Description

  The present invention relates to a gaming machine.

  Conventionally, it has a plurality of reels on which a plurality of symbols are drawn on the peripheral surface, and a symbol display window that is provided in correspondence with each reel and displays a part of the symbols drawn on the peripheral surface of each reel. , Based on the player's input of game value such as medals and the operation on the start lever (referred to as “start operation”), all reels are rotated, and on the basis of the player's operation on the stop button (referred to as “stop operation”). A gaming machine (so-called “pachi-slot”) is known in which symbols are stopped and displayed on a symbol display window by stopping each reel. Such a gaming machine gives a privilege (for example, a medal) to a player when a predetermined symbol combination is stopped and displayed in the symbol display window.

  The current mainstream gaming machine draws one or more roles from among a plurality of roles in advance within the gaming machine based on the player's start operation (referred to as “internal lottery”) and wins the winning role (“internal The reel stop control is performed based on the “winning combination” and the player's stop operation, and the combination of symbols related to the internal winning combination is stopped and displayed on the symbol display window. In addition, as a type of a combination, it is advantageous for a player to give a game value to a player, a re-playing role that allows replay without any gaming value (referred to as “replay”), and a player. BB combination (referred to as “BB”) that activates a BB operating state that continuously generates a certain gaming state (referred to as “RB gaming state”) until a predetermined condition is satisfied.

  In addition, in normal gaming machines, there are a plurality of small combinations, and even if these small combinations are determined as internal winning combinations, the symbols related to the internal winning combination are stopped. For example, there are a combination that is difficult to establish unless a stop operation is performed at an appropriate timing, and a combination that is not established unless a stop operation is performed on the reels in a predetermined order. In this way, a period for notifying the player of the information for establishing the internal winning combination so that the determined winning combination cannot be established, so that the so-called oversight does not occur (“assist time (AT operation There is known a gaming machine that activates a state)) after the end of the BB operation state.

In addition, there is a player who is in a disadvantage because the number of inserted medals increases with respect to the number of paid out medals due to the BB not being determined as an internal winning combination for a long period of time. Under such circumstances, there is known a gaming machine that rescues a player by operating an AT operation state when a value obtained by subtracting the total paid-out number of medals from the total number of inserted medals of the player becomes a predetermined value. (For example, Patent Document 1).
JP 2003-290441 A

  However, in the above-mentioned gaming machine, when the value obtained by subtracting the total paid-out number of medals from the total inserted number of medals becomes a predetermined value, the player in an unfavorable situation is relieved by operating the AT operation state. On the other hand, when BB is determined as an internal winning combination at intervals shorter than usual, the value obtained by subtracting the total number of medals inserted from the total number of medals paid out increases, and the player's joyfulness There was a risk of scolding.

  The present invention has been made in view of the above-mentioned problems. By preventing the difference between the total number of inserted medals and the total number of paid-out medals from increasing, the player can be rescued and the player's happiness The purpose is to provide a gaming machine that does not mind.

  The sub-control circuit 70 performs various processes such as determination and execution of effect contents based on various commands output from the main control circuit 60 such as a start command described later. The sub control circuit 70 does not input commands, information, or the like to the main control circuit 60, and communication is performed in one direction from the main control circuit 60 to the sub control circuit 70.

  The main actuators whose operation is controlled by a control signal from the sub control circuit 70 include the liquid crystal display device 5, the speakers 21L and 21R, and the LED 101. The sub control circuit 70 determines and displays an image displayed on the liquid crystal display device 5 based on the determined content of the effect, determines and outputs the lighting pattern of the LED 101, and the effect sound and sound effect output from the speakers 21L and 21R. Control and output control.

  Details of the configuration of the sub control circuit 70 in the present embodiment will be described later.

  In the gaming machine 1, when a signal for starting a unit game is output from the start switch 6S by a player's operation on the start lever 6 on condition that a medal is inserted, a control signal is output to the motor drive circuit 39, and stepping is performed. The rotation of the reels 3L, 3C, 3R is started by drive control of the motors 49L, 49C, 49R (for example, excitation to each phase). At this time, the number of pulses output to the stepping motors 49L, 49C, 49R is counted, and the counted value is set in a predetermined area of the RAM 33 as a pulse counter. In the gaming machine 1, when the “16” pulse is output, the reels 3L, 3C, and 3R move by one symbol. The number of symbols moved is counted, and the counted value is set in a predetermined area of the RAM 33 as a symbol counter. That is, every time the pulse counter counts “16”, the symbol counter is updated by “1”.

  A reel index is obtained from the reels 3L, 3C, and 3R for each rotation and is output to the main CPU 31 via the reel position detection circuit 50. With the output of the reel index, the pulse counter and the symbol counter set in the RAM 33 are cleared to “0”. In this way, the symbol position within one rotation range is specified for each reel 3L, 3C, 3R. The distance that each symbol moves by one symbol by the rotation of the reel is called one frame. That is, moving the symbol by one frame corresponds to updating the symbol counter by “1”.

  Here, in the ROM 32, a symbol arrangement table (see FIG. 2) is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R with the symbols drawn on the outer peripheral surface of the reel. ing. In this symbol arrangement table, the code numbers from “00” to “20”, which are sequentially given for each fixed rotation pitch of each of the reels 3L, 3C, and 3R, with the position where the reel index is output as a reference, A symbol code for identifying the type of symbol provided corresponding to each code number is associated.

  When a start signal is output from the start switch 6S, a random number value is extracted by the random number generator 36 and the sampling circuit 37. In the gaming machine 1, when the random value is extracted, it is stored in the random value storage area of the RAM 33. Then, an internal winning combination is determined based on the random value stored in the random value storage area.

  After the reels 3L, 3C, and 3R have reached constant speed rotation, when a stop signal is output from the stop switches 7LS, 7CS, and 7RS by a stop operation, based on the output stop signal and the determined internal winning combination, A control signal for stopping and controlling the reels 3L, 3C, 3R is output to the motor drive circuit 39. The motor drive circuit 39 drives and controls the stepping motors 49L, 49C, 49R, and stops the rotation of the reels 3L, 3C, 3R.

  When the rotation of all the reels 3L, 3C, 3R is stopped, the display combination search process is performed based on the combination of symbols displayed on the effective line. The search for the display combination is performed based on the symbol combination table (see FIG. 8) stored in the ROM 32. In this symbol combination table, a symbol combination related to a display combination and a corresponding payout are set.

  When it is determined by the display combination search that a combination of symbols related to winning is displayed, a control signal is output to the hopper driving circuit 41 and the hopper 40 is driven to pay out medals. At this time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 40, and when the count value reaches a designated number, the payout completion signal circuit 51 outputs a signal indicating completion of medal payout. The Thereby, a control signal is output to the hopper drive circuit 41, and the drive of the hopper 40 is stopped.

  When the credit mode is switched by the C / P switch 14S, if it is determined that the winning symbol combination is displayed, the payout amount corresponding to the winning symbol combination is stored in the credit of the RAM 33. Add to the number counter. Further, a control signal is output to the display unit driving circuit 48 and the value of the credit number counter is displayed on the credit display unit 19. Here, there is a case where a medal payout or a credit performed when a symbol combination related to winning is displayed is simply referred to as “payout”.

  Next, the circuit configuration of the sub control circuit 70 will be described with reference to FIG. FIG. 4 is a diagram showing a circuit configuration of the sub control circuit of the gaming machine 1.

The LED 101 functions not only as a decorative lamp (see FIG. 1) provided on the front surface of the gaming machine 1, but also as a back lamp provided inside the reels 3L, 3C, 3R.

  Based on the program stored in the control ROM 72, the sub CPU 71 performs display control of the liquid crystal display device 5, output control of the speakers 21L and 21R, lighting control of the LED 101, and the like. Specifically, the sub CPU 71 receives a gaming state and various commands from the main control circuit 60 and stores various information in the SDRAM 73. The sub CPU 71 executes the program while referring to the game state information, the internal winning combination information and the like stored in the SDRAM 73, thereby causing the rendering device such as the liquid crystal display device 5, the speakers 21L and 21R, and the LED 101 to perform. Select content. Further, the sub CPU 71 controls the liquid crystal display device 5 via the rendering processor 74 based on the selected effect content, and controls the sound output from the speakers 21L and 21R and the lighting of the LED 101.

  In addition, the sub CPU 71 executes a random number acquisition program stored in the control ROM 72, thereby acquiring a random number value used when selecting the contents of effects and the like. However, similarly to the main control circuit 60, a random number generator and a sampling circuit may be provided in the sub control circuit 70 to perform the processing.

  In the present embodiment, the sub CPU 71 calculates a BB winning rate α, which will be described later, by executing a program, and performs an AT operation lottery, which will be described later, based on the calculated BB winning rate α and the AT operating lottery table. When the result of the operation lottery is winning, the AT operation state is activated. Further, the sub CPU 71 performs AT number lottery described later based on the calculated BB winning rate α and the AT number lottery table, and determines the AT number described later. Further, the sub CPU 71 performs an AT game number lottery described later on the basis of the calculated BB winning rate α and the AT game number lottery table, and determines an AT game number described later. Furthermore, the sub CPU 71 causes the liquid crystal display device 5 to display an auxiliary image for establishing an internal winning combination in the AT operation state. The sub CPU 71 of the present embodiment constitutes a winning probability calculation means, an operation lottery means, an auxiliary effect period operation means, an operation frequency lottery means, and a game number lottery means of the present invention. Moreover, the liquid crystal display device 5 of this embodiment comprises the production | presentation means of this invention.

  The control ROM 72 has a program storage area for storing programs executed by the sub CPU 71 and a data storage area for storing various tables. The program storage area includes an operating system, a device driver, an inter-board communication task for controlling communication with the main control circuit 60, an LED control task for controlling light output by the LED 101, and sound output by the speakers 21L and 21R. The voice control task for controlling the effect, the effect registration task for determining the content of the effect, the drawing control task for controlling the display of the video by the liquid crystal display device 5 based on the determined content of the effect, and the like are stored. On the other hand, the data storage area is a table storage area for storing an effect selection table, an AT operation lottery table, an AT number lottery table, an AT game number lottery table, a drawing control data storage area for storing animation data such as character object data, It has an audio control data storage area for storing sound data such as BGM and sound effects, an LED control data storage area for storing lighting patterns, and the like. The control ROM 72 of the present embodiment constitutes an operation lottery table storage unit, an operation number lottery table storage unit, and a game number lottery table storage unit of the present invention.

  The SDRAM 73 is used as work temporary storage means when the sub CPU 71 executes each program. For example, the SDRAM 73 stores information such as commands transmitted from the main control circuit 60, in-game information, production content information, gaming state information, internal winning combination information, carryover combination information, display combination information, various counters, various flags, and the like. To do.

  The rendering processor 74 performs a process for displaying an image on the liquid crystal display device 5 based on an image display command or the like received from the sub CPU 71. Data necessary for processing performed by the rendering processor 74 is expanded in the drawing SDRAM 75 at the time of activation. The rendering processor 74 generates image data by superimposing the image data developed on the drawing SDRAM 75 in order from the background image located at the rear to the image located at the front, and supplies the image data to the liquid crystal display device 5 via the driver 77. To do. As a result, an image corresponding to the effect content determined by the sub CPU 71 is displayed on the liquid crystal display device 5.

  The drawing SDRAM 75 has two frame buffers 76 of a writing image data area and a display image data area. The writing image data area stores image data generated by the rendering processor 74 and displays a display image. The image data area stores image data to be displayed on the liquid crystal display device 5. The rendering processor 74 causes the liquid crystal display device 5 to sequentially display image data by alternately switching these frame buffers (that is, the banks are switched).

  The A / D converter 78 converts the sound data in the digital format selected by the sub CPU 71 based on the contents of the effect into sound data in the analog format, and transmits it to the amplifier 79. The amplifier 79 amplifies the analog-format sound data received from the A / D converter 78 based on the volume adjusted by a volume adjustment knob (not shown) provided in the gaming machine 1, and the speakers 21L and 21R. Send to. As a result, a sound corresponding to the effect content determined by the sub CPU 71 is output from the speakers 21L and 21R.

  Next, an internal lottery table determination table used in an internal lottery process (see FIG. 19) described later will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of an internal lottery table determination table of the gaming machine 1 in the present embodiment.

