Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine provided with a variable winning opening having an opening / closing member.

  2. Description of the Related Art Conventionally, a gaming machine having a variable winning opening that allows a game ball to be won when an opening / closing member is opened is known. In this gaming machine, opening / closing of the opening / closing member is controlled according to a predetermined condition, and a predetermined number of game balls are paid out when a game ball wins a variable winning opening. That is, the number of game balls to be paid out is controlled by controlling the opening and closing of the opening and closing member.

  The opened opening / closing member is closed on condition that a predetermined number of game balls are won in the variable winning opening or on condition that a predetermined time has elapsed after the opening / closing member is opened. Here, the variable winning opening is provided with a proximity switch as a sensor for detecting a winning game ball. However, the time when the gaming ball actually enters the opened variable winning opening and the game ball by the proximity switch. There is a time difference from the time at which is detected. Therefore, in a gaming machine in which the opening / closing member is continuously opened / closed, if a sufficient time is not taken from the previous open state to the next open state, the detected game ball wins during the previous open state. It was not possible to determine whether it was a game ball that was played or a game ball that was won in a later open state. Therefore, in the conventional gaming machine, it is necessary to perform the next opening operation after a sufficient closing time has elapsed for the proximity switch to detect all the game balls that have entered the variable winning opening during one opening state. there were. However, during this closing time, it is impossible to win a game ball in the variable winning opening, so that the number of useless game balls that cannot be won increases and the number of game balls that a player can acquire has decreased. In addition, there is a difference in the number of game balls to be paid out between a player who stops launching game balls during the closing time and a player who continues launching.

Therefore, in addition to the opening / closing member, there has been proposed a gaming machine that includes a stopper door at an inward position of the opening / closing member, and that can stop the game ball on the opening / closing member that is open while the stopper door is closed. (For example, refer to Patent Document 1). In this gaming machine, the opening / closing member is always opened during the big hit gaming state, and the opening state and the closing state of the stopper door are repeatedly opened and closed, thereby separating the previous opening state and the subsequent opening state. When the stopper door is closed, the game balls are stopped on the opening / closing member, so that it is possible to reduce the number of useless game balls that cannot be won in the variable winning opening.
JP 2003-299804 A

  However, in the gaming machine described in Patent Document 1, when the stopper door is opened, in addition to the plurality of game balls that are stopped on the opening and closing member while the stopper door is closed, a game that newly enters the variable winning opening The ball will also flow toward the proximity switch at once. Therefore, there is a problem that the game ball may not be detected smoothly. In addition, there is a problem that it takes time to detect all the many game balls that have flowed in at one time.

  The present invention has been made to solve the above-mentioned problems, and while detecting game balls smoothly, the closed state of the variable prize opening is shortened as compared with the prior art, and wasteful game balls that cannot be awarded to the variable prize opening are obtained. An object is to provide a gaming machine that can be reduced.

  In order to achieve the above object, a gaming machine according to claim 1 is provided with a gaming board in which a gaming area in which gaming balls flow down is formed, an opening / closing member provided on the gaming board, and the opening / closing member. A first winning opening and a second winning opening that allow a game ball to be won when the opening is opened, and a winning opening opening / closing means that opens and closes the opening / closing member of the first winning opening and the opening / closing member of the second winning opening, A prize opening opening / closing control means for controlling the prize opening opening / closing means and opening / closing the opening / closing member of the first prize opening and the opening / closing member of the second prize opening alternately a predetermined number of times when a predetermined condition is satisfied; I have.

  In addition to the configuration of the invention described in claim 1, the gaming machine described in claim 2 of the present invention is a game ball launching means for continuously launching game balls to the game area at predetermined launch intervals. And when the opening and closing operation of the first prize opening and the opening and closing member of the second prize opening is performed alternately, after closing one opening and closing member that is opened, the other closed The time until the opening / closing member is opened is shorter than the firing interval of the game balls launched by the game ball launching means.

  Further, in the gaming machine according to claim 3 of the present invention, in addition to the configuration of the invention according to claim 1 or 2, the game ball flows down at the second winning opening from the position of the first winning opening. The winning opening opening / closing control means is provided upstream of the opening direction, and the opening / closing member of the first winning opening is opened before the opening / closing member of the second winning opening.

  According to a fourth aspect of the present invention, in addition to the configuration of the third aspect of the present invention, the winning opening opening / closing control means is configured to enable the first winning opening when the predetermined condition is satisfied. The opening / closing member and the opening / closing member of the second prize opening are both opened and closed once.

  A gaming machine according to claim 5 of the present invention is provided on the gaming board in addition to the configuration of the invention according to any of claims 1 to 4, and the first winning opening and the second winning prize are provided. A game ball guiding member for guiding the game ball toward the mouth is provided.

  In addition to the configuration of the invention according to claim 7, the gaming machine according to claim 8 of the present invention, in addition, when it is determined that the normal hit is determined by the normal hit determination means, next, the determination by the normal hit determination means Is performed by the jackpot determination means caused by all the game balls that have won the variable start opening with the opening and closing member opened, and when the jackpot determination means determines that the jackpot is determined to be a jackpot It is characterized by the fact that it is after all the jackpot states are finished.

  According to the gaming machine of claim 1, the game machine has a first and a second winning opening that has an opening / closing member and that allows a game ball to be won when the opening / closing member is opened, and a predetermined condition is established. In this case, the opening / closing member of the first winning opening and the opening / closing member of the second winning opening are alternately opened and closed a predetermined number of times. (Hereinafter, opening / closing the opening / closing member provided in the winning opening will be referred to as “opening / closing the winning opening”.) As a result, the other winning opening will open all winning game balls. Can be detected while Therefore, while smoothly detecting the game ball, the time from closing the winning opening once to opening the winning opening can be made shorter than when opening / closing one winning opening multiple times. Furthermore, the closing of one winning opening and the opening of the other winning opening can be performed simultaneously.

  In addition to the effect of the invention according to claim 1, the gaming machine according to claim 2 of the present invention further comprises a game ball launching means for launching game balls continuously into the game area at a predetermined launch interval. The time between the closing of one winning opening and the opening of the other winning opening is shorter than the launch interval of game balls launched by the game ball launching means. The frequency with which the number of useless game balls is two or more during the game can be reduced. In addition, since it is possible to prevent the so-called stop hitting, so that the launch of the game balls is interrupted intermittently for the purpose of reducing the number of useless game balls, the number of game balls to be paid out does not vary depending on the player. .

  In addition to the effect of the invention described in claim 1 or 2, the gaming machine according to claim 3 of the present invention has a first upstream side of the position where the first winning opening is provided in the flow direction of the game ball. A second winning opening is provided, and the first winning opening is opened before the second winning opening. Here, during the opening of the second winning opening provided upstream from the first winning opening, the game ball wins the second winning opening before reaching the first winning opening on the downstream side. It is difficult for a game ball to reach the vicinity of the big prize opening. Therefore, even if the downstream first winning opening is opened when the opened upstream second winning opening is closed, it is difficult for the game ball to win the first winning opening immediately after the opening. On the other hand, if the upstream second winning opening is opened when the opened downstream first winning opening is closed, the game ball is likely to win the second winning opening even immediately after opening. Accordingly, by opening the first winning port on the downstream side first, it is possible to smoothly win the game balls to the two winning ports.

  In addition to the effect of the invention according to claim 3, the gaming machine according to claim 4 of the present invention has both the first grand prize opening and the second big prize opening when a predetermined condition is satisfied. Since the opening and closing operations are performed one by one, the opening / closing operation to be executed is only a series of “lower and upper” operations, and the winning of the game balls to the two winning holes becomes smooth.

  A gaming machine according to claim 5 of the present invention, in addition to the effects of the invention according to any one of claims 1 to 4, is a game for guiding a game ball toward the first winning opening and the second winning opening. Since the ball guiding member is provided, it is possible to reduce the frequency of occurrence of useless game balls that cannot be won in the winning opening. Further, even when the opening times of the two winning awards are set short, the game balls are likely to win the winning award.

  In addition to the effect of the invention according to any one of claims 1 to 5, the gaming machine according to claim 6 of the present invention is a big hit due to the winning of a game ball at a specific starting port. A jackpot determining means for determining whether or not the jackpot determining means alternately opens and closes the first winning port and the second winning port a predetermined number of times so that the winning jack is opened during the jackpot state. The frequency with which useless game balls that cannot be won can be reduced. Accordingly, since the number of game balls to be paid out when it is determined to be a big hit is larger than a gaming machine in which one winning opening is continuously opened and closed several times, it is possible to increase the player's expectation for the big win.

  In addition to the effect of the invention according to claim 6, the gaming machine according to claim 7 of the present invention is a variable starting port in which the specific starting port has an opening / closing member, and a game ball to the specific passing port A normal hit determining means for determining whether or not the normal hit is caused by the passing of the game is provided, and when it is determined that the normal hit, the opening and closing member of the variable start port is opened to enable the winning of the game ball. Then, a jackpot determination is made in response to the winning of a game ball at the variable start opening, and when it is determined that the jackpot is reached, the two winning openings can be alternately opened and closed a predetermined number of times.

  The gaming machine according to claim 8 of the present invention, in addition to the effect of the invention according to claim 7, when the normal hit determination means determines that it is normal hit, the next determination by the normal hit determination means. The time to be played is after the judgment by the jackpot judging means for all the game balls that have won the variable prize opening and the jackpot state that occurs when the judgment result of whether or not the jackpot is a jackpot are completed. Therefore, the determination by the normal hit determination means is not performed during the jackpot determination or during the jackpot state. Therefore, the series of jackpot determination and jackpot game performed when it is determined to be a normal hit and the series of jackpot determination and jackpot game performed when it is determined to be a normal hit next time do not overlap. A person can acquire a game ball efficiently.

  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.

A second big prize opening 17 is provided below the symbol display device 8, and a first big prize opening 16 is provided below the second big prize opening 17. Note that the ordinary electric accessory 13, the first big prize opening 16, and the second big prize opening 17 are provided with opening / closing members that are opened at a predetermined timing. The game ball can be won only when the opening / closing member is opened (when the ordinary electric accessory 13, the first grand prize opening 16, and the second big prize opening 17 are opened). The game ball cannot be won at the time of closing (when the ordinary electric accessory 13, the first grand prize opening 16, and the second big prize opening 17 are closed). Further, the normal winning openings 18, 19, and 20 are provided on the left side of the first big winning opening 16, and the normal winning opening 21 is provided on the right side.

  A game ball guiding member 22 is provided on the left side of the second grand prize winning port 17. The game ball guiding member 22 is a synthetic resin member having a left-right direction as a longitudinal direction, a flat plate extending from the game board 2 toward the front side, and a decorative plate extending upward from the front side end of the flat plate. Consists of. The game ball guiding member 22 is disposed such that the flat plate is inclined downward from the ordinary electric accessory 13 toward the second big prize opening 17. Accordingly, the game ball that has reached the upper surface of the flat plate in the game ball guiding member 22 does not move more irregularly than the case where a plurality of game nails are arranged side by side, and the two big winning holes 16, 17 Move smoothly toward. In addition to the above, the game board 2 is provided with various illumination lamps, other illumination LEDs, a windmill, a number of game nails, and the like.

