That is, when it is expected that the payout rate does not exceed three times, the occurrence of a big hit is allowed, and when it is expected to be three times or more, no big hit is generated.

Here, the operation of the game control device 50 for performing the game by the pachinko machine will be described with reference to the flowcharts of FIGS.
A main processing procedure of the game control device 50 will be described with reference to a flowchart of FIG. 5 showing a main routine.

{Circle around (1)} First, the CPU 84 determines whether or not the power is turned on (S100). Only the first loop immediately after the power is turned on (S100: Yes) proceeds to step 102, performs initial settings, and ends the main routine. Here, when it is determined that the power is not turned on (S100: No), a signal about a winning ball or the like from the winning ball detection switch 45 (see FIG. 4) or the like is input to prepare a form that can be used in another phase. An input process is performed (S200), and an output process of outputting the output-edited output data to the accessory concentration boards 66 and 67 and the payout control board 37 (see FIG. 4) is performed (S300).

Subsequently, a normal symbol starting process, which is a process for a game ball that has passed through the normal symbol operation gate 40 (see FIG. 2), is performed (S400), and a normal symbol for changing the symbol of the normal symbol display device 32 with the gate passing process. -The normal electrical combination control process is performed (S600).

Further, a special symbol starting process, which is a process for a game ball that has passed through the first type starting port 41 (see FIG. 2), is performed (S500). A special symbol change process for changing symbols is performed (S700). Then, a special winning opening control process for opening the special winning opening 51 according to the occurrence of a hit is performed (S800). Then, a payout rate calculation process of calculating a payout rate when a big hit is generated is performed (S900).

(4) Subsequently, a lamp and LED lighting process is performed (S104). Finally, the sound output processing for outputting sound via the upper speaker board 78 is advanced (S106), and the one-cycle main routine processing is completed. The main routine is repeated every machine cycle in which a reset signal from a built-in clock is applied to the CPU 84.

Here, the ordinary symbol starting process in the above-described step 400 based on the passing of the game ball to the ordinary symbol operation gate 40 will be described with reference to a subroutine shown in FIG.

The CPU 84 determines whether or not a game ball has passed the normal symbol operation gate 40 based on a signal from the normal symbol operation switch 40a (S402). If the game ball has not passed (S402: No). Then, the ordinary symbol start subroutine is terminated. On the other hand, when the game ball has passed (S402: Yes), it is determined whether or not the normal symbol operation storage number W is less than 4 (S404). Here, the variable W indicates the number of game balls that have passed through the ordinary symbol operation gate 40 during the symbol change of the ordinary symbol display device 32. In the present embodiment, the number exceeding 4 is not held as described above. Is configured. Therefore, when the variable W is 4 (S404: No), the subroutine ends.

On the other hand, if the variable W is less than 4 (S404: Yes), 1 is added to the variable W (S406), and the current timing in the normal symbol random number of 24 frames from 0 to 23 shown in FIG. The value at the time when the game ball normally passes through the symbol actuation gate 40 is extracted (S408), and this value is retained, and the starting opening winning subroutine ends. As will be described later, out of the 24 normal symbol random numbers "0" to "23", "0" to "20" are missed, and "21" to "23" are hits (probability 3/24). .

(4) When the game ball passes through the gate 40, a normal symbol / ordinary electric hand control process for variably displaying the ordinary symbol by the ordinary symbol display device is executed (S600). This normal symbol / ordinary electric hand control process will be described with reference to the flowchart of FIG.

{Circle around (1)} First, it is determined whether or not the ordinary electric utility is operating (S602). Before activating the ordinary electric combination (S602: No), the process proceeds to step 610, and it is determined whether or not the ordinary symbol is operated by the ordinary symbol display device. Here, before changing the normal symbol (S610: No), the process proceeds to step 624, and it is determined whether or not the number of the normal symbol operation memory is one or more (S624). Here, if one or more are stored (S624: Yes), the process proceeds to step 626. Then, the operation memory is reduced by one (S626), the symbol of the ordinary symbol display device 32 starts to change, and the left red diode 32a, the middle green diode 32b, and the right red diode 32c are turned on (S628).

Subsequently, after starting the fluctuation timer for setting the fluctuation time (S630), the process proceeds to step 634, where the value of the ordinary symbol random number stored in step 408 is viewed, and the random number value corresponds to an outlier (0 to 20). If it has been performed (S634: No), the process proceeds to step 642, where a lost symbol is selected, and when the symbol is normally stopped, the selected lost symbol is displayed. On the other hand, when the random number value corresponds to the hit (21 to 23) (S634: Yes), the process proceeds to step 638 to set the hit symbol, thereby displaying the selected hit symbol when the normal symbol is stopped. Finally, the hit flag is turned ON (S640).

(4) When the fluctuation timer starts and a stopped symbol is selected, in the next machine cycle, it is determined in step 610 whether the ordinary symbol is changing or not is Yes. Accordingly, the process proceeds to step 612, where it is determined whether or not the fluctuation timer in which the fluctuation time of the ordinary symbol is set has expired. Here, until the time is up (S612: No), the process proceeds to step 622, and the symbols continue to fluctuate. Then, when the fluctuation timer enters the time-up state (S612: Yes), the process proceeds to step 614, where the CPU 84 sets the winning symbol set in step 638 by the left red diode 32a, the middle green diode 32b, and the right red diode 32c. Alternatively, the lost symbol set in step 642 is displayed.

