Abstract

PROBLEM TO BE SOLVED: To balance profit between a player and a shop and to enjoy playing by facilitating the generation of a special play state when specified conditions are satisfied and suppressing the rate of facilitating continuation when the specified conditions are satisfied again during this state. SOLUTION: When a special play state is generated, special play is performed by opening an opening/closing door 5a of a special variation prize winning device 5 for prescribed time. Such a cycle is continuously performed to the prescribed cycle of respective cycles on the condition that a game ball passes through a continuation prize winning area inside the opening/closing door 5a. When the specified conditions are satisfied during this special play, the game is changed to the state of facilitating the generation of special play. When the state of satisfying the specified conditions is generated again during this facilitating state, the state of facilitating the generation of special play state is continuously generated and the rate of that continuation is suppressed by changing the rate of specified condition establishment. Thus, the player can easily continue the special play and the profit can be balanced between the player and the shop.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a continuation of a state in which a special game state (for example, a big hit) can be generated a predetermined number of times by changing a satisfaction rate of a specific condition (for example, a probability variation symbol). The present invention relates to a gaming machine such as a pachinko machine capable of suppressing gambling.

[0002]

2. Description of the Related Art Conventionally, a variable display device (for example, an image display device) capable of variably displaying a plurality of pieces of identification information (hereinafter referred to as a special symbol or a special figure as appropriate) is variably displayed, and the stop display result is obtained. For example, there is known a gaming machine capable of generating a big hit state advantageous to a player when the hit pattern is a big hit symbol (special stop mode) such as "2", "2", and "2". Also, recently, when a specific condition is satisfied when a big hit occurs, the big hit occurrence probability is changed to a high probability state to make the next big hit occurrence easy (probability variation state) for a predetermined period. There is also a general gaming machine in which a large number of big hits can be generated within the game machine so as to enhance the interest and willingness of the player to play.

In a gaming machine that performs the above-described probability variation, for example, a predetermined number (for example, 5
) Is a specific symbol (probability-variable symbol), and if the specific symbol (for example, “7”, “7”, “7”) is completed, after the big hit is completed, the next big hit is, for example, 2 The probability of a big hit until it occurs twice, for example, from 1/300 to 10
At / 300 or the like, a probability variation state in which the normal probability (low probability state) is changed to the high probability state is generated. In addition, if a big hit occurs again with a specific symbol among the two big hits that occur during the high probability state, after the big hit ends,
The probability fluctuates until a big hit occurs twice. Alternatively, in the above-mentioned gaming machine, out of all the big hit symbols (30 pieces),
A predetermined number (for example, 15) is set to a specific symbol (probability variation symbol). If the specific symbol is completed, after the end of the jackpot, the occurrence probability of the jackpot is changed to a high probability state until the next jackpot occurs. Then, when a big hit occurs again in a specific symbol at the next big hit, the probability fluctuation state is continued and generated until the next big hit occurs again.

[0004] Further, instead of increasing the probability of occurrence of a big hit symbol, an auxiliary variable prize winning device (for example, a normal variable prize winning device: a so-called puden) is provided at a special figure starting port, and the auxiliary variable prize winning device is provided. An auxiliary variable display device (e.g., a normal symbol display device) for determining an open condition is provided. To increase the winning rate to the special figure starting port by frequently opening the auxiliary variable prize-winning device (Puden) by increasing the probability of hitting the game, and shortening the variable game time of the figure. By doing
There is also a case where a probability variation state of a general map which facilitates the next big hit is generated.

[0005]

By the way, the conventional gaming machines have the following problems from the viewpoint of the number of jackpot occurrences and the profit balance and gambling of gaming arcades. (B) In a conventional gaming machine, for example, in the case of a big hit with a probable variable symbol, the big hit probability is increased until the next big hit occurs a predetermined number of times (for example, two times) after the big hit is completed, and a big hit is easily generated. If the big hit again with the probability change symbol during the probability change, since the control that the probability change continues until the big hit occurs twice again from that time was performed, in some cases, the big hit with the probability change symbol is continuous And the probability fluctuation state lasts for a very long time, and the jackpot may occur many times (for example, several tens of times) continuously. As a result, it has been very difficult to balance the profits between the player and the game store.

(B) From the viewpoint of the above (a), as a game store, the winning rate of game balls to the special figure starting winning opening is extremely lowered by, for example, nail adjustment, or the probability setting value of the big hit is lowered. Also, the gaming machine manufacturer also manufactures machines with reduced initial value of the probability value, etc., and it is not easy to hit a big hit (danger of inducing a large loss to the player) Once), once a big hit occurs in the probability variation symbol, there is a risk that gaming performance with high gambling (high gambling property) may be obtained such that a large number of gaming balls can be obtained. (C) On the other hand, if the gambling property is extremely reduced, a great loss will not be induced to the player, but the pachinko game lacks the fun for the player. Therefore,
There has been a demand for a gaming machine having gaming performance that can be enjoyed by many players while suppressing gambling.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gaming machine in which the profits of a player and a game store can be balanced and the gaming performance can be enjoyed by many players while suppressing gambling.

[0008]

To achieve the above object, a gaming machine according to the first aspect of the present invention includes a variable display device capable of variably displaying a plurality of pieces of identification information. Based on the result of the special stop mode, in a gaming machine capable of generating a special gaming state, if the occurrence of the special gaming state is an occurrence satisfying a specific condition, the generation of the special gaming state is performed. A special game state generation facilitating means for converting to an easy state, and a special game state satisfying a specific condition again during the state where the special game state is easily generated by the special game state generation facilitating means. In this case, the special game state generation facilitation continuation means for continuously generating the state where the special game state is easy to generate, and the continuation rate of the state where the special game state is easily generated,
And a continuation suppressing means for suppressing by changing the satisfaction rate of the specific condition.

In a preferred embodiment, for example, the specific condition is satisfied when the special stop mode occurs in association with a predetermined number of specific symbols.
The continuation suppression means may suppress occurrence of a special stop mode related to the specific symbol. For example, as described in claim 3, the continuation suppressing means may convert the occurrence of the special stop mode related to the specific symbol once generated to an invalid state. For example, as described in claim 4,
The specific condition may be established based on a result of an auxiliary variable display game performed in association with the occurrence of the special game state.

In this embodiment, an example in which the present invention is applied to a type belonging to the so-called "first type" will be described.

B. Configuration of Control System Next, the configuration of the control system in the gaming machine will be described.
FIG. 2 is a block diagram showing an overall configuration of a control system in the gaming machine. In FIG. 2, this control system is roughly composed of an accessory control circuit 100 and a display control circuit 200. The accessory control circuit 100 is a circuit including a microcomputer, and is realized by, for example, a board unit attached to the back surface of the game board 1. The display control circuit 200 is realized by, for example, a circuit board mounted on the back side of the special symbol display device 4 provided on the game board 1.

The accessory control circuit 100 includes an accessory IC 111 composed of a one-chip microcomputer for performing an accessory control necessary for a pachinko game, a ROM 112 storing a control program for the accessory control, a crystal IC, and the like. Frequency divider circuit 11 for dividing the oscillation frequency to obtain the basic clock of accessory IC 111
3, a power supply circuit 114 for supplying necessary power to the accessory IC 111 and the like, a low-pass filter 115 for receiving various information signals, and a buffer for outputting a signal from the low-pass filter 115 to the accessory IC 111 via the bus 116. The signal from the gate 117 and the accessory IC 111 is transferred to the bus 1
Output port 118 which receives via output port 16 and output port 1
A driver 119 that drives a control signal input through the control unit 18 to generate various drive signals and outputs the generated drive signals to each device;
A sound generator 120 that generates a sound effect required for a game (or may perform voice synthesis), and amplifies an audio signal from the sound generator 120 and outputs the amplified signal to a speaker 121a provided at a predetermined location of the gaming machine. It is configured by an amplifier 121 and an interface circuit 122 that outputs a signal related to game information to the hall management device 201 based on a control signal output from the accessory IC 111. The accessory IC 111 incorporates a CPU 131 for performing arithmetic processing and a RAM 132 for temporarily storing data necessary for setting and controlling a work area.

