Description

This disclosure relates to a gaming machine.

As shown in Patent Document 1, some slot machines allow a game to proceed depending on either a normal gaming state or an advantageous gaming state that is more advantageous to the player than the normal gaming state. Examples of the advantageous gaming state include a gaming mode in which a player can obtain benefits related to the payout of medals (game media) such as AT, ART, and bonus.

Japanese Patent No. 6572457

If the push order is won in the advantageous game state, the player receives a medal (game medium) by pressing the stop switch according to the announced correct push order. This operation is repeated during the advantageous gaming state, and the number of medals in the player's hand increases.

However, continuing to perform the operation results in repeating monotonous work. Therefore, the player may eventually become exhausted and make an operation error, which may adversely affect the increase in the number of medals at hand.

An object of the present disclosure is to provide a game property in which a game is not a monotonous task.

A stop switch that accepts operations to stop the rotation of the plurality of rotary reels,
An internal lottery unit that performs an internal lottery based on the operation of the start switch and determines whether or not at least one of the plurality of roles has been won.
A rotary reel control unit that controls the rotation of a plurality of the rotary reels based on the operation of each of the start switch and the stop switch.
The normal gaming state in which the special role among the plurality of the above-mentioned roles is not won and the prize is not won, the internal middle game state in which the special role is won but the prize is carried over, and immediately after the winning of the special role is won. It is equipped with a game state control unit that controls switching between a special role implementation state to be started and a game state including.
The plurality of the above-mentioned combinations include a first special combination and a second special combination included in the above-mentioned special combination, and a predetermined combination in which a prize is won and the number of game media to be paid out is paid out regardless of the operation procedure of the plurality of the stop switches. ,
The internal middle gaming state transitions between the first mode in which the first special combination is hit during the normal gaming state and the second special combination in which the second special combination is hit during the normal gaming state. Including at least a second mode that is
Since the payout number at the time of the predetermined winning combination in the second mode is larger than the payout number at the time of the predetermined winning combination in the first mode, the expected value of acquisition of the gaming medium in the second mode is the above. It is a gaming machine characterized by being larger than the first mode.

Further, in the first aspect,
The winning probability of the first special combination in the first mode can be different from the winning probability of the second special combination in the second mode.

Further, in the first aspect,
The winning probability of the first special combination in the first mode can be lower than the winning probability of the second special combination in the second mode.

Further, in the first aspect,

Further, in the first aspect,
The special role further includes a fourth special role.
The internal middle gaming state further includes a fourth mode, which is transitioned by the second special combination being hit during the normal gaming state.
The number of payouts at the time of winning the predetermined combination in the fourth mode is larger than the number of payouts at the time of winning the predetermined combination in the first mode, and the winning of the fourth special combination in the fourth mode is achieved. Since the difficulty is higher than the difficulty of winning the second special role in the second mode, the expected acquisition value of the game medium in the fourth mode is the first mode and the second mode. Can be larger than the mode.

There is at least a second mode in which the game medium can be acquired without being aware of the operation procedure of the stop switch, and a first mode in which the acquisition of the game medium cannot be expected. It depends on whether the role is won. Therefore, the game is unlikely to be a monotonous task, and an interesting game is developed.

As shown in FIG. 2, the slot machine 1 includes a rotary reel unit 2, a control unit 6, a RAM clear button 71, and a setting change button 72. The rotary reel unit 2, the control unit 6, the RAM clear button 71, and the setting change button 72 are arranged inside the housing 10 together with a power supply device (not shown) for turning on and off the main power supply of the slot machine 1. ..

As shown in FIGS. 1 and 2, the rotary reel unit 2 includes four rotary reels 20a, 20b, 20c, 20d and four stepping motors 21a, 21b, 21c, 21d. The rotary reel unit 2 is arranged inside the housing 10 corresponding to the position of the reel window 200. As shown in FIG. 3, a plurality of symbols are arranged on each of the rotary reels 20a, 20b, 20c, and 20d at intervals along the circumferential direction of the reels 20a, 20b, 20c, and 20d. The stepping motors 21a, 21b, 21c, 21d are provided corresponding to the respective rotary reels 20a, 20b, 20c, 20d, and drive the corresponding rotary reels 20a, 20b, 20c, 20d.

The stepping motors 21a, 21b, 21c, 21d are the stop switches 40a, which are operated within 190 msec after the stop switches 40a, 40b, 40c, 40d are operated while the rotary reels 20a, 20b, 20c, 20d are rotating. The rotation of the rotary reels 20a, 20b, 20c, 20d corresponding to the 40b, 40c, 40d is stopped. The stepping motors 21a, 21b, 21c, 21d make one rotation in 504 steps. As a result, the rotary reels 20a, 20b, 20c, and 20d rotate at a speed of 80 rotations / minute. That is, the steps to be advanced within 190 msec are 127 steps.

The rotation and stop of these rotary reels 20a, 20b, 20c, 20d and stepping motors 21a, 21b, 21c, 21d are controlled by the rotary reel control unit 611 (described later) in the control unit 6.

The set value is a value representing the payout rate indicating the ratio of the total number of medals paid out from the hopper unit 50 to the total number of medals inserted in the slot machine 1. Different ball ejection rates are associated with each of the set values of the plurality of stages in advance. The set value affects the internal lottery. The set value is set by an operator (store staff) different from the player before the store opens.

<Flow of games by players>
The player bets medals on the slot machine 1 using the medals inserted from the insertion slot of the medal insertion unit 41 or the medals stored (credited) by operating the bet switch 42. When a predetermined number of medals are bet on the slot machine 1, the valid line L is activated. After that, the lever 43 can be operated, that is, the game can be started.

FIG. 1 illustrates a case where the middle line is activated as an effective line L when a three-sheet bet (three-sheet bet), which is a MAX BET, is placed. The valid line L is a virtual line for determining the winning of the winning combination.

In the following, not only the roles with payout medals such as bells are aligned on the effective line L, but also the symbols corresponding to RB (regular bonus) and replay are aligned on the effective line L, which is expressed as "winning". do.

One game (one game) in the present embodiment is a series in which a player operates a bet switch 42, a lever 43, and a stop switch 40a, 40b, 40c, 40d to obtain a game result including a medal payout process. It refers to the operation.

Specifically, when the lever 43 is operated (lever on) in a state where the game can be started, an internal lottery for determining the winning combination is performed, and the rotations of the rotating reels 20a, 20b, 20c, and 20d are started. In this state, when any of the stop switches 40a, 40b, 40c, 40d is operated, the rotary reels 20a, 20b, 20c, 20d corresponding to the operated stop switches 40a, 40b, 40c, 40d are stopped. All the rotary reels 20a, 20b, 20c, and 20d are stopped, and a predetermined number of medals are paid out according to the combination (winning) of the symbols aligned (winning) on the effective line L. This ends one game.

The player repeats the above game. The game progresses as the game is repeated, and the display of the liquid crystal screen 3 and the output of the sound from the speaker 102 change according to the progress of the game.

<Structure of control unit>
As shown in FIG. 2, the control unit 6 mainly has a main control unit 61 and a sub control unit 62. The main control unit 61 performs controls for advancing the game, such as internal lottery and control of the rotary reels 20a, 20b, 20c, 20d. The sub control unit 62 controls the effect based on the signal transmitted from the main control unit 61.

Each of the main control unit 61 and the sub control unit 62 is composed of a CPU, RAM, and ROM. The ROMs of the main control unit 61 and the sub control unit 62 each store a program necessary for the progress of the game. The RAM of the main control unit 61 stores game data necessary for game progress. The game data includes not only the current number of games but also data indicating the game state and the mode. Various data related to the effect control are stored in the RAM of the sub control unit 62.

