  The operation of BB is ended when the medals are paid out to reach the prescribed number (346 in the present embodiment). The RB is activated when a game that reaches the specified number of times (8 times in the present embodiment) is performed, when there is a winning that reaches the specified number of times (8 times in the present embodiment), or BB The operation ends when either of the operations ends. The bonus end number counter, the possible game number counter, and the possible winning number counter are data for managing whether or not the specified number of times or the specified number of times as a trigger end timing of the bonus has been reached.

  More specifically, numerical values defined by the bonus operation time table are stored in the respective counters, and the subtraction is performed through the operation of the bonus. As a result, the operation of the corresponding bonus is completed on condition that the value of each counter is updated to “0”.

[Internal lottery table]
The internal lottery table will be described with reference to FIGS. The internal lottery table defines a data pointer and a lottery value according to the winning number. The data pointer is data acquired as a result of lottery performed with reference to the internal lottery table, and is data for designating an internal winning combination defined by an internal winning combination determination table described later. The data pointer is provided with a small role / replay data pointer and a bonus data pointer.

  In the present embodiment, random numbers extracted from a predetermined numerical range “0 to 65535” are sequentially subtracted by lottery values corresponding to each winning number, and whether or not the result of the subtraction is negative ( An internal lottery is performed by determining whether or not a so-called “digit” has occurred.

  Therefore, the larger the numerical value defined as the lottery value, the higher the probability that the data (that is, the data pointer) to which it is assigned will be determined. The winning probability of each winning number can be represented by “the lottery value corresponding to each winning number / the number of all random numbers that may be extracted (65536)”.

  FIG. 9 shows an internal lottery table for a general gaming state. FIG. 10 shows an internal lottery table for RB operation. In the present embodiment, depending on the situation such as whether or not the bonus is activated, the type of internal winning combination and the winning probability that are determined are varied by using different types of internal lottery tables. , The expectation that the player holds is undulating.

[Internal winning combination determination table]
The internal winning combination determination table will be described with reference to FIGS. The internal winning combination determination table defines an internal winning combination in accordance with the data pointer. When the data pointer is determined, the internal winning combination is uniquely acquired.

  The internal winning combination is data for identifying a combination of symbols of each reel 3L, 3C, 3L that is permitted to be displayed along the winning determination line. Like the display combination, the internal winning combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. When the data pointer is “0”, the content of the internal winning combination is “lost”, which indicates that any display of symbol combinations defined by the symbol combination table described above is not permitted.

  FIG. 11 shows an internal winning combination determination table for a small combination / replay. The small winning combination / replay internal winning combination determination table defines an internal winning combination relating to the payout of medals or an internal winning combination relating to the operation of replay. FIG. 12 shows a bonus internal winning combination determination table. The bonus internal winning combination determination table defines internal winning combinations related to the operation of the bonus.

[Auxiliary flag determination table]
The auxiliary flag determination table will be described with reference to FIGS. The auxiliary flag determination table includes auxiliary flag information according to the lottery value. The auxiliary flag determination table is referred to when determining an auxiliary flag in an auxiliary flag determination process (see FIG. 22) described later.

  The auxiliary flag determination table 1 (see FIG. 13) is referred to when BB is determined as an internal winning combination in an auxiliary flag determination process (see FIG. 22) described later. The auxiliary flag determination table 2 (see FIG. 14) is referred to when the BB is not determined as an internal winning combination in an auxiliary flag determination process (see FIG. 22) described later.

  The auxiliary flag determination table 1 in FIG. 13 and the auxiliary flag determination table 2 in FIG. 14 are defined so that the probability that the auxiliary flag is turned on or off is different. The auxiliary flag is rotated in the middle reel 3C and the right reel 3R according to whether the auxiliary flag is turned on or off in the middle reel rotation start process (see FIG. 23) and the right reel rotation start process (see FIG. 24), which will be described later. Referenced when controlling the start timing.

  In the present embodiment, random numbers extracted from a predetermined numerical range “0 to 1023” are sequentially subtracted by lottery values corresponding to ON and OFF of the auxiliary flag, and the result of the subtraction is negative. A lottery is performed by determining whether or not.

  Here, among the lottery values defined in the auxiliary flag determination table 1 (see FIG. 13), the lottery value corresponding to the auxiliary flag “ON” is “1020”, and the lottery value corresponding to the auxiliary flag “OFF”. Is “4”. For this reason, when BB is determined as an internal winning combination, the auxiliary flag is set on with a probability of 255/256. Of the lottery values defined in the auxiliary flag determination table 2 (see FIG. 14), the lottery value corresponding to the auxiliary flag “on” is “4”, and the lottery value corresponding to the auxiliary flag “off” is “1020”. For this reason, when BB is not determined as an internal winning combination, the auxiliary flag is set to ON with a probability of 1/256.

  Therefore, when the auxiliary flag is determined by lottery with reference to the auxiliary flag determination table 1 (see FIG. 13) referred to when BB is determined as an internal winning combination, BB is determined as an internal winning combination. The auxiliary flag determination table 2 (see FIG. 14) that is referred to when the auxiliary flag is not determined is determined so that the probability that the auxiliary flag is determined to be determined by lottery is higher than when the auxiliary flag is determined by lottery. doing. For this reason, when BB is determined as an internal winning combination, a rotation start effect described later is performed with a probability of 99% or more.

