Abstract

PROBLEM TO BE SOLVED: To provide a game machine making a player have expectation to a so-called lucky machine by imparting a benefit of time shortening processing to the player of the lucky machine with a simple configuration.SOLUTION: In a Pachinko machine, one of a "state A", a "state B", and a "state C" that are each in a time shortening-equipped probability variation state is executed as a game state after a jackpot based on a game state and a special symbol random number in time of jackpot state decision. After the time shortening processing is executed at a maximum frequency (300 times) or when a variation frequency of special symbols has reached 300 times or above, a "normal state" is executed as the game state after the jackpot. When the jackpot has reached the "normal game state", the "state A" where the benefit of the time shortening processing most advantageous to the player as the game state after the jackpot is imparted is selected.

Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine that can generate a gaming state advantageous to a player and is not successful even though a lot of gaming balls have won. The present invention relates to a gaming machine capable of giving a sense of expectation.

  Conventionally, in a pachinko machine, which is a type of gaming machine, a special symbol display unit that can display a special symbol on a gaming board is provided, and a special symbol is displayed on the special symbol display unit by winning a prize at the special symbol starting port of the game ball. Is displayed in a variable manner and then stopped to indicate whether or not it is a big hit. When a predetermined jackpot symbol is displayed, a jackpot state in which the player can acquire a large number of game balls is generated. In addition, when a normal symbol display part is provided on the game board and a normal winning symbol is displayed on the normal symbol display part, the movable piece of the special symbol start opening is opened for a predetermined time, so that the game ball becomes easier to win. A normal hit state is generated.

  And in the conventional pachinko machine, it is known to enhance the interest of the game by changing the game state after the big hit state. For example, in the first type of pachinko machines that are currently mainstream, special symbol display such as variation display of jackpot lottery results by a symbol matching game using two types of symbols, probability variation symbols and normal symbols If the jackpot lottery is determined to be a jackpot, the jackpot state is executed. It is known to control the game state such as “normal state”, “probability variation state”, “short time state”, etc. after the jackpot state is ended according to the jackpot symbol displayed in the symbol matching game.

  Here, the “normal state” is a default gaming state in which a predetermined standard value is set as a probability (hit probability) determined to be a big hit by a big hit lottery. Further, the “probability variation state” is a gaming state advantageous to a player in which a high probability that is a higher probability than the normal state is set as the jackpot probability. Note that the “short-time state” is a game state advantageous to the player, in which the short-time process is executed in which the symbol display time of the normal symbol display portion is shortened and the opening time of the movable piece of the special symbol start port is lengthened. is there.

  As described above, in the conventional pachinko machine, it is known that a game state (hereinafter referred to as a “hit after jackpot game state”) executed after the end of the jackpot state is set to correspond to the jackpot symbol. More specifically, if the jackpot symbol is “normal symbol”, “normal state” is set as the gaming status after jackpot, and if the jackpot symbol is “probability variation”, the probability variation is determined as the gaming status after jackpot. State "is set. In general, since the “probability variation state” includes the “short-time state”, the “short-time state” is executed while the “probability variation state” is being executed. In addition, some pachinko machines execute the “short time state” until the special symbol fluctuates a predetermined number of times (for example, 100 times) after the end of the big hit state by the “normal symbol”. In addition, there are pachinko machines in which the probability variation is executed by limiting the number of variations of the special symbol, and such a probability variation state is generally referred to as “number cut probability variation”.

  By the way, at the upper part of each pachinko machine installed in the game store, a liquid crystal display unit for displaying the game history (the number of rotations, the number of jackpots, etc.) of each pachinko machine is provided. It was a guideline for selecting a pachinko machine to perform. In particular, pachinko machines (so-called Hamaridai), which have a large number of rotations after the end of the previous jackpot state (that is, the number of times the special symbol loses fluctuations) give the impression that it is difficult to win a jackpot. There was a tendency. In addition, if the player cannot win a jackpot and the number of revolutions increases (so-called humiliation state), it will not be possible to obtain a prize ball that matches the investment so far. Had spoiled expectations.

For this reason, various pachinko machines have been proposed in which a privilege given to a player is preferentially treated when the number of revolutions counted after the end of the previous jackpot state is reached. For example, based on the degree of repetition of the variable display game required until the big hit state occurs, the total number of prize balls to be paid out in the big win state is changed, and the guide of the total number of payouts is notified to the player. There is a known gaming machine (see, for example, Patent Document 1).
JP 2003-284846 A

  However, in these conventional gaming machines, the gaming state after the jackpot is determined corresponding to only the jackpot symbol, so the probability that the gaming state fluctuates after the jackpot state ends is constant. In other words, regardless of the type of the current gaming state (the gaming state at the time of jackpot), the probability of transition to a gaming state advantageous to the player after the jackpot state ends, or the advantageous gaming state continues is constant. Therefore, the player's expectation for the game state after the jackpot was the same. For this reason, whether or not the time-saving process is executed after the jackpot state ends also has the same expectation for the time-saving process after the jackpot state ends. As described above, the conventional gaming machine has a problem that it is difficult to improve the gameability by using the change of the game state executed after the end of the jackpot state.

  Also, in the past, gaming machines that did not win even though many game balls were won (so-called Hamari stand) tended to be kept away from the players, so inevitably their operation There was a problem that the rate would decrease. On the other hand, if a privilege is given to a player on the hamari table as in the gaming machine according to the invention described in Patent Document 1, the player can be relieved when the player enters the hamari state, and the player On the other hand, it is possible to give a sense of expectation to the Hamari stand, and the operation rate of the pachinko machine can be improved.

  However, in the gaming machine according to the invention described in Patent Document 1, the privilege is given to the player by judging the humili state based on the number of rotations after the end of the previous jackpot state (that is, the number of lost times) It was necessary to separately provide a counter that counts the number of rotations and identifies the humming state. In addition, as a privilege given to players at Hamaridai, it is possible to execute a predetermined number of time-saving processes after the jackpot state ends so that the player can continue the game without reducing the possession, but for that purpose Furthermore, it is necessary to provide a counter for counting the number of executions of the time-saving process.

  As described above, in the conventional gaming machine, in order to give the privilege of the short-time processing to the player of the Hamari stand, it is necessary to provide a plurality of counters and control their operations simultaneously. Furthermore, in such a gaming machine, it is more difficult to control the gaming machine as a whole when trying to control changes in various gaming states such as the above-mentioned “normal state”, “probability variation state”, and “number-of-times probability variation”. In addition, there is a problem that the configuration of the gaming machine is complicated and the manufacturing cost is increased.

  The present invention has been made in order to solve the above-described problems. By changing the probability of executing the time-saving process after the jackpot state is finished according to a predetermined condition, the game value of a plurality of gaming states is different. Providing gaming machines that can improve the gameability and give the player a sense of anticipation of the Hamari stand by giving a privilege of short-time processing to the so-called Hamari stand player with a simple configuration With the goal.

In order to solve the above-described problem, the gaming machine according to the first aspect of the present invention acquires a random number when a game ball wins a winning winning opening having an opening and closing member and a winning of the gaming ball to the starting winning opening. Jackpot random number acquisition means for performing, jackpot determination means for determining whether or not to enter a jackpot state in which a player can acquire a large number of game balls based on the random number acquired by the jackpot random number acquisition means, and the jackpot determination Jackpot determination based on special symbol random number acquisition means for acquiring a special symbol random number for determining a special symbol which is a symbol for notifying the determination result of the means, and the special symbol random number acquired by the special symbol random number acquisition unit A special symbol display means for displaying a special symbol for informing the result, a jackpot state execution means for executing the jackpot state, a detection means for detecting passage of a predetermined position of the game ball, A normal hit random number acquiring means for acquiring random numbers triggered by the passing of the game ball by the detecting means; and a normal hit for opening and closing the opening / closing member of the start winning opening based on the random numbers acquired by the normal hit random number acquiring means A normal winning determination means for determining whether to make a state, a normal symbol display means for displaying a normal symbol for notifying the determination result based on the determination result of the normal winning determination means, and the normal winning determination means One of a plurality of gaming states stored in the gaming state storage means at a predetermined timing, a normal hit state executing means for executing the state, a gaming state storage means for storing a plurality of gaming states in advance a gaming state selecting means for selecting, said a game state gaming machine and a gaming state control means for executing a game state selected by the selection means, said plurality of The skill state includes a normal time determined by the jackpot determination means to be a big hit state with a predetermined jackpot probability, and a time reduction process in which the variation time of the normal symbol displayed on the normal symbol display means is shortened. A plurality of short-time gaming states executed up to the upper limit, and a non-short-time probability variation state in which the probability variation processing in which the jackpot probability is higher than the normal state without being executed, In the gaming state control means, when the gaming state selection means selects the time-stamped probability changing state, which is the time-shortening gaming state in which the time-shortening processing and the probability variation processing are executed, the time-shortening is performed after the jackpot state is over. When the probability variation state is executed, and when the number of times the special symbol has changed from the start of the time variation accuracy variation state reaches the time variation count, the time variation accuracy variation state is entered. Instead, when the non-short-time accuracy variation state is executed, and when the number of fluctuations of the special symbol reaches a predetermined certain number of times that is equal to or greater than the time-short time count from the start of the short-time accuracy variation state, the non-time short-accuracy variation state Instead of executing the normal state, the gaming state selection means, when the winning state is the normal state among all the gaming states, the shortest number of times among the plurality of gaming states When the gaming state after the jackpot state ends is selected with the first probability that the ratio of selecting the highest shortest state that is a large number of the shortest gaming states is the highest, and when the winning state is the short-term probability variation state, When the gaming state after the jackpot state ends is selected with a second probability that the ratio of selecting the shortest time state is less than one probability, and when the winning state is the non-time-short probability variation state, the second probability Before A third probability ratio is small to choose the best time reduction state, and selects a game state after the jackpot state ends.

According to a second aspect of the gaming machine of the present invention, in addition to the configuration of the first aspect of the invention, the maximum time reduction state is a predetermined number of times that the time reduction number is the same as the probability variation number. When the maximum time-short state is selected by the gaming state selection means, the probability variation process and the time-shortening process are continuously executed until the number of fluctuations of the special symbol reaches the predetermined number of times, and When the number of fluctuations of the special symbol reaches the predetermined number, the normal state is executed instead of the shortest time state.

