Abstract

PROBLEM TO BE SOLVED: To provide a game machine for making it difficult to predict a timing, at which a state becomes advantageous for a player, but it possible for the player to continue the game for a long time period.SOLUTION: A time shortening state is advantageous for a player. Even if a bonanza is decided in a provability non-time shortening state (or state A), the ratio, at which the time shortening state is established, is low. If, however, the bonanza is decided in a non-provability non-time shortening state (or state B), the time shortening state is never failed to occur after the end of the jackpot game. If the failure is decided continuously 100 times in the state A, the game state shifts to the state B. Even in the case, however, where the bonanza is decided in the probability variation non-time shortening state (or state A), there may be the case, where the time shortening state is caused at a predetermined ratio after the time of the jackpot game.

Description

  The present invention relates to a gaming machine capable of shifting a gaming state to a state advantageous to a player by continuing a game and satisfying certain conditions.

  2. Description of the Related Art Conventionally, there is known a gaming machine that shifts a gaming state to a state advantageous to a player when the result of jackpot determination is a certain number of consecutive deviations. For example, the gaming machine described in Patent Literature 1 uses a function (so-called “number cutting probability changing function”) that terminates the probability variation state when a certain number of consecutive failures occur. When the probability variation state ends, the probability of being determined to be a jackpot decreases, but a time-short state is triggered by the determination of a jackpot. During the short-time state, the player may acquire a large number of game balls.

  In addition, a gaming machine is known that shifts a gaming state to a state advantageous to the player when a probability variation state occurs continuously for a certain number of times after the jackpot game ends (see, for example, Patent Document 2). This gaming machine uses a so-called limiter, which is a function that limits the number of consecutive occurrences of the probability variation state. Even if a jackpot occurs during the non-probability state, the time-short state is not generated. However, when a big hit occurs during the non-probability state, the time-short state occurs, and a large number of game balls are paid out.

  In a conventional gaming machine, a player can easily predict a condition that must be satisfied in order to shift to a non-stochastic fluctuation state, which is an advantageous state, and a transition timing. Therefore, if it is predicted that the transition condition is not satisfied unless the game is continued for a long time, the player loses the willingness to continue the game.

  It is an object of the present invention to provide a gaming machine that makes it difficult to predict the timing when the player is in an advantageous state and allows the player to continue the game for a long time.

The gaming machine according to claim 1, wherein a starting ball game ball detecting means for detecting a game ball won in a starting hole provided on the game board, and the starting ball game ball detecting means detects the game ball. Therefore, the jackpot random number acquisition means for acquiring the jackpot random number for determining whether or not to execute the jackpot game advantageous to the player, and the jackpot random number acquired by the jackpot random number acquisition means A jackpot judging means for judging whether or not a predetermined random number is determined, and a first opening / closing member, and a big winning opening that allows a game ball to be won only when the first opening / closing member is opened. A first opening / closing control means for opening and closing the first opening / closing member according to a predetermined opening / closing pattern during the jackpot game, and the jackpot determination means determines that the jackpot In this case, an opening / closing pattern determining means for determining the opening / closing pattern of the first opening / closing member during the jackpot game, which is executed in response to the determination, and a game ball that has passed through a passage opening provided on the game board are detected. And a normal hit for determining whether or not to execute a normal hit game advantageous to the player due to the detection of the game ball by the passport gaming ball detecting means. A normal hit random number acquisition means for acquiring a random number; a normal hit determination means for determining whether or not the normal hit random number acquired by the normal hit random number acquisition means is a predetermined random number determined in advance as a normal hit; A second opening / closing member that is provided on the game board and that is opened to facilitate winning of the game ball to the starting port, and the second opening / closing member is opened during the normal winning game. A second opening / closing control means, a non-probability fluctuation state in which a probability that the jackpot determination means is determined to be a big hit after the end of the jackpot game is a normal probability, and a probability that is determined to be a big hit is the non-probability fluctuation state A probability variation control means for generating any one of a probability variation state that is higher than the inside, a non-time-short state in which a rate at which the second opening and closing member is opened after the jackpot game is a normal rate, and the first When the ratio of opening the two open / close members is higher than that in the non-time-short state, the time-shortening control means that causes any one of the time-shortening states and the big-hit determination means determine that the big hit is made State determining means for determining a gaming state to be generated in the probability variation control means and the time-shortening control means after the jackpot game is completed; When the hit count is determined by the jackpot determination means after the winning game is finished, the probability counts when the number of times counted by the miss count count means reaches a first predetermined number. If the probability variation state has occurred by the variation control means, the probability variation end means for terminating the probability variation state and causing the non-probability variation state, and the number of times counted by the outlier count counting means are the second count. When the predetermined time is reached, if the time-short state has been generated by the time-shortening control means, the time-shortening means for ending the time-short state and causing the non-time-short state to be generated, and The opening / closing pattern includes a short-time opening / closing pattern in which the maximum opening time of the first opening / closing member during the jackpot game is a predetermined time, and the opening time. If there is a long-time opening / closing pattern whose maximum value is longer than that in the case of the short-time opening / closing pattern, and the time-short state has occurred when the jackpot determination means determines that it is a big hit, the non-time-shortening state is The ratio of the open / close pattern determining means to determine the long-time open / close pattern is higher than when the open / close pattern is determined, and when the jackpot determining means determines that the jackpot is big, the non-stochastic fluctuation state and the short-time state When at least one of them occurs, the state determination means causes the time-shortening control means to cause the time-shortening state compared to the case where neither the non-stochastic fluctuation state or the time-shortening state has occurred. high percentage of determining, the state determining means, when it is determined that the jackpot by the jackpot determining means, said non-stochastic variation Even if the state and the time-shortening conditions are not occurring any, characterized in that if there is to decide to rise to the time-shortening conditions to the time-shortening control means.

In the gaming machine, when the short-time state occurs, the rate at which the game ball wins at the start opening increases. Also, if it is determined that the game is a big hit during the short-time state, the player can easily acquire a game ball because the opening time of the first opening / closing member provided at the big winning opening tends to be long. Furthermore, if it is determined that the jackpot is during the time-short state, the time-short state is likely to occur again after the jackpot game ends. Therefore, the player plays the game while expecting to be in a short time state. Here, in the case of the probability variation state and the non-time-short state, even if it is determined that the jackpot is large, the rate at which the time-short state is subsequently generated is low. However, if the non-stochastic fluctuation state is entered, the rate at which the short-time state occurs is increased. In the big hit determination, if it is determined to be out of play for the first predetermined number of times, a non-stochastic fluctuation state is always obtained. Therefore, by continuing the game, a state in which the rate of occurrence of the short-time state is high (so-called “ceiling state”) is generated, so that the player's willingness to continue the game can be increased. Therefore, it becomes difficult for the player to determine when to stop the game. As a result, the gaming machine can be operated for a longer time. Further, in the gaming machine, even when the probability variation state and the non-time-saving state are generated, the time-saving state may be generated in response to the jackpot. Therefore, the player can continue the game while always expecting to be in a short time state.

  The gaming machine according to claim 2 is characterized in that, when initialized, the non-stochastic fluctuation state occurs. According to the gaming machine, the player can start a game while expecting the gaming machine to be initialized. That is, it is possible to increase the player's willingness to start a game and improve the operating rate of the gaming machine.

  According to a third aspect of the present invention, there is provided a gaming machine comprising notifying means for giving an effect of notifying the player of the gaming state, and notifying control means for controlling an effect mode by the notifying means, wherein the notifying control means is the game When the machine is initialized and the non-stochastic fluctuation state and the non-short-time state occur, the probability fluctuation control means and the time-short control means notify that the non-stochastic fluctuation state and the non-time-short state have occurred. It is characterized by controlling an effect different from the effect to be performed. In the gaming machine, it is not possible to determine whether or not the gaming machine is in a state after being initialized, depending on the effect of the notification means. Therefore, the player can start the game while more strongly expecting that the gaming machine has been initialized.

  The gaming machine according to claim 4, wherein the state determination means has the non-probability fluctuation state caused by the probability fluctuation control means, and the non-time reduction state is caused by the time reduction control means. When the jackpot determining means determines that the jackpot is big, the time-shortening control means causes the time-shortening state to occur.

  In this case, if a non-stochastic fluctuation state occurs and a non-temporal short state occurs, if the jackpot is reached, the short time state occurs. Therefore, the gaming machine can allow the player to continue the game for a long time.