The reel symbol position determination table will be described with reference to FIG. This reel symbol position determination table is a “revolution” described later that is performed when the auxiliary flag is on in a later-described middle reel rotation start process (see FIG. 23) and a later-described right reel rotation start process (see FIG. 24). It is referred to in the case of “start effect”, and is referred to when the rotation start positions of the middle reel 3C and the right reel 3R are determined. The reel symbol position determination table includes lottery value information for determining the symbol symbol number of the reels 3L, 3C, and 3R corresponding to the reel symbol position number and the effect contents. In the present embodiment, random numbers extracted from a predetermined numerical value range “0-32767” are sequentially subtracted by a lottery value corresponding to each reel symbol position number, and whether or not the result of the subtraction becomes negative An internal lottery is performed by determining whether or not a so-called “digit” has occurred.

  The “symbol position number” refers to the symbol position of each rotating reel 3L, 3C, 3R on the center line 8c. The reel symbol position determination table is provided in order to make the display mode of the reels 3L, 3C, and 3R that are rotating in the display windows 21L, 21C, and 21R have the effect contents corresponding to the effect contents.

  The symbol position of the rotating left reel 3L on the center line 8c is “19”, the symbol position of the rotating middle reel 3C on the center line 8c is “0”, and the symbol position of the rotating left reel 3L is rotating on the center line 8c. When the symbol position of the right reel 3R is “19”, the display mode of the rotating reels 3L, 3C, 3R in the display windows 21L, 21C, 21R is 7V. The production content in this case is “7V”.

  Similarly, the symbol position of the rotating left reel 3L on the center line 8c is “0”, the symbol position of the rotating middle reel 3C on the center line 8c is “19”, and the symbol position on the center line 8c is When the symbol position of the rotating right reel 3R is “0”, the display mode of the rotating reels 3L, 3C, 3R in the display windows 21L, 21C, 21R is 7 reverse V-shaped. The production content in this case is “7 reverse V-shaped”.

First, with reference to FIG. 19, the main flowchart by control of the main CPU31 is demonstrated. When power is turned on to the pachi-slot 1, first, the main CPU 31 performs an initialization process (S1). Next, the main CPU 31 clears the designated storage area in the main RAM 33 (S2). In this process, for example, data stored in a storage area that needs to be erased for each game, such as an internal winning combination storage area (see FIG. 16) or a display combination storage area (see FIG. 16), is cleared. .

  Next, the main CPU 31 performs a medal acceptance / start check process which will be described later with reference to FIG. 20 (S3). In this processing, input checks of the medal sensor 42S and the start switch 6S are performed.

  Next, the main CPU 31 extracts a random value and stores it in a random value storage area provided in the main RAM 33 (S4). Next, the main CPU 31 performs an internal lottery process which will be described later with reference to FIG. 21 (S5). In this process, the internal winning combination is determined by lottery based on a random value. Next, the main CPU 31 transmits a start command to the sub-control circuit 72 (S6). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 31 performs auxiliary flag determination processing which will be described later with reference to FIG. 22 (S7). In this process, a process of determining an auxiliary flag with different lottery probabilities depending on whether BB is determined as an internal winning combination or the like is performed.

  Next, the main CPU 31 performs a middle reel rotation start process which will be described later with reference to FIG. 23 (S8). In this process, a process of determining the rotation start timing of the middle reel 3C, etc., is performed when the auxiliary flag is on. Next, the main CPU 31 performs a right reel rotation start process which will be described later with reference to FIG. 24 (S9). In this process, the process of determining the rotation start timing of the right reel 3R, etc., is performed when the auxiliary flag is on.

  When the rotation of each reel 3L, 3C, 3R is requested, the stepping motors 49L, 49C, 49R are driven by an interrupt process (see FIG. 28 described later) executed at a constant cycle (1.1173 msec). Is controlled, and the reels 3L, 3C, 3R start to rotate.

  Next, the main CPU 31 performs a reel stop control process which will be described later with reference to FIG. 25 (S10). In this process, the input of the stop switch 7S is checked, and the rotation of the corresponding reel is stopped based on the timing when the stop button is pressed and the internal winning combination.

  Next, the main CPU 31 searches for a combination of symbols displayed along the winning determination line, and determines a payout number or the like based on the result (S11). As a result of the search, when the symbol combination displayed along the winning determination line matches the symbol combination defined by the symbol combination table (see FIG. 7), the corresponding display combination and the number of payouts are determined. Next, the main CPU 31 transmits a display command to the sub-control circuit 72 (S12). The display command includes parameters that specify the display combination, the number of payouts, and the like.

  Next, the main CPU 31 performs medal payout processing (S13). In this process, the hopper 40 is driven and the number of credits is updated based on the determined payout number. Next, the main CPU 31 updates the bonus end number counter based on the payout number (S14). In this process, the numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 31 determines whether or not the bonus operating flag is on (S15). When determining that the bonus operating flag is on, the main CPU 31 performs a bonus end check process described later with reference to FIG. 27 (S16). In this process, it is checked whether or not to end the operation of the bonus with reference to various counters for managing the end timing of the bonus.

