For example, when the setting value of the setting switch 64 is “1”, the display probability of the big hit symbol at the time of low probability is “1/2”.
24, and similarly, when the set value is “2”, “1/248” is set, and when the set value is “3”, “1/272” is set. Of course, the probability at the time of high probability may be changed by the set value of the setting switch 64, or the probability of the low probability and the high probability of the ordinary symbol variable display 35 is also changed by the set value of the setting switch 64. May be.

On the other hand, a control signal is supplied from the basic circuit 50 to the following devices and circuits. That is, a sound signal is given to the speaker via the sound circuit 55. In addition, the numerical display 16 and the decorative pattern 3 via the segment / LED circuit 56

From 40c to 40c, input signals are sent to the basic circuits 59 and 51 via the sensor input circuit 62. Note that power having various voltages is supplied from the power supply circuit 63 to the above-described devices and circuits.

An example of a specific operation of the game control circuit described above will be described with reference to time charts and explanatory diagrams shown in FIGS. First, the operation of the ordinary symbol variable display 35 will be described with reference to FIGS. FIG. 5 is a time chart showing the operation of the ordinary symbol variable display 35 based on the passing of a hit ball to the passing openings 21a and 21b. FIG. 6 shows a case where the hit ball passes through the passing openings 21a and 21b. It is explanatory drawing explaining the selection method of the hit symbol determined. In the drawing, a hit ball passes through the passing ports 21a and 21b, and the passing ball detectors 22a and 22b are turned ON.
When the passing signal T1 is derived, one value is extracted from the random 4 when the passing signal T1 rises. As shown in FIG. 6, the random number 4 is a random number for determining whether or not a hit symbol is present. As shown in FIG. It is changing every moment. Also, after deriving the passing signal T1, 0.
When 002 seconds have elapsed, the stored value of random 4 is read, and when the read value of random 4 is not a hit, one value is extracted from random 5. This random 5
As shown in FIG. 16, 0 and 1 change for each interrupt processing and for each remaining time of the interrupt processing.
When 0 is extracted, “3” is displayed on the variable display for ordinary symbols 35 at the time of stop, and when 1 is extracted,
"F" is displayed.

When the numerical value extracted from the random 4 is, for example, "1", it is determined that a hit has occurred, and the specific display result "7" is displayed on the variable display 35 for ordinary symbols. On the other hand, when the numerical value extracted from the random 4 is other than the above, it is determined to be out of place, and the above-mentioned symbol corresponding to the value of the random 5 extracted at that time is displayed on the variable symbol display 35 for ordinary symbols. The above-mentioned determination of the hit or miss is at a normal probability time (hereinafter, referred to as a low probability time),
As described later, when the probability is changed (hereinafter, referred to as a high probability), when the value extracted from the random 4 is any one of “1 to 10”, it is determined that a hit has occurred. It is supposed to be. Therefore, the probability of a hit at the time of low probability is 1/15, while the probability of a hit at the time of high probability is 10/15.
This means that it has been changed to 0 times. The multiple at the time of high probability may be adjusted to an arbitrary value by the setting switch 64 or the like (another switch may be provided).

As described above, when the passing signal T1 is derived, it is determined whether or not the symbol displayed on the variable symbol display 35 is a hit, and the symbol displayed when the vehicle is stopped is also determined. After the determination is completed (in this embodiment, 0.002 seconds after the passage signal T1 is derived), the fluctuation of the ordinary symbol variable display 35 is started. Thus, the variation time at the low probability is set relatively long (25,000 seconds), and the variation time at the high probability is
It is set relatively short (7,000 seconds). This is because, when the probability is high, the hit is put out early,
To generate a lot of start winning prize balls, thereby continuously rotating the rotating drums 38a to 38c, in order to attract the interest of the player at a high probability.

As described above, the variable indicator 3 for ordinary symbols
7 and 8 show the game after the variable display has been stopped. FIG. 7 is a time chart showing the operation of the electric start winning port 6 when the stop symbol is a hit.
Is a time chart showing the operation of the electric start winning port 6 when the stop symbol comes off. Therefore, the case of the departure will be described first with reference to FIG. 8. After the variable display of the ordinary symbol variable display 35 is stopped, a minute time (0. .0
(02 seconds), if there is a passage memory, the normal symbol variable display 35 starts to change again.

Next, with reference to FIG. 7, a description will be given of the case of winning. When a fixed time (0.500 seconds) elapses after the variable display of the ordinary symbol variable display 35 is stopped, the electric start winning port. 6 is released until a certain time (3.000 seconds) elapses. However, if three winning balls are received during the opening, the opening is stopped even before the predetermined time has elapsed. Then, when the minute time (0.002 seconds) elapses after the opening of the electric start winning port 6, the normal symbol variable display 35 starts to change again if there is a passing memory.

