[Games with special symbol display device]
When the game ball wins the first type starting port 41 or the opened ordinary electric accessory 42, the symbols of 0-9 are started to change in the display portions 34A, 34B, 34C of the special symbol display device 34, respectively. And when the preset time passes, the fluctuation | variation of a symbol will be stopped in order of 34 A of 1st display parts, 34B of 2nd display parts, and the 3rd display part 34C. Here, when the symbols of the first display unit 34A, the second display unit 34B, and the third display unit 34C are different, it is lost. On the other hand, when the symbols of the first display unit 34A, the second display unit 34B, and the third display unit 34C are the same, a big win is made, and after a stop display for 0.8 seconds, a big hit fanfare sounds, The mouth 51 is opened for about 29.5 seconds to provide a state where the game ball is very easy to win. Even if the 29.5 seconds have passed or the opening time has been reached, the game winning slot 51 is closed by winning approximately nine game balls. While the special winning opening 51 is opened, the special winning opening 51 is opened again by passing through the specific area 53. The maximum number of consecutive opening of the big prize opening 51 is up to 16.

  Here, when the game ball wins further to the first type starting port 41 while the variable display is being performed, the number of winning prizes is stored and sequentially displayed on the special symbol memory display LED 35. Even if the above-mentioned game balls win the first type starting port 41, only the first four are stored, and no more values are held. In the state where the winning is memorized, the fluctuation is started again after the special symbol display device 34 stops the fluctuation.

  In the pachinko machine according to the first embodiment, the special symbol display device described above is adjusted so that the ratio of the number of balls played per hour (the number of prize balls for the number of balls launched) does not exceed three times. To do. That is, when the payout rate is expected not to exceed three times, the jackpot is allowed to be generated, and conversely, when it is predicted that it will be three times or more, the jackpot is not generated.

Here, the operation of the game control device 50 for performing the game by the pachinko machine described above 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.

  First, the CPU 84 determines whether or not the power is turned on (S100), and only the first loop (S100: Yes) immediately after the power is turned on moves to step 102, performs the initial setting, and ends the main routine. If it is determined that the power is not turned on (S100: No), a signal relating to a winning ball from the winning ball detection switch 45 (see FIG. 4) or the like is input, and the signal can be used in other phases. An input process is performed (S200), and an output process of outputting the output data that has been output edited 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 the game ball that has passed through the normal symbol operating gate 40 (see FIG. 2), is performed (S400), and the normal symbol that changes the symbol of the normal symbol display device 32 in accordance with this gate passing process. A normal electric role control process is performed (S600).

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

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

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

  The CPU 84 determines whether or not the game ball has passed through the normal symbol operation gate 40 based on the signal from the normal symbol operation switch 40a (S402), and when the game ball has not passed (S402: No). The normal symbol start subroutine is terminated. On the other hand, when the game ball has passed (S402: Yes), it is determined whether the normal symbol operating memory number W is less than 4 (S404). Here, the variable W indicates the number of game balls that have passed through the normal symbol operation gate 40 during the symbol variation of the normal symbol display device 32, and in this embodiment, the number exceeding 4 is not maintained as described above. It is configured. Therefore, if the variable W is 4 (S404: No), the subroutine is terminated.

  On the other hand, if the variable W is less than 4 (S404: Yes), 1 is added to the variable W (S406), and then the current timing in the normal symbols of 24 frames from 0 to 23 shown in FIG. The value at the time when the game ball passes through the normal symbol operating gate 40 is extracted (S408), and this value is held, and the start opening prize subroutine is terminated. As will be described later, “0” to “20” are out of 24 of the normal symbol random numbers “0” to “23”, and if “21” to “23”, they are winning (probability 3/24). .

  When the game ball passes through the gate 40, a normal symbol / ordinary power control process is executed to display the normal symbol variably on the normal symbol display device (S600). The normal symbol / ordinary power control process will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the normal electronic combination is operating (S602). Before operating the normal electric combination (S602: No), the process proceeds to step 610, and it is determined whether or not the normal symbol is operated by the normal symbol display device. Here, before the normal symbol is changed (S610: No), the process proceeds to step 624, and it is determined whether the normal symbol operation memory is 1 or more (S624). If one or more are stored (S624: Yes), the process proceeds to step 626. Then, the operating memory is decreased by 1 (S626), the change of the symbol of the normal symbol display device 32 is started, 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 and the random number value corresponds to the deviation (0 to 20) by looking at the value of the normal symbol random number stored in step 408. If so (S634: No), the process proceeds to step 642, and the selected symbol is displayed when the normal symbol is stopped by selecting the symbol that is off. On the other hand, when the random number corresponds to the winning (21 to 23) (S634: Yes), the process proceeds to step 638 and the winning symbol is set to display the selected winning symbol when the normal symbol is stopped. Finally, the hit flag is turned on (S640).

