The functions of the game control means 100 are stored in advance in various processors (CPU, DSP, etc.), ASIC (gate array, etc.), ROM (an example of an information storage medium), or hardware such as RAM, ROM, etc. It is realized by software consisting of a given program.

  The game control means 100 includes an insertion acceptance means 105, a random number generation means 110, an internal lottery means 120, a main reel control means 130, a winning determination means 140, a payout control means 150, a replay processing means 160, a game state transition control means 170, Production control means 180 and storage means 190 are included.

  The insertion accepting means 105 accepts the insertion of medals for each game, and based on the insertion of three medals corresponding to the prescribed number of insertions, the first main reel MR1 for the start lever (rotation start operating means) SL. Processing for permitting the rotation start operation of the third main reel MR3 and the first sub reel SR1 to the third sub reel SR3 is performed.

  In the gaming machine of this embodiment, when a medal is inserted into the medal insertion slot MI, the insertion accepting unit 105 selects the inserted medals up to the specified number of insertions as the medal insertion switch 210 operates. Set to the input state. Further, in the gaming machine of the present embodiment, when the bet button B0 is pressed while the medal is credited to the gaming machine, the insertion accepting means 105 sets the specified number of insertions as the bet switch 220 is activated. Limit and set the credited medal to the inserted state.

  The random number generation means 110 is a means for generating random numbers for lottery. The random value can be generated based on, for example, a count value of an increment counter (a counter that counts numerical values so as to circulate a predetermined count range). In this embodiment, the “random number value” is not only a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, the acquisition timing and the like are irregular. Includes a value that can function as a random number.

  The internal lottery means 120 is a means for performing an internal lottery for determining whether or not a winning combination is made based on a start signal from a start switch 230 that is operated by a player pressing a start lever (rotation start operation means) SL. A lottery table selection process, a random number determination process, a lottery flag setting process, and the like are performed.

  In the lottery table selection process, it is determined which of the plurality of lottery tables stored in the lottery table storage unit 191 of the storage unit 190 is to be used for internal lottery. In the gaming machine according to the present embodiment, a plurality of types of game states, that is, a normal state, a big bonus establishment state (BB establishment state), and a big bonus state (BB state) can be set. As shown in FIG. 3, lottery tables A to C for internal lottery in each gaming state are stored. For example, when the gaming state is the normal state, the lottery table A is selected, when the gaming state is the BB establishment state, the lottery table B is selected, and when the gaming state is the BB state, A lottery table C is selected.

  In the lottery table A to the lottery table C, replay is performed for each of a plurality of random number values (for example, 65536 random number values of 0 to 65535). Any of various roles such as a small role (a role to which medals are paid out in accordance with winning a prize: a bell or a watermelon) and a big bonus (a role that triggers a transition to the BB state: BB) or a loss is associated.

  In the random number determination processing, a random number value (random number for lottery) is acquired from the random number generation unit 110 for each game based on a start signal input in accordance with the operation of the start switch 230, and lottery of the storage unit 190 is performed on the acquired random number value. It is determined whether or not the winning combination is won with reference to the lottery table stored in the table storage unit 191.

  In the lottery flag setting process, the lottery flag of the winning combination determined to be won based on the result of the random number determination process is changed from the non-winning state (first flag state, off state) to the winning state (second flag state, on Status). The lottery flag setting information is stored in the flag storage unit 192 of the storage unit 190. Also, in this embodiment, a lottery flag (carry-over possible flag) that can carry over the winning state for the next game until winning, and a non-winning state without carrying the winning state for the next game regardless of winning. A lottery flag (a carry-over impossible flag) to be reset is prepared. As a combination with which the former carry-over possible flag is associated, there is a big bonus (BB), and other combinations (for example, a small combination, replay) are associated with the latter carry-over impossible flag.

  The main reel control means 130 is based on the first main reel MR1 to the third main reel MR1 based on the start signal from the start switch 230 that is actuated by the player pressing the start lever (rotation start operation means) SL (rotation start operation). When the reel MR3 is rotationally driven by a step motor and the rotational speed of the first main reel MR1 to the third main reel MR3 reaches a predetermined speed (about 80 rpm: a rotational speed of about 80 revolutions per minute), a stop button Control is performed to permit the pressing operation (stop operation) of B1 to B3, and the first main reel MR1 to the third main reel MR3 that are rotationally driven by the step motor are set to the lottery flag setting state (internal lottery result). Control to stop accordingly.

  The main reel control unit 130 stops when the player presses the stop buttons B1 to B3 in a state where the pressing operation (stop operation) for the stop buttons (stop operation units) B1 to B3 is permitted (validated). When the switch 240 is actuated, the supply of drive pulses (motor drive signal) to the step motor of the main reel unit 310 is stopped based on the reel stop signal from the stop switch 240, whereby the first main reels MR <b> 1 to 3. Control is performed to stop each main reel of the main reel MR3.

  That is, the main reel control means 130 determines the stop position of the main reel corresponding to the pressed button of the first main reel MR1 to the third main reel MR3 each time each button of the stop buttons B1 to B3 is pressed. Thus, control is performed to stop the main reel at the determined stop position. Specifically, referring to the stop control table for the main reel stored in the first stop control table storage unit 193a of the storage unit 190, according to the pressing timing of the stop buttons B1 to B3, etc. (mode of stop operation) Further, the stop positions of the first main reel MR1 to the third main reel MR3 are determined, and control is performed to stop the first main reel MR1 to the third main reel MR3 at the determined stop position. In the gaming machine of the present embodiment, pressing the stop button B1 corresponds to a stop operation of the first main reel MR1, and pressing the stop button B2 corresponds to a stop operation of the second main reel MR2. Pressing the button B3 corresponds to a stop operation of the third main reel MR3.