When a ball hits the electric start winning opening 6 opened as described above, the rotating drums 38a to 38c start rotating. The operation will be described with reference to FIGS. FIG. 9 shows the start winning opening 5 and the electric starting winning opening 6.
12 is a time chart showing variable display control of the rotating drums 38a to 38c when a hit ball is won. FIG. 10 is an explanatory diagram illustrating a method of selecting a big hit symbol determined when a hit ball wins the start winning opening 5 and the electric start winning opening 6. However, FIG. 10 shows a case where the setting value is “2” when the setting switch 64 is provided. In the drawing, when a ball is won in the start winning opening 5 and the electric start winning opening 6 and the start winning ball detectors 8 and 9 are turned on and the start signal S1 is derived, a random 1 is generated when the start signal S1 rises. And one value is extracted from each of random 2 and random 3. The random number 1 is a random number for determining whether or not the symbol is a big hit symbol as shown in FIG. 10, and as shown in FIG.
The eight values fluctuate every moment. Random 2 is a random number for determining the arrangement pattern of the big hit symbols, and is set to “0 to 23” for each interrupt process after power-on and for each remaining time of the interrupt process. The random number 3 is a random number for determining a display pattern of a lost symbol, and is set to “0” for each interrupt processing after power-on and for each remaining time of the interrupt processing. ~ 5
5831 "are changing every moment.
Further, when 0.130 seconds elapse after the derivation of the start signal S1, the value stored at random 1 is read out, and further, 0.1
When 32 seconds have elapsed, the stored random 2 and 3 values are read out and one value is extracted from the random 6.
The random number 6 is a random number for determining the symbol displayed on the decorative symbol 34, and is not directly related to the game content.

When the numerical value extracted from the random 1 is, for example, "128", it is determined that a big hit has occurred, and a symbol array pattern corresponding to the random 2 value extracted at that time (see FIGS. 14 and 15 described later). Are displayed on the rotating drums 38a to 38c. On the other hand, random 1
When the numerical value extracted from the above is other than the above, it is determined to be out of place, and the symbol arrangement pattern corresponding to the random value 3 extracted at that time is displayed on the rotating drums 38a to 38c. However, if the pattern coincides with the big hit symbol by chance, “1” is added to the random number 3 and displayed as a missing symbol. The above-mentioned determination of a big hit is a case of a normal probability (hereinafter, referred to as a low probability), and as described later, when the probability is changed (hereinafter, referred to as a high probability), a random decision is made. The value extracted from 1 is “128”
If the value is any one of ".about.137", it is determined to be a big hit. Therefore, the probability of a big hit at the time of low probability is 1/248, whereas the probability of a big hit at the time of high probability is 10/248, which is a ten-fold change. The multiple at the time of high probability may be changed and adjusted to an arbitrary value by the setting switch 64 or the like (another switch may be provided).

As described above, when the start signal S1 is derived, it is determined whether or not the symbols displayed on the rotating drums 38a to 38c are in contact with each other, and the symbols to be displayed when the rotation is stopped are also determined. After termination (in the present embodiment, 0.156 seconds to 0.164 seconds after derivation of start signal S1)
After a lapse of seconds), the fluctuations of the rotating drums 38a to 38c are started with a slight time difference. Then, the left rotating drum 3
In the variable display of 8a, the basic time (5.100 seconds)
During the period, the speed is set to a predetermined fluctuation speed and fluctuates, and when the basic time elapses, the operation is stopped when the fluctuation time for one symbol elapses. Similarly, in the fluctuation display of the right rotating drum 38c, the fluctuation is set at a predetermined fluctuation speed during the same basic time (5.100 seconds) as described above.
It stops when the fluctuation time for six symbols has elapsed.

On the other hand, in the variation display of the center rotating drum 38b, when the stop symbols displayed on the hit lines displayed on the already stopped rotating drums 38a and 38c are not the big hit symbols (when not in the reach state), and when the hit symbols are not reached. At the time (at the time of the reach state), it is variably displayed in a different manner. Therefore, first, the fluctuation display when the vehicle is not in the reach state will be described.
(Second), the speed is set to a predetermined fluctuation speed and fluctuates, and when the basic time elapses, the operation is stopped when the fluctuation time for 11 symbols elapses.

Next, a description will be given of the variable display in the reach state. During the same basic time (5.100 seconds) as described above, the speed is set to a predetermined fluctuation speed and fluctuates. When the basic time elapses, the operation is stopped when the fluctuation time for 49 to 66 symbols elapses. However, the fluctuation speed for the 49-66 symbols is set to a slightly slower fluctuation speed.

As described above, the rotating drums 38a to 38a
The game after c stops the variable display is shown in FIGS.
Is shown in FIG. 11 shows the rotating drums 38a to 38a-3 in a case where there is a starting memory after the opening operation of the variable winning ball apparatus 10 is completed.
FIG. 12 is a time chart showing the fluctuation of 8c, FIG. 12 is a time chart showing the operation of the variable winning ball device 10 when the stop symbol is a big hit, and FIG. 6 is a time chart showing the operation of the variable winning ball device 10. Therefore, referring first to FIG.
To explain the case of disengagement, three rotating drums 38
a to 38c, the rotary drum 38 that stops changing at the end
A fixed time (1.200 seconds) after the fluctuation display of b stops
The value stored in the random 1 is read out at the time when has elapsed, and the values of the random numbers 2 and 3 stored are read out after the lapse of 1.202 seconds, and one value is extracted from the random number 6. Then, after a lapse of 0.156 seconds or 0.164 seconds, first, the left rotating drum 38a starts to fluctuate, and with a slight delay, the middle rotating drum 38b starts to fluctuate. Starts to fluctuate slightly later.