Thereafter, the flow advances to step 616 to determine whether or not the hit flag is ON. Here, if the hit flag is ON (S616: Yes), the operation proceeds to step 618 to start the operation of the ordinary electric hand, and proceeds to step 620 to set the operation time (0.2 seconds) of the ordinary electric hand. Start.

In the next machine cycle, when it is determined in step 602 whether or not the normal electric hand is operating, when the normal electric hand is activated (S602: Yes), the process proceeds to step 604, and the operation timer of the normal electric hand is set to time. Determine whether it is up. Here, when the time is up (S604: Yes), the process proceeds to step 606 to terminate the operation of the ordinary electric hand, and proceeds to step 608 to turn off the hit flag.

Next, the change processing of the special symbol display device of step 500, step 700, and step 800 shown in FIG. 5 described above based on the winning of the first type starting port 41 or the above-described ordinary electric accessory 42 will be described with reference to FIGS. This will be described in detail based on the subroutine of FIG.

First, the special symbol starting process in step 500 will be described with reference to a subroutine shown in FIG. The CPU 84 determines whether or not a game ball has won the first-type starting port 41 based on a signal from the first-type starting port switch 41a (S502). If no game ball has been won (S502). : No), the special symbol start subroutine ends. On the other hand, when the game ball is won (S502: Yes), it is determined whether the start storage variable U is less than 4 (S504). Here, the variable U indicates the number of game balls that have won the first-type starting port 41 during the symbol change on the special symbol display device 34, and in this embodiment, the number exceeding 4 is held as described above. Is configured not to be. Therefore, when the variable U is 4 (S504: No), the subroutine ends.

On the other hand, if the variable U is less than 4 (S504: Yes), after adding 1 to the variable U (S506), the current timing in the special jackpot random number of 330 frames from 0 to 329 shown in FIG. The value at (when the game ball wins the first kind opening 41) is extracted (S508), and this value is retained, and the starting opening winning subroutine ends. As described later, in the present embodiment, the random number “7” is set as a jackpot, and a jackpot is generated with a probability of 1/330 in principle.

Next, the payout rate calculation processing in step 900 of FIG. 5 will be described with reference to the flowchart shown in FIG.
First, the number of shooting spheres per unit hour is calculated (S902). Next, the number of acquired balls when a big hit occurs at the present time is calculated (S904). This number of obtained balls is obtained by adding the number of balls to be hit with the jackpot to the average base (average number of balls per minute excluding the number of balls per minute: 35 in this embodiment) corresponding to the model of the pachinko machine. It is calculated by: The number of payouts associated with the jackpot is also an average number (2400 in the present embodiment) corresponding to the model. For example, when 40 minutes have elapsed since the game was started, “7” is acquired as a jackpot special random number, and if jackpots have occurred 5 times in the past 40 minutes, 2400 × 5 (times) +35 (pieces) ) × 40 minutes = 13400. Here, further, the number of payouts at the time of the occurrence of the jackpot is 15800 pieces, which is obtained by adding 2400 pieces of one hit to 13400 pieces. The timing for calculating the number of fired balls and the number of obtained balls is the time when the vehicle has passed through the starting port switch. This is the same for the following embodiments.

Subsequently, the payout rate is calculated by dividing the acquired number calculated in step 904 by the number of shots per hour calculated in step 902 (S906). In this case, 2.63 is obtained from 15800/6000 pieces. Then, it is determined whether or not the calculated payout rate exceeds 3 (S908). Here, since the payout rate is 2.63 and does not exceed 3 (S908: No), the suppression flag for suppressing the occurrence of the big hit is turned off (S912).

On the other hand, if 50 minutes have passed and six jackpots have occurred in the past 50 minutes, then 2400 pieces × 6 (times) +35 (pieces) × 50 minutes = 16150. Here, furthermore, the number of payouts at the time of the occurrence of the jackpot becomes 18550 pieces obtained by adding 2,400 pieces of one big hit to 16150 pieces. For this reason, when the payout rate is calculated in step 906, 3.09 is obtained as 18550/6000 pieces. Here, since the payout rate exceeds 3.0 at 3.09 (S908: Yes), the suppression flag for suppressing the occurrence of the jackpot is turned on (S910). In the present embodiment, when calculating the payout rate in step 906, the payout rate is calculated by dividing by the number of shots per hour (6000). For example, when calculating in 40 minutes, 40 minutes is required. , And when calculating in 50 minutes, it is also possible to divide by 50 minutes.

Next, the special symbol changing process in step 700 of FIG. 5 will be described with reference to the flowchart shown in FIG.
Here, the processing when the game ball does not win the first type starting port 41, that is, when the variable U is 0 will be described. First, the CPU 84 determines whether the symbol of the special symbol display device 34 shown in FIG. 3 is changing (S702 shown in FIG. 9). Since the special symbol display device 34 is not changing here (S702: No), It is determined whether the variable U is "1" or more (S718). Here, since the variable U is 0 (S718: No), the subroutine of the special symbol variation process ends.

