Specifically, a start switch 6S, a stop switch 7S, a 1-bet switch 11S, a maximum bet switch 13S, a settlement switch 14S, a medal sensor 22S, a reel position detection circuit 50, and a payout completion signal circuit 51 are input to the microcomputer 30. Connected to the port.

  The start switch 6S detects the operation of the start lever 6, and the stop switch 7S detects that the stop buttons 7L, 7C, and 7R are pressed. The 1-bet switch 11S detects that the 1-bet button 11 is pressed, and the maximum bet switch 13S detects that the maximum bet button 13 is pressed. The settlement switch 14S detects that the settlement button 14 has been pressed.

  The medal sensor 22S detects that a medal inserted into the medal insertion slot 22 passes through a selector (not shown). The selector is a device for selecting whether or not a medal is appropriate in material, shape, and the like, and guides an appropriate medal inserted from the medal insertion slot 22 to a hopper 40 having a storage unit capable of storing a large amount of medals. A passage is formed. In the present embodiment, the “insertion operation” includes that a medal is inserted into the medal insertion slot 22 and each of the bet buttons 11 and 13 is pressed.

  The payout completion signal circuit 51 detects whether or not the number of medals discharged from the hopper 40 counted by the medal detection unit 40S has reached the payout number. The reel position detection circuit 50 receives a pulse signal from a sensor that detects the rotation of each main reel 3L, 3C, 3R (for example, an optical sensor comprising a light emitting portion and a light receiving portion), and each main reel 3L, 3C, 3R A reel index indicating one rotation is detected.

  The main reels 3L, 3C, 3R are configured to rotate once by outputting a drive pulse to the stepping motors 49L, 49C, 49R a predetermined number of times (for example, 336 times). The number of pulses output to the stepping motors 49L, 49C, 49R is counted by a pulse counter provided in the RAM 33. Each time the pulse counter counts the number of driving pulses necessary for rotation for one symbol, the main reel symbol counter provided in the RAM 33 is incremented by one. The main reel symbol counter is provided corresponding to each of the main reels 3L, 3C, 3R, and the value is cleared every time the reel position detection circuit 50 detects the reel index.

  In this embodiment, the number of symbols rotated after the reel index is detected is detected based on the value of the main reel symbol counter, and the rotation of the reel is determined based on the position where the reel index is detected. The position of each symbol in the direction is detected. Note that the number of sliding pieces, which will be described later, is managed by the value of the symbol counter that is updated after each stop button 7L, 7C, 7R is pressed. Similarly, the symbol counter is provided for the sub reel and the 4th reel 110 as well.

<Description of sub-control circuit>
Next, the circuit configuration of the sub-control circuit 72 will be described with reference to FIG.

  The sub control circuit 72 is electrically connected to the main control circuit 71 and is configured to perform communication in one direction from the main control circuit 71 to the sub control circuit 72. The sub control circuit 72 performs various processes such as determination and execution of the contents of effects based on various commands (such as a start command described later) transmitted from the main control circuit 71. The sub-control circuit 72 includes sub-reels 23L, 23C, 23R, 4th reel 110, speakers 21L, 21R and lamps 101L, 101R (including back lamps), and sub-reel film motor drive as main actuators whose operations are controlled. A circuit 339 is connected.

  The sub control circuit 72 includes a sub CPU 81, a control ROM 82, and an SDRAM 83 as main components. Based on the various commands transmitted from the main control circuit 71, the sub CPU 81 operates the sub reels 23L, 23C, 23R, the 4th reel 110, the sound output, and the sound according to the control program stored in the control ROM 82. Control the light output. The SDRAM 83 is configured as a storage unit for temporarily storing information when the sub CPU 81 executes a control program. The SDRAM 83 is provided with a storage area for storing various data such as an internal winning combination transmitted from the main control circuit 71.

  The control ROM 82 includes a program storage area and a data storage area. The program storage area stores a sub CPU control program. This sub CPU control program includes a lamp control task, a sound control task, an effect reel control task, a main board communication task (see FIG. 34) and the like which will be described later.

  The data storage area includes a table storage area, an effect data storage area, a reel data storage area, a lamp data storage area, a sound data storage area, and the like. The table storage area stores various tables, and the effect data storage area stores a plurality of types of effect data. The reel data storage area stores sub reel data and 4th reel data. The lamp data storage area stores lamp data defining a lighting pattern and the like, and the sound data storage area stores sound data such as BGM and sound effects.

  The sub-control circuit 72 includes a digital signal processor (hereinafter referred to as “DSP”) 90, an audio RAM 91, an A / D converter 88, and an amplifier 89 for controlling the sound output from the speakers 21L and 21R. It has been.

  The DSP 90 is connected to the sub CPU 81 and outputs designated sound data in accordance with a signal (command) output from the sub CPU 81. Data necessary for a task performed by the DSP 90 is expanded in the audio RAM 91. The A / D converter 88 converts sound data from digital to analog. When the sound data is converted to analog, the sound corresponding to the sound data is output from the speakers 21L and 21R via the amplifier 89 which is an amplifier.

  The sub CPU 81 includes lamps 101L and 101R (including a back lamp), a sub reel motor drive circuit 139, a sub reel position detection circuit 150, a 4 th reel motor drive circuit 239, a 4 th reel position detection circuit 250, and a sub reel. A film drive state detection circuit 350 and a sub reel film motor drive circuit 339 are connected. The sub CPU 81 controls the light output from the lamps 101L and 101R based on the light lighting pattern stored in the lamp data storage area.

  The sub-reel motor drive circuit 139, the 4th reel motor drive circuit 239, and the sub-reel film motor drive circuit 339 have functions similar to the functions of the motor drive circuit 39 in the main control circuit 71. The sub reel motor drive circuit 139 outputs a pulse for controlling the driving to the stepping motors 149L, 149C, and 149R, and controls the rotation and stop of the sub reels 23L, 23C, and 23R. The 4th reel motor drive circuit 239 outputs a pulse for controlling the drive to the stepping motor 249, and controls the rotation and stop of the 4th reel 110.

  The sub reel film motor drive circuit 339 outputs a pulse for controlling the driving to the stepping motors 349L, 349C, 349R, and controls the stop mode of the sub reel films 28L, 28C, 28R. This control is performed when changing from the normal mode to the special mode or from the special mode to the normal mode. In addition, when the stepping motors 349L, 349C, and 349R are driven, the rollers disposed inside the sub reel films 28L, 28C, and 28R are driven to rotate, and the sub reel films 28L, 28C, and 28R move. The description of the block corresponding to is omitted.

  In the gaming machine 1 of this example, the stepping motors 349L, 349C, and 349R display the first sub reel band on the outer peripheral surface of the sub reels 23L, 23C, and 23R when the replay time is not operated. When the operation is performed, it functions as a sub-reel design changing means for displaying the second sub-reel band on the outer peripheral surfaces of the sub-reels 23L, 23C, 23R.

  Further, the sub reel position detection circuit 150, the 4th reel position detection circuit 250, and the sub reel film drive state detection circuit 350 have the same functions as the functions of the reel position detection circuit 50 in the main control circuit 71. The sub reel position detection circuit 150 detects that each sub reel 23L, 23C, 23R has made one rotation. The 4th reel position detection circuit 250 detects that the 4th reel 110 has made one rotation. The sub reel film drive state detection circuit 350 detects that each sub reel film 28L, 28C, 28R has been stopped in a predetermined stop mode (normal mode or special mode).

  The SDRAM 83 of the sub control circuit 72 is provided with a symbol counter corresponding to each of the sub reels 23L, 23C, 23R and the 4th reel 110. That is, the position of the symbol in the rotation direction of each of the sub reels 23L, 23C, 23R and the 4th reel 110 is specified by the value of each symbol counter. The SDRAM 83 of the sub control circuit 72 is provided with a stop mode counter corresponding to the normal mode or the special mode corresponding to each of the sub reels 28L, 28C, 28R. For this reason, the stop mode of each sub reel film 28L, 28C, 28R is specified by the stop mode counter.

<Description of each table configuration>
Next, a configuration example of each table, symbol, and each storage area used in the gaming machine 1 of this example will be described with reference to FIGS. First, the main reel symbol arrangement table will be described with reference to FIG.

  The main reel symbol arrangement table includes symbols arranged on the surface (outer peripheral surface) of each main reel 3L, 3C, 3R and symbol positions “0” to “20” of each main reel 3L, 3C, 3R. It defines the correspondence. The symbol position is information for identifying the symbol position on the surface of the main reels 3L, 3C, 3R. On the surface of each of the main reels 3L, 3C, 3R, any of the symbols "Red 7", "Bell", "Watermelon", "Replay", "Blank (represented by clouds in this example)" Are arranged, and a symbol row composed of a total of 21 symbols is provided. Each reel 3L, 3C, 3R rotates so that the symbol row moves in the direction of arrow A in FIG.

  In the main reel symbol arrangement table, the symbol position “0” is the position where the symbol displayed in the middle of each main display window 4L, 4C, 4R when the reel index is detected. The symbol positions “0” to “20” are assigned to the positions of the symbols in the order of arrangement in the rotation direction of the main reels 3L, 3C, 3R. Therefore, by referring to the main reel symbol counter and the main reel symbol arrangement table, it is possible to specify the symbol type displayed in the middle of the main display windows 4L, 4C, 4R at that time. .

