Abstract

<P>PROBLEM TO BE SOLVED: To change a game state without being recognized by a player. <P>SOLUTION: A CPU 31 switches a prize group drawing table TBL1 corresponding to the game state and executes internal drawing. While the winning probability of a BB prize is zero in a CB game, drawing is executed by a prescribed probability in a normal game. For shifting to the CB game, the winning of a CB prize is a trigger. The CPU 31 does not put out tokens even when the CB prize is won and does not execute a winning performance using a liquid crystal display 64. Thus, the player can not recognize that the game state is changed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a slot machine.

  A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

  Here, the winning is generally determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever to determine which prize group will be won or lost, and internal lottery information indicating the lottery result is generated. Here, the prize group refers to a group of one or a plurality of roles and corresponds to a lottery category. That is, a prize group and a combination may correspond one-to-one, or a plurality of combinations may correspond to one prize group.

  In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid winning line, the reel stop timing is delayed, The reel is controlled so that the symbols constituting the winning combination do not stop on the valid winning line. The same applies to the combination corresponding to the prize that was not won in the internal lottery. Such control is called kicking control. On the other hand, if a prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly early, the pull-in control is performed so that the symbols constituting the role corresponding to the prize group stop on the winning line. The However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize group by internal lottery and align the winning prize group on an effective prize line. Winning any prize group in the internal lottery is called winning, and not winning any prize group is called losing. And, the fact that the symbols stopped on the winning line make up the winning combination is called winning, and the non-winning is not forming the winning combination. In non-winning cases, when the internal lottery result is lost, even if the internal lottery is won, the operation timing of the reel stop button is greatly shifted, so that the role corresponding to the winning prize is not established, so-called Includes missing items.

  Such a slot machine can execute a plurality of types of games such as a big bonus game and a regular bonus game in addition to the normal game. The expected value of the number of medals that can be acquired per game is larger in the big bonus game and the regular bonus game than in the normal game. The transition from the normal game to the big bonus game is conditional on winning the BB prize, and the transition to the regular bonus game is conditional on winning the RB prize. The internal lottery described above is executed for each game, and the internal lottery result is usually not carried over to the next game. However, if the BB prize or the RB prize is won by the internal lottery, the internal lottery result will be continued until winning. Carry over to the game.

  As described above, winning the prize is a necessary condition for winning the prize by internal lottery, and further, it is necessary and sufficient condition to operate the reel stop button at a predetermined timing. However, there is known a slot machine capable of executing a special game that does not require an internal lottery for winning (Patent Document 1). In this type of special game, the reels are stopped regardless of the result of the internal lottery. That is, the kicking control described above is not executed. Therefore, if the player operates the reel stop button accurately aiming at a desired symbol, a prize is won.

Japanese Patent Publication No. 5-74391

  By the way, from the point of view of gambling, the law places a certain limit on the number of players. Here, the payout rate is the total number of medals inserted by the player into the slot machine per a predetermined number of games, and the total number of medals paid out from the slot machine per the predetermined number of games. It is given by the ratio of the total number of output sheets to the number of input sheets. A lower limit value and an upper limit value are set for the payout rate.

  Since a large amount of medals are paid out in the big bonus, if the winning probability of the BB prize is set too high, the upper limit of the payout rate will be exceeded in an actual game. On the other hand, if the winning probability of the BB prize is set too low, it will fall below the lower limit of the payout rate. For this reason, the winning probability of the BB prize has to be set within a limited range. As a result, the wave period of the ball is increased, and it is difficult to sharpen the ball.

  This invention is made | formed in view of the situation mentioned above, and makes it a solution subject to give freedom to the winning probability of a BB prize.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  In the slot machine according to the present invention, the player gives a display means (D) having a plurality of display rows (R1, R2, R3) each having a plurality of frames and capable of variable display, and an instruction to start the variable display. Start operation means (6) for inputting, and stop operation means (7a, 7b, 7c) for a player to input an instruction for stopping the variable display, the display means (D) being variable. When the stop mode on the winning line in the state where the display is stopped is a predetermined mode, a prize is won, and the award includes a big bonus prize, a second prize, a special prize, and a gaming state that change the gaming state. The game can be executed in a plurality of gaming states including a normal state, a big bonus state, and a second state, including a plurality of small role awards that are not changed, and the big bonus state is one game than the normal state In the slot machine having a large expected value of the number of game media that can be obtained in the game, the winning line crosses the display lines (R1, R2, R3) and the display lines (R1, R2, R3). And a line that does not form a straight line, and a plurality of prizes including the big bonus prize, the second prize, the special prize, and the plurality of small part prizes, and a plurality of areas corresponding to loses. A lottery table (TBL11), a second lottery table divided into a plurality of areas corresponding to a plurality of awards and loses not including the big bonus award, the second award and the special award, the big bonus award, A third lottery table (TBL12) that is divided into a plurality of areas corresponding to a plurality of awards and loses including the special award and the plurality of small role awards, excluding the second award; Table selection means (31) for selecting the first lottery table in the normal state, selecting the second lottery table in the big bonus state, and selecting the third lottery table in the second state. And a number sequence generating means (33) for generating the number sequence data, a plurality of prizes and losers by comparing the value of the data sampled from the number sequence data and the value of the prize group lottery table selected by the table selection means. 1 is selected and the lottery means (31) for generating a lottery information indicating the winning prize or the lost prize, and the stop operating means (7a, 7b, 7c) are stopped. Detected as an operation timing and constitute a winning prize indicated by the lottery information located within a predetermined movement range from the symbol position at the stop operation timing And a stop control means (31) for controlling the display means (D) so that the variable display is stopped by drawing the symbol into the winning line, wherein the stop control means (31) has the lottery information as the second lottery information. In the base game showing a prize, the symbols constituting the second prize located within a predetermined movement range from the symbol position at the stop operation timing are drawn into a winning line that does not form the straight line among the winning lines. The display means (D) is controlled so that each display row (R1, R2, R3) stops.

From the viewpoint of suppressing the player's euphoria, there may be an upper limit on the number of game media that the player can acquire. In this case, the winning probability of the big bonus award is lowered so that the winning probability of the big bonus award in the normal state does not exceed the above-described upper limit value. However, since the winning probability of the big bonus award in the normal state is fixed, the wave of appearance is moderate. The present invention provides a second state as a gaming state in addition to the normal state and the big bonus state, and the third lottery table corresponding to the second state has no division corresponding to the big bonus prize. The winning probability of the big bonus award in the normal state can be set higher than in the case of not providing it, and it is possible to give a degree of freedom to the period of the outgoing balls.
The big bonus award may be, for example, a BB award that shifts to a big bonus game, and the special award may be an FB award. In the present invention, whether or not the internal lottery is executed in the “next game won the special prize” is not questioned. In addition, in the “next game that won a special prize”, when an internal lottery is not executed, a flag is forcibly set, and a stop mode corresponding to a predetermined prize is permitted with reference to the flag. A predetermined movement range may be set as described above. On the other hand, when executing the internal lottery, even if the lottery result is lost, it may be permitted to enter a stop mode corresponding to a predetermined prize. Furthermore, if any prize is won, a special stop control may be executed if the prize is a predetermined prize.

