Description of the Related Art Conventionally, there has been known a gaming machine that determines whether or not a gaming machine state is a jackpot gaming state, which is a gaming state advantageous for a player, when a game ball is won at a start opening. In this gaming machine, a jackpot random number is acquired due to the winning of the game ball to the starting port provided in the game board, and whether or not the jackpot random number is a predetermined random number determined in advance as a jackpot, A jackpot determination is made as to whether or not a jackpot gaming state is set. And if it is determined as a “hit” by this jackpot determination, a large number of game balls are paid out. In such a gaming machine, the gaming machine does not shift to the big hit gaming state unless the gaming ball wins the starting opening. Therefore, whether or not it is easy to win a game ball at the start port will affect the player's expectation.

  In view of this, a gaming machine having a plurality of start ports on one gaming board has been proposed (see, for example, Patent Document 1). This gaming machine is provided with two starting holes, and the jackpot determination is made regardless of which starting hole the game ball wins. Therefore, since it is possible to give the player an impression that the winning of the game ball is easier than a gaming machine having only one start port, the player's expectation is enhanced.

In addition, a gaming machine provided with a plurality of jackpot random number storage means having at least one storage area for storing jackpot random numbers has been proposed in a gaming machine having a plurality of start ports. According to this gaming machine, each starting port is associated with one of a plurality of jackpot random number storage means, and the jackpot random number acquired by winning the game ball is a jackpot random number corresponding to the winning starting port. The data are sequentially stored in the storage area of the storage means.

  According to the gaming machine of claim 1, the game machine has at least one storage area, and is provided with a plurality of jackpot random number storage means for sequentially storing jackpot random numbers in the storage area, and the game board wins a game ball. It has multiple mouths. Each winning opening is associated with one of the jackpot random number storage means in advance, and the jackpot random number acquired by winning the game ball at the winning opening is stored in the storage area of the jackpot random number storage means corresponding to the winning opening. The jackpot determination is performed based on the stored jackpot random number. Then, depending on which jackpot random number storage means stores the jackpot random number that triggers the variation of the symbol, it is the probability determined to cause a probability variation state in which the probability of being determined to be a jackpot is higher than the normal state Probability variation state rush rate, when the variation time of the symbol is shortened than the normal state is the probability that it will be determined that a short gaming state will occur, this is the short game state rush rate, the number of times the opening / closing member of the variable prize opening is opened At least one of the round number selection probabilities, which is the probability of selecting the number of rounds, is different. Therefore, since the value given to the player differs depending on which jackpot random number storage means stores the jackpot random number, that is, to which winning opening the game ball has won, which winning slot the gaming ball will win It is possible to entertain and entertain the game.

  In addition to the effect of the invention according to claim 1, the gaming machine according to claim 2 of the present invention has the number of jackpot random numbers that can be stored for each jackpot random number storage means, the number of so-called reserved balls. Since the upper limit of the game is different, it is possible to adjust the frequency at which the jackpot determination is performed by making a difference in the upper limit of the number of held balls according to the frequency at which the jackpot random number is stored, the difficulty of winning the game ball, etc. . Furthermore, by changing the value given to the player for each jackpot random number storage means in accordance with the difference in the frequency at which the jackpot determination is performed, it is possible to diversify the game contents and attract the player's interest.

  In addition to the effect of the invention according to claim 1, the gaming machine according to claim 3 of the present invention has a different upper limit of the number of reserved balls that can be stored for each jackpot random number storage means, and the smaller the upper limit, At least one of the probability variation state entry rate, the short-time gaming state entry rate, and the average value of the number of rounds selected is increased. The smaller the upper limit of the number of reserved balls that can be stored, the less frequent the jackpot determination is made. On the other hand, the value given to the player increases if the jackpot is reached, so the upper limit of the number of stored balls that can be stored is small The expectation that the player has increases, and the game can be enjoyed with interest.

  Further, in the gaming machine according to claim 4 of the present invention, in addition to the effect of the invention according to any one of claims 1 to 3, the frequency at which the jackpot random number is stored is different for each jackpot random number storage means. Since a plurality of winning holes are arranged, the value given to the player can be changed in accordance with the difference in the frequency at which the jackpot random numbers are stored. Therefore, the player can enjoy the game while being interested in which winning opening the game ball will win.

  Further, in the gaming machine according to claim 5 of the present invention, in addition to the effect of the invention according to any one of claims 1 to 3, the frequency at which the jackpot random number is stored is different for each jackpot random number storage means, The lower the frequency at which the jackpot random numbers are stored, that is, the higher the difficulty for storing the jackpot random numbers, the higher the probability variation state entry rate, the short-time gaming state entry rate, and the average value of the number of rounds selected. At least one is higher. Accordingly, the player can play the game while having fun because the greater the difficulty level for storing the jackpot random number, the greater the expectation for the results of the various determinations.

  In addition to the effect of the invention according to any one of claims 1 to 5, the gaming machine according to claim 6 of the present invention determines whether or not each jackpot random number is a random number determined in advance as a jackpot. For each jackpot random number determined to be a jackpot, whether it is a random number that causes a probability variation state, whether it is a random number that causes a short-time gaming state, and the number of rounds to any value Since a determination table storage unit that stores a table for determining at least one of the random numbers to be determined is provided, a random number for determining whether or not a big hit, a random number for performing various other determinations, Need not be acquired separately, and a plurality of determinations can be made by acquiring one random number. Therefore, the control is simpler than when a plurality of random numbers are acquired, and the burden on the gaming machine is reduced.

  In addition to the effects of the invention according to any one of claims 1 to 6, the gaming machine according to claim 7 of the present invention has the same number of winning holes and the number of jackpot random number storage means, and each of them is 1 Since the correspondence is made on a one-to-one basis, the value given to the player when it is determined to be a big hit differs depending on which winning opening the game ball has won. Therefore, the content of the game becomes simpler than the case where a plurality of winning prize openings correspond to one jackpot random number storage means.

  The gaming machine according to claim 8 of the present invention has a time-short game state determination means for determining whether or not to generate a time-short game state in addition to the effect of the invention according to any one of claims 1 to 7. And a probability variation state success / failure determination means for determining whether or not to generate a probability variation state, so by performing the determination of whether or not the short-time gaming state and the probability variation state are determined separately, the probability variation / Four gaming states can be generated: “time-short state”, “probability variation / non-time-short state”, “non-probability variation / time-short state”, and “non-probability variation / non-time-short state”. Therefore, the game content can be diversified as compared with the gaming machine that always causes the short-time gaming state simultaneously with the probability variation state, and the player's interest can be attracted.

  In addition, in the gaming machine according to claim 9 of the present invention, in addition to the effect of the invention according to any one of claims 1 to 8, which jackpot random number storage means stores the jackpot random number that triggers the variation of the symbol. Depending on the situation, it is possible to change the time-short gaming state entry rate, which is a probability that it is determined that the time-short gaming state is caused when the symbol variation time is shorter than the normal state. During the short-time gaming state, the variation time of the symbol is shortened compared to the normal state, and the number of jackpot determinations made per unit time is increased. Therefore, the player is more advantageous than the normal state. Therefore, since the value given to the player differs depending on which winning opening the game ball has won, it is possible to entertain the game by making the player interested in which winning opening the game ball will win.

Further, the RAM 52 is provided with various storage areas not shown.

  Next, each counter stored in the counter storage area 5201 of the RAM 52 will be described. The counter storage area 5201 includes a normal hit determination counter, a jackpot determination counter, a hit special symbol creation counter, an extra special symbol creation counter, a variation pattern determination counter, a special symbol variation time counter, a special symbol stop time counter, and a jackpot start screen display time. Each counter is stored.

  Note that the values of the normal hit determination counter, the big hit determination counter, the hit special symbol creation counter, the lost special symbol creation counter, and the fluctuation pattern determination counter are based on the interrupt signal from the interrupt signal generation circuit 57 (see FIG. 4). In the counter update process (S12, see FIG. 11) of the main process performed by the control program of the pachinko machine 1 to be executed, a predetermined amount (for example, 2 ms, which is an interrupt signal generation interval) (for example, an interrupt signal generation interval) , “1”). Each counter is provided with a minimum value (lower limit value) and a maximum value (upper limit value), and is configured to circulate within a numerical value ranging from the minimum value to the maximum value. In other words, if the counter value becomes the same as the maximum value as a result of the update, the counter value takes the minimum value in the next update. These values are used in normal symbol processing, special symbol processing, and the like performed in the main processing (see FIG. 11) to be described later, and the normal hit relation information storage area 5203, the first big hit relation information storage area 5205, and the second big hit It is stored in the relationship information storage area 5206 or the like.

  The special symbol variation time counter, the special symbol stop time counter, and the jackpot start screen display time counter are used as timer counters for measuring the elapsed time, and a predetermined amount (see FIG. 11, S12). For example, “1”) is subtracted.

  Hereinafter, each counter will be described in detail. The value of the normal hit determination counter is used to determine the normal hit determination. The normal hit determination is performed in response to a winning of a game ball to the normal symbol start gates 12a and 12b. When it is determined that the normal hit is made, the opening / closing members of the left and right second ordinary electric accessories 13a, 13b are opened for a predetermined time (for example, 0.5 seconds). The maximum value of the normal hit determination counter is “255”, the minimum value is “0”, “1” is added every interrupt (every 2 ms), and when it becomes “256” or more, it returns to “0”. . Then, in the main process (see FIG. 11), the value of the normal hit determination counter is read as “normal hit random number” and stored in the normal hit random number column of the normal hit relation information storage area 5203. In the present embodiment, the normal winning random number is “64” to “255”, and the normal winning random number is “0” to “63”.

