Description

  The present invention relates to a gaming machine that randomly changes a gaming state using a random number.

Conventionally, this type of gaming machine has a plurality of random number counters that perform a counting operation at a predetermined cycle, obtains a counter value counted by the random number counter at an arbitrary timing, and uses these counter values as random numbers The machine is known. Specifically, in a pachinko gaming machine as a conventional gaming machine, a first random number counter that continues to count M counter values in a loop at a predetermined period and N (M ≠ N) counter values at a predetermined period. And a second random number counter that keeps counting in a loop, and obtains both counter values by the first and second random number counters at the timing when the game ball wins a predetermined winning opening. Then, using both of the acquired counter values, whether or not to execute the winning game is determined, and a symbol displayed on the display means is determined (for example, refer to Patent Document 1).
JP 2004-173840 A ([0046], [0050], Table 1)

  By the way, the least common multiple (hereinafter referred to as the number of counts for one loop of the first random number counter (that is, “M” times) and the number of counts for one loop of the second random number counter (that is, “N” times). The counter values return to the initial state at the time when the counting operation of “one loop least common multiple count” is performed. While the counting operation of the one loop least common multiple count is being performed, the combination of both counter values by the first and second random number counters changes, and the change pattern is the one loop least common multiple count. Every time the count operation is performed, the same change pattern is repeated. That is, the first and second random number counters are synchronized with each other in a cycle in which the counting operation of the one loop least common multiple count is performed.

  For this reason, when the one-loop least common multiple count number is relatively small between the first and second random number counters, the first and second random number counters are synchronized in a relatively short period, and the randomness of the game is increased. Could be reduced. Then, there is a concern that the player finds the periodicity / regularity of the change in the gaming state and, for example, the game is executed intentionally by timing.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a gaming machine capable of ensuring the randomness of a game.

In order to achieve the above object, a gaming machine according to the invention of claim 1 includes a first random number counter that keeps counting a plurality of predetermined first counter values in a loop at a predetermined period, a second counter value of a plurality of defined, at predetermined intervals, first and a second random number counter to continue to count in a loop, the first random number counter and the second random number counter at any time was counted get the first counter value and the second counter value, in the gaming machine to be used for gaming control of their counter values as a random number, a random number counter selection means for selecting a first random number counter and the second random number counter alternately, A number-of-operations determination unit that determines any one operation number value from a plurality of predetermined different operation number values, and alternately selected by a random number counter selection unit The first random number counter or second random number counters has a characterized in that configured to perform the number of the count operation of the operation frequency value the count number determining means is point by point determined in accordance with the selection.

According to a second aspect of the invention, in the gaming machine of claim 1, a plurality of the first counter value, at a period different from the counting period of the first random number counter, a first associated counter to continue to count in a loop, A second auxiliary counter that continues to count a plurality of second counter values in a loop with a period different from the counting period of the second random number counter, and the first random number counter, the plurality of first counter values for one loop. The first initial value determining means that uses the first counter value counted by the first associated counter at the timing counted as the first counter initial value, and the second random number counter each loops a plurality of second counter values in one loop. And a second initial value determining means for setting the second counter value counted by the second associated counter at the timing counted by the second counter as the second counter initial value. A first counter value by one count loop portion of the next to the first counter initial value determined by the initial value determining means to the starting point, the second random number counter, the second counter initial value determined in the second initial value determining means This is characterized in that the first counter value is counted for the next one loop starting from.

[Invention of Claim 1]
According to the first aspect, the first random number counter or second random number counter selected alternately, by performing the count of the count operation of one by one determined operating frequency value with its selection, the The period during which the first random number counter and the second random number counter are not synchronized can be made longer than before, and the change pattern itself of the combination of both counter values becomes complicated and the randomness is increased. When they first random number counter and the second random number counter using first counter value has been counted and the second counter value to the control of the game as a random number acquired at an arbitrary timing, the gaming state It is possible to prevent the change from becoming periodic and regular, and to ensure the randomness of the game.

[Invention of claim 2 ]
According to the configuration of the second aspect , the first initial value determining means obtains the first counter value counted by the first associated counter at the timing when the first random number counter counts the first counter value for one loop. One counter is the initial value. Then, the first random number counter counts the first counter value for the next one loop starting from the first counter initial value, and thereafter repeats the same operation. Similarly, the second initial value determining means determines the second counter initial value, and the second random number counter counts the second counter value for the next one loop starting from the second counter initial value. repeat.

  Here, since the first associated counter performs a counting operation with a period different from the count period of the first random number counter, it is obtained from the first associated counter every time the first initial value determining means determines the first counter initial value. The first counter value to be sequentially becomes a different value. Similarly, every time the second initial value determining means determines the first counter initial value, the second counter value acquired from the second associated counter becomes a sequentially different value.

Thus, for each first random number counter and the second random number counter counts one loop component, the start point of the next one loop of the count changes cumbersome, conventionally, the first random number counter and the second random number counter The period of non-synchronization becomes longer, and the change pattern of the combination of both counter values itself becomes complicated. Therefore, when used for the control of the game first counter value acquired at an arbitrary timing and the second counter value as a random number, the random nature of the gaming state is ensured.

Hereinafter, an embodiment of a pachinko gaming machine to which the present invention is applied will be described with reference to FIGS. As shown in FIG. 1, the gaming board 11 of the pachinko gaming machine according to the present embodiment has a substantially circular gaming area YR surrounded by guide rails 12, and a display device 13 is provided at the center.