  As described above, in this example, the number and arrangement of symbols arranged on the surface of the sub reels 23L, 23C, 23R are the same as the number and arrangement of symbols arranged on the surface of the main reels 3L, 3C, 3R. ing. Therefore, the sub reel symbol arrangement table has the same configuration as the main reel symbol arrangement table. The main reel symbol arrangement table is stored in the ROM 32 of the main control circuit 71, and the sub reel symbol arrangement table is stored in the control ROM 82 of the sub control circuit 72.

  Here, an example of symbols arranged on the sub reels 23L, 23C, and 23R in this example will be described with reference to FIGS.

FIG. 8 is an example of symbols arranged on the sub reels 23L, 23C, and 23R in the normal mode. This is also called the design of the first sub reel band. The design of the first sub-reel belt is the same as the design arranged on the outer peripheral surface of the main reel described above.
FIG. 9 is an example of symbols arranged on the sub reels 23L, 23C, and 23R in the special mode. This is also referred to as a symbol of the second sub reel band. The symbol of the second sub-reel band is arranged with a symbol for notifying the player of the internal winning combination determined by the internal winning combination determining means. The first and second sub-reel bands are integrated with each other. Further, the positions of the symbols arranged on the first and second sub reel bands correspond to the symbol positions shown in the symbol arrangement table (see FIG. 7).

Here, during the replay time operation, “red 7”, “watermelon” and “watermelon” corresponding to the symbol positions “0”, “1” and “2” arranged on the first sub reel band of the sub reel film 28L are sub An operation for changing from the normal mode displayed on the display window 24L to the special mode will be described.
At this time, when the rollers 27a and 27b (see FIG. 2) are driven to rotate, the second sub reel band is displayed in the sub display window 24L so as to be visible. At this time, the symbol “W” is displayed in the sub display window 24L. For this reason, the player can know from the symbols displayed in the sub display window 24L whether or not “BB” has been won internally. However, when the replay time ends, the special mode returns to the normal mode. That is, the first sub reel band is displayed in the sub display window 24L instead of the second sub reel band.

  Next, the internal lottery table determination table used when the main CPU 31 determines the internal lottery table and the number of lotteries will be described with reference to FIG.

  The internal lottery table determination table defines information indicating the internal lottery table and information indicating the number of lotteries corresponding to the gaming state. In this example, a general gaming state, an RT gaming state, an RB gaming state, and a BB gaming state are provided as gaming states. In this example, the BB gaming state is provided as the gaming state, but since the BB gaming state and the RB gaming state are equivalent, the internal lottery table for the BB gaming state is not shown.

  The gaming state is the type of internal winning combination that may be determined in the internal lottery process (see FIGS. 27 and 28), the probability that the internal winning combination is determined in the internal lottery process, the maximum number of sliding symbols, and the bonus It is a state that is distinguished by whether or not the game is being operated. The number of sliding pieces is the number of symbols that the reels rotate until the main reels 3L, 3C, 3R and sub reels 23L, 23C, 23R corresponding to the pressed stop buttons 7L, 7C, 7R stop rotating. It is shown by. In this example, the maximum number of sliding symbols on the main reels 3L, 3C, 3R is four, and the maximum number of sliding symbols on the sub reels 23L, 23C, 23R is thirteen. The number of lotteries is the maximum number of times that the main CPU 31 subtracts a lottery value described later from one random number value extracted by the sampling circuit 37.

  Next, an internal lottery table used when the main CPU 31 determines a data pointer associated with the internal winning combination will be described with reference to FIG.

  The internal lottery table defines lottery value information and data pointer information corresponding to the winning number. The winning number is a number provided for the main CPU 31 to identify each of a plurality of types of results related to lottery performed based on one random number value extracted by the sampling circuit 37. In this example, multiple types of internal winning combinations determined in advance are divided into internal winning combinations related to winning a prize, internal winning combinations related to replays, and internal winning combinations related to bonus games, and each category is supported. Thus, a small role / replay data pointer and a bonus data pointer are provided.

  One random number value extracted by the sampling circuit 37 is stored in a predetermined area, and the value stored in this area is sequentially subtracted by a lottery value provided for each winning number. When the result of subtraction becomes a negative value, the winning number corresponding to the lottery value when the negative value is obtained by subtracting is determined as the winning number. The probability of winning each winning number (so-called winning probability) can be calculated by dividing each lottery value by the number of random values (in this example, “65536”).

  In this example, as an internal lottery table, an internal lottery table for a general gaming state shown in FIG. 11 (a), an internal lottery table for an RT gaming state shown in FIG. 11 (b), and an RB game shown in FIG. 11 (c). A state internal lottery table is provided. Thus, the internal lottery table is basically provided corresponding to the gaming state. Note that the internal lottery table may be provided according to a setting value or the like that is a value for adjusting the expected value of winning, but illustrations other than the example of the internal lottery table shown in FIG. 11 are omitted.

  Next, an internal winning combination determination table used when the main CPU 31 determines an internal winning combination based on the data pointer will be described with reference to FIG.

  The internal winning combination determination table defines a hit request flag (internal winning combination) corresponding to the data pointer. The hit request flag is basically 1-byte data in which a unique symbol combination is assigned to each bit. The winning request flag is stored in an internal winning combination storing area described later, which is a predetermined area. In this example, as the internal winning combination determination table, the small winning combination / replay internal winning combination determination table shown in FIG. 12A and the bonus internal winning combination determination table shown in FIG. 12B are provided. .

  In the gaming machine 1 of this example, “watermelon”, “bell”, “replay”, “watermelon + bell”, “BB”, and lose are provided as internal winning combinations. In this example, “watermelon” indicates a predetermined internal winning combination, and “BB” indicates a special internal winning combination relating to the operation of the bonus game. Furthermore, “Replay” indicates an internal winning combination related to the operation of replay.

  In this example, the small role / replay data pointer “4” is drawn only in the RB gaming state. However, the present invention is not limited to this and the lottery / replay data pointer “4” is also drawn in the general gaming state. It is good.

  Next, a symbol combination table used when the main CPU 31 specifies a display combination and when the main CPU 31 determines a payout number corresponding to the display combination will be described with reference to FIG.

  The symbol combination table defines a winning action flag and data indicating the number of payouts corresponding to the symbol combination. In the symbol combination table, the number of payouts is defined according to the number of input. The winning action flag is basically 1-byte data in which a unique symbol combination is assigned to each bit. The winning operation flag is provided for the main CPU 31 to identify a combination of symbols displayed along the active lines 8a to 8e (see FIG. 4).

  Here, the logical sum of the winning action flags corresponding to the combinations of symbols displayed along the active lines 8a to 8e is hereinafter referred to as “display combination”. Hereinafter, “watermelon” and “bell” are collectively referred to as “small role”, and the display of “small role” as a display role is referred to as “winning”. The display of “Replay” and “BB” as a display combination is called “operation” or “establishment”. In this example, even if “blank” is displayed along the active lines 8a to 8e, it is not said to be “winning”.

  For example, when the symbol combination “BELL-BELL-BELL” is displayed along the active lines 8a to 8e, “00000100” is determined as the winning action flag based on the symbol combination table, and the bell serves as a display combination. Become. When the inserted number is 2, 15 medals are paid out, and when the inserted number is 3, 10 medals are paid out.

  As described above, when a predetermined symbol combination is displayed along the active line, a medal is basically paid out. However, when the symbol combination related to “BB” is displayed along the active line, the operation of the big bonus game is started without paying out medals. In other words, when the display combination is BB, the gaming state is changed from the general gaming state to the BB gaming state (equivalent to the RB gaming state). In addition, when the symbol combination related to “Replay” is displayed along the active line, a state in which the start operation can be performed without performing the throwing operation, that is, a so-called replay is brought about.

  From the above, the symbol combination table basically defines information in which medals are paid out, the bonus game is started, and the benefits given to the player such as replay are associated with each other.

  Next, with reference to FIG. 14, the bonus operation time table referred to by the main CPU 31 when the operation of the bonus game is started will be described.

  The bonus operation time table is used when the main CPU 31 initializes various counters related to the start of operation of the bonus game. The bonus operation time table includes information on the game state flag stored in the game state flag storage area, information on the numerical value stored in the bonus end number counter, information on the numerical value stored in the game possible number counter, and winning Information of numerical values stored in the number counter.

  The gaming state flag is information provided for the main CPU 31 to identify the operating gaming state. The bonus end number counter is a counter provided for the main CPU 31 to count the number of medals paid out in one bonus game. The game possible number counter is a counter provided for the main CPU 31 to count the number of remaining games that can be played in one regular bonus game, the so-called game possible number. The winable number counter is a counter provided for the main CPU 31 to count the number of remaining games in which a combination of symbols related to winning can be displayed in one regular bonus game, the so-called winable number. .

  Next, a main reel stop table group determination table used when the main CPU 31 determines a main stop table group based on the data pointer will be described with reference to FIG.

  The main reel stop table group determination table defines a main stop table group corresponding to the data pointer, the value stored in the carryover combination storage area, and the gaming state. Each main stop table group is composed of a plurality of stop tables that are used when the main CPU 31 determines the sliding piece number determination data in the reel stop control process (see FIG. 29).

