Description

[Technical field]

[0001] The present invention relates to a gaming machine. [Background technology]

[0002] Conventionally, in a pachinko game machine, which is a type of game machine, a jackpot lottery is held in response to a game ball entering the first start ball entry port or the second start ball entry port, and a symbol change game is executed based on the result of the jackpot lottery. When a jackpot display result is displayed in the symbol change game, a jackpot game is awarded in which the special ball entry port is opened. When a normal symbol change game is executed in response to a game ball entering the normal start port, a normal win display result is displayed in the normal symbol change game, and a normal win game is awarded in which the second start port is opened.

[0003] Among such pachinko gaming machines, those that are generally controlled to various game states, for example, as in Patent Document 1. The game states include, for example, a non-entry rate improvement state and an entry rate improvement state in which the game ball is more likely to enter the second starting entry hole than in the non-entry rate improvement state, and the entry rate improvement state is a game state that is more advantageous to the player than the non-entry rate improvement state.

[0004] In addition, such a pachinko game machine is configured to be controlled to the ball winning rate improved state after the end of the jackpot game, and in addition to the fact that the jackpot game has been awarded, it is possible to heighten the expectation of being controlled to the ball winning rate improved state after the end of the jackpot game. Also, when the machine is controlled to the ball winning rate improved state after the end of the jackpot game, it may be controlled to the non-ball winning rate improved state when the number of times the symbol variation game executed after the end of the jackpot game has been executed reaches a predetermined number of times.

[0010] [First embodiment] An embodiment of a pachinko gaming machine will be described below. In this specification, up, down, left, right, front (front), and back (back) indicate the respective directions as seen by the player.

[0011] As shown in Fig. 1, a pachinko gaming machine 10 serving as a gaming machine includes a frame 11. The frame 11 is a member for mounting various components such as a game board 20. The pachinko gaming machine 10 is equipped with a launch handle 16. For example, the launch handle 16 is provided on the front side of the frame body 11. In the pachinko gaming machine 10, game balls (game media) are launched toward a game area 21 of a game board 20 with strength according to the amount of operation (amount of rotation) of the launch handle 16. In other words, the pachinko gaming machine 10 is configured so that the launch strength of the game balls can be adjusted by operating the launch handle 16.

[0012] The pachinko game machine 10 is equipped with a decorative lamp 17. For example, the decorative lamp 17 is provided on the front side of the frame body 11. The decorative lamp 17 has a built-in light-emitting body (not shown) and is configured to be able to emit light, blink, and turn off by the light-emitting body. The decorative lamp 17 executes an effect of emitting light, blinking, and turning off (hereinafter referred to as a light-emitting effect) as one of the effects.

[0013] The pachinko game machine 10 is equipped with a speaker 18. For example, the speaker 18 is provided on the front side of the frame body 11. As one of the effects, the speaker 18 executes an effect (hereinafter, referred to as an audio effect) of outputting sounds such as human or animal voices, sound effects, and music.

[0014] The pachinko game machine 10 is provided with an operation button 19 at a position on the front side of the frame 11 where the operation button 19 can be operated by the player. The operation button 19 is used, for example, during performance. The operation button 19 may also be used, for example, during various settings such as volume setting and light setting.

[0015] The pachinko gaming machine 10 includes an information display device 22. For example, the information display device 22 is provided at a position on the gaming board 20 that is visible to the player. The information display device 22 notifies various information indicating the control state of the pachinko gaming machine 10.

[0016] The information display device 22 includes a first special symbol display section 22a as a game execution means. The first special symbol display section 22a is configured to be capable of displaying one or more types of first special symbols. The first special symbol display section 22a executes a first special symbol changing game (first symbol changing game) as a special symbol changing game, in which a predetermined symbol is changed and displayed, and the first special symbol is finally displayed as a fixed and stopped symbol. In the following description, the "first special symbol changing game" may be abbreviated to "first special game."

[0017] The information display device 22 includes a second special symbol display section 22b as a game execution means. The second special symbol display section 22b is configured to be capable of displaying one or more types of second special symbols. The second special symbol display section 22b executes a second special symbol changing game (second symbol changing game) as a special symbol changing game, in which a predetermined symbol is changed and a second special symbol is finally displayed as a fixed and stopped symbol. In the following description, the "second special symbol changing game" may be abbreviated to "second special game."

[0018] In the following description, when the first special symbol changing game and the second special symbol changing game are not distinguished from each other, they may be collectively referred to as "special symbol changing game (symbol changing game)" and the special symbol changing game may be referred to as "special game". In other words, the special game includes a first special game and a second special game. The first special symbol and the second special symbol are symbols for notifying the result of a lottery (a big win lottery to be described later) that is internally executed in the pachinko game machine 10.

[0019] In this specification, "variable display" means a state in which the type of the displayed pattern changes over time. In this specification, "determined stop display" means a state in which the pattern is definitively displayed and the type of the displayed pattern does not change. In this specification, "determined stop display" and "derive" have the same meaning when it comes to patterns. The special patterns that can be derived in the first special pattern display section 22a and the second special pattern display section 22b include a jackpot pattern as a jackpot display result and a miss pattern as a miss display result. When a jackpot pattern is derived in a special game, the player can recognize that it will be a jackpot. When a miss pattern is derived in a special game, the player can recognize that it will be a miss.

[0020] In this embodiment, the first special game and the second special game are not executed simultaneously. In this embodiment, the second special game is executed in priority to the first special game. In this embodiment, when the jackpot lottery is won, a jackpot symbol is derived in the special game, and the jackpot game is awarded after the special game ends. In other words, the jackpot game is awarded after the special game in which the jackpot lottery is won ends. As will be described in detail later, the jackpot game is a game in which a large number of prize balls can be won, and is therefore an advantageous game (state) for the player.

[0021] In this embodiment, after the special symbol is displayed as a fixed stop and the special game ends, a variable interval time ("0.5 seconds" in this embodiment) is specified as the time until the start of the next special game is permitted. In other words, the variable interval time is the time from the end of the current special game until the start of the next special game is permitted. In other words, the variable interval time is the time until the start of the next special game is permitted, and can also be said to be the time until the start of a jackpot game or the start of a standby state is permitted. The standby state is a state in which neither a variable game nor a jackpot game is being played.

[0022] The information display device 22 includes a first special hold display section 22c. The first special hold display section 22c displays information that allows the user to recognize the number of first special games whose execution has been put on hold because the hold condition has been met but the execution condition has not yet been met. In the following description, the number of first special games that have been put on hold is referred to as the "first special hold number."

[0023] The information display device 22 includes a second special hold display section 22d. The second special hold display section 22d displays information that allows the user to recognize the number of second special games whose execution has been put on hold because the hold condition has been met but the execution condition has not yet been met. In the following description, the number of second special games that have been put on hold is referred to as the "second special hold number."

[0024] For example, the maximum value of the first special reserved number and the second special reserved number is "4." In this way, the execution of the special game can be reserved up to the predetermined reserved number (reserved upper limit number). The information display device 22 includes a normal symbol display section 22e. The normal symbol display section 22e is configured to be capable of displaying one or more types of normal symbols. The normal symbol display section 22e is capable of executing a normal symbol variation game in which a predetermined symbol is variably displayed and a normal symbol is finally displayed as a fixed stop. In the following description, the normal symbol variation game is abbreviated to "normal game". The normal symbols that can be derived to the normal symbol display section 22e include a normal winning symbol and a normal losing symbol. When a normal winning symbol is derived in the normal game, the player can recognize that a normal winning has occurred. When a normal losing symbol is derived in the normal game, the player can recognize that a normal losing has occurred. In this embodiment, when a winning lottery for a normal symbol is won, a normal winning symbol is derived in the normal game, and a normal winning game is awarded after the normal game ends. As will be described in more detail later, normal winning gameplay is advantageous to the player because it makes it easier to establish the reservation conditions for the second special game.

[0025] The information display device 22 includes a regular hold display section 22f. The regular hold display section 22f displays information that allows the user to recognize the number of regular games that have been held for execution because the hold condition has been met but the execution condition has not yet been met. For example, the maximum number of regular holds is "4."

[0026] Next, the game board 20 will be described. The game board 20 has a surface side (front side) of the game board 20 divided into a substantially circular shape by rails, forming a game area 21. The pachinko game machine 10 also has a center frame 26 decorated with various ornaments in the substantially center of the game area 21. The center frame 26 has an opening 26a. The center frame 26 may also be referred to as a center role.

[0027] The pachinko gaming machine 10 is equipped with a performance display device 27 as a performance execution means. The performance display device 27 is equipped with a display area 27r in which an image is displayed. The performance display device 27 is attached to the game board 20 so that the player can view the display area 27r through the opening 26a of the center frame 26. The performance display device 27 executes a performance (hereinafter referred to as a display performance) in which an image (picture) imitating a predetermined character or letter is displayed as one of the performances. The performance display device 27 also executes a predetermined notification performance.

[0028] In this embodiment, the display effects that the effect display device 27 can execute include an effect pattern change game in which effect patterns are variably displayed in multiple rows and a combination of effect patterns is ultimately derived. In the following explanation, the effect pattern change game is abbreviated to "effect game." The effect patterns are patterns (decorative patterns) decorated with characters, patterns, etc., and are intended to diversify the display effects. In this embodiment, the effect game is performed by variably displaying (scrolling) the first, second, and third pattern rows in a predetermined direction, respectively.

[0029] The effect game is started with the start of the special game and is ended with the end of the special game. In the effect game, a combination of effect symbols corresponding to the special symbols derived in the special game is derived. When a big win symbol is derived in the special game, a big win symbol combination by the effect symbols is derived in the effect game. For example, the big win symbol combination by the effect symbols is a symbol combination in which the effect symbols of all columns are the same, such as "333" or "777". When a losing symbol is derived in the special game, a losing symbol combination by the effect symbols is derived in the effect game. For example, the losing symbol combination by the effect symbols is a symbol combination in which the effect symbols of at least some columns are different from the effect symbols of the other columns, such as "787" or "556". In the effect game, the effect symbols may be stopped once before being displayed as a fixed stop. In this specification, the term "temporarily stopped display" refers to a temporary stop state before the performance pattern is displayed in a definite stopped state, for example, a state in which the performance pattern is displayed in a fluctuating manner.

[0030] The performance game may include a reach performance that is performed by forming a reach. A reach is a state in which the same performance symbol is temporarily displayed in a specific column (the first column and the third column in this embodiment) among multiple columns, and a performance symbol in a column other than the specific column (the second column in this embodiment) is continuously displayed in a variable manner. For example, the reach performance may include multiple types of reach performances in which the characters that appear and the actions of the performance symbols are different.

[0031] The pachinko game machine 10 is provided with a first start port 28 that opens into the game area 21 below the center frame 26. The first start port 28 is always open so that game balls can enter. That is, the first start port 28 as the first start ball entry port is capable of receiving game balls. The pachinko game machine 10 is provided with a first start sensor SE1 that detects game balls that have entered the first start port 28. For example, the first start sensor SE1 is provided in a passage through which the game balls that have entered the first start port 28 pass. In this embodiment, when the first start sensor SE1 detects a game ball, a reservation condition for the first special game can be established and a payout condition for prize balls is established. That is, the first special game can be executed in response to the entry of a game ball into the first start port 28.

[0032] The pachinko game machine 10 is provided with a second start port 29 that opens into the game area 21 below the center frame 26. That is, the second start port 29 as a second start ball entry port is capable of receiving a game ball. The pachinko game machine 10 is provided with a second start sensor SE2 that detects a game ball that has entered the second start port 29. For example, the second start sensor SE2 is provided in a passage through which the game ball that has entered the second start port 29 passes. In this embodiment, when the game ball is detected by the second start sensor SE2, the reservation condition of the second special game can be established and the payout condition of the prize ball is established. That is, the second special game can be executed in response to the entry of the game ball into the second start port 29.

[0033] The pachinko game machine 10 is provided with a normal variable member 30 that can be operated in a permissive state (open state) and a restricted state (closed state) in the game area 21. The permissive state is a state in which the game ball can be inserted into the second start hole 29 or is easy to insert. The restricted state is a state in which the game ball cannot be inserted into the second start hole 29 or is difficult to insert. The pachinko game machine 10 is provided with a normal actuator A1 that operates the normal variable member 30 (shown in FIG. 6). The normal variable member 30 is operated to the permissive state in a normal winning game. In this way, the normal variable member 30 as an opening / closing member operates so that the second start hole 29 can take the permissive state in a predetermined open mode in a normal winning game.

[0034] The pachinko gaming machine 10 has a special winning opening 31 that opens into the gaming area 21 at the lower right of the center frame 26. In other words, the special winning opening 31, which serves as a special ball opening, is capable of receiving a game ball. The pachinko gaming machine 10 has a special winning sensor SE3 that detects a game ball that has entered the special winning opening 31. For example, the special winning sensor SE3 is provided in a passage through which the game ball that has entered the special winning opening 31 passes. In this embodiment, when a game ball is detected by the special winning sensor SE3, a condition for paying out a prize ball is established.

[0035] The pachinko game machine 10 is provided with a special variable member 32 that can be operated in a permissive state (open state) and a restricted state (closed state) in the game area 21. The permissive state is a state in which the game ball can be entered into the big prize opening 31 or is easy to enter. The restricted state is a state in which the game ball cannot be entered into the big prize opening 31 or is difficult to enter. The pachinko game machine 10 is provided with a special actuator A2 that operates the special variable member 32 (shown in FIG. 6). The special variable member 32 is operated to the permissive state during a big win game. In this way, the special variable member 32 as a special opening / closing member is operable so that the big prize opening 31 can be in the permissive state and the restricted state during a big win game.

[0036] The pachinko game machine 10 is provided with a special passage area 36 and a normal passage area 37 downstream of the large prize opening 31 through which the game ball that entered the large prize opening 31 can pass. The passage through which the game ball that entered the large prize opening 31 passes is a passage that branches into a first passage and a second passage, and the special passage area 36 is provided in the first passage, and the normal passage area 37 is provided in the second passage. In other words, the special passage area 36 and the normal passage area 37 are passable by the game ball that entered the large prize opening 31.

[0037] The pachinko game machine 10 is equipped with a special passage sensor SE6 that detects a game ball that has passed through the special passage area 36. In this embodiment, when the special passage sensor SE6 detects a game ball, a high probability state is provided after the end of the big win game. In this way, the special passage sensor SE6 detects that the game ball that entered the big win opening 31 has passed through the special passage area 36 (the game ball that has passed through the special passage area 36).

[0038] The pachinko game machine 10 is provided with a distribution member 38 that can be operated between a first distribution state and a second distribution state at a point where a passage through which a game ball that has entered the large prize opening 31 passes branches. The first distribution state is a state in which a game ball that has entered the large prize opening 31 can be distributed to a special passing area 36. The second distribution state is a state in which a game ball that has entered the large prize opening 31 can be distributed to a normal passing area 37. The pachinko game machine 10 is provided with a distribution actuator A3 that operates the distribution member 38 (shown in FIG. 6). The distribution member 38 operates to be able to take the first distribution state and the second distribution state, and can be operated from the second distribution state to the first distribution state during a big win game.

[0039] The pachinko game machine 10 is provided with a gate 33 through which a game ball can pass (enter) on the right side of the center frame 26 in the game area 21. That is, the gate 33 as a normal start ball entry port is capable of receiving a game ball. The gate 33 is provided with a gate sensor SE4 that detects a game ball passing through the gate 33 (shown in FIG. 6). In this embodiment, when a game ball is detected by the gate sensor SE4, a reserve condition for a normal game can be established. Then, a normal winning lottery is held in response to the game ball entering the gate 33, and the normal winning lottery is won and a normal winning game is awarded. That is, a normal winning game may be awarded in response to the game ball entering the gate 33.

[0040] The pachinko gaming machine 10 is provided with a general winning opening 34 that opens into the gaming area 21 to the right of the center frame 26. The pachinko gaming machine 10 is provided with a general winning sensor SE5 that detects a gaming ball that has entered the general winning opening 34 (shown in FIG. 6). For example, the general winning sensor SE5 is provided in a passage (not shown) through which the gaming ball that has entered the general winning opening 34 passes. In this embodiment, when a gaming ball is detected by the general winning sensor SE5, a payout condition for a prize ball is established. The pachinko gaming machine 10 may be provided with multiple general winning openings.

[0041] The pachinko game machine 10 of this embodiment is provided with a first start opening 28, a second start opening 29, a big prize opening 31, and a general prize opening 34 as winning openings. The pachinko game machine 10 may be provided with winning openings other than the above winning openings. A "winning" is when a game ball enters a winning opening. The pachinko game machine 10 is also provided with components such as nails and windmills for changing the behavior of the game ball flowing down the play area 21.

[0042] Next, the gaming state of the pachinko gaming machine 10 will be described. The pachinko game machine 10 has a low probability state and a high probability state as game states with different jackpot probabilities. The jackpot probability is the probability of winning a jackpot in a jackpot lottery. The high probability state is a game state in which the jackpot probability is higher than in the low probability state. In other words, the high probability state is a game state in which it is easier to win a jackpot lottery than in the low probability state. In the high probability state, the possibility of winning a jackpot lottery is higher than in the low probability state, making it an advantageous game state for the player. The high probability state is a so-called "probability variable state (probability variable state)". In this way, there are a low probability state and a high probability state in which it is easier to win a jackpot lottery than in the low probability state.

[0043] The pachinko game machine 10 has a low base state and a high base state as game states in which the ratio of the number of winning balls to the number of game balls shot is different. The high base state is a game state in which the probability of the game ball entering the second starting hole 29 is higher than in the low base state. The high base state is a so-called "electric support state", and the low base state is a so-called "non-electric support state". In the high base state, the probability of the game ball entering the second starting hole 29 is higher, and the game ball is easier to enter the second starting hole 29, so it is a game state (easy ball entry state, ball entry rate improvement state) that is advantageous for the player. In this way, there are a low base state (non-ball entry rate improvement state) and a high base state (ball entry rate improvement state) in which the ball entry rate of the game ball entering the second starting hole 29 is higher (it is easier to enter) than in the low base state.

[0044] For example, the high base state can be realized by performing one of the three controls described below, which are arbitrarily selected, or by combining a plurality of controls. The first control is a normal symbol variation time shortening control that shortens the variation time of the normal game compared to that in the low base state. The second control is a normal symbol probability variation control that varies the probability of winning the normal symbol winning lottery (normal winning probability) to a higher probability than that in the low base state. The third control is an opening time extension control that lengthens the total opening time of the normal variable member 30 in one normal winning game compared to that in the low base state. Note that, as the opening time extension control, at least one of the control that increases the number of openings of the normal variable member 30 in one normal winning game compared to that in the low base state and the control that lengthens the opening time of one normal variable member 30 in a normal winning game compared to that in the low base state may be performed. In this embodiment, in the high base state, the first and second controls are not performed, and the third control is performed, making it easier for the game ball to enter the second starting hole 29 than in the low base state, but this is not limited to the above, and for example, at least one control selected arbitrarily may be performed.

[0045] In this embodiment, the normal hit probability in the low base state exceeds 0. Therefore, the normal variable member 30 can be operated to the permissible state in the low base state. The normal hit probability in the low base state may be 0. In this case, the normal variable member 30 is not operated to the permissible state in the low base state. In other words, the low base state is a state in which it is more difficult for a game ball to enter the second starting hole 29 or in which a game ball does not enter the second starting hole 29 compared to the high base state.

[0046] The high base state may be realized by combining the fourth control described below. The fourth control is a special symbol fluctuation time shortening control that shortens the fluctuation time (for example, average fluctuation time) of the special game compared to the low base state. When the special symbol fluctuation time shortening control is performed, the high base state becomes a so-called "fluctuation time shortening state" for the special symbol. In contrast, the low base state becomes a so-called "non-fluctuation time shortening state" for the special symbol.

[0047] In addition, in this embodiment, the high base state includes a first high base state and a second high base state, which have different conditions to be controlled. The first high base state as the first ball entry rate improvement state is a game state controlled based on the establishment of a first condition among the conditions to be controlled to the high base state. The first condition in this embodiment is a condition that is established after the end of a jackpot game. The second high base state as the second ball entry rate improvement state is a game state controlled based on the establishment of a second condition different from the first condition among the conditions to be controlled to the high base state. The second condition in this embodiment is a condition that is established when a special number of times (598 times in this embodiment) of special games are executed without a jackpot after being controlled to a low probability state. In other words, the high base state is a game state that may be controlled based on the establishment of the first condition or the establishment of the second condition, and is a game state that is controlled based on the establishment of at least the first and second conditions.

[0048] In this embodiment, the opening manner of the normal variable member 30 in the first high base state and the second high base state differs in the normal winning game, and the degree of ball entry into the second starting hole 29 differs, but this is not limited thereto, and for example, the opening manner of the normal variable member 30 may be the same. Hereinafter, the first high base state and the second high base state may be collectively referred to as the high base state.

[0049] Next, a big win in the pachinko gaming machine 10 will be described. The pachinko game machine 10 of this embodiment has a plurality of types of jackpot symbols as special jackpot symbols. A type of jackpot is determined for each of the plurality of types of jackpot symbols. A type of jackpot game is determined for each of the plurality of types of jackpot symbols (types of jackpots).

[0050] In the jackpot game, a predetermined effect is first performed for a predetermined opening time. In this embodiment, an opening effect is performed as the predetermined effect to notify the start of the jackpot game. In the jackpot game, after the opening time has elapsed, multiple rounds of play are performed to open the jackpot opening 31. The number of rounds of play is limited to a predetermined number.

[0051] One round of play ends when a first end condition is met in which a predetermined upper limit number ("10" in this embodiment) of game balls enter the big prize opening 31, or when a second end condition is met in which a predetermined upper limit time has elapsed. That is, the end conditions for ending each of the multiple rounds of play include a first end condition in which the number of game balls entering the big prize opening 31 becomes the upper limit number, and a second end condition in which the number of game balls entering the big prize opening 31 does not become the upper limit number and a predetermined upper limit time has elapsed. In the round play, the big prize opening 31 is opened in a predetermined opening mode, and more specifically, it takes an open state when the round play starts and takes a closed state when the round play ends. In the round play, a round performance is performed. In this way, the special variable member 32 operates so that the big prize opening 31 can be in an open state in each of the multiple round games, and when the start condition for starting each round game is met, the big prize opening 31 is in an open state, and when the end condition for ending each round game is met, the big prize opening 31 is in a closed state. Then, in the big prize game, when the final round game is ended, a predetermined performance is performed for a predetermined ending time. In this embodiment, as the predetermined performance, an ending performance is performed to notify the end of the big prize game. The big prize game ends as the ending time passes.