Both the movable wing pieces 14C, 14C are always in an upright state, and the opening width of the start winning opening 14 sandwiched between the two movable wing pieces 14C, 14C is large enough to accommodate about one game ball. ing. When the solenoid provided on the back of the game board 11 is driven due to the passage of the game ball to the gate switch 30, the movable wing pieces 14C and 14C are tilted sideways, and the game ball is guided to the movable wing piece 14C. As a result, the start winning opening 14 can be entered.

  When a game ball wins in the start winning opening 14, the start opening sensor 31 (see FIG. 3) provided in the start winning opening 14 detects the game ball, and the display device 13 will be described later based on the detection signal. Is displayed in a variable manner. In addition, while the display device 13 displays the symbols in a variable manner, up to four winning balls won in the start winning opening 14 are stored on hold.

The special winning opening 15 is formed in a horizontally long shape and is normally closed by the movable door 15T. Then, when a predetermined condition described later is satisfied, the pachinko gaming machine is in the “hit state” and the “ hit game” is executed. When the jackpot game is executed, the solenoid 15S (see FIG. 3) provided on the back of the game board 11 is driven, and the movable door 15T falls to the front side over a predetermined period. Thereby, the grand prize opening 15 is opened, and a large number of game balls can be awarded to the big prize opening 15 by using the movable door 15T as a guide. Here, when the movable door 15T is opened and closed, it is referred to as “round”. In one round, the opening time of the movable door 15T has reached 30 seconds, or When any of the 10 game balls has been won, the “big hit game” for one game is completed.

  A continuous winning opening and a counting winning opening are provided inside the big winning opening 15, and the continuous winning opening and the counting winning opening are opened. More specifically, when the movable door 15T is opened, the continuous winning opening is opened, and after winning the continuous winning opening, the solenoid 15M (see FIG. 3) is driven to close the continuous winning opening. The counting prize opening will remain open. Then, when the specific area sensor 32 (see FIG. 3) provided in the continuous winning opening detects the winning of the game ball, the right to continue is generated, and the above-described end condition (the opening time of the movable door 15T has reached 30 seconds). (Or 10 game balls won in the big winning opening 15) and the round is completed, the next round is continuously executed. When the count sensor 33 (see FIG. 3) provided in the counting prize opening detects the winning of the game ball, the winning balls to the big prize opening 15 are counted together with the winning balls to the continuous prize opening. As described above, it is checked whether or not a total of 10 has been reached.

The counter and the counter value selected by the operation counter selection value are hereinafter referred to as “operation target counter” and “operation target counter value”. Specifically, the jackpot counter value (label-TRND-A) and the jackpot symbol counter value (label-TRND-AZ1) are set to “0” when the power is turned on, and the main random number update process (S3) is executed. Then, as shown in FIG. 6, first, it is confirmed whether or not the operation end flag is ON (S321). If the operation end flag is ON (Yes at S321), the number of operations selected counter is incremented by 1 (S322), and the operation completion flag to OFF exits the processing (S3).

Operation completion flag is not ON (No at S321), confirms whether the number of operations selected flag is ON (S323), the number of operations from ON unless (No in S323) number of operations selection table (Table 3) The operation number value corresponding to the selection counter is acquired (S324 , corresponding to the “count number determination means” of the present invention ), and the operation number selection flag is turned ON (S325), and the process (S3) is exited.

  If the operation count selection flag is ON (Yes in S323), the operation count value is loaded (S326), and it is determined whether the operation count value is “0” (S327). If the operation count value is not “0” (No in S327), the operation target counter value is incremented by 1 to obtain an updated value of the operation target counter value (S328). It is determined whether or not the result incremented by 1 is equal to the upper limit value of each counter value (“630” for jackpot counter value, “10” for jackpot symbol counter value) (S329). Yes) The counter value is reset to “0” (S330), and if it is not equal to the upper limit value (No in S329), the update value of the counter value is not reset to “0”, and the process proceeds to the next process (S331).

  In step S331, the updated value of the operation target counter value is determined from the initial value of the operation target counter value set in steps S332, S125, and S135 described later (hereinafter referred to as “big hit counter initial value” or “big hit symbol counter initial value”). Subtraction is performed to determine whether it is “0” (S331). If it is “0” (Yes in S331), if the operation target counter is a jackpot counter, the current jackpot initial value counter value (label-TRND-AS) is acquired, and the jackpot counter initial value and jackpot counter value ( Label-TRND-A) (S332, corresponding to "first initial value determining means" of the present invention). If the operation target counter is a jackpot symbol counter, the current symbol initial value counter value (label-TRND-AZ1S) is acquired, and the jackpot symbol counter initial value and jackpot symbol counter value (label-TRND-AZ1) are acquired. (S332, corresponding to “second initial value determining means” of the present invention). Then, the operation count value is decremented by 1 (S333), and the process exits (S3). If the result of the subtraction in step 331 is not “0” (No in S331), the operation count value is decremented by 1 (S333), and the process (S3) is exited.

In step S327, if the operation count value is “0”, the operation count selection flag is turned OFF (S334), and the operation counter selection value is incremented by 1 (S335). As a result, it is determined whether the value of the operation counter selection value is “2” (S336). If it is “2” (Yes in S336), the operation end flag is turned ON (S337), and the operation counter selection value is set to “0”. Is stored in the RAM 51B (S338), and this process (S3) is exited. If the operation counter selection value is not “2” (No in S336), the operation number selection counter value is incremented by 1, and if the addition result is equal to the upper limit value (“6”), the counter value is reset to “0”. Then, this process (S3) is exited, and if it is not equal to the upper limit value, this process (S3) is immediately exited .

