A start switch, a stop switch for individually stopping the rotation of the reel, and a reel for performing stop control of the reel based on at least a lottery result of the lottery means A game machine comprising stop control means and winning determination means for determining a winning based on whether or not the combination of the pictures displayed by the reel at the time of stopping is a predetermined combination of pictures. And a mode setting means for setting a game mode for a normal game including a probability change mode, wherein the winning combination starts with a first winning combination for starting a first special game by winning, To initiate a more once the second special game of, and only one possible winning in the probability variation mode, or first in the probability variation mode has been set high probability of the internal winning than other of said game mode And the lottery means performs a lottery of whether or not the internal winning of the first winning combination is successful in the second special game in addition to the normal game. When the internal winning is made for the first winning combination, the internal winning is carried over until the first winning combination is won, while when the internal winning is made for the first winning combination during the second special game, If the first winning combination is not won in the game, the internal winning is lost, and the mode setting means sets the probability changing mode immediately after the end of the first special game, and the first time in the probability changing mode. of If you the internal winning award combination, if the second non-special play in the said exit probability variation mode, if it is the second in the special game is provided gaming table, characterized in that no exit the probability variation mode Is done.

In this gaming machine, when the probability change mode is set, it becomes possible to win the second winning combination or it is easy to win. In addition to this, in the second special game, the first winning game The internal winning lottery of the winning combination is performed and the winning is possible. In other words, when winning the second winning combination, the player is given an opportunity to win the first winning combination and enjoy the first special game. Can be made. In addition, since the chance to win the first winning combination at the time of the second special game is limited to the game that has been won internally, a game with a sense of tension can be realized. Furthermore, if the first winning combination is won at the time of the second special game, the game mode after the first special game becomes the probability change mode, and the situation advantageous to the player will continue. Can be further improved.

  In the present invention, the probability of the internal winning of the first winning combination may be set higher in the second special game than in the normal game. According to this configuration, the pleasure of the probability change period can be further improved.

  Also, in the present invention, the mode setting means terminates the probability changing mode when the first winning combination is won in the probability changing mode, and ends the first winning combination in the second special game. When winning, the probability variation mode can be set in the normal game after the end of the first special game. According to this configuration, if the first winning combination is won during the second special game, the probability variation mode is continued, so that the player can detect whether or not the probability variation period continues. At the same time, the joy of the probability change period can be further improved.

  In addition, the second special game can be ended in one game. A game with a sense of tension can be realized by ending the second special game in one game.

  The first special game may be a bonus game such as a big bonus game or a regular bonus game, and the second special game may be an accessory game.

  As described above, according to the present invention, the joy of the probability change period can be further improved.

Next, the circuit configuration of the control unit of the slot machine 100 will be described in detail with reference to FIGS. The slot machine 100 includes a main control unit 300 that controls the central part of the game, and a sub control unit 400 that controls various devices according to signals transmitted from the main control unit 300.

<Main control unit>
First, the main control unit 300 of the slot machine 100 will be described with reference to FIG. The main control unit 300 includes a CPU 310 that is an arithmetic processing unit for controlling the entire main control unit 300, a data bus and an address bus for the CPU 310 to transmit and receive signals to and from each IC and each circuit, It has the structure described below. The clock correction circuit 314 is a circuit that divides the clock oscillated from the crystal oscillator 311 and supplies it to the CPU 310. For example, when the frequency of the crystal oscillator 311 is 12 MHz, the divided clock is 6 MHz. The CPU 310 operates by receiving the clock divided by the clock circuit 314 as a system clock.

  The CPU 310 is connected to a timer circuit 315 for setting a monitoring cycle for constantly monitoring the state of sensors and switches, which will be described later, and a transmission cycle of a driving pulse of a motor for rotating the reel, via a bus. Yes. When the power is turned on, the CPU 310 transmits the frequency dividing data stored in the predetermined area of the ROM 312 to the timer circuit 315 via the data bus. The timer circuit 315 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 310 at each interrupt time. In response to this interrupt request, the CPU 310 executes monitoring of each sensor and transmission of drive pulses. For example, when the system clock of the CPU 310 is set to 6 MHz, the frequency division value of the timer circuit 315 is set to 1/256, and the data for frequency division of the ROM 312 is set to 44, the reference time for this interrupt is 256 × 44 ÷ 6 MHz = 1. 877 ms.