[0052] Next, a specific big win in the pachinko gaming machine 10 will be described. As shown in FIG. 2, in this embodiment, of the 100 types of jackpot symbols displayed in the first special symbol display section 22a as the game result of the first special game, 100 types of jackpot symbols are classified as symbols ZA. In addition, of the 100 types of jackpot symbols displayed in the second special symbol display section 22b as the game result of the second special game, 25 types of jackpot symbols are classified as symbols Za, 30 types of jackpot symbols are classified as symbols Zb, and 45 types of jackpot symbols are classified as symbols Zc. Thus, in this embodiment, there is one type of jackpot in the first special game, and there are three types of jackpots in the second special game, but this is not limited to this. Hereinafter, the types of jackpots will be expressed as jackpots based on symbols ZA, Za to Zc, using the types of jackpot symbols. In addition, the types of jackpot games awarded based on the types of jackpots are expressed as jackpot games based on the symbols ZA, Za to Zc using the types of jackpot symbols.

[0053] For a jackpot game based on the symbol ZA, the upper limit number of rounds is set to 5 times. For a jackpot game based on the symbol Za, the upper limit number of rounds is set to 10 times. For a jackpot game based on the symbol Zb, the upper limit number of rounds is set to 7 times, which is less than 10 times. For a jackpot game based on the symbol Zc, the upper limit number of rounds is set to 4 times, which is less than 7 times. In this embodiment, the upper limit time for rounds is set to 25 seconds for each jackpot game.

[0054] In this embodiment, for each of the multiple rounds of play, an inter-round interval time (1.5 seconds in this embodiment) is set (specified) after the end of the round of play, and when the inter-round interval time has elapsed, the next round of play will begin or the ending time will begin.

[0055] In addition, in this embodiment, the same opening time (14 seconds in this embodiment) is set for all types of jackpot games, but this is not limited to this, and for example, different opening times may be set depending on the type of jackpot game. In addition, in this embodiment, 11 seconds is set as the ending time, but this is not limited to this, and for example, different ending times may be set depending on the type of jackpot game.

[0056] As shown in FIG. 3, for each big win game, distribution control information indicating the control contents of the distribution member 38 is set. In this embodiment, the multiple round games include an operating round game in which the distribution member 38 is operated from the second distribution state to the first distribution state and then from the first distribution state to the second distribution state, and the first round game is set as the operating round game. Therefore, when the operating round game is started, the distribution member 38 is operated from the second distribution state to the first distribution state and then from the first distribution state to the second distribution state based on the distribution control information set for the type of big win. In a non-operating round game that is not an operating round game, the distribution member 38 is not operated from the second distribution state to the first distribution state and maintains the second distribution state. In this way, the multiple round games include an operating round game in which the distribution member 38 can be operated to the first distribution state and a non-operating round game in which the distribution member 38 is not operated to the first distribution state.

[0057] The control content (distribution control) of the distribution member 38 includes short distribution control in which the time that the distribution member 38 is in the first distribution state is short, and long distribution control in which the time that the distribution member 38 is in the first distribution state is long. In other words, the control content of the distribution member 38 includes a plurality of types of distribution control that operate the distribution member 38 so that the time that the distribution member 38 is in the first distribution state differs.

[0058] In addition, as the distribution control information, the start conditions of each distribution control are determined so as to correspond to each type of jackpot. Specifically, the start conditions of each distribution control are established when the number of game balls detected by the special winning sensor SE3 in the operating round game reaches a specified number. In detail, the start conditions of the short distribution control are established when the number of game balls detected by the special winning sensor SE3 in the operating round game reaches "1" in the same way in all types of jackpot games. The start conditions of the long distribution control are established when the number of game balls detected by the special winning sensor SE3 in the operating round game reaches "2" in the jackpot game based on the symbols Za to Zc. On the other hand, the start conditions of the long distribution control are not established in the operating round game in the jackpot game based on the symbol ZA.

[0059] In addition, the distribution control information defines the end conditions of each distribution control. The end condition of the short distribution control is established when 0.028 s has elapsed since the start condition was established, or when the operating round game ends before 0.028 s has elapsed since the start condition was established. In other words, the short distribution control is a distribution control that operates so that the distribution member 38 takes the second distribution state when the end condition of the round game is not established before a predetermined time has elapsed after the distribution member 38 takes the first distribution state. In addition, the short distribution control is a distribution control that operates so that the distribution member 38 takes the second distribution state when the end condition of the round game is established before a predetermined time has elapsed after the distribution member 38 takes the first distribution state.

[0060] The end condition of the long distribution control is established when a predetermined time (predetermined time, 1.4 s in this embodiment) has elapsed since the end of the operating round game, regardless of the time that has elapsed since the start condition was established. In this embodiment, the predetermined time is set to be a sufficient time from when the game ball that entered the large prize opening 31 enters the large prize opening 31 (when it is detected by the special prize sensor SE3) until it reaches the distribution member 38. In this embodiment, 1.5 s is specified as the interval time between rounds, and 1.4 s is specified as the end condition of the long distribution control, so that a time shorter than the interval time between rounds is specified as the end condition of the long distribution control. In other words, the long distribution control is a distribution control in which the distribution member 38 operates to take the second distribution state when a predetermined time has elapsed since the end condition of the round game was established when the distribution member 38 was in the first distribution state.

[0061] In this embodiment, the end condition of the short distribution control is set to a time shorter than the time from when the game ball is detected by the special winning sensor SE3 until the game ball reaches the distribution member 38. In addition, the sum of the time set as the end condition of the short distribution control and the time from when the distribution member 38 is operated to take the second distribution state from the first distribution state is shorter than the time from when the game ball is detected by the special winning sensor SE3 until the game ball reaches the distribution member 38. In this way, when the game ball is detected by the special winning sensor SE3 and the start condition of the short distribution control is established, the distribution member 38 operates from the second distribution state to the first distribution state, but the end condition of the short distribution control is established before the game ball reaches the distribution member 38, and the distribution member 38 operates from the first distribution state to the second distribution state. In other words, the short distribution control is a distribution control in which the distribution member 38 operates to take the first distribution state when the number of game balls that have entered the large winning port 31 in each operating round game becomes "1", and the distribution member 38 operates to take the second distribution state by the time the game ball reaches the distribution member 38. For this reason, it can be said that the short distribution control is a distribution control that makes it difficult to distribute game balls to the special passing area 36.

[0062] Furthermore, in this embodiment, the time from when the special winning sensor SE3 detects a gaming ball to when the distribution member 38 is operated to change from the second distribution state to the first distribution state is shorter than the time from when the special winning sensor SE3 detects a gaming ball to when the gaming ball reaches the distribution member 38. In this way, when the special winning sensor SE3 detects a gaming ball and the start condition of the long distribution control is established, the distribution member 38 will operate from the second distribution state to the first distribution state by the time the gaming ball reaches the distribution member 38.

[0063] In addition, in the jackpot game based on the symbols Za to Zc, the first round game is performed with short distribution control and long distribution control. In the jackpot game based on the symbol ZA, the first round game is performed with short distribution control, but long distribution control is not performed. Therefore, in the jackpot game based on the symbols Za to Zc, at least the operating round game that allows the game ball to pass through the special passing area 36 is performed, while in the jackpot game based on the symbol ZA, the operating round game that allows the game ball to pass through the special passing area 36 is not performed.

[0064] In this way, the operating round game includes a first operating round game in which the distribution member 38 can be operated to take the first distribution state based on the short distribution control, but the distribution member 38 cannot be operated to take the first distribution state based on the long distribution control. Also, the operating round game includes a second operating round game in which the distribution member 38 can be operated to take the first distribution state based on the short distribution control, and the distribution member 38 can be operated to take the first distribution state based on the long distribution control. The first operating round game is a round game in which the game ball that entered the big prize opening 31 is less likely to pass through the special passing area 36 than the second operating round game. In other words, the jackpot based on ZA is less likely to be controlled to a high probability state after the jackpot game ends than the jackpots based on Za to Zc.

[0065] As shown in Fig. 2, if the game ball passes through the special passing area 36 during a jackpot game, a high probability state is granted as the game state after the end of the jackpot game until the specified number of special games (100 times in this embodiment) are completed. Moreover, this specified number is the same regardless of the type of jackpot determined. On the other hand, if the game ball does not pass through the special passing area 36 during a jackpot game, a low probability state is granted instead of a high probability state as the game state after the end of the jackpot game.

[0066] As shown in FIG. 4, the first high base state is a game state that is controlled with the end of a jackpot game as a trigger. On the other hand, the second high base state is a game state that is controlled with the execution of a special game a special number of times without a jackpot after the control of the low probability state. In this way, even in the high base state in which a game ball is more likely to enter the second starting hole 29 than in the low base state, the trigger (condition) for control is different. In addition, the special number of times, which is the number of times the special game is executed from the control of the low probability state to the control of the second high base state, is a number greater than the specified number of times that can be controlled to the high probability state after the end of a jackpot game, and is a number greater than the first upper limit number of times (100 times or 597 times) that can be controlled to the first high base state after the control of the low probability state after the end of a jackpot game.

[0067] In addition, in this embodiment, the first high base state is a game state that is controlled to continue until a first upper limit number of times (in this embodiment, any one of 100, 597, and 697 times) of a special game is executed without a jackpot. There are multiple types of upper limit numbers for this first upper limit number, and the first upper limit number is a number corresponding to the type of jackpot, the game state when the jackpot lottery is won, and the game state controlled after the jackpot game ends. On the other hand, the second high base state is a game state that is controlled to continue until a second upper limit number of times (759 times in this embodiment) of a special game is executed without a jackpot. In addition, in this embodiment, there is one type of upper limit number for this second upper limit number, and the second upper limit number is the same number of times when the game is controlled to a low probability state and when the game is controlled to a high probability state after the jackpot game ends. The second upper limit number is a number larger than the first upper limit number and a number larger than the special number. In addition, the second upper limit number of times is a number greater than the reciprocal (approximately 320) of the winning probability of the jackpot lottery in a low probability state, and it can be said that the possibility of winning the jackpot lottery is relatively high even in a low probability state.

[0068] Specifically, as shown in FIG. 2, when the jackpot lottery is won and a jackpot based on the Za pattern is determined, the first upper limit number of times is 100 times both when the state is controlled to the high probability state and when the state is controlled to the low probability state after the jackpot game ends. In this way, when the jackpot lottery is won and a jackpot based on the Za pattern is determined, the first upper limit number of times is the same as the specified number of times controlled to the high probability state. Also, when the jackpot lottery is won in the low base state and a jackpot based on the Za pattern is determined, the first upper limit number of times is 100 times when the state is controlled to the low probability state after the jackpot game ends.

[0069] On the other hand, if the jackpot lottery is won in the high base state and a jackpot based on the Za pattern is determined, when the jackpot game is controlled to the low probability state after the jackpot game ends, the first upper limit number of times becomes 597 times, which is greater than 100 times. Also, if the jackpot lottery is won in the high base state and a jackpot based on the Za pattern is determined, when the jackpot game is controlled to the high probability state after the jackpot game ends, the first upper limit number of times becomes 697 times, which is greater than 100 times. Note that these 597 times and 697 times are greater than the reciprocal (approximately 320) of the probability of winning the jackpot lottery in the low probability state, and it can be said that the possibility of winning the jackpot lottery is relatively high even in the low probability state.

[0070] The high base state is controlled when a special game is executed a special number of times after the end of a jackpot game or after the control of the low probability state, so that it is highly likely to be controlled when consecutive jackpots are won (so-called "consecutive wins") or when the game is controlled to a low probability state for a certain period of time (so-called "stuck state"). In addition, in a jackpot game based on the symbol ZA, since it is difficult for a game ball to pass through the special passing area 36, ​​it is highly likely to be controlled to a low probability state after the end of the jackpot game. On the other hand, in a jackpot game based on the symbols Za to Zc, since it is easy for a game ball to pass through the special passing area 36, ​​it is highly likely to be controlled to a high probability state after the end of the jackpot game. In particular, among the jackpot games based on the symbols Za to Zc, the jackpot game based on the symbol Za has a long total opening time of the special variable member 32 in one jackpot game, and can be said to be the most advantageous jackpot game. For this reason, if the jackpot lottery is won in a high base state and a jackpot based on the Za pattern is determined, the first upper limit number of times will be greater than in other cases. For this reason, if a jackpot based on the Za pattern is determined in a high base state, the first upper limit number of times will be greater than in other cases.

[0071] In this way, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on the Za symbol occurs in the high base state and when it is not. Also, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on the Za symbol occurs in the high base state and when it is controlled to a low probability state and when it is controlled to a high probability state.

[0072] In particular, when a jackpot based on the Za symbol is hit in the high base state, if the jackpot is controlled to the high probability state and the first high base state after the jackpot game ends, the 1st to 697th special games are controlled to the first high base state, the 698th special game is controlled to the low base state, and the 699th to 1458th special games are controlled to the second high base state. When a jackpot based on the Za symbol is hit in the high base state, if the jackpot is controlled to the low probability state and the first high base state after the jackpot game ends, the 1st to 597th special games are controlled to the first high base state, the 598th special game is controlled to the low base state, and the 599th to 1358th special games are controlled to the second high base state. In this way, when a jackpot based on the Za symbol is hit in the high base state, if the jackpot is controlled to the first high base state after the jackpot game ends, the number of times the special game is executed from the low base state to the second high base state is one. On the other hand, in other cases, it will be 498 or 598 times.

[0073] In other words, when the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times that the special game is executed from the control to the low base state to the control to the second high base state is smaller when a jackpot based on the symbol Za occurs in the high base state than otherwise. In particular, when a jackpot based on the symbol Za occurs in the high base state and the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times that the special game is executed from the control to the low base state to the control to the second high base state is smaller than the first upper limit number of times, and in particular smaller than the reserved upper limit number of each special game.

[0074] In this embodiment, when comparing the total opening time of the special variable member 32 during one jackpot game, the possibility of being controlled to a high probability state after the jackpot game ends, and the number of times the special game is executed in which the special game is controlled to a high base state after the jackpot game ends, it can be said that the second special game is a more advantageous special game for the player than the first special game.

[0075] In this embodiment, the first special game does not have a jackpot where the game ball is likely to pass through the special passing area 36, ​​but the second special game has a jackpot where the game ball is likely to pass through the special passing area 36. For this reason, in this embodiment, the first special game is won in a low base state, and the second special game is played during the 100 special games controlled to the first high base state after the jackpot game is finished, and the jackpot is won based on the symbols Za to Zc, which is advantageous for the game progress. In particular, in this embodiment, when the second special game is played and the jackpot is won based on the symbols Za, the game progresses advantageously for the player, even though it spans one special game after the jackpot game is finished, and the game progresses advantageously for the player.

[0076] In this embodiment, the jackpot based on the symbol ZA corresponds to the first jackpot, and the jackpot based on the symbol Za corresponds to the specific jackpot and the second jackpot. In this embodiment, when a jackpot based on the symbol Za occurs in a high base state, the first condition that is established after the jackpot game based on the symbol Za ends corresponds to the first special condition, and when a jackpot based on the symbol Za occurs in a low base state, the first condition that is established after the jackpot game based on the symbol Za ends corresponds to the second special condition. In this embodiment, the second condition corresponds to the third special condition.

[0077] In this embodiment, when a jackpot based on the symbol ZA is hit, the first condition that is established after the jackpot game based on the symbol ZA is completed corresponds to the first specific condition, and when a jackpot based on the symbol Za is hit in the high base state, the first condition that is established after the jackpot game based on the symbol Za is completed corresponds to the second specific condition. In this embodiment, the second condition corresponds to the third specific condition.

[0078] In this embodiment, the combination of 597 times and 100 times as the first upper limit number of times corresponds to the combination of the first number and the second number of times. In this embodiment, 759 times as the second upper limit number of times corresponds to the predetermined number of times. In this embodiment, 100 times, which is the upper limit number of times controlled to the high base state, corresponds to the stipulated number of times. In this embodiment, 599 times, which is the number of times the special game is executed from when it is controlled to the low probability state until it is controlled to the second high base state, corresponds to the special number of times.

[0079] As shown in Fig. 5, in this embodiment, the winning probability of the normal winning lottery (normal winning probability) is set to the same probability (65535 / 65536) in all base states. Thus, in this embodiment, the normal winning lottery is a lottery with the same winning probability in the low base state, the first high base state, and the second high base state, but is not limited to this, and may be a lottery with different winning probabilities in at least one of the low base state, the first high base state, and the second high base state.

[0080] The fluctuation time of the normal game is the same (200 ms) in the low base state, the first high base state, and the second high base state, but is not limited to this, and may be different in at least one of the low base state, the first high base state, and the second high base state, or may be the same time but with different determination probabilities. In addition, the fluctuation interval time of the normal game is also the same (500 ms) in the low base state, the first high base state, and the second high base state.

[0081] There are three types of normal winning patterns FZA to FZC that are displayed in the normal pattern display section 22e as the game result of the normal game, and each of the three types of patterns FZA to FZC is determined with the same probability (1 / 3), but this is not limited to the above, and for example, at least any of the patterns may be determined with a different probability, and there may be one type, two types, or four or more types of patterns.

[0082] As the opening mode of the normal variable member 30 in one normal winning game, in the low base state, it is controlled to the open state with an upper limit of 32 ms in all normal winning games, while in the second high base state, it is controlled to the open state with an upper limit of 5400 ms in all normal winning games. Also, as the opening mode of the normal variable member 30 in one normal winning game, in the first high base state, in a normal winning game based on the pattern FZA, it is controlled to the open state for 3000 ms, controlled to the closed state for 1000 ms, and controlled to the open state for 2000 ms until the end condition is established. In a normal winning game based on the pattern FZB, it is controlled to the open state for 2000 ms, controlled to the closed state for 1000 ms, and controlled to the open state for 3000 ms until the end condition is established. In a normal winning game based on the FZC pattern, until the end condition is met, the reel is controlled to the open state for 2500 ms, the closed state for 1000 ms, and the open state for 2500 ms.

[0083] Thus, in the opening mode of the normal variable member 30, the total upper limit opening time during which the second starting hole 29 can be in an open state in one normal winning game is longer in the first high base state and the second high base state than in the low base state. In addition, as the opening mode of the normal variable member 30, there are multiple types of opening modes in the first high base state, while there is only one type of opening mode in the second high base state. And, the multiple types of opening modes in the first high base state are different from the one type of opening mode in the second high base state in that the upper limit number of times the normal variable member 30 can be in an open state in one normal winning game and the total upper limit opening time during which the second starting hole 29 can be in an open state in one normal winning game are different. In this embodiment, as the opening mode of the normal variable member 30, any of the multiple types of opening modes in the first high base state corresponds to the first opening mode and the second opening mode.

[0084] In addition, the first high base state and the second high base state have different total upper limit open times during which the second start port 29 can be in an open state in one normal hit game, and in the second high base state, the total upper limit open times during which the second start port 29 can be in an open state in one normal hit game are longer than in the first high base state. In addition, the normal hit game granted in the first high base state and the normal hit game granted in the second high base state have different upper limit open times during which the normal variable member 30 can be in an open state in one normal hit game.

[0085] In the multiple types of opening modes in the first high base state, the upper limit number of times that the normal variable member 30 can be in the open state in one normal winning game is multiple. In addition, the multiple types of opening modes in the first high base state have the same total upper limit opening time that the second start port 29 can be in the open state in one normal winning game, the upper limit number of times that the normal variable member 30 can be in the open state in one normal winning game, and the same closed time that the normal variable member 30 can be in the closed state in one normal winning game. On the other hand, the multiple types of opening modes in the first high base state have different upper limit opening times that the second start port 29 can be in the open state once.

[0086] In addition, the upper limit control time for normal winning games is the same for all types of normal winning games in the first high base state (6000 ms), while it is the same for all types of normal winning games in the second high base state (5400 ms). In other words, the upper limit control time for normal winning games is shorter in the second high base state than in the first high base state. As a result, in the second high base state, the total upper limit opening time during which the second start hole 29 can be in an open state in one normal winning game is shorter than in the first high base state, but the normal winning game is consumed faster. In addition, in the first high base state, there are multiple types of opening modes of the normal variable member 30 compared to the second high base state, and it is possible to make it more difficult to adjust the launch timing of the game ball so as to make it easier to enter the second start hole 29, thereby improving the technical intervention of the player.

[0087] In this embodiment, the probability of winning is set to 205 / 65536 (approximately 1 / 320) in the low probability state and 995 / 65536 (approximately 1 / 66) in the high probability state. The number of winning balls is set to "2" when the game ball is detected by the first start sensor SE1, "1" when the game ball is detected by the second start sensor SE2, "15" when the game ball is detected by the special winning sensor SE3, and "4" when the game ball is detected by the general winning sensor SE5.

[0088] Next, the electrical configuration of the pachinko gaming machine 10 will be described. As shown in Fig. 6, the pachinko game machine 10 includes a main control board 40 on the back side (rear) of the game board 20. The main control board 40 performs various processes and outputs control signals (control commands) according to the results of the processes.

[0089] The pachinko game machine 10 also includes a sub-control board 41 on the back (rear) of the game board 20. The sub-control board 41 executes a predetermined process based on a control signal input from the main control board 40. For example, the sub-control board 41 executes processes for causing the decorative lamps 17 to emit light, the speaker 18 to produce sound, and the effect display device 27 to produce a display effect.

[0090] The pachinko game machine 10 also includes a power supply unit 60 on the rear side (back) of the game board 20. The power supply unit 60 is a unit that supplies power to the main control board 40 and the sub-control board 41 when a power switch 60a is turned on.

[0091] The pachinko game machine 10 of this embodiment is equipped with a backup function. The backup function is a function that internally stores (backs up) various information related to game control even when the power supply from the external power source is stopped, and restores game control based on the various information stored when the power supply is started. Here, the various information to be backed up includes game information related to the progress of the game. For example, the game information includes information on special games, information on big win games, information on game status, and information on the payout of prize balls. In this embodiment, the main control board 40 and the sub-control board 41 are equipped with the backup function, but the sub-control board 41 does not need to be equipped with the backup function.

[0092] First, the main control board 40 will be described. The main control board 40 includes a main control CPU 40a, a main control ROM 40b, a main control RAM 40c, and an RWM clear switch 40d. The main control CPU 40a executes a main control program to perform various processes.