When the CPU reads and executes the program in the ROM, the main control unit 61 has an internal lottery unit 610, a rotary reel control unit 611, a game result determination unit 612, a medium management unit 613, a setting unit 614, and a game state control unit. It functions as a 615 and a reset unit 616. The sub control unit 62 functions as an effect control unit 620 (corresponding to a notification control unit).

-Internal lottery part-
The internal lottery unit 610 performs an internal lottery based on the operation of the lever 43, and determines at least one of the plurality of winning combinations. Specifically, the internal lottery unit 610 determines the game state (described later) when the lever 43 is operated, and selects the internal lottery table based on the determined game state. The internal lottery unit 610 wins a winning combination in any of the winning types based on the selected internal lottery table and the random number when the lever 43 is operated. The internal lottery unit 610 generates an internal lottery result signal based on the result of the internal lottery. The internal lottery result signal is transmitted to the rotary reel control unit 611 and the like.

FIG. 4 is a conceptual diagram of the internal lottery table. In the present embodiment, the winning type (condition device) that may be won by the internal lottery differs depending on the type of the gaming state (normal gaming state, internal medium gaming state, RB execution state). Therefore, the internal lottery table of FIG. 4 shows the winning type for each type of gaming state. In FIG. 4, “◯” indicates that there is a possibility of winning, and “×” indicates that there is no possibility of winning. In addition, although there is "Δ" in FIG. 4, this indicates that it is a special state. The special state will be described later.

The winning types include replays, bells, and RB, which is a first-class special character. Replay is a role that allows the next game to be replayed without betting medals. The bell is a role in which medals are paid out when a prize is won, and there are two types, bell 1 and bell 2. RB is a role involved in switching the types of gaming states, and corresponds to a special role. There are three types of RB, RB1, RB2, and RB3.

In FIG. 4, the replay wins and wins with a certain winning probability (1 / 7.3 in this embodiment) regardless of the game state.

Bell 1 wins and wins with a certain winning probability (1 / 1.9 in this embodiment) regardless of the type of gaming state, but the number of payouts at the time of winning differs depending on the type of gaming state. It is a role. The number of bells 1 to be paid out will be described in detail in <Regarding the game state>.

Bell 2 wins and wins with a certain winning probability (1/50, which is lower than Bell 1 in this embodiment) regardless of the type of gaming state. The number of bells 2 to be paid out at the time of winning is always 15 regardless of the type of gaming state.

Each of RB1, RB2, and RB3 may win with each winning probability only during the normal gaming state. RB1, RB2, and RB3 do not win during the internal middle game state and during the RB execution state (corresponding to the special combination execution state). Even if RB1, RB2, and RB3 are all won during the normal gaming state, the winning is performed during the internal middle gaming state. That is, once any one of RB1, RB2, and RB3 wins during the normal gaming state, RB1, RB2, and RB3 do not win in duplicate during the normal gaming state, and the already won RB1. , RB2 and RB3 flags are carried over.

In this embodiment, when RB1, RB2, and RB3 win, one card combination wins at the same time. Therefore, when the RB1, RB2, and RB3 are won, the one-card combination is given priority and the RB1, RB2, and RB3 are not won at the same time. As a result, if the RB1, RB2, and RB3 are hit during the normal gaming state, the winnings of the RB1, RB2, and RB3 are carried over, and therefore the gaming state is changed from the normal gaming state to the internal middle gaming state.

While RB1, RB2, and RB3 are winning and being implemented, one of Bell 1, Bell 2, Replay, and all the roles will win. All the winning combinations are winning combinations regardless of the pressing order and pressing timing of the stop switches 40a, 40b, 40c, 40d by the player during the implementation of RB1, RB2, RB3.

In such information on the winning type according to FIG. 4, one or more combinations of symbols at the time of winning and a combination corresponding to the combination are set in association with each other. In the present embodiment, there is no combination in which the correct pressing order of the stop switches 40a, 40b, 40c, 40d is defined, and a combination in which the number of payouts differs depending on the pressing order. Therefore, when the bell 1 (corresponding to a predetermined combination) and the bell 2 are hit, a prize is won regardless of the order in which the stop switches 40a, 40b, 40c, and 40d are pressed, and the number of medals to be paid out is paid out. Therefore, in the present embodiment, there is no concept of a game section divided into a normal section and an advantageous section.

Here, the special state represented by “Δ” in FIG. 4 will be described. During the internal game state of each of the RB1, RB2, and RB3, the winning chances (possibility of winning) of the RB1, RB2, and RB3 inside are frequently reached. The number of medals that can be obtained at the time of the prize chance differs depending on whether or not RB1, RB2, and RB3 have won the prize. Winning in the internal middle game state Whether or not RB1, RB2, RB3 that is being carried over (internal middle) wins depends on the type of one-card combination that won the internal middle-game state and whether or not the winning one-card combination wins. It depends on whether.

Specifically, as shown in FIG. 5, in each RB internal medium state, 12 types of 1-card winning combinations are candidates for winning (1-card winning combination A to L).

When one piece combination A to D wins in the internal middle state of RB1, one piece dropout control is activated. Therefore, in a game in which one card combination A to D is won in the internal state of RB1, if one card is successfully dropped, the RB1 can be awarded a prize. In the internal middle state of RB1, it is possible to win one card combination E to L other than the one card combination A to D, but even if any of these roles E to L wins, one card will be missed. Since the control does not work, RB1 does not win the prize in exchange for surely paying out one. Therefore, in the internal medium state of RB1, the single-card combination A to D can be said to be the winning chance combination of RB1.

Similarly, in the RB2 internal medium state, the 1-card combination E to H plays the role of the RB2 winning chance role, and in the RB3 internal medium state, the 1-card combination I to L plays the role of the RB3 winning chance role.

That is, in each RB internal medium state, any one-card combination A to L is a winning candidate, but the role of one-card combination A to L depends on which type of RB1, RB2, RB3 is carrying over the prize. Change. In a game in which a single role (winning chance role) that can win the RB inside is won, if the design corresponding to that one piece role (winning chance role) is aligned on the effective line L, the inside is inside. Instead of not winning the RB, the one-card role (winning chance role) wins, and the winning of the RB inside is continued to be carried over. On the contrary, in the game in which the one-card role (winning chance role) that can win the RB inside is won, the symbols corresponding to the one-card role (winning chance role) are not aligned on the effective line L. If one card is missed (no prize), the RB symbol inside appears on the effective line L, and the RB wins.

With the winning of RB1, RB2, RB3 as an opportunity, the gaming state is changed from the internal middle gaming state to the RB execution state of the winning RB1, RB2, RB3. Therefore, it can be said that RB1, RB2, and RB3 serve as a trigger for shifting the gaming state.

-Rotating reel control unit-
The rotary reel control unit 611 controls the drive of the stepping motors 21a, 21b, 21c, 21d based on the operation of the lever 43 or the stop switches 40a, 40b, 40c, 40d, and the rotary reels 20a, 20b, 20c, Rotation start control for starting the rotation of 20d or rotation stop control for stopping the rotation is performed.

Specifically, when the lever 43 is operated while all the rotations of the rotary reels 20a, 20b, 20c, 20d are stopped, the rotary reel control unit 611 uses the rotary reels 20a, 20b, 20c, 20d. Start all rotations. When the stop switches 40a, 40b, 40c, 40d corresponding to the rotating rotary reels 20a, 20b, 20c, 20d are operated during the rotation of at least one rotary reel 20a, 20b, 20c, 20d, the rotary reel control The unit 611 stops the rotation of the rotary reels 20a, 20b, 20c, 20d corresponding to the operated stop switches 40a, 40b, 40c, 40d.