According to a third aspect of the gaming machine of the present invention, in addition to the configuration of the first or second aspect of the invention, the plurality of time-saving gaming states include a plurality of time-change probability changing states each having a different number of time-saving times. The gaming state selection means selects one of the plurality of time-change probability changing states as the gaming state after the jackpot state ends when it is determined by the jackpot determination means that the jackpot state is set. And

According to a fourth aspect of the gaming machine of the present invention, in addition to the configuration of the first or second aspect of the invention, the gaming state control means is a jackpot state with the predetermined jackpot probability by the gaming state selection means. When the normal state with time reduction that is determined to be the short-time gaming state is selected, the normal state with time reduction is executed after the jackpot state ends, and the special symbol is calculated from the start of the normal state with time reduction When the number of fluctuations reaches the time-shortened number, the normal state is executed instead of the time-reduced normal state, and the gaming state selecting means, when the winning state is the time-reduced normal state, The game state after the end of the jackpot state is selected with a fourth probability that the ratio of selecting the shortest time state is smaller than the probability and the ratio of selecting the shortest time state is larger than the second probability. And wherein the Rukoto.

In addition to the configuration of the invention according to any one of claims 1 to 4, the gaming state selection means is initialized when the gaming machine is initialized. The normal state is selected as the gaming state immediately after being played.

The gaming machine of the invention according to claim 1 controls the jackpot based on the random number acquired in response to the winning of the game ball in the starting winning opening, while the random number acquired in response to detection of passage of a predetermined location of the gaming ball. Based on the normal hit control, one of a plurality of gaming states is selected and executed after the big hit state is finished, and when the winning state is the normal state, the probability of selecting the shortest time state is the highest. high. When the winning state is the time-variable probability changing state, the probability of selecting the shortest time state is lower than when the winning state is the normal state. When the winning state is a non-short-time probability variation state, the probability of selecting the highest time-short state is lower than when the winning state is a time variation probability variation state. Therefore, by changing the probability of executing the time-saving process after the jackpot state is finished according to a predetermined condition, it is possible to improve the gameability by providing a difference in the game values of the plurality of game states.

In addition, in the gaming machine of the invention according to claim 2, in addition to the effect of the invention of claim 1, in the shortest time state, the probability variation processing and the time reduction processing have the same number of continuations. When the number of fluctuations of the special symbol reaches the specified number of times in the shortest state, the normal state has a higher probability of selecting the shortest state than the non-short-time state. Executed. Therefore, it is possible to further increase the gaming value in the shortest time state and improve the gaming property.

In addition to the effect of the invention according to claim 1, the gaming machine of the invention according to claim 3 selects one of a plurality of time-change probability changing states as the gaming state after the end of the jackpot state. Therefore, after the big hit state is finished, it is possible to improve the gameability by always giving the privilege of the time reduction process and the probability variation process.

In addition to the effects of the invention according to claim 1, the gaming machine of the invention according to claim 4 has a shorter time when the winning state is a normal state with a shorter time than when the winning state is a normal state. However, the probability of selecting the shortest time state is low, and the probability of selecting the shortest time state is higher than that in the case where the winning state is a time-variable probability variation state. Therefore, since the probability of selecting the shortest time state differs according to the winning state, the gameability can be improved.

In addition to the effect of the invention according to any one of claims 1 to 4, the gaming machine of the invention according to claim 5 is initialized because the normal state is executed when the gaming machine is initialized. Immediately after the game value is increased, the gameability can be improved.

  Next, the storage area of the ROM 53 will be described with reference to FIG. FIG. 5 is a conceptual diagram showing the storage area of the ROM 53. As shown in FIG. 5, the ROM 53 has an initial setting storage area 531 for storing initial values and the like stored in each storage area when the pachinko machine 1 is reset, and the CPU 51 for controlling the pachinko machine 1. A control program storage area 532 for storing various control programs, a control command table storage area 533 for storing a table of control commands output from the main board 41 to the sub-integrated board 58, a special symbol displayed on the special symbol display unit L1, and its A special symbol pattern storage area 534 that stores a variable display pattern, and a gaming state table storage that stores a gaming state table 100 (FIG. 6) for determining a gaming state to be executed after the jackpot state ends (hereinafter referred to as a gaming state after a jackpot). An area 535 and the like are provided. Further, the ROM 53 is provided with various storage areas not shown.

  Here, the gaming state table 100 stored in the gaming state table storage area 535 will be described with reference to FIG. FIG. 6 is a data configuration diagram of the gaming state table 100. As shown in FIG. 6, the gaming state table 100 corresponds to the special symbol random number for determining the special symbol to be displayed on the special symbol display unit L1 and the gaming state at the time of determining the big hit state, and the jackpot state ends. It is a table in which the game state of the transfer destination to be executed later is defined. As will be described later, the special symbol random number is acquired from the special symbol selection counter LC3, the gaming state at the time of determining the big hit state is acquired from the flag information storage area 528, and the gaming state table 100 is based on these pieces of information based on the information. A state is identified.

  In the gaming state table 100 according to the present embodiment, as the gaming state at the time of jackpot state determination, a gaming state (hereinafter referred to as a normal state) with a low probability of jackpot (4/949) and a high probability of jackpot probability (hereinafter referred to as a normal state). 3/698) gaming state (hereinafter referred to as a probability variation state) and a probability variation state (hereinafter referred to as a shortened probability variation state) in which a time-saving process is executed. In addition, the game state after jackpot (that is, the game state of the transition destination) is a probability variation state in which time-saving processing is continuously executed during the probability variation (hereinafter referred to as a maximum time-variable probability variation state), and a time reduction of 100 times. A probability variation state in which processing is executed (hereinafter, referred to as a 100-time short-time probability variation state) and a probability variation state in which 30 time-shortening processing is performed (hereinafter, referred to as a 30-time short-time probability variation state) are defined. ing. In FIG. 6, the MAX short-time accuracy change state is shown as “state A”, the 100-time short-time accuracy change state is shown as “state B”, and the 30-time short-time accuracy change state is shown as “state C”.

  In the pachinko machine 1 according to the present embodiment, “number-of-times probability fluctuation” is executed in which the probability fluctuation state continues until the special symbol fluctuates 300 times as described later. That is, the maximum number of fluctuations of the special symbol in the probability variation state is 300 times, and when the special symbol variation is executed 300 times, the state is shifted to the normal state. In other words, the MAX timed probability variation state is a probability variation state in which 300 time shortening processes are executed.

  Then, according to the gaming state table 100 of FIG. 6, according to the gaming state at the time of the jackpot state determination, the probability associated with the time saving process of MAX (that is, 300 times), 100 times, or 30 times after the jackpot state ends. Transition to a fluctuating state. If the time-saving process of 300 times, 100 times, or 30 times is being executed at the time of jackpot state determination, the gaming state corresponds to the “time-shortening probability change state”. Also, in the time variation with 100 time reduction, after execution of the time reduction processing 100 times, it shifts to the “probability fluctuation state” without time reduction processing, and to the “normal state” when the number of fluctuations of the special symbol reaches 300 times. Is done. Similarly, in the 30-times short-time probability change state, after the execution of 30 time-shortening processes, the state is shifted to the “probability fluctuation state” without the time-shortening process, and when the number of changes in the special symbol becomes 300 times, the “normal state”. To be migrated. In the 300-times time-stabilized certainty change state, when the number of fluctuations of the special symbol (that is, the number of executions of the time-shortening process) reaches 300 times, the state is shifted to the “normal state”.

  Next, the storage area of the RAM 52 will be described with reference to FIG. FIG. 7 is a conceptual diagram showing a storage area of the RAM 52. As shown in FIG. 7, the RAM 52 has a counter storage area 521 for storing various counters, a winning ball flag storage area 522 for storing a flag indicating whether or not a game ball has been won at each gate or each winning opening, Normal hit relation information storage area 523 for storing a random number acquired when winning a game ball to the normal symbol start gate 12, normal symbol operation hold ball number storage area 524 for storing the normal symbol start operation hold ball number, special symbol start Sub-integrated from the main board 41, a jackpot relation information storage area 525 for storing random numbers acquired when winning a game ball to the electric accessory 15, a special symbol operation reservation ball number storage area 526 for storing a special symbol operation reservation ball number Special information indicating whether or not the command related information storage area 527 for storing the control commands output to the substrate 58 and the special symbol display portion L1 are changing. A pattern change flag, a special winning combination act flag indicating whether or not a special winning combination (a general term of electric combination that operates when in a special gaming state) is operating, and a big prize opening 16 A big prize opening flag indicating whether or not it is open, a continuous operation flag indicating whether or not to continue to open the special prize opening 16, a probability variation flag indicating whether or not to enter a high probability state, and time reduction processing are performed. Flag information storage area 528 for storing a time setting flag indicating whether or not, a jackpot after game state storage area 529 for storing a jackpot after game state flag indicating a game state to be executed after the jackpot state is ended by a bit pattern, time reduction processing Time-saving process execution count storage area 530a which is a counter for storing the remaining number of executions, and probability variation execution count storage area 5 which is a counter for storing the remaining execution count of probability fluctuations 0b, and the like are provided. Note that a backup battery (not shown) is connected to the RAM 52 so that stored contents are retained even when the pachinko machine 1 is powered off. Further, the RAM 52 is provided with various storage areas not shown.

  In the time-saving process execution count storage area 530a, when the game state is shifted to a game state in which the time-saving process is executed after the jackpot state is finished, the remaining number of executions of the time-saving process corresponding to the time-reduced game state of the transition destination is described later. It is set after the special electric combination is finished in the special electric combination processing (S7). In this embodiment, the time setting flag is always set to “ON” after the big hit state is ended, and the time saving game state is continued until time setting processing is executed for the set number of times. Details will be described later. For example, if the game state after jackpot is “MAX time-change probability change state”, “300” is set as the remaining number of executions of the time-saving process, and if the game state after jackpot is “100 times time-change probability change state”, the time reduction process “100” is set as the remaining number of executions, and “30” is set as the remaining number of executions of the time-saving process if the game state after the big hit is “30 times timed probability change state”.