  Here, in the stop control table for the main reel stored in the first stop control table storage means 193a, the first stop point at the time when the stop switch 240 is activated (when the pressing operation of each button of the stop buttons B1 to B3 is detected). Correspondence relationship between the position (press detection position) of the first main reel MR1 to the third main reel MR3 and the actual stop position (or the number of sliding symbols from the press detection position) of the first main reel MR1 to the third main reel MR3 Is set. In the present embodiment, a stop control table is provided for determining the stop positions of the first main reel MR1 to the third main reel MR3 according to the setting state of the lottery flag.

  In the gaming machine of the present embodiment, the main reel unit 310 includes a main reel index 315 made of a photosensor, and the main reel control means 130 is detected by the main reel index 315 every time the main reel rotates once. Based on the reference position signal, the current rotation state of the main reel is obtained by calculating the rotation angle (number of rotation steps of the rotation axis of the step motor) from the reference position of each main reel (the frame detected by the main reel index). Can be monitored. That is, the main reel control means 130 can obtain the position of the main reel when the stop switch 240 is operated by obtaining the rotation angle from the reference position of the main reel.

  Further, in the stop control table for main reels stored in the first stop control table storage unit 193a, when the lottery flags associated with two or more different combinations are set in the winning state, each combination The correspondence relationship between the position of each main reel at the time of operation of the stop switch 240 and the actual stop position of each main reel is set in accordance with the priority order defined in (1). In particular, in this embodiment, the priority order is determined in the order of “Replay> Big Bonus> Small”, and the main reel control means 130 has the lottery flags regarding two or more types of roles set to the internal winning state. In the case, according to the priority order set for each winning combination, the symbol constituting the winning form for the winning combination with higher priority is placed on the winning determination line in preference to the winning pattern for the winning combination with lower priority. Control to stop the main reel so as to display. When a lottery flag associated with two or more kinds of small roles is set to a winning state, priority is set according to a predetermined payout for each small role, and the higher the payout is, The priority order can be set higher.

  The main reel control means 130 performs so-called pull-in processing and kicking processing as control for stopping the main reel. The pull-in process is a control for stopping the main reel so that the symbol corresponding to the combination for which the lottery flag is set to the winning state stops on a valid winning determination line (so that the winning combination can be won). It is processing. On the other hand, the kicking process is the main reel so that the symbol corresponding to the combination for which the lottery flag is set to the non-winning state does not stop on the valid winning determination line (so that the winning combination cannot be won). Is a control process for stopping the process. That is, in the gaming machine of the present embodiment, the lottery flag setting state, the pressing timing of the stop buttons B1 to B3, the pressing order, the stop position of the main reel that has already stopped (display) The stop control table for the main reel is set so that the stop position of each main reel changes according to the symbol type). As described above, the main reel control means 130 can stop the symbol of the combination for which the lottery flag is set to the winning state in a winning form, while the symbol of the combination for which the lottery flag is set to the non-winning state is the winning type. Control is performed to stop the first main reel MR1 to the third main reel MR3 so as not to stop.

  In the gaming machine according to the present embodiment, the first main reel MR1 to the third main reel MR3 are rotating main reels corresponding to the pressed stop button within 190 ms from the time when the stop buttons B1 to B3 are pressed. The control state is set to stop That is, in the stop control table for determining the stop position of each rotating main reel, the number of frames required from when the stop buttons B1 to B3 are pressed until each main reel stops is in the range of 0 to 4 frames (predetermined The pull-in range is set. And the main reel control means 130 has a symbol corresponding to the winning combination in the internal lottery on the outer peripheral surface of the rotating main reel corresponding to the stop button that has been pressed among the stop buttons B1 to B3. When the stop button is pressed, the symbol corresponding to the winning combination is displayed when it is located within the range of 0 to 4 frames with respect to the display position (upper, middle, lower) on the winning determination line. Control is performed to stop the rotating main reel corresponding to the stop button for which the pressing operation has been performed so that the main reel is rotated so as to be displayed at the display position on the winning determination line.

  In the gaming machine of the present embodiment, according to the symbol arrangement of the first main reel MR1 to the third main reel MR3 shown in FIG. 4, a replay symbol “RP” arranged on the outer peripheral surface of each main reel, For the bell symbol “BL”, the symbols are arranged so that the interval is within 4 frames, and the replay symbol “RP” or the bell symbol “BL” regardless of the timing of pressing the stop buttons B1 to B3, the pressing order, etc. "Can be drawn into a display position on an arbitrary winning determination line.

  The winning determination means 140 performs a process of determining whether or not a winning combination has been won based on the stop mode of the first main reel MR1 to the third main reel MR3. Specifically, referring to the winning determination table stored in the winning determination table storage means 194 of the storage means 190, the winning determination line is displayed when all of the first main reel R1 to the third main reel R3 are stopped. It is determined whether or not the combination of symbols that are stopped at the time is a predetermined winning combination.