In the rotation stop control, the rotary reel control unit 611 wins a prize by arranging a combination of symbols corresponding to the winning combination on the effective line L based on the operation of the stop switches 40a, 40b, 40c, 40d. As such, the rotation of the rotary reels 20a, 20b, 20c, 20d can be stopped.

Further, in the rotation stop control, the rotation reel control unit 611 has a winning combination by internal lottery and corresponding rotation reels 20a, 20b, 20c, 20d when each stop switch 40a, 40b, 40c, 40d is operated. Pull-in control or kick-off control is performed according to the position of. The pull-in control is a control for stopping the rotation of the rotary reels 20a, 20b, 20c, and 20d by pulling the symbol corresponding to the winning combination onto the effective line L. The kick-off control is a control for stopping the rotation of the rotary reels 20a, 20b, 20c, and 20d so that the symbols corresponding to the winning combinations are not aligned on the effective line L.

When any one of RB1, RB2, and RB3 is won by the internal lottery, the rotary reel control unit 611 controls to arrange the symbols corresponding to the one-card winning combination and give priority to the winning one-card winning combination. In the state where the inside of the RB is inside due to this one-card winning combination, any one of the one-card winning combination A to L wins. In the game in which any one of the winning combinations A to L is won, the player presses the stop switches 40a, 40b, 40c, and 40d in any pressing order and at any timing.

At this time, when the winning single combination is a winning chance combination for the type of RB inside, the stop switches 40a, 40b, 40c, 40d of the rotary reel control unit 611 are pressed third (that is, the third). 3 Stops), the stop type of the rotary reels 20a, 20b, 20c, 20d is controlled. Then, the rotary reel control unit 611 arranges the reels on the effective line L by pressing the fourth stop switches 40a, 40b, 40c, and 40d, and narrows down the constituent symbol pattern candidates for one piece. At the timing when the stop switches 40a, 40b, 40c, and 40d are actually pressed fourth (that is, at the fourth stop), the rotary reel control unit 611 pulls the narrowed-down single-piece combination symbol onto the effective line L. Control is performed to stop the fourth rotary reels 20a, 20b, 20c, and 20d by pulling in if possible. Therefore, if the constituent symbol of the 1-card combination can be drawn onto the effective line L at the actual timing of the 4th stop, the 1-card combination wins.

On the other hand, although the winning 1-card combination is a winning chance combination, if the composition symbol of the 1-card combination cannot be drawn onto the effective line L due to the actual timing of the 4th stop, the 1-card combination will be dropped. .. At this time, the rotary reel control unit 611 stops the symbols corresponding to the winning carry-over RB1, RB2, RB3 on the effective line L in the fourth rotary reels 20a, 20b, 20c, 20d.

If the winning single combination is not a winning chance combination for the type of RB inside, the rotary reel control unit 611 has an effective line L regardless of the actual pressing timing of the stop switches 40a, 40b, 40c, 40d. Control is performed to stop the rotary reels 20a, 20b, 20c, and 20d so that the constituent symbols of one piece are lined up on the top. Therefore, if it is not a winning chance combination, one winning combination is surely won.

Further, the rotary reel control unit 611 changes the control method of the rotary reels 20a, 20b, 20c, 20d depending on the type of the gaming state when the bell 1 which is a predetermined combination is hit. This will be described in detail in <About the game state>.

-Game result judgment unit-
The game result determination unit 612 determines the game result based on the results of the internal lottery and the rotation stop control of the rotary reels 20a, 20b, 20c, and 20d. The game result means the result of determining whether or not the winning combination has won a prize based on the symbols aligned on the effective line L. Specifically, when the combination of the symbols stopped on the effective line L and the combination of the predetermined predetermined symbols match, the game result determination unit 612 determines that the winning combination has won a prize.

―Media Management Department―
The medium management unit 613 controls the increase / decrease in the number of credits and the medal payout operation by the hopper unit 50.

Specifically, when the medal is bet based on the operation of the player, the medium management unit 613 reduces the number of credits according to the number of bets on the medal, and the medal is credited based on the operation of the player. If so, increase the number of credits.

If a winning combination with a medal payout is won by an internal lottery and the winning combination is won based on the player's operation, the media management unit 613 is based on the number of medals paid out based on the type of winning combination. , Increase the number of credits.

Further, the medium management unit 613 controls the hopper unit 50 based on the game result determined by the game result determination unit 612 or the operation signal output by the operation of the settlement switch 45.

Specifically, the medals obtained by winning the winning combination are first stored as credits. If the number of credits exceeds the upper limit (for example, 50) as a result of storing medals, the medals exceeding the upper limit are paid out from the hopper unit 50. Further, when the settlement switch 45 is operated with one or more stored medals, at least a part of the stored medals is paid out from the hopper unit 50.

-Setting part-
The setting unit 614 sets one of a plurality of set values based on the operation of the store staff. In this operation, the setting change button 72 is used. The set value is stored in the RAM of the main control unit 61.

-Game state control unit-
The game state control unit 615 controls to switch the game state. As shown in FIG. 4, the gaming state of the present embodiment includes a "normal gaming state", an "internal medium gaming state", and an "RB implementation state (corresponding to a special combination implementation state)". Of these, each of the "internal middle game state" and "RB implementation state" includes three states corresponding to the three RBs (RB1, RB2, RB3) already described. Specifically, the "internal medium gaming state" includes "RB1 internal internal state", "RB2 internal internal state", and "RB3 internal medium state", and the "RB implementation state" includes "RB1 implementation state" and "RB". "Implementation status" and "RB3 implementation status" are included.

The game state is always set to one of "normal game state", "internal medium game state", and "RB execution state", and this switching control will be described in detail in <About the game state>.

-Reset part-
The reset unit 616 performs a reset process for resetting the game data described above based on the operation of the store staff. Specifically, the reset unit 616 erases the stored game data by initializing the RAM of the main control unit 61 when the store staff presses the RAM clear button 71 or the setting change button 72. As a result, the current number of games becomes zero, and the current gaming state is set to the default setting of "normal gaming state".

As an example, when the setting change button 72 is pressed when the current gaming state is the "normal gaming state" or the "internal medium gaming state", the gaming state immediately before the button 72 is pressed is inherited. Then, the game starts. When the setting change button 72 is pressed when the current game state is the "RB execution state", the game is started with the current game state set to the "normal game state".

―Direction control unit―
The effect control unit 620 displays an effect image selected from a plurality of types of effect images on the liquid crystal screen 3 based on the progress of the game, and also displays sound effects, BGM, sounds, etc. according to the effect images as speakers. Output from 102.

The effect control unit 620 can make at least one of the liquid crystal screen 3 and the speaker 102 notify what kind of current gaming state is. Examples of this notification mode include the following.
(1) A still image or a moving image corresponding to the type of playing state during the stay is displayed on the liquid crystal screen 3.
(2) The speaker 102 outputs voice and music according to the type of playing state during the stay.
(3) Although the still images and moving images on the liquid crystal screen 3 are common, a color effect corresponding to the type of the gaming state during the stay is displayed as the background of the still images and moving images.

As will be described in detail later, in the present embodiment, there is a mode corresponding to the type of the internal medium gaming state (“RB1 internal medium state”, “RB2 internal medium state”, “RB3 internal medium state”). Therefore, the notification of what kind of current gaming state is, corresponds to the notification of which mode of the internal middle gaming state is staying if the current gaming state is the internal middle gaming state.

Further, when the notification condition of the setting suggestion effect is satisfied during the game of the player, the effect control unit 620 causes at least one of the liquid crystal screen 3 and the speaker 102 to notify the setting suggestion effect. The player can use this effect as a material for grasping the set value of the slot machine 1 currently being played. Examples of the notification condition include the time when the mode is changed, after the winning RB1, RB2, and RB3 have been won.

