When a signal is input from the touch sensor 112s and the operation volume 112a, the launch control circuit 320 performs control to energize the launch solenoid 112c provided in the game ball launch device to launch the game ball.

  The sub-control board 330 mainly controls each effect such as playing or waiting. The sub control board 330 includes a sub CPU 330a, a sub ROM 330b, a sub RAM 330c, and an RTC 330d, and is connected to the main control board 300 so as to be able to communicate in one direction from the main control board 300 to the sub control board 330. ing. The sub CPU 330a reads out a program stored in the sub ROM 330b based on a command transmitted from the main control board 300, an input signal from a timer, and the like, performs arithmetic processing, and controls the execution of effects. At this time, the sub RAM 330c functions as a data work area during the arithmetic processing of the sub CPU 330a.

  Specifically, the sub control board 330 performs image display control for displaying images on the main effect display unit 200a and the sub effect display unit 201a. The sub ROM 330b stores a large number of various image data to be displayed on the main effect display unit 200a and the sub effect display unit 201a. The sub CPU 330a reads the image data from the sub ROM 330b to a VRAM (not shown), and the main The image display of the effect display part 200a and the sub effect display part 201a is controlled.

  In addition, the sub-control board 330 performs the sound output control for outputting the sound from the sound output device 206 while moving the effect actor device 202 and controlling the lighting of the effect lighting device 204. Furthermore, when an operation detection signal is input from the effect button detection switch 208s that detects that the effect button 208 has been pressed, a predetermined effect is executed.

  Note that a power supply board (not shown) is connected to each board, and power is supplied to each board from a commercial power supply via the power supply board. The power supply board is provided with a backup power supply made of a capacitor. The RTC 330d provided on the sub control board 330 receives the power supply from this backup power supply and measures the current time.

  Next, games in the gaming machine 100 of the present embodiment will be described together with various tables stored in the main ROM 300b.

  As described above, in the gaming machine 100 of the present embodiment, two types of games, a special game and a normal game, proceed in parallel, and the low probability game state is used as the gaming state when proceeding with both of these games. Alternatively, the game progresses in any gaming state in which any gaming state in the high probability gaming state and any gaming state in the non-short-time gaming state or the short-time gaming state are combined.

  The details of each gaming state will be described later, but the low probability gaming state means that the probability of acquiring a right to execute a major game in which the first big prize opening 126 and the second big prize opening 128 are opened is set low. It is a gaming state, and a high probability gaming state is a gaming state in which the probability of acquiring a right to execute a big game is set high.

  The non-short game state is a game state in which the movable piece 122b is less likely to be in the open state and the game ball is less likely to enter the second start port 122. The short-time game state is more than the non-short game state. Also, the movable piece 122b is likely to be in an open state, and a game ball is likely to enter the second start port 122. Note that the initial state of the gaming machine 100 is set to a low-probability gaming state and a non-time-saving gaming state, and this gaming state is referred to as a normal gaming state in this embodiment.

  When the player operates the operation handle 112 to fire a game ball in the game area 116, and the game ball flowing down the game area 116 enters the first start port 120 or the second start port 122, the game is given to the player. A lottery for determining whether or not to give a profit (hereinafter referred to as a “larger lottery”) is performed. In this big game lottery, when the big win is won, the first big prize opening 126 and the second big prize opening 128 are opened, and the game balls enter the first big prize opening 126 and the second big prize opening 128. The possible big game is executed, and the game state after the end of the big game is set to one of the above game states. In the following, a lottery lottery method will be described.

  As will be described in detail later, when a game ball enters the first start port 120 or the second start port 122, various random numbers (big hit decision random number, hit symbol random number, reach group decision random number, reach reach) related to the big role lottery Mode decision random numbers and fluctuation pattern random numbers) are acquired, and each random number value is stored in the special figure storage area of the main RAM 300c. Hereinafter, various random numbers stored in the special figure holding storage area after the game ball has entered the first start port 120 are collectively referred to as special one hold, and the game ball enters the second start port 122. The various random numbers stored in the special figure storage area are collectively called special 2 reservation.

  The special figure reservation storage area of the main RAM 300c includes a first special figure reservation storage area and a second special figure reservation storage area. Each of the first special figure reservation storage area and the second special figure reservation storage area has four storage units (first to fourth storage units). When a game ball enters the first start port 120, the special 1 hold is stored in order from the first storage unit in the first special figure storage area, and when the game ball enters the second start port 122, the special ball is stored. 2 reservations are stored in order from the first storage unit of the second special figure storage area.