  Further, the CPU 310 stores a ROM 312 that stores various data such as a program for controlling each IC, lottery data used for internal winning lottery, reel stop control data, and temporary data. A RAM 313 is connected. Other storage means may be used for these ROM 312 and RAM 313, and this is the same in the sub-control unit 400 described later.

The stop button sensor 322 is installed in each of the stop buttons 137 to 139 and detects the operation of the stop button by the player. The medal insertion button sensor 323 is installed in each of the medal insertion buttons 130 and 131, and detects an insertion operation when a medal electronically stored in the RAM 313 is inserted as a game medal. The settlement button sensor 324 pays out a medal that can be settled when the settlement button 132 is pressed once. In this embodiment, the medals that can be settled are both the stored medals and the bet medals, but only the stored medals may be used. The medal payout sensor 326 is a sensor that detects the medals to be paid out one by one in order to count the medals paid out from the slot machine 100. Each of the above sensors may be a non-contact type sensor or a contact type sensor.

  The CPU 310 further has an input interface 361 and output interfaces 370 and 371 connected to an address bus via an address decoding circuit 350. The CPU 310 exchanges signals with external devices via these interfaces. An index sensor 325 is connected to the input interface 361. The index sensor 325 is installed at a predetermined position on the mounting base of each of the reels 110 to 112, and becomes H level each time the light shielding piece provided on the reel passes through the index sensor 325. When detecting this signal, the CPU 310 determines that the reel has made one rotation, and resets the rotational position information of the reel to zero. The output interface 370 includes a reel motor driving unit 330 for driving a stepping motor and the like for rotating the reel, and a hopper (a device for paying out medals accumulated in the bucket from the medal payout opening 155, not shown). ) And a game lamp 340 (specifically, a winning line display lamp 120, a start lamp 121, a replay lamp 122, an announcement lamp 123, a medal insertion lamp 124, etc.) 7 segment display 341 (payout number display 125, display 126, stored number display 127, etc.) is connected.

  A random number generation circuit 317 is connected to the CPU 310 via a data bus. The random number generation circuit 317 is an increment counter capable of incrementing a value within a certain range and outputting the count value to the CPU 310 based on a clock oscillated from the crystal oscillator 311 and the crystal oscillator 316, which will be described later. Used for various lottery processes, including internal lottery for winning positions. The random number generation circuit 317 in the present embodiment includes two random number counters. An output interface 371 for transmitting a command to the sub control unit 400 is connected to the data bus of the CPU 310.

<Sub control unit>
Next, the sub-control unit 400 of the slot machine 100 will be described with reference to FIG. The sub-control unit 400 is an arithmetic processing unit that controls the entire sub-control unit 400 based on a main control command or the like transmitted from the main control unit 300, and the CPU 410 transmits and receives signals to and from each IC and each circuit. It has a data bus and an address bus for performing, and has a configuration described below. The clock correction circuit 414 is a circuit that corrects the clock oscillated from the crystal oscillator 411 and supplies the corrected clock to the CPU 410 as a system clock. Further, a timer circuit 415 is connected to the CPU 410 via a bus. The CPU 410 transmits the frequency dividing data stored in the predetermined area of the ROM 412 to the timer circuit 415 via the data bus at a predetermined timing. The timer circuit 415 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 410 at each interrupt time. The CPU 410 controls each IC and each circuit based on the interrupt request timing.

  In addition, the CPU 410 temporarily stores a ROM 412 in which commands and data for controlling the entire sub-control unit 400, backlight lighting patterns and data for controlling various displays, and the like are stored. The RAM 413 is connected via each bus. The CPU 410 is connected to an input / output interface 460 for transmitting and receiving external signals. The input / output interface 460 includes a backlight 420 for illuminating the picture of each reel 110 to 112 from the back, a front surface. A door sensor 421 for detecting opening / closing of the door 102 and a reset switch 422 for clearing data in the RAM 413 are connected.