  Here, the display means includes a plurality of display rows each having a plurality of frames, and the stop control means is predetermined in the next game winning the special prize regardless of the determination by the lottery means. Preferably, the predetermined movement range is set to 0 frame or 1 frame for at least one display row so as to permit a stop mode corresponding to the award.

Further, the width of each section corresponding to the one or more small winning prizes in the first lottery table and the width of each section corresponding to the one or more small winning prizes in the third lottery table. It is preferable to set them so as to match each other. In this case, even if the number of small winning prizes is counted in an actual game, it can be determined whether the state is the normal state or the second state.
Further, when the average number of games that the second state is expected to continue is executed and the number of wins in the plurality of small role awards is counted, even if a statistical test is performed based on the number of wins, 50% The width of each division corresponding to the plurality of small prizes in the first lottery table and the third lottery table is set so that the normal state or the second state cannot be determined with the above probability. It may be determined.

  Further, the width of the section corresponding to the special prize in the third lottery table may be set larger than the width of the section corresponding to the special prize in the first lottery table. Here, the probability of winning the special prize may be increased in a range of 5%, for example. Furthermore, when the average number of games expected to continue in the second state is executed and it is assumed that the number of times of winning a special prize is counted, even if a statistical test is performed based on the number of winning prizes, it is 50% or more. The probability of winning the special prize in the second state may be different from that in the normal state so that it is impossible to determine whether the state is the normal state or the second state. This makes it impossible to determine whether the player is in the normal state or the second state by counting the number of times the special prize is won.

  Further, the slot machine described above includes a winning information generating means for generating winning information indicating a winning prize, and notifies the player that the big bonus prize has been won when the winning information indicates the big bonus prize. When the winning information indicates the second prize, it is preferable to provide a notifying means for not notifying the player that the second prize has been won. In this case, since the player is not notified even if the second prize is won, it can be kept secret to the player that the gaming state has shifted to the second state.

Further, the slot machine described above is configured to pay out the game medium, a winning information generating means for generating winning information indicating a winning prize, and paying out a quantity of the gaming medium according to the winning information. It is preferable to provide a payout control means for controlling the payout means and setting the number of game media to be paid out to zero when the winning information indicates the second prize. In this case, since the payout means does not pay out the game medium even when winning the second prize, it is possible to prevent the player from knowing that the game state has changed from the normal state to the second state due to the payout of the game medium.
In the slot machine described above, the display means (D) includes a plurality of display columns (R1, R2, R3) on which a plurality of types of symbols are displayed, and the winning information generation means (31) The betting number setting means (15, 5) for generating the winning information in accordance with the pattern mode stopped at the winning position provided so as to cross the display row (R1, R2, R3), and for setting the betting number by the player. And a specifying means (31) for specifying the winning position according to the set number of bets, wherein at least one of the symbols at the winning position corresponding to the second prize is a different type of symbol. preferable. In this case, since the types of symbols at the winning position are not the same, it is difficult for the player to detect that the player has won the second prize. All the symbols at the winning position may be different.

  ADVANTAGE OF THE INVENTION According to this invention, the wave of a ball with a short period can be made, observing the regulation of a ball output rate. In addition, the player will not be aware of the normal state or the second state.

<1: External configuration of slot machine>
FIG. 1 is a perspective view showing an appearance of the slot machine 1 according to the first embodiment of the present invention. The housing of the slot machine 1 includes a main body 2 and a front door 3 attached to the front surface of the main body 2. A liquid crystal display device 64 for presenting predetermined information to the player is provided on the upper stage of the front door 3. The panel display portion D in the middle stage of the front door 3 is provided with three vertically long display windows 4a, 4b, and 4c. The display windows 4a, 4b, and 4c are formed of a transparent material such as acrylic resin. Further, three winning lines L1 to L5 are provided horizontally and obliquely on the display windows 4a, 4b, and 4c.

  In addition, an auxiliary display unit 20 is provided on the left side of the display window 4a. The auxiliary display unit 20 is composed of five LEDs respectively corresponding to the pay lines L1 to L5. When the player inserts medals or performs a bet operation to be described later, the number of pay lines L1 to L5 corresponding to the number of bets becomes valid. In this slot machine 1, the winning line L1 is valid when the number of bets is one, the winning lines L1 to L3 are valid when the number of bets is two, and the winning lines L1 to L1 when the number of bets is three. L5 becomes effective. Each LED constituting the auxiliary display unit 20 is turned on when the corresponding winning line L1 to L5 is valid, and is turned off when the corresponding winning line L1 to L5 is invalid. Thus, the player can know which winning lines L1 to L5 are valid.

  Inside the panel display D, three rows of left, middle and right reels R1, R2 and R3 each having a plurality of types of symbols drawn on the outer peripheral surface thereof are rotatably provided. FIG. 2 shows the structure of the left, middle, and right reels R1, R2, and R3, and FIG. 3 shows the detailed structure of the right reel R3. Each of the reels R1 to R3 has an annular shape, and various symbols are printed on its surface (surface visible from the display windows 4a to 4c). A light shielding film S that shields light is formed on the back surface of the right reel R3 except for a part thereof. In the portion where the light shielding film S is formed, light is not transmitted even if light is irradiated from the back side. On the other hand, the light shielding film S is not formed on each design portion, and the uneven member P for scattering light is formed on the back surface of the right reel R3. In addition, the reel of each design part is white and translucent. In the example shown in FIG. 3, the concavo-convex member P is formed inside the contour portion of the symbol “7”.

  A right reel illumination unit 670 is disposed on the inner peripheral surface side of the right reel R3. The right reel lighting unit 670 includes upper, middle, and lower shades partitioned by walls. A light source 67 is provided in each of the upper, middle, and lower shades. As the light source 67, a cold cathode tube, an LED, or a light bulb can be used.

  Further, a light shielding piece 491 is provided on a part of the right reel R3 so as to protrude from the reel body, and crosses the photocoupler 492 when the right reel R3 rotates. The structure of the left reel R1 and the middle reel R2 and the peripheral configuration thereof are the same as the structure of the right reel R3 and the peripheral configuration thereof described with reference to FIG.

  Returning to FIG. 1, the description will be continued. Below the display windows 4a, 4b, and 4c, there is provided an operation unit OP on which various operation members for a player to execute a game are arranged. The operation unit OP includes a medal slot 5, a start lever 6, left / middle / right reel stop buttons 7a, 7b, 7c, a credit button 8, and a BET button 15.

  The medal slot 5 is provided below the display window 4c so that medals can be inserted. When one medal is inserted, the winning line L1 is activated, when two medals are inserted, the winning lines L1 to L3 are activated, and when three medals are inserted, the winning lines L1 to L5 are activated. Further, when the player inserts more than 3 medals, the slot machine 1 stores the number of medals of 4 or more as credits. The slot machine 1 includes a storage device therein. The storage device stores the medals acquired by the medals inserted into the slot machine 1 so that the player can operate the buttons and other devices without newly inserting medals into the slot machine. It is a device that can provide a predetermined number of medals from among medals in order for a game, and is used for the game based on the total number of medals entered in the slot machine and medals acquired by the game. It is possible to record the number obtained by subtracting the total number of objects by an electromagnetic method.