  In the present embodiment, as shown in FIG. 4, the replay symbol “RP”, the bell symbol “BL”, and the watermelon symbol are formed on the outer peripheral surfaces of the first reel R1 to the third reel R3 constituting the main reel unit 310. “WM”, BB symbol “blue 7”, and the like are arranged. As shown in FIG. 5, the combination of symbols displayed on the winning determination line when each reel is stopped can determine whether or not a big bonus (BB), replay, bell, or watermelon has been won. A winning determination table is prepared.

  In the gaming machine of this embodiment, when a winning combination is won based on the determination result of the winning determination means 140, a winning process is executed. As the winning process, a process for paying out medals, a replay process, a process for shifting a game state, and the like are executed. For example, when a small combination wins, the payout control means 150 performs a medal payout control process. When a replay wins, the replay processing means 160 performs a replay process, and when a big bonus is won. Processing for shifting the gaming state is performed by the gaming state transition control means 170.

  The payout control means 150 performs payout control processing relating to the payout of medals according to the game result. Specifically, when a small combination wins, the number of medals to be paid out in the game is set based on a predetermined payout for each combination, and the set number of medals to be paid out is set as a hopper unit 320 (payout device). The control which instruct | indicates is performed. When a plurality of small combinations wins in one game, the total payout of each winning small combination is set as the number of medals paid out in the game.

  The hopper unit 320 performs an operation of paying out medals of the payout number instructed by the payout control means 150. The hopper unit 320 is provided with a payout medal detection switch 325 that operates every time a medal is paid out. The payout control means 150 is actually operated from the hopper unit 320 based on an input signal from the payout medal detection switch 325. It is configured to be able to manage the number of medals paid out.

  If credits (internal storage) of medals are permitted, instead of actually paying out medals by the hopper unit 320, the number of credits stored in a credit storage area (not shown) of the storage unit 190 (not shown) A credit addition process for adding the number of payouts to the number of credited medals is performed to virtually pay out medals. As a result of the game, when a replay or a big bonus (BB) is won, as shown in FIG. 5, no payout is set for the replay and the big bonus. Although not performed, a process (0 sheet process) is performed in which formally 0 medals are paid out.

  When the replay is won, the replay processing means 160 performs a replay process (regame process) for setting the same preparation state as the previous game without requiring insertion of medals owned by the player for the next game. That is, in the gaming machine of this embodiment, when a replay is won, an automatic insertion is performed in which the same number of medals as the previous game are automatically inserted without using the player's own medals (including credit medals). Processing is performed, and the next game start operation (press operation of the start lever SL by the player) is waited with the same winning determination line as that of the previous game being validated.

  The gaming state transition control means 170 shifts the gaming state between the normal state, the big bonus state (BB state), and the big bonus state (BB state) based on the establishment of a predetermined transition condition. Perform control processing. As the game condition transition condition, one condition may be defined, or a plurality of conditions may be defined. In the case where a plurality of conditions are determined, the gaming state is determined based on the fact that one of the plurality of predetermined conditions is satisfied or all of the plurality of predetermined conditions are satisfied. It is possible to shift to another gaming state.

  The normal state is a game state corresponding to the initial state among a plurality of types of game states, and a transition from the normal state to the BB establishment state is possible. In the normal state, an internal lottery is performed with reference to a lottery table A in which BB is set as an internal lottery target.

  The BB establishment state is a gaming state that shifts when the BB is won in the internal lottery. In the BB establishment state, an internal lottery is performed with reference to the lottery table B in which BB is excluded from the internal lottery targets. In the BB establishment state, the lottery flag corresponding to BB is maintained in the winning state until BB wins.

  The BB state is a gaming state in which the symbol combination “blue 7, blue 7, blue 7” indicating the BB winning form is displayed on any of the winning determination lines L1 to L5 in the BB established state. . In the BB state, replay is excluded from the internal lottery targets, and an internal lottery is performed with reference to the lottery table C in which the winning probability of the bell is set higher than in the normal state. That is, in the BB state, it is easier to obtain more medals in a shorter period than in the normal state, and the gaming state is advantageous for the player. In the BB state, the BB state is terminated when the total number of medals paid out by the bonus game exceeds the maximum payout number (for example, a predetermined number of 465 or less), and the gaming state is changed. Control to return to the normal state is performed.

  The effect control unit 180 uses the display device 330 (an example of the effect device) based on the effect data selected by referring to the effect table stored in the effect table storage unit 195, and the sound device 340. Control regarding the sound effect performed using (an example of the effect device) is performed. For example, a lamp or LED is turned on or blinked according to the occurrence of a gaming event such as insertion of a medal, an operation on the bet button B0, the start lever SL, the stop buttons B1 to B3, or a change in the gaming state, or the display content of the liquid crystal display By changing the value or outputting sound from the speaker, the game is excited or the execution control for assisting the game is performed.

  In the gaming machine of the present embodiment, the effect control unit 180 includes a counter update unit 181 and a sub reel control unit 182.

  The counter updating means 181 adds a value corresponding to the number of medals paid out for each game to the stored value of the small role counter 196, and subtracts a value corresponding to the number of medals inserted for each game from the stored value of the counter. Do.

  More specifically, the counter updating unit 181 uses a value obtained by multiplying the number of medals to be paid out by a predetermined addition value (first coefficient: 256, for example) (the number of payouts × addition value). A value obtained by adding a predetermined subtraction value (second coefficient: for example, 100) to the memorized number of medals is added to the memorized value of 196, and the memorized value of the small role counter 196 By subtracting from, the stored value of the small combination counter 196 is updated for each game. If a predetermined number of medals are automatically inserted without requiring a medal owned by the player by replay winning, the process of subtracting the value from the stored value of the small role counter 196 is not performed.