  An input interface 461 for receiving a main control command from the main control unit 300 is connected to the CPU 410 via a data bus, and an effect process that excites the entire game based on the command received via the input interface 461. Etc. are executed. A sound source IC 480 is connected to the data bus and address bus of the CPU 410. The sound source IC 480 controls sound according to a command from the CPU 410. The sound source IC 480 is connected to a ROM 481 that stores sound data. The sound source IC 480 amplifies the sound data acquired from the ROM 481 by the amplifier 482 and outputs the sound data from the speaker 483.

Further, a demultiplexer 419 is connected to the output interface 470. The demultiplexer 419 distributes the signal transmitted from the output interface 470 to each display unit and the like. That is, the demultiplexer 419 controls the upper lamp 150, the side lamp 151, the center lamp 152, the waist lamp 153, the lower lamp 154, the reel panel lamp 128, and the tray lamp 210 according to the data received from the CPU 410. CPU 410 performs signal transmission to rendering device control unit 500 via demultiplexer 419. The rendering device control unit 500 controls the rendering device 600.

<Pattern arrangement>
FIG. 4 is a diagram in which a pattern arrangement applied to each of the reels 110 to 112 is developed in a planar manner. As shown in the figure, each reel 110 to 112 has a plurality of types of patterns arranged in a predetermined number of frames (21 frames in this case). In addition, in the same figure, although each picture is simplified and shown by the character, in the case of various designs, for example, “watermelon”, a picture or the like imitating a watermelon is drawn. Note that the pattern arrangement numbers 0 to 20 shown at the left end of the figure are numbers indicating the arrangement positions of the patterns on the reels 110 to 112. For example, a cherry pattern is arranged on the number 0 frame of the left reel 110, and a tiger pattern is arranged on the number 0 frame of the right reel 112.

<Type of winning prize>
The kind of winning combination can be arbitrarily adopted, but the following winning combination is adopted in the present embodiment. 5 (a) to 5 (c) show the game modes (A to C) during normal game.
FIG. 5A is a diagram showing the types of winning combinations, the corresponding pattern combinations, the number of medals to be paid out at the time of winning, the winning probability of internal lottery, and the contents of the corresponding reel control data. ) Is mode A, FIG. 5B shows mode B, and FIG. 5C shows mode C. In FIG. 5, for convenience of explanation, “no win” is included in the winning combination, but this is not a winning combination but merely a loss.

・ Big Bonus (BB):
This is a winning combination in which a big bonus game (BB game / first special game) is started by winning. BB is an object of internal lottery not only in a normal game (mode A) but also in a single bonus game described later. Also, in this embodiment, the flag is carried over if the BB is internally won in the normal game (mode A), that is, the BB internal winning is carried over until winning the BB, but if the BB is internally won in the single bonus game If the flag is not carried over and BB is not won in the game, the internal winning of BB will disappear.
・ Single Bonus (SB):
This is a winning combination in which a single bonus game (SB game / second special game) is started by winning. As described above, in this embodiment, BB is also subject to internal lottery in the SB game, and the probability of internal winning is set higher than that in the normal game (mode A) (see FIGS. 5A and 5D). .)
・ Small role:
A winning combination in which a predetermined number of medals are paid out by winning, and in the case of this embodiment, there are three types: watermelon, bell, and cherry. Corresponding pattern combinations and the number of payouts are as shown in FIG. For cherry, the pattern of the middle reel 111 and the right reel 112 is not questioned.
・ Replay (replay):
The winning combination is a winning combination in which a game can be performed without inserting medals in the next game, and medals are not paid out. In the case of the present embodiment, the corresponding pattern combination is “replay-replay-replay”.

Next, FIG. 5D shows the type of winning combination at the time of the SB game, the corresponding pattern combination, the number of medals paid out at the time of winning, the winning probability of the internal lottery, the contents of the corresponding reel control data, FIG.
・ Functions:
This is a winning combination in which a predetermined number (15 in this case) of medals is paid out by winning.

