Description

  The present invention relates to a gaming machine such as a pachinko machine, and in particular, in addition to a hit with a special game of a big hit that can be expected to be high, as well as suddenly without a big hit, from a low winning probability in normal times to a high probability The present invention relates to a gaming machine having a plurality of hit types including a so-called sudden hit of a sense of transition.

Conventionally, as described in Patent Document 1, the opening time of one round of big prize opening is 0.4 seconds, the prescribed number of rounds is 2 times, so that you can hardly expect the appearance, but the so-called winning hit probability is increased A sudden hit that suddenly shifts to probabilities is provided separately from the original high hits per ball, giving a novel gameplay. In this case, even if it hits a game state that has already become probable, it will not maintain the current status and there will be no disappointment, so it may be disappointing to the player. On the display device for deriving the lottery result, a detachment effect with super reach appears to make the impression that it is a big hit.

This unit 7 is a result of the success / failure based on the internal lottery random number (hereinafter referred to as the big lottery random number) R0, which is a special role to be acquired in the decorative frame 700 upon the start winning at the start ports 81 and 82 described below. Is provided with an effect display device 70 comprising a color liquid crystal display device for deriving the image through a predetermined moving image effect accompanied by variations in the upper symbol DA, the interrupted symbol DB, and the lower symbol DC. This effect display device 70 is consistent with the change display and stop display of a special symbol (hereinafter referred to as a special symbol) on a special symbol display device SD (hereinafter referred to as a special symbol display device SD) comprising an external 7-segment LED. Responsible for special figure game production. Each symbol DA, DB, DC is composed of eight kinds of main symbols 1 to 8 and a blank symbol br interposed between adjacent main symbols, and the main symbol of the upper symbol DA is 8, 7, 6, 5 , 4, 3, 2, 1, 8..., Middle design DB and lower design DC are 1, 2, 3, 4, 5, 6, 7, 8, 1. Scroll horizontally.

2) Upper start port 81, lower start port 82
For example, 3 prize balls are paid out per start prize by entering the upper start opening 81, and 4 prize balls are paid out per start prize by entering the lower start opening 82. For each starting winning prize within the upper limit of the holding ball, one big winning lottery random number R0 that is updated at a high speed within a range of 0 to 399, for example, is acquired and stored in the RAM of the main controller MC described later. In normal times under a low probability setting, winning in the internal winning lottery is a case where the acquired random number matches one big winning winning determination value, and the winning probability is 1/400. In a gaming state with a probability change under a high probability setting that can be entered depending on the type of jackpot, the jackpot winning determination value is increased to 10 and the winning probability is 10 times 40 times. The lower start port 82 is normally in a state where it is impossible to enter the ball by the upper start port 81, and the ball can enter when the petals 8a and 8b of the electric tulip 80 are opened.

3) Grand Prize Winner 9
At the time of the big hit game as a special game, the ball receiving member 90 covering the front is brought down to open the big winning opening 9. This release operation is repeated for a predetermined prescribed number of rounds, for example, with an interval of 2 seconds. The maximum winning opening that can be opened to the maximum per round is, for example, 28 seconds when the specified number of rounds is 15 rounds high, and extremely short when the specified number of rounds is 2 rounds. For example, 0.2 seconds. The maximum number of winnings allowed per round is, for example, nine. For example, 15 prize balls are paid out for each winning prize. Prior to the big hit game, a virtual effective line of any one of the left line w1, the middle line w2, the right line w3, the right descending line w4, and the right rising line w5 along the vertical direction on the effect display device 70. In addition, the triple of any one of the main symbols 1 to 8 is fixed and stopped when hitting a high ball, and a serial number such as “123” is fixed and stopped when hitting the lowest ball.

4) Gate GT
The gate GT starts a general game that starts with a change of a normal symbol (hereinafter referred to as a general diagram) on a normal symbol display device ND (hereinafter referred to as a general diagram display device ND) composed of 7 segment LEDs. By passing the ball to the gate GT, for example, a random number for normal lottery that is updated at a high speed within the range of 0 to 251 within the upper limit of, for example, four reserved balls is acquired and stored in the RAM of the main control unit MC. The winning probability of the regular drawing lottery is, for example, 250/252. After the normal map change for a predetermined time, for example 2.24 seconds, when the general map display device ND stops the “7” instead of “-” (a bar indicating a miss) and the winning is derived, the petal of the electric tulip 80 8a and 8b are opened in a predetermined manner. In a gaming state with support for increasing the lottery frequency of the internal winning lottery (hereinafter referred to as “lottery support”), for example, a 1.2-second opening is repeated four times over an interval of about 1 second, with lottery support. When there is no game state, release once for 0.2 seconds. It should be noted that the normal time fluctuation time may be shortened in a gaming state with a lottery support, or the winning probability of a general lottery may be reduced in a gaming state without a lottery support.