  In the gaming machine of this embodiment, the counter updating unit 181 resets the stored value of the small combination counter 196 to an initial value (for example, 0) at the end of the BB state. By doing so, the medal acquisition status in the non-BB game section such as the normal state and the BB established state can be managed by the stored value of the small role counter 196. The counter updating means 181 can reset the stored value of the small role counter 196 to the initial value at various occasions such as when the gaming machine is turned off or when the setting information related to the gaming machine control processing is changed. it can.

  The sub reel control means 182 rotates the first sub reel SR1 to the third sub reel SR3 for each game, and stops the first sub reel SR1 to the third sub reel in a stop mode according to the stop mode of the first main reel MR1 to the third main reel MR3. Control to stop SR3 is performed.

  More specifically, the sub reel control means 182 rotates and drives the first sub reel SR1 to the third sub reel SR3 by a step motor based on a start signal from a start switch 230 that is operated by pressing the start lever SL. The step motor is controlled so that the rotation speed of the first sub-reel SR1 to the third sub-reel SR3 becomes a predetermined speed (about 160 rpm: a rotation speed of about 160 rotations per minute). Then, the sub reel control means 182 uses the first sub reels SR1 to SR3, which are rotationally driven by the step motor, with the pressing operation of the stop buttons B1 to B3 as a common stop trigger with the first main reel MR1 to the third main reel MR3. Control to stop the sub reel SR3 is performed. In the gaming machine of the present embodiment, pressing the stop button B1 is a common stop opportunity for the first main reel MR1 and the first sub reel SR1, and pressing the stop button B2 is the same as the second main reel MR2. This is a common stop trigger for the second sub reel SR2, and pressing the stop button B3 is a common stop trigger for the third main reel MR3 and the third sub reel SR3. In this way, the player feels a sense of unity as if both the first main reel MR1 to the third main reel MR3 and the first sub reel SR1 to the third sub reel SR3 are stopped by his / her own intention. Can be given to.

  That is, in the gaming machine of the present embodiment, when the stop switch 240 is activated by the player pressing the stop buttons B1 to B3, the sub reel unit 350 is driven to the step motor based on the reel stop signal from the stop switch 240. By stopping the supply of pulses (motor drive signals), control is performed to stop each of the sub reels of the first sub reel SR1 to the third sub reel SR3.

  The sub reel control means 182 determines the stop position of the sub reel corresponding to the pressed button among the first sub reel SR1 to the third sub reel SR3 each time the stop buttons B1 to B3 are pressed. Control is performed to stop the sub reel at the stopped position. Specifically, with reference to the stop control table for sub reels stored in the second stop control table storage unit 193b of the storage unit 190, the stop buttons B1 to B3 are pressed according to the pressing timing (mode of stop operation). The stop positions of the first sub reel SR1 to the third sub reel SR3 are determined, and control is performed to stop the first sub reel SR1 to the third sub reel SR3 at the determined stop position.

  Here, in the stop control table for sub reels stored in the second stop control table storage means 193b, the first at the time when the stop switch 240 is activated (when the pressing operation of each of the stop buttons B1 to B3 is detected). Correspondence between the positions of sub-reel SR1 to third sub-reel SR3 (press detection position) and the actual stop positions (or the number of sliding frames from the press detection position) of first sub-reel SR1 to third sub-reel SR3 is set. . In the present embodiment, since a stop control table for determining the stop positions of the first sub reel SR1 to the third sub reel SR3 is prepared according to the setting state of the lottery flag, in principle, the first main reel The first sub-reel SR1 to the third sub-reel SR3 are stopped in a stop mode corresponding to the stop mode of the reel MR1 to the third main reel MR3. However, in the gaming machine of the present embodiment, when the result of the internal lottery is a specific result, the sub reel control means 182 has the probability corresponding to the stored value of the small role counter 196 and the first main reel MR1 to the third main reel. A special stop mode irrespective of the stop mode of the reel MR3 is determined as the stop mode of the first sub-reel SR1 to the third sub-reel SR3.

  Specifically, when the result of the internal lottery is a loss and no winning combination has been won, the sub reel control means 182 has the first sub reels SR1 to SR1 with a probability corresponding to the stored value of the small role counter 196. An effect lottery (hereinafter referred to as a sub-reel roll lottery) for determining the stop mode (division) of the third sub-reel SR3 is performed. In the gaming machine of this embodiment, the stored value of the small combination counter 196 is compared with an initial value (for example, 0) which is a threshold value, and if the stored value of the small combination counter 196 is equal to or greater than the initial value, a special stop The reel selection lottery table is selected with reference to the effect lottery table for selecting the stop control table for stopping the first sub-reel SR1 to the third sub-reel SR3 with low probability, and the stored value of the small role counter 196 is less than the initial value. For example, a lottery drawing of the sub reels is performed with reference to an effect lottery table for selecting a stop control table for stopping the first sub reel SR1 to the third sub reel SR3 in a special stop mode with high probability. The effect lottery table is stored in the effect lottery table storage unit 197 of the storage unit 190. Then, the sub reel control means 182 determines a stop control table to be referred to based on the result of the sub reel appearance lottery, and thereby the first main reel MR1 to the third main reel with a probability corresponding to the stored value of the small role counter 196. The first sub-reel SR1 to the third sub-reel SR3 are stopped in a special stop mode that contradicts the stop mode of MR3.