Next, the case of a big hit will be described with reference to FIG. 12. When the fluctuation display of the three rotating drums 38a to 38c is stopped, a fixed time (5.650 seconds) elapses, and then the variable winning ball is won. The device 10 is operated for a relatively long time (29.
(500 seconds) released. However, if the number of winning balls reaches 10 before the predetermined time has elapsed, the winning ball is closed at that point. Then, after this opening is completed, a fixed time (2.000 seconds) is set as the active operation time of the accessory continuous operating device, and the winning ball received by the opening / closing plate 11 after the opening of the variable winning ball device 10 is completed. Is the specific ball detector 13
Is turned on, it is recognized as valid, and a continuation right is generated. Thus, when the continuation right is generated, the variable winning prize ball device 10 is controlled to be opened again after the elapse of the operational useful unit operating time.

By the way, when the symbols displayed when the rotary drums 38a to 38c are stopped are a combination of the big hit symbols, the three types of hit lines shown in FIG. The 24 combinations are associated with random numbers “0 to 23” as shown in FIG. Then, among the jackpot combination modes, “7 (CHANCE)” and “BI”
When the special game state is achieved with the special big hit symbol of “G” (any hit line may be used), the normal symbol variable display 3
5 and the rotating drums 38a to 38c are controlled so as to increase the probability of displaying the specific display result. This will be described with reference to FIGS. FIG. 16 shows that each time an interrupt signal (periodic reset signal) is input (for example,
FIG. 17 is a flowchart showing a main routine executed at 2 msec), FIG. 17 is a flowchart showing a fluctuation counter updating subroutine of probability fluctuation, FIG. 18 is a flowchart showing a fluctuation regulation subroutine of probability fluctuation, FIG.
FIG. 19 is a timing chart illustrating an example of a specific operation of the processing illustrated in FIGS. 17 and 18.

Referring to FIG. 16, first, in step 10 (hereinafter abbreviated as S10), a stack set process for designating an address to be a stack area in the memory area is executed. Then, in S20, whether or not there is a RAM error is determined. R
AM normal) is determined, and if normal, various information data is output from the I / O in S30. Thereafter, in S40, it is determined whether an abnormality has occurred in various switches and there is a warning. If not, a special symbol process process and a normal symbol process process are executed in S50. In the special symbol process processing, the rotation control of the rotating drums 38a to 38c and the opening / closing control of the variable winning ball device 10 in a big hit are performed. In the ordinary symbol process, variable display control of the ordinary symbol variable display 35 and opening / closing control of the electric start winning port 6 at the time of a hit are performed. The above S
After the end of the process of step 50 and when it is determined in step S40 that there is an abnormality, a process of accepting input signals from various switches is performed in step S60.
Creation (update processing), random at S80 2, 3, 5, 6
Is created. When it is determined in step S20 that there is a RAM error, initialization is performed in step S120, and then the processes in steps S70 and S80 described above are executed. As described above, since all random numbers are updated each time the main routine is executed once (every interruption), if the update is performed only within the remaining time of the main routine as in the related art, the remaining time will be reduced. While there is a drawback that the update process is not performed when there is no update process, the update process of the random number is surely performed. Particularly, in the present embodiment, the important random 2 is reliably updated, so that the same large hit symbol arrangement pattern is prevented from being generated continuously.

Next, in S90, the count value of an unillustrated interrupt counter (reset every time 0 to 7 is counted) is determined. When the value of the interrupt counter is "0", a symbol LED (for example, , Numerical display 16 etc.) control and sound data output are executed, and when the value of the interrupt counter is "1 to 7", selection control of the output data table and display control of the decorative LED and lamp are executed in S130. . After that, the process of creating random numbers 2, 3, 5, and 6 (update process) is executed in S110 until the next interrupt signal (periodic reset signal) is input.

The probability variation process in the special symbol process process of S50, that is, the process of updating the probability variation counter of the probability variation will be described with reference to FIG. 17. First, in S200, it is determined whether or not a big hit has occurred. If the hit is not a big hit, the subroutine is terminated. If the hit is a big hit, processing is performed with low probability in S210. Thereafter, it is determined in S230 whether the big hit has seven chances. The value of the fluctuation counter C1 is set to "2" and the subroutine is terminated.
At 40, it is determined whether or not the big hit is BIG. If it is BIG, the value of the probability variation counter C1 is set to "1" at S260, and the subroutine is terminated. If not, the probability variation counter C1 is updated. Ends the subroutine. When the value of the probability variation counter C1 is set to “2” in S250 described above, as shown in FIG.
Since the high-probability state is caused to appear twice, as a result, at least three jackpot gaming states appear at relatively short time intervals. In S260, the probability variation counter C1
Is set to “1”, as shown in FIG. 19B, the high probability state appears once, and as a result, at least two big hitting game states are set in a relatively short time interval. Will appear. In addition, the process of S210 described above
It is not always necessary to do so, and may be omitted. Also, S2
Discrimination processing S that performs the processing after S230 only when the value of the probability variation counter C1 is “0” between 10 and S230.
220 may be inserted. By inserting such a process, the probability improvement period is extended only when the last big hit in the probability improvement period is caused by the probability change symbol.