  The BET button 15 is provided on the lower left side of the display window 4a. The BET button 15 is used for designating the number of medals bet by the player in one game. By operating the BET button 15 by the player, the stored medals can be bet without inserting medals from the medal insertion slot 5. Therefore, the winning lines L1 to L5 are appropriately enabled according to the number of medals designated by operating the BET button 15. The relationship between the number of medals designated by the operation of the BET button 15 and the valid pay lines L1 to L5 is the same as when medals are directly inserted.

  The start lever 6 is provided below the BET button 15. The start lever 6 is used by the player to instruct the start of the game. When the player depresses the start lever 6, the reels R1, R2, and R3 start to rotate all at once, and the symbols in the display windows 4a, 4b, and 4c are variably displayed.

  Left, middle and right reel stop buttons 7 a, 7 b and 7 c are provided on the right side of the start lever 6. The left, middle and right reel stop buttons 7a, 7b and 7c are used to stop the three rows of left, middle and right reels R1, R2 and R3 rotating in the display windows 4a, 4b and 4c, respectively.

  On the right side of the reel stop button 7c, a credit check button 8 is provided for returning medals stored as credits to the medal tray 10.

<2: Role>
FIG. 4 shows an example of symbols displayed on the left / middle / right reels R1, R2, and R3. As shown in the figure, 21 symbols and 7 types of symbols are displayed on each reel R1, R2, R3, and symbol numbers PN = 1 to 21 are assigned to the symbols.

  In a game by the slot machine 1, when a predetermined combination of symbols is aligned on the winning lines L1 to L5 enabled by inserting medals, the number of medals corresponding to the aligned symbols is paid out. The medal is inserted into the slot machine 1 when starting the game, and is necessary for the player to continue the game. That is, a medal can be said to be a medium (game medium) having a game value such as continuation of a game. In this case, the medal corresponds to the game value. Note that an information recording medium such as a magnetic card or an IC card in which information corresponding to the number of medals is recorded is also included in the game medium.

  Of the arrangement (combination) of symbols, the one that gives game value is called “role”, and is distinguished from “valueless” non-winning. The game value refers to a privilege given to the player, and includes transferring a predetermined amount of medals to the player and shifting from one type of game to another type of game. The type of game value given as a result of one game is called “prize”, and obtaining “prize” is called “winning”. The awards are roughly classified into a start prize for shifting from a normal game to another type of game and a small role award (payout prize) with a medal payout. The start prize may be accompanied by a medal payout, or may not be paid out.

  The types of games that can be executed by the slot machine 1 (game state) include a normal game, a regular bonus game (hereinafter referred to as RB game), a big bonus game (hereinafter referred to as BB game), and a challenge bonus game (hereinafter referred to as “game”). CB game), free bonus game (hereinafter referred to as FB game), and replay game. The RB game start prize is called RB prize, the BB game start prize is called BB prize, the CB game start prize is called CB prize, the FB game start prize is called FB prize, and the replay game start prize is called replay prize. In the RB award, the BB award, and the FB award, 15 medals may be paid out by winning, but no medals are paid out even if the CB award and the replay award are won.

The CB game is a game in which the winning probability of the FB prize in the internal lottery is different from that of the normal game, and the winning probability of the FB prize of the present embodiment is slightly higher in the CB game than in the normal game. Note that the CB game may have a lower probability of winning the FB prize than the normal game. The CB game end condition may be, for example, a condition that a predetermined number of games such as 100 games are consumed, or a condition that the number of medals acquired during the CB game reaches a predetermined number. Alternatively, it may be a condition that the number of medals acquired during the FB game performed during the CB game reaches a predetermined number. Furthermore, winning conditions or winning a predetermined prize (for example, RB prize) may be set as the end condition. In addition, when a single bonus (hereinafter referred to as SB) award is adopted, winning of the SB award may be set as an end condition. When winning the SB prize, the JAC game is executed only for the next game won and the SB prize flag is not carried over. In this case, it is preferable to perform push order control, timing push, non-winning control, etc. in reel control even if the SB prize is won, so that they are not substantially aligned. By executing such control, it is useless to make a single bonus every time, so it does not depend on the skill of the player. Further, if the winning symbol set of the SB award is a different set of symbols of one or more types as in the BB during CT, the existence of the single bonus can be hidden from the player. As a result, the CB game can be ended without the player realizing it.
In the FB game, stop control is executed for at least one reel regardless of the result of the internal lottery, and the operation is completed in one game. Therefore, in the FB game, kick control is not executed for at least one reel. In the following description, the FB game in the CB game is referred to as the FB in CB, and the FB game won in the base game is referred to as the single FB.

  The replay game refers to a game that can be played without inserting medals (including using the medals for games by operating buttons and other devices related to the storage device). The RB game ends when the JAC game is played 12 times or a maximum of 8 times is won. The JAC game is played by betting one medal and enabling only the central pay line L1. JAC games will adopt the JAC Award. When winning the JAC Award, the slot machine 1 pays out 15 medals.

  The BB game has a higher probability of winning the RB prize than the normal game. However, there is a limit to the number of medals that the player can acquire during the BB game, and the BB game is terminated before the predetermined number is exceeded. In the following description, in order to distinguish between RBs in the BB and RBs that have won alone, the former is referred to as RB in BB and the latter is referred to as single RB.

  On the other hand, the small role prize includes a cherry prize with two medal payouts, a bell prize with five medal payouts, and a watermelon prize with seven medal payouts. The relationship between the composition of the combination and the prize is as shown in FIG.

  1) Red 7 Role This role is a sequence of symbols with symbol numbers PN = 1 and 7 on the left reel R1, symbols with symbol number PN = 9 on the middle reel R2, and symbols with symbol numbers PN = 1 and 9 on the right reel R3. It is. The red 7 role corresponds to the BB prize and is an opportunity to shift from the base game to the BB game.

  2) White 7 role This role is a sequence of symbols with symbol number PN = 12 on the left reel R1, symbols with symbol numbers PN = 1 and 11 on the middle reel R2, and symbols with symbol number PN = 13 on the right reel R3. . The white 7 role corresponds to the FB award and is an opportunity to shift from the normal game and the CB game to the FB game.

  3) BAR Role This role is a sequence of symbols of symbol number PN = 17 in the left reel R1, symbols of symbol number PN = 14 in the middle reel R2, and symbols of symbol numbers PN = 5 and 18 in the right reel R3. The BAR combination corresponds to a single RB award and becomes an opportunity to shift from the base game to the RB game.

  4) CB Role This role consists of symbols with symbol number PN = 3, 5, 9, 14, or 19 on the left reel R1, symbols with symbol number PN = 4, 8, 13, 17 or 21 on the middle reel R2, right This is an arrangement of symbols of symbol number PN = 2, 6, 10, 15 or 19 on the reel R3. That is, it is an arrangement of symbols “Plum-Bell-Plum”. The CB combination corresponds to the CB award and is an opportunity to shift to the CB game. Note that the symbols constituting the CB combination are arranged so that the player can stop the winning line (winning position) on the winning line (winning position) regardless of the timing at which the player operates the reel stop buttons 7a, 7b, 7c. . When the CB combination is won by internal lottery, the reels R1 to R3 may be controlled so that the symbols constituting the CB combination are drawn on the winning line in the reel control.