  In the gaming machine of this embodiment, two types of stop control tables for sub reels that can be referred to when the result of the internal lottery is lost are prepared. In one stop control table, the stop buttons B1 to B3 are pressed. Regardless of the timing, the stop position of each sub-reel is set so that the first sub-reel SR1 to the third sub-reel SR3 are stopped at a so-called losing point (a stop mode indicating that the result of the internal lottery is losing). In the stop control table, when the BB symbol “blue 7” can be drawn into the display position on the winning determination line with respect to the main reel corresponding to the stop button first pressed among the stop buttons B1 to B3, the so-called losing eye To stop the first sub-reel SR1 to the third sub-reel SR3, the first of the stop buttons B1 to B3 If the BB symbol “blue 7” cannot be drawn into the display position on the winning determination line with respect to the main reel corresponding to the pressed stop button, the so-called chance (the possibility that BB has been won in the internal lottery) The stop position of each sub-reel is set so that the first sub-reel SR1 to the third sub-reel SR3 are stopped in the stop mode shown: a special stop mode).

  In the gaming machine of this embodiment, the sub reel unit 350 also includes a sub reel index 355 including a photosensor, and the sub reel control means 182 is based on a reference position signal detected by the sub reel index 355 every time the sub reel rotates once. Thus, the current rotation state of the sub-reel can be monitored by obtaining the rotation angle (the number of rotation steps of the rotation shaft of the step motor) from the reference position (the frame detected by the sub-reel index) of each sub-reel. It has become. That is, the sub reel control means 182 can obtain the position of the sub reel when the stop switch 240 is operated by obtaining the rotation angle from the reference position of the sub reel.

  In the gaming machine of this embodiment, the first sub reel SR1 to the third sub reel SR3 stop the rotating sub reel corresponding to the pressed stop button within 190 ms from the time when the stop buttons B1 to B3 are pressed. Control state is set. That is, in the stop control table for determining the stop position of each rotating sub-reel, the number of frames required from when the stop buttons B1 to B3 are pressed until each sub-reel stops is in the range of 0 to 3 frames (predetermined pull-in Range). Then, the sub reel control means 182 displays the sub display window when the pressing operation is performed on the stop button on the outer peripheral surface of the rotating sub reel corresponding to the stop button that has been pressed among the stop buttons B1 to B3. The pressing operation is performed so that the symbol corresponding to the winning combination is displayed at the display position in the sub display window DW2 with the symbol positioned within the range of 0 to 3 frames relative to the display position in the DW2 as a display target. Control is performed to stop the rotating sub-reel corresponding to the performed stop button.

  In the gaming machine of this embodiment, according to the symbol arrangement of the first sub-reel SR1 to the third sub-reel SR3 shown in FIG. 6, a plurality of BB symbols “blue 7” and replay symbols “ “RP”, bell symbol “BL”, and watermelon symbol “WM” are arranged in such a manner that the interval is within 3 frames, regardless of the timing of pressing the stop buttons B1 to B3, the order of pressing, etc. Can be drawn into the display position in the sub display window DW2.

  Note that the functional block configuration of the present embodiment can also be applied to a computer system (including a game system). In these systems, the function is realized by downloading a program that causes the computer to function as the game control means 100 of the present embodiment from an information storage medium such as a CD or DVD or a Web server on the Internet via a network. be able to. In the above computer system, the medal insertion switch 210, the bet switch 220, the start switch 230, the stop switch 240 and the like virtually function their functions with respect to operation means such as a keyboard, a pointing device (mouse, etc.), or a controller. This can be realized by assigning. In the above computer system, the main reel unit 310, the hopper unit 320, the sub reel unit 350, and the like are not essential constituent elements, and these device units are controlled by images displayed on the display (display device 330). Functions can be realized virtually.

2. Next, a control method employed in the gaming machine of the present embodiment will be described in detail.

  In the present embodiment, a method is employed in which the stop mode of the first sub reel SR1 to the third sub reel SR3 is changed according to the stored value of the small combination counter 196 (hereinafter referred to as a small combination counter value). Hereinafter, with reference to FIGS. 7 to 12, a method of stopping control of the first sub reel SR <b> 1 to the third sub reel SR <b> 3 according to the small combination counter value will be specifically described.

  In the gaming machine according to the present embodiment, when three medals having a specified number of coins are inserted in the game, a value obtained by multiplying the number of coins inserted (three) by a subtraction value (100) (number of coins × subtraction value = 300) is subtracted from the small role counter value for each game. In the example shown in FIG. 7, the bell is won in the third game. At this time, as shown in FIG. 8A, the first main reel MR1 to the third main reel MR3 are arranged so that the symbol combination “BL / BL / BL” indicating the winning pattern of the bell is displayed on the winning determination line. The first sub reel SR1 to the third sub reel SR3 are stopped so that the bell symbol “BL” is displayed at the symbol display position of each sub reel of the first sub reel SR1 to the third sub reel SR3. Then, 10 medals are paid out by winning the bell according to the stop mode of the first main reel MR1 to the third main reel MR3, and a value obtained by multiplying the number of payouts (10) by the addition value (256) ( The number of payouts × added value = 2560) is added to the small combination counter value, and the small combination counter value changes to a positive value (+1660).