<About the game status>
During the game, the type of game state is switched based on various conditions. FIG. 6 shows the transition mode of the gaming state.

As described above, the game state control unit 615 switches the game state to any of "normal game state", "internal medium game state", and "RB execution state".

-Normal game state-
In the normal game state, all of the special roles RB1, RB2, and RB3 are in a non-winning and non-winning state, and a general game in which the player cannot receive the benefit of a large number of balls is advanced. Is.

The normal gaming state is when one of the set values has not been played yet, when the RAM has been initialized and the game has not been played yet, or when the slot machine 1 has just been shipped. It is set by the state control unit 615. That is, the default setting of the gaming state is the normal gaming state. Further, as shown in FIG. 6, the normal gaming state is set by the gaming state control unit 615 after the execution of the winning RB1, RB2, RB3 is completed.

Under the normal gaming state, as shown in FIG. 4, RB1, RB2, RB3, bell 1, bell 2, and replay are candidates for winning by internal lottery. The replay wins with a probability of 1 / 7.3, and if it wins, the replay can be performed regardless of the order in which the stop switches 40a, 40b, 40c, and 40d are pressed. The bell 1 is hit with a probability of 1 / 1.9, and when it is hit, one piece is paid out regardless of the order in which the stop switches 40a, 40b, 40c, and 40d are pressed. The bell 2 is hit with a probability of 1/50, and when it is hit, 15 pieces are paid out regardless of the order in which the stop switches 40a, 40b, 40c, and 40d are pressed.

By winning, RB1, RB2, and RB3 serve as a trigger for shifting the gaming state from the normal gaming state to the internal medium gaming state. With a probability of 1 / 3.2, one of RB1, RB2, and RB3 wins in duplicate with the one-card combination, but the distribution of which RB1, RB2, RB3 wins is RB1 "40%", RB2 is set to "10%" and RB3 is set to "50%".

When the RB1, RB2, and RB3 are hit, there is no correct pressing order for the stop switches 40a, 40b, 40c, and 40d. Therefore, when any of RB1, RB2, and RB3 is internally hit in the normal gaming state, the gaming state is normal regardless of the order in which the player presses the stop switches 40a, 40b, 40c, and 40d. The game state is changed to the internal medium game state.

As already described, when any of RB1, RB2, and RB3 wins, one card combination wins in duplicate. In the game of the winning timing, the winning combination is given priority over RB1, RB2, RB3, and the winning of RB1, RB2, RB3 is carried over. For example, if the symbol of the one-card combination is common regardless of the type of the winning RB, when the RB wins and the one-card combination wins, the player has a 50% chance of winning the RB3. It can be estimated that RB1 or RB2 is winning with a probability of remaining 50%.

In this embodiment, a case where any of RB1, RB2, RB3, bell 1, bell 2, and replay wins in each game and no loss occurs during the normal game state is illustrated. However, during the normal game state, the bell 2 which is a 15-card combination wins only with a probability of 1/50, and the RB1, RB2, RB3 and the bell 1 which have a higher winning probability than the bell 2 are all one. It is a role. Therefore, the number of medals cannot be expected to increase during the normal gaming state, and the payout rate under the normal gaming state is less than 100%.

By the way, as shown in FIG. 3, the bell design includes bell A, bell B, and a special bell. Of these, the symbol "special bell" constitutes the winning symbol combination pattern of the bell 2 (special bell-special bell-special bell).

On the other hand, the symbols "bell A" and "bell B" are one element constituting the winning symbol combination pattern of the bell 1 corresponding to the predetermined combination. Specifically, as shown in FIG. 7, the winning symbol combination pattern of the bell 1 is a symbol combination A (“Bell A-Bell A-Bell A-Bell A”” “Bell A-Bell A-Bell A-Bell A” in which the bell A or the bell B is aligned on the effective line L. "Bell A-Bell A-Bell B-Bell A" etc.) and "Replay" stops on the rotary reel 20a and "Bell A" "Bell B" "Bonus" on at least one of the other rotary reels 20b, 20c, 20d. Symbol combination B ("Replay-Replay-Replay-Bell A", "Replay-Replay-Bell A-Bell A", "Replay-Bell B-Bell A-Red"" stops. 7 ”, etc.) and.

The number of symbol combinations A is 16, and if any of the symbol combinations A wins, the number of medals to be paid out is 15. On the other hand, the number of symbol combinations B is larger than the number of symbol combinations A, and when any of the symbol combinations B wins, the number of medals paid out is one.

Internally, when the "bell 1" is won regardless of the game state, the symbol combination A and the symbol combination B are simultaneously won. However, depending on the type of gaming state, the rotary reel control unit 611 performs either reel control in which the number of symbol combinations is prioritized or reel control in which the number of payouts is prioritized among the symbol combinations A and B that are simultaneously won.

When the bell hits in the normal game state, the rotary reel control unit 611 has any of the symbol combinations B having a large number of winning symbol combinations depending on the pressing timing of the stop switches 40a, 40b, 40c, 40d and the like. With one of them aligned on the effective line L, the rotary reels 20a, 20b, 20c, and 20d are stopped, and control is performed to win the bell 1. That is, when the bell 1 is hit in the normal gaming state, the rotary reel control unit 611 controls the stop of the rotary reels 20a, 20b, 20c, 20d in which the number of symbols is prioritized (number of symbols priority control). Therefore, if the bell 1 wins and wins in the normal game state, one medal is paid out.

For example, it is assumed that the stop switch 40a is pressed while all the rotary reels 20a, 20b, 20c, and 20d are rotating in the normal gaming state. The rotary reel control unit 611 pulls in the replay so that the replay stops on the leftmost side on the effective line L. Next, the rotary reel control unit 611 pulls the bell A and the bell B into at least one of the rotary reels 20b, 20c and 20d at the timing when the other stop switches 40b, 40c and 40d are pressed.

Therefore, if the bell 1 is hit during the normal game state, the number of medals to be paid out will be one.

-Internal game state-
As shown in FIG. 6, the internal middle game state is a state in which one of the special roles RB1, RB2, and RB3 has won, but the prize has been carried over, and further, "RB1 internal medium state" and "RB2 internal". Includes "medium state" and "RB3 internal medium state". During the internal middle gaming state, the game state control unit 615 sets to any of "RB1 internal medium state", "RB2 internal medium state", and "RB3 internal medium state".

Until the winning RB1, RB2, RB3 are won, the set internal medium gaming state (specifically, one of the RB1 internal medium state, RB2 internal medium state, and RB3 internal medium state) is maintained. To. Therefore, for example, the gaming state is not changed from the “RB1 internal medium state” to the “RB2 internal medium state” or the “RB3 internal medium state”.

Regardless of whether the type of the internal medium game state is RB1 internal medium state, RB2 internal medium state, or RB3 internal medium state, the probability that each of the single combinations A to L in FIG. 5 will be won is 1/240. Suppose that

-RB1 internal medium state (Hamari mode)-
The internal middle state of RB1 is a state in which the winning of RB1 is carried over. As shown in FIG. 6, the gaming state is kept in the RB1 internal middle state among the internal middle gaming states from immediately after the RB1 wins in the normal gaming state until the RB1 wins a prize.

This RB1 internal medium state corresponds to the hamari mode. In the Hamari mode, the total probability of winning any of the single winning combinations A to D, which is the winning chance combination of RB1, is "4/240 (= 1/60)", so the chance of winning RB1 is "". It will arrive with a probability of 4/240 (= 1/60) ". When any of the single reels A to D is hit, the rotary reel control unit 611 stops the rotary reels 20a, 20b, 20b, 20d so that the single reels can be pulled in with a probability of "3/4". Take control. Therefore, in the Hamari mode, the winning of RB1 is successful with a probability of "1/4" when the 1-card winning combination A to D is won.