  5) Bell role This role consists of a symbol number PN = 4, 8, 10, 15, or 20 on the left reel R1, a symbol number PN = 4, 8, 13, 17 or 21 on the middle reel R2, right This is an arrangement of symbols of symbol number PN = 4, 8, 12, 17 or 21 on the reel R3. When a bell role is established in a normal game, a BB game, or a CB game, a bell prize is won.

  6) Watermelon role This role consists of the symbol number PN = 2, 6, 11, 16 or 21 on the left reel R1, the symbol number PN = 2, 6, 10, 15 or 19 on the middle reel R2, the right reel This is an arrangement of symbols of symbol number PN = 3, 7, 11, 16, or 20 in R3. When a watermelon role is established in a normal game, a BB game, or a CB game, a watermelon prize is won.

  7) Cherry role This role only needs to stop when the symbol number PN = 13, 18 on the left reel R1 is activated among the winning lines L1 to L5, regardless of the stop position of the other reels. is there. When the cherry role is established in the base game, the BB game, or the CB game, a cherry prize is won.

  8) Plum role This role consists of a symbol number PN = 3, 5, 9, 14, or 19 on the left reel R1, a symbol number PN = 3, 7, 12, 16, or 20 on the middle reel R2, right This is an arrangement of symbols of symbol number PN = 2, 6, 10, 15 or 19 on the reel R3.

<3: Electrical configuration of slot machine>
FIG. 6 is a block diagram showing a control device that controls the game processing operation in the slot machine 1 and a circuit configuration that includes peripheral devices related to the present invention among those constituting the slot machine 1.

  The control device includes main board 30A and sub board 30B as main components. The main board 30A includes a CPU 31, a clock generation circuit 32, a sequence generation circuit 33, a RAM 34, a ROM 35, a transmission timing control circuit 36, a data transmission circuit 37, an input port 38 and an output port 39.

  The CPU 31 is connected to each component of the main board 30A excluding the transmission timing control circuit 36 via a bus (not shown). The CPU 31 executes the first control program CP1 and controls each component. The first control program CP1 describes how to operate the entire slot machine 1. For this reason, the CPU 31 functions as a control center of the slot machine 1. The clock generation circuit 32 includes an oscillation circuit including a crystal resonator, generates a reference clock signal CLK having a fixed period, and supplies the reference clock signal CLK to the CPU 31 and the number sequence generation circuit 33.

  The sequence generator 33 is composed of a high-speed ring counter, and counts the reference clock signal CLK to generate count data CD. The numerical value range of the count data CD is, for example, 0 to 65535, depending on the contents stored in the prize group lottery table TBL1 described later. The count data CD can be input to the CPU 31 via the input port. The CPU 31 detects the timing when the player depresses the start lever 6 and reads the count data CD via the input port at the timing. Sampling data SD is generated.

  Since the player cannot know the value of the count data CD, the timing at which the start lever 6 is pushed down by the player is random. Therefore, the value of the sampling data SD is equivalent to a value sampled from a random number. Since the sequence generator 33 operates in synchronization with the reference clock signal CLK, the cycle of the count data CD is extremely short. For example, when the frequency of the reference clock signal CLK is 30 MHz, the time required for the value of the count data CD to change from “0” to “65535” is 2.2 msec. Therefore, even if the player can know the value of the count data CD by unauthorized means, it is impossible to cause the CPU 31 to generate sampling data SD having a desired value by operating the start lever 6.

  Next, the RAM 34 functions as a work area of the CPU 31 and stores intermediate results of arithmetic processing, data generated as necessary, flags used for various controls, and the like. For example, internal lottery data ISD indicating the result of the internal lottery is stored in the RAM 34.

  In addition to the first control program CP1, the ROM 35 stores a prize group lottery table group TBL1, a stop table group TBL2, a winning symbol combination table TBL3, and the like. In the winning symbol combination table TBL3, a winning combination and a medal payout number are stored in association with each other.

  Since the control of the slot machine 1 requires control according to the difference in game value, it is convenient to classify various roles by paying attention to the game value. In the slot machine 1 of the present embodiment, one prize group is assigned to each winning combination, but one or more winning combinations may be assigned to one winning group.

  Next, the prize group lottery table group TBL1 includes a plurality of prize group lottery tables. CPU31 performs internal lottery using the prize group lottery table selected according to the gaming state. As a prize group lottery table, a table used for a normal game, a table used for a BB game, a table used for an RB game, a table used for a CB game, a table used for an FB game, an FB game in a CB Table is prepared.

  FIG. 7A shows the stored contents of the prize group lottery table TBL11 for the base game. As shown in this figure, the prize group lottery table TBL11 stores lottery division data in the first to ninth storage areas ADR1 to ADR9, respectively. The value of the lottery category data indicates the width of the lottery category corresponding to each prize group. For example, the lottery classification data stored in the first storage area ADR1 corresponds to the loss, and the value is “59536”. The lottery classification data stored in the ninth storage area ADR9 corresponds to the BB prize, and its value is “200”.

  FIG. 8 is a flowchart showing the operation of the CPU 31 in the internal lottery process using the prize group lottery table TBL11. First, the CPU 31 performs an initialization process (step S1). Specifically, the value of the variable N is reset to “0” and the value stored in the internal register is reset to “0”.

  Next, the CPU 31 stores the sampling data SD in the internal register (step S2), and subsequently changes the value of the variable N to N + 1 (step S3). Thereafter, the CPU 31 reads the lottery classification data from the Nth storage area (step S4). In the process immediately after the initialization process, since the value of the variable N is “1”, the lottery classification data is read from the first storage area ADR1. The value in this case is “59536”.

  Next, the CPU 31 reads the stored contents of the internal register, adds the read data value and the lottery classification data value, and stores the added value in the internal register (step S5). As a result, the content stored in the internal register is updated from the original data value to the added value.

  Next, the CPU 31 determines whether or not the added value is greater than or equal to the reference value (step S6). The reference value is equal to the sum of the values of the lottery classification data stored in the first to ninth storage areas ADR1 to ADR9.

  If the added value is less than the reference value, the CPU 31 returns the process to step S3, and repeats the processes from step S3 to step S6 until the added value becomes equal to or greater than the reference value. When the added value is equal to or greater than the reference value, the CPU 31 advances the process to step S7, determines a prize group according to the value of the variable N, and generates internal lottery data ISD. Specifically, when N = 1, it is a loss, when N = 2, a replay prize, when N = 3, a cherry prize, when N = 4, a bell prize, when N = 5, a single FB prize, when N = 6, a watermelon It is determined that the CB prize is won when N = 7, the RB prize when N = 8, and the BB prize when N = 9. As a result, as shown in FIG. 6, the correspondence between the sampling data SD and the prize group is lost at SD = 65535-6000, replay prize at SD = 5999-4300, cherry prize at SD = 4299-3300, SD = 3299 to 2400 for the Bell Prize, SD = 2399 to 1600 for the Single FB Award, SD = 1599 to 900 for the Watermelon Award, SD = 899 to 500 for the CB Award, SD = 499 to 200 for the RB Award SD = 199 to 0 corresponding to the BB prize.