  The value of the jackpot determination counter is used to determine the first jackpot and the second jackpot. The maximum value of the big hit determination counter is “301139”, the minimum value is “0”, “1” is added every interrupt (every 2 ms), and when it becomes “301140” or more, it returns to “0”. Then, in the main process (see FIG. 11), the value of the jackpot determination counter is read as “big jackpot random number”, and the jackpot random number column (see FIG. 7) of the first jackpot relation information storage area 5205 described later, or the second It is stored in the jackpot random number column (see FIG. 8) in the jackpot relation information storage area 5206. In the first jackpot determination, the first determination table stored in the first determination table storage area 5306 of the ROM 53 is the second determination table stored in the second determination table storage area 5307 in the second jackpot determination. The jackpot determination is performed based on whether or not the stored jackpot random number is a value set in advance as a jackpot, and details thereof will be described later with reference to FIGS. 9 and 10.

  In addition, when the pachinko machine 1 is started, “0” is stored in the jackpot determination counter as an initial value, and when the value is rounded to the same value as the initial value “0” by the update, a new initial value is acquired. Then, “1” is added to the initial value. This new initial value is repeatedly executed while the CPU 51 does not perform the main process (see FIG. 11) (until the main process ends and a new main process is started by an interrupt signal). A random number generated by an initial value random number process (a process for generating a random number by a predetermined algorithm) not shown is used. For example, when the random number generated by the initial value random number process is “18”, “19” and “20” are added by the update, and when it becomes “301140”, the process returns to “0”. “1” and “2” are added, and when “18” is reached, a new initial value is acquired. The maximum value of the jackpot determination counter may be a single set value, or setting means for selecting and setting different values such as setting 1, setting 2, and setting 3 may be provided.

  And, when the result of the first jackpot determination and the second jackpot determination is “big jackpot”, the hit special symbol creation counter is used to notify the first special symbol display unit 25 or the second special symbol display unit. 26 is used to determine the symbol displayed on the screen. Also, the special special symbol creation counter is used to notify the first special symbol display unit 25 or the second special symbol display unit when the result of the first big jackpot determination and the second big jackpot determination is “off”. 26 is used to determine the symbol displayed on the screen.

  In the present embodiment, the value of the hit special symbol creation counter is the maximum value “99” and the minimum value “0”. Then, “1” is added every interrupt (every 2 ms), and when it becomes “100” or more, it returns to “0”. The value of the winning special symbol creation counter is read when the game ball wins the first special symbol starting winning opening 15, and the winning special symbol determining random number column in the first jackpot relation information storage area 5205 (see FIG. 7). ). In addition, even when a game ball wins the left and right second ordinary electric actors 13a and 13b, the value of the winning special symbol creation counter is read, and the winning special symbol determining random number column of the second jackpot relation information storage area 5206 is read. (See FIG. 8). Further, the special symbol combination pattern storage area 5304 of the ROM 53 includes “probability variation / time-short design”, “probability variation / non-time-short design”, “non-probability variation / time-short design”, and “non-probability variation / non-time-short design”. Each of the four types of jackpot symbols is assigned and stored with a value of 0 to 99 as a hit special symbol determination random number. If the result of the jackpot determination is a jackpot, a combination of special symbols corresponding to the special symbol determination random number is determined as a “hit special symbol” according to the type of jackpot.

  Also, the special symbol creation counter value is the maximum value “575” and the minimum value “0”, and “1” is added every interrupt (every 2 ms) and becomes “576” or more. Return to "0". The value of the off-set special symbol creation counter is also read in response to the winning of the game ball in the first special symbol start winning port 15 and the left and right second ordinary electric accessories 13a and 13b, and the first jackpot relation information storage is performed. The special symbol determination random number column (see FIG. 7) in the area 5205 or the special symbol determination random number column (see FIG. 8) in the second jackpot relation information storage area 5206 is stored. Then, when the result of the jackpot determination is “missing”, a combination of special symbols corresponding to the stored value is determined as “missing special symbol”.

  The value of the variation pattern determination counter is used to determine the variation pattern of the special symbol. The variation pattern is a type of effect when notifying the result of the jackpot determination, and the variation pattern also determines the time from the start of variation to the stop of the first special symbol display unit 25 and the second special symbol display unit 26. It has been. The value of the variation pattern determination counter is the maximum value “99” and the minimum value “0”. When “1” is added every interrupt (every 2 ms) and becomes “100” or more, “ Return to "0". The variation patterns are provided with a jackpot variation pattern used at the time of jackpot and a loss variation pattern used at the time of loss. In the special symbol variation pattern storage area 5305 of the ROM 53, the variation pattern is “out of”. In each case, values of “0” to “99” are allocated and stored corresponding to the respective variation patterns. Then, the variation pattern is determined by using the value of the variation pattern determination counter in accordance with the result of the jackpot determination and the gaming state.

  Next, the first jackpot relation information storage area 5205 and the second jackpot relation information storage area 5206 will be described with reference to FIGS. FIG. 7 is a conceptual diagram showing a first jackpot relation information storage area of the RAM 52, and FIG. 8 is a conceptual diagram showing a second jackpot relation information storage area 5206 of the RAM 52. These two jackpot relation information storage areas 5205 and 5206 are used in a special symbol process (S14, see FIG. 11) of the main process described later.

  First, the first jackpot relation information storage area 5205 will be described. As shown in FIG. 7, the first jackpot relation information storage area 5205 is provided with a determination area, a first storage area, a second storage area, a third storage area, and a fourth storage area. In the special symbol process, when the winning of the game ball to the first special symbol start winning opening 15 is confirmed, the first storage area to the fourth storage area in the first jackpot relation information storage area 5205 Each value is stored in a storage area having a number corresponding to the value (first special symbol operation holding ball number) in the special symbol operation holding ball number storage area 5207. Each of the judgment area and the first memory area to the fourth memory area is provided with a big hit random number field, a hit special symbol determination random number field, an extraordinary special symbol determination random number field, a variation pattern determination random number field, and a winning time storage field , Jackpot random numbers, winning special symbol determination random numbers, outlier special symbol determination random numbers, variation pattern determination random numbers, and winning time values are stored. Specifically, the value of the jackpot determination counter is stored in the jackpot random number field, the value of the winning special symbol creation counter is stored in the bonus special symbol determination random number column, and the special symbol determination is made in the special symbol determination random number column. The value of the counter is stored, the value of the variation pattern determination counter is stored in the variation pattern determination random number column, and the game time is counted by the CPU 51 when the game ball wins the first special symbol start winning slot 15 in the winning time storage column. Is stored.

  Next, the second jackpot relation information storage area 5206 will be described. As shown in FIG. 8, the second jackpot relation information storage area 5206 is not provided with a fourth storage area unlike the storage area of the first jackpot relation information storage area 5205. Therefore, the number of various random numbers and winning times that can be stored is one less than the first jackpot relation information storage area 5205. When a game ball wins either the left second ordinary electric accessory 13a or the right second ordinary electric accessory 13b, the first storage area to the third storage area in the second jackpot relation information storage area 5206 Among the values stored in the first jackpot relation information storage area 5205 in the storage area of the number corresponding to the value of the second special symbol operation reservation ball number storage area 5208 (second special symbol operation reservation ball number) A value similar to is stored.

  Then, when the processing for the winning balls stored in the determination areas of the first jackpot relation information storage area 5205 and the second jackpot relation information storage area 5206 is completed, the processing of the next special symbol operation holding ball is performed. In the present embodiment, since the determination results of the first jackpot determination and the second jackpot determination are notified in the order in which the game balls are won at the starting opening, the first jackpot relation information storage area 5205 and the second jackpot relation information storage area 5206 are notified. When each value such as a random number is stored in only one of them (the holding ball is stored), the value stored in the first storage area is simply shifted to the determination area, and the determination area The notification of the jackpot determination result is executed based on the value stored in. As the first storage area is shifted to the determination area, the value in the second storage area is stored in the first storage area, the value in the third storage area is stored in the second storage area, and the first jackpot relation information is stored. In area 5205, the value in the fourth storage area is shifted in order to the third storage area, and the value in the storage area with the largest number is cleared. On the other hand, when a holding ball is stored in both the first jackpot relation information storage area 5205 and the second jackpot relation information storage area 5206, the winning times stored in the two first storage areas are compared. Thus, the determination result for the random number with the earlier winning time is notified. Details of this will be described later with reference to the flowcharts of FIGS.

  The number of storage areas of the first jackpot relation information storage area 5205 is four. That is, the number of game balls that have won the first special symbol start winning opening 15 can store a random number and hold the operation is four. On the other hand, since the number of storage areas of the second jackpot relation information storage area 5206 is three, the number of reserved balls that can be stored for the game balls won to the left and right second ordinary electric accessories 13a and 13b is three. One. Therefore, the upper limit of the number of special symbol operation reserved balls is seven, which is a state in which each value is stored in all the storage areas of the two jackpot relation information storage areas 5205 and 5206.

  Also, in the normal hit relation information storage area 5203 of the RAM 52, a determination area, a first storage area, a second storage area, a third storage area, and a fourth storage area are provided, and information on four game balls ( Normal random numbers) can be put on hold.

  Next, referring to FIG. 9 and FIG. 10, the first determination table and the second determination table stored in the first determination table storage area 5306 of the ROM 53 of the pachinko machine 1, which is the main part of the present invention. The second determination table stored in area 5307 will be described. 9 is a conceptual diagram showing a first determination table stored in the first determination table storage area 5306 of the ROM 53 of the pachinko machine 1, and FIG. 10 is a second determination table storage area 5307 of the ROM 53 of the pachinko machine 1. It is a conceptual diagram which shows the 2nd determination table memorize | stored in.

  The first determination table is referred to at the time of a first jackpot determination that determines whether or not a big hit is made when a game ball wins the first special symbol start winning opening 15. Furthermore, when it is determined that the first jackpot is determined to be a big hit, it is also referred to when determining whether or not to cause a probability variation state after the jackpot game and whether or not to cause a short-time gaming state. . Further, the second determination table is a second jackpot determination that determines whether or not the game ball wins the left and right second ordinary electric accessories 13a and 13b, and further, the second jackpot determination is determined to be a jackpot This is referred to when the probability variation success / failure determination and the short time / shortness determination are performed.