Next, although not shown in FIG. 5, there are the following winning combinations.
・ Shift regular bonus (SRB)
This is a winning combination that wins only during the BB game (more specifically, during the BB general game), and is a winning combination in which a shift regular bonus game (SRB game) is started by winning. In the present embodiment, the winning combination in the SRB game is an accessory.

  An internal winning probability is set for each winning combination for each set value (for example, 1 to 6) (the internal winning probability in FIG. 5 is an example). However, the winning probabilities may be the same between the set values. In the figure, the winning probability is shown, but the actual internal lottery process is as follows. In other words, the range of random values (0 to 65535) acquired at the time of winning combination internal lottery is divided in advance into several areas (areas corresponding to the size of each winning probability). Winning and loss are associated. These pieces of information are stored in the ROM 312 as a winning combination lottery table for each gaming state and each gaming mode. In the internal drawing of the winning combination, the internal winning combination of the winning combination is determined according to which range the obtained random number value belongs. The result is decided. When the winning combination is won internally, the corresponding internal winning flag is turned ON. The internal winning flag is set in a predetermined area on the RAM 313, and is turned OFF when the game ends, except when the flag is to be carried over.

<Reel stop control>
Next, stop control of the reels 110 to 112 will be described. The reel stop control is performed based on the selected reel stop control data by selecting one of a plurality of predetermined reel stop control data based on the internal lottery result, the game state, and the game mode. In this embodiment, so-called pull-in control (frame slip control) is performed. The reel stop control data is stored in the ROM 312 of the main control unit 300.

  5 (a) to 5 (d) show the respective winning combinations in the case of each game mode (FIG. 5 (a) to (c)) and the SB game (FIG. 5 (d)). The “name”, “control content”, and “selection probability” of the reel stop control data when winning or not winning are shown. In addition to this, reel stop control data for the SRB game and the BB game are also prepared, but are omitted here.

  In the figure, “name” is given for convenience of explanation of the present embodiment, and in actuality, a unique identifier is set for each data to identify each reel stop control data. “Control content” indicates the content of the reel stop control executed when the reel stop control data is selected. Among these, what is indicated as “... Aligned” indicates reel stop control data that allows a predetermined pattern combination to be displayed in alignment on the winning line 114.

  However, since it is only “permitted”, if the timing of operating each of the stop buttons 137 to 139 is bad, the corresponding pattern combination may not be prepared. However, there is a case in which 100% is arranged depending on the arrangement of the patterns on the reels 110 to 112 and the number of drawn frames. In the case of this embodiment, it is assumed that the reel stop control data of “name” of SB-A, bell A, replay A, replay C, and accessory-A has 100% corresponding pattern combinations.

  “Lose” means that control is performed so that there is no pattern combination corresponding to the winning combination regardless of the timing of operating each of the stop buttons 137 to 139. “Selection probability” indicates the probability of which reel stop control data is selected by lottery when a plurality of reel stop control data are associated with one winning combination.

<Game state>
In the present embodiment, the game state includes a normal game, a BB game (specifically, a BB general game), an SRB game, and an SB game. Information on the currently set gaming state is stored in a predetermined area on the RAM 313.
・ BB game:
Although the content of the BB game can be considered in plural types, in this embodiment, it is possible to win the SRB during the BB game, and when this is won, the SRB game is started. The BB game is referred to as a BB general game in order to distinguish between a case where an SRB game is being played and a case where it is not. Although there are a plurality of BB game end conditions, in the present embodiment, the SRB winning count reaches a predetermined number (here, 3 times) or the BB general game count reaches a predetermined number ( The BB game is finished 30 times here. The number of games for the BB general game and the number of SRB winnings are managed by a “BB general game number counter” and an “SRB winning number counter” set in predetermined areas on the RAM 313, respectively. In this embodiment, a big bonus game is adopted as the first special game, but a regular bonus may be used. A plurality of types of contents of the regular bonus game can be considered, but the contents can be the same as those of the SRB game.
・ SRB game:
A plurality of types of SRB games can be considered. In the case of this embodiment, a predetermined number of times (in this embodiment, 12 times) of a game (referred to as an accessory game) is consumed, or an accessory is determined in advance. The process ends when any of the conditions of winning the number of times (8 times in the present embodiment) is satisfied. The number of SRB games and the number of winnings of the winning combination are managed by the “SRB gaming number counter” and the “Hobby winning number counter” which are set in predetermined areas on the RAM 313, respectively.
・ SB game:
Although there are a plurality of types of contents of the SB game, in the present embodiment, the game ends when a predetermined number of games (one game in the present embodiment) are consumed. In other words, it is a game in which an accessory game can be played only once.