  Then, the CPU 31 generates internal lottery data ISD based on the determination result. The internal lottery data ISD includes a BB award for the first bit, an RB award for the second bit, a CB award for the third bit, a bell award for the fourth bit, a watermelon award for the fifth bit, a cherry award for the sixth bit, A replay award is assigned to the 7th bit, and a single FB award is assigned to the 8th bit. If any prize is won by internal lottery, the CPU 31 sets the value of the corresponding bit to “1”, otherwise sets the value of the bit to “0”. Therefore, by referring to the internal lottery data ISD, it is possible to know whether the player has won or lost, and the winning group that has won.

  In the following description, the first bit of the internal lottery data ISD is called a BB winning flag, the second bit is called an RB winning flag, and the third bit is called a CB winning flag. Then, setting each flag to “1” is referred to as setting, and setting to “0” is referred to as clear. With regard to a small role, even if a game is won by an internal lottery, no medal will be paid out unless the game is won. However, for the RB prize, the BB prize, and the CB prize, when winning in an internal lottery of a certain game, the BB winning flag, the RB winning flag, and the CB winning flag are not cleared without winning in the game. The BB winning flag, the RB winning flag, and the CB winning flag are maintained until winning in the game. This is called carrying over the winning flag. As described above, the internal lottery is executed for each game, and the internal lottery data ISD is generated. The lottery result is valid only in the game except for winning the RB prize, the BB prize, and the CB prize. Thus, even if the winning flag is carried over, the internal lottery is executed for each game. For example, when the watermelon prize is won in the internal lottery in the game where the winning flag of the BB prize is carried over, the internal lottery data ISD In this state, the values of the first bit and the fifth bit are set to “1”. Further, if neither game is won in this game, only the fifth bit is cleared to “0” and the first bit remains set to “1”.

  FIG. 7B shows the stored contents of the prize group lottery table TBL12 for the CB game. As shown in this figure, the prize group lottery table TBL12 stores lottery division data in the first to seventh storage areas ADR1 to ADR7, respectively. This prize group lottery table TBL12 has no lottery classification corresponding to the BB prize and the CB prize, and the width of the lottery classification corresponding to the FB prize (FB prize in CB) is the FB prize (single FB) of the prize group lottery table TBL11. It is different from the prize group lottery table TBL11 in that it is larger by “1” than the width of the lottery section corresponding to “prize”. The lottery probability between the CB FB award and the single FB award may be set in any way as long as it is set so that the player does not know the difference. For example, the lottery probability of the FB award in the CB may be within a range of ± 5% based on the lottery probability of the single FB award.

  FIG. 9 shows the relationship between the type of prize and the lottery value for each gaming state. In this figure, the circle is drawn by lottery. The triangle may be drawn or not. X is not a lottery. The stars set the winning flag regardless of whether or not they have a lottery. In this example, in the FB game, the internal lottery is executed for the single RB prize, and the internal lottery may be executed for the BB prize, the CB prize, the FB prize, the watermelon prize, and the re-game prize. On the other hand, for the Bell Prize and Cherry Prize, a winning flag is set regardless of whether there is an internal lottery. Therefore, even if the result of the internal lottery is lost, the winning flags of the bell prize and the cherry prize are set, so there is a possibility that these prizes will be won. In this example, the internal lottery is executed in the FB game and the CB-in-CB FB game, but the winning flag corresponding to a predetermined prize may be validated without executing the internal lottery.

  In the CB game, the fact that the lottery probability of the BB prize is zero has an important meaning in controlling the appearance. In the slot machine, an upper limit value and a lower limit value are set for the payout rate from the viewpoint of suppressing the gambling feeling of the player, and it is required that the output be changed within this range. In the BB game, a large number of medals can be obtained with a short number of games. For this reason, it is necessary to select the winning probability of the BB prize so that the payout rate changes within the range between the upper limit value and the lower limit value. Here, the payout rate is given by the ratio of the total number of input medals, which is the total number of medals inserted, to the total number of output medals, which is the total number of medals paid out, in a predetermined number of games in the past based on the current game. If the BB prize is always drawn with a certain probability, the winning probability of the BB prize must be set low because it is necessary to set the winning probability in consideration of winning the BB prize within a short period of time. I do not get. As a result, the output ball tends to be a wave with a long period between the upper limit value and the lower limit value. In the CB game adopted in the present embodiment, the winning probability of the BB prize is lower than that in the normal game and is zero. Therefore, if the base game and the CB game are viewed over a long period of time, the winning probability of the BB prize can be made substantially the same as the case where the winning probability of the BB prize is fixed. The transition can be made within the range of the upper limit value and the lower limit value. And the probability of winning the BB prize in the base game can be set to a high probability compared to the case where the CB game is not adopted, and it is possible to shorten the period of the wave of the ball while complying with the regulation of the ball-out rate. It becomes. As a result, it is possible to provide a sharp game to the player.

  By the way, if the player knows whether the game is in the normal game or the CB game, the player stops the game when the game is shifted to the CB game. Therefore, the slot machine of this embodiment has the following features so that the player is not informed of the transition to the CB game. First, no medals are paid out even if the CB prize is won. Secondly, no effect of winning the CB prize is performed. Thirdly, the winning outcomes are not arranged in the same pattern. Fourthly, at least the first game effect of the CB game is an effect (including no effect) performed in the normal game.

  Next, the stop table group TBL2 is composed of a plurality of stop tables. In each stop table, the symbol number PN (the symbol number at the reference position) displayed on the central pay line L1 and the advance frame number data indicating the advance frame number (the number of moving symbols) are stored in association with each other. . Here, the number of advance frames is a symbol that advances from when the player depresses each of the left / middle / right reel stop buttons 7a, 7b, 7c until the left / middle / right reels R1, R2, R3 stop. A number.

  Since each of the left, middle, and right reels R1, R2, and R3 rotates at high speed, even if the player operates the stop button aiming at a specific symbol, skill is required to stop the desired symbol. There are individual differences in the mastery of the stop button operation. In particular, it is difficult for a player with low moving eyesight to stop a desired symbol. On the other hand, a highly skilled player can operate the stop button when a desired symbol is displayed on the winning line.

  However, in order for a low-skilled player to enjoy the game, it is necessary to make it easy to align the symbols to some extent. On the other hand, when the result of the internal lottery is lost, it is necessary to control the rotation of the reel so that the combination is not established There is. The stop table is used to control such reel rotation. The stop positions of the left, middle, and right reels R1, R2, and R3 are determined with reference to the stop table.

  Returning to FIG. 6, the description will be continued. The transmission timing control circuit 36 and the data transmission circuit 37 shown in the figure transmit to the sub-board 30B information on the type of combination determined by the internal lottery and the stop table selected corresponding to the combination. The sub-board 30B is responsible for processing for notifying the player of predetermined information.

  Next, the input port 38 is an input interface for signals supplied from various sensors described later. On the other hand, the output port 39 is an output interface for supplying control signals to each motor and various devices.