  When the variation timer is started and the stop symbol is selected, it is determined in the next machine cycle whether the normal symbol in step 610 is varying. As a result, the routine proceeds to step 612, where it is determined whether or not the variation timer for which the variation time of the normal symbol is set has expired. Here, until the time is up (S612: No), the process proceeds to step 622, and the variation of the symbol is continued. When the variation timer reaches the time-up state (S612: Yes), the process proceeds to step 614, and the CPU 84 determines 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 off symbol set in step 642 is displayed.

  Thereafter, the process proceeds to step 616 to determine whether the hit flag is ON. Here, if the winning flag is ON (S616: Yes), the process proceeds to step 618 to start the operation of the ordinary electric combination, and proceeds to step 620 to set the operation time (0.2 seconds) of the ordinary electric combination. Start.

  In the next machine cycle, in the determination of whether or not the normal power combination is activated in step 602, when the normal power combination is activated (S602: Yes), the process proceeds to step 604, where the normal power combination operation timer is set to the time. Judge whether it is up. Here, when the time is up (S604: Yes), the process proceeds to step 606, the operation of the normal electric combination is terminated, the process proceeds to step 608, and the hit flag is turned OFF.

  Next, regarding the variation process of the special symbol display device in step 500, step 700, and step 800 shown in FIG. 5 described above based on the winning in the first type starting port 41 or the above-described ordinary electric accessory 42, FIG. 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 start port 41 based on a signal from the first type start port switch 41a (S502), and if the game ball has not won (S502). : No), the special symbol starting subroutine is terminated. On the other hand, when the game ball wins (S502: Yes), it is determined whether the start memory variable U is less than 4 (S504). Here, the variable U indicates the number of game balls won in the first type starting port 41 during the symbol variation on the special symbol display device 34. In this embodiment, the number exceeding 4 is held as described above. It is configured not to be. Therefore, if the variable U is 4 (S504: No), the subroutine is terminated.

  On the other hand, if the variable U is less than 4 (S504: Yes), 1 is added to the variable U (S506), and then the current timing in the jackpot special random number of 330 frames from 0 to 329 shown in FIG. The value at the time of winning the game ball to the first type starting port 41 is extracted (S508), this value is held, and the starting port winning subroutine is terminated. As will be described later, in this embodiment, the random number “7” is set as a jackpot, and the jackpot is generated with a probability of 1/330 in principle.

Next, the payout rate calculation process in step 900 of FIG. 5 will be described with reference to the flowchart shown in FIG.
First, the number of shot balls per unit hour is calculated (S902). Next, the number of acquired balls when the jackpot is generated at the present time is calculated (S904). The number of balls to be acquired is the average base corresponding to the model of the pachinko machine (average number of balls excluding the number of balls played per minute: 35 balls in this embodiment), and the number of balls with jackpots is added. Calculated by The number of balls that accompany this jackpot is also the average number corresponding to the model (2400 in this embodiment). For example, if 40 minutes have elapsed since the game was started, “7” is acquired as a special jackpot random number, and if the jackpot has occurred 5 times in the past 40 minutes, 2400 × 5 (times) +35 (pieces) ) × 40 minutes = 13400. Here, the number of balls when the jackpot is generated is 15800, which is 13400, plus 2400 for one jackpot. The timing for calculating the number of shot balls and the number of acquired balls is the time when the start port switch is passed. The same applies to the following embodiments.

  Subsequently, a payout rate is calculated by dividing the number of acquisitions calculated in step 904 by the number of shots per hour calculated in step 902 (S906). In this case, 2.63 is obtained by 15800 ÷ 6000. Then, it is determined whether the calculated payout rate exceeds 3 (S908). Here, since the payout rate is 2.63 and does not exceed 3 (S908: No), the deterrence flag for deterring the jackpot is turned off (S912).

