Description

  The present invention relates to a slot machine.

A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

Here, the winning is generally determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever to determine which prize group will be won or lost, and internal lottery information indicating the lottery result is generated. Here, the prize group refers to a group of one or a plurality of roles and corresponds to a lottery category. That is, a prize group and a combination may correspond one-to-one, or a plurality of combinations may correspond to one prize group.

In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid winning line, the reel stop timing is delayed, The reel is controlled so that the symbols constituting the winning combination do not stop on the valid winning line. The same applies to the combination corresponding to the prize that was not won in the internal lottery. Such control is called kicking control. On the other hand, if a prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly early, the pull-in control is performed so that the symbols constituting the role corresponding to the prize group stop on the winning line. The However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize group by internal lottery and align the winning prize group on an effective prize line. Winning any prize group in the internal lottery is called winning, and not winning any prize group is called losing. And
The fact that a symbol stopped on the winning line constitutes a winning combination is called winning, and the non-winning is not constituted. In non-winning cases, when the internal lottery result is lost, even if the internal lottery is won, the operation timing of the reel stop button is greatly shifted, so that the role corresponding to the winning prize is not established, so-called Includes missing items.

Such a slot machine can execute a plurality of types of games such as a big bonus game and a regular bonus game in addition to the normal game. The transition from the regular game to the big bonus game is conditional on winning the BB prize, and the transition to the regular bonus game is R
Subject to B prize winning. The internal lottery described above is executed for each game, and the internal lottery result is usually not carried over to the next game. (See, for example, Patent Document 1).

The RB game ends when the JAC game is played 12 times or a maximum of 8 times is won. JAC
The game is played by betting one medal and enabling only the central winning line. JA
In the C game, the JAC Award is adopted. When winning the JAC Award, the slot machine usually pays out 15 medals. The big bonus game has a higher probability of winning the RB prize than the normal game.

By the way, since the conventional big bonus game is continued until the RB prize is won three times or the game is thirty times, the medals are paid out in the period. For this reason, there is a concern that the player may be jealous. Therefore, it is conceivable to set an upper limit on the number of medals that can be obtained in one big bonus game. Here, when the maximum value of the acquired number is the maximum acquired number, payout exceeding the maximum acquired number is prohibited.

There is a problem that if a prize with a large payout number is won in a state where the current acquired number is approaching the maximum acquired number, the maximum acquired number will be exceeded. For example, if you win the RB award during the big bonus game, the regular bonus game will start. During the regular bonus, the winning probability of the JAC award is set high. When the acquired number approaches the maximum acquired number, the possibility of exceeding the maximum acquired number in the next game is extremely high. Furthermore, if the current winning number approaches the maximum acquired number by winning the RB award during the big bonus, the next game will be a jack game and the possibility of exceeding the maximum acquired number is very high.

In addition, as described above, winnings are generally prohibited except for prizes won in the internal lottery, but for at least one reel, a game for stopping reels can be executed regardless of the result of the internal lottery. Slot machines are known. Such a game is referred to as a free bonus game in this specification. In order to shift from the normal game to the free bonus game, a game with a higher probability of winning the predetermined prize in the internal lottery than the normal game, on condition that a predetermined prize (hereinafter referred to as FB prize) is won. There is also a demand to realize it. Such a game is referred to herein as a challenge bonus game. In the challenge bonus game, just like the big bonus game,
It is preferable to set a limit on the maximum number obtained. In this case, as in the big bonus game, there is a problem that if the current winning number is approaching the maximum acquired number and a prize with a large payout number is won, the maximum acquired number will be exceeded. In addition, if the FB prize is won during the challenge bonus game, the game shifts to the free bonus game. In the free bonus game, the reel stop button is operated for a desired symbol regardless of the result of the internal lottery, and a high dividend is won. Therefore, when the current acquisition number approaches the maximum acquisition number by winning the FB prize, there is a very high possibility that the maximum acquisition number will be exceeded in the next game.

The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a slot machine that adjusts the number of payouts so as not to exceed the maximum obtained number.

The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

A specific game start prize is included, the specific game can be executed over a plurality of games, and the total number of the game media to be paid out during the period from the start to the end of the specific game is limited by a predetermined amount. In the slot machine that transitions the game state from the specific game to the normal game when a predetermined end condition is satisfied, the winning probability of the special game start prize in the specific game is determined as the special game start prize in the normal game. A lottery means (3) for generating a lottery information (ISD) indicative of a winning prize or a lost prize, which is determined by lottery from among a plurality of prizes and loses, is set higher than the winning probability of
1, 33), and when the lottery information (ISD) indicates a winning prize, a set of symbols corresponding to the winning prize is allowed to stop on the activated winning line (L1-L5), When a set of symbols corresponding to a prize other than the winning prize is prohibited from stopping on the activated winning line (L1-L5) and the lottery information (ISD) indicates a loss, Stop control means (31) for stopping variable display of the plurality of display rows (R1-R3) so as to prohibit the corresponding symbol set from stopping on the activated pay line (L1-L5); , Winning determination means (31) for determining a winning according to the combination of symbols stopped on the activated winning line (L1-L5), and paying out the number of the game media according to the winning prize The payout means (31) to be issued and the specific game An acquired quantity calculating means (31, 34) for calculating the paid-out quantity of the game medium and calculating an acquired quantity; a comparing means for comparing the acquired quantity with a reference quantity less than the predetermined quantity; Game state management means (31) for ending the specific game in the current game and shifting the game state from the next game to the normal game when the acquired quantity exceeds the reference quantity with reference to a comparison result And.

According to the present invention, in the special game, when the acquired number exceeds the reference quantity that is smaller than the predetermined quantity, the special game is ended. Therefore, the specific game can be ended before the acquired number exceeds the predetermined quantity. As a result, a large amount of game media will not be paid out in the specific game, and the game of the slot machine will not mischief the player. Here, the game medium includes pachinko balls in addition to medals used for games (game medals). Further, the payout of the game medium includes storing the game medium as a credit in addition to discharging the game medium from the slot machine, or recording it on a recording medium by an electromagnetic method.

<3: Electrical configuration of slot machine>
FIG. 5 is a block diagram showing a control device that controls the game processing operation in the slot machine 1 and a circuit configuration including peripheral devices related to the present invention among those constituting the slot machine 1.

The control device includes main board 30A and sub board 30B as main components. The main board 30A includes a CPU 31, a clock generation circuit 32, a sequence generation circuit 33, a RAM 34, and a ROM.
35, a transmission timing control circuit 36, a data transmission circuit 37, an input port 38 and an output port 39.

The CPU 31 is connected to each component of the main board 30A excluding the transmission timing control circuit 36 via a bus (not shown). The CPU 31 executes the first control program CP1 and controls each component. The first control program CP1 describes how to operate the entire slot machine 1. For this reason, the CPU 31 uses the slot machine 1
Acts as a control center for The clock generation circuit 32 includes an oscillation circuit including a crystal resonator, generates a reference clock signal CLK having a fixed period, and supplies the reference clock signal CLK to the CPU 31 and the number sequence generation circuit 33.

The sequence generator 33 is composed of a high-speed ring counter and a reference clock signal CL.
K is counted to generate count data CD. The numerical value range of the count data CD is, for example, 0 to 65535, depending on the contents stored in the prize group lottery table TBL1 described later.
The count data CD can be input to the CPU 31 via the input port.
1 detects the timing at which the player depresses the start lever 6 and reads the count data CD through the input port at the timing to generate sampling data SD.

Since the player cannot know the value of the count data CD, the timing at which the start lever 6 is pushed down by the player is random. Therefore, the value of the sampling data SD is equivalent to a value sampled from a random number. In addition,
Since the sequence generator 33 operates in synchronization with the reference clock signal CLK, the count data C
The period of D is extremely short. For example, if the frequency of the reference clock signal CLK is 30 MHz, the time required for the value of the count data CD to change from “0” to “65535” is
2.2 msec. Therefore, the count data C can be obtained by an unauthorized means.
Even if the value of D can be known, it is impossible to cause the CPU 31 to generate sampling data SD having a desired value by operating the start lever 6.

Next, the RAM 34 functions as a work area of the CPU 31 and stores intermediate results of arithmetic processing, data generated as necessary, flags used for various controls, and the like. For example, internal lottery data ISD indicating the result of the internal lottery is stored in the RAM 34.

In addition to the first control program CP1, the ROM 35 stores a prize group lottery table group TBL1, a stop table group TBL2, a winning symbol combination table TBL3, and the like. In the winning symbol combination table TBL3, combinations of winning symbol combinations and medal payout numbers for winning combinations are stored in association with each other.

Since the control of the slot machine 1 requires control according to the difference in game value, it is convenient to classify various roles by paying attention to the game value. In the slot machine 1 of this embodiment, one prize group is assigned to each winning combination, but one or more winning combinations may be assigned to one winning group.

Next, the prize group lottery table group TBL1 includes a plurality of prize group lottery tables. CPU31 performs internal lottery using the prize group lottery table selected according to the kind of game. As prize group lottery tables, tables used for normal games, tables used for BB games,
A table used for the RB game, a table used for the CB game, and a table used for the FB game are prepared.