Next, a description will be given of a process when a game ball wins in the first-type starting port 41 and the variable U becomes 1. The determination in step 702 as to whether the special symbol display device 34 is changing is No, and after the determination in step 717, the CPU 84 determines whether the variable U is “1” or more (S718), but the variable U is 1. Therefore, "1" is subtracted from the variable U (S720: Yes). Then, the symbol change of the special symbol display device 34 is started (S722).

Then, the CPU 84 first determines whether or not the random number value set in the above-described step 508 is a jackpot random number value “7” (S726). Here, when the random number value is “7” (S726: Yes), it is subsequently determined whether or not the suppression flag for suppressing occurrence of a big hit is set when the payout rate exceeds 3 (S728). . Here, when the inhibition flag is not set (S728: No), after setting the special symbol jackpot flag (S730), a jackpot symbol such as 111 or 333 is selected (S732). Then, the reach mode is set as the stop mode (S737), and a special figure fluctuation timer for setting the fluctuation time of the special symbol is started (S738).

On the other hand, when the above-mentioned jackpot determination (S726) is No, the random number value of the jackpot is “7”, but when the payout rate exceeds 3 and the inhibition flag is set. (S728: Yes), the process proceeds to step 734, where a lost symbol selection process for selecting a lost symbol such as 123 or 124 is performed, and it is determined whether the selected lost symbol is a reach symbol (S735). If the lost symbol is a reach symbol such as 114 or 223 (S735: Yes), the process proceeds to step 737 to set the reach mode. On the other hand, when the symbol is not the reach symbol (S735: No), the process proceeds to step 736. After the symbol variation is stopped in the off mode, the special figure variation timer is started (S738).

When the symbol change of the special symbol display device 34 is started in the above-described step 722, in the next machine cycle, in the determination in step 702, it is determined whether the symbol is being changed, and the CPU 84 first proceeds to the above-described step 738. It is determined whether or not the symbol fluctuation timer set in the above has timed out (S704). Here, until the symbol stop timer times out due to the elapse of the fluctuation time (S704: No), the fluctuation of the symbol is continued (S716).

Then, when the symbol variation timer times out (S704: Yes), the CPU 84 stops the symbol variation in each variation stop mode (S706). That is, when a normal loss which is not the reach mode is set, a normal symbol stop is performed, and when the reach is set, the symbol variation is stopped in the reach mode.

The special winning opening control process in step 120 of FIG. 5 will be described with reference to a subroutine shown in FIG.
First, it is determined whether the big hit flag is set (S801: Yes), and it is determined whether the big winning opening is open (S802). Since the big winning opening is not open in the first operation (S802: No). Proceeding to step 804, it is determined whether it is the interval time after opening. In the first case, since it is the interval time after the determination of the big hit (S804: No), the process proceeds to step 806, and it is determined whether R = 16. Here, R is incremented by 1 when passing through a specific area after the end of 1R in the number of rounds. Since this is still R = 0 at this point (S806: No), the process proceeds to step 808, and the after-determination interval time timer is set. Determine if the time is up. Here, the post-judgment interval time is the time from when the big hit is determined to when the big winning opening is opened. When the set time has been reached (S808: Yes), the process proceeds to step 810, where an instruction for a special winning opening command is issued to open the special winning opening.

In the next machine cycle, it is determined whether or not the special winning opening is being opened in step 802. Since the special winning opening is now open (S802: Yes), the process proceeds to step 812. In step 812, it is determined whether or not the special winning opening time timer has expired. Here, since the big winning opening has just been opened (S812: No), the process proceeds to step 816. In step 816, it is determined whether the count SW is ON. Here, if it has not passed through the count switch (S816: No), the process ends. On the other hand, if the vehicle has passed (S816: Yes), the process proceeds to step 818, where it is determined whether R = 15. Here, since the opening of the special winning opening is the first (S818: No), the process proceeds to step 820, and it is determined whether the specific area SW is ON. In this step 820, if the game ball has passed through the specific area when winning in the special winning opening 51 (S820: No), the process proceeds to step 822, and if not (S820: Yes), the process proceeds to step 824. Here, the description is continued assuming that the vehicle has passed (Step 820: Yes). With the passage, the specific area SW is turned on (S822). Next, it is determined whether or not the count number is ≧ 9, that is, whether or not approximately nine game balls have won the special winning opening. When 9 is counted by the winning in the special winning opening (S824: Yes), the process proceeds to step 826, where an instruction of a special winning opening closing command is issued, and the special winning opening 51 is once closed. Then, the process proceeds to step 828, where it is determined whether the specific area SW is in the ON state. Here, since it is in the ON state as described above (S828: Yes), the process proceeds to step 830, and the specific area SW is set to the OFF state. Subsequently, the process proceeds to step 832, where the count of winning the special winning opening is reset, and then the process proceeds to step 834, where R = R + 1. As described above, R indicates the number of open rounds, and if the special winning opening is closed and the specific area SW is ON, it is counted as one time.

で In the next machine cycle, since it is the interval time after release in step 804, which is the interval time after release (S804: Yes), the process proceeds to step 846. When the interval time after opening has reached the timer time-up (step 846: Yes), the process proceeds to step 810 to open the special winning opening again.

