Description

The present invention relates to a gaming machine.

  2. Description of the Related Art Conventionally, a gaming machine including a plurality of reels each having a plurality of symbols arranged on each surface, a start switch, a stop switch, and a control unit is known. The start switch detects that the start lever has been operated by the player (hereinafter referred to as “start operation”) on condition that a game medium such as a game medal or coin (hereinafter referred to as a medal) has been inserted, A signal requesting the start of rotation of all reels is output. The stop switch detects that the stop button provided corresponding to each of the plurality of reels has been pressed by the player (hereinafter referred to as “stop operation”), and requests to stop the rotation of the corresponding reel. Is output. A driving force of a stepping motor provided corresponding to each of the reels is transmitted to the plurality of reels. The control unit controls the operation of the stepping motor based on the signals output from the start switch and the stop switch, and rotates and stops each reel.

  In such a gaming machine, when a start operation is detected, a lottery process using random numbers on the program (hereinafter referred to as “internal lottery process”) is performed, and the result of the lottery (hereinafter referred to as “internal winning combination”) and stoppage are stopped. The reel rotation is stopped based on the operation timing. As a result of stopping the rotation of all the reels, when a symbol combination related to the winning is displayed, a privilege associated with the symbol combination is given to the player.

  As a privilege given to the player, the chances of paying out game media (medals, etc.), re-games in which internal lottery processing is performed without consuming the game media next time, and payout of game media are increased. The operation of a bonus game can be mentioned.

In recent years, a special game (so-called “MB”) in which all the small roles related to payout of game media are determined as internal winning combinations and a game in which stop control for some reels is uncontrolled can be performed for a predetermined period of time. A gaming machine provided is known (Patent Document 1). In this special game, since some reels are stopped based on the player's stop operation, the player's intention can be reflected in the displayed symbol combination, and the game's interest can be enhanced.
JP 2007-117497 A

  However, the conventional special game (MB) ends when the total number of game media paid out reaches a predetermined number or when a predetermined internal winning combination is won. For this reason, the game media obtained are approximately constant even though there may be some difference depending on the number of game media inserted. Therefore, even if the player's intention is reflected in the displayed symbol combination, the game may become monotonous.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a gaming machine that can enhance the interest of a game by changing the number of game media that can be acquired in a special game (MB). .

  In order to achieve the above object, the present invention provides the following gaming machines.

Insertion operation detection means (for example, a medal sensor 35S and a bet switch 12S, which will be described later) for detecting a game medium input operation
Start operation detecting means (for example, a start switch 16S described later) for detecting a start operation based on detection of the input operation by the input operation detecting means;
Fluctuation display means (for example, three reels 3L, 3C, 3R and a stepping motor 61L described later), which is composed of a plurality of display rows and variably displays symbols necessary for the game based on detection of the start operation by the start operation detection means. , 61C, 61R)
Internal winning combination determining means (for example, internal lottery processing described later) for determining an internal winning combination based on detection of the start operation by the start operation detecting means;
A stop operation detecting means (for example, a stop switch 17S described later) for detecting the stop operation;
Stop control means (for example, a reel stop control process described later) for stopping and controlling the variation display of the symbol based on the determination result of the internal winning combination determining means and detection of the stop operation by the stop operation detecting means;
A game medium providing means (for example, a display combination search process and a medal payout process, which will be described later) for providing a game medium (for example, a medal described later) based on a combination of symbols stopped and displayed on the plurality of display rows;
When the first condition that a combination of symbols corresponding to a special internal winning combination (for example, “MB” described later) is displayed is satisfied, the gaming state is changed from the normal gaming state to the special gaming state (for example, described later). Special gaming state control means for ending the special gaming state when a predetermined internal winning combination (for example, “SB” to be described later) is won with a predetermined probability. (For example, bonus operation check processing and internal lottery processing described later),
When a second condition (for example, display of a combination of symbols corresponding to “cherry 2” described later) is satisfied, an internal winning combination relating to replay (for example, “replay” described later) is determined by the internal winning combination determining means. Re-game probability changing means (for example, a lottery value changing process during RT described later) for changing the determined probability;
In a replay high probability state (for example, an RT game state to be described later) with a high probability that an internal winning combination related to the replay will be determined, when the first condition can be satisfied, Special game transition condition notification means (for example, an effect content determination process and a liquid crystal display device described later) that performs notification that the game is capable of satisfying the condition during the game,
The stop control means performs stop control so that a combination of symbols corresponding to the replay is displayed with priority over other symbol combinations, and in the special gaming state, an internal winning related to the replay When the winning combination is determined by the internal winning combination determining means, the stop control means derives and changes the combination of symbols corresponding to the replay regardless of the timing of detecting the stop operation by the stop operation detecting means. A gaming machine characterized by stopping the display.

  In this gaming machine, when the first condition is satisfied, the state shifts to a special game (MB) state, and when the second condition is satisfied, the probability that the internal winning combination relating to the re-game is determined by the internal winning combination determining means is determined. Fluctuate. Therefore, the special game state includes a special game state that is a high probability state of replay with a high probability that an internal winning combination related to replay is determined, and a special game state that is not a high probability state of replay.

  When the internal winning combination relating to replay is determined by the internal winning combination determining means, the stop control means performs stop control so that the combination of symbols corresponding to the replay is displayed preferentially over other symbol combinations. Do. Therefore, in the special game state, when an internal winning combination related to replay is determined, a combination of symbols corresponding to the replay is displayed.

  As a result, in the special gaming state that is a replay high probability state, the possibility of displaying a combination of symbols other than the combination of symbols corresponding to the replay is lower, than in the special gaming state that is not a replay high probability state. The number of medals that can be earned decreases. That is, the number of game media that can be acquired in the special game changes.

  On the other hand, in this gaming machine, when it becomes possible to satisfy the first condition in the re-gaming high probability state, a notification that the game is a game that can satisfy the first condition is notified as a special game transition condition notification. During the game by means. When the player recognizes that the first condition can be satisfied by notification by the special game transition condition notification means, the player avoids satisfying the first condition and is in a special game state that is a re-probability high probability state. Can be avoided.

  Then, after the high reprobability state is completed, the player satisfies the first condition and shifts to the special game state. As a result, it is possible to enter a special game state that is not a replay high probability state, and to increase the number of medals to be paid out as compared to the special game state that is a replay high probability state.

  According to the present invention, the number of medals and the like that can be obtained in a special game (MB) can be changed, and the interest of the game can be enhanced.

In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding symbols”, and the maximum number is defined as four symbols. In the present embodiment, during the special game (MB), control for stopping the rotation of the corresponding reel is performed within a special specified time (90 msec) from when the stop button is pressed. In the present embodiment, the maximum number of symbols that move with the rotation of the reel within the special specified time is determined as one symbol.

  The reel stop control means displays the symbol combination as much as possible along the winning determination line using the specified time when an internal winning combination permitting display of the symbol combination related to winning is determined. Stop the reel rotation so that Further, the reel stop control means stops the rotation of the reel using the specified time so that a combination of symbols that are not permitted to be displayed by the internal winning combination is not displayed along the winning determination line.

  Thus, when the rotation of the plurality of reels is all stopped, the winning determination means determines whether or not the combination of symbols displayed along the winning determination line is related to winning. When it is determined that the prize is related to a prize, a bonus such as a medal payout is given to the player. A series of flows as described above is performed as one game in the pachislot.

  Also, in the pachislot, in the above-described series of flows, various effects can be achieved by using video display performed by a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, or a combination thereof. Done.

  When the start lever is operated, an effect random number value (hereinafter referred to as effect random number value) is extracted in addition to the random number value used for determining the internal winning combination. When the effect random number value is extracted, the effect content determining means determines, by lottery, what is to be executed this time from among a plurality of types of effect contents associated with the internal winning combination.

  When the content of the production is determined, the production execution means is linked to each opportunity such as when the rotation of the reel is started, when the rotation of each reel is stopped, or when the presence / absence of a prize is determined. To proceed with the production. In this way, in the pachislot, the player is given the opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. As a result, the player's interest is improved.

Next, with reference to FIG.4 and FIG.5, the structure of the circuit with which the pachislot 1 in this Embodiment is provided is demonstrated. The pachi-slot 1 includes a main control circuit 41, a sub-control circuit 42, and peripheral devices (actuators) that are electrically connected thereto.

[Main control circuit]
FIG. 4 is a block diagram showing a configuration of the main control circuit 41 of the pachi-slot 1 in the present embodiment.

  The main control circuit 41 includes a microcomputer 50 installed on a circuit board as a main component. The microcomputer 50 includes a main CPU 51, a main ROM 52, and a main RAM 53.

  The main ROM 52 has a control program (see FIGS. 28 to 49) executed by the main CPU 51, a data table such as an internal lottery table (see FIGS. 6 to 23), and various control commands (commands) to the sub control circuit. The data for transmitting is stored. The main RAM 53 is provided with a storage area (see FIGS. 24 to 27) for storing various data such as an internal winning combination determined by execution of the control program.

  Connected to the main CPU 51 are a clock pulse generation circuit 54, a frequency divider 55, a random number generator 56 and a sampling circuit 57. The clock pulse generation circuit 54 and the frequency divider 55 generate clock pulses. The main CPU 51 executes a control program based on the generated clock pulse. The random number generator 56 generates a random number within a predetermined range (for example, 0 to 65535). The sampling circuit 57 extracts one value from the generated random numbers.

  A switch or the like is connected to the input port of the microcomputer 50. The main CPU 51 receives input from a switch or the like and controls the operation of peripheral devices such as stepping motors 61L, 61C, 61R. The stop switch 17S detects that each stop button 17L, 17C, 17R has been pressed by the player (stop operation). The stop switch 17S constitutes a stop operation detection unit.

  The start switch 16S detects that the start lever has been operated by the player (start operation). The start switch 16S constitutes start operation detection means. The settlement switch 14S detects that the settlement button 14 has been pressed by the player.

  The medal sensor 35S detects that the medal received in the medal insertion slot 11 has passed through the selector 35 described above. The bet switch 12S detects that the bet button 12 has been pressed by the player. The medal sensor 35S and the bet switch 12S constitute insertion operation detection means.

  Peripheral devices whose operations are controlled by the microcomputer 50 include stepping motors 61L, 61C, 61R, a 7-segment display 6, and a hopper 33. A circuit for controlling the operation of each peripheral device is connected to the output port of the microcomputer 50.

  The motor drive circuit 62 controls the drive of stepping motors 61L, 61C, 61R provided corresponding to the reels 3L, 3C, 3R. The reel position detection circuit 63 detects a reel index indicating that the reel has made one rotation by an optical sensor having a light emitting part and a light receiving part according to each reel 3L, 3C, 3R.

  The stepping motors 61L, 61C, 61R have a configuration in which the momentum is proportional to the number of output pulses and the rotation axis can be stopped at a specified angle. The driving force of the stepping motors 61L, 61C, 61R is transmitted to the reels 3L, 3C, 3R via gears having a predetermined reduction ratio. Each time one pulse is output to each stepping motor 61L, 61C, 61R, each reel 3L, 3C, 3R rotates at a constant angle.