5) Others A predetermined number of, for example, 13 prize balls for each prize winning, for example, general winning holes 23 to 26, wind turbines 27a and 27b, ball stoppers 28, and a substantially circular game area 20 are partitioned and launched by the launch handle 4. Rail 21 for guiding a ball, ball return prevention piece 22, an out port 29 for discharging a ball that has missed a winning, and a special-purpose reserved ball display H1, which is turned on according to the number of random numbers R0 for lottery lottery that has not been passed From H2, H3, H4, the holding ball indicator h1, h2, h3, h4 for turning on the map according to the number of random numbers for drawing the drawing of unsuccessful results. A round number display RD, and game state lamps EP and ET which are turned on when a probability change and a lottery support are operated. Although not shown, the game area 20 has a number of game nails struck according to a unique gauge.

  FIG. 2 shows the control device CN of the gaming machine 1. A main control unit MC including a CPU, a ROM, and a RAM, and an effect control unit SC1 and a prize ball control unit SC2 on the sub-side. The main control unit MC includes a winning sensor 81s for the upper starting port 81, a winning sensor 82s for the lower starting port 82, a winning sensor 9s for the large winning port 9, a ball passing sensor GTs for the gate GT, and a general winning port 23 to 26. Sensors 23s to 26s are input. The effect control unit SC1 is input with the left, middle, and right buttons 3L, 3C, and 3R constituting the player operation switch 30.

  The ROM of the main control unit MC stores a game program Pg responsible for the main control of the game including the big win internal lottery, and the normal number of rounds is set to 2 rounds when the big win winning probability is under a low probability setting ( 2R) is a combination of a high probability setting for the minimum payout per ball and a 2R sudden hit, which is a minimum hit high accuracy hit, is distributed according to a normal allocation type, and a probability of winning a big hit When probability change under high probability setting, the distribution rate per 2R sudden accuracy is lower than normal, and according to the reduced amount, the distribution rate of hit type combined with high probability setting other than 2R sudden accuracy is normal The type distribution means Y per probability change time to be increased more than that is constructed. Also, the RAM of the main control unit MC has a special figure holding ball storage area K1 for storing the jackpot lottery random number R0 within the upper limit of the four reserved balls, and the ordinary drawing lottery random number within the upper limit of the four reserved balls. The general-purpose reserved ball storage area K2 and the like to be stored are secured.

  From the main control unit MC, a special figure display device SD, a general figure display device ND, a special-purpose reserved ball display H1 to H4, a special-purpose reserved ball display h1 to h4, a round number display RD, a game state lamp EP and ET are controlled, and a large winning opening opening / closing solenoid D1 for opening and closing the ball receiving member 90 of the large winning opening 9, and a lower starting opening opening / closing solenoid D2 for opening and closing the electric tulip petals 8a, 8b are controlled. ing. Further, an external terminal board OUT for taking out predetermined game information to the outside is connected.

  From the effect control unit SC1, the effect display device 70, the left and right speakers 51 and 52, and the lamps 61 to 69 are controlled. The ROM of the effect control unit SC1 stores an effect program Qg that receives a command transmitted one-way from the main control unit MC and is responsible for effect control according to the command. The prize ball control unit SC2 controls the prize ball payout device WS provided in the back mechanism inside the gaming machine.

  As shown in FIG. 3, in the game program Pg of the main control unit MC, when the power is turned on, the current RAM checksum value is compared with the checksum value saved during the previous power interruption process, and if they match, the game is effectively saved. RAM check processing for maintaining the current RAM content that has been generated and executing RAM initialization processing if there is a mismatch, and a random number update range in a random number generator built in the CPU that generates the random number R0 for jackpot lottery. Each of 0 is set in the initial setting of the hard random number, the special figure game flag indicating the progress step of the special figure game, and the timer interruption flag indicating whether or not the timer interruption executed at a fixed period of 4 ms, for example, has been executed. A flag initial setting process is performed (step S0).