  The internal lottery table determination table defines an internal lottery table used for determining an internal winning combination in the internal lottery process for each gaming state and set value, and the number of lotteries. Specifically, based on the internal lottery table determination table, when the gaming state is the general gaming state and the set value is “1”, the internal lottery table for the general gaming state (setting 1) is used. “9” is determined as the number of lotteries, and when the set value is “6”, it is determined that the internal lottery table for the general gaming state (setting 6) is used and lottery is performed. “9” is determined as the number of times. When the gaming state is the MB gaming state and the set value is “1”, it is determined that the internal lottery table for the general gaming state (setting 1) is used and the number of lotteries is “5”. ”Is determined, and when the set value is“ 6 ”, it is determined that the internal lottery table for the general gaming state (setting 6) is used, and“ 5 ”is determined as the number of lotteries. Further, when the gaming state is the RB gaming state, it is determined that the RB gaming state internal lottery table is used and “5” is determined as the number of lotteries. However, when the gaming state is the general gaming state, the number of lotteries is updated to “6” in the internal lottery process when a BB1 carryover state, a BB2 carryover state, or an MB carryover state described later. The set value will be described later.

  Next, an internal lottery table used for determining an internal winning combination in an internal lottery process (see FIG. 19) described later will be described with reference to FIGS. FIG. 6A is a diagram illustrating an example of an internal lottery table for the general gaming state (setting 1) of the gaming machine 1 in the present embodiment. FIG. 6 (2) is a diagram showing an example of an internal lottery table for the general gaming state (setting 6) of the gaming machine 1 in the present embodiment. FIG. 6 (3) is a diagram showing an example of an internal lottery table for RB gaming state of the gaming machine 1 in the present embodiment. Note that the internal lottery table for the general gaming state (setting 1) and the internal lottery table for the general gaming state (setting 6) may be collectively referred to as an internal lottery table for the general gaming state.

  The internal lottery table of the internal lottery table for the general gaming state (setting 1), the internal lottery table for the general gaming state (setting 6), and the internal lottery table for the RB gaming state is in which gaming state or any set value. Depending on whether it is.

  In the internal lottery table, a lower limit value and an upper limit value are defined for each winning number. The winning number corresponds to each combination and is a number used when determining an internal winning combination in the internal lottery process. Specifically, in the gaming machine 1, the random number value stored in the RAM 33 is a value within the range from the lower limit value to the upper limit value (sometimes referred to as “winning range”) defined in the internal lottery table. In this case, the winning combination corresponding to the winning number corresponding to the winning range is determined as an internal winning combination. In the internal lottery process, if the random number is a value that is not included in any winning range, it means that the lottery is out of the internal lottery and “0” is determined as the winning number.

  As shown in FIG. 6 (1), in the internal lottery table for the general gaming state (setting 1), the winning numbers “1” to “9” are Cherry 1, Cherry 2, Cherry 3, Bell, Watermelon, Replay, It corresponds to BB1, BB2, and MB. Also, in the internal lottery table for the general gaming state (setting 1), the winning range is such that the probability that BB1 or BB2 is determined as the internal winning combination is “(100 + 100) / 65536 (about 0.31%)”. It is prescribed. On the other hand, as shown in FIG. 6 (2), in the internal lottery table for the general gaming state (setting 6), the probability that BB1 or BB2 is determined as the internal winning combination is “(130 + 130) / 65536 (about 0.40). %) ”Is specified. That is, the higher the set value, the higher the probability that BB1 or BB2 is determined as an internal winning combination, which is more advantageous for the player. Here, the set value is a standard indicating the degree of advantage for the player. In the present embodiment, an internal lottery table corresponding to the set value “1” and an internal lottery table corresponding to the set value “6” are exemplified. Yes, an internal lottery table corresponding to each value is provided in the ROM 32.

  As shown in FIG. 6 (3), the winning range for replay and various bonuses (BB1, BB2, MB) is not defined in the internal lottery table for RB gaming state. In the example of FIG. 6 (3), the internal lottery table for the RB gaming state is defined such that all the small combinations are always determined as internal winning combinations. Further, in the RB gaming state, the number of inserted medals is defined as one, and the payout number of all small roles when the number of inserted medals is one is defined as 15. Therefore, in comparison with the general gaming state in which the internal lottery table for general gaming state is used, in the RB gaming state in which the internal lottery table for RB gaming state is used, many medals are paid out with a small number of unit games. The game state is advantageous for the player.

  Next, an internal winning combination determination table used when determining an internal winning combination in an internal lottery process (see FIG. 19) described later will be described with reference to FIG. FIG. 7 is a diagram showing an example of an internal winning combination determination table of the gaming machine 1 in the present embodiment.

  In the internal winning combination determination table, an internal winning combination corresponding to the winning number is defined. Also, the internal symbol combination determination table defines an internal symbol combination 1 and an internal symbol combination 2, each of which is 1-byte data. The combination of the internal symbol combination 1 and the internal symbol combination 2 determines the internal symbol combination. Can be identified. Specifically, each combination can be identified based on which bit is “1”. Each of the data of the internal winning combination 1 and the internal winning combination 2 is an internal winning combination 1 storage area and an internal winning combination 2 storage area (the internal winning combination 1 storage area and the internal winning combination 2 storage area, which will be described later). And is referred to when the main control circuit 60 determines an internal winning combination. If a plurality of winning combinations are determined as internal winning combinations, “1” is stored in the corresponding bits.

  Specifically, as shown in the internal winning combination determination table, the winning numbers “0” to “9” are lost, cherry 1, cherry 2, cherry 3, bell, watermelon, replay, BB1, BB2, and MB, respectively. Correspond.

  Next, with reference to FIG. 8, the display combination corresponding to the displayed symbol combination and its payout will be described. FIG. 8 is a diagram showing an example of the symbol combination table of the gaming machine 1 in the present embodiment.

  In the symbol combination table, a symbol combination related to privilege provision displayed on the active line, a display combination corresponding to the symbol combination, and a payout number are defined. Each display combination is identified by the display combination 1 and the display combination 2 in the same manner as the internal winning combination 1 and the internal winning combination 2 defined in the internal winning combination determination table.

  In the symbol combination table, cherry 1, cherry 2, cherry 3, bell, watermelon, replay, BB1, BB2, and MB are set as display combinations.

  Cherry 1 is established by displaying “red cherry symbol-ANY-ANY” on the active line. Thereby, when the inserted number is 1, 15 medals are paid out, and when the inserted number is 3, 10 medals are paid out. “ANY” represents that any symbol may be used.

  Cherry 2 is established when “blue cherry symbol-ANY-ANY” is displayed on the active line. Thereby, when the inserted number is 1, 15 medals are paid out, and when the inserted number is 3, 10 medals are paid out.

  Cherry 3 is established by displaying “peach cherry symbol-ANY-ANY” on the active line. Thereby, when the inserted number is 1, 15 medals are paid out, and when the inserted number is 3, 10 medals are paid out.

  Here, cherry 1, cherry 2, and cherry 3 (collectively called cherry 1, cherry 2, and cherry 3) are displayed as red cherry, blue cherry, and peach cherry symbols in the left symbol display area 4L, respectively. In addition, as described above, the red cherry design, the blue cherry design, and the peach cherry design are arranged on the left reel 3L at intervals of 6 designs. Even when any cherry is determined, if it is not possible to determine which cherry is determined as the internal winning combination, the cherry determined as the internal winning combination cannot be established. Therefore, when a cherry is determined as an internal winning combination, information indicating which of the cherries 1, 2 and 3 is determined as an internal winning combination is meaningful information for the player.

  The bell is established when “bell symbol-bell symbol-bell symbol” is displayed on the active line. As a result, 15 medals are paid out when the inserted number is 1, and 8 medals are paid out when the inserted number is 3. In addition, when the game is in the general gaming state and in the non-AT operation state, and an AT number counter, which will be described later, is 1 or more, the AT operation state is activated when the bell is established.

  The watermelon is established by displaying “watermelon symbol-watermelon symbol-watermelon symbol” on the active line. Thereby, when the inserted number is 1, 15 medals are paid out, and when the inserted number is 3, 3 medals are paid out. Also, in the general gaming state, an AT operation lottery is performed when a watermelon is established.

  Replay is established when “replay symbol-replay symbol-replay symbol” is displayed on the active line. Thereby, the re-game is performed in the next unit game. That is, the same number of medals as the number of coins inserted in the unit game in which replay is established are automatically inserted in the next unit game without being based on the player's insertion operation. Thereby, the player can perform the next unit game without consuming medals. Here, the above-mentioned medal payout and re-game are examples of giving game value. In the present embodiment, when the replay is determined to be an internal winning combination, the reel stop control is activated regardless of the timing of the stop operation, and “replay symbol-replay symbol-replay symbol” is displayed. It will be displayed on the active line.

  BB1 is established when “red 7 symbol-red 7 symbol-red 7 symbol” is displayed on the active line, and then the BB1 operation state is established. When the gaming machine 1 enters the BB1 operating state, the gaming machine 1 continuously operates the RB gaming state until the payout number of medals exceeds 345. Further, the RB gaming state is terminated when the number of unit games performed in the RB gaming state reaches 12 times or when the number of winnings reaches 8 times. However, even before the end condition is satisfied, when the BB1 operation state is ended because the number of medals paid out exceeds 345, the RB gaming state is ended accordingly.

  BB2 is established when “blue 7 symbol-blue 7 symbol-blue 7 symbol” is displayed on the active line, and then the BB2 operation state is established. When the gaming machine 1 enters the BB2 operating state, the gaming machine 1 continuously operates the RB gaming state until the payout number of medals exceeds 345. Similarly to the case of the BB1 operating state, when the BB2 operating state is ended because the number of medals paid out exceeds 345, the RB gaming state is ended accordingly. BB1 and BB2 may be collectively referred to as BB.

  The MB is established by displaying “BAR symbol-BAR symbol-BAR symbol” on the active line, and thereafter, the MB gaming state is set. In the MB gaming state, all the small combinations are determined to be internal winning combinations, and the number of slips to be described later for the left reel 3L is determined to be within “1” frames. Can display a combination of symbols related to a small combination with a large number of payouts on the active line, and can advantageously advance the game.

  In addition, when a combination of symbols other than the combination of symbols related to Cherry 1, Cherry 2, Cherry 3, Bell, Watermelon, Replay, BB1, BB2, or MB is displayed on the effective line, a loss occurs.

  Next, with reference to FIG. 9, a bonus operation time table used when setting conditions for ending the BB1 operation state, the BB2 operation state, the RB game state, and the MB game state will be described. FIG. 9 is a diagram showing an example of the bonus operation time table of the gaming machine 1 in the present embodiment. Further, the BB1 operating state and the BB2 operating state may be collectively referred to as a BB operating state.

  In the bonus operation time table, end conditions relating to the BB1 operation state, the BB2 operation state, the RB gaming state, and the MB gaming state are defined. Specifically, in the bonus operation time table, “345” is defined for the value of the bonus end number counter as the end condition of the BB1 operation state and the BB2 operation state, and the possible number of games is set as the end condition of the RB game state. “12” and “8” are defined for the value of the number of possible winnings, respectively. That is, in the gaming machine 1, the BB1 operation state and the BB2 operation state are terminated when the number of medals paid out exceeds 345, and the RB game state is played 12 times or won 8 times. To finish. Also, the MB gaming state ends when the number of medals paid out exceeds 150.

  Next, the internal winning combination storing area and the carryover combination storing area for storing the internal winning combination information will be described with reference to FIGS. FIG. 10 (1) is a diagram showing an example of the internal winning combination 1 storage area of the gaming machine 1 in the present embodiment, and FIG. 10 (2) is an internal winning combination 2 of the gaming machine 1 in the present embodiment. It is a figure which shows the example of a storage area. FIG. 10 (3) is a diagram showing an example of the carryover combination storage area of the gaming machine 1 in the present embodiment.

  The internal winning combination 1 storage area and the internal winning combination 2 storage area are 8-bit data areas allocated on the RAM 33, respectively. Each internal winning combination storage area indicates which combination is an internal winning combination by storing data of “0” or “1” in the area of bits “0” to “5”. Specifically, each of the bits “0” to “5” constituting the internal winning combination 1 storage area of FIG. 10A is stored with “1”, so that cherry 1, cherry 2, cherry 3, Bell, watermelon and replay indicate internal winning combination. In addition, by storing “1” in each of the bits “0” to “2” constituting the internal winning combination 2 storage area of FIG. 10 (2), BB 1, BB 2, and MB are internal winning combinations, respectively. Indicates that there is.