  The main CPU 51 counts the number of times the pulses are output to the stepping motors 61L, 61C, 61R after detecting the reel index, so that the rotation angles of the reels 3L, 3C, 3R Manage the number of rotations).

  Here, the management of the rotation angle of each reel 3L, 3C, 3R will be specifically described. The number of pulses output to the stepping motors 61L, 61C, 61R is counted by a pulse counter provided in the main RAM 53. Each time the output of a predetermined number of pulses (for example, 16 times) necessary for the rotation of one symbol is counted by the pulse counter, the symbol counter provided in the main RAM 53 is incremented by one. The symbol counter is provided for each reel 3L, 3C, 3R. The value of the symbol counter is cleared when the reel index is detected by the reel position detection circuit 63.

  In other words, in the present embodiment, by managing the symbol counter, it is possible to manage how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol on each reel 3L, 3C, 3R is detected with reference to the position where the reel index is detected.

  As described above, in the present embodiment, the maximum number of sliding symbols is set to four symbols. Therefore, when the left stop button 17L is pressed, the symbols of the left reel 3L in the middle of the left display window 4L and the symbols within the range up to four symbols ahead stop in the middle of the left display window 4L. It becomes a possible symbol.

  The display unit drive circuit 64 controls the operation of the 7-segment display 6. The hopper drive circuit 65 controls the operation of the hopper 33. The payout completion signal circuit 66 manages the detection of medals performed by the medal detection unit 33S provided in the hopper 33, and checks whether or not the medals discharged from the hopper 33 have reached the payout number.

[Sub control circuit]

<Configuration of data table stored in main ROM>
Next, the configuration of various data tables stored in the main ROM 52 will be described with reference to FIGS.

[Design arrangement table]
First, the symbol arrangement table will be described with reference to FIG. The symbol arrangement table defines the position of each symbol in the rotation direction of each reel 3L, 3C, 3R and data (hereinafter, symbol code) specifying the type of symbol arranged at each position.

  In the symbol arrangement table, the position of the symbol existing in the middle of the display windows 4L, 4C, 4R when the reel index is detected is defined as “0”. Then, “0” to “20” corresponding to the symbol counter are assigned to each symbol in the order in which the symbol position “0” advances in the reel rotation direction.

  That is, by referring to the value of the symbol counter (“0” to “20”) and the symbol arrangement table, the type of symbol displayed at the middle stage of the display windows 4L, 4C, 4R is specified. be able to. For example, when the value of the symbol counter corresponding to the left reel 3L is “1”, “cherry” at the symbol position “1” is displayed in the middle of the left display window 4L.

[Design combination table]
Next, the symbol combination table will be described with reference to FIG. The symbol combination table defines symbol combinations, display combinations, and payout numbers that are determined in advance according to the type of privilege. The display combination is data for identifying a combination of symbols displayed along the winning determination line.

  In the present embodiment, when the symbol combination displayed by the reels 3L, 3C, 3R along any of the winning determination lines 8a to 8d matches the symbol combination defined by the symbol combination table. It is determined that the prize is won. When it is determined that the prize is won, the player is given benefits such as paying out medals, replay operation, and bonus game operation. In addition, when the symbol combination displayed along each winning determination line 8a to 8d does not coincide with any of the symbol combinations defined by the symbol combination table, it is a so-called “losing”.

  The display combination is data for identifying a combination of symbols displayed along the winning determination line. This display combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. For example, when the symbol “bell” of each reel is displayed along the winning determination line 8a, “bell (00001000)” is determined as the display combination.

  The payout number represents the number of medals to be paid out to the player. When a numerical value of 1 or more is determined as the payout number, medals are paid out. In the present embodiment, medals are paid out when any of “Bell”, “Cherry 1”, and “Cherry 2” is determined as the display combination. “Bell”, “Cherry 1” and “Cherry 2” are collectively referred to as “small role”.

  When “replay” is determined as the display combination, re-playing is performed. On the other hand, when “MB” is determined as the display combination, the middle bonus game is activated. In the present embodiment, a game in the middle bonus game is a special game. When “SB” is determined as the display combination, the single bonus game is activated.

  In the present embodiment, when “Cherry 2” is determined as the display combination, the replay time (RT) is activated. In a game in which the RT is operated, the probability that an internal winning combination that allows display of a combination of symbols related to the operation of the re-game is won is changed until a predetermined condition is satisfied. In the present embodiment, in a game in which an RT operation is performed, the probability that an internal winning combination that permits display of a combination of symbols related to the re-game operation is increased.

[Bonus operating table]
Next, the bonus operation time table will be described with reference to FIG. The bonus operation time table defines data stored in a game state flag storage area (see FIG. 24) and a bonus end number counter provided in the main RAM 53 when a bonus operation is performed.

  The game state flag is data for identifying the type of bonus game to be operated. In the present embodiment, a middle bonus game, a challenge time, and a single bonus game are provided as bonus game types. The middle bonus game is referred to as an accessory continuous action device related to a so-called second type special accessory, and hereinafter referred to as “MB”.

  The challenge time is what is called a so-called second type special agent, and is hereinafter referred to as “CT”. The operation of CT is performed continuously while the operation of MB is performed. When the CT is activated, the small combination is determined as the internal winning combination regardless of the result of the internal lottery. The single bonus game is called a so-called ordinary character, and hereinafter referred to as “SB”.

  The bonus end number counter, the number-of-games counter, and the number-of-games counter are data for managing whether or not the specified number (payout number) or the specified number (game number) that triggers the end of the bonus game has been reached. is there. In the present embodiment, the MB operation ends when medals that reach the prescribed number “200” are paid out.

  That is, the numerical values defined by the bonus operation time table are stored in the counters, and the subtraction is performed through the bonus operation. 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 determination table]
Next, the internal lottery table determination table will be described with reference to FIG. The internal lottery table determination table defines the internal lottery table and the number of lotteries according to the gaming state.

  Specifically, when the gaming state is the general gaming state, the general gaming state internal lottery table is used, and “6” is set as the number of lotteries. On the other hand, when the gaming state is the SB gaming state, the internal lottery table for the SB gaming state is used, and “6” is set as the number of lotteries.

[Internal lottery table]
Next, the internal lottery table will be described with reference to FIGS. The internal lottery table defines a data pointer and a lottery value when the data pointer is determined 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 internal lottery process of the present embodiment, random numbers extracted from a predetermined numerical range “0 to 65535” are sequentially subtracted by lottery values defined according to each winning number. And then. An internal lottery is performed by determining whether the result of the subtraction is negative (whether a so-called “digit” has occurred). In other words, the winning number when the result of the subtraction becomes negative (“digit” occurs) is won, and the data point assigned to the winning number is acquired.

  Therefore, in the internal lottery process of the present embodiment, 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 is 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. 10 shows an internal lottery table for a general gaming state. The internal lottery table for the general gaming state defines lottery values and data pointers according to the winning numbers 1-6. For example, the bonus data pointer for which “SB” is determined as the internal winning combination is “2”. The probability that “2” is acquired as the bonus data pointer when referring to the internal lottery table for the general gaming state is “6553/65536”. That is, in the general gaming state, the probability that “SB” is determined as the internal winning combination is about 1/10.

  FIG. 11 shows an internal lottery table for the SB gaming state. The SB gaming state internal lottery table defines lottery values and data pointers according to the winning numbers 1 to 6. For example, when the SB gaming state internal lottery table is referenced, the probability that “1” is acquired as the small role / replay data pointer is “8980/65536”.

  FIG. 12 shows an RT gaming state replay internal lottery table. The RT game state replay internal lottery table defines lottery values and data pointers corresponding to the winning number 3. For example, when the RT game state replay internal lottery is referred to, the probability that “1” is acquired as the small role / replay data pointer is “50000/65536”.

[Internal winning combination determination table]
Next, 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. That is, 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 by the reels 3L, 3C, and 3R that are permitted to be displayed along the winning determination lines 8a to 8d. 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 “losing”, which indicates that display of any combination of symbols defined by the above-described symbol combination table is not permitted.

  FIG. 13 shows an internal winning combination determination table for a small combination / replay. The small winning combination / replay internal winning combination determining table defines small winning combinations and replay winning combinations for “0” to “4” of the small winning combination / replay data pointer. That is, 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. In the present embodiment, the “MB” internal winning combination indicates a specific example of a special internal winning combination, and the “Replay” internal winning combination indicates a specific example of an internal winning combination related to replay. Further, in the present embodiment, the “SB” internal winning combination is a specific example of a predetermined internal winning combination.

  FIG. 14 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 game for bonus data pointers “0” to “2”.

[Reel stop initial setting table]
Next, the reel stop initial setting table will be described with reference to FIG. The reel stop initial setting table defines data used to determine the number of sliding pieces for each of the reels 3L, 3C, and 3R in accordance with the small role / replay data pointer. Specifically, table selection data at the time of forward pressing, table change data at the time of forward pressing, and table selection data at the time of irregular pressing are defined.

  The forward push table selection data and the forward push table change data are data for designating a stop table (see FIGS. 16 and 18) to be referred to when forward push is performed. The forward pressing is a case where the first stop operation (first stop operation) is performed on the left reel 3L, and the pressing order of “left middle right” and “middle left and right” corresponds.

  The irregular pressing table selection data is data for designating a stop table (see FIG. 19) to be referred to when irregular pressing is performed. The irregular push is a case where the first stop operation is performed on the middle reel 3C or the right reel 3R, and the pushing order of “middle left / right”, “middle right / left”, “right middle left / right”, and “right left middle”. Is applicable.

  In the present embodiment, basically, after the stop operation is detected by the stop switch 17S, the rotation of the corresponding reel is stopped within 190 msec. Specifically, one of the number of sliding symbols “0” to “4” is added to the value of the symbol counter corresponding to the reel when the stop operation is detected, and the value obtained corresponds to the value obtained. The symbol position is determined as the symbol position at which the reel rotation stops (this is referred to as “scheduled stop position”). The symbol position corresponding to the value of the symbol counter corresponding to the reel when the stop operation is detected is the symbol position at which the rotation of the reel starts to be stopped, and this is referred to as a “stop start position”.

  In other words, the number of sliding pieces is the amount of rotation of the reel from when the stop operation is detected by the stop switch 17S until the rotation of the corresponding reel stops. In other words, the number of symbols passing through the middle of the corresponding display window in the period from when the stop operation is detected by the stop switch 17S until the rotation of the corresponding reel stops. This is grasped by the value of the symbol counter updated after the stop operation is detected by the stop switch 17S.

  Referring to the stop table, the number of sliding pieces is acquired according to the stop start position of each reel 3L, 3C, 3R. In the present embodiment, the number of sliding pieces is acquired based on the stop table, but this is temporary, and the acquired number of sliding pieces does not immediately determine the expected stop position of the reel.

  In the present embodiment, when there is a more appropriate number of sliding pieces than the number of sliding pieces acquired based on the stop table (hereinafter referred to as “the number of sliding pieces for stop data”), a priority table (FIG. 20) described later. The number of sliding pieces is changed with reference to (see). In this embodiment, the number of sliding pieces for stop data is used to determine the search order when comparing priorities for each symbol from the stop start position to the 4th symbol position that is the maximum number of sliding symbols. (See FIG. 21).