[0093] The main control ROM 40b stores a main control program, a table used in a predetermined lottery, a judgment value, and the like. The main control ROM 40b also stores a plurality of types of variation patterns. The variation pattern is information capable of identifying a variation time from the start of a special game to the end of the special game. In addition, in this embodiment, the variation pattern is information capable of identifying the presentation content of a presentation game that is performed from the start of a special game to the end of the special game. Note that the variation pattern does not have to be information capable of identifying the presentation content of a presentation game that is performed from the start of a special game to the end of the special game.

[0094] The variation patterns include a jackpot variation pattern, a miss-reach variation pattern, and a miss variation pattern. In this embodiment, the jackpot variation pattern is determined as the performance content of the performance game, which is a performance content that finally derives a jackpot pattern combination through a reach performance, and a performance content that finally derives a jackpot pattern combination without a reach performance. That is, in this embodiment, the jackpot variation pattern can be determined when the jackpot lottery is won, and is either a variation pattern with a reach performance or a variation pattern without a reach performance, but there may be no variation pattern without a reach performance. In the miss-reach variation pattern, the performance content of the performance game is determined as the performance content of the reach performance, which finally derives a miss pattern combination. That is, the miss-reach variation pattern is determined when the jackpot lottery is not won, and is a variation pattern with a reach performance. In the miss variation pattern, the performance content of the performance game is determined as the performance content of the performance game, which is a performance content that finally derives a miss pattern combination without a reach performance. In other words, the failure variation pattern can be determined when the big win lottery is not won, and is a variation pattern that does not involve a reach performance.

[0095] The main control RAM 40c is configured to be capable of storing various information that is rewritten during operation of the pachinko gaming machine 10. The information stored in the main control RAM 40c is, for example, a flag, a counter, and a timer. The main control board 40 is also configured to be capable of generating random numbers. For example, the random numbers may be generated as hardware random numbers or software random numbers.

[0096] The RWM clear switch 40d is configured to be operable to instruct initialization of various types of backed up information. In this embodiment, when the RWM clear switch 40d is in the on state (operated), power is turned on to initialize various types of backed up information.

[0097] The main control CPU 40a and the sensors SE1 to SE6 are connected to each other. The main control CPU 40a is configured to be able to input detection signals that are output when the sensors SE1 to SE6 detect a gaming ball.

[0098] The main control CPU 40a and the actuators A1 to A3 are connected to each other. The main control CPU 40a is configured to be able to control the operations of the actuators A1 to A3. The main control CPU 40a and the information display device 22 are connected to each other. The main control CPU 40a is configured to be able to control the display contents of the information display device 22.

[0099] Next, the sub-control board 41 will be described. The sub-control board 41 and the main control board 40 are connected to each other. The pachinko gaming machine 10 is configured so that a control signal can be output in one direction from the main control board 40 to the sub-control board 41.

[0100] The sub-control board 41 includes a sub-control CPU 41a, a sub-control ROM 41b, and a sub-control RAM 41c. The sub-control CPU 41a executes a sub-control program to perform various processes (e.g., processes related to performance). The sub-control ROM 41b stores the sub-control program, tables used in the lottery, and judgment values. The sub-control ROM 41b stores display performance data related to the display performance in the performance display device 27. The sub-control ROM 41b stores light-emitting performance data related to the light-emitting performance in the decorative lamp 17. The sub-control ROM 41b stores audio performance data related to the audio performance in the speaker 18.

[0101] The sub-control RAM 41c is configured to be capable of storing various information that is appropriately rewritten during operation of the pachinko gaming machine 10. The information stored in the sub-control RAM 41c is, for example, a flag, a counter, and a timer. The sub-control board 41 is also configured to be capable of generating random numbers. For example, the random numbers may be generated as hardware random numbers or software random numbers.

[0102] The sub-control CPU 41a and the performance display device 27 are connected. The sub-control CPU 41a is configured to be able to control the display mode of the performance display device 27. The sub-control CPU 41a and the decorative lamp 17 are connected. The sub-control CPU 41a is configured to be able to control the light emission mode of the decorative lamp 17. The sub-control CPU 41a and the speaker 18 are connected. The sub-control CPU 41a is configured to be able to control the output mode of the speaker 18. The sub-control CPU 41a and the operation button 19 are connected. The sub-control CPU 41a is configured to be able to input an operation signal indicating that the operation button 19 has been operated.

[0103] Next, various processes performed in the pachinko gaming machine 10 will be described. First, the special symbol input process performed by the main control CPU 40a will be described. The special symbol input process is performed as an interrupt process.

[0104] In the special symbol input process, the main control CPU 40a determines whether or not a gaming ball has entered the first start hole 28 based on whether or not a detection signal has been input from the first start sensor SE1. When a game ball enters the first start hole 28, the main control CPU 40a judges whether the first special reserved number stored in the main control RAM 40c is less than the upper limit number ("4" in this embodiment). When the first special reserved number is less than the upper limit number, the main control CPU 40a updates the first special reserved number stored in the main control RAM 40c by adding "1". This establishes the reservation condition (first reservation condition) of the first special game. That is, the entry of a game ball into the first start hole 28 is a trigger to reserve the execution of the first special game. In this embodiment, the main control CPU 40a that reserves the execution of the first special game (special game) up to a predetermined upper limit number (reservation upper limit number) in response to the entry of a game ball into the first start hole 28 corresponds to the reservation means. In this process, the main control CPU 40a controls the information display device 22 to display the updated first special reserved number. In addition, the main control CPU 40a sets information capable of identifying the updated first special reserved number (hereinafter referred to as the first reserved number command) in the output buffer. The information (control command) set in the output buffer is output to the sub-control board 41 in the next or subsequent interrupt processing.

[0105] Next, the main control CPU 40a acquires random numbers generated in the main control board 40, and stores random number information based on the acquired random numbers in the main control RAM 40c. For example, the random numbers are random numbers used in a jackpot lottery, random numbers used to determine a jackpot symbol, and random numbers used to determine a variation pattern. In this process, the main control CPU 40a stores the random number information so that it is possible to identify that it is random number information for the first special game and the storage order of the random number information. In this embodiment, by storing the random number information for the first special game in the main control RAM 40c, the execution of the first special game can be suspended until the execution condition of the first special game is established. In this way, the execution of the first special game (special game) can be suspended when a game ball enters the first starting hole 28. The random number information may be the acquired random number itself, or may be information obtained by processing the random number by a predetermined method.

[0106] When no game ball has entered the first start hole 28, when the number of first special reserved balls is not less than the upper limit number, and when random number information for the first special game is stored in the main control RAM 40c, the main control CPU 40a judges whether or not a game ball has entered the second start hole 29 based on whether or not a detection signal has been input from the second start sensor SE2. When no game ball has entered the second start hole 29, the main control CPU 40a ends the special symbol input process.

[0107] When a game ball enters the second start hole 29, the main control CPU 40a judges whether the second special reserved number stored in the main control RAM 40c is less than the upper limit number ("4" in this embodiment). When the second special reserved number is not less than the upper limit number, the main control CPU 40a ends the special symbol input process. When the second special reserved number is less than the upper limit number, the main control CPU 40a updates the second special reserved number stored in the main control RAM 40c by adding "1". This establishes the reservation condition (second reservation condition) of the second special game. That is, the entry of a game ball into the second start hole 29 is a trigger to reserve the execution of the second special game. In this embodiment, the main control CPU 40a that reserves the execution of the second special game (special game) up to a predetermined upper limit number (reservation upper limit number) in response to the entry of a game ball into the second start hole 29 corresponds to the reservation means. In this process, the main control CPU 40a controls the information display device 22 to display the updated second special reserved number. In addition, the main control CPU 40a sets information capable of identifying the updated second special reserved number (hereinafter, referred to as a second reserved number command) in the output buffer.

[0108] Next, the main control CPU 40a acquires random numbers generated within the main control board 40, and stores random number information based on the acquired random numbers in the main control RAM 40c. In this process, the main control CPU 40a stores the random number information so that it is possible to identify that the random number information is for the second special game, and the storage order of the random number information. In this embodiment, by storing the random number information for the second special game in the main control RAM 40c, the execution of the second special game can be suspended until the execution condition of the second special game is satisfied. In this way, the execution of the second special game (special game) can be suspended when a game ball enters the second starting hole 29.

[0109] Next, the special symbol start process performed by the main control CPU 40a will be described. The special symbol start process is performed as an interrupt process. In the special symbol start process, the main control CPU 40a judges whether the execution condition of the special game is satisfied. The main control CPU 40a judges positively when neither a jackpot game nor a special game is being played, and judges negatively when a jackpot game or a special game is being played. If the execution condition of the special game is not satisfied, the main control CPU 40a ends the special symbol start process.

[0110] On the other hand, when the execution condition of the special game is established, the main control CPU40a judges whether the second special reserved number stored in the main control RAM40c is "1" or more. When the second special reserved number is "1" or more, the main control CPU40a performs a predetermined process so that the execution condition of the second special game is established and the second special game is started. On the other hand, when the second special reserved number is not "1" or more, the main control CPU40a judges whether the first special reserved number stored in the main control RAM40c is "1" or more. When the first special reserved number is "1" or more, the main control CPU40a performs a predetermined process so that the execution condition of the first special game is established and the first special game is started. In this way, the main control CPU40a executes the second special game in priority to the first special game. On the other hand, when the first special reserved number is not "1" or more, the main control CPU40a ends the special symbol start process. In addition, when the special game or big win game is not being played and each special reserved number is "0", the main control CPU 40a will control the game to a standby state in which the special game and big win game are not being played.

[0111] When starting the first special game, the main control CPU40a updates the first special reserved number stored in the main control RAM40c by subtracting "1". In this process, the main control CPU40a controls the information display device 22 so that the updated first special reserved number is displayed. Next, the main control CPU40a reads out the first stored random number information of the random number information for the first special game from the main control RAM40c. After reading out the first stored random number information, the main control CPU40a erases the random number information from the main control RAM40c.

[0112] Next, the main control CPU 40a judges whether or not a jackpot will be won based on the read random number information and the jackpot judgment value stored in the main control ROM 40b. The judgment of whether or not a jackpot will be won is, for example, judged by whether or not the value of the random number specified from the random number information matches the jackpot judgment value corresponding to the current probability state. The judgment of whether or not a jackpot will be won may be judged by whether or not the value obtained by adding the value of the random number specified from the random number information and the jackpot judgment value exceeds a predetermined value. In this way, the main control CPU 40a performs a jackpot lottery according to the entry of the game ball into the first starting hole 28, and judges whether or not a jackpot will be won. In this embodiment, the main control CPU 40a that executes such processing corresponds to a jackpot lottery means (jackpot judgment means).

[0113] When a jackpot is won, the main control CPU40a determines the jackpot symbol derived in the first special game and the variation pattern of the first special game. For example, the main control CPU40a determines the jackpot symbol derived in the first special game and the variation pattern of the first special game by lottery using the read random number information for the first special game. In this embodiment, the main control CPU40a that executes such processing corresponds to the jackpot type determination means. In addition, in this embodiment, the main control CPU40a that determines the variation pattern based on a predetermined determination condition corresponds to the variation pattern determination means. When the jackpot symbol derived in the first special game is determined, the main control CPU40a sets information (hereinafter referred to as a pattern command) that can specify the determined jackpot symbol in the output buffer. When the variation pattern of the first special game is determined, the main control CPU40a sets information (hereinafter referred to as a game start command) that can specify the determined variation pattern and instructs the start of a performance game based on the variation pattern in the output buffer. After setting the symbol command and the first game start command in the output buffer, the main control CPU 40a ends the special symbol start process.

[0114] On the other hand, in the case of a loss that does not win a jackpot, the main control CPU40a determines the loss symbol derived in the first special game and the variation pattern of the first special game. For example, the main control CPU40a determines the loss symbol derived in the first special game and the variation pattern of the first special game by a lottery using the read random number information for the first special game. In this embodiment, the main control CPU40a that determines the variation pattern based on a predetermined determination condition corresponds to the variation pattern determination means. When the loss symbol derived in the first special game is determined, the main control CPU40a sets information (hereinafter, referred to as a pattern command) capable of identifying the determined loss symbol in the output buffer. When the variation pattern of the first special game is determined, the main control CPU40a sets a game start command that can identify the determined variation pattern and is based on the variation pattern in the output buffer. After setting the symbol command and the first game start command in the output buffer, the main control CPU40a ends the special symbol start process.

[0115] When the second special game is started, the main control CPU40a performs the same control as that when the first special game is started. That is, the main control CPU40a performs subtraction of the second special reserved number, jackpot lottery (jackpot judgment), decision of jackpot or non-jackpot symbols based on the result of the jackpot lottery, decision of the variation pattern based on the result of the jackpot lottery, and setting of the symbol command and the game start command. Thus, in this embodiment, the main control CPU40a performs a jackpot lottery according to the entry of a game ball into the second start hole 29, and judges whether or not a jackpot will be obtained. In this embodiment, the main control CPU40a that executes such processing corresponds to a jackpot lottery means (jackpot judgment means). Also, in this embodiment, it can be said that the jackpot lottery includes a jackpot lottery for the first special game performed according to the entry of a game ball into the first start hole 28, and a jackpot lottery for the second special game performed according to the entry of a game ball into the second start hole 29. After that, the main control CPU 40a ends the special symbol start process.

[0116] Then, when the special symbol start process is ended, the main control CPU 40a executes a special game by performing a process other than the special symbol start process. Specifically, the main control CPU 40a controls the information display device 22 so that the special game is started. The main control CPU 40a measures a change time set in the change pattern determined in the special symbol start process. Then, the main control CPU 40a controls the information display device 22 so that the special symbol determined in the special symbol start process is derived when the change time set in the change pattern has elapsed. In this way, based on the result of the big win lottery, the first special symbol display unit 22a of the information display device 22 can execute the first special game as a special game in response to the entry of a game ball into the first start hole 28, and the second special symbol display unit 22b of the information display device 22 can execute the second special game as a special game in response to the entry of a game ball into the second start hole 29. In addition, when the change time set in the change pattern determined in the special pattern start processing has elapsed, the main control CPU 40a instructs the stop of the change in the performance pattern, and sets information (hereinafter referred to as the game end command) for deriving a pattern combination based on the performance pattern in the output buffer.

[0117] By executing such a special symbol start process, when the random number value related to the special game is stored, the main control CPU 40a judges whether the special game will be a jackpot in the order of the earliest total acquisition order, regardless of whether the random number value is related to the first special game or the second special game, and executes the special game. In other words, the special game is executed in the order in which the game balls enter the first start hole 28 and the second start hole 29.

[0118] Next, the big win process performed by the main control CPU 40a will be described. In the jackpot process, the main control CPU 40a performs control to award a jackpot game based on the jackpot symbol (type of jackpot) determined in the special symbol start process. That is, the main control CPU 40a awards a jackpot game by executing the jackpot process.

[0119] When the special game of the big win is over, the main control CPU40a first sets information (hereinafter, referred to as an opening command) capable of identifying the start of the opening time in the output buffer. When the opening time has elapsed, the main control CPU40a performs processing for executing a round game. Specifically, the main control CPU40a controls the special actuator A2 so that the big prize opening 31 is opened based on an opening pattern determined by the big win symbol (type of big win), and starts the round game. After starting the round game, when the first end condition or the second end condition is established, the main control CPU40a controls the special actuator A2 so that the big prize opening 31 is closed, and ends the round game. The main control CPU40a repeats such processing for executing the round game until the specified number of round games are completed.

[0120] In addition, the main control CPU 40a sets information capable of identifying the start of a round game (hereinafter referred to as a round command) in the output buffer each time a round game is started. In addition, the main control CPU 40a sets information capable of identifying the end of a round game (hereinafter referred to as a round end command) in the output buffer each time a round game is ended.

[0121] In particular, during an operating round play in which the distribution member 38 is operated from the second distribution state to the first distribution state among multiple rounds of play, the main control CPU 40a controls the distribution actuator A3 based on distribution control information defined for the jackpot pattern (type of jackpot), and controls the operation of the distribution member 38.

[0122] Specifically, the main control CPU 40a counts the number of game balls that have entered the large prize opening 31 in an operating round game based on a detection signal from the special prize sensor SE3. In this embodiment, the main control CPU 40a counts the number of game balls that have entered the large prize opening 31 not only in an operating round game but also in a non-operating round game based on a detection signal from the special prize sensor SE3.

[0123] When the main control CPU 40a judges that the number of game balls entering the large prize opening 31 is the number of balls that satisfies the start condition of the short distribution control by referring to the distribution control information determined for the jackpot pattern (type of jackpot), the start condition of the short distribution control is satisfied and the short distribution control is started. Then, the main control CPU 40a performs the short distribution control until the end condition of the short distribution control is satisfied, and when the end condition of the short distribution control is satisfied, the distribution member 38 is operated from the first distribution state to the second distribution state to end the short distribution control.

[0124] In detail, when any of the types of all the big wins is determined, the start condition of the short distribution control is established when the number of game balls entering the big winning port 31 in each operating round game becomes "1", and the main control CPU 40a operates the distribution member 38 to take the first distribution state based on the short distribution control. Then, the main control CPU 40a counts the elapsed time since the start condition of the short distribution control was established. When a predetermined time (0.028 s in this embodiment) has elapsed or when the end condition of each operating round game is established, the end condition of the short distribution control is established, and the main control CPU 40a operates the distribution member 38 to take the second distribution state.

[0125] When the main control CPU 40a judges that the number of game balls entering the large prize winning port 31 is the number of balls that satisfies the start condition of the long distribution control by referring to the distribution control information determined for the jackpot pattern (type of jackpot), the start condition of the long distribution control is satisfied and the long distribution control is started. Then, the main control CPU 40a performs the long distribution control until the end condition of the long distribution control is satisfied, and when the end condition of the long distribution control is satisfied, the distribution member 38 is operated from the first distribution state to the second distribution state to end the long distribution control.

[0126] In detail, when a jackpot based on the symbols Za to Zc is determined, the start condition of the long distribution control is established when the number of game balls entering the big prize winning port 31 in the first round game as the second operating round game becomes "2", and the main control CPU 40a operates the distribution member 38 to take the first distribution state based on the long distribution control. Note that, when a jackpot based on the symbols ZA is determined, the main control CPU 40a does not perform the long distribution control in the first round game.

[0127] When the game ball passes through the special passing area 36 during a jackpot game, the main control CPU 40a stores information indicating the passing of the game ball into the special passing area 36 in the main control RAM 40c. In addition, when the game ball passes through the special passing area 36 during a jackpot game, the main control CPU 40a sets information capable of identifying the passing of the game ball into the special passing area 36 (hereinafter, referred to as a special passing command) in the output buffer.

[0128] When the final round of play ends, the main control CPU 40a sets information capable of identifying the start of the ending time (hereinafter, referred to as an ending command) in the output buffer. When the ending time has elapsed, the main control CPU 40a ends the big win game.

[0129] Next, the game status processing performed by the main control CPU 40a will be described. The main control CPU 40a sets the main base state flag to a value that can specify that the first high base state is to be controlled for all types of jackpots, with the start of the ending time as a trigger. The main base state flag is a flag assigned to the main control RAM 40c, and is a flag that can specify whether the state is to be controlled to a low base state, a first high base state, or a second high base state.

[0130] The main control CPU 40a also identifies the game state when the jackpot lottery is won, the type of jackpot, and whether the game ball passed through the special passing area 36 during the jackpot game. The main control CPU 40a then identifies the upper limit number of times corresponding to the identified result as the first upper limit number of times controllable to the first high base state, and sets the value that can identify the first upper limit number to the main high base number counter. The main high base number counter is assigned to the main control RAM 40c, and is a counter for counting the number of times the special game that can be controlled to the high base state (first high base state or second high base state) is executed.

[0131] Specifically, when the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the Za pattern, and the game ball has passed through the special passing area 36 during the jackpot game, the main control CPU 40a specifies "697" as the first upper limit number of times. When the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the Za pattern, and the game ball has not passed through the special passing area 36 during the jackpot game, the main control CPU 40a specifies "597" as the first upper limit number of times. In other cases, the main control CPU 40a specifies "100" as the first upper limit number of times.

[0132] In addition, when the main control CPU 40a determines that the game ball has passed through the special passing area 36 during a jackpot game, the main control CPU 40a sets the main probability state flag to a value that can specify that the game is controlled to a high probability state for all types of jackpots. The main probability state flag is assigned to the main control RAM 40c, and is a flag that can specify whether the game is controlled to a low probability state or a high probability state. The main control CPU 40a then sets the main high probability count counter to a specified number of times ("100" in this embodiment) that the game can be controlled to a high probability state. The main high probability count counter is assigned to the main control RAM 40c, and is a counter for counting the number of times that a special game that can be controlled to a high probability state is executed.

[0133] In addition, when the main control CPU 40a determines that the game ball has not passed through the special passing area 36 during the jackpot game, triggered by the input of an ending command, the main control CPU 40a sets a value that can specify control to a low probability state for all types of jackpots to the main probability state flag. Then, the main control CPU 40a sets a value that can specify the number of special times to the main low probability number counter. The main low probability number counter is assigned to the main control RAM 40c, and is a counter for counting the number of times the special game is executed after being controlled to the low probability state.

[0134] Then, the main control CPU 40a subtracts "1" from the main high base count counter, the main high probability count counter, and the main low probability count counter that are assigned to the main control RAM 40c, and that are not set to "0", every time the special game is executed. In this embodiment, the main control CPU 40a subtracts "1" from each of the counters when the special game ends, but the present invention is not limited to this and may subtract "1" from each of the counters when the special game starts, for example.

[0135] In this embodiment, the first upper limit number of times is different between the case where the jackpot lottery is won in the high base state and the jackpot type is determined to be a jackpot based on the Za symbol and the other cases. Also, in this embodiment, the first upper limit number of times is different between the case where the jackpot lottery is won in the high base state and the jackpot type is determined to be a jackpot based on the Za symbol after the jackpot game ends, and the case where the low probability state is controlled and the high probability state is controlled.

[0136] When the main high base count counter is updated from "1" to "0", the main control CPU 40a sets the main base state flag to a value that can specify that the game is controlled to the low base state. When the main high probability count counter is updated from "1" to "0", the main control CPU 40a sets the main probability state flag to a value that can specify that the game is controlled to the low probability state, and sets the main low probability count counter to a value that can specify the special count. In this way, when the main control CPU 40a controls the game to the high probability state after the end of a big win game, it controls the game to the low probability state when a predetermined control condition is established triggered by the execution of a specified number of special games. When the main low probability count counter is updated from "1" to "0", the main control CPU 40a sets the main base state flag to a value that can specify that the game is controlled to the second high base state, and sets the main high base count counter to the second upper limit count.