  The main CPU 31 performs a bonus operation check process described later with reference to FIG. 26 after S16 or when it is determined in S15 that the bonus operating flag is not on (S17). In this process, it is checked whether or not the bonus operation is started. When this process ends, the process proceeds to S2.

[Medal reception / start check processing]
Next, with reference to FIG. 20, the medal acceptance / start check process will be described. First, the main CPU 31 determines whether or not the automatic insertion number counter is 0 (S31). When it is determined that the automatic insertion number counter is 0, the medal passage permission is performed (S32). In this process, the solenoid of the selector 42 is driven, and the passage of medals in the selector 42 is prompted.

  When determining that the automatic insertion number counter is not 0, the main CPU 31 copies the automatic insertion number counter to the insertion number counter (S33). Next, the main CPU 31 clears the automatic insertion number counter (S34). S33 and S34 are processes for replaying.

  After S32 or S34, the main CPU 31 sets 3 as the maximum value of the insertion number counter (S35). Next, the main CPU 31 determines whether or not the bonus operating flag is on (S36). When determining that the bonus operating flag is on, the main CPU 31 changes the maximum value of the insertion number counter (S37). In this process, for example, the maximum value is changed to 2.

  The main CPU 31 determines whether or not the passage of medals has been detected after S37 or when it is determined in S36 that the bonus operating flag is not on (S38). When determining that the passage of medals has been detected, the main CPU 31 determines whether or not the inserted number counter has reached the maximum value (S39). When determining that the inserted number counter has not reached the maximum value, the main CPU 31 adds 1 to the inserted number counter (S40). Next, the main CPU 31 transmits a medal insertion command to the sub control circuit 72 (S41). The medal insertion command includes a parameter for specifying the number of inserted coins.

  When the main CPU 31 determines in S39 that the inserted number counter is the maximum value, the main CPU 31 adds 1 to the credit counter (S42). The main CPU 31 checks the bet switch 11S after S42, after S41, or when it is determined that the passage of medals is not detected in S38 (S43). In this process, a numerical value corresponding to the bet button 11 is added to the inserted number counter while being subtracted from the credit counter.

  Next, the main CPU 31 determines whether or not the insertion number counter has reached the maximum value (S44). When it is determined that the insertion number counter has not reached the maximum value, the process proceeds to S38, whereas when it is determined that the insertion number counter has reached the maximum value, it is determined whether or not the start switch 6S is on (S45). ).

  When determining that the start switch 6S is not on, the main CPU 31 proceeds to S38, whereas when determining that the start switch 6S is on, the main CPU 31 prohibits medal passage (S46). In this process, the solenoid of the selector 42 is not driven, and medals are expelled. When this process ends, the medal acceptance / start check process ends.

[Internal lottery processing]
Next, an internal lottery process will be described with reference to FIG. First, the main CPU 31 determines an internal lottery table (see FIGS. 9 and 10) and the number of lotteries (S61). The operating flag storage area (see FIG. 18) is referred to, and the internal lottery table and the number of lotteries are determined according to whether or not the bonus is activated. The number of lotteries indicates the number of times that a lottery value is subtracted and a determination is made as to whether a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 31 obtains a random value stored in the random value storage area and sets it as a determination random value (S62). Next, the main CPU 31 sets 1 as the initial value of the winning number (S63).

  Next, the main CPU 31 refers to the internal lottery table and acquires a lottery value corresponding to the winning number (S64). Next, the main CPU 31 subtracts the lottery value from the determination random number value (S65). Next, the main CPU 31 determines whether or not a digit has been made (S66). When the main CPU 31 determines that the digit is not performed, the main CPU 31 subtracts 1 from the number of lotteries and adds 1 to the winning number (S67).

  Next, the main CPU 31 determines whether or not the number of lotteries is 0 (S68). When the main CPU 31 determines that the number of lotteries is not 0, the process proceeds to S64. On the other hand, when the number of lotteries is determined to be 0, the main CPU 31 sets 0 as the small role / replay data pointer and serves as the bonus data pointer. 0 is set (S69).

  When the main CPU 31 determines in S66 that a digit has been made, the main CPU 31 obtains a small role / replay data pointer and a bonus data pointer according to the current winning number (S70). After S70 or S69, the main CPU 31 refers to the small winning combination / replay internal winning combination determination table (see FIG. 11), and acquires the internal winning combination based on the small winning combination / replay data pointer (S71).

  Next, the main CPU 31 stores the acquired internal winning combination in the internal winning combination storing area (see FIG. 16) (S72). Next, the main CPU 31 determines whether or not the data stored in the carryover combination storage area (see FIG. 17) is 0 (S73). When the main CPU 31 determines that the data stored in the carryover combination storage area is 0, the main CPU 31 refers to the bonus internal winning combination determination table (see FIG. 12), and determines the internal winning combination based on the bonus data pointer. Is acquired (S74). Next, the main CPU 31 stores the acquired internal winning combination in the carryover combination storing area (S75).