  The main input signal generating means connected to the input port 38 and generating various input signals includes the following. The inserted medal detection sensor 41 detects a medal inserted through the medal slot 5 and generates one output pulse for one medal. Therefore, the CPU 31 can detect the number of inserted medals by counting the output pulses.

  The BET button sensor 42 detects the operation of the BET button 15. The start lever sensor 43 detects the operation of the start lever 6 and outputs a start operation signal 43a. The left / middle / right reel stop button sensors 44, 45, 46 detect the operations of the left / middle / right reel stop buttons 7a, 7b, 7c, respectively, and output stop operation signals 44a, 45a, 46a, respectively. The left / middle / right reel position detection sensors 47, 48, 49 detect the rotational positions of the left / middle / right reels R1, R2, R3, and generate detection signals 47a, 48b, 49c. The CPU 31 detects these signals and acquires the operation timing of the start lever 6, the operation timings of the reel stop buttons 7a, 7b, and 7c, and the rotation positions of the reels R1, R2, and R3.

  The right reel position detection sensor 49 includes a photocoupler 492, an amplifier, and a comparator shown in FIGS. The photocoupler 492 includes a light emitting unit and a light receiving unit. When the light receiving unit outputs a light reception signal at a level corresponding to the amount of light received, the amplifier amplifies the light reception signal. The comparator compares the output signal of the amplifier with a predetermined threshold value to generate a detection signal 49a, and outputs this as an output signal of the right reel position detection sensor 49. When the right reel R3 rotates, the light shielding piece 491 shown in FIG. 2 passes through the photocoupler 492 once per rotation. Therefore, the rotation position of the right reel R3 can be detected by the detection signal 49a. The left / middle position detection sensors 47 and 48 are configured in the same manner as the right reel position detection sensor 49.

As main means connected to the output port 39 and supplied with various output signals, there are left, middle and right reel drive motors 51, 52 and 53. The left, middle, and right reel drive motors 51, 52, and 53 are motors that respectively rotate the left, middle, and right reels R1, R2, and R3, and in this example, are constituted by stepping motors. Therefore, the CPU 31 stops the left, middle, and right reels R1, R2, and R3 by adjusting the number of pulses of the drive signals 51, 52a, and 53a supplied to the left, middle, and right reel drive motors 51, 52, and 53. It is possible to determine the position accurately.
Each of the motors 51, 52, and 53 is configured to rotate once by 400 pulses. As described above, 21 symbols are formed on each of the reels R1, R2, and R3. Of these, 20 symbols advance by 1 pulse with 19 pulses, and 1 symbol advances by 1 pulse with 20 pulses. Further, the CPU 31 counts the number of pulses supplied to each of the motors 51, 52, 53, and holds the count result as each position data MD1, MD2, MD3. The values of the position data MD1, MD2, and MD3 are reset when the detection signals 47a, 48a, and 49a become active.

  FIG. 10 is a timing chart showing the relationship between the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3. As shown in this figure, when the detection signal 49a rises from the low level to the high level at time t1, the value of the position data MD3 is reset. Time t1 is timing when the light shielding piece 491 shown in FIG. 3 passes through the photocoupler 492. At this time, as the rotational position of the right reel R3, the symbol (red 7) having the symbol number PN = 1 shown in FIG. 4 is displayed in the middle of the display window 4c. In other words, the mounting position of the light shielding piece 491 and the photocoupler 492 is determined so that the symbol is displayed in the middle of the display window 4c.

  When 20 pulses are supplied to the right reel drive motor 53 as the drive signal 53a in the period from time t1 to time t2, the right reel drive motor 53 rotates the right reel R3 by 1/21. As a result, a symbol (plum) of symbol number PN = 2 shown in FIG. 4 is displayed in the middle of the display window 4c. Thereafter, the symbols are sequentially displayed in the same manner, and when the time t3 is reached, the right reel R3 rotates once and the symbol of symbol number PN = 1 (red 7) is displayed again. Thus, since the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3 are closely related, the CPU 31 can detect the display state of the symbol based on the position data MD3.

  As for the left reel R1 and the middle reel R2, as with the right reel R3 described above, the CPU 31 can detect the display state of the symbols based on the position data MD1 and MD2.

  Next, the sub board 30B includes a CPU, a data input circuit, a clock generation circuit, a ROM, a RAM, and a liquid crystal display control circuit 60, and causes the liquid crystal display device 64 to display various effects. The sub-board 30 </ b> B controls turning on / off the left / middle / right backlights 65 to 67 and emits sound effects from the speaker 68.

  The CPU of the sub board 30B receives various commands transmitted from the main board 30A. This command includes internal lottery data ISD and the like. Based on the BB winning flag and CB winning flag of the internal lottery data, the CPU displays an animation and a character on the liquid crystal display device 64 in order to notify the player that the BB prize or CB prize has been won. In addition, a predetermined sound is emitted from the speaker 68 when the start lever 6 is operated.

<4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. 11 and 12 are flowcharts showing the operation of the CPU 31 controlling the slot machine 1 from the start to the end of one game. One game period is a period from when a bet operation is received until the next bet operation is received (until the prohibition of the bet operation is canceled).

  The CPU 31 determines whether or not the player has made a bet operation based on detection signals from the inserted medal detection sensor 41 and the BET button sensor 42 (step S11). Proceed to S12.

  In step S <b> 12, the CPU 31 determines whether the player has operated the start lever 6 based on the detection signal of the start lever sensor 43. When the player operates the start lever 6, the CPU 31 performs a process for prohibiting a bet operation (step S13). If the bet operation is prohibited, even if the player inserts a medal or operates the BET button 15 during the period until the prohibition is canceled, the acceptance is rejected.

  Next, the CPU 31 sets a prize group lottery table according to the game mode according to the first control program CP1 (step S14). Specifically, from the prize group lottery table group TBL1, a gaming state (game state) such as a normal game, an RB game in the BB, a single RB game, a BB game, a CB game, an FB game in the CB, and a single FB game Select the table according to the type. In this case, the CPU 31 refers to the RB game flag, the BB game flag, the CB game flag, and the like stored in the RAM 34, identifies the game type of the game, and selects a table based on the result.

  In the internal lottery of the FB game, there are the following two modes. In the first aspect, winning or losing is determined by lottery. However, it is preferable to make the lottery probabilities different between the FB in CB and the single FB (FB game in the normal game). The second mode does not execute internal lottery. When executing the internal lottery, if the winning prize is a predetermined prize (for example, a replay prize), the drawing range may be four frames. That is, in the FB game, it is allowed to win a predetermined prize including a prize won in the internal lottery, but the symbols constituting the winning prize are compared with the symbols constituting the predetermined prize other than the winning prize. Is preferably increased.

  Next, the CPU 31 executes an internal lottery process using the prize group lottery table TBL1 set in step S14 (step S15). That is, the type of prize group lottery table TBL1 also changes according to the type of game. Thereafter, the CPU 31 determines whether or not the RB game is in progress based on the RB game in-progress flag (step S16). When it is determined that the RB game is being played, the CPU 31 executes a winning flag setting process for the RB game (step S17). FIG. 13 shows the contents of the winning flag setting process in the RB game. In this process, the CPU 31 determines whether or not JAC has been won based on the internal lottery result (step S41). If the internal win has been made, a JAC winning flag is set (step S42). On the other hand, if the JAC is not won, the CPU 31 advances the process to step S18 shown in FIG.