  For example, when a game ball enters the first start port 120, if no hold is stored in any of the first storage unit to the fourth storage unit of the first special figure storage area, the first memory is stored. The special 1 hold is stored in the department. Also, for example, when a game ball enters the first start port 120 in a state where special 1 hold is stored in the first storage unit to the third storage unit, the special 1 hold is stored in the fourth storage unit. Remember. In addition, even when a game ball enters the second start port 122, the special 2 reservation is stored in the first storage unit to the fourth storage unit of the second special figure storage area as described above. No special 2 reservation is stored in the storage unit with the smallest number (ordinal number).

  However, the number of special 1 reservations (X1) and the number of special 2 reservations (X2) that can be stored in the first special figure reservation storage area and the second special figure reservation storage area are each set to four. Therefore, for example, when a game ball enters the first start opening 120, if four special 1 reservations are already stored in the first special figure storage area, Special 1 hold is not newly stored by entering a game ball. Similarly, when a game ball enters the second start port 122 and four special 2 holds are already stored in the second special figure storage area, a game to the second start port 122 is stored. The special 2 hold is not newly memorized when the ball enters.

  FIG. 5 is a diagram illustrating a jackpot determination random number determination table. When a game ball enters the first start port 120 or the second start port 122, one big hit determination random number is acquired from the range of 0 to 65535. Then, when the big game lottery is started, that is, the jackpot determination random number determination table is selected according to the gaming state when the jackpot determination is performed, and the selected jackpot determination random number determination table and the acquired jackpot determination random number A lottery lottery is held.

  In the low probability gaming state, when starting the big lottery for special 1 hold and special 2 hold, as shown in FIG. 5A, the low probability big hit decision random number determination table is referred. According to the low probability jackpot determined random number determination table, when the jackpot determined random number is 10001 to 10164, it is determined to be a jackpot, and when it is any other jackpot determined random number, it is determined to be lost. Therefore, the jackpot probability in this case is about 1 / 399.6.

  Further, in the high probability gaming state, when starting the big lottery for the special 1 hold and the special 2 hold, as shown in FIG. According to the high-accuracy big hit decision random number determination table, if the big hit decision random number is 10001 to 10618, it is determined to be a big hit, and if it is any other big hit decision random number, it is determined to be a big hit. Therefore, the big hit probability in this case is about 1/106, and the small hit probability is about 1 / 1.01. As described above, in the case of a high probability gaming state, the jackpot probability is about four times that in the case of a low probability gaming state, and the player always wins a big or small hit.

  FIG. 6 is a diagram for explaining the winning symbol random number determination table. When a game ball enters the first start port 120 or the second start port 122, one winning design random number is acquired from the range of 0-99. Then, when the determination result of “big hit” or “small win” is derived by the above-mentioned big game lottery, the type of special symbol is determined by the acquired winning symbol random number and the winning symbol random number determination table. At this time, when the “big hit” is won by special 1 hold, as shown in FIG. 6A, the special random number determination table a for special 1 is selected, and “big win” is won by special 2 hold. In this case, as shown in FIG. 6B, the special 2 random number determination table a is selected. In addition, when “small hit” is won in the big game lottery, regardless of the type of holding, as shown in FIG. Hereinafter, a special symbol determined by a winning symbol random number, that is, a special symbol determined when a jackpot determination result is obtained is referred to as a jackpot symbol, and is determined when a small hit determination result is obtained. The special symbol is referred to as a small winning symbol, and the special symbol determined when a loss determination result is obtained is referred to as a lost symbol.

  According to the special symbol random number determination table a for special 1 shown in FIG. 6A and the special symbol random number determination table a for special 2 shown in FIG. 6B, according to the value of the acquired random symbol random number, As shown in the figure, the special symbol type (big hit symbol) is determined. Further, according to the small hitting design random number determination table shown in FIG. 6C, according to the value of the acquired winning design random number, the type of special symbol (small winning design) is determined as illustrated. On the other hand, if the lottery result is “losing” and the lottery result is derived by special 1 hold, the special symbol X is determined as the lost symbol without performing the lottery, and the lottery result is the special 2 When derived by holding, the special symbol Y is determined as a lost symbol without performing a lottery. That is, the winning symbol random number determination table is referred to only when the big drawing lottery result is “big win” or “small win”, and is not referred to when the big drawing lottery result is “losing”. Here, it is assumed that different jackpot symbols are respectively determined in the special 1 per symbol random number determination table and the special 2 per symbol random number determination table. However, the same jackpot symbol may be determined in both tables, or the special symbol type (jackpot symbol) may be determined with reference to the one symbol random number determination table regardless of the holding type. Good.