  Next, the symbol display device 8 will be described with reference to FIG. As shown in FIG. 3, the symbol display device 8 has a display screen 28 in the center. Various images such as moving images and messages are displayed on the display screen 28. In particular, in order to notify the result of the normal hit determination, the demo symbol display unit D1 is arranged on the display screen 28 side by side, left, right, and center. There are provided three display areas, a demo symbol display part D2 and a demo symbol display part D3. And the demo symbol display parts D1-D3 occupy the area wider than the below-mentioned normal symbol display part 24 and the special symbol display part 25 so that a player's eyes may be attracted.

  Further, the symbol display device 8 is provided with a normal symbol memory number display LED 59 consisting of four LEDs below the display screen 28, and a normal symbol display unit 24 consisting of one LED is provided on the right side thereof. ing. In the normal symbol display unit 24, the lighting state indicates normal winning, the unlit indicates normal winning, and the blinking state is a fluctuating state indicating that the determination result of the normal winning determination will be notified from now on. Yes. Further, the normal symbol memory number display LED 59 passes through the normal symbol start gate 12 (see FIG. 2), and the number of game balls whose normal hit determination result is not yet displayed on the normal symbol display unit 24, so-called normal symbols. The number of operation holding balls is displayed by the number of LEDs to be lit.

  In addition, the symbol display device 8 is provided with a special symbol memory number display LED 60 composed of four LEDs above the display screen 28, and above that a special symbol display unit 25 composed of two seven segments. Is provided. The special symbol display unit 25 displays a special symbol consisting of alphabets and numbers that can be displayed in 7 segments, or a combination thereof. For this special symbol, a “bonus special symbol” and a “offset special symbol” are predetermined for each combination, and the “bonus special symbol” is further provided with a “probability variation symbol” and a “non-probability variation symbol”. ing. Also, the special symbol memory number display LED 60 wins the ordinary electric accessory 13 (see FIG. 2), and the number of game balls for which the result of the big hit determination is not yet displayed on the special symbol display unit 25, so-called special symbol operation suspension. The number of balls is displayed by the number of LEDs that are lit.

  Here, the game and effect in the pachinko machine 1 of this Embodiment are demonstrated. In the pachinko machine 1, when the game ball passes the normal symbol start gate 12, the normal hit determination is performed. In the present embodiment, it is possible to cause a non-short-time gaming state in which the probability of being determined to be “winning” in the normal hit determination is 5/719, and a short-time gaming state in which 718/719 is established. If the determination result of the normal hit determination is “winning”, the pachinko machine 1 is in the normal hit state, the normal electric accessory 13 is opened, and the game ball can be won in the normal electric accessory 13. Become. The ordinary electric accessory 13 is closed when a predetermined time (4.5 seconds) elapses or when five game balls are won. Here, the determination result of the normal hit determination is displayed on the normal symbol display unit 24 and further displayed on the demo symbol display units D1 to D3 of the display screen 28. The demo symbol display units D1 to D3 are configured to attract the player's eyes more than the normal symbol display unit 24, and are further synchronized with the effects of the background screen of the display screen 28, the lighting device 35, the speaker 48, and the like. Thus, the result of the normal hit determination is informed to increase the player's interest and expectation.

  Next, when a game ball wins the ordinary electric accessory 13, a jackpot determination is performed. In the present embodiment, it is possible to cause a normal state in which the probability of determining “big hit” in jackpot determination is 2009/2011 and a probability variation state in which 2010/2011 is set. If the determination result of the jackpot determination is “Big Jack”, the pachinko machine 1 is in the jackpot gaming state, and the jackpot game in which the first big winning opening 16 and the second big winning opening 17 are sequentially opened once is executed, The game ball is ready to be awarded to the first grand prize opening 16 and the second big prize opening 17. The first grand prize opening 16 and the second big prize opening 17 are both closed when a predetermined time has elapsed or one game ball has been won. Therefore, every time it is determined as “winning” once by the normal hit determination, a maximum of 5 jackpot games are played.

  In this embodiment, the winning prize openings 16 and 17 are alternately opened once in a single jackpot game, that is, a two-round opening operation is performed. The number of rounds played can be changed. In this case, the two big prize winning openings 16 and 17 are alternately opened repeatedly until the number of times the opening operation is performed becomes equal to the set number of rounds. As described above, the determination result of the jackpot determination is displayed on the special symbol display unit 25.

  Further, when it is determined that the jackpot is “big jackpot”, it is determined whether the jackpot is a probability variation jackpot or a non-probability variation jackpot. The probability determined to be a probability variation jackpot is 81/84. If it is determined that the probability variation jackpot, the probability variation state and the short-time gaming state that continue until the stop display time after the next special symbol variation ends are simultaneously generated after the jackpot gaming state ends. On the other hand, when it is determined that the non-probability variation jackpot, the above-described normal state and non-short-time gaming state are caused.

  Accordingly, when it is determined as “winning” in the normal winning determination and the game ball wins the normal electric accessory 13, it is determined as “big hit” with a probability of 2009/2011 or 2010/2011. And if this jackpot is a probability variation jackpot determined with a probability of 81/84, and if a normal hit determination is made during the subsequent short-time gaming state, the next immediately with a probability of 718/719 Normal hit games and a maximum of 5 big hit games will be played. That is, a normal hit game and a jackpot game are continued. Details of this will be described later with reference to a flowchart.

  Here, hitherto, it was determined to be a big hit in the old type 1 game machine that can shift to a high probability state where the probability of being determined to be a big hit (hereinafter referred to as “big hit probability”) is higher than the normal state. If it shifts to a high probability state at that time, it is easy to determine that it is a big hit compared to the normal state. In addition, gaming machines sold in recent years tend to have a higher probability of shifting to a high-probability state than before when determined to be a big hit. However, if the probability of going to a high probability state is increased instead of making the jackpot probability in the normal state extremely low, or if the jackpot probability is extremely high when entering the high probability state, There is a risk that the game balance will be lost. Therefore, in the old type 1 gaming machine, there is a regular restriction such that the jackpot probability in the high probability state is up to 10 times the jackpot probability in the normal state (for example, JP-A-11-33178). Issue). In other words, when the jackpot probability in the high probability state is set high (for example, one tenth), the jackpot probability in the normal state is also set accordingly. (For example, 1/100) must be set higher (for example, 1/100).

  Thus, the higher the jackpot probability in the high probability state, the higher the jackpot probability in the normal state must be increased. In this case, in order to balance the game, one jackpot game The number of game balls that a player can acquire must also be reduced. Such a type of gaming machine corresponds to a gaming machine called “Hanedegi” which has a high jackpot probability by reducing the average number of game balls acquired during a jackpot game. Such a gaming machine becomes a jackpot game relatively easily, but it is difficult to acquire a large number of game balls in one jackpot. Moreover, although the jackpot probability in the high probability state is higher than the jackpot probability in the normal state, on average, if a lottery is not performed for the number of times corresponding to the probability, the jackpot game will not occur. Therefore, unless a jackpot game with a small average number of game balls is digested a plurality of times in a discontinuous manner, a player cannot acquire a large number of game balls. That is, the increase in the number of game balls acquired by the player is slow, and the gameability lacks sharpness. Therefore, there are some points that are apt to be avoided by players who seek moderate euphoria.

  Therefore, the gaming machine according to the present embodiment continuously generates a plurality of jackpot games without losing the game balance, and reduces the number of useless game balls that cannot be won at the winning opening during the jackpot game. So, it ’s a great game.

  Next, the storage area of the RAM 52 of the main board 41 will be described with reference to FIG. FIG. 5 is a conceptual diagram showing a storage area of the RAM 52. As shown in FIG. 5, the RAM 52 stores a counter storage area 5201 for storing various counters, a winning ball flag storage for storing a flag indicating whether or not a game ball has won a normal symbol starting gate 12 or each winning opening. Area 5202, normal winning relation information storage area 5203 for storing a random number acquired when winning a game ball to the normal symbol start gate 12, normal symbol operation reserved ball number storage area 5204 for storing the normal symbol operation reserved ball number, normal Sub-integration from the main board 41, a jackpot related information storage area 5205 for storing random numbers acquired when winning a game ball to the electric accessory 13, a special symbol operation reserved ball number storage area 5206 for storing a special symbol operation reserved ball number Control commands output to the board 58, the payout control board 45, the electrical board 46, the relay board 47, the game hall management computer 90, etc. Command relation storage area 5207 for storing the flag relation storage area 5208 for storing various flags are provided. Further, the RAM 52 is provided with various storage areas not shown.

  Next, each counter stored in the counter storage area 5201 of the RAM 52 will be described. The counter stored in the RAM 52 includes a random number acquisition counter for acquiring a random number, a timer counter for measuring time, a winning ball counter for counting the number of winning balls, and the like.

  First, the random number acquisition counter will be described. As the random number acquisition counter, there are a normal hit determination counter, a big hit determination counter, a hit special symbol creation counter, a lost special symbol generation counter, a variation pattern determination counter, and the like. The values of these counters are set at regular intervals (for example, in the counter update process (S12, see FIG. 8) of the main process executed based on the interrupt signal from the interrupt signal generating circuit 57 (see FIG. 4). Then, a predetermined amount (for example, “1”) is added every 2 ms which is an interval of interrupt signal generation. Each counter is provided with a minimum value (lower limit value) and a maximum value (upper limit value), and is configured to circulate within a numerical value in a range from the minimum value to the maximum value. In other words, if the counter value becomes the same as the maximum value as a result of the update, the counter value takes the minimum value in the next update. In each random number acquisition counter, “0” is stored as an initial value when the pachinko machine 1 is activated. When the value is rounded to the same value as the initial value “0” by updating, a new initial value is set. Acquired, and “1” is added to the initial value. This new initial value is repeatedly executed while the CPU 51 does not perform the main process (see FIG. 8) (until the main process ends and a new main process is started by an interrupt signal). A random number generated by an initial value random number process (a process for generating a random number by a predetermined algorithm) not shown is used.

  For example, the maximum value of the normal hit determination counter used for determining the normal hit is “719”, and the minimum value is “0”. Then, “1” is added every interrupt (every 2 ms), and when it becomes “720” or more, it returns to “0”. When the random number generated last time by the initial value random number processing is “18”, “0” is added to “1”, “2”, and when it becomes “18”, a new one is added. An initial value is acquired, and “1” is added to the initial value. These random number acquisition counters are used in normal symbol processing (see FIGS. 9 and 10) and special symbol processing (see FIGS. 12 and 13) of the main process described later.