  In the example shown in FIG. 7, the replay is won in the fifth game. At this time, as shown in FIG. 8B, the first main reel MR1 to the third main reel MR3 are set so that the symbol combination “RP / RP / RP” indicating the winning pattern of the replay is displayed on the winning determination line. The first sub reel SR1 to the third sub reel SR3 are stopped so that the replay symbol “RP” is displayed at the symbol display position of each sub reel of the first sub reel SR1 to the third sub reel SR3. At this time, the medal is not paid out depending on the replay winning, but the medal for the next game is automatically inserted for the next game without requiring the medal owned by the player. In this case, the small role counter value accompanying the insertion of medals is not subtracted and maintained.

  In the example shown in FIG. 7, the watermelon is won in the eighth game, but the watermelon is missed. In the gaming machine of the present embodiment, as shown in FIG. 9A, the stop combination of the first main reel MR1 to the third main reel MR3 is a combination of symbols “WM / WM / WM” indicating a watermelon winning pattern. Even when different from the stop mode displayed on the winning determination line, the first sub reels SR1 to SR1 are displayed so that the watermelon symbol “WM” is displayed at the symbol display positions of the sub reels of the first sub reel SR1 to the third sub reel SR3. The player is notified that the watermelon has been won by stopping the third sub reel SR3.

In the example shown in FIG. 7, the watermelon is won in the twelfth game, and the watermelon is won in this game unlike the ninth game. At this time, as shown in FIG. 9B, the first main reel MR1 to the third main reel MR3 are arranged so that the symbol combination “WM / WM / WM” indicating the watermelon winning pattern is displayed on the winning determination line. The first sub reel SR1 to the third sub reel SR3 are stopped so that the watermelon symbol “WM” is displayed at the symbol display position of each sub reel of the first sub reel SR1 to the third sub reel SR3. When the watermelon wins, six medals are paid out, and a value obtained by multiplying the number of payouts (6) by the addition value (256) (payout number × addition value = 1536) is added to the small role counter value. In the example shown in FIG. 7, BB is won in the 15th game, and when BB is won, BB lottery until BB wins. As the flag is maintained in the winning state, the first sub reel SR1 to the third sub reel SR3 are stopped as follows.

  First, when the main reel that stops first among the first main reel MR1 to the third main reel MR3 stops so that the BB symbol “blue 7” is displayed at the display position on the winning determination line, FIG. ), The sub reels are stopped so that the BB symbol “blue 7” is displayed at the display position of the sub reel corresponding to the main reel to be stopped among the first sub reel SR1 to the third sub reel SR3. As described above, when the main reel that stops first among the first main reel MR1 to the third main reel MR3 stops so that the BB symbol “blue 7” is displayed at the display position on the winning determination line, As shown in FIG. 10 (A), the first sub-reel is displayed so that the BB symbol “blue 7” is displayed at the display position of each sub-reel regardless of whether BB has won or BB has not won. The SR1 to the third sub reel SR3 are stopped, and the player is notified of the BB winning.

  On the other hand, the main reel that stops first among the first main reel MR1 to the third main reel MR3 stops so that the BB symbol “blue 7” is not displayed at any display position on the winning determination line. In this case, for example, as shown in FIG. 10B, if the sub reel corresponding to the main reel to be stopped among the first sub reel SR1 to the third sub reel SR3 is the first sub reel SR1, the display position of the first sub reel SR1. The first sub reel SR1 is stopped so that the watermelon symbol “WM” is displayed on the display. Unlike the case shown in FIG. 10B, if the sub reel corresponding to the main reel to be stopped is the second sub reel SR2 among the first sub reel SR1 to the third sub reel SR3, the display position of the second sub reel SR2 is set. If the second sub reel SR2 is stopped so that the bell symbol “BL” is displayed, and the sub reel corresponding to the main reel to be stopped among the first sub reel SR1 to the third sub reel SR3 is the third sub reel SR3, The third sub reel SR3 is stopped so that the replay symbol “RP” is displayed at the display position of the third sub reel SR3. As described above, the main reel that stops first among the first main reel MR1 to the third main reel MR3 stops so that the BB symbol “blue 7” is not displayed at any display position on the winning determination line. 10B, by stopping the first sub-reel SR1 to the third sub-reel SR3 so that the symbol combination “WM / BL / RP” corresponding to the so-called chance is displayed. , Informs the player that the winning expectation of BB is high.

  Further, in the example shown in FIG. 7, after BB is won in the 15th game, BB won the 19th game without winning the BB, and the replay is won in the 20th game. In the gaming machine of the present embodiment, when a small role or replay is won in a state where BB has been won, when stopping the first sub reel SR1 to the third sub reel SR3, Priority is given to the notification of winning the replay.

  For example, when the bell is won in the state where the BB is won as in the 19th game, the first sub reel SR1 to the third sub reel SR3 are displayed so that the bell symbol “BL” is displayed at the display position of each sub reel. Stop. By doing in this way, it is possible to prevent the player from missing the winning combination of the small role by letting the player know the winning of the small role having a lower winning priority than BB.

  Further, for example, when the replay is won in the state where the BB is won as in the 20th game, the first sub reel SR1 to the third sub reel SR3 so that the replay symbol “RP” is displayed at the display position of each sub reel. Stop. By doing in this way, it is possible to make the player grasp the replay winning with higher winning priority than BB, and to accurately grasp that BB cannot be won in the current game.