  In the present embodiment, the stop table to be referred to is properly used according to forward pressing and irregular pressing. In the case of the forward push, the first stop table (see FIG. 16) at the time of the forward push and the second and third stop stop tables (see FIG. 18) at the time of the forward push. On the other hand, in the case of irregular pressing, the irregular pressing stop table (see FIG. 19) is referred to.

[Stop table for first stop when pushing forward]
Next, with reference to FIG. 16, the first stop table for forward pressing will be described. The first stop table at the time of forward pressing defines the number of sliding pieces for stop data and the line change status according to the stop start positions “0” to “20” of the left reel 3L. The line change status is used when referring to a forward-pressing control change table which will be described later.

[Control change table when pressing forward]
Next, with reference to FIG. 17, the forward change control change table will be described. The forward push control change table defines C line check data and forward and second stop stop table numbers in accordance with the change target position (scheduled stop position of the left reel 3L). For example, if the line change status acquired based on the first stop table at the time of forward pressing is “0” and the planned stop position of the left reel 3L is “15”, the C line check data is “0”. Thus, the stop table number for the second and third stops becomes “1” when pushed forward.

[Stop table for 2nd and 3rd stop when pushing forward and stop table when pushing irregularly]
Next, referring to FIGS. 18 and 19, the second and third stop tables for forward pressing and the stop table for irregular pressing will be described. The 2nd and 3rd stop table for stoppages and the stop table for irregular presses define 1-byte stop data according to each of symbol positions “0” to “20”.

  The stop data defined by the stop table for the second and third stops at the time of forward pressing and the stop table at the time of anomalous pressing indicate whether the symbol position associated with the stop data is appropriate as the position at which the reel rotation stops. Have information. The stop data includes information indicating whether or not the corresponding symbol position is appropriate as a position to stop the rotation of the reel in the bit corresponding to the column “A line” and the bit corresponding to the column “B line”. It is to be assigned. In addition, the stop data defines which of the two types of information should be adopted by assigning bits corresponding to the “line change” column.

  That is, the second and third stop tables for forward pressing and the stop table for irregular pressing define a plurality of methods for determining the position at which the reels stop rotating. Therefore, even if the stop start position is the same symbol position, the position where the reel rotation is stopped can be varied based on the stop position at the time of the first stop. Such a configuration is intended to compress information.

  The number of stop data sliding pieces is determined as follows. First, it is specified which of the eight bit strings constituting the stop data is to be referred to according to the type of the stop button in which the stop operation is detected. For example, when the middle stop button 17C is pressed, a column of “middle reel A line” of bit 4 is designated.

  Then, referring to the designated bit string, a search is sequentially performed as to whether or not “1” is defined as the corresponding data for each symbol position from the stop start position to the range of the maximum number of sliding symbols. As a result of this search, the difference from the stop start position to the symbol position where “1” is defined as the corresponding data is determined as the number of stop pieces for stop data.

  Whether or not the bit string to be referred to is changed from the “A line” column to the “B line” column refers to the “line change” column and “1” is defined in the data corresponding to the stop start position. It is determined by whether or not. When it is determined to change the line, the column “B line” is designated and the above search is performed.

  FIG. 18 shows the second- and third-stop stop tables at the time of forward press, which are referred to when the stop-table number for the second and third stops at the time of forward press is “1”. When the 2nd and 3rd stop table is referred to when the forward push is performed, stop data is defined such that a combination of symbols corresponding to the replay is displayed along the cross-down line 8c (see FIG. 2). Yes.

  In the present embodiment, the combination of symbols corresponding to the replay is cross-up in the second and third stop table when the second and third stop tables are “2”. Define stop data as displayed along line 8d (see FIG. 2).

  FIG. 19 shows an irregular pressing stop table referred to when the irregular pressing table selection data is “1”. When this irregular pressing stop table is referred to, stop data is defined such that a combination of symbols corresponding to replay is displayed along any of the winning determination lines 8a to 8d.

[Priority table]
Next, the priority table will be described with reference to FIG. The priority order table defines the pull-in data according to a predetermined priority order.

  The priority table is used to search whether there is a more appropriate number of sliding symbols in addition to the number of sliding data sliding symbols. The priority order defines the order of preferential drawing between the types of symbol combinations related to winning. The pull-in data is represented as 1-byte data. In the structure of the pull-in data, a unique symbol combination is assigned to each bit in the same manner as the internal winning combination and display combination described above.

  In this embodiment, first, the number of sliding pieces for stop data is acquired based on the stop table described above, but if there is a more appropriate number of sliding pieces in addition to the number of sliding pieces for stop data, The number of sliding pieces is changed appropriately. In other words, regardless of the number of sliding symbols acquired by the stop table, a more appropriate number of sliding symbols is determined based on the priority order of the combination of symbols permitted to be displayed by the internal winning combination.

  The priority order table of the present embodiment defines priority orders “1” to “3” and pull-in data according to the internal winning combination. In this priority order table, pull-in data corresponding to “replay” is defined for priority “1”, and pull-in data corresponding to “small role” is defined for priority “2”. In addition, for the priority “3”, pull-in data corresponding to “bonus” is defined. Therefore, in the present embodiment, the display of the “replay” symbol combination is given priority over the display of the other symbol combinations.

[Priority order table]
Next, the priority order table will be described with reference to FIG. The priority order table defines an order of priority (hereinafter referred to as “priority order”) from a numerical value range “0” to “4” predetermined as the number of sliding frames.

  In the priority order table, each numerical value is searched in the order from the lower priority to the higher priority, and as a result, the numerical value corresponding to the priority order “1” is preferentially applied. The priority order table is provided on the assumption that there are a plurality of sliding frames having the same priority order, and a higher priority order is applied.

  The priority order table defines the priority order based on the number of stop data sliding pieces described above. In other words, the priority order of numerical values to be preferentially applied is determined based on the number of sliding pieces for stop data.

<Configuration of storage area provided in main RAM>
Next, the configuration of various storage areas provided in the main RAM 53 will be described with reference to FIGS.

[Internal winning combination storage area]
First, the configuration of the internal winning combination storing area will be described with reference to FIG. The internal winning combination storage area stores the above-described internal winning combination represented by 1-byte data.

  In the internal winning combination storage area, when “1” stands for a target bit, display of a combination of symbols corresponding to the bit is permitted. When all bits are “0”, the content is lost. When “1” stands for a plurality of bits in the internal winning combination storing area, display of a combination of symbols corresponding to each bit is permitted.

  The main RAM 53 is provided with a display combination storage area (not shown) in which the display combination described above is stored. The configuration of the display combination storing area is the same as that of the internal winning combination storing area. In the display combination storage area, when “1” stands for a target bit, it indicates that a combination of symbols corresponding to the bit is displayed on the winning determination line (see FIG. 2). Further, when all the bits are “0”, it indicates that the symbol combination related to winning is not displayed on the winning determination line.

  In the present embodiment, the internal winning combination storage area 1 is provided as the storage area type. All internal winning combinations defined in the present embodiment are stored in the internal winning combination storage area 1. If not all internal winning combinations can be stored in the internal winning combination storing area 1 alone, for example, an internal winning combination storing area 2 is provided.

[Coverage storage area]
Next, the configuration of the carryover combination storage area will be described with reference to FIG. When “MB” is determined as the internal winning combination as a result of the internal lottery, the internal winning combination is stored as a carryover combination in the carryover combination storage area.

  The carryover combination (MB) stored in the carryover combination storage area is not cleared until the corresponding symbol combination (set to “mirror-diamond-diamond” in this embodiment) is displayed on the winning determination line. Retained. While the carryover combination is stored in the carryover combination storage area, the carryover combination is stored in the internal winning combination storage area in addition to the internal winning combination determined by the internal lottery.

[Game state flag storage area]
Next, the configuration of the game state flag storage area will be described with reference to FIG. The gaming state flag storage area stores a gaming state flag consisting of 1 byte. In the game state flag, a unique bonus game or RT is assigned to each bit.

  When “1” is set to the target bit in the game state flag storage area, the corresponding bonus game or RT is activated. In the present embodiment, when all bits are “0”, it is defined as a general gaming state.

[Design storage area]
Next, the configuration of the symbol storage area will be described with reference to FIG. The symbol storage area stores data (symbol code) specifying symbols of the reels 3L, 3C, 3R displayed along any of the winning determination lines 8a to 8d.

  For example, in the case of the small V-shaped line 8a, the symbol code related to the symbol displayed in the upper part of the left display window 4L, the symbol code related to the symbol displayed in the middle part of the middle display window 4C, and the upper part of the right display window 4R. The symbol code related to the symbol to be displayed is stored. The symbol storage area shown in FIG. 25 is a configuration example when the symbol counter of each reel 3L, 3C, 3R is “1” (see FIG. 6). The display combination is determined by determining whether or not the symbol combination stored in the symbol storage area matches the symbol combination defined by the symbol combination table described above.

[Predicted storage area for display combination]
Next, the configuration of the expected display combination storing area will be described with reference to FIG. The expected display combination storing area is configured to include a left display display expected storage area, a middle reel display combination expected storage area, and a right reel display combination expected storage area according to the type of reel.

  In each expected display combination storing area, priority attraction ranking data determined in accordance with each symbol position “0” to “20” of the corresponding reel is stored. In the present embodiment, by referring to the expected display combination storing area, it is searched whether there is a more appropriate number of sliding symbols in addition to the number of sliding symbols determined based on the stop table described above. .

  The contents of the priority order pull-in data stored in the expected display combination storing area differ depending on the type of the priority table referred to when determining the priority pull-in order data. In this expected display combination storing area, bit 3 of the priority pull-in order data corresponds to “replay” and bit 2 corresponds to “small combination”. Bit 1 corresponds to “bonus” and bit 0 corresponds to “stoppable”.

  “Can stop” corresponding to bit 0 is for losing. Then, when the symbol at the target symbol position is displayed, if a symbol combination corresponding to a winning combination that has not been determined as an internal winning combination is displayed, “0” is set to bit 0 of the priority pull-in ranking data. Stored.

  The priority pull-in order data indicates that the higher the value, the higher the priority order. For example, in the expected display combination storing area shown in FIG. 26, the priority order pull-in data with the highest priority is “00001111” (replay + small combination + bonus). On the other hand, the priority order pull-in data with the lowest priority is “00000000” (stop prohibition).

  By referring to the priority pull-in order data, it is possible to relatively evaluate the priority order among the symbols arranged on the peripheral surface of the reel. That is, the symbol for which the largest value is determined as the priority pull-in ranking data is the symbol with the highest priority. Therefore, it can be said that the priority pull-in rank data indicates the rank between the symbols arranged on the peripheral surface of the reel. When there are a plurality of symbols having the same value of the priority pull-in order data, one symbol is determined according to the priority order defined by the above-described priority order table (see FIG. 21).

<Description of main control circuit operation>
Next, the contents of the program executed by the main CPU 51 of the main control circuit 41 will be described with reference to FIGS.

[Main flowchart by control of main CPU]
First, with reference to FIG. 27, the main flowchart by control of the main CPU51 is demonstrated.