  On the other hand, if the jackpot has occurred 6 times in the past 50 minutes after 50 minutes, 2400 × 6 (times) +35 (times) × 50 minutes = 16150. Here, when the jackpot is generated, the number of balls to be played is 18550, which is 16150, plus 2400 for one jackpot. For this reason, when calculating the payout rate in step 906, 18550 ÷ 6000 pieces, 3.09 is obtained. Here, since the payout rate exceeds 3.0 at 3.09 (S908: Yes), a suppression flag for suppressing the occurrence of jackpot is turned on (S910). In this embodiment, when calculating the payout rate in step 906, it is calculated by dividing by the number of fires for one hour (6000). For example, when calculating in 40 minutes, 40 minutes It is also possible to divide by the number of firings of 50 minutes when calculating in 50 minutes.

Next, the special symbol variation 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 has not won 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). However, since the special symbol display device 34 is not changed 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 special symbol variation process subroutine is terminated.

  Next, a process when a game ball is won at the first type starting port 41 and the variable U becomes 1 will be described. The determination in step 702 whether the special symbol display device 34 is changing is No, and through 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 (S718: Yes), “1” is subtracted from the variable U (S720). And the fluctuation | variation of the symbol of the special symbol display apparatus 34 is started (S722).

  Thereafter, the CPU 84 first determines whether or not the random value set in step 508 is the jackpot random value “7” (S726). Here, if the random number value is “7” (S726: Yes), it is subsequently determined whether or not the deterrence flag for deterring the jackpot when the payout rate exceeds 3 is set (S728). . Here, when the suppression flag is not set (S728: No), after setting the special symbol jackpot flag (S730), a jackpot symbol such as 111,333 is selected (S732). Then, a reach mode is set as a mode at the time of stop (S737), and a special diagram variation timer for setting the variation time of the special symbol is started (S738).

  On the other hand, when the above-mentioned determination of jackpot (S726) is No, the jackpot random number value is “7”, but if the deterrence flag is set with the payout rate exceeding 3 (S728: Yes), the process proceeds to step 734, and after performing a detachment symbol selection process for selecting a detachment symbol such as 123 and 124, it is determined whether the selected detachment symbol is a reach symbol (S735). Then, when the outlier symbol is a reach symbol such as 114, 223 (S735: Yes), the process proceeds to step 737 and the reach mode is set. On the other hand, when it is not the reach symbol (S735: No), the process proceeds to step 736, and after stopping the symbol variation in the off mode, the special symbol variation timer is started (S738).

  When the symbol variation of the special symbol display device 34 is started in step 722 described above, in the determination of step 702 in the next machine cycle, it is determined whether the symbol variation is in progress, and the CPU 84 first proceeds to step 738 described above. It is determined whether or not the symbol variation timer set in this time has expired (S704). Here, until the symbol stop timer expires due to the passage of the variation time (S704: No), the variation of the symbol is continued (S716).

  When the symbol variation timer expires (S704: Yes), the CPU 84 stops symbol variation in each variation stop mode (S706). That is, when a normal loss that is not the reach mode is set, the 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, after determining whether or not the jackpot flag is set (S801: Yes), it is determined whether or not the winning prize opening is open (S802). Since the first winning action is not opened (S802: No). In step 804, it is determined whether it is an interval time after opening. In the first case, since it is a post-determination interval time determined to be a big hit (S804: No), the process proceeds to step 806, and it is determined whether R = 16. Here, R is the number of rounds and is incremented by 1 when passing a specific area after 1R ends. Since this is still R = 0 at this point (S806: No), the process proceeds to step 808, and the post-determination interval time timer is set. Determine if the time is up. Here, the post-determination interval time is the time from when the big hit is confirmed until the big winning opening is opened. When the set time is reached (S808: Yes), the process proceeds to step 810, where an instruction for a special prize opening command is issued, and the special prize opening is opened.

