Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine installed and used in a game hall such as a pachinko parlor.

[0002]

2. Description of the Related Art In the present specification, a pachi-slot machine is used as an example for explanation. Therefore, a medal is used as a game medium, but the game medium includes other media such as coins and pachinko balls. In addition, in "insert medal (game medium)",
In addition to actually inserting a medal into the medal insertion slot, betting a credited medal with a bet button or the like is included. In addition, it is possible to win the winning combination by electronic lottery, and it is possible to arrange the winning patterns that make up the winning combination on the winning effective line. The state of being aligned on the winning effective line is the winning.

A slot machine installed and used in a game hall such as a pachinko parlor is called a pachi-slot machine, and a medal, which is a game medium, is given a certain value to win a medal obtained by playing a game. It can be exchanged for various prizes. Therefore, the player generally attempts to play the game by only selecting a platform that is easy to obtain the right to shift to the bonus game mode for the purpose of obtaining a large number of medals. The bonus game modes include, for example, a big bonus (BB) mode and a regular bonus (RB) mode. In particular, the BB mode is changed to the RB mode a predetermined number of times, and before the transition to the RB mode, a small role is played. Since the mode is shifted to the RB introduction mode in which the winning probability of is increased, a large number of medals can be acquired in a short period of time.

It is an important factor to attract the player to the slot machine to hold the expectation that a large number of medals can be won in a short period of time, and various measures have been taken in order to encourage the player's euphoria. Many models tend to be provided. As one of such models, for example, a model provided with a so-called stock function is provided, in which the winning BB or RB is stored when the winning BB or the RB shifting to the RB mode is won. ing.

Some models provided with a stock function are provided with a game mode called a stock time (ST) mode, for example. ST mode is, for example, B
When the player wins B, the transition is made, and in the ST mode, the probability of winning the replay that allows the next game to be played without inserting medals is increased. Therefore, during the ST mode, the player can take a lottery to determine the winning combination while suppressing the consumption of medals. And, during ST mode, BB
When the RB and the RB are stored, the stored BB and the RB are released after the end of the ST mode, and the BB mode and the RB mode are continuously shifted. In models with ST mode, if multiple BBs and RBs are stocked, BB mode and R
Since the mode is repeatedly switched to the B mode, it is possible to acquire a large number of medals in a short period of time. Therefore, the player's interest in the game can be increased.

[0006]

However, in the above slot machine, since BB and RB are randomly selected, the BB and RB can be randomly selected to maintain the player's expectation. While it can be done, BB and RB
Bias may occur in the lottery. In this way, the inability to finely control the payout rate by software causes a significant disadvantage to the amusement hall side, and conversely when the amusement hall side wants to give a profit to the player, it cannot be done. It was one of the causes of the trouble.

In order to solve the above problems, it is an object of the present invention to provide a game machine, a program, and a recording medium in which the payout rate can be finely controlled by software.

And a winning combination determining means for determining any one of a plurality of winning combinations by lottery, the reel stop control is performed to facilitate winning of the winning combination determined by the winning combination determining means, and the winning combination is determined. When the special winning combination is determined by the means, in the gaming machine configured to store the special winning combination without performing reel stop control so that the special winning combination can be easily won, In the case where the winning probability of the special winning combination in the lottery is set to be substantially the same, and when the special winning combination is stored, the fact that a specific condition in the game is satisfied is triggered,
A winning combination releasing lottery means for determining whether or not the reel stop control is performed to facilitate winning of the special winning combination by lottery using one of a plurality of types of winning combination releasing tables having different releasing probabilities. Is provided.

It is preferable to provide a winning combination releasing probability determining means for determining which of the plurality of types of winning combination releasing tables should be used to cause the winning combination releasing lottery means to perform a lottery.

Further, the winning combination release probability determining means performs a lottery using a preset emission probability determining table among a plurality of types of releasing probability determining tables having different selection probabilities in the winning combination releasing table. Is preferred.

When the special winning combination is obtained,
It is preferable to provide a special mode executing means for executing the game in the special mode in which the probability of the player's profit giving is higher than that in the normal mode. This can increase the player's expectation of obtaining a large number of medals.