  When power is turned on to the pachi-slot 1, first, the main CPU 51 performs an initialization process (S1). In this initialization process, whether or not the main RAM 53 is normal, input / output port initialization, and the like are performed.

  Next, the main CPU 51 clears the designated storage area in the main RAM 53 (S2). The designated storage area is a storage area that needs to be deleted for each game, such as an internal winning combination storage area or a display combination storage area.

  Next, the main CPU 51 performs a bonus operation monitoring process which will be described later with reference to FIG. 28 (S3). In this process, a process for continuing the operation of the CT during the MB gaming state is performed. Next, the main CPU 51 performs a medal acceptance / start check process which will be described later with reference to FIG. 29 (S4). In this processing, input checks of the medal sensor 35S and the start switch 16S are performed.

  Next, the main CPU 51 extracts a random number value and stores it in a random value storage area provided in the main RAM 53 (S5). When the extracted random number value is stored in the random value storage area, the main CPU 51 performs an internal lottery process described later with reference to FIGS. 30 and 31 (S6). In this process, the internal winning combination is determined by lottery based on a random value.

  Next, the main CPU 51 performs a reel stop initial setting process which will be described later with reference to FIG. 29 (S7). In this process, the reel stop initial setting table (see FIG. 15) is referred to, and various data used to stop the rotation of the reels 3L, 3C, 3R are determined. In addition, the priority order reflecting the internal winning combination is determined for each symbol arranged on the peripheral surface of each reel.

  Next, the main CPU 51 transmits a start command to the sub-control circuit 42 (S8). The start command includes a parameter for specifying an internal winning combination. Next, the main CPU 51 requests the start of rotation of all reels (S9). When the start of rotation of all reels is requested, the driving of the stepping motors 61L, 61C, 61R is controlled by an interrupt process (see FIG. 49) executed at a constant cycle (1.1173 msec), and the reels 3L, 3C are controlled. , 3R starts to rotate. At this time, each of the reels 3L, 3C, 3R is controlled so as to be accelerated until its rotation reaches a constant speed, and thereafter, the constant speed is maintained.

  Next, the main CPU 51 determines whether or not the rotation of each reel 3L, 3C, 3R is a constant speed (S10). When it is determined that the rotation of each reel 3L, 3C, 3R is not a constant speed, the main CPU 51 waits until the rotation of each reel 3L, 3C, 3R reaches a constant speed.

  On the other hand, when it is determined that the rotation of each reel 3L, 3C, 3R is a constant speed, the main CPU 51 performs a reel stop control process which will be described later with reference to FIG. 37 (S11). In this process, the rotation of the corresponding reel is stopped based on the timing when the stop buttons 17L, 17C, and 17R are pressed and the internal winning combination.

  Next, the main CPU 51 performs a display combination search process which will be described later with reference to FIG. 35 (S12). In this process, the symbol combination table (see FIG. 7) is referred to, and the display combination and the number of medals to be paid out are determined based on the symbol combination displayed along the winning determination lines 8a to 8d. Next, the main CPU 51 performs a display combination determination process which will be described later with reference to FIG. 45 (S13). In this process, RT transition is managed based on the display combination.

  Next, the main CPU 51 transmits a display combination command to the sub-control circuit (S14). The display combination command includes parameters that specify the display combination, the number of payouts, and the like. Next, the main CPU 51 performs medal payout processing (S15). In this process, the hopper 33 is driven and the number of credits is updated based on the payout number determined in S12.

  Next, the main CPU 51 refers to the gaming state flag storage area to determine whether or not the bonus operating flag is on (S16). In the gaming state flag storage area according to the present embodiment, an SB gaming state flag, a CT gaming state flag, and an MB gaming state flag are stored as bonus operating flags.

  When it is determined that the bonus operating flag is ON, the main CPU 51 performs a bonus end check process described later with reference to FIG. 46 (S17). 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.

  On the other hand, when it is determined that the bonus operating flag is on, or when the bonus end check process of S17 is ended, the main CPU 51 performs RT game number counter update processing described later with reference to FIG. Perform (S18). In this process, the remaining number of games in the RT gaming state is updated. In the present embodiment, when the RT game number counter reaches “0”, the RT operation ends. In the present embodiment, the game in which the RT is operated is set to 100 times.

  When the RT game number counter update process ends, the main CPU 51 performs a bonus operation check process which will be described later with reference to FIG. 48 (S19). In this process, it is checked whether or not the operation of the MB is started and whether or not replaying is performed. When the bonus operation check process ends, the main CPU 51 returns the process to step S2 again.

[Bonus activation monitoring process]
Next, the bonus operation monitoring process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not the MB gaming state flag (see FIG. 24) is on (S31). When determining that the MB gaming state flag is not on, the main CPU 51 ends the bonus operation monitoring process and shifts the process to the main flow (see FIG. 27).

  On the other hand, when it is determined that the MB gaming state flag is ON, the CT operation time process is performed based on the bonus operation time table (see FIG. 8) (S32). In this process, the CT gaming state flag is turned on. Thereafter, the main CPU 51 ends the bonus operation monitoring process and shifts the process to the main flow.

[Medal reception / start check processing]
Next, with reference to FIG. 29, the medal acceptance / start check process will be described.

  First, the main CPU 51 determines whether or not the automatic insertion counter is 0 (S41). When it is determined that the automatic insertion counter is 0, the main CPU 51 permits medal passage (S42). In this process, the selector solenoid is driven, and the passage of medals in the selector is prompted. When the medal passage permission is given, the main CPU 51 proceeds to the process of S45.

  When determining that the automatic insertion counter is not 0, the main CPU 51 copies the automatic insertion counter to the insertion number counter (S43). Thereafter, the main CPU 51 clears the automatic insertion counter (S44). The automatic insertion counter is data for identifying whether or not “replay” has been established in the previous unit game. When “Replay” is established, the medals for the number of coins inserted in the previous unit game are automatically inserted into the automatic insertion counter. That is, the processes of S43 and S44 are processes for performing a replay.

  Next, the main CPU 51 sets 3 as the maximum value of the insertion number counter (S45). Next, the main CPU 51 determines whether or not passage of medals has been detected (S46). When determining that the passage of medals has not been detected, the main CPU 51 proceeds to the process of S52.

  On the other hand, when determining that the passage of medals has been detected, the main CPU 51 determines whether or not the inserted number counter has reached the maximum value (S47). When determining that the inserted number counter has not reached the maximum value, the main CPU 51 adds 1 to the inserted number counter (S48).

  Next, the main CPU 51 stores 4 in the effective line counter (S49). Next, the main CPU 51 transmits a medal insertion command to the sub control circuit 42 (S50). The medal insertion command includes a parameter for specifying the number of inserted coins. When the medal insertion command is transmitted, the main CPU 51 proceeds to the process of S52.

  When determining that the inserted number counter is the maximum value in the processing of S47, the main CPU 51 adds 1 to the credit counter (S51). After S51, after S50, or when it is determined that the passage of medals has not been detected in the processing of S46, the main CPU 51 checks the bet switch (S52). In this process, a numerical value corresponding to the bet button is added to the inserted number counter and subtracted from the credit counter.

  Next, the main CPU 51 determines whether or not the insertion number counter has reached the maximum value (S53). When determining that the inserted number counter has not reached the maximum value, the main CPU 51 returns the process to S46. On the other hand, when determining that the insertion number counter has reached the maximum value, the main CPU 51 determines whether or not the start switch is ON (S54).

  When determining that the start switch is not on, the main CPU 51 returns the process to S46. On the other hand, when determining that the start switch is on, the main CPU 51 prohibits medal passage (S55). The selector solenoid is not driven, and the inserted medal is expelled. When this process ends, the main CPU 51 ends the medal acceptance / start check process, and moves the process to the main flow (see FIG. 27).

[Internal lottery processing]
Next, an internal lottery process will be described with reference to FIGS.

  First, the main CPU 51 acquires a game state flag, and determines the type and number of lotteries of the internal lottery table corresponding to the game state based on the internal lottery table determination table (see FIG. 9) (S61). In this process, the game state storage area 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 of lottery value subtraction and determination of whether or not a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 51 performs a lottery value changing process during RT which will be described later with reference to FIG. 32 (S62). In this process, the lottery value of the winning number related to replay is changed according to the gaming state.

  Next, the main CPU 51 obtains a random value stored in the random value storage area and sets it as a determination random value (S63). Next, the main CPU 51 sets 1 as the initial value of the winning number (S64).

  Next, the main CPU 51 refers to the internal lottery table and acquires a lottery value corresponding to the winning number (S65). Subsequently, the main CPU 51 subtracts the lottery value from the determination random number value (S66). Next, the main CPU 51 determines whether or not a digit has been made (S67). When it is determined that no digit has been placed, the main CPU 51 adds 1 to the winning number and subtracts 1 from the number of lotteries (S68).

  Next, the main CPU 51 determines whether or not the number of lotteries is 0 (S69). When determining that the number of lotteries is not 0, the main CPU 51 returns the process to S65. On the other hand, when it is determined that the number of lotteries is 0, the main CPU 51 sets 0 as the small role / replay data pointer and 0 as the bonus data pointer (S70).

  When it is determined that a digit has been obtained in the process of S67, the main CPU 51 acquires a small role / replay data pointer and a bonus data pointer according to the current winning number (S71). After the processing of S71 or S70, the main CPU 51 refers to the small winning combination / replay internal winning combination determination table, and acquires the internal winning combination based on the small winning combination / replay data pointer (S72). Then, the main CPU 51 stores the acquired internal winning combination in the internal winning combination storing area (see FIG. 22) (S73).

  Next, the main CPU 51 determines whether or not the CT gaming state flag is on (S74). When determining that the CT gaming state flag is ON, the main CPU 51 sets “1” in bits 4 to 6 of the internal winning combination storing area (S75). Thereby, in the CT gaming state (MB gaming state), all the small combinations are determined as internal winning combinations. Therefore, display of all symbol combinations related to the payout of medals is permitted.

  After the process of S75, or when it is determined in the process of S74 that the CT gaming state flag is not on, the main CPU 51 determines whether or not the data stored in the carryover combination storage area is “00000000” ( S76). When determining that the data stored in the carryover combination storage area is “00000000”, the main CPU 51 refers to the bonus internal winning combination determination table and acquires the internal winning combination based on the bonus data pointer ( S77).

  Next, the main CPU 51 determines whether or not the internal winning combination is “SB” (S78). When determining that the internal winning combination is “SB”, the main CPU 51 stores the result in the internal winning combination storing area (S79). Next, the main CPU 51 determines whether or not the MB gaming state flag is on (S80).

  When it is determined in the process of S80 that the MB gaming state flag is on, the main CPU 51 performs a bonus end process (S81). At this time, in the gaming state flag storage area (see FIG. 24), the MB gaming state flag and the CT gaming state flag are respectively turned on, but the main CPU 51 turns off only the MB gaming state flag. The CT gaming state flag is turned off in the bonus end check process (see FIG. 46) after being referred to in order to change the maximum number of sliding pieces in the reel stop control process (see FIG. 37).

  Next, the main CPU 51 transmits a bonus end command to the sub-control circuit 42 (S82). Thereby, the sub-control circuit 42 is notified that the operation of the MB is completed.