  Subsequently, when the timer interrupt flag is not 0 and the timer interrupt has been executed (S1), the timer interrupt flag is set to 0 (S2), and the CPU watchdog timer is cleared (S3). Next, a special figure number lottery random value initial value counter R2 having an update range of 0 to 99, for example, for determining an initial value as a starting point for a round update of the special figure number lottery used for specifying the jackpot type is added by 1 ( If it exceeds 99, it is updated to 0 (S4), and timer interruption is permitted (S5).

  Under this timer interruption permission, for example, the random number counter R4 for variation pattern lottery having an update range of 0 to 2556 used for specifying the effect developed by the effect display device 70 is incremented by 1 (returned to 0 when 2556 is exceeded). In addition to updating, the random number counter R5 for the outreach lottery with an update range of 0 to 99, for example, which determines whether or not there is a reach effect in which two main symbols are gathered and the expectation for the big win is expected when the big hit is not won is plus 1 ( If it exceeds 99, it is reset to 0) and updated (S6). Thereafter, timer interruption is prohibited (S7).

  As long as there is no detection of a low voltage at which the main power supply voltage becomes equal to or lower than a predetermined value due to power-off or a power failure, the processing from step S1 is repeated (S11). When a low voltage is detected, the checksum value is written into the RAM, the RAM access is prohibited, the RAM content immediately before the power interruption is saved (S12), and the device enters a reset waiting state due to power-on and / or reset switch-on. The process is shifted (S13), and all the processes are completed. Even during power interruption, loss of RAM contents can be avoided by the backup power supply.

  As shown in FIG. 4, in the timer interrupt process, after all the registers built in the CPU are saved (S14), the special figure display device SD, the universal figure display device ND, the special figure holding ball indicators H1 to H4, LED display processing for controlling each display of the figure holding ball indicators h1 to h4, the round number indicator RD, and the game state lamps EP and ET is performed (S15).

  Subsequently, the special figure number lottery counter R1 having an update range of 0 to 99, for example, used for specifying the big hit type is incremented by 1 (when it exceeds 99, it is reset to 0, and once it returns to the initial value once, the counter R2 Initialize again with the value) and update (S16a), and determine the success or failure of the usual game, for example, increase the random number counter R3 for the usual drawing lottery having an update range of 0 to 251 (return to 0 when 251 is exceeded) (S16b), and the special figure number lottery random value initial value counter R2 is updated (S16c) as in step S4.

  Next, a timer counter subtraction process (S17) for decrementing the special figure timer for the special figure game and the special figure timer for the usual figure game by 1 (S17), and a prize based on the detection of each winning sensor 81s, 82s, 9s, 23s to 26s The ball command is set, and the big hit lottery random number R0, the special figure number lottery random number R1, and the variation pattern lottery are within the upper limit of the four reserved balls based on the start winning at the upper start port 81 or the lower start port 82 A random number R4 and a random number R5 for outreach lottery are sequentially stored in an empty address in the special figure holding ball storage area K1, and based on the passing of the ball at the gate GT, for the usual drawing within the upper limit of four holding balls. A game board surface sensor process is performed to store the random number R3 in an empty address of the usual reserved ball storage area K2 (S18).

  Subsequently, in the special figure display device SD, the common figure game processing (S19) for setting the operation of the electric tulip 80 attached to the lower start opening 82 according to the fluctuation of the common figure in the common figure display device ND and the success or failure of the common drawing lottery. Special figure game processing is performed for setting the special winning opening 9 according to the special figure fluctuation, the production setting on the production display device 70, and the success or failure of the jackpot (S20).

  Thereafter, a sub-command output for transmitting a production-related command to be set in the sub-transmission data buffer in the special game processing and a game state command to be set in the state command transmission buffer in the special game processing. Process (S21), a prize ball command output process (S22) for sending a prize ball command to be set in the prize ball transmission buffer in the game board surface sensor process to the prize ball control unit SC2, and a sub-number according to the number of random numbers for the big hit lottery A hold command output process for setting the hold ball related command in the transmission data buffer and transmitting it to the effect control unit SC1 is performed (S23).