  Then, as will be described later, every time the time-saving process is executed in the normal symbol processing (S15), the remaining number of executions of the time-saving process set in the time-saving process execution number storage area 530a is subtracted by “1”. When “0” is set, the time reduction setting flag is set to “OFF”, and the time reduction processing ends. In the time-saving process execution count storage area 530a, if the current game state is a game state where the time-saving process is not executed ("normal state" or "probability variation state" in this embodiment), the remaining execution of the time-saving process is performed. “0” is set as the number of times. Note that, when the pachinko machine 1 is turned on or reset, the “normal state” is executed as the default gaming state. In these cases, “0” is set as the remaining number of executions of the time-saving process.

  In addition, the probability variation execution count storage area 530b is set with the remaining number of executions of probability variation to be executed after the big hit state ends. In the present embodiment, after the jackpot state ends, the probability variation flag is always “ON” and the state changes to the probability variation state, and the probability variation state continues until the special symbol changes 300 times. To do. That is, what is executed by the pachinko machine 1 of the present embodiment is “number-of-times cut probability fluctuation”, and “300” is set as the remaining number of executions of probability fluctuation in the probability fluctuation execution number storage area 530b, which will be described later. It is set after the special electric accessory is finished in the process (S7).

  As will be described later, every time the special symbol variation is executed in the special symbol processing (S9), the remaining number of executions of the probability variation set in the probability variation execution number storage area 530b is subtracted by “1”. When “0” becomes “0”, the probability variation flag becomes “OFF” and the probability variation ends. In the probability variation execution number storage area 530b, when the current gaming state is a gaming state in which probability variation is not executed (“normal state” in this embodiment), “0” is set as the remaining number of executions of probability variation. Set. Note that when the pachinko machine 1 is turned on or reset, the “normal state” is executed as the default gaming state, and in these cases, “0” is set as the remaining number of executions of the probability variation.

  Next, the counter storage area 521 will be described with reference to FIG. FIG. 8 is a conceptual diagram showing the storage area of the counter storage area 521. As shown in FIG. 8, the counter storage area 521 includes a normal hit determination counter LC1 storage area 521a, a big hit determination counter LC2 storage area 521b, a special symbol selection counter LC3 storage area 521c, a special symbol variation time counter TC1 storage area 521d, A prize winning opening time counter TC2 storage area 521e, a prize winning opening closing time counter TC3 storage area 521f, and the like are provided, and various counter values are stored. These values are fetched and stored in the normal hit relation information storage area 523 and the big hit relation information storage area 525 of the RAM 52 in the normal symbol processing and special symbol processing described later.

  The values of the normal hit determination counter LC1, the big hit determination counter LC2, and the special symbol selection counter LC3 are updated in the main routine process (FIG. 10) of the pachinko machine 1 that is executed based on the interrupt signal from the interrupt signal generation circuit 57. In the process (S5), a predetermined amount (for example, “1”) is added every time at a constant interval (for example, 2 ms that is the interval at which the interrupt signal is generated or 20 ms that is the interval at which the interrupt signal is generated 10 times). Is done. Each counter is provided with a maximum value (upper limit value) and a minimum value (lower limit value). When the value becomes the same as the maximum value as a result of the update, the next value returns to the minimum value, and is further added. It is configured to cycle through the numerical values in the range up to the maximum value.

  When the pachinko machine 1 is started, the initial value of each counter is set to a minimum value. Then, when the value of each counter is updated and the value reaches the same value as the initial value, each counter acquires a new initial value, and “1” is added to the initial value. This new initial value is repeatedly performed when the CPU 51 does not perform the main routine process (see FIG. 10) (until the main routine process ends and the main routine process is started by the next interrupt signal). A random number generated by a random number initial value update process (a process for generating a random number by a predetermined algorithm) (not shown) is used. The special symbol fluctuation time counter TC1 is used as a timer counter for measuring the elapsed time. The values of the special symbol variation time counter TC1, the special winning opening opening time counter TC2, and the special winning opening closing time counter TC3 are subtracted by a predetermined amount (for example, “1”), for example, every 2 ms in the counter update process.

  Hereinafter, each counter will be described in detail. The value (random number) of the normal hit determination counter LC1 is used for determining the normal hit. The normal hit determination is performed with the passing of the game ball to the normal symbol start gate 12, and when the normal hit is determined, the opening / closing member of the special symbol start electric accessory 15 is opened for a predetermined time. The maximum value of the normal hit determination counter LC1 is “255” and the minimum value is “0”. When “1” is added every interrupt (every 2 ms) and becomes “256” or more, the value returns to “0”. . Therefore, the value of the normal hit determination counter LC1 takes any value from “0” to “255”, and one period is 512 ms.

  The value of the jackpot determination counter LC2 is used to determine the jackpot. The maximum value of the big hit determination counter LC2 is “11862”, and the minimum value is “0”. When “1” is added every interrupt (every 2 ms) and becomes “11862” or more, the value returns to “0”. Therefore, the value of the jackpot determination counter LC2 takes any value from “0” to “11862”, and one cycle is 23724 ms.

  The value of the special symbol selection counter LC3 is used to select a special symbol displayed on the special symbol display unit L1 in order to notify the result of the jackpot determination. The maximum value of this special symbol selection counter LC3 is “39”, and the minimum value is “0”. When “1” is added every interrupt (every 2 ms) and becomes “40” or more, it becomes “0”. Return. Therefore, the value of the special symbol selection counter LC3 takes any value from “0” to “39”, and one period is 80 ms.

  The special symbol variation time counter TC1 is a timer counter used to measure the variation time of special symbols (the time from the start of symbol variation to the stop). The value is stored at the start of the fluctuation, and “1” is subtracted for each interrupt in the counter updating process. For example, when the variation time is 20 seconds, “10000” is set.

  The big prize opening time counter TC2 is a timer counter for measuring the time during which the big prize opening 16 is opened, and the big prize opening closing time counter TC3 is closed until the next big prize opening 16 is opened. It is a timer counter for measuring the running time. A value is stored in the big prize opening time counter TC2 when the big prize opening 16 is opened, and "1" is subtracted by every interrupt in the counter updating process, and when the value becomes "0", it is judged that the opening time has ended. . The value of the winning prize closing time counter TC3 is stored when the winning prize opening 16 is closed, and "1" is decremented by 1 every interruption in the counter updating process. It is determined that the timing to perform has come.

  Next, the jackpot relation information storage area 525 will be described with reference to FIG. FIG. 9 is a conceptual diagram showing a storage area of the jackpot relation information storage area 525. The jackpot relation information storage area 525 includes four storage areas 1 to 4 which can acquire and store the values of the jackpot determination counter LC2 and the special symbol selection counter LC3 of the counter storage area 521 as random numbers, One determination area for shifting and storing each random number stored in the storage area 1 for performing the determination process is provided, and five storage areas are also provided. The determination area and the storage areas 1 to 4 are each provided with a jackpot random number field and a special symbol random number column. In the jackpot random number column, a value obtained from the jackpot determination counter LC2 is set, and in the special symbol random number column. The value acquired from the special symbol selection counter LC3 is set.

  Next, in the pachinko machine 1 of the present embodiment, details of the main routine processing operation performed by the CPU 51 of the main board 41 will be described according to the flowcharts shown in FIGS. FIG. 10 is a flowchart showing the main routine process. FIG. 11 is a flowchart showing details of the special symbol process (S9). FIG. 12 is a flowchart showing details of the special electric accessory processing (S7). Hereinafter, each step of the flowchart is abbreviated as “S”. A program for performing this process is stored in the control program storage area 532 of the ROM 53 shown in FIG.

  First, the main routine process will be described with reference to the flowchart shown in FIG. When the main routine process is started by the interruption, a command output process for outputting a control command to the sub-board is first performed (S1). In this command output processing, a command for causing the sub-integrated board to perform control of display of the symbol display device 8, control of generation of sound effects from the speaker 48, control of blinking of various lamps, etc., a prize ball payout device 49 A control command such as a command for instructing the control of the player, a command for controlling the opening / closing of the special prize opening 16 via the relay board, and the like, a sub-integrated board 58 and a payout control board 45 via the I / O interface 54. Are output to the relay board 47. Specifically, a flag corresponding to a control command to be output to the sub-integrated board 58 and a variable of the control command are stored in the command relation information storage area 527 of the RAM 52 in each process after S3 of the main routine process. Is done. Then, in the command output processing of the next round of the main routine processing, control commands corresponding to these flags are selected from the control command table storage area 533 of the ROM 53 and output to the sub integrated board 58 together with the variables of the control commands. Is done.

  Next, a switch reading process is performed to detect the winning of game balls in various winning openings (S3). This switch reading process detects the winning of the game ball to the normal symbol starting gate 12, the special symbol starting electric accessory 15, the big winning port 16, the normal winning ports 17, 18, 19, 20 and the like. Specifically, a start port switch 72 provided in the special symbol start electric accessory 15, a normal symbol operation switch 73 provided in the normal symbol start gate 12, and a count switch 75 provided in the special winning opening 16. When the game ball detecting means such as a winning port switch 76 for detecting the winning of the game ball from the winning ports such as the normal winning ports 17, 18, 19, 20 detects the winning of the game ball, the winning ball of the RAM 52 A flag corresponding to each switch is set in the flag storage area 522. Note that the switch reading process is executed at an interrupt interval of the main routine process, that is, every 2 ms. Therefore, considering the speed at which the game ball passes through each switch, the next switch reading process in which the winning of the game ball is detected. In this case, a winning is detected. For this reason, for example, these flags are set for the first time 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, each flag in the winning ball flag storage area 522 is reset.

  When the switch reading process is completed, a counter update process (S5) for updating the counter value stored in the counter storage area 521 is performed. In this counter updating process, the values of the normal hit determination counter LC1, the big hit determination counter LC2, and the special symbol selection counter LC3 (see FIG. 8) respectively stored in the counter storage area 521 of the RAM 52 are incremented by the predetermined amount. The If the updated counter values of the normal hit determination counter LC1, the big hit determination counter LC2, and the special symbol selection counter LC3 exceed the maximum value (upper limit value) set in each loop counter, the value of each loop counter It is programmed to return to “0”. Further, the values of the special symbol variation time counter TC1, the special winning opening opening time counter TC2, and the special winning opening closing time counter TC3 are subtracted by the predetermined amount.