<Game mode>
In the present embodiment, one of the following three game modes is set during a normal game. Information on the currently set game mode is stored in a predetermined area on the RAM 313.
・ Mode A (Probability mode)
In this mode, SB is a target of internal lottery, and SB can be won. When the SB is won, the SB game is started. In the present embodiment, as described above, the BB is also subject to the internal lottery even in the SB game, and the BB can be won. Since SB wins internally with a probability of 1/40 (see FIG. 5 (a)), it is possible to win with a relatively high probability, which works for the player itself, but as described above, in the SB game, BB In this embodiment, the BB internal winning probability is set higher in the SB game than in the normal game (mode A) (see FIGS. 5A and 5D). ), It is easy to win BB, and it is a mode that works extremely advantageous to the player.

  Mode A is set immediately after the end of the BB game, and ends when the BB is won internally, and the mode B is entered. In other words, when BB is won internally in mode A, mode A ends, but when SB is won during mode A, and when BB is won during SB game, the normal game after the end is mode A. A will be continued, and a state advantageous to the player will continue.

・ Mode B (Hamari mode)
BB and SB are not eligible for internal lottery. Therefore, no SB is won. In the present embodiment, in mode B, the internal winning of BB remains due to flag carryover, but a very low probability (1/65536; 1/65536, when “BB-A” reel stop control data is selected). See) only to win the BB. Therefore, it becomes a hamari mode that hardly wins the BB. Note that it may not be possible to win BB at all. Mode B is set by internally winning BB in mode A, and ends when the reel stop control data of “Replay C” is selected and a predetermined pattern combination (Bell-Bell-Tiger) is displayed. Transition to mode C. Mode B also ends when a predetermined number of games has been consumed. The number of games is managed by a “mode B game number counter” set in a predetermined area on the RAM 313.

・ Mode C (Hamari end mode)
BB and SB are not eligible for internal lottery. Therefore, no SB is won. In the present embodiment, in mode C, the internal winning of BB remains due to carry-over of the flag subsequent to mode B, and the reel stop control data of “BB-A” is selected, and an extremely high probability (1 / 1.28. FIG. 5). (See (c).) BB will be won. That is, the mode C is a mode for ending the maritime (mode B). In the case of mode B and mode C, the internal winning probability of replay is significantly different (the former is 1 / 1.09, the latter is 1 / 7.30. FIGS. 5B and 5C). In the case of mode B, due to reel stop control, the actual replay winning probability is approximately 1 / 7.30 (internal winning probability: 1 / 1.09 × replay A selection probability: 1/6. 69 (see FIG. 5 (b)), which is substantially the same as the winning probability in the case of mode C, whether mode B is set or mode C is set depending on the replay winning frequency. So that the player cannot distinguish.

<Outline of the game>
FIG. 13 is a diagram showing an outline of the game in the present embodiment. When the mode A is set in the normal game, since the mode A is a probability change mode in which the SB can be won with a relatively high probability, the SB is frequently won and the SB game can be performed. Then, when winning the BB in the SB game, the BB game is performed, and the mode A is set again in the normal game after the end of the BB game. For this reason, the state where a player can obtain profits continues. However, if BB is won internally in mode A of the normal game, the mode B is set as the game mode, and it is not possible to win SB, and it is not possible to substantially win BB. Will continue to be in a disadvantageous situation.