Next, the flow of processing when the opening of the special winning opening is repeated 16 times will be described. At the 16R, R = 15 since the winning opening has been continuously opened 15 times. First, assuming that the special winning opening is open (S802: Yes), the process proceeds to step 812. Until the special winning opening time timer expires (S812: No), the process proceeds to step 814 to determine whether the count SW is ON. If it has passed the count switch (S814: Yes), the process proceeds to step 816, where it is determined whether R = 15. Here, since R = 15 (S816: Yes), the process proceeds to step 824 without turning the specific area SW on. If it is determined in step 824 that the count number ≧ 9 (S824: Yes), the flow advances to step 826 to output an instruction for a special winning opening closing command, and then to step 828 to determine whether the specific area SW is in the ON state. I do. As described above, since R = 15 and the specific area SW is not in the ON state (S828: No), the process proceeds to step 836, where R = 16.

In the next machine cycle, in the judgment as to whether or not the special winning opening is being opened in step 802, since the current state is that the final round has been completed (S802: No), the process proceeds to step 804. Since it is determined in step 804 whether the interval time is after the release, the current state is that the big hit ends and the end delay time starts (S804: No), and the process proceeds to step 806. Since it is determined at this time that R = 16 in step 806 (S806: Yes), the flow advances to step 848 to determine whether the end delay time timer has expired. Here, if the time is not up (S848: No), the process ends. On the other hand, if the time is up (S848: Yes), the process proceeds to step 850, where R is reset and the big hit flag is turned off (S852).

In the pachinko machine of the first embodiment, it is determined whether the ratio between the number of obtained balls and the number of fired balls exceeds a predetermined value, and when it is determined that the ratio exceeds the predetermined value, a big hit is not generated. . For this reason, it is possible to keep the payout rate below a predetermined value. In the first embodiment, one type of pachinko machine is exemplified. However, in the case of three types of pachinko machines, when the payout rate exceeds a predetermined value due to the occurrence of a hit in a normal symbol, the same type of pachinko is similarly suppressed. By setting the flag, occurrence of hits can be suppressed, and the payout rate can be kept below a predetermined value.

[Second embodiment]
Subsequently, a pachinko machine according to a second embodiment of the present invention will be described. The pachinko machine of the second embodiment is configured as a probabilistic machine, and shifts to the high probability state with an odd jackpot symbol such as 111, 333, 555, and the like, which is normally generated with a probability of 1/330 at normal times. , The next jackpot is generated with a probability of 1/110. On the other hand, a big hit which does not shift to a high probability is generated with an even big hit design such as 222, 444, 666. Here, in the above-described first embodiment, when the payout rate exceeds 3, occurrence of a big hit is suppressed. On the other hand, in the second embodiment, when the payout rate exceeds 3, occurrence of a jackpot that shifts to a high probability is suppressed.

The processing of the CPU 84 in the pachinko machine of the second embodiment is the same except for the special symbol variation processing described above with reference to FIG. 9 and the payout rate calculation processing described above with reference to FIG. Therefore, only the payout rate calculation processing and the special symbol change processing will be described. First, since the flow of the payout rate calculation processing is the same as that of the first embodiment, the processing will be described with reference to the flowchart shown in FIG.

First, the number of shot balls per hour in the past is calculated (S902). Next, the number of acquired balls when a big hit occurs at the present time is calculated (S904). The number of obtained balls is an average base corresponding to the type of the pachinko machine (the average number of balls per minute except for the number of balls per minute: in the present embodiment, 35 at a low probability, and at a high probability, a hit by an ordinary symbol). Is calculated by adding the number of payouts associated with the jackpot to (100 when the occurrence rate is improved). The number of payouts associated with the jackpot is also an average number (2400 in the present embodiment) corresponding to the model. For example, if 30 minutes have elapsed since the start of the game and four big hits have occurred in the past 30 minutes, 2400 × 4 (times) +35 (pieces) × 30 minutes = 10650. Here, the number of payouts at the time of the occurrence of the jackpot that shifts to the high probability is 15450, which is obtained by adding 4800 pieces of two jackpots to 10650 pieces. In other words, the transition to the high probability means that the jackpot substantially lasts twice in a short period of time. Therefore, 4800 pieces of the expected number of acquisitions are added.

Subsequently, the payout rate is calculated by dividing the acquired number calculated in step 904 by the number of shots per hour calculated in step 902 (S906). In this case, 2.58 is obtained from 15450/6000. Then, it is determined whether or not the calculated payout rate exceeds 3 (S908). Here, since the payout rate is 2.63 and does not exceed 3 (S908: No), the suppression flag for suppressing the occurrence of the jackpot of the transition to the probable change is turned off (S912).

On the other hand, if 40 minutes (35 minutes in the low-probability state, 5 minutes in the high-probability state) have elapsed and 5 jackpots have occurred in the past 40 minutes, 2400 × 5 (times) +35 (pieces) × 35 (minute: low probability time) + 100 × 5 (minute: high probability time) = 13725. Further, the number of payouts at the time of occurrence of the jackpot which shifts to the high probability becomes 18525, which is obtained by adding 4800 pieces of two jackpots to 16150 pieces. For this reason, when the payout rate is calculated in step 906, 3.09 is obtained from 18525/6000 pieces. Here, since the payout ratio exceeds 3.0 at 3.09 (S908: Yes), the suppression flag for suppressing the occurrence of the jackpot that shifts to the high probability is turned on (S910). In the present embodiment, when calculating the payout rate in step 906, the payout rate is calculated by dividing by the number of shots per hour (6000). For example, when calculating in 30 minutes, 30 minutes is used. , And when calculating in 40 minutes, it is also possible to divide by 40 minutes.