In view of this, it can be said that RB1 wins with a probability of 1/240 in the Hamari mode, which is the internal state of RB1. During this mode, as shown in FIG. 4, bells 1, bell 2 and replays are winning candidates, and the winning probability and the number of payouts of each of these combinations are the same as in the normal gaming state. That is, although the bell 1 wins at 1 / 1.9, the number of symbols to be paid out is one because the number of symbols is preferentially controlled as in the normal gaming state. Although the bell 2 is a payout of 15 cards, the winning probability is 1/50, which is lower than that of the bell 1. The replay wins at 1 / 7.3 as in the normal game state.

Moreover, as shown in FIG. 6, the end trigger of the Hamari mode is the winning of RB1, but the winning probability is 1/240. In other words, in this Hamari mode, it is not possible to expect an increase in the number of medals possessed, and in some cases it is expected that the player will stay for a long time. Therefore, in the Hamari mode, the player plays the game while hoping that the RB1 will be awarded as soon as possible.

It should be noted that this hamari mode corresponds to the first mode, and RB1 corresponds to the first special role among the special roles.

-RB2 internal medium state (pull-back mode)-
The internal middle state of RB2 is a state in which the winning of RB2 is carried over. As shown in FIG. 6, the gaming state is kept in the RB2 internal middle state among the internal middle gaming states from immediately after the RB2 wins in the normal gaming state until the RB2 wins a prize.

This internal internal state of RB2 corresponds to the pullback mode. In the pullback mode, the total probability of winning any of the one-card winning combination E to H, which is the winning chance role of RB2, is "4/240 (= 1/60)", so the chance of winning RB2 is " It will arrive with a probability of 4/240 (= 1/60) ". When any of the single reels E to H is hit, the rotary reel control unit 611 stops the rotary reels 20a, 20b, 20b, 20d so that the single reels 20a, 20b, 20b, and 20d can be pulled in with a probability of "1/4". Take control. Therefore, in the pullback mode, the winning of RB2 is successful with a probability of "3/4" when the 1-card winning combination E to H is won.

In view of this, it can be said that the RB2 wins with a probability of "3/240 (= 1/80)" in the pullback mode, which is the internal state of the RB2. During this mode, as shown in FIG. 4, bells 1, bells 2 and replays are winning candidates, and the winning probability and the number of payouts of each of these combinations are the same as in the normal gaming state and the hamari mode. That is, although the bell 1 wins at 1 / 1.9, the number of symbols to be paid out is one because the number of symbols is preferentially controlled as in the normal gaming state. Although the bell 2 is a payout of 15 cards, the winning probability is 1/50, which is lower than that of the bell 1. The replay wins at 1 / 7.3 as in the normal game state.

Moreover, as shown in FIG. 6, the trigger for ending the pullback mode is the winning of RB2, but the winning probability is 1/80. The winning probability (1/80) of RB2 in the pullback mode is higher than the winning probability (1/240) of RB1 in the hamari mode. In other words, although it is assumed that the stay in this pullback mode is shorter than that in the Hamari mode, the number of medals possessed cannot be expected to increase as in the Hamari mode. Therefore, in the pullback mode, the player plays the game with the expectation that the mode will be changed by winning the RB2 as soon as possible.

This mode corresponds to the third mode, and RB2 corresponds to the third special role among the special roles.

-RB3 internal medium state (small role concentration mode)-
The internal middle state of the RB3 is a state in which the winning of the RB3 is carried over. As shown in FIG. 6, the gaming state is kept in the internal middle state of the RB3 among the internal middle gaming states from immediately after the RB3 wins in the normal gaming state until the RB3 wins a prize.

This internal medium state of RB3 corresponds to the small winning combination mode. In the small role concentration mode, the total probability of winning any of the single roles I to L, which is the winning chance role of RB3, is "4/240 (= 1/60)", so the chance of winning RB3 is possible. Will arrive with a probability of "4/240 (= 1/60)". When any of the single reels I to L is hit, the rotary reel control unit 611 can pull in the single reel 20a, 20b with a probability of "2/4 (= 1/2)". , 20b, 20d stop control is performed. Therefore, in the small role concentration mode, the RB3 is won with a probability of "1/2" when the one-card combination I to L is won, but conversely, the RB3 is won with a probability of "1/2". Is avoided.

In view of this, it can be said that the RB3 wins with a probability of "1/120" in the small role concentration mode, which is the internal medium state of the RB3. During this mode, Bell 1, Bell 2 and Replay are winning candidates, as shown in FIG. Although the winning probability of each of these combinations is the same as that of the normal game state, only the payout number of bell 1 is different from the normal game state, the hamari mode, and the pullback mode.

Specifically, when the bell 1 is won, the rotary reel control unit 611 performs the number priority control instead of the symbol number priority control, so that the number of bells 1 won is 15 with a probability of 1 / 1.9. .. In addition, the bell 2 wins with a probability of 1/50, and 15 cards are paid out. The replay wins at 1 / 7.3 as in the normal game state.

That is, the winning probability does not change for Bell 1 (predetermined combination) in the small combination concentration mode, but the number of payouts at the time of winning is larger than that at the time of winning Bell 1 (predetermined combination) in the normal gaming state, the hamari mode and the pullback mode. Become. Therefore, the expected value of winning medals in the small role concentration mode is larger than the expected value of winning medals in each of the normal gaming state, the hamari mode, and the pullback mode.

However, as shown in FIG. 6, the trigger for ending the small role concentration mode is the winning of RB3, and the winning probability is 1/120. The winning probability of RB3 in the small role concentration mode (1/120) is higher than the winning probability of RB1 in the hamari mode (1/240), but higher than the winning probability of RB2 in the pullback mode (1/80). Low. In the small role concentration mode, which can increase the number of medals possessed, the player wants the RB3 not to win as much as possible. When the winning timing of the RB3 arrives, the player plays the game with relief by winning a prize when the stop switches 40a, 40b, 40c, and 40d are pressed. Therefore, the player's interest in the game increases.

In addition, this mode corresponds to the second mode, and RB3 corresponds to the second special role among the special role.

-RB implementation status-
As shown in FIG. 6, the RB implementation state is a state in which the winning RB1, RB2, RB3 are started immediately after winning a prize in the internal middle game state, and the winning RB1, RB2, RB3 are executed. It is in a state of being. The RB implementation state further includes "RB1 implementation state", "RB2 implementation state", and "RB3 implementation state". During the RB implementation state, the game state control unit 615 is set to any of "RB1 implementation state", "RB2 implementation state", and "RB3 implementation state".

While the gaming state is the "RB implementation state", the RB implementation state being set (specifically, the RB1 implementation state, the RB2 implementation state, the RB3 implementation state) until the digestion of the winning RB1, RB2, RB3 is completed. Either) is maintained. Therefore, for example, the gaming state is not changed from the “RB1 implementation state” to the “RB2 implementation state” or the “RB3 implementation state”.

-RB1 implementation status-
As shown in FIG. 6, the RB1 implementation state is a state in which the RB1 internal medium state is changed immediately after the RB1 wins a prize, and the game in the RB1 is digested.

The RB1 implementation state ends when the winning combination is won 8 times or 12 games are exhausted. As shown in FIG. 4, the candidate winning combinations during the RB1 implementation state are bell 1, bell 2, replay, and all winning combinations. The winning probability and the number of payouts for each of the winning combinations other than all the winning combinations are the same as those in the normal game state and the RB1 internal medium state. All the combinations are the combinations in which the 1-card combination and the 15-card combination are aligned at the same time, and the probability is, for example, 1/5.

-RB2 implementation status-
As shown in FIG. 6, the RB2 implementation state is a state in which the RB2 internal medium state is changed immediately after the RB2 wins a prize, and the game in the RB2 is digested.