As described above, a big hit is generated, and the big hit improves the probability (a special big hit display result).
Since the value of the probability variation counter C1 is constantly fluctuated, as long as the probability change symbol is displayed during the probability improvement period, a phenomenon that the probability improvement period is extended indefinitely occurs. In order to eliminate such an unlimited extension, as described in the following flowchart of FIG. 18, a process for regulating the probability fluctuation is performed. Therefore, referring to FIG. 18, it is determined whether or not the big hit has ended in S300. If the big hit has not ended, the subroutine is ended without performing the following processing.
In S310, it is determined whether or not the value of the probability variation counter C1 is "1 or more".
When it is determined to be "0"), the subroutine is terminated without performing the following processing, and when it is determined to be "1 or more", the following processing is executed to maintain a high probability. First, “1” is added to the value of the probability variation control counter C2 in S320, and thereafter, it is determined whether the value of the probability variation control counter C2 is “6 or more” in S330. When it is determined that the value of the probability variation control counter C2 is not "6 or more", it is determined that the value is still within the range of the permitted total, and "1" is subtracted from the value of the probability variation counter C1 in S340. To set a high probability and end the subroutine. On the other hand, the probability fluctuation regulation counter C2
Is determined to be “6 or more”, it is determined that the value exceeds the allowable total range, the value of the probability variation control counter C2 is reset to “0” in S360, and
At 370, the value of the probability variation counter C1 is also reset to "0", and the subroutine ends. When the value of the probability variation counter C1 is set to "0" in S370, the variation operation of the rotating drums 38a to 38c is executed without being changed to a high probability in the subsequent processing and with a low probability. The period will not be extended.

FIG. 19C shows a specific example of the operation shown in FIG. FIG. 19C is a time chart in the case where the big hit occurs continuously at “7 chances” of the probable changing symbol. , The value of the probability variation counter C1 is always set to “2” and the probability improvement period is extended over a long period of time, but the value of the probability variation regulation counter C2 is “5”, After five times, the value of the probability variation counter C1 is reset to "0", so that the processes of S320 to S350 are not executed, and the probability immediately returns to the low probability. For this reason, it is possible to prevent the big hit game state from being established in a short period of time with respect to the subsequent fluctuation results of the rotating drums 38a to 38c. Therefore, there is no great damage to the game hall. FIG. 19 (C) shows a case where the first big hit after the value of the probability variation counter C1 is reset to “0” occurs by chance at “7 chances”. In this case, The probability fluctuation regulation counter C2 starts counting.

In the above-described embodiment, as means for suppressing the probability improvement, the probability fluctuation counter C1 is reset to "0" when the value of the probability fluctuation regulation counter C2 reaches a predetermined cumulative number, and the probability is immediately increased. Although the prohibition of extension of the improvement period has been described, the probability improvement may be suppressed by prohibiting or suppressing the appearance of a probable change symbol that causes the probability improvement. The processing shown in FIGS. 20 and 21 may be performed as such an example. FIG. 20 is a flow chart for reliably preventing the appearance of a probable variable design, and FIG.
It is a flowchart for suppressing the appearance of a probable change symbol. First, FIG. 20 will be described.
In the creation process of the random 2 of 0, an addition process of “1” is performed on the random 2 in S400, and thereafter, in S41.
It is determined whether or not the value of the probability fluctuation regulation counter C2 is “6 or more” at 0. If the value is “6 or more”, it is determined that the cumulative count value exceeds the expected value, and the current value of the random 2 is determined at S420. It is determined whether the value is "18 or more". If the value of random 2 is smaller than "18" (if it is not a probable variable symbol), the subroutine is terminated as it is, and the value of random 2 is "18 or more". (In the case of a probable variable design), S430
To clear the value of random 2 and set it to "0", and terminate the subroutine. Therefore, when the cumulative count value exceeds the expected value, the value of Random 2 is a positively-variable symbol (FIG. 1).
4), it is possible to completely prohibit the occurrence of a jackpot due to a probable variable symbol that causes the probability improvement period to be extended. Meanwhile, S410
When it is determined that the value of the probability fluctuation regulation counter C2 is smaller than "6" in S440, the value of the random 2 is "24 or more" in S440 because the cumulative count value has not yet exceeded the scheduled value.
If it is not “24 or more”, the subroutine is terminated as it is, and the value of random 2 is “24 or more”.
In step S450, the value of random 2 is cleared and set to "0", and the subroutine is terminated. In this way, in the case of this processing, when the value of the probability variation counter C1 remains, the value is not reset to “0”, and the big hit game state by the big hit symbol other than the probable symbol is changed for a short period thereafter. , The complaint of the player can be reduced as compared with the case of the processing in FIG. Note that, instead of the clearing process of S430, S5 described below is used.
Random 2 may be rewritten to a numerical value corresponding to a symbol other than the probable symbol, such as 30.

