Description

The present invention relates to a pachinko gaming machine, and more particularly to a pachinko gaming machine that is in a jackpot state that is advantageous to a player when it is determined that a value extracted from a random number counter with a predetermined period is a jackpot value.

In a conventional pachinko machine, the random number counter is updated at a predetermined cycle on the main control board, and one value is extracted from the random number counter at the timing when the ball wins the starting winning opening, and the extracted value is compared with the determination table. A lottery process is performed so as to determine whether the game is a big hit or a lost game and win if the player wins.

For example, in a pachinko gaming machine with a winning probability of 1/300, the random number counter is updated in the range of 0 to 299 by a timer interrupt of a predetermined period, and rotates while changing the initial value. For example, if a timer interrupt occurs at intervals of 4 ms and the value of the random number counter is updated, one round is made in 1.2 seconds. If a plurality of balls win the start winning opening within 1.2 seconds, a plurality of values are extracted from the same period of the random number counter.

When a plurality of balls have won at the start winning opening at intervals of 1.2 seconds or more, the probability that the extracted value extracted from the random number counter at each winning timing is 1/300, respectively.

On the other hand, when a plurality of balls win the start winning opening within 1.2 seconds within the same period of the random number counter, the probability that the value extracted for the winning of the first ball is a big hit is 1/300. When the value extracted for the first ball winning is lost, the probability that the value extracted for the second ball winning is a big hit is 1/299, and further extracted for the second ball winning. The probability that the value extracted for the winning of the third ball is a big hit when it loses is also 1/298, and so on, and so on. In fact, if the pachinko machine is a type of pachinko machine in which the hold of the extracted value is reset after the jackpot is over, there is no need to consider the jackpot with the remaining extracted value. Expectation is up.

If multiple balls win at intervals of 1.2 seconds or more, each ball may be a big hit, whereas multiple balls win within 1.2 seconds Is likely to hit a jackpot on only one of the balls, in fact, the expected value for the jackpot does not change in either case.

However, if the number of lotteries with a high probability is limited, such as a pachinko game machine of a type that executes a high-probability lottery within a predetermined number of times after the jackpot ends (hereinafter referred to as an ST type), the limitation is anyway. As long as it can be extracted from the random number counter even if only one value can be extracted from the random number counter within the predetermined number of times, the expected value when lottery with multiple values extracted from the same period is not It becomes larger than the case.

Furthermore, if the holding of the extracted value is reset every time a jackpot is generated and the game is started from a state where the number of holdings is always zero after the jackpot ends, the possibility that the held extracted value is a jackpot Or if you win multiple times in the same cycle, if you win a big hit with the first ball, you do not need to consider that the rest are all lost, so it is more likely that you will win a big win if you win simultaneously Is clear.

The present invention has been made in view of such circumstances, and when a plurality of values are extracted from within the same period of the random number counter, the player is told that “the value is extracted from within the same period.

In the jackpot process, the main circuit 120 performs a process of continuing 15 rounds, with the round winning opening 13 being opened and 10 rounds being won or closing after 25 seconds.

Next, the operation of the pachinko gaming machine 1 according to the first embodiment configured as described above will be described with reference to FIGS.

After the power to the pachinko gaming machine 1 is turned on, the balls prepared in the ball supply tray 5 are launched toward the game board 3 by the launching device 110 including the handle 6. The ball that has reached the game board 3 flows down on the board surface of the game board 3.

When the ball flowing down on the board surface of the game board 3 passes through the passage gate 11, the gate passage detector 111 detects this and a passage detection signal is transmitted to the main circuit 120.

In the passage detection process, the main circuit 120 detects the passage of the ball of the passage gate 11 based on the passage detection signal (S101 in FIG. 7), and when the ball does not pass (S101: NO in FIG. 7), the ball Wait until passes.

When it is detected that the ball has passed through the passing gate 11 (S101 in FIG. 7: YES), the main circuit 120 extracts the value from the random number counter for ordinary use (S102 in FIG. 7), and extracts the ordinary figure. It is determined whether or not the number of values held is four, which is the maximum number of holds (S103 in FIG. 7). If the number of hold of the extraction value of the usual figure is four (S103 of FIG. 7: YES), the main circuit 120 ends the passage detection process. That is, the extracted value of the usual figure exceeding 4 which is the maximum holding number is discarded without holding.