  Next, the timer counter will be described. The timer counter is a counter used for measuring time, and a predetermined value is stored as an initial value at the start of time measurement. For example, when measuring 1 second, “500” is stored as an initial value. Then, “1” is subtracted by “1” in the counter update process (S12, see FIG. 8) performed every 2 ms, which is the interval of interrupt signal generation, and it is determined that the time is being measured unless the value is “0”. When the value becomes “0”, it is determined that a predetermined time has elapsed. The value of the timer counter is programmed not to be updated after it becomes “0”. Although a large number of timer counters are used in this embodiment, the description of each timer counter will be described later.

  Next, the winning ball counter will be described. In this embodiment, an ordinary electric accessory winning ball counter is used as the winning ball counter. The value of the number of winning counters for the ordinary electric accessory winning ball counts the number of game balls won to the ordinary electric accessory 13 while the opening / closing member provided in the ordinary electric accessory 13 performs one opening / closing operation. Used for. Then, when the value of the normal electric accessory winning ball counter reaches 5 or more, or when a predetermined time elapses, the normal electric accessory 13 is closed. The initial value of the normal electric accessory winning ball counter is “0”, and every time a game ball wins the ordinary electric accessory 13 in the switch reading process (S11, see FIG. 8) of the main process described later, 1 ”is added.

  Next, the normal hit relation information storage area 5203 will be described with reference to FIG. FIG. 6 is a conceptual diagram showing the ordinary hit relation information storage area 5203 of the RAM 52. This normal hit relation information storage area 5203 is used in the normal symbol processing (see FIGS. 9 and 10) of the main processing described later. As shown in FIG. 6, the normal hit relation information storage area 5203 is provided with a determination area, a first storage area, a second storage area, a third storage area, and a fourth storage area. In the first to fourth memory areas, random numbers obtained by the game balls (ordinary symbol operation holding balls) that have passed through the normal symbol start gate 12 and have not yet been notified of the determination result of the normal hit determination are stored. . In the determination area, a result of the normal hit determination currently being performed and a random number based on the normal hit game are stored. Each of the determination area and the first to fourth storage areas is provided with a normal hit random number column and a variation pattern determination random number column, and the normal hit random number column stores the value of the normal hit determination counter, and the variation pattern The value of the variation pattern determination counter is stored in the determined random number column.

  When it is confirmed that the game ball has passed through the normal symbol start gate 12 in the normal symbol processing, the value of the normal symbol operation reserved ball number storage area 5204 in the first memory area to the fourth memory area. Two values are stored in the storage area of the number corresponding to (ordinary symbol operation holding ball number). For example, if the number of normal symbol actuated balls is “3”, it is stored in the third storage area. Then, when the processing for the value stored in the determination area is completed, the next processing for the number of normal symbol actuated balls is performed. Accordingly, the value stored in the first storage area is shifted to the determination area, and the jackpot determination result is notified based on the value stored in the determination area. In addition, as the first storage area is shifted to the determination area, each value in the second to fourth storage areas is shifted to a young storage area with one number, and the value in the fourth storage area is cleared. Here, the number of storage areas is four. In other words, for the game ball that has passed through the normal symbol start gate 12, the number of random numbers that can be stored and the operation can be suspended is four. Therefore, the upper limit of the number of normal symbol operation reserved balls is four, and the value of the normal symbol operation reserved ball number storage area 5204 does not take a value larger than “4”.

  Next, the jackpot relation information storage area 5205 will be described with reference to FIG. FIG. 7 is a conceptual diagram showing the jackpot relation information storage area 5205 of the RAM 52. The jackpot relation information storage area 5205 is used in a special symbol process (see FIGS. 12 and 13) of the main process described later. As shown in FIG. 7, the jackpot relation information storage area 5205 is provided with a determination area and first to fourth storage areas in the same manner as the ordinary hit relation information storage area 5203 described above. In the area, a random number acquired for a game ball (the number of special symbol actuated suspension balls) that has won the ordinary electric accessory 13 and has not yet been notified of the result of the jackpot determination is stored. The determination area stores information on the results of the jackpot determination that is currently being performed and random numbers that are the basis of the jackpot game.

  In each of the determination area and the first to fourth storage areas, a jackpot random number field in which the value of the jackpot determination counter is stored, a special symbol determination random number field in which the value of the hit special symbol creation counter is stored, and a special off-set symbol A special symbol determining random number field for storing the value of the creation counter is provided. Then, when the winning of the game ball to the ordinary electric accessory 13 is confirmed, each value is stored in the storage area corresponding to the value of the special symbol operation reservation ball number storage area 5206 (special symbol operation reservation ball number), Based on this value, jackpot determination and notification of the determination result are performed.

  Next, details of the operation of the main board 41 of the pachinko machine 1 according to the present embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 8 is a flowchart of the main process in the main board 41. FIGS. 9 and 10 are flowcharts of a subroutine of normal symbol processing performed in the main process, and FIG. 11 is a flowchart of a subroutine of normal electric accessory processing performed in the main process. 12 and 13 are flowcharts of a subroutine of special symbol processing performed in the main process, and FIG. 14 is a flowchart of a subroutine of special electric equipment processing performed in the main process. Hereinafter, each step of the flowchart is abbreviated as “S”.

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

  First, main processing performed on the main board 41 will be described with reference to FIG. As shown in FIG. 8, when the main process is started by sensing an interrupt signal, a command output process is first performed (S10). In this command output process, a control command is output to the sub-integrated board 58, the payout control board 45, the electrical decoration board 46, the relay board 47, etc. via the I / O interface 54. The control command includes a command for instructing the determined normal symbol variation pattern, a command for instructing the timing for stopping the ordinary symbol, a command for instructing the opening / closing timing of the ordinary electric accessory 13, and start / stop of special symbol variation. There are a number of commands, such as a command for instructing the opening / closing timing of the first grand prize winning port 16 and the second major winning prize port 17, and the details thereof will be described later. The control command output here is a control command stored as an output command in the command relation storage area 5207 in the main process executed last time.

  Next, a switch reading process is performed (S11). In this switch reading process, a process of detecting the winning of a game ball in the normal symbol starting gate 12, the ordinary electric accessory 13, the first grand prize winning port 16, the second major prize winning port 17, and the normal winning prize ports 18 to 21 is performed. Is called. Specifically, the normal symbol operation switch 73 provided at the normal symbol start gate 12, the start port switch 72 provided at the normal electric accessory 13, and the first large prize provided at the first grand prize winning port 16. The winning opening switch 75, the second large winning opening switch 76 provided in the second winning opening 17, and the winning opening switch 77 provided in the normal winning openings 18 to 21 are used. When it is determined that the winning is made, the flag corresponding to each switch stored in the winning ball flag storage area 5202 of the RAM 52 is turned ON. At the start of the switch reading process, all the flags in the winning ball flag storage area 5202 are reset.

  When the switch reading process ends, a counter update process is then performed (S12). As described above, in this counter update process, each value of the random number acquisition counter stored in the counter storage area 5201 of the RAM 52 is added by a predetermined amount, and each value of the timer counter is subtracted by a predetermined amount.

  When the counter update process ends, a special electric accessory process is performed (S13). In this special electric accessory processing, processing for controlling the operation of the big hit gaming state for opening and closing the first grand prize winning port 16 and the second grand prize winning port 17 is performed. This control method has the characteristics of the present invention. . Details of this will be described later with reference to the flowchart shown in FIG.

  When the special electric accessory process is completed, a special symbol process is performed (S14). In this special symbol processing, determination of jackpot, determination of a special symbol displayed on the special symbol display unit 25, storage of a command for controlling fluctuation of the special symbol, jackpot gaming state indicating whether or not the jackpot gaming state Processing such as setting the flag to “ON” is performed. This special symbol process will be described later with reference to the flowcharts shown in FIGS.

  When the special symbol process is completed, a normal electric accessory process is performed (S15). In this ordinary electric accessory process, a process for controlling the operation of opening and closing the ordinary electric accessory 13 when a normal hit is made is performed, and details thereof will be described later with reference to a flowchart shown in FIG. .

  When the ordinary electric accessory processing is completed, ordinary symbol processing is performed (S16). In the normal symbol process, when the flag corresponding to the normal symbol operation switch 73 is “ON” in the switch reading process (S11), a normal random number is obtained and displayed on the display screen 28 as a normal hit determination. Such as determining the demo pattern variation pattern, storing commands for controlling the demo symbol and normal symbol variation, and setting the normal hit gaming state flag indicating whether or not the normal hit gaming state is “ON”, etc. Done. This normal symbol processing will be described later with reference to the flowcharts shown in FIGS.

  When the normal symbol process is completed, a payout process for paying out prize balls is performed (S17), and then an error check is performed (S18). If an error has occurred in the pachinko machine 1, an error is displayed on the display screen 28, the lighting device 35 is lit or blinked, or an error sound is generated from the speaker 48. Therefore, an error command for transmission to the sub-integrated board 58 in the command output process of S10 is stored in the command relation storage area 5207. Next, an information output process is performed (S19). In this information output process, various types of information such as jackpot information and starting information of the pachinko machine 1 are output via the output port 55 to a game hall management computer (not shown). When the information output process ends, the main process ends. When the interrupt signal is received from the interrupt signal generation circuit 57, the main process is executed again from the beginning.

  Here, the flow of the main process will be described by taking as an example the operation of the pachinko machine 1 when a certain game ball passes the normal symbol start gate 12 and is determined to be normal hit. When the player operates a launch handle 7 provided on the lower side of the game board 2 to launch a game ball into the game area 4, the game ball flows down the game area 4. When the game ball passes through the normal symbol start gate 12, passage of the game ball is detected in the switch reading process, and the corresponding flag in the winning ball flag storage area 5202 is set to “ON” (S11). Then, the normal symbol and the demo symbol in the display screen 28 are stopped, and the symbol indicating the normal hit is displayed. When the normal winning symbol stop display time elapses, the normal hit gaming state flag in the flag-related storage area 5208 is set to “ON” (S16). Thus, a command to release the ordinary electric accessory 13 is stored, and while the main process is repeatedly performed, a winning of five game balls to the ordinary electric accessory 13 is detected, or a predetermined release time ( When 4.5 seconds) elapses, a command for closing the ordinary electric accessory 13 is stored.

  Then, when the winning of the game ball to the ordinary electric accessory 13 is detected by the switch reading process (S11) and the corresponding flag is set to “ON”, a big hit determination is performed in the special symbol process (S14), and a special A process related to the variation of symbols is performed. In this jackpot determination, the probability of being determined as “big hit” is 2009/2011 or 2010/2011. If it is determined that the jackpot is won, the jackpot gaming state flag in the flag related storage area 5208 is set to “ON”, so that in the next special electric accessory process (S13) of the main process to be performed, the two big winning holes 16 , 17 are stored. When the jackpot is a “probability change jackpot”, both the probability fluctuation flag and the short-time state flag are set to “ON” after the jackpot gaming state ends. If the next normal hit determination is performed when the short-time state flag is “ON”, the normal hit is again made with a probability of 718/719 (S16), and therefore, when the short-time state flag is “OFF” (normal win) It is expected that the next ordinary electric accessory 13 will be opened (S15) and an opportunity for a jackpot determination to be made (S14) at a time interval shorter than the probability 5/719). In other words, when the time-short state flag is “ON”, a normal hit and a big win are continuously generated at shorter time intervals than when it is “OFF”, and a large number of game balls are paid out to the player.