[0137] In this embodiment, the main control CPU 40a, upon input of an opening command, sets the main base state flag, main probability state flag, main high base number counter, main high probability number counter, and main low probability number counter to "0" and initializes each flag and counter.

[0138] In this way, the main control CPU 40a may control the state to a low probability state after the end of a jackpot game, or may control the state to a high probability state after the end of a jackpot game. In particular, when the game ball passes through the special passing area 36 during a jackpot game, the main control CPU 40a controls the state to a high probability state after the end of a jackpot game, while when the game ball does not pass through the special passing area 36 during a jackpot game, the main control CPU 40a controls the state to a low probability state after the end of a jackpot game. When the main control CPU 40a is controlled to a high probability state after the end of a jackpot game, the main control CPU 40a can control the state to a high probability state until a specified number of special games are executed without winning the jackpot lottery, and controls the state to a low probability state when a specified number of special games are executed and a specified control condition is established.

[0139] In addition, when the main control CPU 40a controls the reel to the first high base state, it continues to control the reel to the first high base state until a special game of the first maximum number of times is played without a jackpot being obtained, and then controls the reel to the low base state when the special game of the first maximum number of times is played.

[0140] In detail, in this embodiment, when the main control CPU 40a has won a jackpot based on the symbol Za in the high base state and has controlled to the high probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 697 special games are executed without winning the jackpot lottery. When the main control CPU 40a has won a jackpot based on the symbol Za in the high base state and has controlled to the low probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 597 special games are executed without winning the jackpot lottery. On the other hand, when the main control CPU 40a has won a jackpot based on the symbols ZA, Zb, Zc, or has won a jackpot based on the symbol Za in the low base state and has controlled to the first high base state, the main control CPU 40a controls to the low base state when 100 special games are executed without winning the jackpot lottery.

[0141] On the other hand, when the main control CPU40a controls the base state to the second high base state, the main control CPU40a continues to control the base state to the second high base state until the special game is executed the second maximum number of times without winning a jackpot, and controls the base state to the low base state when the special game is executed the second maximum number of times. In other words, when the main control CPU40a controls the base state to the second high base state, the main control CPU40a controls the base state to the second high base state until the special game is executed the second maximum number of times (759 times in this embodiment) without winning a jackpot lottery, regardless of the first maximum number of times controlled to the first high base state.

[0142] In addition, after the main control CPU 40a controls the reel to the low base state in response to the special game being played a second maximum number of times without a jackpot in the second high base state, the main control CPU 40a does not control the reel to the high base state in response to the special game being played a predetermined number of times without a jackpot in the low base state.

[0143] In addition, when the main control CPU 40a is controlled to the first high base state after the end of the big win game, it controls the state to either the high probability state or the low probability state, while when the main control CPU 40a is controlled to the second high base state, it controls the state to the low probability state instead of the high probability state. In this embodiment, the main control CPU 40a that controls the game state corresponds to the game state control means.

[0144] When the main control CPU 40a sets a value that can specify control to a low probability state to the main probability state flag, it sets information that can specify a low probability state (hereinafter referred to as a low probability state command) to the output buffer. On the other hand, when the main control CPU 40a sets a value that can specify control to a high probability state to the main probability state flag, it sets information that can specify a high probability state (hereinafter referred to as a high probability state command) to the output buffer.

[0145] When the main control CPU 40a sets the main base state flag to a value that can identify control to the low base state, it sets information that can identify the low base state (hereinafter referred to as a low base state command) in the output buffer. On the other hand, when the main control CPU 40a sets the main base state flag to a value that can identify control to the first high base state, it sets information that can identify the first high base state (hereinafter referred to as a first high base state command) in the output buffer. Also, when the main control CPU 40a sets the main base state flag to a value that can identify control to the second high base state, it sets information that can identify the second high base state (hereinafter referred to as a second high base state command) in the output buffer.

[0146] Next, the normal symbol input process performed by the main control CPU 40a will be described. The normal symbol input process is performed as an interrupt process. In the normal symbol input process, the main control CPU 40a judges whether the game ball has passed (entered) the gate 33 based on whether a detection signal has been input from the gate sensor SE4. If the game ball has not passed the gate 33, the main control CPU 40a ends the normal symbol input process. On the other hand, if the game ball has passed the gate 33, the main control CPU 40a judges whether the normal reserved number stored in the main control RAM 40c is less than the upper limit number ("4" in this embodiment). If the normal reserved number is not less than the upper limit number, the main control CPU 40a ends the normal symbol input process. If the normal reserved number is less than the upper limit number, the main control CPU 40a updates the normal reserved number stored in the main control RAM 40c by adding "1". This establishes the reservation condition for the normal game. In addition, the main control CPU 40a controls the information display device 22 to display the updated normal reserved number.

[0147] Next, the main control CPU 40a acquires random numbers generated in the main control board 40, and stores random number information based on the acquired random numbers in the main control RAM 40c. For example, the random numbers are random numbers used for drawing winning normal symbols, random numbers used for determining winning normal symbols, and random numbers used for determining the variable time of the normal game. In this case, the main control CPU 40a stores the random number information so that it is possible to identify that it is random number information for the normal game, and the storage order of the random number information. In this embodiment, by storing the random number information for the normal game in the main control RAM 40c, the execution of the normal game can be suspended until the execution condition of the normal game is established. After that, the main control CPU 40a ends the normal symbol input process.

[0148] Next, the normal symbol start process performed by the main control CPU 40a will be described. The normal symbol start process is performed as an interrupt process. In the normal symbol start process, the main control CPU 40a judges whether the execution condition of the normal game is satisfied. The main control CPU 40a judges positively when the normal win game is not being played and the normal game is not being played, and judges negatively when the normal win game is being played or the normal game is being played. If the execution condition of the normal game is not satisfied, the main control CPU 40a ends the normal symbol start process.

[0149] On the other hand, when the execution condition of the normal game is established, the main control CPU 40a judges whether the normal reserved number stored in the main control RAM 40c is "1" or more. When the normal reserved number is not "1" or more (when it is zero (0)), the main control CPU 40a ends the normal symbol start process. When the normal reserved number is "1" or more, the main control CPU 40a subtracts "1" from the normal reserved number stored in the main control RAM 40c and updates it. In addition, the main control CPU 40a controls the information display device 22 so that the updated normal reserved number is displayed. Next, the main control CPU 40a reads out the random number information for the normal game that was stored first from the main control RAM 40c. In addition, when the main control CPU 40a reads out the random number information that was stored first, it erases the random number information from the main control RAM 40c.

[0150] Next, the main control CPU 40a judges whether or not a normal win will occur based on the read random number information, the current game state, and the normal win judgment value stored in the main control ROM 40b.

[0151] In addition, in this embodiment, the main control CPU 40a wins a normal win with the same probability when the current game state is a low base state and when the current game state is a high base state, and the normal win lottery can be said to be a lottery that wins with the same probability in the low base state, the first high base state, and the second high base state, but is not limited to this. For example, the normal win lottery may be a lottery that is won with a higher probability in the high base state (the first high base state and the second high base state) than in the low base state. Also, for example, the normal win lottery may be a lottery that is won with a higher probability in the second high base state than in the first high base state, or a lottery that is won with a higher probability in the first high base state than in the second high base state. Any combination of these combinations may be adopted.

[0152] When a normal win is won, the main control CPU40a determines the normal winning symbol to be derived in the normal game and the variable time of the normal game. When the main control CPU40a determines the variable time of the normal game, it sets information capable of identifying the determined variable time (hereinafter, referred to as a normal start command) in the output buffer. The normal start command may be information capable of identifying the result of the lottery for the winning normal symbol. After that, the main control CPU40a ends the normal symbol start process.

[0153] If the normal win is not obtained, the main control CPU 40a determines the normal losing symbol to be derived in the normal game and the variable time of the normal game. When the main control CPU 40a determines the variable time of the normal game, it sets a normal start command capable of specifying the determined variable time in the output buffer. After that, the main control CPU 40a ends the normal symbol start process.

[0154] Then, the main control CPU 40a executes a normal game by performing a process different from the normal symbol start process. Specifically, the main control CPU 40a starts the normal game and controls the information display device 22 so that the normal symbol determined in the normal symbol start process is output when the variable time determined in the normal symbol start process has elapsed.

[0155] Next, the normal winning process performed by the main control CPU 40a will be described. When a normal win is won, the main control CPU40a determines the opening pattern of the second start hole 29 based on the current game state, and controls the normal actuator A1 so that the second start hole 29 is opened based on the determined opening pattern. In particular, when the above-mentioned opening time extension control is adopted, the main control CPU40a determines the opening pattern for the low base in the low base state regardless of the normal winning symbol, and determines the opening pattern for the second high base in the second high base state. On the other hand, in the first high base state, the main control CPU40a determines the opening pattern for the first high base corresponding to the determined normal winning symbol from among the multiple types of opening patterns for the first high base.

[0156] Next, various processes performed by the sub-control CPU 41a will be described. First, the presentation game process performed by the sub-control CPU 41a will be described. The sub-control CPU41a determines a symbol combination to be derived in the performance game based on the game start command and the symbol command. When the special symbol identifiable from the symbol command is a big win symbol, the sub-control CPU41a determines a big win symbol combination by the performance symbol. When the special symbol identifiable from the symbol command is a losing symbol, the sub-control CPU41a determines a losing symbol combination by the performance symbol.

[0157] In addition, when the execution condition of the reach performance is established and the reach performance is executed in the performance game, the sub-control CPU41a determines a losing symbol combination including the reach (for example, "787"). In this embodiment, the execution condition of the reach performance is determined to be that a losing variation pattern with the reach performance is determined. Note that the execution condition of the reach performance may be determined to be that the sub-control CPU41a executes a predetermined reach lottery and wins the reach lottery.

[0158] In addition, the sub-control CPU41a controls the effect display device 27 so that the effect symbols are variably displayed in each column upon input of a game start command. That is, the sub-control CPU41a starts the effect game. After starting the effect game, the sub-control CPU41a temporarily stops and displays the symbol combination of the determined effect symbols when a predetermined timing arrives, and derives the symbol combination of the determined effect symbols upon input of a game end command. The sub-control CPU41a may measure a variation time that can be specified from the variation pattern, regardless of the game end command, and derive the symbol combination upon the passage of the variation time. In this case, the game end command may be omitted.

[0159] Next, the big win effect processing performed by the sub-control CPU 41a will be described. The sub-control CPU41a controls the performance display device 27 so that an opening performance is performed when an opening command is input. The sub-control CPU41a controls the performance display device 27 so that a round performance is performed when a round command is input. Furthermore, the sub-control CPU41a ends the round performance when a round end command is input. The sub-control CPU41a controls the performance display device 27 so that an ending performance is performed when an ending command is input. In this way, the sub-control CPU41a executes the opening performance, round performance, and ending performance as jackpot performance during jackpot play.

[0160] In this embodiment, the sub-control CPU 41a may control at least one of the decorative lamps 17 and the speakers 18 in addition to the performance display device 27 so that various performances are performed.

[0161] Next, the game status processing performed by the sub-control CPU 41a will be described. When the sub-control CPU 41a inputs a low probability state command, it sets the sub-probability state flag to a value that can specify a low probability state, and sets the sub-low probability count counter to a value that can specify a special count. The sub-probability state flag is assigned to the sub-control RAM 41c, and is a flag that can specify whether to control to a low probability state or a high probability state. The sub-low probability count counter is assigned to the sub-control RAM 41c, and is a counter for counting the number of times a special game is executed after being controlled to a low probability state. On the other hand, when the sub-control CPU 41a inputs a high probability state command, it sets the sub-probability state flag to a value that can specify a high probability state, and sets the sub-high probability count counter to a value that can specify a specified count. The sub-high probability count counter is assigned to the sub-control RAM 41c, and is a counter for counting the number of times a special game that can be controlled to a high probability state is executed.

[0162] When the sub-control CPU 41a inputs a low base state command, it sets the sub-base state flag to a value that can specify that the game is in the low base state. The sub-base state flag is assigned to the sub-control RAM 41c, and is a flag that can specify whether the game is to be controlled to the low base state, the first high base state, or the second high base state. When the sub-control CPU 41a inputs a first high base state command, it sets the sub-base state flag to a value that can specify that the game is in the first high base state, and sets the sub-high base count counter to a value that can specify the first upper limit count. The sub-high base count counter is a counter for counting the number of times that a special game that can be controlled to the high base state (the first high base state or the second high base state) is executed. Specifically, the sub-control CPU 41a specifies the game state and the type of the jackpot when the jackpot lottery is won, and specifies whether the game ball has passed through the special passing area 36 during the jackpot game based on the input of the special passing command. Then, when the sub-control CPU41a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Za, and the game ball has passed through the special passing area 36 during the jackpot game, it determines "697" as the first upper limit number of times. When the sub-control CPU41a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Za, and the game ball has not passed through the special passing area 36 during the jackpot game, it determines "597" as the first upper limit number of times. In other cases, the sub-control CPU41a determines "100" as the first upper limit number of times. When the sub-control CPU41a inputs the second high base state command, it sets a value that can identify the second high base state to the sub-base state flag, and sets a value that can identify the second upper limit number of times to the high base number counter.

[0163] Here, the fluctuation pattern and the determination conditions for determining the fluctuation pattern will be described in detail with reference to FIG. As shown in Fig. 7, there are several kinds of fluctuation patterns in the present embodiment, and the fluctuation patterns are selected depending on whether or not the player hits a jackpot. Specifically, the fluctuation patterns HP21, HP22, HP51-HP54, and HP71 are defined as jackpot fluctuation patterns. The fluctuation patterns HP11, HP12, HP41, and HP61 are defined as miss reach fluctuation patterns, and the fluctuation patterns HP01-HP03, HP31-HP35, and HP61 are defined as miss fluctuation patterns.

[0164] As will be described in detail later, in this embodiment, the fluctuation patterns HP01 to HP03, HP11, HP12, HP21, and HP22 are deviation fluctuation patterns that can be determined in a low base state. The fluctuation patterns HP31 to HP35, HP41, HP51 to HP54, HP61, and HP71 are deviation fluctuation patterns that can be determined in a low base state.

[0165] Each fluctuation pattern corresponds to a fluctuation time, and the fluctuation time can be specified from the fluctuation pattern. Specifically, in this embodiment, the fluctuation patterns HP01 to HP03 are deviation fluctuation patterns that can be determined in a low base state. The fluctuation pattern HP02 is a fluctuation pattern that shortens the fluctuation time of the fluctuation pattern HP01. The fluctuation pattern HP03 is a fluctuation pattern that further shortens the fluctuation time of the fluctuation patterns HP01 and HP02. In this embodiment, the fluctuation patterns HP31 to HP35 are deviation fluctuation patterns that can be determined in a high base state. The fluctuation patterns HP33 and HP34 are fluctuation patterns that shorten the fluctuation time of the fluctuation patterns HP31 and HP32. The fluctuation pattern HP35 is a fluctuation pattern that further shortens the fluctuation time of the fluctuation patterns HP31 to HP34. In this way, there are multiple types of deviation fluctuation patterns with different fluctuation times.

[0166] The variation patterns HP11 and HP21 are variation patterns in which a reach is formed in the performance game (during the execution of the special game) and a normal reach (hereinafter, sometimes indicated as "NR") performance is executed. The variation patterns HP12 and HP22 are variation patterns in which a reach is formed in the performance game (during the execution of the special game) and a NR performance is executed, and then a first super reach (hereinafter, sometimes indicated as "SR1") performance is executed. The variation patterns HP41 and HP51 are variation patterns in which a reach is formed in the performance game (during the execution of the special game) and a NR performance is executed, and then a second super reach (hereinafter, sometimes indicated as "SR2") performance is executed. The variation patterns HP52 to HP54 are jackpot variation patterns in which a reach is not formed in the performance game (during the execution of the special game) and a jackpot occurs (indicated as "hit" in the figure). In particular, the fluctuation patterns HP11 and HP21 are fluctuation patterns that execute an NR performance and do not develop into an SR1 performance or an SR2 performance, and are fluctuation patterns with shorter fluctuation times than the fluctuation patterns HP12 and HP22.

[0167] The variation patterns HP61 and HP71 are variation patterns in which no reach is formed in the performance game (during execution of the special game) and a final performance is executed that can be identified as the last special game controlled to the first high base state.

[0168] In this embodiment, a plurality of types of fluctuation pattern determination tables for determining a fluctuation pattern are stored in the main control ROM 40b. That is, in this embodiment, there are a plurality of types of fluctuation pattern determination tables. In this embodiment, the condition for determining a fluctuation pattern by referring to the fluctuation pattern determination table corresponds to a predetermined determination condition. In this embodiment, this fluctuation pattern determination table is a table for determining a fluctuation pattern, but it is not a data structure as a table, and it is sufficient if it is a data group for determining a fluctuation pattern.

[0169] The plurality of types of fluctuation pattern determination tables include fluctuation pattern determination tables T01, T11 to T14. Any one of the plurality of types of fluctuation pattern determination tables is referred to, and a fluctuation pattern is determined based on the referred fluctuation pattern determination table. In this embodiment, the referenced fluctuation pattern determination table is determined based on the game state in which the jackpot lottery was won, the type of jackpot, the game state after the jackpot game ends, and the number of times the special game is executed. In this embodiment, the fluctuation pattern determination table T01 is a table referenced in the low base state, and the fluctuation pattern determination tables T11 to T14 are tables referenced in the high base state. In particular, the fluctuation pattern determination tables T11 to T13 are tables referenced in the first high base state, and the fluctuation pattern determination table T14 is a table referenced in the first high base state and the second high base state.

[0170] Specifically, the fluctuation pattern determination table T01 is a table capable of determining any one of the fluctuation patterns HP01 to HP03, HP11, HP12, HP21, and HP22 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T01 is a table capable of determining any one of the fluctuation patterns HP03 and HP21 as the fluctuation pattern of the second special game. As will be described in detail later, the fluctuation pattern determination table T01 is a table that is referred to when the current game state is a low base state. That is, the fluctuation pattern determination table T01 is a table in the low base state. In particular, the fluctuation pattern determination table T01 is a table from being controlled to the low base state to being controlled to the second high base state when a jackpot based on the symbol Za occurs in the low base state and the high base state, and after the jackpot game ends, the jackpot is controlled to the first high base state, then the low base state, and then the second high base state.

[0171] The fluctuation pattern determination table T11 is a table capable of determining one of the fluctuation patterns HP35 and HP52 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T11 is a table capable of determining one of the fluctuation patterns HP31, HP33, HP41, and HP51 as the fluctuation pattern of the second special game. Although described in detail later, the fluctuation pattern determination table T11 is a table that is referenced when a jackpot based on the symbol ZA is reached and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

[0172] The fluctuation pattern determination table T12 is a table that can determine any one of the fluctuation patterns HP32 and HP53 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T12 is a table that can determine any one of the fluctuation patterns HP31, HP34, HP41, HP51, and HP54 as the fluctuation pattern of the second special game. Although the details will be described later, the fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the symbols Zb and Zc is reached and the current game state is the first high base state after the jackpot game ends, except for the 100th special game. The fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the symbol Za is reached in the low base state and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

[0173] The fluctuation pattern determination table T13 is a table that can determine either the fluctuation pattern HP61 or HP71 as the fluctuation pattern of the special game. Although the details will be described later, the fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols Zb and Zc occurs, and the current game state is the first high base state in the 100th special game after the jackpot game ends. The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbol Za occurs in a low base state, and the current game state is the first high base state in the 100th special game after the jackpot game ends.

[0174] The fluctuation pattern determination table T14 is a table capable of determining either one of the fluctuation patterns HP35 and HP53 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T14 is a table capable of determining either one of the fluctuation patterns HP35 and HP54 as the fluctuation pattern of the second special game. Although details will be described later, the fluctuation pattern determination table T14 is a table that is referenced when a jackpot based on the symbol Za occurs in the high base state and the current gaming state is the first high base state after the jackpot game ends. The fluctuation pattern determination table T14 is a table that is referenced when the current gaming state is the second high base state. In this way, the fluctuation pattern determination table T14 is a table that may be referenced both when controlled to the first high base state and when controlled to the second high base state. In addition, in this embodiment, the fluctuation pattern determination table in the second high base state does not include the fluctuation pattern determination tables T01 and T11 to T13, but includes the fluctuation pattern determination table T14.

[0175] In this embodiment, the fluctuation pattern HP35 is a fluctuation pattern that can be determined by both the fluctuation pattern determination table T11 and the fluctuation pattern determination table T14. The fluctuation patterns HP53 and HP54 are fluctuation patterns that can be determined by both the fluctuation pattern determination table T12 and the fluctuation pattern determination table T14.

[0176] In addition, in this embodiment, the determination probability of the miss reach variation pattern is determined in the plurality of types of variation pattern determination tables. In detail, the variation pattern determination table T01 is a table in which 23 / 241 is determined as the determination probability of the miss reach variation pattern when the first special game is executed. The variation pattern determination table T11 is a table in which 9 / 241 is determined as the determination probability of the miss reach variation pattern when the second special game is executed. The variation pattern determination table T12 is a table in which 6 / 241 is determined as the determination probability of the miss reach variation pattern when the second special game is executed. In any other case, the miss reach variation pattern is not determined. In this way, the variation pattern determination tables T01, T11, and T12 are tables in which the miss reach variation pattern is determined (can be determined). On the other hand, the variation pattern determination tables T13 and T14 are tables in which the miss reach variation pattern is not determined (cannot be determined). The fluctuation pattern determination tables T01, T11, T12, and T14 are tables with different determination probabilities for determining a fluctuation pattern with reach performance when the jackpot lottery is not won. Also, the fluctuation pattern determination tables T11, T12, and T14 are tables with a lower determination probability for determining a fluctuation pattern with reach performance when the jackpot lottery is not won than the fluctuation pattern determination table T01. Also, the fluctuation pattern determination table T14 can be said to be a table in which a miss reach fluctuation pattern is more difficult to determine than the fluctuation pattern determination tables T01, T11, and T12.

[0177] Also, the fluctuation pattern determination table T11 is a table in which any one of the fluctuation patterns HP31, HP33, HP35, and HP41 is determined when the jackpot lottery is not won. The fluctuation pattern determination table T12 is a table in which any one of the fluctuation patterns HP31, HP34, and HP41 is determined when the jackpot lottery is not won. And the fluctuation pattern determination table T14 is a table in which the fluctuation pattern HP35 is determined when the jackpot lottery is not won. In other words, the fluctuation pattern determination table T14 is a table in which the fluctuation pattern HP35 is determined with a higher probability than the fluctuation pattern determination tables T11 and T12 when the jackpot lottery is not won.