  As shown in FIG. 5, when the main random number update process (S3) is completed, the other random number update process (S5) is executed. In the other random number update process (S5), the counter values of the random number counters “label-TRND-RC, B1 to B3, T1, AS, AZ1S, F” are updated. These are also set to “0” when the power is turned on, and when other random number update processing (S5) is executed, first, as shown in FIG. 8, it is incremented by 1 (S521). As a result of incrementing by 1, it is sequentially checked whether or not the counter value is equal to the respective upper limit value (S522). If it is equal to the upper limit value, the counter value is reset to the lower limit value (S523) and this process (S5) is exited. If it is not equal to the upper limit value, the process exits (S5) without being reset to the lower limit value.

  When the operations in the main random number update process (S3) and other random number update processes (S5) are summarized, the operation target counter value (one of the jackpot counter value or the jackpot symbol counter value) is operated in accordance with the selection of the operation target counter. The first random number counter “Label-TRND-A” and the second random number counter “Label-TRND-AZ1” are synchronized by performing the counting operation for the number of times of the operation number value determined one by one from the number selection table (Table 3). The period during which the counter is not used can be made longer than before, and the change pattern itself of the combination of both counter values becomes complicated and the randomness can be improved.

  In the other random number update process (S5), the first associated counter “label-TRND-AS” and the second associated counter “label-TRND-AZ1S” are the first random number counter “label-TRND” in the main random number update process (S3). -A "and the second random number counter" Label-TRND-AZ1 "are counted repeatedly. Therefore, the jackpot initial value counter value (label-TRND-AS) and the symbol initial value counter value (label-TRND-AZ1S) are converted into the first random number counter “label-TRND-A” and the second random number counter “label- When used for updating TRND-AZ1, the jackpot counter initial value and the jackpot symbol counter initial value are different each time the value of the jackpot counter initial value or jackpot symbol counter initial value counts for one loop, and the combination of both counter values The change pattern itself becomes more complicated.

  When the other random number update process (S5) ends, an interrupt is permitted (S6), and a 4 ms timer interrupt process (S7) can be executed. The 4 ms timer interrupt process (S7) is repeatedly executed, for example, at a cycle of 4 msec when an interrupt pulse is input to the CPU 51A. During the remaining processing period from the end of the 4 ms timer interrupt process (S7) to the start of the next 4 ms timer interrupt process (S7) (the length of the remaining process period varies depending on the time required for the interrupt process). ), The update process of various counter values by the main random number update process (S3) and the other random number update process (S5) is repeatedly executed a plurality of times. Further, since the processing time required for the 4 ms interrupt processing (S7) varies depending on the processing contents, the number of executions of the main random number update processing (S3) and other random number update processing (S5) executed during the interrupt processing is also 4 ms. It varies depending on the processing time required for the interrupt processing (S7). If an interrupt pulse is input to the CPU 51A in the interrupt disabled state, the 4 ms timer interrupt process (S7) is not started immediately but is started after the interrupt is enabled (S6).

  The 4 ms timer interrupt process (S7) will be described. As shown in FIG. 8, in the 4 ms timer interrupt process (S7), an output process (S10) is first executed. In this process (S10), it is checked whether various commands determined in the special operation process (S17) described later and the counter value of the random number counter are set in the output buffer of the RAM 51B. Outputs the command and the counter value of the random number counter to various control boards 55, 56, 57, and 59 (see FIG. 3).

  In the input process (S11) performed subsequent to the output process (S10), a game using various sensors 30, 31, 32, 33 (see FIG. 3) provided in each of the winning openings 14, 15, 20 and the start gate 18, etc. A detection signal of a sphere is received.

  When the jackpot random number update interrupt process (S12) is executed subsequent to the input process (S11), the jackpot counter value (label-TRND-A) is incremented by 1 as shown in FIG. 10 (S121). It is checked whether or not the updated value of the counter value obtained as a result of incrementing by 1 is equal to the upper limit value “630” (S122). If it is equal to “630” (Yes in S122), the lower limit value “0” is determined. (S123), the process proceeds to the next process (S124). If it is not equal to “630” (No in S122), the process proceeds to the next process (S124) without being reset to “0”.

  In step S124, the updated value of the jackpot counter value (label-TRND-A) is subtracted from the initial value of the jackpot counter set in step S332 described above or step S125 described later to determine whether it is “0” (S124). If the subtracted value is not “0” (No in S124), the process exits (S12). If “0”, the current jackpot initial value counter value (label-TRND-AS) is acquired, and the acquired jackpot The initial value counter value (label-TRND-AS) is set as a jackpot counter initial value and a jackpot counter value (label-TRND-A) (S125).

  In the next symbol random number update interrupt process (S13), the jackpot symbol counter value (label-TRND-AZ1) is updated. As shown in FIG. 10, first, the jackpot symbol counter value (label-TRND-AZ1) is incremented by 1 (S131), and as a result of incrementing by 1, whether or not the updated value of the counter value is equal to the upper limit value “10” is determined. It is checked (S132). As a result, when the counter value is equal to “10” (Yes in S132), the lower limit value is reset to “0” (S133), and the process proceeds to the next process (S134), and is not equal to “10” (S132). No), the process proceeds to the next process (S134) without being reset to "0".