Subsequently, the special symbol change processing of the second embodiment will be described with reference to FIG.
Here, the processes from step 702 to step 722 are the same as those in the first embodiment described above with reference to FIG.
In step 723, it is determined whether the extracted jackpot special random number value is a value that becomes a jackpot. Here, in the low probability state, when “7” is set (probability 1/330) out of 330 random numbers from 0 to 329 shown in FIG. 12A, it is determined that the value is a predetermined value (S723: Yes), proceed to step 724 to set a special symbol jackpot flag. On the other hand, in the high probability state, when “7”, “107”, and “207” are set (probability 1/1100) out of the 330 random numbers from 0 to 329 (S723: Yes), proceed to step 724 to set a special symbol jackpot flag. Thereafter, when the high probability flag indicating the high probability state is set, the high probability flag is reset (S725).

The CPU 84 subsequently determines whether the inhibition flag is set (S726). Here, as described above, when the suppression flag is set assuming that the payout rate exceeds 3 due to the occurrence of the jackpot that shifts to the high probability (S726: Yes), the process proceeds to step 732.

On the other hand, when the inhibition flag is not set (S726: No), the process proceeds to step 727, and determines whether or not to generate a jackpot that shifts to a high probability. Select one of Then, it is determined whether the selected high-probability random number is 1 (S728). In the case of 1 (S728: Yes), a high-probability flag for generating a jackpot that shifts to a high probability is set (S729). On the other hand, when the selected high-probability random number is 0 (S728: No), the process proceeds to step 732.

In step 723, a big hit symbol is selected based on the high probability flag. That is, when the high probability flag is not set, an even number of big hit symbols of 000,222,444,666,888 are selected. On the other hand, when the high probability flag is set, the odd big hit symbols of 111,333,555,777,999 are selected. The processing after step 736 is the same as in the first embodiment described above with reference to FIG.

In the embodiment, the jackpot symbol is determined after determining whether to shift to the high probability. Instead of this, for example, an odd number is specified (probable) and an even number is used as a normal symbol, and a jackpot symbol is determined. At the same time, it is determined whether the symbol changes stably. When the suppression flag is ON, one of the even symbols is selected. A decision method of selecting one can be used.

Subsequently, a first modified example of the pachinko machine of the second embodiment will be described with reference to FIGS.
In the above-described second embodiment, the jackpot that shifts to the high probability and the jackpot that does not shift to the high probability are generated in the symbols on the special symbol display device 35. On the other hand, in the first modified example, whether or not to shift to the high probability is determined according to the content of the determination symbol. In the first modification, similarly to the above-described second embodiment, when the payout rate exceeds 3, the occurrence of a determination symbol that shifts to a high probability is suppressed.

The configuration of the center case 130 of the pachinko machine according to the first modification of the second embodiment will be described with reference to FIG.
In the center case 130, a winning prize opening 31, a judgment symbol display device 29 for displaying a judgment symbol of either O or X, a normal symbol display device 32 including three LEDs, and the normal symbol display device 32 , A normal symbol storage display LED 33 composed of four LEDs for displaying the number of times of starting, a special symbol display device 34 for displaying a special symbol 34a on a liquid crystal display, and the number of times the special symbol display device 34 is started. And a special symbol storage display LED 35 composed of four LEDs.

The processing of the CPU 84 in the pachinko machine according to the first modification of the second embodiment is the same as that of the first embodiment except for the special symbol change processing described above with reference to FIG. Therefore, only the special symbol change processing will be described with reference to FIG.
Here, the processes from step 702 to step 722 are the same as those in the first embodiment described above with reference to FIG.
In step 723, it is determined whether the extracted jackpot special random number value is a value that becomes a jackpot. Here, in the low probability state, when “7” is set among the random numbers of 0 to 329 (probability 1/330), it is determined that the value is a predetermined value (S723: Yes), and the process proceeds to step 724. , Set the special symbol jackpot flag. On the other hand, in the high probability state, when “7”, “107”, and “207” are set (probability 1/110) out of the 330 random numbers from 0 to 329 (S723: Yes), proceed to step 724 to set a special symbol jackpot flag. Thereafter, when the high probability flag indicating the high probability state is set, the high probability flag is reset (S725).

Steps 732 to 706 are the same as those in the first embodiment described above with reference to FIG. The CPU 84 performs the determination symbol processing of step 1000 following the processing of step 706.

The determination symbol processing will be described with reference to FIG. 16 showing a subroutine of the processing.
First, after determining whether or not the determination symbol treatment has been completed (S1002: Yes), it is determined whether or not the determination symbol display device 29 described above with reference to FIG. 14 is changing (S1004). Here, before the start of the change (S1004: No), the change of the judgment symbol is started (S1006). Then, it is determined whether the symbol variation time has elapsed (S1008). Here, if the fluctuation time elapses (S1008: Yes), if a jackpot that shifts to a high probability occurs, it is determined whether a suppression flag set when the payout rate exceeds 3 is on (S1010).