If the number of hold of the extraction value of the usual figure is not four (S103 in FIG. 7: NO), the main circuit 120 stores the extraction value in the usual figure hold storage area on the RAM 123 and holds it (see FIG. 7). In step S104, a new map reservation LED on the map reservation number display unit 18 is turned on (S105 in FIG. 7), and the passage detection process is terminated.

If there is no hold of the extracted value in the usual hold storage area (S201 of FIG. 8: NO), the reading process of the usual figure hold is ended.

If there is a hold of the extracted value in the reserved map storage area on the RAM 123 (S201 of FIG. 8: YES), the main circuit 120 is displaying the fluctuation of the previous map in the map display unit 17. Is determined (S202 in FIG. 8).

If the previous normal map is being displayed (S202: YES in FIG. 8), the main circuit 120 ends the general map hold reading process.

If the previous usual display is not being displayed (S202: NO in FIG. 8), the main circuit 120 determines whether or not the second start winning opening 16 that is an electric chew is open (S203 in FIG. 8). ). If the second start winning opening 16 that is the electric Chu is being opened (S203 of FIG. 8: YES), the main circuit 120 ends the normal-pending reading process.

If the second start winning opening 16 that is the electric chew is not open (S203 of FIG. 8: NO), the main circuit 120 stores the oldest usual figure held in the reserved figure storage area on the RAM 123. The extracted value is read out (S204 in FIG. 8), one of the common figure hold LEDs on the common figure hold number display section 18 is turned off (S205 in FIG. 8), and the fluctuation process of the normal figure (see FIG. 13) is performed. Start.

In the usual fluctuation process, the main circuit 120 compares the extracted value read in the ordinary figure holding read process with the universal figure determination table (= 7) to determine a hit / miss (S301 in FIG. 9). .

Next, the main circuit 120 determines a normal variation time according to whether the probability change or the time is short or not (S302 in FIG. 9). For example, the variation time is determined as 1 second when the probability is changing or when the time is short, and 30 seconds when neither the probability is changing nor the time is short.

Subsequently, the main circuit 120 starts the fluctuation of the usual figure with the usual figure fluctuation LEDp1 of the usual figure display unit 17 (S303 in FIG. 9).

Next, if the determination result (lottery result) in step S301 is not a win (S304: NO in FIG. 9), the main circuit 120 lights the general map change LED p1 of the general map display unit 17 in orange (FIG. 9). S315), the usual fluctuation process is terminated.

If the determination result (lottery result) in step S301 is a win (S304 in FIG. 9: YES), the main circuit 120 lights the general map change LED p1 of the general map display unit 17 in green (S305 in FIG. 9). Then, the movable member 31 of the storage device 15 is swung to the lower discharge position (S306 in FIG. 9), and the second start winning opening 16 that is an electric chew is opened (S307 in FIG. 9). As a result, balls (up to five) stored in the storage device 15 are transmitted through the movable member 31 and try to flow into the second start winning opening 16 through the swinging blades 16a and 16a that are opened, and the swinging blade 16a. , 16a when the opening time is 5 seconds, most of the balls that have been stored win the second start winning opening 16.

Next, the main circuit 120 determines whether or not the probability change or the time is short (S308 in FIG. 9), and if it is during the probability change or the time short (S308: YES in FIG. 9), 5 seconds have passed. After waiting (S309 in FIG. 9), at the same time as closing the second start winning port 16 as an electric chew (S310 in FIG. 9), the movable member 31 is moved back to the upper storage position (S311 in FIG. 9). The usual variation process is terminated. As a result, the swinging blades 16a, 16a are closed, and the ball cannot be awarded to the second start winning port 16, and the ball is again stored in the storage device 15 by the backward movement of the movable member 31.

On the other hand, if it is not during the probability change or the time saving (S308: NO in FIG. 9), the main circuit 120 waits for 0.5 seconds to elapse (S312 in FIG. 9), and then the second start which is the electric Chu The winning opening 16 is closed (S313 in FIG. 9), and after waiting for 5 seconds from moving the movable member 31 to the lower discharge position (S314 in FIG. 9), the movable member 31 is moved upward. Returning to the storage position (S311 in FIG. 9), the usual fluctuation process is terminated.