  In step S134, the update value of the jackpot symbol counter value (label-TRND-AZ1) is subtracted from the initial value of the jackpot symbol counter set in step S332 described above or step S135 described later to determine whether it is "0" (S134). . If the subtracted value is not “0” (No in S134), the process exits (S13), and if it is “0” (Yes in S134), the current symbol initial value counter value (label-TRND-AZ1S) is acquired. The acquired symbol initial value counter value (label-TRND-AZ1S) is set as a jackpot symbol counter initial value and a jackpot symbol counter value (label-TRND-AZ1) (S135).

  In the other random number update interrupt processing (S14) to be performed next, the counter value for reach determination ("TRND-RC"), counter values for left, middle and right special symbols ("TRND-B1 to B3" in Table 1 above). ”), The variation mode determination counter value (“ TRND-T1 ”), and the counter value per ordinary symbol (“ TRND-F ”) are updated. That is, as shown in FIG. 11, when other random number update interrupt processing (S14) is executed, first, it is incremented by 1 (S141). As a result of incrementing by 1, it is checked whether or not the counter value is equal to each upper limit value (S142). If it is equal to each upper limit value (Yes in S142), it is reset to each lower limit value (S143). If the process (S14) is exited and is not equal to each upper limit value (No in S142), the process (S14) is immediately exited.

  Summarizing the operations in the jackpot random number update interrupt process (S12), symbol random number update interrupt process (S13), and other random number update interrupt process (S14), in the jackpot random number update interrupt process (S12), in step S125 At the timing when the first random number counter “label-TRND-A” has counted the jackpot counter value (label-TRND-A) for one loop, the jackpot initial value counter value (label-TRND-AS) is Set as a value. Then, the first counter “label-TRND-A” counts the jackpot counter value (label-TRND-A) group for the next one loop with the initial value of the jackpot counter as a starting point, and thereafter repeats the same operation. Similarly, in the jackpot symbol determination random number update interrupt process (S13), in step S135, the jackpot symbol counter initial value is acquired, and the second random number counter “label-TRND-AZ1” The operation of counting the jackpot symbol counter value (label-TRND-AZ1) for the next one loop is repeated with the symbol counter initial value as the starting point.

  On the other hand, in the other random number update interrupt processing (S14), processing corresponding to steps S125 and S135 is not performed, and the operation of counting in a loop is repeated between the upper limit value and the lower limit value.

  The jackpot initial value counter value (label-TRND-AS) and the symbol initial value counter value (label-TRND-AZ1S) are updated only in the other random number update process (S5). It is not updated in the update interrupt process (S14). That is, the jackpot counter value (label-TRND-A) and the jackpot symbol counter value (label-TRND-AZ1) are the main random number update process (S3) of the main program PG1 of the main control board 50 and the 4 ms interrupt process (S7). Counter value is updated in the jackpot random number update interrupt process (S12) and symbol random number update interrupt process (S13), whereas the jackpot initial value counter value (label-TRND-AS) and symbol initial value counter value (Label-TRND-AZ1S) is updated only in the other random number update process (S5) of the main program PG1 of the main control board 50. For this reason, the first associated counter “label-TRND-AS” and the second associated counter “label-TRND-AZ1S” include the first random number counter “label-TRND-A” and the second random number counter “label-TRND”. -AZ1 "is counted at a different period.

  The start switch detection process (S15) performed next is shown in FIG. In this process (S15), the counter values of the various random number counters stored in the update areas R1 to R8 of the RAM 51B are taken out and stored in the address space corresponding to the reserved storage number. Specifically, first, it is checked whether or not a game ball has won the start winning opening 14, that is, whether or not a game ball has been detected by the detection sensor provided in the start winning opening 14 (S150).

  Here, when the game ball has not won the start winning opening 14 (no in S150), the process immediately exits (S15). When a game ball wins in the start winning opening 14 (yes in S150), it is checked whether or not the number of reserved memories has reached 4 (upper limit) (S151). If the number of reserved memories has reached four (yes in S151), the process immediately exits (S15) without storing a new counter value. On the other hand, if the number of reserved memories is less than 4 (no in S151), the number of reserved memories is incremented by 1 (S152), and various counter values are stored. Specifically, the jackpot counter value (label-TRND-A) stored in the update area R1 of the RAM 51B is read and stored in the address space corresponding to the number of reserved storages in the storage area R0 of the RAM 51B (S153). . Next, the jackpot symbol counter value (label-TRND-AZ1) stored in the update area R2 of the RAM 51B is read and stored in the address space corresponding to the number of reserved storages in the counter value storage area R11 (S154). .

  In the start switch detection process (S15), although not shown, the reach presence / absence determination counter value (label-TRND-RC) and the variation mode determination counter value (label-TRND-T1) are also updated in the update regions R3, R7. And stored in an address space corresponding to the number of reserved storages in the storage area R0. That is, the counter values of the various random number counters shown in Table 1 are acquired in response to the winning of the game ball at the start winning opening 14. The above is the description of the start switch detection process (S15).

  As shown in FIG. 8, the normal operation process (S16) is performed after the start switch detection process (S15). In this process (S16), when a normal symbol start sensor (not shown) provided in the start gate 18 detects the passage of the game ball, the counter value is acquired from the update area of the normal symbol determination counter value in the RAM 51B. And stored in the acquisition area provided in the RAM 51B.