  In step S18, the CPU 31 executes a reel stop data group selection process. FIG. 14 shows the processing contents. As shown in this figure, the CPU 31 determines whether or not the JAC winning flag is set (step S43). Thereafter, the CPU 31 selects the JAC stop data group if the JAC winning flag is set (step S44), and selects the loss stop data if the JAC winning flag is not set (step S45).

  Returning to FIG. If the determination condition in step S16 is negative, the CPU 31 advances the process to step S19 to determine whether or not the FB game is in progress based on the FB game in-progress flag. If it is during the FB game, the CPU 31 executes a winning flag setting process for the FB game. On the other hand, if not in the FB game, a normal winning flag setting process is executed (step S20). After these processes are completed, the CPU 31 executes a reel stop data selection process (step S22).

  FIG. 15 shows the contents of the normal winning flag setting process. The contents of the winning flag setting process are shown. Specifically, as described with reference to FIG. 8, first, the CPU 31 samples the count data CD and obtains the sampling data SD at the timing when the detection signal of the start lever sensor 43 becomes active. To do. Secondly, the CPU 31 refers to the prize group lottery table and sets a winning flag.

  As shown in FIG. 15, the CPU 31 determines whether or not the BB is won (step S50). If the BB is won, the CPU 31 sets the BB winning flag (step S51). Proceed to Next, the CPU 31 determines whether or not the CB is won (step S52). If the CB is won, the CPU 31 sets a CB winning flag (step S53). If the CB prize is not won, the process proceeds to step S54. Next, the CPU 31 determines whether or not it is a single RB win (step S54). If a single RB win is set, a single RB win flag is set (step S55). Proceed to Next, the CPU 31 determines whether or not the BB winning RB has been won (step S56). If the winning has been won, the CPU 31 sets the BB winning RB winning flag (step S57). Proceed to step S58. Next, the CPU 31 determines whether or not the bell is won (step S58). If the bell is won, a bell winning flag is set (step S59). If the bell award is not won, the process proceeds to step S60. Next, the CPU 31 determines whether or not the FB is won (step S60). If the FB is won, the CPU 31 sets the FB winning flag (step S61). If the FB prize is not won, the process proceeds to step S62. Next, the CPU 31 determines whether or not the watermelon is won (step S62). If the watermelon is won, the CPU 31 sets a watermelon winning flag (step S63). If the watermelon prize is not won, the process proceeds to step S64. Next, the CPU 31 determines whether or not the cherry is won (step S64). If the cherry is won, the CPU 31 sets a cherry winning flag (step S65). If the cherry award is not won, the process proceeds to step S66. Next, the CPU 31 determines whether or not the replay is won (step S66), and if it is won, the replay winning flag is set (step S67).

  Next, the process of setting the winning flag during the FB game will be described with reference to FIG. First, the CPU 31 determines whether or not a BB prize is won (step S72), and if a BB prize is won, a BB winning flag is set (step S73). When the BB prize is not won, or when the process of step S73 is finished, the CPU 31 determines whether or not the CB prize is won (step S74). If the CB prize is won, the CB winning flag is set. When the CB award is unsuccessful, or when the process of step S74 is completed, the CPU 31 determines whether or not a single RB award has been won (step S76).

  When the single RB award is won, the CPU 31 sets a single RB win flag (step S77) and determines whether or not a CB game is in progress (step S78). If the CB game is in progress, the CB game flag is cleared. When the single RB award is unfairly selected, or when the processing of step S78 and step S79 ends, the CPU 31 determines whether or not the FB award has been won (step S80). If the FB prize is won, the CPU 31 sets the FB winning flag (step S81). Next, the CPU 31 determines whether or not the replay is won (step S82). If it is won, the replay winning flag is set (step S83). If the replay prize is not won, the process proceeds to step S84. Next, the CPU 31 sets a bell winning flag (step S84), and then sets a cherry winning flag (step S85).

  FIG. 17 shows the processing contents of the reel stop data group selection in the base game, BB game, CB game, or FB game. The CPU 31 refers to the winning flag of the internal lottery data ISD, and receives a bell winning flag, a replay winning flag, a watermelon winning flag, a cherry winning flag, an FB winning flag, a BB winning flag, a CB winning flag, a single RB winning flag, and a BB. It is sequentially determined whether or not the medium RB winning flag is set (steps S90 to S98).

If the bell winning flag is set, the CPU 31 determines whether or not the FB game is in progress (step S99). If the FB game is in progress, the CPU 31 selects the FB bell stop data group (step S101). If the game is not in progress, the bell stop data group is selected (step S100).
Further, as a feature of the stop data group for the bell during the FB, the bell win flag and the cherry win flag are forcibly set in the win flag setting process (FB game) of FIG. Even if one or both of the cherry roles wins simultaneously, the stop control is valid in terms of stop control. Therefore, the stop data configuration allows not only the bell role but also the cherry role.
If the replay winning flag is set, the CPU 31 selects the replay stop data group (step S102), and if the watermelon winning flag is selected, the CPU 31 selects the watermelon stop data group (step S103).

  If the cherry winning flag is set, the cherry stop data group is selected (step S104). If the FB winning flag is set, the FB stop data group is selected (step S105), and the BB winning flag is set. If set, the BB stop data group is selected (step S106). If the CB win flag is set, the CB stop data group is selected (step S107). If the single RB win flag is set. A single RB stop data group is selected (step S108). If the BB RB winning flag is set, the BB RB stopping data group is selected (step S109), and the BB RB winning flag must be set. For example, stop data for losing is selected (step S110).

  Returning to FIG. When the stop data group selection process shown in step S18 or step S22 is completed, the CPU 31 executes a reel rotation start process (step S23). In this process, the CPU 31 controls the drive motor so as to start the rotation of the left, middle and right reels R1 to R3. Further, the CPU 31 starts time measurement for one game period simultaneously with the start of rotation of the left, middle and right reels R1 to R3. The CPU 31 compares the measurement time from the start of reel rotation one game before with the reference time. When the measurement time exceeds the reference time, the CPU 31 starts rotating the reel and starts measuring time for one game period. On the other hand, if the measurement time is less than the reference time, the reels start to rotate until the measurement time exceeds the reference time, and then the reels are started to rotate.

  Thereafter, the CPU 31 advances the processing to step S26 shown in FIG. 12, and the CPU 31 executes reel stop control (step S26). FIG. 18 is a flowchart showing the processing contents of the reel rotation stop processing (step S26). First, the CPU 31 determines whether or not the first button stop operation has been performed based on the stop operation signals 44a to 46a (step S120).

  When the first stop operation of the reel stop button is detected, the CPU 31 acquires the stop button number (button type) of the currently pressed reel stop buttons 7a to 7c (step S121), and the pattern immediately after the stop operation is obtained. The number PN is acquired (step S122). Specifically, the CPU 31 detects the timing at which the reel stop buttons 7a, 7b, 7c are pushed down based on the stop operation signals 44a to 46a from the reel stop button sensors 44 to 46, and the symbol number PN at the timing. To get. In this example, the stop button number “1” is assigned to the reel stop button 7a, the stop button number “2” is assigned to the reel stop button 7b, and the stop button number “3” is assigned to the reel stop button 7c.