  In the present embodiment, bits “6” and “7” in the internal winning combination 1 storage area and bits “3” to “7” in the internal winning combination 2 storage area are not used, but when more combinations are set. Can be used. Further, if there are not enough bits for identifying the internal winning combination even if these unused areas are used, the internal winning combination storing area 4 can be newly allocated on the RAM 33. When a display combination is determined based on the symbol combination table, data indicating the display combination is stored in the display combination storage area on the RAM 33. The display combination storage area is the same as the internal winning combination storage area. It becomes the composition of.

  Next, a carryover combination storage area for storing carryover combination information will be described with reference to FIG. The carryover combination storage area is an 8-bit data area allocated on the RAM 33. In the carryover combination storage area, data “0” or “1” is stored in each of the bits “0” to “2”, thereby indicating whether the BB1 carryover state, the BB2 carryover state, or the MB carryover state, respectively. Show.

  Here, the BB1 carryover state is a period until “red 7 symbol-red 7 symbol-red 7 symbol” is displayed on the active line when BB1 is determined as an internal winning combination in the general gaming state. BB1 is carried over as an internal winning combination. The BB2 carryover state means that when BB2 is determined as an internal winning combination in the general gaming state, BB2 is displayed until “blue 7 symbol-blue 7 symbol-blue 7 symbol” is displayed on the active line. A state that is carried over as an internal winning combination. In addition, the MB carryover state means that when the MB is determined as an internal winning combination in the general gaming state, the MB is internally displayed until “BAR symbol-BAR symbol-BAR symbol” is displayed on the active line. A state that is carried over as a winning role.

  Next, the operating flag storage area will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of the operating flag storage area of the gaming machine 1 in the present embodiment.

  The operating flag storage area is an 8-bit data area allocated on the RAM 33. The operating flag storage area stores data of “0” or “1” in each of the bits “0” to “3”, so that the RB operation, the BB1 operation, the BB2 operation, or the MB operation is performed, respectively. Indicates whether there is. That is, it indicates whether each operating flag is on or off.

  Next, with reference to FIGS. 12 (1) and (2), the general game state effect selection table and the AT operation state effect selection table will be described. In addition, FIG. 12 (1) is a figure which shows the example of the general game state production | presentation selection table of the gaming machine 1 in this embodiment. FIG. 12 (2) is a diagram showing an example of an AT operation state effect selection table of the gaming machine 1 in the present embodiment. The general game state effect selection table, the AT operation state effect selection table, the BB operation state effect selection table (not shown), and the MB game state effect selection table (not shown) are collectively referred to as an effect selection table.

  In the effect selection table, a lottery value corresponding to the effect number is defined for each internal winning combination. The production number corresponds to the production content. The effect selection table is a table used when determining the contents of the effect (effect number) in the effect lottery process (see FIG. 27) described later. The sub CPU 71 determines an effect number based on a random value acquired in advance and a lottery value defined in the effect selection table (this lottery is referred to as “effect content lottery”).

  The lottery value is a value to be subtracted from the random value acquired in advance by the sub CPU 71 in the effect content lottery. Specifically, the sub CPU 71 subtracts the lottery value from the random number value, and when the subtraction result is negative, the sub CPU 71 selects the effect number corresponding to the lottery value, that is, the effect content. For example, in the general game state effect selection table of FIG. 12A, when the internal winning combination is watermelon and the acquired random number value is “61000”, first, the sub CPU 71 starts the effect number from “61000”. The lottery value “60672” corresponding to “0” is subtracted. The subtraction result is “61000-60672 = 328” and is positive (that is, not negative). Next, the sub CPU 71 subtracts the lottery value “512” corresponding to the effect number “1” from the value “328” after the subtraction. The subtraction result is “328−512 = −184”, which is negative. Therefore, the sub CPU 71 selects the production number “1”, that is, “production A” as the production content. Here, when subtracting the lottery value from the random number value, the sub CPU 71 sequentially subtracts the lottery value corresponding to the smaller production number.

  In this embodiment, when effect content lottery is performed, a random number value in the range of “0 to 65535” is acquired in advance, and the effect selection table specifies lotteries specified for one winning combination. The lottery value is defined so that the sum of the values is “65536”. The lottery value corresponds to a ratio with respect to “0 to 65535” that is a range in which random number values are extracted.

  The general game state effect selection table shown in FIG. 12A is a table used in the general game state. In the general game state effect selection table, “normal effect”, “effect A”, “effect B”, “effect C”, and “effect D” are provided as effect contents corresponding to the effect numbers “0” to “7”, respectively. ", Production E", "production F", and "production G" are defined.

  Next, the case where the internal winning combination is any one of Cherry 1 to Cherry 3 in the general gaming state effect selection table will be described. In this case, the general gaming state effect selection table corresponds to any of the effect numbers “1” to “5” when the carry-over state is not the BB1 carry-over state, the BB2 carry-over state, or the MB carry-over state. The lottery value is defined so that the production content is determined with a probability of “1024 × 5/65536 (about 7.8%)”, while the BB1 carryover state, BB2 carryover state, or MB as shown in * 1 In the case of any carryover state of the carryover state, the production content corresponding to any of the production numbers “1” to “5” is determined with a probability of “2048 × 5/65536 (about 15.6%)”. The lottery value is defined as follows. That is, when the internal winning combination is any one of Cherry 1 to Cherry 3, the player performs an effect corresponding to any of the effect numbers “1” to “5” by each effect device. At this time, it can be estimated that there is a high possibility that the BB carryover state or the MB carryover state is in the carryover state.

  The AT operation state effect selection table shown in FIG. 12 (2) is a table used in the AT operation state. In the AT operation state effect selection table, “normal effect”, “cherry 1 notification effect”, “cherry 2 notification effect”, “effect effect” corresponding to the effect numbers “0”, “11” to “15”, respectively, “Cherry 3 notification effect”, “Bell notification effect”, and “Watermelon notification effect” are defined.

  In the AT operation state effect selection table, when the internal winning combination is lost, the effect content “normal effect” corresponding to the effect number “0” is determined with a probability of “65536/65536 (100%)”. The lottery value is defined as follows. Similarly, in the AT operation state effect selection table, when the internal winning combination is Cherry 1, Cherry 2, Cherry 3, Bell or Watermelon, the effect number “11” (Cherry 1 notification effect) and the effect number “12” "Cherry 2 notification effect", effect number "13" (Cherry 3 notification effect), effect number "14" (Bell notification effect) or effect number "15" (watermelon notification effect) respectively "65536/65536 (100% The lottery value is defined so as to be determined by the probability of “)”.

  The effect content “Cherry 1 notification effect” is an effect content that causes the liquid crystal display device 5 to display an auxiliary image that suggests that the red cherry symbol should be stopped in the left symbol display area 4L. The effect content “Cherry 2 notification effect” is an effect content that causes the liquid crystal display device 5 to display an auxiliary image that suggests that the blue cherry symbol should be stopped in the left symbol display area 4L. The “effect” is the effect of causing the liquid crystal display device 5 to display an auxiliary image that suggests that the peach cherry symbol should be stopped in the left symbol display area 4L. The player can establish a cherry determined as an internal winning combination by performing a stop operation by pushing the left reel 3L with reference to these auxiliary images.

  The effect content “bell notification effect” or “watermelon notification effect” is an effect content that causes the liquid crystal display device 5 to display an auxiliary image that suggests that the bell or watermelon is determined to be an internal winning combination. When the bell or the watermelon is determined as the internal winning combination, the player can establish it by performing a stop operation with reference to these auxiliary images.

  In the general game state effect selection table, the lottery value corresponding to the effect numbers “1” to “5” varies depending on whether the BB carryover state or the MB carryover state. Thus, the lottery value corresponding to the normal performance changes. In the example of FIG. 12 (1), the lottery value corresponding to the production number “0” (normal production) is described for a case where neither the BB carryover state nor the MB carryover state is in effect. The program ROM 73 stores a BB operation state effect selection table and an MB game state effect selection table, but the illustration of these effect selection tables is omitted.

  Next, the setting 1 AT operation lottery table and the setting 6 AT operation lottery table will be described with reference to FIGS. FIG. 13 (1) is a diagram showing an example of an AT operation lottery table for setting 1 of the gaming machine 1 in the present embodiment. FIG. 13 (2) is a diagram showing an example of an AT operation lottery table for setting 6 of the gaming machine 1 in the present embodiment. The setting 1 AT operation lottery table and the setting 6 AT operation lottery table are collectively referred to as an AT operation lottery table.

  The AT operation lottery table is a table used when performing an AT operation lottery in a display command receiving process (see FIG. 29) described later. In the AT operation lottery table, lottery values corresponding to winning and non-winning are defined according to the range in which the BB winning rate α is divided. The BB winning rate α is the ratio of the number of BB winning times that BB1 or BB2 is determined as an internal winning combination with respect to the number of games since the power of the gaming machine 1 is turned on.

  The sub CPU 71 determines whether the winning or non-winning is made based on the random value acquired in advance and the lottery value defined in the AT operation lottery table. Note that the method for determining the winning or non-winning based on the random number value and the lottery value defined in the AT operation lottery table is the same as the effect content lottery, and thus the description thereof is omitted. In addition, when performing an AT operation lottery, a random number value in the range of “0 to 255” is acquired in advance, and the lottery value is set to “256” in the AT operation lottery table. Value is specified. In other words, the AT operation lottery table defines the lottery values corresponding to the winning and non-winning ranges for each range in which the BB winning rate α is divided, so that the AT operation is performed for each range in which the BB winning rate α is divided. It defines the winning probability in lottery.

  The setting 1 AT operation lottery table shown in FIG. 13A is a table used when the set value is “1”. In the AT operation lottery table for setting 1, when “α <1/400 (0.25%)”, the lottery value is determined so as to win with a probability of “88/256 (about 34.4%)”. It is prescribed. In addition, when “1/400 (0.25%) ≦ α <1/300 (about 0.33%)”, the winning probability is “76/256 (about 29.7%)”. A lottery value is defined, and when “1/300 ≦ α”, the lottery value is defined to win with a probability of “64/256 (25.0%)”. That is, when the set value is “1”, the actual BB winning rate α is compared with the above “about 0.31%” which is the theoretical probability that BB1 or BB2 is determined as the internal winning combination. Is low (in this embodiment, “α <1/400”), substantially equal (in this embodiment, “1/400 ≦ α <1/300”), or high (in this embodiment). , “1/300 ≦ α”), the probability of winning the AT operation lottery varies.

  The setting 6 AT operation lottery table shown in FIG. 13B is a table used when the set value is “6”. In the setting 6 AT operation lottery table, when “α <1/300”, the lottery value is defined so as to win with a probability of “100/256 (about 39.1%)”. Further, when “1/300 ≦ α <1/200”, the lottery value is defined so as to win with the probability of “88/256 (about 34.4%)”, and “1/200 ≦ α”. In this case, the lottery value is defined so as to win with a probability of “76/256 (about 29.7%)”. That is, when the set value is “6”, the actual BB winning rate α is lower than “about 0.40%” which is a theoretical probability that BB1 or BB2 is determined as an internal winning combination. (In this embodiment, “α <1/300”), or approximately equal (in this embodiment, “1/300 ≦ α <1/200”) or higher (in this embodiment, “ The probability of winning the AT operation lottery varies depending on whether 1/200 ≦ α ”).

  Therefore, the AT operation lottery table differs from the theoretical probability that BB1 or BB2 is determined as the internal winning combination and the probability of winning in the AT operation lottery based on the actual BB winning rate α. Adjust the number of payouts.

  Next, the setting 1 AT number lottery table and the setting 6 AT number lottery table will be described with reference to FIGS. FIG. 14A is a diagram illustrating an example of the setting 1 AT number lottery table for the gaming machine 1 in the present embodiment. FIG. 14 (2) is a diagram showing an example of an AT number lottery table for setting 6 of the gaming machine 1 in the present embodiment. The setting 1 AT number lottery table and the setting 6 AT number lottery table are collectively referred to as an AT number lottery table.