  When the counter update process is completed, a special electric accessory process for controlling the big hit state is performed (S7). In this special electric accessory processing, the opening and closing of the big winning opening 16 in the case of a big win is controlled. In this process, when a game ball wins the special symbol starting electric accessory 15 and the result of the jackpot determination for the game ball is a big hit, the special electric player operation flag is set after the notification of the determination result is finished. Implemented when “ON” is selected. No processing is performed while the special electric accessory actuating flag is “OFF”. This special electric accessory processing will be described later with reference to the flowchart of FIG.

  When the special electric accessory processing is completed, the special symbol processing is performed in which the jackpot determination is performed and the result is displayed on the special symbol display unit L1 (S9). In the special symbol processing, when there is a game ball won in the special symbol starting electric accessory 15, the counter value stored in the counter storage area 521 is taken into the jackpot relation information storage area 525, and whether the counter value taken in is big hit The display mode on the special symbol display unit L1 is determined, or the sub-integrated board 58 is instructed to start or stop changing the special symbol display unit L1. This special symbol process will be described later with reference to the flowchart of FIG.

  When the special symbol process is completed, a normal electric accessory process is performed to open the opening / closing member of the special symbol starting electric accessory 15 when the normal winning is achieved (S13). In this normal electric accessory process, when the normal symbol processing of the next S15 is normal, the result is displayed on the normal symbol display unit 24, and then the game ball can easily win the special symbol starting electric accessory 15. Thus, the opening / closing of the pair of opening / closing members provided in the special symbol starting electric combination 15 (operation in the normal hit state) is controlled. As will be described later, during the time-shortening process, the pair of opening and closing members are controlled to be opened long (for example, normally, 5 seconds is opened for 30 seconds). However, in the first round of the main routine process, the normal hit determination has not yet been performed, so nothing is performed in the normal electric accessory process.

  When the normal electric accessory processing is completed, normal symbol processing for determining normal hit when the game ball passes through the normal symbol start gate 12 is performed (S15). In the normal symbol processing, if the flag corresponding to the normal symbol operation switch 73 in the winning ball flag storage area 522 is set in the switch reading processing of S3 as the game ball passes to the normal symbol start gate 12, the normal hit determination counter The value of LC1 is sequentially stored in the storage areas 1 to 4 of the normal hit relation information storage area 523 of the RAM 52 as a normal symbol random number. Then, based on the normal symbol random number shifted to the determination area, it is determined whether or not the normal symbol is won, the winning symbol or the off symbol to be displayed on the normal symbol display unit 24 is determined, and the normal symbol is displayed on the sub-integrated board 58. An instruction to start or stop the change of the unit 24 is given.

  Since the normal symbol random numbers stored in the normal hit relation information storage area 523 of the RAM 52 are from “0” to “255”, the normal symbol stored in the normal hit relation information storage area 523 of the RAM 52 is used in this normal symbol processing. When the random number is from “0” to “63”, the random symbol is lost, and the normal symbol display unit 24 stops and displays “−” as the shifted symbol. In addition, when the normal symbol random number stored in the normal hit relation information storage area 523 of the RAM 52 is “64” to “255”, the winning symbol is “7”. It has become. If it is determined that the normal hit is made, if “1” is stored in the time setting flag and “ON” is set to “ON”, the time variation command of the normal symbol is transmitted to the sub integrated board 58, and the time setting flag is set. If “0” is stored in “OFF” and “OFF” is set, a normal variation command of a normal symbol is transmitted.

  Here, the time-saving process for normal symbols will be described. As will be described later, when the time setting flag is set to “ON” in the special electric accessory processing (FIG. 12) of S7, the fluctuation time of the normal symbol on the normal symbol display unit 24 is shortened, and the special symbol starting electric role is set. The opening time of the pair of opening / closing members provided on the object 15 becomes longer, and it becomes easier to win a special symbol starting electric accessory 15 for a game ball. Further, the variation time of the normal symbol displayed on the normal symbol display unit 24 is normally 30 seconds, for example, but is set to 5 seconds when the time reduction state is set. Therefore, during the setting of the short time state, the hit determination result is displayed on the normal symbol display unit 24 in a shorter time than in the normal state, and the number of fluctuation displays per unit time is increased. And the frequency that the opening / closing member of the special symbol starting electric accessory 15 is opened increases, and the winning for the special symbol starting electric accessory 15 increases, so that the ball holding is improved.

  In addition, the time reduction process of a normal symbol is not limited to the aspect accompanied by shortening of a change time as mentioned above, For example, you may make it a normal hit probability improve during a time reduction process. Specifically, when the time setting flag is set to “ON” in the special electric accessory processing of S7 (FIG. 12), the normal hit probability changes from 10/256 to 246/256, and the above-mentioned In this way, the opening time of the pair of opening / closing members provided in the special symbol starting electric accessory 15 may be lengthened. In this case, during the setting of the short time state, the probability of normal hitting is higher than in the normal state, so that the opening / closing member of the special symbol starter electric accessory 15 is opened more frequently, and the special symbol starter electric accessory 15 As the number of wins increases, the ball holding will improve.

  Thus, when the winning symbol is displayed on the normal symbol display unit 24, as described above, the opening / closing member of the special symbol starting electric component 15 is opened / closed in the normal electric component processing (S13). It should be noted that it takes a predetermined time until the special symbol start electric accessory 15 applied to the game ball passes after the game ball passes through the normal symbol start gate 12, but during that time other game balls pass through the normal symbol start gate 12. Even in the case, up to four normal symbol random numbers are acquired, and normal symbol startup is suspended. However, in the first process of the main routine process, since there is no game ball that has passed through the normal symbol start gate 12, nothing is performed in the normal symbol process.

  The normal symbol time-saving process is performed when the remaining number of executions of the time-saving process is set in the time-saving process execution number storage area 530a in the special electric accessory process (S12) in S7. The process is executed repeatedly. In addition, the remaining execution count of the time-saving process set in the time-saving process execution count storage area 530a is decremented by “1” for each execution of the time-saving process. When the remaining number of executions of the time reduction process becomes “0”, “0” is stored in the time reduction setting flag and becomes “OFF”, and thereafter normal normal symbol variation is executed.

  Returning to FIG. 10, when the normal symbol process is completed, a payout process for paying out prize balls is performed (S17), and then an error check is performed (S19). When an error has occurred in the pachinko machine 1, the symbol display device 8 displays an error, the illumination lamp 63 performs a lighting / flashing pattern at the time of error, and the speaker 48 generates an error sound. Therefore, a flag (not shown) for causing the sub-integrated board 58 to output an error command is set in the command output process of S1. Then, an information output process is performed (S21). In this information output process, various types of information such as jackpot information, start-up information, probability variation information, time reduction information, etc., of the pachinko machine 1 are output to an unillustrated game hall management computer via the output port 55.

  When the information output process ends, the main routine process ends. Then, the main routine process is started from the beginning by the next interrupt signal from the interrupt signal generation circuit 57.

  For example, when a player operates a launching handle 7 provided on the lower side of the game board 2 to drive a game ball into the game area 4 and the game ball wins the special symbol starting electric accessory 15, the main routine process is performed. In the switch reading process (S3), a winning of the game ball to the special symbol start electric accessory 15 is detected, and the corresponding flag in the winning ball flag storage area 522 is set to “ON”. Then, in the special symbol processing (S9), the values of the normal hit determination counter LC1, the big hit determination counter LC2, and the special symbol selection counter LC3 are taken into the big hit relation information storage area 525. Based on the captured value, the variable symbol display on the special symbol display portion L1 is started. Then, in the next special electric accessory processing (S7) in which the fluctuation of the special symbol display portion L1 is stopped and the result of the jackpot determination is notified, “1” is stored in the special electric accessory operation flag. For example, a big hit state in which the opening / closing operation of the special winning opening 16 is opened / closed a predetermined number of times (for example, 15 times or 16 times) is started. After the jackpot state is ended, “0” is stored in the special electric combination actuating flag in the special electric combination processing, and thereafter, the gaming state set in the post-hit gaming state flag is executed. Then, as will be described later, the gaming state is controlled based on the time reduction setting flag (and the remaining number of executions of time reduction processing), the probability variation flag (and the remaining number of executions of probability variation), and the like.

  Next, the special symbol process performed in S9 of the main routine process will be described with reference to the flowchart of FIG. When the special symbol process is started, it is determined whether or not a game ball has won a special symbol starting electric combination (S101). In the main routine process switch reading process (FIG. 10, S3), when the start opening switch 72 provided in the special symbol start electric accessory 15 detects the winning of the game ball, the winning ball flag storage area 522 of the RAM 52 The flag corresponding to the start port switch 72 is “ON”. It is determined whether or not the flag corresponding to the start port switch 72 is “ON”. If “OFF” (S101: NO), the process proceeds to S109. When the flag corresponding to the start opening switch 72 in the winning ball flag storage area 522 is “ON”, that is, when a game ball wins the special symbol starting electric accessory 15 (S101: YES), the number of pending action balls is “ 4 ”is determined (S103). As described above, the pachinko machine 1 has a specification in which the number of reserved balls for special symbols is stored up to four corresponding to the storage areas 1 to 4, and no further storage is performed, and it is discarded. Accordingly, when the value of the special symbol operation reserved ball number storage area 526 is “4” (S103: YES), the game ball cannot be held any more, so the process proceeds to S109 without doing anything.

  When the number of reserved balls for operation is not “4”, that is, when it is any of “0” to “3” (S103: NO), “1” is added to the value of the special symbol operation reserved ball number storage area 526 ( S105). And the random number acquisition process (S107) which takes in the counter value of the counter storage area 521 to the jackpot relation information storage area 525 is performed. Specifically, out of the storage areas 1 to 4 of the jackpot relation information storage area 525 (see FIG. 9), the counter storage area 521 has a number corresponding to the value of the special symbol operation reserved ball number storage area 526. The stored values of the jackpot determination counter LC2 and special symbol selection counter LC3 are taken in and stored as jackpot random numbers and special symbol random numbers, respectively.

