be stopped at the upper stage when the left reel 31 is stopped, priority is given to stopping at the upper stage. If the symbol of “red cherry” stops in the upper stage, it means that it has stopped in two lines (effective lines L1 and L3), so two medals are paid out.
On the other hand, when the symbol “red cherry” cannot be stopped on the upper stage, the symbol “red cherry” is stopped on the middle or lower stage. In this case, the medal payout number is one.

The small role 2 table is a stop position determination table 65 that is used when only the winning flag 63a of the small role 2 (only) is on. Within the range of the stop control of the reel 31, the stop role 42 is pressed in the order of pressing. Regardless of the fact that the combination of symbols corresponding to the small role 2 is stopped on the effective line and the combination of symbols corresponding to the roles other than the small role 2 is not stopped on the effective line, The combination is determined.
Here, when the small role 2 table is used, the stop position of the reel 31 is determined so that the symbol “bell” is stopped at the middle stage when the intermediate reel 31 is stopped. Therefore, when the small combination 2 table is used, the payout number at the time of winning the small combination 2 is nine.

  The small combination 2 overlapping winning table A is used when the winning flag 63a of the small combination 2 and the control combination 1 is ON (when the small combination 2 + control combination 1 is selected), and within the range of the stop control of the reel 31, When the pressing order of the switch 42 is “left middle right”, the symbol combination corresponding to the small role 2 is stopped at the effective lines L2 to L4, that is, when the middle reel 31 is stopped, the symbol “bell” is displayed at the middle stage. The stop position of the reel 31 is determined so as to stop (9 medals are paid out).

On the other hand, when the pressing order of the stop switch 42 is other than “left middle right”, the combination of symbols corresponding to the small role 2 is stopped at the effective line L1, that is, when the middle reel 31 is stopped, “bell” is displayed at the upper stage. The stop position of the reel 31 is determined so as to stop the symbol (the payout of three medals).
In the above case, the combination of symbols corresponding to the control combination 1 does not stop on the active line.

  The small combination 2 overlapping winning table B is used when the winning flag 63a of the small combination 2 and the control combination 2 is ON (when the small combination 2 + control combination 2 is selected), and within the range of the stop control of the reel 31, When the pressing order of the switch 42 is “middle left and right”, the combination of symbols corresponding to the small role 2 is stopped at the effective lines L2 to L4 (when the middle reel 31 is stopped, the symbol “bell” is stopped at the middle stage). The stop position of the reel 31 is determined as follows.

On the other hand, when the pressing order of the stop switch 42 is other than “left / right / middle”, the combination of symbols corresponding to the small role 2 is stopped on the effective line L1 (when the middle reel 31 is stopped, the symbol “bell” is displayed on the upper stage). The stop position of the reel 31 is determined so as to stop.
In the above case, the combination of symbols corresponding to the control combination 2 does not stop on the active line.

  The small combination 2 overlapping winning table C is used when the winning flag 63a of the small combination 2 and the control combination 3 is ON (when the small combination 2 + control combination 3 is selected), and within the range of stop control of the reel 31, When the pressing order of the switch 42 is “middle left / right” or “middle right / left” (that is, when the first operated stop switch 42 is the middle stop switch 42), a combination of symbols corresponding to the small role 2 is selected. The stop position of the reel 31 is determined so as to stop at the effective lines L2 to L4 (when the middle reel 31 stops, the symbol “bell” is stopped at the middle stage).

On the other hand, when the pressing order of the stop switch 42 is other than “middle left / right” or “middle right / left” (that is, when the first operated stop switch 42 is the left or right stop switch 42), The stop position of the reel 31 is determined so that the symbol combination corresponding to 2 stops on the effective line L1 (when the middle reel 31 stops, the symbol “bell” is stopped at the upper stage).
In the above case, the combination of symbols corresponding to the control combination 3 does not stop on the active line.

  The small combination 2 overlapping winning table D is used when the winning flag 63a of the small combination 2, the control combination 1 and the control combination 2 is ON (when the small combination 2 + control combination 1 + control combination 2 is selected) and the reel 31 is stopped. Within the control range, when the pressing order of the stop switch 42 is “middle right / left”, the combination of symbols corresponding to the small part 2 is stopped at the effective lines L2 to L4 (when the middle reel 31 is stopped, “ The stop position of the reel 31 is determined so that the “bell” symbol is stopped).

On the other hand, when the pressing order of the stop switch 42 is other than “Right / Left / Middle”, the combination of symbols corresponding to the small role 2 is stopped on the effective line L1 (when the middle reel 31 is stopped, the symbol “Bell” is displayed at the upper stage). The stop position of the reel 31 is determined so as to stop.
In the above case, the combination of symbols corresponding to the control combination 1 and the control combination 2 does not stop on the effective line.

