Abstract

PURPOSE: To provide a third type Pachinko (Japanese pinball game) machine capable of improving the will of play by prolonging the holding of balls under high probability and improving the feeling of expectation on right generation. CONSTITUTION: Two kinds of terms to open a normal motor-driven accessory 32 are set as long time, for which probability for a prize winning game ball to pass through a specified area is set high corresponding to the kind of a hit, and as short time for which the probability for the prize winning game ball to pass through the specified area is set low, and the short-time hit is set to be frequently generated so as to be ten times rather than the long-term hit. In the state of high probability, the short-time hit is frequently generated and the prize winning ball at the normal motor-driven accessory 32 is dispensed. Therefore, even if the right of a special game is not generated, the held balls are not decreased so much.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine equipped with a symbol display device having a plurality of symbol display parts, and more particularly to a third-class pachinko machine in which the probability of a big hit varies.

[0002]

2. Description of the Related Art Various pachinko machines have been proposed which produce a profitable operation for a player when a stop symbol of a symbol display device which variably displays various predetermined symbols is a hit symbol. As this profitable operation, the specific winning opening is opened by the winning symbol, the right is generated by the gaming ball winning the specific winning opening passing through the specific area, and the winning is given to the predetermined starting opening while the right is generated. Open the prize hole by
There is a so-called type 3 pachinko machine. This third
Even on seed pachinko machines, after winning, the probability of changing to a predetermined symbol combination on the symbol display device is changed with a high probability to easily generate the next hit and the probability variation method that enhances the enjoyment of the game is often adopted. Has been done.

[0003]

The player's greatest interest in the game is whether or not it is a hit, and it is generally preferred that the symbol display device has a large number of symbol fluctuations, but on the other hand, the starting opening is used. If there is a lot of variation in the pattern, the number of balls will be increased and it will be difficult to adjust the prize balls. For this reason, in order to generate more symbol variations and to take a balun of the ball out, a method of causing symbol variation by an operating gate that does not pay out game balls is often used especially in the third class pachinko machine. . It is a method to start the fluctuation of the symbol by the passage of the game ball of this operating gate, and in the 3rd type pachinko machine that changes the probability of occurrence of a hit, when it hits with a predetermined symbol, a considerable number of prize balls are awarded. While paying out, the probability of becoming a predetermined symbol combination is changed to a high probability (for example, 10 times), and the player is provided with a state in which a hit is likely to occur. However, in this type of pachinko machine, even if the game ball passes through the actuation gate and the fluctuation of the symbol starts, there is no payout of the prize ball, so the player will be able to hit the above by the time the next hit occurs. Sometimes I hit all the game balls I got in. Such a situation is likely to occur when the nail adjustment is performed so that the winning in the other winning openings hardly occurs. In addition, in this high probability state, the situation of reducing the game balls acquired until the next hit occurs is less than the method by the operating gate, but the method of causing the symbol variation by the starting opening is the third It also occurred in seed pachinko machines. For this reason, even if the state transitions to the high probability state, not only the benefits cannot be fully utilized but also the player's willingness to play may be impaired.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to improve ball retention under a high probability and to increase the expectation for the right to be generated, thereby motivating the player to play the game. An object is to provide a type 3 pachinko machine that can be improved.

[0005]

In order to achieve the above object, in the pachinko machine of the present invention, in the aspect described in claim 1, a symbol display device for variably displaying various predetermined symbols. In the pachinko machine that opens the specific winning opening when the stop symbol of the winning symbol is a winning symbol, and the gaming ball that has won the specific winning symbol passes through the specific region to generate a special game right to the player, depending on the winning symbol. It is characterized in that a plurality of opening times of specific winning openings are defined.

[0006] Further, in the aspect described in claim 2,
By passing through a specific gate of the game ball or winning the starting opening, it consists of a plurality of symbol display parts that variably display various symbols determined in advance, and a symbol display device that hits a specific state of the symbol, Depending on the winning symbol of the symbol display device, a specific winning hole control means for opening a specific winning port for a long time or a short time, and a probability of hitting the symbol of the symbol displaying device in a predetermined game state The probability variation means for switching between a high state and a low state according to the above, and a right generation means for generating a right of a special game to a player when a game ball winning the specific winning opening passes through a specific area. , The long time is set so that the probability that the game ball won the specific winning opening will pass through the specific area is high, and the short time is the probability that the game ball winning the specific winning opening will pass through the specific area. Set low Occurrence probability per generating the opening of the short time, characterized in that it is set higher than the probability per generating a long open.