  Next, a solenoid driving process (S24) for opening and closing the large winning opening opening / closing solenoid D1 and the lower starting opening opening / closing solenoid D2, signals such as starting winning, special figure confirmation display, universal figure confirmation display, big hit game, probable change, etc. After the external terminal board output processing (S25) which is output to the external terminal board OUT and is useful for information gathering in game lamps or hall computers, the timer interrupt flag is set to 1 (S26) and all registers are restored. (S27), return. Note that the timer interrupt process is designed so that its execution time is less than 4 ms at the longest.

  As shown in FIG. 5, in the special figure game process, only one specific subroutine corresponding to the special figure game flag is executed for each timer interruption process. Specifically, when the special figure game flag is 0, the special figure idling / hit determination process is performed (S28, 29), and when the special figure game flag is 1, the special figure number determination process is performed (S30, 31). Is 2 (S32, 33), the special figure game flag is 3 (S34, 35), and the special game flag is 4 Delay processing after fluctuation (S36, 37), if the special figure game flag is 5, the big hit start demonstration process (S38, 39), if the special figure game flag is 6, the big prize opening opening process (S40, 37) 41) When the special figure game flag is 7, round update processing is performed (S42, 43), and when the special figure game flag is 8, the big prize opening closing process is performed (S44, 45). If flag = 9) Exit demo process (S46) and each run, to return.

  As shown in FIG. 6, in the special figure idling / big hit determination process executed with the special figure game flag 0, if the big hit lottery random number storage number is 0 (S47), an idling command is set in the sub-transmission data buffer (S48). ), Return. If the jackpot lottery random number storage number is not 0, the number is decremented by 1 (S49), and the random number storage area for one start winning prize including the jackpot lottery random number R0 is pre-packed in the special figure holding ball storage area K1 (S50). ).

  Next, a probability variation flag is set that is set to 1 when the probability of winning the big hit is a high probability setting (S51), and in normal times when there is no probability variation, the table 1 that defines one value, for example, 11 is selected as the big hit winning judgment value. When the probability changes, the table 2 defining 10 values, for example, 11, 37, 59, 83, 107, 149, 167, 181, 199, 223, is selected as the jackpot winning determination value (S522). Subsequently, it is determined whether or not the value of the jackpot lottery random number R0 to be determined relating to the earliest acquisition matches the jackpot winning determination value (S53). If they match, the internal winning flag is set to 1 (S54). If there is a mismatch, the internal winning flag is set to 0 (S55), the special game flag is set to 1 (S56), and the process returns.

  As shown in FIG. 7, in the special figure number determination process executed with the special figure game flag 1, when the internal winning flag is not 1 (S57), the special figure number is set to 0 (S590). When the internal winning flag is 1, the special figure number lottery table 1 which is a normal time table defined by the type allocating means X is selected in the normal time when the probability variation flag is not 1 (S591). When the probability variation flag is 1 (S58), the special figure number lottery table 2 which is a probability variation table defined by the type distribution means Y per probability variation time is selected (S592), and the special figure number lottery counter R1 is selected. Based on, one of special figure numbers 1 to 5 is determined by lottery according to a predetermined distribution rate (S60).

  When special figure number 1 is selected, the number of rounds for repeatedly opening the special winning opening 9 is set to 15 rounds, and 15R probability variation is selected, which is a high probability of high output with 100 chance lottery support and special figure number 2 selection. When the number of rounds specified is 2 rounds, the 2R sudden hit is the minimum hit with high probability with probability variation. When special figure number 3 is selected, the round prescribed number is 15 rounds and low probability setting without probability variation is set. 15R normal hit, which is one of the high hits and low hits, when special figure number 4 is selected, the number of rounds is set to 15 rounds, and there is no change in accuracy, but with 50 lottery support as well 1R with support, which is one of the 2R support, when special figure number 5 is selected, the number of rounds is set to 2 rounds, and there is no chance of change, but it is the lowest payout with a lottery support until the next big hit. The per attached. After step S590 or S60, 2 is set in the special figure game flag (S61), and the process returns. The probability change will continue until the next big hit.

  As shown in FIG. 8, in the special figure variation pattern determination process executed by the special figure game flag 2, when the internal winning flag is 1 when the big hit is won (S62), the high figure of 15 rounds where the special figure number is not 2 or 5 In the case of winning (S63), the variation pattern lottery table TA1 is selected (S641), and in the case of two rounds with a special figure number of 2 or 5 (S63), the variation pattern lottery table TA2 is selected. (S642). The fluctuation time becomes longer in the order of normal reach, long reach, super reach 1, 2, 3, and 4, and the background moving image production that hits the expectation of the big hit becomes diverse. Per middle delay stop, after stopping the main symbols in the upper and lower stages, the middle stage stops with a slight delay and stops the serial number, and per sequential delay stop, stops at the time difference in the order of upper stage, lower stage, and middle stage. At the time of revival, after temporarily stopping the removal, it is changed again and the serial number is stopped.