  The special operation process (S17) performed after the normal operation process (S16) is performed based on the various counter values stored in the counter value storage area R11 of the RAM 51B in step S15.

  The special operation process (S17) is shown in FIG. 13. First, a special symbol creation process (S170) is performed. The outlier special symbol creation processing (S170) is shown in detail in FIG. 14. First, the addresses of the update areas R1 to R13 of the RAM 51B are set, and the left off symbol counter value (label-TRND-B1) is read out. (S100). Next, the off-right symbol counter value (label-TRND-B3) is read as the determination value (S101). The left off symbol counter value (label-TRND-B1) is compared with the right off symbol counter value (label-TRND-B3) (S102). This process (S170) is exited.

  If they do not match (no in S102), the address space of the stored symbol counter values (labels-TRND-B1, B2, B3) is stored in the counter value storage area R11 of the RAM 51B according to the number of reserved memories. The address space is set (S103), and the off symbol counter values (labels-TRND-B1, B2, B3) stored in the update areas R1 to R13 are transferred and stored in the set address space (S104). ).

  As shown in FIG. 13, the special action status is checked (S171, S173, S175) after the special special symbol creation process (S170), and the special symbol standby process (S172) and the special symbol change are performed according to the special action status. One of the process (S174), the special symbol confirmation process (S176), and the special electric accessory process (S177) is executed.

  When the special operation status is “1” (Yes in S171), that is, when the special symbols 13A, 13B, and 13C are not in a variable display or “big hit game”, the special symbol standby process (S172) ) Is executed.

  The special symbol standby process (S172) is shown in FIG. First, it is checked whether or not the number of reserved memories is “0” (S202). When the number of reserved memories is “0” (Yes in S202), that is, when there is no storage of various counter values acquired due to winning at the start winning opening 14, the display on the liquid crystal display unit 34 is displayed. It is checked whether it is a standby screen (S208). If the screen is a standby screen (yes in S208), the process immediately exits (S172). On the other hand, if the screen is not a standby screen (no in S208), a process for setting the standby screen (S209) is performed, and then this process is performed. Exit (S172).

  On the other hand, when the number of reserved memories is not “0” (no in S202), that is, when one or more of various counter values acquired due to winning at the start winning opening 14 are stored, Special symbol jackpot determination processing (S203), special symbol selection processing (S204), special symbol variation pattern creation processing (S205), special symbol random number shift processing (S206), and special symbol variation start setting (S207) to be described are performed. .

In the special symbol jackpot determination process (S203), whether or not the game is successful is determined, and it is determined whether or not the “jackpot game” can be executed. Specifically, as shown in FIG. 16, first, a jackpot counter value (label-TRND-A) stored in the counter value storage area R11 of the RAM 51B is read as a determination value (S310). Next, the address of the jackpot determination value table is set (S311), and as shown in Table 4 , for example, “1” to “19”, “397” are set as comparison values in the probability variation state, For example as a comparison value in the non-probability change state "3", "397" is Ru are set. Next, it is checked whether or not the probability variation state (the probability variation flag is ON) (S312). If the probability variation state is present (yes in S312), the jackpot counter value (label-TRND-A) is “1”. Based on whether or not it matches any one of “19” and “397”, it is determined whether or not it is a big hit (S315). On the other hand, if it is a non-stochastic fluctuation state (no in S312), whether or not the jackpot is based on whether or not the jackpot counter value (label-TRND-A) matches “3” or “397”. It is determined (S313). In any case, if it is determined that the game is a “hit” (Yes in S313, yes in S315), the jackpot flag stored in the RAM 51B is turned on (S314), and it is determined that it is not a “hit”. If this happens (no at S313, no at S315), do nothing (leave the jackpot flag off) and exit this process (S203). The above is the description of the special symbol jackpot determination process (S203) .

  As shown in FIG. 15, the special symbol selection process (S204) is executed after the special symbol jackpot determination process (S203). The special symbol selection process (S204) is shown in FIG. 17, and first, it is checked whether or not the jackpot flag is ON (S210).

When the jackpot flag is ON (Yes in S210), that is, when the acquired jackpot counter value (label-TRND-A) matches one of the hit values (see Table 4 ) in the jackpot determination value table The special symbols 13A, 13B, and 13C in the liquid crystal display unit 34 are all determined to be the same combination (grooves). Specifically, the jackpot symbol counter value (label-TRND-AZ1) acquired in the start switch detection process (S15) shown in FIG. 12 is set in the output buffer of the RAM 51B (S211), and the process (S204) is exited. .

On the other hand, if the jackpot flag is off (no in S210), that is, if the acquired jackpot counter value (label-TRND-A) does not match any of the hit numbers (see Table 4 ), 11 reach occurrence numerical values (for example, 5, 17, 28, 40, 51, 63) in which the reach presence / absence determination counter value (label-TRND-RC) acquired due to winning of the start winning opening 14 is preset. , 74, 86, 97, 109, 120) is checked (S212).

  If the acquired reach presence / absence determination counter value (label-TRND-RC) coincides with any of the reach occurrence values (yes in S212), the special symbols 13A, 13B, and 13C stop symbols become combinations that are out of reach. To do.