  Next, details of the normal symbol processing (S16) of the main processing will be described with reference to FIGS. First, flags used in normal symbol processing will be described. The flag relation storage area 5208 stores a normal symbol display state flag, a normal winning game state flag, a short time game state flag, and the like. The normal symbol display state flag is a flag indicating the state of the normal symbol display unit 24, and is “1” when the normal symbol display unit 24 is changing (during change), and when stopped (during stop display). ) Is stored as “2”, and “0” is stored when neither change nor stop display is displayed. The normal hit game state flag is “1” stored in the normal hit game state and is “ON”; otherwise, “0” is stored and “OFF”. ing. Also, the time-saving gaming state flag stores “1” when the time-saving gaming state is set and is “ON”, and otherwise stores “0” and is “OFF”. . The short-time gaming state is a gaming state in which the variation time of the normal symbol is shorter than that in the non-short-time gaming state and the probability of being determined as “ordinary winning” in the normal hit determination is higher than that in the non-short-time gaming state. . The initial value of each flag is “0”.

  As shown in FIG. 9, when the normal symbol process of the main process is started, a process related to the passing of the game ball to the normal symbol start gate 12 is performed. First, it is determined whether or not the game ball has passed through the normal symbol start gate 12 (S21). In the main process switch reading process (S11, see FIG. 8), when the normal symbol operation switch 73 provided in the normal symbol start gate 12 detects the passing of the game ball, the normal winning flag flag storage area 5202 The flag corresponding to the symbol operation switch 73 is “ON”. Therefore, in S21, it is determined whether or not the flag corresponding to the normal symbol operation switch 73 is “ON”. If the flag is not “ON” (S21: NO), the game ball is the normal symbol start gate 12. Since it has not passed, it transfers to determination of S25 as it is.

  When the flag corresponding to the normal symbol operation switch 73 is “ON” (S21: YES), since the game ball passes through the normal symbol start gate 12, a random number for the game ball is acquired and the normal symbol is acquired. It is stored in the hit relation information storage area 5203. However, the number of normal symbol actuated holding balls that can acquire and store random numbers is four. Therefore, it is determined whether or not the value of the normal symbol operation reserved ball number storage area 5204 is “4” (S22). If the value of the normal symbol operation reserved ball number storage area 5204 is “4” (S22: YES), since the random number for this game ball cannot be stored, the process proceeds to S25 as it is.

  When the value of the normal symbol operation reserved ball number storage area 5204 is not “4”, that is, between “0” and “3” (S22: NO), “1” is added to the value (S23). Then, a random number is stored in the storage area of the number corresponding to the value of the normal symbol operation reserved ball number storage area 5204 in the normal hit relation information storage area 5203 (see FIG. 6) (S24). Specifically, the value of the ordinary hit determination counter is stored in the ordinary hit random number column, and the value of the variation pattern determination counter is stored in the variation pattern determination random number column.

  Next, a determination is made as to whether or not the normal hit gaming state is based on the normal hit gaming state flag (S25). In the normal hit gaming state, the normal hit determination and the determination result notification are not performed. Therefore, when the normal hit game state flag is “ON” and the normal hit game state is set (S25: YES), the process returns to the main process without doing anything.

  When the normal hit game state flag is not “ON” (S25: NO), the normal symbol display unit 24 is controlled because it is not the normal hit game state. First, it is determined whether or not the normal symbol display unit 24 is changing based on the normal symbol display state flag (S26). If the normal symbol display state flag is not “1” and is not changing (S26: NO), it is determined whether or not the normal symbol display state flag is being stopped (S27). When the normal symbol display state flag is not “2” and the stop display is not being performed (S27: NO), the normal hit determination is performed.

  Therefore, as shown in the flowchart of FIG. 10, it is confirmed whether or not there is a game ball to be subjected to the normal hit determination (S28). If the value of the normal symbol operation reserved ball number storage area 5204 is not “1” or more (S28: NO), there is no game ball to be subjected to the normal hit determination, and the process directly returns to the main process. If it is “1” or more (S28: YES), there is a game ball to be determined for normal hit, so “1” is subtracted from the value of the normal symbol operation reserved ball number storage area 5204 (S29), and the normal hit relationship The value stored in the information storage area 5203 is shifted. That is, the random number stored in the first storage area is shifted to the determination area, the random number stored in the second to fourth storage areas is shifted to the storage area one number lower, and the value in the fourth storage area Is cleared. (S30).

  Next, a normal hit determination is performed. The normal hit determination is performed using a value stored in the normal hit random number column of the determination area depending on whether or not the gaming state is the short-time gaming state. Note that the time-short game state flag indicating whether or not the time-short game state is set is switched between “ON” and “OFF” in the special electric accessory process and the special symbol process described later. In the case of the short game state when “1” is stored in the short time state flag and is “ON” (S31: YES), the number of specific values determined as the normal win is more than in the case of the non-short time game state. The normal hit determination table (not shown) with many high probabilities is referenced to determine the normal hit determination (S32).

  Next, when it is determined as “ordinary hit” (S33: YES), a variation pattern determination process is performed when it is determined as normal hit during the short-time gaming state (S34). Specifically, first, a variation pattern determination table stored in the determination area of the normal hit relation information storage area 5203 is referred to by referring to a variation pattern determination table (not shown) for the normal hit in the short-time gaming state. Is determined. Then, a variation pattern designation command indicating the determined variation pattern is stored in the command relation storage area 5207. This variation pattern designation command is transmitted to the sub-integrated board 58 and the relay board 47 in the command output process (S10, see FIG. 8), designates the decided fluctuation pattern, and displays the demo symbol display section D1 in the display screen 28. ~ D3 and normal symbol display unit 24 start to change. In addition, when it is not determined as “normal hit” in the normal hit determination (S33: NO), the change pattern is determined with reference to the change pattern determination table when the normal hit determination in the short-time gaming state is out of place. Then, a variation pattern designation command indicating the determined variation pattern is stored in the command relation storage area 5207 (S35).

  On the other hand, in the non-short-time game state in which “0” is stored in the short-time game state flag and is “OFF” (S31: NO), the specific value determined as the normal win is the short-time game. The normal hit determination table with a lower probability than that in the state is referred to, and the normal hit determination is performed (S36). Next, when it is determined that “normal hit” (S37: YES), the fluctuation pattern is determined with reference to the fluctuation pattern determination table for normal hit in the non-time-saving gaming state, and the fluctuation indicating the determined fluctuation pattern is determined. The pattern designation command is stored in the command relation storage area 5207. (S38). If it is not determined to be “ordinary hit” (S37: NO), the change pattern is determined by referring to the change pattern determination table when the normal hit determination in the non-time-saving gaming state is out of place. The changed pattern designation command is stored (S39).

  Next, the variation time of the normal symbol determined by the determined variation pattern is stored in the normal symbol variation time counter TC1 (S40). This variation time is preset for each variation pattern. In the present embodiment, all the variation patterns in the short-time gaming state are set to a variation time of 2 seconds, whereas in the non-short-time gaming state, a plurality of variation times are assigned to each variation pattern. The setting of the fluctuation time can be changed as appropriate. Then, “1” indicating that the normal symbol display unit 24 is changing is stored in the normal symbol display state flag (S41), the normal symbol process is terminated, and the process returns to the main process.

  Further, in the determination of S26 shown in the flowchart of FIG. 9, when “1” is stored in the normal symbol display state flag and it is determined that the normal symbol display unit 24 is changing (S26: YES). Then, it is determined whether or not the variation time has elapsed (S47). This determination is normally made based on the value of the symbol variation time counter TC1. When the value of the normal symbol variation time counter TC1 set in S40 (see FIG. 10) becomes “0”, the variation time of the ordinary symbol has elapsed (S47: YES), so the command relation storage area 5207 A normal symbol stop command is stored (S48). This normal symbol stop command is transmitted to the sub-integrated board 58 and the relay board 47 in the command output process (S10, see FIG. 8), and the demonstration symbol display units D1 to D3 and the normal symbol display unit 24 in the display screen 28 are stopped. Instruct. Then, the predetermined stop display time (0.8 seconds in the present embodiment) is stored in the normal symbol stop time counter TC2 (S49), and “2” indicating that the normal symbol display unit 24 is displaying the stop is displayed. It is stored in the normal symbol display state flag (S50). Then, the normal symbol process is terminated and the process returns to the main process. On the other hand, if it is determined in S47 that the value of the normal symbol variation time counter TC1 is not “0” and the variation time has not yet elapsed (S47: NO), the variation of the normal symbol display unit 24 is continued. . Therefore, the process returns to the main process as it is.

  In the determination of S27, “2” is stored in the normal symbol display state flag, and when it is determined that the normal symbol display unit 24 is in a stop display (S27: YES), the stop display time is set. A determination is made as to whether or not the time has elapsed (S51). This determination is normally made based on the value of the symbol stop time counter TC2. If the value of the normal symbol stop time counter TC2 set in S49 is subtracted to “0” in the counter update process (S12, see FIG. 8), the stop display time has elapsed (S51: YES) ), “0” indicating that the normal symbol display unit 24 is neither stopped display nor fluctuating is stored in the normal symbol display state flag (S52).

  If the normal winning random number is a random number determined in advance as “normal winning” (S53: YES), “1” is stored in the normal winning game state flag stored in the flag relation storage area 5208 of the RAM 52. In step S54, the normal symbol process is terminated and the process returns to the main process. This normal winning game state flag is used when it is determined whether or not to perform a process for opening and closing the ordinary electric accessory 13 in an ordinary electric accessory process (see FIG. 11) described later. On the other hand, if it is not normal (S53: NO), the normal symbol process is terminated as it is, and the process returns to the main process. If it is determined in S51 that the value of the normal symbol stop time counter TC2 is not “0” and the stop display time has not yet elapsed (S51: NO), the normal symbol display unit 24 displays Will continue to display symbols. Therefore, the process returns to the main process as it is.

  As described above, when the game ball passes through the normal symbol start gate 12 (S21: YES), a random number is acquired (S24), and a normal hit determination is performed according to whether or not the game is in the short-time game state ( S32, S36), the variation pattern is determined, and the variation pattern designation command is stored (S34, S35, S38, S39). Then, while the main process is repeatedly performed, the normal symbol process is also repeatedly performed. When the fluctuation time has elapsed (S26: YES, S47: YES), the normal symbol stop command is stored (S48). Furthermore, when the normal symbol processing is repeatedly executed and the stop display time has elapsed (S27: YES, S51: YES), the notification of the determination result of the normal hit determination is terminated, and when it is normal hit (S53: YES) In order to shift to the normal winning gaming state, the normal winning gaming state flag is set to “ON” (S54), and the process returns to the main process.