Similar to the RB1 implementation state, the RB2 implementation state ends when the winning combination is won 8 times or 12 games are exhausted. The winning combinations, winning probabilities of each winning combination, and the number of payouts during the RB2 implementation state are also the same as in the RB1 implementation state.

-RB3 implementation status-
As shown in FIG. 6, the RB3 implementation state is a state in which the RB3 internal medium state is changed immediately after the RB3 wins a prize, and the game in the RB3 is digested.

Similar to the RB1 implementation state, the RB3 implementation state ends when the winning combination is won 8 times or 12 games are exhausted. The winning combinations, winning probabilities of each winning combination, and the number of payouts during the RB3 implementation state are also the same as in the RB1 implementation state.

When the digestion of each of the RB1, RB2, and RB3 is completed, the game state control unit 615 shifts the game state from the RB execution state to the normal game state. When any one of RB1, RB2, and RB3 wins under the normal gaming state, the mode shifts to the mode in the winning internal medium gaming state and the game is performed.

As described above, in the internal middle game state of the present embodiment, it is assumed that the number of medals possessed by the player cannot be expected to increase and the stay is long for each type of the special role RB1, RB2, RB3. "Hamari mode (RB1 internal medium state)", "pull back mode (RB2 internal medium state)" where you can expect a relatively quick transition to other modes although you can not expect an increase in medals, increase the number of medals possessed It includes three modes, "small role concentration mode (RB3 internal medium state)" that can be set. Which mode the game is played in is determined by which RB1, RB2, RB3 wins in the normal game state.

Each mode ends with the winning of the corresponding RB1, RB2, RB3, but in the present embodiment, the winning probability of each of the RB1, RB2, RB3 differs depending on the mode during the stay. Therefore, it can be said that how long the mode during the stay lasts depends on the luck and intuition of the player. In the "Hamari mode", the player wants to get out of the mode by winning the RB1 as soon as possible, and in the "pull-back mode", the RB2 is won as soon as possible to connect expectations to the next mode, and "small role". In the "concentrated mode", by avoiding the winning of the RB3, the winning can be postponed and the game can be played while hoping for a long stay in the mode. As described above, depending on the type of RB1, RB2, and RB3 hit in the normal gaming state, the game property in the RB internal middle state changes. Therefore, the player can enjoy the game whose development is uncertain and never gets tired.

Then, in the internal middle game state, which of the symbol number priority control and the number number priority control is performed as the control at the time of winning the bell 1 (predetermined combination) according to the type of the RB (special combination) in the inside. Is determined. According to the determined control, the rotary reel control unit 611 controls the rotary reels 20a, 20b, 20c, 20d. As a result, even if the same bell 1 is hit, the number of payouts can be changed depending on the type of the internal game state, so that it is possible to create a wave in which the number of balls to be acquired increases or decreases.

<Flow of operation processing of slot machine 1>
The flow of operation processing of the slot machine 1 according to this embodiment will be described with reference to FIG.

First, it is assumed that the game state control unit 615 sets the game state to the normal game state (step st1).

Each time the game is digested in the normal game state, the internal lottery unit 610 performs an internal lottery. When the bell 1 wins in this internal lottery, the rotary reel control unit 611 controls the stop of the rotary reels 20a, 20b, 20c in which the number of symbols is prioritized, so that one medal is paid out.

When the RB wins in the internal lottery in the normal game state (Yes in step st2), the game state control unit 615 shifts the game state from the normal game state to the internal middle game state (step st3).

When the RB hit in step st2 is RB1 (Yes in step st4), the internal middle game state in step st3 is set to the hamari mode, which is the internal middle state of RB1 (step st5). After that, since the game is advanced in the Hamari mode, if the bell 1 is won, one medal is paid out by the symbol number priority control.

In the Hamari mode, if any of the 1-card combination A to L is established (winning) (Yes in step st6) and the 1-card combination is won without being missed (No in step st7), RB1 is not. It will be a prize (step st8).

In particular, when the one-card winning combination established in step st6 is a winning chance combination (one of the one-card winning combination A to D), it means that the opportunity to win the RB1 has arrived. In this case, if the one-card combination wins (No in step st7), RB1 does not win (step st8). On the other hand, if the one-card combination is missed by pressing the stop switches 40a, 40b, 40c, 40d (Yes in step st7), RB1 wins a prize (step st9).

If the 1-card combination is not established in step st6 (No in step st6), the game in the Hamari mode is continued until any of the 1-card combination A to L is established next.

When the RB1 wins in step st9, the game state control unit 615 shifts the game state from the RB1 internal medium state to the RB1 implementation state. As a result, RB1 is carried out until the small winning combination is won 8 times or 12 games are completed (step st10).

When the RB hit in step st2 is RB2 (Yes in step st11), the internal middle game state in step st3 is set to the pullback mode, which is the internal middle state of RB2 (step st12). After that, since the game is advanced in the pullback mode, if the bell 1 is won, one medal is paid out by the symbol number priority control.

In the pullback mode, if any of the 1-card combination A to L is established (winning) (Yes in step st13) and the 1-card combination is won without being missed (Yes in step st14), RB2 is not. It will be a prize (step st15).

In particular, when the one-card combination established in step st13 is a winning chance combination (one of the one-card combination E to H),
The opportunity to win the RB2 will come. In this case, if the one-card combination wins (No in step st14), RB2 does not win (step st15). On the other hand, if the one-card combination is missed by pressing the stop switches 40a, 40b, 40c, 40d (Yes in step st14), RB2 wins a prize (step st16).

If the 1-card combination is not established in step st13 (No in step st13), the game in the pullback mode is continued until any of the 1-card combination A to L is established next.

When the RB2 wins in step st16, the game state control unit 615 shifts the game state from the RB2 internal medium state to the RB2 implementation state. As a result, RB2 is carried out until the small winning combination is won 8 times or 12 games are exhausted (step st17).

When the RB won in step st2 is RB3 (Yes in step st18), the internal middle game state in step st3 is set to the small role concentration mode, which is the internal middle state of RB3 (step st19). After that, since the game is advanced in the small role concentration mode, if the bell 1 is won, 15 medals are paid out by the payout number priority control.

In the small role concentration mode, if any of the 1-card combination A to L is established (winning) (Yes in step st20) and the 1-card combination is won without being missed (No in step st21), RB3 Will not win (step st22).

In particular, when the one-card combination established in step st20 is a winning chance combination (one of the one-card combination I to L),
The opportunity to win the RB3 has arrived. In this case, if the one-card combination wins (No in step st21), RB3 does not win (step st22). On the other hand, if the one-card combination is missed by pressing the stop switches 40a, 40b, 40c, 40d (Yes in step st21), RB3 wins a prize (step st23).

When the 1-card combination is not established in step st20 (No in step st20) Next, the game in the small combination concentration mode is continued until any of the 1-card combination A to L is established.

When the RB3 wins in step st23, the game state control unit 615 shifts the game state from the RB3 internal medium state to the RB3 implementation state. As a result, RB3 is carried out until the small winning combination is won 8 times or 12 games are exhausted (step st24).

Until the player finishes the game (No in step st25), the operations after step st1 are repeated. When the player finishes the game (Yes in step st25), the slot machine 1 ends a series of operations.