The program to be used is a winning combination determining means for determining one of a lot of winning combinations and a plurality of kinds of winning combinations by lottery, and when a special winning combination is stored, a specific condition in the game is satisfied. Whether or not the reel stop control is performed so that the special winning combination can easily win the prize,
This is for causing the computer of the gaming machine to function as a winning combination releasing lottery means which is determined by a lottery using any one of a plurality of winning combination releasing tables having different releasing probabilities.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the slot machine 10 is provided with a BB mode which is a normal mode and a special mode. The BB mode ends when the game is transferred to the RB mode three times or the game in the RB introduction mode is played 30 times. In RB mode, the predetermined winning pattern is 8
The game ends when the player wins a prize or plays 12 games. If you win the special winning BB in normal mode, you get B
B is stored. Then, when a cherry is won in the game in the normal mode, a BB release lottery is performed to determine whether or not to release the stored BB. When the BB release lottery is performed, the probability of winning the replay that allows the next game to be played without inserting a game medium during a certain number of game periods is increased.

When the BB release lottery is won, the reel stop control is performed so that the BB can be won after a certain number of games. The BB release lottery is performed based on two types of probabilities. The BB release mode is a mode in which the BB release lottery is performed with a high probability, and the BB release mode is a state in which the BB release lottery is performed with a low probability. It is set to B mode.

In the slot machine 10, four display windows 13 are provided on a front door 12 of a housing 11, and each display window 13 is provided.
A first reel 14a, a second reel 14b, a third reel 14c, and a sub reel 15 are rotatably incorporated in the inner part of the disk. As is well known, the first to third reels 14a to 14c
A plurality of types of patterns are arrayed at a constant pitch on the outer periphery of, and three patterns per reel can be observed through the display window 13 when the reels are stopped. As a result, a total of 5 linear winning pay lines in which the patterns of the respective reels are combined one by one and three diagonally by two are set.

The medal slot 16 prior to the start of the game
When one medal is thrown from, one horizontal winning line is activated in the center, and two horizontal lines, three horizontal lines and three diagonal lines, two diagonal lines are activated. . Further, it is possible to credit (store) up to 50 medals, and the number of credited medals is displayed by the credit number display unit 17. It is to be noted that, for example, four reels can be observed from the display window 13 per reel, and in addition to the four horizontal winning lines, another reel that is bent to combine one reel for each reel It is also possible to set an effective line.

The sub reel 15 at the right end is rotated together with the first to third reels 14a to 14c when the start lever 18 is operated when BB internally wins the game in the normal mode. "BB" indicating that BB has won the internal winning is drawn on the sub reel 15, and a blank portion where nothing is drawn is also provided. Sub reel 15
Is normally stopped at a position where a blank portion is displayed, and is stopped at a position where "BB" is displayed when the BB has won an internal prize. The display indicating that the BB has won the internal prize is not limited to "BB", and may be appropriately displayed by a picture or a mark. In addition, winning combinations other than RB such as BB and small winning combinations may be displayed. In this case, it is preferable not to display the loss before the reel stop operation is performed.

By operating the stop buttons 19a to 19c, the stop buttons 19a to 19c correspond to the first to third buttons corresponding to the respective buttons.
The reels 14a to 14c are individually stopped. Various operation buttons such as a 1 bet button, a MAX bet button, and a payout button, which are operated when a game is played with a medal credited, are provided on the operation panel above the stop buttons 19a to 19c. Since the functions of these operation buttons are well known, their details are omitted.

A medal tray 20 is provided in the lower portion of the housing 11, and the medal tray 20 is provided with payout medals 2 for payout medals obtained when a prize is won in a game.
It is paid out from 1.

As shown in FIG. 2, a power supply box 22 is provided below the inside of the housing 11. Power supply box 2
Power switch 23, setting change button 2 on the front of 2

When the setting change button 24 is operated, the payout rate of the slot machine 10 is selected. The slot machine 10 is provided with six payout rates, and each time the setting change button 24 is pushed, the payout rate is sequentially switched one step at a time. When the setting change button 24 is operated seven times or more, the initial payout rate is restored, and the payout rate in six stages is sequentially switched again. A corresponding setting key 26 is inserted into the keyhole 25. When the power switch 23 is turned off, the setting key 26 is turned to the on position, and when the power switch 23 is turned on thereafter, the setting change button 24 can be operated. After the payout rate is selected with the setting change button 24, the setting key 26
When is turned to the off position, the game can be played and the setting of the payout rate for one time is completed.