  Next, details of the normal electric accessory process (S15) of the main process will be described with reference to FIG. First, the flag used in the ordinary electric accessory processing will be described. As main flags used here, there are a normal electric accessory opening flag and a normal symbol variation waiting flag. The normal electric accessory opening flag is a flag indicating whether or not the normal electric accessory 13 is open. During the opening of the normal electric accessory 13, “1” is stored and becomes “ON” and closed. “0” is stored therein and “OFF” is set. The normal symbol fluctuation waiting flag is a flag that indicates whether or not the normal electric accessory 13 is waiting until the next normal symbol can be changed after the normal electric accessory 13 is closed. “1” is stored and “ON” is stored, and “0” is stored and “OFF” is stored unless the variation is on standby. The initial values are both “0”.

  As shown in FIG. 11, when the ordinary electric accessory process of the main process is started, a determination is made as to whether or not the normal hit gaming state is made based on the normal hit gaming state flag (S61). When it is not in the normal hit gaming state, the normal electric accessory 13 is not opened / closed. Therefore, when the normal hit game state flag is “OFF” and the normal hit game state is not set (S61: NO), the process directly returns to the main process.

  On the other hand, when the normal hit gaming state flag is “ON” and the normal winning gaming state is set (S61: YES), processing related to opening / closing the normal electric accessory 13 is performed. First, a determination is made as to whether or not the normal symbol variation waiting flag is awaiting, based on the normal symbol variation waiting flag (S62). When the normal symbol variation waiting flag is “OFF” and the variation waiting is not performed (S62: NO), it is determined whether or not the ordinary electric accessory 13 is being opened by the ordinary electric accessory releasing flag. Performed (S63). If the normal electric combination opening flag is “OFF” and the normal electric combination 13 has not been opened yet (S63: NO), the normal electric combination release command for opening the normal electric combination 13 is stored in the RAM 52. Is stored in the command relation storage area 5207 (S64). Then, the maximum opening time (4.5 seconds) of the ordinary electric accessory 13 is stored in the ordinary electric accessory opening time counter TC3 (S65), and “1” indicating that the ordinary electric accessory 13 is being opened is displayed. It is stored in the normal electric accessory opening flag and is set to “ON” (S66).

  Next, it is determined whether or not the value of the ordinary electric accessory winning ball counter is 5 (S67). Each time a game ball wins the ordinary electric accessory 13, “1” is added to the value of the ordinary electric accessory winning ball counter in the switch reading process of the main process (see FIG. 8). If the value of the normal electric accessory winning ball counter is less than 5, that is, “0” to “4” (S67: NO), the normal electric accessory opening time counter TC3 set in the process of S65 It is determined whether the maximum opening time of the electric accessory 13 has elapsed (S68). If the maximum open time of 4.5 seconds has not elapsed (S68: NO), the process returns to the main process.

  Then, in the normal electric accessory process of the main process performed after that, the normal hit gaming state (S61: YES), the normal symbol fluctuation waiting is not made (S62: NO), and the normal electric accessory 13 is open. (S63: YES), these determinations are repeated until the number of winning balls reaches “5” or until the maximum opening time of the ordinary electric accessory 13 has elapsed (S67: NO, S68). : NO). When the number of winning balls is “5” (S67: YES), or when the opening time of 4.5 seconds has elapsed (S68: YES), a process of closing the ordinary electric accessory 13 is performed. Is called. Therefore, the ordinary electric accessory closing command for closing the ordinary electric accessory 13 is stored in the command relation storage area 5207 (S69). Next, the standby time (23.2 seconds) until the next normal symbol can be changed is stored in the normal symbol change standby time counter TC4 (S70), and the value of the normal electric accessory winning ball counter is the initial value. Is initialized to "0" (S71). Next, “0” is stored in the flag indicating that the normal electric accessory is being released in the flag-related storage area 5208 and is set to “OFF” (S72), and “1” indicating that the normal symbol is on standby is changed. It is stored in the waiting flag and is set to “ON” (S73). Then, the process returns to the main process.

  If the normal symbol variation standby flag is “ON” and the normal symbol variation standby is in progress (S62: YES), whether or not the standby time has elapsed is determined by the value of the normal symbol variation standby time counter TC4. Is determined (S74). When it is determined that the value of the normal symbol variation standby time counter TC4 is not “0” and the standby time is being measured (S74: NO), the process returns to the main process. If the time elapses while the main process is repeatedly performed, and the value of the normal symbol variation waiting time counter TC4 is “0” and it is determined that the waiting time has elapsed (S74: YES), the flag “0” is stored in the normal hit gaming state flag in the relation storage area 5208 and set to “OFF” (S75), and the normal symbol variation waiting flag is set to “OFF” indicating that the variation waiting flag is not waiting (S76). Then, the ordinary electric accessory processing is terminated and the processing returns to the main processing.

  As described above, when the determination result of the normal hit determination is “normal hit” and the normal hit gaming state is reached (S61: YES), the normal electric accessory 13 is released (S64). When the winning of five game balls is detected (S67: YES) or when the maximum opening time of 4.5 seconds has elapsed (S68: YES), the ordinary electric accessory 13 is closed (S69). However, the normal hit gaming state flag is continuously “ON” until the standby time of 23.2 seconds measured from that time elapses (S74: NO), and “OFF” when the standby time elapses. (S74: YES, S75). As described above, since the normal hit determination is not performed when the normal hit game state flag is “OFF”, a random number is stored in the first storage area of the normal hit relation information storage area 5203 (see FIG. 6). Even if is stored, the normal hit determination is not performed for 23.2 seconds after the ordinary electric accessory 13 is closed. And, the length of the waiting time of 23.2 seconds is that all of the special symbol changes / stops and jackpot games, which will be described later, are performed up to 5 times per ordinary hit, taking the longest time. It is set to a length that continues until the end time. Therefore, the normal hit determination is not performed during the change of the special symbol or the big hit game. Details of this will be described later with reference to FIG.

  Next, details of the special symbol process (S14) of the main process will be described with reference to FIGS. The flags used for the special symbol include a special symbol display state flag, a jackpot gaming state flag, a probability variation flag, and the like. The special symbol display state flag is a flag indicating the state of the special symbol display unit 25. When the special symbol display unit 25 is changing, “1” is displayed. Stores “0”. The jackpot gaming status flag is “1” stored and “ON” when the jackpot gaming state is set, and “0” is stored and “OFF” otherwise. . Further, the probability variation flag stores “1” and “ON” when the probability variation state is set, and stores “0” and “OFF” otherwise. Note that the probability variation state is a gaming state that has a higher probability of being determined to be a “big hit” than the non-probability variation state. The initial value of each flag is “0”.

  As shown in FIG. 12, when the special symbol process of the main process is started, a process related to winning a game ball 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 (S81). Among the flags stored in the winning ball flag storage area 5202, when the flag corresponding to the start port switch 72 provided in the ordinary electric accessory 13 is “OFF” (S81: NO), Since the game ball has not won the ordinary electric accessory 13, the process proceeds to the determination of S85 as it is.

  When the flag corresponding to the start port switch 72 is “ON” (S81: YES), the game ball is won to the ordinary electric accessory 13, and therefore the value of the special symbol operation reserved ball number storage area 5206 is It is determined whether or not “4” (S82). If it is “4” (S82: YES), since the random number for this game ball cannot be stored, the process proceeds to S85 as it is.

  When the value of the special symbol operation reserved ball number storage area 5206 is not “4”, that is, any of “0” to “3” (S82: NO), the special symbol operation reserved ball number storage area 5206 “1” is added to the value (S83). Then, a random number is stored in the storage area of the number corresponding to the value of the special symbol operation reserved ball number storage area 5206 in the jackpot relation information storage area 5205 (see FIG. 7) (S84). Specifically, the value of the jackpot determination counter is in the jackpot random number field, the value of the hit special symbol creation counter is in the bonus special symbol determination random number field, and the value of the special bonus symbol creation counter is in the outlier special symbol determination random number column. Each is remembered.

  Next, based on the jackpot gaming state flag, it is determined whether or not the jackpot gaming state is set (S85). When it is a jackpot gaming state, jackpot determination and notification of the determination result are not performed. Therefore, if the jackpot gaming state flag is “ON” and the jackpot gaming state is set (S85: YES), the process returns to the main process without doing anything.

  If the jackpot game state flag is not “ON” (S85: NO), the game is not in the jackpot game state, and therefore processing related to the control of the special symbol display unit 25 is performed. First, it is determined whether or not the special symbol display unit 25 is changing based on the special symbol display state flag (S86). If the special symbol display state flag is not “1” and is not changing (S86: NO), it is determined whether or not the special symbol display state flag is being stopped (S87). When the special symbol display state flag is not “2” and stop display is not being performed (S87: NO), a big hit determination is performed.

  Therefore, as shown in the flowchart of FIG. 13, it is confirmed whether or not there is a game ball for which a jackpot determination is to be made (S88). If the value in the special symbol operation reserved ball number storage area 5206 is not equal to or greater than “1” (S88: NO), there is no game ball to be subjected to the jackpot determination, and the process directly returns to the main process. If it is equal to or greater than “1” (S88: YES), there is a game ball for which a jackpot determination is to be made, so the value in the special symbol actuated holding ball number storage area 5206 is subtracted from “1” (S89), and the jackpot relation information is stored. The value stored in area 5205 is shifted. That is, the random number stored in the first storage area is shifted to the determination area, the random number stored in the second to fourth storage areas is shifted to the storage area one number lower, and the value of the fourth storage area Is cleared (S90).

  Next, a jackpot determination is performed. The jackpot determination is performed using a value stored in the jackpot random number column of the determination area depending on whether or not the gaming state is a probability variation state. In the case of the probability variation state in which “1” is stored in the probability variation flag and is “ON” (S91: YES), the number of specific values determined as jackpots is more than in the case of the non-probability variation state. The jackpot determination is performed with reference to many high probability jackpot determination tables (not shown) (S92). On the other hand, in the case of the non-probability variation state in which the probability variation flag is “OFF” (S91: NO), the low probability that the number of specific values determined as the jackpot is smaller than the high probability jackpot determination table. The jackpot determination table is referred to to determine the jackpot determination (S93).

  Next, when it is determined as “big hit” (S94: YES), in the hit special symbol determination process (S95), a plurality of hits are determined based on the value stored in the hit special symbol determination random number column of the determination area. One of the special symbols is determined, and a special symbol designating command indicating the determined special symbol is stored in the command relation storage area 5207. On the other hand, when it is determined as “missing” (S94: NO), one of the extra special symbols is determined based on the value stored in the extra special symbol determining random number column in the special extra symbol determining process (S96). A special symbol designating command indicating the determined special symbol is stored.