If the inhibition flag is not set (S1010: No), it is determined whether the selected high-probability random number is 1 (S1016). The high-probability random number that determines whether or not to generate the jackpot that shifts to the high probability is determined in step S1014 of the special symbol start-up process of the second embodiment shown in FIG. Either is selected. When the high-probability random number is 1 (S1016: Yes), a high-probability flag for generating a jackpot that shifts to high probability is set (S1018). On the other hand, when the inhibition flag is set (S1010: Yes), the process proceeds to step 1012, where 0 is set as a high probability random number. Thereafter, a judgment symbol corresponding to the high-probability random number is displayed on the judgment symbol display device 29. When a jackpot that shifts to a high probability is generated, ○ is displayed, and when a jackpot that is not shifted is generated, X is displayed. The configuration of the first modification of the second embodiment described above is also applicable to a two-type machine having a determination symbol.

In the pachinko machine of the second embodiment, it is determined whether the ratio between the number of obtained balls and the number of fired balls exceeds a predetermined value, and when it is determined that the ratio exceeds the predetermined value, a transition to a high probability occurs. Do not let it. For this reason, it is possible to keep the payout rate below a predetermined value.

[Third embodiment]
Subsequently, a pachinko machine according to a third embodiment of the present invention will be described. In the pachinko machine of the third embodiment, when the payout rate is about to exceed 3, the probability of a jackpot per unit time is reduced by increasing the time of symbol change of the special symbol display device, and the payout rate is reduced. adjust. Here, when the payout ratio does not exceed 3, the symbol variation time is adjusted to be 9 seconds on average by setting the variation fixed time to 5 seconds. Thereby, the maximum number of symbol changes per minute is 6.7 times. The winning frequency at the starting opening is low and the special symbol does not fluctuate, and the winning frequency is high and fluctuates continuously. Therefore, the average number of times the symbol fluctuates is about six times. On the other hand, when the payout ratio exceeds 3, the fluctuation fixed time is set to 10 seconds, and the symbol fluctuation time is adjusted so as to average 14 seconds. Thus, the maximum number of symbol changes per minute is 4.3, and the average number of symbol changes is approximately four.

That is, when the payout rate does not exceed 3, the average number of times of change per minute is six, whereas when the payout rate exceeds 3, the average symbol change time per minute is four. When the payout rate does not exceed 3, the probability of occurrence of a big hit per minute becomes 1.5 times. Thereby, in the pachinko machine of the third embodiment, the payout rate is adjusted.

処理 The processing of the CPU 84 in the pachinko machine of the third embodiment is the same except for the special symbol variation processing described above with reference to FIG. 9 and the payout rate calculation processing described above with reference to FIG. Therefore, only the payout rate calculation processing and the special symbol change processing will be described. First, since the flow of the payout rate calculation processing is the same as that of the first embodiment, the processing will be described with reference to the flowchart shown in FIG.

In the third embodiment, in the calculation processing of the number of acquired balls in step 904, the number obtained by adding the counted number of prize balls to 7,200 corresponding to three big hits is used as the number of acquired balls. This prevents the payout rate from exceeding 3 in advance.

The special symbol changing process of the pachinko machine according to the third embodiment will be described with reference to FIG.
Here, the processing from step 702 to step 737 is the same as in the first embodiment described above with reference to FIG.
In step 738, it is determined whether the inhibition flag is set. Here, when the inhibition flag is set (S738: Yes), a long time is set as the fluctuation time of the special symbol fluctuation device as described above (S740). On the other hand, when the inhibition flag is not set (S738: No), a short time is set as the fluctuation time of the special symbol fluctuation device as described above (S742).

In the pachinko machine of the third embodiment, it is determined whether the ratio between the number of obtained balls and the number of fired balls exceeds a predetermined value, and when it is determined that the ratio exceeds the predetermined value, the fluctuation time of the special symbol is extended. I do. For this reason, the number of hits per fixed time is reduced, and the payout rate can be kept below a predetermined value.

[Fourth embodiment]
Subsequently, a pachinko machine according to a fourth embodiment of the present invention will be described. In the pachinko machine of the fourth embodiment, when the payout rate is about to exceed 3, by changing the opening time of the special winning opening, the probability of occurrence per unit time of the big hit is reduced, and the payout rate is adjusted. Here, when the payout rate does not exceed 3, the special winning opening is continuously opened for 30 seconds as shown in FIG. On the other hand, when the payout rate exceeds 3, as shown in FIG. 23B, the opening of the special winning opening for 3 seconds and the closing of the 2 seconds are repeated 10 times. However, if there are 9 winnings during the opening for 30 seconds or the opening and closing for 3 seconds, the winning opening is closed.

In the fourth embodiment, in the calculation processing of the number of acquired balls in step 904, a number obtained by adding 7200 balls corresponding to three big hits to the counted number of winning balls is used as the acquired balls. This prevents the payout rate from exceeding 3 in advance. In other words, when the payout rate exceeds 3, opening and closing the special winning opening reduces the number of symbol changes per unit by the length of the jackpot time. Thereby, in the pachinko machine of the fourth embodiment, the payout rate per unit time is adjusted.