  6. The gaming machine according to claim 5, wherein a limiter counting unit that counts the number of times that the probability variation state is continuously generated by the probability variation control unit, and the number counted by the limiter counting unit is a third predetermined number of times. When the jackpot game is over while reaching the above, the probability variation control means is provided with a probability variation number control means that always causes the non-probability variation state.

  In this case, if the probability variation state is continuously generated for the third predetermined number of times, the probability variation state is always set after the subsequent jackpot game. For this reason, it will be in a ceiling state if either of two conditions for becoming a ceiling state is satisfied. Thereby, the gaming machine can make it difficult for the player to grasp the timing of the ceiling state. Therefore, the gaming machine can be operated for a longer time.

  Hereinafter, a pachinko machine 1 which is an embodiment of a gaming machine according to the present invention will be described with reference to the drawings. First, the mechanical configuration of the pachinko machine 1 will be described with reference to FIGS. 1 to 3.

  As shown in FIG. 1, a game board 2 is provided in the upper half of the pachinko machine 1. The game board 2 is substantially square (see FIG. 2), and the front surface is protected by a glass frame 11 holding a transparent glass plate. In the lower part of the game board 2, an upper plate 5 is provided for supplying game balls to the launcher and receiving prize balls. A lower plate 6 for receiving a prize ball is provided immediately below the upper plate 5. On the right side of the lower plate 6, a launch handle 7 for adjusting the launch of the game ball is provided. Speakers 48 are respectively provided on the left and right corners of the upper portion of the glass frame 11. Furthermore, an illuminating device 35 is formed on the upper part of the glass frame 11 over substantially the entire length in the left-right direction.

  As shown in FIG. 2, a substantially circular game area 4 surrounded by a guide rail 3 is formed on the front surface of the game board 2. A symbol display device 8 is disposed substantially at the center of the game area 4. The symbol display device 8 includes a display screen 28 composed of an LCD, various lamps, LEDs, and the like. A normal symbol start gate 12 is provided on the left side of the symbol display device 8. Below the symbol display device 8, a special symbol start winning opening 15 is provided. An ordinary electric accessory 13 is provided below the special symbol start winning opening 15, and a large winning opening 18 is disposed below the normal electric accessory 13. Also, a state notification lamp 36 is provided near the right end of the game board 2 to notify the player of the gaming state when the power is turned on.

  The first opening / closing member 19 is provided in the big winning opening 18, and the game ball is placed in the big winning opening 18 only when the first opening / closing member 19 is opened (when the big winning opening 18 is opened). You can win a prize. Similarly, the normal electric accessory 13 is provided with a second opening / closing member 14, and the game ball is normally electric only when the second opening / closing member 14 is opened (when the normal electric accessory 13 is opened). You can win prizes 13 The first opening / closing member 19 and the second opening / closing member 14 are electrically opened and closed by a solenoid.

  As shown in FIG. 3, the symbol display device 8 includes a display screen 28 in the center. The display screen 28 displays various videos such as moving images and messages. In particular, the display screen 28 displays three demo symbols for informing the result of the jackpot determination. The pachinko machine 1 can also change the background screen of the demo symbol according to the gaming state that is occurring at that time. The symbol display device 8 includes a first special symbol memory number display LED 60 composed of four LEDs below the display screen 28. The first special symbol memory number display LED 60 is the number of game balls that have won the special symbol start winning opening 15 and the result of the first big hit determination is not yet displayed on the first special symbol display unit 25 (so-called “first” Display the number of special symbol operation reserve balls "). A second special symbol memory number display LED 61 is provided below the first special symbol memory number display LED 60. The second special symbol memory number display LED 61 indicates the number of game balls (the so-called “second special symbol actuated holding ball number”) that won the normal electric accessory 13 and for which the result of the second big hit determination has not been displayed yet. indicate.

  A first special symbol display unit 25 is provided on the left side of the second special symbol memory number display LED 61, and a second special symbol display unit 26 is provided on the right side. In the special symbol display portions 25 and 26, special symbols made up of alphabets, numbers, symbols, or combinations thereof are displayed. When a game ball wins the special symbol start winning opening 15, a first jackpot determination is performed, and one of a plurality of special symbols is displayed on the first special symbol display unit 25 according to the determination result. Further, when a game ball wins the ordinary electric accessory 13, a second jackpot determination is performed, and the determination result is displayed on the second special symbol display unit 26.

  The symbol display device 8 is provided with a normal symbol memory number display LED 59 composed of four LEDs above the display screen 28. Above the normal symbol memory number display LED 59, a normal symbol display unit 24 composed of one LED is disposed. The normal symbol display unit 24 indicates the state of the normal symbol and the result of the normal hit determination by turning on, turning off, and blinking. The normal symbol memory number display LED 59 is the number of game balls that have passed through the normal symbol start gate 12 and the normal symbol display unit 24 has not yet displayed the result of the normal hit determination (the so-called “normal symbol operation hold ball number”). Are displayed up to four.

  Next, a game flow in the pachinko machine 1 of the present embodiment will be schematically described. The pachinko machine 1 can cause a non-probability variation state with a probability of being determined as “big hit” in the first jackpot determination and the second jackpot determination, and a probability variation state with 1/30. In addition, it is possible to cause a non-short-time state in which the probability of being determined as “ordinary hit” in the normal hit determination is 1/100 and a short-time state in which 99/100 is set. Accordingly, the pachinko machine 1 can be combined with these “probability variation non-short-time state (state A = normal mode)”, “non-probability variation non-short-time state (state B = mode before time-short entry)”, “probability variation short-time state”. It is possible to cause four gaming states, “(State C)” and “Non-probability short time state (State D)”. The time-short state ends when the sum of the number of times of the first jackpot determination and the number of times of the second jackpot determination reaches a certain time-short number of times (80 times or 100 times), and shifts to a non-time-short state. When the sum of the number of jackpot determinations reaches 100, the probability variation state is terminated by the operation of a so-called number cut probability changing function. Note that the time-short state and the probability variation state are also terminated when it is determined that the jackpot.

  Next, the first jackpot determination will be described. When the game ball wins the special symbol start winning opening 15, a first jackpot determination is performed. If the result of the first jackpot determination is “big jackpot”, the big winning opening 18 is opened. However, as will be described in detail later, in 86% of the jackpot games that are executed with the first jackpot determination being determined as “big hit”, the winning prize opening 18 is opened only for a maximum of 0.2 seconds. The operation is only repeated four times. Therefore, it is difficult for a player to acquire a large number of game balls.

  When it is determined that the first jackpot determination is “big hit”, processing for determining a game state to be generated after the jackpot game ends is performed. Here, whether or not the probability variation state occurs is determined by whether or not the first special symbol determined at the time of determining the first jackpot is a probability variation symbol (whether or not the jackpot is a probability variation jackpot). The The rate at which the probability variation symbol is determined is 94%, and the rate at which the non-probability variation symbol is determined (the rate at which the non-probability variation jackpot) is 6%. However, if the probability variation state is a state in which the probability variation state is continuously generated 11 times every time it is determined to be a big hit by the first jackpot determination and the second jackpot determination, the function of limiting the number of consecutive occurrences of the probability variation state ( A so-called “limiter”) is activated and a non-stochastic variation state occurs regardless of the determined first special symbol.

  Whether or not the short-time state occurs is determined depending on the type of the first special symbol and the gaming state at the time when the jackpot is determined. Specifically, if the gaming state is not the “probability variation non-short-time state (state A = normal mode)”, the short-time state is always generated. In addition, if the special symbol of “long-time opening” in which the maximum opening time during one opening / closing operation of the grand prize winning opening 18 is 30 seconds is determined, the time-short state is surely generated.

  Next, the normal hit determination will be described. When the game ball passes the normal symbol start gate 12, the normal hit determination is performed. Whether or not it is a normal hit is determined by each probability (99/100 or 1/100) depending on whether or not a short-time state has occurred. The maximum opening time of the ordinary electric accessory 13 in the normal hit game is longer in the short-time state than in the non-short-time state. Furthermore, the variation time of the normal symbol displayed on the normal symbol display unit 24 is shorter in the short time state, and the normal electric accessory 13 is released after the normal symbol indicating the hit is fixedly displayed. Accordingly, the rate at which the ordinary electric accessory 13 is released during the game is significantly longer in the time-short state than in the non-time-short state.