  The small combination 2 overlapping winning table E is used when the winning flag 63a of the small combination 2, the control combination 1 and the control combination 3 is ON (when the small combination 2 + control combination 1 + control combination 3 is selected) and the reel 31 is stopped. Within the control range, when the pressing order of the stop switch 42 is “right middle left”, the combination of symbols corresponding to the small part 2 is stopped at the effective lines L2 to L4 (in the middle stage when the middle reel 31 is stopped). The stop position of the reel 31 is determined so that the “bell” symbol is stopped).

On the other hand, when the pressing order of the stop switch 42 is other than “right middle left”, the combination of symbols corresponding to the small role 2 is stopped on the effective line L1 (when the middle reel 31 is stopped, “bell” is The stop position of the reel 31 is determined so that the symbol is stopped.
In the above case, the combination of symbols corresponding to the control combination 1 and the control combination 3 does not stop on the effective line.

  The small role 3 table is a stop position determination table 65 that is used when only the winning flag 63a of the small role 3 is on. The combination of symbols corresponding to the small role 3 is within the range of stop control of the reel 31. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to the combinations other than the small combination 3 is not stopped on the effective line while being stopped on the effective line.

The replay 1 table is used when the winning flag 63a of the replay 1 (only) is on, and within the range of the stop control of the reel 31, the combination of symbols corresponding to the replay 1 is stopped on the effective line, and the replay is performed. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to a combination other than 1 is not stopped on the effective line.
The replay 3 table is the same as the replay 1 table. The replay 3 table corresponds to the one obtained by replacing “replay 1” with “replay 3” in the above replay 1 table.

  The replay 1 / replay 2 overlap winning table A is used when the replay 1 and replay 2 overlap winning A is performed, and within the range of the stop control of the reel 31, the pressing order of the stop switch 42 is “left middle right”. If it is, the symbol combination corresponding to the replay 2 is stopped on the effective line, and when the pressing order of the stop switch 42 is other than the above, the symbol combination corresponding to the replay 1 is stopped on the effective line. 31 stop positions are defined.

  The replay 1 / replay 2 overlapping winning table B is used when the replay 1 and replay 2 overlapping winning B are performed, and the stop switch 42 is pressed in the “left / right middle” within the range of the stop control of the reel 31. In some cases, the symbol combination corresponding to the replay 2 is stopped on the effective line, and when the pressing order of the stop switch 42 is other than the above, the symbol combination corresponding to the replay 1 is stopped on the effective line. The stop position is determined.

  Further, the replay 1 / replay 2 overlap winning table C is used when the replay 1 and replay 2 overlap winning C is established, and within the range of the stop control of the reel 31, the pressing order of the stop switch 42 is “middle left and right. ”Or“ middle right / left ”(when the middle stop switch 42 is operated for the first time), the combination of symbols corresponding to the replay 2 is stopped on the effective line, and the pressing order of the stop switch 42 is other than the above. Defines the stop position of the reel 31 so that the combination of symbols corresponding to the replay 1 is stopped on the effective line.

  Further, the replay 1 / replay 2 overlapping winning table D is used when the replay 1 and replay 2 overlapping winning table D is reached, and within the range of the stop control of the reel 31, the pressing order of the stop switch 42 is “right and left”. When it is “medium”, the symbol combination corresponding to the replay 2 is stopped on the effective line, and when the pressing order of the stop switch 42 is other than the above, the symbol combination corresponding to the replay 1 is stopped on the effective line. The stop position of the reel 31 is determined.

  Further, the replay 1 / replay 2 overlap winning table E is used when the replay 1 and replay 2 overlap winning E is established, and within the range of the stop control of the reel 31, the pressing order of the stop switch 42 is “middle right”. When “left”, the symbol combination corresponding to Replay 2 is stopped on the effective line, and when the pressing order of the stop switch 42 is other than the above, the symbol combination corresponding to Replay 1 is stopped on the effective line. The stop position of the reel 31 is determined.

Also, as the stop position determination table 65 used when the replay 1 and the replay 3 are duplicated winnings A to E, a replay 1 / replay 3 overlapping winning table A to a replay 1 / replay 3 overlapping winning table E are provided. Yes.
These replay 1 and replay 3 overlapping winning tables A to replay 1 and replay 3 overlapping winning tables E are respectively “replay 2” and “replay 2 overlapping winning tables E” to “replay 2”. "Is replaced with" Replay 3 ".

The non-winning table is used when all the winning flags 63a are off (that is, when a winning combination in a non-internal game or a special game is not won), and a combination of symbols corresponding to any winning combination becomes an active line. The combination of symbols when the reel 31 is stopped is determined so as not to stop.
Although details are omitted, if a small role or replay is won in an internal game, priority is given to the small role or replay won in the game, and if the small role or replay cannot be won, A stop position determination table 65 is used for controlling to win a special combination that has been carried over.

Next, the relationship between the symbol arrangement of the reels 31 and stop control will be described.
As shown in FIG. 2, in all the reels 31, the “bell” symbols are arranged at intervals within 5 symbols. As a result, the reel control means 64 can always stop the “bell” symbol at a desired position no matter which moment the reel 31 is positioned and the stop switch 42 is operated. Therefore, when the small role 2 is won, the “bell” symbol can be stopped on the upper stage, and the “bell” symbol can be stopped on the middle stage.