  As shown in FIG. 9, the first determination table is a first normal determination table used in a normal state in which the probability of being determined to be a jackpot is about 1/300, and the probability of being determined to be a jackpot is about 150. It is divided into the first high probability determination table used in the probability fluctuation state which is a probability of 1 /. Then, each of the values of the jackpot determination counters (jackpot random numbers) from 0 to 301139 is set to either “big jackpot” or “out of”. Furthermore, the success / failure of the probability variation state and the success / failure of the short-time gaming state are respectively set for the jackpot random number set to “big success”. Here, the first normal determination table and the first high probability determination table differ only in the probability of being determined to be a jackpot, and the probability determined to cause a probability fluctuation state when determined to be a jackpot, and the jackpot The probabilities of determining that a short-time gaming state is to be generated are determined to be equal. Then, the probability that it is determined that the probability variation state is caused is half, and the probability that it is determined that the time-saving gaming state is caused is also half.

  Further, as shown in FIG. 10, the second determination table is also divided into a second normal determination table and a second high probability determination table. And each jackpot random number is set to whether or not the jackpot is set, and the probability of being determined to be a jackpot is the same as in the first determination table. In addition, the probability of determining that a probability variation state is to be generated when it is determined to be a “hit” is also the same as that of the first determination table. Unlike the first determination table, the probability of being determined as is set to three-quarters, and this is a feature of the present invention.

  Here, in the pachinko machine 1 according to the first embodiment, the probability variation success / failure determination and the time-short / short-time determination are performed separately. One of the four gaming states of “time-short state”, “non-probability variation / time-short state”, and “non-probability variation / non-time-short state” will occur. Therefore, the game contents can be diversified as compared with the gaming machine that always causes the short-time gaming state when the probability variation state is generated. Further, in the first embodiment, when the second determination table is referred to and it is determined that the game is a big hit, even if the winning decision in the short time state is lost, the probability variation state is won. The game can be continued without being discouraged.

  Next, details of the operation of the main board 41 of the pachinko machine 1 according to the first embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 11 is a flowchart of main processing in the main board 41, and FIGS. 12 to 14 are flowcharts of subroutines of special symbol processing performed in the main processing of the first embodiment. Hereinafter, each step of the flowchart is abbreviated as “S”.

  The control of the pachinko machine 1 is performed by a control program stored in the control program storage area 5302 of the ROM 53. The main process of the control program is executed by the CPU 51 when the CPU 51 senses an interrupt signal generated by the interrupt signal generation circuit 57 (see FIG. 4). Since the interrupt signal is generated at regular intervals (2 ms in the present embodiment), the main process is repeatedly executed every 2 ms.

  First, with reference to FIG. 11, the main process performed with the main board | substrate 41 is demonstrated. As shown in FIG. 11, when the main process is started by sensing an interrupt signal, a command output process is first performed (S10). In this command output process, a control command is output to the sub-integrated board 58, the relay board 47, the symbol display board 44, and the payout control board 45 via the I / O interface 54. The control commands include a special symbol operation holding command indicating the number of special symbol operation holding balls, a normal symbol operation holding command indicating the number of normal symbol operation holding balls, a large winning opening opening command indicating the opening / closing timing of the big winning opening 16, and a large There are a winning mouth closing command, a special symbol stop command for instructing the timing for stopping the special symbol, a jackpot start screen display command for displaying a jackpot start screen, a variation pattern designation command for designating a variation pattern, and the like. The control command output here is a control command stored as an output command in the command relation storage area 5209 in the main process performed last time.

  Next, a switch reading process is performed (S11). This switch reading process is performed to the left and right normal symbol starting gates 12a and 12b, the first special symbol starting winning port 15, the left and right second normal electric accessories 13a and 13b, the big winning port 16, and the normal winning ports 19 and 20. A game ball winning is detected. Specifically, the first start opening switch 70 provided in the first special symbol start winning opening 15, the left second start opening switch 71 provided in the left second ordinary electric accessory 13a, the right second ordinary opening The right second start opening switch 72 provided in the electric accessory 13b, the normal symbol operation switches 73a and 73b provided in the right and left normal symbol start gates 12a and 12b, and the count switch provided in the special winning opening 16 75, a winning opening switch provided in the normal winning openings 19, 20 is used. When it is determined that the winning is made, the flag corresponding to each switch stored in the winning ball flag storage area 5202 of the RAM 52 is turned ON.

  Note that the main process performing the switch reading process is executed at intervals of the CPU 51 receiving the interrupt signal, that is, every 2 ms. Here, considering the speed at which the game ball passes through the switch and the size of the game ball, the switch reading process is performed a plurality of times while one game ball passes through the switch. Therefore, winning of one game ball is detected by a plurality of continuous switch reading processes. Therefore, for example, it is determined that the game ball has won a prize only when the state of “non-detection”, “detection”, and “detection” is reached in three consecutive executions of the switch reading process. At the start of the switch reading process, all the flags in the winning ball flag storage area 5202 are reset.

  When the switch reading process ends, a counter update process is then performed (S12). In this counter updating process, the values of the normal hit determination counter, the big hit determination counter, the hit special symbol creation counter, the extraordinary special symbol creation counter, and the variation pattern determination counter stored in the counter storage area 5201 of the RAM 52 are as described above. Only a fixed amount is added, and the values of the special symbol variation time counter, special symbol stop time counter, and jackpot start screen display time counter are subtracted by the predetermined amount. In addition, when the normal hit determination counter, big hit determination counter, hit special symbol creation counter, outlier special symbol creation counter, fluctuation pattern determination counter exceeds the maximum value of each counter, the value of each counter returns to the minimum value It has been programmed. Further, when each value of the special symbol variation time counter, the special symbol stop time counter, and the jackpot start screen display time counter becomes “0”, it is programmed not to perform further subtraction.

  When the counter update process ends, a special electric accessory process is performed (S13). In this special electric accessory process, a process related to a command for controlling the opening / closing operation of the big winning opening 16 in the big hit gaming state is performed. Specifically, control commands such as a big prize opening release command, a big prize opening closing command, and a jackpot end screen display command transmitted to the sub-integrated board 58 and the relay board 47 are stored in the command relation storage area 5209. . This special electric accessory processing is executed when “1” is stored in the jackpot gaming state flag stored in the flag relation storage area 5210 of the RAM 52 and is “ON”. The jackpot game state flag is set in the special symbol process (S14) when the jackpot notification is finished. When the next main process is performed, the operation in the big hit gaming state is started by this special electric accessory process. The jackpot game state flag is “OFF” when “0” is stored when the operation of the jackpot game state is terminated.

  When the special electric accessory process is completed, a special symbol process (S14) is performed. In this special symbol processing, determination of jackpot, determination of whether or not a probability variation state is generated after the end of the jackpot game, determination of whether or not the short-time gaming state is generated after the end of the jackpot game, and a symbol displayed on the display screen 28 And a change pattern, a change time determination, an instruction, an instruction to start and end the change of the symbol, and the like. This special symbol process will be described later with reference to the flowcharts shown in FIGS.

  When the special symbol process is completed, a normal electric accessory process is then performed (S15). In this ordinary electric combination processing, in the case of normal hit, the second ordinary electric combination 13a, 13b is made so that a game ball can be won to the left and right second ordinary electric combination 13a, 13b. A command for controlling opening / closing (normally hitting operation) of a pair of provided opening / closing members (so-called tulips) is stored in the command relation storage area 5209. Note that the normal hit determination is performed in the normal symbol processing of the next S16.

  In the next normal symbol process (S16), normal random numbers are obtained, normal hits are determined, and the like. When the flag corresponding to the normal symbol operation switches 73a and 73b in the winning ball flag storage area 5202 is set in the switch reading process of S11, the value of the normal hit determination counter is acquired. Then, “1” is added to the number of normal symbol operation reservation balls in the normal symbol operation reservation ball number storage area 5204. The number corresponding to the value stored in the normal symbol actuated holding ball number storage area 5204 in the first storage area to the fourth storage area of the normal hit relation information storage area 5203 is the value of the normal hit determination counter. Are normally stored as random numbers in the storage area. Then, the value of the first storage area is shifted to the determination area, the normal hit determination is performed based on the normal hit random number stored in the determination area, and the determination result is notified. As the value of the first storage area is shifted to the determination area, the value of the second storage area is also shifted to the first storage area. Then, the opening / closing members of the left and right second ordinary electric accessories 13a and 13b are opened and closed in the next ordinary electric accessory process (S15) of the main process. Here, in the special symbol processing (see FIG. 12 to FIG. 14) described later, the time-short state flag is set to ON, and when the time-short game state is in effect, the normal symbol variation time is shorter than the non-time-short state. .

  When the normal symbol process is completed, a payout process (S17) for paying out a prize ball is performed, and then an error check is performed (S18). If an error has occurred in the pachinko machine 1, an error is displayed on the display screen 28, the illumination lamp 63 is lit or blinked, or an error sound is generated from the speakers 32 and 33. Therefore, an error command for transmission to the sub-integrated board 58 in the command output process of S10 is stored in the command relation storage area 5209. Next, an information output process is performed (S19). In this information output process, various types of information such as jackpot information and starting information of the pachinko machine 1 are output via the output port 55 to a game hall management computer (not shown). When the information output process ends, the main process ends. When the interrupt signal is received from the interrupt signal generation circuit 57, the main process is executed again from the beginning.

  Here, a series of flows of the main process will be described by taking as an example the operation of the pachinko machine 1 when a certain game ball wins the first special symbol start winning opening 15 and is determined to be a big hit. When the player operates a launch handle 7 provided on the lower side of the game board 2 to launch a game ball into the game area 4, the game ball flows down the game area 4. When the game ball wins the first special symbol start winning opening 15, the winning of the game ball to the first special symbol start winning opening 15 is detected in the switch reading process, and the corresponding flag in the winning ball flag storage area 5202 is set. “ON” is set (S11). And the 1st special symbol display part 25 stops, and a jackpot symbol is stopped and displayed. When the jackpot symbol stop display ends, the jackpot gaming state flag in the flag related storage area 5210 is set to “ON” (S14). The winning opening 16 is opened, and the operation in the jackpot gaming state is started. Then, while the main process is repeatedly performed, the operation in the big hit gaming state is started according to the predetermined condition in the special electric accessory process (S13). Thereafter, when the jackpot gaming state is ended, the jackpot gaming state flag is set to “OFF”, and a series of operations relating to the game ball is ended.