  Specifically, the counterclockwise symbol counter value (label-TRND-B1) stored in the counter value storage area R11 of the RAM 51B is forcibly changed to the same value as the counterclockwise symbol counter value (label-TRND-B3). (S213), and 1 is added to the left counter symbol counter value (label-TRND-B1) (S214), and the added value is forcibly set to the counter symbol counter value (label-TRND-B2) (S215). ). That is, the special symbols 13A, 13B, and 13C are determined so as to be displayed in a fixed stop manner, for example, “1 2 1” and “2 3 2”. Then, the determined off symbol counter values (labels-TRND-B1, B2, B3) are set in the output buffer of the RAM 51B, and the process (S204) is exited.

  On the other hand, when the acquired reach determination counter value (label-TRND-RC) does not coincide with any of the above reach generation values (no in S212), that is, when there is no reach, the counter of the RAM 51B The off symbol counter values (labels-TRND-B1, B2, B3) stored in the value storage area R11 are set as they are in the output buffer of the RAM 51B (S216), and this process (S204) is exited. The above is the description of the special symbol selection process (S204).

As shown in FIG. 15, after the special symbol selection process (S204), a special symbol variation pattern creation process (S205) is executed. The special symbol variation pattern creation process (S205) is shown in FIG. 18, and first, it is determined whether or not the jackpot flag is ON (S240). When the jackpot flag is ON (Yes in S240), that is, when the determination result is “Win”, based on the obtained variation mode determination counter value (label-TRND-T1), the following One of the fluctuation pattern 1 and the fluctuation pattern 2 is selected from the first fluctuation pattern table shown in Table 5 (S241). Specifically, when the acquired variation mode determination counter value is any value from 0 to 194, the variation pattern 1 is selected, and the acquired variation mode determination counter value is any of 195 to 198. If it is such a value, the variation pattern 2 is selected.

On the other hand, when the jackpot flag is OFF (no in S240), that is, when the determination result is “out”, based on the obtained variation mode determination counter value (label-TRND-T1), the following Any one of the fluctuation pattern 1, the fluctuation pattern 2 and the fluctuation pattern 3 is selected from the second fluctuation pattern table shown in Table 6 (S243). Specifically, when the acquired variation mode determination counter value (label-TRND-T1) is 0, the variation pattern 1 is selected and the acquired variation mode determination counter value (label-TRND-). When T1) is any value from 1 to 18, variation pattern 2 is selected, and the obtained variation mode determination counter value (label-TRND-T1) is any one of 19-198. If it is a value, the variation pattern 3 is selected.

  When the variation pattern is selected, other processing (S242) is performed, and then this processing (S205) is exited. In the other processing (S242), a variation pattern command corresponding to the selected variation pattern is set in the output buffer of the RAM 51B.

  As shown in FIG. 15, a special symbol random number shift process (S206) is performed after the special symbol variation pattern creation process (S205). This process (S206) is shown in FIG. 19, and first, the reserved storage number (the numerical value of the reserved number storage area of the RAM 51B) is decremented by 1 (S350). Next, the storage location of the various counter values in the counter value storage area R11 is shifted to the counter value storage area R11 on the lower level (address “0000” side in FIG. 4) (S351). Then, “0” is set in each address space of the highest-order counter value storage area R11 (S352), and the process exits (S206).

  As shown in FIG. 15, in the special symbol variation start setting (S207) performed after the special symbol random number shift process (S206), the special operation status is set to “2” and the variation start command is input to the output buffer of the RAM 51B. set. The above is the description of the special symbol standby process (S172) in the special operation process (S15).

As shown in FIG. 13, when the special operation status is “2” in the special operation process (S17) (no in S171, yes in S173), the special symbol variation process (S174) is executed. This process (S174) is shown in FIG. 20. First, change display times (Tables 5 and 6 ) according to the change pattern set in the special symbol change pattern creation process (S205, see FIG. 18). It is checked whether or not (see) has elapsed, and if it has not elapsed (no in S261), the process immediately exits this process (S174) and continues to display the variation of the special symbols 13A, 13B, and 13C.

  On the other hand, when the variation display of the special symbols 13A, 13B, and 13C is performed over the variation display time set according to the variation pattern (Yes in S261), the address of the variation stop table is set (S262). Then, the data storage process (S263) is performed. In these processes (S262, S263), a change stop command for stopping and displaying the special symbols 13A, 13B, and 13C during change display is set in the output buffer of the RAM 51B. Next, the special operation status is set to “3” (S264), and other processing (S265) is performed, and then this processing (S174) is exited.

  As shown in FIG. 13, when the special operation status is “3” in the special operation process (S17) (no in S173, yes in S175), the special symbol confirmation process (S176) is executed. The special symbol determination process (S176) is shown in FIG. 21, and it is first checked whether or not the big hit flag is ON (whether or not big hit) (S270).

  If the jackpot flag is not ON (No in S270), that is, if the determination result is “Out”, the special action status is set to “1” (S271), and this special symbol confirmation processing Exit from (S176). On the other hand, if the jackpot flag is ON (Yes in S270), that is, if the determination result is “Win”, the round counter for “Big Jack Game” is set (S272), and the special operation status is set to “ 4 ”(S273) and, for example, the release flag stored in the RAM 51B is switched from OFF to ON (S274), and the process goes out of the special symbol determination process (S176).

  Here, the round counter counts the number of “rounds” in the “big hit game”. In this embodiment, the initial value of the round counter is set to “15”.