The low-pass filter 115 includes the above-described special figure start switch 6d, ordinary figure start switch 7a, count switch 5d, continuation switch 5c, and probability setting device 1
The signal from 40 is input. Probability setting device 140
Is used to change the setting of the probability of a big hit (usually in three stages), and the gaming machine itself (for example, the accessory control circuit 100)
May be configured by a switch or the like (not shown) provided in the hall, or may be configured to be input from the hall management device 201. From the driver 119, a solenoid for driving the opening and closing operation of the special winning opening 5b (opening / closing door 5a) of the special variable winning device 5, the special figure start memory display 4c, the general figure start memory display 6c, and the normal symbol display The control signal is output to the device 6b, the solenoid that drives the normal fluctuation winning device 6, and various decorative lamps (for example, the side lamp 8c).

The display control circuit 200 includes an accessory IC 111.
In this case, the special symbol display device 4 receives the 8-bit display control signals (reset signal (1 bit), strobe signal (1 bit), command signal (6 bits), etc.) and performs display control. CPU and RO for display control
M, RAM, VDP for image, font ROM, etc. The special symbol display device 4 variably displays a plurality of pieces of identification information (special figures) in a plurality of columns based on a display control signal from the display control circuit 200. Note that the display control circuit 200 supplies a power supply for a backlight and a power supply for a liquid crystal display to the special symbol display device 4, and a ground line is connected thereto.

The management device 201 manages gaming machines, island facilities, and the like in the entire hall. Various signals (for example, a jackpot signal) are input from the accessory control circuit 100, and sales are performed based on the input various signals. The above necessary data is subjected to arithmetic processing, and the processed data is displayed on a display or printed as necessary. In addition, the management device 201 monitors, for example, the acquired pitches of the gaming machine, outputs a stop signal or the like to the gaming machine, and broadcasts in the store.

Here, the accessory IC 111 and the ROM 11
2. The frequency dividing circuit 113 and the display control circuit 200 constitute a special game state generation facilitating means, a special game state generation facilitating continuation means and a continuation suppressing means as a whole. The special game state generation facilitating means is a generation in which the generation of the special game state (big hit) satisfies a specific condition (probability fluctuation symbol, for example, a big hit based on “7”, “7”, “7”). In this case, the occurrence of the special game state is converted to an easy state (changed so that the big hit probability becomes higher than usual).
The special game state generation facilitation continuation means is configured to generate a special game state satisfying a specific condition again while the special game state is easily generated by the special game state generation facilitation means (probability changing game). In the case of a big hit (again, if a big hit occurs due to the probability fluctuation symbol), the easy game condition is easily generated (three big hits are set as one set, and two big hits are generated after the first big hit) ).
The continuation suppressing means determines the continuation rate of a state in which a special game state is easily generated (probability-variable gaming state) by a satisfaction rate of a specific condition (probability of a probability-variation symbol, for example, “7”, “7”, “7”). rate)
Is suppressed by changing.

Note that the specific condition mentioned above is that the probability variation symbols are aligned in a zigzag pattern, which means that the special stop mode is a predetermined number of specific symbols (for example, “7”, “7”,
This is equivalent to the case where the error occurs in connection with “7”). In addition, the specific condition may be established based on a result of an auxiliary variable display game performed in association with the occurrence of the special game state (see an embodiment described later). And the continuation suppression means performs control to suppress the occurrence of the special stop mode related to the specific symbol (that is, performs control to suppress the occurrence of the probability variation symbol). In this case, the control for suppressing the occurrence of the special stop mode performed by the continuation suppression means includes, for example, a control for converting the occurrence of the special stop mode related to the specific symbol once generated to an invalid state (see an embodiment described later). .

C. Outline of Game Next, before explaining the control flow of the accessory control circuit 100, an outline of a game performed by the gaming machine of the present embodiment will be described. When a game ball hit into the game area via the guide rail 2 wins the ordinary variable prize device 6 also serving as a special symbol start-up port, a large number of games are displayed in a plurality of areas of the display section 4a of the special symbol display device 4. Identification patterns (numbers, letters, symbols,
A display (a so-called fluctuating display) of moving (scrolling) of a pattern or the like is performed, and a fluctuating display game (image fluctuating game) is performed. Then, the stop display mode as a result of the variable display game is a predetermined mode (for example,
In the case of "7, 7, 7" or the like, a special game state called a big hit occurs.

When this special game state (big hit) occurs, a special game in which the opening and closing door 5a of the special variable prize winning device 5 is opened, for example, for about 30 seconds (or, for example, a period of up to 10 prizes). . The cycle of the special game is continuously performed, for example, up to a maximum of 16 cycles, on the condition that the game ball passes through the continuous winning area in the special winning opening 5a during each cycle. Here, in the present embodiment, when the occurrence of the special game state is an occurrence that satisfies a specific condition (for example, an occurrence of a big hit based on a probability variation symbol (“7”, “7”, “7”)). In the meantime, the occurrence of the special game state is converted into an easy state (for example, a state in which the jackpot probability fluctuates). If a special game state that satisfies is satisfied (for example, if a big hit occurs again due to the probability variation symbol), the state in which the special game state easily occurs is continuously generated (for example, three big hits are performed). As one set, a jackpot can be generated two more times after the first jackpot, and the continuation rate of a state in which a special game state is easily generated (probability-variable game state) can be determined as a rate of establishment of specific conditions (probability-variable symbol). For example, "7", "7"
The control is performed by changing the rate of establishment of “7”.

It is to be noted that the jackpot probability is increased so that
The game that makes it easy to hit (probability changing game) is a big hit with a specific symbol (when a specific condition is satisfied),
This is a special game in which the probability of a big hit after a predetermined period is set to a higher probability than usual, and is a control performed in the control process of the accessory control circuit 100. In addition, during the above-mentioned special display variable display game or special game, the normal variable prize winning device 6
When a special game ball is further won, the special figure start storage indicator 4c is turned on to store, for example, up to four special figure, and after the special figure change display game or special game is completed, the special figure change based on the storage is performed. The display game is repeated.

On the other hand, when a game ball wins (passes) the ordinary symbol starting port 7 during the game, the ordinary symbol is displayed by changing the identification information (in this case, a single digit number) of the ordinary symbol display device 6b. A variable display game is performed. Then, if the stop display mode as a result of the variable display game is a predetermined mode (for example, “7”), a game value called per-figure is generated. When this game value (per ordinary figure) is generated, a specific game is performed in which the pair of opening / closing members 6a of the ordinary variable prize device 6 is held in an open state in an inverted C-shape, for example, for about 0.5 seconds. This makes it easier for the game ball to win the normal fluctuation winning device 6, thereby increasing the number of executions of the special figure fluctuation display game and increasing the possibility of a big hit. Further, when a game ball is further awarded in the ordinary symbol starting port 7 during the above-mentioned general-figure variation display game, the general-figure start storage display 6c
Are lit and stored, for example, up to four. After the end of the variation display game of the general figure, the variation display game of the general figure is repeated based on the storage.