  Next, the details of the special symbol process (S14) in the main process of the first embodiment will be described with reference to the flowcharts shown in FIGS. As described above, in special symbol processing, determination of jackpot, determination of whether or not to cause a probability variation state after the end of the jackpot game, determination of whether or not to cause a short-time gaming state after the end of the jackpot game, the first special symbol Determination of a special symbol displayed on the display unit 25 and the second special symbol display unit 26, determination of a variation pattern, etc., determination of a command to be output to the sub-integrated board 58, and the like are performed.

  First, the flags used in the special symbol process will be described. The flag relation storage area 5210 stores a display state flag, a jackpot gaming state flag, a probability variation flag, a short time state flag, and the like. The display state flag is a flag indicating the state of the first special symbol display unit 25 and the second special symbol display unit 26, and one of the first special symbol display unit 25 and the second special symbol display unit 26 changes. "1" is stored if it is (changed), "2" is displayed if either one is stopped (stopped display), and "0" is stored if both are changing or not stopped. ing. The jackpot gaming status flag is “1” stored and “ON” when the jackpot gaming state is set, and “0” is stored and “OFF” otherwise. . Further, the probability variation flag stores “1” during the probability variation state and is “ON”, and stores “0” when the probability variation state is not present and is “OFF”. . Further, the time-short state flag stores “1” during the time-short gaming state and is “ON”, and stores “0” when the time-short gaming state is not present and is “OFF”. . In both cases, the initial value is “0”.

  As shown in FIG. 12, when the special symbol process of the main process is started, a process related to winning a game ball at the first special symbol start winning opening 15 (denoted as “start opening 1” in the flowchart) is performed. Done. First, it is determined whether or not a game ball has won the first special symbol start winning opening 15 (S21). In the main process switch reading process (S11, see FIG. 11), when the first start port switch 70 provided in the first special symbol start winning port 15 detects the winning of the game ball, the winning ball flag is stored. The flag corresponding to the first start port switch 70 in the area 5202 is “ON”. Accordingly, in S21, it is determined whether or not the flag corresponding to the first start port switch 70 is “ON”. If it is not “ON” (S21: NO), the first special symbol start winning port is determined. Since the game ball has not won in 15, the process proceeds to S25 as it is.

  When the flag corresponding to the first start opening switch 70 is “ON” (S21: YES), since the game ball has won the first special symbol start winning opening 15, the random number for the game ball and The winning time is acquired and stored in the first jackpot relation information storage area 5205. However, the number of first special symbol actuated holding balls that can acquire and store random numbers and winning times is four. Accordingly, it is determined whether or not the value of the first special symbol operation reserved ball number storage area 5207 is “4” (S22). If the value of the first special symbol actuated ball number storage area 5207 is “4” (S22: YES), since the random number for this game ball cannot be stored, the process proceeds to S25 as it is.

  When the value of the first special symbol operation reserved ball number storage area 5207 is not “4”, that is, any of “0” to “3” (S22: NO), the first special symbol operation reserved ball number “1” is added to the value in the storage area 5207 (S23). Each random number and winning time is stored in the storage area of the number corresponding to the value of the first special symbol operation reserved ball number storage area 5207 among the first storage area to the fourth storage area of the first jackpot relation information storage area 5205. Stored (S24). That is, a game ball won in the first special symbol start winning opening 15 is stored as a holding ball. Specifically, the value of the jackpot determination counter is stored in the jackpot random number column, the value of the hit special symbol creation counter is stored in the bonus special symbol determination random number column, and the variation pattern determination counter value is stored in the variation pattern determination random number column. The value is stored, and the time at that time is stored in the winning time column.

  Next, processing related to winning a game ball to the left second ordinary electric accessory 13a (denoted as “starting port 2” in the flowchart) is performed. First, it is determined whether or not the game ball has won the left second ordinary electric accessory 13a (S25). This determination is made based on whether the flag corresponding to the left second start opening switch 71 provided on the left second ordinary electric accessory 13a among the flags stored in the winning ball flag storage area 5202 is “ON”. If it is not “ON” (S25: NO), the game ball is not won in the second left ordinary electric accessory 13a, and the process proceeds to S29 as it is. When the flag corresponding to the left second start-up switch 71 is “ON” (S25: YES), in order to determine whether or not there are three storage areas of the second jackpot relation information storage area 5206. In addition, it is determined whether or not the value of the second special symbol operation reserved ball number storage area 5208 is “3” (S26). If it is “3” (S26: YES), since the random number for this game ball cannot be stored, the process proceeds to S29 as it is.

  When the value of the second special symbol operation reserved ball number storage area 5208 is not “3”, that is, between “0” and “2” (S26: NO), the second special symbol operation reserved ball number “1” is added to the value of the storage area 5208 (S27). Each random number and winning time is stored in the storage area with the number corresponding to the value of the second special symbol operation reserved ball number storage area 5208 among the first storage area to the third storage area of the second jackpot relation information storage area 5206. Stored (S28).

  Next, processing related to winning a game ball to the right second ordinary electric accessory 13b (denoted as “starting port 3” in the flowchart) is performed. First, based on the value of the flag corresponding to the right second starting opening switch 72 provided on the right second ordinary electric accessory 13b, it is determined whether or not a game ball has won the right second ordinary electric accessory 13b. (S29). If the game ball has not won (S29: NO), the process proceeds to S33 (see FIG. 13). If the game ball has won (S29: YES), it is determined whether or not the value in the second special symbol actuated reserved ball number storage area 5208 is “3” (S30), and “3”. If this is the case (S30: YES), since the random number for this game ball cannot be stored, the process proceeds to S33 (see FIG. 13) as it is.

  When the value of the second special symbol operation reserved ball number storage area 5208 is not “3” (S30: NO), “1” is added to the value of the second special symbol operation reserved ball number storage area 5208 (S31). Each random number and winning time is stored in the storage area of the number corresponding to the value of the second special symbol operation reserved ball number storage area 5208 among the first storage area to the third storage area of the second jackpot relation information storage area 5206. (S32).

  Next, as shown in the flowchart of FIG. 13, it is determined whether or not the jackpot gaming state is based on the jackpot gaming status flag (S33). When it is a jackpot game state, the jackpot determination and the notification of the determination result are not performed. Therefore, if the jackpot gaming state flag is “ON” and the jackpot gaming state is set (S33: YES), the process returns to the main process without doing anything.

  If the jackpot gaming state flag is not “ON” (S33: NO), the game is not in the jackpot gaming state, and therefore processing related to the control of the first special symbol display unit 25 and the second special symbol display unit 26 is performed. First, based on the display state flag, it is determined whether either the first special symbol display unit 25 or the second special symbol display unit 26 is changing (S34). When the display state flag is not “1” and the two special symbol display parts 25 and 26 are not changing (S34: NO), one of the two special symbol display parts 25 and 26 is determined by the display state flag. Is determined whether or not is in a stopped display (S35). When the display state flag is not “2” and the two special symbol display units 25 and 26 are not stopped and displayed (S35: NO), a big hit determination is performed.

  Therefore, as shown in the flowchart of FIG. 14, it is confirmed whether or not there is a game ball to be subjected to the jackpot determination. First, it is determined whether or not the first reserved ball number is “1” or more based on the value of the first special symbol operation reserved ball number storage area 5207 of the RAM 52 (S41). (S41: YES), it is determined whether or not the second reserved ball number is “1” or more based on the value of the second special symbol actuated reserved ball number storage area 5208 (S42). When the number of first reserved balls is “1” or more and the number of second reserved balls is “0” (S41: YES, S42: NO), the process proceeds to S45 in order to perform the first big hit determination. To do. On the other hand, when both the number of the first reserved balls and the number of the second reserved balls are “1” or more (S41: YES, S42: YES) The winning time stored in the first determination area of the first jackpot relation information storage area 5205 (see FIG. 7) and the first determination area of the second jackpot relation information storage area 5206 (see FIG. 8) are stored. The winning time is compared to determine which winning time is earlier (S43). When the winning time of the first reserved ball is early (S43: YES), the process proceeds to S45 in order to perform the first jackpot determination first. If the winning time of the second reserved ball is early (S43: NO), the process proceeds to S60 in order to perform the second jackpot determination first.

  On the other hand, also when the number of first reserved balls is “0” (S41: NO), it is determined whether or not the number of second reserved balls is “1” or more (S44). When the number of first reserved balls is “0” and the number of second reserved balls is “1” or more (S41: NO, S44: YES), the process proceeds to S60 in order to perform the second jackpot determination. To do. Further, when both the first reserved ball number and the second reserved ball number are “0” (S41: NO, S44: NO), there is no game ball to be subjected to the jackpot determination, and the process directly returns to the main process. .

  In the first jackpot determination, first, “1” is subtracted from the value of the first special symbol action reserved ball number storage area 5207 (S45), and the value stored in the first jackpot relation information storage area 5205 is shifted. That is, the random number stored in the first storage area is shifted to the determination area, the random number stored in the second storage area is shifted to the first storage area, and the random number stored in the third storage area is The random number is shifted to the second storage area, the random number stored in the fourth storage area is shifted to the third storage area, and the value of the fourth storage area is cleared (S46).