  In the process of S78, when determining that the internal winning combination is not “SB”, the main CPU 51 determines whether or not the MB gaming state flag is ON (S83). When determining that the MB gaming state flag is not on, the main CPU 51 stores the acquired internal winning combination in the carryover combination storing area (S84).

  After the processing of S82 and S84, when it is determined in S80 and S83 that the MB gaming state flag is ON, it is determined in S76 that the data stored in the carryover combination storage area is not “00000000”. At this time, the main CPU 51 calculates the logical sum of the carryover combination storage area and the internal winning combination storage area, and stores the result in the internal winning combination storage area (S85). Thereafter, the main CPU 51 ends the internal lottery process and shifts the process to the main flow (see FIG. 27).

[Drawing value change processing during RT]
Next, with reference to FIG. 32, the lottery value changing process during RT will be described. This process constitutes a replay probability changing means for changing the probability that “replay” is determined as an internal winning combination.

  First, the main CPU 51 refers to the gaming state flag storage area (see FIG. 24) and determines whether or not the RT gaming state flag is on (S91). When determining that the RT gaming state flag is not on, the main CPU 51 ends the lottery value changing process during RT and shifts the process to the internal lottery process (see FIG. 30).

  On the other hand, when determining that the RT gaming state flag is on, the main CPU 51 refers to the RT gaming state replay internal lottery table (see FIG. 12) and changes the lottery value of the winning number related to the replay (S92). . That is, the lottery value of the winning number “3” defined by the general gaming state internal lottery table (see FIG. 10) is the lottery value of the winning number “3” defined by the RT gaming state replay internal lottery table. Changed to When the process of S92 is completed, the main CPU 51 ends the lottery value changing process during RT, and shifts the process to the internal lottery process.

[Reel stop initial setting process]
Next, the reel stop initial setting process will be described with reference to FIG.

  First, the main CPU 51 refers to the reel stop initial setting table (see FIG. 15), and based on the small role / replay data pointer, forward push table selection data, forward push table change data, and irregular push push table selection. Data is selected and stored in the main RAM 53 (S121).

  Next, the main CPU 51 refers to the gaming state flag storage area (see FIG. 24) and determines whether or not the CT gaming state flag is on (S122). When it is determined that the CT gaming state flag is ON, the main CPU 51 changes each data stored in the main RAM 53 in the process of S121 to CT stop table selection data (S123). CT stop table selection data is data for selecting a CT stop table (not shown). In the CT stop table according to the present embodiment, the number of sliding pieces of the left reel 3L is defined as “0”.

  After the process of S123 or when it is determined in the process of S122 that the CT gaming state flag is not on, the main CPU 51 stores the rotating identifier “0FFH (11111111B)” in each symbol storage area (see FIG. 25). (S124). Next, the main CPU 51 stores 3 in the stop button non-operating counter provided in the main RAM 53 (S125). The stop button non-operating counter is a counter for managing the number of stop buttons whose stop operation is not detected.

  Next, the main CPU 51 performs a display combination prediction storing process which will be described later with reference to FIG. 34 (S126). When the process of S126 is completed, the main CPU 51 ends the reel stop initial setting process, and moves the process to the main flow (see FIG. 27).

[Indicator expected storage process]
Next, the expected display combination storing process will be described with reference to FIG.

  First, the main CPU 51 stores the stop button non-operating counter in the main RAM 53 as the number of searches (S141). Next, the main CPU 51 determines a search target reel (S142). The main CPU 51 determines reels to be searched in order from the leftmost reel among the rotating reels.

  For example, when all (three) reels are being rotated, the left reel 3L is first determined as the search target reel. Then, when each process up to S156 described later is performed on the left reel 3L and the process returns to S142, the middle reel 3C is subsequently determined as a search target reel. Finally, the right reel 3R is determined as a search target reel.

  Next, the main CPU 51 designates the address of the expected display combination storing area based on the determined reel to be searched (S143). For example, when the search target reel is the left reel 3L, the top address (the address of the symbol position “0”) of the left reel display combination expected storage area is designated.

  Next, the main CPU 51 sets “0” as the symbol position data and sets “21” as the symbol check count (S144). Subsequently, the main CPU 51 refers to the symbol arrangement table (see FIG. 6), acquires a symbol code based on the symbol position data, and stores the symbol code in the symbol storage area (S145).

  For example, when the search target reel is the left reel 3L and the current symbol position data is “0”, the symbol code “00000110 (Cherry)” defined in the symbol position “1” of the left reel 3L is the symbol storage area. Is stored in the upper stage of the left display window 4L. Further, the symbol code “00000011 (replay)” defined at the symbol position “20” of the left reel 3L is stored in the lower stage of the left display window 4L in the symbol storage area.

  Next, the main CPU 51 performs a display combination search process which will be described later with reference to FIG. 35 (S146). In this process, a combination of symbols that may be displayed on the four winning determination lines 8a to 8d is searched based on a symbol code acquired according to each symbol position of the search target reel. That is, the combination of symbols that may be displayed on the four winning determination lines 8a to 8d is searched assuming that the rotation of the reel is stopped at each symbol position.

  Next, the main CPU 51 performs a priority pull-in rank data acquisition process which will be described later with reference to FIG. 36 (S147). In this process, priority pull-in rank data is determined based on the combination of symbols specified as a result of the search by the display combination search process and the priority table.

  Next, the main CPU 51 stores the determined priority pull-in order data in the expected display combination storing area (S148). For example, when the current symbol position data is “0”, the priority pull-in order data is stored at the symbol position “0” in the left reel display combination expected storage area. Next, the main CPU 51 adds 1 to the address of the expected display combination storage area and the symbol position data, and subtracts 1 from the number of symbol checks (S149).

  Next, the main CPU 51 determines whether or not the number of symbol checks is 0 (S150). When determining that the symbol check count is not 0, the main CPU 51 shifts the processing to S145. On the other hand, when determining that the symbol check count is 0, the main CPU 51 subtracts 1 from the search count (S151).

  Next, the main CPU 51 determines whether or not the number of searches is 0 (S152). When determining that the number of searches is 0, the main CPU 51 ends the expected display combination storing process and moves the process to the reel stop initial setting process (see FIG. 33). On the other hand, when determining that the number of searches is not 0, the main CPU 51 stores the rotating identifier in the entire symbol storage area (S153).

  Next, the main CPU 51 determines whether or not the stop button non-operation counter is 3 (S154). When it is determined that the stop button non-operating counter is 3, that is, when the reels 3L, 3C, 3R are rotating, the main CPU 51 shifts the processing to S142. On the other hand, when determining that the stop button non-operating counter is not 3, the main CPU 51 determines a search target reel based on the operation stop button, and sets a scheduled stop position as symbol position data (S155).

  Next, the main CPU 51 refers to the symbol arrangement table and stores the symbol code in each symbol storage area based on the symbol position data (S156). That is, the symbol codes of symbols displayed on the winning determination lines 8a to 8d are stored for the reels whose rotation has already been stopped. Then, a display combination search process described later is performed based on a combination of the above-described symbols of the reels whose rotation has already been stopped and symbols arranged at the respective symbol positions of the rotating reel. When the process of S156 is completed, the main CPU 51 shifts the process to S142.

[Indicator search process]
Next, the display combination search process will be described with reference to FIG.

  First, the main CPU 51 clears the display combination storing area and sets the top address of the symbol storing area (see FIG. 25) (S181). That is, an address corresponding to the small V-shaped line 8a is designated. Next, the main CPU 51 sets the head address of the symbol combination table (see FIG. 7) (S182). That is, an address corresponding to the MB symbol combination “mirror-diamond-diamond” is set.

  Next, the main CPU 51 compares the symbol combination defined by the symbol combination table with the three symbol codes stored in the symbol storage area (S183). That is, according to each winning determination line 8a to 8d, a combination of symbols composed of symbols of the left reel 3L, symbols of the middle reel 3C and symbols of the right reel 3R, and combinations of symbols defined by the symbol combination table. To be compared.

  Next, the main CPU 51 determines whether or not one of the three symbol codes excluding the identifier indicating that it is rotating matches the symbol combination defined by the symbol combination table (S184). For example, when the three symbol codes stored in the small V-shaped line 8a of the symbol storage area indicate “replay-rotating-rotating”, it is determined that the symbol combination “mirror-diamond-diamond” matches. Is done.

  When it is determined that they match in the process of S185, the main CPU 51 acquires a winning action flag and storage area addition data (S185). The winning operation flag is data representing a display combination, and is composed of eight bit strings as in the case of the symbol combination table data. The storage area addition data is data used to specify one of the display combination storage areas when there are a plurality of display combination storage areas.

  Next, the main CPU 51 sets the address of the display combination storage area 1 and adds the address based on the storage area addition data (S186). For example, when the storage area addition data is “0”, the address of the display combination storage area 1 is set. Next, the main CPU 51 stores the logical sum of the acquired winning action flag and the designated display combination storage area in the display combination storage area (S187).

  Next, the main CPU 51 determines whether or not the number of searches is 0 (S188). If the number of searches is 0 when this processing is performed, the rotation of all reels has stopped. That is, the display combination search process is performed in S12 of the main flowchart shown in FIG. When it is determined that the number of searches is 0, the main CPU 51 acquires the payout number, and adds the acquired payout number to the payout number counter (S189).

  After the process of S189, when it is determined that they do not match in the process of S184, or when it is determined that the number of searches is not 0 in the process of S188, the main CPU 51 updates the address of the symbol combination table (S190). For example, if the current address is an address designating an MB symbol combination, the address is updated to an address designating an SB symbol combination.

  Next, the main CPU 51 determines whether or not the data corresponding to the updated address is an end code (S191). If the main CPU 51 determines that it is not an end code, that is, it has not searched for all symbol combinations defined by the symbol combination table, the main CPU 51 shifts the processing to S183.

  On the other hand, when determining that it is an end code, the main CPU 51 determines whether or not the number of times corresponding to the valid line counter has been executed (S192). In this processing, the value of the effective line counter stored in the main RAM 53 is transferred in advance to a register, and it is determined whether or not the value obtained by subtracting 1 from the value transferred to this register has become 0. Therefore, in the process of S192, the effective line counter itself stored in the main RAM 53 is not subtracted.

  When determining that the number of times corresponding to the valid line counter has been executed in the process of S192, the main CPU 51 ends the display combination search process. On the other hand, when determining that the number of times corresponding to the valid line counter has not been executed, the main CPU 51 updates the address of the symbol storage area (S193). For example, if the current address is an address designating the small V-shaped line 8a, it is updated to an address designating the small mountain line 8b. When the process of S193 is completed, the main CPU 51 shifts the process to S182.

[Priority acquisition order data acquisition processing]
Next, with reference to FIG. 36, the priority pull-in rank data acquisition process will be described.

  First, the main CPU 51 clears the bit of the display combination storage area corresponding to the display combination whose symbol of the search target reel is “ANY” (S211). “ANY” indicates an arbitrary symbol, and the display combination is established regardless of which symbol is displayed. For this reason, in the present embodiment, when the priority pull-in order data is acquired, the bit of the display combination storage area corresponding to the display combination whose symbol of the search target reel is “ANY” is not referred to.