  Next, it is determined whether or not the value of the special symbol operation reserved ball number storage area 5206 is “0” (S97). If it is “0” (S97: YES), the first of the special symbol is stored. The variation time (0.4 seconds) is stored in the special symbol first variation time counter TC5 (S98). Further, when there is a holding ball and the value of the special symbol operation holding ball number storage area 5206 is not “0” (S97: NO), the second variation time (1.8 seconds) of the special symbol is the special symbol number. It is stored in the two variation time counter TC6 (S99).

  Next, a special symbol variation start command for starting the variation of the special symbol display unit 25 is stored in the command relation storage area 5207 (S100). Then, “1” indicating that the special symbol display unit 25 is changing is stored in the special symbol display state flag (S101), and the process returns to the main process.

  In the determination of S86 shown in the flowchart of FIG. 12, when the special symbol display state flag stores “1” and it is determined that the special symbol display unit 25 is changing (S86: YES). Whether or not the variation time has passed is determined based on whether or not the value of the special symbol variation time counter set in S98 or S99 (see FIG. 13) is “0” (S106). When the value of the special symbol variation time counter is “0”, since the variation time of the special symbol has elapsed (S106: YES), a special symbol stop command for stopping the variation of the special symbol display unit 25 is stored. (S107). Then, the 0.5 second stop display time is stored in the special symbol stop time counter TC7 (S108), and "2" indicating that the special symbol display unit 25 is in the stop display is stored in the special symbol display state flag. (S109), the process returns to the main process. On the other hand, if it is determined in S106 that the value of the special symbol variation time counter is not “0” and the variation time has not yet elapsed (S106: NO), the variation of the special symbol display unit 25 is continued. Therefore, the process returns to the main process as it is.

  If it is determined in S87 that “2” is stored in the special symbol display state flag and the special symbol display unit 25 is stopped (S87: YES), it is set in S108. Whether or not the stop display time has elapsed is determined based on the value of the special symbol stop time counter TC7 (S110). When the value of the special symbol stop time counter TC7 is “0”, since the stop display time has elapsed (S110: YES), “0” indicating that the special symbol display unit 25 is not in a stop display or in a change state is displayed. It is stored in the special symbol display state flag (S111). Then, when the probability variation flag and the short time state flag in the flag relation storage area 5208 are “ON”, a process of switching to “OFF” is performed (S112).

  If the jackpot random number is a random number determined in advance as “big hit” (S113: YES), “1” is stored in the jackpot gaming state flag in the flag relation storage area 5208 and turned “ON” (S114). ), The special symbol process is terminated and the process returns to the main process. This jackpot game state flag is used when determining whether or not to perform a process of opening and closing the first big prize opening 16 and the second big prize opening 17 in the special electric accessory process (see FIG. 14) described later. The If it is not a big hit (S113: NO), the special symbol process is terminated as it is, and the process returns to the main process. If it is determined in S110 that the value of the special symbol stop time counter TC7 is not "0" and the stop display time has not yet elapsed (S110: NO), the special symbol display unit 25 displays Will continue to display symbols. Therefore, the process returns to the main process as it is.

  As described above, when the game ball wins the ordinary electric accessory 13 (S81: YES), a random number is acquired (S84), and a jackpot determination is performed according to whether or not the probability variation state is present (S92). , S93), the special symbol display unit 25 starts to change (S100). When the fluctuation time elapses while the main process is repeatedly executed (S86: YES, S106: YES), a process for stopping the fluctuation of the special symbol is performed (S107). When the time further elapses and the stop display time ends (S87: YES, S110: YES), the notification of the determination result of the jackpot determination is terminated, and when the jackpot is determined (S113: YES), the jackpot gaming state flag Is set to “ON” (S114), and the process returns to the main process.

  Next, details of the special electric accessory process (S13) of the main process, which is the main part of the present invention, will be described with reference to FIG. In the present embodiment, the first big prize opening 16 and the second big prize opening 17 are arranged side by side in the up and down direction. After opening 16, the upper second big prize opening 17 is opened. In the special electric accessory process, a process for opening and closing the two large winning openings 16, 17 is performed.

  First, the flag used in the special electric accessory processing will be described. The main flags used here include a big prize opening open flag, a big prize opening waiting flag, and a first big prize opening / closing end flag, which are stored in the flag relation storage area 5208 of the RAM 52. The big prize opening open flag is a flag indicating whether one of the first big prize opening 16 and the second big prize opening 17 is opened, and when either one of the big prize opening is opened. “1” is stored and becomes “ON”, and when both are closed, “0” is stored and becomes “OFF”. In addition, the waiting flag for waiting for the special prize opening process is 0.4 seconds from when the first big prize opening 16 or the second big prize opening 17 is closed until the next processing relating to the special prize winning openings 16 and 17 is performed. It is a flag indicating whether or not it is in the standby time. During the standby time, “1” is stored and becomes “ON”, and when it is not during the standby time, “0” is stored and becomes “OFF”. The first big prize opening / closing end flag is a flag indicating whether or not the opening / closing operation of the first big prize opening 16 that has been performed first during the jackpot gaming state has ended. When the operation is finished, “1” is stored and turned “ON”, and when not finished, “0” is stored and turned “OFF”. The initial values are all “0”.

  As shown in FIG. 14, when the special electric accessory process of the main process is started, it is determined by the jackpot gaming state flag whether or not the jackpot gaming state is set (S121). When it is not in the jackpot game state, the two big winning openings 16, 17 are not opened / closed. Therefore, when the jackpot gaming state flag is “OFF” and the jackpot gaming state is not set (S121: NO), the process directly returns to the main process.

  On the other hand, when the jackpot gaming state flag is “ON” and the jackpot gaming state is set (S121: YES), the processing related to the two jackpots 16 and 17 is performed. First, it is determined whether or not it is during the waiting time until the next process related to the big winning openings 16 and 17 is performed by the big winning opening process waiting flag (S122). When the big prize opening waiting flag is “OFF” and not in the waiting time (S122: NO), whether or not one of the two big prize openings 16, 17 is opened by the big prize opening open flag. Is determined (S123). When the big prize opening open flag is “OFF” and the big prize winning openings 16 and 17 are both closed (S123: NO), a process of opening one of the two big prize winning openings 16 and 17 is performed. Done.

  Therefore, it is determined whether or not the opening / closing operation of the first big prize opening 16 which is performed prior to the opening / closing operation of the second big prize opening 17 is ended by the first big prize opening / closing end flag (S124). ). When the opening / closing end flag of the first grand prize opening is “OFF” and the opening / closing operation of the first big prize opening 16 has not been finished yet (S124: NO), the first big prize opening 16 is opened. The first big prize opening release command is stored in the command relation storage area 5207 (S125). This command is output to the relay board 47 in the command output process (S10, see FIG. 8) of the main process to be performed next. Then, the maximum opening time (1.5 seconds) of the special winning openings 16, 17 is stored in the special winning opening opening counter TC8 (S127), indicating that one of the special winning openings 16, 17 is open. “1” is stored in the big prize opening open flag and is set to “ON” (S128).

  Next, it is determined whether or not a game ball has won the first grand prize opening 16 (S129). In the winning ball flag storage area 5202, the flag corresponding to the first big winning hole switch 75 provided at the big winning hole 16 is “OFF”, and the game ball has won the first big winning hole 16. If it is determined that there is not (S129: NO), it is determined whether or not the maximum opening time of the first big winning opening 16 has passed by the big winning opening opening time counter TC8 set in the process of S127. (S130). If the maximum opening time of 1.5 seconds has not elapsed (S130: NO), the process returns to the main process.

  Then, in the special electric accessory processing of the main processing performed after that, it is a big hit gaming state (S121: YES), and it is not during the waiting time until the next processing related to the big prize winning openings 16, 17 is performed (S122: NO) When one of the two big winning openings 16, 17 is open (S123: YES), the game ball wins the first big winning opening 16 or the maximum of the first big winning opening 16 These determinations are repeatedly performed until the opening time elapses (S129: NO, S130: NO). Then, when the game ball wins the first grand prize opening 16 (S129: YES) or when the maximum opening time of 1.5 seconds has elapsed (S130: YES), the first big prize opening 16 is closed. Processing is performed. Therefore, a big winning port closing command for closing the opened first big winning port 16 or the second big winning port 17 is stored in the command related storage area 5207 (S131). This command is transmitted to the relay board 47 in the next command output process (S10, see FIG. 8).

  Next, a waiting time (0.4 seconds) until the next processing relating to the winning prize openings 16 and 17 is performed is stored in the winning prize opening waiting time counter TC9 (S132), and the winning prize opening in the flag-related storage area 5208 is stored. “0” is stored in the open flag and is set to “OFF” (S133). Then, “1” indicating that it is during the waiting time until the next processing relating to the big winning openings 16, 17 is stored in the big winning opening process waiting flag and is set to “ON” (S134). Return to processing.

  Further, when the special winning a prize opening process waiting flag is “ON” (S122: YES), it is determined whether or not the waiting time has elapsed based on the value of the special prize opening process waiting time counter TC9 ( S136). If it is determined that the value of the big prize opening process waiting time counter TC9 is not “0” and the waiting time is being measured (S136: NO), the process directly returns to the main process. Then, when time passes while the main process is repeatedly performed, and the value of the big prize opening waiting time counter TC9 becomes “0” and it is determined that the waiting time has passed (S136: YES). Then, “0” indicating that it is not during the waiting time is stored in the big prize waiting flag and is set to “OFF” (S137).

  Next, it is determined whether or not the first big prize opening / closing end flag indicating that the opening / closing operation of the first big prize opening 16 has been completed is “ON”. If the first big prize opening / closing end flag is “OFF” (S138: NO), this flag is switched to “ON” (S139), and the process returns to the main process.

  Then, in the next special electric accessory processing to be performed, it is a jackpot gaming state (S121: YES), not during the waiting time until the next processing related to the big winning opening 16, 17 (S122: NO), Since the two big winning openings 16, 17 are both closed (S123: NO), a process of opening either of the two big winning openings 16, 17 is performed. Here, in the process of S139 of the special electric accessory process performed earlier, the big winning opening opening / closing end flag indicating that the opening / closing operation of the first big winning opening 16 has ended is set to “ON”. Therefore (S124: YES), the second big prize opening opening command for opening the second big prize opening 17 is stored in the command relation storage area 5207 (S126). Next, as in the case where the first big prize opening 16 is opened, the maximum opening time of 1.5 seconds is stored in the big prize opening time counter TC8 (S127), and the big prize opening open flag is “ON”. (S128). Then, while the main process is repeatedly performed, whether the winning ball flag corresponding to the second big prize opening switch 76 provided in the second big prize opening 17 is “ON” (S129: YES), or When the maximum opening time of 5 seconds has elapsed (S130: YES), a winning prize closing command is stored (S131), and a waiting time of 0.4 seconds is stored in the winning prize processing waiting time counter TC9. (S133). Next, the big prize opening open flag is set to “OFF” (S133), and the big prize opening waiting flag is set to “ON” (S134).