In addition to a game (probability changing game) in which the big hit probability is increased and the big hit is more likely to be hit twice later, a predetermined special game is further performed in addition to the normal variation display game. Other special games include so-called general-time time reduction control or general-time immediate stop control (for example, shortening the fluctuation time of the general-floor fluctuation display game only until the special-floor fluctuation display game is performed 50 times) (or There is a game state by both). Here, the general time reduction control is a control for shortening the fluctuation time of the fluctuation display game of the general figure from, for example, about 60 seconds to about 6 seconds. When performing a normal variation display game based on the start memory, a predetermined time (for example, 6
The control is such that the fluctuation time is shortened (for example, 2 seconds) and the normal drawing is immediately stopped after the lapse of seconds.

In addition, during the special game, a process of increasing the opening time of the ordinary variable prize winning device 6 at the time of ordinary drawing, for example, to about 3 seconds, and the number of times of opening the normal variable prize winning device 6 at the time of ordinary drawing May be increased from the usual one to three times. It should be noted that by performing such a special game, the number of times of playing a regular figure per unit time increases, and the number of times the regular figure hits increases (since the probability of winning the regular figure is about 1/4). As a result, the number of fluctuations of the special figure increases, resulting in an advantageous state. In addition, during this special game state, the control for immediately stopping the fluctuation of the special figure is usually performed.
It is even more advantageous.

D. Operation of Control System Next, control of the gaming machine performed by the above-described control system will be described with reference to flowcharts shown in FIGS. (A) Main Routine of Accessory Control Circuit FIG. 3 is a flowchart showing a main control process (main routine) performed by the accessory control circuit 100 (the accessory IC 111). This control process is performed based on a reference time (for example, 2 m) generated by the frequency dividing circuit 113 in FIG.
One sequence is performed for each s). That is, in the reset waiting process after the end of the final step, the accessory IC
Each time a reset signal is input to the frequency divider 111 from the frequency dividing circuit 113, the process is executed from step S10.

When the process is started, it is first determined in step S10 whether or not the power is to be turned on. If the power is to be turned on, the power is turned on in step S12, and the current routine ends. In the power-on process, the ROM 11
2, normalization processing of the work area in the RAM 132, setting of I / O registers, processing of setting registers in the system, initialization of flags, and the like are performed. If the power is not turned on in step S10, the process branches to step S14 to execute SW input processing (for example, input processing of the special figure start switch 6d or the general figure start switch 7a).
And proceeds to step S16. In step S16,
Control processing by the accessory IC 111 (steps S18 to S18)
32) The processing NO. Determined in each processing step. According to the (process number), a branch process for performing any one of the processes in steps S18 to S32 is performed. The outline of steps S18 to S32 is as follows.

Step S18: Regular Processing In regular processing, if there is a start memory, the number of start memories is reduced by one, and then a big hit judgment is performed by random number extraction to determine a stop symbol of a special figure. Next, when the stop symbol is the reach symbol, after setting the reach flag, the process number is changed to the number of the variation start process, so that the variation start process is performed in the next sequence. If there is no start memory, the process number is kept as it is for performing the ordinary process, and the ordinary process is repeated in the next sequence.

Step S20: Variation Start Processing In the variation start processing, processing for starting scrolling of a special figure is performed, and the processing number is changed to the number of the symbol stop processing. Step S22: Symbol Stop Process In the symbol stop process, the symbol change is stopped after a predetermined time has elapsed after the scrolling of the special figure has started, and the process number is changed to the number of the stopped symbol determination process. At this time, if the reach flag is set (set in the subroutine of the ordinary processing as described later), the reach scroll of the special figure is performed, and then the last symbol stops.

Step S24: Stop symbol determination process (details will be described later in a subroutine) In the stop symbol determination process, first, after the reach flag is reset, it is determined whether or not the stop symbol is a big hit symbol. The processing number is changed to the number of the fanfare processing if the jackpot is a big hit. Step S26: Detachment process In the departure process, a process of performing display in which all of the left symbol, the middle symbol, and the right symbol are stopped is performed, and the process number is changed to a normal process number. Step S28: Fanfare Processing In the fanfare processing, processing for displaying the fanfare on the special symbol display device 4 for a predetermined time is performed, and when the fanfare display is completed, the processing number is changed to the number of the jackpot processing.

Step S30: Big hit process (details will be described later in a subroutine) In the big hit process, a process for performing a special game (a game in which the special variable winning device 5 is opened) is executed. Is changed to the processing number. In the big hit process, for example, in order to perform a special game (a game for shortening the fluctuation time of the fluctuation display game of the general figure), the time reduction counter of the general figure is set to, for example, 50 times depending on the result of the display game during the big hit. May be performed. During the big hit state, as described above, the normal time reduction control is performed, and the normal power (normal fluctuation winning device 6) is frequently opened, so that the number of balls acquired during the big hit increases, which is more advantageous to the player. become. Step S32: Big hit ending processing In the big hit ending processing, processing for ending the big hit state is performed, and the processing number is changed to the normal processing number. In addition,
Branch processing by the above process numbers (steps S18 to S3
According to 2), every time the sequence of the main routine is repeated, the processing number is changed according to the gaming state.

Next, in the main routine shown in FIG. 3, after the above branch processing is performed, then, in step S34.
, Perform external information processing, and perform processing related to transmission and reception of information with the management apparatus 201. Next, a big hit random number update process is performed in step S36. As a result, first, the random numbers of the special figure and the general figure are incremented by, for example, [1] and updated. Therefore, each time this routine is repeated, the random numbers of the special figure and the ordinary figure change, and the random number extraction value per the big hit or the ordinary figure maintains the randomness. The random number for reach generation is maintained by incrementing and updating the reach generation random number by, for example, [1].
Here, there are fifteen types of random numbers for reach generation, for example, 1 to 15, where one random number generates a reach and the remaining 14 random numbers do not generate a reach. Therefore, the reach occurrence probability is 1/15.

Next, in step S38, a stopped symbol creation process is performed. This usually creates a stop symbol at random, but a probability variation symbol (hereinafter simply referred to as a probable variation symbol).
When a big hit occurs in the game, the current variable pattern is stored as the variable pattern deletion data (refer to the subroutine of the large hit processing described later). This is for creating a design. Next, a display symbol editing process is performed in step S40. As a result, a process relating to editing of the display pattern of the special figure is performed. Next, in step S42, a data transfer process is performed, and the display control circuit 2
00 necessary data is transferred. Thereby, for example, the editing result data of the display pattern of the special figure is transferred to the display control circuit 200. Next, an output process is performed in step S44. As a result, for example, a signal is output to various decorative lamps (for example, the side lamp 8c), and a decorative effect is performed. After step S44, the main routine 1
The sequence ends.

(B) Regular Processing FIG. 4 is a flowchart showing a subroutine of the regular processing in step S18 in the main routine described above.
When this subroutine is started, first, in step S50
To determine whether there is a start memory. The start memory means a state in which there is a prize in the ordinary variable prize winning device 6, the prize state is stored, and the state becomes an effective state in which the change of the special figure can be started. If there is no start memory, the current routine is terminated and the process returns to the main routine. On the other hand, if there is a start memory, the flow advances to step S52 to decrement the start memory by "1". Thereby, the lighting number of the special figure start storage display 4c is reduced by one, and the player is notified that the special figure has started to change due to the start memory and the number of stored figures has decreased. Next, in step S54, it is determined whether or not the probability variation counter is 0. The probability variation counter counts how many times a big hit is likely to occur after the big hit is completed and a big hit is generated after the big hit is completed, when a big hit occurs due to the probability change symbol. In the present embodiment, when a big hit occurs due to the probability change symbol, the big hit probability is changed by setting three big hits including the big hit as one set.