[0178] Moreover, the fluctuation pattern determination table T11 is a table in which either the fluctuation pattern HP51 or HP52 is determined when the jackpot lottery is won. The fluctuation pattern determination table T12 is a table in which either the fluctuation pattern HP51, HP53, or HP54 is determined when the jackpot lottery is won. The fluctuation pattern determination table T14 is a table in which either the fluctuation pattern HP53 or HP54 is determined when the jackpot lottery is won. In other words, the fluctuation pattern determination table T14 is a table in which the fluctuation pattern HP53 or HP54 is determined with a higher probability than the fluctuation pattern determination tables T11 and T12 when the jackpot lottery is won.

[0179] In this embodiment, the fluctuation pattern HP31 corresponds to the first miss fluctuation pattern, and the fluctuation pattern HP35, which has a shorter fluctuation time than the fluctuation pattern HP31, corresponds to the second miss fluctuation pattern. In this embodiment, the fluctuation pattern HP51 corresponds to the first big win fluctuation pattern, and the fluctuation patterns HP53 and HP54, which have a shorter fluctuation time than the fluctuation pattern HP51, correspond to the second big win fluctuation pattern.

[0180] In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T01 corresponds to the normal determination condition. In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T11 corresponds to the first specific determination condition. In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T12 corresponds to the second special determination condition. In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T14 corresponds to the first special determination condition and the second specific determination condition.

[0181] In this embodiment, the main control CPU 40a, upon the start of the ending time, specifies the game state when the jackpot lottery is won, the type of jackpot, and whether or not the game ball passed through the special passing area 36 during the jackpot game, and stores the specified items in the main control RAM 40c. Then, the main control CPU 40a sets information capable of specifying the determined first upper limit number of times in the variation number counter. The variation number counter is assigned to the main control RAM 40c, and is a counter for counting the number of times the special game is executed after the base state changes. Specifically, when the main control CPU 40a specifies that the game state when the jackpot lottery is won is a high base state, the type of jackpot is a jackpot based on the pattern Za, and the game ball passed through the special passing area 36 during the jackpot game, it sets the variation number counter to "697" as the first upper limit number of times. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of jackpot is a jackpot based on the pattern Za, and the game ball has not passed through the special passing area 36 during the jackpot game, it sets the first upper limit number of times to "597" in the fluctuation counter. In other cases, the main control CPU 40a sets the first upper limit number of times to "100" in the fluctuation counter.

[0182] Then, each time the special game is executed, the main control CPU 40a subtracts "1" from the variation counter when the variation counter is not set to "0." In this embodiment, the main control CPU 40a subtracts "1" from each of the counters when the special game ends, but the present invention is not limited to this. For example, the main control CPU 40a may subtract "1" from each of the counters when the special game starts.

[0183] In addition, when the main control CPU 40a determines a variation pattern in the special pattern start processing, it refers to a variation pattern determination table based on the game state when the jackpot lottery was won, the type of jackpot, whether or not the game ball passed through the special passing area 36 during the jackpot game, the value set in the main base state flag, and the value set in the variation count counter.

[0184] In this embodiment, the presentation mode is controlled to be able to be changed on the condition that each winning game ends or a special game starts. The presentation mode corresponds to the type of background image and text image of the presentation display device 27, and can be specified by the player from at least one of the background image and text image, and is an image that is displayed regardless of the type of the variation pattern. The presentation mode can be executed over multiple consecutive special games.

[0185] As shown in Fig. 8, there are a plurality of types of rendering modes in this embodiment. The plurality of types of rendering modes are roughly divided into four types, namely, rendering modes MA to MD. Presentation mode MA is a presentation mode when in a low base state, and presentation modes MB to MD are presentation modes when in a high base state. In particular, in this embodiment, presentation modes MB and MC are presentation modes when in the first high base state, and presentation mode MD is a presentation mode when in the first high base state and the second high base state. Also, in this embodiment, presentation mode MA is a presentation mode that can be controlled only when in a low probability state, and is not controlled when in a high probability state. Presentation modes MB to MD are presentation modes that can be controlled in both a high probability state and a low probability state, and are presentation modes that may be controlled when in a high probability state.

[0186] As shown in Fig. 9, when it is controlled to the low base state, it is controlled to the presentation mode MA. On the other hand, when it is controlled to the high base state, it is controlled to one of the presentation modes MB to MD. In particular, in this embodiment, when it is controlled to the first high base state, it is controlled to one of the presentation modes MB to MD, and when it is controlled to the second high base state, it is controlled to the presentation mode MD.

[0187] Regardless of whether the machine is controlled to the low base state or the high base state, if a jackpot based on the symbol ZA is obtained, the machine transitions to the presentation mode MB after the jackpot game ends. Regardless of whether the machine is controlled to the low base state or the high base state, if a jackpot based on the symbol Zb, Zc is obtained, the machine transitions to the presentation mode MC after the jackpot game ends. If a jackpot based on the symbol Za is obtained when the machine is controlled to the low base state, the machine transitions to the presentation mode MC after the jackpot game ends. If a jackpot based on the symbol Za is obtained when the machine is controlled to the high base state, the machine transitions to the presentation mode MD after the jackpot game ends. When the machine is controlled to the low probability state and a special game is played a special number of times, the low base state ends, and the machine is controlled to the second high base state, the machine transitions to the presentation mode MD. In this way, the presentation mode MD can be said to be a presentation mode that is used both when a jackpot based on the symbol Za is obtained when the machine is controlled to the high base state and when a special game is played a special number of times when the machine is controlled to the low probability state.

[0188] When the high base state is controlled, the high base state end condition is satisfied, and when the low base state is controlled, the mode transitions to the presentation mode MA. In this embodiment, when the first high base state is controlled after the end of the big win game, the mode transitions to one of the presentation modes MB to MD. When the first high base state is ended and the low base state is controlled after the end of the big win game, in the special game with the first upper limit number of times, the mode transitions to the presentation mode MA. When the second high base state is controlled, the second high base state is ended after the special game with the second upper limit number of times is played, and when the low base state is controlled, the mode transitions to the presentation mode MA.

[0189] Next, the control relating to the presentation mode executed by the sub-control CPU 41a will be described. When the sub-control CPU 41a determines that the power supply is turned on and that the device is in a low base state based on control information from the main control CPU 40a, the sub-control CPU 41a sets the presentation mode flag to information indicating the presentation mode MA. The presentation mode flag is assigned to the sub-control RAM 41c and is a flag indicating the presentation mode to be held.

[0190] When the sub-control CPU41a is powered on and determines that the state is the first high base state based on the control information from the main control CPU40a, the sub-control CPU41a sets the presentation mode flag to information indicating the presentation mode MB. The sub-control CPU41a determines the game state when the jackpot lottery is won, the type of the jackpot, and whether or not the game ball passed through the special passing area 36 during the jackpot game, triggered by the input of an ending command, and sets the presentation mode flag to information indicating the presentation mode. In this embodiment, when the sub-control CPU41a determines that the jackpot is based on the symbol ZA, the sub-control CPU41a sets the presentation mode flag to information indicating the presentation mode MB. When the sub-control CPU41a determines that the jackpot is based on the symbol Za in the high base state, the sub-control CPU41a sets the presentation mode flag to information indicating the presentation mode MD. When the sub-control CPU41a determines that the jackpot is otherwise, the sub-control CPU41a sets the presentation mode flag to information indicating the presentation mode MC. When the sub-control CPU 41a is powered on and determines that the second high base state is present based on control information from the main control CPU 40a, it sets the presentation mode flag to information indicating the presentation mode MD. In addition, the sub-control CPU 41a sets the presentation mode flag to information indicating the presentation mode MA in response to input of a low base state command in the high base state.

[0191] Then, the sub-control CPU 41a causes the performance display device 27 to display a background image of a type corresponding to the value set in the performance mode flag. In this way, the presentation mode MA is a presentation mode that can be continuously controlled in at least a plurality of consecutive special games among the special games from the start to the end of the control to the low base state. When a jackpot based on the symbol Za occurs and the jackpot game is controlled to the first high base state after the end of the jackpot game, then the low base state, and then the second high base state, the presentation mode MA is a presentation mode that is controlled at least in any of the periods from the control to the low base state to the control to the second high base state.

[0192] Moreover, the presentation mode MB is a presentation mode to which the player is shifted (controlled) when a jackpot based on the symbol ZA occurs and the game is controlled to the first high base state after the jackpot game ends. The presentation mode MC is a presentation mode to which the player is shifted (controlled) when a jackpot based on the symbol Za occurs in the low base state and the game is controlled to the first high base state after the jackpot game ends, and is a presentation mode that can be continuously controlled in at least a plurality of consecutive special games among the special games from the start to the end of the control to the first high base state.

[0193] The presentation mode MD is a presentation mode which is transitioned to (controlled) when a jackpot based on the pattern Za occurs in the high base state and control is exercised to the first high base state after the jackpot game ends, and which can then be continuously controlled in at least a number of consecutive special games among the special games from the start to the end of control to the first high base state.

[0194] The presentation mode MD is a presentation mode which is transitioned to (controlled) when control is exercised from the low base state to the second high base state, and can be continuously controlled thereafter in at least a number of consecutive special games among the special games from the start to the end of control to the second high base state.

[0195] In this embodiment, the sub-control CPU 41a that controls the presentation mode corresponds to the presentation mode control means. In this embodiment, the presentation mode MA corresponds to the normal presentation mode, the presentation mode MB corresponds to the first specific presentation mode, the presentation mode MC corresponds to the second special presentation mode, and the presentation mode MD corresponds to the first special presentation mode and the second specific presentation mode, respectively.

[0196] Here, the game state, the conditions for determining the variation pattern, and the presentation mode will be described in detail with reference to FIG. As shown in FIG. 10(a), when the high probability state and the first high base state are controlled after the end of a jackpot game, the type of variation pattern determination table referenced in accordance with the number of times the special game is executed and the presentation mode controlled differ depending on the base state when the jackpot lottery is won and the type of jackpot.

[0197] Specifically, if a jackpot is hit based on the symbol ZA and the state is controlled to the high probability state and the first high base state after the jackpot game ends, the 1st to 100th special games are controlled to the high probability state and the first high base state after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T11 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game ends, the 1st to 100th special games are controlled to the presentation mode MB. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the low base state.

[0198] After the big win game ends, the 101st to 698th special games are controlled to a low probability state and a low base state. After the big win game ends, the 101st to 698th special games are controlled to a low probability state and a low base state by referring to the variation pattern determination table T01 and controlling to the presentation mode MA. Then, when the 698th special game ends after the big win game ends, the low probability state and the second high base state are controlled.

[0199] After the jackpot game ends, in the 699th to 1458th special games, the game is controlled to the low probability state and the second high base state. After the jackpot game ends, in the 699th to 1458th special games, the variation pattern determination table T14 is referenced and the game is controlled to the presentation mode MD. Then, when the 1458th special game ends after the jackpot game ends, the game is controlled to the low probability state and the low base state.

[0200] After the big win game ends, the special game from the 1459th time onwards is controlled to the low probability state and low base state. After the big win game ends, the special game from the 1459th time onwards is controlled to the low probability state and low base state. After the big win game ends, the special game from the 1459th time onwards is controlled to the presentation mode MA by referring to the variation pattern determination table T01.

[0201] Next, when a jackpot based on the symbols Zb and Zc is obtained and the state is controlled to the high probability state and the first high base state after the jackpot game ends, the 1st to 100th special games are controlled to the high probability state and the first high base state after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T12 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game ends, the 1st to 100th special games are controlled to the presentation mode MC. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the low base state. In this case, the 101st and subsequent special games after the jackpot game ends are controlled to the high probability state and the first high base state, so the explanation will be omitted.

[0202] In addition, in the case where a jackpot based on the pattern Za occurs in the low base state and control is exercised to the high probability state and the first high base state after the jackpot game ends, this is the same as the case where a jackpot based on the patterns Zb, Zc occurs in all special games after the jackpot game ends and control is exercised to the high probability state and the first high base state after the jackpot game ends, so an explanation will be omitted.

[0203] Next, in the case where a jackpot based on the symbol Za occurs in the high base state, and control is made to the high probability state and the first high base state after the jackpot game ends, control is made to the high probability state and the first high base state in the 1st to 100th special games after the jackpot game ends. After the jackpot game ends, control is made to the presentation mode MD by referring to the variation pattern determination table T14 in the 1st to 100th special games. Then, when the 100th special game ends after the jackpot game ends, control is made to the low probability state and the first high base state.

[0204] After the big win game ends, the 101st to 697th special games are controlled to the low probability state and the first high base state. After the big win game ends, the 101st to 697th special games are controlled to the low probability state and the first high base state by referring to the variation pattern determination table T14 and controlling to the presentation mode MD. Then, when the 697th special game ends after the big win game ends, the low probability state and the low base state are controlled.

[0205] After the jackpot game ends, in the 698th special game, the state is controlled to a low probability state and a low base state. After the jackpot game ends, in the 698th special game, the variation pattern determination table T01 is referenced and the mode is controlled to the presentation mode MA. Then, when the 698th special game ends after the jackpot game ends, the state is controlled to a low probability state and a second high base state. In this case, in the 699th and subsequent special games after the jackpot game ends, the same as in the other cases, so a description is omitted.

[0206] In particular, in this embodiment, after the end of the jackpot game, in the special games up to the 697th time, the game is controlled to the first high base state, so that the execution of the second special game is highly likely to be suspended. Also, the fluctuation pattern determination table T01 is a table in which a fluctuation pattern having a shorter fluctuation time than the fluctuation pattern of the first special game is determined as the fluctuation pattern of the second special game. Therefore, after the end of the jackpot game, in the 698th special game, although the game is controlled to the low base state, the second special game having a short fluctuation time is highly likely to be executed, so that the game can be smoothly progressed and interest in the game can be increased.

[0207] As shown in FIG. 10(b), when the game is controlled to a low probability state and a first high base state after the end of a jackpot game, the type of variation pattern determination table referenced in accordance with the number of times the special game is played and the presentation mode controlled differ depending on the base state when the jackpot lottery is won and the type of jackpot.

[0208] Specifically, if a jackpot is hit based on the symbol ZA and the state is controlled to the low probability state and the first high base state after the jackpot game ends, the 1st to 100th special games are controlled to the low probability state and the first high base state after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T11 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game ends, the 1st to 100th special games are controlled to the presentation mode MB. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the low base state.

[0209] After the big win game ends, the 101st to 598th special games are controlled to a low probability state and a low base state. After the big win game ends, the 101st to 598th special games are controlled to a low probability state and a low base state by referring to the variation pattern determination table T01 and controlling to the presentation mode MA. Then, when the 598th special game ends after the big win game ends, the low probability state and the second high base state are controlled.

[0210] After the big win game is over, in the 599th to 1358th special games, the game is controlled to the low probability state and the second high base state. After the big win game is over, in the 599th to 1358th special games, the variation pattern determination table T14 is referenced and the game is controlled to the presentation mode MD. Then, when the 1358th special game is over after the big win game is over, the game is controlled to the low probability state and the low base state.

[0211] After the big win game ends, the special game from the 1359th time onwards is controlled to the low probability state and low base state. After the big win game ends, the special game from the 1359th time onwards is controlled to the low probability state and low base state. After the big win game ends, the special game from the 1359th time onwards is controlled to the presentation mode MA by referring to the variation pattern determination table T01.

[0212] Next, when a jackpot based on the symbols Zb and Zc is obtained and the state is controlled to the low probability state and the first high base state after the jackpot game is completed, the 1st to 100th special games are controlled to the low probability state and the first high base state after the jackpot game is completed. After the jackpot game is completed, the variation pattern determination table T12 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game is completed, the 1st to 100th special games are controlled to the presentation mode MC. Then, when the 100th special game is completed after the jackpot game is completed, the state is controlled to the low probability state and the low base state. In this case, the 101st and subsequent special games after the jackpot game are controlled to the low probability state and the first high base state after the jackpot game is completed, and therefore the explanation is omitted.

[0213] In addition, in the case where a jackpot based on the pattern Za occurs in the low base state and control is exercised to the low probability state and the first high base state after the jackpot game ends, this is the same as the case where a jackpot based on the patterns Zb and Zc occurs in all special games after the jackpot game ends and control is exercised to the low probability state and the first high base state after the jackpot game ends, so an explanation will be omitted.

[0214] Next, in the case where a jackpot based on the symbol Za occurs in the high base state, and the state is controlled to the low probability state and the first high base state after the jackpot game ends, the state is controlled to the low probability state and the first high base state in the 1st to 100th special games after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T14 is referenced in the 1st to 100th special games, and the state is controlled to the presentation mode MD. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the first high base state.

[0215] After the big win game ends, the 101st to 597th special games are controlled to the low probability state and the first high base state. After the big win game ends, the 101st to 597th special games are controlled to the low probability state and the first high base state by referring to the variation pattern determination table T14 and controlling to the presentation mode MD. Then, when the 597th special game ends after the big win game ends, the low probability state and the low base state are controlled.

[0216] After the jackpot game ends, in the 598th special game, the game is controlled to a low probability state and a low base state. After the jackpot game ends, in the 598th special game, the variation pattern determination table T01 is referenced and the game is controlled to the presentation mode MA. Then, when the 598th special game ends after the jackpot game ends, the game is controlled to a low probability state and a second high base state. In this case, in the 599th and subsequent special games after the jackpot game ends, the game is the same as in the other cases, so a description is omitted.

[0217] In this embodiment, various effects can be executed by the effect display device 27. The various effects include an entry effect and a final effect. In this embodiment, the entry performance is an effect that is executed when the game is controlled to a high base state. The entry performance is an effect in which an introduction performance, a mode notification performance, and a first right hit notification performance are executed in sequence. The introduction performance is, for example, a performance in which a castle gate closes, and it is possible to identify that the execution of the entry performance has begun. The mode notification performance is an effect in which the controlled performance mode is identified, and a character image and a background image corresponding to the controlled performance mode are displayed. The first right hit notification performance is an notification performance in which it is possible to identify that the game ball will flow down to the right side of the game area 21 during the execution of the entry performance.

[0218] In addition, in this embodiment, the entry performance includes a first entry performance and a second entry performance. The first entry performance is a performance executed when controlled to the first high base state, and is a performance that can be specified as being controlled to the high base state. On the other hand, the second entry performance is a performance executed when controlled to the second high base state, and is a performance that can be specified as being controlled to the high base state.

[0219] In this embodiment, the final effect is an effect executed during the execution of the last special game controlled in the first high base state, and is an effect executed when the variation patterns HP61, HP71 are determined.

[0220] The final performance control process executed by the sub-control CPU 41a will be described below. The final performance control process is called at predetermined intervals. The sub-control CPU 41a, triggered by the input of a game start command, controls the effect display device 27 to execute the final effect when the variation pattern designated by the game start command is the variation pattern HP61, HP71, and ends the final effect control process. In this way, the effect display device 27 executes the final effect when the variation pattern HP61, HP71 is determined. In other words, the final effect is an effect executed during the 100th special game after the end of the jackpot game when a jackpot based on the symbols ZA, Zb, Zc is obtained, or when a jackpot based on the symbol Za is obtained in a low base state, and is an effect that is not executed after the end of the jackpot game when a jackpot based on the symbol Za is obtained in a high base state.

[0221] Next, the first entry performance control process executed by the sub-control CPU 41a will be described. The first entry performance control process is a process that is called at every predetermined cycle. The sub-control CPU 41a executes control to execute the first entry performance in response to the input of the ending command, and ends the first entry performance control process. As a result, when the performance display device 27 is controlled to the first high base state after the end of the big win game, it executes the first entry performance that can specify that it is controlled to the high base state from the timing during the big win game.

[0222] Next, the second entry performance control process executed by the sub-control CPU 41a will be described. The second entry performance control process is a process that is called at every predetermined cycle. The sub-control CPU41a judges whether the second high base state command has been input. If it is judged that the second high base state command has been input, the sub-control CPU41a executes a second entry performance start process to start the execution of the second entry performance, and ends the second entry performance control process. Thus, in this embodiment, the second entry performance is executed when the game is controlled to the second high base state after the end of the jackpot game, both when a jackpot based on the symbol Za occurs in the high base state and when it does not occur.

[0223] As described above in detail, this embodiment has the following advantages. (1) When a jackpot based on the Za symbol occurs in the low base state and control is made to the first high base state after the jackpot game ends, the number of times the special game is executed from when the player is controlled to the low base state to when the player is controlled to the second high base state is smaller than when a jackpot based on the Za symbol occurs in the high base state and control is made to the first high base state after the jackpot game ends in the low base state. Therefore, it is possible to heighten the expectation of being controlled to the second high base state, and to make the player pay attention to whether the player is controlled to the high base state or the low base state when the jackpot occurs, thereby improving the interest in the game.

[0224] (2) When a jackpot based on the Za symbol occurs in the high base state, and after the jackpot game ends, the system is controlled to the first high base state, and 597 or 697 special games are executed without winning the jackpot lottery. When a jackpot based on the Za symbol occurs in the low base state, and after the jackpot game ends, the system is controlled to the first high base state, and 100 special games are executed without winning the jackpot lottery, the system is controlled to the low base state. 597 or 697 times is more than 100 times, and the number of special games, which is the number of times the special game is executed from the time the system is controlled to the low probability state until the system is controlled to the second high base state, is greater than 597 times. Therefore, when a jackpot based on the Za symbol occurs in the high base state, and after the jackpot game ends, the system is controlled to the first high base state, and after the jackpot game ends, the system is controlled to the first high base state with a greater number of special games than when the system is controlled to the first high base state. Therefore, in order to specify the number of special games controlled to the first high base state, it is possible to draw attention to whether the state is controlled to the high base state or the low base state when a jackpot lottery is won, thereby increasing interest in the game.

[0225] (3) In addition, the number of times the special game is executed from when the low base state is controlled to when the second high base state is controlled differs between when a jackpot based on the symbol ZA is won and the first high base state is controlled after the jackpot game ends, and when a jackpot based on the symbol Za is won in the high base state and the first high base state is controlled after the jackpot game ends. This can heighten the expectation of being controlled to the second high base state, and can draw attention to whether the type of jackpot is a jackpot based on the symbol ZA or a jackpot based on the symbol Za, thereby improving interest in the game.