  Next, the second jackpot determination will be described. When a game ball wins the opened ordinary electric accessory 13, a second jackpot determination is performed. The probability determined to be the second jackpot and the conditions for determining whether or not the probability variation state occurs are the same as in the case of the first jackpot. On the other hand, when it is determined as “big hit” in the second jackpot determination, a time-short state is always generated after the end of the jackpot game regardless of the second special symbol determined at the time of the second jackpot determination. Further, in the jackpot game that is executed when it is determined as “big jackpot” in the second jackpot determination, the maximum opening time during one opening / closing operation of the big winning opening 18 is always 30 seconds. In addition, when both the first special symbol operation reservation ball and the second special symbol operation reservation ball exist, the second big hit determination is preferentially executed. Therefore, when the gaming state becomes the “short state during probability change (state C)” or the “short state during non-probability change (state D)”, the winning of the game ball to the ordinary electric accessory 13 and the big winning opening 18 is in the non-short state. It becomes much easier than inside, and the player can acquire a large number of game balls. Furthermore, when a big hit is made during the short-time state, the short-time state is again generated after that, so that the short-time state and the big hit game are alternately continued, and a large number of game balls are paid out.

  As described above, in the pachinko machine 1, the player plays a game in the hope that a short-time state will occur. The gaming state has the highest ratio of “probability variation non-short-time state (state A = normal mode)”, but even if a big hit is made in state A, the rate of occurrence of a short-time state after that is small. However, when a big hit is made in the “non-stochastic fluctuation non-short-time state (state B = pre-short-time mode)”, a short-time state is always generated thereafter. The pachinko machine 1 can shift the gaming state to the state B by using the function of changing the number of cuts and the limiter. Since the player can change the gaming state to state B by continuing the game, the player continues the game for a long time. Further, the pachinko machine 1 realizes a so-called “ceiling state” by using two functions of the frequency cut probability change and the limiter, thereby making it difficult to grasp the timing of the ceiling state.

  Next, the electrical configuration of the pachinko machine 1 will be described with reference to FIG. As shown in FIG. 4, the control unit 40 includes a main board 41, a sub integrated board 58, a lamp driver board 46, an effect control board 43, a payout control board 45, and a relay board 47.

  The main board 41 controls the main control of the pachinko machine 1. The main board CPU unit 50 of the main board 41 is provided with a CPU 51 that performs various effects processing, a RAM 52 that temporarily stores data, and a ROM 53 that stores a control program and the like. An interrupt signal generation circuit 57 is connected to the main board CPU unit 50.

A display unit 26, a normal symbol memory number display LED 59, a first special symbol memory number display LED 60, and a second special symbol memory number display LED 61 are connected. The relay board 47 relays between these and the main board 41. The electric accessory opening solenoid 69 opens and closes the second opening / closing member 14 of the ordinary electric accessory 13 during the normal winning game. The big prize opening solenoid 70 opens and closes the first opening / closing member 19 of the big prize opening 18 during the big hit game. The normal symbol operation switch 74 detects a game ball that has passed through the normal symbol start gate 12. The big prize opening switch 75 detects a game ball won in the big prize opening 18.

  The power supply board 42 is connected to the main board 41 and the game ball launching device 37, and supplies DC stabilized power to each board and the game ball launching device 37. The game ball launching device 37 launches one game ball to the game area 4 at regular intervals (0.6 seconds in the present embodiment).

  Next, the storage area of the RAM 52 of the main board 41 will be described with reference to FIG. In the RAM 52, a counter storage area 5201, a winning ball flag storage area 5202, a normal hit relation information storage area 5203, a normal symbol operation reservation ball number storage area 5204, a first jackpot relation information storage area 5205, a first special symbol operation reservation ball A number storage area 5206, a second jackpot relation information storage area 5207, a second special symbol actuated holding ball number storage area 5208, a command relation storage area 5209, and a flag relation storage area 5210 are provided. The counter storage area 5201 stores various counters. The winning ball flag storage area 5202 stores a flag indicating whether or not a game ball has won the normal symbol starting gate 12 and each winning opening. The normal hit relation information storage area 5203 stores a random number acquired when winning a game ball to the normal symbol start gate 12. The normal symbol operation reserved ball number storage area 5204 stores the normal symbol operation reserved ball number. The first jackpot relation information storage area 5205 stores a random number that is acquired when a game ball is won in the special symbol start winning opening 15. The first special symbol operation reservation ball number storage area 5206 stores the first special symbol operation reservation ball number storage area 5206. The second jackpot relation information storage area 5207 stores a random number acquired when winning the game ball to the ordinary electric accessory 13. The second special symbol operation reserved ball number storage area 5208 stores the second special symbol operation reserved ball number. The command relation storage area 5209 stores control commands output from the main board 41 to other boards. The flag relation storage area 5210 stores various flags other than the flags stored in the winning ball flag storage area 5202.

  The counter storage area 5201 stores a random number acquisition counter, a timer counter, a limiter count counter, a big hit determination count counter, a winning ball counter, a round counter, and the like. The random number acquisition counter used in the following description mainly includes a first jackpot determination counter, a second jackpot determination counter, a first special symbol determination counter, a second special symbol determination counter, a first variation pattern determination counter, and a second variation There is a pattern determination counter. The value of the random number acquisition counter is incremented by a predetermined amount at regular intervals (4 ms) in the main process described later. The timer counter is a counter used for measuring time, and stores a predetermined value at the start of time measurement. In the main processing described later, the value of the timer counter is subtracted every 4 ms, and it is determined that a predetermined time has elapsed when the value becomes “0”. The limiter count counter is a counter that counts the number of consecutive occurrences of the probability variation state. The jackpot determination counter is a counter that counts the sum of the number of first jackpot determinations and the number of second jackpot determinations, and is reset when it is determined that the jackpot is determined. The winning ball counter is a counter that counts the number of game balls that have won the big winning opening 18. The round number counter is a counter that counts the number of times of opening / closing of the big prize opening 18 executed during the big hit game.

  The first jackpot relation information storage area 5205 of the RAM 52 will be described with reference to FIG. The first jackpot relation information storage area 5205 is used in a special symbol process (see FIGS. 9 to 13) of the main process described later. The first jackpot relation information storage area 5205 is provided with a determination area and first to fourth storage areas. And the random number which the 1st special symbol operation reservation ball acquired is memorized by the 1st-4th storage area. The determination area stores a result of the first jackpot determination that is currently being performed and a random number that is the basis of the jackpot game.

  Each of the determination area and the first to fourth storage areas is provided with a first jackpot random number column, a first jackpot special symbol determination random number column, and a first variation pattern determination random number column. The value of the first jackpot determination counter is stored in the first jackpot random number column. The value of the first special symbol determination counter is stored in the first jackpot special symbol determination random number column. The value of the first variation pattern determination counter is stored in the first variation pattern determination random number column. When a game ball wins the special symbol start winning opening 15, each value is stored in the storage area corresponding to the value of the number of first special symbol actuated balls. Based on the stored value, the first jackpot determination, the determination of the first special symbol when determined as the first jackpot, and the determination of the first special symbol variation pattern are performed. When the processing for the value stored in the determination area is completed, the value stored in the first storage area is shifted to the determination area, and processing such as the next first jackpot determination is performed based on this value. Accordingly, each value in the second to fourth storage areas is shifted to a young storage area with one number. Note that the configuration of the second jackpot relation information storage area 5207 is the same as the configuration of the first jackpot relation information storage area 5205, and thus the description thereof is omitted. Also, the normal hit relation information storage area 5203 is provided with four storage areas and one determination area, and stores random numbers acquired when winning a game ball to the normal symbol start gate 12.

  Next, the storage area of the ROM 53 of the main board 41 will be described. The ROM 53 stores various initial values, programs, and the like. Further, the ROM 53 includes a jackpot determination table for performing the first jackpot determination and the second jackpot determination, a special symbol determination table for determining the first special symbol and the second special symbol, and a variation for determining the variation pattern. Various tables such as a pattern determination table are stored.