  By the way, in the gaming machine of the present embodiment, when the winning combination is not won in the internal lottery in the normal state, that is, when the result of the internal lottery is lost, the chance item is displayed according to the small role counter value. In this manner, a method of stopping the first sub reel SR1 to the third sub reel SR3 is employed.

  More specifically, if there is a loss in the internal lottery in the game in the normal state, whether or not the stop mode of the first sub reel SR1 to the third sub reel SR3 is a chance is determined by the sub reel lottery. is doing. If the sub reel reel lottery is not won, the replay symbol “RP” is displayed at the display position of the first sub reel SR1, as shown in FIG. Each sub reel is stopped so that the bell symbol “BL” is displayed at the display position of the second sub reel SR2, and the watermelon symbol “WM” is displayed at the display position of the third sub reel SR3, and the symbol combination “RP · BL / WM "is displayed. On the other hand, if the sub-reel appearance lottery is won, the BB symbol “blue 7” is drawn into the display position on the winning determination line with respect to the main reel corresponding to the stop button first pressed among the stop buttons B1 to B3. The sub-reel stop mode varies depending on whether or not the BB symbol “blue 7” can be drawn into the display position on the winning determination line with respect to the main reel corresponding to the stop button pressed first among the stop buttons B1 to B3. As shown in FIG. 11 (A), each sub-reel is stopped so that a so-called losing eye is displayed, and a winning determination line for the main reel corresponding to the stop button that is pressed first among the stop buttons B1 to B3. If the BB symbol “blue 7” cannot be pulled into the upper display position, as shown in FIG. Each sub reel is stopped so that the watermelon symbol “WM” is displayed at the display position of the screen SR1, the bell symbol “BL” is displayed at the display position of the second sub reel SR2, and the replay symbol “RP” is displayed at the display position of the third sub reel SR3. The symbol combination “WM / BL / RP” corresponding to the so-called chance (the BB winning expectation is high) is displayed.

  In the gaming machine of the present embodiment, when the small role counter value is less than the initial value (negative value), the sub-reel appearance lottery is performed so that the chance appearance rate at the time of a loss in the internal lottery is increased. When the small combination counter value is equal to or greater than the initial value (0 or positive value), the sub reel appearance lottery is performed so that the chance appearance rate at the time of a loss in the internal lottery is reduced.

  For example, when the small role counter value is a negative value (−140) as in the tenth game shown in FIG. 7, a sub-reel appearance lottery with a low winning probability is performed. When the small role counter value is a positive value (+760) as in the seventh game shown in FIG. 6, a sub-reel lottery with a high winning probability is performed. In this way, by stopping the first sub reel SR1 to the third sub reel SR3 in a special stop mode showing a chance according to the small role counter value, in the internal lottery according to the player's medal acquisition status It is possible to realize a game specification that produces an effect that enhances the player's expectation for winning the BB, and as a result, the player's willingness to play can be accurately evoked.

  Also, in the gaming machine of the present embodiment, when the small role counter value is less than the initial value, the result of the internal lottery when the medal acquisition status or medal consumption status is poor by increasing the chance appearance rate. It is possible to raise the player's expectation for the game and to motivate the player to continue the game, and to prevent a reduction in the operating rate of the gaming machine.

  Further, in the gaming machine of the present embodiment, when the small role counter value is equal to or larger than the initial value, by reducing the chance appearance rate, when the medal acquisition status and the medal consumption status are good, the internal lottery It is possible to prevent the player from expecting the player's expectation of the result.

  Next, an example of processing for realizing the control method of this embodiment will be described with reference to the flowcharts of FIGS. 12 and 13.

  In each game, as shown in FIG. 12, insertion acceptance processing for accepting insertion of medals necessary for playing the game is performed (step S10). In the insertion acceptance process, the insertion of a medal inserted into the medal insertion slot MI or a credit medal inserted by pressing the bet button B0 is received. In addition, if replay processing is performed based on winning a replay in the previous game, the rules automatically used in the previous game on the gaming machine side without requiring a medal owned by the player Automatically insert the same number of medals as the number of medals.

  When the insertion of a predetermined number (for example, three) of medals set as a game start condition is completed (Y in step S11), the operation of waiting for the start lever SL is waited (step S12).

  Subsequently, when the player depresses the start lever SL (Y in step S12), an internal lottery is performed (step S13), and driving is performed to a step motor that drives the first main reel MR1 to the third main reel MR3. Supply of a pulse is started and each main reel is rotationally driven (step S14). In the internal lottery, the winning combination is determined by comparing the random value acquired by pressing the start lever SL with the lottery table selected according to the gaming state, and the lottery flag of the winning combination (winning combination) Is set to the winning state.

  Then, when the rotation speed of each main reel whose rotation driving is started in step S14 reaches a predetermined speed (for example, 80 rpm), the operation of the stop buttons B1 to B3 is permitted, and the player presses the stop buttons B1 to B3. Then, the process of stopping the main reels by stopping the supply of the drive pulse to the step motor is performed (Y in step 15, step S16).

  When all of the first main reel MR1 to the third main reel MR3 are stopped (Y in step S17), a winning determination process is performed based on the stop mode of each main reel (step S18). If any winning combination is won as a result of the winning determination (Y in step S18), a winning time process corresponding to the winning combination is performed (step S19). For example, when a small combination wins, the number of medals to be paid out is determined based on the payout of the winning small combination, and a process of paying out medals of the determined number of payouts is performed.