  When the internal winning flag is not 0, a support flag in which 1 or 2 is set instead of 0 when lottery support is involved is determined (S65). If the threshold value for determining the presence / absence is set to 6 (S650) and the lottery support is not accompanied, if the special figure holding ball which is the remaining number of random numbers R0 for the big hit lottery in the special figure holding ball storage area K1 is 0 (S66), 36 is set to the threshold value (S660), and if there are one or two special figure holding balls (S67), 26 is set to the threshold value (S671). If there are 3 or more holding balls, 19 is set to the same threshold value (S672), and the value of random number counter R5 for outreach lottery is compared with the threshold value (S68). Accompanying fluctuation pattern lottery Select table TB1 (S691), selects the variation pattern lottery table TB2 with no reach demonstration ending in a relatively short period of time if not less than the threshold value (S692).

  Then, based on the value of the random number counter R4 for variation pattern lottery, one specific variation pattern is determined according to the distribution ratio in each table (S70), and specified according to the variation pattern number determined by the special figure timer. The special pattern fluctuation time is set (S71), the fluctuation pattern command specifying the fluctuation pattern number and the special figure number is set in the sub-transmission data buffer (S72), and the special figure game flag is set to 3 (S73). ), Return.

  As shown in FIG. 9, in the special-figure changing process executed by the special-figure game flag 3, the special-figure timer is not 0 and returns immediately without doing anything before the special-figure fluctuation time has elapsed (S74). Is zero and it is determined that the special figure fluctuation time has elapsed (S74), the delay time after the special figure fluctuation, for example, 125 corresponding to 0.5 seconds is set in the special figure timer (S75), and the sub-transmission data is set. The production stop command is set in the buffer (S76), the special game flag is set to 4 (S77), and the process returns.

  As shown in FIG. 10, in the post-figure fluctuation delay process executed by the special-figure game flag 4, the special-figure timer returns immediately if the special-figure timer is not 0 and before the post-figure fluctuation delay time elapses (S78). When it becomes 0 and it is determined that the delay time after the special figure change has elapsed (S78), the process branches according to the internal winning flag (S79).

  In other words, when the big win with the internal win flag is 1, if the special figure number is 15 rounds other than 2 or 5 (S80), the special figure timer shows 1675 corresponding to 6.7 seconds as the demonstration time until the big hit starts. Set (S81), and if the special figure number is 2 or 5 rounds, set 375 corresponding to 1.5 seconds as the demo time (S82), and set the jackpot start demo command in the sub-transmission data buffer (S83), set the special figure game flag to 5 (S84), and return.

  On the other hand, when the internal winning flag is not 0, if a limited number of lottery supports with a support flag of 1 are attached (S85), the remaining support counter is decremented by 1 (S86), and the value becomes 0 (S87), the support flag is set to 0 (S88), the support flag is set to the status command transmission buffer (S89), and a special game is executed as in the case of negative determination in step S85 and negative determination in step S87. The flag is set to 0 (S90) and the process returns.

  As shown in FIG. 11, in the big hit start demonstration process executed with the special figure game flag 5, the special figure timer is not 0 but returns immediately if the big hit start demo time has elapsed (S91), but the special figure timer becomes 0. When the elapse of the big hit start demonstration time is determined (S91), if the special figure number is 15 rounds other than 2 or 5 (S92), the special figure timer is set to 7000 corresponding to 28 seconds as the opening time of the big winning opening 9. Is set to 15 for the specified number of rounds (S931), and in the case of 2 rounds with the special figure number 2 or 5, 50 corresponding to 0.2 seconds as the opening time of the special winning opening 9 is set as the specified number of rounds. 2 is set (S932). Subsequently, 1 is set to the number of rounds (S94), 0 is set to the winning prize winning counter (S95), a round start command is set to the sub-transmission data buffer (S96), and 6 is set to the special game flag. Is set (S97) and the process returns.