  In the next machine cycle, it is determined whether or not the special winning opening in step 802 is open. Since the special winning opening is now open (S802: Yes), the process proceeds to step 812. In step 812, it is determined whether the special winning opening opening time timer is up. Here, since the special 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 is terminated. On the other hand, when it passes (S816: Yes), it progresses to step 818 and it is judged whether R = 15. Here, since it is the first time to open the special winning opening (S818: No), the process proceeds to step 820 to determine whether the specific area SW is ON. In this step 820, if the game ball has passed through the specific area when winning the big 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 will be continued assuming that it has passed (step 820: Yes). Due to the passage, the specific area SW is turned on (S822). Next, it is determined whether the count number ≧ 9, that is, whether approximately 9 game balls have been won in the big winning opening. If the count reaches 9 due to the winning in the big winning opening (S824: Yes), the process proceeds to step 826, where an instruction for closing the big winning opening command is issued, and the big winning opening 51 is temporarily closed. Then, the process proceeds to step 828, and it is determined whether the specific area SW is in an 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 turned off. Subsequently, the process proceeds to step 832 and after resetting the number of counts won in the big prize opening, the process proceeds to step 834 where R = R + 1. As described above, R indicates the number of rounds opened. If the special winning opening is closed and the specific area SW is ON, it is counted as one time.

  In the next machine cycle, whether the interval time after release in step 804 is the interval time after release (S804: Yes), the process proceeds to step 846. When the interval time after the opening reaches the timer time up (step 846: Yes), the process proceeds to step 810, and the big prize opening is opened again.

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

  In the next machine cycle, since it is determined whether or not the big winning opening is open in step 802, the current state is that the final round has ended (S802: No), the process proceeds to step 804. Since it is determined in step 804 whether it is an interval time after opening, the current state is that the big hit ends and the end delay time is entered (S804: No), the process proceeds to step 806. Since it is determined at step 806 whether R = 16 at the present time, R = 16 (S806: Yes), the process proceeds to step 848 to determine whether the end delay time timer is up. If the time is not yet up (S848: No), the process is terminated. On the other hand, if the time is up (S848: Yes), the process proceeds to step 850, and after resetting R, the big hit flag is turned OFF (S852).

  In the pachinko machine according to the first embodiment, it is determined whether the ratio between the number of acquired balls and the number of shot balls exceeds a predetermined value, and a jackpot is not generated when it is determined that the ratio exceeds a predetermined value. . For this reason, it is possible to keep the payout rate below a predetermined value. In the first embodiment, one type of pachinko machine has been exemplified. However, in the case of three types of pachinko machines, when the hitting rate exceeds a predetermined value due to the occurrence of a hit with a normal symbol, the same kind of suppression is similarly performed. By setting a flag, it is possible to suppress the occurrence of hits and keep the payout rate below a predetermined value.

[Second Embodiment]
Next, 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 a high probability state with odd jackpot symbols such as 111, 333, 555, etc., and is generated with a probability of 1/330 in normal times. The next jackpot is generated with a probability of 1/110. On the other hand, jackpots that do not shift to a high probability are generated with even jackpot symbols such as 222, 444, and 666. Here, in the above-described first embodiment, when the payout rate exceeds 3, the occurrence of jackpot is suppressed. On the other hand, in 2nd Embodiment, when the payout rate exceeds 3, generation | occurrence | production of the jackpot which transfers 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 process and the special symbol variation process will be described. First, since the flow of the payout rate calculation process is the same as that of the first embodiment, the process will be described with reference to the flowchart shown in FIG.

  First, the number of fired balls per hour in the past is calculated (S902). Next, the number of acquired balls when the jackpot is generated at the present time is calculated (S904). This number of balls acquired is based on the average base corresponding to the model of the pachinko machine (average number of balls excluding the number of balls played per minute: 35 balls at low probability in this embodiment, and hits by normal symbols at high probability. It is calculated by adding the number of balls that accompany the jackpot to 100). The number of balls that accompany this jackpot is also the average number corresponding to the model (2400 in this embodiment). For example, if 30 minutes have elapsed since the game was started and the jackpot has been generated 4 times in the past 30 minutes, 2400 × 4 (times) +35 (times) × 30 minutes = 10650. Here, the number of balls when a jackpot that shifts to a high probability occurs is 15450, which is 10650 plus 4800 for two jackpots. That is, since the jackpot will be continued twice in a short period due to the shift to the high probability, 4800 pieces for two times are added as the expected number of acquisitions.

  Subsequently, a payout rate is calculated by dividing the number of acquisitions calculated in step 904 by the number of shots per hour calculated in step 902 (S906). Here, it is 15450 ÷ 6000, and 2.58 is obtained. Then, it is determined whether the calculated payout rate exceeds 3 (S908). Here, since the payout rate is 2.63 and does not exceed 3 (S908: No), the deterrence flag for deterring the occurrence of the jackpot of the probability change transition is turned off (S912).