  With reference to FIG. 7, the special symbol determination table and the correspondence between the game state at the time of jackpot and the game state after the jackpot game is ended will be described. The first jackpot special symbol and the second jackpot special symbol are each classified into one of a plurality of jackpot types. There are four types of first jackpot special symbols: “4R probability variation / short time release”, “4R probability variation / long time release”, “15R probability variation / long time release”, and “4R normal / short time release”. There are three types of special symbols for the second jackpot: “4R probability change / long-time release”, “15R probability change / long-time release”, and “4R normal / long-time release”. “4R” and “15R” indicate the number of times (the so-called “number of rounds”) that the big winning opening 18 is opened and closed during one big hit game. “Probability change” indicates a classification of probability variation symbols, and “Normal” indicates a classification of non-probability variation symbols. “Short time opening” indicates that the maximum opening time in one opening / closing operation of the special winning opening 18 is 0.2 seconds, and “Long time opening” indicates that the maximum opening time is 30 seconds. In the special symbol determination table, each special symbol and the value of the special symbol determination random number are associated with each other. When the jackpot is determined, a special symbol corresponding to the value of the special symbol determination random number is determined. Depending on the type to which the determined special symbol belongs, the number of rounds, the maximum opening time of the big winning opening 18, and after the end of the jackpot game The gaming state to be generated is determined.

  As a general rule, the game state generated after the end of the jackpot game is determined according to the game state generated at the time of the jackpot determination and the jackpot type to which the determined special symbol belongs. Specifically, whether or not to generate the probability variation state is determined depending on whether or not the special symbol is a probability variation symbol. Also, if the game state satisfies at least one of the two conditions that the game state is not “probability variation non-short state (state A = normal mode)” and the special symbol of the type of “long open”, A short-time condition occurs. Therefore, the player can enjoy the game while expecting that the gaming state does not become the state A. In addition, even when a game is played in the state A with the highest occurrence rate, it is a big hit of “long open” that can acquire a large number of game balls, or “4R normal / short open” that can shift to the state B You can play games while expecting a big hit.

  Here, in the pachinko machine 1, when it is determined that the first jackpot determination and the second jackpot determination are consecutively out of 100 times in the probability variation state, the function of changing the number of times is activated and the state shifts to the non-probability variation state. To do. Therefore, the state A becomes the state B when it is determined that the deviation is 100 consecutive times.

  In addition, the time-saving state is ended when it is determined that the predetermined number of time-savings is out of success in the first jackpot determination and the second jackpot determination. There are 80 times determined after the 4R jackpot game ends and 100 times determined after the 15R jackpot game ends. Therefore, when the number of time reductions is 80, the “probability fluctuation time-short state (state C)” is determined to be 80 times consecutively out of time, and the time-shortness state ends and “probability fluctuation non-time-short state (state A = Normal mode) ”. In this case, it becomes a disadvantageous state that it is difficult for the player to shift to the short time state, but since it has already been determined to be out of 80 consecutive times, if it is determined to be out of 20 consecutive times, it will move to state B To do. Moreover, if the second special symbol operation holding ball is stored during the time-shortening state, the time-shortening state is caused again by determining the second big hit immediately after the transition to the state A. Therefore, even when the state C ends, the player's expectation is not impaired. In addition, when the number of time reductions is 100, state C shifts to state B instead of state A because both the time reduction state and the probability variation state end when it is determined that the state C is disconnected 100 times continuously. When it is determined that the game is a big hit in state B, the time-short state is generated again. Therefore, the player can enjoy the game with the expectation that the number of time reductions will be 100 instead of 80. Further, the “non-stochastic fluctuation short state (state D)” shifts to the state B instead of the state A even if it is determined that there are 80 consecutive deviations. Therefore, the player can enjoy the game in the short-time state in the hope that the gaming state is not the state C but the state D.

  Furthermore, in the pachinko machine 1, even when the special symbol is a probability variation symbol, the probability variation state is continuously generated 11 times every time it is determined to be a jackpot by the first jackpot determination and the second jackpot determination ( If the number of consecutive jackpots based on the probability variation symbol is 12), the limiter is activated. As a result, the gaming state becomes “non-stochastic variation non-short time state (state B = pre-temporal mode entry)” or “non-probability short time state (state D)”. The limiter counting counter that counts the number of consecutive jackpots based on the probability variation symbol counts the number of consecutive times regardless of whether the short-time state has occurred or not in both the first jackpot judgment and the second jackpot judgment. To do. Therefore, the value of the limiter count counter can be increased while the short-time state and the jackpot game are alternately continued. As a result, it becomes extremely difficult to predict the timing of the operation of the limiter (the limiter reaches the ceiling), and the player can be motivated to continue the game.

  As described above, the pachinko machine 1 is provided with two ceilings, that is, the operation of the limiter (arrival of the limiter to the ceiling) and the operation of the frequency cut probability changing function (arrival of the frequency cut probability change to the ceiling). As a result, even if the player is expected to take a long time to reach the ceiling of the limiter, if the player is expected to reach the ceiling of the time-variable probability change, or if it cannot be predicted, Continue. Similarly, even if it is predicted that it will take a long time to reach the ceiling, the game is continued if the limiter is expected to reach the ceiling or cannot be predicted. That is, the pachinko machine 1 makes it difficult to predict the timing when the “non-probability variation non-short-time state (state B = pre-short-time entry mode)”, and allows the player to continue the game for a long time.

  Next, the operation of the main board 41 of the pachinko machine 1 will be described with reference to FIGS. The main control of the pachinko machine 1 is performed by a control program stored in the ROM 53. The main process of the control program is executed in the CPU 51 when the CPU 51 detects an interrupt signal generated every 4 ms by the interrupt signal generation circuit 57 (see FIG. 4). Hereinafter, each step of the flowchart is abbreviated as “S”. A process when the pachinko machine 1 is initialized will be described later with reference to FIG.

  First, command output processing is performed (S10). In the command output process, the control command is output to the sub-integrated board 58, the payout control board 45, the relay board 47, and the like. The control command output here is a control command stored in the RAM 52 in the main process executed last time.

  Next, a switch reading process is performed (S11). In the switch reading process, a process for detecting the winning of a game ball is performed from the detection results of the normal symbol start gate 12 and each switch (see FIG. 3) provided at each winning opening.

  Next, a counter update process is performed (S12). In the counter update process, the value of the random number acquisition counter stored in the RAM 52 is added, and the value of the timer counter is subtracted.

  Next, special electric accessory processing is performed (S13). In the special electric accessory process, a process for controlling the operation of the jackpot game and a process related to the game state that occurs after the jackpot game ends are performed (see FIGS. 14 and 15).

  Next, special symbol processing is performed (S14). In the special symbol processing, jackpot determination, determination of a special symbol, determination of a gaming state that occurs after the jackpot game ends, gaming state transition processing, and the like are performed (see FIGS. 9 to 13).

  Next, ordinary electric accessory processing is performed (S15). In the ordinary electric accessory process, a process for controlling the operation of the normal hit game is performed when the normal hit is reached. As described above, the CPU 51 opens the ordinary electric accessory 13 longer than in the non-time saving state if the time saving state has occurred. Note that the CPU 51 determines that the time reduction state is in effect if either the time reduction A flag or the time reduction B flag is set to “ON”.

  Next, normal symbol processing is performed (S16). In the normal symbol processing, a normal hit random number is acquired when the normal symbol operation switch 74 detects a game ball. Based on the acquired random number, processing such as ordinary hit determination, storage of commands for controlling fluctuations in ordinary symbols, and the like are performed. As described above, the probability (99/100) that is determined to be a normal hit during the short-time state is higher than the probability (1/100) that is determined to be a normal hit during the non-time-short state.

  Next, a payout process (S17), an error check (S18), and an information output process (S19) are performed. In the payout process, the payout of prize balls is controlled. In the error check, when an error occurs, the error is notified using the display screen 28, the speaker 48, and the like. In the information output process, various types of information are output to a game hall management computer (not shown).

  Next, the details of the special symbol process (S14) will be described with reference to FIGS. First, flags used in special symbol processing will be described. In the flag-related storage area 5210 (see FIG. 5) of the RAM 52, a jackpot gaming state flag, a special symbol display state flag, a probability variation flag, a time-short A flag, a time-short B flag, a probability variation winning flag, a time-short A winning flag, a time short B The winning flag and the like are stored. The jackpot game state flag is “ON” when “1” is stored during the jackpot game, and “0” is stored and “OFF” when the jackpot game is not played. The special symbol display state flag is “1” when either one of the two special symbol display portions 25 and 26 is changing (during change), and when one of them is stopped (during stop display). “2”, “0” is stored when neither of them is changing nor being stopped. The probability variation flag is set to “ON” by storing “1” during the probability variation state. The time reduction A flag is set to “ON” during the time reduction state where the time reduction count is 80 times. The time-short B flag is set to “ON” during the time-short state where the number of time reductions is 100 times. The probability variation winning flag is set to “ON” when it is determined that the probability variation state will occur after the jackpot game is over. The time-short A winning flag is set to “ON” when it is determined that 80 time-short states occur. The time-short B winning flag is set to “ON” when it is determined that the time-short state occurs 100 times.