If the probability variation counter is equal to 0 in step S54, the flow branches to step S56 to select a random number judgment value (for example, one judgment value) in the normal probability, and then proceeds to step S60. Therefore, at this time, the jackpot probability does not increase and is a normal probability (for example, 1/300). On the other hand, when the probability variation counter is not 0 in step S54 (for example, the probability variation counter = 2 or the probability variation counter =
In the case of (1), the process proceeds to step S58 to select a random number judgment value (for example, 10 judgment values) whose probability is being increased, and then proceeds to step S60. Therefore, at this time, the jackpot probability is increased (for example, 10/300), and the jackpot is easily generated.

In step S60, the extracted random number is compared with a jackpot determination value, and in step S62, it is determined whether the extracted random number is a hit value. If the extracted random number is not a hit value, the process proceeds to step S64 to determine whether or not the reach random number is a reach occurrence value. If the reach random number is a reach occurrence value, a stop-off-reach symbol is determined in step S66, and a reach flag is set in step S68. When the reach flag is set, the reach scroll of the special figure is performed in the symbol stop process of step S22 in the main routine. As a result, even if the extraction of the big hit is missed, a game in which the game is stopped at the missed symbol after the reach has occurred is performed. After step S68, the process number is changed to the change start process in step S70, and the current routine ends. As a result, in the next main routine, it is determined that the process branches to the variation start process by the process NO branch.

If the reach random number is not the reach occurrence value in step S64, a departure stop symbol is determined in step S72, and the flow advances to step S70. As a result, a game in which the game is stopped in a deviated pattern without occurrence of a reach is performed. On the other hand, if the large random number is a hit value in step S62, the process proceeds to step S74 to determine whether the probability is changing. If the probability is not changing, step S7
At 6, a big hit stop symbol is randomly determined. in this case,
The probability that the big hit stop symbol is determined to be the probable change symbol is 1/3. Next, the process returns through the processing of steps S68 and S70. As a result, after the reach scroll of the special figure is performed, the game stops at the randomly determined big hit stop symbol.

If the probability is fluctuating in step S74, the flow branches to step S78 to determine a big hit stop symbol based on the probable variable symbol deletion data. This is to determine a big hit stop symbol by a symbol excluding the symbol once assembled from the probability variation symbols. Therefore, the once-changed probability change symbol is deleted, so that the jackpot probability decreases, and as a result, the occurrence of the probability change state is continuously suppressed a plurality of times. After step S78, the process returns to step S68 and step S70.

(C) Stop symbol determination processing FIG. 5 is a flowchart showing a subroutine of the stop symbol determination processing of step S24 in the above-described main routine. When this subroutine is started, first, the reach flag is cleared in step S100, and step S10
At 2, a stop symbol is determined. Next, in step S104, it is determined whether or not the stopped symbol is a big hit symbol. If the symbol is a missing symbol, the process branches to step S106 to change the process number to the missing process and ends the current routine. As a result, in the next main routine, it is determined that the process branches to the disconnection process at the branch of the process NO.

On the other hand, if the stopped symbol is a big hit symbol in step S104, the process proceeds to step S108 to determine whether or not the probability variation counter is zero. If the probability variation counter is not 0 (that is, if the probability variation is already in progress), the process proceeds to step S110, where the probability variation counter is updated by [−1] (that is, decremented). Go) and proceed to step S112. Thereby, the remaining number of times of the jackpot probability change is reduced by one. For example, when the probability variation counter = [2], the probability variation counter is reduced to [1], and the probability variation counter = [1].
In the case of [1], the probability fluctuation counter = [0]. If the probability fluctuation counter is already 0, the process jumps from step S110 and proceeds to step S112. Step S11
In step 2, the process number is changed to the fanfare process, and the current routine ends. As a result, in the next main routine, it is determined that the process branches to the fanfare process at the branch of NO.

(D) Big hit processing FIG. 6 is a flowchart showing a big hit processing subroutine of step S30 in the above main routine. When this subroutine is started, first, in step S
At 150, the special variable winning device 5 is opened. Thereby, the special winning opening solenoid is excited and the special variable winning device 5 is opened, which is in a state advantageous to the player. Next, a count winning is checked in step S152.
The count winning means that when the special variable winning device 5 is opened, a ball wins in the special variable winning device 5 and is counted by one of the count switch 5d and the continuation switch 5c. Next, step S15
Check the V prize at 4. The V prize means that a ball wins in a so-called V prize opening arranged in the special variable prize winning device 5,
It is detected by the continuation switch 5c. This is a condition for the continuation of the big hit cycle.

Next, the count winning information is set in step S156, and the continuation number information is set in step S158. This is to set information in order to display count winning information and continuation number information on the display unit 4a (for example, LCD) of the special symbol display device 4. Next, in step S160, it is determined whether or not the jackpot round end condition (ie, one cycle end condition) is satisfied. The round end condition is, for example, 29.
It means that the number of balls reaches a certain number (for example, 10) whose count is regulated for 5 seconds, and the special winning opening solenoid is excited and the special variable winning device 5 is opened until the round end condition is satisfied. If the round end condition is not satisfied, that is, 29.5 seconds have not elapsed since the special variable prize winning device 5 was opened, or the special variable prize winning device 5 has won a certain number of balls whose count is limited. If not, this routine is ended and the same loop is repeated. When the round end condition is satisfied, the process proceeds to step S162 to close the special variable winning device 5. As a result, the special winning opening solenoid is de-energized, and the special variable winning device 5 is closed, which is disadvantageous for the player.

Next, in step S164, it is determined whether a continuation condition is satisfied. The continuation condition means that the above-mentioned V prize is won. If the continuation condition is satisfied, the process proceeds to step S166 to perform an interval process, terminates the current routine, and returns to the main routine.
In the interval processing, an interval between the big hit rounds is produced by displaying that an interval is being made between big hit rounds (between cycles) or by outputting a sound effect corresponding to the interval. When the interval processing is completed, the above-described processing is repeated in the next and subsequent routines on condition that a V prize is won. If the continuation condition is not satisfied in step S164, for example, the so-called puncture or the maximum number of jackpot rounds (16 times) is reduced. If the processing has been completed, the process proceeds to step S168.

In the step S168, it is determined whether or not the big hit in the probability variation symbol has ended. The symbols “1”, “3”, “5”, “7”, and “9” are set as the probability variation symbols. If the big hit in the probability variation symbol ends, in step S170, [2] is set in the probability variation counter, and the process proceeds to step S172. As a result, when a jackpot occurs due to the probability variation symbol, the jackpot probability fluctuates (ups) as a set of three jackpots including the jackpot. On the other hand, if the big hit in the probability variation symbol has not ended, the process jumps to step S170 and proceeds to step S172. In the step S172, it is determined whether or not the probability fluctuation counter = 0. This is to determine whether or not the probability variation counter is [2] or [1] (whether there is a remaining number of large hit probability variations). If the probability variation counter is not 0, the process proceeds to step S174, and it is determined whether or not the current big hit is a big hit with a probable variable symbol.