Summarizing the above, the slot machine 1 (game machine) starts rotation of a plurality of rotary reels 20a, 20b, 20c, 20d in which a plurality of symbols are arranged, and a plurality of rotary reels 20a, 20b, 20c, 20d. A lever 43 (start switch) that accepts an operation for causing the rotation, a stop switch 40a, 40b, 40c, 40d that accepts an operation for stopping the rotation of a plurality of rotary reels 20a, 20b, 20c, 20d, and a lever 43 (start). An internal lottery unit 610 that performs an internal lottery based on the operation of the switch) and determines whether or not at least one of the plurality of combinations has won, a lever 43 (start switch), and stop switches 40a, 40b, 40c, 40d. The rotary reel control unit 611 that controls the rotation of the plurality of rotary reels 20a, 20b, 20c, and 20d based on each operation, and RB1, RB2, RB3 (special combination) among the plurality of roles are not won and won no prize. The normal gaming state, which is RB1, RB2, RB3 (special role) won, but the prize is carried over to the internal middle game state, and the winning RB1, RB2, RB3 (special role) starts immediately after winning. It includes a game state control unit 615 that controls switching between an RB execution state (special combination implementation state) and a game state including the RB execution state, and a plurality of combinations include RB1 (first special combination) and RB3 (first special combination) included in the special combination. 2 special role) and bell 1 (predetermined role) in which the number of medals (game media) to be paid out is paid out regardless of the operation procedure of the plurality of stop switches 40a, 40b, 40c, 40d. The states are the hamari mode (first mode), which is transitioned by hitting RB1 (first special role) during the normal gaming state, and RB3 (second special role) winning during the normal gaming state. The number of payouts at the time of winning the bell 1 (predetermined combination) in the small combination concentration mode (second mode), including at least the small combination concentration mode (second mode) transitioned in, is in the hamari mode (first mode). Since the number of payouts at the time of winning the bell 1 (predetermined combination) is larger than the number of payouts, the expected value of the medal (game medium) in the small combination concentration mode (second mode) is larger than that in the hamari mode (first mode). ..

<Effect>
In this embodiment, there are at least a small role concentration mode in which medals can be obtained without being aware of the operation procedure of the stop switches 40a, 40b, 40c, and 40d, and a hamari mode in which medals cannot be expected to be obtained. Whether it can be done is determined by which RB1 and RB3 win in the normal gaming state. Therefore, the game is unlikely to be a monotonous task, and an interesting game is developed.

Further, the winning probability of RB1 (first special role) in the hamari mode (first mode) can be different from the winning probability of RB3 (second special role) in the small role concentration mode (second mode). In the present embodiment, the winning probability of RB1 (first special role) in the hamari mode (first mode) is lower than the winning probability of RB3 (second special role) in the small role concentration mode (second mode). .. As a result, the stay in the hamari mode tends to be longer than the stay in the small role concentration mode, but the actual length of stay depends on the luck of the player and can be uncertain. Since the development of the game is left to each player, the player can enjoy the game without getting tired of it.

Further, the internal middle gaming state can further include a pull-back mode (third mode) in which the RB2 (third special combination) is hit during the normal gaming state to make a transition. The number of payouts at the time of winning the bell 1 (predetermined combination) in this pullback mode is smaller than the number of payouts at the time of winning the bell 1 in the small winning combination mode (second mode). Therefore, the expected value of winning medals in the pullback mode (third mode) is smaller than that in the small winning combination mode (second mode). However, the winning probability of RB2 (third special role) in the pullback mode (third mode) is higher than the winning probability of RB1 (first special role) in the hamari mode (first mode). As a result, the game quality is further changed, and the development becomes more uncertain.

Further, when the bell 1 (predetermined combination) is hit in the hamari mode (first mode), the rotary reel control unit 611 arranges the maximum combination of the symbol combinations corresponding to the bell 1 on the effective line L. It is possible to perform symbol number priority control for stopping the rotary reels 20a, 20b, 20c, 20d based on the operation of the stop switches 40a, 40b, 40c, 40d. On the other hand, when the bell 1 (predetermined combination) is won in the small combination concentration mode (second mode), the rotary reel control unit 611 has a larger number of predetermined number of symbols than the maximum combination among the symbol combinations corresponding to the bell 1. The number priority control for stopping the rotary reels 20a, 20b, 20c, 20d can be performed based on the operation of the stop switches 40a, 40b, 40c, 40d so that the combination is arranged on the effective line L. As a result, a specification is realized in which the number of bells 1 to be paid out changes according to the type of mode.

Further, when the bell 1 (predetermined combination) is hit during the normal gaming state, the rotary reel control unit 611 can perform symbol number priority control. As a result, it is possible to realize that the expected value of winning medals in the small role concentration mode (second mode) is larger than that in the normal gaming state.

Further, the effect control unit 620 (notification control unit) can notify the notification unit such as the liquid crystal screen 3 or the speaker 102 of the stay mode in the internal game state. This allows the player to know which mode he is currently staying in.

In addition, the game state control unit 615 ends the stay mode during the internal middle game state with the winning of RB1, RB2, RB3 (specific combination) that triggered the mode transition, and the winning RB1, RB2. , The gaming state can be switched to the RB implementation state (special combination implementation state) of RB3 (special role). As a result, how long the mode during the stay will continue depends on the winning of RB1, RB2, RB3. Therefore, the player can enjoy the game whose development is uncertain and never gets tired.

Further, the game state control unit 615 is RB3 (second specific) based on the operation mode which is the pressing timing of the stop switches 40a, 40b, 40c, 40d while staying in the small winning combination mode (second mode) in the internal middle game state. Depending on whether or not the winning combination is possible, the continuation or termination of the small combination concentration mode (second mode) can be determined. That is, it can be said that whether or not the RB1, RB2, and RB3 can be won depends on the luck and intuition of the player.

[Other embodiments]
The various control means and processing procedures described in the embodiments are examples and are not intended to limit the scope of this disclosure, its applications, or its uses. Various control means and processing procedures can be appropriately redesigned without changing the gist of the present disclosure.

In the above embodiment, both the RAM clear button 71 and the setting change button 72 are provided, and when any of the buttons 71 and 72 is pressed, the current gaming state is set to the normal gaming state (reset). I explained. However, only one of the RAM clear button 71 and the setting change button 72 may be provided. Further, even if the setting change button 72 is pressed, the gaming state may be inherited from the state before the pressing, and the gaming state may be reset only when the RAM clear button 71 is pressed.

The trigger for which the game state reset process is performed may be other than pressing the buttons 71 and 72. For example, the game state reset process may be performed by temporarily disconnecting the harness that electrically connects the main control unit 61 and the sub control unit 62.

Further, a button for receiving an execution instruction of the reset process of the gaming state may be provided outside the housing 10 so that the player can press the button. That is, at the player's will, the gaming state during the stay may be switched to the "normal gaming state" set by default.

In the above embodiment, the winning probability and winning probability of RB1, RB2, RB3, the winning distribution of RB1, RB2, RB3, the winning probability of bell 1, and the like, which are special roles, may be different depending on the set value. For example, the higher the set value, the lower the winning probability of RB1 and RB2 and the higher the winning probability of RB3, or the higher the winning probability of RB1 and RB2 and the lower the winning probability of RB3. Can be done. The higher the setting value, the higher the probability of bell 1 can be set.

In the above embodiment, the case where the winning probability of each winning combination is the same in each mode is illustrated, but it may be different depending on each mode.

In the above embodiment, the case where the special role is RB is exemplified. However, the special role may be other than RB. For example, the special role can be type 1 BB or type 2 BB. The special role may be a bonus, and the specification may be such that two or three medals are paid out by multiplying two medals while the bonus is being won (during the special role implementation state). As a result, the number of medals obtained by the bonus is approximately 0, slightly increased or slightly decreased.

In the above embodiment, the number of bets (2 bets, 3 bets) may be different between the time of winning the RB and the time of winning.

In the above embodiment, it has been described that when the RB wins, one card combination wins at the same time, but the present invention is not limited to this. When the RB wins, the RB may win alone, or a role other than the one-card role (replay, three-card role, etc.) may win at the same time as the RB, and the prize may be given priority over the RB. .. When the RB wins alone, the effect control unit 620 can notify the liquid crystal screen 3 and the speaker 102 of the procedure for removing the winning of the RB. As a procedure in this case, it is possible to aim and press a specific symbol at a predetermined timing by pressing the button.