  When the main CPU 31 determines that the data stored in the carryover combination storage area (see FIG. 17) is not 0 after S75 or in S73, the carryover combination storage area and the internal winning combination storage area (see FIG. 16). And the result is stored in the internal winning combination storing area (S76). That is, the internal winning combination relating to the bonus operation is carried over. When this process ends, the internal lottery process ends.

[Auxiliary flag decision processing]
Next, the auxiliary flag determination process will be described with reference to FIG. First, the main CPU 31 determines whether or not BB is determined as an internal winning combination (S81). When determining that BB has been determined as an internal winning combination, the main CPU 31 determines an auxiliary flag by lottery based on the auxiliary flag determination table 1 (see FIG. 13) (S82). When determining that the BB is not determined as the internal winning combination, the main CPU 31 determines the auxiliary flag by lottery based on the auxiliary flag determination table 2 (see FIG. 14) (S83).

  The main CPU 31 determines whether or not the auxiliary flag is on after S83 or after S82 (S84). When the main CPU 31 determines that the auxiliary flag is not on, the main CPU 31 ends the auxiliary flag determination process. On the other hand, when the main CPU 31 determines that the auxiliary flag is on, the main CPU 31 determines the reel based on the reel symbol position determination table (see FIG. 15). The symbol position number is determined by lottery (S85). When this process ends, the auxiliary flag determination process ends.

[Medium reel rotation start processing]
Next, the middle reel rotation start process will be described with reference to FIG. First, the main CPU 31 determines whether or not the auxiliary flag is on (S91). When determining that the auxiliary flag is not on, the main CPU 31 requests rotation start of all the reels 3L, 3C, 3R (S92). When this process ends, the middle reel rotation start process ends.

  When determining that the auxiliary flag is on in S91, the main CPU 31 requests the left reel 3C to start rotating (S93). Next, the main CPU 31 refers to the reel symbol position determination table (see FIG. 15) and determines the symbol position number LX of the left reel and the symbol position number CX of the middle reel corresponding to the determined reel symbol position number. (S94). Next, the main CPU 31 determines a symbol position number CY on the center line 8c in the stopped middle reel 3C (S95).

  Next, the main CPU 31 determines whether or not the value of the symbol position number CX of the middle reel is greater than or equal to the value of the symbol position number CY on the center line 8c in the stopped middle reel 3C (S96). When the main CPU 31 determines that the value of the symbol position number CX of the middle reel is greater than or equal to the value of the symbol position number CY on the center line 8c in the stopped middle reel 3C, the value of the symbol position number CX of the middle reel Then, a value obtained by subtracting the value of the symbol position number CY on the center line 8c in the stopped middle reel 3C is stored in the difference counter as a difference D1. (S97).

  When the main CPU 31 determines in S96 that the value of the symbol position number CX of the middle reel is not equal to or greater than the value of the symbol position number CY on the center line 8c in the stopped middle reel 3C, the symbol position number of the middle reel. A value obtained by adding 21 to the value obtained by subtracting the value of the symbol position number CY on the center line 8c in the stopped middle reel 3C from the CX value is stored in the difference counter as a difference D1. (S98).

  The main CPU 31 subtracts the value of the difference D1 stored in the difference counter from the value of the symbol position number LX of the left reel corresponding to the determined reel symbol position number after S98 or S97. It is determined whether or not it is smaller than 0 (S99).

  The main CPU 31 determines when the value obtained by subtracting the value of the difference D1 stored in the difference counter from the value of the symbol position number LX of the left reel corresponding to the determined reel symbol position number is 0 or more. A value obtained by subtracting the value of the difference D1 stored in the difference counter from the value of the symbol position number LX of the left reel corresponding to the reel symbol position number is stored in the rotation start symbol position number counter as the middle reel rotation start symbol position number M1. (S100).

  The main CPU 31 determines that the value obtained by subtracting the value of the difference D1 stored in the difference counter from the value of the symbol position number LX of the left reel corresponding to the determined reel symbol position number is smaller than 0. The rotation start symbol is set to a value obtained by adding 21 to the value obtained by subtracting the value of the difference D1 stored in the difference counter from the value of the symbol position number LX of the left reel corresponding to the reel symbol position number as the middle reel rotation start symbol position number M1. Store in the position number counter (S101).

  The main CPU 31 determines the symbol position number LZ on the center line 8c in the rotating left reel 3L after S101 or after S100 (S102). Next, the main CPU 31 determines whether or not the value of the middle reel rotation start symbol position number M1 is the same as the value of the symbol position number LZ on the center line 8c in the rotating left reel 3L (S103). .

  When the main CPU 31 determines that the value of the symbol position number M1 for starting the rotation of the middle reel is not the same as the value of the symbol position number LZ on the center line 8c in the rotating left reel 3L, the process proceeds to S102. When it is determined that the value of the middle reel rotation start symbol position number M1 is the same as the value of the symbol position number LZ on the center line 8c in the rotating left reel 3L, the rotation start of the middle reel 3C is requested ( S104). Next, the main CPU 31 clears the difference counter (S105). When this process ends, the middle reel rotation start process ends. The difference counter and the rotation start symbol position number counter are provided in a predetermined area of the main RAM of the main control circuit 71.