As shown in FIG. 3, the operation of the slot machine 10 is basically controlled by a microcomputer including a CPU 30 and a memory 31. In addition to the control unit 30a, the CPU 30 includes an electronic lottery unit 39, a winning combination determination unit 40, a BB flag storage unit 42, a BB release lottery unit 43, which will be described later.
A BB emission signal generation unit 44, an emission mode selection lottery unit 45,
A replay probability varying unit 46 and a replay probability determining unit 47 are provided.

The medal sensor 32 detects a proper medal inserted from the medal insertion slot 16 and inputs it to the control section 30a. A selector is incorporated in the rear of the medal insertion slot 16, and improper medals are ejected to the medal tray 20.
Also, when the selector inserts medals at improper timing, for example, for medals inserted in the middle of the game or while various operation buttons are being pressed,
The coins are discharged to the medal tray 20 without passing through the medal sensor 32.

Since the number of medals to be inserted prior to the start of the game is limited to 1 to 3, the medal sensor 32 also detects medals inserted after the 4th one when the credit function is not used. It is discharged to the medal tray 20 without being played. The credit function is switched on / off for each push of the payout button. Then, when the credit function is turned on, medals inserted after the fourth one are also detected by the medal sensor 32, and 5
A maximum of 0 cards will be credited inside the slot machine.
The number of credited medals is digitally displayed on the credit number display unit 17. When the credit function is used, a medal insertion operation is performed by operating the 1 bet button or the MAX bet button, and the bet number is sequentially subtracted from the credit number. Also,
When a game is played and a prize accompanied by payout of medals is obtained, a dividend medal is also credited, and when the payout button is operated, the credited medal is paid out to the tray 20.

The control unit 30a determines the number of medals inserted from 1 to 3 prior to the start of the game by the medal sensor 32.
Based on the detection signal from, the number of activated winning lines is determined. The number of credits is counted by another credit medal counter (not shown).

The start signal sensor 33 inputs a game start signal to the control section 30a when the start lever 18 is operated after one to three medals have been inserted. In response to the game start signal, the control unit 30a causes the memory 31
The first to third reels 14a to 14c are rotated based on the game execution program stored in the ROM area, and the game process is started. The game execution program includes a program that shifts to the BB mode in addition to the normal mode and executes the game processing. As a result, the control unit 30a functions as a special mode executing means.

The reel drive controller 34 controls the drive and stop of each reel. Each reel is fixed to the drive shaft of each individual stepping motor 35a to 35d, and each reel is controlled by controlling the drive of each stepping motor 35a to 35d. The RAM area of the memory 31 is a working area, and is used for temporary storage and rewriting of flags and data used for each game.

Since the stepping motors 35a to 35d rotate at a rotation angle corresponding to the number of drive pulses supplied, the control unit 30a controls the number of drive pulses supplied to the first to third reels 14a to 14c. The rotation angle of the sub reel 15 can be controlled, and the stop position of the reel can be determined by cutting off the supply of the drive pulse. Reflection signal portions 36a to 36d are integrally formed on the respective reels at their reference positions, and photosensors 37a to 37d photoelectrically detect the passage of the respective reflection signal portions at each rotation thereof. Detection signals from the photo sensors 37a to 37d are input to the control unit 30a as a reset signal for each reel.

The stepping motor 3 is installed in the control unit 30a.
A pulse counter is provided for each of 5a to 35d and counts the number of drive pulses supplied to each stepping motor 35a to 35d. Then, the photo sensor 37a-
When the reset signal is input from 37d, the count value of the corresponding pulse counter is cleared. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is sequentially updated and stored in each pulse counter.

A pattern table is stored in the ROM area of the memory 31. The pattern table stores the number of drive pulses corresponding to the rotation angle of each reel from the reference position and each pattern arranged on the reel at a constant pitch. Is associated with the picture code representing. Therefore, by monitoring the count value of the pulse counter for each reel, it is possible to identify, for example, which pattern is moving on the winning line in the center, and how much more the reel is rotated. It is possible to predict whether the target pattern will move to the winning effective line.

The stop button sensors 38a-38c are
When the stop buttons 19a to 19c are operated, a stop signal for each reel is input to the control unit 30a. The start lever 18 is operated to start rotation of all reels, and when these rotations reach a steady speed, the stop button 1
The operations 9a to 19c are activated. Then, by operating these, stop control of the corresponding first to third reels 14a to 14c is started.