  When the random number acquisition process ends, it is determined whether or not the special electric accessory process is in operation (S109). Specifically, the determination is made based on whether or not “1” is stored in the special electric accessory operation flag of the RAM 52. If the special electric accessory actuating flag is “ON” (S109: YES), since the big hit state is in effect, no big hit determination or instruction to the special symbol display unit L1 is performed, so the special symbol processing is terminated and the main Return to routine processing.

  When the special electric accessory actuating flag is “OFF” (S109: NO), it is determined whether or not the special symbol display portion L1 is changing (S111). This determination is made based on whether or not the special symbol changing flag is “ON”. This special symbol changing flag is set to “ON” by setting “1” after the special symbol start command is set in this special symbol processing (S129), and “0” after the special symbol stop command is set. Is stored and “OFF” is set (S135).

  If the special symbol changing flag is not “ON” and the special symbol is not changing (S111: NO), the jackpot determination is performed. Each value is shifted to the determination area (S113). Similarly, the storage area is shifted one by one for each value stored in the storage areas 2 to 4. That is, the value in storage area 2 is moved to storage area 1, the value in storage area 3 is moved to storage area 2, the value in storage area 4 is moved to storage area 3, and each value in storage area 4 is cleared. Then, the reserved ball number subtraction process is performed to subtract “1” from the number stored in the special symbol operation reserved ball number storage area 526 (S115). When there is no value to be shifted to the determination area in S113 (that is, when there is no reserved ball to be subtracted in S115), the special symbol process (FIG. 11) is terminated.

  Then, using the value stored in the jackpot random number column of the determination area, it is determined whether or not the jackpot is large (S117). In the jackpot determination process, it is determined whether or not the value stored in the jackpot random number column of the determination area is a specific value determined as a jackpot. Here, if the probability variation flag is “OFF”, it is in a normal state, so the value determined as a jackpot is 50 specific values out of 11863 jackpot random numbers. On the other hand, in the probability variation state in which the probability variation flag is “ON”, the value determined as the jackpot is the specific 51 values among 11863 jackpot random numbers. In other words, in the normal state, a jackpot lottery is performed with a jackpot probability of 4/949, whereas in a probability variation state, a jackpot lottery is performed with a jackpot probability of 3/698. Note that, in the special electric accessory processing (S12) described later, “1” is stored and “ON” is stored in the probability variation flag, or “0” is stored and “OFF” is stored.

  As a result, when it is determined that it is a big hit (S117: YES), based on the special symbol random number stored in the special symbol random number column of the determination area, the 40 types of symbols stored in the special symbol pattern storage area 534 are stored. One of the jackpot special symbols is selected (S119). On the other hand, if the jackpot is not determined (S117: NO), the 40 types of special symbol pattern storage area 534 stored in the special symbol random number column stored in the special symbol random number column of the determination area are used. One is selected from the special symbols of detachment (S121).

  Then, after S119, referring to the gaming state table 100 (FIG. 6) stored in the gaming state table storage area 535, a new jackpot is added to the gaming state storage area 529 after the jackpot based on the gaming state at the time of jackpot state determination. After game state is set (S123). That is, in S123, based on the probability variation flag and the time reduction setting flag in the flag information storage area 528, the game state at the time of jackpot state determination (that is, the current state) is “normal state”, “probability variation state”, “time reduction probability change The state is specified. When the special symbol random number is acquired from the jackpot relation information storage area 525, the gaming state table 100 (see FIG. 6) is referred to based on the gaming state and the special symbol random number at the time of the jackpot state determination. Then, the next big hit game state is identified from the gaming state table 100, and is set in the big hit game state flag.

  For example, if the probability variation flag “OFF” and the time setting flag “OFF” are set in the flag information storage area 528, the gaming state at the time of jackpot state determination is “normal state”. In this case, with reference to the gaming state table 100, the “state A (MAX short-term probability variation state)” is specified regardless of which special symbol random number is acquired. Then, a bit pattern “1” indicating the next big hit game state “state A” is set in the big jackpot after gaming state flag in the big jackpot gaming state storage area 529.

  If the probability variation flag “ON” and the time reduction setting flag “OFF” are set in the flag information storage area 528, the gaming state at the time of jackpot state determination is “probability variation state”. In this case, with reference to the gaming state table 100, for example, when “7” is acquired as a special symbol random number, “state C (30 times shortened probability variation state)” is specified. Then, a bit pattern “3” indicating the next jackpot after gaming state “state C” is set in the jackpot after gaming state flag in the jackpot after gaming state storage area 529.

  Further, if the probability variation flag “ON” and the short time setting flag “ON” are set in the flag information storage area 528, the gaming state at the time of determining the big hit state is the “probability changing state with short time”. In this case, with reference to the gaming state table 100, for example, when “7” is acquired as a special symbol random number, “state B (100-times shortened probability variation state)” is specified. Then, a bit pattern “2” indicating the next jackpot after gaming state “state B” is set in the jackpot after gaming state flag in the after jackpot gaming state storage area 529.

  On the other hand, after the execution of S121, it is determined whether or not the probability is currently changing (S125). Here, if the probability variation flag is “ON”, the probability variation state is established (S125: YES), so the remaining probability variation count is counted in the probability variation execution count storage area 530b (S127). Specifically, in S127, the remaining number of executions of the probability variation set in the probability variation execution number storage area 530b is subtracted by “1”. Here, when the remaining number of executions of the probability variation set in the probability variation execution number storage area 530b is “0”, “0” is stored in the probability variation flag and “OFF” is set, and the gaming state is “ Transition to “normal state”. If the probability variation flag is “OFF”, the normal state is set (S125: NO), and therefore “0” is set in the probability variation execution count storage area 530b, and the process proceeds to the next step. .

  Returning to FIG. 11, after S123 or S127, the special symbol start command for instructing the start of the special symbol notification is stored in the command related information storage area 527 of the RAM 52 together with the code indicating the special symbol determined in S123 or S127. (S128). Then, “1” is stored in the special symbol changing flag and becomes “ON”, indicating that the special symbol is changing (S129).

  By the way, if the special symbol is changing (S111: YES), the jackpot determination result for the already won game ball is changing, and the processing for the next winning ball is not performed until this is finished, so the change It is determined whether or not to end (S131). This determination is made based on whether or not the value of the special symbol change time counter TC1 is “0”. If the special symbol still continues to fluctuate (S131: NO), the special symbol process is terminated and the process returns to the main routine process. If it is the timing when the change ends (S131: YES), a special symbol stop command is stored in the command related information storage area 527 of the RAM 52 (S133). The special symbol stop command is output to the sub integrated board 58 in the command output process (see FIG. 10) of S3 in the next main routine process. Then, “0” is stored in the special symbol changing flag and set to “OFF” (S135). Then, “1” is stored and turned “ON” in the special electric accessory actuating flag (S137), a big hit state is entered, and a big prize opening process is performed to open the first big prize opening 16 ( S139), the special symbol process is terminated and the process returns to the main routine process. In the special prize opening process, a special prize opening command is set, “1” is stored in the special prize opening flag, and “ON” is set. And in order to measure the opening time of the big winning opening 16, the opening time is stored in the big winning opening opening time counter. Then, “0” is stored and cleared in the big prize opening winning ball counter for counting the number of game balls won in the big winning opening 16. Then, “1” is stored in the special winning opening opening number counter for counting the number of opening of the special winning opening 16.

  As described above, a special symbol to be displayed on the special symbol display unit L1 can be determined, or a change start / end instruction command can be transmitted to the sub-integrated board 58.

  Next, with reference to the flowchart of FIG. 12, the special electric accessory process performed in S7 of the main routine process will be described. Here, the control of the jackpot state that is performed when the result of the jackpot determination is a jackpot is performed. Specifically, in the special symbol process, when the special electric accessory activation flag is set to “ON” and the first big prize opening 16 is opened (see S139 in FIG. 11), Opening / closing control is performed. In the big hit state, the opened big winning opening 16 is closed when a predetermined opening time (for example, 30 seconds) elapses or a predetermined number (for example, 10 balls) of winning balls are won. Then, the special winning opening 16 is continuously opened up to a predetermined specified number of times (for example, 15 times). In other words, the jackpot state ends when the specified number of large winning openings 16 is opened. In the present embodiment, when the jackpot state ends, a jackpot state end command is transmitted to the CPU 581 of the sub-integrated board 58.

  When the special electric accessory processing is started, first, it is determined whether or not “1” is stored in the special electric accessory operation flag and is “ON” (S151). If it is not “ON” (S151: NO), it is not necessary to perform the process, so the special electric accessory process is terminated and the process returns to the main routine process. When the special electric accessory actuating flag is “ON” (S151: YES), it is determined whether or not the special winning opening 16 is open (S153). If the big winning opening 16 is open (S153: YES), it is determined whether or not the count switch 75 detects a winning of a game ball to the big winning opening 16 (S155). (S155: YES), “1” is added to the winning prize winning ball counter (S157). If no winning is detected (S155: NO), nothing is done.

  Then, it is determined whether a predetermined opening time has elapsed (S163). This determination is made based on whether or not the value of the big winning opening opening time counter TC2 set when the big winning opening 16 is opened is 0 or less. If the value of the big winning opening opening time counter TC2 is not less than 0 and the opening time has not yet elapsed (S163: NO), it is determined whether or not a prescribed number of game balls have won (S165). ). This determination is made based on whether or not the value of the winning prize winning ball counter is 10 balls or more. If it is not more than 10 balls (S165: NO), the winning prize opening 16 is continuously opened. This process is terminated without doing anything, and the process returns to the main routine process. When the opening time has elapsed (S163: YES), or when a prescribed number of game balls have won (S165: YES), a process for closing the special winning opening 16 is performed. That is, a special winning opening closing command is transmitted to the relay board 47 (S167), "0" is stored in the special winning opening release flag, and is turned "OFF" (S169). Then, the time during which the special winning opening 16 is closed is set in the special winning opening closing time counter TC3 (S171), this process is terminated, and the process returns to the main routine.