[Right reel rotation start processing]
Next, the right reel rotation start process will be described with reference to FIG. First, the main CPU 31 determines whether or not the auxiliary flag is on (S111). When determining that the auxiliary flag is not turned on, the main CPU 31 ends the right reel rotation start process. On the other hand, when determining that the auxiliary flag is turned on, the main CPU 31 refers to the reel symbol position determination table (see FIG. 15). Then, the symbol position number CX of the middle reel and the symbol position number RX of the right reel corresponding to the determined reel symbol position number are determined (S112). Next, the main CPU 31 determines a symbol position number RY on the center line 8c in the stopped right reel 3R (S113).

  Next, the main CPU 31 determines whether or not the value of the symbol position number RX of the right reel is equal to or greater than the value of the symbol position number RY on the center line 8c in the stopped right reel 3R (S114). When the main CPU 31 determines that the value of the symbol position number RX of the right reel is greater than or equal to the value of the symbol position number RY on the center line 8c in the stopped right reel 3R, the value of the symbol position number RX of the right reel The value obtained by subtracting the value of the symbol position number RY on the center line 8c in the stopped right reel 3R is stored in the difference counter as a difference D2. (S115).

  When the main CPU 31 determines in S114 that the value of the symbol position number RX of the right reel is not equal to or greater than the value of the symbol position number RY on the center line 8c in the stopped right reel 3R, the symbol position number of the right reel A value obtained by adding 21 to the value obtained by subtracting the value of the symbol position number RY on the center line 8c in the stopped right reel 3R from the value of RX is stored in the difference counter as a difference D2. (S116).

  The main CPU 31 subtracts the value of the difference D2 stored in the difference counter from the value of the symbol position number CX of the middle reel corresponding to the determined reel symbol position number after S116 or S115. It is determined whether it is smaller than 0 (S117).

  The main CPU 31 determines when the value obtained by subtracting the value of the difference D2 stored in the difference counter from the value of the symbol position number CX of the middle reel corresponding to the determined reel symbol position number is 0 or more. A value obtained by subtracting the value of the difference D2 stored in the difference counter from the value of the symbol position number CX of the middle reel corresponding to the reel symbol position number is stored in the rotation start symbol position number counter as the right reel rotation start symbol position number M2. (S118).

  The main CPU 31 determines that the value obtained by subtracting the value of the difference D2 stored in the difference counter from the value of the symbol position number CX of the middle reel corresponding to the determined reel symbol position number is smaller than 0. The rotation start symbol is set as a value obtained by adding 21 to the value obtained by subtracting the value of the difference D2 stored in the difference counter from the value of the symbol position number CX of the middle reel corresponding to the reel symbol position number as the right reel rotation start symbol position number M2. Store in the position number counter (S119).

  After S119 or after S118, the main CPU 31 determines the symbol position number CZ on the center line 8c in the rotating middle reel 3C (S120). Next, the main CPU 31 determines whether or not the value of the right reel rotation start symbol position number M2 is the same as the value of the symbol position number CZ on the center line 8c in the rotating middle reel 3C (S121). .

  When the main CPU 31 determines that the value of the right reel rotation start symbol position number M2 is not the same as the value of the symbol position number CZ on the center line 8c in the rotating middle reel 3C, the process proceeds to S120. When it is determined that the value of the right reel rotation start symbol position number M2 is the same as the value of the symbol position number CZ on the center line 8c in the rotating middle reel 3C, the rotation start of the right reel 3R is requested ( S122). Next, the main CPU 31 clears the difference counter (S123). Next, the main CPU 31 clears the auxiliary flag (S124). When this process ends, the right reel rotation start process ends.

[Reel stop control process]
Next, the reel stop control process will be described with reference to FIG. First, the main CPU 31 determines whether or not a valid stop button has been pressed (S131). When the main CPU 31 determines that a valid stop button has not been pressed, it waits until it is pressed.

  When determining that a valid stop button has been pressed, the main CPU 31 invalidates the operation of the corresponding stop button (S132). The valid and invalid states of the stop buttons 7L, 7C, and 7R are managed in a predetermined storage area provided in the main RAM 33.

  Next, the main CPU 31 sets 5 as the number of checks (S133). In the present embodiment, since the maximum number of sliding symbols is “4”, when the stop button is pressed, including the symbol position in the middle of the corresponding display window, Up to the position is subject to check. That is, any of the five numerical values “0”, “1”, “2”, “3”, and “4” is determined as the number of sliding frames.

  Next, based on the internal winning combination, the main CPU 31 includes each position within the range of the number of checks including the position of the symbol in the middle of the corresponding display window (hereinafter referred to as the stop start position) when the stop button is pressed. Among the symbol positions, the symbol position with the highest priority is searched (S134). In this process, the position of the symbol that can display the combination of symbols permitted to be displayed by the internal winning combination along the winning determination line is determined as the position of the symbol with the highest priority.