[0226] (4) In particular, the second special game is a special game that is more advantageous to the player than the first special game. The number of times the special game is executed between being controlled to the low base state and being controlled to the second high base state is smaller when the pattern Za is obtained in the high base state and the system is controlled to the first high base state after the end of the jackpot game than when the jackpot is obtained based on the pattern ZA and the system is controlled to the first high base state after the end of the jackpot game. Therefore, a special benefit can be given to the player for winning the jackpot lottery in the second special game, which is more advantageous to the player than the first special game, and the player's interest in the game can be increased.

[0227] (5) When a jackpot based on the symbol ZA is obtained, the system is controlled to the first high base state after the jackpot game ends, and then 100 special games are played without winning the jackpot lottery, the system is controlled to the low base state. On the other hand, when a jackpot based on the symbol Za is obtained in the high base state, the system is controlled to the first high base state after the jackpot game ends, and then 597 or 697 special games are played without winning the jackpot lottery, the system is controlled to the low base state. 597 times is greater than 100 times, and 599 times from being controlled to the low probability state to being controlled to the second high base state is greater than 597 times. Therefore, when a jackpot based on the symbol Za is obtained in the high base state, and the system is controlled to the first high base state after the jackpot game ends, the system is controlled to the first high base state with a greater number of special games than when the system is controlled to the first high base state after the jackpot game ends. Therefore, in order to determine the number of special games controlled to the first high base state, it is possible to draw attention to whether the type of jackpot is a jackpot based on the pattern ZA or a jackpot based on the pattern Za, thereby increasing interest in the game.

[0228] (6) In addition, when a jackpot based on the Za pattern is hit and the jackpot game is ended and the jackpot game is controlled to the first high base state, even if the jackpot game is ended and ...

[0229] (7) After the end of the jackpot game, the high probability state can be controlled until 100 special games are executed, and the 100 times that can be controlled to the high probability state are smaller than the 597 and 697 times that can be controlled to the first high base state. Therefore, when a jackpot based on the symbol Za occurs in the high base state and the high probability state and the first high base state are controlled after the end of the jackpot game, the expectation of being continuously controlled to the first high base state can be heightened, even after being controlled from the high probability state to the low probability state, and interest in the game can be improved.

[0230] (8) When controlled to the second high base state, the game is controlled to the second high base state until 759 special games are executed without winning the jackpot lottery. The number of times that the game is controlled to the second high base state is greater than the number of special games, 579 and 679, that are executed from the time that the game is controlled to the low probability state until the game is controlled to the second high base state. Therefore, the number of times that the special game is executed when the game is controlled to the second high base state is greater than the number of times that the special game is executed from the time that the game is controlled to the low probability state until the game is controlled to the second high base state, which can heighten expectations for being controlled to the second high base state and can increase interest in the game.

[0231] (9) When a jackpot based on the symbol Za occurs in the high base state, and after the jackpot game ends, the machine is controlled to the first high base state and then to the low base state, the number of times the special game is executed from the control to the low base state to the control to the second high base state is less than 597. This can heighten the expectation of being controlled from the low base state to the second high base state, and can enhance interest in the game.

[0232] (10) When a jackpot based on the symbol Za occurs in the high base state, and after the jackpot game ends, the machine is controlled to the first high base state, and then controlled to the low base state, the number of times the special game is executed from the control to the low base state to the control to the second high base state is smaller than the reserved upper limit number. Therefore, if the reserved number of special games reaches the reserved upper limit number before the control from the first high base state to the low base state, the machine will be controlled to the second high base state at least after the reserved upper limit number of special games are executed. Therefore, it is possible to heighten the expectation of being controlled from the low base state to the second high base state, and to increase interest in the game.

[0233] (11) The number of times (597 times) that the special game can be executed continuously in the low probability state and the first high base state is greater than the reciprocal of the probability of winning the jackpot lottery in the low probability state. Therefore, even if the low probability state and the high base state are continuously controlled until 597 special games are executed without a jackpot after the end of the jackpot game, the possibility of winning the jackpot lottery can be increased, and the expectation for winning the jackpot lottery can be heightened, thereby improving the interest in the game.

[0234] (12) The second upper limit number of times is a number greater than the reciprocal of the winning probability of the jackpot lottery in the low probability state. Therefore, even if the second high base state and the low probability state are controlled until the second upper limit number of special games are played, the possibility of winning the jackpot lottery can be increased before the second upper limit number of special games are played, and the expectation for winning the jackpot lottery can be heightened, thereby improving the interest in the game.

[0235] (13) The fluctuation pattern determination table T14 is a table in the first high base state in which a jackpot based on the symbol Za occurs in the high base state and is controlled after the jackpot game ends. The fluctuation pattern determination table T12 is a table in the first high base state in which a jackpot based on the symbol Za occurs in the low base state and is controlled after the jackpot game ends. The fluctuation pattern determination table in the second high base state does not have the fluctuation pattern determination table T12, but has the fluctuation pattern determination table T14. Therefore, the fluctuation pattern can be determined based on the fluctuation pattern determination table T14 in the same way when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends and when the game is controlled to the second high base state. Therefore, the fluctuation pattern determination table can be made common, the presentation effect can be enhanced, and the interest in the game can be improved.

[0236] (14) The variation pattern can be determined so that it is different between when a jackpot based on the symbol Za occurs in the high base state and when the jackpot game is controlled to the first high base state and the second high base state after the jackpot game is completed, and when a jackpot based on the symbol Za occurs in the low base state and when the jackpot game is controlled to the first high base state after the jackpot game is completed. Therefore, the presentation effect can be improved, and the interest in the game can be increased.

[0237] (15) When the jackpot lottery is not won, the fluctuation pattern determination table T14 is a table that determines the fluctuation pattern HP35, which has a shorter fluctuation time than the fluctuation pattern HP31, with a higher probability than the fluctuation pattern determination table T12. Therefore, when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends, and when the game is controlled to the second high base state, the fluctuation time of the special game is more likely to be shorter than when a jackpot based on the symbol Za occurs in the low base state and the game is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be improved.

[0238] (16) When the jackpot lottery is won, the fluctuation pattern determination table T14 is a table that determines the fluctuation patterns HP53 and HP54, which have a shorter fluctuation time than the fluctuation pattern HP51, with a higher probability than the fluctuation pattern determination table T12. Therefore, when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends, and when the game is controlled to the second high base state, the fluctuation time of the special game is more likely to be shorter than when a jackpot based on the symbol Za occurs in the low base state and the game is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be improved.

[0239] (17) The fluctuation pattern determination table T14 is a table in the first high base state in which a jackpot based on the symbol Za occurs in the high base state and is controlled after the jackpot game ends. The fluctuation pattern determination table T11 is a table in the first high base state in which a jackpot based on the symbol ZA occurs and is controlled after the jackpot game ends. The fluctuation pattern determination table in the second high base state does not have the fluctuation pattern determination table T11, but has the fluctuation pattern determination table T14. Therefore, it is possible to determine a fluctuation pattern differently between when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends and when the game is controlled to the second high base state, and when a jackpot based on the symbol ZA occurs and the game is controlled to the first high base state after the jackpot game ends. Therefore, it is possible to enhance the presentation effect and improve the interest in the game.

[0240] (18) When the jackpot lottery is not won, the fluctuation pattern determination table T14 is a table that determines the fluctuation pattern HP35, which has a shorter fluctuation time than the fluctuation pattern HP31, with a higher probability than the fluctuation pattern determination table T11. Therefore, when a jackpot based on the symbol Za occurs in the high base state, and when the jackpot game is controlled to the first high base state or the second high base state after the jackpot game ends, the fluctuation time of the special game is more likely to be shorter than when a jackpot based on the symbol ZA occurs and the jackpot game is controlled to the first high base state after the jackpot game ends. Therefore, the execution of the special game can be smoothly carried out, and interest in the game can be improved.

[0241] (19) When the jackpot lottery is won, the fluctuation pattern determination table T14 is a table that determines the fluctuation patterns HP53 and HP54, which have a shorter fluctuation time than the fluctuation pattern HP51, with a higher probability than the fluctuation pattern determination table T11. Therefore, when a jackpot based on the symbol Za occurs in the high base state, and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state, the fluctuation time of the special game is more likely to be shorter than when a jackpot based on the symbol ZA occurs and the jackpot game is controlled to the first high base state. Therefore, the execution of the special game can be smoothly carried out, and interest in the game can be improved.

[0242] (20) The fluctuation pattern determination table T01 is a table from being controlled to the low base state until being controlled to the second high base state when a jackpot based on the symbol Za occurs in the high base state, and when the jackpot game is ended and then controlled to the first high base state and then controlled to the low base state. Therefore, the fluctuation pattern determination table T01 is a table when a jackpot based on the symbol Za occurs, and when the jackpot game is ended and then controlled to the first high base state and then controlled to the low base state, regardless of the base state when the jackpot lottery is won. And, when a jackpot based on the symbol Za occurs in the high base state and when a jackpot based on the symbol Za occurs in the low base state, the fluctuation pattern can be determined based on the fluctuation pattern determination table T01 in the low base state. Therefore, the fluctuation pattern determination table can be made common, the presentation effect can be enhanced, and the interest in the game can be improved.

[0243] (21) In addition, the probability of determining the miss reach variation pattern is different between the variation pattern determination table T12 and the variation pattern determination table T14. Therefore, when a jackpot is generated based on the symbol Za in the high base state, and the jackpot lottery is not won, the miss reach variation pattern can be determined with the same determination probability when the jackpot is controlled to the first high base state after the jackpot game ends and when the jackpot is controlled to the second high base state. Therefore, the determination conditions can be made common, the presentation effect can be enhanced, and the interest in the game can be improved.

[0244] (22) In addition, when a jackpot based on the symbol Za occurs in the high base state and the system is controlled to the first high base state after the jackpot game ends, a miss reach fluctuation pattern can be determined with a different determination probability from when a jackpot based on the symbol Za occurs in the low base state and the system is controlled to the first high base state after the jackpot game ends. Therefore, the presentation effect can be enhanced, and interest in the game can be increased.

[0245] (23) The fluctuation pattern determination table T12 is a table that can determine a miss-reach fluctuation pattern, and the fluctuation pattern determination table T14 is a determination condition in which the probability of determining a miss-reach fluctuation pattern is lower than that of the fluctuation pattern determination table T12, and the miss-reach fluctuation pattern is not determined. Therefore, when a jackpot based on the symbol Za occurs in the high base state, and when the game is controlled to the first high base state and the second high base state after the jackpot game ends, a jackpot based on the symbol Za occurs in the low base state, and it is more difficult to determine a miss-reach fluctuation pattern than when the game is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be smoothly executed, and interest in the game can be improved.

[0246] (24) The fluctuation pattern determination tables T12 and T14 are determination conditions with a lower probability of determining a miss reach effect fluctuation pattern than the fluctuation pattern determination table T01. Therefore, when controlled to a high base state, a miss reach effect fluctuation pattern is more difficult to determine than when controlled to a low base state, so that the execution of the special game can be smoothly carried out and interest in the game can be improved.

[0247] (25) The fluctuation pattern determination table T11 and the fluctuation pattern determination table T14 have different determination probabilities for determining the miss reach fluctuation pattern. Therefore, when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends, and when a jackpot based on the symbol ZA occurs and the game is controlled to the first high base state after the jackpot game ends, the miss reach fluctuation pattern can be determined with different determination probabilities. Therefore, the presentation effect can be improved, and the interest in the game can be improved.

[0248] (26) The variation pattern determination table T11 is a table that can determine a miss-reach variation pattern, and the variation pattern determination table T14 is a determination condition in which the probability of determining a miss-reach variation pattern is lower than that of the variation pattern determination table T11, and the miss-reach variation pattern is not determined. Therefore, in the high base state, a jackpot is generated based on the symbol Za, and when the game is controlled to the first high base state and the second high base state after the jackpot game ends, a jackpot is generated based on the symbol ZA, and a miss-reach variation pattern is more difficult to determine than when the game is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be smoothly executed, and interest in the game can be improved.

[0249] (27) The fluctuation pattern determination tables T11 and T14 are determination conditions with a lower probability of determining a miss reach effect fluctuation pattern than the fluctuation pattern determination table T01. Therefore, when controlled to a high base state, a miss reach effect fluctuation pattern is more difficult to determine than when controlled to a low base state, so that the execution of the special game can be smoothly carried out, and interest in the game can be improved.

[0250] (28) The presentation mode MD is a presentation mode that is controlled when a jackpot based on the Za symbol occurs in the high base state and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state. The presentation mode MC is a presentation mode that is controlled when a jackpot based on the Za symbol occurs in the low base state and when the jackpot game is controlled to the first high base state after the jackpot game is completed. Therefore, the presentation mode MD can be controlled in the same way when a jackpot based on the Za symbol occurs in the high base state and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state after the jackpot game is completed. Therefore, the presentation mode can be made common, the presentation effect can be enhanced, and the interest in the game can be improved.

[0251] (29) In addition, when a jackpot based on the Za symbol occurs in the high base state and the system is controlled to the first high base state after the jackpot game ends, it is possible to control the system to different presentation modes, and when a jackpot based on the Za symbol occurs in the low base state and the system is controlled to the first high base state after the jackpot game ends. This can enhance the presentation effect and increase interest in the game.

[0252] (30) Presentation mode MB is a presentation mode that is controlled when a jackpot based on the symbol ZA occurs and the state is controlled to the first high base state after the jackpot game ends. Presentation mode MD is a presentation mode that is controlled both when a jackpot based on the symbol Za occurs in the high base state and when the state is controlled to the first high base state after the jackpot game ends and when the state is controlled to the second high base state. It is possible to control to different presentation modes when a jackpot based on the symbol Za occurs in the high base state and the state is controlled to the first high base state after the jackpot game ends, and when a jackpot based on the symbol Za occurs and the state is controlled to the first high base state after the jackpot game ends. Therefore, the presentation effect can be enhanced, and interest in the game can be improved.

[0253] (31) The presentation mode MD is a presentation mode that can be controlled continuously for at least a plurality of consecutive special games among the special games from the start to the end of the control to the high base state when a jackpot based on the Za symbol occurs in the high base state, and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state. Therefore, when a jackpot based on the Za symbol occurs in the high base state, and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state, it is possible to control to the presentation mode MD in a plurality of consecutive special games. Therefore, it is possible to standardize the presentation mode, improve the presentation effect, and increase the interest in the game.

[0254] (32) The presentation mode MA is a presentation mode that is controlled from the low base state to the second high base state when a jackpot based on the Za symbol is hit, and the jackpot game is controlled to the first high base state after the jackpot game is completed, and then the low base state is controlled, and then the second high base state is controlled. Therefore, it is possible to control to the presentation mode MA in the low base state in the same way when a jackpot based on the Za symbol is hit in the high base state and the jackpot game is controlled to the first high base state after the jackpot game is completed, and when a jackpot based on the Za symbol is hit in the low base state and the jackpot game is controlled to the first high base state after the jackpot game is completed. Therefore, it is possible to standardize the presentation mode, improve the presentation effect, and increase the interest in the game.

[0255] (33) The normal variable member 30 has different opening modes in normal winning games between the first high base state and the second high base state. This allows for diversity in the conditions for control to the high base state and the types of high base states, and also draws attention to the conditions for control to the high base state and the types of high base states. Furthermore, it allows attention to the opening modes in normal winning games, thereby improving interest in the game.

[0256] (34) The multiple types of opening modes as the opening mode of the normal variable member 30 in the first high base state are different from the single type of opening mode as the opening mode of the normal variable member 30 in the second high base state. Therefore, it is possible to provide diversity to the opening mode of the normal variable member 30 in the first high base state, and by making the opening mode different from that in the second high base state, it is possible to draw attention to whether the state is controlled in the first high base state or the second high base state, thereby increasing interest in the game.

[0257] (35) The multiple types of opening modes as the opening modes of the normal variable member 30 in the first high base state have the same total upper limit opening time during which the second starting hole 29 can be in the open state in one normal winning game. Therefore, it is possible to provide diversity to the opening modes of the normal variable member 30 in the first high base state, and by setting the same total upper limit opening time for the multiple types of opening modes, it is possible to maintain fairness in the entry of game balls into the second starting hole 29, thereby improving the interest in the game.

[0258] (36) The normal winning lottery is a lottery that is won with the same probability in the first high base state and the second high base state, and the fluctuation time of the normal game is the same in the first high base state and the second high base state. Therefore, the probability of winning the normal winning lottery can be made the same in the first high base state and the second high base state, and the fluctuation time of the normal game can be made the same, so that fairness can be maintained in the frequency of execution of the normal winning lottery and the normal game, and interest in the game can be improved.

[0259] (37) The opening state of the normal variable member 30 in the first high base state and the opening state of the normal variable member 30 in the second high base state have different total upper limit opening times during which the second starting hole 29 can be in an open state in one normal winning game. This makes it possible to vary the degree of advantage of the opening state of the normal variable member 30, thereby improving the interest in the game.

[0260] (38) The normal win game granted in the second high base state has a shorter upper limit control time for the normal win game than the normal win game granted in the first high base state. Therefore, the second high base state can increase the possibility of consuming the normal win game faster than the first high base state, and can draw attention to the type of high base state and the upper limit control time for the normal win game, thereby improving interest in the game.

[0261] (39) The opening state of the normal variable member 30 in the second high base state is longer than the opening state of the normal variable member 30 in the first high base state in the total upper limit opening time during which the second starting hole 29 can be in the open state in one normal winning game. Therefore, the degree of advantage regarding the total upper limit opening time can be made different between the first high base state and the second high base state, and attention can be drawn to the type of high base state and the total upper limit opening time, thereby improving interest in the game.

[0262] (40) The normal win game granted in the first high base state and the normal win game granted in the second high base state have different upper limit numbers of times that the normal variable member 30 can be in the open state in one normal win game, which draws attention to the type of high base state and the upper limit number of times that it can be opened, thereby increasing interest in the game.

[0263] (41) The multiple types of opening modes as the opening mode of the normal variable member 30 in the first high base state are opening modes in which the upper limit number of times that the normal variable member 30 can be in the open state in one normal winning game is multiple. The multiple types of opening modes have the same upper limit number of times that the normal variable member 30 can be in the open state in one normal winning game and the same closing time that the normal variable member 30 can be in the closed state in one normal winning game, and the upper limit opening time that the second starting port 29 can be in the open state once is different. For this reason, in the multiple types of opening modes for the opening mode of the normal variable member 30 in the first high base state, the upper limit number of times that the normal variable member 30 can be opened and the closing time are the same, while the upper limit opening time is different, so that the opening mode of the normal variable member 30 can be made diverse and attention can be drawn to the upper limit opening time, thereby improving the interest in the game.

[0264] (42) When the game is controlled to the second high base state, after the special game is played a special number of times, a second entry performance is executed, which can specify that the game will be controlled to the high base state (second high base state). Therefore, by executing the second entry performance when the game is controlled to the second high base state, it becomes possible to specify that the game will be controlled to the high base state, and the expectation for being controlled to the high base state can be heightened, and interest in the game can be increased.

[0265] (43) When the machine is controlled to the first high base state after the end of a jackpot game, a first entry performance is executed that can specify that the machine will be controlled to the high base state (first high base state) from the timing during the jackpot game. Therefore, even when the machine is controlled to the first high base state after the end of a jackpot game, the first entry performance is executed, so that the machine can specify that the machine will be controlled to the high base state (first high base state), which can heighten expectations for the machine being controlled to the high base state (first high base state), thereby improving interest in the game.

[0266] [Second embodiment] Next, a second embodiment of the present invention will be described. In the first embodiment, the jackpot based on the symbol Za is a jackpot of a special game in which the game ball is easy to pass through the special passing area 36, ​​and the first upper limit number of times is different depending on whether the jackpot based on the symbol Za is in a high base state or in a low base state, but this is not limited to this. In the second embodiment, there is a jackpot of a special game in which the game ball is hard to pass through the special passing area 36, ​​and the first upper limit number of times may be different depending on whether the jackpot is in a high base state or in a low base state. In the following description, the same reference numerals are used for configurations and control contents similar to those of the first embodiment already described, and duplicate descriptions are omitted or simplified.

[0267] As shown in FIG. 11, in the second embodiment, of the 100 types of jackpot patterns displayed on the second special pattern display section 22b as the game result of the second special game, 25 types of jackpot patterns are classified as Za patterns, 55 types of jackpot patterns are classified as Zb patterns, and 20 types of jackpot patterns are classified as Zc patterns.

[0268] As shown in Fig. 12, for each jackpot game, distribution control information indicating the control contents of the distribution member 38 is set. In the jackpot game based on the symbols Za and Zb, the start condition of the long distribution control is established when the number of game balls detected by the special winning sensor SE3 in the operating round game becomes "2". On the other hand, in the jackpot game based on the symbols ZA and Zc, the start condition of the long distribution control is not established in the operating round game.

[0269] In addition, in the jackpot game based on the Za and Zb symbols, short distribution control and long distribution control are performed in the first round game. In the jackpot game based on the ZA and Zc symbols, short distribution control is performed in the first round game, but long distribution control is not performed. Therefore, in the jackpot game based on the Za and Zb symbols, at least an operating round game that allows the game ball to pass through the special passing area 36 is performed, while in the jackpot game based on the ZA and Zc symbols, an operating round game that allows the game ball to pass through the special passing area 36 is not performed. In other words, it can be said that the jackpot based on the ZA and Zc is a jackpot that is less likely to be controlled to a high probability state after the jackpot game ends than the jackpot based on the Za and Zb.

[0270] As shown in FIG. 11, when the jackpot lottery is won and a jackpot based on the Zc pattern is determined, the first upper limit number of times is 100 times both when the state is controlled to the high probability state and when the state is controlled to the low probability state after the jackpot game ends. In this way, when the jackpot lottery is won and a jackpot based on the Zc pattern is determined, the first upper limit number of times is the same as the specified number of times controlled to the high probability state. Also, when the jackpot lottery is won in the low base state and a jackpot based on the Zc pattern is determined, the first upper limit number of times is 100 times when the state is controlled to the low probability state after the jackpot game ends.

[0271] On the other hand, if the jackpot lottery is won in the high base state and a jackpot based on the Zc pattern is determined, when the jackpot game is controlled to the low probability state after the jackpot game ends, the first upper limit number of times becomes 597 times, which is greater than 100 times. Also, if the jackpot lottery is won in the high base state and a jackpot based on the Za pattern is determined, when the jackpot game is controlled to the high probability state after the jackpot game ends, the first upper limit number of times becomes 697 times, which is greater than 100 times.