  FIG. 7 is a diagram for explaining a reach group determination random number determination table. A plurality of reach group determination random number determination tables are provided, and a preset table is selected according to the hold type, the hold number, the game state, the variation state associated with the game state, and the like. When a game ball enters the first start port 120 or the second start port 122, one reach group determination random number is acquired from the range of 0-10006. As described above, when the big drawing lottery result is derived, a process for determining a variation effect pattern for notifying the big drawing lottery result is performed. In the present embodiment, if the lottery result is “losing”, the group type is first determined by the reach group determination random number and the reach group determination random number determination table when determining the variation effect pattern. It should be noted that the change state is defined as which table is used to determine the change effect pattern, and is a concept set separately from the game state.

  For example, when the gaming state is set to the non-time-saving gaming state and the result of the “losing” leading role lottery result is derived based on the special 1 holding amount, the number of holdings of the special 1 holding amount when performing the leading role lottery ( Hereinafter, when the number of “holds” is simply 0), the reach group determination random number determination table 1 is selected as shown in FIG. Similarly, when the “Lossing” leading role lottery result is derived based on the special 1 hold when the normal gaming state is set, if the number of holdings when the leading role lottery is 1 to 2 As shown in FIG. 7B, when the reach group determination random number determination table 2 is selected and the number of holdings is 3, the reach group determination random number determination table 3 is selected as shown in FIG. 7C. Is done. In FIG. 7, a group x described in the group type column indicates an arbitrary group number. Therefore, various group numbers are determined as the group type according to the acquired reach group determination random number and the type of the reach group determination random number determination table to be referred to.

  Here, in the non-time-saving gaming state, the reach group determination random number determination table that is referred to when the “losing” leading role lottery result is derived based on the special 1 hold has been described. In addition, a number of reach group determination random number determination tables are stored.

  In addition, when the big director lottery result is “big hit” or “small win”, the group type is not decided when the variable effect pattern is decided. That is, the reach group determination random number determination table is referred to only when the lottery lottery result is “losing”, and is not referred to when the lottery lottery result is “big hit” or “small hit”.

  FIG. 8 is a diagram for explaining a reach mode determination random number determination table. This reach mode determination random number determination table is a lost mode reach mode determination random number determination table that is selected when the lottery lottery result is “losing”, and a jackpot that is selected when the lottery lottery result is “big hit” The hour reach mode determination random number determination table and the small hit hour reach mode determination random number determination table selected when the big lottery result is “small hit”. The lose mode reach mode determination random number determination table is provided for each group type determined as described above, and the big hit time reach mode determination random number determination table and the small hit time reach mode determination random number determination table are reserved types. It is provided for each. Each reach mode determination random number determination table is also provided for each gaming state and symbol type. Here, FIG. 8A shows an example of the group x lose time reach mode determination random number determination table referred to in the predetermined game state and symbol type, and an example of the special 1 jackpot time reach mode determination random number determination table. FIG. 8B shows an example of the special 2 jackpot hour reach mode determination random number determination table shown in FIG. 8C, and FIG. 8D shows an example of the special 1 jackpot hour reach mode determination random number determination table. Shown in

  When a game ball enters the first start port 120 or the second start port 122, one reach mode determination random number is acquired from the range of 0 to 250. If the result of the lottery lottery is “losing”, as shown in FIG. 8A, the lost reach mode random number corresponding to the group type determined by the group type lottery is shown. The determination table is selected, and the variation mode number is determined based on the selected lose time reach mode determination random number determination table and the reach mode determination random number. Further, when the result of the big game lottery is “big hit”, as shown in FIGS. 8B and 8C, the big hit hour reach mode determination random number determination table corresponding to the read hold type is shown. Is selected, and the variation mode number is determined based on the selected jackpot hour reach mode determination random number determination table and the reach mode determination random number. Furthermore, when the result of the above-mentioned big game lottery is “small hit”, as shown in FIG. 8D, the small hit hour reach mode determination random number determination table corresponding to the read hold type is selected. The variation mode number is determined based on the selected small hit hour reach mode determination random number determination table and the reach mode determination random number.

  In each reach mode determination random number determination table, the reach mode determination random number is associated with a change pattern random number determination table, which will be described later, together with the change mode number, and at the same time the change mode number is determined, the change pattern A random number determination table is determined. In FIG. 8, the table x described in the column of the variation pattern random number determination table indicates an arbitrary table number. Accordingly, the variation mode number and the table number of the variation pattern random number determination table are determined according to the acquired reach group determination random number and the type of the reach mode determination random number determination table to be referred to. In the present embodiment, the variation mode number and the variation pattern number described later are set in hexadecimal. In the following description, “H” is added to indicate a hexadecimal number, but “H” in FIGS. 8 to 10 indicates an arbitrary value indicated by a hexadecimal number.