処理 The processing of the CPU 84 in the pachinko machine of the fourth embodiment is the same except for the special winning opening control processing of the first embodiment described above with reference to FIG. Therefore, a description will be given with reference to the flowchart shown in FIG. 18 showing the special winning opening control process. Note that the payout rate calculation processing is the same as that of the above-described third embodiment, and thus the description is omitted.

Steps 801 to 811 are the same as in the first embodiment described above with reference to FIG. At step 812, it is determined whether the inhibition flag is set. Here, when the inhibition flag is set (S812: Yes), it is determined whether it is the 3-second opening interval described above with reference to FIG. 23B (S813). During the opening interval of 3 seconds (S813: Yes), the special winning opening is opened (S814), and for two seconds other than the interval (S813: No), the special winning opening is closed (S815). Also, steps S816 to S836 are the same as in the first embodiment, and a description thereof will be omitted.

In the pachinko machine of the fourth embodiment, it is determined whether the ratio between the number of obtained balls and the number of fired balls exceeds a predetermined value, and when it is determined that the ratio exceeds the predetermined value, the opening time of the special winning opening is determined. Open intermittently. For this reason, it is possible to keep the payout rate below a predetermined value. Here, the special winning opening is intermittently opened, but the opening time of the special winning opening can be adjusted. In the above-described example, the configuration of the fourth embodiment is applied to the first model, but the configuration of the fourth embodiment can be applied to the third model.

[Fifth Embodiment]
Next, a description will be given of a pachinko machine according to a fifth embodiment of the present invention. In the first to fourth embodiments described above, when the payout rate exceeds 3, the opening of the special winning opening due to the jackpot is adjusted. On the other hand, in the pachinko machine of the fifth embodiment, when the payout rate falls below 1/3, the payout rate is increased by increasing the number of times of operation of the ordinary electric accessory 42 shown in FIG. .

Here, when the payout rate exceeds 1/3, a hit of a normal symbol is generated with a probability of 1/10. On the other hand, when the payout ratio is less than 1/3, a hit of a normal symbol is generated with a probability of 97/100, and the normal electric accessory is opened. It is assumed that there is an average of 0.5 prizes in the ordinary electric accessory 42 per one ordinary symbol. If the change time of the ordinary symbol is 5 seconds and the opening time of the ordinary electric accessory is 1 second, the ordinary electric accessory is opened 10 times in 1 minute, and there is an average of 5 balls. If the number of prize balls is 6, 30 × 5 prize balls will be paid out with 6 × 5 prize balls. For this reason, in a model whose average base is as low as 20, even if the jackpot does not occur for a long time, the payout rate does not become 1/3 or less.

In the pachinko machine of the fifth embodiment, the processing of the CPU 84 is the payout rate calculation processing of the first embodiment described above with reference to FIG. 11, and the normal symbol / normal electric accessory control processing described above with reference to FIG. The same applies except for Therefore, a description will be given with reference to the flowchart shown in FIG. 19 showing the payout rate calculation processing of the fifth embodiment.

Steps 902 and 904 are the same as in the first embodiment. Here, in step 906, the number of shot balls calculated in step 902 and the number of obtained balls calculated in step 904 are applied to the following equation.
Number of acquired balls / number of fired balls <1.1 / 3
Number of launch balls-number of acquired balls> 7200

Here, two conditions are observed: the number of obtained balls is less than 1.1 / 3 of the number of fired balls, and the value obtained by subtracting the number of obtained balls from the number of fired balls is less than 7,200. The reason why the second formula is added is that when the store is opened and the launch of the game ball is started, the value may drop below 1.1 / 3 immediately, so as to prevent this.

(4) In step 908, it is determined whether the payout rate is smaller than 1/3. Here, when it is small (S908: Yes), a payout flag for improving the payout rate is set (S910). On the other hand, when the payout rate is greater than 1/3 (S908: No), the payout flag is reset (S912).

Next, with reference to FIG. 20, a description will be given of the normal symbol / ordinary motor combination control process in the pachinko machine of the fifth embodiment. In the fifth embodiment, in step 408 of the ordinary symbol starting process shown in FIG. 6, any one of 100 random numbers from 0 to 99 for determining whether or not a hit is shown in FIG. Is stored.

Steps 602 to 630 are the same as those in the first embodiment described above with reference to FIG. A step 631 determines whether or not the payout flag described above is set. Here, when the payout flag is not set (S631: No), it is determined whether the random number is 90 to 99 (S633), and when it is 90 to 99 (S633: Yes), a hit is generated (S640). . That is, a hit of a normal symbol is generated with a probability of 10/100. On the other hand, when the payout flag is set (S631: Yes), it is determined whether the random number is 3 to 99 (S632), and when it is 3 to 99 (S632: Yes), a hit is generated (S640). That is, a hit of a normal symbol is generated with a probability of 97/100.

In the pachinko machine of the fifth embodiment, it is determined whether the ratio between the number of obtained balls and the number of fired balls is lower than a predetermined value, and when it is determined that the ratio is lower than the predetermined value, the hit rate is increased. For this reason, it is possible to keep the payout rate at or above a predetermined value.