[0007]

According to the present invention having the above-mentioned structure,
In the third-class pachinko machine of the aspect, since the opening time of the specific winning opening is determined by the winning symbol, it is possible to frequently open the specific winning opening by providing the opening for a short time. You can improve your ball life.

In the conventional type 3 pachinko machine in which the variation of the symbol starts due to the passage of the game ball to the operation gate or the winning of the starting opening, and the probability of winning the symbol varies, the probability of occurrence of the collision becomes high. Even after the transition, and even when the right to play the special game is expected, the number of balls held may be reduced before the right to play the special game. On the other hand, claim 2
In this mode, even if there is no chance of causing a long-time opening set so that the probability that the game ball that has won the specific winning opening will pass through the specific area is high, in the high probability state, this long time The probability of opening for a short time, which is set higher than the probability of causing the opening of the game (the probability that a game ball that has won a specific winning opening will pass through a specific area is set low) frequently occurs. , Since the prize balls are paid out because there is a prize in a specific prize hole, it is not necessary to reduce the number of balls held until the next special game right occurs.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a game area of a pachinko machine according to an embodiment of the present invention. On the front surface of the game board 20, a guide rail 48 for guiding a game ball, which is launched from a game ball launching device (not shown) operated by a launch handle (not shown), to an upper portion of the game board 20, is provided.

On the other hand, on the relay board 90, the above-mentioned speaker 91 and the game ball discharging device 92 for paying out the game balls to the winning balls (in this pachinko machine, the special winning opening 24 and the ordinary electric accessory 32). 13 game balls are paid out for winning a prize, and 7 payouts are made for winning for other winning holes), and a game ball launching device is further connected. Various devices such as the switch are further connected, but illustration and description thereof are omitted here for convenience.

Next, with reference to FIG. 1, the outline of the game by the pachinko machine will be described. Here, first, the outline of the game using the ordinary electric accessory 32 will be described. When the game ball passes through the normal symbol operation gate 21, the normal symbol display device 34
The fluctuation of the pattern starts. That is, the normal symbol display device 34
Is mainly red in the left normal symbol display portion 34A (hereinafter referred to as the display portion 34A) and the right ordinary symbol display portion 34C (hereinafter referred to as the display portion 34C) as shown in FIG. 14 (A) (FIG. Please note that the middle red is displayed in black) 0
11 kinds of symbols consisting of 10 kinds of numbers of 9 to 9 and whales are variably displayed, while red is displayed on the central ordinary pattern display portion 34B (hereinafter referred to as display portion 34B) as shown in FIG. 14 (B). Consists of 10 types of numbers from 0 to 9 and greens (note that the green color is shown in white in the figure) and 10 types of numbers from 0 to 9 and a whale picture 21 types of symbols are variably displayed, and when the preset time elapses, the variation of the symbols is stopped in the order of the display unit 34A, the display unit 34B, and the display unit 34C. Then, the winning symbol shown in FIG. 14C (hereinafter, referred to as a short-time symbol, the symbol * in the figure)
(Indicates that any pattern may be used), the normal electric accessory 32 is opened for about 0.85 seconds, and FIG.
In the case of the hit design shown in (D) (hereinafter referred to as the long-term design), the normal electric accessory 32 is opened for about 5.8 seconds, which provides a state in which the game balls can be easily won. If three or more game balls are won during the opening of the ordinary electric auditors product 32, a right state occurs and the special winning opening 24 can be opened as described later. Object 32 0.85
While it is difficult to win 3 prizes when the seconds are released, 5.
With 8 seconds open, you can win 3 or more game balls with a very high probability. In addition, the game ball is a normal symbol operation gate 21
Even after passing, the first four are stored (also displayed on the gate passage memory number display device 37 described above), and no more values are retained. In the state where this passage is stored, after the display fluctuation of the normal symbol display device 34 is stopped, the display fluctuation is started again.