  As shown in FIG. 9, when the special symbol process is started, it is determined whether or not a game ball is won in the special symbol start winning opening 15 (S21). When the start opening switch 72 provided in the special symbol start winning opening 15 detects winning of a game ball, the start opening switch 72 of the winning ball flag storage area 5202 is selected in the main process switch reading process (S11, see FIG. 8). The corresponding flag is set to “ON”. If this flag is not “ON” and the game ball has not won (S21: NO), the process directly proceeds to the determination of S25. If a game ball has won the special symbol start winning opening 15 (S21: YES), it is determined whether or not the value of the first special symbol operation reserved ball number storage area 5206 is "4" (S22). . If it is “4” (S22: YES), the number of suspendable balls that can be stored has reached the upper limit, and the process directly proceeds to the determination of S25.

  When the number of first special symbol operation reservation balls is not “4” (S22: NO), “1” is added to the value of the first special symbol operation reservation balls number storage area 5206 (S23). In the first jackpot relation information storage area 5205 (see FIG. 6), a random number is stored in a storage area having a number corresponding to the value of the first special symbol actuated ball number storage area 5206 (S24). Specifically, the value of the first jackpot determination counter is in the first jackpot random number column, the value of the first special symbol determination counter is in the first jackpot special symbol determination random number column, and the value in the first variation pattern determination random number column is Each value of the first variation pattern determination counter is stored.

  Next, processing related to winning a game ball to the ordinary electric accessory 13 is performed. First, it is determined whether or not a game ball has won the ordinary electric accessory 13 (S25). If the flag corresponding to the electric accessory switch 73 provided in the ordinary electric accessory 13 is “OFF” and it is determined that the game ball has not won (S25: NO), the processing is continued. The process proceeds to S31 (see FIG. 10). If a game ball has won the ordinary electric accessory 13 (S25: YES), it is determined whether or not the value of the second special symbol operation reserved ball number storage area 5208 is "4" (S26). If it is “4” (S26: YES), since the random number for this game ball cannot be stored, the process proceeds to the determination of S31 as it is.

  If the second special symbol operation reserved ball number is not “4” (S26: NO), “1” is added to the value of the second special symbol operation reserved ball number storage area 5208 (S27). Various random numbers are stored in the storage area of the second jackpot relation information storage area 5207 (S28), and the process proceeds to the determination of S31.

  Next, as shown in FIG. 10, it is determined whether or not the game state is a jackpot gaming state (S31). If the jackpot gaming state flag is “ON” and it is determined that the jackpot gaming state is in effect (S31: YES), the processing returns to the main processing as it is. If it is not in the big hit gaming state (S31: NO), it is determined whether any of the two special symbol display portions 25, 26 is changing (S32). If the display state flag is not “1” and neither of them is changing (S32: NO), it is determined whether or not one of the two special symbol display units 25 and 26 is stopped (S33). ). If the display status flag is not “2” and none of them are being stopped (S33: NO), the process proceeds to S34 (see FIG. 11), and a big hit determination is performed.

  In the jackpot determination, the second jackpot determination is performed with priority over the first jackpot determination. As shown in FIG. 11, first, it is determined whether or not the number of second special symbol operation holding balls is “1” or more (S34). If it is “1” or more and the second special symbol operation holding ball is present (S34: YES), the second jackpot determination is performed, which will be described in detail later. If the number of the second special symbol operation reservation balls is “0” (S34: NO), it is determined whether or not the number of the first special symbol operation reservation balls is “1” or more (S35). If it is “0” (S35: NO), the process directly returns to the main process.

  If the number of the first special symbol operation reservation balls is “1” or more (S35: YES), the value of the first special symbol operation reservation balls number storage area 5206 is subtracted from “1” (S36), and the first jackpot determination Is performed (S37). The first jackpot determination is performed based on the value in the first jackpot random number column of the first jackpot relation information storage area 5205 with reference to a determination table according to whether or not the probability variation state is in effect. If the determination result is a jackpot (S38: YES), one of the variation patterns indicating the first jackpot is determined by the value in the first variation pattern determination random number column (S39). According to the special symbol determination table (see FIG. 7), one of the first special symbols indicating the first jackpot is determined based on the value of the first jackpot special symbol determination random number column (S40). The process proceeds to S51. If the determination result is out of order (S38: NO), one of the variation patterns indicating the outage is determined (S41), and the process proceeds to S51. The special symbol in the case of a loss is one type of “-”.

  In addition, when the second special symbol operation holding ball exists (S34: YES), the second jackpot determination is performed in the same flow as the first jackpot determination. First, “1” is subtracted from the value of the second special symbol operation reserved ball number storage area 5208 (S43), and a second jackpot determination is made according to whether or not the probability variation state is being performed (S44). If it is a big jackpot (S45: YES), a variation pattern indicating that it is a second jackpot is determined (S46), and a second special symbol indicating that it is a second jackpot is determined (S47). The process proceeds to S51. If the determination result is out of order (S45: NO), the variation pattern indicating the out of place is determined (S48), and the process proceeds to S51. When the jackpot determination ends, a jackpot type determination process is performed (S51). In the jackpot type determination process, when the determination result is a jackpot, a game state that occurs after the end of the jackpot game is determined.

  With reference to FIG. 12, the jackpot type determination process will be described in detail. First, it is determined whether or not the result of the first jackpot determination or the second jackpot determination is a jackpot (S55). If it is not a big hit (S55: NO), the process returns to the special symbol process (see FIG. 11) as it is. If the determination result is a jackpot (S55: YES), depending on whether the determined special symbol type is “open for a long time” or “open for a short time”, the winning prize opening 18 of the jackpot game is determined. The maximum opening time and the number of rounds are determined (S56).

  If the type is “open for a long time” and “15R” (S57: YES), “1” indicates that a short-time state occurs when the number of time-savings is 100, regardless of the gaming state occurring at that time. "Is stored in the hourly B flag and is turned" ON "(S58), and the process proceeds to the determination of S65. If the jackpot type is not “15R” but “4R” (S57: NO), it is determined whether or not the type is “open for a long time” (S59). If the type is “open for a long time” (S59: YES), “1” indicating that the time-short state is generated is stored in the time-shortage A flag regardless of the gaming state (S60). ), The process proceeds to S65. If the jackpot type is “open for a short time” (S59: NO), it is determined whether or not a short-time state has occurred at that time (S61). If either the time-shortening A flag or the time-shortening B flag is “ON” and it is determined that the time-shortening state is in effect (S61: YES), the time-shortening A winning flag is set to “ON” (S60), The process proceeds to determination of S65. If not in the time-short state (S61: NO), it is determined whether or not a non-probability variation state has occurred at that time (S62). When the probability variation flag is “OFF” and it is determined that the non-probability variation state is in effect (S62: YES), the time reduction A winning flag is set to “ON” (S60), and the processing is determined in S65. Migrate to If the probability variation state is in effect (S62: NO), the processing shifts to the determination in S65 while both the time-short A winning flag and the time-short B winning flag are kept “OFF”.

  Next, it is determined whether or not the determined special symbol is a probability variation symbol (S65). If it is a probability variation symbol (S65: YES), it is determined whether or not the number of consecutive occurrences of the probability variation state has already reached the limit of 11 (S66). If the value of the limiter count counter that counts the number of consecutive occurrences of the probability variation state is less than “11” (S66: NO), “1” is added to the limiter count counter (S68). “1” indicating the occurrence of the probability variation state is stored in the probability variation winning flag to be “ON” (S69), and the process returns to the special symbol process. On the other hand, when the number of consecutive occurrences of the probability variation state has already reached 11 (S66: YES), the limiter is activated. That is, while the probability variation winning flag is set to “OFF”, the limiter count counter is initialized to “0” which is an initial value (S67), and the process returns to the special symbol process. If the determined special symbol is a non-stochastic variation symbol (S65: NO), the limiter count counter is initialized (S67), and the process returns to the special symbol processing.

  Returning to the description of FIG. When the big hit type determination process (S51) ends, the variation time of the special symbol determined according to the determined variation pattern is set in the special symbol variation time counter which is a timer counter (S52). “1” indicating that one of the special symbol display units 25 and 26 is changing is stored in the special symbol display state flag (S53), and the process returns to the main process.