  As shown in FIG. 13, when the special operation status is “4” in the special operation process (S17) (no in S175), that is, when the “big hit game” is being executed, the special electric accessory process ( S177) is performed. The special electric accessory processing (S177) is shown in FIG. 22, and first, the probability variation flag is switched from ON to OFF (S280). That is, when the “big hit game” is started, the probability variation state is forcibly ended.

  Next, it is checked whether or not the jackpot end flag is ON (S281). When the jackpot end flag is not ON (No in S281), that is, when the “hit game” is being executed, it is checked whether or not the jackpot 15 is being opened based on the release flag ( S282).

  When the special winning opening 15 is open (the open flag is ON) (Yes in S282), it is checked whether or not the round end condition is satisfied. Specifically, it is checked whether or not 10 game balls have been won in the grand prize opening 15 (S286) and whether or not the round end time (opening time of the big prize opening 15 is 30 seconds) has been reached (S287). The

  If the round end condition is not satisfied (both S286 and S287 are No), this process (S177) is immediately exited, whereas if the round end condition is satisfied (yes in either S286 or S287). The process at the end of the round (S289 to S293) is performed.

  That is, the excitation of the solenoid 15S is stopped by the special winning opening closing process (S289). Next, after decrementing the round counter by 1 (S290), it is checked whether or not the round counter has become “0” (S291). If the round counter is not “0” (no in S291), that is, If the “big hit game” has not been played up to the maximum round (15 rounds), the process immediately exits (S177). That is, even during the big hit game, when one round is completed, the open / close door 15T is in the “closed position”, and the big prize opening 15 is temporarily closed.

  On the other hand, when the round counter becomes “0” (Yes in S291), that is, when the jackpot game is played up to the maximum round (15 rounds), the jackpot end process (S292) is performed. Then, after the jackpot end flag is turned ON (S293), the process exits (S177).

  In step S282, when the big prize opening 15 is closed (open flag is OFF) (no in S282), it is checked whether or not it is time to open the big prize opening 15 (S283). Specifically, it is checked whether a predetermined waiting period after the “big hit game” is started or whether a predetermined interval period has elapsed since the end of the previous round. If the time has not elapsed (no in S283), the process exits (S177). On the other hand, if the waiting period or interval period has elapsed (yes in S283), a solenoid is performed by the big prize opening opening process (S285). 15S is excited. That is, when a predetermined time has elapsed since the start of the “big hit game” or the end of the previous round, the open / close door 15T moves from the “closed position” to the “open position” and the big prize opening 15 is opened.

  In step S281, if the jackpot end flag is ON (yes in S281), that is, if the jackpot game has been played up to the maximum round (15 rounds), the release flag, jackpot end flag, and jackpot flag are all By switching from ON to OFF (S294, S295, S296), it is checked whether or not the special symbols 13A, 13B, and 13C that are stopped and displayed are the probability variation symbols (odd tick) (S297). If it is not a probability variation symbol (no in S297), the probability variation flag remains OFF. On the other hand, if it is a probability variation symbol (yes in S297), the probability variation flag is switched from OFF to ON (S298) and then the special operation status. Is set to "1" (S299), and the process exits (S177). The above is the description of the special operation process (S17).

  As shown in FIG. 8, in the 4 ms timer interrupt process (S7), the reserved memory number process (S18) is performed after the special operation process (S17). This processing (S18) is shown in FIG. 23. The reserved memory number is read from the counter value group number stored in the RAM 51B (S180), and the data of the reserved memory number is set in the output buffer of the RAM 51B. (S181).

  This is the end of the description of the configuration of the pachinko gaming machine 10 according to the present embodiment. Next, functions and effects of the pachinko gaming machine 10 will be described.

  Simultaneously with the power-on of the pachinko machine 10, 4 ms interrupt processing (S7) is executed at a cycle of 4 ms, and each time the 4 ms interrupt processing (S7) is executed, each random number counter shown in Table 1 is incremented by 1 and the counter The value is updated.

  Now, when the player operates the operation knob 28 of the pachinko gaming machine 10 to drive a game ball into the game area YR, the game ball randomly flows down the game area YR. Then, when the game ball wins (enters) the start winning opening 14, the counter value of each random number counter is acquired as a random number value, and whether or not to execute the jackpot game according to the acquired counter value And the display content to be displayed on the display device 13 is determined.

  In this embodiment, the jackpot counter value (label-TRND-A), which is the counter value of the first random number counter “label-TRND-A” described above, is used to determine whether or not to execute the jackpot game. The jackpot symbol counter value (label-TRND-AZ1) which is the counter value of the second random number counter “label-TRND-AZ1” is used to determine the symbol for displaying the determination result on the display device 13. The Then, the first random number counter “label-TRND-A” and the second random number counter “label-TRND-AZ1” are alternately selected, and the counting operation is performed as the operation target counter.

  Then, the operation target counter performs a count operation for the number of operation frequency values composed of prime numbers that are selected one by one in accordance with the selection of the operation target counter. After performing the count operation for the operation frequency value, when the operation target is changed, the operation frequency value is selected again, the value for the operation frequency value is counted, and the operation is repeated thereafter.

  Each of the first and second random number counters “label-TRND-A, AZ1” is the next to each of the random number counters “label-TRND-A, AZ1” at the timing when the counting operation for one loop is completed. The initial value for counting for one loop, that is, the jackpot counter initial value and the jackpot symbol counter initial value are changed one by one.