Next, the operation of suppressing the appearance of the probable symbol will be described with reference to FIG. 21. In S500, it is determined whether or not a big hit has occurred. If not, the subroutine is terminated without executing the following processing. And if it ’s a big hit,
In S510, it is determined whether or not the value of random 2 is any of "18, 20, 21, 23" corresponding to some probable symbols, and if not, the subroutine is executed without executing the following processing. And if any value, S
At 520, it is determined whether or not the value of the probability fluctuation regulation counter C2 is "6 or more". If the value is not "6 or more", the subroutine ends without executing the following processing because the cumulative count value has not yet exceeded the scheduled value. Since it has exceeded, S530
Then, the value of the random 2 "18, 20, 21, 23" is rewritten to "6, 8, 12, 14" which does not correspond to the probable variable symbol, and the subroutine is terminated. Thus, FIG.
The processing shown in FIG. 1 is performed when the cumulative count value exceeds a predetermined value.
Since the appearance probability of the jackpot due to the probable change symbol is lowered (it does not mean that it does not appear completely), extension of the probability improvement period can be suppressed.

In the above-described embodiment, as a game content of the pachinko gaming machine having the variable display devices (rotating drums 38a to 38c), the specific game state is set when the display result of the variable display device is a combination of big hit symbols. The variable winning prize ball device 10 is immediately opened a predetermined number of times (so-called digital pachinko gaming machine), but a right-generating gaming state, which is a kind of specific gaming state, is generated based on the display result of the variable display device. During the continuation of the right generating game state, the ball hits the starting winning opening to open the variable winning ball device for a predetermined period, and such opening is repeated a predetermined number of times on condition that the ball hits the starting winning opening. A pachinko game machine having game contents (so-called right) may be used. Such an embodiment will be briefly described with reference to FIGS. FIG. 22 is a front view of a game board provided with a game device for embodying other game contents, and FIG. 23 shows an internal structure of a special variable winning ball device provided at the center of the game board. FIG. 24 is a perspective view,
It is a front view of the principal part of the game board provided with the special variable winning ball device concerning other structures.

In FIG. 22, the inside of a guide rail 72 provided in a substantially circular shape of a game board 71 is formed as a game area 73, and a special variable prize ball device 90 is arranged substantially in the center of the game area 73. . Special variable winning ball device 90
A plurality of (two) variable indicators 91a and 91b constituting a variable display device, a specific winning area 102, a pair of ball receiving members 104a and 104b constituting a variable winning ball device,
The prize ball guided to the special variable prize ball device 90 in association with the display result of the variable indicators 91a and 91b being a predetermined specific display result is guided to the specific prize area 102 and is not shown. When the specific winning ball detector is turned on, a right-generating game state, which is a kind of the specific game state, is generated. The configuration of the special variable winning ball device 90 will be described later in detail.

The gaming area 73 includes a plurality of winning ports 7.
4, 78, 80, 83a, 83b, 84 (this 84
It is not a winning opening in the correct sense), 87a-87c, windmill lamps 88a, 88b with built-in lamps, windmills (no sign), side lamps (no sign), and out port 8
9 and obstacle nails (no symbol) are provided respectively. First, among the plurality of winning ports, the winning port 74 integrally includes a receiving-type winning port 77 and a winning port having a pair of ball receiving members 75 on one mounting plate above the special variable winning ball device 90. The lower ball receiving member 75 is opened and closed by a solenoid 76, and is prevented from hitting a hit ball by a winning hole 77 located at an upper portion in a closed state. It has become. By the way, when the hit ball passes through the passage opening device 84 described later in detail and the variable display devices 91a and 91b provided in the special variable winning ball device 90 have a predetermined specific display result, the ball receiving member 75 will be described. For a predetermined time (for example, 5.9 seconds), the winning ball received during the opening is guided to the special variable winning ball device 90. However, during the continuation of the right generation gaming state, the opening time of the ball receiving member 75 is extremely short (for example, 0.5 seconds) even if the variable indicators 91a and 91b have a predetermined specific display result. Is controlled so that

The winning opening 80 arranged on the left side of the special variable winning ball apparatus 90 is called a starting winning opening 80, and is provided with a rotating body 81 which is rotated at a predetermined cycle by a motor (not shown). ing. Also, the rotating body 8
1, a ball receiving portion 82 for receiving one hit ball is formed.
The winning ball received by the ball receiving portion 82 is guided to the back surface of the game board 71 and is detected by a starting winning ball detector (not shown). In the start winning port 80 with a rotating body configured as described above, the rotation of the rotating body 81 is controlled at a relatively slow cycle (for example, 2 rpm) in a normal state. This suppresses an unnecessarily high payout rate based on the winning of the hit ball to 80. On the other hand, in the right generation gaming state, the cycle of the rotating body 81 is relatively fast (for example, 6 cycles).
rpm), the ball receiving portion 8 of the rotating body 81 is controlled.
When the winning ball accepted by the player 2 is guided to the back of the game board 1 and the starting winning ball detector is turned on, the ball receiving member 1 constituting the variable winning ball device provided in the special variable winning ball device 90 is provided.
04a and 104b are opened until a predetermined time (for example, 9.5 seconds) elapses or until a predetermined number (for example, 10) of winning balls is generated until the predetermined time elapses. The rotation cycle of the rotating body 81 is determined by the ball receiving member 104.
The opening time is set substantially the same as the opening time of the a and 104b.