  By the way, in the game of the present embodiment, when the gaming state is the normal state, the small role counter value update process and the first process are performed in accordance with the flowchart of FIG. 13 in parallel with the game progress process shown in the flowchart of FIG. Control processing of the sub reel SR1 to the third sub reel SR3 is performed.

  First, when the start lever SL is pressed (Y in step S100), the number of medals inserted in the insertion receiving process (step S10 in FIG. 12) (eg, three: excluding the automatic insertion associated with the replay winning) ) Is multiplied by a predetermined subtraction value (for example, 100) from the small combination counter value C (step S101).

  Next, the result of the internal lottery is acquired (step S102), and supply of drive pulses to the step motor that drives the first sub reel SR1 to the third sub reel SR3 is started to rotate each sub reel (step S103).

  If it is determined that the winning combination is won based on the result of the internal lottery acquired in step S102 (Y in step S104), stop control of the first sub reel SR1 to the third sub reel SR3 according to the type of winning combination A table is selected (step S105).

  On the other hand, if it is determined that the winning combination has not been won based on the result of the internal lottery acquired in step S102 (N in step S104), a small combination counter value C is acquired (step S106), and the acquired small combination counter is acquired. According to the value C, the stop control table for the first sub reel SR1 to the third sub reel SR3 is selected. Specifically, the small combination counter value C is compared with an initial value (for example, 0). If C ≧ 0 (Y in step S107), the sub reel appearance with a low winning probability (chance appearance rate) is obtained. A lottery A is performed, and a stop control table for the first sub reel SR1 to the third sub reel SR3 is selected based on the result of the sub reel appearance lottery A (step S108). If C <0 (N in step S107), the sub reel appearance lottery B with a high winning probability (chance item appearance rate) is performed, and the first sub reels SR1 to SR1 are selected based on the result of the sub reel appearance lottery B. A stop control table for the 3-sub reel SR3 is selected (step S109).

  When the stop buttons B1 to B3 are pressed (Y in step S110), the supply of drive pulses to the stepper motors of the sub reels corresponding to the pressed stop buttons is stopped, so that each sub reel is moved to steps S105, S108, Processing for stopping according to the stop control table selected in S109 is performed (step 111).

  When all of the first sub-reel SR1 to the third sub-reel SR3 are stopped (Y in step S112), the number of medals paid out in this game is different for each winning small role, and is 0 when there is no payout. The value obtained by multiplying a predetermined addition value (for example, 256) with respect to (substituting) is added to the small combination counter value C, and the series of processes is terminated (step S113).

3. Modifications The present invention is not limited to those described in the above embodiment, and various modifications can be made. Modifications will be introduced below. Note that the above-described embodiment and various methods described below as modified examples can be appropriately combined and employed as a control method for realizing the present invention.

  In the above embodiment, the case where the same number of main reels and sub reels are provided has been described as an example, but the number of main reels installed and the number of sub reels may be different. The sub reel may be virtually rotated and stopped by scroll-displaying a plurality of symbols in a predetermined order on the liquid crystal display.

  In the above embodiment, the case where the main reel and the sub reel are stopped by a common stop trigger has been described as an example. However, a stop button dedicated to the sub reel may be provided. Further, the sub reel does not have to stop in response to pressing of the stop button, and the sub reel stop timing can be arbitrarily set.

  Further, in the above embodiment, the sub-reel stop mode at the time of unfair winning of the combination is determined by lottery as to whether to make a normal loss or chance, but the sub-reel stop mode at the time of winning the predetermined combination is special. You may make it determine by lottery from the multiple types of stop mode including a stop mode.

  In the above embodiment, the case where the threshold value to be compared with the small combination counter value is only the initial value has been described as an example, but the threshold value is set in a plurality of stages, and the small combination counter value and the plurality of stages are set. The winning probability of the sub reel appearance lottery may be changed in relation to the threshold value.

  In this way, the sub reel appearance lottery is performed so that the chance item appearance rate increases as the small role counter value decreases, or the chance item appearance rate decreases as the small role counter value increases. Can be done.

  In the above embodiment, in the game after winning the BB, the first sub reel SR1 to the third sub reel SR3 are stopped according to the stop mode of the main reel that stops first among the first main reel MR1 to the third main reel MR3. Although the case where the aspect changes is described as an example, in the game after winning the BB, as in the game before the BB winning, when the result of the internal lottery is lost, the sub reel first lottery is performed. The stop mode of the sub reels SR1 to SR3 may be determined. In this case, as described above, the threshold value to be compared with the small role counter value is set in a plurality of stages, and the smaller the small role counter value, the more decisive the chance chance or BB win is in the game after BB winning. The sub-reel event lottery may be performed so that the event informing the user can easily appear.

  In the above embodiment, as the small combination counter value is higher, a special stop mode is less likely to be selected as the stop mode of the first sub reel SR1 to the third sub reel SR3, and as the small combination counter value is lower, the first sub reels SR1 to SR1 are selected. As a stop mode of the third sub-reel SR3, the case where the sub reel appearance lottery is performed so that a special stop mode is easily selected has been described as an example. As a stop mode of the three sub reels SR3, a special stop mode is easily selected, and as the small combination counter value is lower, it is difficult to select a special stop mode as the stop mode of the first sub reel SR1 to the third sub reel SR3. A sub reel appearance lottery may be performed. Even in this way, it is possible to produce an effect that gives the player a sense of expectation according to the player's medal acquisition status.