  On the other hand, if 40 minutes (35 minutes in the low probability state and 5 minutes in the high probability state) have passed, if the jackpot has occurred 5 times in the past 40 minutes, 2400 x 5 (times) + 35 (pieces) × 35 (minute: low probability time) + 100 × 5 (minute: high probability time) = 13725. Furthermore, when the jackpot that shifts to a high probability occurs, the number of balls played is 18525, which is 16150 plus 4800 for two jackpots. For this reason, if the payout rate is calculated in step 906, 18525/6000 pieces and 3.09 is obtained. Here, since the payout rate exceeds 3.0 at 3.09 (S908: Yes), a suppression flag that suppresses the occurrence of jackpots that shift to a high probability is turned on (S910). In this embodiment, when calculating the payout rate in step 906, it is calculated by dividing by the number of fires for one hour (6000). For example, when calculating in 30 minutes, 30 minutes It is also possible to divide by the number of firings for 40 minutes when calculating by 40 minutes.

Next, the special symbol variation process of the second embodiment will be described with reference to FIG.
Here, the processing from step 702 to step 722 is the same as that of the first embodiment described above with reference to FIG.
In step 723, it is determined whether or not the extracted jackpot special random number value is a jackpot value. Here, in the low probability state, when “7” is set (probability 1/330) among 330 random numbers 0 to 329 shown in FIG. 12A (probability 1/330), it is assumed to be a predetermined value (S723: Yes), go to step 724 and set the special symbol jackpot flag. On the other hand, in the high probability state, when “7”, “107”, and “207” are set among 330 random numbers from 0 to 329 (probability 1/1100), it is assumed that the value is a predetermined value (S723: Yes), go to step 724 and set the 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 continues to determine whether the suppression flag is set (S726). Here, as described above, when the deterrence flag is set that the payout rate exceeds 3 due to the occurrence of a jackpot that shifts to a high probability (S726: Yes), the routine proceeds to step 732.

  On the other hand, when the suppression flag is not set (S726: No), the process proceeds to step 727 to determine whether or not to generate a jackpot that shifts to a high probability, as shown in FIG. Select one of. Then, it is determined whether the selected high-probability random number is 1 (S728), and in the case of 1 (S728: Yes), a high-probability flag for generating a jackpot to shift to 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 jackpot symbol is selected based on the high probability flag. That is, when the high probability flag is not set, an even number jackpot symbol of 000, 222, 444, 666, 888 is selected. On the other hand, when the high probability flag is set, odd jackpot symbols of 111, 333, 555, 777, and 999 are selected. The processing after step 736 is the same as that of the first embodiment described above with reference to FIG.

  In the embodiment here, after determining whether or not to shift to a high probability, the jackpot symbol is determined. Instead of this, for example, an odd number is a specified (probable change) symbol, an even number is a normal symbol, a jackpot symbol is determined, and at the same time, it is determined whether or not the probability is changed. The decision method of selecting one can be used.

Subsequently, a first modification of the pachinko machine according to the second embodiment will be described with reference to FIGS.
In the second embodiment described above, 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 modification, it is determined whether or not to shift to a high probability depending on the content of the determination symbol. In the first modification, as in the second embodiment described above, 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 symbol 31, a determination symbol display device 29 that displays a determination symbol of either ◯ or ×, a normal symbol display device 32 composed of three LEDs, and this normal symbol display device 32. A normal symbol memory 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 memory 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 variation processing described above with reference to FIG. Therefore, only the special symbol variation process will be described with reference to FIG.
Here, the processing from step 702 to step 722 is the same as that of the first embodiment described above with reference to FIG.
In step 723, it is determined whether or not the extracted jackpot special random number value is a jackpot value. Here, in the low probability state, when “7” is set out of 330 random numbers from 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 a special symbol jackpot flag. On the other hand, in the high probability state, when “7”, “107”, and “207” are set out of 330 random numbers from 0 to 329 (probability 1/110), the predetermined value is assumed (S723: Yes), go to step 724 and set the 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 processing in steps 732 to 706 is the same as that in the first embodiment described above with reference to FIG. The CPU 84 performs the determination symbol process of step 1000 following the process of step 706.

This determination symbol process will be described with reference to FIG. 16 showing a subroutine of the process.
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 change (S1004: No), change of the determination symbol is started (S1006). Then, it is determined whether the symbol variation time has elapsed (S1008). Here, when the fluctuation time elapses (S1008: Yes), when a jackpot that shifts to a high probability occurs, it is determined whether the deterrence flag that is set when the payout rate exceeds 3 is on (S1010).