FIG. 6 shows the contents stored in the base game prize group lottery table TBL11. As shown in this figure, the prize group lottery table TBL11 stores lottery division data in the first to ninth storage areas ADR1 to ADR9, respectively. The value of the lottery category data indicates the width of the lottery category corresponding to each prize group. For example, the lottery classification data stored in the first storage area ADR1 corresponds to the loss, and the value is “59536”. The lottery classification data stored in the ninth storage area ADR9 corresponds to the BB prize, and its value is “200”.

FIG. 7 is a flowchart showing the operation of the CPU 31 in the internal lottery process using the prize group lottery table TBL11. First, the CPU 31 performs an initialization process (step S1).
Specifically, the value of the variable N is reset to “0” and the value stored in the internal register is reset to “0”.

Next, the CPU 31 stores the sampling data SD in the internal register (step S2
Subsequently, the value of the variable N is changed to N + 1 (step S3). After this, CPU3
1 reads lottery classification data from the Nth storage area (step S4). In the process immediately after the initialization process, since the value of the variable N is “1”, the lottery classification data is read from the first storage area ADR1. The value in this case is “59536”.

Next, the CPU 31 reads the stored contents of the internal register, adds the read data value and the lottery classification data value, and stores the added value in the internal register (step S5). As a result, the content stored in the internal register is updated from the original data value to the added value.

Next, the CPU 31 determines whether or not the added value is greater than or equal to the reference value (step S6).
The reference value is equal to the sum of the values of the lottery classification data stored in the first to ninth storage areas ADR1 to ADR9.

When the added value is less than the reference value, the CPU 31 returns the process to step S3, and repeats the processing from step S3 to step S6 until the added value becomes equal to or greater than the reference value. When the added value is equal to or greater than the reference value, the CPU 31 advances the process to step S7, determines a prize group according to the value of the variable N, and generates internal lottery data ISD. Specifically, when N = 1, it is lost, and N = 2
Replay Award, N = 3 Cherry Award, N = 4 Bell Award, N = 5 Single F
It is determined that the B prize, the watermelon prize when N = 6, the CB prize when N = 7, the RB prize when N = 8, and the BB prize when N = 9 are won. As a result, as shown in FIG. 6, the correspondence between the sampling data SD and the prize group is lost at SD = 65535-6000, replay prize at SD = 5999-4300, cherry prize at SD = 4299-3300, SD = 3299 to 2400 for the Bell Award, SD = 2399 to 1600 for the Single FB Award, SD = 1599 to 900 for the Watermelon Award, SD = 899 to 500 for the CB Award, SD = 499 to 200 for the RB Award , SD = 19
9-0 correspond to each BB prize.

Then, the CPU 31 generates internal lottery data ISD based on the determination result. The internal lottery data ISD includes a BB award for the first bit, an RB award for the second bit, a CB award for the third bit,
A bell prize is assigned to the fourth bit, a watermelon prize is assigned to the fifth bit, a cherry prize is assigned to the sixth bit, a replay prize is assigned to the seventh bit, and a single FB prize is assigned to the eighth bit. If any prize is won by internal lottery, the CPU 31 sets the value of the corresponding bit to “1”, otherwise sets the value of the bit to “0”. Therefore, by referring to the internal lottery data ISD, it is possible to know whether the player has won or lost, and the winning group that has been won.

In the following description, the first bit of the internal lottery data ISD is called a BB winning flag, the second bit is called an RB winning flag, and the third bit is called a CB winning flag. Each flag is set to “1”.
Setting to "0" is called "clearing". With regard to a small role, even if a game is won by an internal lottery, no medal is paid out unless the game is won. However, for the RB prize, the BB prize, and the CB prize, if a prize is won in an internal lottery of a game, the BB prize flag, the RB prize flag, and the CB prize flag are not cleared without winning in the game. The BB winning flag, the RB winning flag, and the CB winning flag are maintained until winning in the game. This is called carrying over the winning flag. As described above, the internal lottery is executed for each game, and the internal lottery data ISD is generated.
Except for winning the B and CB prizes, it is valid only in the game. Thus, even if the winning flag is carried over, the internal lottery is executed for each game. For example, when the watermelon prize is won in the internal lottery in the game in which the winning flag of the BB prize is carried over, the internal lottery data ISD In this state, the values of the first bit and the fifth bit are set to “1”. In addition, if neither game is won in this game, only the fifth bit is “0”.
Is cleared to "1" and the first bit remains set to "1".

Next, the stop table group TBL2 is composed of a plurality of stop tables. In each stop table, a symbol number PN (symbol number at the reference position) displayed on the central winning line L1 and advancing frame number data indicating the advancing frame number (moving symbol number) are stored in association with each other. . Here, the advance frame number means that each player has left, middle and right reel stop buttons 7a,
This refers to the number of symbols that go from 7b and 7c down to when each of the left, middle, and right reels R1, R2, and R3 stops.

Since each of the left, middle, and right reels R1, R2, and R3 rotates at high speed, even if the player operates the stop button aiming at a specific symbol, skill is required to stop the desired symbol. There are individual differences in the mastery of the stop button operation. In particular, it is difficult for a player with low moving eyesight to stop a desired symbol. On the other hand, a highly skilled player can operate the stop button when a desired symbol is displayed on the winning line.

However, in order for low-skilled players to enjoy the game, it is necessary to make the symbols easy to some extent. On the other hand, if the result of the internal lottery is lost, it is necessary to control the rotation of the reels so that the combination is not established There is. The stop table is used to control such reel rotation. The stop positions of the left, middle, and right reels R1, R2, and R3 are determined with reference to the stop table.

Returning to FIG. 5, the description will be continued. The transmission timing control circuit 36 and the data transmission circuit 37 shown in the figure transmit to the sub-board 30B information on the type of combination determined by the internal lottery and the stop table selected corresponding to the combination. The sub-board 30B is responsible for processing for notifying the player of predetermined information.

Next, the input port 38 is an input interface for signals supplied from various sensors described later. On the other hand, the output port 39 is an output interface for supplying control signals to each motor and various devices.

The main input signal generating means connected to the input port 38 and generating various input signals includes the following. The inserted medal detection sensor 41 detects a medal inserted through the medal slot 5 and generates one output pulse for one medal. Therefore,
The CPU 31 can detect the number of medals inserted by counting the output pulses.

The BET button sensor 42 detects the operation of the BET button 15. The start lever sensor 43 detects the operation of the start lever 6 and outputs a start operation signal 43a. The left / middle / right reel stop button sensors 44, 45, 46 are the left / middle / right reel stop buttons 7a, 7
The operations b and 7c are detected and stop operation signals 44a, 45a and 46a are output. The left / middle / right reel position detection sensors 47, 48, 49 are connected to the left / middle / right reels R1, R2, R3.
Are detected, and detection signals 47a, 48b, and 49c are generated. The CPU 31 detects these signals to detect the operation timing of the start lever 6, the reel stop button 7a,
The operation timings 7b and 7c and the rotation positions of the reels R1, R2, and R3 are acquired.

The right reel position detection sensor 49 includes a photocoupler 492, an amplifier, and the like shown in FIGS.
And a comparator. The photocoupler 492 includes a light emitting unit and a light receiving unit. When the light receiving unit outputs a light reception signal at a level corresponding to the amount of light received, the amplifier amplifies the light reception signal. The comparator compares the output signal of the amplifier with a predetermined threshold value, generates a detection signal 49a, and outputs this as an output signal of the right reel position detection sensor 49. When the right reel R3 rotates, the light shielding piece 491 shown in FIG. 2 passes through the photocoupler 492 once per rotation. Therefore, the rotation position of the right reel R3 can be detected by the detection signal 49a. The left / middle position detection sensors 47 and 48 are configured in the same manner as the right reel position detection sensor 49.

The main means connected to the output port 39 and receiving various output signals is the left
There are middle and right reel drive motors 51, 52 and 53. Left / middle / right reel drive motors 51, 5
Reference numerals 2 and 53 denote motors that respectively rotate the left, middle, and right reels R1, R2, and R3. In this example, the motors include stepping motors. Therefore, the CPU 31 supplies the drive signals 51, 52a, 53 to the left / middle / right reel drive motors 51, 52, 53.
By adjusting the number of pulses a, the stop positions of the left, middle and right reels R1, R2, and R3 can be accurately determined.

Each of the motors 51, 52, and 53 is configured to rotate once by 400 pulses. As described above, 21 symbols are formed on each of the reels R1, R2, and R3. Of these, 20 symbols advance by 1 pulse with 19 pulses, and 1 symbol advances by 1 pulse with 20 pulses. Further, the CPU 31 counts the number of pulses supplied to each of the motors 51, 52, 53, and holds the count result as each position data MD1, MD2, MD3. The values of the position data MD1, MD2, and MD3 are reset when the detection signals 47a, 48a, and 49a become active.