  As described above, when the lottery lottery result is “losing”, first, the group type is determined by the reach group determination random number determination table and the reach group determination random number shown in FIG. Then, the variation mode number and the variation pattern random number determination table are determined based on the lost reach mode determination random number determination table and the reach mode determination random number shown in FIG.

  On the other hand, if the big lottery result is “big hit” or “small win”, the determined big hit symbol or small bonus symbol (special symbol type), the big win, or the gaming state at the time of winning the small bonus With reference to the corresponding reach mode determination random number determination table shown in FIG. 8, the variation mode number and the variation pattern random number determination table are determined using the reach mode determination random number.

  FIG. 9 is a diagram for explaining a variation pattern random number determination table. Here, a variation pattern random number determination table x of a predetermined table number x is shown, but many other variation pattern random number determination tables are provided for each table number.

  When a game ball enters the first start port 120 or the second start port 122, one variation pattern random number is acquired from the range of 0 to 238. Based on the variation pattern random number determination table determined simultaneously with the variation mode number and the obtained variation pattern random number, the variation pattern number is determined as illustrated.

  As described above, when the big character lottery is performed, the variation mode number and the variation pattern number are determined according to the result of the big character lottery, the determined symbol type, the gaming state, the number of holds, the hold type, and the like. These variation mode number and variation pattern number specify the variation effect pattern, and the variation effect mode and time are associated with each of them.

  FIG. 10 is a diagram for explaining the variation time determination table. As described above, when the variation mode number is determined, the variation time 1 is determined according to the variation time 1 determination table shown in FIG. According to this variation time 1 determination table, variation time 1 is associated with each variation mode number, and the corresponding variation time 1 is determined according to the determined variation mode number.

  As described above, when the variation pattern number is determined, the variation time 2 is determined according to the variation time 2 determination table shown in FIG. According to the variation time 2 determination table, the variation time 2 is associated with each variation pattern number, and the corresponding variation time 2 is determined according to the determined variation pattern number. The total time of the variation times 1 and 2 determined in this way becomes the variation production time for notifying the lottery result, that is, the variation time.

  When the variation mode number is determined as described above, a variation mode command corresponding to the determined variation mode number is transmitted to the sub control board 330, and when the variation pattern number is determined, the determined variation A variation pattern command corresponding to the pattern number is transmitted to the sub control board 330. In the sub control board 330, the first half of the variation effect is mainly determined based on the received variation mode command, and the second half of the variation effect is mainly determined based on the received variation pattern command. The details will be described later. Hereinafter, the variation mode number and the variation pattern number may be collectively referred to as variation information, and the variation mode command and the variation pattern command may be collectively referred to as a variation command.

  FIG. 11 is a first diagram illustrating the special electric accessory actuating ram set table, and FIG. 12 is a second diagram illustrating the special electric accessory actuating ram set table. The special electric accessory actuated ram set table stores various data for controlling the big player game or the small hit game. With reference to the table, the energization of the first big prize opening solenoid 126c and the second big prize opening solenoid 128c is controlled. In addition, there are multiple special electric accessory actuating ram set tables for each type of special symbol (big hit symbol and small hit symbol), and the special symbol type determined at the start of the big bonus game or small bonus game The corresponding table is set. Here, the big hit symbol control data is shown, and the small hit symbol control data is not shown.

  In this embodiment, special symbols A to M are provided as jackpot symbols, and a special symbol a is provided as a jackpot symbol. When the big winning symbol or the small winning symbol is determined, as shown in FIG. 11, a predetermined opening / closing pattern of the first big winning port 126 and the second big winning port 128 is set with reference to the special electric accessory operating ram set table. An opening / closing process for opening / closing control is executed. The big game is composed of a plurality of round games in which the first big prize opening 126 or the second big prize opening 128 is opened and closed a predetermined number of times, and the small hit game is executed only once.

  According to the special electric accessory actuated ram set table, the opening time (waiting time until the first round game is started), the maximum number of special electric accessory actuated (during one big game or small hit game) The number of round games executed), the open big prize opening (the first big prize opening 126 and the second big prize opening 128 opened in each round game), the number of times of opening / closing the special electric accessory (the first round game in the first round game) The number of times the first grand prize opening 126 and the second grand prize opening 128 are opened) and the solenoid energization time (the first grand prize opening solenoid 126c and the second large time for each opening frequency of the first big prize opening 126 and the second big prize opening 128). The energization time of the winning opening solenoid 128c, that is, the opening time of the first first winning opening 126 and the second second winning opening 128), the prescribed number (the first in the round game) The maximum possible number of winnings at the winning prize opening 126 and the second winning prize opening 128), the closing time of the closing prize opening time (the closing time of the first winning prize opening 126 and the second winning prize opening 128 between round games, ie, round Interval time), ending time (waiting time from the end of the last round game until normal special game is resumed), as control data of the big game, for each type of jackpot symbol as shown Is stored in advance.