As described above, when three or more game balls are won while the normal electric accessory 32 is open, a right state occurs (hereinafter, this is referred to as operation of a special device). At this time, when the game ball wins the third type starting opening 25, that is, fits into the recess 22a of the rotary chucker 22, the rotary chucker 22
Is conveyed downward by the rotation of the rotary chucker passage opening 2
Pass 3. As a result, the special winning opening 24 is opened for about 9.8 seconds, and a state in which the game balls are very easy to win is provided. Even if the 9.8 seconds have elapsed or the opening time has expired, approximately 10 game balls are won and the special winning opening 24 is closed. After closing the special winning opening 24, the third winning opening 25 is won again to open the special winning opening 24. In addition, the number of times of opening the special winning opening 24 is up to 16, and thereafter, the right state disappears.

By stopping the operation of the special actuation device, the pachinko machine of this embodiment switches between the low probability and the high probability that the above-mentioned ordinary symbol hits. That is, the probability is changed once every time the operation of the special device is ended odd times after the power is turned on. In the low probability state, the probability of winning is set to 1/20, and in the high probability state, it is set to be 1/2 of 10 times that in the low probability state.

Here, the operation of the control board 50 for performing a game by the above-mentioned pachinko machine will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. Here, a main processing procedure of the control board 50 will be described with reference to a flowchart of FIG. 7 showing a main routine. First, C
The PU circuit 57 determines whether the power is turned on (S10
2) Step 1 for the first loop immediately after the power is turned on
The procedure proceeds to 04, the initial setting is performed, and the main routine is ended. If it is determined that the power is not turned on (S10
2 is No), a signal about a winning ball or the like from the winning output unit 88 (see FIG. 6) is input, an input process is performed to prepare it for use in another phase (S106), and the output edited output data is output. Output port 51 and input / output port 52
Output processing for outputting to (see FIG. 6) is performed (S108).

After that, a gate passing process, which is a process for the game ball that has passed through the normal symbol operating gate 21 (see FIG. 1), is performed (S110), and the symbol of the normal symbol display device 34 is changed along with the gate passing process. At the same time, a symbol variation process for determining whether or not to win is performed (S112). Then, the ordinary electric auditors product processing for activating the ordinary electric auditors product 32 is performed according to the hit (S114), and the ordinary electric auditors product 3
2 When there is a passage of a game ball in the special device operating area during opening,
A right generation process for opening and closing the special winning opening 24 is performed (S11).
6). After that, the voice output process for outputting the voice through the sound generator 58 is advanced (S118), and the one cycle main routine process is completed. The main routine is repeated every time a reset signal from the clock 56 is applied to the CPU circuit 57.

The processing from step 110 to step 116 described above will be described in detail with reference to the subroutines shown in FIGS. First, the gate passage processing in step 110 will be described with reference to the subroutine shown in FIG. First, the CPU circuit 57 determines whether or not the game ball has passed the normal symbol actuation gate 21 based on the signal from the prize output unit 88 (S122), and if the game ball has not passed (S122). No), the gate passage subroutine is ended. On the other hand, when the game ball has passed (Yes in S122), it is determined whether the variable U is less than 4 (S124). Here, the variable U indicates the number of game balls that have normally passed through the symbol actuation gate 21, and in this embodiment, as described above, the number exceeding 4 is not held. Therefore, when the variable U is 4, (S1
24 is No), the subroutine is completed. On the other hand, when the variable U is less than 4 (Yes in S124), the variable U is set to 1
Addition is performed (S126), and the process ends.

Next, the symbol variation process in step 112 of FIG. 7 will be described with reference to the subroutines shown in FIGS. 9, 10 and 11. Here, when the game ball does not pass through the normal symbol operation gate 21, that is, the process when the variable U is 0 will be described. In the flowchart of FIG. 9, first, the CPU circuit 57 determines whether or not the symbol of the normal symbol display device 34 is changing (S202), but since the symbol is not changing here (No in S202),
It is determined whether or not the variable U is 1 or more (S204), but since the variable U is 0 (S204: No), the subroutine process is ended.