Here, the game contents in the right generation game state will be briefly described.
When the display result of 1a, 91b becomes a predetermined display result and a hit ball is guided to the specific winning area 102 and the specific winning ball detector is turned on, a right generating game state is set. Then, when the hit ball wins the starting winning opening 80 and the starting winning ball detector is turned on while the right generation gaming state is continued, the ball receiving members 104a and 104b perform the above-described opening operation. Then, such an opening operation is repeated every time a hit ball wins the starting winning opening 80 as long as the right generating game state continues. However, the continuation of the right generation game state is performed again by changing the variable indicators 91a and 91 during the right generation game state.
The display result of b becomes a predetermined display result, and the hit ball is guided to the specific winning area 102, and the specific winning ball detector is turned on.
The process ends when a predetermined number (for example, 16) of hit balls is won in the starting winning port 80.

In the winning in the starting winning opening 80, up to "predetermined number-1" winning balls are stored, and the ball receiving members 104a and 104b are opened based on the stored value. When the rights accrual status has expired and
After the opening operation at the time when the number reaches the predetermined number (even if the opening and closing operation is 16 times or less), the subsequent opening operation is not performed. Therefore, it is desirable that the winning of the ball into the starting winning opening 80 and the opening operation of the ball receiving members 104a and 104b be performed alternately. However, in the present embodiment, as described above, the rotation period of the rotating body 81 is changed. As a result, the winning in the starting winning opening 80 is made only at intervals substantially equal to the opening time of the ball receiving members 104a and 104b, so that the winning in the starting winning opening 80 and the ball receiving member 104 are achieved.
There is a high possibility that the opening operations a and 104b are alternately performed. Further, in the present embodiment, when the right generating game state is set, the opening time of the ball receiving member 75 of the variable prize ball device 74 is shortened, so that it is difficult for the specific prize area 102 to win again. ing.

On the other hand, the prize port 78 arranged on the right side of the special variable prize ball device 90 is a mere prize port itself, but is provided with an operation number display LED 79 so as to face the front thereof. In this embodiment, the number-of-actuations display LED 79 displays the rights-generation gaming state multiple times (three times) consecutively at short intervals, and thus displays the plurality of times in a countdown manner. Things. The winning openings 83a and 83b provided diagonally below the left and right sides of the special variable winning ball device 90 are sleeve winning openings 83.
a, 83b, and a sleeve lamp is built therein. Further, the prize holes 87a to 87c arranged in the horizontal direction below the game area 73 constitute normal prize holes 87a to 87c for simply prize hitting balls. However, the number of prize balls to be paid out based on the winning of the ball to the left and right winning openings 87b and 87c is the number of prize balls to be paid out based on the winning to the other winning opening (for example, 1).
5) (for example, 7).

The winning opening 84 disposed on the right side of the winning opening 83a is called a passing opening device 84. The passing opening switch 85 is built in a hollow square passing frame projecting from the mounting board. I have. Thus, when the hit ball passes through the pass frame and turns on the pass switch 85, the change of the variable indicators 91a and 91b is started, and when a predetermined time (for example, 5.5 seconds or more) elapses. , To derive the display result. In addition, the passing opening device 84 is to discharge the passing ball to the game area 73 again, but it may be formed as a winning opening. In addition, the passage opening device 8
As described above, the variable display 91a, 91b is changed as described above to indirectly open the ball receiving member 75 of the variable prize ball device 74. It is greatly involved in whether or not it is guided to the region 102. Thus, a movable member 86 is provided which protrudes and retracts from the rear surface of the mounting board above the passage frame by the operation of the solenoid. In, the movable member 86 is projected forward of the mounting board. By configuring the pass-through device 84 in this manner, it is possible to configure a right generation gaming state disappearance prevention control unit. However, both the right generation game state elimination control means by the control of the ball receiving member 75 and the right generation game state elimination control means by the passage opening device 84 may be used at the same time, but either one may be used. That is enough.

Next, the configuration of the special variable winning ball device 90 arranged at the center of the game area 73 will be described with reference to FIGS. 22 and 23.
This will be described with reference to FIG. The special variable winning ball device 90 has a mounting board mounted on the surface of the gaming board 71, and the variable indicators 91a, 91b and the ball receiving members 104a, 104b constituting the variable winning ball device are integrated on the mounting board. Is formed. The variable displays 91a and 91b are constituted by dot matrix LEDs, and the left
1a sequentially displays 10 kinds of numbers from 0 to 9 in a variably manner, and the variable display 91b on the right side sequentially displays numbers from 0 to 9 and 11 kinds of numbers of English letters of F in a variably manner. I have. When the combination of the symbols at the time of stop (display result) becomes the combination of the "same number of the same number", it is determined that the specific display result is displayed, and the ball receiving member 75 is held for a predetermined time as described above. Open. Further, the probability that the specific display result is displayed is controlled so as to change. Specifically, in the normal game state, 1/33
The specific display result is derived with a low probability of 0, and the occurrence of the right generation gaming state is “3.3” or “5.5” in the specific display result.
And 1/3 when it is caused by the "7/7"
3 is changed to the high probability, and is changed to the low probability by the establishment of the right generation game state a predetermined number of times (for example, two times) after the high probability. Therefore, "3.3""5.5"
And the zigzag pattern of “7.7” constitutes a probable change pattern. The determination as to whether or not it is a hit, and the determination of the symbol displayed on the variable indicators 91a and 91b at the time of stoppage, are made by selecting one value from a random number predetermined at the time of operation of the passage switch 85 or at the start of the change. This is done by extracting Further, the values of the high probability and the low probability described above may be changed by a setting switch. For example, the low probability is 1/3
In the range of 30 to 1/390, the high probability corresponds to 1 /
Each of a plurality of levels (for example, 3
The setting may be changed in step).