  Next, the main CPU 51 sets the head address of the priority table (see FIG. 20) and sets the number of checks (S212). In the present embodiment, “3” is set as the number of checks.

  Next, the main CPU 51 sets “1” as the initial value of the priority order, and sets “0” as the initial value of the priority pull-in order data (S213). Next, the main CPU 51 refers to the priority order table corresponding to the gaming state, and obtains pull-in data based on the current priority order (S214). Then, the main CPU 51 performs a logical product of the internal winning combination storing area, the display combination storing area, and the drawn-in data (S215).

  Next, the main CPU 51 determines whether or not the result of the logical product is 0 (S216). When determining that the logical product is not 0, the main CPU 51 turns on the carry flag (S217). That is, when the internal winning combination corresponding to the contents of the pull-in data is won and the combination of symbols corresponding to the internal winning combination is displayed, the carry flag is turned on.

  After the process of S217 or when it is determined in the process of S216 that the result of the logical product is 0, the main CPU 51 rotates the bit pattern of the priority pull-in rank data including the carry flag to the left (S218). Since the bit pattern is shifted to the left, the priority pull-in rank data becomes larger as the priority rank is higher.

  Next, the main CPU 51 subtracts 1 from the number of checks and adds 1 to the priority (S219). Then, the main CPU 51 determines whether or not the number of checks is 0 (S220). When determining that the number of checks is not 0, the main CPU 51 shifts the processing to S214. On the other hand, when determining that the number of checks is 0, the main CPU 51 rotates the bit pattern of the priority pull-in order data to the left (S221).

  Next, the main CPU 51 adds 1 to the priority pull-in rank data (S222). Subsequently, the main CPU 51 performs a stop prohibition check process (S223). Then, the main CPU 51 ends the priority pull-in order data acquisition process, and shifts the process to the expected display combination storing process (see FIG. 34).

  In the process of S223, when all the reels (reels corresponding to symbols other than “ANY”) that are required to confirm the winning of the internal winning combination having “ANY” at the third stop are stopped, the internal winning combination It is determined whether or not a winning combination is displayed. When a winning combination that is not won as an internal winning combination is displayed, “00000000” is set as priority drawing data so that a symbol necessary for confirming a winning is not displayed.

  For example, when “Cherry 1” is not won as an internal winning combination, it is assumed that a cherry symbol is displayed on the upper stage of the left display window 4L by the first stop operation. In this case, it is determined whether or not a bell symbol is displayed in the middle stage of the middle display window 4C by the subsequent stop operation. If displayed, “00000000” is set as priority drawing data, and the middle display is displayed. The bell symbol is not displayed in the middle of the window 4C.

[Reel stop control process]
Next, the reel stop control process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not a valid stop button has been pressed (S241). When determining that the effective stop button has not been pressed, the main CPU 51 shifts the process to step S241 again and waits for an effective stop button pressing operation.

  On the other hand, when determining that a valid stop button has been pressed, the main CPU 51 resets the corresponding bit in the valid stop button storage area and determines an operation stop button (S242). Next, the main CPU 51 subtracts 1 from the stop button non-operating counter (S243).

  Next, the main CPU 51 performs a sliding piece number determination process which will be described later with reference to FIG. 38 (S244). Next, the main CPU 51 transmits a reel stop command to the sub control circuit 42 (S245). The reel stop command includes information such as the type of reel to be stopped and the number of sliding pieces.

  Next, the main CPU 51 determines a planned stop position based on the symbol counter and the number of sliding symbols, and stores it in the main RAM 53 (S246). In this process, the main CPU 51 adds the number of sliding symbols to the value of the symbol counter, and determines the result as a planned stop position. When the planned stop position is determined, the driving of the stepping motor is controlled by an interrupt process (see FIG. 49) described later, and the reel rotation is stopped after the symbol counter is updated to the planned stop position. .

  Next, the main CPU 51 determines a reel to be searched based on the operation stop button, and sets a scheduled stop position as symbol position data (S247). Next, the main CPU 51 refers to the symbol arrangement table, acquires a symbol code based on the symbol position data, and stores it in the symbol storage area (S248). That is, the symbols displayed on the winning determination lines 8a to 8d are specified by the reels whose rotation has been stopped.

  Next, the main CPU 51 performs a control change process which will be described later with reference to FIG. 43 (S249). Next, the main CPU 51 determines whether or not the stop button non-operation counter is 0 (S250). When determining that the stop button non-operating counter is 0, the main CPU 51 ends the reel stop control process, and moves the process to the main flow (see FIG. 27).

  On the other hand, when it is determined that the stop button non-operating counter is not 0, the main CPU 51 performs the aforementioned expected display combination storing process (see FIG. 34) (S251). In this process, priority pull-in order data is determined for each symbol position on the remaining spinning reels. When the process of S251 ends, the main CPU 51 shifts the process to S241.

[Sliding piece number determination processing]
Next, with reference to FIG. 38, the number of sliding symbols determination process will be described.

  First, the main CPU 51 selects line mask data corresponding to the operation stop button. When the left stop button 17L is pressed, the main CPU 51 selects “10000000” in which “1” is set in bit 7 corresponding to the “left reel A line” of the stop data as the line mask data. When the middle stop button 17C is pressed, “00010000” in which “1” is set in bit 4 corresponding to “middle reel A line” of the stop data is selected as the line mask data. When the right stop button 17R is pressed, “00000010” in which “1” is set to bit 1 corresponding to “right reel A line” of the stop data is selected as the line mask data.

  Next, the main CPU 51 determines whether or not the stop button non-operation counter is 2 (S272). When determining that the stop button non-operation counter is not 2, the main CPU 51 performs second and third stop processing which will be described later with reference to FIG. 39 (S273).

  On the other hand, when determining that the stop button non-operation counter is 2, the main CPU 51 determines whether or not the operation stop button is a left stop button (S274). When determining that the operation stop button is the left stop button, the main CPU 51 obtains the table selection data and the symbol counter at the time of forward pressing (S275). The forward selection table selection data is obtained with reference to the reel stop initial setting table (see FIG. 15).

  Next, the main CPU 51 refers to the first stop table for forward pressing corresponding to the table selection data for forward pressing, and acquires the number of sliding pieces for stop data and the change status based on the stop start position (S276). ).

  When determining that the operation stop button is not the left stop button in the process of S274, the main CPU 51 obtains the irregular pressing time table selection data, and sets the irregular pressing time stop table corresponding to the irregular pressing time table selection data. (S277). The irregular selection table selection data is acquired with reference to the reel stop initial setting table.

  Next, the main CPU 51 performs a line change bit check process which will be described later with reference to FIG. 40 (S278). Next, the main CPU 51 performs a line mask data change process which will be described later with reference to FIG. 41 (S279). Next, the main CPU 51 refers to the set irregular pressing stop table, and acquires the number of sliding pieces for stop data based on the line mask data and the stop start position.

  After the process of S280, after the process of S276, or after the process of S273, the main CPU 51 performs a priority pull-in control process which will be described later with reference to FIG. 42 (S281). In this process, priority draw-in ranking data corresponding to each symbol position within the range from the stop start position to the maximum number of sliding symbols “4 (or 1)” is compared, and the most appropriate number of sliding symbols is determined. When the process of S281 is completed, the main CPU 51 ends the sliding piece number determination process, and moves the process to a reel stop control process (see FIG. 37).

[Second and third stop processing]
Next, the second and third stop processing will be described with reference to FIG.

  First, the main CPU 51 determines whether or not it is during the second stop operation (S301). When determining that it is during the second stop operation, the main CPU 51 determines whether or not it is a forward press (the first stop is the left reel 3L) (S302). When the main CPU 51 determines that it is a forward press, the main CPU 51 performs a line change bit check process described later with reference to FIG. 40 (S303).

  When it is determined that the second stop operation is not performed in the process of S301 after the process of S303, or when it is determined that it is not forward pressing in the process of S302, the main CPU 51 will be described later with reference to FIG. Line mask data change processing is performed (S304). Next, the main CPU 51 performs a sliding frame number search process (S305). In this process, referring to the stop table (see FIGS. 18 and 19), the number of stop pieces for stop data is determined based on the stop start position.

  For example, when the line mask data is “00010000” corresponding to “middle reel A line”, the main CPU 51 refers to the column of “middle reel A line” of bit 4. Then, a search is sequentially performed as to whether or not the corresponding data is “1” for each symbol position within the range of the maximum number of sliding symbols from the stop start position. Next, the main CPU 51 calculates the difference from the symbol position where the corresponding data is “1” to the stop start position, and determines the calculated value as the number of stop pieces for stop data. When the process of S305 is completed, the main CPU 51 ends the second and third stop processes, and moves the process to a sliding piece number determination process (see FIG. 38).

[Line change bit check processing]
Next, the line change bit check process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not the line change bit is on (S311). In this processing, the main CPU 51 refers to the column corresponding to the “middle reel line change bit” or “right reel line change bit” in the stop table, and determines whether or not the data corresponding to the stop start position is “1”. Is determined. When determining that the data corresponding to the stop start position is not “1”, that is, that the line change bit is not ON, the main CPU 51 ends the line change bit check process.

  On the other hand, when determining that the data corresponding to the stop start position is “1”, that is, the line change bit is on, the main CPU 51 sets the B line status (S312). The B line status is data used to change the line mask data. When the process of S312 is completed, the main CPU 51 ends the line change bit check process.

[Line mask data change processing]
Next, the line mask data changing process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not the C line status is set (S321). The setting of the C line status is performed in the case of forward pressing in the second post-stop control change process described later with reference to FIG. When determining that the C line status is set, the main CPU 51 determines whether or not the operation stop button at the time of the second stop is the middle stop button (S322).

  When determining that the operation stop button at the second stop is the middle stop button in the process of S322, the main CPU 51 rotates the line mask data twice to the right (S323). If it is a forward press and the operation stop button at the second stop is the middle stop button, the operation stop button at the third stop becomes the right stop button. Therefore, the line mask data is changed from “00000010” to “10000000” by the process of S323. As a result, the column of bit 7 corresponding to the “right reel C line data” of the stop table for second and third stops (see FIG. 18) at the time of forward pressing is referred to. When the process of S323 is completed, the main CPU 51 ends the line mask data change process.

  When determining that the operation stop button at the second stop is not the middle stop button in the process of S322, the main CPU 51 rotates the line mask data twice to the left (S324). If it is a forward press and the operation stop button at the second stop is not the middle stop button, the operation stop button at the third stop becomes the middle stop button. Therefore, the line mask data is changed from “00010000” to “01000000” by the process of S324. As a result, the column of bit 6 corresponding to the “middle reel C line data” of the stop table for the second and third stops at the time of forward pressing is referred to. When the process of S324 is completed, the main CPU 51 ends the line mask data change process.

  When determining that the C line status is not set in the process of S321, the main CPU 51 determines whether or not the B line status is set (S325). When determining that the B line status is not set, the main CPU 51 ends the line mask data changing process.