Next, the process after the game ball passes through the normal symbol actuation gate 21 and the variable U becomes 1 will be described. In the flowchart of FIG. 9, first, the CPU
The circuit 57 normally determines whether the symbol of the symbol display device 34 is changing (S202), but here, since the symbol is not changing (S202 is No), it is determined whether the variable U is 1 or more (S204). ), Since the variable U is 1 here (Yes in S204), 1 is subtracted from this variable U (S206). Then, the variation of the symbol of the normal symbol display device 34 is started (S208). Next, CPU circuit 5
7 determines whether the variable m indicating the number of times the special device has been operated, that is, the number of times the right state has occurred is an odd number (S21).
0). Here, the description will be continued assuming that m is an even number (low probability state) (No in S210).

In step 212, a random hit value for generating a hit with a low probability is set. That is, FIG.
By setting "7" out of the 20 frames from 0 to 19 shown in (A) as a hit, the hit is adjusted with a probability of 1/20. Then, the hit is determined by the set random number value (S216). Here, when a hit occurs (Yes in S216),
A winning symbol is selected (S218). That is, FIG.
One of the random numbers of 231 frames from 0 to 230 shown in (B) is selected. Here, the description will be continued assuming that the random number “0” is selected. Next, it is determined whether the winning symbol is a long-term symbol that normally opens the electric accessory 32 for a long period of time, or a short-term symbol that opens only for a short period of time (S220). Here, as described above, the random number "0"
Is selected, and the red 000 which is the design corresponding to this is selected.
Is equivalent to the design for a long time described above with reference to FIG. 14D, so this step 220 becomes Yes,
The long time flag is set to "1" (S222). On the other hand,
For example, when the random number “1” is selected in step 218, the red 011 which is a symbol corresponding to this is displayed in FIG.
Since it corresponds to the symbol per short time described with reference to (C), this step 220 becomes No and the long time flag is not set. After that, the hit flag is set to "1" (S224).

Next, the CPU circuit 57 selects a reach random number for differentiating the stop operation when the symbols of the normal symbol display device 34 stop changing (S226). Here, either 1 or 2 is selected as the random number value (note that, in the actual operation, more stop operations are set, but here, for convenience of explanation, only two types are described. Continue). Then, the CPU circuit 57 sets this selection value in the reach variable r (S228). Here, description will be continued assuming that the random number value 1 is selected in step 226 and that “1” is set as the reach variable r in step 228. Then, the variable stop time corresponding to this reach variable 1 is set in the symbol timer and started (S230), and the symbol variation process subroutine is ended.

Here, in the judgment of whether or not the hit in step 216 described above, if there is a failure (S216
No) shifts to the B section. The processing in part B will be described with reference to FIG. First, the CPU circuit 57
Selects an outlier symbol on the display unit 34A of the normal symbol display device 34 (S250). That is, as shown in FIG. 15C, one of 11 random numbers from 0 to 10 is selected. Here, the description will be continued assuming that the random number “7” (the pattern of red numeral 7) is selected. Next, the symbols on the display unit 34B are selected (S252). That is, as shown in FIG. 15D, one of the random numbers of 21 frames from 0 to 20 is selected. Here, random number "7" (red number 7 pattern)
The explanation is continued assuming that is selected. Then, the CPU circuit 57 determines whether the symbol on the display unit 34A and the symbol on the display unit 34B are the same. Here, as described above, the symbols on the display unit 34A and the symbols on the display unit 34B are the same (Yes in 254), and therefore, the process proceeds to the process of performing the detach reach symbol display. Here, first, the display unit 3
The 4C symbol is selected (S256). That is, FIG.
The symbols are selected in the same manner as for the display unit 34A described above with reference to (C). After that, the selected symbols are shown in FIG. 14 (C),
It is determined whether or not the hit design shown in (D) is applicable (S
258). Here, if the hit pattern is applicable (S2
58 is Yes), the process returns to Step 256 and the display unit 34 is displayed again.
The design of C is selected. On the other hand, when it is not the winning symbol (No in S258), the symbol on the display unit 34B and the display unit 3 are displayed.
It is determined whether or not there is only one difference from the design of 4C (S2
62). Here, as described above, the random number value "7" (red numeral 7) is added to the symbol on the display unit 34A and the display unit 34A.
Since the random number value "7" (red numeral 7) is selected for the symbol B, if the random number value "6" (red numeral 6) is selected for the symbol on the display unit 34C, the step 260 Is Y
The result is es, and outlying reach random numbers for differentiating the stop operation of the symbols are selected (S262). Here, either 3 or 4 is selected as the random number value (note that although more stop operations are set in the actual operation, there are only two types here for convenience of explanation). Continued explanation as things). Then, the CPU circuit 57 sets the value of the selected value 3 or 4 as the reach variable r (S264). After that, the variation stop time of the symbol corresponding to the reach variable 3 or 4 is set in the symbol timer (S266), and the symbol variation process subroutine is ended.