FIG. 8 is a timing chart showing the relationship between the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3. As shown in this figure, when the detection signal 49a rises from the low level to the high level at time t1, the value of the position data MD3 is reset. Time t1 is timing when the light shielding piece 491 shown in FIG. 3 passes through the photocoupler 492. At this time, the rotation position of the right reel R3 is the symbol (B) of the symbol number PN = 1 shown in FIG.
AR) is displayed in the middle of the display window 4c. In other words, the mounting position of the light shielding piece 491 and the photocoupler 492 is determined so that the symbol is displayed in the middle of the display window 4c.

When 20 pulses are supplied to the right reel drive motor 53 as the drive signal 53a during the period from time t1 to time t2, the right reel drive motor 53 rotates the right reel R3 by 1/21. As a result, the symbol (cherry) of symbol number PN = 2 shown in FIG. 4 is displayed in the middle of the display window 4c. Thereafter, the symbols are sequentially displayed in the same manner, and when the time t3 is reached, the right reel R3 rotates once and the symbol (BAR) of the symbol number PN = 1 is displayed again. Thus, the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD
Since 3 is closely related, the CPU 31 can detect the display state of the symbol based on the position data MD3.

Note that the left reel R1 and the middle reel R2 are similar to the right reel R3 described above.
The PU 31 can detect the display state of the symbols based on the position data MD1 and MD2.

FIG. 9 shows an example of the stop table. This stop table is used for drawing a plum symbol into the winning line L1. For example, when the player depresses the left reel stop button 7a, the stop operation signal 44a becomes active. The CPU 31 detects this and acquires the symbol number PN. At this time, it is assumed that the symbol number PN is “12”. In this case, the white 7 symbol is approaching the winning line L1. The CPU 31 obtains the acquired symbol number P.
The number of moving frames corresponding to N = 12 is read from the stop table shown on the left in FIG. 9, and the number of moving frames “2” is acquired. Thereafter, the CPU 31 moves the left reel R1 by two frames and stops it.
That is, the plum symbol positioned two frames above the symbol of white 7 is drawn into the winning line L1 and stopped.

Each stop table shown in FIG. 9 has “0” as the number of moving frames at the location corresponding to the plum symbol.
Is recorded. A moving frame number of “0” means that not only the symbol stops at the moment of stop operation, but also moves within the range of less than one symbol from the moment of stop operation and the center position of the symbol overlaps the winning line. Specifically, as shown in FIG. 10A, when the center position Q of the plum symbol is before the activated pay line L1 when the reel stop button is operated, the plum symbol The reel rotates and stops so that the center position Q overlaps the activated pay line L1. On the other hand, when the reel stop button is operated as shown in FIG. 5B, if the center position Q of the plum symbol has gone too far from the activated pay line L1, the bell symbol which is the next symbol is displayed. The reel rotates and stops so as to stop at the winning line L1 for which is enabled. Accordingly, when the number of moving frames is “0”, the symbol immediately before reaching the winning line is stopped on the winning line L1 by the rotation of the reel.

Next, the sub-board 30B includes a CPU, a data input circuit, a clock generation circuit, ROM, RA
M and a liquid crystal display control circuit 60 are provided, and various effects are displayed on the liquid crystal display device 64. The sub-board 30 </ b> B controls turning on / off the left / middle / right backlights 65 to 67 and emits sound effects from the speaker 68.

The CPU of the sub board 30B receives various commands transmitted from the main board 30A. This command includes internal lottery data ISD and the like. Based on the BB winning flag or CB winning flag of the internal lottery data, the CPU displays an animation or a character on the liquid crystal display device 64 in order to notify the player that the BB prize or CB prize has been won. In addition, a predetermined sound is emitted from the speaker 68 when the start lever 6 is operated.

<4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. 11 and 12 are flowcharts showing the operation of the CPU 31 controlling the slot machine 1 from the start to the end of one game.
One game period is a period from when a bet operation is accepted until the next bet operation is accepted.

The CPU 31 determines whether or not the player has made a bet operation based on detection signals from the inserted medal detection sensor 41 and the BET button sensor 42 (step S11). Proceed to S12.

In step S <b> 12, the CPU 31 determines whether the player has operated the start lever 6 based on the detection signal of the start lever sensor 43. When the player operates the start lever 6, the CPU 31 performs a process for prohibiting the betting operation (step S).
13). If the bet operation is prohibited, even if the player inserts a medal or operates the BET button 15 during the period until the prohibition is canceled, the acceptance is rejected.

Next, the CPU 31 sets a prize group lottery table corresponding to the game mode (step S1).
4). Specifically, from the prize group lottery table group TBL1, the base game, the RB game, and the B
A table corresponding to the type of game such as B game, CB game, and FB game is selected. In this case, the CPU 31 refers to the RB game flag, the BB game flag, the CB game flag, and the like stored in the RAM 34, identifies the game type of the game, and selects a table based on the result.

In the internal lottery of the FB game, there are the following two modes. In the first aspect, winning or losing is determined by lottery. However, it is preferable to make the lottery probabilities different between the FB in CB and the single FB (FB game in the normal game). In the second aspect, the internal lottery is not executed.

Next, the CPU 31 executes an internal lottery process using the prize group lottery table TBL1 set in step S14 (step S15). That is, the type of prize group lottery table TBL1 also changes according to the type of game. Thereafter, based on the flag (management information) indicating the type of game, the CPU 31 performs the normal game, the BB game, the CB game, the RB game, and the FB
It is determined that the game is in progress (step S16). When it is determined that the game is the normal game, the BB game, or the CB game, the CPU 31 advances the process to step S17, and executes a winning flag setting process. The contents of the winning flag setting process are shown. Specifically, as described with reference to FIG. 7, first, the CPU 31 samples the count data CD and obtains the sampling data SD at the timing when the detection signal of the start lever sensor 43 becomes active. To do. Secondly, the CPU 31 refers to the prize group lottery table and sets a winning flag. The BB game or CB game is different from the normal game in the winning probability of the RB prize or the FB prize, but the type of prize adopted is the same as that of the normal game. Accordingly, the winning flag setting process is the same for the base game, the BB game, and the CB game.

If it is determined in step S16 that the game is a normal game, a BB game, or a CB game, the CPU 31 advances the process to step S17, and performs the process of setting a winning flag in the normal game, the BB game, or the CB game shown in FIG. Execute. CPU31 is BB
It is determined whether or not it is won (step S70). If it is won, the BB winning flag is set (step S71). If the BB prize is not won, the process proceeds to step S72. Next, CPU
31 determines whether or not the CB is won (step S72). If the CB is won, the CB winning flag is set (step S73). If the CB prize is not won, the process proceeds to step S74.
Next, the CPU 31 determines whether or not it is a single RB win (step S74), and if it is a win, sets a single RB win flag (step S75). Proceed to Next, the CPU 31 determines whether or not the BB winning RB is won (step S76), and if the winning is the BB winning RB winning flag (step S77), the BB is set.
If the medium RB is unsuccessful, the process proceeds to step S78. Next, the CPU 31 is a single FB
It is determined whether or not the winning combination has been won (step S78). If the winning combination has been won, a single FB winning flag is set (step S79). If the single FB prize has not been winning, the process proceeds to step S80. Next, the CPU 31 determines whether or not the CB FB is won (step S80).
The FB winning flag during B is set (step S81), and if the FB during CB is not winning, the process proceeds to step S82. Next, the CPU 31 determines whether or not the bell is won (step S8).
2) If the player wins, the bell winning flag is set (step S83). If the bell award is not selected, the process proceeds to step S84. Next, the CPU 31 determines whether or not the watermelon is won (step S84). If the watermelon is won, a watermelon winning flag is set (step S85).
If the watermelon prize is not selected, the process proceeds to step S85. Next, the CPU 31 determines whether or not the cherry is won (step S86). If the cherry is won, a cherry winning flag is set (step S87). If the cherry award is not won, the process proceeds to step S88. Next, the CPU 31 determines whether or not it is a replay winning (step S88), and if it is winning, sets a replay winning flag (step S89).

Next, if it is determined in step S16 shown in FIG.
PU31 advances a process to step S18 and performs a winning flag set process. Specifically, the CPU 31 determines whether or not the JAC is won, and if the JAC prize is won,
If the AC winning flag is set, but the JAC prize is not selected, the process ends without setting the JAC winning flag.

Next, when it is determined in step S16 that the FB game is in progress, the CPU 31
The process proceeds to step S19 to execute a winning flag set process. When the internal lottery is the first mode described above, the CPU 31 determines whether or not it is a win.
While the small combination flag is set, in the case of a loss, the processing is ended without setting the FB small combination flag. In the internal lottery, it is different from the normal game or the CB game in which only a winning or a lost game is drawn. On the other hand, when the internal lottery is the second mode described above, the internal lottery itself is not executed. In this case, the winning flag is always set during the FB game. Further, an FB prize lottery may be executed during the FB game.