The stop control of the first to third reels 14a to 14c is performed within the range of four winning symbols (withdrawal range). For example, when the stop buttons 19a to 19c are operated, on the winning line. In the case where the winning pattern that constitutes the winning combination that is won in the lottery is included in the four winning patterns that continue from the winning pattern located in
The time until the third reels 14a to 14c are stopped is delayed, and the winning symbols constituting the winning combination are stopped on the winning effective line. It should be noted that when a plurality of stop buttons are operated, only the reel with the earlier timing is stopped, and when completely simultaneously operated, none of the reels is stopped. Further, the reel stop control is not limited to the winning pattern that constitutes the winning combination, but notifies the player of the winning combination that is internally won by the type of the pattern stopped on the winning effective line or the combination of the patterns, so-called The reach eyes may be displayed.

The control section 30a receives the game start signal and operates the electronic lottery section 39. The electronic lottery section 39 includes a random number generator and a random value sampling circuit, and randomly selects one random value each time the game is started. The randomly selected random number value is input to the winning combination determination unit 40. The winning combination determination unit 40 determines what kind of winning combination will be given in the currently executed game according to the input value. In this way, the electronic lottery section 39 and the winning combination determining section 40 function as winning combination determining means.

As shown in FIG. 4, the winning combination determining section 40 is provided with a plurality of winning combination lottery tables in which random number values are divided into groups according to their sizes. In the first winning combination lottery table 41, the random number sampled in the game in the normal mode gives the right to shift to the BB mode.
B, a small role corresponding to a small-winning winning pattern that only pays out a predetermined number of medals, a replay that gives the right to play the next game with the same bet number without inserting medals, a loss that does not cause any hits, etc. It is used to determine whether or not it belongs to a pattern, that is, to determine whether or not it is a winning prize. It should be noted that there are a plurality of types of small winning symbols, and a payout medal is assigned to each of them. Then, the type of winning and the design are determined depending on which winning design the sampled random number value belongs to.

The first winning combination lottery table 41 is composed of first to sixth setting tables 41a to 41f. In the first to sixth setting tables 41a to 41f, the random number groups are grouped differently from each other, and the payout rate of the slot machine 10 is changed by switching and using these setting tables. The first
The payout rates of the sixth setting tables 41a to 41f are set to be substantially the same. Note that the first winning combination lottery table 41 may be configured by setting tables of appropriate types. Further, it is preferable that the payout rates of the first to sixth setting tables 41a to 41f are set appropriately.

In addition to the first winning combination lottery table 41, the winning combination determining section 40 has a table used for a game in which the BB has won an internal prize, a game in the RB introduction mode, a game in the RB mode, and the like. Replay winning probability table 40 used in the game after winning the BB release lottery
a and the like are provided. In the replay winning probability table 40a, the random number values are grouped so that the replay winning probability is higher than that in the first to sixth setting tables 41a to 41f. When the winning combination determination unit 40 determines whether or not the winning combination is achieved, a winning combination determination signal indicating the determined loss or the type of winning combination is input to the control unit 30a.

When the setting change button 24 is operated and the payout rate is selected, a payout rate selection signal is input from the setting change sensor 24a to the control section 30a. In response to this, the control unit 30a inputs a table selection signal to the electronic lottery unit 39 and sets the sampled random number values to the first to sixth setting tables 41a to 41 of the first winning table 41.
It is instructed which table of f is to be matched.

The BB flag storage unit 42 is composed of a memory, and the BB flag is written every time the winning combination determination unit 40 determines BB during the normal mode. As a result, the BBs won in the normal mode game are stored and carried over. When one BB flag is read, the BB mode is entered once.

As shown in FIG. 5, the BB release lottery section 43 comprises an electronic lottery section 50, an A mode release probability table 51 and a B mode release probability table 52 which are winning combination release tables. Functions as a release lottery means. When the winning combination determination unit 40 determines the cherry,
The control unit 30a operates the electronic lottery unit 50. In the electronic lottery section 50, random number values are sampled, and the sampled random number values are collated with the A-mode release probability table 51 or the B-mode release probability table 52. In the release probability table 51 for A mode and the release probability table 52 for B mode, winning or un-winning is assigned to the grouped random number values, and the BB flag stored in the BB flag storage unit 42 by collating the random number values. Is to be released. The release probability table 51 for A mode has a higher probability of releasing the BB flag than the release probability table 52 for B mode, that is, the random number groups are grouped so that the transition to the BB mode becomes easier.
When the lottery is performed using the A mode release probability table 51, the BB release mode is the A mode, and when the lottery is performed using the B mode release probability table 52, the BB release mode is the B mode. To be done.