In the judgment of step 260, for example, when the random number "2" (red number 2) is selected as the symbol of the display portion 34C, the step 260 is N
When it becomes o, the process proceeds to step 268 to select the outlying reach random number (S268). Here, the random number is 5
Or 6 will be selected. The value is set as the reach variable r (S270), the variation stop time of the symbol corresponding to this reach variable 5 or 6 is set in the symbol timer (S272), and the symbol variation process subroutine is ended.

Furthermore, in the judgment of the above step 254, when the design of the display unit 34A and the design of the display unit 34B are different (No in 254), the process shifts to the normal process for displaying the misalignment. Here, first, the display unit 3
The 4C symbol is selected (S274). That is, FIG.
The symbols are selected in the same manner as for the display unit 34A described above with reference to (C). Then, it is determined whether or not the selected symbol corresponds to the hit symbol shown in FIG. 14 (C) (S27).
5). Here, when the hit symbol is applied (S275
Yes), the process returns to step 274 and the symbols on the display unit 34C are selected again. On the other hand, if it is not a winning symbol (No in S275), the reach variable r is set to 0 (S2
76), the symbol timer is set at the set time of the normal stop (S278), and this subroutine is finished.

Here, in step 208 shown in FIG. 9, the process after the symbol variation of the normal symbol display device 34 is started will be described. When the symbol variation processing subroutine shown in FIG. 9 is started, the determination at step 202 whether the symbol variation is in progress becomes Yes, and the process proceeds to the C section. The processing of the C section will be described with reference to FIG. Here, first
Reach variable r as being the stopping operation of the normal outlier pattern
A case in which 0 is set in will be described. Until the stop time of the normal outlier symbol elapses, the determination in step 302 of whether the symbol timer time is up becomes No, the processing of the C section is ended, and the variation of the symbol is continued. On the other hand, when the stop time of this symbol is reached, the symbol timer times out (Yes in step 302), and the CPU circuit 57 determines whether the reach variable r is 0 (S304), but here the determination in step 304 is Yes. Then, the process proceeds to step 306, and the display portions 34A, 34B, and 34C of the normal symbol display device 34 are sequentially stopped by the normal off symbol stop operation, and the process ends.

Next, the symbol stop processing in the case where the hit occurs as described above and 1 is set to the reach variable r in step 228 shown in FIG. 9 will be described with reference to FIG. 11 again. When the symbol timer set according to the value of 1 of the reach variable r times up (Yes in S302), it is judged whether the reach variable r is 0 (S304) and then the judgment of whether the reach variable r is 1 (S308). Is Yes, the process proceeds to step 310, and the symbols are stopped by normal reach. That is, red “0” and “0” (see FIG. 15B) corresponding to the random number “0” selected in step 218 (FIG. 9) described above are displayed on the respective display units 34A and 34B, and are sequentially displayed. After the stop, the speed of the symbol fluctuation of the display unit 34C is set to a low speed and then the red "0" is displayed to stop the fluctuation. In addition,
When 2 is set to the reach variable r in step 228 (FIG. 9), the symbol variation of the display unit 34C is stopped in a manner different from this.

Next, with reference to FIG. 11, a description will be given of the symbol stopping process in the case where no hit occurs, but in the case of the reach reach in the selection of the off symbol. here,
The description will be continued assuming that the reach variable r is set to 3 in step 264 shown in FIG. 3 for this reach variable r
When the symbol timer set according to the value of is up (Yes in S302), next, steps 304 and 30
8 and 312, it is judged whether the reach variable r is 3 (S31
6) is Yes, the process proceeds to step 318, and the symbol stop operation is performed by the reach. That is, each display unit 34
A, 34B, step 250 shown in FIG.
After the red numbers "7" and "7" corresponding to the random number "7" selected in 252 are displayed and sequentially stopped, the display unit 34
The speed of the symbol fluctuation of C is slowed down, and once stopped, the engine is restarted and then the red "6" is displayed to stop the fluctuation. In addition, when the reach variable r is set to 4 in step 262, or when the reach variable r is set to 5 or 6 in step 270, the symbols of the display units 34A, 34B, and 34C are displayed in a different mode. Fluctuations will stop.