  The AT number lottery table is a lottery (AT number lottery) for determining the number of times that the AT operation state is activated (referred to as the AT number) when the AT operation lottery is won in the display command reception process (see FIG. 29) described later. It is a table used when performing. In the AT number lottery table, lottery values corresponding to one AT number, three AT times, or five AT times are defined according to the range in which the BB winning rate α is divided.

  The sub CPU 71 determines the number of ATs based on a random value acquired in advance and a lottery value defined in the AT number lottery table. Note that the method of determining the AT number based on the random number value and the lottery value defined in the AT number lottery table is the same as the effect content lottery, and thus the description thereof is omitted. In addition, when performing the AT number lottery, a random number value in the range of “0 to 255” is acquired in advance, and in the AT number lottery table, the lottery value for each range in which the level of the BB winning rate α is classified. The lottery value is defined such that the total of “256” is “256”. That is, the AT number lottery table defines a lottery value corresponding to one AT number, three AT times, or five AT times for each range in which the level of the BB winning rate α is divided. For each range in which the height is divided, the winning probability is determined that the number of ATs in the AT operation lottery is determined to be one, the number of ATs is three, or the number of ATs is five.

  The setting 1 AT number lottery table shown in FIG. 14A is a table used when the setting value is “1”. In the setting 1 AT number lottery table, when “α <1/400”, one wins with a probability of “64/256 (25.0%)” and “96/256 (37.5). %) ”Is won three times, and the lottery value is specified so that“ 96/256 (37.5%) ”is won five times. Similarly, in the case of “1/400 ≦ α <1/300”, one win is made with a probability of “128/256 (50.0%)”, and “64/256 (25.0%)”. The lottery value is defined so that 3 wins are won with the probability of 5 and 5 wins with the probability of “64/256 (25.0%)”. Further, when “1/300 ≦ α”, the winning is “192/256 (75.0%)” and the probability is “32/256 (12.5%)” 3 times. The lottery value is defined so that five wins are made with a probability of “32/256 (12.5%)”. That is, when the set value is “1”, the actual BB winning rate α is lower than “about 0.31%” which is a theoretical probability that BB1 or BB2 is determined as an internal winning combination. (In this embodiment, “α <1/400”), or substantially equal (in this embodiment, “1/400 ≦ α <1/300”) or higher (in this embodiment, “ 1/300 ≦ α ”), the probability that each AT number is determined in the AT number lottery varies.

  The setting 6 AT number lottery table shown in FIG. 14 (2) is a table used when the set value is “6”. In the setting 6 AT number lottery table, when “α <1/300”, the winning number is “32/256 (12.5%)” and the winning number is “96/256 (37.5). %) ”Is won three times, and the lottery value is specified so that“ 128/256 (50.0%) ”is won five times. Similarly, when “1/300 ≦ α <1/200” is satisfied, one win is made with a probability of “64/256 (25.0%)”, and “96/256 (37.5%)”. The lottery value is defined so that 3 wins are won with the probability of 5 and 5 wins with the probability of “96/256 (37.5%)”. In addition, when “1/200 ≦ α”, 1 wins with a probability of “128/256 (50.0%)” and 3 with a probability of “64/256 (25.0%)”. The lottery value is defined so that five wins are made with a probability of “64/256 (25.0%)”. That is, when the set value is “6”, the actual BB winning rate α is lower than “about 0.40%” which is a theoretical probability that BB1 or BB2 is determined as an internal winning combination. (In this embodiment, “α <1/300”), or approximately equal (in this embodiment, “1/300 ≦ α <1/200”) or higher (in this embodiment, “ 1/200 ≦ α ”), the probability that each AT number is determined in the AT number lottery varies.

  Therefore, the AT number lottery table varies the probability of determining each AT number in the AT number lottery based on the theoretical probability that BB1 or BB2 is determined as the internal winning combination and the actual BB winning rate α. As a result, the number of medals to be paid out is adjusted.

  The expected value table corresponding to each AT number lottery table is shown on the right side of the setting 1 AT number lottery table in FIG. 14 (1) and on the right side of the setting 6 AT number lottery table in FIG. 14 (2). The expected value table shows the expected value E of the number of ATs for each range in which the level of the BB winning rate α is divided. The expected value E is “expected value E = 1 (times) × (probability that one time is determined) +3 (times) × (probability that three times are determined) +5 (times) × (5 times is determined). Probability) ”. For example, in the setting 1 AT number lottery table, when “winning probability α <1/400” is considered, “expected value E = 1 (times) × 64/256 + 3 (times) × 96/256 + 5 (times) × 96 /256=3.25 ". That is, as shown in the expected value table, each AT number lottery table defines the lottery value so that the expected value E is higher in the range where the winning probability α is lower in the range where the BB winning rate α is divided. ing.

  Next, the setting 1 AT game number lottery table and the setting 6 AT game number lottery table will be described with reference to FIGS. FIG. 15 (1) is a diagram showing an example of the setting 1 AT game number lottery table for the gaming machine 1 in the present embodiment. FIG. 15 (2) is a diagram showing an example of an AT game number lottery table for setting 6 of the gaming machine 1 in the present embodiment. The setting 1 AT game number lottery table and the setting 6 AT game number lottery table are collectively referred to as an AT game number lottery table.

  The AT game number lottery table is used to determine the number of games that can be played in the AT operation state (referred to as AT game number) when the AT operation state is activated in a display command reception process (see FIG. 29) described later. It is a table used when performing lottery (referred to as AT game number lottery). In the AT game number lottery table, lottery values corresponding to 10 AT games, 20 AT games, or 30 AT games are defined according to the range in which the BB winning rate α is divided. .

  The sub CPU 71 determines the number of AT games based on a random value acquired in advance and a lottery value defined in the AT game number lottery table. The method for determining the AT game number based on the random number value and the lottery value defined in the AT game number lottery table is the same as the effect content lottery, and thus the description thereof is omitted. In addition, when performing an AT game number lottery, a random number value in the range of “0 to 255” is acquired in advance, and the AT game number lottery table has a BB winning rate α for each range divided into high and low. The lottery value is defined so that the sum of the lottery values is “256”. That is, the AT game number lottery table defines lottery values corresponding to 10 AT game numbers, 20 AT game numbers, or 30 AT game numbers for each range in which the BB winning rate α is divided into high and low, respectively. For each range in which the level of the BB winning rate α is divided, a winning probability is determined that 10 AT games, 20 AT games, or 30 AT games are determined in the AT game number lottery.

  The AT game number lottery table for setting 1 shown in FIG. 15 (1) is a table used when the setting value is “1”. In the AT game number lottery table for setting 1, if “α <1/400”, 10 games are won with a probability of “64/256 (25.0%)” and “96/256 (37 .5%) ”is won, and the lottery value is defined so that 30 games are won with the probability of“ 96/256 (37.5%) ”. Similarly, if “1/400 ≦ α <1/300”, 10 games are won with a probability of “96/256 (37.5%)” and “64/256 (25.0%) The lottery value is defined so that 20 games are won with a probability of “96” and 30 games are won with a probability of “96/256 (37.5%)”. If “1/300 ≦ α”, 10 games win with a probability of “128/256 (50.0%)” and 20 with a probability of “64/256 (25.0%)”. The lottery value is defined so that 30 games are won with a probability of “64/256 (25.0%)”. That is, when the set value is “1”, the actual BB winning rate α is lower than “about 0.31%” which is a theoretical probability that BB1 or BB2 is determined as an internal winning combination. (In this embodiment, “α <1/400”), or substantially equal (in this embodiment, “1/400 ≦ α <1/300”) or higher (in this embodiment, “ 1/300 ≦ α ”), the probability that each AT game number is determined in the AT game number lottery varies.

  The setting 6 AT game number random determination table shown in FIG. 15B is a table used when the setting value is “6”. In the AT game number lottery table for setting 6, if “α <1/400”, 10 games are won with a probability of “32/256 (12.5%)” and “96/256 (37 .5%) ”is won and 20 lottery values are defined so that“ 128/256 (50.0%) ”is 30 games. Similarly, if “1/400 ≦ α <1/300”, 10 games are won with a probability of “64/256 (25.0%)”, and “96/256 (37.5%) The lottery value is defined so that 20 games are won with a probability of “96” and 30 games are won with a probability of “96/256 (37.5%)”. When “1/300 ≦ α”, 10 games are won with a probability of “96/256 (37.5%)” and 20 with a probability of “64/256 (25.0%)”. The lottery value is defined so that 30 games are won with a probability of “96/256 (37.5%)”. That is, when the set value is “6”, the actual BB winning rate α is lower than “about 0.40%” which is a theoretical probability that BB1 or BB2 is determined as an internal winning combination. (In this embodiment, “α <1/300”), or approximately equal (in this embodiment, “1/300 ≦ α <1/200”) or higher (in this embodiment, “ 1/200 ≦ α ”), the probability that each AT game number is determined in the AT game number lottery varies.

  Therefore, the AT game number lottery table has a probability of determining each AT game number in the AT game number lottery based on the theoretical probability that BB1 or BB2 is determined as an internal winning combination and the actual BB winning rate α. The number of medals to be paid out is adjusted by differentiating.

  In addition, on the right side of the AT game number lottery table for setting 1 in FIG. 15 (1) and the right side of the AT game number lottery table for setting 6 in FIG. 15 (2), an expected value table corresponding to each AT game number lottery table. Indicates. The expected value table shows the expected value E of the number of AT games for each range in which the level of the BB winning rate α is divided. The expected value E is “expected value E = 10 (game) × (probability that 10 games will be determined) +20 (game) × (probability that 20 games will be determined) +20 (game) × (30 games are determined). Probability) ”. For example, in the AT game lottery table for setting 1, when “winning probability α <1/400” is considered, “expected value E = 10 (game) × 64/256 + 20 (game) × 96/256 + 30 (game) × 96/256 = 21.25 ". That is, as shown in the expected value table, each AT game number lottery table defines the lottery value so that the expected value E is higher in the range where the winning probability α is lower in the range where the BB winning rate α is divided. is doing.

  Next, the control operation of the main CPU 31 of the main control circuit 60 will be described with reference to the flowcharts shown in FIGS.

  First, with reference to FIG. 16, the reset interrupt process by the main CPU 31 of the main control circuit 60 will be described. FIG. 16 is a diagram illustrating a flowchart of reset interrupt processing by the main CPU 31 performed by the main control circuit 60 of the present embodiment. Further, the main CPU 31 generates a reset interrupt when power is turned on and a voltage is applied to the reset terminal, and the reset interrupt process stored in the ROM 32 is sequentially performed based on the occurrence of the interrupt. It is configured as follows.

  First, when the power is turned on, the main CPU 31 performs initialization (step S1). In the present embodiment, in the process of step S <b> 1, the main CPU 31 transmits a power-on command to the sub control circuit 70.

  Next, the main CPU 31 clears the designated RAM area at the end of the game (step S2). Specifically, the main CPU 31 erases data in the writable area in the RAM 33 used for the previous unit game, writes parameters necessary for the current unit game in the writable area in the RAM 33, Specify the start address to the sequence program.

  Next, the main CPU 31 performs a bonus operation monitoring process which will be described later with reference to FIG. 17 (step S3). This bonus operation monitoring process is a process for generating an RB gaming state when the gaming state is not the RB gaming state in the BB1 operating state or the BB2 operating state.

  Next, the main CPU 31 performs a medal acceptance / start check process which will be described later with reference to FIG. 18 (step S4). In the medal acceptance / start check process, the insertion number counter is updated by checking the medal sensor 22S and the BET switches 11S, 12S, 13S, etc., and the input of the start switch 6S is checked.

  Next, when determining that the start switch 6S is turned on, the main CPU 31 extracts a random number value for determining an internal winning combination (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.

  Next, the main CPU 31 performs a gaming state monitoring process (step S6). In this 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 BB1 operating flag, the BB2 operating flag, the RB operating flag, and the MB operating flag. , Set in the RAM 33.

  Next, the main CPU 31 performs an internal lottery process which will be described later with reference to FIG. 19 (step S7). In this internal lottery process, the main CPU 31 refers to the internal lottery table determination table (see FIG. 5), the internal lottery table (see FIG. 6), and the internal winning combination determination table (see FIG. 7) to play an internal symbol combination. decide.

  Next, the main CPU 31 transmits a start command to the sub control circuit 70 (step S8). The start command includes, for example, information such as game state information and internal winning combination information.