The BB release signal generator 44 is activated when the BB release lottery unit 43 wins the lottery. When the BB release signal generator 44 is activated, the BB release signal is input to the reel drive controller 34. In response to this,
The reel drive controller 34 has a stop button 19a.
When the BB winning design is present within the pull-in range when -19c is operated, stop control of the first to third reels 14a to 14c is performed so that the BB winning design is easily stopped on the winning effective line.

The release mode selection lottery section 45 functions as a winning combination release probability determining means, and the lottery in the BB release lottery section 43 is performed by the A mode release probability table 51 or B.
It is determined which of the mode emission probability tables 52 is used, that is, whether the BB emission mode is the A mode or the B mode. The release mode selection lottery unit 45 includes an electronic lottery unit 53, a setting 1 release mode determination table 54a which is a release probability determination table,
Setting 2 release mode determination table 54b, ..., Setting 6

, And the sampled random number values are set 1 release mode determination table 54a, set 2 release mode determination table 54b, ..., Set 6 release mode determination table 54.
It is matched with any table of f.

As shown in FIG. 6, in each discharge mode determination table, which of the A mode and the B mode is to be switched to, for example, the random number groups are grouped so as to have a ratio in each table in the figure. Has been done. The vertical axis shows the mode before transition and the horizontal axis shows the mode after transition. Settings 1, 3,
In the 5 release mode determination tables 54a, 54c, 54e, the random number values are grouped so that the A mode is likely to be shifted to the A mode, while the B mode is less likely to be shifted to the A mode. Further, in the setting 2, 4, 6 release mode determination tables 54b, 54d, 54f, the random number values are grouped so that it is easy to shift from the B mode to the A mode, but difficult to shift from the A mode to the A mode. . Therefore, fluctuations in the payout rate are large in the setting 1, 3, 5 payout mode determination tables 54a, 54c, 54e, and fluctuations in the payout rate are small in the setting 2, 4, 6 payout mode determination tables 54b, 54d, 54f. It is like this.

The replay winning probability changing unit 46 is composed of an electronic lottery unit 55, a replay winning high probability table 56, and a replay winning ultrahigh probability table 57. The electronic lottery unit 55 is activated when the winning combination determination unit 40 determines replay during a predetermined game period from the next game that is won in the lottery by the BB release lottery unit 43. The random number values sampled by the electronic lottery unit 55 are the replay winning probability table 5
6 or the replay winning ultra high probability table 57 is collated. The replay winning probability high probability table 56 and the replay winning ultra-high probability table 57 are grouped into two random value groups of winning and unwinning so as to determine whether or not reel stop control is performed so that the replay can win. The random number values are grouped so that the replay prize winning probability table 57 has a higher probability that the replay can be won than the replay winning probability table 56.

The replay winning probability lottery section 47 is activated when the lottery in the BB release lottery section 43 is won. The replay winning probability lottery unit 47 is composed of an electronic drawing unit 58 and a replay winning probability determination table 59. When the replay winning probability lottery unit 47 is activated, the electronic lottery unit 58
The random number value is sampled at, and the sampled random number value is collated with the replay winning probability determination table 59. In the replay winning probability determination table 59, the replay winning high probability table 56 and the replay winning ultrahigh probability table 57 are assigned to the random numbers grouped, and which table is to be used is determined by lottery. When the lottery is performed, the lottery result signal is sent to the control unit 30a.
Entered in. The control unit 30a causes the electronic lottery unit 55 to match the random number with the replay winning probability high table 56 or the replay winning ultrahigh probability table 57 according to the lottery result.

The medal hopper 48 pays out a specified number of payout medals to the medal tray 20 or adds the specified number to the credit counter according to the type of winning combination. A payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM area of the memory 31, and the control unit 30a reads the payout table and drives the medal hopper 48.

Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 7, when the setting of the payout rate of the slot machine 10 is started, first, the setting key 26 is inserted into the key hole 25, and

When the release lottery is not won, the sampled random number value is collated with the replay winning probability probability table 56 for a predetermined number of game periods. When the lottery by the electronic lottery unit 55 is won, the control unit 30a and the reel drive controller 34 perform stop control of the first to third reels 14a to 14c so that the replay can be won. Note that the control unit 30a and the reel drive controller 34 are set to BB during the predetermined game period from the next game in which the BB release lottery is performed.
The stop control of the first to third reels 14a to 14c is performed so that the player does not win.

As described above, since the probability that the replay can be won changes during the predetermined number of game periods after winning the BB release lottery, the BB flag of the player is released. The expectation of the game can be increased and the interest in the game can be increased. Also, when the BB release lottery is won, the replay ultra-high probability table 57 having a higher replay winning probability than the replay high probability table 56 may be used in some cases. Therefore, the more times the player wins the replay, the more frequent the player is. The expectation for the release of the BB flag is increased, and the player's expectation for the game can be further enhanced. In addition, even in the normal mode, the winning combination determination unit 4
When the replay is won by 0, whether or not the stop control of the first to third reels 14a to 14c is performed so that the replay can be won may be determined by a lottery.

It should be noted that, as a preliminary knowledge when playing the game, for example, the case 11
If a player is informed by a method such as sticking a sticker or the like on which the game method is written, or distributing a strategy booklet describing the game method of the slot machine 10 at the game hall, when the present invention is carried out. It will be more effective in giving the player a sense of tension. In addition, if the winning probability is set (for example, about 1/7) so that the replay can be easily won in the game in the normal mode, it is more effective in increasing the tension of the player.

When BB is allowed to win, the release mode selection lottery section 45 is operated. Release mode selection lottery section 45
Then, the random number is sampled by the electronic lottery section 53. The type of table for collating the sampled random number values is determined by which of the six payout rates the set payout rate is.

When the winning combination is determined using the first setting table 41a, when the winning combination is determined using the setting 1 release mode determination table 54a and the second setting table 41b When the winning combination is determined using the setting 2 release mode determination table 54b and the third setting table 41c, the winning combination is set using the setting 3 release mode determination table 54c and the fourth setting table 41d. If the winning combination is determined using the setting 4 release mode determination table 54d and the fifth setting table 41e, the setting 5 release mode determination table 54e, the sixth When the winning combination is determined using the setting table 41f, the random numbers sampled by the electronic lottery section 53 using the setting 6 release mode determination table 54f. Collation of the value is performed.

As a result, the BB release mode is determined, and the BB release lottery until the BB flag is released next time is set to the BB release determination table 51 for the A mode or the B release for the B mode.
Which of the B release determination tables 52 is used is determined. In this way, the probability of releasing the BB flag is made different for each mode, and the transition probability to each mode is made different for each payout rate. Therefore, the payout rate varies for each set payout rate. Can be increased or decreased, and the payout rate can be finely controlled.

When the BB release lottery is won and the game is played a certain number of times, the control unit 30a reads the BB flag from the BB flag storage unit 42 and the BB flag storage unit 42.
1 is subtracted from the BB flag written in
The B emission signal generator 44 is activated. The BB emission signal is output from the BB emission signal generator 44 to the reel drive controller 3
4 is input. In response to this, when the game is started and the stop buttons 19a to 19c are operated, the reel drive controller 34 causes the reel drive controller 34 to easily stop the BB winning pattern on the winning effective line.
The stop control of c is performed. Also, the reel drive controller 3
No. 4 is the first to third reels 14a when the game is started.
To 14c are rotated and the sub reel 15 is also rotated to be stopped at a position where "BB" is displayed before the operation of the stop buttons 19a to 19c is validated. This allows the player to know that BB has won the internal prize.

When the BB is won, the control section 30a reads the execution program of the BB mode from the ROM area of the memory 31 and shifts to the BB mode. In BB mode,
First, the mode is shifted to the RB introduction mode, and a game is played with 1 to 3 medal bets. Then, the game is replayed in the RB introduction mode (in the slot machine of the present embodiment, R
(Replay is substituted as a winning combination for shifting to B mode) is determined, and when this is won, it is shifted to RB mode. The game in the RB mode is played with one medal bet. The RB mode ends when a predetermined winning pattern is won eight times or when the game is played twelve times. BB mode has 3 games in RB introduction mode
The operation is ended 0 times or the RB mode is changed three times, and then the operation is ended.