  For example, in a general gaming state where the value stored in the carryover combination storage area is “0” (when there is no carryover combination), if the data pointer is “1” (the internal winning combination is “watermelon”), the main CPU 31 The “main stop table group 2” is determined as the main stop table group to be used. Then, the main CPU 31 selects a stop table to be used from the “main stop table group 2” based on the pressed stop buttons 7L, 7C, and 7R.

  Next, with reference to FIG. 16, the stop table used when the main CPU 31 determines the sliding piece number determination data will be described.

  The stop table defines information on the number of pieces of sliding piece determination data corresponding to the symbol position data indicating the stop start position for each of the main reels 3L, 3C, 3R. The sliding piece number determination data is information provided for the main CPU 31 to determine an appropriate number of sliding pieces from a plurality of predetermined sliding pieces (0 to 4 pieces).

  FIG. 16 shows the watermelon stop table A of the “main stop table group 2”. In the stop table A for watermelon, among the symbols arranged on the left main reel 3L and the right main reel 3R, “watermelon” arranged continuously is displayed with high probability on the main display windows 4L and 4R. It is configured. For example, if the stop button 7L is pressed while any of the symbols of the symbol positions “8” to “13” of the rotating left main reel 3L is displayed in the middle stage of the main display window 4L, the left main reel 3L It stops in a state where the symbols at symbol positions “12” and “13” are displayed on the main display window 4L. That is, two “watermelons” which are symbols of symbol positions “12” and “13” of the left main reel 3L are displayed on the main display window 4L.

Here, selection of the stop table by the main CPU 31 will be described.

  First, it is assumed that the first stop operation is performed on the left main reel 3L when the symbol of the symbol position “14” of the rotating left main reel 3L is displayed in the middle of the main display window 4L. At this time, the main CPU 31 determines the sliding piece number determination data with reference to the watermelon stop table A. Therefore, the left main reel 3L stops in a state where the symbol (“replay”) at the symbol position “14” is displayed in the middle of the main display window 4L. Then, “watermelon” which is a symbol of symbol position “13” of the left main reel 3L is displayed in the lower part of the main display window 4L.

  Next, it is assumed that the second stop operation is performed on the right main reel 3R when the symbol of the symbol position “14” of the rotating right main reel 3R is displayed in the middle of the main display window 4R. At this time, the main CPU 31 determines the sliding piece number determination data with reference to the watermelon stop table A. Therefore, the right main reel 3R stops in a state where the symbol (“replay”) at the symbol position “14” is displayed in the middle of the main display window 4R. Then, “watermelon” which is a symbol of symbol position “13” of the right main reel 3R is displayed in the lower part of the main display window 4R.

  In a state where the second stop operation has been completed, the symbol “watermelon” is displayed in the lower stage of the sub display windows 4L and 4R. However, when the third stop operation is performed on the middle main reel 3C, if the slip piece number determination data is determined with reference to the watermelon stop table A, the "watermelon" symbol is displayed in the lower stage of the sub display window 4C. Thus, the middle main reel 3C cannot be stopped.

  This is because, in the watermelon stop table A, the sliding piece number determination data is set so that the symbols of “watermelon” (symbol positions “7” and “14”) are displayed in the middle of the main display window 4C. is there. Therefore, the main CPU 31 uses the “main stop table group” as the stop table in which the slip piece number determination data is set so that the symbol positions “7” and “14” of the middle main reel 3C are displayed in the lower stage of the main display window 4C. Select from “2” and refer to it. As a result, when the third stop operation is performed on the middle main reel 3C, the “watermelon” symbol can be displayed in the lower stage of the main display window 4C.

  Next, an example of an internal winning combination storage area (display combination storage area), a carryover combination storage area, and a game state flag storage area will be described with reference to FIG.

  FIG. 17A shows an internal winning combination storing area in which data indicating a hit request flag is stored. For example, when “bell” is determined as the internal winning combination in the internal lottery process (see FIGS. 27 and 28), “1” is stored in bit 2 of the internal winning combination storing area. That is, “00000010” is stored in the internal winning combination storing area. Although the illustration of the display combination storage area in which data related to the display combination is stored is omitted, this display combination storage area has the same structure as the internal winning combination storage area.

  FIG. 17B shows a carryover combination storage area in which data relating to a carryover combination is stored. For example, when “BB” is determined as the internal winning combination in the internal lottery process, “1” is stored in bit 3 of the carryover combination storing area. That is, “00001000” is stored in the carryover combination storage area. Here, when the carryover combination is permitted over one or a plurality of games that a combination of symbols corresponding to the data pointer determined in the internal lottery process described later is allowed to be displayed along one or more games, the data pointer Is provided for the main CPU 31 to identify. The case where there is a carryover combination is hereinafter referred to as “between flags”, and the case where there is no carryover combination is hereinafter referred to as “non-flagging”.

  FIG. 17C shows a game state flag storage area in which data indicating the game state flag is stored. In the content column shown in FIG. 17C, the content of the game state flag corresponding to each bit of the game state flag storage area is shown. For example, when the value stored in the gaming state flag storage area is “00000001”, it indicates that the BB gaming state flag is on. Note that the BB gaming state flag being on indicates that the BB gaming state is operating.

  In this example, if the BB gaming state is activated, the gaming state flag storage area stores “1” in bit 0 and bit 1 because it is the RB gaming state. That is, the game state flag storage area is “00000011”. On the other hand, if “0” is stored in bit 0 corresponding to the BB gaming state flag in the gaming state flag storage area and “0” is stored in bit 1 corresponding to the RB gaming state flag, It shows that there is.

  Next, an example of an effective stop button storage area and an operation stop button storage area will be described with reference to FIG.

  FIG. 18A shows an effective stop button storage area in which data indicating stop buttons 7L, 7C, and 7R that are effective to be pressed, that is, so-called effective stop buttons are stored. For example, if the left stop button 7L is not yet pressed, that is, an effective stop button, “1” is stored in bit 0 of the effective stop button storage area. The main CPU 31 identifies stop buttons 7L, 7C, and 7R that have not yet been pressed based on the data stored in the effective stop button storage area.

  FIG. 18B shows an operation stop button storage area in which data indicating stop buttons 7L, 7C, and 7R that have been pressed this time, that is, so-called operation stop buttons, are stored. For example, when the left stop button 7L is a stop button pressed this time, that is, an operation stop button, “1” is stored in bit 0 of the operation stop button storage area. Based on the data stored in the operation stop button storage area, the main CPU 31 identifies the stop buttons 7L, 7C, and 7R that have been pressed this time.

  Next, the 4th reel symbol arrangement table will be described with reference to FIG.

  The 4th reel symbol arrangement table is stored in the control ROM 82 of the sub-control circuit 72. This 4th reel symbol arrangement table defines the correspondence between symbols arranged on the surface (outer peripheral surface) of the 4th reel 110 and these symbol positions “0” to “4”. This symbol position is information for identifying the symbol position on the surface of the 4th reel 110.

  On the surface of the 4th reel 110, “blank”, “CHANCE”, “WIN”, “LOSE”, and “?” Are arranged for the symbol positions “0” to “4”, respectively. Any one of these five symbols is displayed on the 4th display window 112. In the 4th reel symbol arrangement table, the symbol position “0” is the position where the symbol displayed in the 4th display window 112 when the reel index is detected. Thereby, the type of the symbol displayed on the 4th display window 112 can be specified by referring to the symbol counter for the 4th reel and the symbol arrangement table for the 4th reel.

  Next, a sub reel stop table group determination table used when the sub CPU 81 determines a sub stop table group based on a data pointer will be described with reference to FIG.

  The sub reel stop table group determination table is used in a received command analysis process (see FIG. 36) described later. This sub reel stop table group determination table defines sub stop table groups corresponding to the data pointer, the value stored in the carryover combination storage area, and the gaming state. Each sub stop table group is composed of a plurality of stop tables used when determining the number of sliding piece determination data when stopping the sub reels 23L, 23C, and 23R.

In this example, the number and arrangement of symbols arranged on the surface of the sub reels 23L, 23C, 23R are the same as the number and arrangement of symbols arranged on the surface of the main reels 3L, 3C, 3R. Therefore, the sub stop table group and the main stop table group are configured by a common stop table.
When the number or arrangement of symbols arranged on the surface of the sub reels 23L, 23C, 23R and the main reels 3L, 3C, 3R are different, the sub stop table group and the main stop table group are configured by different stop tables. The

  Next, the effect data table will be described with reference to FIG.

  The production data table defines production data (production contents) according to the production number. The timing of executing each effect data is as follows: start operation (when the start lever 6 is operated), first stop, second stop, third stop, and after all stops (after the third stop) Is stipulated. The effect number is lottery based on an effect lottery table (see FIG. 22) described later.

  For example, when the production data corresponding to the production number “9” is executed, first, at the start operation, the start sound 1 is output and the “CHANCE” symbol of the 4th reel 110 is displayed in the 4th display window 112. The

  Next, an effect lottery table used when the sub CPU 81 randomizes the effect number will be described with reference to FIG.

  The effect lottery table prescribes the probability of winning the effect number corresponding to the value stored in the carryover combination storage area and the internal winning combination. In the effect lottery table, the probability of winning the effect number when the internal winning combination is “losing”, “bell”, and “replay” is not shown. For example, if the value stored in the carryover combination storage area is “0” (when there is no carryover combination) and the internal winning combination is “watermelon”, the probability that the production number “9” is won is 96 / 128 (about 75%).