  In mode B, when the bell-bell-tigers are displayed together or when a predetermined number of games have been consumed, mode B ends and mode C is set. Here, the player can win the BB, and when winning the BB, the BB game is played. In the normal game after the end of the BB game, the mode A is set and a chance is given to the player. Thereafter, the game state and the game mode are similarly switched and the game proceeds.

  As described above, in the present embodiment, when mode A is set, whether or not SB can be won is determined. In addition, in the SB game, an internal lottery of the BB winning combination is performed and winning can be made. That is, when winning the SB, the player is given an opportunity to win the BB and enjoy the BB game, and the joy of the probability change period can be further improved. Further, since the probability of BB internal winning is set higher in the SB game than in the normal game, the joy of the probability change period can be further improved.

  In addition, if the BB is won during the SB game, the mode A is continued, so that the player can detect whether or not the probability variation period continues and can further improve the pleasure of the probability variation period. . In addition, since the SB game ends with one game, a game with a sense of tension can be realized.

<Basic control of games>
FIG. 6A is a flowchart showing the basic control of the game in the slot machine 100 of the present embodiment. Basic control of the game is performed mainly by the Main CPU 310, and the processing shown in FIG. Hereinafter, this process will be described. When the power is turned on, first, initial processing is executed in S1. Details of the initial processing will be described later. In S2, processing related to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted. It is not necessary to insert a medal when winning the re-game in the previous game.

  In S3, processing related to acceptance of a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is determined, and in the subsequent S4, an effective winning line 114 is determined. In S5, the random number generated by the random number generator 311 is acquired. In S6, the winning combination lottery table stored in the ROM 312 is read according to the current gaming state and gaming mode, and the internal winning lottery of the winning combination is performed using this and the random value acquired in S5. As a result of the internal lottery, when any winning combination is won internally, the winning combination flag is turned ON. Further, the reel stop control data illustrated in FIG. 5 is selected based on the internal lottery result. In addition, the random value acquired in S5 is transmitted to the sub-control unit 400, and the sub-control unit 400 executes an effect lottery to determine the content of the game effect.

  In S7, rotation of all reels 110 to 112 is started. In S8, the stop buttons 137 to 139 can be received, and when any one of the stop buttons is pressed, any of the reels 110 to 112 corresponding to the pressed stop button is selected as the reel stop control data selected in S6. Stop based on. In S9, a winning determination is performed. Here, when a picture combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “watermelon-watermelon-watermelon” is arranged on the activated winning line 114, it is determined that the watermelon is won. In addition, the flag indicating the internal winning of each winning combination is reset. However, as described above, when BB is not won, the ON state is maintained in a predetermined case, and it is carried over to the next game transition. In S10, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out.

  In S11 to S14, processing relating to setting of the game mode is performed. Details will be described later. In S15, a flag disappearing process related to the internal winning flag of BB is performed. Details will be described later. In S16, game state control processing is performed. Details will be described later. As described above, one game is completed, and thereafter, the process proceeds by returning to S2 and repeating the above-described processing.

<Initial processing>
Next, the initial process of S1 will be described. FIG. 6B is a flowchart showing the initial processing of S1. In S21, various initialization processes of the main control unit 300 are performed. In S22, it is determined whether or not the setting of the internal winning probability of the winning combination has been changed. If applicable, the process proceeds to S23, and if not applicable, the process ends. In S23, processing for reflecting the setting change is performed. In S24, mode A is set as the game mode. Thus, the initial process ends. In the present embodiment, when the setting of the internal winning probability of the winning combination is changed, the mode A is set as the game mode.

<Mode setting process 1>
Next, the mode setting process 1 of S11 will be described. FIG. 7 is a flowchart showing the mode setting process 1 of S11. In S31, it is determined whether or not BB is won in the internal lottery (S6) of the current game. If applicable, the process proceeds to S32. If not applicable, the process ends. In S32, it is determined whether or not the current gaming state is an SB game. If applicable, the process ends. If not, the process proceeds to S33. In S33, mode B is set as the game mode. That is, this process is performed when BB is internally won in mode A. In S34, an initial value (1500 times here) of the number of games is set in the “mode B game number counter”. This initial value may be determined by lottery. In the mode B, the count value of the “mode B game number counter” is subtracted every time the game is consumed, and when the game becomes 0, the mode B ends. Therefore, the initial value is the number of mode B ceiling games. The process ends as described above.