  Similarly, as shown in FIG. 2, in all the reels 31, the symbols “RP” are arranged at intervals within 5 symbols. As a result, the reel control means 64 can stop the symbol “RP” on a desired effective line, regardless of which moment the reel 31 is positioned and the stop switch 42 is operated. Therefore, when the replay 1 is won, the reel control means 64 can always stop the combination of symbols corresponding to the replay 1 on the desired effective line.

  Further, with respect to the replay 2 and the replay 3 having the symbols “bell” and “RP”, the reel control means 64 can select the desired effective line regardless of which moment the stop switch 42 is operated when the reel 31 is positioned. The combination of symbols corresponding to Replay 2 and Replay 3 can be stopped.

  Further, when the SB table is used, when the combination of symbols corresponding to SB cannot be stopped on the effective line, the SB stubby can always be stopped on the effective line. For the left reel 31 and the right reel 31, the “bell” symbol can be stopped at a desired effective line, and for the middle reel 31, the “red cherry” or “BAR” symbol can be stopped at a desired effective line. It is because it can be made.

  On the other hand, the symbols of “red 7”, “blue 7”, “watermelon”, “red cherry” of the left reel 31 and “blue cherry” of the right reel 31 are arranged with an interval exceeding 5 symbols. . As a result, when winning the winning combination of BB, RB, SB, small combination 1 and small combination 3, if the stop switch 42 is not operated at the timing when the symbol corresponding to the winning combination stops on the active line, the symbol corresponding to the winning combination The combination of does not stop on the active line.

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

  The payout means 67 determines that the combination of symbols stopped on the active line when the reel 31 is stopped matches the combination of symbols corresponding to any of the combinations by the stop symbol determination unit 66 and the winning combination is won. In addition, a predetermined number of medals are paid out to the player in accordance with the winning combination, or processing such as credit addition is performed. In addition, when the replays 1 to 3 are won, control is performed so that the number of medals inserted in the game (three) is automatically inserted without paying out medals.

Further, when the symbol combination corresponding to the combination is simultaneously stopped on a plurality of effective lines, the payout means 67 controls to pay out the number obtained by multiplying the number of effective lines.
Here, all the combinations of symbols corresponding to the small combination 3, the small combination 4, and the replay 1 to the replay 3 do not stop at a plurality of effective lines at the same time.

  On the other hand, when the small role 1 stops at one effective line L2 or L4 (when the symbol of “red cherry” stops at the middle or lower level when the left reel 31 stops) and two effective lines And when stopping at L1 and L3 at the same time (when the symbol of “red cherry” stops at the upper stage when the left reel 31 is stopped). In the former case, the payout number is 1 × 1 (effective line number) = 1, whereas in the latter case, the payout number is 1 × 2 (effective line number) = 2. .

  In addition, the small role 2 is simultaneously applied to the three effective lines L2, L3, and L4 when stopped on one effective line L1 (when the “bell” symbol is stopped on the upper stage when the middle reel 31 is stopped). And when it stops (when the “bell” symbol stops in the middle when the middle reel 31 stops). In the former case, the number of payouts is 3 × 1 (effective line number) = 3. In the latter case, the payout number is 3 × 3 (effective line number) = 9. .

The special game control means 68 controls the start of the special game, the progress of the game during the special game, and the end of the special game.
During a normal game, when a combination of symbols corresponding to BB (BB1 or BB2), RB (RB1 or RB2) or SB stops on the active line, BB, RB or SB wins respectively, and special game control means 68 Controls to start the BB game, the RB game, or the SB game from the next game, respectively.
In the BB game, the RB game, or the SB game, the lottery of the combination is performed using the above-described combination lottery table 62F. Thereby, in the special game, the winning probability of the small role 2 is increased.

In the present embodiment, the BB game end condition is set such that the number of medals paid out during the BB game is 397 or more. In addition, as an RB termination condition, the number of medals paid out during the RB game is set to be 205 or more.
For this reason, in the BB game or RB game, the special game control means 68 continues to count the number of medals paid out, and when it is determined that the count value has reached the above value, the BB game or RB game is terminated with the game. To control.

  Further, only one game is played in the SB game. Therefore, when the SB wins, the SB game is played in the next game (one game), and the SB game is controlled to end with the game regardless of whether or not the winning combination is made.

The gaming state control means 69 controls transition between gaming states. FIG. 8 is a diagram for explaining the transition of the gaming state.
First, in a non-internal game (non-RT game, RT1 game, RT2 game or RT3 game), BB or RB is won, and when BB or RB won in that game wins, the game shifts to BB game or RB game. . In addition, when BB or RB is won and the BB or RB won in the game does not win, the game shifts to an internal game. The inside game is continued until the winning BB or RB wins.

  If the SB is won in the non-inside of the normal game and the SB wins in the game, the SB game is executed in the next game, but when the SB game ends, the game state before the transition to the SB game is resumed. Control to return.