  Next, the main CPU 31 requests the start of rotation of all reels (step S9). For example, the main CPU 31 performs processing such as turning on a rotation start request flag set in the RAM 33. When the start of rotation of all reels is requested, rotation start processing and acceleration control processing of the reels 3L, 3C, and 3R are performed.

  Next, the main CPU 31 performs a reel stop control process which will be described later with reference to FIG. 20 (step S10). In the reel stop control process, the main CPU 31 stops the rotation of the reels 3L, 3C, and 3R based on a stop signal output from the stop switches 7LS, 7CS, and 7RS by the player's stop operation.

  Next, when all the rotations of the reels 3L, 3C, and 3R are stopped, the main CPU 31 determines the display combination based on the displayed symbol combination and determines the number of medals to be paid out (step S11). . In this process, the main CPU 31 determines the display combination based on the code number of the symbol displayed on the active line and the symbol combination table (see FIG. 8). 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.

  Next, the main CPU 31 transmits a display command to the sub control circuit 70 (step S12). The display command includes information such as display combination information for specifying a display combination.

  Next, the main CPU 31 performs medal payout processing (step S13). In this 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 credit counter 19 displays the value of the credit counter. In the payout mode, the main CPU 31 controls the hopper 40 by the hopper drive circuit 41 based on the payout number to pay out medals.

  Next, when the bonus end number counter is “1” or more, the main CPU 31 subtracts the number of medals paid out in the process of step S13 from the value of the bonus end number counter (step S14).

  Next, the main CPU 31 determines whether or not any of the BB1 operating flag, the BB2 operating flag, the RB operating flag, and the MB operating flag is on (step S15). At this time, when the main CPU 31 determines that the BB1 operating flag, the BB2 operating flag, the RB operating flag, or the MB operating flag is on, a bonus end check process described later with reference to FIG. (Step S16), the process proceeds to step S17. On the other hand, when the main CPU 31 determines that the BB1 operating flag, the BB2 operating flag, the RB operating flag, or the MB operating flag is not on, that is, the BB1 operating flag, the BB2 operating flag, and the RB operating flag. If it is determined that both the MB operating flag is OFF, the process proceeds to step S17.

  Next, when the main CPU 31 determines that the BB1 operating flag, the BB2 operating flag, the RB operating flag, or the MB operating flag is not on in the process of step S15, or when the process of step S16 is completed. Then, bonus operation check processing described later with reference to FIG. 22 is performed (step S17). When this process ends, the main CPU 31 proceeds to the process of step S2.

  As described above, the main CPU 31 executes the process from step S2 to step S17 as the process in the unit game, and when the process in step S17 ends, the main CPU 31 proceeds to the process in step S2 to execute the process in the next unit game. .

  Next, the bonus operation monitoring process will be described with reference to FIG. FIG. 17 is a diagram showing a flowchart of the bonus operation monitoring process performed in the main control circuit 60 of the present embodiment.

  First, the main CPU 31 determines whether or not the BB1 operating flag or the BB2 operating flag is on (step S31). At this time, when the main CPU 31 determines that the BB1 operating flag or the BB2 operating flag is not on, the main CPU 31 ends the bonus operation monitoring process. On the other hand, when the main CPU 31 determines that the BB1 operating flag or the BB2 operating flag is on, the main CPU 31 then determines whether or not the RB operating flag is on (step S32).

  When the main CPU 31 determines in the process of step S32 that the RB operating flag is ON, the main CPU 31 ends the bonus operation monitoring process. On the other hand, when determining that the RB operating flag is not on, the main CPU 31 performs RB operating processing based on the bonus operating table (see FIG. 9) (step S33). Specifically, the main CPU 31 sets “12” in the possible game number counter, sets “8” in the possible winning number counter, and turns on the RB operating flag based on the bonus operating time table. . After completing this process, the main CPU 31 ends the bonus operation monitoring process.

  That is, the main CPU 31 always activates the RB gaming state when the bonus operation monitoring process is in the BB1 operation state or the BB2 operation state. For example, in the previous unit game, when either the game possible number counter or the winning possible number counter becomes “0” and the RB gaming state is ended, the main CPU 31 continues to be in the BB operating state. Then, the RB gaming state is activated again. When the main CPU 31 ends the bonus operation monitoring process, the main CPU 31 proceeds to the process of step S4 in FIG.

  Next, the medal acceptance / start check process will be described with reference to FIG. FIG. 18 is a flowchart of the medal acceptance / start check process performed by the main control circuit 60 of the present embodiment.

  First, the main CPU 31 determines whether or not the value of the automatic insertion counter is “0” (step S41). At this time, when the main CPU 31 determines that the value of the automatic insertion counter is not “0”, the main CPU 31 proceeds to the processing of step S43. Here, the automatic insertion counter is data for identifying whether or not a replay has been established in the previous unit game. On the other hand, when the main CPU 31 determines that the value of the automatic insertion counter is “0”, the main CPU 31 then permits passage of medals (step S42), and proceeds to the processing of step S45.

  Next, when the main CPU 31 determines in the process of step S41 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 sub-controls the bet command. The data is transmitted to the circuit 70 (step S44). Here, the main CPU 31 clears the automatic insertion counter when performing the process of step S43. The inserted number counter is data for counting the inserted number. Further, the bet command includes information such as information on the number of inserted coins.

  Next, when the main CPU 31 finishes the process of step S42, finishes the process of step S44, determines that the value of the input number counter is not “1” or more in the process of step S55 described later, or If it is determined in step S56 described later that the start switch is not on, it is then determined whether or not a medal has passed (step S45). At this time, when the main CPU 31 determines that the medal has not passed, the process proceeds to step S51. 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 S46). In the present embodiment, since the maximum number of inserted sheets is determined to be 3, the maximum value of the inserted sheet counter is “3”.

  When the main CPU 31 determines in the process of step S46 that the inserted number counter is the maximum value, it sets “1” as the value of the credit counter (step S50), and proceeds to the process of step S51. Here, the credit counter is data for counting the number of credited medals. On the other hand, when the main CPU 31 determines that the insertion number counter is not the maximum value, it then adds “1” to the value of the insertion number counter (step S47). Next, the main CPU 31 sets “5” in the effective line counter (step S48) and transmits a medal insertion command to the sub control circuit 70 (step S49), and proceeds to the processing of step S51. Here, the valid line counter is data for specifying the number of valid lines, and the display combination is searched based on the counter.

  Next, when the main CPU 31 determines that the medal has not passed in the process of step S45, it determines whether or not the operation of the BET button is detected after performing the process of step S49 or the process of step S50. (Step S51). At this time, when the main CPU 31 determines that the operation of the BET button has not been detected, the main CPU 31 proceeds to the process of step S55. On the other hand, when determining that the operation of the BET button has been detected, the main CPU 31 then adds a value corresponding to the detected BET button to the value of the insertion number counter (step S52). Next, the main CPU 31 sets “5” in the valid line counter (step S53) and transmits a medal insertion command to the sub control circuit 70 (step S54), and proceeds to the processing of step S55.

  Next, the main CPU 31 determines whether or not the value of the insertion number counter is “1” or more (step S55). At this time, if the main CPU 31 determines that the value of the insertion number counter is not “1” or more, it proceeds to the processing of step S45. On the other hand, when the main CPU 31 determines that the value of the insertion number counter is “1” or more, it next determines whether or not the start switch 6S is on (step S56).

  When the main CPU 31 determines in the process of step S56 that the start switch 6S is not on, the main CPU 31 proceeds to the process of step S45. On the other hand, when determining that the start switch 6S is on, the main CPU 31 prohibits the passage of medals (step S57) and ends the medal acceptance / start check process. When the main CPU 31 finishes the medal acceptance / start check process, the main CPU 31 proceeds to the process of step S5 in FIG.

  Next, an internal lottery process will be described with reference to FIG. FIG. 19 is a diagram showing a flowchart of an internal lottery process performed by the main control circuit 60 of the present embodiment.

  First, the main CPU 31 refers to the internal lottery table determination table (see FIG. 5), and determines the type of the internal lottery table and the number of lotteries based on the gaming state and the set value (step S61).

  Next, the main CPU 31 determines whether or not the carryover combination storage area is “00000000” (step S62). That is, the main CPU 31 determines whether the BB1 carryover state, the BB2 carryover state, or the MB carryover state. When the main CPU 31 determines that the carryover combination storage area is “00000000”, that is, when the main CPU 31 determines that the carryover state is not the BB1 carryover state, the BB2 carryover state, or the MB carryover state, the processing of step S64 is performed. Transition.

  On the other hand, when the main CPU 31 determines in the process of step S62 that the carryover combination storage area is not “00000000”, that is, any carryover state of BB1 carryover state, BB2 carryover state, or MB carryover state. The number of lotteries is changed to “6” (step S63). By changing the number of lotteries to “6”, the main CPU 31 sets the bonus combination such as BB1, BB2, or MB again in the subsequent processing even though it is in the BB1 carryover state, BB2 carryover state, or MB carryover state. Avoid deciding to win.

  Next, when determining that the carryover combination storage area is “00000000” in the process of step S62, the main CPU 31 changes the number of lotteries to “6” in the process of step S63, or step S69 described later. If it is determined that the number of lotteries is not “0” in this process, then the same value as the number of lotteries is set in the winning number (step S64).

  Next, the main CPU 31 refers to the determined internal lottery table (see FIG. 6), and the random number value stored in the random value storage area of the RAM 33 is equal to or greater than the lower limit value determined based on the winning number and the inserted number counter. And it is discriminate | determined whether it is below an upper limit (step S65). At this time, when the main CPU 31 determines that the random number value is equal to or lower than the lower limit value or equal to or higher than the upper limit value (that is, out of the winning range), the main CPU 31 proceeds to the process of step S68. On the other hand, when the main CPU 31 determines that the random number value is greater than or equal to the lower limit value and less than or equal to the upper limit value (that is, within the winning range), the main CPU 31 refers to the internal winning combination determination table (see FIG. 7) and based on the winning number The internal winning combination is determined (step S66).

  Next, the main CPU 31 stores, in the internal winning combination storage area, the logical sum of the data indicating the internal winning combination determined in the process of step S66 and the internal winning combination storing area (step S67). Specifically, the main CPU 31 stores the data of the internal symbol combination 1 in the internal symbol combination determination table and the internal symbol combination 1 storage area in the internal symbol combination 1 storage area, The logical sum of the data of the internal symbol combination 2 and the internal symbol combination 2 storage area is stored in the internal symbol combination 2 storage area.

  Next, when the main CPU 31 determines in the process of step S65 that the random number value is less than or equal to the lower limit value or greater than or equal to the upper limit value (that is, outside the winning range), or when the process of step S67 is finished. “1” is subtracted from the number of lotteries (step S68).

  Next, the main CPU 31 determines whether or not the number of lotteries is “0” (step S69). At this time, when the main CPU 31 determines that the number of lotteries is “0”, the main CPU 31 proceeds to the process of step S70. On the other hand, when determining that the number of lotteries is not “0”, the main CPU 31 proceeds to the process of step S64. Thereafter, the main CPU 31 repeats the processing from step S64 to step S68 (referred to as “repetition processing”) until the number of lotteries becomes “0”.

  Next, when the main CPU 31 determines that the number of lotteries is “0” in the process of step S69, the main CPU 31 then stores the logical sum of the internal winning combination 2 storage area and the carryover combination storage area in the carryover combination storage area ( Step S70).

  Next, the main CPU 31 stores the logical sum of the internal winning combination 2 storage area and the carryover combination storing area in the internal winning combination 2 storage area (step S71), and then determines whether or not the gaming state is the MB gaming state. A determination is made (step S72). At this time, when the main CPU 31 determines that the gaming state is not the MB gaming state, the main CPU 31 ends the internal lottery process. On the other hand, when the main CPU 31 determines that the gaming state is the MB gaming state, the main CPU 31 sets “1” to the bits “0” to “4” of the internal winning combination 1 storage area (step S73), and the internal lottery process End.

  When the main CPU 31 finishes the internal lottery process, the main CPU 31 proceeds to the process of step S8 in FIG.

  Here, the main CPU 31 performs a lottery of an internal winning combination by executing the above-described repetitive processing. Specifically, the main CPU 31 determines a winning number by sequentially determining which winning range of the internal lottery table includes the random number value in the RAM 33, and determines the winning combination corresponding to the winning number. Decide on a role.