When a ball wins the first start prize opening 12 or the second start prize opening 16, the first start prize detector 112 or the second start prize detector 113 detects this, and a prize detection signal is sent to the main circuit 120. Send.

The main circuit 120 detects the passage of the ball at the first start winning opening 12 or the second start winning opening 16 based on the winning detection signal (S401 in FIG. 10), and when the passage of the ball is not detected (FIG. 10 S401: NO), and waits until the ball passes.

When the passage of the ball is detected at the first start winning opening 12 or the second starting winning opening 16 (S401 in FIG. 10: YES), the main circuit 120 is normally set according to whether it is normal or when the probability is changed. A value is extracted from the random number counter for time or the random number counter for probability change (S402 in FIG. 10). The value at that time is extracted from the random counter for normal time or the random counter for probability change at the timing when the winning of the ball to the first start winning opening 12 or the second start winning opening 16 is detected. Alternatively, when a value is extracted from the same period of the random number counter for probability variation, the same value is not extracted.

Next, the main circuit 120 determines whether the number of special figure extraction values (the number of special figure extraction values held) held in the special figure holding storage area on the RAM 123 is four, which is the maximum holding number. It is determined whether or not (S403 in FIG. 10). If the number of reserved values of the special figure is four (S403 in FIG. 10: YES), the main circuit 120 instructs the payout device 108 to pay out a predetermined number of prize balls via the payout control board 107. (S410 in FIG. 10), the winning detection process is terminated. That is, the extracted value of the special figure exceeding the maximum holding number of 4 is discarded without holding.

If the number of reserved values of the special figure is not four (S403: NO in FIG. 10), the main circuit 120 stores the extracted value in the special figure holding storage area on the RAM 123 and holds it (see FIG. 10). In S404, it is determined whether or not the extracted value is within the same period as the previous extracted value and the normal time random number counter or the probability variation time random number counter (S405 in FIG. 10). This determination is performed in order to perform a display effect so that the player can know when a plurality of balls have won in the same period of the normal time random number counter or the probability variation time random number counter.

In the normal time random number counter and the probability variation time random number counter, a period counter that updates (+1) each time the value returns to 0 is provided, and the random number counter is provided when the value is extracted from each random number counter. If a value is also extracted from the cycle counter and both extracted values are stored together in the special-purpose hold storage area and held, the extracted values held before and after that will win in the same cycle. It is possible to determine whether or not the extracted value is extracted.

If the extracted value is not within the same period as the immediately preceding extracted value and the random number counter for normal time or the random number counter for probability variation (S405: NO in FIG. 10), the main circuit 120 The special figure hold LED is lit in orange (S411 in FIG. 10), instructs the payout device 108 to pay out a predetermined number of prize balls via the payout control board 107 (S410 in FIG. 10), and finishes the winning detection process. To do.

If the extracted value is extracted within the same period of the immediately preceding extracted value and the normal time random number counter or the probability variation time random number counter (S405 of FIG. 10: YES), the main circuit 120 displays the special figure pending number display. The new special figure hold LED of the unit 20 is lit in green (S406 in FIG. 10), and it is determined whether or not the number of special figure extraction values held in the special figure hold storage area on the RAM 123 is one ( S407 in FIG.

If the number of special figure extracted values held in the special figure hold storage area on the RAM 123 is one (S407 in FIG. 10: YES), the main circuit 120 sends a predetermined value to the payout device 108 via the payout control board 107. The payout of the number of prize balls is instructed (S410 in FIG. 10), and the winning detection process is terminated.

If the number of reserved special drawing values is not one (S407 in FIG. 10: NO), the main circuit 120 determines whether the color of the special figure holding LED that has been lit immediately before is orange (FIG. 10). S408).

If the color of the special figure hold LED that was lit immediately before is not orange (S408 in FIG. 10: NO), the main circuit 120 instructs the payout device 108 to pay out a predetermined number of prize balls via the payout control board 107. (S410 in FIG. 10), the winning detection process is terminated.

If the color of the special figure hold LED that was turned on immediately before is orange (S408 in FIG. 10: YES), the main circuit 120 lights the color of the special figure hold LED that was turned on immediately before in green (S409 in FIG. 10). Then, the payout device 108 is instructed to pay out a predetermined number of prize balls via the payout control board 107 (S410 in FIG. 10), and the winning detection process is terminated.