Next, in step S20 shown in FIG. 11, a reel stop data group selection process is executed based on the winning flag of the base game, BB game, or CB game set in step S17. FIG. 17 shows the processing contents of reel stop data group selection in the base game, BB game, or CB game. The CPU 31 refers to the winning flag of the internal lottery data ISD, and replays a winning flag, a watermelon winning flag, a bell winning flag, a cherry winning flag, a BB winning flag, a CB winning flag, a single RB winning flag, and an BB winning RB winning flag. Are sequentially determined (steps S90 to S97). And
If the replay winning flag is set, the CPU 31 selects the replay stop data group (step S98). If the watermelon winning flag is selected, the CPU 31 selects the watermelon stop data group (step S99), and the bell winning flag. Is set (step S100), if the cherry winning flag is set, the cherry stopping data group is selected (step S101), and if the BB winning flag is set. A BB stop data group is selected (step S102). If the CB winning flag is set, the CB stop data group is selected (step S103). If the single RB winning flag is set, the single RB stop data is set. Select a group (step S104), and if the BB winning RB winning flag is set, stop for RB during BB Selecting over data group (step S105).

Next, in step S21 shown in FIG. 11, a reel stop data group selection process is executed based on the winning flag of the RB game set in step S18. The CPU 31 refers to the winning flag of the internal lottery data ISD and determines whether or not the JAC winning flag is set. If the JAC winning flag is set, the CPU 31
A stop data group for C is selected. If the JAC winning flag is not set, stop data for non-winning is selected. Here, the stop data group for JAC is set so that the plum symbol can be drawn into the central winning line L1 as shown in FIG. More specifically, the CPU 31
At the timing when the stop operation signals 44a to 46a are detected, the plum symbol is the winning line L
The reels R1 to R3 are controlled so that the plum symbol is drawn onto the winning line L1 and stopped when the number is within a predetermined number of moving symbols from 1. In the JAC game, only one bet is allowed, so the winning line L1 is an activated winning line. In this example, the number of moving symbols is set to “4”. Accordingly, a plum symbol in the range of 0 frame to 4 frames is drawn into the winning line L1.

Next, in step S22 shown in FIG. 11, a reel stop data group selection process is executed based on the winning flag of the FB game set in step S19. The CPU 31 refers to the winning flag of the internal lottery data ISD and determines whether or not the winning flag for the FB prize is set. If the FB winning flag is set, the CPU 31 determines that the FB
The stop data group for use is selected, and if the FB winning flag is not set, the stop data group for small role is selected. Here, the FB stop data group is set so that the plum symbol can be drawn into the activated pay line. More specifically, the CPU 31 performs a stop operation signal 44a to 44a.
When the 46a is detected, the reels R1 to R3 are drawn so that the plum symbol is drawn onto the activated winning line and stopped when the plum symbol is within a predetermined number of moving symbols from the activated winning line. Is controlled. In addition, the small combination stop data group is set so that the plum symbol is not stopped on the activated pay line in the third stop.

The FB game may be a single bet game or a multiple bet game.
In the former case, it is preferable that the FB stop data group is also used as the JAC stop data group in the RB game. On the other hand, in the latter case, the FB stop data group is preferably used also as the replay stop data group in the base game. In these cases, the predetermined number of moving symbols is set to “4”. Thus, by combining the stop data group between different types of games, the number of stop tables can be reduced and the data capacity of the ROM 35 can be reduced.

As for the arrangement of the plum symbols constituting the plum role of the FB prize, as shown in FIG. 4, the distance between the most separated plum symbols is 5 symbols. Accordingly, by setting the predetermined number of moving symbols to “4” as described above, the reel stop buttons 7a to 7 can be played at any timing by the player.
Even if c is operated, the plum symbol can be drawn on the activated pay line. In this example, the plum symbol is adopted for the FB prize, but a plurality of types of symbols may be adopted. In this case, it is preferable that the symbol arrangement on the reel is set so that a predetermined number of moving symbols such as a bell symbol can be drawn on the winning line.

Returning to FIG. When the selection of the reel stop data group is completed, the CPU
31 sets each reel driving flav which indicates that the reel is rotating, starts the rotation of the reel (step S23), and executes a reel rotation stop process (step S24). The reel rotation stop process will be described later.

Next, the CPU 31 determines that the game type is normal game, BB game, CB game, R
It is determined whether the B game is being played or the FB game is being played (step S25 shown in FIG. 12). If the CPU 31 is a normal game, BB game, or CB game, the process proceeds to step S2.
If the game is an RB game, the process proceeds to step S27. If the game is an FB game, the process proceeds to step S28 to execute a winning determination process. The winning determination process for each game will be described later.

In the slot machine 1 of the present embodiment, the number of medals that a player can acquire is limited for the BB game and the CB game. In the following description, the upper limit of the acquired number in the BB game is referred to as the maximum acquired number MAXbb, and the upper limit of the acquired number in the CB game is referred to as the maximum acquired number MAXcb. In the present embodiment, the maximum acquired number MAXb
b and MAXcb are set according to the payout rate. Here, the payout rate refers to the ratio of the total number of medals paid out to the total number of medals inserted within a predetermined number of games in the past. The former is called the total number of medals IN, and the latter is called the total number of medals OUT. Step S30
The medal IN number counting process is for calculating the total medal IN number, the medal OUT number counting process shown in step S31 is a total medal OUT number calculating process, and the game number counting process in step S29 is a step. This is a process of counting the number of games necessary for the processes of S30 and S31.

FIG. 13 shows the contents of the game count processing. First, the CPU 31 increments the count value of the game counter by “1” (step S40), and determines whether or not the count value of the game counter is equal to “400” (step S41). And the count value is “4”
If it is “00”, the CPU 31 clears the count value of the game counter and returns it to “0” (step S42). On the other hand, if the count value of the game counter is less than 400, step S4
The process of No. 2 is finished and the game number counting process is finished. Therefore, the count value of the game counter circulates from “0” to “399”. “400”, which is the determination criterion in step S41, is set to be the number of games in the past that is the basis for calculating the payout rate. In this example, the payout rate is calculated based on the game results of the past 400 games. In addition, a dedicated ring counter may be provided as a game counter, but in this example, this is realized by a program. In this case, a predetermined storage area of the RAM 34 is used as a game counter, and the count value of the game counter stored in the storage area is updated for each game.

FIG. 14 shows the processing contents of the medal IN number counting process and the medal OUT number counting process. As shown in the figure, these processes proceed while reading / writing data from / to a predetermined storage area of the RAM 34. The RAM 34 has a storage area 341 for storing the total IN number, a storage area 342 for storing the count value of the game counter, a storage area 343 for storing the number of inserted medals IN and the number of paid-out medals OUT in each of the past 400 games, and A storage area 344 for storing the total OUT number is provided.

FIG. 15 shows a detailed configuration of the storage area 343. The storage area 343 is configured as a so-called ring buffer. In one stage of the ring buffer, 8-bit data is stored, IN data indicating the number of inserted sheets is stored from the 0th bit b0 to the third bit b3, and from the fourth bit b4. O indicating the number of payouts up to the seventh bit b7
UT data is stored. Each storage area of the ring buffer is associated with the count value of the game counter. In this example, the addresses of 400 storage areas are 2000H to 21
It is assigned up to 8FH, so that the lower bits of the address match the count value of the game counter. Therefore, it is possible to immediately generate a buffer pointer indicating the ring buffer address from the count value of the game counter.

In the medal IN number counting process shown in FIG. 14, the CPU 31 determines whether or not the game is a replay game (step S50), and if the replay prize is won, the number of insertions is set to “0” (step S51). Then, the process proceeds to step S52. On the other hand, when the replay prize is not won, the CPU 31 omits the process of step S51 and advances the process to step S52.

In step S <b> 52, the CPU 31 adds the new insertion number, which is the number of medals inserted in the game, to the total IN number read from the storage area 341, and writes this in the storage area 341. Thereby, the total IN number is updated. Next, the CPU 31 reads out the count value of the game counter from the storage area 342, and calculates a buffer pointer based on the count value (step S53).

Next, the CPU 31 reads and acquires the old inserted number stored in the storage area indicated by the buffer pointer (step S54), and writes the new inserted number in the storage area (step S55). Subsequently, the CPU 31 updates the total IN number by subtracting the old insertion number from the total IN number (step S56).

Next, the medal OUT number counting process will be described with reference to FIG. The CPU 31
First, the storage area 344 of the RAM 34 is accessed, the total OUT number is read, the new payout number is added to this, and this is written in the storage area 344 (step S60). Next, CPU
31 reads the count value of the game counter from the storage area 342, and calculates a buffer pointer based on the count value (step S61).

Next, the CPU 31 reads and acquires the old payout number stored in the storage area indicated by the buffer pointer (step S62), and writes the new payout number in the storage area (step S63). Subsequently, the CPU 31 subtracts the old payout number from the total OUT number,
This is written in the storage area 344 to update the total OUT number (step S64).

Returning to FIG. When the above-described medal OUT number counting process is completed, the CPU 31 determines whether or not the replay prize has been won by comparing with a plum combination that is a combination of the symbols on the activated line of each reel and the symbol of the replay prize. (Step S32). When winning the replay prize, the same winning line as the winning line activated in the previous game is automatically activated without performing a betting operation. Therefore, if the replay prize is won, the process returns to step S12. Thereafter, the CPU 31 executes a one-game end process (step S33) and cancels the prohibition of the betting operation (step S34).