  Next, the first jackpot determination is performed according to whether or not the state is a probability variation state (S47 to S49). The first jackpot determination is performed based on the jackpot random number stored in the jackpot random number column of the first jackpot relation information storage area 5205. In the case of the probability variation state in which “1” is stored in the probability variation flag and is “ON” (S47: YES), the first determination table (in the first determination table storage area 5306 of the ROM 53) ( A first jackpot determination is made with reference to the first high probability determination table of FIG. 9 (S48). When “0” is stored in the probability variation flag and is “OFF” (S47: NO), the first normal determination table in the first determination table (see FIG. 9) is referred to and the first jackpot determination is made. Is performed (S49).

  Next, when it is determined that the jackpot is determined to be a jackpot (S50: YES), the probability variation determination is performed based on the determination table used in the first jackpot determination, and the probability variation flag is set according to the determination result. Processing is performed (S51). Specifically, when it is determined that the probability variation state is to be generated, “1” is stored in the probability variation flag and is set to “ON”, and when it is determined that the probability variation state is not to be generated, the probability is “0” is stored in the variation flag and is set to “OFF”.

  Next, a determination of whether the time is short or short is performed based on the determination table used in the determination of the first jackpot, and processing of a time reduction state flag is performed according to the determination result (S52). Specifically, when it is determined that the short-time gaming state is caused to occur, “1” is stored in the short-time state flag and is set to “ON”, and when it is determined that the short-time gaming state is not caused, “0” is stored in the status flag and set to “OFF”. It should be noted that the short-time gaming state flag set to “ON” is set to “OFF” when the jackpot determination is performed 100 times or when it is determined next that the jackpot is determined.

  Next, a variation pattern determination process (S53) for jackpot and a special symbol determination process (S54) for jackpot are performed. Specifically, in the variation pattern determination process (S53), in the variation pattern determination table (not shown) at the time of jackpot stored in the special symbol variation pattern storage area 5305 of the ROM 53, the variation pattern determination random number (variation in the determination area) A variation pattern corresponding to (pattern determination random number) is determined. Then, a variation pattern designation command indicating the determined variation pattern is stored in the command relation storage area 5209. This variation pattern designation command is transmitted to the sub-integrated board 58 and the symbol display board 44 in the command output process (S10, see FIG. 11), and instructs the variation start of the designated special symbol together with the designation of the variation pattern. Furthermore, the variation time determined for each variation pattern is stored in the special symbol variation time counter. In the special symbol determination process (S54), one of the jackpot combinations stored in the special symbol combination pattern storage area 5304 is selected based on the value stored in the special symbol determination random number column of the determination area. The special symbol designation command indicating the selected special symbol is stored in the command relation storage area 5209. Then, the process proceeds to S72.

  On the other hand, when it is not determined to be a big hit by the first big hit determination (S50: NO), a fluctuation pattern determination process at the time of loss (S55) and an extra special symbol determination process (S56) are performed. Specifically, in the variation pattern determination process (S55), a variation pattern corresponding to the variation pattern determination random number is determined in a variation pattern determination table (not shown) when there is a deviation. Then, a variation pattern designation command indicating the determined variation pattern is stored in the command relation storage area 5209. Furthermore, the variation time determined for each variation pattern is stored in the special symbol variation time counter. Further, in the special symbol processing for outliers (S56), one of the combinations of outliers stored in the special symbol combination pattern storage area 5304 is selected based on the value stored in the outlier special symbol determination random number in the determination area, A special symbol designation command indicating the selected special symbol is stored in the command relation storage area 5209. Then, the process proceeds to S72.

  If it is determined in S41 to S44 that the second jackpot determination is to be performed, first, the value in the second special symbol operation reserved ball number storage area 5208 is decremented by “1” (S60). The value stored in the jackpot relation information storage area 5206 is shifted (S61). That is, the random numbers stored in the first storage area are shifted to the determination area, and the random numbers stored in the second storage area to the third storage area are shifted one by one to the storage area having one less number.

  Next, the second jackpot determination is performed based on the jackpot random number stored in the jackpot random number column of the second jackpot relation information storage area 5206 (S62 to S64). In the case of the probability variation state in which the probability variation flag is “ON” (S62: YES), the second determination table (see FIG. 10) stored in the second determination table storage area 5307 of the ROM 53 is used. A high jackpot determination is performed with reference to the high probability determination table (S63). When “0” is stored in the probability variation flag and is “OFF” (S62: NO), the second normal determination table of the second determination table (see FIG. 10) is referred to and the second jackpot determination is made. Is performed (S64).

  Next, when it is determined that the jackpot is determined by the second jackpot determination (S65: YES), the probability variation determination is performed based on the determination table used in the second jackpot determination, and the probability variation flag is set according to the determination result. Processing is performed (S66). Specifically, when it is determined that the probability variation state is to be generated, “1” is stored in the probability variation flag and is set to “ON”, and when it is determined that the probability variation state is not to be generated, the probability is “0” is stored in the variation flag and is set to “OFF”.

  Next, a determination of whether the time is short or short is performed based on the determination table used in the determination of the second jackpot, and processing of a time reduction state flag is performed according to the determination result (S67). Specifically, when it is determined that the short-time gaming state is caused to occur, “1” is stored in the short-time state flag and is set to “ON”, and when it is determined that the short-time gaming state is not caused, “0” is stored in the status flag and set to “OFF”.

  Next, in the variation pattern determination process (S68), a variation pattern determination table (not shown) stored in the special symbol variation pattern storage area 5305 is referred to, and a variation pattern determination random number (variation pattern determination in the determination area is determined). Variation pattern corresponding to (random number) is determined. Then, a variation pattern designation command indicating the determined variation pattern is stored in the command relation storage area 5209. Furthermore, the variation time determined for each variation pattern is stored in the special symbol variation time counter. In the jackpot special symbol process (S69), one of the jackpot combinations stored in the special symbol combination pattern storage area 5304 is selected based on the value stored in the hit special symbol determination random number column of the determination area. The special symbol designation command indicating the selected special symbol is stored in the command relation storage area 5209. Then, the process proceeds to S72.

  On the other hand, when it is not determined to be a big hit by the second big hit determination (S65: NO), in the fluctuation pattern determination process at the time of loss (S70), a fluctuation pattern determination table (not shown) in the case of a loss is referred. Thus, a variation pattern corresponding to the variation pattern determination random number is determined. Then, a variation pattern designation command indicating the determined variation pattern is stored in the command relation storage area 5209. Furthermore, the variation time determined for each variation pattern is stored in the special symbol variation time counter. Further, in the special symbol processing for losing (S71), one is selected from the combinations of the errants stored in the errant special symbol determining random number column of the determination area, and the special symbol designating command indicating the selected special symbol is stored in the command related storage area. 5209 is stored. Then, the process proceeds to S72.

  When the first jackpot determination and the second jackpot determination are finished and the processing related to the fluctuation pattern, the special symbol, and the like is finished, either the first special symbol display unit 25 or the second special symbol display unit 26 is changing. “1” indicating the presence is stored in the display state flag (S72), the special symbol process is terminated, and the process returns to the main process.

  In the determination of S34 shown in the flowchart of FIG. 13, when “1” is stored in the display state flag and it is determined that one of the two special symbol display portions 25 and 26 is changing. (S34: YES), it is determined whether or not the variation time has elapsed (S76). This determination is made based on the value of the special symbol variation time counter. When the value of the special symbol variation time counter set in S53, S55, S68, S70 (see FIG. 14) becomes “0”, the variation time has elapsed (S76: YES), so the command related storage area A special symbol stop command is stored in 5209 (S77). The special symbol stop command is transmitted to the sub-integrated board 58 and the symbol display board 44 in the command output process (S10, see FIG. 11), and the first special symbol display unit 25, the second special symbol display unit 26, and the demo symbol display. The stop of the parts D1 to D3 is instructed. Then, a predetermined stop display time (for example, 0.8 seconds) is stored in the special symbol stop time counter (S78), indicating that one of the two special symbol display units 25 and 26 is in a stop display. “2” is stored in the display state flag (S79). Then, the special symbol process is terminated and the process returns to the main process. On the other hand, if it is determined in S76 that the value of the special symbol variation time counter is not “0” and the variation time has not yet elapsed (S76: NO), the first special symbol display unit 25 or the second special symbol. The display unit 26 continues to change. Therefore, the special symbol process is terminated and the process returns to the main process.

  If it is determined in S35 that “2” is stored in the display state flag and one of the two special symbol display units 25 and 26 is determined to be stopped (S35: YES). ), It is determined whether or not the stop display time has elapsed (S80). This determination is made based on the value of the special symbol stop time counter. If the value of the special symbol stop time counter set in S78 is subtracted to “0” in the counter update process (S12, see FIG. 11), the stop display time has elapsed (S80: YES). “0” indicating that neither of the two special symbol display units 25 and 26 is in a stop display or in a change state is stored in the display state flag (S81). If the determination result of the first jackpot determination or the second jackpot determination is a jackpot (S82: YES), “1” is stored in the jackpot gaming state flag and set to “ON” (S83), and the jackpot start The screen display command is stored (S84). Next, a predetermined display time (for example, 11 seconds) is stored in the jackpot start screen display time counter (S85), the special symbol process is terminated, and the process returns to the main process. If it is not a big hit (S82: NO), the special symbol process is terminated as it is, and the process returns to the main process. If it is determined in S80 that the value of the special symbol stop time counter is not “0” and the stop display time has not yet elapsed (S80: NO), the first special symbol display unit 25 Alternatively, the second special symbol display unit 26 continues to display the symbols. Therefore, the special symbol process is terminated and the process returns to the main process.