  Next, the main CPU 31 determines the number of sliding symbols based on the search result (S135). The number of symbols from the stop start position to the symbol position with the highest priority is determined as the number of sliding symbols. Next, the main CPU 31 shifts to waiting for a scheduled stop position (S136). When a transition is made to waiting for the planned stop position, the driving of the stepping motors 49L, 49C, 49R is controlled by an interrupt process described later (see FIG. 28 described later), and the position of the symbol with the highest priority reaches the middle stage of the corresponding display window. The reels are stopped from rotating after waiting.

  Next, the main CPU 31 transmits a reel stop command to the sub-control circuit 72 (S137). The reel stop command includes a parameter for specifying the type of the stopped reel.

  Next, the main CPU 31 determines whether or not there is a stop button whose operation is valid (S138). That is, it is determined whether there is a reel that is still rotating. When the main CPU 31 determines that there is a stop button with an effective operation, the main CPU 31 proceeds to S131, whereas when it determines with no stop button with an effective operation, the main CPU 31 ends the reel stop control process.

[Bonus activation check process]
Next, the bonus operation check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the display combination is BB (S141). When the main CPU 31 determines that the display combination is BB, the main CPU 31 refers to the bonus operation time table (see FIG. 8) and performs the BB operation processing (S142). In this process, the BB operating flag is turned on, and a predetermined value is set in the bonus end number counter.

  Next, the main CPU 31 clears the carryover combination storage area (see FIG. 17) (S143). Next, the main CPU 31 transmits a bonus start command to the sub control circuit 72 (S144). When this process ends, the bonus operation check process ends.

  When determining that the display combination is not BB in S141, the main CPU 31 determines whether or not the display combination is replay (S145). When determining that the display combination is replay, the main CPU 31 copies the value of the insertion number counter to the automatic insertion number counter (S146).

  When determining that the display combination is not replay in S145, the main CPU 31 determines whether or not the BB operating flag is on (S147). When determining that the BB operating flag is not on, the main CPU 31 ends the bonus operation check process, whereas when determining that the BB operating flag is on, whether or not the RB operating flag is on. Is determined (S148).

  When the main CPU 31 determines that the RB operating flag is on, the main CPU 31 ends the bonus operation check process. On the other hand, when the main CPU 31 determines that the RB operating flag is not on, the main CPU 31 reads the bonus operating table (see FIG. 8). Referring to FIG. 5, processing at the time of RB operation is performed (S149). In this process, the RB operating flag is turned on, and predetermined values are set in the winning possible number counter and the possible gaming number counter. When this process ends, the bonus operation check process ends.

[Bonus end check process]
Next, the bonus end check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the bonus end number counter is 0 (S151). When determining that the bonus end number counter is 0, the main CPU 31 performs BB end time processing (S152). In this process, the BB operating flag and the RB operating flag are turned off, and various counters for managing the end timing of the bonus are cleared. Next, the main CPU 31 transmits a bonus end command to the sub-control circuit 72 (S153). When this process ends, the bonus end check process ends.

  When the main CPU 31 determines in S151 that the bonus end number counter is not 0, the main CPU 31 updates the winning possible number counter or the possible gaming number counter (S154). In this process, the possible game number counter is decremented by one, and if there is a win, the possible pay number counter is decremented by one. Next, the main CPU 31 determines whether or not the winning possible number counter or the possible gaming number counter is 0 (S155).

  When the main CPU 31 determines that the winning possible number counter or the possible gaming number counter is not 0, the main CPU 31 ends the bonus end check process, while determining that the possible winning number counter or the possible game number counter is 0, Processing at the end of RB is performed (S156). In this process, the RB operating flag is turned off, and the winning possible number counter and the possible gaming number counter are cleared. When this process ends, the bonus end check process ends.

[Interrupt processing under the control of the main CPU (1.1173 msec)]
Next, an interrupt process (1.1173 msec) controlled by the main CPU 31 will be described with reference to FIG. First, the main CPU 31 saves a register (S161). Next, the main CPU 31 performs input port check processing (S162). In this process, signals input from various switches such as the stop switch 7S are checked.

  Next, the main CPU 31 performs a reel control process (S163). In this process, when the start of rotation of all reels 3L, 3C, 3R is requested, the rotation of the reels 3L, 3C, 3R is started, and then the stepping motors 49L, 49C, The drive of 49R is controlled. When the number of sliding pieces is determined, the driving of the stepping motor is controlled so that the rotation of the corresponding reel waits for the number of sliding pieces and the rotation is decelerated and stopped.

  Next, the main CPU 31 performs a lamp and 7-segment drive process (S164). Next, the main CPU 31 restores the register (S165). When this process ends, the interrupt process ends.

[Program flow executed by sub CPU of sub control circuit]
This completes the description of the contents of the program executed by the main CPU 31 of the main control circuit 71. Next, contents of a program executed by the sub CPU 81 of the sub control circuit 72 will be described with reference to FIGS.

[Main board communication task]
With reference to FIG. 29, the main board | substrate communication task performed by sub CPU81 is demonstrated. First, the sub CPU 81 performs reception check of the command transmitted from the main control circuit 71 (S301). Next, when receiving a command, the sub CPU 81 extracts the type of the command (S302).