FIG. 18 is a flowchart showing the processing contents of the reel rotation stop processing (step S26). First, the CPU 31 indicates whether or not the first button stop operation has been performed, based on the stop operation signal 4.
A determination is made based on 4a to 46a (step S120).

When the first stop operation of the reel stop button is detected, the CPU 31 acquires the stop button number (button type) of the currently pressed reel stop buttons 7a to 7c (step S121), and the pattern immediately after the stop operation is obtained. The number PN is acquired (step S122). Specifically, the CPU 31 detects the timing at which the reel stop buttons 7a, 7b, and 7c are pressed based on the stop operation signals 44a to 46a from the reel stop button sensors 44 to 46, and the symbol number PN at the timing. To get. In this example, the stop button number “1” is assigned to the reel stop button 7 a and the stop button number “1” is assigned to the reel stop button 7 b.
2 ”and the stop button number“ 3 ”are respectively assigned to the reel stop buttons 7c.

Next, the CPU 31 selects, based on the internal lottery data ISD, stop button number, symbol number PN, etc., from the stop data table group selected in steps S20 to S22.
The stop data table group which can be used is limited (step S124), and the combination of stop data tables according to the stop operation order is specified. When there are a plurality of combinations, the CPU 31 specifies a combination of stop tables to be used by lottery or the like. When there are not a plurality of combinations, the combinations are specified. Thereby, the CPU 31 determines one stop data table used for the first stop of the reel. (Step S125)

Next, the CPU 31 acquires the advance frame number (moving symbol number) corresponding to the symbol number from the determined stop table (step S126), and then stops the reel that has been stopped based on the advance frame number. (Step S127).

Next, the CPU 31 determines whether or not there has been a second button stop operation, and indicates whether or not the stop operation signal 44a.
To 46a (step 128), if there is a second button stop operation, stop button number acquisition (step S129), symbol number acquisition (step S130), combination of stop table specified in step S124 The stop table corresponding to the second stop of the reel is determined (step S131), the number of advance frames is acquired (step S132), and the reel stop (step S133) is executed. Thereafter, the CPU 31 determines whether or not the third button stop operation has been performed based on the stop operation signals 44a to 46a (step S).
134) When there is a third button stop operation, the stop button number is acquired (step S135).
), Obtaining a symbol number (step S136), and determining a stop table corresponding to the third stop of the reel from the combination of stop tables specified in step S124 (step S13).
7) The advance frame number is acquired (step S138), and the reel stop (step S139) is executed. As described above, the CPU 31 selects a stop table used for stop control from among a plurality of stop tables according to the type of game, the result of the internal lottery, and the order of the stop operation of the reel stop button. When the internal lottery data (lottery information) indicates winning, the CPU 31 that executes the reel stop control process described above allows the symbol set corresponding to the winning prize to stop on the activated winning line, When a set of symbols corresponding to a prize other than the winning prize is prohibited from being stopped on the activated winning line, and the internal lottery data (lottery information) indicates a loss, the set of symbols corresponding to all prizes Functions as stop control means for stopping the variable display of each reel (a plurality of display columns) so as to prohibit the stop on the pay line in which is activated.

Next, the winning determination process of the base game, BB game, or CB game described above with reference to FIG. 19 will be described. In this process, by comparing the symbols on each active line of each stopped reel with the combination of symbols assigned to each award, it is sequentially determined whether or not a watermelon, bell, or cherry award was won. A determination is made (steps S140 to S142), and each part is controlled so as to pay out the number of medals corresponding to the winning prize with reference to the winning symbol combination table TBL3 (steps S143 to S145).

Next, the CPU 31 determines whether or not it is a single RB win (step S146), and if it is a single RB win, the payout of medals is executed (step S147), and the RB game start process is further executed (step S148). . In this process, the CPU 31 sets an RB game flag and sets the number of JAC winnings. For example, 8 times. Next, CPU31 is J
Set the number of AC games. For example, 12 times.

If the determination condition is negative in step S146 of FIG. 19, the CPU 31 advances the process to step S149 to determine whether or not the BB winning is in BB. Specifically, the determination condition is affirmed when the BB game flag is set and the RB winning flag is set, and the determination condition is denied otherwise. If the determination condition is affirmed, the CPU
31 pays out medals assigned to the RB award (step S150), and executes an RB start process (step S151). The RB start process in step S151 is performed in step S151.
Since it is the same as that of 148, description is abbreviate | omitted.

On the other hand, if the determination condition in step S149 is negative, the CPU 31 advances the process to step S152 and determines whether or not it is a single FB winning. Specifically, the determination condition is affirmed when the CB game flag is cleared and the FB winning flag is set, and otherwise the determination condition is denied. When the determination condition is affirmed, the CPU 31 determines that F
The medal assigned to the B prize is paid out (step S153), and the FB game start process is executed (step S154). In this process, the CPU 31 sets an FB game flag and sets the number of FB games to “1”.

If it is not a single FB winning, the determination condition in step S152 is denied, and the CPU 31 advances the process to step S155 to determine whether or not the CB winning is in CB (step S155).
. Specifically, when the CB game flag is set and the FB winning flag is set, the determination condition is affirmed, and otherwise, the determination condition is negative. If the determination condition is affirmed, the CPU 31 pays out medals assigned to the FB prize (step S156) and executes the FB game start process (step S157). Since the FB start process in step S157 is the same as that in step S154, description thereof is omitted.

If it is not the FB winning in CB, the determination condition in step S155 is denied, and the CPU 31
Advances the process to step S158 to determine whether or not the BB game is in progress (step S158).
. Specifically, the determination condition is affirmed when the BB game flag is set, and the determination condition is denied otherwise. When the determination condition is affirmed, the CPU 31 executes a BB game end determination process (step S159).

FIG. 20 shows the contents of the BB game end determination process. In this process, the CPU 31 determines whether or not a medal has been paid out (step S180). If there has been a medal payout, the CPU 31 adds the acquired number of games to the acquired number in the BB game (step S181).
If no medal is paid out in the game, the process of step S181 is omitted. When the process of step S181 is completed, the CPU 31 advances the process to step S182 to determine whether the acquired medal number exceeds the reference number. Determine. The number of medals won is
The CPU 31 calculates by adding the number of medals paid out during the period from the start of the BB game to the current game. In this sense, the CPU 31 functions as an acquired quantity calculating means for calculating the acquired medal number (acquired quantity). Here, the reference number X1 is the maximum number MAXbb allowed per BB game, one game in the BB game (next one game)
When the maximum number of sheets that can be acquired in step S is Z1, X1 = MAXbb-Z1.
In the example shown in FIG. 20, the maximum number of allowed MAXbb allowed for the entire BB game is 465, and the maximum number of medals that can be acquired in one game in the BB game is 15. Therefore,
450 sheets is the reference number. By setting the reference number in this way, it is possible to determine whether or not there is a possibility that the maximum acquired number MAXbb will be exceeded in the next game when the game is finished.

If the number of acquired medals exceeds 450 and the determination condition in step S182 is negative, the CPU 31 advances the process to step S183, and displays the number of acquired medals during the BB game (step S183). On the other hand, if the number of acquired medals exceeds 450, the BB game flag is cleared (step S184), and whether or not the RB game is in progress is determined by R.
The determination is made with reference to the B game in-progress flag (step S185). If the RB game is in progress, the RB game in-progress flag is cleared (step S186). Thereby, during the period when the RB game is won and the RB game is executed during the BB game, even if the original end condition of the RB game is not reached, the RB game is interrupted if the acquired medal number exceeds the reference number Is possible. In addition, when an RB prize is won during the BB game, an RB game start process (S151) is performed. If it is determined that the reference number is exceeded in the game won the RB prize, the BB game flag is cleared. (S184) and the RB game flag is cleared (S186)
Therefore, it is possible to control to end the BB game without executing the RB game even once. Note that, during the single RB game that is not in the BB game, the determination condition of S158 is denied, so the RB game is not ended without starting the RB game. Further, the CPU 31 that executes the process of step S182 functions as a comparison unit that compares the number of acquired medals (acquired quantity) with a reference number (reference quantity) smaller than the maximum acquired number of sheets MAXbb (predetermined quantity). Furthermore, CPU3 which performs the process of step S184-step S186
When the number of acquired medals (acquired quantity) exceeds the reference number (reference quantity) with reference to the comparison result of the comparison means, the BB game (specific game) is ended in the current game and the next game is started. It functions as a game state management means for shifting the game state to the normal game.