When the BB game ends, the game shifts to the RT1 game. Also, when the RB game ends, the process shifts to the RT3 game.
The RT1 game is continued until the SB Koboshi stops. When the SB Koboshi stops, control is performed to shift to a non-RT game.

  Note that, as will be described later, the RT1 game is always an AT game, and a stop switch 42 for stopping the selected small combination 2 on the three effective lines L2 to L4 when the small combination 2 and the control combination are won simultaneously. The order of pressing is notified.

  In addition, when the SB is won in the RT1 game, the probability that the SB wins is low. Therefore, at the time of winning the SB, the SB Koboshi is normally stopped. Thereby, it shifts from RT1 game to non-RT game. Note that the RT1 game is continued unless the SB Koboshi stops in the RT1 game.

Non-RT games may be AT games or non-AT games.
In non-RT games, the game continues until Replay 1 or Replay 2 wins. At the time of replay 1 winning, control is performed so as to shift to the RT3 game. On the other hand, when replay 2 is won, control is performed so as to shift to the RT2 game.

In a non-RT game, there may be a duplicate winning of Replay 1 and Replay 2 and a overlapping winning of Replay 1 and Replay 3. During AT game, the player is notified of the pressing order of the stop switch 42 for winning the replay 2 or the replay 3. Therefore, during an AT game, Replay 1 will not win unless the player makes a mistake in the pushing order. In addition, when the replay 1 and the replay 2 are overlapped, the replay 2 can be won by following the notified pressing order, and the game can be shifted to the RT2 game.
On the other hand, in a non-RT game, the replay 1 may win a prize because the push order is not notified during a non-AT game.

When transitioning to the RT2 game, 20 games are continued. Then, after the 20th game is over, the game returns to the non-RT game again. It should be noted that in the RT2 game, there is no transition of the game state when the SB Koboshi is stopped or even if any replay wins.
Further, when the game shifts to the RT3 game, 38 games are continued. Then, after the 38th game is over, the game returns to the non-RT game again. Note that in the RT3 game, as in the RT2 game, the game state does not change even if the SB Koboshi is stopped or any replay is won.

Although the payout rate will be described later, as shown in FIG. 8, in the AT game of the non-RT game and in the RT2 game, the payout rate exceeds 1 (100%), which is advantageous to the player.
On the other hand, in the RT3 game, the payout rate is less than 1, which is a disadvantageous game for the player.
Further, during the AT game, it is possible to go back and forth between the non-RT game and the RT2 game, so that it is possible to wait for the special role winning while increasing the medals.

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.
The effect control means 70 selects an effect pattern for each game based on the lottery result of the combination by the combination lottery means 61. Particularly in this embodiment, a plurality of types of effect patterns are provided in advance. Then, the effect control means 70 selects one effect pattern by lottery using software random numbers after the role lottery means 61 has been drawn at the start of the game.

In addition, a plurality of types of production patterns are provided according to the winning combination. For example, a plurality of types of effect patterns are provided for each special role winning, small role winning, replay winning, non-winning, and the like.
As for the production pattern, as to the progress of the game, at what timing (when the start switch 41 is operated, when each stop switch 42 is operated, etc.) what kind of production is output (how the lamp 21 is lit) And what kind of sound is output from the speaker 22, what kind of image is displayed on the image display device 23, etc.).
Then, the effect control means 70 controls to output an effect from the effect output device at a predetermined timing according to the selected effect pattern.

In addition, the effect control means 70 includes AT game control means 71.
Here, “AT (Assist Time) game (notification game)” refers to a specific role (special role, small role or replay) having a case where a winning is made and a case where a winning is not made depending on the pressing order or operation timing of the stop switch 42. In addition, during a normal game, a specific role can be won only by chance, but during an AT game, the stop switch 42 for pressing the specific role or the operation timing (on the active line) When the player operates the stop switch 42 in accordance with the notification, the player can increase the winning rate of the specific combination (can surely win the specific combination). Say.
A game that does not notify the pushing order as described above is referred to as a “non-AT game”.

And in this embodiment, the small role 2, Replay 1-Replay 3 are provided as a role equivalent to the said specific role. At the time of overlapping winning of the small combination 2 and the control combination, there are cases where the payout number of the small combination 2 becomes 3 and 9 according to the pressing order of the stop switch 42.
In the present embodiment, when the winning combination of the small combination 2 and the control combination is won during the AT game (RT1 game, non-RT game, and RT2 game), the payout number of the small combination 2 is nine. The player is notified of the pressing order of the stop switch 42.

In addition, when replay 1 and replay 2 are overlapped, there are cases where replay 1 wins and replay 2 wins depending on the pressing order of stop switch 42.
In the present embodiment, when the replay 1 and the replay 2 are repeatedly won during the AT game (non-RT game), the player is determined to push the stop switch 42 in order to win the replay 2 (do not win the replay 1). Notify them.