  Further, in the determination of S32 shown in FIG. 10, when “1” is stored in the special symbol display state flag and it is determined that any of the special symbol display portions 25 and 26 is changing (S32). : YES), it is determined whether or not the variation time has elapsed (S71). If the value of the special symbol variation time counter set in S52 (see FIG. 11) is “0” and it is determined that the variation time has elapsed (S71: YES), a special symbol stop command is stored in the RAM 52. Is stored (S72). This command is transmitted to the sub-integrated board 58 and the relay board 47 in the next main process, and instructs the demo symbols on the display screen 28 and the fluctuation stop of the normal symbol display unit 24. Next, a predetermined stop display time (for example, 0.6 seconds) is stored in the special symbol stop time counter (S73). “2” indicating that one of the special symbol display units 25 and 26 is in a stopped display is stored in the special symbol display state flag (S74), and the process returns to the main process. On the other hand, if it is determined in S71 that the variation time has not yet elapsed (S71: NO), the process directly returns to the main process.

  If it is determined in S33 that “2” is stored in the special symbol display state flag and one of the special symbol display units 25 and 26 is determined to be stopped (S33: YES). Whether or not the stop display time has elapsed is determined based on the value of the counter set in S73 (S75). If the value of the special symbol stop time counter is not “0” and the stop display time has not yet elapsed (S75: NO), the process returns to the main process as it is. When the stop display time has elapsed (S75: YES), “0” indicating that neither the special symbol display units 25 and 26 are in the state of change nor stop display is stored in the special symbol display state flag (S76). . Next, a game state transition process is performed (S77), and the process returns to the main process.

  With reference to FIG. 13, the gaming state transition process will be described in detail. In the game state transition process, control of a flag for shifting to a jackpot game when it is determined that the jackpot is determined, and control of a flag for ending the short-time state and the probability variation state are performed. First, it is determined whether or not the result of the jackpot determination is a jackpot (S81). If it is a jackpot (S81: YES), the value of the jackpot determination count counter that counts the number of jackpot determinations made after the end of the previous jackpot game (number of times determined to be out of success) is initialized. (S82). “1” indicating that a jackpot game is being played is stored in the jackpot game state flag and set to “ON” (S83). The probability variation flag, the time reduction A flag, and the time reduction B flag are all set to “OFF” (S84). If the state notification lamp 36 is lit, it is turned off (S85), and the process returns to the main process. When the state of the pachinko machine 1 is initialized, the state notification lamp 36 is a lamp that indicates that the gaming state is “non-probability variation non-short-time state (state B = pre-short-time entry mode)”.

  If the result of the jackpot determination is out of place (S81: NO), “1” is added to the value of the jackpot determination count counter (S89). The counter is incremented regardless of whether the jackpot is the first jackpot or the second jackpot.

  Next, it is determined by the time-shortening A flag whether or not the time-shortening state is 80 times (time-shortening state A) (S90). If the time reduction A flag is “ON” and the time reduction state is 80 times (S90: YES), whether or not the number of determinations has reached 80 is determined based on the value of the jackpot determination count counter (S91). ). If it has not reached 80 times (S91: NO), the process returns to the main process as it is. When the number of times reaches 80 (S91: YES), the time reduction A flag is set to “OFF” (S92). In order to cause the sub-integrated board 58 to execute an effect indicating that the time-short state has ended, a continuous jackpot mode effect end command is stored in the RAM 52 (S93), and the process returns to the main process.

  If the number of time reductions is not in the time reduction state of 80 times (S90: NO), it is determined whether or not at least one of the time reduction state (time reduction state B) in which the time reduction number is 100 times and the probability variation state has occurred. (S95). If none has occurred (S95: NO), the process directly returns to the main process. If at least one has occurred (S95: YES), it is determined whether or not the number of jackpot determinations has reached 100 (S96). If it has not reached 100 times (S96: NO), the process directly returns to the main process. When it reaches 100 times (S96: YES), if the probability variation flag is set to “ON”, it is set to “OFF” (S97), and if the time reduction B flag is set to “ON”, “ "OFF" (S98). A ceiling arrival effect start command is stored in the RAM 52 in order to cause the sub-integrated board 58 to execute an effect indicating that the gaming state is the “non-probability variation non-short-time state (state B = pre-short-time entry mode)” (S99). ), The process returns to the main process.

  Next, with reference to FIG. 14 and FIG. 15, the details of the special electric accessory processing (see S13, FIG. 8) will be described. First, the flag used in the special electric accessory processing will be described. The main flags used here include an open flag and a processing standby flag. The opening flag is a flag indicating whether or not the special winning opening 18 is opened, and “1” is stored and “ON” is stored during opening, and “OFF” is displayed during closing. The process waiting flag is a flag indicating whether or not it is during a waiting time from when the special winning opening 18 is closed until the next processing relating to the special winning opening 18 is performed. "Is stored and" ON ".

  As shown in FIG. 14, when the special electric accessory processing is started, it is determined whether or not the jackpot gaming state is set (S101). If the jackpot gaming status flag is “OFF” and it is determined that the jackpot gaming status is not set (S101: NO), the processing returns to the main processing as it is. If it is determined that the game state is a big hit game state (S101: YES), it is determined whether or not it is during the waiting time until the next processing relating to the big winning opening 18 is performed by the processing waiting flag ( S102). When it is determined that the processing waiting flag is “OFF” and the waiting time is not being reached (S102: NO), it is determined whether or not the special winning opening 18 is opened (S103). When the open flag is “OFF” and the special winning opening 18 is closed (S103: NO), an opening command for opening the special winning opening 18 is stored in the RAM 52 (S104). Next, it is determined whether or not the jackpot type is “open for a short time” (S105). If it is “short-time opening” (S105: YES), a short-time opening counter for measuring a maximum opening time of 0.2 seconds is set (S106). If it is “long open” (S105: NO), a long open counter for measuring the maximum open time of 30 seconds is set (S107). Then, “1” indicating that the special winning opening 18 is open is stored in the open flag and is set to “ON” (S108).

  Next, it is determined whether or not the number of game balls won in the open big winning opening 18 is “9” or more (S110). The number of game balls won in the big winning opening 18 during one opening operation is counted in the switch reading process (S11, see FIG. 8). If the number of winning balls is not “9” or more (S110: NO), it is determined whether the maximum opening time of 0.2 seconds or 30 seconds has elapsed (S111). If the maximum opening time has not elapsed (S111: NO), the process returns to the main process as it is. In a special symbol process performed thereafter, if the game is a big hit game state (S101: YES), not during the waiting time (S102: NO), and the big prize opening 18 is open (S103: YES), These determinations are repeated until nine or more game balls win the winning opening 18 or until the maximum opening time elapses (S110: NO, S111: NO).

  If nine or more game balls are won (S110: YES), or if the maximum opening time has elapsed (S111: YES), a closing command for closing the opened big winning opening 18 is stored in the RAM 52. Stored (S112). The predetermined waiting time is stored in the processing waiting time counter (S113). The opening flag is set to “OFF” (S114). “1” indicating the waiting time is stored in the processing waiting flag and is set to “ON” (S115), and the processing returns to the main processing.

  If the processing standby flag is “ON” (S102: YES), it is determined whether or not the standby time has elapsed based on the value of the processing standby time counter (S118). If the value of the counter is not “0” and the standby time is being measured (S118: NO), the process directly returns to the main process. If time elapses while the main process is repeatedly performed and the standby time elapses (S118: YES), the process standby flag is set to “OFF” (S119). “1” is added to the round number counter that counts the number of opening / closing operations of the executed large winning opening 18 (S120).

  Next, whether or not the prescribed round has been consumed is determined based on the value of the round number counter (S121). The specified round is 4R or 15R, and is determined according to the special symbol determined at the time of jackpot determination. If the specified round has not been digested (S121: NO), the process returns to the main process, and the opening / closing operation of the big prize opening 18 is performed again in the special symbol process after the next time. When the value of the round number counter is “4” or “15” and it is determined that the specified round has been consumed (S121: YES), the value of the round number counter is initialized (S122). The jackpot gaming state flag is set to “OFF” (S123).

  Next, processing for generating a time-short state and a probability variation state is performed. First, it is determined whether or not the short time state A when the time reduction number is 80 or the short time state B where the time reduction number is 100 is won (S125). If both the time-short A winning flag and the time-short B winning flag are “OFF” and the time-short state has not been won (S125: NO), the process directly proceeds to the determination of S128. If the time-short A winning flag or the time-short B winning flag is “ON” (S125: YES), among the time-short A flag and the time-short B flag, the flag corresponding to the winning flag that is “ON” is set to “ON”. (S126). The time-short A winning flag or the time-short B winning flag that is “ON” is set to “OFF”.