In the BB game end determination process, the maximum acquired number MAXbb may be fixed, but the slot machine 1 of the present embodiment adjusts the maximum acquired number MAXbb according to the payout rate. In the BB game, the winning probability of the RB award is higher than that in the normal game, so that the number obtained per unit game is large. Therefore, the payout rate is high during the BB game. From the viewpoint of suppressing the player's euphoria, it is preferable to set a certain limit on the payout rate. If an upper limit is set for the payout rate, the upper limit may be exceeded if the BB prize is won in a short period of time. Therefore, by adjusting the value of the maximum acquired number MAXbb according to the payout rate, it is possible to adjust so as not to exceed the upper limit of the payout rate. In this case, it is preferable to calculate the ratio of the total OUT number with respect to the total IN number as a payout rate, and to determine the maximum acquired number MAXbb so as not to exceed the maximum payout rate.

Further, as described above, the reference number is set to a value obtained by subtracting the maximum medal number that can be acquired in the next game from the maximum acquired number MAXbb. For example, it is assumed that the JAC award is 15 in the RB in the BB, the maximum award of the award of the BB game other than the RB game is 12, and the maximum number of winning MAXbb is 465. In this case, in RB in BB, FIG.
As shown in the figure, the reference number of sheets is 450 sheets obtained by subtracting 15 sheets from the maximum obtained number of sheets. in this case,
The number of games acquired immediately before the game is 450 or less, and the number of games acquired in the current game is 450.
It is allowed to be from 465 sheets to 465 sheets. On the other hand, the next game is a BB other than the RB game.
In the case of a game, as shown in FIG. 22, the reference number is obtained by subtracting 12 pieces from the maximum obtained number.
It becomes 3 sheets. Accordingly, the number of acquired games in the immediately preceding game is 453 or less, and the number of acquired games in the current game is allowed to be 453 to 465.

FIG. 23 shows an example in which the reference number of sheets is set to 450 and RB in BB ends in the middle. In this example, the number of games acquired in the RB game in the BB game is 410. R
Game B wins the JAC Award 8 times or ends with 12 games. That is, the end condition is associated with the number of games. Therefore, if the game does not progress by the number of times that the end condition is satisfied, the RB game does not end originally. However, if the RB prize is won in a state where the acquired number is close to the reference number, there is a very high possibility that the maximum acquired number MAXbb will be exceeded in the RB in the BB. Therefore, in the present embodiment, in the RB in the BB, the BB game end condition by the reference number is prioritized over the RB game end condition, and if the acquired number of the game exceeds the reference number, the RB Even during the game, the RB game is forcibly terminated, and the CPU 31 manages the game state so that the next game becomes the normal game. In this example, after shifting to RB in BB, the JAC award is won for 3 consecutive games, and the number of acquisitions is 4
55 sheets, exceeding the standard number. For this reason, in a game where the number of acquisition is 455, RB
Priority is given to the BB game end condition over the game end condition, the RB game is ended,
The next game is transferred to the normal game.

FIG. 24 shows a game progress example in which the reference number is set to 450 and the game returns to the normal game without shifting to the RB game even if the RB prize is won. In this example, the number of acquired games won RB in the BB game is 452. The RB game is started by winning the RB award. However, if the reference number is exceeded at the time of winning the RB award, there is a very high possibility that the maximum acquired number MAXbb will be exceeded in the RB during BB. Therefore, in the present embodiment, for the RB winning in the BB game, the BB game end condition with the reference number is prioritized over the RB game start condition, and the number of acquired games exceeds the reference number Even if the RB prize is won, the CPU 31 manages the game state so that the next game becomes the normal game without starting the RB game. In this example, when the RB prize is won, the acquired number is 452, which exceeds the reference number. For this reason, the BB game end condition is prioritized over the RB game start condition in the game with 452 acquired games, the BB game is ended, and the next game is shifted to the normal game.

Returning to FIG. If it is determined in step S158 that the BB game is not being played, the CPU 31 advances the process to step S160 to determine whether or not a BB prize has been won. When the BB prize is won, a predetermined number of medals are paid out (step S161), and BB
A game start process is executed (step S162). FIG. 25 shows details of the BB game start process. As shown in the figure, the CPU 31 sets a BB game flag (step S1).
87) The acquired number count in the BB game is cleared (step S188). Thereby, the accumulation of the number of acquisitions from the next game is executed.

On the other hand, if it is determined in step S160 that the BB winning is not met, the CPU
In step S163, the process advances to step S163 to determine whether the CB game is in progress. Specifically, CB
The judgment condition is affirmed when the in-game flag is set, and the judgment condition is denied otherwise. When the determination condition is affirmed, the CPU 31 executes a CB game end determination process (step S164).

FIG. 26 shows details of the CB game end processing. As shown in the figure, the CPU 31 determines whether or not a medal has been paid out (step S190). If a medal has been paid out, the acquired number of games in the FB game is added (step S191). ). If no medal is paid out in the game, the process of step S191 is omitted. When the process of step S191 is completed, the CPU 31 advances the process to step S192 to determine whether the acquired medal number exceeds the reference number. Determine. Here, the reference number X2 is CB
X2 = MAXcb−Z2, where MAXcb is the maximum number of games allowed for the entire game, and Z2 is the maximum number of games that can be acquired in one game (the next game) in the CB game. In this example, the maximum number of acquisitions allowed in the entire CB game is 253, and the maximum acquisition number that can be acquired in one game in the CB game is 15. Accordingly, 238 sheets are the predetermined number.

If the number of acquired medals exceeds 238 and the determination condition in step S192 is negative, the CPU 31 advances the process to step S193 and displays the number of acquired medals during the CB game (step S193). On the other hand, when the number of acquired medals exceeds 238, the CB game flag is cleared (step S194), and whether or not the FB game is in progress is determined.
The determination is made with reference to the B game in-progress flag (step S195). If the FB game is in progress, the FB game in-process flag is cleared (step S196). That is, when the acquired number exceeds the reference number, the CB game is ended. As a result, the maximum number of acquisitions MAX allowed for the entire CB game
It is possible to adjust so as not to exceed cb.

In the CB game end determination process, as in the above-described BB game end determination process, the maximum acquired number MAXcb may be fixed. However, the slot machine 1 of the present embodiment determines the maximum acquired number MAXcb according to the payout rate. It is adjusting. In the CB game, the winning probability of the CB award is higher than that in the normal game, so the number obtained per unit game is large. Therefore, the payout rate becomes high during the CB game. From the viewpoint of suppressing the player's euphoria, it is preferable to set a certain limit on the payout rate. If an upper limit is set for the payout rate, the upper limit may be exceeded if the CB prize is won multiple times in a short period of time. Therefore, by adjusting the value of the maximum acquired number MAXcb according to the payout rate, it is possible to adjust so as not to exceed the upper limit of the payout rate. In this case, it is preferable to calculate the ratio of the total OUT number with respect to the total IN number as a payout rate, and to determine the maximum acquired number MAXcb so as not to exceed the maximum payout rate. Further, as described above, the reference number is set to a value obtained by subtracting the maximum medal number that can be acquired in the next game from the maximum acquired number MAXcb.

Returning to FIG. If it is determined in step S163 that the CB game is not being played, the CPU 31 advances the process to step S165 to determine whether or not a CB winning is achieved. When a CB prize is won, a predetermined number of medals are paid out (step S166), and a CB game start process is executed (step S167). FIG. 27 shows details of the CB game start process. First, the CPU 31 sets a CB game flag (step S197), and clears the acquired number count during the CB game (step S198). Thereby, the accumulation of the number of acquisitions from the next game is executed.

Next, the winning determination process (step S31 in FIG. 12) in the RB game will be described. FIG. 28 shows a detailed flowchart of the winning determination process in the RB game. First, CP
U31 determines whether or not it is a JAC prize (step S200). If it is a JAC prize, a predetermined number of medals are paid out (step S201). Completion of medal payout processing or J
If it is not AC winning, it is determined whether or not an RB game is in progress (step S202). If the RB game flag is set, the CPU 31 determines that the RB game is being played, advances the process to step S203, and executes an RB game end determination process.

FIG. 29 is a flowchart showing details of the RB game end determination process. As shown in the figure, the CPU 31 first determines whether or not it is a JAC prize (step S210). If it is a JAC prize, the JAC prize number is subtracted by "1" (step S211), and the number of JAC prizes is further increased. Is determined to be “0” (step S212). JAC winning number is “0”
If so, the CPU 31 clears the RB game flag (step S217). On the other hand, if the JAC winning number is not “0”, the CPU 31 displays the remaining number of JAC winning numbers (
In step S213, the number of JAC games is decremented by “1” (step S214). If the JAC prize is not won, the CPU 31 proceeds from step S211 to step S2.
The processing up to 213 is omitted, and the processing proceeds from step S210 to step S214.
Thereafter, the CPU 31 determines whether or not the remaining number of JAC games is “0” (step S21).
4) If “0”, the RB game flag is cleared (step S217).
If not, the remaining number of JAC games is displayed (step S216).

The description returns to FIG. The above-described RB game end determination process ends, or RB
If the in-game flag is cleared and the determination condition in step S202 is negative, C
The PU 31 determines whether or not the BB game is in progress with reference to the BB game in-progress flag (step S).
204). When the BB game flag is set, the CPU 31 determines that the BB game is being played, advances the process to step S205, and executes a BB game end determination process. On the other hand, if the BB game flag is cleared, the CPU 31 determines that the BB game is not in progress and ends the RB game winning determination process. The BB game end determination process is shown in FIG.
Since it has already been described using 0, the description is omitted.