  On the other hand, when determining that the B line status is set, the main CPU 51 rotates the line mask data to the right (S326). For example, when the line mask data is “00000010”, it is changed to “00000001”. As a result, the column corresponding to “B line data” in the stop table is referred to. When the process of S326 is completed, the main CPU 51 ends the line mask data change process.

[Priority pull-in control processing]
Next, the priority pull-in control process will be described with reference to FIG.

  First, the main CPU 51 sets “5” as the initial value of the priority order counter and sets “5” as the number of checks (S341). Next, the main CPU 51 determines whether or not the CT gaming state flag is on (S342).

  In the process of S342, when it is determined that the CT gaming state flag is ON, the main CPU 51 determines whether or not the operation stop button is a left stop button (S343). When determining that the operation stop button is the left stop button, the main CPU 51 changes the initial value of the priority order counter and the number of checks to “2” (S344).

  After the process of S344, when it is determined in the process of S342 that the CT gaming state flag is not on, or when the operation stop button is determined not to be the left stop button in the process of S343, the main CPU 51 displays the stop order table ( 21) is set, and the address of the priority order table is added based on the number of stop pieces for stop data (S345).

  Next, the main CPU 51 obtains the number of sliding symbols corresponding to the value of the priority order counter (S346). Next, the main CPU 51 adds the acquired number of sliding symbols to the stop start position, and acquires the priority pull-in order data from the corresponding symbol position in the expected display combination storing area (S347).

  Next, the main CPU 51 determines whether or not the priority pull-in rank data acquired in the process of S347 is greater than or equal to the previously acquired priority pull-in rank data (S348). When the main CPU 51 determines that the priority pull-in rank data acquired in the process of S347 is greater than or equal to the previously acquired priority pull-in rank data, the main CPU 51 saves the number of sliding frames acquired in the process of S346 (S349).

  After the process of S349 or when it is determined in the process of S348 that the priority pull-in rank data is not higher than the previously acquired priority pull-in rank data, the main CPU 51 decrements the number of checks by one and subtracts the priority order by one ( S350). Next, the main CPU 51 determines whether or not the number of checks is “0” (S351).

  When determining that the number of checks is not “0” in the process of S351, the main CPU 51 shifts the process to S346. On the other hand, when it is determined that the number of checks is “0”, the main CPU 51 restores the number of sliding pieces that have been evacuated (S352). When the process of S352 is completed, the main CPU 51 ends the priority pull-in control process, and moves the process to the number of sliding pieces determination process (see FIG. 38).

[Control change processing]
Next, the control change process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not it is after the third stop (S371). When determining that it is after the third stop, the main CPU 51 ends the control change process and moves the process to a reel stop control process (see FIG. 37).

  When determining that it is not after the third stop in the process of S371, the main CPU 51 determines whether or not it is after the second stop (S372). When determining that it is after the second stop, the main CPU 51 performs a second post-stop control process described later with reference to FIG. 44 (S373). When the process of S373 is completed, the main CPU 51 ends the control change process and moves the process to a reel stop control process.

  When determining that it is not after the second stop in the process of S372, the main CPU 51 determines whether or not it is a forward press (S374). When determining that it is not a forward press, the main CPU 51 ends the control change process and shifts the process to a reel stop control process. On the other hand, when the main CPU 51 determines that it is a forward push, the main CPU 51 obtains a forward push control change table (see FIG. 17) according to the forward push table change data and sets “21” as the number of searches (S375). ).

  Next, the main CPU 51 acquires a planned stop position (S376). Then, the main CPU 51 updates the change target position according to the acquired planned stop position (S377). Next, the main CPU 51 determines whether or not the updated change target position matches the planned stop position (S378). When determining that the updated change target position and the planned stop position do not match, the main CPU 51 determines whether or not the number of searches is “0”. When determining that the number of searches is “0”, the main CPU 51 ends the control change process and returns the process to the reel stop control process. On the other hand, when determining that the number of searches is not “0”, the main CPU 51 shifts the processing to S377.

  When it is determined in S378 that the change target position and the planned stop position match, the main CPU 51 determines the second and third stop table numbers for the second and third stops and the C line during forward pressing according to the change target position and the value of the line change status. Check data is acquired (S380). Next, the main CPU 51 sets a corresponding stop table based on the second and third stop table numbers for forward pressing (S381). When the process of S381 is completed, the main CPU 51 ends the control change process and moves the process to a reel stop control process (see FIG. 37).

[Control change processing after second stop]
Next, the second post-stop control change process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not it is a forward press (S401). When determining that it is not a forward press, the main CPU 51 ends the control change process after the second stop, and shifts the process to the control change process (see FIG. 43).

  When determining that it is forward pressing in the process of S401, the main CPU 51 determines whether or not the C line check data is on (S402). The C line check data is acquired by the process of S380 of the control change process (see FIG. 43).

  When determining that the C line check data is ON in the process of S402, the main CPU 51 determines whether or not the line change bit corresponding to the stop start position at the time of the second stop is ON (S403). When determining that the line change bit corresponding to the stop start position at the time of the second stop is not ON, the main CPU 51 ends the control change process after the second stop, and shifts the process to the control change process.

  When determining in step S403 that the line change bit corresponding to the stop start position at the time of the second stop is on, the main CPU 51 sets “1” to the stored second and third stop stop table numbers at the time of forward pressing. "Is added and the corresponding stop table is set (S404). Next, the main CPU 51 sets the C line status (S405). When the process of S405 is completed, the main CPU 51 ends the control change process after the second stop, and moves the process to the control change process.

[Indicator determination processing]
Next, the display combination determination process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not the data stored in the carryover combination storage area is “00000000” (S421). When the main CPU 51 determines that the data stored in the carryover combination storage area is not “00000000”, the main CPU 51 ends the display combination determination processing and moves the processing to the main flow (see FIG. 27).

  When the main CPU 51 determines that the data stored in the carryover combination storage area is “00000000” in the process of S421, the main CPU 51 determines whether the MB gaming state flag is off (S422). When it is determined that the MB gaming state flag is not off, that is, it is on, the main CPU 51 ends the display combination determination process and moves the process to the main flow.

  When determining that the MB gaming state flag is OFF in the processing of S422, the main CPU 51 determines whether or not the RT gaming state flag is OFF (S423). When the main CPU 51 determines that the RT gaming state flag is not off, that is, it is on, the main CPU 51 ends the display combination determination process and shifts the process to the main flow.

  When determining in step S423 that the RT gaming state flag is OFF, the main CPU 51 determines whether or not the display combination is “Cherry 2” (S424). When the main CPU 51 determines that the display combination is not “Cherry 2”, the main CPU 51 ends the display combination determination process and shifts the processing to the main flow.

  When determining that the display combination is “Cherry 2” in the process of S424, the main CPU 51 turns on the RT gaming state flag and sets “100” in the RT game number counter (S425). When the process of S425 is completed, the main CPU 51 ends the display combination determination process and shifts the process to the main flow.

[Bonus end check process]
Next, with reference to FIG. 46, the bonus end check process will be described.

  First, the main CPU 51 determines whether or not the MB gaming state flag is on (S441). When determining that the MB gaming state flag is on, the main CPU 51 determines whether or not the bonus end number counter is “0” (S442). When it is determined that the bonus end number counter is “0”, the main CPU 51 performs a bonus end process (S443). In this process, the main CPU 51 clears the bonus end number counter. When the bonus end number counter is “0”, it means that the number of medals paid out is 200 or more during the MB gaming state.

  Next, the main CPU 51 transmits a bonus end command to the sub-control circuit 42 (S444). The bonus end command includes information indicating that the bonus game has ended.

  After the process of S444, when it is determined in the process of S441 that the MB gaming state flag is not on, or the process of S442 determines that the bonus end number counter is not “0”, the main CPU 51 determines the SB gaming state The flag and the CT gaming state flag are turned off (S446).

Next, the RT game number counter update process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not the RT gaming state flag is on (S461). When it is determined that the RT gaming state flag is not on, the main CPU 51 ends the RT game number counter updating process and shifts the process to the main flow (see FIG. 27). On the other hand, when determining that the RT gaming state flag is ON, the main CPU 51 decrements the RT game number counter by 1 (S462).

  Next, the main CPU 51 determines whether or not the RT game number counter is “0” (S463). When the main CPU 51 determines that the RT game number counter is not “0”, the main CPU 51 ends the RT game number counter update processing and shifts the processing to the main flow. On the other hand, when it is determined that the RT game number counter is “0”, the main CPU 51 turns off the RT game state flag (S464). When the process of S464 is completed, the main CPU 51 ends the RT game number counter update process and shifts the process to the main flow.

[Bonus activation check process]
Next, the bonus operation check process will be described with reference to FIG.

  First, the main CPU 51 determines whether or not the display combination is MB or SB (S471). When it is determined that the display combination is MB or SB, the main CPU 51 refers to the bonus operation time table and performs bonus operation processing according to the display combination (S472). In this process, the MB gaming state flag or the SB gaming state flag is turned on. When the MB gaming state flag is turned on, “200” is set in the bonus end number counter.

  Next, the main CPU 51 clears the data stored in the carryover combination storage area (S473). Then, the main CPU 51 transmits a bonus start command to the sub control circuit 42 (S474). The bonus start command includes information indicating that the bonus game has started. When the process of S474 is completed, the main CPU 51 ends the bonus operation check process and moves the process to the main flow (see FIG. 27).

  When determining that the display combination is not MB or SB in the processing of S471, the main CPU 51 determines whether or not the display combination is replay (S475). When it is determined that the display combination is not replay, the main CPU 51 ends the bonus operation check process and shifts the process to the main flow.

  When determining that the display combination is replay in the processing of S475, the main CPU 51 copies the insertion number counter to the automatic insertion number counter (S476). When the process of S476 is completed, the main CPU 51 ends the bonus operation check process and shifts the process to the main flow.

[Interrupt processing under the control of the main CPU (1.1173 msec)]
Next, an interrupt process (1.1173 msec) under the control of the main CPU will be described with reference to FIG.

  Next, the main CPU 51 performs a reel control process (S483). In this process, the driving of the stepping motors 61L, 61C, 61R is controlled so that the rotation of each reel 3L, 3C, 3R is started when the start of rotation of all reels is requested, and then the reels are rotated at a constant speed. Is done. When the number of sliding symbols is determined, the symbol counter of the corresponding reel is updated by the number of sliding symbols. Then, after the updated symbol counter matches the value corresponding to the planned stop position (the symbol at the planned stop position reaches the middle stage of the display window), the rotation of the corresponding reel is decelerated and stopped. The driving of the stepping motor is controlled.

  Next, the main CPU 51 performs a lamp and 7-segment driving process (S484). In this processing, drive control of the 7-segment display 6 is performed to display the number of payouts and the number of credits. Next, the main CPU restores the register (S485). When this process ends, the main CPU 51 ends the interrupt process.

<Description of operation of sub-control circuit>
Next, the contents of the program executed by the sub CPU 81 of the sub control circuit 42 will be described with reference to FIGS.

[Main board communication task]
First, a main board communication task performed by the sub CPU 81 will be described with reference to FIG.

  First, the sub CPU 81 performs reception check of the command transmitted from the main control circuit 41 (S501). Next, when receiving a command, the sub CPU 81 extracts the type of the received command (S502).