  Then, in the special electric accessory process that is repeatedly performed thereafter, when the waiting time of 0.4 seconds set in S133 has elapsed (S121: YES, S122: YES, S136: YES), the special winning opening process waiting flag is set. Is set to “OFF” (S137). Next, when the first big prize opening / closing end flag is “ON” (S138: YES), the first big prize opening / closing end flag is set to “OFF” (S140), and the two big prize winning openings. Since both the opening and closing operations 16 and 17 have been completed, “0” is stored in the jackpot gaming state flag and is set to “OFF” (S141).

  Next, a flag process relating to the gaming state is performed. In the process of S95 (see FIG. 13) in the special symbol process described above, the special symbol is determined. If this special symbol is a probability variation symbol (S142: YES), “1” indicating the probability variation state is stored in the probability variation flag and is set to “ON” (S143). “1” indicating the presence is stored in the time reduction state flag and is set to “ON” (S144), and the process returns to the main process. On the other hand, if the determined special symbol is a non-stochastic variation symbol (S142: NO), the special electric accessory process is terminated as it is, and the process returns to the main process.

  As described above, when the determination result of the jackpot determination is “big hit” and the jackpot gaming state is reached (S121: YES), the first of the two winning winning openings 16, 17 is provided below. The big winning opening 16 is opened first (S124: NO, S125). When the game ball wins the first grand prize opening 16 (S129: YES) or when the maximum opening time of 1.5 seconds elapses (S130: YES), the first big prize opening 16 is closed ( S131). Next, after the waiting time of 0.4 seconds elapses, the second big prize opening 17 provided above is opened (S124: YES, S126), and the second big prize opening 17 is closed again after 0.4 seconds. After the waiting time is measured, the jackpot gaming state flag is set to “OFF” (S141). If the probability variation is a big hit (S142: YES), both the probability variation flag and the short time state flag are set to "ON" (S143, S144).

  Next, a game in the pachinko machine 1 of the present embodiment will be described with reference to the timing chart of FIG. FIG. 15 is a timing chart showing each control in the pachinko machine 1 corresponding to the passage of time. In FIG. 15, as each control of the pachinko machine 1, the normal symbol operation SW (normal symbol operation switch 73), the normal symbol (normal symbol display unit 24), the normal electric accessory 13, the start port SW (start port switch 72). ), A special symbol (special symbol display unit 25), a special winning opening (first large winning port 16 and second large winning port 17), a probability variation state, and a short-time gaming state. Further, in FIG. 15, in the normal hit determination due to the first game ball that has passed through the normal symbol start gate 12, it is determined as “normal win”, and all five consecutive big hit determinations performed thereafter are “probability”. The control is exemplified when it is determined that “variable big hit” and “normal hit” regarding the second game ball are also “normal hit”.

  First, when it is detected by the normal symbol operation switch that the game ball has passed the normal symbol start gate 12 (S21), the probability variation and the short time are in the “stop” state, that is, the non-short time game state. Therefore, the normal hit determination with a low probability regarding the game ball is performed (S36). Then, the normal symbol starts to change (S38). Here, the variation time of the normal symbol during the non-time-saving gaming state varies depending on the determined variation pattern (S40). In addition, the probability of determining “normal hit” in the normal hit determination with low probability is 5/719. In addition, although three game balls have passed through the normal symbol start gate, other than the first one is a normal symbol operation holding ball.

  Next, when the variation time of the normal symbol specified by the determined variation pattern elapses (S47: YES), the normal symbol is stopped (S48), and after the stop display time of 0.8 seconds, the normal winning gaming state is obtained. (S54). In the normal winning gaming state, first, the ordinary electric accessory 13 is released (S64), and a game ball can be won. Then, when the maximum opening time of 4.5 seconds elapses or a winning of five game balls is detected, the opened ordinary electric accessory 13 is closed (S69). In the timing chart shown in FIG. 15, the ordinary electric accessory 13 is closed by detecting the winning of five game balls. The normal hit gaming state continues until the normal symbol variation waiting time of 23.2 seconds elapses after the normal electric accessory is closed, and no new normal hit determination is made during the normal hit gaming state.

  Next, when the winning of the first game ball to the ordinary electric accessory 13 is detected by the start port switch 72 (S81), since the probability variation is in the “stop” state, the low value related to the game ball is low. A jackpot determination with probability (2009/2011) is made (S93), and the special symbol starts to change (S100). Here, when the winning of the first game ball is detected, the number of special symbol operation holding balls is “0” (S97: YES), so the variation time of the special symbol is set to 0.4 seconds. (S98). When the variation time of 0.4 seconds elapses, the special symbol stops (S107), and when the stop display time of 0.5 seconds elapses, a big hit gaming state is entered. When it is determined that the jackpot is a jackpot, the probability that the jackpot is a “probability variation jackpot” is 81/84.

  In the big hit gaming state, first, the first big winning opening 16 provided below the two big winning openings 16, 17 is opened for a maximum of 1.5 seconds (S124: NO, S125). The grand prize winning holes 16 and 17 are closed when the maximum opening time of 1.5 seconds elapses or at least one game ball winning is detected (S131). After the processing waiting time of 4 seconds, the second big prize opening 17 is opened for a maximum of 1.5 seconds (S124: YES, S126). Then, after closing the second grand prize winning port 17, a series of big hit games are completed after a processing waiting time of 0.4 seconds again (S141).

  Next, when the first jackpot game is over, the probability variation is in the “actuated” state, so the jackpot at the high probability (2010/2011) regarding the second game ball that won the ordinary electric accessory 13 A determination is made (S92), and the special symbol starts to change (S100). At this time, since the special symbol operation holding ball is “1” or more (S97: NO), the variation time of the special symbol is set to 1.8 seconds (S99). And since the determination result of the jackpot determination is “jackpot”, the same processing as the first jackpot game described above is performed. Thereafter, similar to the first and second special symbol variations, the third to fifth special symbol variations are controlled, and the jackpot game is played after the special symbol is stopped. In this embodiment, when the determination result by jackpot determination is “probability variation jackpot”, the probability variation state and the short-time gaming state start operation at the end of the jackpot game, and stop after the next special symbol changes These game states are set to end when the display time ends. Therefore, the probability variation state and the short-time gaming state will continue until the next normal gaming state is reached and the game ball is won in the ordinary electric accessory 13 and the special symbol variation and stop display are completed.

  Next, the normal hit game state is completed, and the normal hit determination regarding the second game ball that has passed through the normal symbol start gate 12 is performed. Here, as described above, the length of the standby time of 23.2 after the ordinary electric accessory 13 is closed is a special symbol change / stop performed up to 5 times per ordinary hit. In addition, the jackpot game is set to a length that lasts after the time that the longest time is required and all ends. Therefore, the normal hit determination is not performed during the change of the special symbol or the big hit gaming state.

  In addition, as described above, the probability variation state and the short-time gaming state once generated continue until the stop display of the next special symbol is completed. Therefore, if the result of the jackpot determination performed at the closest time before the ordinary hit determination is made is “probability variation jackpot”, the ordinary hit determination is determined as “ordinary hit” with a probability of 718/719, The normal hit game and the big hit game are continued at shorter intervals than in the non-short-time game state, and a large number of game balls are paid out. On the other hand, if the result of the jackpot determination performed before the normal hit determination is “non-probability variation jackpot” or “out of”, it is determined to be a normal hit because it becomes a non-time-saving gaming state. The probability is 5/719, which is lower than in the short-time gaming state. Note that the gaming state does not change with the normal hit determination as an opportunity, and therefore, if it is determined to be “out” in the normal hit determination, the gaming state at that time is continued as it is. In the timing chart shown in FIG. 15, since the result of the jackpot determination performed before the second ordinary hit determination is “probability variation jackpot”, the ordinary hit determination is performed with a high probability of 718/719. Control similar to the above-described ordinary hit game and jackpot game is performed.

  Next, the opening / closing operation of the two special winning openings 16, 17 and the effect thereof, which is a feature of the present invention, will be described with reference to FIG. FIG. 16 is a timing chart of a big prize opening when a jackpot game is performed using one jackpot, and a timing chart of a big prize mouth when a jackpot game is played using two jackpots 16 and 17. FIG.

  First, a timing chart in the case where there is one special winning opening will be described. When it is determined as “big hit” by the big hit determination, the first big hit game is performed. As shown in FIG. 16, in the jackpot game, first, the big winning opening is opened for a maximum of 1.5 seconds. Then, when the first opening is completed, the second opening is performed. Here, a switch for detecting a winning game ball is provided at the big winning opening, but the time when the gaming ball actually enters the opened big winning opening and the time when the gaming ball is detected by the switch There is a time difference between Therefore, even a gaming machine configured to close the large winning opening on condition that a predetermined number of game balls have been detected may win more than a predetermined number of game balls. If enough time is not taken between the first closing and the second opening, the game balls detected during the second opening are awarded more than the prescribed number during the first opening. There is a case where it is impossible to determine whether the game ball is a game ball or a game ball won during the second opening. Therefore, when a jackpot game is played using one big winning opening, the second time after a sufficient closing time has passed to detect all the game balls that won the big winning opening during one opening. Need to be opened.

  During the closing time of the grand prize opening, the number of useless game balls that cannot be won in the big prize opening even though the game is a big hit game increases, and the number of game balls that the player can acquire decreases. There is a risk of damaging the interest. In addition, there is a problem that the time required for the jackpot game becomes longer by the closing time and the development of the game becomes slower. Further, there is a difference in the number of game balls to be paid out between a player who performs so-called stop hitting and stops a hitting player during the closing time. The example shown in FIG. 16 shows a case where a closing time of 3 seconds is provided between the first closing and the second opening. Then, within 2.7 seconds after the second closing, the next jackpot determination, special symbol variation, etc. are performed, and if the determination result is a jackpot, the second jackpot game is performed. As in the present embodiment, if a big hit game is being played until 0.4 seconds elapses after the second big prize opening is closed, the maximum time required for one big win game is 6.4 seconds. It becomes.

  Next, a timing chart of the pachinko machine 1 that is an embodiment to which the present invention is applied will be described. In the pachinko machine 1, two big winning mouths are used. As shown in FIG. 16, in the jackpot game, first, of the two large winning holes 16, 17, the first large winning hole 16 provided below is opened for a maximum of 1.5 seconds. This is the first opening. When the first opening is completed, the second big prize opening 17 provided above is opened. This is the second opening. In this way, in the pachinko machine 1, the first prize opening is different from the second prize opening, so that the other prize winning opening is opened for all the game balls that have been won. It can be detected smoothly while you are. Therefore, even when the time between the first closing and the second opening is shortened, or when the first closing and the second opening are performed at the same time, how many times the game balls detected by the switch are released. It is easy to determine whether the game ball has won a prize.