  In S153, when the special winning opening 16 is not open (S153: NO), it is determined whether or not the predetermined closing time of the special winning opening 16 has passed (S173). This determination is made based on whether or not the value of the special winning opening closing time counter TC3 set when the special winning opening 16 is closed is 0 or less. If the value of the big prize closing time counter TC3 is not less than 0 and the predetermined closing time has not yet elapsed (S173: NO), the special prize opening 16 is still closed. The process is terminated without returning to the main routine process. When the predetermined closing time has elapsed (S173: YES), processing for opening the big prize opening 16 (S179 to S186) or processing for ending the big win state (S187 to S199) is performed.

  First, it is determined whether or not “1” is stored in the continuous operation flag and is “ON” (S175). If it is “ON” (S175: YES), it is determined whether or not the special winning opening 16 has been opened a specified number of times (S177). When the value of the special winning opening opening number counter is less than 15, since the predetermined number of opening has not been completed (S177: NO), a process for opening the special winning opening 16 is performed. First, a special winning opening release command is transmitted to the relay board 47 (S179), and "1" is stored in the special winning prize flag and becomes "ON" (S181). Then, the time for opening the big prize opening 16 is set in the big prize opening time counter TC2 (S183), "0" is stored in the big prize opening prize ball counter and the number of winning balls is cleared (S185). ). Then, “1” is added to the special winning opening opening number counter (S186), this process is terminated, and the process returns to the main routine process.

  Further, when the continuous operation flag is not “ON” (S175: NO), or when the specified number of large winning openings 16 has been opened (S177: YES), the big hit state is ended. First, a big hit state end command is transmitted to the sub-integrated board 58 (S187), and “0” is stored in the special electric accessory actuating flag and becomes “OFF” (S189). Then, the jackpot after-game state flag set in the jackpot after-game state storage area 529 is read (S191). This after-hit game state flag is set in the after-hit game state storage area 529 in S123 of the above-described special symbol processing (FIG. 11).

  Next, the probability variation flag in the flag information storage area 528 is set based on the gaming state after jackpot read in S191 (S193), and the remaining number of executions of probability variation is set in the probability variation execution count storage area 530b. (S195). As described above, in this embodiment, in the gaming state that shifts after the jackpot state ends, the probability variation is always performed until 300 special symbol variations are executed. For this reason, “1” is set to “ON” in the probability variation flag in S193, and “300” is set as the remaining number of executions of the probability variation in S195.

  Next, based on the jackpot post-hit gaming state read in S191, the time setting flag in the flag information storage area 528 is set (S197), and further, based on the jackpot post-hit gaming state read in S191, The remaining number of executions of the time-saving process is set in the execution number storage area 530a (S199). As described above, in this embodiment, the time reduction process is always executed in the gaming state that is shifted to after the jackpot state ends, and therefore, in S197, the time reduction setting flag is set to “1” and becomes “ON”. On the other hand, the number of executions of the time-saving process set in S199 differs depending on the jackpot after-game state read in S191.

  For example, when “state A” is set in the after-hit gaming state flag, “1” is stored in the probability variation flag and becomes “ON”, and “1” is stored in the time setting flag and “ON” "MAX (300)" is set as the remaining number of executions of the time-saving process in the time-saving process execution number storage area 530a. Similarly, when “state B” or “state C” is set in the after-hit gaming state flag, the probability variation flag and the time-shortening setting flag are both “ON”, but the time-shortening processing execution count storage area 530a Is set to “100” or “30”.

  Then, this process ends, and the process returns to the main routine process. In the subsequent processing, “state A”, “state B” as the jackpot after-game state according to the setting contents of the probability variation flag (and the remaining number of executions of the probability variation) and the time setting flag (and the remaining number of executions of the time reduction processing). "Or" State C "is executed.

  For example, when “State A” is selected as the gaming state after the jackpot, the jackpot determination is performed in the probability variation state (hit probability: 4/949) after the jackpot state ends, and unless the jackpot is won, During the probability change, the time-saving process is continuously executed. When the time reduction process is executed 300 times and the time reduction process execution count storage area 530a becomes “0”, “0” is stored in the probability variation flag and the time reduction setting flag and becomes “OFF”, and thereafter The jackpot determination is performed in the state (probability of jackpot: 3/698).

  In addition, when “State B” is selected as the game state after the jackpot, the jackpot determination is performed in the probability variation state after the jackpot state ends, and 100 time-saving processes are executed unless the jackpot is won. The When the time-saving process is executed 100 times and the time-saving process execution count storage area 530a becomes “0”, “0” is stored in the time-saving setting flag and becomes “OFF”, and thereafter the normal normal symbol variation Is executed. Furthermore, when the number of revolutions after the end of the big hit state (that is, the number of fluctuations of the special symbol) reaches 300, “0” is stored in the probability fluctuation flag and becomes “OFF”. A determination is made.

  In addition, when “State C” is selected as the gaming state after the jackpot, the jackpot determination is performed in the probability variation state after the jackpot state ends, and 30 time-saving processes are executed unless the jackpot is won. The When the time-saving process is executed 30 times and the time-saving process execution count storage area 530a becomes “0”, “0” is stored in the time-saving setting flag and becomes “OFF”, and thereafter the normal normal symbol variation Is executed. Furthermore, when the number of revolutions after the end of the big hit state (that is, the number of fluctuations of the special symbol) reaches 300, “0” is stored in the probability fluctuation flag and becomes “OFF”. A determination is made.

  As described above, when the jackpot 16 is opened and closed in the jackpot state, and when the jackpot state ends, a jackpot state end command is transmitted to the CPU 581 of the sub-integrated board 58 and flag information The jackpot after-game state dynamically set in the storage area 528 is executed.

  Next, with reference to FIG. 13 and FIG. 14, the control of the gaming state in the pachinko machine 1 having the above-described configuration and processing will be described. FIG. 13 is a state correspondence table for explaining changes in the gaming state in the first embodiment. FIG. 14 is a state transition diagram for explaining the change in the gaming state in the first embodiment.

  As described above, in the pachinko machine 1 according to the present embodiment, the game state after the jackpot is determined based on the game state table 100 (see FIG. 6). As shown in FIG. 13, in the gaming state table 100, whether or not the gaming state at the time of determining the jackpot state is any of “normal state”, “probability variation state”, and “short-term probability variation state”, the determination result Is set to shift to a high-probability state by changing the probability after the end of the jackpot state, regardless of the special symbol random number.

  Furthermore, when the gaming state at the time of jackpot state determination is “normal state”, all of the special symbol random numbers corresponding to the jackpot are set to be accompanied by a time-saving process of the maximum number of executions (300 times). Therefore, when a big hit is made in the “normal state”, the probability that the gaming state after the big hit becomes “state A” is 100%.

  Also, when the game state at the time of jackpot state determination is “probability variation state”, 2% of the special symbol random numbers corresponding to the jackpot is accompanied by time-saving processing of the maximum number of executions (300 times), and the other 49% is 100 The remaining 49% is set to be accompanied by 30 time-saving processes. Therefore, when a big hit is made in the “probability variation state”, the probability that the gaming state after the big hit is “state A” is 2%, the probability of “state B” is 49%, The probability of “C” is 49%.

  In addition, when the game state at the time of jackpot state determination is “probability with time reduction”, 50% of the special symbol random numbers corresponding to the jackpot is accompanied by the time-saving process of the maximum number of executions (300 times), and the remaining 50% It is set to be accompanied by 100 time-saving processes. Therefore, when a big hit is made in the “short-time probability change state”, the probability that the gaming state after the big hit will be “state A” is 50%, and the probability that it will be “state B” is 50%.

  As described above, in the pachinko machine 1, a plurality of game states each having a unique game value are controlled to be shifted in various ways triggered by the jackpot. By the way, in the present embodiment, there is substantially no difference in the jackpot probability between the low probability state (jackpot probability: 4/949) and the high probability state (jackpot probability: 3/698). Therefore, it can be said that the more advantageous the short-time processing privilege given after the big hit state is, the more advantageous game state for the player.

  That is, the above-mentioned “normal state” is the most advantageous gaming state for the player because it always shifts to the MAX time-saving gaming state (state A) in which the bonus for time-saving processing is the largest when the state is a big hit. In addition, in the “probability fluctuation state”, when the jackpot is in that state, the probability of shifting to the MAX time-saving gaming state (state A) with the most short-time processing benefits is extremely low, and conversely, the short-time processing privileges are the least 30 times. Since there is a high probability of shifting to the time-reduced gaming state (state C), this is the most disadvantageous gaming state for the player. In addition, since the “time-stamped promising state” shifts to the MAX short-time gaming state (state A) or the 100-times short-time gaming state (state B), which has a lot of time-saving processing benefits when it becomes a big hit in that state, This is a relatively advantageous gaming state.

  As a result of defining the gaming state table 100 as described above, the gaming state controlled by the pachinko machine 1 changes as follows. As shown in FIG. 14, when the pachinko machine 1 is powered on or initialized by reset, the pachinko machine 1 executes a low-probability state (that is, a normal state) without time-saving processing as a gaming state. The This “normal state” is continued until the jackpot is reached, and when the jackpot is reached, the probability of shifting to “state A” is 100%.

  When the state is shifted to “state A”, the probability change to the high probability state and the time reduction process is continuously executed. Then, if a big hit is made during the time-shortening processing in this “state A” (that is, the time-variable accuracy variation state), the probability that “state A” will continue is 50%, and the probability of transition to “state B” is 50%. It is. On the other hand, in the “state A”, when the special symbol variation (in other words, the time saving process) is executed 300 times, the state shifts to the “normal state”.

  When transitioning to “state B”, the probability changes to a high-probability state and 100 time-saving processes are executed. If a big hit is made during the time-saving process in this “state B” (that is, the time-varying probability variation state), the probability of transitioning to “state A” is 50%, and the probability that “state B” will continue is 50%. On the other hand, in the “state B”, when the time shortening process is executed 100 times, the state shifts to a high probability state (that is, a probability variation state) without the time shortening process.

  When shifting to the “probability fluctuation state”, a high probability state without time-saving processing is executed. Then, when a big hit is made in this “probability variation state”, the probability of transition to “state A” is 2%, the probability of transition to “state B” is 49%, and the probability of transition to “state C” is 49%. On the other hand, in the “probability fluctuation state”, when the number of rotations (the number of special symbol fluctuations) counted after the end of the previous jackpot is 300, the state shifts to the “normal state”.