Next, the ordinary electric accessory processing in step 114 of FIG. 7 will be described with reference to the subroutine shown in FIG. First, here, a case will be described in which a long-time winning symbol occurs in the symbol variation process shown in FIG. 9, and "1" is set to the long-term flag and the winning flag. When the normal electric accessory processing shown in FIG. 12 is started, first, the CPU circuit 57 determines whether or not the hit flag is “1” (S350), and here, the determination in step 350 is Yes, and Electric accessory 32
It is determined whether it is open (S352). This step 352
Is No, and it is determined whether the long time flag is "1" (S
354). Here, the step 354 becomes Yes, and a long time (about 5.8 seconds) is set in the timer 1 which sets the opening time of the ordinary electric accessory 32 (S356). After that, the CPU circuit 57 sets the long time flag to “0” (S
360), the first solenoid 82 that opens and closes the ordinary electric accessory 32 after starting the timer 1 (S362) (see FIG. 2).
Is turned off to open the ordinary electric accessory 32 (S36).
4) Then, this subroutine process is completed.

Next, the normal electric accessory processing shown in FIG. 12 after the normal electric accessory 32 is opened in step 364 will be described. First, the CPU circuit 57 determines whether or not the hit flag is "1" (S350), and here,
The determination in step 350 becomes Yes, and it is determined whether the normal electric accessory is being opened (S352), but this step 3
52 becomes Yes, and it is determined whether or not the above long time (about 5.8 seconds) set in the timer 1 has timed up (S3).
66). Here, before the above-mentioned long time (about 5.8 seconds) has elapsed (No in S366), this subroutine processing is ended and the opening of the ordinary electric accessory 32 is continued.

By opening the ordinary electric accessory 32 for the long time (about 5.8 seconds), three gaming balls can be won with a very high probability. Then, as described above with reference to FIGS. 3 and 4, when the winning detection switch 62 detects the third winning, the first actuating solenoid 85 is operated and the stopper 64 is moved to the rear side as shown in FIG. Pull in to. As a result, the third winning ball temporarily stops in the guide rail 66.

When this long time (about 5.8 seconds) elapses,
The judgment step 366 is YES if the timer 1 time is up
And the hit flag is set to "0" (S368). Then, the CPU circuit 57 uses the first solenoid 8 shown in FIG.
2 is excited and the ordinary electric accessory 32 is closed. As shown in FIGS. 3 and 4, when the ordinary electric accessory 32 is closed, the second actuating solenoid 86 receives it and raises the guide rail 66 upward. Accordingly, when the third winning ball is held in the guide rail 66, it is detected by the special device operating switch 69. When the winning ball is detected by the special device operating switch 69, the step 372 of passing the special device operating area becomes Yes, the right generation flag is set to "1" (S374), and the special winning opening 24
The variable p representing the number of times of release of the is set to "1" (S37
6) Then, this subroutine process is terminated.

Next, the right generation processing in step 116 of FIG. 7 will be described with reference to the subroutine shown in FIG. Here, the process after the right generation flag is set to "1" in step 374 will be described. C
The PU circuit 57 determines whether the right generation flag is "1" (S400), but here, the step 400 is Yes.
Therefore, it is determined whether the jackpot flag is "1" (S4
02), here the step 402 becomes No and the process proceeds to step 404, and it is determined whether or not the game ball is detected by the third type starting port switch 74 provided in the third type starting port 25 shown in FIG. 5 (S404). . Here, until the game ball is detected at the third type starting opening 25, the step 404 becomes No and the subroutine processing is ended. On the other hand, as shown in FIG. 5 (B), the game ball wins the third type starting opening 25, that is, fits in the recess 22a of the rotary chucker 22, is conveyed downward by the rotation of the rotary chucker 22, and passes through the rotary chucker. When it is detected by the third-type starting opening switch 74 via the opening 23, the determination in step 404 becomes Yes. As a result, the CPU circuit 57 sets the jackpot flag to "1" (S406) and the opening time of the special winning opening 24 is about 9.8.
The timer 2 for setting the second is started (S408), the excitation of the second solenoid 84 shown in FIG. 6 is turned off to open the special winning opening 24 (S410), and the subroutine processing is ended.