  As shown in FIG. 12, in the special winning opening opening process executed by the special figure game flag 6, the number of winnings in the special winning opening 9 is 9 or more (S98), or the special figure timer is 0 and large. When the elapse of the winning opening is determined (S99), the effective time of the winning sensor from the closing of the large winning opening 9, for example, 450 corresponding to 1.8 seconds is set in the special timer (S100). A round end command specifying the current round number is set in the transmission data buffer (S101), the special game flag is set to 7 (S102), and the process returns.

  As shown in FIG. 13, in the round update process executed by the special game flag 7, if the special timer is not 0 but before the big prize winning sensor effective time elapses, it returns immediately (S103). When it becomes 0 and it is judged that the winning prize winning sensor effective time has elapsed (S103), the number of rounds is incremented by 1 (S104), and when the number of rounds exceeds the prescribed number of rounds (S105), the big hit game 1 is set in the end flag (S106), 0 is set in the big hit game end flag if it is less than the prescribed number of rounds (S107), and 50 corresponding to, for example, 0.2 seconds is set in the special figure timer as the closing time of the big prize opening. (S108). The interval time for closing the special winning opening 9 together with the effective time of the special winning prize winning sensor is 2 seconds. Subsequently, the special figure game flag is set to 8 (S109), and the process returns.

  As shown in FIG. 14, in the special winning game closing process executed by the special game flag 8, the special figure timer is not 0 and returns immediately before the special winning game closing time has elapsed (S110). When it becomes 0 and it is determined that the closing time of the big prize opening has elapsed (S110), the process branches according to the big hit game end flag (S111).

  That is, if the big hit game end flag is not 1 and before the specified number of rounds is exceeded (S111), if the special figure number is 15 rounds other than 2 or 5, 7000 corresponding to 28 seconds is set in the special figure timer (S112, 113). ) In the case of 2 rounds with the special figure number 2 or 5, 50 is set in the special figure timer (S112, 114), and 0 is set in the big prize winning prize counter (S115). A round start command specifying the current round number is set in the sub-transmission data buffer (S116), a special game flag is set to 6 (S117), and the process returns.

  On the other hand, when the big hit game end flag is 1 and the specified number of rounds is exhausted, if the special figure number is 15 rounds other than 2 or 5, the special figure timer is set to 6250 corresponding to 25 seconds as the big hit end demo time (S118). 119), if the special figure number is 2 or 5 rounds, 775 corresponding to 3.1 seconds is set in the special figure timer (S118, 120), and the jackpot end demonstration start command is set in the sub transmission data buffer. (S121), the special figure game flag is set to 9 (S122), and the process returns.

  As shown in FIG. 15, in the big hit end demo process executed by the special figure game flag 9, the special figure timer is not 0 but returns immediately before the big hit end demo time has elapsed (S123), but the special figure timer is set to 0. When it is determined that the jackpot end demo time has elapsed (S123), a probability variation flag, a support flag, and a remaining support counter are set according to the special figure number, that is, the jackpot type.

  That is, in the case of special figure number 1 15R probability variation, 1 is set in the probability variation flag, 1 is set in the support flag, and 100 is set in the remaining support counter (S124, 125). In this case, the probability variation flag is set to 1, the support flag is set to 0, and the remaining support counter is set to 0 (S126, 127). Set the support flag to 0 and the remaining support counter to 0 (S128, 129). If the support is 15R with special figure number 4, the probability variation flag is set to 0, the support flag is set to 1, and the remaining support is set. 50 is set in the number counter (S130, 131). In other cases, that is, with special figure number 5 with 2R support, the probability variation flag is set to 0 and the support flag is set. 2 indicating that the lottery support until the next big hit rather than the number continues to each set to zero support remaining number counter (S132). Subsequently, the probability change flag and the support flag are set in the state command transmission buffer (S133), the special game flag is set to 0 (S134), and the process returns.

  As shown in FIG. 16, in the subcommand output process of step S21, the sub-transmission data buffer is confirmed (S135), and if there is a command (S136), the effect-related command is transmitted to the effect control unit SC1 by the command transmission process. (S137), the sub transmission data buffer is cleared (S138). Subsequently, the state command transmission buffer is confirmed (S139). If the state command is present (S140), the state command is transmitted to the effect control unit SC1 (S141), the state command transmission buffer is cleared (S142), and the process returns. .