  Next, the special sub reel stop mode determination table will be described with reference to FIG.

  The sub reels 23L, 23C, and 23R display the symbols so as to be visible from the display windows 24L, 24C, and 24R in any of a normal mode and a special mode. When the RT is in operation, the sub reels 23L, 23C, 23R are in a special mode, and the symbols of the second sub reel band are displayed on the display windows 24L, 24C, 24R. When the RT is not operating, the normal mode is set, and the symbols of the first sub reel band are displayed on the display windows 24L, 24C, and 24R. In the normal mode, the main reels 3L, 3C, 3R and the sub reels 23L, 23C, 23R display the same symbol.

  Also, the stop mode of the special sub-reel depends on whether the carryover combination storage area (see FIG. 17B) is zero (“00000000”) or non-zero (“00001000”) during RT operation. Different. Moreover, the stop mode of the special sub reel also varies depending on the internal winning combination.

  For example, when RT is in operation and the carryover combination storage area is zero and “watermelon” is determined as the internal winning combination, “CHANCE” is set to 96/128 in the sub display windows 24L, 24C, and 24R. Displayed with probability. For this reason, the player looks at “CHANCE”, anticipates that “watermelon” has been determined as an internal winning combination, and aims to win “watermelon”.

<Description of main control circuit operation>
Next, the operation of the main control circuit 71 will be described with reference to the flowcharts shown in FIGS.

  First, the main flowchart showing the main processing executed by the main CPU 31 will be described with reference to the flowchart shown in FIG.

  First, the main CPU 31 performs an initialization process (step S1). As an initialization process, the main CPU 31 checks whether the RAM 33 is normal, initializes an input / output port, and the like. When the initialization process ends, the main CPU 31 deletes the information in the designated storage area (step S2). For example, the main CPU 31 clears data stored in the internal winning combination storing area, the operation stop button storing area, and the effective stop button storing area.

  When the data stored in the designated storage area is erased by the process of step S2, the main CPU 31 performs a bonus operation monitoring process (see FIG. 25) (step S3).

  Next, the main CPU 31 performs medal reception / start check processing (see FIG. 26), which will be described later (step S4). After the medal acceptance / start check process, the main CPU 31 extracts a random value and stores the extracted random value in the random value storage area of the RAM 33 (step S5). Specifically, the main CPU 31 extracts a random value from the range of “0” to “65535” by the random number generator 36 and the sampling circuit 37, and stores the extracted random value in the random value storage area of the RAM 33. The random value extracted by the main CPU 31 is used in the internal lottery process.

  Next, the main CPU 31 performs a gaming state monitoring process (step S6). In the gaming state monitoring process, the main CPU 31 edits the gaming state information for identifying the gaming state in the current unit game based on the BB operating flag and the RB operating flag, and sets it in the RAM 33.

  Next, the main CPU 31 performs an internal lottery process (see FIGS. 27 and 28) (step S7). In the internal lottery process, the main CPU 31 determines an internal winning combination with reference to an internal lottery table determination table (see FIG. 10), an internal lottery table (see FIG. 11), and an internal winning combination determination table (see FIG. 12).

  Next, the main CPU 31 refers to the main reel stop table group determination table (see FIG. 15), and determines the main stop table group based on the gaming state and the internal winning combination determined in the process of step S7 (see FIG. 15). Step S8).

  Next, the main CPU 31 sets a start command in a communication data storage area provided in the RAM 33 (step S9). The start command includes information such as a gaming state and an internal winning combination. Thereby, the sub-control circuit 72 can produce an effect according to the start operation.

  Next, the main CPU 31 requests the start of rotation of all reels (step S10). In this process, the main CPU 31 stores “1” in bits 0 to 2 of the effective stop button storage area corresponding to each of the stop buttons 7L, 7C, and 7R. By storing “1” in bits 0 to 2 of the effective stop button storage area, the pressing operation of the three stop buttons 7L, 7C, and 7R becomes effective. When the start lever 6 is operated, the main CPU 31 rotates the main reels 3L, 3C, 3R via the motor drive circuit 39.

  Next, the main CPU 31 performs a reel stop control process (see FIG. 29) (step S11). In the reel stop control process, the main CPU 31 stops the rotation of the main reels 3L, 3C, 3R based on a stop signal output from the stop switch 7S by the stop operation of the player.

  Next, the main CPU 31 refers to the symbol combination table (see FIG. 13), and determines the display combination and the number of medals to be paid out based on the symbol combination displayed along the active lines of the main display windows 4L, 4C, 4R. Determine (step S12). In this process, the main CPU 31 determines the display combination based on the code number of the symbols displayed along the active line and the symbol combination table. Further, the main CPU 31 updates the display combination storing area and updates the information on the number of payouts corresponding to the display combination.

  Specifically, the main CPU 31 determines whether or not a combination of symbols corresponding to the determined internal winning combination is displayed along the active line corresponding to the active line counter. Thereafter, the effective line counter is decremented by “1”, and this process is repeated until the effective line counter becomes “0”. Since “5” is stored in the valid line counter by the medal acceptance / start check process (see FIG. 26), the main CPU 31 displays a display combination for each of the five valid lines 8a to 8e (see FIG. 4). Determine the number of medals to be paid out.

  When “replay” is determined as the display combination, the main CPU 31 stores the number of medals that can be replayed (“3” in the general gaming state) in the automatic insertion counter. When “Replay” is the display combination, the automatic insertion counter counts the number of medals to be automatically inserted in the next game.

  When the display combination and the number of payouts are determined, the main CPU 31 sets the display combination command in the communication data storage area provided in the RAM 33 (step S13). The display combination command includes information on the determined display combination and the number of medals to be paid out.

  Next, the main CPU 31 performs a medal payout process for paying out medals based on the determined medal payout number (step S14). In the medal payout process, the main CPU 31 updates the credit counter set in the RAM 33 based on the payout number in the credit mode. When the credit counter is updated, the value of the credit counter is displayed on the credit display unit 18b. In the payout mode, the main CPU 31 controls the hopper 40 by the hopper drive circuit 41 to pay out medals.

  Next, when the bonus end number counter is “1” or more, the main CPU 31 subtracts the medal payout number determined in step S13 from the value of the bonus end number counter (step S15).

  Next, the main CPU 31 determines whether or not the BB gaming state flag is on (step S16). When determining that the BB gaming state flag is on, the main CPU 31 performs a bonus end check process (see FIG. 30) (step S17), and returns the process to step S2.

  On the other hand, when the main CPU 31 determines that the BB gaming state flag is OFF, it performs RT control processing (see FIG. 31) (step S18). Then, the main CPU 31 performs a bonus operation check process (see FIG. 32) (step S19). When the bonus operation check process ends, the main CPU 31 returns the process to step S2 again.

  In this manner, the main CPU 31 executes the processes from steps S2 to S19 as processes in one unit game. When the processing up to step S17 or step S19 is completed, the processing proceeds to step S2 in order to execute processing in the next unit game.

  Next, with reference to FIG. 25, the bonus operation monitoring process performed under the control of the main CPU 31 will be described. The bonus operation monitoring process is a process for continuing the RB gaming state during the BB gaming state.

  First, the main CPU 31 determines whether or not the BB gaming state flag (see FIG. 17C) is on (step S31). When determining that the BB gaming state flag is not on, the main CPU 31 ends the bonus operation monitoring process and moves the process to the main flow (see FIG. 24).

  On the other hand, when determining that the BB gaming state flag is on, the main CPU 31 determines whether or not the RB gaming state flag is on (step S32). When the main CPU 31 determines that the RB gaming state flag is on, the main CPU 31 ends the bonus operation monitoring process and shifts the process to the main flow.

  On the other hand, when the main CPU 31 determines that the RB gaming state flag is not ON, the main CPU 31 performs RB operation processing based on the bonus operation table (see FIG. 14) (step S33). Specifically, the main CPU 31 sets “8” in the possible game number counter and the possible winning number counter, respectively, and turns on the RB gaming state flag. Thereafter, the main CPU 31 ends the bonus operation monitoring process and shifts the process to the main flow.

  Next, with reference to FIG. 26, a medal acceptance / start check process performed under the control of the main CPU 31 will be described. The medal acceptance / start check process is a process for detecting a medal insertion operation and a game start operation performed by the player.

  First, the main CPU 31 determines whether or not the value of the automatic insertion counter is “0” (step S41). When determining that the value of the automatic insertion counter is not “0”, the main CPU 31 proceeds to the process of step S43. Here, the automatic insertion counter is data for identifying whether or not “replay” has been established in the previous unit game. When “replay” is established, medals for the number of replayable games are automatically inserted. On the other hand, when the main CPU 31 determines that the value of the automatic insertion counter is “0”, the main CPU 31 permits passage of medals (step S42), and proceeds to the processing of step S45.

  On the other hand, when determining that the value of the automatic insertion counter is not “0”, the main CPU 31 copies the automatic insertion counter to the insertion number counter (step S43) and clears the automatic insertion counter (step S44). Here, the inserted number counter is data for counting game values (for example, medals).