Next, the right generation processing shown in FIG. 13 after the special winning opening 24 is opened in step 410 will be described. First, the CPU circuit 57 determines whether or not the right generation flag is "1" (S400). Here, the determination in step 400 is Yes, and it is determined whether or not the jackpot flag is 1 (S402). If Yes in 402, it is determined whether or not about 9.8 seconds set in the timer 2 has elapsed (S412). Where timer 2
Is not up (S412 is N
o), based on the output of the ten count switch 76 shown in FIG. 5B, it is determined whether the number of winnings from the special winning opening 24 is less than 10 (S414). If the timer 2 has not timed out and the number of winnings is less than 10, (S
412 is No and S414 is Yes), the processing is terminated and the special winning opening 24 is continuously opened. On the other hand, when the timer 2 has timed up (S412 is Yes) or the number of winnings is 10 or more (S414 is No), the process proceeds to step 416 to excite the second solenoid 84 to open the big winning opening 24. Close once. Then, the jackpot flag is set to "0" (S
418). Then, it is determined whether the variable p representing the number of times the special winning opening 24 has been opened is less than 16, that is, whether the special winning opening 24 has been opened 16 times (S420). Here, since the special winning opening 24 has been opened once, the step 420 returns Yes.
Then, the process shifts to step 422, 1 is added to the variable p, and the process is terminated. Repeat the above process and win the big prize 2
When 4 is released 16 times, the judgment in step 420 is N
Then, the process proceeds to step 424, the right generation flag is set to “0”, and then 1 is set in the variable m representing the number of times the right state is generated.
Is added (S426). In the above example, the variable m is an even number,
That is, the probability of occurrence of a hit was in the low probability state, whereas 1 is added to the variable m in step 426 to make it an odd number, that is, the high probability state is entered and the subsequent processing is advanced. .

Here, the processing after the transition to the high probability state will be described. The game ball passes through the normal symbol operation gate 21, and the symbol variation process when the variable U becomes 1 by the gate passage process (S110 shown in FIG. 7) will be described with reference to FIG. 9 again. First, the CPU circuit 57 determines whether or not the symbol of the normal symbol display device 34 is changing (S20).
2) Here, since the symbol is not changing (No in S202), it is determined whether U is 1 or more (S204), but here, since U is 1 (Yes in S204), from this variable U 1 is subtracted (S206). Then, the variation of the symbol of the normal symbol display device 34 is started (S208). Subsequently, the CPU circuit 57 determines whether or not the variable m indicating the number of times the special device has been operated, that is, the number of times the right state has occurred is an odd number (S210). Here, as described above, m
Is an odd number, that is, a high probability state (S210
Yes), the process proceeds to step 214.

In step 214, a hit random number for generating a hit with a high probability is set. That is, FIG. 15 (A)
"7" and "1" of 20 frames from 0 to 19 shown in
By setting "1" to "19" as a hit, 1
It is adjusted so that a hit is generated with a probability of / 2 (10 times as low as the low probability state). Then, the hit is determined by the set random number value (S216). Here, when the hit occurs (Yes in S216), the hit symbol is selected (S218). That is, one of the random numbers of 231 frames from 0 to 230 shown in FIG. 15B is selected. Here, the following description will be continued on the assumption that the random number “2” (corresponding to the red number 022) is selected. Next, it is determined whether or not this hit is a long-time design that normally opens the electric accessory 32 for a long time, or a short-time design that opens only a short time (S220). Here, the random number “2” is selected as described above, and the red number 022, which is a symbol corresponding to the random number “2”, corresponds to the symbol per short time period described above with reference to FIG. 14C. Therefore, step 220 becomes No, the process proceeds to step 224 without setting 1 for the long time flag, and the hit flag is set to "1". Next, the CPU circuit 57 selects a reach random number in the same manner as described above (S226), and sets this selected value in the reach variable r (S228). The symbol timer is set in correspondence with the reach variable r (S230), and the subroutine of this symbol variation process is ended.