  When transitioning to “state C”, the probability changes to a high probability state and 30 time-saving processes are executed. If a big hit is made during time-shortening processing in this “state C” (that is, the time fluctuation accuracy variation state), the probability of transitioning to “state A” is 50%, and the probability of transitioning to “state B” is 50%. . On the other hand, in the “state C”, when the time reduction process is executed 30 times, the state shifts to the “probability variation state”.

  That is, in the pachinko machine 1 according to the present embodiment, as a result of controlling the gaming state as described above, after the time-shortening process is executed 300 times or the special symbol variation is executed 300 times, the high probability state is entered. The probability variation of the process ends, and the state shifts to the “normal state”. Therefore, in this pachinko machine 1, when the number of executions of short-time processing or special symbol variation is large (so-called hamari state), the benefits of the short-time processing after the big hit are the most, and the “normal state” that is most advantageous for the player Transition control is performed. Therefore, it is possible to provide relief when the player enters the stalemate state, and to give the player a sense of expectation on the scented stand.

  Further, when the pachinko machine 1 is initialized by turning on or resetting the power, the default gaming state starts with the “normal state” that has the most benefits of time-saving processing after jackpot and is most advantageous to the player. Therefore, immediately after the pachinko machine 1 is turned on (reset), the player can enjoy the game from the “normal state” which is the most advantageous gaming state, and can improve the entertainment in various ways. .

  Further, in the pachinko machine 1, the state shifts from the “normal state” to the “state A” after the big hit state ends. When the big hit is made in the “state A”, the state shifts to “state A” or “state B” after the big hit state ends. . In both “state A” and “state B”, the benefit of time-saving processing is advantageous, and there is a high possibility that the state will again shift to “state A” or “state B” after the jackpot state ends. That is, if the big win is won when the pachinko machine 1 is in a stalemate state, a gaming state advantageous to the player is likely to occur continuously, so that the expectation and game performance of the pachinko machine 1 can be further improved.

  As described above, in the pachinko machine 1 according to the present embodiment, the setting of the time reduction condition for each gaming state using the gaming state table 100 and the number cutting using the probability variation execution number storage area 530b (remaining number of executions of probability variation) are performed. By controlling the probability variation, the relief of the hamari state (preferential treatment of the hamari stand) and preferential treatment at the initial state (giving a privilege at the time of resetting) are performed. More specifically, a certain degree of regularity is given to the transition of the gaming state by the probability variation probability change of the number of turns, and further, a time gap condition selected according to the gaming state at the time of jackpot state determination is provided with a gap. And, for one of the gaming states that change with a certain degree of regularity (here, “normal state”), by giving preferential treatment to the short-time processing privilege given to the gaming state after the jackpot, It has the highest gaming value both in the initial state. In other words, when the big hit is made in the humming state or the initial state (that is, the “normal state”), the time-change probability changing state “state A” that is most advantageous for the player is executed. Therefore, in the pachinko machine 1 according to the present invention, there is no need to separately provide a counter for relieving the humorous state as in the prior art, and a privilege advantageous to the so-called hamari player only by controlling the gaming state as described above. Can be granted. Furthermore, not only granting a privilege to the Hamari table but also giving a privilege advantageous to a player of a so-called reset table can be realized at the same time.

  As described above, according to the pachinko machine 1 according to the first embodiment, while the jackpot control is performed based on the jackpot random number acquired in response to the winning of the game ball to the special symbol start electric accessory 15, The normal hit control is performed based on the normal hit random number acquired when the passage of the symbol start gate 12 is detected, and one of a plurality of gaming states is selected and executed after the big hit state is finished. The probabilities of selecting game states “state A” to “state C” for executing the time-saving process among the states are different based on the game state table 100.

  Then, regardless of the gaming state at the time of jackpot state determination, after execution of the jackpot state, it always shifts to a gaming state with a probability variation (that is, “State A”, “State B”, “State C”). To do. Furthermore, if the number of changes in the special symbol becomes 300 times or more during execution of the “probability variation state”, the state shifts to the “normal state” while the game state at the time of determining the big hit state is “normal state” After the completion of the state, the game state “state A” having the largest number of executions of the time-saving process is entered.

  Therefore, by combining the gaming state table 100 and the number cut probability fluctuation to change the probability of executing the time-saving process after the jackpot state ends, it is possible to improve the gameability by providing a difference in the gaming values of a plurality of gaming states. it can. Furthermore, since the privilege of the short-time processing for the pachinko machine 1 that is in the humili state only by controlling the gaming state is preferentially given, the privilege of the short-time processing is given to the player of the so-called Hamari table with a simple configuration, and the player Can give a sense of expectation to the Hamari stand. In addition, when the pachinko machine 1 is reset to the initial state, it shifts to the “normal state”, so that the player can enjoy the game from the “normal state” in which the privilege of giving a short time is preferentially controlled. You can improve your interest in various ways.

  Next, a second embodiment of the pachinko machine 1 that embodies the gaming machine according to the present invention will be described with reference to the drawings. The second embodiment is basically the same as the first embodiment, but the transition control of the game state after the big hit is different. Only the differences from the first embodiment will be described below.

  In the pachinko machine 1 according to the first embodiment, the transition of the three patterns of the game state consisting of “normal state”, “probability variation state”, and “short-time probability variation state” is controlled. In the pachinko machine 1 according to the embodiment, transition control is performed for four patterns of game states including a normal state in which a time reduction process is executed (hereinafter referred to as a normal state with a time reduction). In the present embodiment, as in the first embodiment, the jackpot probability in the normal state is low (4/949), and the jackpot probability in the probability variation state is high (3/698). In the probability variation state, it is assumed that “number-of-times probability variation” is executed in which probability variation is executed until the number of variations of the special symbol reaches 300.

  Therefore, although not shown, in the gaming state table 100 according to the present embodiment, as the gaming state at the time of jackpot state determination, the above-mentioned “normal state”, “normal state with time reduction”, “probability variation state”, “time reduction” "Probable change state" is set. In addition, the game state after the big hit is a normal state where the time-saving process is not performed (hereinafter referred to as “state A”) and a normal state where the time-saving process is executed 100 times (hereinafter referred to as “state B”). A probability variation state in which time-shortening processing is not performed (hereinafter referred to as “state C”), a probability variation state in which 100 time-shortening processing is performed (hereinafter referred to as “state D”), and during probability variation A probability variation state (hereinafter referred to as “state E”) in which time-saving processing is continuously executed is defined.

  In the present embodiment, “state A” corresponds to “normal state” without time reduction processing, and “state C” corresponds to “probability fluctuation state” without time reduction processing. In the “state B”, if the time reduction process is being executed at the time of determining the big hit state, it corresponds to the “normal state with time reduction”, and after the execution of the time reduction process 100 times, the process shifts to the “normal state”. Also, in “State D”, if the time reduction process is being executed at the time of determining the big hit state, it corresponds to the “time-variable probability change state”, and after executing 100 time reduction processes, the state is shifted to the “probability change state”, and further special When the number of symbol changes reaches 300, the state is shifted to the “normal state”. Note that “state E” corresponds to the “probability change state with time reduction” because the time reduction process is continuously executed, but when the number of times the special symbol fluctuates (that is, the number of executions of the time reduction process) reaches 300, “normal” Transition to "state".

  By the way, in the first embodiment, when the special symbol processing (see FIG. 11) is determined to be a big hit, the big hits are all “probability fluctuation big hits” accompanied by probability fluctuations. On the other hand, in the present embodiment, there is the above-mentioned “probability variation jackpot” and “normal jackpot” that does not involve probability variation after the end of the jackpot state. Therefore, in the following, when it is determined that “normal jackpot”, the game state shifts to either “state A” or “state B” without probability fluctuation after the jackpot state ends, while “probability fluctuation jackpot” ”, The game state is shifted to any one of the“ state C ”,“ state D ”, and“ state E ”with a probability change after the end of the jackpot state.

  Here, with reference to FIG.15 and FIG.16, control of the gaming state in the pachinko machine 1 of this embodiment is demonstrated. FIG. 15 is a state correspondence table for explaining changes in the gaming state in the second embodiment. FIG. 16 is a state transition diagram for explaining a change in the gaming state in the second embodiment.

  In the pachinko machine 1 according to the present embodiment, similarly to the first embodiment, if the jackpot determination result is a jackpot, the gaming state after the jackpot is determined based on the gaming state table 100. . Then, as shown in FIG. 15, in the gaming state table 100, in response to the special symbol random number and the jackpot gaming state, the state shifts to any one of “state A” to “state E” after the jackpot state ends. Is set to

  Specifically, regardless of whether the gaming state at the time of jackpot state determination is “normal state”, “normal state with time reduction”, “probability variation state”, or “probability variation state with time reduction”, the gaming state after the jackpot is “ The probability of becoming “State A” is 5%, and the probability of becoming “State B” is 5%. In other words, in this embodiment, regardless of the gaming state at the time of determining the jackpot state, the probability of being a “ordinary jackpot” among the jackpots is 10%. "Is 90%.

  Specifically, when the game state at the time of jackpot state determination is “normal state”, the probability that the game state after the jackpot will be “state E” is 90%. In addition, when the gaming state at the time of jackpot state determination is “normal state with time reduction”, the probability that the gaming state after the jackpot is “state D” is 80%, and the probability of “state E” is 10%. . Further, when the gaming state at the time of jackpot state determination is “probability variation state”, the probability that the gaming state after that jackpot will be “state C” is 44%, and the probability of “state D” is 44%, The probability of “state E” is 2%. Further, when the game state at the time of jackpot state determination is “probability change state with time reduction”, the probability of becoming “state D” is 45%, and the probability of becoming “state E” is 45%.

  As described above, in the pachinko machine 1, a plurality of game states each having a unique game value are controlled to be shifted in various ways triggered by the jackpot. By the way, in the present embodiment, there is substantially no difference in the jackpot probability between the low probability state (jackpot probability: 4/949) and the high probability state (jackpot probability: 3/698). Therefore, it can be said that the more advantageous the short-time processing privilege given after the big hit state is, the more advantageous game state for the player.