The same applies to the case where the replay 1 and the replay 3 are duplicated.
In this embodiment, when the replay 1 and the replay 3 are won in duplicate during the AT game (non-RT game), the player is given the order of pushing the stop switch 42 to win the replay 3 (do not win the replay 1). Inform.
Note that as a method of notifying the pressing order of the stop switch 42, for example, when the small combination 2 and the control combination 1 are won simultaneously, “Please operate the stop switch 42 in the order of left → middle → right” is displayed. 23 displays an image. Furthermore, you may make it output an audio | voice from the speaker 22 with the said content.

Further, the AT game control means 71 includes the following AT game number storage means 71a, AT game number determination means 71b, and storage number determination means 71c.
The AT game number storage means 71a is configured to add a predetermined number or a number determined by lottery to the number stored so far when the condition for storing the number of executions of AT games is satisfied. In the case of storing the number of times of storage, for example, a 16-bit counter is used, and it is possible to store (store) up to “65535”.
Here, “the number of executions of the AT game” indicates the number of transitions from the non-RT game to the RT2 game in the present embodiment.

In the present embodiment, as the number of times of storage, there are a) a case where a predetermined number is added and b) a case where the number determined by lottery is added.
And as an opportunity to add the number of storage,
(1) At the time of winning in the storage lottery performed every game (2) At the time of winning BB or RB (3) During the BB game or when RB game is not won (4) When freezing occurs (5) Internal game Can be mentioned.

First, except for special games, every game (regardless of the type of winning combination), a lottery (lottery using software random numbers) that wins at 1/150 is performed, and when winning in this lottery, Add “1” to the number of storages.
Secondly, in a game won for BB or RB, “1” is unconditionally added as the number of times of storage. Thirdly, “3” is unconditionally added as the number of times of storage when a winning combination is not won during a BB game or an RB game.

  Fourth, when freeze occurs, “3” is added unconditionally as the number of times of storage. Here, the “freeze” is selected by the game control means 50 on the condition that the game is a winning game of BB or RB or an internal game, and a predetermined time (for example, after the start switch 41 is operated) This is an operation (effect) for starting the rotation of the reel 31 after a predetermined time has elapsed without rotating the reel 31 for 5 seconds. That is, when freeze is selected, the reel control means 64 controls to start the rotation of the reel 31 after a predetermined time elapses after the start switch 41 is operated in accordance with the determined freeze operation.

  When freeze is selected, information to that effect is transmitted to the effect control means 70. The effect control means 70 selects an effect pattern dedicated for freezing, and controls to output an effect meaning that the special role is won during the freeze.

  Fifth, in an internal game, when each game, the start switch 41 is operated, whether to store by lottery is determined using a software random number, and when it is determined to store, Add “1” to the number of storages. In the internal game, the lottery is performed regardless of the winning combination.

  FIG. 9 is a diagram showing the winning probability of the storage lottery in the internal game. As shown in FIG. 9, the winning probability is determined to be different for each set value. For example, in setting 1, it is determined to win with a probability of 1 / 2.0. That is, in the game in the inside, a lottery for winning with a probability of 1 / 2.0 is performed for each game, and when the lottery is won, “1” is added to the number of times of storage. In this embodiment, the added value when winning in this lottery is “1”, but the added value may be determined by lottery.

  From FIG. 9, the lower the set value, the higher the winning probability is set (so that it can be easily added). In particular, in setting 6, since the winning is made only with a probability of 1/100, it is rare that the number of times of storage increases in internal games. For this reason, the higher the setting is, the longer the internal medium game is extended (even if the special role is not intentionally won), the player has no real benefit. In particular, the settings 5 and 6 are designed such that the smaller the number of games in the internal game, the higher the total payout rate including the BB game and the AT game.

Specifically, for example, in the case of setting 5, when the game is shifted to the internal middle game, the number of times of storage is not added by “1” unless the average of 30 internal games are consumed. In other words, an average of 30 games are required to add “1” to the number of times of storage.
Here, although the details will be described later, the expected value of the difference number of one game in the internal middle game is “−1.95 (sheets)”.

Therefore, when 30 games are consumed in the game inside,
−1.95 × 30 = −58.5.
On the other hand, the expected value of the difference number of one game in the AT game of RT2 game is “+0.62 (sheets)”.
Therefore, when 20 games are consumed in RT2 games (AT games),
+ 0.62 × 20 = + 12.4.

  Therefore, it is more disadvantageous for the player to spend 30 games in the internal game than to increase the RT2 game (AT game) once (20 games). Therefore, in the setting 5, even if the game in the inside is extended (even if the special role is not intentionally won), the player has no profit. The same applies to setting 6. In particular, in setting 6, since the number of times of storage is incremented by “1” only with a probability of 1/100 in an internal game, there is no profit even if the internal game is extended beyond setting 5.

  The AT game number determination means 71b determines the number of times of AT game execution (release) as a predetermined number of times or the number of times determined by lottery when the conditions for executing AT games are satisfied, and the above-mentioned number of AT games. The determined number of executions is subtracted from the number of times stored in the storage means 71a. Although details will be described later, the number of executions of the AT game first determined here is a provisional value.