  When the passage of medals is permitted in the process of step S42, or when the automatic insertion counter is cleared in the process of step S44, the main CPU 31 sets “3” as the maximum value of the medal insertion number counter (step S45). .

  Next, the main CPU 31 determines whether or not the BB gaming state flag is on (step S46). When the main CPU 31 determines that the BB gaming state flag is not on, the main CPU 31 proceeds to the process of step S48.

  On the other hand, when determining that the BB gaming state flag is on, the main CPU 31 changes the maximum value of the medal insertion number counter to “2” (step S47). In this example, the number of inserted medals in the general gaming state is defined as “3”, and the number of inserted medals in the RB gaming state is defined as “2”. Therefore, the main CPU 31 sets the maximum value of the number of medals inserted according to the gaming state by the processes of steps S45 and S47.

  When it is determined in step S46 that the BB gaming state flag is not on, or when the maximum value of the inserted number counter is changed to “2” in step S47, the value of the inserted number counter is determined in step S55 described later. When it is determined that it is not the maximum value, or when it is determined that the start switch 6S is not turned on in the process of step S56 described later, the main CPU 31 determines whether or not a medal has passed (step S48).

  When determining that the medal has not passed, the main CPU 31 proceeds to the process of step S54. On the other hand, when determining that the medal has passed, the main CPU 31 determines whether or not the inserted number counter is the maximum value (step S49).

  When determining that the inserted number counter is the maximum value in the process of step S49, the main CPU 31 adds “1” to the value of the credit counter (step S53), and proceeds to the process of step S54. Here, the credit counter is data for counting the number of credited medals.

  On the other hand, when determining that the insertion number counter is not the maximum value, the main CPU 31 adds “1” to the value of the insertion number counter (step S50).

  Next, the main CPU 31 stores “5” in the valid line counter (step S51). The valid line counter is data for specifying the number of valid lines, and the display combination is searched based on the valid line counter.

  Next, the main CPU 31 sets a medal insertion command in the communication data storage area provided in the RAM 33 (step S52), and proceeds to the processing of step S54. The medal insertion command includes information on the number of inserted medals.

  When it is determined that the medal has not passed in the process of step S48, when the medal insertion command is set in the process of step S52, or when the credit counter is incremented by "1" in the process of step S53, the main CPU 31 Is checked (step S54). Specifically, the main CPU 31 identifies the bet switch that is turned on among the bet switches 11 and 13. Then, based on the inserted number counter and the maximum values of the credit counter and the inserted number counter, a value to be added to the inserted number counter is calculated to update the inserted number counter.

  Note that the main CPU 31 sets “5” to the active line counter when it is determined that the medal has not passed in the process of step S48 and any of the bet switches is turned on. Further, the value of the inserted number counter is updated based on the type of the bet switch that is turned on, and a medal insertion command including information indicating the value of the inserted number counter is set in a communication data storage area provided in the RAM 33. .

  Next, the main CPU 31 determines whether or not the value of the insertion number counter is the maximum value (step S55). When the main CPU 31 determines that the value of the insertion number counter is not the maximum value, the main CPU 31 proceeds to the process of step S48. On the other hand, when determining that the value of the insertion number counter is the maximum value, the main CPU 31 determines whether or not the start switch 6S is on (step S56).

  Next, when the main CPU 31 determines that the start switch 6S is not on, the main CPU 31 proceeds to the processing of step S48. On the other hand, when the main CPU 31 determines that the start switch 6S is on, the main CPU 31 prohibits the passage of any more medals (step S57), ends the medal acceptance / start check process, and the process proceeds to the main flow (FIG. 24). To see).

  Next, an internal lottery process performed under the control of the main CPU 31 will be described with reference to the flowcharts of FIGS. 27 and 28. The internal lottery process is a process for determining an internal winning combination depending on the gaming state or the like.

  First, the main CPU 31 obtains a game state flag, and determines the type of the internal lottery table and the number of lotteries according to the game state based on the internal lottery table determination table (see FIG. 10) (step S61). That is, the number of lotteries is set to “5” in the general gaming state or the RT gaming state, and the number of lotteries is set to “1” in the RB gaming state.

  Next, the main CPU 31 determines whether or not the carryover combination storage area (see FIG. 17B) is “00000000” (step S62). That is, the main CPU 31 determines whether or not the gaming machine 1 is in the BB carryover state. Normally, in the general gaming state, the probability that “BB” wins internally is low, and the probability that “BB” is established is also low. For this reason, in order to prevent the internally won “BB” from being expired in one game, a carryover combination storage area is provided in which “BB” can be carried over as a carryover for a plurality of games. The carryover combination stored in the carryover combination storage area is not cleared when “BB” is established, that is, until the operation of the big bonus game is started.

  When the main CPU 31 determines that the carryover combination storage area is “00000000”, that is, determines that the carryover combination storage area is not in the BB carryover state, the main CPU 31 proceeds to the process of step S64.

  When the main CPU 31 determines that the carryover combination storage area is not “00000000”, that is, the BB carryover state, the main CPU 31 subtracts “1” from the number of lotteries in the internal lottery table for the general gaming state (step S63). Here, the reason why “1” is subtracted from the number of lotteries in the internal lottery table for the general gaming state is that, when the identifier of BB is stored in the carryover combination storage area, the lottery of “BB” is not performed again. That is, in the BB carryover state, the number of lotteries in the internal lottery table for the general gaming state is only four from the winning numbers 1 to 4 in the internal winning combination determination table (see FIG. 12). In addition, since being in the BB carryover state is not the RB gaming state, “1” is not subtracted from the number of lotteries in the internal lottery table for the RB gaming state.

  After subtracting “1” from the number of lotteries in the internal lottery table for general gaming state in the process of step S63 or when determining in the process of step S62 that the carryover combination storage area is “00000000”, the main CPU 31 Then, the random value stored in the random value storage area is acquired and set as random number data (step S64).

  Next, the main CPU 31 sets the same value as the number of lotteries as a winning number, and acquires a lottery value corresponding to the winning number with reference to the internal lottery table (step S65). Subsequently, the main CPU 31 subtracts the lottery value from the random number data (step S66).

  Next, the main CPU 31 determines whether or not a digit has been obtained as a result of subtracting the lottery value from the random number data (step S67). In other words, it is determined whether or not the result of the calculation in step S66 is negative. When it is determined that a digit has been made, the main CPU 31 obtains the small role / replay data pointer and the bonus data pointer (step S71), and proceeds to the processing of step S72.

  On the other hand, when it is determined in step S67 that no digit is performed, the main CPU 31 subtracts “1” from the number of lotteries (step S68). At this time, the result of subtracting the lottery value from the random number data in the process of step S66 is set as new random number data. Subsequently, the main CPU 31 determines whether or not the number of lotteries is “0” (step S69).

  When it is determined in step S69 that the number of lotteries is not “0”, the main CPU 31 shifts the process to step S65 again. That is, the main CPU 31 sets the same value as the number of lotteries as the winning number, and acquires the lottery value corresponding to the winning number with reference to the internal lottery table. On the other hand, when it is determined in step S69 that the number of lotteries is “0”, the main CPU 31 sets “0” as the small role / replay data pointer and bonus data pointer (step S70).

  When “0” is set as the data pointer in the process of step S70, or when the data pointer is acquired in the process of step S71, the main CPU 31 determines the small winning combination / replay internal winning combination determination table (FIG. 12A). The internal winning combination (winning request flag) is acquired based on the small combination / replay data pointer (step S72). Subsequently, the main CPU 31 stores the acquired internal winning combination (winning request flag) in the corresponding internal winning combination storing area (step S73).

  Next, the main CPU 31 determines whether or not the carryover combination storage area is “00000000” (step S74). When determining that the carryover combination storage area is not “00000000”, the main CPU 31 proceeds to the process of step S77.

  On the other hand, when it is determined that the carryover combination storage area is “00000000”, the main CPU 31 refers to the bonus internal winning combination determination table (see FIG. 12B) and determines the internal winning combination based on the bonus data pointer. A combination (winning request flag) is acquired (step S75). Subsequently, the main CPU 31 stores the acquired internal winning combination (winning request flag) in the carryover combination storage area (step S76).

  When the winning request flag acquired in the process of step S76 is stored in the carryover combination storage area, or when it is determined in step S75 that the carryover combination storage area is not “00000000”, the main CPU 31 stores it in the carryover combination storage area The acquired data is acquired, and the logical sum of this data and the data stored in the internal winning combination storing area is stored in the internal winning combination storing area (step S77). Thereafter, the main CPU 31 ends the internal lottery process and shifts the process to the main flow (see FIG. 24).

  Next, the reel stop control process performed under the control of the main CPU 31 will be described with reference to the flowchart of FIG. The reel stop control process is a process for stopping the rotation of the main reels 3L, 3C, and 3R based on the internal winning combination or the timing of the stop operation by the player.

  First, the main CPU 31 determines whether or not the effective stop buttons 7L, 7C, and 7R are pressed (step S81). When the main CPU 31 determines that the valid stop buttons 7L, 7C, and 7R are not pressed, the main CPU 31 shifts the process to step S81 again and waits for a stop button pressing operation.