  On the other hand, when the main CPU 31 determines that the random number value stored in the random number value storage area of the RAM 33 is not included in any winning range of the internal lottery table, the main CPU 31 executes the processes of steps S66 and S67. The process will be repeated without doing so. In this case, since the internal winning combination is not determined in the repetitive processing, and the internal winning combination storing area and the carryover winning combination storing area are not edited, the internal winning combination 1 storing area and the internal winning combination 2 storing area are It is “00000000”. However, in the carryover combination storage area, if the BB1 carryover state, the BB2 carryover state, or the MB carryover state, “1” is set in the corresponding bits of the bits “0” to “2”. As described above, when the process is repeated without executing the processes of step S66 and step S67, that is, even when the process is out of the internal lottery, the internal winning combination 2 storage area and the carryover combination In order to make the bit pattern of the storage area the same bit pattern, the process of step S71 is performed.

  Next, the reel stop control process will be described with reference to FIG. FIG. 20 is a diagram showing a flowchart of the reel stop control process performed by the main control circuit 60 of the present embodiment.

  First, the main CPU 31 determines whether or not a valid stop switch has been pressed (step S81). Specifically, the main CPU 31 determines whether stop switches 7LS, 7CS, and 7RS corresponding to the rotating reels 3L, 3C, and 3R are turned on based on a stop operation by the player. At this time, when the main CPU 31 determines that an effective stop switch is not pressed, the main CPU 31 executes the process of step S81 again. That is, the main CPU 31 repeats the process of step S81 until an effective stop switch is pressed. On the other hand, when the main CPU 31 determines in step S81 that the effective stop switch has been pressed, the main CPU 31 invalidates the pressing operation of the stop button (step S82).

  Next, the main CPU 31 sets “5” as the number of symbol checks (step S83).

  Next, the main CPU 31 determines whether or not the gaming state is the MB gaming state (step S84). At this time, when the main CPU 31 determines that the gaming state is not the MB gaming state, the main CPU 31 proceeds to the processing of step S87. On the other hand, when the main CPU 31 determines that the gaming state is the MB gaming state, it then determines whether or not the left stop button 7L has been pressed (step S85).

  When determining that the left stop button 7L has not been pressed in the process of step S85, the main CPU 31 proceeds to the process of step S87. On the other hand, when it is determined that the left stop button 7L has been pressed, the number of symbol checks is changed to “2” (step S86).

  Next, when the main CPU 31 determines that the gaming state is not the MB gaming state in the process of step S84, determines that the left stop button 7L is not pressed in the process of step S85, or After performing the process of S86, the symbol position with the highest priority in the range of the symbol check count from the symbol position corresponding to the symbol counter is searched (step S87). Specifically, the main CPU 31 determines whether or not there is a symbol constituting a combination of symbols related to the internal winning combination in the symbols within the range of the number of symbol checks from the symbol position corresponding to the symbol counter. . At this time, when there are a plurality of symbols constituting a combination of symbols related to the internal winning combination, a symbol with a high priority is searched. The priorities are defined as follows. First, the first priority is replay, and then the second priority is a bonus combination. The third and higher priorities are related to the payout of medals, and among them, the priority is higher in descending order of the number of medals to be paid out. In addition, when there are a plurality of symbols with the highest priority, any of them may be selected, but a priority when selecting in advance may be defined and selected according to the priority.

  Next, the main CPU 31 determines the number of sliding frames based on the search result (step S88). Here, the number of sliding frames is the number of frames from when the stop operation is detected by the stop switch 7S until the rotation of the corresponding reel stops.

  In this embodiment, when the gaming state is a gaming state other than the MB gaming state, the rotation of the corresponding reel is stopped within 190 milliseconds after the stop signal based on the stop operation is output by the stop switch 7S. In this case, the number of sliding symbols of any value from “0” to “4” is determined. For this reason, “5” is set as the symbol check count in the process of step S83, and the position of the symbol with the highest priority within this range is searched. On the other hand, when the gaming state is the MB gaming state, the stop switch 7LS is used to stop at least one of the three reels 3L, 3C, 3R (in this embodiment, only the left reel 3L is applied). Control is performed to stop the rotation of the corresponding reel within 75 milliseconds after the stop signal based on is output. At this time, the sliding piece having a value of “0” or “1” is used. The number is determined. For this reason, “2” is set as the number of symbol checks in the process of step S86, and the position of the symbol with the highest priority within this range is searched.

  By determining the number of sliding symbols in this way, for example, when a pressing operation on the stop button 7 is performed, the symbol position corresponding to the symbol counter of the corresponding reel is “0” and determined. If the number of sliding symbols is “4”, control for stopping the rotation of the reel is performed so that the symbol related to the symbol position “4” is displayed in the middle of the corresponding display window. The symbol position indicated by the value of the symbol counter corresponding to the symbol at the position of the center line 8c when the pressing operation on the stop button 7 is performed is referred to as the “stop start position”, and the stop start position. The stop control for stopping the symbol within the range of the number of sliding symbols from the center line 8c to the center line 8c is referred to as “retraction”. Furthermore, the symbol position where the number of sliding frames is drawn from the stop start position and stopped is referred to as a “stop control position”.

  Next, the main CPU 31 shifts to a stop control position wait (step S89). Specifically, the main CPU 31 performs the reel control process (step S143) of an interrupt process (see FIG. 23) described later based on the stop control position determined by the number of sliding symbols determined as described above. The reel stop control process is stopped. When the main CPU 31 stops the corresponding reel by the reel control process (step S143) of the interrupt process, the main CPU 31 restarts the reel stop control process.

  Next, the main CPU 31 transmits a reel stop command to the sub control circuit 70 (step S90). The reel stop command includes data indicating the type of the stopped reel.

  Next, the main CPU 31 determines whether or not there is a stop button 7 for which the pressing operation is valid (step S91). At this time, when the main CPU 31 determines that there is a stop button 7 for which the pressing operation is valid, the main CPU 31 proceeds to the process of step S81. That is, the main CPU 31 repeats the processing from step S81 to step S90 until it is determined that all reels have stopped. On the other hand, when the main CPU 31 determines that there is no stop button 7 for which the pressing operation is valid, the main CPU 31 ends the reel stop control process, and proceeds to the process of step S11 in FIG.

  Next, the bonus end check process will be described with reference to FIG. FIG. 21 is a flowchart of the bonus end check process performed by the main control circuit 60 of the present embodiment.

  First, the main CPU 31 determines whether or not the RB operating flag is on (step S101). At this time, when the main CPU 31 determines that the RB operation flag is on, the main CPU 31 proceeds to the process of step S103. On the other hand, when it is determined that the RB operating flag is not on, it is then determined whether or not the value of the bonus end number counter is “0” (step S102).

  When the main CPU 31 determines in the process of step S102 that the value of the bonus end number counter is not “0”, the main CPU 31 ends the bonus end check process. On the other hand, when the main CPU 31 determines that the value of the bonus end number counter is “0”, the main CPU 31 proceeds to the process of step S105.

  Next, when the main CPU 31 determines in the process of step S101 that the RB operating flag is on, it then determines whether or not a winning has been established (step S103). At this time, when the main CPU 31 determines that no winning has been established, the main CPU 31 proceeds to the processing of step S109. On the other hand, when the main CPU 31 determines that a winning has been established, it then determines whether or not the value of the bonus end number counter is “0” (step S104).

  When the main CPU 31 determines in the process of step S104 that the value of the bonus end number counter is not “0”, the main CPU 31 proceeds to the process of step S107. On the other hand, when the main CPU 31 determines that the value of the bonus end number counter is “0”, the main CPU 31 proceeds to the process of step S105.

  Next, the main CPU 31 determines that the value of the bonus end number counter is “0” in the process of step S102, or the value of the bonus end number counter is “0” in the process of step S104. In some cases, next, processing at the end of BB and MB is performed (step S105). Specifically, the main CPU 31 turns off the BB1 operating flag, the BB2 operating flag, or the MB operating flag that are on, and when the RB operating flag is on, the main CPU 31 is operating. Turn off the flag.

  Next, the main CPU 31 transmits a bonus end command to the sub-control circuit 70 (step S106). When the main CPU 31 transmits a bonus end command to the sub-control circuit 70, the main CPU 31 ends the bonus end check process.

  On the other hand, when the main CPU 31 determines that the value of the bonus end number counter is not “0” in the process of step S104, the main CPU 31 then subtracts “1” from the value of the possible winning number counter (step S107).

  Next, the main CPU 31 determines whether or not the value of the winning possible number counter subtracted in the process of step S107 is “0” (step S108). At this time, when the main CPU 31 determines that the value of the number-of-winning counter is “0”, the main CPU 31 proceeds to the process of step S111. On the other hand, when the main CPU 31 determines that the value of the possible winning number counter is not “0”, the main CPU 31 proceeds to the process of step S109.

  Next, when the main CPU 31 determines that a winning is not established in the process of step S103 or when it is determined that the value of the winning possible number counter is not “0” in the process of step S108, “1” is subtracted from the value of the possible number counter (step S109).

  Next, the main CPU 31 determines whether or not the value of the possible game number counter subtracted in the process of step S109 is “0” (step S110). At this time, when the main CPU 31 determines that the value of the possible game number counter is “0”, the main CPU 31 proceeds to the process of step S111. On the other hand, when the main CPU 31 determines that the value of the possible game number counter is not “0”, the main CPU 31 ends the bonus end check process.

  Next, the main CPU 31 determines that the value of the possible winning number counter is “0” in the process of step S108, or determines that the value of the possible game number counter is “0” in the process of step S110. Then, the RB end process is performed (step S111). Specifically, the main CPU 31 performs processing such as turning off the RB operating flag.

  When the main CPU 31 finishes the bonus end check process, the main CPU 31 proceeds to the process of step S17 in FIG.

  Next, the bonus operation check process will be described with reference to FIG. FIG. 22 is a diagram showing a flowchart of the bonus operation check process performed in the main control circuit 60 of the present embodiment.

  First, the main CPU 31 determines whether or not the display combination is BB1 (step S121). At this time, when the main CPU 31 determines that the display combination is not BB1, the process shifts to step S123. On the other hand, when the main CPU 31 determines that the display combination is BB1, the main CPU 31 performs BB1 operation processing based on the bonus operation time table (step S122). Specifically, the main CPU 31 sets “345” in the bonus end number counter based on the bonus operation time table, and turns on the BB1 operating flag. When this process is finished, the main CPU 31 proceeds to the process of step S127.

  Next, when determining that the display combination is not BB1 in the process of step S121, the main CPU 31 next determines whether or not the display combination is BB2 (step S123). At this time, when the main CPU 31 determines that the display combination is not BB2, the process shifts to step S125. On the other hand, when the main CPU 31 determines that the display combination is BB2, the main CPU 31 performs BB2 operation processing based on the bonus operation time table (step S124). Specifically, the main CPU 31 sets “345” in the bonus end number counter based on the bonus operation time table, and turns on the BB2 operating flag. When this process is finished, the main CPU 31 proceeds to the process of step S127.

  When determining that the display combination is not BB2 in the process of step S123, the main CPU 31 determines whether or not the display combination is MB (step S125). At this time, when the main CPU 31 determines that the display combination is not MB, the main CPU 31 proceeds to the process of step S129. On the other hand, when the main CPU 31 determines that the display combination is MB, it performs MB operation processing based on the bonus operation table (step S126). Specifically, the main CPU 31 sets “150” in the bonus end number counter based on the bonus operation time table and turns on the MB operating flag. When this process is finished, the main CPU 31 proceeds to the process of step S127.

  When the main CPU 31 performs the BB1 operation process in the process of step S122, the BB2 operation process in the process of step S124, or the MB operation process in the process of step S126, The storage area is cleared (step S127), and a bonus start command is transmitted to the sub-control circuit 70 (step S128), and the bonus operation check process is terminated.

  On the other hand, when the main CPU 31 determines in the process of step S125 that the display combination is not MB, it then determines whether or not the display combination is replay (step S129). At this time, when the main CPU 31 determines that the display combination is not replay, the main CPU 31 ends the bonus operation check process. On the other hand, when determining that the display combination is replay, the main CPU 31 copies the insertion number counter to the automatic insertion counter (step S130) and ends the bonus operation check process.