  Next, the sub CPU 81 determines whether or not a command different from the previous one has been received (S503). When determining that the command different from the previous command has not been received, the sub CPU 81 shifts the processing to S501.

  on the other hand. When determining that a command different from the previous command has been received, the sub CPU 81 stores the message in the message queue based on the received command (S504). A message queue is a mechanism for exchanging information between processes. When the process of S504 is completed, the sub CPU 81 shifts the process to S501.

[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 (S511). Next, the sub CPU 81 determines whether or not there is a message in the message queue (S512). When it is determined that there is a message, the sub CPU 81 copies game information from the message (S513). In this process, for example, various data such as the internal winning combination, the type of reel that has stopped rotating, the display combination, and the game state flag specified by the 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. 52 (S514). In this process, depending on the type of the received command, the contents of the effect are determined and the effect data is registered.

  After the process of S514, or when determining that there is no message in the process of S512, the sub CPU 81 registers animation data (S515). Next, the sub CPU 81 registers sound data (S516). Next, the sub CPU 81 registers lamp data (S517). The registration of animation data, the registration of sound data, and the registration of lamp data are performed based on the effect data registered in the effect content determination process. When the process of S517 is completed, the sub CPU 81 shifts the process to S511.

[Production content decision processing]
Next, with reference to FIG. 52, the effect content determination process will be described.

  First, the sub CPU 81 determines whether or not it is a start command reception (S521). When it is determined that the start command is received, the sub CPU 81 extracts a random number value for effect, and determines and registers the effect number by lottery based on the internal winning combination or the like (S522). The production number is data for designating production contents to be executed this time.

  Next, the sub CPU 81 performs an effect number changing process which will be described later with reference to FIG. 53 (S523). Next, the sub CPU 81 registers the production data at the start based on the registered production number (S524). 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 the process of S524 is completed, the sub CPU 81 ends the effect content determination process, and moves the process to the effect registration task (see FIG. 51).

  When determining in step S521 that the start command is not received, the sub CPU 81 determines whether or not the reel stop command is received (S525). When it is determined that the reel stop command is received, the sub CPU 81 registers the stop effect data based on the registered effect number and stop button type (S526). When the process of S526 is completed, the sub CPU 81 ends the effect content determination process and moves the process to the effect registration task.

  When determining in step S525 that the reel stop command is not received, the sub CPU 81 determines whether or not the display command is received (S527). When it is determined that the display command is being received, the sub CPU 81 registers the display effect data based on the registered effect number (S528). When the process of S528 is finished, the sub CPU 81 ends the effect content determination process, and moves the process to the effect registration task.

  When determining in step S527 that the display command is not received, the sub CPU 81 determines whether or not the bonus start command is received (S529). When it is determined that the bonus start command is received, the sub CPU 81 registers the bonus start effect data (S530). When the process of S530 is completed, the sub CPU 81 ends the effect content determination process, and moves the process to the effect registration task.

  When determining in step S529 that the bonus start command is not received, the sub CPU 81 ends the effect content determination process, and moves the process to the effect registration task. On the other hand, when determining that it is time to receive a bonus end command, the sub CPU 81 registers effect data for ending the bonus (S532). When the process of S532 is completed, the sub CPU 81 ends the effect content determination process, and moves the process to the effect registration task.

[Direction number change processing]
Next, the effect number changing process will be described with reference to FIG.

  First, the sub CPU 81 determines whether or not the RT gaming state flag is on (S541). For example, the sub CPU 81 grasps the states of the carryover combination storage area (see FIG. 23) and the gaming state flag storage area (see FIG. 24) by the start command transmitted from the main control circuit 41. When it is determined that the RT gaming state flag is not on, the sub CPU 81 ends the effect number changing process and moves the process to an effect content determination process (see FIG. 52).

  When determining that the RT gaming state flag is ON in the process of S541, the sub CPU 81 determines whether or not the data stored in the carryover combination storage area is “00000000” (S542). When determining that the data stored in the carryover combination storage area is “00000000”, the sub CPU 81 ends the effect number change process and shifts the process to the effect content determination process.

  On the other hand, when determining that the data stored in the carryover combination storage area is not “00000000”, the sub CPU 81 changes the registered effect number to the effect number corresponding to the MB winning notification effect data ( S543). When the process of S543 is completed, the sub CPU 81 ends the effect number change process and moves the process to an effect content determination process.

  When the RT gaming state flag is ON and the data stored in the carryover combination storage area is not “00000000”, “MB” is determined as the internal winning combination during the RT gaming state. That is, in the present embodiment, when “MB” is determined as an internal winning combination during the RT gaming state, an effect number corresponding to MB winning notification effect data is registered. When the effect based on the MB winning notification effect data is executed, the MB winning notification is performed.

  FIG. 54 is an explanatory diagram for explaining MB winning notification. As shown in FIG. 54, when MB winning notification is performed, the combination of symbols corresponding to the internal winning combination of “MB” is displayed after “MB” has been determined as the internal winning combination and the RT gaming state has ended. Suggestions to do so are displayed on the liquid crystal display device 10.

The configuration and operation of the pachislot machine 1 according to the embodiment of the present invention have been described above based on the attached drawings.
According to the pachi-slot 1 according to the present embodiment, when the symbol combination of “mirror-diamond-diamond” is displayed along any of the winning determination lines 8a to 8d (the first condition is satisfied), The operation of the MB is performed and the state shifts to the MB gaming state (special gaming state). In the MB gaming state, the number of sliding pieces (second maximum delay time range) of the left reel 3L (specific display row) is set to “0” or “1”. On the other hand, the number of sliding frames (the range of the first maximum delay time) of the middle reel 3C and the right reel 3R (display rows other than the specific display row) is set to “0” to “4”.

  In the MB gaming state, the CT is operated, and the small combination is determined as the internal winning combination regardless of the result of the internal lottery. That is, in the MB gaming state, display of all symbol combinations related to medal payout is permitted.

  The MB gaming state ends when the number of medals paid out reaches 200 or when “SB” is determined as the internal winning combination. Before “SB” is determined as the internal winning combination, the game state is the MB game state and the CT game state. When the MB game state ends, only the CT game state is obtained.

  In the present embodiment, the probability that “SB” is determined as the internal winning combination is about 1/10 as described above. On the other hand, since the number of medals to be paid out by displaying the combination of symbols corresponding to the small combination is ten, at least 20 games are required for the small combination medals to be paid out to 200. In other words, the MB gaming state has a higher probability of ending when “SB” is determined as the internal winning combination than when the payout number of medals reaches 200.

  Therefore, in the MB gaming state, until “SB” is determined as the internal winning combination, many symbol combinations corresponding to the small combination (“Bell”, “Cherry 1” and “Cherry 2”) are displayed. If possible, the number of medals to be paid out increases.

  On the other hand, in the pachi-slot 1 according to the present embodiment, when the symbol combination corresponding to the internal winning combination of “Cherry 2” is displayed in the general gaming state (the second condition is satisfied), the state shifts to the RT gaming state. To do. In this RT gaming state, the probability that “Replay” is determined as an internal winning combination is increased by the lottery value changing process during RT (see FIG. 32). Therefore, when transitioning to the MB gaming state during the RT gaming state, an MB gaming state in which “replay” is easily determined as an internal winning combination.

  When “Replay” is determined as the internal winning combination, the display of the symbol combination “Replay-Replay-Replay” has the highest priority. Therefore, in the RT gaming state and the MB gaming state, it is less likely that a combination of symbols corresponding to the small role (“bell”, “cherry 1” and “cherry 2”) will be displayed, and the number of medals that can be acquired is reduced. It will decrease. That is, the average number of medals that can be acquired in the RT gaming state and the MB gaming state is smaller than the average number of medals that can be acquired in the MB gaming state that is not the RT gaming state.

  In the pachi-slot 1 of the present embodiment, when “MB” is determined as an internal winning combination during the RT gaming state, MB winning notification (see FIG. 54) is performed. When recognizing that “MB” has been determined as an internal winning combination by MB winning notification, the player performs a stop operation so that the symbol combination corresponding to “MB” is not displayed. As a result, it is possible to prevent transition to the MB gaming state during the RT gaming state.

  Then, after the RT gaming state is finished, the player displays a combination of symbols corresponding to the MB by a stop operation. As a result, the MB gaming state in which “replay” is difficult to be determined as an internal winning combination can be set, and the number of medals to be paid out can be increased as compared with the RT gaming state and the MB gaming state.

  As described above, according to the pachislot 1 according to the present embodiment, when “MB” is determined as an internal winning combination during the RT gaming state, the MB winning notification is performed, so that the player is in the RT gaming state and the MB gaming state. It is possible to perform a stop operation to avoid the state. As a result, the number of medals paid out in the MB gaming state can be increased, and the interest of the game can be enhanced.

  Also, in the pachislot 1 of the present embodiment, in the MB winning notification, the combination of symbols corresponding to the internal winning combination of “MB” is displayed after the RT gaming state ends. Therefore, the player can be surely recognized that the combination of symbols corresponding to the internal winning combination of “MB” should be displayed along the winning determination line after the RT gaming state ends.

  The pachislot machine 1 according to the above-described embodiment is configured to perform MB winning notification by displaying characters and diagrams on the display screen of the liquid crystal display device 10. However, the MB winning notification according to the present invention can be performed by sound or lamp, and can also be performed by combining sound, lamp, display, and the like.

  In the pachislot 1 according to the above-described embodiment, in the MB winning notification, a suggestion is made that a combination of symbols corresponding to the internal winning combination of “MB” is displayed after the RT gaming state ends. However, as the MB winning notification according to the present invention, only that “MB” is determined as the internal winning combination may be notified.

  In the pachi-slot 1 according to the above-described embodiment, there is one type of special internal winning combination related to the start of the middle bonus game (MB), but there are two or more types of special internal winning combinations according to the present invention. Also good.

  In the pachi-slot 1 according to the above-described embodiment, the second condition is that a combination of symbols corresponding to “Cherry 2” is displayed along the winning determination line. However, the second condition according to the present invention is not limited to this, and can be set as appropriate. For example, the second condition may be that a specific internal winning combination other than “Cherry 2” is won or that a combination of symbols corresponding to the winning internal winning combination is displayed along the winning determination line. . Two or more types of second conditions can be used.

  In the pachi-slot 1 according to the above-described embodiment, the winning determination line is four lines whose pull-in range is not limited for each stop operation. However, the present invention is not limited to this. The winning determination line according to the present invention can be set arbitrarily, and may be set to, for example, five general lines whose drawing range is limited for each stop operation.

  In that case, unless a tempering (a state where display symbols are aligned with the remaining one symbol) is possible on a plurality of winning determination lines at the same time, within the range of the first delay time (the number of sliding pieces “0” to “4”). The maximum number of symbols that can be derived is four. On the other hand, the interval between symbols arranged so as to be derivable within the range of the second maximum delay time (the number of sliding symbols “0” or “1”) is one at maximum.

  As mentioned above, although the game machine concerning one embodiment of the present invention was explained including the operation effect, the present invention is not limited to the embodiment explained here. It goes without saying that various embodiments are included without departing from the gist of the present invention described in the claims.