If the current big hit is a big hit with a probable variable design, the current probable pattern is stored as probable variable deletion data in step S176. Thereby, in the processing of step S78 in the usual processing, the big hit stop symbol is determined based on the probable change symbol deletion data. Is determined, and once the probability variation symbol is deleted, the probability of occurrence of the probability variation symbol decreases. In addition, the control of determining the big hit stop symbol by the symbols excluding the once aligned symbols among the probable symbols is to control the occurrence of the special stop mode related to the specific symbol once generated to be converted to the invalid state. Equivalent to.

Next, at step S178, certain change deletion symbol information is set. This is to set information in order to display a symbol with a possibility of a big hit on the display unit 4a (for example, LCD) of the special symbol display device 4 in order to display the symbol excluding the surely deleted symbol. (See FIG. 8). As a result, the player can easily recognize the surely deleted symbol. Next, in step S180, the process number is changed to the big hit end process, and the current routine ends.
As a result, in the next main routine, it is determined that the process branches to the jackpot ending process by branching with the process NO. On the other hand, if it is not a jackpot in the probable change symbol in step S174, the process jumps from step S176 and step S178 to proceed to step S180. Therefore, if the current big hit is not a big hit by the probable change symbol, the design is not deleted, and the probability of appearance of the probabilistic change design is not changed from the previous time.

In step S172, the probability fluctuation counter = 0
If it is, it is determined that there is no big hit by the normal symbol or the number of remaining big hit probability changes, and step S182 is performed.
Go to to clear the probable variable deletion data. As a result, once-deleted probable pattern deletion data is lost,
Again, it will be added to the jackpot symbol. Therefore, the probability of appearance of the probability change symbol returns to the initial state. Then
In step S184, initial symbol information is set. Thereby, the display unit 4a (for example, LC
In D), the initial symbol information (that is, all the special figures) in which a big hit may occur is displayed. Step S18
After step 4, the process proceeds to step S180 to change the process number to the jackpot end process, and ends the current routine.

E. Specific Example of Deletion of Probable Variation Symbol Next, a specific example of control for deleting a probable variation symbol once prepared to reduce the probability of occurrence of probability variation (establishment rate of large hit) will be described with reference to FIGS. 7 to 9. FIG. 7 is a diagram for explaining a state in which the big hit symbols are sequentially deleted, FIG. 8 is a diagram showing the display contents of the special symbol display device 4 when a certain big hit occurs, and FIG. FIG. (A) Normal time Normally, as shown in FIG. 7 (a), there are 15 types of symbols (special figures) from "0" to "E".
There is one for each of the left, middle, and right columns. Of these, five symbols “1”, “3”, “5”, “7”, and “9” are probable symbols and are displayed in black. Normal symbols are displayed as white symbols. Therefore, the appearance rate of the probability variation symbol (that is, the probability variation occurrence rate) is 5/15.

(B) First big hit (big hit with "3") First, as shown in FIG. 9, when the big hit with "3" occurs as the first big hit, FIG. 8 (a) "3", "3", "3" are displayed on the special symbol display device 4 as shown in FIG.
Are displayed, and the display "Probable change big hit start" is displayed. Then, a big hit game is played. Next, when the jackpot with the probable variable symbol “3” ends, the probable symbol “3” is deleted after the end of the jackpot, and the jackpot symbol is determined in a state where the probable symbol “3” is deleted as shown in FIG. Will be performed. Therefore, there are four likelihood change symbols, “1”, “5”, “7”, and “9”, and the value (total number) obtained by subtracting 1 from the total number (= 15) of special figures (in other words, special figure random numbers) -1 = 14), and the probability of occurrence of probability change is 4/1.
It becomes 4.

In this case, in the game after the big hit with the probable variable symbol “3” is completed, the special symbol display device 4 displays FIG.
As shown in (b), "1st time 3" is displayed, and the success of the big hit is the first time, and that the previous big hit symbol is "3" is displayed, and the player is notified. Also, at this time, the special symbol display device 4 displays “Sure change remaining 2
Is displayed, and the remaining valid big hit symbols from which the probable variable symbol "3" has been deleted are displayed. Note that only the probable symbol is circled. Therefore, the player has determined that the last big hit symbol is "3", that the last big hit symbol "3" has been deleted, that the last two big hit symbols have been changed, and that all remaining valid big hit symbols are called. Information can be easily recognized.

(C) Second Big Hit (Normal Big Hit) Next, as shown in FIG. 9, as the second big hit, if a big hit with a normal symbol occurs, even if the big hit game ends, the normal big hit is not changed. The jackpot symbol is determined in the same state as when the probability variable symbol “3” is deleted as shown in FIG. 9 without being deleted. (D) Third big hit (big hit with probable variable symbol “7”) Next, as shown in FIG. 9, when a big hit with probable variable “7” occurs as the third big hit, the special symbol display device 4 displays “7”. , "7", and "7" are aligned, and the display "Probable change big hit start" is displayed. Then, a big hit game is played. Next, when the jackpot with the probable change symbol “7” ends, the probable change symbol “7” after the end of the jackpot.
Is deleted, and the big hit symbol is determined in a state where the positively-variable symbol "7" is deleted as shown in FIG. 7 (c). Similarly, the special figure random number corresponding to the total number of jackpot symbols is the total number (= 1
5) minus 2 (total number−2 = 13). Therefore, there are three probability variation symbols “1”, “5”, and “9”, and the total number of special figure random numbers is a value obtained by subtracting 2, so that the probability variation occurrence rate is 3/13.

In this case, in the game after the big hit with the probable variable symbol “7” is completed, the special symbol display device 4 displays FIG.
As shown in (c), "3rd 3 8 7" is displayed, and the success of the big hit is the third time (that is, the third time of continuation), and the big hit symbols so far are "3" and "8". , "7" is displayed and the player is notified. At this time, the special symbol display device 4 displays "2 remaining probable changes" and the remaining valid big hit symbols from which the probable changes "3" and "7" have been deleted. Therefore, the player has determined that the previous big hit symbols are "3", "8", "7", that the last big hit symbols "3" and "7" have been deleted, In fact, it is possible to easily recognize the information of all the remaining valid big hit symbols. In addition, during the probability change game, if, for example, a big hit is again made with the probability change symbol “7”, the probability change game is valid again, and the probability change game in which three big hits constitute one set occurs repeatedly. For example, while a jackpot is generated by the probable symbol "3" and the jackpot probability is increased until two more jackpots are generated, as shown in FIG.
The change of the jackpot probability with the number of jackpots as one set is started again. That is, the change of the jackpot probability in which the three jackpots are set as one set continues continuously.

(E) Fourth big hit (big hit with probable change symbol "5") Next, as shown in FIG. 9, when a big hit with positive change symbol "5" occurs as shown in FIG. "5", "5", and "5" are aligned, and the display "Probable change big hit start" is displayed. Then, a big hit game is played. Next, when the jackpot with the probable design "5" ends, the probable design "5" is used after the end of the jackpot.
Is deleted, and the big hit symbol is determined in a state where the positively-variable symbol “5” is deleted as shown in FIG. 7D. Similarly, the special figure random number corresponding to the total number of jackpot symbols is the total number (= 1
5) minus 3 (total number−3 = 12). Therefore, there are two probability variation symbols “1” and “9”, and the total number of special figure random numbers is a value obtained by subtracting three.
It becomes 2/12.