A winning space is formed below the variable indicators 91a and 91b. In this prize space, a prize ball received by the ball receiving member 75 of the variable prize ball device 74 is guided, and a rotating body 97 rotated by a motor rotates the normal prize area 96 or the specific prize area 10.
2 can be sorted. Then
The configuration of the winning space will be described with reference to FIG. 23. The winning ball received by the ball receiving member 75 flows down the U-shaped ball passage 92 and is formed at the center of the ball rolling plate 95. To the rotating body 97 from the ball outlet 93. The ball rolling plate 95 is formed in the winning space so as to incline downward from the front and rear toward a normal winning area 96 formed forward. By the way, ball passage 92
Is for guiding the winning prize balls flowing down in a line, and when the first prize ball P1 reaches the rotating body 97 and stops, the fourth prize ball from the first prize ball P1. P
The ball outlets 94a, 94b (9
4a is formed, and is guided to the normal winning area 96 through both sides of the ball rolling plate 95 as shown by the arrow in FIG. Accordingly, three winning balls P1 to P3 are stored in the ball passage 92 in a standby state, and the further winning balls are guided to the normal winning area 96 without being stored.

A rotating body 97 faces the ball outlet 93 formed at the lower end of the ball passage 92 described above. The rotating body 97 is rotated in a horizontal direction by being surrounded by an enclosing frame 98, and has a receiving recess 99 on its outer periphery for receiving one winning ball.
a, 99b and 100 are formed in plurality (three). Of the receiving recesses, two receiving recesses 99a and 99b are:
It penetrates in the vertical direction, and in one receiving recess 100,
A bottom plate is formed. Therefore, receiving recesses 99a, 9
The winning prize ball received in the 9b is a normal prize opening 10 formed in the bottom plate on which the rotating body 97 is placed in the process of moving.
1 and is guided to the normal winning area 96. On the other hand, the winning ball received in the receiving recess 100 is guided to the specific winning region 102 formed in the front center of the ball rolling plate 95 without dropping from the normal winning opening 101.

The rotating body 97 is driven to rotate by a motor (not shown) as described above. The motor is constantly rotating at a constant speed (for example, 10 rpm), and the ball receiving member 75 is opened. The rotation is temporarily stopped at a predetermined position for a period before and after the rotation, and then the rotation is continued. In this case, when three prize balls are stored in the ball passage 92, one of the three prize balls is surely received by the receiving recess 100 and guided to the specific prize area 102. Cause a right generation game state.
In order to stop the rotating body 97 at a predetermined position, a stop position detector (not shown) is provided.

The structure of the winning space is as described above.
A winning area 103 is provided below the mounting board below the winning space.
Are formed, and a pair of ball receiving members 104a and 104b are provided so as to be openable and closable in order to control winning of the hit ball into the winning area 103. In the present embodiment, the ball receiving members 104a and 104b constituting the variable winning prize ball device are shown as being provided integrally with the special variable winning prize ball device 90. It may be arranged. Similarly, the variable indicators 91a and 91b may be arranged separately from the special variable winning ball device 90.

In the pachinko gaming machine having the above-mentioned game contents, the probability improvement period is extended as long as the display results of the variable indicators 91a and 91b display a probable change symbol. Since it occurs continuously, it causes a great deal of damage to the game hall. However, in order to prevent such disadvantages, the variable display 91a,
In the control of 91b, FIG.
By performing the same processing as in 1, it is possible to prevent continuous occurrence of the right-generating gaming state at short time intervals, and to prevent a great deal of damage to the game hall.

In the above embodiment, the variable display 91
a, 91b displays the specific display result, but the specific prize area 1
The embodiment in which the right-playing state is not established unless a ball is hit in 02 (such a variable display device is usually referred to as a symbol variable display device) has been described, but the display result of the variable display device indicates a specific display result. A variable display device (which is sometimes referred to as a special symbol variable display device) that always makes the right-generating game state may be provided. An embodiment provided with such a special symbol variable display device is shown in FIG.

The special variable prize ball device 110 arranged at the center of the game board has a ball entrance 111 at the top thereof, and the ball hit from the ball entrance 111 receives a symbol switch 112 provided below. Guided to stop. Symbol switch 1
When 12 is turned on by a winning ball, the variable display device 113 having three variable displays starts to change and stops after a predetermined time. Then, when the display result displayed at the time of the stop becomes a predetermined specific display result (for example, the same number of doubled eyes), the rotating body 114 starts rotating clockwise and is formed on the rotating body 114. Receiving recess 115
Then, the winning ball stopped at the symbol switch 112 is accepted, guided to the specific winning area 116, and a specific winning ball detector (not shown) is turned on to enter the right-generating game state. On the other hand, when the display result of the variable display device 113 becomes a display result other than the specific display result, the rotator 114 rotates counterclockwise to guide the winning ball received in the receiving recess 115 to the normal winning area 117, and Is processed as a winning ball. In the right-generating game state, each time a hit ball wins the start winning port 120 and the start winning ball detector 121 is turned on, the ball receiving members 118a and 118b are opened for a predetermined period and the winning area 11 is opened.
9 is repeated. In this manner, in this embodiment, when the variable display device 113 displays the specific display result, the game is always in the right generation game state.