  The first and second random counters “Label-TRND-A, AZ1” have the first and second associated counters “Label-TRND-AS, AZ1S” at the timing when the counting operation for one loop is completed. The count value that has been counted is used as an initial value for counting the next one loop by the first and second random number counters “label-TRND-A, AZ1”.

  The first associated counter “label-TRND-AS” is counted while the second random number counter “label-TRND-AZ1” is counted. Therefore, the first associated counter “label-TRND-AS” The count operation is performed at a cycle different from the count cycle of the first random number counter “label-TRND-A”. The first associated counter “label-TRND-AS” performs the counting operation only when the other random number update processing (S5) of the main program PG1 is executed, and does not perform the counting operation in the 4 ms interrupt processing (S7). Also from this, the first associated counter “label-TRND-AS” performs the counting operation with a period different from the counting period of the first random number counter “label-TRND-A”. Therefore, each time the count value of the first associated counter “label-TRND-AS” is used as the initial value of the first counter, the counter value provided by the first associated counter “label-TRND-AS” is sequentially changed to a different value. Become. Similarly, the second attendant counter “label-TRND-AZ1S” performs a counting operation at a period different from the count period of the second random number counter “label-TRND-AZ1”, and thus the second attendant counter “label-TRND”. Each time the count value of “−AZ1S” is used as the second counter initial value, the counter value provided by the second accompanying counter “label-TRND-AZ1S” sequentially becomes different values.

  Accordingly, the first and second random number counters count the number of operations of different prime numbers alternately, and the first and second random number counters “label-TRND-A, AZ1” count one loop. Each time the starting point of the count for the next one loop changes complicatedly, the period of time when the first and second counters “label-TRND-A, AZ1” are not synchronized becomes longer than before, and both counters The change pattern of the value combination itself becomes complicated. Therefore, when the counter values of the first and second counters “Label-TRND-A, AZ1” acquired at an arbitrary timing are used as random numbers for game control, the game state randomness is ensured.

The jackpot determination is performed when the jackpot counter value (label-TRND-A) matches the jackpot determination value (Table 4 ) as described above, and the jackpot symbol counter value (label-TRND-AZ1) “0” to The numerical value “9” is displayed on the display device 13 as a glance.

  Here, when the jackpot determination and the jackpot symbol are determined using only the first and second counter values (label-TRND-A, AZ1) without using the associated counter and adding prime numbers, Regularity can occur. For example, in the case of the first counter that counts from “0” to “629” and the second counter that counts from “0” to “9”, the first counter value matches the jackpot determination value “397” The second counter value at this time is always “7”. Even if the upper limit value of the first counter is set to “631” (the number of constituents of the first counter value is “632”, it is not a real number multiple of the constituent number of the second counter value “10”). The second counter value when it coincides with the judgment value “397” is “7” “9” “1” “3” “5”. Appears.

  If there is such a regularity in the symbol (number) when the jackpot is reached, it will be easier for the player to predict the symbol when the next jackpot and maintain the game's preference become unable. In particular, when the value of the jackpot symbol is an odd number, it becomes a so-called “probability” that the jackpot judgment is likely to occur again after the jackpot game is finished, so the player expects an odd number of eyes to be displayed. Will enjoy. The jackpot symbol has regularity, and as shown in the example above, if odd numbers continue, it will be extremely advantageous to the player. Conversely, if even numbers continue, it will be extremely disadvantageous. End up. In addition, the player knows this regularity, and predicts the next big hit and predicts the symbol, so that the game can be stopped or continued.

  However, in the present embodiment, the first and second counters (label-TRND-A, AZ1) can be confirmed by simulation in the following examples by alternately counting the number of operation times of different prime numbers. As described above, the regularity as described above is lost between the numerical values counted by the first and second counters. Furthermore, when each counter (label-TRND-A, AZ1) counts for one loop, the next count is started from the numerical value counted by another associated counter, and the continuity of each counter value is lost. As a result, odd numbers and even numbers do not continue in the numerical value of the jackpot symbol, making it impossible for the player to make a final decision using regularity. In addition, since the continuity and regularity of each counter value are lost, both counter values are not synchronized in a short cycle. As a result, the randomness of the jackpot symbol displayed at the time of the jackpot can be ensured, and the game preference can be stably maintained.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, a period in which a plurality of counter values for generating random numbers are not synchronized is longer than that in the past. Further, the change pattern itself of the combination of the counter values becomes complicated. Thus, when a plurality of counter values acquired at an arbitrary timing are used as random numbers for game control, the randomness of the gaming state is enhanced. And, when both counter values counted by the jackpot determination counter and the jackpot symbol determination counter are acquired at an arbitrary timing and used as random numbers for game control, the game state changes periodically and regularly. Can be prevented, and the randomness of the game can be secured.

  In the configuration of the above-described embodiment, the first and second random number counters “label-TRND-A, AZ1” are alternately counted for the number of primes without using the associated counters “label-TRND-AS, AZ1S”. Only by this, the simulation which changes the jackpot counter value (label-TRND-A) and the jackpot symbol counter value (label-TRND-AZ1) was performed. As a result, the jackpot symbol counter value (label-TRND-AZ1) when the jackpot counter value (label-TRND-A) that is a jackpot determination is “3”, the first loop of the first counter is “5”, The second loop is “7”, the third loop is “8”, the fourth loop is “1”, and when the jackpot counter value is “397”, the first loop “6”, the second loop “8”, the third loop Eye “6”, loop 4 “3”, and so on. As a result, it was confirmed that the randomness can be secured as described in the above embodiment.