(F) Fifth Big Hit (Normal Big Hit) Next, as shown in FIG. 9, as the fifth big hit, if a big hit with a normal symbol occurs, the normal big hit is not changed even if the big hit game is ended. The jackpot symbol is determined in the same state as when the probable variable symbols “3”, “7”, and “5” are deleted as shown in FIG. 9 without being deleted. (G) Sixth Big Hit (Normal Big Hit) Next, as shown in FIG. 9, as the sixth big hit, if a big hit by the normal symbol occurs, the normal symbol is not deleted even if the big hit game ends. Then, the big hit symbol is determined in the same state as when the probable variable symbols "3", "7", and "5" are deleted. Then, the change of the jackpot probability in which three jackpots by the probable variable symbol “5” are set as one set ends, and the jackpot probability returns to normal again.

As described above, in the examples of FIGS. 7 to 9, when a big hit occurs in the probable change symbol, the probable change pattern once arranged after the end of the big hit is deleted, and the next big hit design is determined. In this case, since the once-variable symbols are excluded from the determination of the big hit symbol, the probability of occurrence of the probability-variable symbols decreases. Therefore, a big hit is more likely to occur during the probability fluctuation than in the normal case, but the rate of occurrence of the big hit in the positively-variable design decreases, and the rate of occurrence of the big hit in the normal design increases. As a result, it is possible to reduce the number of games in which the jackpot is once again hit with a probable variable symbol during the probability change and the jackpot is generated twice from that point. That is, it is possible to suppress the occurrence of the probability fluctuation state from continuing continuously plural times.
For example, it is possible to eliminate the case where a large hit occurs continuously many times (for example, several tens of times) as in the related art. Therefore, it is possible to balance the profit between the player and the game store, and to provide a gaming machine that can be enjoyed by many players.

Further, the probability variation pattern (probability of winning the probability variation) is reduced by deleting the probability variation symbol once prepared, so that it is possible to suppress the occurrence of the probability variation state from continuing continuously a plurality of times. As in the past, the award rate of game balls to the special map starting winning opening in the game store, for example, extremely lowered by nail adjustment, or the probability set value of the big hit, the gaming machine manufacturer also reduced the probability value This eliminates the need to manufacture a machine with a reduced initial set value. As a result, a game with a high level of gambling, such as not having a big hit (that is, a risk of inducing a great loss to the player) or once a big hit has occurred in the probability-variation symbol, a large number of game balls can be obtained. Performance (high gambling)
Can be suppressed. Furthermore, since the control of suppressing the occurrence of the probability fluctuation state a plurality of times is performed while allowing the big hit by the probability fluctuation symbol, the suppression of the gambling spirit while maintaining the fun of the pachinko game for the player is performed. A gaming machine can be obtained which simultaneously achieves both gaming performances that can be enjoyed by many players. In particular, as in the present embodiment, a control for determining a big hit stop symbol by a symbol excluding the once-aligned symbol from the probability change symbols (converts the occurrence of the special stop mode related to the specific symbol once generated to an invalid state). Control), the once-possible variable design is erased, the next variable game is performed, the continuation of the probability fluctuation state can be reliably suppressed, and the suppression control (display control) that is satisfactory to the player. Can be

F. Second Embodiment Next, FIG. 10 is a diagram showing a second embodiment of the present invention, in which control is performed to reduce the random numbers for randomly selecting a probable symbol during probable variation. In the second embodiment, since the contents of the subroutine of the ordinary processing are different from those of the above-described embodiment, and the others are the same, the subroutine of the ordinary processing will be described. FIG. 10 is a flowchart showing a subroutine of a usual process. In the description of the subroutine, steps for performing the same processes as those in FIG. 4 of the first embodiment will be denoted by the same step numbers, and redundant description will be omitted. Will be described with reference to different step numbers.

When the subroutine of FIG. 10 is started, the processing of steps S50 to S62 is the same as in the first embodiment. Next, if the decision result in the step S62 is NO, the process branches to a step S64, and the subsequent processes (steps S64 to S72) are the same as those in the first embodiment. If the decision result in the step S62 is YES (that is, if the extracted random number of the big hit is a hit value), the process proceeds to a step S200 to extract the random variable for determining the probability change. The probability-change random number is a random number for determining whether or not the probability is changed after a big hit occurs. For example, 15 types of random numbers from “0” to “14” are used.
Therefore, in step S200, one probable-change random number is extracted from 15 types. Next, step S2
At 02, it is determined whether or not the probability is fluctuating. If the probability is not fluctuating, the process proceeds to step S204, and a normal determination value (five in this case) is selected as the determination value for determining the probable symbol. Therefore, when the probability is not fluctuating, the probability variation symbol is drawn at a rate of 5/15. On the other hand, step S20
If the probability is changing in step 2, the process proceeds to step S206, and the determination value during the probability change (here, three) is selected as the determination value for determining the probability variation symbol. Therefore, when the probability is changing, a probability change symbol is drawn at a rate of 3/15.

Step S204 or step S20
After step 6, the extracted value of the probability-change random number is compared with the determination value for determining the probability-change symbol in step S208 to determine whether or not it is a hit value. This is performed by comparing the extracted value of the probability change determination random number with a normal determination value (here, five) or a determination value during probability change (here, three). At this time, if the probability is fluctuating, the determination values (three) during the probable change are selected, so that the winning value (the probable change symbol is subtracted) is 3/15. On the other hand, if the probability is not fluctuating, the normal judgment values (5) are selected, so that 5/1
The winning value (usually a symbol is subtracted) is obtained at a rate of 5.

If the result of the comparison between the extracted value of the probability variation determining random number and the determination value for determining the probability variation symbol is a hit value, step S2
The determination result of 08 is YES, the process proceeds to step S210, and the big hit symbol is determined by the positively changing symbol. As a result, when the next big hit occurs, the process shifts to the probability variation. If the comparison result between the extracted value of the probability variation determining random number and the determination value for determining the probability variation symbol is not a hit value, step S2
The determination result of 08 is NO, the process proceeds to step S212, and the big hit symbol is determined by the normal symbol. Thus, when the next big hit occurs, the process does not shift to the probability fluctuation. After step S210 or step S212, steps S68 and S70 are executed and the routine returns. In the second embodiment, the probable-variation-determining random numbers are extracted in step S200. However, the probable-variation-determining random numbers may be extracted, for example, at the time of the start winning, instead of being performed at this timing. In addition, the probability of occurrence of probability change symbols during probability change is 3/1.
In addition to fixing to 5, each time the probability change count increases,
The occurrence rate of the probability variable symbol may be reduced from 3/15 to 2/15. Or, every time a probable symbol appears during probabilistic
The occurrence rate of the probable change symbol may be reduced to / 15 → 3/15 → 2/15.

As described above, in the second embodiment, if the random number for extracting the big hit is a hit value, the probability-change random number is extracted. If the probability is fluctuating, the probability-change random number is extracted at a rate of 3/15. Is the hit, and if the probability is not fluctuating, the result of extraction of the probabilistically determined random number is a hit at a rate of 5/15. Therefore, the occurrence rate of the probability variation symbol decreases during the probability variation as compared with the normal state. As a result, as in the first embodiment, it is possible to reduce the number of games in which a large hit is made again with a probability change symbol during the probability fluctuation, and two big hits are generated again from that point. That is, it is possible to suppress the occurrence of the probability fluctuation state from continuing continuously plural times.

G. Third Embodiment Next, FIG. 11 is a diagram showing a third embodiment of the present invention. In this embodiment, the occurrence of the probability fluctuation and the number of times of the probability fluctuation are determined by another game without determining the probability fluctuation by a special figure. In the third embodiment, a pachinko game having the control contents shown in FIG. 11 is performed. First, as shown in FIG. 11A, when a big hit occurs at the symbol “3”, the special symbol display device 4 displays “3”,
"3" and "3" are aligned, and "Big hit" is displayed. Then, a big hit game is played. Next, immediately after the symbol "3" is prepared, another game (corresponding to an auxiliary variable game performed in connection with the occurrence of the special game state) is performed using the variable display section 4a of the special symbol display device 4. Note that, after the end of the big hit, another game may be played using the variable display section 4a of the special symbol display device 4.