  Next, the sub CPU 81 determines whether or not a command different from the previous one has been received (S303). If the sub CPU 81 determines that a command different from the previous command has not been received, the process proceeds to S301. On the other hand, if the sub CPU 81 determines that a command different from the previous command has been received, the sub CPU 81 stores the command in the message queue (S304).

[Direction registration task]
Next, an effect registration task performed by the sub CPU 81 will be described with reference to FIG. First, the sub CPU 81 extracts a message from the message queue (S311). Next, the sub CPU 81 determines whether there is a message (S312). When the sub CPU 81 determines that there is a message, it copies the game information from the message (S313). For example, various data such as an internal winning combination, a type of reel that has stopped rotating, a display combination, an operating flag, and the like specified by parameters are copied to a storage area provided in the sub-RAM 83.

  Next, the sub CPU 81 performs an effect content determination process which will be described later with reference to FIG. 31 (S314). In this process, depending on the type of the received command, the contents of the effect are determined and the effect data is registered.

  The sub CPU 81 registers animation data after S314 or when it is determined that there is no message in S312 (S315). Next, the sub CPU 81 registers sound data (S316). Next, the sub CPU 81 registers lamp data (S317). The registration of animation data, the registration of sound data, and the registration of ramp data are performed based on the effect data registered in the effect content determination process (see FIG. 31 described later). When this process ends, the process proceeds to S311.

[Production content decision processing]
Next, with reference to FIG. 31, the flowchart of the effect content determination process performed by sub CPU81 is demonstrated. First, the sub CPU 81 determines whether or not it is a start command reception time (S321). When determining that the start command is received, the sub CPU 81 extracts the effect random number, determines the effect number by lottery based on the internal winning combination, and registers it (S322). The production number is data for designating production contents to be executed this time.

  Next, the sub CPU 81 registers the production data at the start based on the registered production number (S323). The effect data is data that designates animation data, sound data, and lamp data. When the effect data is registered, corresponding animation data and the like are determined, and effects such as video display are executed. When this process ends, the effect content determination process ends.

  Next, when determining that the start command is not received, the sub CPU 81 determines whether or not the reel stop command is received (S324). If the sub CPU 81 determines that the reel stop command is received, the sub CPU 81 registers the stop effect data based on the registered effect number and the type of the operation stop button (S325). The operation stop button is a button that is pressed out of the effective stop buttons. When this process ends, the effect content determination process ends.

  Next, when determining that the reel stop command is not received, the sub CPU 81 determines whether or not the display command is received (S326). When determining that the display command is being received, the sub CPU 81 registers the display effect data based on the registered effect number (S327). When this process ends, the effect content determination process ends.

  Next, when determining that the display command is not received, the sub CPU 81 determines whether or not the bonus start command is received (S328). If the sub CPU 81 determines that the bonus start command has been received, the sub CPU 81 registers the bonus start effect data (S329). When this process ends, the effect content determination process ends.

  Next, when determining that the bonus start command is not received, the sub CPU 81 determines whether or not the bonus end command is received (S330). When the sub CPU 81 determines that the bonus end command is not received, the sub CPU 81 ends the effect content determination process. On the other hand, if the sub CPU 81 determines that the bonus end command is received, the sub CPU 81 registers the bonus end effect data (S331). . When this process ends, the effect content determination process ends.

  Next, the content of the “rotation start effect” performed by the main CPU 31 will be described with reference to the display examples of FIGS.

  32 to 35 show that “1” is determined as the reel symbol position number when the auxiliary flag is turned on by lottery, and “7V character” is determined as the effect content. "Is shown.

  FIG. 32 shows a display example when the auxiliary flag is turned on by lottery and the rotation of the left reel 3L is started. In this case, the rotation of the middle reel 3C and the right reel 3R has not yet started.

  FIG. 33 shows a display example when the rotation of the middle reel 3C starts after the rotation of the left reel 3L. In the embodiment, “cherry” corresponding to the symbol position number “7” is stopped and displayed on the center line 8c of the middle reel 3C that is stopped. First, referring to the reel symbol position determination table (see FIG. 15), the symbol position number LX “19” of the left reel 3L corresponding to the determined reel symbol position number “1” and the symbol position number of the middle reel 3C. CX “0” is determined. Next, the symbol position number CY “7” on the center line 8c in the stopped middle reel 3C is determined.

  The symbol position number CX “0” of the middle reel corresponding to the determined reel symbol position number “1” is determined because it is equal to or smaller than the symbol position number CY “7” on the center line 8c in the stopped middle reel. 21 is obtained by subtracting the symbol position number CY “7” on the center line 8c of the stopped middle reel from the symbol position number CX “0” of the middle reel corresponding to the reel symbol position number “1”. Is stored in the difference counter as a difference D1.

  Since the value “5” obtained by subtracting the difference D1 “14” from the symbol position number LX “19” of the left reel corresponding to the determined reel symbol position number “1” is larger than “0”, this determination is made. The rotation start symbol position number counter is obtained by subtracting the difference D1 “14” from the symbol position number LX “19” of the left reel corresponding to the reel symbol position number “1” as a middle reel rotation start symbol position number M1. To store.