  As shown in FIG. 17, in the command reception process in the production program Qg in the production control unit SC1 on the sub side, the strobe signal indicating the data transmission request from the main control unit MC is an interrupt port of the CPU of the production control unit SC1. It is executed by inputting to. When a command reception interrupt occurs and an effect related command is received (T1), the process proceeds to effect branching processing (T2), and when a gaming state command is received (T3), the gaming state is stored in the RAM of the effect control unit SC1. (T4) An effect change process for changing the background, color, etc. on the effect display device 70 according to the gaming state is performed (T5).

  As shown in FIG. 18, in the effect branching process in step T2, a subroutine corresponding to the effect is executed. That is, the idling process is received at the time of receiving the idling command (T9, 10), the changing effect process is received at the receiving of the changing pattern command (T11, 12), the fixed symbol display process is received at the receiving of the stopping command (T13, 14), and the big hit When receiving the start demo command, the jackpot start demo process is performed (T15, 16), when receiving the round start command, the Nth round jackpot effect process is performed (T17, 18), and when the round end command is received, the inter-round effect process is performed (T19, 20) When the big hit end demonstration start command is received, the big hit end demo process is executed (T21, 22), and each is executed.

  FIG. 19 shows an example of an effect at the time of a normal game in which the jackpot winning probability is set to a low probability. When the effect control unit SC1 receives the change pattern command, the change effect process is started, and all the symbols DA, DB, DC of the upper, middle, and lower stages change on the effect display device 70. When the production stop command is received, all symbols are stopped by the fixed symbol display process. When off, neither the triple of the main symbols nor the serial number stops on any of the active lines w1 to w5. At the time of winning the big hit, if any of the 15R rounds, the triple of main symbols stops on one of the effective lines w1 to w5, and if any of the 2R rounds, on one of the effective lines w1 to w5 The main symbol sequence number stops.

  According to the distribution rate of each type of distribution means X per normal hour, 56% for 15R accuracy variation, 14% for 2R bump accuracy, 28% for 15R normal accuracy, 1% for 15R normal accuracy with support, 1R for 2R support accuracy Sorted with a probability of 1%. In 15R probability variation hit or 2R sudden probability hit, after the big hit, the probability change game with the big hit winning probability set to a high probability is entered. In addition, for 15R probability variation, lottery support by the electric tulip 80 is attached until 100 variation effects are performed, and for 15R normal support with support, the same lottery support is performed until 50 variation effects are performed. With support, the same lottery support will be provided until the next big hit.

  FIG. 20 shows an example of an effect at the probability variation game in which the jackpot winning probability is set to a high probability. When winning a big hit, according to the distribution rate of the specific distribution means Y per probability variation time, 69% for 15R probability variation, 1% for 2R sudden accuracy, 1% for 15R normal, 15% for 15R normal with support, 2R Each support hit is assigned with a probability of 14%. At 15R probability variation or 2R sudden probability, a high probability probability variation is maintained. In addition, the same lottery support is attached to 15R probability variation, 15R normal support with support, and 2R support with support.

  In the probability variation game, the allocation rate per 2R probability is lower than in the normal game, and instead, the allocation rate per 15R probability variation is high. As a result, it is possible to prevent as much as possible from pulling a probability change without a ball during the probability change. At the time of probability change, there is a high possibility that the probability change will continue after 15R probability variation hit. In addition, at the time of probability change, the distribution ratio per 2R support is also high, the disadvantageous hit that the probability change is suddenly released increases, and when a serial number is derived, a sense of tension runs and the game is sharpened.

  If it is 2R sudden hit, you can rest assured by maintaining the current situation, but if you have 2R support, you will be worried about damage caused by canceling probability change. However, lottery support will be provided until the next big hit, the start winning by opening the electric tulip 80 will be promoted, the winning lottery frequency will be increased, and there will also be a payout of the winning ball by the start winning, so in a good condition You can get a big hit lottery, and you can expect a recovery.

  Furthermore, at the time of probability change, the distribution ratio per 15R normal is 16% of the sum of 1% and 15%, which is lower than normal, and even if it is distributed per 15R normal, 50 lottery support is included. Since the ratio to the regular 15R with support is high, it is possible to reduce the situation in which the game is stopped immediately after acquiring a large number of balls, and it is possible to promote a continuous game.