In the present embodiment, the AT game is executed after the end of the BB game. For this reason, when BB is won, it is determined that the condition for executing the AT game is satisfied.
Then, at the time of winning the BB, the number of executions of the AT game is determined by lottery based on the type of BB won, the set value, and the number of stored BBs.
The lottery of the number of executions may be performed at any time during BB winning, BB inside game, BB winning, BB game, BB game end, RT1 game, or non-RT game. In the embodiment, at the end of the BB game (at the end of the medal payout in the last game of the BB game), the lottery is performed using a software random number.

  FIG. 10 is a diagram showing the relationship between the type of BB, the set value, and the number of executions of the AT game. As described above, the BB has BB1 and BB2, but it is set so that the expected value of the number of executions of the AT game is higher when BB2 is won than when BB1 is won. Further, the higher the set value (the higher the set value), the higher the expected number of AT game executions. In the present embodiment, one of AT game execution times is selected from “1”, “3”, “5”, “7”, “10”, “15”, and “20”.

  In FIG. 10, for example, when BB2 is won and the setting value is setting 2, the number of executions is determined to be “1” with a probability of 1%, and the number of executions is determined to be “3” with a probability of 4%. The execution count is determined as “5” with a probability of 10%, the execution count is determined as “7” with a probability of 30%, the execution count is determined as “10” with a probability of 30%, and the probability of 20%. The number of executions is determined to be “15”, and the number of executions is determined to be “20” with a probability of 5%.

  Note that the number of executions of the AT game may be uniquely determined according to the type of BB and the set value without using a lottery. For example, it is possible to provide a data table that defines the number of executions of AT games corresponding to the type of BB and the set value.

The AT game control means 71 refers to the AT game storage number when the number of AT game executions is determined by the lottery, and determines the final AT game execution number (the number of AT game executions). To confirm).
Here, when “the determined number of AT game executions ≦ the number of AT game storages”, the number of executions determined by the AT game number determination means 71b is determined as the final number of executions.
On the other hand, when “the determined number of AT game executions> the number of AT game storages”, control is performed so that “the number of AT game executions = the number of AT game storages” is processed. That is, control is performed so that the maximum value of the number of AT games stored is determined as the final number of executions.

Then, when “the determined number of AT game executions ≦ the number of AT game storages”, a value obtained by subtracting the determined number of AT game executions from the number of AT game storages at that time is a new value. Control is performed to store (update) the number of AT games stored. For example, when the storage number is “40” and the execution count is determined to be “15”, the new storage number is set to “25”.
On the other hand, when “the number of AT game executions = the number of AT game storages”, the new storage number is set to “0”.

  In this embodiment, when BB or RB is won, “1” is unconditionally added to the number of storages. Therefore, when the number of AT game executions is determined, the number of storages is “0”. There is no. Also, as shown in FIG. 10, since the minimum value of the number of executions of AT games in this embodiment is “1”, the number of executions is not determined to be “0”.

  As described above, the lower the number of AT games stored, the easier it is stored, and the higher the number of AT games stored, the less likely it is to store. On the other hand, the number of executions (releases) of AT games is smaller as the setting is lower and increases as the setting is higher.

  When “the number of times of AT game execution” is determined (determined), the value is set as an initial value. For example, when the number of executions is determined to be “15”, the initial value of the number of executions is set to “15” and the value of the number of executions is set to “−” every time the RT2 game (20 games) is consumed once. Continue to subtract (count) by 1 ”. In the present embodiment, when the replay 2 wins in the non-RT game and shifts to the RT2 game, “1” is subtracted from the value so far. Note that the subtraction may be performed during RT2 game or when 20 games are consumed in RT2 game (when transitioning from RT2 game to non-RT game). When the number of executions is “0” and the game is shifted to the non-RT game, the AT game control means 71 controls the game state to be set to the non-AT game thereafter.

  Therefore, in this non-RT game and non-AT game, when the replay 1 and replay 2 are won simultaneously, or when the replay 1 and replay 3 are won simultaneously, the push order of the stop switch 42 is not notified. There is. When Replay 1 wins in a non-RT game, the game moves to RT3 game. On the other hand, when Replay 2 wins, it shifts to RT2 game. However, the RT2 game in this case is a non-AT game.

Further, as shown in FIG. 1, the effect control unit 70 includes a symbol notification unit 72. The symbol notifying means 72 is for notifying a player of a combination of symbols corresponding to the selected special combination after winning the special combination (BB1, BB2, RB1, or RB2) by the combination lottery means 61.
Furthermore, for each set value, a lower limit value (threshold value) of the number to be stored in the AT game number storage means 71a is determined in advance for a specific number of games. FIG. 11 is a diagram showing this lower limit value. In the present embodiment, a lower limit value of the number of storages in the number of 3000 games is determined in advance. For example, in setting 1, the lower limit value of the storage number in 3000 games is set to “25”.