Next, in the special figure hold reading process, the main circuit 120 determines whether there is a hold of the extracted value of the special figure in the special figure hold storage area on the RAM 123 (S501 in FIG. 11). If there is no hold of the extracted value of the special figure in the special figure hold storage area (S501: NO in FIG. 11), the special figure hold reading process is terminated.

If there is a hold of the extracted value of the special figure in the special figure holding storage area on the RAM 123 (S501: YES in FIG. 11), the main circuit 120 displays the previous special figure in the special figure display unit 19 and the liquid crystal display unit 10. It is determined whether or not the variable display is being performed (S502 in FIG. 11). If the previous special figure is being displayed (S502: YES in FIG. 11), the main circuit 120 ends the special figure pending reading process.

If the previous special figure is not being displayed (S502: NO in FIG. 11), the main circuit 120 determines whether or not the jackpot is being hit (S503 in FIG. 11). If the jackpot is being hit (S503 in FIG. 11: YES), the main circuit 120 ends the special figure hold reading process.

If it is not a big hit (S503 in FIG. 11: NO), the main circuit 120 reads the extracted value of the oldest special figure from the special figure reserved storage area on the RAM 123 (S504 in FIG. 11), and the special figure pending number The special figure hold LED on the display unit 20 is turned on / off one by one (S505 in FIG. 11), and the special figure variation process (see FIG. 9) is started. The special figure hold LEDs q1 to q4 are lit in orange, green, or extinguished. When the oldest special figure extracted value is read, the special figure hold LEDs q2 to q4 are lit. By shifting the state to the special figure hold LEDs q1 to q3 and turning off the special figure hold LED q4, the lighting state of the special figure hold LED is shifted one by one.

In the special figure variation process, the main circuit 120 compares the extracted value of the special figure read out in the special figure hold reading process with the jackpot determination table (= 7) to determine the winning / losing (see FIG. 12 S601).

Now, assuming that the time is certain, the probability that five balls will be awarded separately at the first start winning opening 12 and the second starting winning opening 16 and a jackpot will occur with any of the balls is about 4/10. It becomes. Specifically, the probability of hitting with the first ball is 1/10, the probability of hitting with the second ball (probability of losing with the first ball and hitting with the second ball) is 9/10 × 1/10, and the probability of hitting with the third ball is (9/10) ² × 1/10 The probability of hitting with the ^fourth ball is (9/10) ³ × 1/10 The probability of hitting with the fifth ball is (9/10) ⁴ × 1/10, When these product sums are taken, it becomes 40951 / 100000≈4.1 / 10.

Further, at the time of probability change, the probability that five balls will win a person within 1.2 seconds (same period) at the first start winning opening 12 and the second starting winning opening 16, and the probability that a big hit will occur with any of the balls is: 1/2. Specifically, the probability of hitting with the first ball is 1/10, the probability of hitting with the second ball is 9/10 x 1/9 = 1/10 (losing with the first ball and hitting with the second ball), with the third ball The probability of winning is 9/10 × 8/9 × 1/8, the probability of hitting with the fourth ball is 9/10 × 8/9 × 7/8 × 1/7, the probability of hitting with the fifth ball is 9/10 × 8 Since / 9 × 7/8 × 6/7 × 1/6, the sum of these products is 5/10 = 1/2.

In this way, when multiple balls win in the same period of the random counter for normal time or the random number counter for probability variation, the probability that a big hit will occur with any of those balls is higher than when winning separately. Become. At the time of probability change, if the timing of winning the balls to the first start winning opening 12 and the second starting winning opening 16 is different, it will be played with the expectation that it will be a big hit with a probability of 1/10 each time. If five balls win a prize within 1.2 seconds in the absence of a ball, the probability that any one of these five balls is a big hit will be ½. Expectation is higher than (about 4/10).

Next, the main circuit 120 determines the variation time of the special figure and the contents of the effect to be displayed (whether character display or reach effect is present) based on the winning determination result (lottery result) (S602 in FIG. 12).