  If the probability variation flag is set to “ON” in the processing of S51 or S66 (see FIG. 14), a probability variation state in which a jackpot determination with a high probability is performed after the jackpot game ends. . This probability fluctuation state continues until a non-stochastic fluctuation jackpot is won. In addition, when the time reduction state flag is set to “ON” in the processing of S52 or S67, the time reduction gaming state is generated after the end of the jackpot game. During the short-time gaming state, the variation time of the normal symbol controlled by the normal symbol processing (see S16, FIG. 11) and the variation time of the special symbol set by the special symbol processing S53, S55, S68, S70 are both Shorter than in non-time-saving gaming state. Furthermore, the open time of the left and right second ordinary electric actors 13a and 13b controlled by the ordinary electric accessory process (S15: see FIG. 11) becomes longer than that in the non-short game state. Therefore, during the short-time gaming state, the number of jackpot determinations made within a predetermined time and the number of game balls to be paid out increase, so that the gaming state is more advantageous to the player than the non-short-time state. During the short-time gaming state, the number of times the first special symbol display unit 25 and the second special symbol display unit 26 have changed is counted by the counter, and the total number of changes reaches 100 times, or it is determined that it is the next big hit. When either of the two conditions is satisfied, “0” is stored in the time reduction state flag and is set to “OFF”.

  As described above, when the game ball wins the first special symbol start winning opening 15 (S21: YES), various random numbers and winning times are stored in the first jackpot relation information storage area 5205 (S24). That is, the holding ball is stored. Further, when the game ball wins the left second ordinary electric accessory 13a and the right second ordinary electric accessory 13b (S25: YES or S29: YES), various random numbers and winning times are stored in the second jackpot relation information storage area 5206. Is stored (S28, S32). Then, each value is shifted to the determination area in the order of the winning time (S46, S61), and the first jackpot determination and the second jackpot determination are performed. When it is determined that the game is a big hit, whether the probability variation state is correct (S51, S66) and the short-time gaming state is determined (S52, S67). It is different between the big jackpot and the second jackpot (see FIGS. 9 and 10).

  As described above, the pachinko machine 1 according to the first embodiment includes the two jackpot relation information storage areas 5205 and 5206 having a plurality of storage areas, and the game ball wins the first special symbol start winning opening 15. In the case where the game ball is won in the first jackpot relation information storage area 5205 and the left and right second ordinary electric actors 13a and 13b, the jackpot random number is stored in the second jackpot relation information storage area 5206. The first jackpot determination for the jackpot random number stored in the first jackpot relation information storage area 5205 and the second jackpot determination for the jackpot random number stored in the second jackpot relation information storage area 5206 shorten the time after the jackpot game ends. The probabilities determined to cause a gaming state, that is, the short-time gaming state entry rate are different. Therefore, since the value given to the player differs depending on which winning opening the game ball has won, it is possible to entertain the game by making the player interested in which winning opening the game ball will win.

  In addition, it stores whether or not each jackpot random number is a random number that has been determined to be a jackpot in advance. A determination table for storing information for determining whether or not to perform the determination. Therefore, a random number for determining whether or not a big hit, a random number for determining whether or not a short-time gaming state is caused, and a random number for determining whether or not a probability variation state is caused are obtained separately. Since there is no need to do this, the control is simplified and the burden on the gaming machine is reduced.

  In addition, since a single jackpot random number is used to separately determine whether or not to generate a short-time gaming state and whether or not to generate a probability variation state, Four game states can be generated: “non-time-short state”, “non-probability variation / time-short state”, and “non-probability variation / non-time-short state”. Therefore, the game content can be diversified as compared with the gaming machine that always causes the short-time gaming state simultaneously with the probability variation state, and the player's interest can be attracted.

  Further, since the right and left second ordinary electric accessories 13a and 13b cannot win game balls unless the opening and closing members are opened, it is more difficult for the game balls to win than the first special symbol start winning opening 15. That is, the frequency at which random numbers are stored in the second jackpot relation information storage area 5206 is lower than the frequency at which random numbers are stored in the first jackpot relation information storage area 5205. Further, only up to three jackpot random numbers can be stored by winning the game balls to the left and right second ordinary electric accessories 13a, 13b, while jackpot random numbers by winning the game balls to the first special symbol start winning opening 15 can be stored. Can store up to four. The probability that the short-time gaming state is generated when the random number is stored in the second jackpot relation information storage area 5206 with a low frequency of storing random numbers and a small number of random numbers that can be stored is determined to be a jackpot. Is set to be high. In this way, when a game ball wins a winning opening with a low winning frequency (high difficulty of winning) and a winning ball has a high winning frequency (low winning difficulty) By setting the value given to the player higher than that, it is possible to enhance the player's sense of expectation when the game ball wins a winning opening with a high difficulty level of winning.

  The first special symbol start winning opening 15, the left second ordinary electric accessory 13a, and the right second ordinary electric accessory 13b correspond to the "winning opening" in the present invention. The start port switch 71 and the right second start port switch 72 correspond to “game ball detecting means”. Further, in the special symbol processing S24, S28, and S32 of the special symbol processing shown in FIG. 12, a main jack random number is acquired and stored in either the first jackpot relation information storage area 5205 or the second jackpot relation information storage area 5206. The CPU 51 of 41 functions as “big hit random number acquisition means”. In addition, the first jackpot relation information storage area 5205 and the second jackpot relation information storage area 5206 of the RAM 52 correspond to “big hit random number storage means”. Further, in the processing of S48, S49, S63, and S64 shown in FIG. 14, the CPU 51 of the main board 41 that determines whether or not the stored jackpot random number is a random number that is determined in advance as a jackpot as “jackpot determination means”. Function.

  The display screen 28 corresponds to “symbol display means” in the present invention, and the effect control board 43 corresponds to “symbol display control means”. Further, the special winning opening 16 corresponds to a “variable winning opening”, and the first determination table storage area 5306 and the second determination table storage area 5307 of the ROM 53 correspond to “determination table storage means”. Further, in the processing of S51 and S66 shown in FIG. 14, the CPU 51 of the main board 41 that determines whether or not to generate a probability variation state using the determination table and the jackpot random number functions as a “probability variation state determination unit”. In the processes of S52 and S67, the CPU 51 of the main board 41 for determining whether or not to generate a short-time gaming state functions as a “short-time gaming state determination unit”.

  Next, a pachinko machine 100 that is a second embodiment of the gaming machine according to the present invention will be described with reference to FIGS. FIG. 15 is a front view of the game board 102 of the pachinko machine 100. 16 is a conceptual diagram showing a first determination table stored in the first determination table storage area 5306 of the ROM 53 of the pachinko machine 100, and FIG. 17 is a second determination table storage of the ROM 53 of the pachinko machine 100. It is a conceptual diagram which shows the 2nd determination table memorize | stored in the area 5307. FIG. 18 is a flowchart of a special symbol processing subroutine performed in the main process of the pachinko machine 100, and FIG. 19 is a flowchart of a special electric accessory process subroutine performed in the main process of the pachinko machine 100. It is a flowchart.

  The pachinko machine 100 according to the second embodiment is provided with two big winning holes (the first big winning hole 17 and the second big winning hole 18) on the game board 102, and two types are determined when it is determined that the game is a big hit. Jackpots (jackpot A and jackpot B) can be generated. When the jackpot A is raised, the first big winning opening 17 is opened and closed 15 times, and when the big hit B is raised, the second big winning opening 18 is opened and closed five times, so that the big hit A is raised. In this case, more game balls are paid out than when the jackpot B is generated. The first jackpot determination for the jackpot random number stored in the first jackpot relation information storage area 5205 and the second jackpot determination for the jackpot random number stored in the second jackpot relation information storage area 5206 include a jackpot for the jackpot The probabilities of being judged as A, that is, the round number selection probabilities are different, and this point has a feature.

  First, the mechanical configuration of the pachinko machine 100 according to the second embodiment will be described with reference to FIG. As shown in FIG. 15, the game board 102 of the pachinko machine 100 is provided with a second big prize opening 18 and a first big prize opening 17 arranged vertically below the first special symbol start winning opening 15. The first grand prize winning port 17 and the second grand prize winning port 18 are provided with an opening / closing member, and the game ball wins only when the opening / closing member is opened (when the big winning ports 17 and 18 are opened). Is possible. The other mechanical configurations are the same as the mechanical configuration of the pachinko machine 1 shown in FIGS.

  Moreover, the combination of the special symbol displayed on the 1st special symbol display part 25 and the 2nd special symbol display part 26 is common, and a total of 676 types of combinations are provided. And 100 kinds of 2-digit combinations of 10 kinds of alphabets of A, C, E, F, H, J, L, P, U, and Y are regarded as “special hits”, and 576 kinds of other combinations are It is said to be a “special pattern”. This “hit special symbol” is provided with “hits a special symbol” and “hits B special symbol” for each combination, and if it is determined to be a big hit, whether the big hit is “hit A” or “ A special symbol is determined according to whether the jackpot is "B". In addition, in the demo symbol display portions D1 to D3, when “big hit A” is shown, odd demo symbols or character symbols are displayed together, and when “big hit B” is shown, even demo symbols are aligned. Display. The other mechanical configurations are the same as the mechanical configuration of the pachinko machine 1 shown in FIGS.

  Next, the electrical configuration of the pachinko machine 100 will be described. The electrical configuration of the pachinko machine 100 is the same as the electrical configuration of the pachinko machine 1 (see FIG. 4), but the opening / closing member of the first grand prize opening 17 instead of the big prize opening solenoid 74 connected to the relay board 47. And a second big prize opening solenoid 78 that opens and closes the opening / closing member of the second big prize opening 18. Further, in place of the count switch 75 shown in FIG. 4, a first count switch 79 for detecting the winning of the game ball to the first big winning opening 17 and a winning of the game ball to the second big winning opening 18 are detected. A second count switch 80 is provided. And the other electrical configuration of the pachinko machine 1 shown in FIG. 4 is the same as the configuration of the pachinko machine 100 of the second embodiment, and thus the description thereof is omitted.

  Next, with reference to FIG.16 and FIG.17, the 1st determination table and the 2nd determination table in the pachinko machine 100 of 2nd embodiment are demonstrated. The first determination table is referred to when a first jackpot determination is made to determine whether or not a big hit is made when a game ball wins the first special symbol start winning opening 15, and when the first jackpot determination is determined to be a big hit In addition, it is also used to determine which of “big hit A” and “big hit B” occurs. Further, the second determination table is determined to be a big hit by a second jackpot determination that determines whether or not a big hit is made when a game ball wins the right and left second ordinary electric accessories 13a and 13b, and further, a second jackpot determination. Is used to determine which of “big hit A” and “big hit B” occurs.

  As shown in FIG. 16, in the first determination table of the pachinko machine 100, either “big hit” or “out of place” is set for each of the values of the big hit determination counters (big hit random numbers) from 0 to 301139. Further, in the jackpot random number set to “big jackpot”, it is set which type of jackpot is generated, “big jackpot A” or “big jackpot B”. In the first determination table, the probability that the jackpot will be determined is set to about 1/300, and the probability that the jackpot A will be generated when the jackpot is determined is set to about 1/10. Yes.

  In addition, as shown in FIG. 17, in the second determination table, whether or not the jackpot is set for each jackpot random number is set, and the probability of determining that the jackpot is about 1/300 as in the first determination table. . However, unlike the first determination table, the probability that it will be determined that the “big hit A” will occur when the jackpot is determined is set to about 9/10, and this point has the characteristics of the present invention. . With this configuration, the average value of the number of rounds when it is determined to be a big hit by the first determination table is “6 times”, whereas the average value of the number of rounds when it is determined to be a big hit by the second determination table Becomes “14 times”. The configurations of the ROM 53, the ROM 52, etc. of the pachinko machine 1 shown in FIGS. 4 to 8 are the same as the configuration of the pachinko machine 100 of the second embodiment, and thus description thereof is omitted.

  Next, with reference to FIG. 18, the special symbol process performed by the main process of the pachinko machine 100 which is 2nd embodiment is demonstrated. Since the special symbol processing of the pachinko machine 100 is the same as the special symbol processing of the pachinko machine 1 shown in FIGS. 12 to 14 except for a part of the special symbol processing shown in FIG. 18, the pachinko machine 1 shown in FIG. Steps similar to those in the special symbol processing are given the same step numbers in FIG. 18 and description thereof is omitted.

  In the special symbol processing in the pachinko machine 100, when the first jackpot determination is made (S42: NO or S43: YES), the number of the first special symbol operation holding balls is subtracted by “1” (S45), and the first jackpot relation information After the value of the first storage area in the storage area 5205 (see FIG. 7) has been shifted to the determination area (S46), the big hit determination is performed by the first determination table (see FIG. 16) (S101). If it is determined that the jackpot is made (S50: YES), the jackpot type determination of “big jackpot A” or “big jackpot B” is made based on the first determination table (S102). Next, a flag corresponding to the determined jackpot type is set (S103). Specifically, when it is determined that the “big hit A” is to be generated, the jackpot A occurrence flag stored in the flag relation storage area 5210 of the RAM 52 indicates that the “big hit A” is being generated. “1” is stored and turned “ON”. On the other hand, when it is determined that “big hit B” is to be generated, “0” indicating that “big hit B” is being generated is stored in the big hit A occurrence flag in the flag relation storage area 5210 and “ OFF ”. Then, in the jackpot special symbol determination process (S54), the bonus special symbol displayed on the first special symbol display unit 25 is determined according to which of “big jackpot A” and “big jackpot B” occurs.

  When the second jackpot determination is made (S43: NO or S44: YES), the number of second special symbol operation reserved balls is decremented by “1” (S60), and the second jackpot relation information storage area 5206 (FIG. 8) is shifted to the determination area (S61), and then the big hit determination is performed by the second determination table (see FIG. 17) (S105). If it is determined that the jackpot is made (S65: YES), the jackpot type determination of “big jackpot A” or “big jackpot B” is made based on the second determination table (S106). Specifically, when it is determined that the “big hit A” is to be generated, “1” is stored in the jackpot A occurrence flag and is set to “ON”, and when it is determined that the “big hit B” is to be generated. “0” is stored in the jackpot A occurrence flag and is set to “OFF”. In the jackpot special symbol process (S69), the bonus special symbol displayed on the second special symbol display unit 26 is determined according to the jackpot type.

  Next, with reference to FIG. 19, the special electric accessory process (S13, refer FIG. 11) performed by the main process in the pachinko machine 100 of 2nd embodiment is demonstrated. In this special electric accessory processing, when “big hit A” is generated, processing for opening and closing the first big winning opening 17 is performed 15 times, while “big hit B” is generated A process for opening and closing the second big prize opening 18 is performed five times. Note that flags used in the special electric accessory processing include a big prize opening open flag and a big prize opening closed flag, which are stored in the flag related storage area 5210 of the RAM 52. The big prize opening open flag stores “1” and is “ON” when one of the two big prize winning openings 17 and 18 is open. In addition, the flag for closing the big prize opening is stored as “1” when the two big prize winning openings 17 and 18 are both closed, and is set to “ON”. Further, a round number counting counter is used to count the number of rounds of 5 or 15 times. This initial value is “0”.

  As shown in FIG. 19, when the special electric accessory process of the main process is started, it is determined whether or not the jackpot gaming state is based on the jackpot gaming state flag (S121). When it is not in the jackpot gaming state, the big winning openings 17, 18 are not opened / closed. Therefore, when the jackpot gaming state flag is “OFF” and the jackpot gaming state is not set (S121: NO), the process returns to the main process without doing anything.

  On the other hand, when the jackpot gaming state flag is “ON” and the jackpot gaming state is set (S121: YES), processing relating to the opening / closing of the big prize winning openings 17 and 18 is performed. First, it is determined whether or not the closing time of the special winning openings 17 and 18 is being closed (S122). When the big prize opening closing flag indicating that the big prize openings 17 and 18 are closed is “OFF” (S122: NO), whether or not the big prize openings 17 and 18 are being opened. Is determined (S123). When the big prize opening opening flag indicating that either of the big prize winning openings 17 and 18 is open is “OFF” (S123: NO), the big prize winning opening 17 is set according to the type of the big hit. , 18 is released. When the jackpot A occurrence flag is “ON” and “jackpot A” is raised (S124: YES), a first big prize opening command for opening the first big prize opening 17 is issued. And stored in the command relation storage area 5209 of the RAM 52 (S125). On the other hand, when the jackpot A occurrence flag is “OFF” and “jackpot B” is raised (S124: NO), the second big prize opening for opening the second big prize opening 18 The release command is stored (S126). Next, a big winning opening opening time counter for measuring the maximum opening time (30 seconds) of the big winning openings 17, 18 is stored in the counter storage area 5201 of the RAM 52, and the big winning opening open flag is “ON”. (S127).

  Next, a determination is made as to whether or not the number of winning balls for the winning balls 17 and 18 is “9” (S128). Every time a game ball wins a prize winning port 17 or 18, "1" is added to the value of the prize winning ball number counter in the switch reading process (S11, see FIG. 11). If the value of the winning ball counter is less than 9 (S128: NO), whether or not the maximum opening time of the big winning holes 17, 18 has passed by the big winning hole opening time counter set in the process of S127. Is determined (S129). If the maximum opening time of 30 seconds has not elapsed (S129: NO), the process directly returns to the main process.

  Then, in the special electric accessory processing of the main process performed after that, it is a big hit gaming state (S121: YES), not during the closing time of the big prize opening 16 (S122: NO), the big prize opening 17, 18 If it is open (S123: YES), these determinations are repeated until the number of winning balls reaches 9 or until the maximum opening time of the big winning openings 17, 18 elapses (S128: NO, S129: NO). Then, when the number of winning balls is 9 (S128: YES), or when the maximum opening time of 30 seconds has elapsed (S129: YES), a process for closing the special winning openings 17, 18 is performed. . Therefore, a special winning opening closing command for closing the special winning openings 17 and 18 is stored in the command related storage area 5209 (S130). Next, a big prize opening closing time counter for measuring a closing time (three seconds) until the next big prize winning openings 17 and 18 are opened is stored in the counter storage area 5201 (S131), and the big prize winning prize is received. The value of the ball counter is initialized to “0” which is an initial value (S132). Next, the special winning opening open flag is set to “OFF”, the special winning opening closed flag is set to “ON” (S133), and the process returns to the main process.

  In addition, when the big prize opening closing flag is “ON” and the two big prize winning openings 17 and 18 are both closed (S122: YES), the closing time of the big prize winning openings 17 and 18 has elapsed. Is determined (S134). If the value of the winning prize closing time counter is not “0” and the closing time is being measured (S134: NO), the process directly returns to the main process. On the other hand, when the value of the winning prize closing time counter is “0” and the closing time has elapsed (S134: YES), “0” is stored in the closing prize closing flag and “OFF” is stored. (S135), "1" is added to the value of the round number counter in the counter storage area 5201 (indicated as "G" in the flowchart) (S136).

  Next, it is determined whether or not to end the jackpot game according to the type of jackpot. When the big hit A occurrence flag is set to “OFF” and “big hit B” is raised (S137: NO), it is determined whether or not the value of the round count counter is “5” ( S138). As described above, when the “big hit B” is generated, the opening / closing operation of the second big winning opening 18 is one round, and the opening / closing operation of five rounds is performed during one big hit game. Done. The initial value of the round number counter is “0”, and “1” is added to the value of the round number counter every time the opening / closing operation of one round is completed. At the time of 5 ", the opening / closing operation for 5 rounds is completed. Accordingly, when the value of the round number counting counter is not “5”, that is, any value from “1” to “4” (S138: NO), the opening / closing operation of the special winning opening 18 is performed again. Return to the main process as it is. On the other hand, when the value of the round count counter is “5” (S138: YES), a process of ending the jackpot game is performed.

  If the jackpot A occurrence flag is set to “ON” and “jackpot A” has occurred (S137: YES), it is determined whether or not the value of the round count counter is “15”. Is called. When the “big hit A” is generated, the big hit game is ended after opening and closing the first big winning opening 17 15 times. Therefore, when the value of the round number counter is not “15” (S139: NO), the process returns to the main process. On the other hand, when the value of the round count counter is “15” (S139: YES), a process of ending the jackpot game is performed.