  On the other hand, when the main CPU 31 determines that the valid stop button stop buttons 7L, 7C, and 7R have been pressed, the main CPU 31 invalidates the pressing operation of the operation stop button that is the stop button that has been pressed (step S82). . That is, the main CPU 31 sets the value of the effective stop button storage area (see FIG. 18A) corresponding to the stop button for which the pressing operation has been performed to “0”, and the operation corresponding to the stop button for which the pressing operation has been performed. The value of the stop button storage area (see FIG. 18B) is set to “1”.

  Next, the main CPU 31 selects a stop table based on the operation stop button from the determined stop table group (see step S8 in FIG. 24), and stores the number of sliding piece determination data corresponding to the main reel symbol counter. (Step S83). The sliding piece number determination data is stored in the RAM 33.

  Next, the main CPU 31 sets “5” as the number of checks (step S84). This is because the maximum number of sliding pieces of each main reel 3L, 3C, 3R is set to “4”. That is, by setting the number of checks to “5”, the number of sliding pieces “0” to “4” is checked.

  Next, the main CPU 31 searches for a symbol position having a higher priority within the range of the number of checks from the symbol position corresponding to the main reel symbol counter (step S85). For example, “BB” is determined as the internal winning combination in the general gaming state, and as a result of the rotation of the left main reel 3L and the middle main reel 3C being stopped, the “red 7” along the bottom effective line 8d (see FIG. 4). ”Is displayed. Assume that the stop start position of the rotating right main reel 3R is “11” (see FIG. 7). At this time, among the symbol positions “11” to “15” of the right main reel 3R, the symbol position “12” capable of displaying the symbol “red 7” along the bottom effective line 8d has the highest priority. It is determined as a symbol position having a higher rank.

  Next, the main CPU 31 determines the number of sliding symbols based on the stored number of sliding symbol determination data and the result of the searched symbol position having the higher priority (step S86). As a result, the main reels 3L, 3L, 3R, and 3R are displayed so that symbols at symbol positions corresponding to the value obtained by adding the value determined as the number of sliding symbols to the stop start position are displayed in the middle of the main display windows 4L, 4C, 4R. The rotation of 3C and 3R is stopped.

  Next, the main CPU 31 performs a stop control position waiting process (step S87). Specifically, the main CPU 31 performs the reel stop control process until a reel control process (step S135) of an interrupt process (see FIG. 33) described later is performed based on the stop control position determined by the determined number of sliding symbols. Stop. The main CPU 31 resumes the reel stop control process when the corresponding reel is stopped by the reel control process of the interrupt process.

  Next, the main CPU 31 sets a reel stop command in a communication data storage area provided in the RAM 33 (step S88). The reel stop command includes data indicating the type of the stopped reel, information on a stop control position corresponding to the value of the symbol counter, and the like.

  Next, the main CPU 31 determines whether or not there is a stop button for which the pressing operation is valid (step S89). That is, the main CPU 31 determines whether or not any of bits 0 to 2 of the effective stop button storage area is “1”. When determining that there is a stop button for which the pressing operation is valid, the main CPU 31 shifts the process to step S81 again and repeats the reel stop control process. On the other hand, when the rotation of all the main reels 3L, 3C, 3R is stopped and it is determined that there is no stop button for which the pressing operation is effective, the main CPU 31 ends the reel stop control process, and the process is performed in the main flow (FIG. To see).

  Next, the bonus end check process performed under the control of the main CPU 31 will be described with reference to the flowchart of FIG. The bonus end check process is a process for performing a check for ending the bonus game when a bonus game end condition is satisfied.

  First, the main CPU 31 determines whether or not the value of the bonus end number counter is “0” (step S101). In this example, when the bonus operation is started, “345” is set to the value of the bonus end number counter by the bonus operation check process (see FIG. 32). Each time a prize is won, the payout number is subtracted from the value of the bonus end number counter, and when the value of the bonus end number counter becomes “0” (a negative value is regarded as “0”), the bonus is increased. finish.

  When determining that the value of the bonus end number counter is not “0” in the process of step S101, the main CPU 31 proceeds to the process of step S104. On the other hand, when determining that the value of the bonus end number counter is “0” in the process of step S101, the main CPU 31 performs a process at the end of BB (step S102). Specifically, the main CPU 31 turns off the BB operating flag that is on, and turns off the RB operating flag when the RB operating flag is on.

  Next, the main CPU 31 sets a bonus end command in the communication data storage area provided in the RAM 33 (step S103), and shifts the processing to the main flow (see FIG. 24). The bonus end command includes information indicating that the bonus game has ended.

  When the main CPU 31 determines that the value of the bonus end number counter is not “0” in the process of step S101, the main CPU 31 subtracts “1” from the values of the winning possible number counter and the possible gaming number counter (step S104). Subsequently, the main CPU 31 determines whether or not the subtracted winning count counter and the possible gaming count counter are “0” (step S105).

  When the main CPU 31 determines that the values of the winable number counter and the possible game number counter are not “0”, the main CPU 31 ends the bonus end check process and shifts the process to the main flow. On the other hand, when it is determined that the value of the winning possible number counter and the possible number of games counter is “0”, the main CPU 31 performs processing at the end of RB (step S106). Specifically, the main CPU 31 performs processing such as turning off the RB operating flag. When the main CPU 31 performs the RB end process, the main CPU 31 ends the bonus end check process, and moves the process to the main flow.

  Next, RT control processing performed under the control of the main CPU 31 will be described with reference to the flowchart shown in FIG.

  First, the main CPU 31 determines whether or not the RT gaming state flag is on (step S111). When it is determined that the RT gaming state flag is OFF, the main CPU 31 ends the RT control process and returns the process to the main flow.

  On the other hand, when determining in step S111 that the RT gaming state flag is ON, the main CPU 31 subtracts “1” from the RT gaming number counter (step S112). Then, the main CPU 31 determines whether or not the RT game number counter is “0” (step S113). When determining that the RT game number counter is not “0”, the main CPU 31 ends the RT control process and returns the process to the main flow.

  On the other hand, when determining that the value of the RT game number counter is “0” in the process of step S113, the main CPU 31 turns off the RT game state flag (step S114), ends the RT control process, and performs the process. Return to the main flow.

  Next, the bonus operation check process performed under the control of the main CPU 31 will be described with reference to the flowchart of FIG. The bonus operation check process is a process for performing a check for operating a bonus game or the like based on the determined display combination type or the like.

  First, the main CPU 31 determines whether or not the display combination is “BB” (step S121). That is, the main CPU 31 determines whether or not “red 7-red 7-red 7” symbols are aligned along the active line. When determining that the display combination is not “BB”, the main CPU 31 proceeds to the process of step S125.

  When it is determined in step S121 that the display combination is “BB”, the main CPU 31 performs a bonus operating process based on the bonus operating table (see FIG. 14) (step S122). Specifically, the main CPU 31 sets “345” in the bonus end number counter based on the bonus operating time table, and turns on the BB operating flag in the gaming state flag storage area (see FIG. 17C). To do.

    Next, the main CPU 31 turns off the RT game state flag and clears the RT game number counter (step S123). Thereafter, the main CPU 31 sets a bonus start command in a communication data storage area provided in the RAM 33 (step S124), and sets a bonus start command. Thereafter, the main CPU 31 shifts the processing to a main flow (see FIG. 24). The bonus start command includes information indicating that the bonus game has started.

  When determining in step S121 that the display combination is not “BB”, the main CPU 31 determines whether or not the display combination is “replay” (step S125). That is, the main CPU 31 determines whether or not “Replay-Replay-Replay” symbols are aligned on the active line. When determining that the display combination is “replay”, the main CPU 31 shifts the processing to step S127. On the other hand, when determining that the display combination is “replay”, the main CPU 31 copies the value of the insertion number counter to the automatic insertion counter (step S126), and shifts the processing to the main flow. As a result, the same number of medals as the inserted number are awarded and automatically inserted.

  On the other hand, when it is determined in the process of step S125 that the display combination is not “replay”, the main CPU 31 determines whether or not the display combination is “watermelon” (step S127). That is, the main CPU 31 determines whether or not “watermelon-watermelon-watermelon” symbols are aligned on the active line.

  When determining that the display combination is not “watermelon”, the main CPU 31 shifts the processing to the main flow. On the other hand, when determining that the display combination is “watermelon”, the main CPU 31 turns on the RT game state flag and sets “5” in the RT game number counter (step S128). Thereafter, the main CPU 31 ends the bonus operation check process and returns the process to the main flow (see FIG. 18).

  Next, an interrupt process performed under the control of the main CPU 31 will be described with reference to a flowchart shown in FIG. The interrupt process under the control of the main CPU 31 is a process that occurs every predetermined period (for example, 1.1173 milliseconds).

  First, the main CPU 31 saves the register (step S131). Next, the main CPU 31 performs an input port check process (step S132). Specifically, the main CPU 31 checks input of signals from each switch and the like.

  Next, the main CPU 31 performs an input state command setting process (step S133). The input state command is a command for notifying the sub control circuit 72 of the input state of the start lever 6 and the stop buttons 7L, 7C, and 7R. That is, the main CPU 31 checks the input of the start lever 6 and the stop buttons 7L, 7C, and 7R, and sets the input state command in the communication data storage area of the control RAM 33.

  Next, the main CPU 31 performs communication data transmission processing (step S134). Specifically, the main CPU 31 transmits various commands set in the communication data storage area in the control RAM 66 to the sub-control circuit 72.