Here, even if the JAC prize is won during the RB game in the BB game, if it is determined that the reference number is exceeded in the BB game end determination process (S205), the BB game flag is cleared (S184). ) And the RB game in-progress flag is cleared (S186), it is possible to control to end the BB game even when the original end condition of the RB game has not been reached. Note that, during the single RB game that is not in the BB game, the determination condition of S204 is denied, so the RB game is not interrupted in the middle of the RB game.

Next, the winning determination process in the FB game (step S32 in FIG. 12) will be described. FIG. 30 shows a detailed flowchart of the winning determination process in the FB game. First, CP
U31 determines whether or not the FB prize is won (step S220), and if it is the FB prize, a predetermined number of medals are paid out (step S221).

If the FB prize has not been won, the CPU 31 determines whether or not the FB small role prize has been won (step S222). The FB small role award is a small role award adopted in the FB game, and includes an FB bell role, an FB watermelon role, an FB cherry role, and the like. When winning the small bonus for FB, the CPU 31 pays out the number of medals corresponding to the winning prize (step S223). If the medal payout process ends, or if the determination condition in step S222 is negative without winning the FB small role award, the CPU 31 refers to the FB game flag to determine whether the FB game is in progress. Judgment is made (step S224).
B game end determination processing is executed (step S225). FIG. 31 shows a flowchart of the FB game end determination process. As shown in this figure, in the FB game end determination process, the FB game number is subtracted by “1” (step S230), and it is determined whether or not the remaining FB game number is “0” (step S231). If the number of FB games is “0”, the CPU 31
Clears the FB game flag (step S232). As described above, since the number of FB games is set to one, the FB game does not continue in principle. However, F
When the FB prize lottery is executed during the B game, the FB prize can be won again in the FB game. Therefore, the FB game continues apparently. The unit of the FB game is the same as that of one game, and only the FB prize is won continuously.

If the FB game end determination process ends, or if the FB game is not in progress,
U31 advances the process to step S226, determines whether or not the FB prize is won, and executes the FB game start process if it is the FB prize (step S227). Next, whether or not a CB game is in progress
The determination is made with reference to the B game in-progress flag (step S228). If the determination condition is affirmed, a CB game end determination process is executed (step S229). Since the CB game end determination process has already been described with reference to FIG. 26, the description thereof is omitted here.

Next, the one-game end process (step S34 in FIG. 12) will be described. 32 and 33 are flowcharts showing the processing contents of one game end processing. The CPU 31 sequentially determines whether or not the replay winning flag, the watermelon winning flag, the bell winning flag, and the cherry winning flag are set (steps S240 to S243), and clears the set winning flags (steps S245 to S248). ). Next, the CPU 31 determines whether or not the BB winning flag is set (step S249). If the BB winning flag is set, the CPU 31 further determines whether or not a BB prize has been won (step S25).
0) If the prize is won, the BB winning flag is cleared (step S251). On the other hand, if no prize has been won, it is carried over to the next game without clearing the BB winning flag.

Next, the CPU 31 determines whether or not the CB winning flag is set (step S).
252). If the CB winning flag is set, the CPU 31 further determines whether or not a CB prize has been won (step S253), and if it has won, the CB winning flag is cleared (step S254). On the other hand, if it is not won, it is carried over to the next game without clearing the CB winning flag.

Next, the CPU 31 advances the processing to step S255 shown in FIG. 33, and determines whether or not the single RB winning flag is set (step S255). If the single RB winning flag is set, the CPU 31 further determines whether or not the RB prize has been won (step S256). If the single RB winning flag has been won, the single RB winning flag is cleared (step S257).
. On the other hand, if no winning is made, it is carried over to the next game without clearing the single RB winning flag.

Thereafter, the CPU 31 sequentially determines whether the RB winning flag during BB, the FB winning flag during CB, and the JAC winning flag are set (steps S258 to 260), and clears the set winning flag (step S261). ~ S263).

[Second Embodiment]
A slot machine 1c according to a second embodiment of the present invention will be described. Slot machine 1
c has the same configuration as the slot machine 1 described above. Therefore, in the following description, the names and symbols of the respective parts used in the description of the slot machine 1 are used as they are. The slot machine 1c is different from the slot machine 1 in the following two points.
(Α) A point where a BB1 award and a BB2 award are provided instead of the BB award (β) When the RB award is won during the BB game, the RB game is not executed only once,
Points in which a plurality of RB games are continuously executed until the BB game is ended. In the following description, the difference between the slot machine 1c and the slot machine 1 will be described in relation to these points.

<About α>
Each of the BB1 award and the BB2 award is a BB game start prize similar to the BB award. The BB1 award and the BB2 award have different winning combinations. Further, the maximum number (predetermined quantity) acquired during the BB game is set differently for each start prize of the BB game. For example, BB
While the maximum number obtained in the BB game that starts after winning the first prize is set to 465,
The maximum number obtained in the BB game that is started after winning the B2 prize is set to 300. Also,
The winning probability of the RB prize in the BB game is set differently for each start prize of the BB game. For example, the value of the lottery classification data for the BB1 prize is set to 50, while the value of the lottery classification data for the BB2 prize is set to 150. In other words, R in the BB game where the maximum number of acquisitions is large
The winning probability of the B prize is set low, and the winning probability of the RB prize in the BB game with a small maximum number of winnings is set high, so that a balance is established between both BB games. It should be noted that the maximum number obtained in both BB games may be made different without balancing, or three or more BB game start prizes may be provided.

The CPU 31 of the slot machine 1c sets a prize group lottery table according to the game mode. The processing for performing this setting is processing corresponding to step S14 in FIG.
FIG. 37 is a diagram showing an example of processing for setting a prize group lottery table corresponding to a game mode. In the figure, a circle means that the corresponding prize is a lottery object during the game of the corresponding game mode, and a cross means that the corresponding prize is not a lottery object during the game of the corresponding game mode. The triangle mark means that it is not necessary to become a lottery target during the game in the game mode corresponding to the corresponding prize. The CPU 31 performs the above-described process so that the BB1 prize and the BB2 prize are subject to lottery in each of the normal game and the FB game. The game mode is specified with reference to the in-game flag.

FIG. 38 is a diagram showing the relationship between the game mode and the in-game flag. The relationship shown in the figure is common to the slot machine 1. In other words, the BB game flag is set only during the BB game, the RB game flag is set only during the RB game or during the BB game, and the CB game flag is only set during the CB game. The FB game flag is set only when the FB game or the CB FB game is in progress. These in-game flags are cleared in other cases. Therefore, for example, if during the BB game, the BB game flag and the RB game flag are set, and the CB game flag and the FB game flag are reset. By referring to, it is possible to specify that the game mode is the RB game in BB.

As described above, as a matter of course, in the slot machine according to the present embodiment, in the internal lottery data indicating the winning prize or the lose that is the winning prize, the BB 1 winning flag and the BB winning flag are not secured. The BB2 winning flag is secured. In addition, a stop table and a winning symbol combination table for the BB1 award, a stop table and a winning symbol combination table for the BB2 award are provided instead of the stop table and the winning symbol combination table for the BB award. .

<About β>
FIG. 39 is a flowchart showing the contents of the RB game end determination process. As shown in the figure, the CPU 31 of the slot machine 1c first determines whether or not it is a JAC prize (step S210). If it is a JAC prize, the JAC prize number is subtracted by “1” (step S2).
11) Further, it is determined whether or not the number of JAC winnings has become “0” (step S212).
.

If the JAC winning number is “0”, the CPU 31 clears the RB game flag (step S217), determines whether or not the BB game is in progress (step S218), and if the BB game is in progress, the RB game. The middle flag is set (step S219), the number of JAC prizes (for example, 8 times) is set (step S220), and the RB game end determination process is ended. That is, when one RB game ends during the BB game, the CPU 31 starts the next RB game so as to be continuous with the RB game. On the other hand, if it is not during the BB game, the CPU 31
Omits the processing from step S219 to step S220, and ends the RB game end determination processing.

On the other hand, if the JAC winning number is not “0”, the CPU 31 displays the remaining number of JAC winning numbers (step S213), and subtracts the JAC game number by “1” (step S214).
). If the JAC prize is not won, the CPU 31 skips the processing from step S211 to step S213, and proceeds from step S210 to step S214. Thereafter, the CPU 31 determines whether or not the remaining number of JAC games is “0” (step S215). If the remaining number of JAC games is “0”, the process proceeds to step S217. On the other hand, if the remaining number of JAC games is not “0”, the CPU 31 displays the remaining number of JAC games (step S216), and ends the RB game end determination process.