Here, the processing after the hit flag is set to "1" will be described. When the ordinary electric accessory processing shown in FIG. 12 is started, first, the CPU circuit 57.
Judges whether the hit flag is "1" (S35
0), here, the determination in step 350 becomes Yes, and it is determined whether or not the normal electric accessory is being opened (S352).
Here, step 352 is No, and it is then determined whether the long time flag is "1" (S354). Here, since the long time flag is "0", the step 3
54 becomes No, and a short time (about 0.85 seconds) is set in the timer 1 which sets the opening time of the ordinary electric accessory 32 (S
358). Then, the timer 1 is started (S362).
After that, the first solenoid 82 for opening and closing the ordinary electric accessory 32
The excitation of (see FIG. 2) is cut off to open the ordinary electric accessory 32 (S364), and this subroutine processing is terminated.

Next, the normal electric accessory processing shown in FIG. 12 after the normal electric accessory 32 is opened in step 364 will be described. First, the CPU circuit 57 determines whether or not the hit flag is "1" (S350), and here,
The determination in step 350 becomes Yes, and it is determined whether the normal electric accessory is being opened (S352), but this step 3
54 becomes Yes, and it is determined whether or not the short time (about 0.85 seconds) set in the timer 1 has timed up (S
366). Here, before the short time (about 0.85 seconds) elapses (No in S366), this subroutine processing is ended and the normal electric auditors product 32 is continuously opened.

When this short time (about 0.85 seconds) elapses, Step 366 of timer 1 time up is Yes.
And the hit flag is set to "0" (S368). Then, the CPU circuit 57 uses the first solenoid 8 shown in FIG.
2 is excited to close the ordinary electric accessory 32 (S370).
After that, it is determined whether or not the game ball has passed the special device operating area (S372), and if the game ball has not passed the special device operating area (S372 is No), the process ends.

By opening the ordinary electric accessory 32 for a short time (about 0.85 seconds), one or two game balls are usually won in the ordinary electric accessory 32. 13 game balls are paid out for the winning prize. After transitioning to the high probability state, each time the game ball passes through the normal symbol actuation gate 21, there is a 1/2 probability (10 in the low probability state).
Double) A short-term design or a long-term design will cause a hit. To be precise, 210 of the 231 ways of winning by the symbol per short time, and 21 of 231 ways of winning by the symbol per long time,
That is, the number of hits due to the symbols per short time is 10 times as large as that of the symbols per long time. Therefore, in this high-probability state, the hits due to the hit symbols frequently occur for a short time, and the prize balls are paid out in small increments. Therefore, the player who has received a large number of gaming balls due to the occurrence of the right state enjoys the game without reducing the number of balls held until the next long time hit by the symbol occurs and the right state occurs. be able to.

Also, even during the opening of the normal electric accessory 32 for 0.85 seconds per symbol for this short time, depending on the flowing state of the game balls on the board, three game balls win the prize and the right state Can occur. Therefore, the expectation of the right generation can be given to the player each time the normal electric accessory 32 is opened, and the motivation for the game can be further enhanced.

The length of the opening time of the ordinary electric accessory (specific winning opening) is not limited to the above-mentioned embodiment, and the opening time is not limited to two types and may be a plurality of types depending on the winning symbol. Further, the appearance probability of the hit by the symbol for a short time and the hit by the symbol for a long time is not limited to that of the embodiment. Further, in this embodiment, the case where the high-probability state and the low-probability state are alternately generated has been described, but the present invention is not limited to this example. For example, a game in the high-probability state is operated in the low-probability state. It may be performed a plurality of times after the end. Furthermore, in the above-mentioned embodiment, the example in which the symbol variation is generated by the passage of the normal symbol actuation gate 21 of the game ball has been described, but instead of this, it is configured to start the symbol variation by the winning of the starting opening. Is also possible.

[0046]

[Effect] As described above, according to the present invention, it is possible to generate a hit of a symbol and to change the probability of the third hit.
In the seed pachinko machine, the specific winning opening is repeatedly opened for a short time under the high probability state, so that the ball can be held until the right state is generated. In addition, it is possible to increase the player's expectation for the occurrence of the right by frequently opening the specific winning opening.