By the way, the manner in which the symbol displayed when the variable display device 113 according to the above-described embodiment is stopped is the result of the specific display is the same number of doubles.
There are 10 ways, of which "3.3.3""5.5"
・ 5 ”and“ 7.7.7 ”special display result (probable change design)
In the right-playing state, the variable display device 1
13 is controlled so that the probability of displaying the specific display result is improved. Therefore, as long as the display result of the variable display device 113 displays a probable change symbol, the probability improvement period is extended, so that the right generation game state is continuously generated at short time intervals, which greatly damages the game hall. In other words, in order to prevent such a disadvantage, the variable display device 113 is used.
In the above control, if the same processing as that of FIGS. 18, 20, and 21 is performed, continuous occurrence of the right generation game state at short time intervals is prevented, and no great damage is given to the game hall. You can do so.

Although a plurality of embodiments have been described above, in any of the embodiments, the variable display devices 38a to 38c, 91a, 91b, 113 during the probability improvement period.
Is displayed, the probability variation counter that regulates the probability improvement period is displayed.
Since the value of 1 is updated, the probability improvement period is extended as a result, and it is possible to give the player a sense of satisfaction. On the other hand, the probability fluctuation regulation for counting the cumulative value of the number of times of improvement is provided. When the counter C2 reaches a predetermined value, the probability variation counter C1 is reset, and the appearance of a probable variable symbol is prohibited or suppressed, so that a further extension of the probability improvement period is suppressed, and a great deal of damage to the game hall is caused. Never give.

In the above-described control operation, the updating of the value of the probability variation counter C1 to the initial setting value has been described as the mode of updating. However, the remaining value of the probability variation counter C1 may be the initial setting value or an arbitrary value. An addition update setting mode for adding a numerical value (for example, 1) may be used. In addition, the value of the probability variation counter C1 and the value of the probability variation regulation counter C2 are displayed on a dedicated display or other displays (for example, the numerical display 16, the decorative design 34, or the variable display for a normal design). The display may be shared by the device 35 etc.). In the case of the dual-use display, the display area is divided into the original display information and C1,
The value of C2 may be displayed at the same time, or may be displayed alternately at predetermined time intervals. In the above-described embodiment, the predetermined condition is satisfied when the combination of the jackpot symbols is established among the combinations of the jackpot symbols. For example, a random number dedicated to the jackpot to be extracted when the jackpot occurs is set in advance. When a predetermined numerical value is reached, or during a predetermined period (for example, every time a predetermined time elapses from the start of business, when there is a predetermined number of starts after the end of a big hit, when there is a predetermined number of reach after the end of a big hit) Later, when the big hitting game state is reached, it may be the time when the phenomenon related to the game is established. Further, in the above-described embodiment, a predetermined symbol is set as a special big hit symbol. However, when a normal big hit symbol is aligned on a specially determined hit line, a normal big hit symbol is displayed on a plurality of hit lines. The display result of the variable display means (variable display or pseudo-video game) which fluctuates after the big hit and when the special big hit symbols are aligned on the specially determined hit line becomes the predetermined display result. In this case, a special display result may be used. Further, in the above-described embodiment, a case where the probability of the ordinary symbol and the special symbol are simultaneously changed by the establishment of the same condition has been described. However, the probability may be changed under different conditions or only one of them.

Further, in the above-described embodiment, the mechanical variable display device including the rotating drums 38a to 38c has been described as the variable display device. However, the variable display device is electrically variable (for example, LCD, CRT, dot matrix LED). )
Other mechanical variable display devices (for example, a belt type or a rotating disk type) may be used. Further, although a pachinko gaming machine has been described as a ball-and-ball gaming machine, a so-called arrangement-type pachinko gaming machine may be used. In the above-described embodiment, the electric start winning port 6 corresponding to the normal symbol variable display device has the function related to the occurrence of the specific game state.
When the variable winning prize ball device corresponding to the normal symbol variable display device is assumed to be completely unrelated to the occurrence of the specific game state, the same control as in the present embodiment is performed, so that the variable Since the winning ball device is frequently opened, more balls can be obtained, and the game content can attract the interest of the player in a meaning different from the present embodiment.

[0061]

As is apparent from the above description, in the first aspect of the present invention, the specific game state is set based on the fact that the display result of the variable display device is a predetermined specific display result. In a ball game machine that gives a predetermined game value to a player, the probability that the display result of the variable display device displays the specific display result based on satisfaction of a predetermined condition is determined by a predetermined number of times thereafter. Probability improvement means for improving until a specific game state occurs, and a probability improvement number update for updating the value of the predetermined number of times when the predetermined condition is satisfied again during the probability improvement period improved by the probability improvement means. Means, and a display for displaying the value of the predetermined number of times. With this configuration, a value (a predetermined number of times) that regulates the probability improvement period
In the ball game machine that gives the player a sense of satisfaction by updating the number of times, the number of times the probability is improved can be displayed on the display.