  The sub control circuit 72 can specify that the stop button 7L, 7C, 7R has been pressed and its type based on the command transmitted in step S134. Therefore, the sub control circuit 72 can stop the rotation of the corresponding sub reels 23L, 23C, 23R based on the transmitted command. That is, in this example, the rotation of the sub reels 23L, 23C, 23R managed by the sub control circuit 72 can be stopped based on the timing when the stop buttons 7L, 7C, 7R are pressed.

  Next, the main CPU 31 performs a reel control process (step S135). Specifically, if the start of rotation of the main reels 3L, 3C, 3R is requested, the rotation of the main reels 3L, 3C, 3R is started, and thereafter, rotation at a constant speed is performed. If the stop control position is determined, the main reel symbol counter of the corresponding main reels 3L, 3C, 3R is updated to the same value as the stop control position, and the rotation is decelerated. And stop.

  Next, the main CPU 31 performs a lamp / 7 SEG drive process (step S136). Specifically, the main CPU 31 performs processing such as displaying the number of payouts on the payout display unit 18a and displaying the number of credits on the credit display unit 18b. Next, the main CPU 31 performs a timer management process (step S137). In this process, various timers are updated. The main CPU 31 then restores the register (step S138) and ends the interrupt process.

<Description of operation of sub-control circuit>
Next, the operation of the sub control circuit 72 will be described with reference to the flowcharts shown in FIGS.

  First, the main flowchart performed by the sub CPU 81 will be described with reference to the flowchart shown in FIG.

  When the gaming machine 1 is powered on, the sub CPU 81 performs an initialization process (step S201). In the initialization process, error checking of the SDRAM 83, initialization of the task system, and the like are performed. The sub control circuit 72 employs a multi-thread multi-task operating system as an OS (operating system) for executing processing. That is, a certain task group and another task group execute processing while preemption (preemption) of the execution right.

  Next, the sub CPU 81 activates a lamp control task (step S202). In the lamp control task, the sub CPU 81 performs lamp related data initialization processing, lamp data analysis processing, lamp lighting control processing, and the like. Next, the sub CPU 81 activates a sound control task (step S203). In the sound control task, the sub CPU 81 performs initialization processing of sound related data, analysis processing of sound data, sound output control processing, and the like.

Next, the sub CPU 81 activates the effect reel control task (step S204). In the effect reel control task, the sub CPU 81 performs an initialization process of related data of the sub reels 23L, 23C, 23R and the 4th reel 110, an analysis process of the sub reel data and the 4th reel data, a sub reel control process, a 4th reel control process, and the like.
These tasks are included in the task group for timer interrupt synchronization, and are sequentially executed according to the priority order.

  Next, the sub CPU 81 activates the main board communication task (see FIG. 35) (step S205). This task executes a corresponding process in response to receiving a command transmitted from the main control circuit 71.

  Next, the main board communication task will be described with reference to the flowchart shown in FIG.

  First, the sub CPU 81 initializes a transmission message queue that receives a command transmitted from the main control circuit 71 (step S211). Next, the sub CPU 81 performs reception check of the command transmitted from the main control circuit 71 (step S212), and determines whether or not a command different from the previous one has been received (step S213).

  If it is determined in step S213 that a command different from the previous command has not been received, the sub CPU 81 proceeds to the process of step S212. On the other hand, when determining that a command different from the previous command has been received, the sub CPU 81 creates game information from the command, and stores the created game information in a game data storage area provided in the SDRAM 83 (step S214).

  The sub CPU 81 creates game information from the parameters of the received command. For example, when the command is a reel stop command, whether the main reels 3L, 3C, 3R are in the first stop, the second stop, or the third stop, the stop control position is “0” to “20”. The game information indicating the position and the number of sliding pieces is created.

  Next, the sub CPU 81 performs a received command analysis process (see FIG. 36) described later (step S215), and returns the process to step S212 again. The received command analysis process is a process for analyzing the received command.

  Next, received command analysis processing will be described with reference to the flowchart shown in FIG.

  First, the sub CPU 81 determines whether or not a start command has been received (step S221). When determining that the start command has not been received, the sub CPU 81 proceeds to the process of step S228. On the other hand, when determining that the start command has been received, the sub CPU 81 determines whether or not the BB gaming state is set (step S222).

  When it is determined in step S222 that the game state is not the BB game state, the sub CPU 81 proceeds to the process of step S225. On the other hand, when it is determined that the game state is the BB game state, the sub CPU 81 sets BB operating effect data (step S223). Subsequently, the sub CPU 81 selects and sets the sub stop table group 9 from the sub reel stop table group determination table (see FIG. 20) (step S224), and proceeds to the processing of step S229.

  When it is determined in step S222 that the BB gaming state is not set, the sub CPU 81 determines whether or not the special sub reel is used (step S225). That is, in step S225, it is determined whether or not the state is changed to the special mode or the normal mode in the sub reel design changing process (see FIG. 37) described later. Yes. In other words, when the special sub reel use counter is “1” or more, the special sub reel can be used. When using the special sub reel, the special sub reel stop mode determination table is referred to (see FIG. 23), the stop mode is determined based on the game information (step S226), and the process proceeds to step S229. The stop mode determined here is performed by displaying the second sub reel band in the display windows 24L, 24C, 24R.

  In the case of the special mode, the sub reels 23L, 23C, etc. are arranged so that the symbol positions “1”, “7”, “13”, “19” of the second sub reel band are aligned with the center effect line 28c of the display windows 24L, 24C, 24R. 23R is stopped. The symbol position to be stopped at this time is determined based on a special sub-reel stop mode determination table (see FIG. 23).

  When it is determined in step S225 that the special sub reel is not used, the sub CPU 81 refers to the effect lottery table (see FIG. 22) and determines the effect data (effect number) based on the game information (step S227). . At this time, the special sub reel use counter is “0”. Then, the sub CPU 81 sets the determined effect data. As a result, an effect corresponding to the effect number is performed with reference to the effect data table (see FIG. 21). Subsequently, the sub CPU 81 refers to the sub reel stop table group determination table (see FIG. 20), and determines a sub stop table group based on the game information (step S228). Then, the sub CPU 81 sets the determined sub stop table group.

  When the sub stop table group 9 is set in the process of step S224, when the stop mode is determined in the process of step S226, and when the sub stop table group is determined and set in the process of step S228, the sub reel rotation start process is performed. (Step S229), the process proceeds to step S238. By the sub reel rotation start process, the rotation of the sub reels 23L, 23C, and 23R is started.

  When determining in step S221 that the start command has not been received, the sub CPU 81 determines whether or not a reel stop command has been received (step S230). When determining that the reel stop command has not been received, the sub CPU 81 proceeds to the process of step S232.

  On the other hand, when determining that the reel stop command has been received, the sub CPU 81 performs a sub reel stop control process (step S231), and proceeds to the process of step S238. In the sub reel stop control process, the sub reels 23L, 23C, and 23R are stopped based on the sliding piece number determination data determined by referring to the stop table, the stop operation detected for the main reels 3L, 3C, and 3R, and the like. Is done.

  When determining in step S230 that the reel stop command has not been received, the sub CPU 81 determines whether or not a display combination command has been received (step S232). When determining that the display combination command has not been received, the sub CPU 81 proceeds to the process of step S234. On the other hand, when determining that the display combination command has been received, the sub CPU 81 performs a sub reel design changing process (see FIG. 37) described later (step S233), and proceeds to the process of step S238. In the sub reel design changing process, the normal mode and the special mode are changed based on the determined display combination.

  When it is determined in step S232 that the display combination command has not been received, the sub CPU 81 determines whether or not a bonus start command has been received (step S234). When determining that the bonus start command has not been received, the sub CPU 81 proceeds to the process of step S236. On the other hand, when determining that the bonus start command has been received, the sub CPU 81 sets BB start effect data (step S235), and proceeds to the processing of step S238.

  When determining in step S234 that the bonus start command has not been received, the sub CPU 81 determines whether or not a bonus end command has been received (step S236). When determining that the bonus end command has not been received, the sub CPU 81 proceeds to the process of step S238. On the other hand, when determining that the bonus end command has been received, the sub CPU 81 sets BB end time effect data (step S237), and proceeds to the processing of step S238.

  Next, the sub CPU 81 requests registration of each set effect data (step S238), and returns the process to the main board communication task (see FIG. 35).

  The sub CPU 81 stops the rotation of the plurality of sub reels based on the internal winning combination determined by the internal winning combination determining means and the detection of the stop operation performed by the stop operation detecting means. Based on the stop mode determined by the stop mode determination table (see FIG. 23), the symbol combination of the second sub reel band is displayed on the sub display windows 24L, 24C, 24R. For this reason, the player does not become monotonous during the replay time operation and tries to predict an internal winning combination, so that the interest of the game can be enhanced.

  Next, with reference to the flowchart shown in FIG. 37, the sub reel symbol changing process performed under the control of the sub CPU 82 will be described.

  First, the sub CPU 82 determines whether or not a special sub reel is used (step S251). In this example, the special sub reel is used when the replay time is in operation (the RT gaming state flag is on).