  When the suppression flag is not set (S1010: No), it is determined whether the selected high probability random number is 1 (S1016). A high probability random number for determining whether or not to generate a jackpot that shifts to the high probability is set to 0, 1 shown in FIG. 12C in step S1014 of the special symbol starting process of the second embodiment shown in FIG. Either one is selected. When the high-probability random number is 1 (S1016: Yes), a high-probability flag for generating a jackpot that shifts to a high probability is set (S1018). On the other hand, when the suppression flag is set (S1010: Yes), the process proceeds to step 1012 and 0 is set as the high probability random number. Thereafter, the determination symbol corresponding to the high probability random number is displayed on the determination symbol display device 29. When generating a jackpot that shifts to a high probability, ○ is displayed, and when generating a jackpot that does not shift, × is displayed. In addition, the structure of the 1st modification of 2nd Embodiment mentioned above is applicable also to 2 type machines provided with the determination symbol.

  In the pachinko machine of the second embodiment, it is determined whether the ratio between the number of acquired balls and the number of shot balls exceeds a predetermined value, and when it is determined that the ratio exceeds a predetermined value, a hit to shift 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]
Next, 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 appearance rate is likely to exceed 3, the probability of jackpot per unit time is reduced by increasing the time of symbol variation of the special symbol display device, and the output rate is reduced. adjust. Here, when the payout rate does not exceed 3, the variation variation time is set to 5 seconds, and the symbol variation time is adjusted to 9 seconds on average. As a result, the maximum number of symbol fluctuations per minute is 6.7. Since there are cases where the winning frequency at the start opening is low and there is no change in the special symbol, and there are cases where the winning frequency is high and the variation continues, the average number of times the symbol varies is approximately six times. On the other hand, when the payout rate exceeds 3, the symbol variation time is adjusted to an average of 14 seconds by setting the variation fixing time to 10 seconds. As a result, the maximum number of symbol fluctuations per minute is 4.3, and the average number of symbol fluctuations is approximately four.

  That is, when the payout rate does not exceed 3, the average number of fluctuations per minute is 6 times, whereas when the payout rate exceeds 3, the average symbol change time per minute is 4 times. When the payout rate does not exceed 3, the probability of occurrence of jackpot per minute becomes 1.5 times. Thereby, in the pachinko machine of the third embodiment, adjustment of the payout rate is attempted.

  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 process and the special symbol variation process will be described. First, since the flow of the payout rate calculation process is the same as that of the first embodiment, the process will be described with reference to the flowchart shown in FIG.

  In the third embodiment, in the process of calculating the number of acquired balls in step 904, the number of acquired balls is a number obtained by adding 7200 equivalent to three jackpots to the counted number of prize balls. Thereby, it is prevented in advance that the payout rate exceeds 3.

The special symbol variation 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 that of the first embodiment described above with reference to FIG.
In step 738, it is determined whether or not a suppression flag is set. Here, when the suppression flag is set (S738: Yes), the long time is set as described above as the variation time of the special symbol variation device (S740). On the other hand, when the suppression flag is not set (S738: No), the short time is set as described above as the variation time of the special symbol variation device (S742).

  In the pachinko machine of the third embodiment, it is determined whether the ratio between the number of acquired balls and the number of shot balls exceeds a predetermined value, and when it is determined that the ratio exceeds a predetermined value, the special symbol variation time is increased. To do. For this reason, the number of hits per unit 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 likely to exceed 3, by changing the opening time of the big prize opening, the occurrence probability per unit time is reduced and the output 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. 23 (B), the 3 seconds opening of the special winning opening and the 2 seconds closing are repeated 10 times. However, if there are nine winnings during the opening for 30 seconds or opening and closing for 3 seconds as described above, the big winning opening is closed.

  In the fourth embodiment, in the calculation process of the number of acquired balls in step 904, a number obtained by adding 7200 equivalent to three jackpots to the counted number of prize balls is used as the acquired ball. Thereby, it is prevented in advance that the payout rate exceeds 3. In other words, when the payout rate exceeds 3, the number of symbol fluctuations per unit is reduced by opening and closing the big prize opening to increase the jackpot time. Thereby, in the pachinko machine of the fourth embodiment, adjustment of the payout rate per unit time is attempted.