  As the interval between the first opening and the second opening is shortened, it is possible to reduce the frequency at which useless game balls that cannot be won in the special winning openings 16 and 17 are generated. Further, in this embodiment, the maximum time required for one jackpot game is 3.8 seconds, and the time required for the jackpot game is shortened compared to the case where there is one jackpot as described above. Will be faster. Furthermore, the interval between the first opening and the second opening is set to 0.4 seconds, which is shorter than the shooting interval of each game ball (in this embodiment, 0.6 seconds). This reduces the possibility that the number of useless game balls generated during closing of the winning prize openings 16 and 17 will be two or more, and makes it impossible to stop the game ball to be paid out. It is possible to prevent the difference in the number of pieces.

  Further, while the upper second big prize opening 17 is opened, the game balls guided to the big prize openings 16 and 17 by the game ball guiding member 22 (see FIGS. 1 and 2) are in the lower first big prize opening. Since the player wins the second big prize opening 17 before reaching 16, the game ball is unlikely to reach the vicinity of the first big prize opening 16. Therefore, even if the lower first major prize opening 16 is opened when the upper second major prize opening 17 is closed, the game ball is difficult to win the first major prize opening 16 immediately after the opening. . On the other hand, when the upper second big prize opening 17 is opened at the time when the lower first big prize opening 16 is closed, the game ball is still in the second big prize opening 17 even after opening. Easy to win. As shown in FIG. 16, in the present embodiment, the opening / closing operation of the two big winning holes 16 and 17 that are alternately performed once for each big hit game is performed from the lower first big winning hole 16. By performing first, a game ball can be easily won in the second big prize opening 17 which is opened immediately after the first big prize opening 16 is closed (after 0.4 seconds). Also, when the two big winning openings 16, 17 are opened and closed the same number of times (when the number of rounds of the jackpot game is an even number), as in the present embodiment where the number of rounds is two, The number of times that a series of “down, up” operations are performed in the order of “down, up, down, up” is repeated rather than repeated in the order of “up, down, up, down” Is one time. Accordingly, it becomes easier to win the game balls in the big winning openings 16 and 17.

  As described above, according to the pachinko machine 1 of the present embodiment, by alternately opening and closing the two large winning openings 16, 17, it is possible to win a large winning opening rather than repeatedly opening and closing one large winning opening. Unnecessary game balls that are not used can be reduced, and game development can be accelerated. In addition, since the act of stopping the launch of the game ball during the closing time of the special winning opening can be prevented, the difference in the number of game balls to be paid out can be reduced.

  Also, if the configuration is such that the open / close member is always opened during the jackpot game and the game balls can be stored on the open / close member of the big prize opening, so that the useless game balls are reduced, as in this embodiment. When applied to a gaming machine in which games are continuous, the opening / closing member must be closed between the jackpot game and the jackpot game, so that a great effect cannot be obtained. Furthermore, since it becomes necessary to detect a plurality of stored game balls at once, there is a possibility that the detection of the game balls cannot be performed smoothly. However, in this embodiment, since the time between the jackpot game and the jackpot game is shortened, the two big winning openings are alternately opened and closed alternately. You can reduce the ball. In addition, since one game ball is won at the other big prize opening while one big prize opening is closed, a plurality of stored game balls do not flow into the big prize opening and the detection of the game ball is possible. Smooth in a short time. Furthermore, in a gaming machine configured so that the opening / closing member is kept open during the jackpot game, it is difficult to know the so-called number of rounds, or the number of rounds currently being performed, but in this embodiment, the opening is performed. Since the big winning openings 16 and 17 are alternately changed for each round, the player can easily grasp the change of the round.

  In the present embodiment, the first grand prize opening 16 corresponds to the “first prize opening” of the present invention, and the second big prize opening 17 corresponds to the “second prize opening”. Further, the first big prize opening opening solenoid 70 for opening and closing the first big prize opening 16 and the second big winning opening opening solenoid 71 for opening and closing the second big prize opening 17 correspond to “winning prize opening and closing means”. In S125, S126, and S131 shown in FIG. 14, the CPU 51 of the main board 41 that controls the operations of the two large winning opening opening solenoids 70 and 71 functions as “winning opening / closing control means”. The ordinary electric accessory 13 corresponds to the “start opening” and “variable winning opening” of the present invention, and the start opening switch 72 provided in the ordinary electric accessory 13 corresponds to “start opening game ball detecting means”. . Further, in S84 shown in FIG. 12, the CPU 51 of the main board 41 that acquires the jackpot random number functions as a “big hit random number acquisition unit”, and the random number that is determined as the jackpot in S92 and S93 shown in FIG. The CPU 51 of the main board 41 that determines whether or not is a “big hit determination unit”.

  Further, the electric accessory opening solenoid 69 for opening and closing the ordinary electric accessory 13 corresponds to “variable starting port opening / closing means”, and the normal symbol starting gate 12 corresponds to “passing port”. Further, the normal symbol operation switch 73 provided in the normal symbol start gate 12 corresponds to “passage game ball detecting means”, and in S24 shown in FIG. "Random random number acquisition means". Further, in S32 and S36 shown in FIG. 10, the CPU 51 of the main board 41 for determining whether or not the normal hit is functioned as “normal hit determining means”. In S64 and S69 shown in FIG. The CPU 51 of the main board 41 that controls the operation corresponds to “variable start port opening / closing control means”.

  It should be noted that the present invention is not limited to the embodiment described in detail above, and various modifications can be made without departing from the scope of the present invention. First, in this embodiment, when it is determined that the jackpot is determined to be a big hit, the two big winning openings 16 and 17 are alternately opened and closed. If determined, the two ordinary electric accessories may be alternately opened and closed. That is, the present invention can be realized as long as it is a gaming machine provided with two winning openings having an opening / closing member.

  Further, the control of the gaming state based on the present invention is not limited to that exemplified in the above embodiment, and various changes can be made according to the specifications of the gaming machine. For example, it is possible to change the probability that the jackpot is determined to be a jackpot, the number of times the jackpots 16 and 17 are opened and closed during the jackpot game, the variation time of special symbols, and the like. In this embodiment, the time from closing one big prize opening to opening the other big prize opening is set to 0.4 seconds, but at the same time one big prize opening is closed, the other is opened. It can also be made.

  In the present embodiment, the second grand prize opening 17 is provided above the first grand prize opening 16 and the lower first major prize opening 16 is opened first. There is no need to arrange them side by side. For example, since many game balls move from left to right in the upper part of the game board 2, the upstream side in the direction in which the game balls flow down is the left side. Then, by arranging the first grand prize opening 16 on the right and the second big prize opening 17 on the left in the upper part of the game board 2, the game balls can be efficiently won in the two big prize openings 16, 17. Can do.

  In addition, as the gaming state generated in the present embodiment, there are provided a short-time gaming state and a non-short-time gaming state with different normal hit determination probability, and a probability variation state and a non-probability variation state with different jackpot determination probability. You can change this. For example, a gaming machine configured to generate only a short-time gaming state and a non-short-time gaming state without providing a probability variation state and a non-probability variation state can be achieved in a shorter time than in a non-short-time gaming state. It is possible to perform the same operation as that of the pachinko machine 1 in which the jackpots are continuous. In the present embodiment, ON / OFF of the probability variation flag and ON / OFF of the short-time state flag are synchronized. In other words, the probability variation state and the short-time gaming state are a set. There is no need to make it. That is, if it is configured to be able to determine the occurrence / end of the short-time gaming state at the time of jackpot determination, it can be changed to another form.

  In the present embodiment, since the short-time gaming state once generated is set to be switched to the non-short-time gaming state at the time when the special symbol stop display is finished next, it is determined to be “out” in the jackpot determination. When it is determined that, the short-time gaming state can be terminated. However, the short-time gaming state may be continued until it is determined next as “big hit”. In this case, the time-saving gaming state continues even when the jackpot determination is “out of”. Similarly, the condition for ending the probability variation state can be changed.

  Further, in this embodiment, after the normal hit state is reached, the length of the waiting time until the next normal hit determination is performed is a special symbol that is executed a maximum of five times with one normal hit as a trigger. Fluctuations / stops and jackpot games are set to a length that lasts longer than the time required to complete the longest time. However, the length of this waiting time can be shortened. In this case, there is a possibility that the normal winning determination may be performed during the change of the special symbol or during the jackpot game, but the short-time gaming state does not occur during the jackpot game. Furthermore, since the special symbol fluctuation time when the number of special symbol actuated balls is “0” is set shorter than the fluctuation time when the special symbol operation is not “0”, this allows normal hits during special symbol fluctuations. The possibility of making a determination is kept low. Therefore, even if the length of the waiting time is shortened, it is unlikely that the normal hit state is again made during the special symbol change or the big hit game, and the game contents are not complicated.

  The waiting time in this case is the time required to complete the five jackpot determinations in the shortest time when five game balls of the ordinary electric accessory 13 win, that is, five times. If it is shorter than the time required when all the jackpot determinations are determined to be “out of place” (hereinafter referred to as “minimum digestion time”), a normal hit determination must be made during special symbol changes or during jackpot games. become. Therefore, it is necessary to set the length of the waiting time to be longer than at least the “shortest digestion time”. Desirably, the fifth special symbol change, which is the last special symbol hold after the normal hit, is assumed, assuming that the longest time a special symbol variation / stop and jackpot game can be taken. The standby time may be set longer than the time to end. Thereby, the time interval between jackpot games can be shortened without complicating game contents. Even if the hit of the jackpot game is delayed and takes the longest time that can be assumed, the next normal hit judgment must be performed during the fifth jackpot game or after being judged as a deviation in the fifth jackpot judgment. become. In this embodiment, since the short-time gaming state is stopped during the big hit game, the probability of being determined to be a win in the normal hit determination is a low probability, and is determined to be roughly out of place. Therefore, the playability of the present embodiment is not impaired. As a case where the gameability is impaired, the case where the next normal hit determination is performed during the variation of each special symbol from the second time to the fifth time corresponds. In this case, the hit probability of the normal hit judgment may be high, and if the hit probability of the normal hit judgment becomes high according to the result of the last jackpot determination, the next normal hit gaming state is immediately There is a possibility that the gameability of the present embodiment, which is obtained in the above, is impaired. On the other hand, if the waiting time of the normal symbol is longer than the longest time until the fifth special symbol change ends, the normal hit judgment is performed during the second to fifth special symbol change. It can be avoided reliably and does not impair game play.

  In the present embodiment, the maximum number of reserved balls for a special symbol is “4”, so that a maximum of five jackpot games are played for each ordinary hit. Needless to say, the number of balls held can be changed. If the maximum number of reserved balls of the special symbol is changed, the maximum number of jackpot games to be played for one normal hit will also be changed, and according to this number, again after the normal hit game What is necessary is just to change suitably the length of the standby | waiting time until a normal hit determination is performed.