[Third Embodiment]
A slot machine 1b according to a third embodiment of the present invention will be described. Slot machine 1
b has the same configuration as the slot machine 1c described above. Therefore, in the following description, the names and symbols of the respective parts used in the description of the slot machine 1c are used as they are. Slot machine 1
b differs from the slot machine 1c in the following two points.
(Γ) In a BB game, a plurality of RB games (special game periods) are continuously executed from the start to the end thereof. (Δ) In a CB game, a plurality of FB games (special game periods) are continuously provided from the start to the end. Points to be executed in the following description, the points where the slot machine 1b is different from the slot machine 1c in relation to these points will be described.

FIG. 40 shows the relationship between the game mode and the in-game flag. As shown in the figure, in the present embodiment, the BB game and the BB in-game are equivalent because there is no normal game in the BB game, and the CB game is in the absence of the normal game in the CB game. And C
The middle B FB game is equivalent. That is, the value of each in-game flag corresponding to the BB game is uniquely determined, and the value of each in-game flag corresponding to the CB game is also uniquely determined. Therefore, the CPU 31 can specify the game mode with reference to the in-game flags having the relationship shown in the figure.

FIG. 41 is a flowchart showing the processing content of the BB game start processing. The process content shown in this figure is different from that shown in FIG. 25 only in that a process subsequent to step S188 exists. As shown in FIG. 41, the CPU 31 sets a flag during the BB game (step S187), and clears the acquisition number count during the BB game (step S188). Thereby, the accumulation of the number of acquisitions from the next game is executed. Next, the CPU 31 sets an RB game in-progress flag (step S1881), and sets the number of JAC winnings (step S18).
2). For example, 8 times. As described above, the CPU 31 performs B in the BB game start process.
Processing for starting the B game and the RB game is performed. The difference in processing contents is the same for the CB game start processing. That is, in the CB game start process, the CPU 31 performs a process for starting the CB game and the FB game.

<Modification>
Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the invention is limited to the embodiments disclosed herein. However, the present invention can be changed as appropriate without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, and a gaming machine and a control method therefor are also included in the technical scope of the present invention. Must be understood as being. For example, the following modifications are naturally included in the present invention.

(1) In the slot machine 1 of the above-described embodiment, a ring buffer is provided as the storage area 343 of the RAM 34, and 4-bit IN data and 4-bit OUT data are stored in one stage buffer. Store only OUT data in one stage buffer
Data storage may be omitted. For example, in a slot machine that allows only three bets at the start of one game, the number of inserted 400 games is 1200, and it is not necessary to store the number of inserted games for each game. The number of sheets may be fixed to 1200 sheets. In addition, storage of IN data may be omitted even in a slot machine that allows only three bets in the base game and the BB game and only one bet in the RB game. In this case also, the total IN number is fixed to 1200 in calculating the payout rate. IN data and O
There is an error compared to the case where both of the UT data are stored and the output rate is calculated, but since 4 bits of OUT data for two games can be stored in one buffer, the ring buffer is stored in the RAM 34. The storage area 343 can be halved and the storage area can be saved.

Also, a storage area 341 for storing the total IN number, a storage area 342 for storing the count value of the game counter, the number of inserted medals IN and the number of paid out medals O in each of the past 400 games.
The storage area 343 for storing the UT and the storage area 344 for storing the total number of OUTs are supplied with power.
It is preferable that the RAM 34 is backed up by a battery or the like so that the stored value can be saved even in the OFF state. It is preferable that a predetermined value is set as an initial value in advance so that the buffer value does not become unstable when the power is turned on for the first time.

(2) The embodiment described above relates to the slot machine, but the present invention can also be understood as a game program or a game machine imitating the slot machine described above. In this case, instead of the reels R1 to R3, the images of the reels R1 to R3 may be displayed on the display, and their operations may be controlled according to the game program. further,
Of course, the present invention can be applied to a video slot for displaying an image of a reel on a display such as a liquid crystal display device instead of the mechanical reels R1 to R3.

(3) Although the slot machine of the above-described embodiment or modification employs medals as game media, it may adopt pachinko balls and medals. In this case, the conversion number of medals and pachinko balls may be determined in advance, and the number of pachinko balls may be converted into the number of medals according to the conversion number and stored electronically as credits. For example, five pachinko balls may be assigned per medal.

(4) Although the slot machine of the above-described embodiment or modification can execute both the BB game and the CB game, it may be a slot machine that can execute either one of them. Moreover, although the maximum acquired number of sheets MAXbb and MAXcb are adjusted according to the payout rate, it is needless to say that it may be fixed.

(5) In the slot machine of the above-described embodiment or modification, a replay time game (hereinafter referred to as an RT game) may be adopted. A replay time game is a game set with a higher probability of winning a replay prize than a normal game. For example,
The internal lottery may be executed using the prize group lottery table TBL12 shown in FIG. In this case, the RT game is defined as a predetermined period or the entire period from the start of the BB game to the end of the BB game.

In a slot machine in which the BB game ends when the specified number of acquired games is reached, it is preferable that the player can play the game so as to reach the specified acquired number of games by reducing the number of inserted games as much as possible. In other words, it is preferable that the game can be performed so that the net increased number obtained by subtracting the inserted number from the acquired number is increased. When the RT game is started during the BB game, the amount lost in the internal lottery in the base game is won by replay, and stop control of each reel is executed so that the replay prize is won in that game. A game that has won the replay award will not be counted as an acquired number because both the IN number and the OUT number will be zero. In other words, it is unrelated to the number obtained. Therefore, a useless IN number is not generated, and a game advantageous to the player can be performed. When the RT game is started simultaneously with the start of the BB game, the RT game may be ended when a predetermined number of BB games are consumed, or the RT game may be ended when a specific symbol is prepared. Good.

Or you may employ | adopt stop control which can win a replay prize when the pushing order of stop operation corresponds for the stop control of each reel of the replay prize of RT game. In this case, since it is possible to control whether or not a replay winning is possible without notifying the pressing order of the stop operation, there are a BB game that notifies the pressing order of the stopping operation related to the replay winning and a BB game that does not notify. Alternatively, a plurality of BB games having different BB game modes can be provided such that the frequency of the push order notification of the stop operation for the replay winning and the game period are varied.

By the way, when one game is defined from a bet operation in which a player inserts a medal to a bet operation of the next game in order to start a certain game, one game progresses by sequentially executing a plurality of processes. The CPU 31 controls such that the time from a predetermined process to a predetermined process of the next one game exceeds a predetermined time among a plurality of processes of one game. This
It is possible to prevent a large amount of medals from being consumed in a short time. However, since the replay game does not require insertion of medals, for the replay game in the BB game, the CPU 31 may invalidate the above-described time management to shorten the time of one game. As a result, during the BB game, the RT game is started and the time of one game can be shortened, so that it is possible to perform a BB game that can acquire the specified number of acquisitions in a short time without increasing the number of useless throws. For the player, an efficient game can be played. 3 during the regular game
In a slot machine in which a bet is fixed, a BB game in which the number of net increase is increased can be achieved by enabling one bet during the BB game. In addition, the above is C
The same can be said for the B game.

(6) In the above-described embodiment and modification, the RB game has been described as executing a JAC game. However, the present invention is not limited to this, and a unit game compared to a normal game. As long as the expected value of the number of medals that can be obtained by the player is large, any value may be used. For example, the winning probability of the internal lottery of the small role prize may be higher than that of the normal game.

(7) In the embodiment and the modification described above, the IN number for the replay winning is counted as it is, and the number of the next replay game input is set to “0” (step S50 shown in FIG. 14). The number of inserted game winning games is set to 0, and the number of replay games that can be executed under the same conditions as the previous game is set to the number of previous game input, for example 3
It may be called a sheet. In this case, the IN number and OUT of the game that won the replay
Both numbers are zero. Specifically, the CPU 31 may execute the medal IN number counting process shown in FIG. First, the CPU 31 determines whether or not a replay prize has been won (step S300). If the replay prize is won, the number of insertions is stored in a predetermined storage area of the RAM 34 (step S301), and the number of insertions of the game is set to “0” (step S3).
02). On the other hand, if the replay prize is not won, steps S301 and S302 are omitted. Next, the CPU 31 determines whether or not the game is a replay game (step S303). If the game is a replay game, the CPU 31 reads out the number of games that have won the replay award from a predetermined storage area of the RAM 34, Set to the number of inserted games (step S3)
04). On the other hand, if the game is not a replay game, the process of step S304 is omitted. Thereafter, the CPU 31 calculates the total IN number (step S305). Note that the processing in step S305 is the same as the processing in steps S52 to S56 described with reference to FIG. 14 in the above-described embodiment.

(8) In the above-described embodiment and modification, the RB game is played by the JA by the JAC award.
As an example of the game that is ended when the C game is played 12 times or when a maximum of 8 times is won, FIG.
As indicated by the triangular mark 7, a small role game in which a watermelon prize, a bell prize, and a cherry prize are added to the JAC prize during the RB game may be used. Alternatively, there may be no small JAC award, only a watermelon award, a bell award, and a cherry award, and a small role high probability game in which a lottery probability of those awards is increased as compared with a normal game. In any case, the RB game is a game in which the sum of the lottery probabilities (composite probabilities) of the small role prize that does not change the type of the game even when winning is increased.