Here, the probability α of changing from a low probability normal time to a high probability probability variation or not varying with a certain probability is 70% (= 0.7) of the total per 15R probability variation and 2R sudden accuracy, and the big hit under probability variation. The expected value P of the number of consecutive occurrences is P = log (1/2) / log (α) = 1.93, the normal time big hit winning probability ML is 1/400, the probability changing big hit winning probability MH is 1/40. The expected value M for jackpot is M = (P + 1) / (P / MH + 1 / ML) = 0.616161, and the expected number N of rounds is N = 15 × 0.85 + 2 × 0.15 = 13.05 , The number of winning prizes R per round is 9, and the number of winning balls S per prize is 15,
M × N × R × S = 10.8543, which is 12 or less, and also includes rules related to the wind management law.
Further, the rules related to the wind management law prohibit the fluctuation of the probability α and the expected value N during the game. However, according to the present embodiment, α = 0.7, 15R and 2R at both normal time and probability change. Since the distribution probability of special games is constant at 85:15, the probability α and the expected value N do not change. Therefore, implementation is possible without violating the above rules.

  As shown in FIG. 21, in the second embodiment, unlike the table of FIG. 7, in addition to the high appearance ball, the round prescribed number of rounds is 15R probability variation per 15R, per 15R normal, 15R normal per support, round The 6R probability variation per 6 rounds and the 6R normal per are added. For 15R probability variation, 6R probability variation, with support 15R normal variation, 50 lottery support is included. The distribution ratio per 2R sudden accuracy at the time of accuracy change is reduced to 1% compared to 19% at the normal time, and the accuracy per 15R accuracy variation and 6R accuracy variation are increased by 9% each. In addition, the per unit with 2R support is increased to 19% from the normal 1%, the per unit of 15R is lowered by 8%, and the per unit of 6R is reduced by 9%. % Lower.

  The normal big hit winning probability ML is set to 1/310, and the probable big hit winning probability MH is set to 1/31. In FIG. 8 step S63, FIG. 10 step S80, FIG. 11 step S92, FIG. 14 steps S112 and S118, “special figure number = 2 or 5?” Is read as “special figure number = 3 or 7?”. Apply.

  As shown in FIG. 22, instead of FIG. 15, a probability variation flag, a support flag, and a remaining support count are set for each of the seven jackpot types corresponding to the special figure numbers 1 to 7.

In FIG. 23, the example of the effect at the time of the normal game of Example 2 is shown.
In FIG. 24, the example of the effect at the time of probability change game of Example 2 is shown. This embodiment also has the same operation effect as described above. In Example 2, α = 0.7, P = 1.943, M = 0.00795, N = 15 × 0.6 + 6 × 0.2 + 2 × 0.2 = 10.6, R = 9, S = 15 And therefore
M × N × R × S = 10.7966, and rules related to the wind management law are also provided.
Further, the rules relating to the wind law prohibit the fluctuation of the probability α and the expected value N during the game, but according to this embodiment, α = 0.7, 15R, 6R and Since the distribution probability of 2R special games is constant at 60:20:20, the probability α and the expected value N do not vary. Therefore, implementation is possible without violating the above rules.

  As shown in FIG. 25, in the third embodiment, unlike the table of FIG. 7, the prescribed number of rounds is set to 2 rounds, the special winning opening opening time for each round is set to 28 seconds, and 15 prize balls × 9 counts × 2 rounds. = 270, 2R small ball probable variation with low probability and high probability per combination with high probability and lottery support combined with 100 lottery support per low ball that is expected to be small but less than 15R (Special figure number 3) is provided together with 15R probability variation (Special figure number 1), 2R bumps (Special figure number 2), and 15R normal hit (Special figure number 4).

  At the time of probability change, the distribution rate per 2R bump accuracy is reduced to 1% compared to 14% at the normal time, and the distribution rate per 2R small ball accuracy change is increased to 14% compared to the normal 1%. The normal jackpot winning probability is set to 1/400, and the probability-changing jackpot winning probability is set to 1/40. In FIG. 8 step S63, FIG. 10 step S80, FIG. 11 step S92, and FIG. 14 steps S112 and S118, “Special figure number = 2 or 5?” Means “Special figure number = 2 or 3?” “0.2 seconds (50)” in step S932 and FIG. 14 step S114 is “0.2 seconds (50) for special figure number 2 and 28 seconds (7000) for special figure number 3”. And apply each of the above.

  As shown in FIG. 26, instead of FIG. 15, the probability variation flag, the support flag, and the remaining support counter are set for each of the four jackpot types corresponding to the special figure numbers 1 to 4.