[0272] In the jackpot game based on the symbols ZA and Zc, since it is difficult for the game ball to pass through the special passing area 36, ​​there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends. On the other hand, in the jackpot game based on the symbols Za and Zb, since it is easy for the game ball to pass through the special passing area 36, ​​there is a high possibility that the game will be controlled to a high probability state after the jackpot game ends. In particular, among the jackpot games based on the symbols Za to Zc, the jackpot game based on the symbol Zc has a short total opening time of the special variable member 32 in one jackpot game, and furthermore, it can be said to be a jackpot game in which it is difficult for the game ball to pass through the special passing area 36. For this reason, when the jackpot lottery is won in a high base state and a jackpot based on the symbol Zc is determined, the first upper limit number of times is greater than in other cases. For this reason, when a jackpot based on the symbol Zc is determined in a high base state, the first upper limit number of times is greater than in other cases.

[0273] In this way, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on the symbol Zc occurs in the high base state and when it is not. Also, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on the symbol Zc occurs in the high base state and when it is controlled to a low probability state and when it is controlled to a high probability state.

[0274] In particular, when a jackpot based on the symbol Zc occurs in the high base state, if the jackpot game is ended and the game is controlled to the high probability state and the first high base state, the 1st to 697th special games are controlled to the first high base state, the 698th special game is controlled to the low base state, and the 699th to 1458th special games are controlled to the second high base state. When a jackpot based on the symbol Zc occurs in the high base state and the game is controlled to the low probability state and the first high base state after the jackpot game is ended, the 1st to 597th special games are controlled to the first high base state, the 598th special game is controlled to the low base state, and the 599th to 1358th special games are controlled to the second high base state. In this way, when a jackpot based on the symbol Zc occurs in the high base state and the game is controlled to the first high base state after the jackpot game is ended, the number of times the special game is executed from the low base state to the second high base state is one. On the other hand, in other cases, it will be 498 or 598 times.

[0275] In other words, when the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times that the special game is executed from the control to the low base state to the control to the second high base state is smaller when a jackpot based on the symbol Zc occurs in the high base state than otherwise. In particular, when a jackpot based on the symbol Zc occurs in the high base state and the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times that the special game is executed from the control to the low base state to the control to the second high base state is smaller than the first upper limit number of times, and in particular smaller than the reserved upper limit number of each special game.

[0276] In this embodiment, when comparing the total opening time of the special variable member 32 during one jackpot game, the possibility of being controlled to a high probability state after the jackpot game ends, and the number of times the special game is executed in which the special game is controlled to a high base state after the jackpot game ends, it can be said that the second special game is a more advantageous special game for the player than the first special game.

[0277] In this embodiment, when the second special game is executed in the high base state and a jackpot based on the symbol Zc is won, the upper limit number of rounds is small, and there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends, in which case the game progresses in a disadvantageous manner for the player. On the other hand, after the jackpot game ends, it is possible to control to the first high base state and the second high base state, even though it spans one special game, and the degree of advantage for the player can be improved.

[0278] In this embodiment, the jackpot based on the symbol Zc corresponds to the specific jackpot and the second jackpot. In this embodiment, when the jackpot based on the symbol Zc occurs in a high base state, the first condition that is established after the jackpot game based on the symbol Zc ends corresponds to the first special condition, and when the jackpot based on the symbol Zc occurs in a low base state, the first condition that is established after the jackpot game based on the symbol Zc ends corresponds to the second special condition. In this embodiment, when the jackpot based on the symbol ZA occurs, the first condition that is established after the jackpot game based on the symbol ZA ends corresponds to the first specific condition, and when the jackpot based on the symbol Zc occurs in a high base state, the first condition that is established after the jackpot game based on the symbol Zc ends corresponds to the second specific condition.

[0279] In the jackpot process, when a jackpot based on the symbols Za and Zb is determined, the condition for starting the long distribution control is met when the number of game balls entering the large prize winning port 31 in the first round play as the second operating round play becomes "2". Then, the main control CPU 40a operates the distribution member 38 to take the first distribution state based on the long distribution control. Note that, when a jackpot based on the symbols ZA and Zc is determined, the main control CPU 40a does not perform the long distribution control in the first round play.

[0280] In the game state processing, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Zc, and the game ball has passed through the special passing area 36 during the jackpot game, it specifies "697" as the first upper limit number of times. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Zc, and the game ball has not passed through the special passing area 36 during the jackpot game, it specifies "597" as the first upper limit number of times. In other cases, the main control CPU 40a specifies "100" as the first upper limit number of times.

[0281] In this embodiment, the first upper limit number of times is different between the case where the jackpot lottery is won in the high base state and the jackpot type is determined to be based on the symbol Zc and the other cases. Also, in this embodiment, the first upper limit number of times is different between the case where the jackpot lottery is won in the high base state and the jackpot type is determined to be based on the symbol Zc after the jackpot game ends, when the jackpot lottery is won in the high base state and the jackpot type is determined to be based on the symbol Zc, when the jackpot game ends and the low probability state is controlled and the high probability state is controlled.

[0282] In detail, in this embodiment, when the main control CPU 40a has won a jackpot based on the symbol Zc in the high base state and has controlled to the high probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 697 special games are executed without winning the jackpot lottery. When the main control CPU 40a has won a jackpot based on the symbol Zc in the high base state and has controlled to the low probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 597 special games are executed without winning the jackpot lottery. On the other hand, when the main control CPU 40a has won a jackpot based on the symbols ZA, Za, Zb, or has won a jackpot based on the symbol Zc in the low base state and has controlled to the first high base state, the main control CPU 40a controls to the low base state when 100 special games are executed without winning the jackpot lottery.

[0283] In the game state processing of the sub-control board 41, when the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Zc, and the game ball has passed through the special passing area 36 during the jackpot game, it determines "697" as the first upper limit number of times. When the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Zc, and the game ball has not passed through the special passing area 36 during the jackpot game, it determines "597" as the first upper limit number of times. In other cases, the sub-control CPU 41a determines "100" as the first upper limit number of times.

[0284] The fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the symbols Za and Zb occurs, and the current game state is the first high base state after the jackpot game ends, except for the 100th special game. The fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the symbol Zc occurs in a low base state, and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

[0285] The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols Za and Zb occurs, and the current game state is the first high base state in the 100th special game after the jackpot game ends.The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbol Zc occurs in a low base state, and the current game state is the first high base state in the 100th special game after the jackpot game ends.

[0286] The fluctuation pattern determination table T14 is a table that is referenced when a jackpot based on the symbol Zc occurs in a high base state and the current game state is the first high base state after the jackpot game ends. The fluctuation pattern determination table T14 is a table that is referenced when the current game state is the second high base state.

[0287] In the second embodiment, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Zc, and the game ball has passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "697" as the first upper limit number. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern Zc, and the game ball has not passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "597" as the first upper limit number. In other cases, the main control CPU 40a sets the variation count counter to "100" as the first upper limit number.

[0288] As shown in FIG. 13, in either the case where the machine is controlled to the low base state or the case where the machine is controlled to the high base state, if a jackpot based on the symbols Za and Zb is obtained, the machine transitions to the presentation mode MC after the jackpot game ends. In the case where the machine is controlled to the low base state and a jackpot based on the symbol Zc is obtained, the machine transitions to the presentation mode MC after the jackpot game ends. In the case where the machine is controlled to the high base state and a jackpot based on the symbol Zc is obtained, the machine transitions to the presentation mode MD after the jackpot game ends. In this way, the presentation mode MD can be said to be a presentation mode that is used both when a jackpot based on the symbol Zc is obtained when the machine is controlled to the high base state, and when a special game is executed a special number of times after the machine is controlled to the low probability state.

[0289] In this embodiment, when the sub-control CPU 41a determines that the jackpot is based on the symbol Zc in the high base state, it sets the presentation mode flag to information indicating the presentation mode MD. When the sub-control CPU 41a determines that the jackpot is based on the symbols Za and Zb, or that the jackpot is based on the symbol Zc in the low base state, it sets the presentation mode flag to information indicating the presentation mode MC.

[0290] In this way, the presentation mode MC is a presentation mode that is transitioned to (controlled) when a jackpot based on the symbol Zc occurs in the low base state and the first high base state is entered after the jackpot game ends. In other words, the presentation mode MC is a presentation mode that is controllable continuously in at least a plurality of consecutive special games among the special games from the start to the end of the control to the first high base state after a jackpot based on the symbol Zc occurs in the low base state and the first high base state is entered after the jackpot game ends.

[0291] Presentation mode MD is a presentation mode which is transitioned to (controlled) when a jackpot based on pattern Zc occurs in the high base state and control is exercised to the first high base state after the jackpot game ends, and which can then be continuously controlled in at least a number of consecutive special games among the special games from the start to the end of control to the first high base state.

[0292] As shown in Figures 14(a) and 14(b), in the second embodiment, when a jackpot based on the symbols Za and Zb is generated and the state is controlled to the first high base state after the jackpot game ends, this is the same as in the first embodiment, when a jackpot based on the symbols Zb and Zc is generated and the state is controlled to the first high base state after the jackpot game ends. In the second embodiment, when a jackpot based on the symbol Zc is generated and the state is controlled to the first high base state after the jackpot game ends, this is the same as in the first embodiment, when a jackpot based on the symbol Za is generated and the state is controlled to the first high base state after the jackpot game ends.

[0293] [Third embodiment] Next, a third embodiment of the present invention will be described. In the first embodiment, the jackpot based on the symbol Za is the jackpot of the second special game, and the first upper limit number of times is different depending on whether the jackpot based on the symbol Za occurs in a high base state or in a low base state, but this is not limited to this. In the third embodiment, the first upper limit number of times may be different depending on whether the jackpot of the first special game occurs in a high base state or in a low base state. In the following description, the same reference numerals are used for configurations and control contents similar to those of the first embodiment already described, and duplicate descriptions are omitted or simplified.

[0294] As shown in Fig. 15, in the third embodiment, when the jackpot lottery is won and a jackpot based on the pattern ZA is determined, the first upper limit number of times is 100 times both when the state is controlled to the high probability state and when the state is controlled to the low probability state after the jackpot game ends, except when the jackpot lottery is won and a jackpot based on the pattern ZA is determined. In this way, when the jackpot lottery is won and a jackpot based on the pattern ZA is determined, the first upper limit number of times is the same as the specified number of times controlled to the high probability state. Also, when the jackpot lottery is won in the low base state and a jackpot based on the pattern ZA is determined, the first upper limit number of times is 100 times when the state is controlled to the low probability state after the jackpot game ends.

[0295] On the other hand, if the jackpot lottery is won in the high base state and the jackpot based on the pattern ZA is determined, when the jackpot game is controlled to the low probability state after the jackpot game ends, the first upper limit number of times becomes 597 times, which is greater than 100 times. Also, if the jackpot lottery is won in the high base state and the jackpot based on the pattern ZA is determined, when the jackpot game is controlled to the high probability state after the jackpot game ends, the first upper limit number of times becomes 697 times, which is greater than 100 times.

[0296] In addition, in a jackpot game based on the symbol ZA, since it is difficult for the game ball to pass through the special passing area 36, ​​there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends. In particular, in a jackpot game based on the symbol ZA, the total opening time of the special variable member 32 in one jackpot game is shorter than in a jackpot game based on the symbols Za and Zb, and it can be said that the jackpot game is a jackpot game in which it is difficult for the game ball to pass through the special passing area 36. For this reason, when the jackpot lottery is won in a high base state and a jackpot based on the symbol ZA is determined, the first upper limit number of times is set to a number greater than in other cases. For this reason, when a jackpot based on the symbol ZA is determined in a high base state, the first upper limit number of times is set to a number greater than in other cases.

[0297] In this way, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on the symbol ZA occurs in the high base state and when it is not. Also, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on the symbol ZA occurs in the high base state and when it is controlled to a low probability state and when it is controlled to a high probability state.

[0298] In particular, when a jackpot based on the symbol ZA occurs in the high base state, and when the jackpot game is ended and the game is controlled to the high probability state and the first high base state, the 1st to 697th special games are controlled to the first high base state, the 698th special game is controlled to the low base state, and the 699th to 1458th special games are controlled to the second high base state. When a jackpot based on the symbol ZA occurs in the high base state, and when the jackpot game is ended and the game is controlled to the low probability state and the first high base state, the 1st to 597th special games are controlled to the first high base state, the 598th special game is controlled to the low base state, and the 599th to 1358th special games are controlled to the second high base state. In this way, when a jackpot based on the symbol ZA occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state, the number of times the special game is executed from the time when the jackpot game is ended and the game is controlled to the second high base state is one. On the other hand, in other cases, the number of times is 498 times or 598 times.

[0299] In other words, when the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times that the special game is executed from the control to the low base state to the control to the second high base state is smaller when a jackpot based on the symbol ZA occurs in the high base state than otherwise. In particular, when a jackpot based on the symbol ZA occurs in the high base state and the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times that the special game is executed from the control to the low base state to the control to the second high base state is smaller than the first upper limit number of times, and in particular smaller than the reserved upper limit number of each special game.

[0300] In this embodiment, when comparing the total opening time of the special variable member 32 during one jackpot game, the possibility of being controlled to a high probability state after the jackpot game ends, and the number of times the special game is executed in which the special game is controlled to a high base state after the jackpot game ends, it can be said that the second special game is a more advantageous special game for the player than the first special game.

[0301] In this embodiment, when the first special game is executed and a jackpot based on the symbol ZA is won, the jackpot game has a smaller upper limit number of rounds than the jackpots based on the symbols Za and Zb, and there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends, which will be a disadvantageous game progress for the player. In particular, even if the game is controlled to a high base state, if the execution of the second special game is not suspended and the first special game is executed and a jackpot based on the symbol ZA is won, there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends, which will be a disadvantageous game progress for the player. On the other hand, when the first special game is executed in the high base state and a jackpot based on the symbol ZA is won, after the jackpot game ends, it is possible to control to the first high base state and the second high base state, although it spans one special game, and the degree of advantage for the player can be improved.

[0302] In this embodiment, the jackpot based on the symbol ZA corresponds to the specific jackpot and the first jackpot, and the jackpot based on the symbol Za corresponds to the second jackpot. In this embodiment, when a jackpot based on the symbol ZA occurs in a high base state, the first condition that is established after the jackpot game based on the symbol ZA is completed corresponds to the first special condition, and when a jackpot based on the symbol ZA occurs in a low base state, the first condition that is established after the jackpot game based on the symbol ZA is completed corresponds to the second special condition. In this embodiment, when a jackpot based on the symbol ZA occurs, the first condition that is established after the jackpot game based on the symbol ZA is completed corresponds to the first specific condition, and when a jackpot based on the symbol Za occurs in a high base state, the first condition that is established after the jackpot game based on the symbol Za is completed corresponds to the second specific condition.

[0303] In the game state processing, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern ZA, and the game ball has passed through the special passing area 36 during the jackpot game, it specifies "697" as the first upper limit number of times. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern ZA, and the game ball has not passed through the special passing area 36 during the jackpot game, it specifies "597" as the first upper limit number of times. In other cases, the main control CPU 40a specifies "100" as the first upper limit number of times.

[0304] In this embodiment, the first upper limit number of times is different between the case where the jackpot lottery is won in the high base state and the jackpot type is determined to be based on the symbol ZA, and the other cases. Also, in this embodiment, the first upper limit number of times is different between the case where the jackpot lottery is won in the high base state and the jackpot type is determined to be based on the symbol ZA, and the case where the jackpot game is controlled to the low probability state and the high probability state after the end of the jackpot game.

[0305] In detail, in this embodiment, when the main control CPU40a has won a jackpot based on the symbol ZA in the high base state and has controlled to the high probability state and the first high base state after the jackpot game is completed, the main control CPU40a controls to the low base state when 697 special games are executed without winning the jackpot lottery. When the main control CPU40a has won a jackpot based on the symbol ZA in the high base state and has controlled to the low probability state and the first high base state after the jackpot game is completed, the main control CPU40a controls to the low base state when 597 special games are executed without winning the jackpot lottery. On the other hand, when the main control CPU40a has won a jackpot based on the symbol Za to Zc or has won a jackpot based on the symbol ZA in the low base state and has controlled to the first high base state, the main control CPU40a controls to the low base state when 100 special games are executed without winning the jackpot lottery.

[0306] In the game state processing of the sub-control board 41, when the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern ZA, and the game ball has passed through the special passing area 36 during the jackpot game, it determines "697" as the first upper limit number of times. When the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern ZA, and the game ball has not passed through the special passing area 36 during the jackpot game, it determines "597" as the first upper limit number of times. In other cases, the sub-control CPU 41a determines "100" as the first upper limit number of times.

[0307] The fluctuation pattern determination table T11 is a table that is referenced when a jackpot based on the symbol ZA occurs in a low base state, and after the jackpot game ends, the current game state is the first high base state, except for the 100th special game.

[0308] The fluctuation pattern determination table T12 is a table that is referred to when a jackpot based on the symbols Za to Zc occurs and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

[0309] The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols Za to Zc occurs, and the current game state is the first high base state in the 100th special game after the jackpot game ends.The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols ZA occurs in a low base state, and the current game state is the first high base state in the 100th special game after the jackpot game ends.

[0310] The fluctuation pattern determination table T14 is a table that is referred to when a jackpot based on the symbol ZA occurs in a high base state and the current game state is the first high base state after the jackpot game ends. The fluctuation pattern determination table T14 is a table that is referred to when the current game state is the second high base state.

[0311] In this embodiment, the determination condition of the fluctuation pattern referring to the fluctuation pattern determination table T12 corresponds to the second specific determination condition. In this embodiment, the determination condition of the fluctuation pattern referring to the fluctuation pattern determination table T11 corresponds to the second special determination condition. In this embodiment, the determination condition of the fluctuation pattern referring to the fluctuation pattern determination table T14 corresponds to the first special determination condition and the first specific determination condition.

[0312] When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern ZA, and the game ball has passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "697" as the first upper limit number. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of the jackpot is a jackpot based on the pattern ZA, and the game ball has not passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "597" as the first upper limit number. In other cases, the main control CPU 40a sets the variation count counter to "100" as the first upper limit number.

[0313] As shown in FIG. 16, in either the case where the machine is controlled to the low base state or the case where the machine is controlled to the high base state, if a jackpot based on the symbols Za to Zc is obtained, the machine transitions to the presentation mode MC after the jackpot game ends. If a jackpot based on the symbols ZA is obtained when the machine is controlled to the low base state, the machine transitions to the presentation mode MB after the jackpot game ends. If a jackpot based on the symbols ZA is obtained when the machine is controlled to the high base state, the machine transitions to the presentation mode MD after the jackpot game ends. In this way, the presentation mode MD can be said to be a presentation mode that is used both when a jackpot based on the symbols ZA is obtained when the machine is controlled to the high base state, and when a special game is executed a special number of times after the machine is controlled to the low probability state.

[0314] In this embodiment, when the sub-control CPU41a determines that the jackpot is based on the symbol ZA in the high base state, it sets the presentation mode flag to information indicating the presentation mode MD. When the sub-control CPU41a determines that the jackpot is based on the symbol ZA in the low base state, it sets the presentation mode flag to information indicating the presentation mode MB. When the sub-control CPU41a determines that the jackpot is based on the symbols Za to Zc, it sets the presentation mode flag to information indicating the presentation mode MC.

[0315] In this way, the presentation mode MB is a presentation mode that is transitioned to (controlled) when a jackpot based on the symbol ZA occurs in the low base state and the first high base state is entered after the jackpot game ends. In other words, the presentation mode MB is a presentation mode that is controllable continuously in at least a plurality of consecutive special games among the special games from the start to the end of the control to the first high base state after a jackpot based on the symbol ZA occurs in the low base state and the first high base state is entered after the jackpot game ends.

[0316] Presentation mode MC is a presentation mode which is entered (controlled) when a jackpot based on the patterns Za to Zc occurs and control is exercised over the first high base state after the jackpot game ends, and which can then be continuously controlled in at least a number of consecutive special games among the special games from the start to the end of control over the first high base state.

[0317] The presentation mode MD is a presentation mode which is transitioned to (controlled) when a jackpot based on the pattern ZA occurs in the high base state and control is exercised to the first high base state after the jackpot game ends, and which can then be continuously controlled in at least a number of consecutive special games among the special games from the start to the end of control to the first high base state.

[0318] In this embodiment, presentation mode MA corresponds to the normal presentation mode, presentation mode MB corresponds to the second special presentation mode, presentation mode MC corresponds to the second specific presentation mode, and presentation mode MD corresponds to the first special presentation mode and the first specific presentation mode.

[0319] Here, the game state, the conditions for determining the variation pattern, and the presentation mode will be described in detail with reference to FIG. As shown in FIG. 17(a) and FIG. 17(b), in the third embodiment, when the jackpot is based on the symbols Za to Zc and the state is controlled to the first high base state after the jackpot game ends, it is the same as the first embodiment, when the jackpot is based on the symbols Zb and Zc and the state is controlled to the first high base state after the jackpot game ends. In the third embodiment, when the jackpot is based on the symbol ZA in the low base state and the state is controlled to the first high base state after the jackpot game ends, it is the same as the first embodiment, when the jackpot is based on the symbol ZA and the state is controlled to the first high base state after the jackpot game ends. In the third embodiment, when the jackpot is based on the symbol ZA in the high base state and the state is controlled to the first high base state after the jackpot game ends, it is the same as the first embodiment, when the jackpot is based on the symbol Za in the high base state and the state is controlled to the first high base state after the jackpot game ends.

[0320] As described above in detail, the third embodiment has the following advantages. (42) The second special game is a special game that is more advantageous to the player than the first special game. When a jackpot based on the symbol ZA occurs in the high base state and the system is controlled to the first high base state after the jackpot game ends, the number of times that the special game is executed between the control to the low base state and the control to the second high base state is smaller than when a jackpot based on the symbol Za occurs in the high base state and the system is controlled to the first high base state after the jackpot game ends. Therefore, a bonus can be given to the player for winning the jackpot lottery in the first special game, which is less advantageous to the player than the second special game, and the player's interest in the game can be increased.

[0321] (43) In the high base state, a jackpot based on the symbol ZA is obtained, and the system is controlled to the first high base state after the jackpot game is completed, and then the system is controlled to the low base state when 579 or 679 special games are executed. On the other hand, a jackpot based on the symbol Za is obtained, and the system is controlled to the first high base state after the jackpot game is completed, and then the system is controlled to the low base state when 100 special games are executed. Therefore, when a jackpot based on the symbol ZA is obtained in the high base state, and the system is controlled to the first high base state after the jackpot game is completed, a jackpot based on the symbol Za is obtained, and the system is controllable to the first high base state with a larger number of special games than when the system is controlled to the first high base state after the jackpot game is completed. Therefore, in order to specify the number of special games controlled to the first high base state, attention can be drawn to whether the type of jackpot is a jackpot based on the symbol ZA or a jackpot based on the symbol Za, and interest in the game can be improved.