  Next, it is determined whether or not the probability variation state is won (S128). If the probability variation winning flag is “OFF” and the probability variation state is not won (S128: NO), the process proceeds to S131. If the probability variation winning flag is “ON” (S128: YES), the probability variation flag is set to “ON” (S129), and the probability variation winning flag is set to “OFF” (S130). Next, an effect mode determination process is performed (S131), and the process returns to the main process. The effect mode determination process is a process of determining an effect mode such as the background of the demo symbol displayed on the display screen 28 according to the game state to be generated. By determining the production mode according to the gaming state, the gaming state that has occurred can be notified or suggested to the player.

  With reference to FIG. 15, the effect mode determination process will be described in detail. When the production mode determination process is started, first, it is determined whether or not a time-short state has occurred (S141). If it is during the short time state (S141: YES), a continuous jackpot mode effect start command is stored in the RAM 52 (S142). The continuous jackpot mode effect is an effect mode in which the player is notified that the short-time state and the jackpot gaming state are alternately continuous (continuous jackpot mode).

  If the short time state has not occurred (S141: NO), it is determined whether or not the probability variation state has occurred (S143). When the probability variation state has occurred, that is, in the case of the “probability variation non-short state (state A = normal mode)” (S143: YES), a limiter count counter that counts the number of consecutive occurrences of the probability variation state Depending on the value, the production mode is selected (S144). The production mode that can be determined here includes a normal production mode indicating that there is a high possibility of being in a “probability variation non-time reduction state (state A = normal mode)” and a “non-probability variation non-time reduction state (state B = time reduction). There is a chance effect mode that indicates that the possibility of the “pre-entry mode)” is higher than during the normal effect mode. The CPU 51 determines the normal effect mode with a higher probability as the value of the limiter counter is smaller, and determines the chance effect mode with a higher probability as the value of the limiter counter is larger. As a result, the player can play the game while expecting that the arrival to the state B is near by executing the chance effect mode. When the normal production mode is won (S145: NO), the normal production start command is stored in the RAM 52 (S146), and when the chance production mode is won (S145: YES), the chance production start command is stored. (S147). These commands are transmitted to the sub-integrated board 58 in the next main process. Thereafter, the process returns to the special electric accessory process.

  When the time-short state has not occurred (S141: NO) and the probability variation state has not occurred (S143: NO), that is, in the “non-probability variation non-time-short state (state B = mode before time-short entry)” In some cases, the production mode is selected (S151). In the production mode that can be determined here, in addition to the normal production mode and the chance production mode described above, there is a short-time-entry finalized production mode that indicates the state B. The probability that the lottery will be selected is the highest in the final effect before entering the short time and the lowest in the normal effect. Since the normal performance mode may be executed even during the occurrence of the state B, the player plays the game in the expectation that the state B is generated even when the normal performance mode is executed. It can be carried out. When the confirmed effect mode before entering the short time is won (S152: YES), a confirmed effect start command before entering the short time is stored in the RAM 52 (S153). When the chance effect is won (S152: NO, S154: YES), a chance effect start command is stored (S155). When the normal production mode is won (S152: NO, S154: NO), a normal production start command is stored (S156). Thereafter, the process returns to the special electric accessory process.

  Next, an initialization process performed by the main board 41 of the pachinko machine 1 will be described with reference to FIG. The initialization process is executed when the power is turned on next time by turning off the power while pressing a reset switch (not shown) provided on the back side of the pachinko machine 1. The initialization process is executed by the CPU 51 in accordance with the control program stored in the ROM 53, similarly to the main process described above. The main process is started after the initialization process is performed.

  In the initialization process, first, various data such as flags and counters stored in the RAM 52 are initialized (S161). Specifically, since the initial value of the probability variation flag is “0”, it is “OFF” even when the probability variation flag is “ON” before initialization. Similarly, the initial values of the time reduction A flag and the time reduction B flag are also “0”, both of which are initialized to “OFF”. As a result, the gaming state after initialization becomes a “non-stochastic variation non-short-time state (state B = mode before time-short entry)”. Next, a normal performance start command for instructing execution of the normal performance mode is stored in the RAM 52 (S162). Then, a process for turning on the state notification lamp 36 is performed (S163), and the initialization process ends. Although the status notification lamp 36 is a minute LED, it lights up when the pachinko machine 1 is initialized. Therefore, the player who knows the function of the state notification lamp 36 can start the game while paying attention to the state of the state notification lamp 36.

  Next, with reference to FIG. 17, the flow of the game in the pachinko machine 1 of the present embodiment will be described. In the pachinko machine 1, the gaming state having the highest percentage is the “probability variation non-short-time state (state A = normal mode)”. In the state A and the state B, the rate at which the ordinary electric accessory 13 is opened is very small, and the jackpot determination to be executed is almost the first jackpot determination. Therefore, state A and state B will be described assuming that the first jackpot determination is performed. On the other hand, during the time-short state, the rate at which the ordinary electric accessory 13 is opened is significantly higher than that during the non-time-short state. Further, the second jackpot determination is performed with priority over the first jackpot determination. As a result, most of the jackpot determination executed during the short-time state is the second jackpot determination. Therefore, the state C and the state D will be described on the assumption that the second jackpot determination is performed.

  The transition of the gaming state from state A will be described. In the state A, the probability of being determined to be a big hit is slightly higher (1/30) than in the “non-probability variation non-time-short state (state B = mode before time-short entry)”. The special symbol in the case of being determined to be a big hit has the highest rate of “4R probability change / short time release”, and the rate is 80%. When the big hit of “4R probability change / short time release” is made in state A, the gaming state after the big hit game is returned to state A in principle. That is, the state A is looped. In the state A, even if it is determined that the game is a big hit, the rate at which a player can acquire a large number of game balls is only 14%. Therefore, a large number of game balls cannot be acquired simply by looping through state A. However, if the number of consecutive occurrences of the probability variation state has reached 11 (if the limiter has been reached), the gaming state is “non-probability” even if the “4R probability change / short time release” jackpot in state A It shifts to the “variable non-short-time state (state B = mode before time-short entry)”. When a big hit is made in state B, a time-short state is always generated. Therefore, the player can enjoy the game in expectation of reaching the ceiling of the limiter.

  Further, if the big hit of “4R normal / short-time release” determined at a rate of 6% is made, the state shifts to the state B regardless of the value of the limiter count counter. Therefore, the player can expect to shift to the state B even when the arrival at the ceiling of the limiter is predicted to be slow. Furthermore, if it is a big hit of “4R / 15R probability change / long-time release” determined at a rate of 14%, the state A is directly shifted to the state C or D. Therefore, the player can enjoy the game while always expecting to enter the time-saving state. Even when the jackpot of “open for a long time” is reached, the ceiling function of the limiter operates in the same manner as the jackpot of “open for a short time”. Therefore, if the limiter is reached when the “long-term release” jackpot is reached, the gaming state shifts to the “non-probability short state (state D)”.

  Further, in the state A, when the deviation continues 100 times, the function of changing the number of times is activated. As a result, the state A shifts to the state B without going through the jackpot game. Therefore, the player can expect that the game content will be advantageous to him / her even if the big hit game is not executed for a long time. And even if the player plays a game hoping to reach the ceiling of probability change and reaches the ceiling, even if it becomes a big hit of “4R probability change / short time opening” before reaching the ceiling, Reach is near. On the contrary, as a result of playing a game in the hope of reaching the ceiling of the limiter, the ceiling may reach the ceiling of probability variation. As described above, the pachinko machine 1 makes it difficult to predict the timing of reaching the ceiling by providing two types of ceilings, and allows the player to continue the game for a long time.

  The transition of the gaming state from state B will be described. The probability of winning a jackpot in state B is lower than the probability of winning a jackpot in state A (1/35). However, when a big hit is made in state B, the state always shifts to state C or D. When transitioning to states C and D, the “long open” jackpot game and the short-time state may continue alternately. Accordingly, it can be said that the state B is more advantageous to the player than the state A. If the game state of the transfer destination is a jackpot (94%) in the probability variation symbol, in principle, it becomes the state C. However, when the limiter function is activated, the game state of the transfer destination is the state D. If it is a big hit (6%) in the normal symbol, the game state of the transfer destination becomes the state D.