  When the special symbols A, B, C, and E are determined as the jackpot symbols, the big game that is composed of four round games is executed.

During the first round game, when a prescribed number (8) of game balls enter the second grand prize opening 128 or when a predetermined time elapses after the second grand prize opening 128 is opened. The small hit game ends.

  As described above, in the big game, a round game in which the big prize opening is opened is executed a plurality of times, but the number of round games executed is set in advance for each type of jackpot symbol. Each jackpot symbol is set to a specific round game from among a plurality of round games to be executed. Normally, the movable member is held in a closed state that makes it impossible for the game ball to enter the probability variation area. However, during a specific round game, the movable member is switched from the closed state to the open state. Here, the operating conditions of the movable member, such as which round game is the specific round game and how the movable member is operated during the specific round game, are preset for each jackpot symbol. During the big game, the operation of the movable member is controlled according to the operation condition corresponding to the determined jackpot symbol.

  FIG. 13 is a diagram for explaining the operating conditions of the movable member. As shown in FIG. 13 (a), when the jackpot is won based on the special 1 hold, any of the special symbols A to D is determined as the jackpot symbol. According to the operating conditions set for the special symbol A, the first and third round games are defined as specific round games. In addition, each jackpot symbol includes, as operating conditions, the number of operating balls that is the number of game balls that enter the big prize opening for switching the movable member to the open state, and the time for controlling the movable member to the open state. Open time is specified. That is, in the present embodiment, in a specific round game, when the number of game balls that have entered the grand prize opening reaches a preset number of working balls, the movable member is changed from the closed state to the open state for a predetermined opening time. It will be switched.

  According to the operating conditions set for the special symbol A, one (1C) is specified as the number of operating balls for both the first and third round games, and 0.05 seconds is specified as the opening time. ing. Therefore, when the special symbol A is determined, in the first and third round games, when the first game ball enters the first grand prize opening 126, the first movable member 142 is 0.05 seconds. Only switches to the open state. The first big prize opening detection switch 126s for detecting the entry of a game ball into the first big prize opening 126 is arranged on the upstream side of the first probability variation area 140b. More specifically, the first big prize opening is such that the shortest time until the game ball detected by the first big prize opening detection switch 126s reaches the first probability variation area 140b is about 0.5 seconds, for example. The positional relationship between the detection switch 126s and the first probability variation region 140b is set. That is, when the special symbol A is determined, in the specific round game, the first probability change area 140b is in the open state, but the first moveable so that the game ball does not enter the first probability change area 140b. The member 142 will operate. Therefore, when the special symbol A is determined, the gaming state after the big game is a low probability gaming state.

  The operating conditions set for the special symbols B and C are the same as the operating conditions set for the special symbol A. Therefore, even when the special symbols B and C are determined, the gaming state after the big game is a low probability gaming state.

  Further, according to the operating conditions set for the special symbol D, the first, third and fifth round games are defined as specific round games. For the first and third round games, one (1C) is defined as the number of operating balls, and 0.05 seconds is defined as the open time. Therefore, even when the special symbol D is determined, the game ball does not enter the first probability variation area 140b in the first and third round games. On the other hand, for the fifth round game, one (1C) is defined as the number of working balls, and 20 seconds is defined as the opening time. Therefore, when the special symbol D is determined, in the fifth round game, when the first game ball enters the first big prize opening 126, the first movable member 142 is kept for 20 seconds. Switch to the open state. Thereby, when the special symbol D is determined, as long as the player appropriately fires the game ball, the gaming state after the big game is a high probability gaming state.

  As described above, when the jackpot is won by special 1 hold, the special symbol A is determined with a probability of 20%, the special symbols B and C are each 15%, and the special symbol D is determined with a probability of 50%. Therefore, when a big win is won by special 1 hold, the probability that the gaming state becomes a high probability gaming state is 50%.

  Further, as shown in FIG. 13B, when the jackpot is won based on the special 2 hold, any of the special symbols E to M is determined as the jackpot symbol. The operating conditions set for the special symbol E are the same as the operating conditions set for the special symbols A, B, and C. Therefore, even when the special symbol E is determined, the gaming state after the big game is a low probability gaming state.