Then, the storage number determination means 71c determines the number stored in the AT game frequency storage means 71a during the past 3000 games excluding special games, and determines whether the storage number has reached the lower limit value. . Note that whether or not the lower limit value is reached may be estimated according to a certain rule.
When it is determined that the lower limit has not been reached, the symbol notification means 72 plays the number of games (from the game won for the special role until the player is notified of the combination of symbols corresponding to the selected special role) Hereinafter, control is performed so that the number of non-notification games is set long.

  For example, when BB1 is won in the game, the storage number determination means 71c determines whether or not the storage number in the past 3000 games from the game is equal to or less than the lower limit value. Then, when it is determined that the number is less than the lower limit, for example, in the case of setting 1, if the number of times of storage in the past 3000 games is “21”, the number of times of non-notification game is increased in order to increase the number of times of storage in internal games Is set to “7”. On the other hand, when it is determined that the lower limit value is exceeded, the number of non-notification games is set to “4”. By controlling in this way, when the number of storage is smaller than the planned number, the number of games in the internal middle game is easily increased, and an effort is made to increase the number of storage.

  Since there are four combinations of symbols corresponding to the special combination as shown in FIG. 4, it is rare that the special combination wins immediately after winning the special combination. It takes a certain number of games before the player knows that the special role is won from the game won for the special role, and even if the player knows that the special role is won, 4 This is because the special role cannot be won without knowing which special role is elected among the special roles of the type. Even if the player guesses the symbol related to the winning special role and the player looks forward to it, the probability of not winning is higher than the probability of winning.

Furthermore, lotteries for small roles and replays are also drawn in internal games, and when winning a small role or replay, winning of the selected small role or replay is given priority. (However, as described above, whether or not the game is stored is determined by lottery). Therefore, the average number of games in the inside is 5 to 6 games.
From the above, a player who cannot immediately recognize the special role winning, or a player who cannot know what kind of special role has been won and cannot win immediately because the aim is not accurate ( That is, in the hall with many beginners), the number of storage tends to increase.
On the other hand, there are many players who can immediately recognize the winning of a special role, and players who can win immediately if they know what kind of special role they are winning (ie, advanced players) In the hall, the number of storage does not increase so much.
Therefore, it is possible to automatically balance the balls in the slot machine 10 according to the level of the player.

In addition, P (for example, 300) game in setting 1 → P game in setting 2 → P game in setting 3 → P game in setting 4 → P game in setting 5 → Next, when game is played in setting 6 Let X1 be the expected value of the ball rate (or the number of times an AT game has been executed).
On the other hand, when the expected value of the payout rate (or the number of executions of the AT game) is set to X2 after the P game is played in the setting 1 and then the game is played in the setting 6 next,
X2> X1
Is set to

  In particular, in the present embodiment, the settings 1 to 3 are set so that “the expected value of the number of AT games stored (at a predetermined number of games)> the expected value of the number of executions of AT games (at a predetermined number of games)”. ing. In other words, the set value is set so that the expected number of pools at a predetermined number of games exceeds the expected value of the number of runs (the number of pools increases as the number of games increases).

  Further, in the settings 4 to 6, the setting is such that “the expected value of the number of AT games stored (in a predetermined number of games) <the expected value of the number of AT games executed (in a predetermined number of games)”. In other words, the set value is set so that the expected number of executions in a predetermined number of games exceeds the expected number of pools (the number of pools decreases as the number of games increases).

It should be noted that “the expected value of the number of AT game storages (at a predetermined number of games) −the expected value of the number of AT game executions = Y”, Y = Y1 in setting 1, Y = Y2 in setting 2,... When Y = Y6 in setting 6,
Y1 ≧ Y2 ≧ ・ ・ ・ ≧ Y6
It is set to become.

Therefore, from setting 1 to setting 5 in sequence, after setting the predetermined number of games in setting 1 rather than the amount of play in setting value 6 after performing the predetermined number of games for one setting value, the setting is suddenly performed. The ball-out rate when 6 is set is higher. This is because when the setting 6 is made after a large number of storages are stored in the setting 1, a large number of storages are executed (released).
On the other hand, if the setting value is increased sequentially from setting 1, the number of AT game executions gradually increases as the setting value increases. For example, setting 6 is made after setting 4 and setting 5. The payout rate is lower than when setting 1 is suddenly changed from setting 1.

  The same applies to other patterns. For example, when setting 1 → setting 2 → setting 5 is set, the number of executions of the AT game is increased as compared with setting 1 → setting 4 → setting 5.

Next, the payout rate will be described.
First, “the expected value of the number of medals to be paid out per game” means a winning probability of a combination in one game × the number of payouts. The expected value of the “difference number” per game means the expected value of the increase / decrease number of medals per game, and can be expressed as “expected value of payout number−insertion number”. When the expected value of the difference number is a positive value, it is a gaming state in which medals increase as the game progresses, and when it is a negative value, the medals decrease as the game progresses. It is a game state to go.