Next, a pachinko machine according to a first modification of the fifth embodiment will be described. In the above-described fifth embodiment, the probability of hitting a normal symbol is improved in order to improve the ball payout ratio. However, in the first modification, the ball payout ratio is adjusted by adjusting the fluctuation time of the normal symbol. Has improved.

Here, when the payout rate exceeds 1/3, the fluctuation time of the ordinary symbol is set to 60 seconds. On the other hand, when the payout ratio is less than 1/3, the fluctuation time of the ordinary symbol is set to 5 seconds. Here, if the hit of the ordinary symbol is generated with a probability of 97/100, the hit occurs almost certainly, and if the fluctuation time is 60 seconds and the opening time of the ordinary electric accessory is 1 second, about once a minute. If there is an average of 0.5 prizes in the ordinary electric accessory 42 and the ordinary electric accessory 42 has an average of 0.5 prizes, there will be approximately 0.5 prizes per minute. On the other hand, when the payout rate is less than 1/3, if the fluctuation time of the ordinary symbol is set to 5 seconds, if the opening time of the ordinary electric accessory is 1 second, the ordinary electric accessory is opened 10 times in 1 minute. , There are 5 balls on average. If the number of prize balls is 6, 30 × 5 prize balls will be paid out with 6 × 5 prize balls. For this reason, even in a model whose average base is as low as 20 and the jackpot does not occur, the payout rate is not reduced to 1/3 or less.

Since the payout rate calculation processing in the pachinko machine according to the first modification of the fifth embodiment is the same as the processing described above with reference to FIG. 19, the normal symbol / normal electric hand combination control processing is illustrated in FIG. Will be explained.

Steps 602 to 630 are the same as those in the first embodiment described above with reference to FIG. A step 631 determines whether or not the payout flag described above is set. Here, when the payout flag is not set (S631: No), 60 seconds is set as the fluctuation time of the ordinary symbol (S632). On the other hand, when the payout flag is set (S631: Yes), 5 seconds is set as the fluctuation time of the ordinary symbol (S633).

In the pachinko machine according to the first modified example of the fifth embodiment, it is determined whether the ratio between the number of obtained balls and the number of fired balls is lower than a predetermined value, and when it is determined that the ratio is lower than the predetermined value, The fluctuation time of Therefore, the number of hits per fixed time increases, and the payout rate can be maintained at a predetermined value or more.

Next, a description will be given of a pachinko machine according to a second modification of the fifth embodiment. In the fifth embodiment described above, the probability of hitting a normal symbol is improved in order to improve the payout rate. In the second modification, the open time of the normal electric accessory is adjusted to make the payout rate. The rate has improved.

Here, when the payout ratio exceeds 1/3, the opening time of the ordinary electric accessory is set to 0.2 seconds. On the other hand, when the payout ratio falls below 1/3, the opening time of the ordinary electric accessory is set to 2 seconds. Here, when the hit of the ordinary symbol is generated with a probability of 97/100, the hit occurs almost certainly, and when the payout rate exceeds 1/3, the fluctuation time is set to 8 seconds, and about 6 seconds per minute. If there are times when the regular electric accessory is opened and there are an average of 0.1 prizes during the opening of the ordinary electric accessory for 0.2 seconds, there will be about 0.6 prizes per minute. On the other hand, when the payout ratio is less than 1/3, the fluctuation time of the ordinary symbol is set to 8 seconds, and the opening time of the ordinary electric accessory is set to 2 seconds. If the ordinary electric accessory is released five times in one minute, and if there is an average of one prize during the opening of the ordinary electric accessory for two seconds, there is an average of five balls in one minute. If the number of prize balls is 6, 30 × 5 prize balls will be paid out with 6 × 5 prize balls. For this reason, even if the jackpot does not occur for a long time in a model having an average base as low as 20, the payout rate will not be reduced to 1/3 or less.

Since the payout rate calculation processing in the pachinko machine according to the first modification of the fifth embodiment is the same as the processing described above with reference to FIG. 19, the normal symbol / normal motor combination control processing is shown in FIG. I will explain.

Steps 602 to 618 are the same as those in the first embodiment described above with reference to FIG. In step 620, it is determined whether the payout flag described above is set. Here, when the payout flag is not set (S620: No), 0.2 seconds is set as the opening time of the ordinary electric accessory (S622). On the other hand, when the payout flag is set (S620: Yes), 2 seconds is set as the opening time of the ordinary electric accessory (S621).

In the pachinko machine according to the second modified example of the fifth embodiment, it is determined whether the ratio between the number of acquired balls and the number of fired balls is smaller than a predetermined value. Increase the opening time of the officials. For this reason, it is possible to keep the payout rate at or above a predetermined value.

Next, a description will be given of a pachinko machine according to a third modification of the fifth embodiment. In the above-described fifth embodiment, the probability of hitting a normal symbol is improved in order to improve the payout rate, but in the third modified example, by increasing the probability of occurrence of a big hit that shifts to a high probability state, The payout rate has been improved.

As shown in FIG. 24, it is determined in step 726 whether the payout flag is set. Here, when the payout flag is not set (S726: No), a high-probability random number is extracted so as to generate a jackpot that shifts to the high-probability state with a low probability (S727). On the other hand, when the payout flag is set (S726:
