Description

  The present invention relates to a gaming machine.

  2. Description of the Related Art Conventionally, a gaming machine that gives a certain game value to a game medium such as a medal or a pachinko ball and performs a game for acquiring a game medium such as a medal or a pachinko ball is known. This type of gaming machine has a control process for acquiring a random number from a counter that generates a random number and referring to the acquired random number and a data table as a control process related to the progress of the game, the provision of game media, and the like.

  In the above-described gaming machine, when a control process that refers to the acquired random number and the data table is executed a plurality of times using a counter that generates a random number that circulates at a certain period, the same period until the random number circulates Discloses a technique for obtaining a plurality of random numbers from one counter (for example, Patent Document 1). In general, in gaming machines, the counter is configured so that the same random number does not occur within the cycle in which the random number circulates.Therefore, when there is an opportunity to acquire multiple random numbers within the same cycle until the random number circulates, Random numbers acquired after the second time will be obtained without the random numbers acquired so far, the number of random numbers that can be acquired will decrease, and the random numbers acquired after the second will be used. As for the control process to be executed, the probability that a result advantageous to the player is obtained increases. In the gaming machine described in Patent Document 1, using such a phenomenon, when a random number is acquired within the same period, the color of the lamp indicating the holding ball is changed to indicate that the probability is high. , Trying to increase the interest of players.

JP 2007-125258 A

  Here, for example, as a gaming machine, in a so-called slot machine having a plurality of reels having symbols arranged on the outer peripheral surface, various controls are performed at the time of detecting an operation to a start switch that triggers the rotation of the reels. In order to draw the processes individually, a plurality of random numbers are acquired. However, as in the gaming machine described in Patent Document 1, when a plurality of random numbers are acquired from one counter, the number of random numbers that can be acquired after the second counter decreases, and the probability varies. It will end up. If the probability per random number fluctuates in this way, when designing the winning probability of each control process, the design is performed assuming that the probability fluctuates and does not fluctuate. There is a problem that it becomes complicated.

  Further, in order to suppress the fluctuation of the probability per random number, for example, if only one random number is acquired from one counter within the same period, and the random number is used for lottery in various control processes, production etc. There is a problem that the control process is likely to be monotonous, and further, for example, when a loop lottery or the like is executed, a result of continuous winning will be generated, so that there is a problem that a process such as a loop lottery cannot be adopted. .

  Accordingly, an object of the present invention is to provide a gaming machine capable of acquiring a plurality of random numbers whose probability per random number does not vary without using a random number used once.

(1) The present invention has a first number of storage areas (114a, 114b, 115a, 115b, 116a, 116b) for storing random numbers, and random number generation counters (111, 112, 113) at predetermined intervals. ) Random number generation means (110) for updating the random number stored in the storage area by overwriting and saving the random number acquired from the storage area;
A determination means (180) for acquiring a random number stored in the storage area, executing a control process for referring to and comparing a data table based on the acquired random number, and determining based on a result of the executed control process ; With
The determination means includes
When acquiring a plurality of random numbers to execute the control process within the predetermined interval, the random number stored in the storage area that has already been acquired is not acquired,
When the number of random numbers acquired in the control process is a second number larger than the first number, a random number is acquired from a specific storage area (114b) among the plurality of storage areas during the execution of the control process. when, until judged as the process before Symbol number generating means updates the random number is executed to wait for the progress of the control process waiting to acquire a random number, characterized in that.

  (2) Further, in the gaming machine according to the present invention, the determination means sequentially acquires the plurality of storage areas when acquiring a plurality of random numbers.

  For this reason, the gaming machine of the present invention acquires random numbers from a specific storage area after acquiring each of the random numbers stored in the plurality of storage areas at the time of execution of the control process using the plurality of random numbers by the determination means. At this time, since the random number generation unit waits for the random number to be updated, it is possible to reduce the number of times to wait for the acquisition of the random number and prevent the execution of the control process from being delayed.

( 3 ) Further, in the gaming machine of the present invention, the random number generation means has a plurality of random number generation counters (111, 112, 113) for generating random numbers,
The random number is stored in each of the plurality of storage areas using a counter random number generated only once from each of the plurality of random number generation counters within the predetermined interval.

  For this reason, the gaming machine of the present invention stores random numbers in each storage area using a counter random number generated only once from each random number generation counter within a predetermined interval, and therefore stores random numbers in each of the plurality of storage areas. In this case, random numbers whose probability per random number does not vary can be stored.

( 4 ) In the gaming machine of the present invention, the random number generation means divides the counter random number generated from the random number generation counter into the random number and stores it in the storage area.

  For this reason, the gaming machine of the present invention can store a plurality of random numbers without increasing the random number generation counter by storing the divided random number of the counter generated from the random number generation counter in the storage area as a random number. It is possible to reduce the capacity of random number generation means necessary for generating random numbers.

  According to the present invention, it is possible to provide a gaming machine capable of acquiring a plurality of random numbers whose probability per random number does not vary without using a random number used once.

Each means constituting the game control means 100 reads and executes each control program stored in advance in the storage means 190 when executing each control process. In addition, the game control means 100 executes interrupt processing at predetermined intervals (for example, about 1.5 ms) when each means constituting the game control means 100 is executing control processing. In the interrupt process, a backup acquisition process for dealing with an unexpected power interruption and a random number update process for updating a random number stored in the random number generation unit 110 described later are executed.

  The insertion accepting means 105 performs a process of validating the game start operation for the start lever SL based on the insertion of medals corresponding to the prescribed number of insertions (3) during the insertion acceptance period for accepting the insertion of medals. . Specifically, when a medal is inserted into the medal insertion slot MI, the insertion accepting unit 105 puts the inserted medals into the insertion state with the specified number of insertions as the limit in accordance with the operation of the medal insertion switch 210. Set. In addition, when the bet operation in which the single bet button BT or the max bet button MB is pressed in a state where the medal is credited is performed, the insertion accepting unit 105 performs the specified number of insertions as the bet switch 220 is activated. The credited medal is set to the inserted state with the limit of.

  In the slot machine 1 of the present embodiment, the first depressing operation of the start lever SL that is activated based on the insertion of medals corresponding to the predetermined number of insertions is accepted as the game start operation by the player, It is an opportunity to start the rotation of the reels R1 to R3, and an internal lottery means 120 described later is an opportunity to execute an internal lottery.

  The random number generation means 110 is a means for generating a random number acquired by each means in a control process executed by each means constituting the game control means 100. FIG. 3 is a diagram showing details of the random number generation means 110.

  As shown in FIG. 3, the random number generation means 110 has a first random number generation counter 111, a second random number generation counter 112, and a third random number generation counter 113 as a plurality of hardware counters for generating random numbers. ing. The first random number generation counter 111 to the third random number generation counter 113 are each configured by an increment counter (a counter that counts numerical values so as to circulate through a predetermined count range). In the present embodiment, the first random number generation counter 111 to the third random number generation counter 113 are configured to circulate in a range of 65536 values from 0 to 65535, respectively, and generate a 2-byte random number as a random number. The random number generation means 110 includes a first random number storage unit 114, a second random number storage unit 115, a third random number storage unit 116, which correspond to each of the first random number generation counter 111 to the third random number generation counter 113, have.

  The random number generation means 110 stores the random number generated from the first random number generation counter 111 in the first random number storage unit 114 capable of storing a 2-byte random number. When storing random numbers in the first random number storage unit 114, the random number generation unit 110 stores the upper 1 byte of the random number in the first upper byte 114a and stores the lower byte of the random number in the first lower byte 114b. In the initial state, the first random number storage unit 114 stores a value “0” in each of the first upper byte 114a and the first lower byte 114b.

  Also, in the first random number storage unit 114, each unit constituting the game control unit 100 acquires the random number stored in the first upper byte 114a among the random numbers stored in the first random number storage unit 114. In order to cope with the case where the random number stored in the first lower byte 114b is acquired, each means constituting the game control means 100 identifies the first upper byte 114a and the first lower byte 114b. An identification pointer is set. As shown in FIG. 3, the identification pointer of the first lower byte 114b is set to “0”, and the identification pointer of the first upper byte 114a is set to “1”.

  The random number generation means 110 stores the random number generated from the second random number generation counter 112 in the second random number storage unit 115 capable of storing a 2-byte random number. When storing random numbers in the second random number storage unit 115, the random number generation means 110 stores the upper 1 byte of the random number in the second upper byte 115a and the lower byte of the random number in the second lower byte 115b. In the initial state, the second random number storage unit 115 stores the value “0” in each of the second upper byte 115a and the second lower byte 115b.

  The second random number storage unit 115 obtains a random number stored in the second upper byte 115a among the random numbers stored in the second random number storage unit 115 by each unit constituting the game control unit 100. In order to respond to the case where the random number stored in the second lower byte 115b is acquired, each means constituting the game control means 100 is for identifying the second upper byte 115a and the second lower byte 115b. An identification pointer is set. As shown in FIG. 3, “2” is set for the identification pointer of the second lower byte 115b, and “3” is set for the identification pointer of the second upper byte 115a.

  The random number generation means 110 stores the random number generated from the third random number generation counter 113 in the third random number storage unit 116 capable of storing a 2-byte random number. When storing random numbers in the third random number storage unit 116, the random number generation means 110 stores the upper 1 byte of the random number in the third upper byte 116a, and stores the lower byte of the random number in the third lower byte 116b. In the initial state, the third random number storage unit 116 stores the value “0” in the third upper byte 116a and the third lower byte 116b.

  Further, in the third random number storage unit 116, each unit constituting the game control unit 100 acquires a random number stored in the third upper byte 116a among the random numbers stored in the third random number storage unit 116. In order to cope with the case where the random number stored in the third lower byte 116b is acquired, each means constituting the game control means 100 is for identifying the third upper byte 116a and the third lower byte 116b. An identification pointer is set. As shown in FIG. 3, the identification pointer of the third lower byte 116b is set to “4”, and the identification pointer of the third upper byte 116a is set to “5”.

  The random number generation means 110 performs the first random number generation counter 111 when the player performs a start operation on the start lever SL and a start signal output by the start switch 230 detecting the start operation is input. The random numbers generated from the third random number generation counter 113 are stored in the first random number storage unit 114 to the third random number storage unit 116. In addition, the random number generation unit 110 outputs the random numbers generated from the first random number generation counter 111 to the third random number generation counter 113 when the game control unit 100 executes the interrupt process, from the first random number storage unit 114 to the third random number storage unit 116. Execute random number update processing to update the random number.

  The details of the random number update process performed by the random number generation unit 110 when the interrupt process is executed will be described by taking as an example the case where the random number stored in the first random number storage unit 114 is updated with the random number generated from the first random number generation counter 111. . The random number generation means 110 adds the counter random number generated from the first random number generation counter 111 and the random number already stored in the first random number storage unit 114 when executing the interrupt process. When the added value is less than 65535, the random number generation unit 110 stores the added value by dividing it into the first upper byte 114a and the first lower byte 114b, thereby storing it in the first random number storage unit 114. Update random numbers. On the other hand, when the added value is 65536 or more, the random number generation means 110 divides the result obtained by subtracting 65536 from the added value into the first upper byte 114a and the first lower byte 114b, and stores the result. The random number stored in the 1 random number storage unit 114 is updated.

  By executing the random number update process, the random number generation unit 110 can update the random number stored in the first random number storage unit 114 and store a new random number in the first random number storage unit 114.

  Further, by dividing the counter random number generated from the first random number generation counter 111 into the first upper byte 114a and the first lower byte 114b, the random number generation means 110 can convert the random number used in the control processing into the hardware. A plurality of accounts can be stored without increasing the account, and the capacity of the random number generation means 110 necessary for generating random numbers can be reduced.

  Note that the random number generation unit 110 also updates the random numbers stored in the second random number storage unit 115 and the random numbers stored in the third random number storage unit 116. A random number update process similar to that for updating a random number stored in the one random number storage unit 114 is performed.

  Here, the first random number generation counter 111 to the third random number generation counter 113 are increment counters that circulate in a range of 65536 values from 0 to 65535, respectively, as described above. In the first random number generation counter 111 to the third random number generation counter 113 of this embodiment, the time required to reach 0 to 65535 is shorter than the interrupt processing cycle. That is, the random number generation means 110 includes the counter random number generated from the first random number generation counter 111 to the third random number generation counter 113 at the time of execution of the previous interrupt process and the first random number generation counter 111 to the first number of times at the time of execution of the current interrupt process. The counter random number generated from the three random number generation counter 113 is configured not to be a random number generated within the same period.

  Therefore, the random number generation unit 110 uses the counter random number generated only once from each of the first random number generation counter 111 to the third random number generation counter 113 within the interval at which the interrupt process is executed. In order to store random numbers in the first to third upper bytes 114a to 116a and the first to third lower bytes 114b to 116b of the 114 to third random number storage unit 116, when storing random numbers in the upper bytes and the lower bytes, respectively. In the same period until the random number circulates, a plurality of random numbers are not acquired, and a random number whose probability per random number does not vary can be stored. The first to third upper bytes 114a to 116a and the first to third lower bytes 114b to 116b in which random numbers generated from the first random number generation counter 111 to the third random number generation counter 113 are stored are used in the present embodiment. Configure multiple storage areas.

  In the present embodiment, the “random number” is not limited to a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, the acquisition timing and the like are substantially irregular. Values that can function as random numbers are also included.

  The internal lottery means 120 is a means for performing an internal lottery for determining whether or not a winning combination is made based on the input of a start signal output from the start switch 230. The lottery table selection process, random number determination process, lottery flag Perform setting processing.

  In the lottery table selection process, the internal lottery table stored in the internal lottery table storage unit 191 of the storage unit 190 is selected based on the current gaming state to use the internal lottery table. To do.

  In each internal lottery table, each of a plurality of random numbers (for example, 65536 random numbers from 0 to 65535) is associated with various combinations such as replays, small roles, bonuses, and losing. . Here, an internal lottery table (hereinafter referred to as “internal lottery table A”) selected when the gaming state is the normal state, and an internal lottery table (hereinafter referred to as “internal lottery table A”) selected when the gaming state is the bonus establishment state. , Described as “internal lottery table B”), the winning probabilities of the small roles are set to be the same, and as the small roles, a plurality of types of bells are paid out in which more medals are paid out than the prescribed number of inserted coins when winning. A random number corresponds to each of the winning combinations and a plurality of types of missing combinations that can be awarded when the timing of pressing the stop button B1 to the stop button B3 is appropriate while paying out medals less than the prescribed number of coins inserted at the time of winning. It is attached. Also, in the slot machine 1 of the present embodiment, a big bonus (hereinafter referred to as “BB”) as a bonus continuous operating device related to the first type special bonus is prepared as a bonus. , BB is set as a lottery target. The internal lottery table B is different from the internal lottery table A in the replay win probability, and the replay win probability is higher than the internal lottery table A by making the replay a lottery instead of BB and lose in the internal lottery table A Is set to be high. An internal lottery table (hereinafter referred to as “internal lottery table C”) that is selected when the gaming state is a bonus establishment state, JAC1 that wins multiple types of bell roles as a small role, and multiple types A random number is associated with JAC2 which is won in duplicate for the missing combination.

  In the random number determination process, based on the start signal output from the start switch 230, a random number (random number for lottery) is selected from one of the first random number storage unit 114 to the third random number storage unit 116 of the random number generation unit 110 for each game. The acquired random number is compared with the internal lottery table selected in the lottery table selection process, and it is determined whether or not the winning combination is won based on the comparison result.

  In the lottery flag setting process, the lottery flag corresponding to the winning combination determined to be won based on the result of the random number determination process is changed from the non-winning state (first flag state, off state) to the winning state (second flag state). , ON state). In the slot machine 1 of the present embodiment, when two or more types of winning combinations are won, a lottery flag corresponding to each of the two or more types of winning winning combinations is set to a winning state. The lottery flag setting information is stored in the lottery flag storage unit 192 of the storage unit 190.

  Here, in the slot machine 1 according to the present embodiment, a lottery flag (carry-over possible flag) that can carry on the winning state for the next game until winning, and a winning state are carried over for the next game regardless of the winning. A lottery flag (a carry-over impossible flag) that is reset to a non-winning state is prepared. BB is associated with the former carry-over possible flag, and the small combination and replay are associated with the latter carry-over impossible flag. That is, in the lottery flag setting process, when BB is won by internal lottery, a process of carrying over the winning state of the lottery flag of BB until BB wins is performed. At this time, the internal lottery means 120 performs an internal lottery that determines whether or not the small role and replay are successful even in a game in which the winning state of the BB lottery flag is carried over. In other words, in the lottery flag setting process, in a game in which the winning state of the BB lottery flag is carried over, if a small role or replay is won, the BB lottery flag already won and the small lot won by the internal lottery A lottery flag corresponding to two or more types of combinations including a combination and a replay lottery flag is set in a winning state.

  The reel control means 130 is driven by the first reel R1 to the third reel R3 by the stepping motor based on the output of the start signal from the start switch 230 that operates when the player performs a start operation on the start lever SL. The rotation drive of is started. In addition, the reel control means 130, when the rotation state of the first reel R1 to the third reel R3 is a rotation state in which the rotation is a steady rotation at a predetermined speed (for example, about 80 rpm), the stop button B1 corresponding to each reel. Control for enabling the stop operation detected by the stop switch 240 when the stop button B3 is pressed is executed. The reel control means 130 stops supplying the drive pulse (motor drive signal) to the stepping motor of the reel unit 310 when the reel stop signal is output from the stop switch 240 based on the detection of the stop operation. Then, control is performed to stop each of the first reel R1 to the third reel R3. At this time, the reel control unit 130 performs control to stop the first reel R1 to the third reel R3 that are rotationally driven by the stepping motor in a manner corresponding to the lottery flag setting state, that is, the result of the internal lottery. That is, the reel control means 130 determines the stop position of the reel corresponding to the pressed stop button among the first reel R1 to the third reel R3 each time each of the stop buttons B1 to B3 is pressed. Thus, control is performed to stop the reel at the determined stop position.

  Further, in the slot machine 1 of the present embodiment, the first reel R1 to the third reel R3 are rotating corresponding to the pressed stop button within 190 ms from the time when the stop button B1 to the stop button B3 is pressed. The reel is stopped. Here, when the rotating reel is stopped within 190 ms from the time when the stop button is pressed, the reel is stopped from the time when the stop button is pressed based on the diameter and rotation speed of each reel. Up to 4 frames can be rotated up to this point. The reel control means 130 displays the symbol corresponding to the winning combination in the internal lottery on the outer peripheral surface of the rotating reel corresponding to the stop button that has been pressed among the stop buttons B1 to B3. The symbol corresponding to the combination for which the lottery flag is set to the winning state is valid when the position is within the range of 0 frame to 4 frames with respect to the display position on the active line L1 at the time when the operation is pressed. Control is performed to stop the rotating reel corresponding to the stop button on which the pressing operation has been performed so that the reel is displayed at the display position on the line L1.

  Here, the reel control means 130 receives the start signal output when the start switch 230 detects the start operation, starts the rotation of the first reel R1 to the third reel R3, and starts one game. In this case, a waiting time (about 4.1 seconds) generally called a wait (or wait time) is set. Then, when the reel control means 130 receives the start signal from the start switch 230 within the period from the setting of the standby time until the standby time elapses, the first reel R1 to the third reel R3 after the standby time has elapsed. Is configured to start rotation. With this configuration, the reel control means 130 can start a game after a minimum game time (about 4.1 seconds) has elapsed as a certain time from the start of one game to the start of the next game. .

  The reel control unit 130 refers to a logic calculation process for obtaining a stop position of the rotating reel by logic calculation and a stop control table stored in the stop control table storage unit 193 of the storage unit 190, so that the reel control unit 130 rotates. Table reference processing for determining the stop position is performed.

  First, in the logic calculation processing, 0 to 4 frames from the pressing detection position, which is the position of the reel at the time when the stop switch 240 is activated, that is, when the pressing operation of the stop button is detected according to the priority order data determined for each combination. Priorities are obtained for the stop position candidates for five frames existing in the range. Here, the reel control means 130 is a reel index which is information indicating that the reel output once has been rotated when the photo sensor provided in the reel unit 310 detects the reel position detection unit provided in each reel. And the rotation angle of the reel from the reference position at which the reel index is detected (calculated from the number of times of supply of the drive pulse supplied to the stepping motor), and the rotation state of the reel when the reel stop signal is received from the stop switch. get. Then, the stop position candidate with the highest priority among the priorities of the respective stop position candidates is determined as the actual stop position. However, in the logic calculation process, the same priority may be obtained for a plurality of stop position candidates depending on the result of the internal lottery, the pressed detection position, and the like. When there are a plurality of stop position candidates with the highest priority, the actual stop position is determined by table reference processing.

  In the slot machine 1 of this embodiment, the priority order is determined in the order of “replay> small role> bonus”. In the logic operation processing, when the lottery flags relating to two or more types of winning combinations are set to the internal winning state, the stop including the symbols constituting the winning form of the winning combination having the highest priority according to the priority order associated with each winning combination. The priority is determined so that the position candidate has a higher priority than the stop position candidate including the symbols constituting the winning form of the role having a low priority.

  Note that, in the slot machine 1 of the present embodiment, when a plurality of types of small roles are won in the internal lottery, the method of obtaining the priority of the stop position candidates depends on the number of symbol combinations that can be displayed on the active line L1. There are a method for obtaining the priority and a method for obtaining the priority according to the number of medals to be paid out based on a payout predetermined for the small role. In the case of obtaining the priority of the stop position candidates in accordance with the number of symbol combinations that can be displayed on the effective line L1, the symbol combination indicating the winning pattern that can be displayed on the effective line L1 (hereinafter, “winning symbol combination”). The priority of each stop position candidate is determined so that the priority becomes higher as the stop position increases in number. In addition, when the priority of the stop position candidates is obtained according to the number of medals paid out, the number of medals paid out based on the payout of the small role corresponding to the symbol displayed at the display position on the active line L1 is large. The priority of each stop position candidate is determined so that the higher the priority is, the higher the stop position becomes, that is, the stop position where a small combination with a large payout can be won. However, when determining the priority of stop position candidates according to the number of paid-out medals, if a small role with the same payout is won in duplicate, each of the small positions can be won. Candidate priorities are treated as the same.

  In the logic calculation process, so-called pull-in process and kick-out process are performed as processes for obtaining reel stop position candidates. Here, the pull-in process is a process of obtaining reel stop position candidates so that the winning combination whose lottery flag is set to the winning state can be won as much as possible. On the other hand, the kicking process is a process of obtaining reel stop position candidates so that a combination whose lottery flag is set to a non-winning state cannot be won. In this way, the reel control means 130 can stop the symbol of the combination for which the lottery flag is set to the winning state in a winning form, while the symbol of the combination for which the lottery flag is set to the non-winning state Logic calculation processing is performed to obtain reel stop position candidates so as not to stop at.

  The winning determination means 140 performs a winning determination process for determining whether or not a winning combination has been won based on the stop mode of the first reel R1 to the third reel R3. Specifically, referring to the winning determination table stored in the winning determination table storage means 194 of the storage means 190, the display is made on the active line L1 when all of the first reel R1 to the third reel R3 are stopped. It is determined whether or not the symbol combination that has been set is a predetermined winning combination. The winning combination is such that the presence / absence of a winning combination of BB, replay, bell, and spilling can be determined (hereinafter referred to as “winning determination”) based on the symbol combination displayed on the active line L1 in a state where each reel is stopped. A judgment table is prepared.

  In this embodiment, a plurality of types of bells can be won when the bells that can be won without fail depending on the pressing timing of the stop buttons B1 to B3 and when the pressing timings of the stop buttons B1 to B3 are appropriate. It may be any of the bell role. The symbols constituting the winning symbol combination of the bell role that can be won regardless of the pressing timing of the stop button B1 to the stop button B3, the first reel in a positional relationship that can be displayed on the effective line L1 regardless of the pressed detection position. R1 to the third reel R3 are arranged respectively. Similarly, the replay is configured so that a winning can be made regardless of the timing of pressing each stop button. On the other hand, when the BB and the stop button B1 to the stop button B3 are pressed at appropriate timings, the winning combination of the bell and the losing combination means that the symbols constituting the winning symbol combination of each winning combination are in the range of the number of sliding frames. The reels are arranged on the reels so that they are displayed on the effective line L1 when the stop buttons are operated to stop in the state of being located inside.

  And in the slot machine 1 of this embodiment, each process is performed based on the determination result of the winning determination means 140 in the winning determination process. As each process executed based on the winning combination determination result, for example, when a small combination wins, a process for determining the number of medals to be paid out to the payout control means 150 is performed, and when a replay wins. Causes the replay processing means 160 to execute processing without consuming medals in the next game, and when a bonus is won, processing to shift the gaming state to the gaming state transition control means 170 is performed.

  The payout control means 150 performs payout processing relating to the payout of medals according to the game result. Specifically, when a small combination wins, the number of medals to be paid out in the game is determined based on a predetermined payout for each combination, and a medal corresponding to the determined number of payouts is used as a payout device. Control to cause the hopper unit 320 to pay out is performed. In the present embodiment, the dividends for a plurality of types of bell combinations set to a number of payouts greater than the specified input number are all set to eight. In addition, the dividends of a plurality of types of missed combinations that are set to a number of payouts smaller than the specified number of inserts are all set to one.

  The replay processing means 160 determines that the symbol combination indicating the replay winning is stopped and displayed on the active line L1 by the winning determination means 140, and when the replay wins, the player inserts medals owned by the player for the next game. The replay process (re-game process) for setting the same preparation state as the previous game is performed without the need for. That is, in the slot machine 1 of the present embodiment, when a replay is won, an automatic insertion that automatically inserts the same number of medals as the previous game without using the player's own medals (including credit medals). Processing is performed, and the next start operation for the start lever SL is waited in a state where the same effective line L1 as that of the previous game is set.

  As shown in FIG. 4A, the gaming state transition control means 170 performs a gaming state transition control process for transitioning the gaming state among the normal state, the bonus establishment state, and the bonus state. Here, one condition may be defined as the game condition transition condition, or a plurality of conditions may be defined. In the case where a plurality of conditions are set, the game is based on the fact that any one of the plurality of predetermined conditions is satisfied, or that all of the plurality of predetermined conditions are satisfied. The state can be shifted to another gaming state. In the present embodiment, the gaming state transition control means 170 has a normal state, a bonus establishment state, and a bonus state as the gaming state, but is not limited to this, for example, a normal state or a bonus establishment state. You may have the replay time state (RT state) from which the winning probability of a replay differs, and you may have several RT state from which the winning probability of a replay each differs.

  The normal state is a game state corresponding to the initial state among a plurality of types of game states, and a transition from the normal state to the bonus establishment state is possible. Specifically, when the BB is won in the normal state, the state shifts to the bonus establishment state. Further, in the normal state, of the internal lottery table A to the internal lottery table C, refer to the internal lottery table A in which the winning probability of replay is set to about 1 / 7.3, for example, and BB is set as a lottery target. The internal lottery is performed.

  The bonus establishment state is a gaming state that shifts when the BB is won in the internal lottery. In the bonus establishment state, the internal lottery with reference to the internal lottery table B among the internal lottery table A to the internal lottery table C is performed. In the internal lottery table B, as described above, since BB is a winning combination associated with the carry-over possible flag, BB is excluded from the lottery target, and replay is the lottery target instead of BB. For this reason, the internal lottery table B is set to have a higher replay win probability than the internal lottery table A.

  In the bonus establishment state, as described above, the lottery flag corresponding to BB is maintained in the winning state until BB wins. When the winning symbol combination of BB is displayed on the active line L1, the gaming state transition control means 170 shifts the gaming state from the bonus establishment state to the bonus state.

  The bonus state is a gaming state that shifts when the winning symbol combination of BB is displayed on the active line L1. In the bonus state, an internal lottery is performed with reference to the internal lottery table C having a configuration in which the winning probability of the small role is different from the other internal lottery tables among the internal lottery tables A to C.

  In the bonus state, it is determined whether or not the end condition is satisfied based on the total number of medals paid out in the bonus state. The gaming state transition control means 170 performs control to end the bonus state and return the gaming state to the normal state when medals exceeding a predetermined number (for example, 100) are paid out. In the present embodiment, the end condition for the bonus state is determined by the total number of medals paid out. However, the end condition may be determined by the number of games in the bonus state or the number of wins for small roles. Further, the bonus state may be one in which an end condition is set so as to end in one game.

  The effect control means 180 is based on the effect data stored in the effect data storage means 195 and relates to effects related to the game, such as display effects performed using the display device 330 and sound effects performed using the audio device 340, for example. Control and control for causing the reel control means 130 to execute effects using the behavior of the first reel R1 to the third reel R3 are performed. Specifically, when the player operates the respective components of the slot machine 1 for the operation of the medal insertion, the single bet button BT, the maximum bet button MB, the start lever SL, the stop button B1 to the stop button B3, or the like When a game event such as a state change occurs, the first reel is turned on or blinking, the display content of the display device 330 is changed, the sound is output from the speaker, and the start signal is output from the start switch 230. By performing an effect using the first reel R1 to the third reel R3 that delays the start of rotation of the R1 to the third reel R3, an effect for exciting the game or an execution control for assisting the game is performed. .

  In the slot machine 1 of the present embodiment, the effect control means 180 changes the normal effect state, the chance zone state (CZ state), and the assist time state (AT state) as the special effect state, as shown in FIG. The production state is changed among a plurality of types of production states including the control, and the production state is controlled to shift to the CZ state or the AT state based on the establishment of a predetermined transition condition. Further, the effect control means 180 causes each component constituting the effect device 300 to execute an effect based on each effect state. In the present embodiment, the effect control unit 180 acquires a random number stored in any of the first random number storage unit 114 to the third random number storage unit 116 of the random number generation unit 110 for each lottery process using a random number. Each lottery process is executed using an effect lottery table necessary for each lottery process among the plurality of effect lottery tables stored in the effect lottery table storage unit 196.

  The normal effect state is an effect state that is executed when the effect state is not the CZ state or the AT state, and is an effect state that continues until the state is shifted to another effect state. In the normal performance state, the performance control means 180 executes a CZ lottery that determines by lottery whether or not to shift to the CZ state when a predetermined winning combination determined in advance is won. Further, in the normal production state, the production control means 180 executes an AT lottery that determines whether or not to shift to the AT state when a specific winning combination different from the predetermined winning combination is won.

  The CZ state is an effect state in which the effect state is the normal effect state, and the transition is made when the CZ lottery is won in the normal effect state. In the CZ state, the effect control unit 180 sets a value (for example, 10 games) corresponding to a predetermined number of games in the CZ end determination counter 197 at the start of the CZ state, and determines whether or not to shift to the AT state for each game. It is configured to execute an AT lottery for lottering, and it becomes an effect state in which it is easier to shift to the AT state than the normal effect state in which the AT lottery is executed only when a predetermined winning combination is won. Yes. When the AT lottery is won, the effect control means 180 changes the effect state from the CZ state to the AT state. In addition, the effect control unit 180 executes the game for a preset number of games (for example, 10 games) without winning the AT lottery, and when the stored value of the CZ end determination counter 197 becomes 0, the CZ The production state is shifted from the state to the normal production state, and the CZ state is terminated.

  The AT state shifts between a case where an AT lottery executed in the normal performance state and the CZ state is won and a case where a predetermined number of games (for example, 1000 games) are executed without shifting to the AT state. It is a production state. In the AT state, the effect control means 180 has a stop button B1 that can win the bell role in the game information display section DS when winning the bell role that can be won when the pressing timing of the stop buttons B1 to B3 is appropriate. ~ A display indicating the pressing timing of the stop button B3 is executed, and as an effect of notifying that the bell role is won, for example, by displaying the winning symbol combination constituting the bell role on the display device 330, The stage effect device 300 is caused to perform a winning assistance effect that assists in winning a prize indicating a pressing timing at which a bell role can be won. For this reason, the AT state is an effect state that is advantageous for paying out medals for a player who can easily acquire medals.

  In addition, when the number of games set at the start of the AT state (for example, 50 games) is executed, the effect control unit 180 shifts the effect state from the AT state to the normal effect state and ends the AT state. . In the present embodiment, the AT state is any of the case where the normal state is shifted, the case where the state is shifted from the CZ state, and the case where the game is transferred after 1000 games are executed without shifting to the AT state. Even in this case, the same value (50 games) is set as the number of AT games set in the AT end determination counter 198 at the start of the AT state. The values set in the AT end determination counter 198 may be different from each other. When configured in this manner, the slot machine 1 changes the number of times the benefit of the AT state can be enjoyed according to the AT state transition opportunity, so that the player can select which transition opportunity is to be established, The interest in games can be improved.

  In addition, the effect control means 180 performs a stop operation on the reel control means 130 based on a start signal output when the player performs a start operation on the start lever SL and the start switch 230 detects the start operation. In the period until the detection of the stop operation by 240 is validated, a freeze that temporarily delays the progress of the normal game is generated, and the first reel R1 to the third reel R3 are specified in the reel control means 130 It is comprised so that the reel production | presentation operated by the aspect can be performed. When the effect control unit 180 determines whether or not to execute the reel effect, for example, whether or not to execute the reel effect by a lottery executed based on the input of the start signal output from the start switch 230. You may decide. Further, the effect control means 180 may be configured to execute a reel effect when a condition such as when a specific winning combination is established. The effect control means 180 in the present embodiment has a reel lock effect that generates a freeze and delays the start of rotation of the first reel R1 to the third reel R3 as a reel effect.

  Note that the functional block configuration of the present embodiment can also be applied to a computer system (including a game system). In these systems, the function is realized by downloading a program that causes the computer to function as the game control means 100 of the present embodiment from an information storage medium such as a CD or DVD or a Web server on the Internet via a network. be able to. Further, in the above computer system, the medal insertion switch 210, the bet switch 220, the start switch 230, the stop switch 240, and the like virtually function their functions with respect to operation means such as a keyboard, a pointing device (mouse, etc.), or a controller. This can be realized by assigning to In the computer system, the reel unit 310, the hopper unit 320, and the like are not essential constituent requirements. These device units can virtually realize their functions by controlling images displayed on the display (display device 330).

2. Next, referring to FIG. 5 to FIG. 7, in the slot machine 1 according to the present embodiment, when the effect control means 180 executes a reel lock effect as a reel effect. Each processing to be executed and processing related to update of the random number executed by the random number generation unit 110 in the interrupt processing will be described.

<Reel lock effect processing>
FIG. 5 shows a reel lock effect process executed when the effect control means 180 decides to execute the reel lock effect as the reel effect in the slot machine 1 in the present embodiment. As described above, the effect control unit 180 of the present embodiment is set in advance, for example, when it is determined to execute the reel lock effect by lottery executed based on the input of the start signal output from the start switch 230. When the conditions for executing the reel lock effect are satisfied, the reel lock effect process shown in FIG. 5 is executed by generating a freeze and delaying the progress of the game.

First, the effect control means 180 adds 1 to the lottery counter (not shown) in the storage means 190 (S1). In this process, the effect control means 180 performs steps S2 and S3 described later.
1 is added to a lottery counter that stores the number of times that the continuous lottery process for determining whether or not to extend the time for continuing the reel lock effect to be performed is performed.

  Next, the effect control means 180 performs a random number acquisition process (S2). In this process, the effect control unit 180 acquires a random number from the random number generation unit 110. In the present embodiment, the effect control means 180 is 1 byte among the random numbers stored in any of the first random number storage unit 114 to the third random number storage unit 116 included in the random number generation unit 110 in the process of step S2. For example, when a random number is acquired from the first random number storage unit 114, the random number stored in the first upper byte 114a and the first lower byte 114b are stored. Get random number from either random number or

  Next, the effect control means 180 compares the acquired random number with the continuation determination table stored in the effect lottery table storage means 196 of the storage means 190 (S3). In this process, the effect control unit 180 compares the random number acquired in step S2 with the continuation determination table that is a data table stored in the effect lottery table storage unit 196. Here, the continuation determination table is a data table in which continuation (winning) or end (non-winning) of the reel lock effect is associated with each of the random numbers 0 to 255.

  Next, the effect control means 180 determines whether or not the continuation of the reel lock effect is won (S4). In this process, the effect control means 180 determines whether or not the acquired random number is a random number associated with continuation of the reel lock effect in the continuation determination table, and is a random number associated with continuation of the reel lock effect. If yes (YES), 1 second is added to the reel lock duration time for executing the reel lock effect (S5), and the process returns to step S1.

  On the other hand, when the acquired random number is associated with the end of the reel lock effect (NO), the effect control unit 180 determines whether the stored value of the lottery counter is less than 7 (S6). . In this process, when the effect control means 180 determines that the stored value of the lottery counter is less than 7 (YES), the number of executions of the continuous lottery process is less than 7, so the process proceeds to step S1. To return. As described above, the effect control means 180 is configured to execute the continuous lottery process at least seven times when the reel lock effect is executed. That is, the effect control means 180 of this embodiment is configured to acquire at least seven random numbers when executing the reel lock effect process.

  In the process of step S6, when it is determined that the stored value of the lottery counter is 7 or more (NO), the effect control means 180 determines whether the reel lock duration time is less than 5 seconds (S7). ). In this process, when it is determined that the reel lock duration time is less than 5 seconds (YES), the effect control means 180 sets the reel lock duration time to 5 seconds (S8). By executing the processes of steps S7 and S8, the effect control unit 180 can cause the reel control unit 130 to execute the reel lock effect for at least 5 seconds, and allow the player to recognize the reel lock effect.

  After performing the process of step S8 or in the process of step S7, if it is determined that the reel lock duration is 5 seconds or more (NO), the effect control means 180 executes the reel lock effect to the reel control means 130. (S9). Next, the effect control means 180 executes various processes accompanying the execution of the reel lock effect (S10), and ends the reel lock effect process. In this process, the effect control means 180 executes, for example, a process for determining a privilege to be given to the player based on the reel lock duration time, a process for ending the freeze after the reel lock effect ends.

  In this way, random numbers are acquired from the first to third upper bytes 114a to 116a and the first to third lower bytes 114b to 116b of the first random number storage unit 114 to the third random number storage unit 116, and based on the acquired random numbers. The reel lock effect process that executes the processes of steps S2 and S3 with reference to the continuation determination table constitutes a control process in the present embodiment. Further, the effect control means 180 for determining the result of the control process in steps S2 and S3 in the process in step S4 constitutes a determination means in the present embodiment.

<Random number acquisition processing>
FIG. 6 is a flowchart showing the random number acquisition process executed in step S2 of the reel lock effect process shown in FIG.

  First, the effect control means 180 sets an address for storing a random number (S21). In this process, the effect control unit 180 sets an address for temporarily storing the acquired random number, and stores the random number at the address set in the process of step S21 when the random number is acquired in the subsequent process. In addition, the effect control means 180 compares the random number stored in the address with the continuation determination table in the processing of step S3 shown in FIG.

  Next, the effect control means 180 updates the random number acquisition pointer (S22). In this process, the effect control unit 180 executes a pointer update process for adding 1 to the value of the random number acquisition pointer that identifies the storage area in which the random number to be acquired is stored. In the present embodiment, “0” is set as the initial value of the random number acquisition pointer. The effect control means 180 updates the value of the random number acquisition pointer to “1” by the process of step S22 when the first random number acquisition process is executed. The random number acquisition pointer corresponds to the identification pointer of the random number generation means 110 described above, and is configured such that the value circulates in the range of 0 to 5. Therefore, the effect control unit 180 updates the value of the random number acquisition pointer to “0” when executing the process of step S22 in a state where the value of the random number acquisition pointer is “5”.

  Next, the effect control means 180 determines whether or not the value of the random number acquisition pointer is “0” (S23). In this process, when it is determined that the value of the random number acquisition pointer is “0” (YES), the effect control unit 180 determines whether or not the interrupt process is executed (S24), and the interrupt process is executed. If it is determined that it has not been performed (NO), the process of step S24 is repeated.

  In the process of step S24, the effect control means 180 has executed the interrupt process by repeating the process of step S24 until the same time as the cycle of executing the interrupt process elapses after the process of step S24 is started. It is configured to determine whether or not. Note that the game control means 100 may be configured to output a signal indicating that the interrupt process has been executed to the effect control means 180 when the interrupt process is executed. When configured in this way, the effect control unit 180 can shift from the process of step S24 to the process of step S25 immediately after execution of the interrupt process.

  If it is determined in step S23 that the value of the random number acquisition pointer is not “0” (NO), or if it is determined in step S24 that interrupt processing has been executed (YES), the effect control means 180 Acquires a random number from the storage area corresponding to the random number acquisition pointer (S25), stores the acquired random number in the address set in the process of step S21 (S26), and ends the random number acquisition process. In the process of step S25, the effect control unit 180 stores the first random number storage unit 114 to the third random number storage unit 116 included in the random number generation unit 110 in a storage area having the same identification pointer value as the random number acquisition pointer value. Get the stored random number.

  Thus, in the present embodiment, the effect control unit 180 updates the random number acquisition pointer every time the random number acquisition process is performed by the process of step S22. As described above, the effect control means 180 executes the random number acquisition process at least seven times in order to acquire at least seven random numbers in the reel lock effect process (see FIG. 5). In other words, the production control means 180 performs the first higher byte 114a, the first lower byte 114b, the second upper byte 115a, the second lower byte 115b, A plurality of storage areas of the three upper bytes 116a and the third lower bytes 116b are sequentially looped and acquired.

  In the present embodiment, the effect control means 180 executes the processes of steps S23 and S24 when acquiring a random number from the first lower byte 114b in which the identification pointer is set to “0” as a specific storage area. The acquisition of the random number is waited until the update of the random number is executed by the interrupt process.

  Therefore, the effect control means 180 does not acquire the random number stored in the already acquired storage area and stores the random number stored in the first lower byte 114b when executing the reel lock effect process for acquiring a plurality of random numbers. When the random number is acquired, the reel lock effect processing can be executed without using the random number once used by waiting for the random number generation unit 110 to wait until the random number is updated. It is possible to obtain a plurality of random numbers that do not vary in probability.

  In addition, the effect control unit 180 acquires random numbers from the first lower-order byte 114b of the first random number storage unit 114 after acquiring each of the random numbers stored in the first random number storage unit 114 to the third random number storage unit 116. In order to wait for the random number generation means 110 to update the random number, the random number can be acquired without executing the process of step S24 when the random number is acquired from other than the first lower byte 114b. It is possible to reduce the number of times of waiting and to prevent the execution of the reel lock effect process from being delayed.

  The effect control means 180 prepares the random number generation means 110 with the number of storage areas corresponding to the number of random numbers (seven or more) necessary for the reel lock effect processing by executing the processes of steps S23 and S24. The number of storage areas corresponding to the random numbers acquired by the effect control means 180 prepared in the random number generation means 110 (first upper byte 114a, first lower byte 114b, second upper byte 115a, second lower byte 115b, Control processing that requires more random numbers than the third upper byte 116a and the third lower byte 116b) can be executed, and the capacity of the random number generation means 110 can be reduced.

  Further, the slot machine 1 acquires the random number updated by the random number generation unit 110 when the effect control unit 180 acquires a larger number of random numbers than the number of storage areas prepared in the random number generation unit 110. There is no dependency between the random numbers, and the probability per random number does not vary. For this reason, in the slot machine 1, when creating the continuation determination table, the continuation determination table having the same probability of winning or not winning in each lottery without considering the dependency between random numbers and the fluctuation of the probability per random number. This makes it easy to create a data table and a program related to reel lock effect processing.

  In the present embodiment, the number of random numbers required for the reel lock effect process constitutes the second number, and the number of storage areas corresponding to the random number acquired by the effect control means 180 constitutes the first number.

<Random number update processing>
FIG. 7 is a flowchart showing a random number update process executed by the random number generation means 110 among the interrupt processes executed by the game control means 100 in the slot machine 1 according to the present embodiment. As described above, the random number generation unit 110 of the present embodiment is stored in the first random number storage unit 114 to the third random number storage unit 116 in the interrupt process executed at predetermined intervals (for example, about 1.5 msec). Execute random number update process to update existing random numbers.

  First, the random number generation means 110 acquires a counter random number generated from the first random number generation counter 111 (S31). Next, the random number generation unit 110 updates the first random number storage unit 114 by adding the counter random number acquired in step S31 and the random number stored in the first random number storage unit 114 (S32). As described above, when the added value is 65536 or more, the random number generation unit 110 stores the result of subtracting 65536 from the added value by dividing it into the first upper byte 114a and the first lower byte 114b. The first random number storage unit 114 is updated.

  Next, the random number generation means 110 acquires the counter random number generated from the second random number generation counter 112 (S33). Next, the random number generation unit 110 updates the second random number storage unit 115 by adding the counter random number acquired in step S31 and the random number stored in the second random number storage unit 115 (S34). As described above, when the added value is 65536 or more, the random number generation unit 110 stores the result obtained by subtracting 65536 from the added value by dividing it into the second upper byte 115a and the second lower byte 115b. The second random number storage unit 115 is updated.

  Next, the random number generation means 110 acquires the counter random number generated from the third random number generation counter 113 (S35). Next, the random number generation unit 110 updates the third random number storage unit 116 by adding the counter random number acquired in step S31 and the random number stored in the third random number storage unit 116 (S36), The random number update process is terminated. As described above, when the added value is 65536 or more, the random number generation unit 110 stores the result of subtracting 65536 from the added value in the third upper byte 116a and the third lower byte 116b, thereby The random number storage unit 116 is updated.

  As described above, the slot machine 1 according to the present embodiment does not acquire the random number stored in the storage area that has already been acquired at the time of execution of the reel lock effect process in which the effect control unit 180 acquires a plurality of random numbers. When the random number stored in the first lower byte 114b is acquired, the reel lock effect processing is performed without using the random number used once by waiting for acquisition of the random number until the random number is updated by the random number generation means 110. A plurality of random numbers that can be executed and whose probability per random number does not vary can be acquired.

3. Modified Example In the present embodiment, the reel control effect process by the effect control unit 180 has been described as an example. However, the present invention is not limited to this, and when the control process that requires a plurality of random numbers is performed, The present invention can be applied even when any control processing is executed. In addition, the present invention can be applied even when the second number of random numbers is used by each of the units constituting the game control unit 100 executing a lottery process.

  Specifically, for example, in a slot machine having a plurality of types of CZ states (first CZ state to third CZ state) as the CZ state and a plurality of types of AT states (first AT state to third AT state) as the AT state. When the internal lottery unit 120 executes the internal lottery, when the production control unit 180 executes the first CZ lottery for lottering whether or not to shift from the normal production state to the first CZ state, and the production control unit 180. When the second CZ lottery for lottering whether or not to shift from the normal performance state to the second CZ state is executed, and the third CZ lottery for lottery whether or not the effect control means 180 shifts from the normal performance state to the third CZ state When performing the first AT lottery for drawing whether or not the effect control means 180 shifts from the normal effect state to the first AT state, and the effect control means 180 When executing the second AT lottery for lottering whether or not to shift from the normal performance state to the second AT state, and the third AT lottery for lottering whether or not the effect control means 180 shifts from the normal performance state to the third AT state. When performing, when the production control means 180 executes the CZ lottery, and when the production control means 180 executes the reel lock production lottery to draw whether or not the reel lock production is executed, In each of the lottery processes, the present invention is applied even to a slot machine that obtains a random number from any one of the first to third upper bytes 114a to 116a and the first to third lower bytes 114b to 116b. Can do.

  In the present embodiment, the effect control unit 180 is configured to update each time the random number acquisition process (see FIG. 6) is performed without initializing the random number acquisition pointer. The random number acquisition pointer may be initialized when a start signal is input from the start switch 230.

  Further, in the present embodiment, the random number generation means 110 is configured to include the 2-byte first random number storage unit 114 to the third random number storage unit 116, but the number of storage areas is not limited to this. The random number generation means 110 only needs to have a storage area corresponding to the number of random number generation counters.

  Further, in the present embodiment, the slot machine 1 adopts the BB of the first type special bonus as a bonus state, but is not limited to this, for example, the challenge bonus (CB) of the second type special bonus. It may be adopted. In this case, it is necessary to configure so that the expected value for medal acquisition in the CB state is 100% or more.

  In the present embodiment, the slot machine 1 has been described as an example of a gaming machine. However, the present invention is not limited to this, and the present invention is applied to a so-called pachinko gaming machine in which a pachinko ball rolls on a gaming board. obtain.

  In the present embodiment, the slot machine 1 is configured to have the game control means 100 as a control board, but is not limited thereto, and for example, has a main control board and a sub control board as control boards. It may be configured. When configured in this manner, the slot machine 1 has control means for executing lottery processing and reel control related to the progress of games such as internal lottery on the main control board, and so-called AT as control processing related to effects. Each sub-control board may be provided with each control means for executing a control process including whether to win or not and lottery related to AT.

  In the present embodiment, the effect control unit 180 executes an interrupt process when acquiring a random number from the first lower byte 114b set to the identification pointer “0” corresponding to the random number acquisition pointer “0”. Although an updated random number can be acquired by acquiring a random number from the first lower byte 114b after the same time as the period has elapsed, the present invention is not limited to this. The effect control means 180 has, for example, a counter in which the initial value is set to 0 and the number of times of random number acquisition is stored by adding each time a random number is acquired. In this case, the control process may be delayed until the same time as the period in which the interrupt process is executed elapses. When configured in this way, the effect control means 180 uses all of the random numbers stored in the first random number storage unit 114 to the third random number storage unit 116 without setting the identification pointer, and then performs a random number update process ( The random number updated by (see FIG. 7) can be acquired, and the capacity of the random number generation means 110 can be reduced.