  The transition of the gaming state from state C will be described. When a big hit is made in the “probability change short state (state C)”, the gaming state always shifts to the state C or D after the big winning game ends. That is, the short time state and the jackpot game are alternately continued. Therefore, the player plays a game in the hope that it will be a big hit during the short-time state.

  The time-short state includes a time-short state A of 80 times and a time-short state B of 100 times. If it is determined that the game is 80 times in the short time state A, the gaming state returns to the state A. When the big hit of “4R probability change / short time release” in state A, state A loops. However, at the time of transition from the short-time state A to the state A, the deviation is continued 80 times. That is, if the deviation continues for another 20 times, the gaming state immediately shifts to the state B by the function of changing the number of times. Therefore, the pachinko machine 1 causes the player to expect that it will be a big hit early in the short-time state A, and conversely, it will not expect a big hit immediately after the completion of the short-time state A. As a result, new game characteristics can be provided to the player. In addition, when the time-shifted state A shifts to the state A, the value of the limiter count counter may be 11 or a value close to 11. Furthermore, if the second special symbol actuated holding ball stored in the time reduction state A is a big hit, the time reduction state will occur again even immediately after the completion of the time reduction state A. As described above, the pachinko machine 1 can continue the game motivation without disappointing the player even when the time-short state A ends.

  In addition, 100 times, which is the number of time reductions in the time-shortening state B, is set to be equal to or more than the number of times of losing for the number cut probability change to operate. Therefore, even if it is determined that there are 100 consecutive discontinuations in the time reduction state B, and the time reduction state ends, the gaming state shifts to state B instead of state A. If a big hit is made in state B, the time-short state is generated again. Therefore, the player can enjoy the game in expectation that the time-short state B is generated rather than the time-short state A.

  The transition of the gaming state from state D will be described. If it is determined that the jackpot is determined in the “non-probability short time state (state D)”, the gaming state always shifts to the state C or D as in the case of the state C. Also, even if the jackpot is not determined while the state D is occurring, the gaming state shifts to the state B instead of the state A. Therefore, the state D becomes a gaming state that is most advantageous to the player among the four gaming states. The player can enjoy the game while expecting the gaming state to be in state D.

  As described above, in the pachinko machine 1 according to the present embodiment, the player can easily acquire a game ball by the occurrence of the short-time state. Furthermore, if it is determined that the jackpot is during the time-saving state, the time-shortening state is always generated again after the jackpot game is over. Therefore, the player plays the game while expecting to be in a short time state. Here, in the case of the “probability fluctuation non-short-time state (state A = normal mode)”, even if it is determined to be a big hit, the rate at which the short-time state is subsequently generated is low. However, if the “non-stochastic fluctuation non-temporal state (state B = pre-temporal mode)”, the short-time state is always generated in response to the jackpot. In the jackpot determination, if it is determined to be out of 100 consecutive times, a non-stochastic fluctuation state is always obtained. Further, when the number of consecutive occurrences of the probability variation state is 11, the non-probability variation state is always obtained after the subsequent jackpot game ends. Therefore, by continuing the game, a state in which the rate of occurrence of the short-time state is high (so-called “ceiling state”) is generated, so that the player's willingness to continue the game can be increased. Moreover, it will be in a ceiling state if either of two conditions for becoming a ceiling state is satisfy | filled. Therefore, it becomes difficult for the player to determine when to stop the game. As a result, the gaming machine can be operated for a longer time.

  When the pachinko machine 1 is initialized, the gaming state is always the state B. Therefore, the player can start the game while expecting the gaming machine to be initialized. That is, it is possible to increase the player's willingness to start a game and improve the operating rate of the gaming machine. Further, the pachinko machine 1 cannot determine whether or not the pachinko machine 1 is in a state after being initialized from the effects performed on the display screen 28. Therefore, the player can start the game while more strongly expecting that the gaming machine has been initialized.

  In the pachinko machine 1, when the time reduction state A is generated with the number of time reductions being 80 times, it is determined that it is a big hit after the time reduction state A ends and until the number of loss reaches 100 times. And there is a high possibility of a loop of state A. Therefore, the player expects to win a big hit early in the time-shortening state A, and expects that the discontinuity will continue immediately after the completion of the time-shortening state A. Therefore, even when the short-time state A ends, the player's interest is not impaired. Furthermore, when the time-short state B is generated when the time-shortening number is 100, even if the time-shortening state B is terminated after consecutive loss of time, the time-shortening state occurs again when the next big hit is determined. Is done. Accordingly, the game contents are further diversified, and the player can enjoy the game while expecting that the short-time state B is generated.

  In the pachinko machine 1, when the time-short state occurs, the rate at which the ordinary electric accessory 13 is opened increases. Therefore, the player can obtain an opportunity to execute the jackpot determination while receiving the game balls. When a game ball wins the ordinary electric accessory 13 and is determined to be a big hit, a time-shortened state is always generated after the big hit game ends. Since a large number of game balls are paid out in succession alternately in the short-time state and the jackpot game, it is possible to improve the player's expectation. Furthermore, even if the time-shortening state A ends, if the game ball has won the ordinary electric accessory 13 immediately before the completion of the time-shortening state A, and the winning ball stored by this winning wins, Is born. In other words, the short-time state is restored. Therefore, the player can continue the game with a strong sense of expectation even when the short-time state ends.

  In the pachinko machine 1, if it is determined that the jackpot is in the short-time state, the short-time state is always generated regardless of the distinction between the first jackpot and the second jackpot and regardless of the type of the special symbol. Therefore, there is no possibility that the continuation of the short-time state will be terminated on the way with a big hit. Therefore, the player can concentrate on the game while expecting only a big hit early without worrying about so-called punctures during the short-time state.

  In the pachinko machine 1, when it is determined that the jackpot is determined by the second jackpot determination, a short-time state is generated, and the jackpot type of “open for a long time” is always set. The ordinary electric accessory 13 is likely to be opened when a short-time state occurs. Therefore, the player is strongly expected that the short-time state will be generated, and can enjoy the game while paying close attention to the game contents such as the number of consecutive failures and the number of consecutive occurrences of the probability variation state. Moreover, in the pachinko machine 1, even in the state A, a time-short state may be triggered by a jackpot. Therefore, the player can continue the game while always expecting to be in a short time state.

  The present invention is not limited to the embodiment described in detail above, and it is needless to say that various modifications can be made without departing from the gist of the present invention. First, in the above-described embodiment, two types of jackpot determinations are employed, that is, a first jackpot determination and a second jackpot determination. Then, during the time-shortening state, the rate at which the second jackpot determination is executed is increased by making the rate at which the ordinary electric accessory 13 is opened higher than during the non-time-shortening state. As a result, it is easy to pay out a large number of game balls when it is determined to be a big hit during the time-short state. However, the present invention can be realized even if the jackpot determination and the number of special symbols employed are one.

  In the embodiment described above, the CPU 51 of the main board 41 determines the effect mode to be executed on the display screen 28 after the jackpot game ends. However, as a matter of course, the effect mode may be determined by another board such as the CPU 581 of the sub-integrated board 58.

  In the above-described embodiment, the continuous number of times of failure (100 times), which is a condition for operating the function of changing the number of cuts, is the same as the number of times of short-time state B (100 times). However, in order to make a direct transition from the short-time state B to the “non-stochastic fluctuation non-short-time state (state B = pre-short-time entry mode)”, the short-time number in the short-time state B is greater than or equal to the number of times that is the operating condition of the number cut probability change. It does not have to be the same value.

  It goes without saying that the various values described in the above embodiment are merely examples, and can be changed as appropriate. For example, the number of consecutive failures that become the operating condition of the number cut probability change, the number of consecutive occurrences of the probability variation state that becomes the condition for the limiter to operate, the probability that it is determined that the jackpot is determined to be a jackpot, the big winning mouth that is executed during the jackpot game The number of 18 opening / closing operations can be changed. Further, in the above embodiment, in order to realize a jackpot game in which a large number of game balls are paid out and a small jackpot game in which the game balls are paid out, a maximum opening time in one opening / closing operation of the big winning opening 18 is achieved. There are multiple types. However, the maximum opening time may be set to one type, and the difference in only the number of rounds may be used to provide a difference in the maximum opening time of the big winning opening 18 during one big hit game. In the above embodiment, the state notification lamp 36 is turned on at the time of initialization and is turned off at the start of the first jackpot game. However, it may be turned off at the time of initialization and turned on at the start of the first jackpot game.