In another game, a predetermined random number is used, and FIG.
As shown in (b), a game for determining whether to determine the probability change and a game for determining how many times the probability change is to be performed when the probability change is determined are performed. In this case, suppression control of the probability fluctuation continuation is performed. For example, a random number for determining the occurrence of the probability change and the number of continuations is provided. Control is performed to reduce to 1/5 or the like. In addition, the probability that the stop symbol “probable change” that determines the probable change appears on the image displayed on the fluctuation display unit 4a of the special symbol display device 4 is also reduced. Similarly, the random number control is performed so that the ratio of the number of continuations displayed as “once” increases during the probability change.

Here, when the probability change is determined as a result of the separate game, a display indicating that the probability change is determined and the number of times of the probability change = 1 is displayed as shown in an example of FIG. If the probability change is not determined, a message indicating "out of place" or "normal" is displayed. In addition, the number of times of change is, for example, 2
There is a decision of times. In the example of FIG. 11, the special symbol display device 4 is used for another game. However, instead of using the special symbol display device 4, another display (for example, a 7-segment display) is used. You may play another game.

As described above, in the third embodiment, the probability variation and the number of the probability variation are determined by another game without determining the probability variation based on the special figure. During the probability change, random number control is performed to reduce the probability of the probability change to 1/5 or the like. Therefore, during the probability fluctuation, the probability of occurrence of the probability fluctuation symbol is lower than that at the normal time, and as in the first embodiment, during the probability fluctuation, the probability change symbol hits again and the big hit occurs again from that point twice. The number of games to be played can be reduced. That is, it is possible to suppress the occurrence of the probability fluctuation state from continuing continuously plural times. In addition, since the occurrence and the number of the probability fluctuations are determined in a game different from the special figure, the probability fluctuation state can be surely suppressed, and since the game is different from the special figure, It is also possible to improve the interest. Note that the probability of occurrence of the probability change during the probability change may be gradually reduced according to the number of times the probability change is continued.

H. Fourth Embodiment Next, FIGS. 12 and 13 are diagrams showing a fourth embodiment of the present invention, in which an upper limit value of the number of continuous probable changes is provided. In the fourth embodiment, the contents of the subroutine of the ordinary processing are different from those of the above embodiment, and the other parts are the same. Therefore, the subroutine of the ordinary processing will be described. FIG. 12 is a flowchart showing a subroutine of a normal process. In the description of the subroutine, steps for performing the same processes as those in FIG. Will be described with reference to different step numbers.

When the subroutine of FIG. 12 is started, the processing of steps S50 to S62 is the same as in the first embodiment. Next, if the decision result in the step S62 is NO, the process branches to a step S64, and the subsequent processes (steps S64 to S72) are the same as those in the first embodiment. If the result of the determination in step S62 is YES (that is, if the extracted random number of the jackpot is a hit value), the process proceeds to step S300 to determine a jackpot symbol at random, and in step S302, is the determined jackpot symbol a probable variable symbol? It is determined whether or not. Therefore, at this stage, the probability of occurrence of the probable change symbol is the same as the conventional one. If the big hit symbol is a probability variation symbol, the process proceeds to step S304 to extract a random number for determining a probability variation. Here, the random number for determining the probability variation is
For determining the number of probable changes, for example, "0" to
There are four types of "3", the breakdown of which is as follows.

Random number “0” for determining probability change: two times of probability variation (three big hits including the first time) Random number for probability determination “1”: three times of probability variation (four times including the first time)・ Random number for determination of probability change “2”: 4 times of probability change (total of 5 big hits including the first time) ・ Random number for determination of probability change “3”: 5 times of probability change (total of 6 times including the first time) Next, in step S306, the number of probable changes is determined based on the extracted random number result. For example, a random number for determining a probability change = “0”
Is extracted, the probability change times are determined twice. In this case, the number of times of probability change is restricted to five at the maximum. Then, step S
The probability change information determined in step 308 is set, and step S6
Proceed to 8. Thereby, the display unit 4 of the special symbol display device 4
a indicates the probability change information (that is, the determined value of the number of times of probability change based on the extracted random number result (for example, twice)). There is no update of the number of probable changes. Therefore, unless a plurality of jackpot games based on the determination of the number of probable random changes based on the extracted random number result have been completed, the number of probable variations based on the next extracted random number result is not determined.

FIG. 13 is a view showing a display example of the special symbol display device 4 in the fourth embodiment. First, as shown in FIG. 13 (a), when a big hit occurs at the probable symbol "3", the special symbol display device 4 has "3", "3", and "3", and the "probably big hit" occurs. Is displayed. And
A jackpot game is played. Next, immediately after the probability change symbol “3” is prepared, another game (corresponding to an auxiliary variable game performed in connection with the occurrence of the special game state) is performed using the variable display section 4a of the special symbol display device 4. Note that, after the end of the big hit, another game may be played using the variable display section 4a of the special symbol display device 4. In another game, the random hits "3", "3", and "3" hit this time are displayed as shown in FIG. 13B using random numbers "0" to "4" for determining the random change. , "Probable change count is being determined" is displayed,
A game in which the number of probable changes is determined within a predetermined upper limit (here, five times) is performed. In this case, the control for suppressing the probability fluctuation continuation is performed, and the control is performed such that the probable change is continued only five times at the maximum. Then, as a result of another game, when the probability change is determined, it is displayed that the probability change frequency is determined as “3 times” as shown in an example in FIG.

As described above, in the fourth embodiment, when the random number for extracting the big hit is a hit value, if the big hit symbol is a stochastic symbol, the random number for determining the stochastic change is extracted, and the number of times of the stochastic change is 5 at the maximum. Decide within the times. Therefore, it is possible to suppress the occurrence of the probability fluctuation state from continuing continuously a plurality of times, and in particular, to eliminate the case where the big hit occurs continuously many times (for example, several tens of times) as in the related art. Can be. The occurrence of the probability fluctuation state can be restricted to at most five times.

The embodiments of the present invention are not limited to the above-described embodiments, and various modifications as described below are possible. (A) It can be applied to pachislot machines. (B) The present invention is applicable not only to pachinko gaming machines but also to, for example, video game machines. That is, even in the case of a video game machine, a plurality of identification information items are variably displayed on a plurality of columns of variable display units, and the result of the variable display game on the plurality of columns of variable display units is a predetermined special stop mode. Sometimes, a special game state (for example, a big hit state) can be generated, and when the generation of the special game state satisfies a specific condition, the generation of the special game state is converted to an easy state. (For example, a state in which the jackpot probability fluctuates), and a special game state that satisfies a specific condition again occurs during a state where the special game state is easily generated (for example, during a probability change game) (for example, In the case where a big hit occurs again due to the probability variation symbol, the state where the special game state is easily generated continues (for example, three big hits are set as one set, and two big hits are generated after the first big hit). ) It can be applied as long as it is the ability.