  When the main CPU 31 ends the bonus operation check process, the main CPU 31 proceeds to the process of step S2 in FIG.

  Next, with reference to FIG. 23, an interrupt process under the control of the main CPU will be described. FIG. 23 is a diagram illustrating a flowchart of interrupt processing performed by the main control circuit 60 in the main control circuit 60 of the present embodiment. Further, the interrupt process under the control of the main CPU is an interrupt process that occurs every predetermined period (for example, 1.1173 milliseconds).

  First, the main CPU 31 interrupts the program being executed before calling the interrupt process under the control of the main CPU, and saves the address indicating the interrupted position and the values of various registers in a predetermined area of the RAM 33. (Step S141). This is because when the interrupt process under the control of the main CPU is completed, the address indicating the interrupted position of the saved program and the values of various registers are restored, and the program is continuously executed from the point of interruption. It is.

  Next, the main CPU 31 performs input port check processing (step S142). Specifically, the main CPU 31 checks signals from each switch.

  Next, the main CPU 31 performs a reel control process (step S143). Specifically, when there is a reel rotation start request, the main CPU 31 starts the rotation of the reels 3L, 3C, and 3R, and performs control for rotating at a constant speed. Further, when the stop control position is determined by determining the number of sliding frames in the reel stop control process (see FIG. 20), the main CPU 31 indicates the stop control position by the value of the symbol counter of the corresponding reel. When the value becomes the same as the value, control is performed to stop the reel. For example, when the value indicating the stop control position is “4”, the main CPU 31 performs control for stopping the corresponding reel when the value of the symbol counter becomes “4”.

  Next, the main CPU 31 performs a lamp / 7SEG drive control process (step S144). Specifically, the main CPU 31 drives and controls the BET lamps 9 a, 9 b, 9 c and the WIN lamp 17 via the lamp driving circuit 45. Thereby, the BET lamps 9a, 9b, 9c and the WIN lamp 17 are turned on and off. Further, the main CPU 31 drives and controls the payout number display unit 18 and the credit display unit 19 via the display unit drive circuit 48. As a result, various information (such as the number of credits) is displayed on the payout number display unit 18 and the credit display unit 19.

  Next, the main CPU 31 refers to the value saved in the RAM 33 in the process of step S141, and restores the register (step S145). When this process ends, the interrupt process under the control of the main CPU is ended, and the program interrupted by the occurrence of the interrupt process under the control of the main CPU is continuously executed.

  Next, the operation of the sub control circuit 70 will be described with reference to the flowcharts shown in FIGS.

  First, with reference to FIG. 24, main board communication processing by the sub CPU 71 will be described. FIG. 24 is a diagram showing a flowchart of main board communication processing by the sub CPU 71 of this embodiment.

  First, the sub CPU 71 receives a command transmitted from the main control circuit 60 (step S201).

  Next, the sub CPU 71 extracts type information from the received command (step S202).

  Next, the sub CPU 71 determines whether or not a command of a type different from the previously received command has been received (step S203). At this time, if the sub CPU 71 determines that a command of the same type as the previously received command has been received, the sub CPU 71 proceeds to the process of step S201. On the other hand, when the sub CPU 71 determines that a command of a type different from the previously received command is received, the sub CPU 71 stores the message in the message queue based on the received command. Here, the message queue is a mechanism for exchanging information between processes. In the present embodiment, game information is stored in the message queue as a message by the process of step S204, and an effect registration described later is performed. The game information is transferred to the process (see FIG. 25).

  Next, with reference to FIG. 25, the effect registration process by the sub CPU 71 will be described. FIG. 25 is a flowchart of the effect registration process performed by the sub CPU 71 of this embodiment.

  First, the sub CPU 71 extracts a message from the message queue (step S211). Next, the sub CPU 71 determines whether or not there is a message in the message queue (step S212). At this time, when the sub CPU 71 determines that there is no message in the message queue, the sub CPU 71 proceeds to the process of step S215. On the other hand, when determining that there is a message in the message queue, the sub CPU 71 copies the game information from the message to the SDRAM 73 (step S213), and then performs an effect content determination process described later with reference to FIG. 26 (step S214). ).

  Next, the sub CPU 71 registers animation data when it is determined in the process of step S212 that there is no message in the message queue, or after the effect content determination process of step S214 (step S215). Specifically, the sub CPU 71 registers animation data based on the effect data set in the effect content determination process, and causes the liquid crystal display device 5 to display an image. More specifically, the sub CPU 71 transmits an image display command to the rendering processor 74 based on the effect data determined in the effect content determination process. The rendering processor 74 selects appropriate image data from the image data developed in the drawing SDRAM 75 based on the received image display command, determines the display position and size of the image data, and determines the image data. Are stored in one frame buffer area provided in the drawing SDRAM 75. The rendering processor 74 performs a bank switching process for switching the display image data area and the write image data area in the frame buffer area at predetermined intervals. In the bank switching process, the rendering processor 74 outputs the image data written in the write image data area to the liquid crystal display device 5, replaces the display image data area with the write image data area, and then displays the next image to be displayed. Write data.

  Next, the sub CPU 71 registers LED / sound data (step S216). Specifically, the sub CPU 71 registers LED / sound data on the basis of the effect data set in the effect content determination process, turns on the LED 101 via the sound / lamp control circuit 90, and the speaker 21L. , 21R is caused to output sound. When this process ends, the sub CPU 71 returns to the process of step S211.

  Next, with reference to FIG. 26, an effect content determination process by the sub CPU 71 will be described. FIG. 26 is a diagram showing a flowchart of effect content determination processing by the sub CPU 71 of the present embodiment.

  First, the sub CPU 71 determines whether or not a start command has been received (step S221). At this time, when the sub CPU 71 determines that the start command has not been received, the sub CPU 71 proceeds to the process of step S223. On the other hand, when determining that the start command has been received, the sub CPU 71 performs an effect lottery process described later with reference to FIG. 27 (step S222), and ends the effect content determination process.

  Next, when the sub CPU 71 determines that a start command has not been received in the process of step S221, it then determines whether a reel stop command has been received (step S223). At this time, if the sub CPU 71 determines that the reel stop command has not been received, the sub CPU 71 proceeds to the process of step S225. On the other hand, when determining that the reel stop command has been received, the sub CPU 71 sets effect data based on the reel type or the like (step S224), and ends the effect content determination process.

  Next, when determining that the reel stop command has not been received in the process of step S223, the sub CPU 71 then determines whether or not a display command has been received (step S225). At this time, if the sub CPU 71 determines that a display command has not been received, the sub CPU 71 proceeds to the process of step S227. On the other hand, when determining that the display command has been received, the sub CPU 71 performs a display command reception process described later with reference to FIG. 29 (step S226), and ends the effect content determination process.

  Next, when the sub CPU 71 determines in step S225 that the display command has not been received, it then determines whether or not a bonus start command has been received (step S227). At this time, if the sub CPU 71 determines that the bonus start command has not been received, the sub CPU 71 proceeds to the process of step S230. On the other hand, when determining that the bonus start command has been received, the sub CPU 71 sets effect data according to the type of bonus game (step S228), and a game held in the sub control circuit 70 according to the type of bonus game. The operating state information (sub) is changed to the BB operating state or the MB gaming state (step S229). The sub CPU 71 ends the effect content determination process when this process is finished.

  Next, when determining that the bonus start command has not been received in the process of step S227, the sub CPU 71 then determines whether or not a bonus end command has been received (step S230). At this time, if the sub CPU 71 determines that the bonus end command has not been received, the sub CPU 71 proceeds to the process of step S233. On the other hand, when determining that the bonus end command has been received, the sub CPU 71 sets effect data for ending the bonus game (step S231) and also stores game / operation state information (sub) held in the sub control circuit 70. The game state is changed to the general game state (step S232). The sub CPU 71 ends the effect content determination process when this process is finished.

  Next, when determining that the bonus start command has not been received in the process of step S227, the sub CPU 71 then determines whether or not a power-on command has been received (step S233). At this time, when the sub CPU 71 determines that the power-on command has not been received, the sub CPU 71 proceeds to the process of step S235. On the other hand, when determining that the power-on command has been received, the sub CPU 71 sets “0” in the game number counter and the BB winning number counter (step S234), and ends the effect content determination process. Here, the game number counter is a counter for counting the number of games since the power is turned on, and the BB winning number counter is a BB for which BB1 or BB2 is determined as an internal winning combination after the power is turned on. This is a counter for counting the number of wins.

  Next, when the sub CPU 71 determines that the power-on command has not been received in the process of step S233, the sub CPU 71 then sets effect data according to the received command (step S235). The sub CPU 71 ends the effect content determination process when this process is finished.

  When the sub CPU 71 ends the effect content determination process, the sub CPU 71 proceeds to the process of step S215 of the effect registration process (see FIG. 25).

  Next, with reference to FIG. 27, the effect lottery processing by the sub CPU 71 will be described. In addition, FIG. 27 is a figure which shows the flowchart of the effect lottery process by the sub CPU71 of this embodiment.

  First, the sub CPU 71 determines whether or not it is in the AT operation state (step S241). Specifically, the sub CPU 71 determines whether or not the game / operation state information (sub) indicates that it is in the AT operation state. At this time, when determining that the sub CPU 71 is in the AT operating state, the sub CPU 71 selects the AT operating state effect selection table (see FIG. 12B) (step S253), and proceeds to the processing of step S254. On the other hand, when determining that the sub CPU 71 is not in the AT operating state, the sub CPU 71 then determines whether or not it is in the BB operating state (step S242). Specifically, the sub CPU 71 determines whether or not the game / operation state information (sub) indicates the BB operation state.

  When the sub CPU 71 determines in the process of step S242 that it is in the BB operating state, the sub CPU 71 selects an effect selection table for BB operating state (not shown) (step S252), and proceeds to the process of step S254. On the other hand, when the sub CPU 71 determines that it is not in the BB operating state, it then determines whether or not it is in the MB gaming state (step S243). Specifically, the sub CPU 71 determines whether or not the game / operation state information (sub) indicates the MB operation state.

  When the sub CPU 71 determines that it is in the MB gaming state in the process of step S243, it selects an MB gaming state effect selection table (not shown) (step S251), and proceeds to the process of step S254. On the other hand, when the sub CPU 71 determines that it is not in the MB gaming state, it then determines whether or not it is in the internal winning state (step S244). Specifically, the sub CPU 71 determines whether or not the internal winning state information (sub) held in the sub control circuit 70 indicates the internal winning state. Note that the internal winning state means a BB carryover state or an MB carryover state.

  When the sub CPU 71 determines in the process of step S244 that it is in the internal winning state, the sub CPU 71 proceeds to the process of step S248. On the other hand, when the sub CPU 71 determines that the internal winning state is not established, the sub CPU 71 then determines whether BB1, BB2 or MB is included in the internal winning combination (step S245).

  When the sub CPU 71 determines that the internal winning combination does not include BB1, BB2, or MB in the process of step S245, the sub CPU 71 proceeds to the process of step S250. On the other hand, when determining that the internal winning combination includes BB1, BB2, or MB, the sub CPU 71 changes the internal winning state information (sub) held in the sub control circuit 70 to the internal winning state (step S246). . Next, the sub CPU 71 performs a BB winning number counter update process (step S247). Specifically, the sub CPU 71 adds “1” to the value of the BB winning number counter when BB1 or BB2 is determined as the internal winning combination.

  Next, when the sub CPU 71 determines that it is in the internal winning state in the processing of step S244, or after performing the processing of step S247, the internal winning combination includes a role other than BB1, BB2, or MB. It is discriminated whether or not (step S248). At this time, if the sub CPU 71 determines that the winning combination other than BB1, BB2, or MB is not included in the internal winning combination, the process proceeds to step S250. On the other hand, when determining that the internal winning combination includes a combination other than BB1, BB2, or MB, the sub CPU 71 masks the bits corresponding to BB1, BB2, and MB (step S249). Specifically, the sub CPU 71 sets BB1, BB2, or MB in which “1” is set in an area (information similar to the internal winning combination storing area of the main control circuit 60) indicating information on the internal winning combination on the SDRAM 73. “0” is set to the bit corresponding to. When the sub CPU 71 completes the process of step S248, the sub CPU 71 proceeds to the process of step S249.