  That is, the above-mentioned “normal state” is the most advantageous gaming state for the player because the probability of shifting to “state E” having the greatest number of time-saving benefits when the state is a big hit is extremely high. In addition, the “normal state with time reduction” is a game state that is advantageous to the player because there is a high probability of shifting to “state E” with the most benefits of time reduction processing when a big hit is made in that state. In addition, the “probability variation state” has a very low probability of shifting to “state E”, which has the greatest number of short-time processing benefits, and conversely, “state C” has the lowest expectation for the short-time processing privileges. Therefore, the game state is the most disadvantageous for the player. In addition, the “probability change state with time reduction” is a game state that is relatively advantageous to the player because there is a high probability of shifting to “state D” or “state E” with many benefits of time reduction processing when a big hit is made in that state. .

  As a result of defining the gaming state table 100 as described above, the gaming state controlled by the pachinko machine 1 changes as follows. As shown in FIG. 16, when the pachinko machine 1 is powered on or initialized by reset, the pachinko machine 1 has a low-probability state (that is, a “normal state” state without time-saving processing) as a gaming state. A ") is executed. This “state A” is continued until the big hit, and when the big hit is reached, the probability that “state A” will continue is 5%, the probability of shifting to “state B” is 5%, and the state shifts to “state E” The probability of doing is 90%.

  When transitioning to “state B”, transition to the low-probability state and 100 time reduction processes are executed. Then, if a big hit is made during the time-shortening processing in this “state B” (that is, the normal state with time reduction), the probability of shifting to “state A” is 5%, and the probability that “state B” will continue is 5%. Yes, the probability of transitioning to “state D” is 10%, and the probability of transitioning to “state E” is 80%. On the other hand, in the “state B”, when the time reduction process is executed 100 times, the state shifts to the “state A”.

  When the state transitions to “state E”, the probability change to the high probability state and the time reduction process is continuously executed. Then, if a big hit is made during the time-saving process in this “state E” (that is, the time-varying probability variation state), the probability of transitioning to “state A” is 5%, and the probability of transitioning to “state B” is 5%. Yes, the probability of transitioning to “state D” is 45%, and the probability of “state E” continuing is 45%. On the other hand, in the “state E”, when the special symbol change (in other words, the time saving process) is executed 300 times, the state shifts to the “state A”.

  When the state transitions to “state D”, the probability changes to a high probability state and 100 time-saving processes are executed. Then, if a big hit is made during the time-saving process in this “state D” (that is, the time-varying probability variation state), the probability of shifting to “state A” is 5%, and the probability of shifting to “state B” is 5%. Yes, the probability that “state D” will continue is 45%, and the probability of transition to “state E” is 45%. On the other hand, in the “state D”, when the time reduction process is executed 100 times, the state shifts to the “state C”.

  When the state transitions to “state C”, a high-probability state (that is, a probability variation state) that does not involve time-saving processing is executed. Then, when a big hit is made in “state C”, the probability of transition to “state A” is 5%, the probability of transition to “state B” is 5%, and the probability of “state C” continuing is 444. The probability of transitioning to “state D” is 44%, and the probability of transitioning to “state E” is 2%. On the other hand, in the “state C”, when the number of rotations (the number of special symbol fluctuations) counted after the end of the previous jackpot is 300 times, the state shifts to the “state A”.

  That is, in the pachinko machine 1 according to the present embodiment, as a result of controlling the gaming state as described above, after the time-shortening process is executed 300 times or the special symbol variation is executed 300 times, the high probability state is entered. After the probability fluctuations of FIG. 4 are finished, the state shifts to the “normal state (state A)”. Therefore, in this pachinko machine 1, when the number of executions of short-time processing or special symbol variation is large (so-called hamari state), there is a probability that the transition control is performed to “state E” having the most benefits of short-time processing after big hits. Extremely expensive. Therefore, it is possible to provide relief when the player enters the stalemate state, and to give the player a sense of expectation on the scented stand.

  Also, when the pachinko machine 1 is initialized by powering on or resetting it, the default gaming state has the most benefits of time-saving processing after jackpot and starts from the “normal state (state A)” that is most advantageous to the player. Is done. Therefore, immediately after the pachinko machine 1 is turned on (reset), the player can enjoy the game from “state A”, which is the most advantageous gaming state, and can improve the entertainment in various ways. .

  Further, in the pachinko machine 1, after the big hit state is ended from “state A”, the state shifts to “state A”, “state B”, or “state E”. And if it is a big hit in this "state A" or "state B", the probability that it will transfer to "state E" with most privilege of a time-short process after the end of the big hit state is high. In addition, when a big hit is made in “state E”, there is a high probability that after the big hit state ends, “state D” or “state E” with many benefits of time-saving processing is transferred. That is, if the big win is won when the pachinko machine 1 is in a stalemate state, a gaming state advantageous to the player is likely to occur continuously, so that the expectation and game performance of the pachinko machine 1 can be further improved.

  As described above, in the pachinko machine 1 according to the present embodiment, as in the first embodiment, the setting of the time reduction condition for each gaming state using the gaming state table 100 and the probability variation execution number storage area 530b (probability) By controlling the probability cut-off variation using the remaining number of executions of fluctuation), the relief of the hamari state (preferential treatment of the hamari stand) and the preferential treatment in the initial state (giving a privilege at the time of resetting) are performed. More specifically, a certain degree of regularity is given to the transition of the gaming state due to the probability change of the number of cuts, and further, a time gap condition selected according to the gaming state at the time of jackpot state determination is provided with a gap. And, for one of the gaming states that change with a certain degree of regularity (here, “normal state (state A)”), by giving preferential treatment to the short-time processing privilege given to the gaming state after the jackpot, The highest game value is given both in the Hamari state and the initial state. In other words, when the big hit is made in the humming state or the initial state (that is, “state A”), the time-change probability changing state “state E” that is most advantageous for the player is executed. Therefore, in the pachinko machine 1 according to the present invention, there is no need to separately provide a counter for relieving the humorous state as in the prior art, and a privilege advantageous to the so-called hamari player only by controlling the gaming state as described above. Can be granted. Furthermore, not only granting a privilege to the Hamari table but also giving a privilege advantageous to a player of a so-called reset table can be realized at the same time.

  As described above, according to the pachinko machine 1 according to the second embodiment, the jackpot control is performed based on the jackpot random number acquired in response to the winning of the game ball to the special symbol starting electric accessory 15, The normal hit control is performed based on the normal hit random number acquired when the passage of the symbol start gate 12 is detected, and one of a plurality of game states “state A” to “state E” is selected and executed after the big hit state is finished. Therefore, the probability of selecting the game states “state B”, “state D”, and “state E” for executing the time-saving process among these game states is different based on the game state table 100.

  Then, after executing the jackpot state based on the probability variation jackpot, the game state always shifts to the probability variation (that is, “state C”, “state D”, or “state E”). Furthermore, when the number of changes in the special symbol becomes 300 times or more during execution of “state C” or “state E”, the state shifts to “state A” while the game state at the time of jackpot state determination is “state A” Has a high probability of shifting to the game state “state E” having the largest number of executions of the time-saving process after the jackpot state is ended.

  Therefore, by combining the gaming state table 100 and the number cut probability fluctuation to change the probability of executing the time-saving process after the jackpot state ends, it is possible to improve the gameability by providing a difference in the gaming values of a plurality of gaming states. it can. Furthermore, since the privilege of the short-time processing for the pachinko machine 1 that is in the humili state only by controlling the gaming state is preferentially given, the privilege of the short-time processing is given to the player of the so-called Hamari table with a simple configuration, and the player Can give a sense of expectation to the Hamari stand. In addition, when the pachinko machine 1 is reset to the initial state, it shifts to the “normal state”, so that the player can enjoy the game from the “normal state” in which the privilege of giving a short time is preferentially controlled. You can improve your interest in various ways.

  By the way, in the first and second embodiments, the special symbol start electric accessory 15 corresponds to the “start port” of the present invention, and the normal symbol operation switch 73 corresponds to the “detection means” of the present invention. The symbol display unit 24 corresponds to “ordinary symbol display means” of the present invention, and the gaming state table storage area 535 of the ROM 53 corresponds to “gaming state storage means” of the present invention.

  Further, in the main processing (see FIG. 10) of the pachinko machine 1, the CPU 51 that performs the special symbol processing (S9) shown in FIG. 11 performs the “big hit random number acquisition means”, “big hit determination means”, “game state selection” in the present invention. Functions as a means. The CPU that performs the special electric accessory processing (S7) shown in FIG. 12 functions as the “big hit state execution means” of the present invention. Further, the CPU 51 that performs the normal symbol processing (S15) functions as the “normal hit random number obtaining means” and the “normal hit determination means” in the present invention. The CPU 51 that performs the normal electric accessory processing (S13) corresponds to the “normal hit state execution means” in the present invention. The CPU 51 that performs the main process shown in FIG. 10 functions as the “game state control means” in the present invention.

  In addition, this invention is not limited to embodiment described in full detail above, A various change is possible. For example, in this embodiment, a pachinko machine that is a kind of gaming machine is given as an example of the gaming machine, but the gaming machine is not limited to a pachinko machine, and can be applied to various gaming machines such as a pachikon machine and a pachislot machine. is there.

  Further, in the first embodiment, the transition destination control of “state A” to “state C” is performed as the game state after the big hit, and “normal state”, “probability variation state”, “short-term probability variation state” ”Is controlled. Further, in the second embodiment, the transition destination control of “state A” to “state E” is performed as the game state after the big hit, and “normal state”, “normal state with time reduction”, “probability variation state” ”And“ Variable state with short time ”are controlled. However, the pachinko machine 1 may perform transfer destination control of 6 patterns or more, or may control a gaming state of 5 patterns or more. That is, the content and quantity of the gaming state controlled by the pachinko machine 1 can be arbitrarily applied. And the specification of the pachinko machine 1 can be easily changed by changing the definition content of the gaming state table 100.

  In addition, depending on the specifications of the pachinko machine 1, the jackpot probability in each gaming state, the number of executions of the time-saving process in the gaming state with a time saving, the number of executions of the probability variation for performing the frequency cut probability variation, etc. are arbitrary. Needless to say, it can be changed. For example, a large disparity may be provided in the jackpot probability between the normal state and the probability variation state as the normal state (jackpot probability: 1/300) and the probability variation state (jackpot probability: 3/300).

  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.