Subsequently, the main circuit 120 starts the symbol variation of the special symbol in the special symbol display unit 19 and the liquid crystal display unit 10 (S603 in FIG. 12). In the liquid crystal display unit 10, as illustrated in FIG. 2A, symbol variation is started from the state where the special figure is stopped, as illustrated in FIG. 2B. At the start of the special symbol design change, the liquid crystal display unit 10 may use a different background color or background image, or display a special character or character.

Next, the main circuit 120 determines whether or not the extracted value is an extracted value within the same period of the normal time random number counter or the probability variation time random number counter (S604 in FIG. 12). If there is (S604 in FIG. 12: YES), as illustrated in FIG. 2C, “Hot!” Or the like is superimposed on the liquid crystal display unit 10 (S605 in FIG. 12), and the extracted values within the same period are displayed. Otherwise (S604 in FIG. 12: NO), step S605 is skipped.

If the winning determination result (lottery result) is not a winning (S606 in FIG. 12: NO), the main circuit 120 stops displaying the lost symbol on the special-figure display unit 19 and the liquid crystal display unit 10 (S609 in FIG. 12). ), The special figure variation process is terminated. In the liquid crystal display unit 10, as illustrated in FIG. 2D, the left character stops, and as illustrated in FIG. 2E, the right character stops and illustrated in FIG. Then, the lost symbol is stopped and displayed.

If the winning determination result (lottery result) is a winning (S606 in FIG. 12: YES), the main circuit 120 stops and displays the winning symbol on the special figure display unit 19 and the liquid crystal display unit 10 (S607 in FIG. 12). The jackpot flag is turned ON (S608 in FIG. 12), and the special figure variation process is terminated.

Next, in the jackpot process, the main circuit 120 determines whether or not the jackpot flag is ON (S701 in FIG. 13). If the jackpot flag is not ON (S701 in FIG. 13), the jackpot process is terminated. To do.

If the jackpot flag is ON (S701 in FIG. 13: YES), the main circuit 120 determines whether the number of rounds is not 15 in order to open the jackpot 13 up to 15 times in one jackpot ( S702 in FIG.

If the number of rounds is not 15 (S702 in FIG. 13: YES), the main circuit 120 adds 1 to the number of rounds (S703 in FIG. 13), and excites the big prize solenoid 115 to open the big prize opening 13. It is opened (S706 in FIG. 13). Thereby, the winning of the ball to the big winning opening 13 becomes possible.

Either 10 balls are won in the big prize opening 13 (S705 in FIG. 13: YES) or 25 seconds have passed since the big prize opening 13 is opened (S706: YES in FIG. 13). Then, the main circuit 120 closes the big prize opening 13 by de-energizing the big prize solenoid 115 (S707 in FIG. 13), and ends the big hit process. As a result, it becomes impossible to win a ball in the special winning opening 13.

Thereafter, since the big hit flag is still ON (S701 in FIG. 13), the main circuit 120 repeats opening / closing of the big winning opening 13 (S701 to S707).

When the number of rounds reaches 15 (S702 of FIG. 13: NO), the main circuit 120 turns off the jackpot flag (S708 of FIG. 13) and resets the number of rounds to the initial value 0 (S709 of FIG. 13). The jackpot processing is finished.

According to the first embodiment, when a plurality of values are extracted from the same period of the normal time random number counter or the probability variation time random number counter, by appealing to the player that this lottery is hot, The player's interest can be further enhanced.

By the way, regarding the pachinko gaming machine 1 according to the first embodiment, the following modifications can be considered.

In the first embodiment, in the case of a jackpot, the pachinko gaming machine that resets all of the hold of the extracted value of the special figure at that time and starts from the state where the number of holds is 0 after the jackpot ends, Even a pachinko gaming machine that does not reset the hold after the end of the jackpot may be notified when a value is extracted from the same period of the random number counter. Expectation for jackpot is not actually changed compared to the case where values are extracted from different periods of the random number counter, but some players think that it will be easier to hit, so such an effect should be performed Can give an image that is likely to hit the player.

Further, in the first embodiment, the random number counter for extracting values according to the gaming state (normal state, probability variation state) at the time when the winning of the ball at the start winning opening is detected is the random number counter for normal time and the random number counter for probability variation time. However, the value may be always extracted from each of both random number counters. In this case, the determination means determines the extraction value to be determined as either the normal-time extraction value or the probability-variation extraction value according to the gaming state (normal state, probability variation state) at the time of determination. .