  The processing of the CPU 84 in the pachinko machine of the fourth embodiment is the same except for the big prize opening control processing of the first embodiment described above with reference to FIG. For this reason, it demonstrates with reference to the flowchart shown in FIG. 18 which shows a special winning opening control process. Since the payout rate calculation process is the same as that in the third embodiment described above, description thereof is omitted.

  The processing from step 801 to step 811 is the same as that in the first embodiment described above with reference to FIG. In step 812, it is determined whether a suppression flag is set. Here, when the suppression flag is set (S812: Yes), it is determined whether it is the 3 second open interval described above with reference to FIG. 23B (S813). Then, during the 3 second opening interval (S813: Yes), the big prize opening is opened (S814), and for two seconds other than the interval (S813: No), the big winning opening is closed (S815). In S816 to S836, the description is omitted because it is the same as that in the first embodiment.

  In the pachinko machine of the fourth embodiment, it is determined whether the ratio between the number of acquired balls and the number of shot balls exceeds a predetermined value, and when it is determined that the ratio exceeds a predetermined value, the opening time of the big prize opening is set. 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 it is also possible to adjust the opening time of the special winning opening. In the above-described example, the configuration of the fourth embodiment is applied to one type of machine. However, the configuration of the fourth embodiment is applicable to three types of machine.

[Fifth Embodiment]
Subsequently, a pachinko machine according to a fifth embodiment of the present invention will be described. In the 1st-4th embodiment mentioned above, when the payout rate exceeded 3, the opening of the big winning opening by jackpot was adjusted. On the other hand, in the pachinko machine of the fifth embodiment, when the payout rate is less than 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, the normal symbol hit is generated with a probability of 1/10. On the other hand, when the payout rate falls below 1/3, the normal symbol hit is generated with a probability of 97/100, and the normal electric accessory is released. It is assumed that there is an average of 0.5 prizes in the ordinary electric accessory 42 for each ordinary symbol. If the fluctuation time of the normal symbol is 5 seconds and the opening time of the ordinary electric accessory is 1 second, the ordinary electric accessory is released 10 times per minute, and there is an average of 5 balls. If the number of prize balls is 6, 30 prize balls will be paid out by 6 × 5. For this reason, in a model with an average base as low as 20, even when a big hit does not occur for a long time, the payout rate does not become 1/3 or less.

  In the pachinko machine according to the fifth embodiment, the processing of the CPU 84 includes the payout rate calculation processing according to 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. It is the same except for. For this reason, it demonstrates with reference to the flowchart shown in FIG. 19 which shows the payout rate calculation process of 5th 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 acquired balls calculated in step 904 are applied to the following equation.
Number of acquired balls / number of fired balls <1.1 / 3
Number of shot balls-number of acquired balls> 7200

Here, two conditions are observed: the number of acquired balls is less than 1.1 / 3 of the number of shot balls, and the value obtained by subtracting the number of acquired balls from the number of shot balls is less than 7,200. The reason for attaching the second formula is to prevent it from being immediately below 1.1 / 3 when the store is opened and game balls are launched.

  In step 908, it is determined whether the payout rate is smaller than 1/3. 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 larger than 1/3 (S908: No), the payout flag is reset (S912).

  Next, with reference to FIG. 20, the normal symbol / normal electric combination control process in the pachinko machine according to the fifth embodiment will be described. In the fifth embodiment, in step 408 of the normal symbol starting process shown in FIG. 6, any one of 100 random numbers from 0 to 99 for determining whether or not the winning shown in FIG. Stored.

  The processing from step 602 to step 630 is the same as that in the first embodiment described above with reference to FIG. Step 631 determines whether or not the above-mentioned payout flag is set. Here, when the payout flag is not set (S631: No), it is determined whether the random number value is 90 to 99 (S633), and when it is 90 to 99 (S633: Yes), a win is generated (S640). . That is, a normal symbol hit 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 value is 3 to 99 (S632), and when it is 3 to 99 (S632: Yes), a win is generated (S640). That is, a normal symbol hit 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 acquired balls and the number of shot balls is less than a predetermined value, and when it is determined that the ratio is lower than the predetermined value, the winning rate is increased. For this reason, it is possible to keep the payout rate above a predetermined value.