  On the other hand, according to the operating conditions set for the special symbols F to L, the first and third round games are defined as specific round games. For the first and third round games, 1 (1C) and 2 (2C) are defined as the number of working balls, and 0.05 seconds and 20 seconds are defined as the open times, respectively. Therefore, for example, when the special symbol F is determined, in the first round game, when the first game ball enters the second big prize opening 128, the second movable member 152 is only 0.05 seconds. Switch to the open state. The shortest time required for the game ball detected by the second big prize opening detection switch 128s to reach the second probability variation area 150b is, for example, about 0.5 seconds, and the second big prize opening detection switch 128s and the second A positional relationship with the two-probability variation region 150b is set. Therefore, when the special symbol F is determined, in the first round game, the first game ball that has entered the second big winning opening 128 does not enter the second probability variation area 150b.

  However, when the second game ball enters the second grand prize opening 128 in the first round game, the second movable member 152 is maintained in the open state for 20 seconds. Therefore, when the special symbols F to L are determined, if the player has appropriately fired the game ball, the game ball enters the second probability variation area 150b in the first round game, and after the big game The gaming state becomes a high probability gaming state.

  According to the operating conditions set in the special symbols F to L, the same number of operating balls and the same opening time as the first round game are defined for the third round game. Therefore, even if the game ball does not enter the second probability variation area 150b during the first round game, for example, when the player stops the launch of the game ball, the third round game again An opportunity to enter the game ball into the 2-probability changing region 150b is given.

  Further, according to the operating conditions set in the special symbol M, the first and third round games are defined as specific round games. For the first round game, one (1C) is defined as the number of working balls, and 0.05 seconds is defined as the open time. In addition, for the third round game, 1 (1C) and 5 (5C) are defined as the number of working balls, and 0.05 seconds and 20 seconds are defined as the open times, respectively. Therefore, when the special symbol M is determined, in the third round game, when the fifth game ball enters, the game ball enters the first probability variation area 140b. Thereby, when the special symbol M is determined, as long as the player appropriately fires the game ball, the game state after the major role game becomes the high probability game state.

  FIG. 14 is a diagram illustrating a game state setting table for setting the game state after the end of the big game. In the present embodiment, when a big game is executed, the game state after the completion of the big game is set according to the determined special symbol and the presence or absence of the game ball entering the probability variation area during the specific round game. The

  According to this game state setting table, regardless of the determined special symbol type, if a game ball enters the probability variation area during the big game, the high probability game state is set after the big game is completed. The number of continuations of the high-probability gaming state (hereinafter referred to as “high-probability number”) is set to 170 times. This means that the high-probability gaming state continues until the big lottery result is confirmed 170 times. However, the above-mentioned high-accuracy count indicates the maximum number of continuations in the high probability gaming state of 1. If the big hit is won before reaching the above-mentioned continuation count, the high-probability count is set again. Will be performed. Therefore, when the high-probability gaming state is set after the end of the big game, the lottery result for the loss or the small-bonus is derived 170 times without being derived in the high-probability gaming state. The gaming state is changed to the low probability gaming state. In addition, regardless of the determined special symbol type, if the game ball does not enter the probability variation area during the big game, the low probability game state is set after the big game.

  In addition, when a game ball enters the probability changing area during the big game, the short-time game state is set after the completion of the big game, and the duration of the short-time game state (hereinafter referred to as “short-time number”) is 170 times. Set to This means that the short-time gaming state continues until the big-lot lottery result is confirmed 170 times. However, the above-mentioned number of short times indicates the maximum number of times of continuation in the short time gaming state of 1, and if the big hit is won before reaching the above number of continuations, the setting of the number of short times is performed again. It will be. Further, when the game ball does not enter the probability variation area during the big game, regardless of the type of the special symbol, the non-time-saving game state is set.

  As described above, according to the present embodiment, the first probability variation area 140b, the open state that allows the game ball to enter the first probability variation area 140b, and the open state are provided in the first grand prize opening 126. And a first movable member 142 that switches to a closed state that makes it difficult (impossible) to enter the game ball into the first probability variation region 140b. In addition, the second probability variation area 150b, an open state in which the game ball can enter the second probability variation area 150b, and the game ball entering the second probability variation area 150b from the open state are entered into the second major winning opening 128. And a second movable member 152 that switches to a closed state that makes entry difficult (impossible). In a specific round game set in advance in a round game, when a game ball enters the first probability variation area 140b or the second probability variation area 150b, the gaming state is set to a high probability gaming state, and the first probability variation area If the game ball does not enter either 140b or the second probability variation area 150b, the gaming state is set to the low probability gaming state.