  Further, the “delay rate” can be expressed as “expected value of payout number / insertion number”, and when the value exceeds 1, it is a gaming state in which medals increase as the game progresses. When the value is less than 1, the game state is such that medals decrease as the game progresses.

Also, during AT games, when the small combination 2 and the control combination are won simultaneously, nine medals can be paid out. On the other hand, during a non-AT game, 9 pieces are paid out with a probability of 1/5, but 3 pieces are paid out with a probability of 4/5.
Here, it is assumed that at the time of winning the small role 1, one payout is always received, and at the time when the small role 3 is winning, 6 payouts are always received. Also, assuming that there are three medals paid out at the time of winning Replay 1 to Replay 3, the expected value of the number of medals paid out per game during RT1 game (and AT game) is:
1 × 1/100 + 9 × 1/100 + 9 × 1/10 + 6 × 1/50 + 3 × 1 / 7.3
≒ 1.53 (sheets)
It becomes.

Therefore, the expected value of the difference is
1.53-3
= -1.47 (sheets)
It becomes.
Also, the payout rate is
1.47 / 3
= 0.49
It becomes.

In RT3 games (non-AT games) and internal games,
1 × 1/100 + 9 × 1/100 + 9 × 1/10 × 1/5 + 3 × 1/10 × 4/5 + 6 × 1/50 + 3 × 1 / 7.3
≒ 1.05 (sheets)
It becomes.
Therefore, the expected value of the difference is
1.05-3
= -1.95 (sheets)
It becomes.
Also, the payout rate is
1.05 / 3
= 0.35
It becomes.

Furthermore, during RT2 games and AT games,
1 × 1/100 + 9 × 1/100 + 9 × 1/10 + 6 × 1/50 + 3 × 1 / 1.2
= 3.62 (sheets)
It becomes.
Therefore, the expected value of the difference is
3.62-3
= +0.62 (sheets)
It becomes.
Also, the payout rate is
3.62 / 3
≒ 1.21
It becomes.

In contrast, during RT2 games and non-AT games,
1 × 1/100 + 9 × 1/100 + 9 × 1/10 × 1/5 + 3 × 1/10 × 4/5 + 6 × 1/50 + 3 × 1 / 1.2
= 3.14 (sheets)
It becomes.
Therefore, the expected value of the difference is
3.14-3
= +0.14 (sheets)
It becomes.
Also, the payout rate is
3.14 / 3
≒ 1.05
It becomes.

Also, during non-RT games and AT games,
1 × 1/100 + 9 × 1/100 + 9 × 1/10 + 6 × 1/50 + 3 × 1/5 + 3 × 1/2
= 3.22 (sheets)
It becomes.
Therefore, the expected value of the difference is
3.22-3
= +0.22 (sheets)
It becomes.
Also, the payout rate is
3.22 / 3
≒ 1.08
It becomes.

In contrast, during non-RT games and non-AT games,
1 × 1/100 + 9 × 1/100 + 9 × 1/10 × 1/5 + 3 × 1/10 × 4/5 + 6 × 1/50 + 3 × 1/5 + 3 × 1/2
= 2.74 (sheets)
It becomes.
Therefore, the expected value of the difference is
2.74-3
= -0.26 (sheets)
It becomes.
Also, the payout rate is
2.74 / 3
≒ 0.91
It becomes.

As a result, during the AT game of the non-RT game and during the RT2 game (non-AT game and AT game), the game state is such that medals increase as the game progresses (a game state advantageous to the player).
On the other hand, other than the above gaming state in the normal game, the game state is such that medals decrease as the game progresses (a gaming state that is disadvantageous to the player). However, during a non-AT game of a non-RT game, the game state is such that the number of medals owned is almost maintained.

The expected value of the number of medals paid out per game during a special game is
1 × 1/100 + 9 × 1 / 1.05 + 6 × 1/50
≒ 8.70 (sheets)
It becomes.
Therefore, the expected value of the difference is
8.70-3
= +5.70 (sheets)
It becomes.
Also, the payout rate is
5.70 / 3
= 1.9
It becomes.
Therefore, the special game is a game state in which medals increase rapidly with the progress of the game, and is a game state advantageous to the player.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to embodiment mentioned above, The following various deformation | transformation are possible.
(1) The lottery of the number of AT games stored is not necessarily limited to the one shown in the embodiment, and may be performed at any timing during the game (when any condition is satisfied).

  (2) Similarly, the lottery of the number of executions of AT games is not limited to that shown in the above embodiment, but may be performed for non-RT games, RT1 games, RT2 games, RT3 games, and the like. Further, the lottery may be a lottery in which each game is won with a predetermined probability (for example, 1/400), or with a predetermined probability (for example, 1/3) at the time of winning or winning a specific role (for example, small role 1). A lottery to win may be performed. Further, when a specific combination is won or won, an AT game may be executed unconditionally (without performing a lottery). In this case, the number of executions of the AT game may be set uniformly or may be determined by lottery.