[0322] [Fourth embodiment] Next, a fourth embodiment of the present invention will be described. In the first to third embodiments, when the low base state is controlled after the first high base state is controlled with 597 or 697 times as the first upper limit number of times, the fluctuation pattern determination table T01 is referred to and the performance mode MA is controlled, but this is not limited to this. In the fourth embodiment, when the low base state is controlled after the first high base state is controlled with 597 or 697 times as the first upper limit number of times, the fluctuation pattern determination table T14 may be referred to. Also, in the fourth embodiment, when the low base state is controlled after the first high base state is controlled with 597 or 697 times as the first upper limit number of times, the performance mode MD may be controlled. In the fourth embodiment, the first embodiment is adopted as a premise configuration, but for example, the second embodiment may be adopted or the third embodiment may be adopted, and the same effect is obtained.

[0323] In the fourth embodiment, a jackpot based on the symbol Za occurs in the high base state, and after the jackpot game ends, the system is controlled to the high probability state and the first high base state, and when the 100th special game ends without winning the jackpot lottery, the system is controlled to the low probability state and the first high base state. Also, after the jackpot game ends, when the 597th special game ends without winning the jackpot lottery, the system is controlled to the low probability state and the low base state, and after the jackpot game ends, when the 598th special game ends without winning the jackpot lottery, the system is controlled to the low probability state and the second high base state.

[0324] In this case, after the end of the jackpot game, in the 598th special game without winning the jackpot lottery, the main control CPU40a refers to the variation pattern determination table T14 to determine the variation pattern. Also, after the end of the jackpot game, in the 598th special game without winning the jackpot lottery, the sub-control CPU41a controls to the presentation mode MD.

[0325] As described above in detail, the fourth embodiment has the following advantages. (44) The fluctuation pattern determination table T14 is a table from when a jackpot based on the symbol Za occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state and then controlled to the low base state, until the game is controlled to the second high base state. Therefore, the fluctuation pattern determination table T14 is a table when a jackpot based on the symbol Za occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state, when the game is then controlled to the low base state, and when the game is then controlled to the second high base state. When a jackpot based on the symbol Za occurs in the high base state, when the jackpot game is ended and the game is ended and the game is ended, the fluctuation pattern can be determined based on the fluctuation pattern determination table T14 in the same way when the jackpot game is ended and the game is ended and the game is ended and the game is ended. Therefore, the presentation effect can be enhanced, and the interest in the game can be improved.

[0326] (45) The presentation mode MD is a presentation mode from when a jackpot based on the Za symbol occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state and then controlled to the low base state, until the game is controlled to the second high base state. Therefore, the presentation mode MD is a presentation mode when a jackpot based on the Za symbol occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state, when the jackpot game is ended and the game is then controlled to the low base state, and when the jackpot game is ended and the game is then controlled to the second high base state. When a jackpot based on the Za symbol occurs in the high base state, the jackpot game can be controlled to the presentation mode MD in the same way when the jackpot game is ended and the game is ended and the game is ended and the game is ended and the game is ended. Therefore, the presentation effect can be enhanced, and the interest in the game can be improved.

[0327] The above embodiment can be embodied in the following other embodiments (alternative examples). In the above embodiment, for example, when a specific jackpot occurs in the high base state, the second entry performance may not be executed when the jackpot game ends and the game is controlled from the low base state to the second high base state. The specific jackpot here corresponds to a jackpot based on the Za symbol in the first embodiment, a jackpot based on the Zc symbol in the second embodiment, and a jackpot based on the ZA symbol in the third embodiment. Also, for example, there may be cases where the first entry performance is not executed.

[0328] In the above embodiment, for example, when a specific jackpot occurs in a high base state, after the jackpot game ends, in the 597th or 697th special game, a fluctuation pattern may be determined based on the fluctuation pattern determination table T13, and a final performance may be executed.

[0329] In the above embodiment, for example, when the first high base state is changed to the low base state after the end of a jackpot game, in the low base state, a notification effect (so-called "countdown effect", "premonition effect") regarding the number of times a special game will be executed until the state is changed to the second high base state may be executed. In particular, for example, when a specific jackpot occurs in the high base state, a notification effect is not executed in the low base state after the end of the jackpot game, but a notification effect may be executed in the low base state after the end of the jackpot game.

[0330] In the above embodiment, for example, after the end of a jackpot game, in the high base state (first high base state and second high base state), a notification effect (so-called "right hit notification effect") that can specify that the game ball will flow down to the right side of the game area 21 may be executed. Also, for example, when a specific jackpot occurs in the high base state, and the game is controlled to the first high base state after the end of the jackpot game, and then controlled to the low base state, in the low base state, a notification effect that can specify that the game ball will flow down to the right side of the game area 21 may be executed, and it is preferable that the notification mode is different.

[0331] In the above embodiment, for example, some or all of the presentation content (presentation mode) of the right-hit notification presentation executed in the first high base state and the second high base state may be different. In the above embodiment, for example, any one of the following may be executed: a notification effect capable of specifying that the game ball will not flow down to the left side of the game area 21, a notification effect capable of specifying that the game ball will flow down to the left side of the game area 21, and a notification effect capable of specifying that the game ball will not flow down to the right side of the game area 21.

[0332] In the above embodiment, the fluctuation pattern determination table T14 is a table in which the miss-reach fluctuation pattern is not determined, but the present invention is not limited to this. For example, the fluctuation pattern determination table T14 may be a table in which the miss-reach fluctuation pattern is determined. In this case, for example, the fluctuation pattern determination table T14 is preferably a table in which the miss-reach fluctuation pattern is determined at a determination probability different from that of the fluctuation pattern determination tables T01, T11, and T12, and may be a table in which the miss-reach fluctuation pattern is determined at a determination probability lower than that of the fluctuation pattern determination tables T01, T11, and T12.

[0333] In the above embodiment, for example, a lottery for determining a miss reach fluctuation pattern and a lottery for determining the fluctuation pattern itself may be performed separately. Also, for example, a first lottery for determining a classification of a fluctuation pattern and a second lottery for determining which fluctuation pattern is selected from the classification of the fluctuation pattern determined by the first lottery may be performed separately.

[0334] In the above embodiment, the fluctuation pattern HP35 is determined in the fluctuation pattern determination table T14 and is determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T11, but this is not limiting. For example, the fluctuation pattern HP35 may be determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T11. For example, the fluctuation pattern HP35 may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T12. For example, the fluctuation pattern HP35 may be determined in another fluctuation pattern determination table, and may not be determined in any table other than the fluctuation pattern determination table T14.

[0335] In the above embodiment, the fluctuation pattern HP53 is determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T14, and as the fluctuation pattern of the first special game in the fluctuation pattern determination table T12, but is not limited thereto. For example, the fluctuation pattern HP53 may be determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T12. For example, the fluctuation pattern HP53 may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T11. For example, the fluctuation pattern HP53 may be determined in another fluctuation pattern determination table, and may not be determined in any table other than the fluctuation pattern determination table T14. For example, the fluctuation pattern HP53 may be determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T14, and may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T14.

[0336] In the above embodiment, the fluctuation pattern HP54 is determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T14, and as the fluctuation pattern of the second special game in the fluctuation pattern determination table T12, but is not limited thereto. For example, the fluctuation pattern HP54 may be determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T12. For example, the fluctuation pattern HP54 may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T11. For example, the fluctuation pattern HP54 may be determined in another fluctuation pattern determination table, and may not be determined in any table other than the fluctuation pattern determination table T14. For example, the fluctuation pattern HP54 may be determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T14, and may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T14.

[0337] In the above embodiment, the fluctuation pattern determination tables T11 and T12 are tables in which a miss-reach fluctuation pattern is determined with a higher determination probability than the fluctuation pattern determination table T01, but this is not limited to the above. For example, the fluctuation pattern determination tables T11 and T12 may be tables in which a miss-reach fluctuation pattern is determined with a higher determination probability than the fluctuation pattern determination table T01, or may be tables in which a miss-reach fluctuation pattern is determined with the same determination probability.

[0338] In the above embodiment, for example, in the first high base state, a fluctuation pattern determination table may be referenced to determine the fluctuation pattern in addition to the fluctuation pattern determination tables T11 to T14, and, for example, any of the fluctuation pattern determination tables T11 to T13 may not be present.

[0339] In the above embodiment, for example, in the first special game controlled to the first high base state, a variation pattern determination table that is not referenced in at least any special game other than the first special game in the first high base state may be referenced.

[0340] In the above embodiment, for example, in the second high base state, any one of a plurality of types of fluctuation pattern determination tables may be referred to to determine the fluctuation pattern. In other words, the fluctuation pattern determination table in the second high base state does not have the fluctuation pattern determination tables T01, T11, and T12, and only needs to have at least the fluctuation pattern determination table T14, and other fluctuation pattern determination tables may also be present.

[0341] In the above embodiment, for example, in the second high base state, one of a plurality of types of miss fluctuation patterns may be determined, and the determination conditions may differ depending on, for example, the number of special reserved items and the type of special game (first special game or second special game).

[0342] In the above embodiment, for example, in the first special game controlled to the second high base state, a fluctuation pattern may be determined by referring to a fluctuation pattern determination table that is not referenced in at least any special game other than the first special game in the second high base state.

[0343] In the above embodiment, for example, in the last special game controlled to the second high base state, a fluctuation pattern may be determined by referring to a fluctuation pattern determination table that is not referenced in at least any special game other than the last special game in the second high base state.

[0344] In the above embodiment, for example, in the first high base state, control may be performed to a presentation mode other than the presentation modes MB to MD, and for example, any of the presentation modes MB and MC may not be present.

[0345] In the above embodiment, for example, in the first special game controlled to the first high base state, the presentation mode may be controlled to a different presentation mode that is not controlled in at least any special game other than the first special game in the first high base state.

[0346] In the above embodiment, for example, in the second high base state, it may be controlled to one of a plurality of types of presentation modes. In other words, the presentation modes in the second high base state do not include presentation modes MB and MC, and may include at least presentation mode MD, and may include other presentation modes.

[0347] In the above embodiment, for example, in the first special game controlled to the second high base state, the presentation mode may be controlled to a different presentation mode that is not controlled in at least any special game other than the first special game in the second high base state.

[0348] In the above embodiment, for example, in the last special game controlled in the second high base state, the presentation mode may be controlled to a different presentation mode that is not controlled in at least any special game other than the last special game in the second high base state.

[0349] In the above embodiment, after being controlled to one of the presentation modes MB to MD in response to the end of a jackpot game and a change in the game state, the presentation modes are continuously controlled over a number of consecutive special games, but this is not limited to the above. For example, after being controlled to one of the presentation modes MB to MD in response to the end of a jackpot game and a change in the game state, the presentation modes may not be continuously controlled over a number of consecutive special games, but may be controlled in one special game, and then may be controlled to a different presentation mode. In particular, after being controlled to one of the presentation modes MB to MD in response to the end of a jackpot game and a change in the game state, the presentation modes may be controlled to another presentation mode even if there is no change in the game state.

[0350] In the above embodiment, the same time is determined as the fluctuation time of the normal game in the first high base state and the second high base state, but this is not limited to this. For example, one of multiple times may be determined with the same probability in the first high base state and the second high base state. In other words, the fluctuation time of the normal game may be determined in the same manner in the first high base state and the second high base state. Also, for example, different times may be determined in the first high base state and the second high base state. Also, for example, a shorter time may be determined more easily in the second high base state than in the first high base state, or a shorter time may be determined more easily in the first high base state than in the second high base state.

[0351] In the above embodiment, for example, regarding the winning probability of the normal winning lottery, in the first high base state, the probability of winning the normal winning lottery may be higher than in the low base state. Also, for example, in the second high base state, the probability of winning the normal winning lottery may be higher than in the low base state. Also, for example, in the first high base state, the probability of winning the normal winning lottery may be higher than in the second high base state, and in the second high base state, the probability of winning the normal winning lottery may be higher than in the first high base state.

[0352] In the above embodiment, the same control may be performed for the normal game and the normal win game, for example, the fluctuation time of the normal game, the determination probability of the fluctuation time of the normal game, the opening mode in the normal win game (upper limit opening time per time, closing time per time, total upper limit opening time, upper limit number of openings per time, upper limit control time of one normal win game), etc. In this case, the trigger for control is different between the first high base state and the second high base state, whether it is the first condition or the second condition.

[0353] In the above embodiment, for example, the opening manner of the normal variable member 30 in the first high base state may be any one of two types, four or more types, or one type. In the above embodiment, for example, the opening manner of the normal variable member 30 in the second high base state may be any one of two or more types.

[0354] In the above embodiment, for example, the opening manner of the normal variable member 30 in the low base state may be any one of two or more types. In the above embodiment, for example, a high base transition lottery may be performed when a special game is executed. This high base transition lottery may be performed when the execution of the special game starts or when the execution of the special game ends. When the main control CPU 40a wins the high base transition lottery, it controls to the high base state. Such a high base state may be a third high base state. In other words, the high base state may include a third high base state that is controlled when a condition is met when a predetermined lottery is won, and the third high base state may be present separately from the second high base state, or the third high base state may be present instead of the second high base state.

[0355] In the above embodiment, for example, the first upper limit number of times does not have to vary depending on at least one of the type of jackpot, the game state when the jackpot lottery is won, and whether the high probability state is set after the jackpot game ends.

[0356] In the above embodiment, the first upper limit number of times was the same number (100 times) as the specified number of times controlled to continue in the high probability state, but this is not limited thereto, and may be, for example, a number larger than the specified number of times (e.g., 120 times) or a number smaller than the specified number of times (e.g., 80 times). In this way, a part or all of the first upper limit number of times determined as 100 times may be changed to at least one of a number larger than the specified number of times and a number smaller than the specified number of times. As a specific example, the first upper limit number of times may be 120 times when a jackpot based on the symbol Zb occurs.

[0357] In the above embodiment, the second upper limit number may be a number larger than, smaller than, or the same as the specified number of times controlled to continue in the high probability state. Also, for example, the second upper limit number may be a number larger than, smaller than, or the same as the reciprocal of the winning probability of the jackpot lottery in the low probability state.

[0358] In the above embodiment, the special number of times may be larger, smaller, or the same as the specified number of times controlled to continue in the high probability state. Also, for example, the special number of times may be larger, smaller, or the same as the reciprocal of the winning probability of the jackpot lottery in the low probability state.

[0359] In the above embodiment, when a specific jackpot is hit in the high base state, the first upper limit number of times is different depending on whether the state is controlled to a high probability state or a low probability state after the end of the jackpot game. However, this is not limited to this, and for example, the first upper limit number of times may be the same. As a specific example, in the first embodiment, when a jackpot based on the symbol Za is hit in the high base state, the first upper limit number of times may be 697 times or 597 times both when the state is controlled to a high probability state and when the state is controlled to a low probability state after the end of the jackpot game. In the second embodiment, when a jackpot based on the symbol Zc is hit in the high base state, the first upper limit number of times may be 697 times or 597 times both when the state is controlled to a high probability state and when the state is controlled to a low probability state after the end of the jackpot game. In the third embodiment, when a jackpot based on the symbol ZA occurs in the high base state, the first upper limit number of times may be 597 or 697 both when the state is controlled to the high probability state and when the state is controlled to the low probability state after the jackpot game ends. In such cases, the variation pattern determination table T14 may be referred to and the presentation mode MD may be controlled until the special game of the first upper limit number of times is executed after the jackpot game ends.

[0360] In the above embodiment, when a specific jackpot occurs in the high base state, the number of times the special game is executed after the jackpot game ends, from when the game is controlled to the low base state until the game is controlled to the second high base state, is smaller than the first reserved upper limit number, the second reserved upper limit number, and the total reserved upper limit number, and is smaller than 100 times, but is not limited to this. For example, the number of times such a special game is executed may be larger than or the same as the first reserved upper limit number and the second reserved upper limit number, may be larger than or the same as the total reserved upper limit number, or may be larger than or the same as 100 times.

[0361] In the above embodiment, for example, the number of times a special game is executed from the time when the game is controlled to the low base state until the time when the game is controlled to the second high base state after the end of a jackpot game may be smaller when a specific jackpot occurs in the low base state than when a specific jackpot occurs in the high base state. For example, the number of times a special game is executed from the time when the game is controlled to the low base state until the time when the game is controlled to the second high base state after the end of a jackpot game may be smaller when a first specific jackpot occurs in the high base state than when a second specific jackpot different from the first specific jackpot occurs in the low base state. For example, the number of times a special game is executed from the time when the game is controlled to the low base state until the time when the game is controlled to the second high base state after the end of a jackpot game may be smaller when a second specific jackpot occurs in the low base state than when a first specific jackpot occurs in the high base state.

[0362] In the above embodiment, for example, the high probability state may be awarded until the next big win game is awarded. Also, for example, a drop lottery may be held, and the main control CPU 40a may control the state to a low probability state when a predetermined control condition is established triggered by winning the drop lottery in the case where the state is controlled to a high probability state after the end of the big win game. In this case, it is not possible to specify whether the state is controlled from the high probability state to the low probability state before a predetermined number of special games are executed, and the state may be controlled to the high probability state even after a predetermined number of special games are executed.

[0363] In the above embodiment, for example, when the number of game balls entering the big prize opening 31 varies depending on the type of jackpot, the distribution member 38 may be operated to take the first distribution state based on the long distribution control.

[0364] In the above embodiment, for example, at least one of the short distribution control and the long distribution control may be triggered when a predetermined time has elapsed, rather than when the number of game balls entering the large prize opening 31 has reached a specified number.

[0365] In the above embodiment, for example, it may be any of the second or subsequent rounds of play, it may be one round of play or multiple rounds of play, it may be consecutive rounds of play or discontinuous rounds of play.

[0366] In the above embodiments, for example, the jackpot in the first special game may include a jackpot through which the gaming ball is likely to pass through the special passing area 36, ​​and such a jackpot may correspond to a specific jackpot. Also, for example, as in the first and third embodiments, the jackpot in the second special game may not include a jackpot through which the gaming ball is unlikely to pass through the special passing area 36, ​​and as in the second embodiment, the jackpot in the second special game may include a jackpot through which the gaming ball is likely to pass through the special passing area 36.

[0367] In the above embodiment, when the game ball passes through the special passing area 36 during the jackpot game, the game ball is controlled to a high probability state after the jackpot game ends. However, this is not limited to the above, and the game ball may be controlled to a high probability state after the jackpot game ends based on the type of jackpot. In this case, the special passing area 36 and the distribution member 38 may not be provided. In addition, in the above embodiment, the jackpot in which the game ball easily passes through the special passing area 36 can be replaced with a jackpot that is controlled to a high probability state after the jackpot game ends (so-called "variable jackpot"). The jackpot in which the game ball does not easily pass through the special passing area 36 can be replaced with a jackpot that is controlled to a low probability state after the jackpot game ends (so-called "non-variable jackpot"). In other words, there may be a jackpot that is controlled to a high probability state after the jackpot game ends and a jackpot that is controlled to a low probability state (not controlled to a high probability state) after the jackpot game ends.

[0368] In the above embodiment, for example, a small win lottery may be held separately from a big win lottery. In the above embodiment, for example, there may be a type of jackpot that results in a low base state after the jackpot game ends.

[0369] In the above embodiment, the second special game is executed with priority over the first special game, but this is not limited to the above. For example, the special games may be executed in the order in which the game balls enter the first starting hole 28 and the second starting hole 29, and for example, the first special game and the second special game may be executed simultaneously.

[0370] In the above embodiment, the main control board 40 and the sub-control board 41 are provided and various functions are mounted, but this is not limited thereto, and for example, the functions of one board may be mounted as the functions of the other board. Also, a means for controlling the performance display device 27 may be provided separately. Also, this is not limited to these two types of boards, and for example, it may be configured as an integrated board, or may be configured as three or more types of boards. As a specific example, the functions of the sub-control board 41 may be divided into an overall control board that performs overall control regarding performance, and a display control board that performs control regarding image display.

[0371] In the above embodiment, the type of jackpot (jackpot game) was specified by the symbol command, but the type of jackpot may be specified by a game start command or other dedicated control command.

[0372] In the above embodiment, various random number information related to the special game may be stored in a memory area provided according to the special reserved number. In this case, every time the special game is executed, the random number information may be shifted and stored in a memory area where the special reserved number is subtracted by "1".

[0373] In the above embodiment, for example, the special variable member 32 may be operated to the open state by a predetermined lottery, and a jackpot game may be awarded when a game ball that entered the big prize winning port 31 passes through a specific passing area (so-called "two-type game machine"). Also, for example, the game machine may be a game machine in which the special variable member 32 is operated to the open state by winning a jackpot lottery in a special game (so-called "one-type two-type mixed game machine"). Also, the game machine may be a game machine in which a jackpot game starts when a game ball enters a predetermined ball entry port (so-called three-type game machine). Also, for example, a high probability state may not be awarded.

[0374] Next, the technical ideas that can be understood from the above embodiment and other examples will be described below. (1) A jackpot type determination means is provided for determining the type of jackpot, and the type of jackpot includes a specific jackpot, and the first special condition is a condition that is established after the jackpot game ends when the jackpot lottery is won in the ball entry rate improvement state and the specific jackpot is determined by the jackpot type determination means, and the second special condition is a condition that is established after the jackpot game ends when the jackpot lottery is won in the non-ball entry rate improvement state and the specific jackpot is determined by the jackpot type determination means.

[0375] (2) The first jackpot is characterized in that it is a jackpot that is less likely to be controlled to the high probability state after the jackpot game ends than the second jackpot, or a jackpot that is not controlled to the high probability state after the jackpot game ends.

[0376] (3) When the game state control means controls the game state to the improved winning rate state based on the establishment of the third special condition, the game state control means controls the game state to the improved winning rate state until a predetermined number of pattern change games are executed without winning the jackpot lottery, regardless of the first number and the second number of times.

[0377] (4) When the game state control means controls the game state to the ball winning rate improvement state based on the establishment of the third specific condition, the game state control means controls the game state to the ball winning rate improvement state until a predetermined number of pattern change games are executed without winning the jackpot lottery, regardless of the first number of times and the second number of times.