  When determining that the special sub reel is not used, the sub CPU 82 determines whether or not the display combination is “watermelon” (step S252). When it is determined that the display combination is not “watermelon”, the sub CPU 82 ends the sub reel symbol changing process and returns the process to the received command analyzing process.

  On the other hand, in the process of step S252, when the sub CPU 82 determines that the display combination is “watermelon”, the sub CPU 82 performs a special mode change process (step S253). At this time, the first sub reel band of the sub reels 23L, 23C, and 23R is changed to the “special mode” in which the second sub reel band is changed. And since the symbols of the sub reels 23L, 23C, and 23R are changed, the player feels interested in the production by the special mode.

  Then, the sub CPU 82 sets “5” in the special sub reel use counter (step S254), ends the sub reel symbol change process, and returns the process to the received command analysis process. Here, the value “5” set in the special sub-reel use counter is a value that matches the value “5” of the RT game number counter set in the bonus operation check process (see FIG. 32).

  The special sub reel use counter is a means for counting the number of times the special sub reel can be used, and is updated and stored in the SDRAM 83. When the special sub reel usage counter reaches 0, the special sub reel cannot be used. That is, the special mode returns to the normal mode.

  In the process of step S251, when the sub CPU 82 determines that the special sub reel is being used, the sub CPU 82 determines whether or not the display combination is “BB” (step S255). When it is determined that the display combination is not “BB”, the sub CPU 82 subtracts “1” from the special sub reel usage counter (step S256), and determines whether the special sub reel usage counter is “0” (step S256). Step S257).

  In the process of step S257, when the sub CPU 82 determines that the special sub reel use counter is not “0”, the sub reel design change process is terminated, and the process returns to the received command analysis process.

  When it is determined that the display combination is “BB” in the process of step S255, or when it is determined that the special sub reel use counter is “0” in the process of step S257, the sub CPU 82 performs the normal mode change process. This is performed (step S258). At this time, the second sub reel band of the sub reels 23L, 23C, 23R is changed to the “normal mode” in which the second sub reel band is changed to the first sub reel band. Thereafter, the sub CPU 82 ends the sub reel symbol change process and returns the process to the received command analysis process.

  Next, with reference to FIGS. 38 to 44, specific contents of the effects by the sub reels 23L, 23C, 23R and the 4th reel 110 will be described.

  FIG. 38 is an explanatory diagram showing a state of the main reel, the sub reel, and the 4th reel when all the main reels are stopped.

  As shown in FIG. 38, the rotation of the main reels 3L, 3C, 3R and the sub reels 23L, 23C, 23R is stopped by pressing the stop buttons 7L, 7C, 7R. In this example, the symbol “watermelon” is displayed along the effective line 8a as a display combination in the main display windows 4L, 4C, 4R. Then, the symbol “watermelon” is displayed along the effective line 28a as a display combination in the sub display windows 24L, 24C, 24R. At this time, the 4th reel 110 is driven and controlled, and the symbol “CHANCE” is displayed in the 4th display window 112. As a result, the player is notified that the current game is in the “CHANCE” state. In this example, the symbol positions of the displayed sub reels 23L, 23C, and 23R are “3”, “7”, and “11” with respect to the center effective line 28c.

FIG. 39 is an explanatory diagram showing a state of the main reel, the sub reel, and the 4th reel when the normal mode is changed to the special mode.
When "Watermelon" wins, RT is in operation and a special sub reel is used. That is, the roller is driven to rotate so that the second sub reel bands of the sub reels 23L, 23C, and 23R are displayed in the sub display windows 24L, 24C, and 24R.

FIG. 40 is an explanatory diagram showing a state of the main reel, the sub reel, and the 4th reel after being changed to the special mode.
At this time, the symbols on the back side of the sub reels 23L, 23C, 23R are displayed in the sub display windows 24L, 24C, 24R.

FIG. 41 is an explanatory diagram showing a state of the main reel, the sub reel, and the 4th reel when the stop mode is “blank”.
At this time, the symbol “blank” is displayed on the sub display windows 24L, 24C, and 24R, and the symbol “blank” is also displayed on the 4th reel 110. In this case, the symbol positions at which the sub reels 23L, 23C, 23R stop are “4”, “10”, or “19”. As shown in the special sub-reel stop mode determination table (see FIG. 23), when “blank” is displayed, it can be said that the expectation degree that BB is determined as an internal winning combination is the lowest.

FIG. 42 is an explanatory diagram showing the states of the main reel, the sub reel, and the 4th reel when the stop mode is “?”.
At this time, the symbol “?” Is displayed on the sub display windows 24L, 24C, 24R, and the symbol “?” Is also displayed on the 4th reel 110. In this case, the symbol position at which the sub reels 23L, 23C, and 23R stop is “7” or “19”.

FIG. 43 is an explanatory diagram showing the states of the main reel, the sub reel, and the 4th reel when the stop mode is “CHANCE”.
At this time, the symbol “CHANCE” is displayed on the sub display windows 24L, 24C, and 24R, and the symbol “CHANCE” is also displayed on the 4th reel 110. In this case, the symbol position at which the sub reels 23L, 23C, and 23R stop is “13”.

FIG. 44 is an explanatory diagram showing a state of the main reel, the sub reel, and the 4th reel when the stop mode is “WIN”.
At this time, the symbol “WIN” is displayed on the sub display windows 24L, 24C, and 24R, and the symbol “WIN” is also displayed on the 4th reel 110. In this case, the symbol position at which the sub reels 23L, 23C, and 23R stop is “1”. When the carryover combination storage area is zero, “WIN” is not displayed (see the special sub-reel stop mode determination table (see FIG. 23)). Therefore, when the player notices that “WIN” is displayed, the player can know that the BB carryover state is established. For this reason, the player tries to look for the bonus symbol “red 7-red 7-red 7” in the next game or later to align the display combination.

The configuration and operation of the gaming machine 1 according to one embodiment of the present invention have been described above based on the attached drawings.
According to the gaming machine 1 according to the present embodiment, when a combination of symbols “watermelon-watermelon-watermelon” is displayed along the active lines of the main display windows 4L, 4C, 4R, a predetermined internal winning combination ( (Watermelon) When “Watermelon” wins, a predetermined number of replay times (in this example, 5 times) are activated. During this replay time, special sub reels are used to produce effects. However, the special sub reel is used until the operation of the replay time is completed or until “BB” is established.
Thereby, during the replay time operation, it is possible to change the information obtained from the plurality of main reels 3L, 3C, 3R and the plurality of sub reels 23L, 23C, 23R, thereby improving the interest of the game. Further, when the stop mode is “WIN”, the player's expectation that the bonus is carried over is increased. Increasing this expectation makes it possible to provide an amusing gaming machine.

  In addition, since there is a high possibility that a predetermined internal winning combination (watermelon) is won with overlapping bonuses, there is a high expectation that the bonus will also be won during the replay time. Then, by increasing the player's expectation, it is possible to provide a highly interesting gaming machine.

  In addition, during the replay time, the replay winning probability increases. The replay is set to have a higher priority to be displayed than the bonus. For this reason, in the production using the special sub-reel, the possibility that a bonus is first established on the main reel is reduced, so that the player can enjoy the production using the special sub-reel. .

  Further, according to the gaming machine 1 according to the present embodiment, when the combination of symbols “watermelon-watermelon-watermelon” is displayed along the active lines of the main display windows 4L, 4C, 4R, the sub display window A combination of symbols “watermelon-watermelon-watermelon” is always displayed along the effect lines 24L, 24C, 24R. Thereby, it can be notified by a plurality of sub reels 23L, 23C, 23R that "watermelon" has won. As a result, the player can be surely recognized that “watermelon” has won.

  Further, according to the gaming machine 1 according to the present embodiment, the 4th reel 110 notifies that “BB” is included in the internal winning combination. Thus, the stop operation can be performed so that “BB” wins in the current game. As a result, it is possible to prevent the game from becoming monotonous and to enhance the interest of the game.

  In the gaming machine 1 according to the above-described embodiment, when “watermelon” wins, the combination of symbols “watermelon-watermelon-watermelon” is always set along the effect lines of the sub display windows 24L, 24C, 24R. Configured to be displayed. In other words, the same data is used in the stop table group for the main reel and the stop table group for the sub reel. However, as a gaming machine according to the present invention, even when “watermelon” wins, a combination of symbols “watermelon-watermelon-watermelon” is displayed along the production lines of the sub display windows 24L, 24C, 24R. It is good also as a structure which is not performed.

  Further, the symbols arranged on the first and second sub reel bands are not limited to the above-described embodiment. In addition to the decorative characters, a symbol such as a character may be arranged to give the player interest.

  Further, in the gaming machine 1 according to the above-described embodiment, the sub reels 23L, 23C, and 23R have been described as the mechanisms including the first and second sub reel bands. However, for example, the sub reels may be displayed on the liquid crystal display device. . In this case, the symbols of the sub reels can be changed in two or more stop modes to make the player interested.

In the gaming machine 1 according to the above-described embodiment, only “BB” is applied as the special internal winning combination for starting the BB, but the special internal winning combination according to the present invention is not limited to “BB”. In this example, “watermelon” is applied as an internal winning combination for operating the replay time. However, the predetermined internal winning combination according to the present invention is not limited to “watermelon”. Further, two or more kinds of special internal winning combinations and internal winning combinations that activate the replay time may be set.