  In the process of ending the jackpot game, first, “0” indicating that the jackpot game state flag is not the jackpot game state is stored and set to “OFF” (S140). Next, a jackpot end screen display command for displaying a screen indicating that the jackpot game has ended is stored in the command relation storage area 5209 (S141), and the value of the round number counter is initialized to “0” which is an initial value. (S142), the special electric accessory process is terminated, and the process returns to the main process.

  As described above, the pachinko machine 100 according to the second embodiment includes the two jackpot relation information storage areas 5205 and 5206 having a plurality of storage areas, and a game ball is supplied to the first special symbol start winning opening 15. When winning, the first big hit relation information storage area 5205 is stored, and when the game ball wins the left and right second ordinary electric accessories 13a, 13b, the big hit random information is stored in the second big hit relation information storage area 5206. . The first jackpot determination for the jackpot random number stored in the first jackpot relation information storage area 5205 and the second jackpot determination for the jackpot random number stored in the second jackpot relation information storage area 5206 are determined to be a jackpot. Probability is the same, but when it is determined to be a big hit, the probability that it will cause a “big hit A” to open and close the first big prize opening 17 15 times, and the second big prize opening 18 will be opened and closed five times The probability that it will be determined that the “big hit B” to be generated is different. Specifically, the average number of rounds when the first jackpot determination is determined to be a jackpot is “6”, and the average number of rounds when the second jackpot determination is determined to be a jackpot is “14”. . That is, the average value of the number of rounds, which is the number of times of opening / closing the special winning openings 17, 18, is different. Therefore, since the value given to the player differs depending on which winning opening the game ball has won, it is possible to entertain the game by making the player interested in which winning opening the game ball will win.

  In the second embodiment, the first big prize opening 17 is opened and closed when the “big hit A” is raised, and the second big prize opening 18 is opened when the “big hit B” is raised. Open and close. Thereby, the player can easily determine which of “big hit A” and “big hit B” has occurred by observing which of the first big prize opening 17 and the second big prize opening 18 is opened or closed. can do. It should be noted that the first big prize port 17 and the second big prize port 18 in the pachinko machine 100 of the second embodiment correspond to the “variable prize port” in the present invention.

  It should be noted that the present invention is not limited to the embodiment described in detail above, and it is needless to say that various modifications can be made without departing from the gist of the present invention. First, the short-time gaming state entry rate in the first embodiment and the round number selection probability in the second embodiment are different for each jackpot related information storage area in which the jackpot random number is stored. It can also be set as the structure from which a rush rate differs. In this case, for example, in the determination tables shown in FIGS. 9 and 10, the setting of the “probability change success / failure” column may be changed to change the probability determined to cause the probability change state for each determination table. As a result, the value given to the player differs depending on which winning opening the game ball has won, so that the player can enjoy the game with an interest in which winning opening the game ball wins.

  In addition, a plurality of probabilities among the probability variation state entry rate, the short time gaming state entry rate, and the round number selection probability can be changed for each jackpot related information storage area. And each probability which changes for every jackpot relation information storage area can also be set arbitrarily. For example, the probability variation state entry rate and the short-time gaming state entry rate may be different between the first jackpot relation information storage area 5205 and the second jackpot relation information storage area 5206. In this case, both the probability variation state rush rate and the short-time gaming state rush rate may be set so that the second jackpot relationship information storage area 5206 is higher, and the probability variation state rush rate is the first jackpot relationship information. While the storage area 5205 is set higher, the short-time gaming state rush rate can be set higher in the second jackpot relation information storage area 5206.

  In the first and second embodiments, the right and left second ordinary electric accessories 13a and 13b cannot win game balls unless the opening and closing members are opened. Infrequent. As a result, the difficulty level of winning a prize opening corresponding to each jackpot related information storage area is determined, and each probability is changed according to this difficulty level, but the difficulty level of winning a prize is determined using other criteria. You can also For example, in a configuration in which a predetermined number of game balls are fired per unit time by a launching device, the number of game balls that have won a prize at each winning opening within a predetermined time is counted, and the number of game balls that have been won is small. It is possible to determine that the difficulty level of the winning a prize port is high, and it is also possible to determine the difficulty level based on the position of the winning a prize port. In addition, when the number of winning prize openings corresponding to each jackpot related information storage area is different, it can be determined that the smaller the number of corresponding winning prize openings, the higher the difficulty level until a random number is stored. And by setting the jackpot-related information storage area with a higher degree of difficulty so that the value given to the player is higher, the player's sense of expectation when the game ball wins a winning opening with a higher degree of difficulty Can be increased.

  Moreover, the form of the winning opening in the first and second embodiments can be changed as appropriate. For example, the number of winning holes is not limited to three, and the number of ordinary electric accessories is not limited to two. Also, the first special symbol start winning opening 15 can be used as a normal electric accessory, and the left and right second normal electric accessories 13a and 13b can be used as a winning opening not provided with an opening / closing member. Either one of the electric accessories 13a and 13b can be a winning opening not provided with an opening / closing member. For example, the first jackpot relation information storage area 5205 is associated with one winning opening without an opening / closing member and one ordinary electric accessory, and the second jackpot relation information storage area 5206 is associated with two ordinary electric actors. be able to. In this case, in the first jackpot relation information storage area 5205 corresponding to the winning opening not provided with an opening / closing member, the degree of difficulty of winning the game ball (a jackpot random number is stored) than the second jackpot relation information storage area 5206. Difficulty). Then, by setting the second jackpot relation information storage area 5206 having a higher degree of difficulty so that the value given to the player is higher, when the game ball wins a winning opening with a higher degree of difficulty for winning The expectation of the player can be increased.

  In the first and second embodiments, one winning opening (first special symbol start winning opening 15) is provided in the first jackpot relation information storage area 5205, and two winning prizes are provided in the second jackpot relation information storage area 5206. The mouths (left and right second ordinary electric accessories 13a, 13b) correspond to each other, but the number of winning mouths and the number of jackpot relation information storage areas are made equal to each other. It is also possible to make a winning opening. In this case, since the value given to the player when it is determined to be a big hit differs depending on which winning opening the game ball has won, the game content is simple and easy to understand.

  In the first and second embodiments, one means for storing ordinary hit random numbers and two means for storing big hit random numbers are provided, but these numbers can be changed as appropriate. For example, the right and left normal symbol start gates 12a and 12b are not provided, and the left and right second ordinary electric accessories 13a and 13b are both changed to a winning opening not provided with an opening / closing member, so that the game machine does not perform a normal hit determination. For example, the normal hit relation information storage area 5203 can be omitted. On the other hand, a normal hit determination for determining whether or not to open the left second ordinary electric accessory 13a, and an ordinary hit determination for determining whether or not to open the right second ordinary electric accessory 13b. When performing these separately, it is sufficient to provide two means for storing random numbers per ordinary.

  In addition, the pachinko machine 100 of the second embodiment is provided with two big winning holes 17 and 18, and when the “big hit A” is caused, the first big winning hole 17 is caused 15 times and the “big hit B” is raised. In some cases, the second big prize opening is opened and closed five times, that is, the first big prize opening 17 is dedicated to “Big Jack A” and the second big prize opening 18 is dedicated to “Big Jack B”. I can't. For example, when the “big hit A” is caused, the two big winning openings 17 and 18 are both opened, and when the “big hit B” is caused, one of the big winning openings 17 and 18 is opened. Alternatively, both of the two big winning openings 17, 18 may be opened at the time of a big win. Needless to say, it is possible to change only the number of times of opening and closing with a single prize opening.

  In addition, the number of prize balls to be paid out when a game ball is won can be set differently between the first grand prize opening 17 and the second big prize opening 18. Specifically, one game ball is won in the second big prize opening 18 that is opened and closed five times, compared to the case where the game ball is won in the first big prize opening 17 that is opened and closed 15 times. It is also possible to set so that the number of game balls to be paid out with respect to the winning of the game balls increases or decreases. With such a configuration, the contents of the game can be further diversified, and it is possible to determine which of the jackpots, “Big Jack A” or “Big Jack B” is caused by the difference in the number of prize balls to be paid out. The player can be notified.

  In the second embodiment, the jackpots of different numbers of rounds are generated by providing two types of jackpots, “Big Jack A” and “Big Jack B”. For example, three or more jackpots are provided. The number of rounds may be different from each other, or the jackpot game may be performed by directly drawing the number of rounds without dividing the jackpot type. In addition, the number of rounds of “big hit A” and “big hit B” is not limited to 15 and 5, and can be changed as long as the round number of big hit A is larger than the round number of big hit B. Needless to say. Also, the round number selection probability can be changed according to the difference between the number of rounds of jackpot A and the number of rounds of jackpot B.

  In addition, the determination methods of jackpot determination, probability variation determination, short-time determination, and round number determination can be changed as appropriate. For example, in the first and second embodiments, the first jackpot determination table and the second jackpot determination table are provided separately, and the jackpot determination is performed separately for each jackpot relation information storage area, but the jackpot determination is the same While making a determination with reference to the determination table, it is also possible to make only other determinations, such as a determination of whether or not to shorten the time, for each jackpot related information storage area. In addition, the determination probability such as the short / short time determination can be changed for each jackpot related information storage area only during a specific gaming state. In this case, for example, the determination probabilities such as the determination of whether or not the time is short may be changed for each jackpot related information storage area during the normal state, and the determination probabilities may be set to be the same during the probability variation state.

  Further, other forms of the gaming machine can be changed as appropriate. For example, in the first embodiment, in the case of a jackpot that causes a short-time gaming state, odd or character demo symbols are displayed in alignment with the demo symbol display units D1 to D3. In the case of a jackpot that causes an occurrence of the symbol, odd or character demo symbols may be displayed together, or the type of jackpot may be notified by changing the color, pattern, background, etc. of the demo symbol.

  The gaming machine of the present invention is not limited to a pachinko machine, and can be applied to various gaming machines such as a pachikon machine and a pachislot machine.