  Subsequently, a pachinko machine according to a first modification of the fifth embodiment will be described. In the fifth embodiment described above, the probability of winning a normal symbol is improved in order to improve the payout rate. However, in this first modification, the payout rate is adjusted by adjusting the fluctuation time of the normal symbol. It has improved.

  Here, when the payout rate exceeds 1/3, the normal symbol variation time is set to 60 seconds. On the other hand, when the payout rate is less than 1/3, the fluctuation time of the normal symbol is set to 5 seconds. Here, if the normal symbol hit is generated with a probability of 97/100, the hit will almost certainly occur. If the fluctuation time is 60 seconds and the normal electric accessory is opened for 1 second, it will be about once per minute. If there is an average of 0.5 prizes in the ordinary electric accessory 42, there will be approximately 0.5 prizes per minute. On the other hand, if the normal symbol change time is 5 seconds when the payout rate is less than 1/3, if the release time of the normal electric accessory is 1 second, the normal electric accessory is released 10 times per minute. There is an average of 5 balls. If the number of prize balls is 6, 30 prize balls will be paid out by 6 × 5. For this reason, even if the average base is 20 and the model is not big hit, the payout rate is not reduced to 1/3 or less.

  Since the payout rate calculation process in the pachinko machine according to the first modification of the fifth embodiment is the same as the process described above with reference to FIG. 19, refer to FIG. 21 for the normal symbol / ordinary motor combination control process. To explain.

  The processing from step 602 to step 630 is the same as that in the first embodiment described above with reference to FIG. Step 631 determines whether or not the above-mentioned payout flag is set. Here, when the payout flag is not set (S631: No), the normal symbol variation time is set to 60 seconds (S632). On the other hand, when the payout flag is set (S631: Yes), the normal symbol variation time is set to 5 seconds (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 acquired balls and the number of shot balls is below a predetermined value, and when the ratio is determined to be below a predetermined value, Reduce the fluctuation time of. For this reason, the number of occurrences per unit time is increased, and the payout rate can be maintained at a predetermined value or more.

  Subsequently, a pachinko machine according to a second modification of the fifth embodiment will be described. In the fifth embodiment described above, the probability of winning a normal symbol is improved in order to improve the payout rate. However, in this second modified example, by adjusting the opening time of the normal electric accessory, The rate has improved.

  Here, when the payout rate exceeds 1/3, the opening time of the ordinary electric accessory is set to 0.2 seconds. On the other hand, when the payout rate is less than 1/3, the opening time of the ordinary electric accessory is set to 2 seconds. Here, if the normal symbol hit is generated with a probability of 97/100, the hit will almost certainly occur. When the payout rate exceeds 1/3, if the variation time is 8 seconds, it will be about 6 per minute. If there are 1 open of the normal electric combination and there is an average of 0.1 prizes during the release of the normal electric combination for 0.2 seconds, there will be about 0.6 wins per minute. On the other hand, when the payout rate is less than 1/3, the normal symbol fluctuation time is set to 8 seconds, and the normal electric accessory release time is set to 2 seconds. If an ordinary electric accessory is opened 5 times in one minute and there is an average of one prize during the opening of an ordinary electric accessory for 2 seconds, there will be an average of five balls in one minute. If the number of prize balls is 6, 30 prize balls will be paid out by 6 × 5. For this reason, even if the average base is 20 and the model does not generate a big hit for a long time, the payout rate is not reduced to 1/3 or less.

  Since the payout rate calculation process in the pachinko machine according to the first modification of the fifth embodiment is the same as the process described above with reference to FIG. 19, refer to FIG. 22 for the normal symbol / ordinary motor combination control process. To explain.

  The processing from step 602 to step 618 is the same as that of the first embodiment described above with reference to FIG. In step 620, it is determined whether the above-described payout flag 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 modification of the fifth embodiment, it is determined whether the ratio between the number of acquired balls and the number of shot balls is below a predetermined value, and when it is determined that the ratio is below the predetermined value, Increase the opening time of an accessory. For this reason, it is possible to keep the payout rate above a predetermined value.

  Subsequently, a pachinko machine according to a third modification of the fifth embodiment will be described. In the fifth embodiment described above, the probability of winning a normal symbol is improved in order to improve the payout rate, but in this third modified example, by increasing the probability of occurrence of a jackpot 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 a 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 a high probability state with a low probability (S727). On the other hand, when the payout flag is set (S726:
Yes), a high probability random number is extracted so as to generate a jackpot that shifts to a high probability state with high probability (S730).