  In this way, there is a possibility that the game ball may enter the probability variation area at each of the two big winning holes, so that the player's willingness to play can be improved in all round games.

  In addition, the first movable member 142 or the second movable member 152 is operated according to the operation condition set for each jackpot symbol, and at the first round winning opening 126 or the second large winning opening 128 in a specific round game. When the number of played balls reaches the number of working balls, the first movable member 142 or the second movable member 152 is switched to the open state. This makes it unclear at which timing the game ball can enter the probability variation area.

  For example, as shown in FIG. 13B, when the special symbol E and the special symbol M are compared, the round game of the same number of times (1R and 3R) is set as the specific round game among the plurality of round games. However, the number of times that the movable member is switched to the open state in the specific round game is different between the two jackpot symbols. That is, in the special symbol E, the first movable member 142 is switched to the open state only once in the third round game, whereas in the special symbol M, the first movable member 142 is switched in the third round game. Switch to the open state twice. In this way, by changing the number of times the movable member is switched to the open state during one specific round game depending on the operating conditions, unexpectedness and expectation are given to the player, and the game motivation during the big game This can be further improved.

  In addition, even if the number of times the movable member is switched to the open state in one specific round game is the same, for example, the jackpot symbol with the first working ball number and the jackpot with the fifth working ball number By providing two or more jackpot symbols that differ from each other in the number of operating balls specified, such as symbols, the player will be given unexpectedness and expectation, and will further improve the willingness to play during a big game. Can do.

  Also, for example, as shown in FIG. 13 (a), according to the operating conditions set for the special symbol A, the first and third round games are defined as specific round games and set to the special symbol D. According to the operated conditions, the first round game, the third round game, and the fifth round game are defined as specific round games. In this way, by providing two or more jackpot symbols in which different times among a plurality of round games are set as a specific round game, unexpectedness and expectation are given to the player, and the game during the big game The motivation can be further improved.

  FIG. 15 is a diagram for explaining the hit determination random number determination table. When a game ball flowing down the game area 116 passes through the gate 124, a normal symbol determination process (hereinafter referred to as “normal drawing lottery”) associated with whether or not to energize the movable piece 122b of the second start port 122 is controlled. ) Is performed.

  As will be described in detail later, when the game ball passes through the gate 124, one hit-determined random number is acquired from the range of 0 to 99, and four random number values are stored in the general-purpose reserved storage area of the main RAM 300c. Is stored as the upper limit. That is, the usual-pending storage area includes four storage units that save the winning random numbers. Accordingly, when a game ball passes through the gate 124 in a state in which the hit random numbers are stored in all the four storage units of the usual reserved storage area, the hit random numbers are stored based on the passage of the game balls. There is nothing. Hereinafter, the winning random number stored in the usual figure storage area after the game ball passes through the gate 124 is referred to as the usual figure holding.

  When the general drawing lottery is started in the non-short game state, as shown in FIG. 15 (a), the determined random number determination table for non-short game state is referred. According to the per-determined random number determination table for the non-short-time gaming state, when the hit determined random number is 0, the hit symbol is determined as the normal symbol type, and when the hit determined random number is 1 to 99, The lost symbol is determined as the normal symbol type. Therefore, the probability that the winning symbol is determined in the non-short game state, that is, the winning probability is 1/100. As will be described in detail later, when the winning symbol is determined in this general drawing lottery, the second starting port 122 is controlled to be in the open state, and when the lost symbol is determined, the second starting port 122 is in the closed state. Maintained.

  In addition, when the general drawing lottery is started in the short-time gaming state, as shown in FIG. 15B, the per-determined random number determination table for the short-time gaming state is referred. According to the per-determined random number determination table for the short game state at this time, when the winning determined random number is 0 to 98, the winning symbol is determined as the normal symbol type, and when the winning determined random number is 99, A lost symbol is determined as the symbol type. Therefore, the probability that the winning symbol is determined in the short-time gaming state, that is, the winning probability is 99/100.

  FIG. 16A is a diagram for explaining a normal symbol variation time data table, and FIG. 16B is a diagram for explaining an opening / closing control pattern table. As described above, when the regular drawing lottery is performed, the variation time of the normal symbol is determined. The normal symbol variation time data table is referred to when determining the variation time of the normal symbol when the winning symbol or the lost symbol is determined by the general symbol lottery. According to this normal symbol variation time data table, when the gaming state is set to the non-short-time gaming state, the variation time is determined to be 10 seconds, and when the gaming state is set to the short-time gaming state, the variation Time is determined to be 1 second. When the variation time is determined in this way, the normal symbol display 168 is varied and displayed (flashing display) over the determined time. When the winning symbol is determined, the normal symbol display 168 is turned on, and when the lost symbol is determined, the normal symbol display 168 is turned off.