<Mode setting process 2>
Next, the mode setting process 2 of S12 will be described. FIG. 8 is a flowchart showing the mode setting process 2 of S12. In S41, it is determined whether or not the end pattern combination (Bell-Bell-Tiger) in Mode B is displayed together in the current game. If applicable, the process proceeds to S42, and if not, the process proceeds to S43. In S42, mode C is set as the game mode. That is, mode B ends and mode C starts when the end pattern combination of mode B (bell-bell-tiger) is displayed. In S43, it is determined whether or not the current game mode is mode B. If applicable, the process proceeds to S44, and if not, the process ends. In S44, it is determined whether or not BB is won in this game. If applicable, the process proceeds to S45, and if not, the process ends. In S45, mode A is set as the game mode. In other words, in reality, there is almost no possibility, but when winning BB in mode B, mode A is set as the game mode of the normal game after the end of the BB game.

<Mode setting process 3>
Next, the mode setting process 3 in S13 will be described. FIG. 9 is a flowchart showing the mode setting process 3 in S13. In S51, it is determined whether or not the current game mode is mode C. If applicable, the process proceeds to S52, and if not applicable, the process ends. In S52, it is determined whether or not BB is won in this game. If applicable, the process proceeds to S53, and if not, the process ends. In S53, mode A is set as the game mode. That is, when winning the BB in the mode C, the mode A is set as the game mode of the normal game after the end of the BB game. The process ends as described above.

<Mode setting process 4>
Next, the mode setting process 4 in S14 will be described. FIG. 10 is a flowchart showing the mode setting process 4 in S14. In S61, it is determined whether or not the current game state is a normal game. If applicable, the process proceeds to S62, and if not, the process proceeds to S66. In S62, it is determined whether or not the current game mode is mode B. If applicable, the process proceeds to S63, and if not, the process proceeds to S66. In S63, the count value of the “mode B game number counter” is decremented by one. That is, it is management of the number of games in mode B. In S64, it is determined whether or not the count value of the “mode B game number counter” is zero. If applicable, the process proceeds to S65, and if not, the process proceeds to S66. In S65, mode C is set as the game mode. When this process is performed, the mode B ends when the predetermined number of games has been consumed.

  In S66, it is determined whether or not BB is won in this game. If applicable, the process proceeds to S67, and if not, the process proceeds to S67. In S67, the count value of the “mode B game number counter” is set to zero. The process ends as described above.

<Flag elimination process>
Next, the flag disappearance process in S15 will be described. FIG. 11 is a flowchart showing the flag disappearance process in S15. In S71, it is determined whether or not the current game mode is mode A. If applicable, the process proceeds to S72, and if not applicable, the process ends. In S72, it is determined whether or not the current gaming state is an SB game. If applicable, the process proceeds to S73, and if not applicable, the process ends. In S73, it is determined whether or not the BB internal winning flag is ON. If applicable, the process proceeds to S74, and if not applicable, the process ends. In S74, the internal winning flag of BB disappears. (Reset to OFF). As described above, when the BB is won internally during the SB game, the flag is not carried over. The process ends as described above.

  With this process, if the BB is won in the normal game, the internal win is carried over until the BB is won. If the BB is won in the SB game, the BB is not won if the game is not won. Winning will disappear. Therefore, the chance to win the BB at the time of the SB game is limited to the game that is won internally, so a game with a sense of tension can be realized.

<Game state control processing>
Next, the game state update process of S16 will be described. FIG. 12 is a flowchart showing the game state control process of S16. In S81, it is determined whether or not the SB is won in this game. If applicable, the process proceeds to S87, and if not, the process proceeds to S82. In S82, it is determined whether or not SRB has been won in this game. If applicable, the process proceeds to S88, and if not, the process proceeds to S83. In S83, it is determined whether or not BB is won in this game. If yes, go to S89, otherwise go to S84.