  Next, when the sub CPU 71 determines that the internal winning combination does not include BB1, BB2, or MB in the process of step S245, the internal winning combination includes a role other than BB1, BB2, or MB in the process of step S248. When it is determined that it is not, or after performing the process of step S249, the general game state effect selection table is selected (step S250), and the process proceeds to step S254.

  Next, the sub CPU 71 determines the effect contents based on the effect selection table selected in the process of step S250, step S251, step S252, or step S253 and the random value acquired in advance (step S254).

  Next, the sub CPU 71 sets effect data based on the effect content determined in the process of step S254 (step S255).

  Next, the sub CPU 71 performs an AT game number counter update process, which will be described later with reference to FIG. 28 (step S256), and ends the effect lottery process.

  When the sub CPU 71 finishes the effect lottery process, the sub CPU 71 proceeds to the process of step S215 of the effect registration process (see FIG. 25) via the effect content determination process (see FIG. 26).

  Next, the AT game number counter update process by the sub CPU 71 will be described with reference to FIG. FIG. 28 is a diagram showing a flowchart of AT game number counter update processing by the sub CPU 71 of the present embodiment.

  First, the sub CPU 71 determines whether or not the selected effect number is any one of “11” to “13” (step S401). That is, the sub CPU 71 determines whether or not the selected effect content is any one of “Cherry 1 notification effect”, “Cherry 2 notification effect”, or “Cherry 3 notification effect”. At this time, when the sub CPU 71 determines that the selected effect number is not any of “11” to “13”, the AT game number counter updating process is terminated. On the other hand, when the sub CPU 71 determines that the selected effect number is any one of “11” to “13”, it subtracts “1” from the value of the AT game number counter (step S402).

  Next, the sub CPU 71 determines whether or not the value of the AT game number counter is “0” (step S403). At this time, when the sub CPU 71 determines that the value of the AT game number counter is not “0”, the sub CPU 71 ends the AT game number counter update process. On the other hand, when the sub CPU 71 determines that the value of the AT game number counter is “0”, the sub CPU 71 then changes the game / operation state information (sub) held in the sub control circuit 70 to the general game state (step). S404), the AT game number counter update process is terminated.

  When the sub CPU 71 finishes the AT game number counter update process, the process of step S215 of the effect registration process (see FIG. 25) through the effect lottery process (see FIG. 27) and the effect content determination process (see FIG. 26). Migrate to

  Next, with reference to FIG. 29, a display command reception process by the sub CPU 71 will be described. FIG. 29 is a diagram showing a flowchart of processing at the time of display command reception by the sub CPU 71 of this embodiment.

  First, the sub CPU 71 adds “1” to the value of the game number counter (step S261).

  Next, the sub CPU 71 determines whether or not the display combination is a watermelon (step S262). At this time, when the sub CPU 71 determines that the display combination is not a watermelon, the process proceeds to the process of step S269. On the other hand, when determining that the display combination is watermelon, the sub CPU 71 then determines whether or not it is a general gaming state or an AT operating state (step S263). Specifically, the sub CPU 71 determines whether or not the game / operation state information (sub) indicates a general game state or an AT operation state.

  When the sub CPU 71 determines that it is not the general gaming state or the AT operating state in the process of step S263, it sets the effect data based on the display combination or the like (step S277), and ends the display command receiving process. On the other hand, when the sub CPU 71 determines that the game state is the general gaming state or the AT operation state, the sub CPU 71 then calculates the BB winning rate α based on the values of the BB winning number counter and the gaming number counter (step S264).

  Next, the sub CPU 71 selects an AT operation lottery table (see FIG. 13) according to the set value, and performs an AT operation lottery based on the random value and the lottery value corresponding to the BB winning rate α calculated in the process of step S264. This is performed (step S265).

  Next, the sub CPU 71 determines whether or not the result of the AT operation lottery in the process of step S265 is a win (step S266). At this time, when the sub CPU 71 determines that the result of the AT operation lottery is not winning, the effect data is set based on the display combination or the like (step S277), and the display command reception process is terminated. On the other hand, when the sub CPU 71 determines that the result of the AT operation lottery is winning, the sub CPU 71 then selects the AT number lottery table (see FIG. 14) according to the set value, and calculates the random number value and the processing in step S264. The number-of-AT lottery based on the lottery value corresponding to the BB winning rate α is performed (step S267).

  Next, the sub CPU 71 adds the AT number determined by the AT number lottery in the process of step S267 to the value of the AT number counter (step S268), and then sets effect data based on the display combination and the like (step S268). S277), the display command reception process is terminated.

  On the other hand, when the sub CPU 71 determines that the display combination is not a watermelon in the process of step S262, the sub CPU 71 then determines whether or not it is a general gaming state (step S269). Specifically, the sub CPU 71 determines whether or not the game / operation state information (sub) indicates a general game state. At this time, when the sub CPU 71 determines that the game state is not in the general gaming state, the effect data is set based on the display combination or the like (step S277), and the display command reception process is terminated. On the other hand, when the sub CPU 71 determines that it is in the general gaming state, it then determines whether or not the display combination is a bell (step S270).

  When the sub CPU 71 determines in the process of step S270 that the display combination is not a bell, the sub CPU 71 sets effect data based on the display combination or the like (step S277), and ends the display command reception process. On the other hand, when determining that the display combination is a bell, the sub CPU 71 determines whether or not the value of the AT number counter is “1” or more (step S271).

  When the sub CPU 71 determines that the value of the AT number counter is not equal to or greater than “1” in the process of step S271, the sub CPU 71 sets effect data based on the display combination or the like (step S277), and ends the display command reception process. . On the other hand, if the sub CPU 71 determines that the value of the AT number counter is “1” or more, then, the sub CPU 71 calculates the BB winning rate α based on the values of the BB winning number counter and the game number counter (step S272). .

  Next, the sub CPU 71 selects the AT game number lottery table (see FIG. 15) according to the set value, and the AT game number based on the random number and the lottery value corresponding to the BB winning rate α calculated in the process of step S272. A lottery is performed (step S273).

  Next, the sub CPU 71 adds the AT game number determined by the AT game number lottery in the process of step S273 to the value of the AT game number counter (step S274), and then the game / operation held in the sub control circuit 70 The state information (sub) is changed to the AT operation state (step S275).

  Next, the sub CPU 71 subtracts the value of the AT number counter or “1” (step S276), then sets the effect data based on the display combination or the like (step S277), and ends the display command reception process. .

  When the sub CPU 71 finishes the process at the time of display command reception, the sub CPU 71 shifts to the process of step S215 of the effect registration process (see FIG. 25) through the effect content determination process (see FIG. 26).

  In the gaming machine 1 described above, the sub CPU 71 counts the number of games in which a game has been performed, counts the number of BB wins determined by BB1 or BB2 as an internal winning combination, and counts the number of games and the number of BB wins. Based on the above, the BB winning rate α is calculated, the liquid crystal display device 5 displays an auxiliary image for establishing the internal winning combination, and the control ROM 72 causes the liquid crystal display device 5 to display the auxiliary image. In order to determine whether or not to operate the AT operation lottery, an AT operation lottery table that defines the lottery value indicating the probability of operating the AT operation state for each range in which the BB winning rate α is divided is stored. The sub CPU 71 determines whether or not to operate the AT operation state based on the BB winning rate α and the AT operation lottery table by the AT operation lottery. To operate the T operating state. At this time, in the AT operation lottery table, the range and lottery value in which the level of the BB winning rate α is divided so that the winning probability based on the lottery value increases as the range in which the level of the BB winning rate α is divided becomes low. Are defined in association with each other.

  Therefore, according to the gaming machine 1, when the BB winning rate α is low, the probability that the AT operating state is activated is high, whereas when the BB winning rate α is high, the probability that the AT operating state is activated is low. Therefore, the difference between the total number of inserted medals and the total number of paid-out medals does not increase, so that the player can be rescued and the player's irritability can be prevented.

  In addition, in the gaming machine 1, since the control ROM 72 determines the number of ATs to activate the AT operation state from among 1, 3, and 5 by lottery, 1 time, 3 times, and 5 times are determined respectively. The AT number lottery table that defines the lottery value indicating the probability of being played is determined for each range in which the level of the BB winning rate α is divided, and the sub CPU 71 determines the AT number based on the BB winning rate α and the AT number lottery table. Is determined by lottery. At this time, the AT number lottery table classifies the level of the BB winning rate α so that the expected value of the AT number obtained based on the lottery value becomes higher as the range in which the level of the BB winning rate α is classified becomes lower. The determined range is associated with the lottery value.

  Therefore, according to the gaming machine 1, when the BB winning rate α is low, the probability that a large number of ATs is determined increases. On the other hand, when the BB winning rate α is high, the AT number is small. Since the probability of being decided increases, the difference between the total number of medals inserted and the total number of medals paid out does not increase, and it is possible to rescue the player and prevent the player from being irritated it can.

  Further, since the control ROM 72 determines the number of AT games that can be played in the AT operating state by lottery from the 10 games, 20 games, and 30 games, the gaming machine 1 has 10 games, 20 games, and 30 games. An AT game number lottery table that defines lottery values indicating the respective probabilities determined for each range in which the BB winning rate α is divided is stored, and the sub CPU 71 stores the BB winning rate α and the AT game number lottery table. Based on the number of AT games based on the lottery. At this time, the AT game number lottery table increases or decreases the BB winning rate α so that the expected value of the AT game number obtained based on the lottery value becomes higher as the range in which the BB winning rate α is divided becomes lower. The range and the lottery value are defined in association with each other.

  Therefore, according to the gaming machine 1, when the BB winning rate α is low, the probability that a large number of games are determined as the number of AT games is high. On the other hand, when the BB winning rate α is high, the number of AT games is as follows. Since the probability that a small number of games will be determined increases, the difference between the total number of inserted medals and the total number of paid out medals does not increase, so that the player can be rescued and the player's eagerness is struck Can be prevented.

  Furthermore, the gaming machine 1 is used when the set value change switch 200S changes the set value, and the ROM 32 has a plurality of internal lotteries having different winning ranges corresponding to BB1 or BB2 for each set value. The table is stored, and the main CPU 31 selects an internal lottery table according to the set value and determines an internal winning combination based on the selected internal lottery table. In addition, the control ROM 72 stores an AT operation lottery table having different ranges in which the level of the BB winning rate α is divided for each set value, and the sub CPU 71 stores the BB winning rate α, the set value, and the AT operation lottery table. Whether or not to activate the AT operation state is determined by lottery.

  Therefore, according to the gaming machine 1, since the range in which the level of the BB winning rate α in the AT operation lottery table is divided for each set value is different, the change in the BB winning rate α due to the change of the set value is appropriately set. Can respond.

  Furthermore, the gaming machine 1 is used when the set value change switch 200S changes the set value, and the ROM 32 has a plurality of internal lotteries having different winning ranges corresponding to BB1 or BB2 for each set value. The table is stored, and the main CPU 31 selects an internal lottery table according to the set value and determines an internal winning combination based on the selected internal lottery table. Further, the control ROM 72 stores an AT number lottery table in which the range in which the BB winning rate α is divided is different for each set value, and the sub CPU 71 stores the BB winning rate α, the set value, and the AT number lottery table. Based on the above, the number of ATs is determined by lottery.

  Therefore, according to the gaming machine 1, the range in which the level of the BB winning rate α in the AT number lottery table is divided for each set value is different, so that the change in the BB winning rate α due to the change of the set value is appropriately determined. Can respond.

  Furthermore, the gaming machine 1 is used when the set value change switch 200S changes the set value, and the ROM 32 has a plurality of internal lotteries having different winning ranges corresponding to BB1 or BB2 for each set value. The table is stored, and the main CPU 31 selects an internal lottery table according to the set value and determines an internal winning combination based on the selected internal lottery table. Further, the control ROM 72 stores an AT game number lottery table in which the range in which the BB winning rate α is divided is different for each set value, and the sub CPU 71 stores the BB winning rate α, the set value, and the AT game number lottery. The number of AT games is determined by lottery based on the table.

  Therefore, according to the gaming machine 1, since the range in which the level of the BB winning rate α in the AT game lottery table is divided for each set value is different, the change of the BB winning rate α due to the change of the set value is also caused. Appropriate measures can be taken.

  In the present embodiment, in calculating the BB winning rate α, the number of games since the power of the gaming machine 1 is turned on is counted by the number-of-games counter, but the starting time for counting the number of games is set appropriately. May be.