  When the winning symbol is determined by the general symbol lottery and the normal symbol indicator 168 is lit, the movable piece 122b of the second start port 122 is opened and closed as shown in FIG. 16B. The energization is controlled with reference to the table. Actually, the opening / closing control pattern table is provided for each gaming state, and the corresponding table is set at the start of energization of the ordinary electric accessory solenoid 122c according to the gaming state when the ordinary symbol is determined. However, here, for convenience of explanation, control data corresponding to each gaming state is shown in one table.

  When the winning symbol is determined, as shown in FIG. 16B, the second start port 122 is controlled to open and close with reference to the opening and closing control pattern table. According to this open / close control pattern table, the time before the opening of the normal electric power (the waiting time until the opening of the second start port 122 is started), the maximum number of switching times of the normal electric accessory (the number of times of opening the second start port 122) , Solenoid energization time (the energization time of the ordinary electric accessory solenoid 122c every time the second start port 122 is opened, that is, one open time of the second start port 122), the specified number (the total of the second start port 122) The maximum possible number of winnings at the second start port 122 during opening), the ordinary power closing time (the closing time between each opening of the second starting port 122, that is, the rest time), the normal power effective state time (second starting) The waiting time from the end of the last opening of the mouth 122), the waiting time for the end of ordinary power transmission (the waiting time until the normal symbol variation display to be described later is resumed after elapse of the ordinary power transmission valid time) 122 control data To, for each gaming state, is stored in advance as shown.

  As described above, the non-time-saving gaming state and the time-saving gaming state are associated with the opening / closing control conditions for opening and closing the second start port 122 as the game progress conditions. It becomes easier for a game ball to enter the second starting port 122 than in the gaming state. In other words, in the short-time gaming state, as long as the game ball passes through the gate 124, the lottery is drawn one after another, and the second start port 122 is frequently opened, so that the player can use the game ball. It becomes possible to perform a lottery lottery while reducing.

  The opening / closing condition of the second start port 122 defines three elements: the normal symbol winning probability, the normal symbol variation display time, and the second start port 122 opening time. In the present embodiment, in these two elements, the time-short gaming state is set more advantageously than the non-time-short gaming state, so that the time-short gaming state is the second start than the non-time-short gaming state. It was set so that game balls could easily enter the mouth 122. However, among the above three elements, one or three elements may be set more advantageously in the short-time gaming state than in the non-short-time gaming state. In any case, the short-time gaming state is advantageous for at least one element compared to the non-short-time gaming state, so that the time-short gaming state is comprehensively more advantageous than the non-time-short gaming state. What is necessary is just to make a game ball enter into 122 easily. That is, when the gaming state is set to the non-short-time gaming state, the movable piece 122b is controlled to open and close according to the first condition, and when the gaming state is set to the short-time gaming state, It is sufficient that the movable piece 122b is controlled to open and close according to the second condition that tends to be in the open state.

(Step S300-25)
The main CPU 300a determines whether the counter value of the loop counter is not zero. As a result, if it is determined that the counter value is not 0, the process proceeds to step S300-19, and if it is determined that the counter value is 0, the process proceeds to the CPU initialization process (step S100).

  Note that when the power is actually cut off, the operation of the gaming machine 100 is stopped while the steps S300-17 to S300-25 are looped.

(Timer interrupt processing of main control board 300)

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Is done.

  For example, in the above-described embodiment, when the high probability gaming state is set, the game ball gradually increases in number of game balls due to the small hit game, but such game property is only an example. In addition, the game characteristics such as the special symbol type, the big game, the content of the small hit game, and the content of the game state in the above embodiment are merely examples. Therefore, in the above embodiment, the high probability game state and the low probability game state, or the short time game state and the non-short time game state are provided, but the short time game state (non-short time game state) is not essential, and Small hits are not essential.

  In any case, when the starting condition is satisfied, any symbol is determined from the symbols including the lost symbol and multiple types of jackpot symbols, and when the predetermined fluctuation time has elapsed since the symbol was determined, the symbol is displayed. When the display is stopped and the jackpot symbol is stopped and displayed on the symbol display unit, a round game is executed a plurality of times by controlling the opening and closing of the big prize opening provided in the game area, and a predetermined number of round games are set in advance. In a specific round game, if a game ball enters the probability variation area, the game state is set to a high probability game state.