  In S84, it is determined whether or not the current gaming state is an SB game. If applicable, the process proceeds to S90, and if not, the process proceeds to S85. In S85, it is determined whether or not the current gaming state is an SRB game. If applicable, the process proceeds to S91, and if not, the process proceeds to S86. In S86, it is determined whether or not the current game state is a BB general game. If applicable, the process proceeds to S92, and if not applicable, the process ends. In S87, processing at the time of SB winning is performed. Here, the SB game is set as the gaming state. Also, the internal winning flag of SB is turned off. In S88, the process at the time of SRB winning is performed. Here, the SRB game is set as the gaming state. Also, the SRB internal winning flag is turned OFF. Furthermore, 12 times and 8 times are set as initial values of the “SRB game number counter” and the “object prize winning number counter”, respectively. Subtract one.

  In S89, a process for winning a BB is performed. Here, a BB game (BB general game) is set as the gaming state. Also, the internal winning flag of BB is turned OFF. Furthermore, 30 times and 3 times are set as initial values of the “BB general game number counter” and the “SRB winning number counter”, respectively. In S90, processing during the SB game is performed. Here, the normal game is set as the game state. In S91, processing during the SRB game is performed. Here, the count value of the “SRB game number counter” is decremented by one. In addition, when a prize is won in the game this time, the count value of the “prize winning number counter” is decremented by one. Furthermore, when either of the count values of the “SRB game number counter” and the “object winning prize counter” becomes 0, the BB general game is set as the game state. In S92, processing during BB general game is performed. Here, the count value of “BB general game number counter” is decremented by one. Further, when any of the count values of the “BB general game number counter” and the “SRB winning number counter” becomes 0, the normal game is set as the gaming state. The process ends as described above.

<Other embodiments>
In the above embodiment, the SB internal lottery is performed only in the mode A, and the SB winning is possible only in the normal game in which the mode A is set, but also in other game modes (at least one of the modes B and C). An internal lottery of SB can be performed to enable winning. In this case, in mode A, the probability of winning the SB is set higher than in other game modes, and it is easier to win SB in mode A, so that mode A is a probability change mode. There is no.

  Next, in the above-described embodiment, any one of modes A to C is set as the game mode in the normal game, but the configuration of the game mode is not limited to this. FIG. 14 is a schematic diagram of a game showing an example in which any of modes A to D is set as a game mode in a normal game.

  In the example of FIG. 14, mode D is prepared in addition to modes A to C described above. Then, the normal game after the end of the BB game is set to either mode A or mode D by lottery. Mode D is substantially the same as mode A except that SB cannot be won. That is, in mode D, SB cannot be won, so BB cannot be won, and when BB is internally won, the mode B is entered. In the example of FIG. 14, mode A is not always set as the game mode of the normal game after the end of the BB game, and mode A is not continued even if BB is won in the SB game. Accordingly, it is possible to give the player a thrilling feeling as to whether or not the mode A is continued at the end of the BB game.

  Next, FIG. 15 is a schematic diagram of a game showing an example in which one of modes A and B is set as a game mode in a normal game. That is, there is no mode C, and there are two types of game modes, mode A or mode B. Since there is no mode C, as soon as the mode B ends, the mode shifts to the mode A, which is advantageous to the player.

  Next, in the above embodiment, the game mode information is stored in a predetermined area on the RAM 313 to determine the current game mode. However, for the mode A, when the internal winning flag of the BB is turned on, the mode B is switched to. In order to shift, mode A is set when the internal winning flag of BB is OFF. Therefore, it can be determined whether or not the mode is A by turning ON / OFF the internal winning flag of BB. In particular, in the example of FIG. 15, since there are two types of game modes, mode A and B, it is possible to determine the current game mode by turning ON / OFF the internal winning flag of BB, and information on the game mode is stored on the RAM 313 in advance. There is no need to memorize the area.