(C) Further, according to the present invention, a plurality of identification information is variably displayed on a plurality of columns of variable display units, and the result of the variable display game of the plurality of columns of variable display units is a predetermined special stop mode. Sometimes, a special game state can be generated, and when the special game state is generated that satisfies a specific condition, the special game state is converted to an easy state, and the special game state is generated. When a special game state that satisfies a specific condition occurs again (for example, when a big hit occurs again with a probability change symbol) during a state where the game is easy (for example, during a probability change game), the special game Continuous occurrence of a state where the state is easy to occur (for example, three hits
As a set, it goes without saying that any type of gaming machine may be used as long as it enables the game to generate two big hits after the first big hit. For example, other types of pachinko machines, arrange ball machines, sparrow ball game machines,
It can also be applied to slot machines and the like.

(D) The present invention is not limited to the control contents as in the above embodiments, but various modifications as described below are possible within the scope of the present invention. Normally, probability fluctuation occurs at an incidence of 1/3, and then 2
Control may be performed such that the probability fluctuation is continued until the round jackpot occurs, the probability of occurrence of the probability change symbol is reduced to 1/5 during the probability fluctuation, and the probability fluctuation frequency is limited to one after the first time. . According to this, while leaving the fun of probability fluctuation occurrence,
It is possible to limit the number of changes in probability. For example, when a probability change occurs, the probability change is continued until two big hits occur thereafter, and the continuation of the probability change is effective only at the last big hit (third big hit) of the two big hits. Control may be performed. In addition, even if the first (second) big hit time during the probability change is the probability change pattern,
From that point, the probability fluctuation is not continued. According to this, it is possible to prevent a large number of continuous fluctuations in probability.

As the number of continuations of the probability change increases,
By reducing the number of counts, the number of rounds, the number of prize balls, and the like of the special fluctuation prize winning device 5 at the time of a big hit, even if the number of continuations of the probability fluctuation increases, it is possible to suppress the hitting of the big hit and suppress the ambition. Good. For example, the number of rounds is increased to 16R, 14R, 12
R,..., The count number is 10, 9, 8,.
Such control is performed. According to this, it is possible to suppress the player's acquired payout while maintaining the interest of the game that the probability fluctuation continues. In the above-described embodiment, when a large hit with a probability variable symbol is performed, for example, a method of deleting the symbol of “3” after a large hit with a variable probability symbol “3” is used. The symbol "3" may be left without being erased, and may not be a positively changed symbol thereafter. In that case,
The symbol of "3" is changed from a black symbol (a probable symbol) to a white symbol (a normal symbol), and notifies the player that the symbol is no longer a probable symbol. According to this, since the type of the symbol does not change, the interest of the game can be maintained while suppressing the continuation of the probability fluctuation. Alternatively, the symbol "3" may be left without being erased, and the same symbol may not be displayed during the probable change by the internal control.

In the above embodiment, the control for suppressing the probability fluctuation is performed simultaneously with the start of the probability fluctuation (always during the fluctuation of the probability). ), Control for suppressing the probability fluctuation may be started. By doing so, it is possible to more finely suppress the continuation of the probability fluctuation without changing the interest of the probability game. The probability variation occurrence rate may be changed each time the probability variation number increases. For example, normally, the probability of occurrence of probability fluctuation = 1/3
00, the probability change probability is the first occurrence of probability change = 10/30
0, the probability change probability is 8/300,
... may be changed as follows. Further, such control may be performed together with control for suppressing the number of times of change in probability.
According to this, it is possible to maintain the fun of the game while suppressing the probability fluctuation more finely.

The maximum value of the number of times of probability change is set to, for example, five (but no re-continuation). If a big hit occurs in the symbol “7”, a big hit occurs five times in the symbol “3” and a big hit occurs in the symbol “3”. The probability variation may be restricted according to the type of the big hit symbol, such as four times of probability fluctuation in the case of a large hit, three times of a large hit in the case of a symbol "5", and so on. . According to this, depending on the type of the symbol at the time of the occurrence of the big hit, it is possible to give the player a sense of expectation such as being excited. When the number of times of the probability fluctuation of the special figure reaches a predetermined value (for example, five times), the control may be switched to the probability fluctuation control of the general figure or the time reduction control of the general figure. According to this, the gambling property can be suppressed in the ordinary figure, and the game content can be diversified.

【The invention's effect】

(1) According to the first aspect of the present invention, when a special game state that satisfies a specific condition again occurs while the special game state is easily generated (for example, during a probability variation game) ( For example, in the case where a big hit occurs again due to the probability variation symbol, a state in which the special game state easily occurs is continuously generated (for example, three big hits are set as one set, and two more big hits are performed after the first big hit). Occurrence) is possible, and the continuation rate of the state where the special game state is easily generated (probability fluctuation game state) is changed to the establishment rate of specific conditions (probability fluctuation pattern,
For example, since the suppression control is performed by changing the “7”, “7”, and “7” establishment rates), the following effects can be obtained. Even if a specific condition is satisfied again (for example, a big hit with a probable change symbol) during a state where the special game state is easily generated (for example, during a probability change game), the special game state (for example, a big hit) is re-started from that point on Games in which the game occurs twice can be reduced. In other words, it is possible to prevent the state where the special game state is easily generated (for example, the probability fluctuation state) from continuing continuously plural times. For example, a large number of hits as in the past (for example,
(Several tens of times) It is possible to eliminate the case of continuously occurring. Therefore, it is possible to balance the profit between the player and the game store, and to provide a gaming machine that can be enjoyed by many players.

Further, it is possible to suppress the occurrence of a state in which the special game state is easily generated (for example, a probability fluctuation state) from continuing continuously a plurality of times.
The award rate of the game ball to the special map starting winning opening in the amusement store is extremely lowered, for example, by adjusting the nail, or the probability setting value of the jackpot is reduced, and the gaming machine manufacturer also lowers the default value of the probability value. It is possible to eliminate the necessity of manufacturing a machine which is not used. As a result, if a special game state (for example, a big hit) does not easily occur (that is, there is a fear of inducing a great loss to the player), or if a specific condition is satisfied (for example, a big hit occurs in a probable symbol), a large amount of Game performance (high gambling) with a high sense of gambling, such as being able to acquire the same game ball. Further, control for suppressing occurrence of a state in which a special game state is easily generated (for example, a probability fluctuation state) a plurality of times while allowing specific conditions to be satisfied (for example, occurrence of a big hit in a probable symbol). Therefore, it is possible to obtain a gaming machine that simultaneously achieves both the suppression of gambling and the gaming performance that many players can enjoy while maintaining the fun of the pachinko game for the player.

(2) According to the second aspect of the present invention, the specific condition is satisfied when a special stop mode (for example, a big hit) occurs in relation to a predetermined number of specific symbols (for example, a probable change symbol). Then, by suppressing the occurrence of the special stop mode related to the specific symbol at that time, it is possible to reliably suppress the continuation of the establishment of the specific condition (for example, the occurrence of the big hit in the positively-variable symbol). (3) According to the third aspect of the invention, the continuation suppressing means converts the occurrence of the special stop mode (for example, the big hit) related to the specific symbol (for example, the probable change symbol) once generated to the invalid state, Once the specified symbols are aligned, for example, erased and the next variable display game on the variable display device is performed,
It is possible to surely suppress the continuation of the establishment of the specific condition (for example, the occurrence of a big hit in a probable change symbol) and to perform the suppression control (for example, the display control) so that the player is satisfied. (4) According to the invention described in claim 4, the specific condition is established based on the result of the auxiliary variable display game performed in association with the occurrence of the special game state, thereby ensuring the specific condition. Satisfaction of the condition (for example, occurrence of a big hit with a probable change symbol) can be suppressed, and since the game is different from the variable display game on the variable display device, the interest of the game can be improved.