  Next, the symbol position number LZ on the center line 8c in the rotating left reel 3L is determined. As a result of the rotation of the left reel 3L, when the symbol position number M1 “5” for starting the middle reel rotation and the symbol position number LZ on the center line 8c in the rotating left reel 3L become the same value, The rotation of the middle reel 3C is started in synchronization with the reel 3L.

  That is, the rotation of the middle reel 3C is started in synchronism with the left reel 3L at the timing when the “replay” corresponding to the symbol position number “5” on the left reel 3L is variably displayed on the center line 8c.

  FIG. 34 shows a display example when the rotation of the right reel 3R starts after the rotation start of the middle reel 3C. In the embodiment, “replay” corresponding to the symbol position number “2” is stopped and displayed on the center line 8c of the stopped right reel 3R. First, referring to the reel symbol position determination table (see FIG. 15), the symbol position number CX “0” of the middle reel corresponding to the determined reel symbol position number “1”, and the symbol position number RX “of the right reel. 19 "is determined. Next, the symbol position number RY “2” on the center line 8c in the stopped right reel 3R is determined.

  Since the symbol position number RX “19” of the right reel corresponding to the determined reel symbol position number “1” is equal to or larger than the symbol position number RY “2” on the center line 8c in the stopped right reel 3R. The value “17” obtained by subtracting the symbol position number RY “2” on the center line 8c of the stopped right reel 3R from the symbol position number RX “19” of the right reel corresponding to the reel symbol position number “1”. The difference D2 is stored in the difference counter.

  The value “−17” obtained by subtracting the difference D2 “17” from the symbol position number CX “0” of the middle reel corresponding to the determined reel symbol position number “1” is smaller than “0”. The value “4” obtained by adding “21” to the value “−17” obtained by subtracting the difference D2 “17” from the symbol position number CX “0” of the middle reel corresponding to the reel symbol position number “1” is set to the right reel. The rotation start symbol position number M2 is stored in the rotation start symbol position number counter.

  Next, the symbol position number CZ on the center line 8c in the rotating middle reel 3C is determined. As a result of the rotation of the middle reel 3C, the right reel rotation start symbol position number M2 “4” and the symbol position number CZ on the center line 8c in the rotating middle reel 3C become the same value. The rotation of the reel 3R is started.

  That is, the rotation of the right reel 3R is started in synchronization with the middle reel 3C at the timing when the “watermelon” corresponding to the symbol position number “4” on the middle reel 3C is variably displayed on the center line 8c.

  In FIG. 35, the middle reel 3C and the right reel 3R start to rotate at the determined timing and are synchronized at the same speed as the left reel 3L, and all the reels 3L, 3C, 3R have the same speed. As a result of rotating in a synchronized manner, an example of display in the case where an effect with the effect content “7V” corresponding to the reel symbol position number “1” is made is shown. In the embodiment, the reels 3L, 3C, and 3R that are rotating are rotated synchronously so that the display windows 21L, 21C, and 21R have a “red 7” V shape.

  Therefore, the player has a sense of expectation that BB is determined as an internal winning combination by displaying “7V” in the display windows 21L, 21C, and 21R by the rotating reels 3L, 3C, and 3R. Can have.

  For this reason, when BB is determined as an internal winning combination, the auxiliary flag is turned on, and each symbol indicating “red 7-red 7-red 7”, which is a symbol combination corresponding to BB, is “7V”. Thus, the driving of each reel 3L, 3C, 3R is controlled so as to synchronize.

  Thereby, the player can recognize that BB corresponding to each symbol is determined as an internal winning combination by looking at the symbols of the rotating reels 3L, 3C, 3R. Therefore, the display window 21L, 21C, 21R, which is always visible when the player plays a game, is notified that BB is determined as an internal winning combination, so that the player can display the display window 21L. , 21C, 21R can be played while paying attention only. Thereby, the player can concentrate on the game, and the operating rate of the gaming machine can be increased.

  As mentioned above, although the Example was described, this invention is not limited to this.

  In the above-described embodiment, as a result of the rotation of the left reel 3L, the symbol position number M1 for starting the rotation of the middle reel and the symbol position number LZ on the center line 8c in the rotating left reel 3L become the same value. In addition, although the rotation of the middle reel 3C is started, the present invention is not limited to this. For example, considering the time until the rotation of the middle reel 3C reaches a constant speed, the rotation may be started earlier by a value corresponding to 1 to 5 frames. Similarly, the rotation of the right reel 3R may be started earlier by a value corresponding to 1 to 5 frames in consideration of the time until the rotation of the right reel 3R reaches a constant speed.

  In the above-described embodiment, only when the BB is determined as an internal winning combination, the auxiliary flag is determined to be turned on with reference to the auxiliary flag determination table 1 (see FIG. 13) with a high probability that the auxiliary flag is turned on. However, it is not limited to this. For example, when cherry, bell, watermelon or replay is determined as an internal winning combination, the auxiliary flag is turned on, and the reel symbol position determination table (see FIG. 36) is referred to according to each internal winning combination. The position number may be determined, and the rotation start timing of the middle reel 3C and the right reel 3R may be determined corresponding to the determined reel symbol position number.