In the above-described embodiment, when the one-card combination, which is a winning chance combination, is established in the RB internal middle game state, the one-card combination is dropped instead according to the pressing timing of the stop switches 40a, 40b, 40c, 40d. It was explained that the corresponding RB1, RB2, RB3 won a prize and the corresponding mode ended. However, the difficulty (or ease) of winning the RB1, RB2, and RB3 may change depending on the combination of the operation timing and the operation order of the stop switches 40a, 40b, 40c, and 40d.

Further, the small winning combination mode ends depending on whether or not the RB3 can win a prize according to the operation mode of the stop switches 40a, 40b, 40c, 40d, while the hamari mode and the pullback mode end by consuming the fixed number of games. RB2 may win and finish.

In the above-described embodiment, the case where there are three modes of the internal game state is illustrated. However, the internal middle game state may have at least two modes, a hamari mode and a small winning combination mode, and may not have a pullback mode. Further, the number of modes in the internal middle game state may be four or more. For example, even if the special mode, which is expected to continue for a long period of time because the winning probability of the RB4 is significantly lower than that of the small role concentration mode, is included as the internal middle game state when the special role RB4 wins. good. In the special mode, the operation execution of the stop switches 40a, 40b, 40c, 40d related to the winning of the RB4 may be announced via the notification unit at a timing unrelated to the winning of the RB4. For example, at the timing when the RB4 does not actually win the prize, the effect of "choose forward push or reverse push" is notified. In this case, no matter which push order is made, the RB4 will not win a prize and the special mode will continue. As a result, the player can proceed with the game while thinking that the RB4 did not win because the push order was correct due to his or her luck and intuition.

In the above embodiment, when a predetermined condition such as winning a special replay is satisfied after the end of the RB implementation state of FIG. 6, for example, while three games are digested after the end, the game state control unit 615 is in the game state. May be switched to a high replay state in which the probability of winning the replay is higher than that in the normal game state. The number of continuous games in the high replay state may be fixed, or continuation or termination may be determined depending on the operation mode of the stop switches 40a, 40b, 40c, 40d by the player. If the RB1, RB2, and RB2 win while the high replay state is continuing, the game state control unit 615 shifts the game state from the high replay state to the internal medium game state without going through the normal game state. Can be done. If the above-mentioned predetermined conditions are not satisfied after the end of the RB implementation state, the game state control unit 615 causes the game state to stay in the normal game state.

In the above embodiment, the case where the slot machine 1 includes the liquid crystal screen 3 is illustrated. However, the slot machine 1 may be provided with an LED or the like that illuminates a pattern instead of the liquid crystal screen 3.

In the above embodiment, the case where the rotary reel is 4 reels has been described. However, the number of rotary reels may be a plurality, and may be three reels.

In the above-described embodiment, the case where four stop switches 40a, 40a, 40d are provided so as to correspond to the four rotary reels 20a, 20b, 20c, and 20d, respectively, has been described. However, the number of stop switches may be three. One of the four rotary reels is used as a production reel, and one of the three stop switches is used to rotate the production reel and one of the three rotary reels related to ball ejection. It may be a specification that can be stopped at the same time.

In the above-described embodiment, the effect control unit 620 may notify the player of how the game state has changed and the transition of the ball output through the effect or history screen.

In the above embodiment, the case where the bet switch 42 is provided is illustrated, but the bet switch 42 may not be provided. In this case, the lever 43 can also serve as a medal betting function by the bet switch 42.

In the above-described embodiment, when the one-card combination, which is a winning chance combination, is won, the opportunity to win the RB1, RB2, RB3 has arrived, but the one-card combination has won the prize, and the RB1, RB2, RB3 If the prize cannot be won, the effect control unit 620 can miss the correct answer information for winning the RB1, RB2, RB3, that is, at what timing the stop switches 40a, 40b, 40c, 40d are pressed. The information may be notified to the player via at least one of the liquid crystal screen 3 and the speaker 102.

In the above-described embodiment, the case where the internal lottery unit 610 wins any of a plurality of winning combinations, that is, the case where any winning combination is always won by the internal lottery has been described. However, depending on the internal lottery, there may be a case of "missing" in which neither role is won. In this case, the internal lottery unit 610 determines whether or not at least one of the plurality of combinations has been won. In the case of disconnection, one game ends with the corresponding rotary reels 20a, 20b, 20c, 20d stopped according to the operation of the stop switches 40a, 40b, 40c, 40d, but the medals are not paid out. can do.

In the above-described embodiment, it has been explained that in the small winning combination concentrating mode, when the winning winning combination I to L is won, the one-card winning combination is controlled to be dropped by 1/2. However, even in the small role concentration mode, as in the Hamari mode, control may be performed in which one card combination is dropped by 1/4 when the one-card combination I to L, which is a winning chance combination, is won. .. As a result, the duration of the small role concentration mode is longer than that of the above-described embodiment, so that the player can expect more by acquiring the balls.

In addition to the small winning combination mode, a ball ejection increase mode (corresponding to the fourth mode) may be provided. The payout increase mode is a mode in which the transition is made by hitting the RB4 (corresponding to the fourth special role) during the normal game state. In this payout increase mode, as in the small winning combination mode, the number of payouts when winning the bell 1, which is a predetermined winning combination, is larger than in the hamari mode. Furthermore, in the payout increase mode, the difficulty of winning the RB4 is higher than the difficulty of winning the RB1, RB2, RB3 in the other modes (hamari mode, pullback mode, small role concentration mode). The expected value of winning medals is higher than in other modes. The difficulty of winning the RB4 is realized by setting the winning conditions of the RB4 to, for example, the same specifications as the RB1, and further adding a stop timing and an operation order such as which symbol is aimed at in what order. Since the winning conditions of RB4 become stricter than the winning conditions of RB1 to RB3, it becomes difficult for RB4 to win a prize, and it becomes difficult to end the mode in which the number of balls is increased. By that amount, the player's expectation of getting a ball will increase, and the fun of the game will further increase.

In the above embodiment, the case where the concept of the advantageous interval does not exist is illustrated. However, as a game section, a normal section and an advantageous section may exist. The advantageous section is a section in which the instruction function applied in the order of pushing can be exerted. In this case, if it is between advantageous sections and the mode is Hamari mode, the winning procedure (pushing order for winning) of RB1 is determined by a predetermined condition such as playing a predetermined number of games in Hamari mode. When it is satisfied, it can be notified. Further, if it is between advantageous sections and the mode is a small winning combination mode, an operating procedure for avoiding the winning procedure of RB3 (operation timing for missing one winning combination, which is a winning chance combination). May be notified. In the small role concentration mode, the period for notifying the operation procedure for avoiding the winning of the RB3 may be limited, such as from the start of the small role concentration mode to the game of a predetermined number of games. .. Further, the number of times to notify the operation procedure for avoiding may be determined by a lottery or the like, triggered by the number of game games in other modes (hamari mode, pullback mode) or the winning of some role.

In the above embodiment, as shown in FIG. 5, it is determined that each of the single card combinations A to L is a winning chance combination in any one of the RB1 internal medium state, the RB2 internal medium state, and the RB3 internal medium state. The case where it is done is illustrated. However, the one-card role may include a role that is a winning chance role in any RB internal medium state, or may include a role that is not a winning chance role in any RB internal medium state. good.

In addition, if the 1-card combination is a common winning chance role in any RB internal state, the RB can be won (that is, the 1-card combination can be missed) depending on the type of RB inside. The timing of pressing the stop switch 40, which is the correct answer, may be different.