  Next, the CPU 31 limits the usable stop data table group from the stop data table group selected in step S18 or S22 based on the stop button number, the symbol number PN, and the like (step S123). A combination of stop data tables for each operation order is specified (step S124). When there are a plurality of combinations, the CPU 31 specifies a combination of stop tables to be used by lottery or the like. When there are not a plurality of combinations, the combinations are specified. As a result, the CPU 31 determines one stop data table to be used for the first stop of the reel. (Step S125)

  Next, the CPU 31 acquires the advance frame number (moving symbol number) corresponding to the symbol number from the determined stop table (step S126), and then stops the reel that has been stopped based on the advance frame number. (Step S127).

  Next, the CPU 31 determines whether or not a second button stop operation has been performed based on the stop operation signals 44a to 46a (step 128). If there is a second button stop operation, acquisition of a stop button number ( In step S129), the symbol number is acquired (step S130), the stop table corresponding to the second stop of the reel is determined from the combination of the stop tables specified in step S124 (step S131), and the advance frame number is acquired (step S132). ) And reel stop (step S133). Thereafter, the CPU 31 determines whether or not the third button stop operation has been performed based on the stop operation signals 44a to 46a (step S134), and if there is a third button stop operation, acquires the stop button number. (Step S135) Further, a symbol number is acquired (Step S136).

  Thereafter, the CPU 31 determines whether or not the gaming state is during the FB game (step S137). If it is during the FB game, the CPU 31 executes a symbol position check process (step S138). Although detailed contents of the process will be described later, when this process ends, the CPU 31 advances the process to step S141. On the other hand, if the gaming state is not an FB game, a stop table corresponding to the third stop of the reel is determined from the combination of stop tables specified in step S124 (step S139), and the number of advance frames is acquired (step S140). And reel stop (step S141). As described above, the CPU 31 selects a stop table to be used for stop control from among a plurality of stop tables according to the type of game, the result of the internal lottery, and the order of the stop operation of the reel stop button.

  FIG. 19 shows the contents of the symbol position check process. First, the CPU 31 sets the number of temporarily advanced frames to “1” (step S300). Next, the CPU 31 confirms whether any combination of the reels that have already stopped is at the winning position corresponding to the number of medals inserted (step S301), and determines whether the bell combination is a temper. (Step S302). Here, “tempe” means a state where there is a possibility of winning a prize when the remaining one reel stops.

  When the bell combination is tempered, the CPU 31 adds the number of provisionally advanced frames and the symbol number, corrects it to an appropriate range (1 to 21), and sets it as a check symbol number (step S303). In the correction process, when the addition result value is larger than the total number of symbols (in this example, “21”), “21” is subtracted, and the subtraction result value is used as a check number. Next, the CPU 31 confirms whether or not the bell combination is won in the check symbol number of the reel band corresponding to the stop button number (step S304), and determines whether or not the bell combination is won (step S305). .

  When it is determined that the bell combination is not won, the CPU 31 determines whether or not the number of provisionally advanced frames is “0” (step S306). If the temporary advance frame number is not “0”, the CPU 31 subtracts 1 from the temporary advance frame number (step S307), and returns the process to step S303. On the other hand, when winning the bell combination or when the number of provisional advance frames is “0”, the process proceeds to step S315. That is, in the processing from step S302 to step S307, the CPU 31 determines whether or not to win the bell combination by sliding 0 frame or 1 frame.

  Next, when the determination condition in step S302 is negative, the CPU 31 determines whether or not the reel corresponding to the stop button number is the left reel R1 (step S308). When the left reel stop button 7a is pressed, the determination condition in step S302 is affirmed. In this case, as in step S303, the CPU 31 corrects the result of adding the number of provisionally advanced frames and the symbol number to an appropriate range (1 to 21) to obtain a check symbol number (step S309). Next, the CPU confirms whether or not the cherry winning combination is won in the check symbol number (step S310), and determines whether or not the cherry winning combination is won (step S311).

  When it is determined that the cherry role is not won, the CPU 31 determines whether or not the provisional advance frame number is “0” (step S312). If the provisional advance frame number is not “0”, the CPU 31 subtracts 1 from the provisional advance frame number (step S313) and returns the process to step S309. On the other hand, when winning the cherry role or when the number of temporarily advanced frames is “0”, the process proceeds to step S315. That is, in the processing from step S308 to step S313, the CPU 31 determines whether or not to win the cherry role by sliding 0 frame or 1 frame.

  Next, when the determination condition in step S308 is negative, the CPU 31 advances the processing to step S314, and determines whether or not a part other than the bell combination and cherry combination is tempered. When the determination condition is affirmed, the CPU 31 corrects the addition result of the number of provisionally advanced frames and the symbol number to an appropriate range (1 to 21) as the check symbol number, similarly to step S303 (step S303). S315). Next, the CPU 31 confirms whether any winning combination is won in the check symbol number (step S316), and determines whether or not to win any winning combination other than the bell winning role or the cherry winning role (step S317). ).

  FIG. 20 is an explanatory diagram for explaining a relative position for symbol position check, and FIG. 21 is an explanatory diagram for explaining a winning position. As shown in FIG. 20, the upper three symbol positions relative to the display frame are LU, CU and RU, the middle three symbol positions are LC, CC and RC, and the lower three symbol positions are LD. , CD and RD. Under this assumption, a symbol number PN of a symbol that stops at symbol positions LC, CC, and RC is set as a check symbol number.

  There are five winning positions in the CB game, the FB game, and the BB game, the winning positions 1 to 5 shown in FIGS. 21A to 21E, and the winning positions in the normal game are shown in FIG. There are seven ways of winning positions 1 to 7 shown in A) to (G). The ROM stores a table in which combinations of winning positions and check symbol numbers are stored in association with each combination. In step S316 described above, the CPU 31 refers to the table to determine whether or not a winning is achieved. In this example, an example in which the winning position is different between the normal game and the other games is shown, but the same winning position may be used. Also, as in this example, only in the normal game, unlike other games, by including (F) or (G) that does not form a straight line at the winning position, it is difficult to notice that the player has won the CB role. I can do it.

  If the determination condition in step S314 is negative, or if the determination condition in step S317 is affirmative, the CPU 31 advances the process to step S319, advances the provisionally advanced frame number, and stops the reel.

  If it is determined that a winning combination other than the bell role or the cherry role is won, if the CPU 31 provisional advance frame number is “1”, “1” is subtracted to set the provisional advance frame number to “0”. If the number is “0”, “1” is added to set the provisional advance frame number to “1” (step S318). Thereafter, the CPU 31 advances the provisional advance frame number and stops the reel with the frame number.

  In the reel stop control described above, on the premise of zero-frame or one-frame slip, first, it is determined whether or not a winning combination for the bell is possible, and if the winning is possible, the reel is stopped so that the winning combination is established. Next, it is determined whether or not it is possible to win the cherry role. If the winning is possible, the reel is stopped so that the bell role is established. Next, with respect to other winning combinations, when the number of provisional advance frames is set to either “0” or “1”, it is determined whether or not winning is possible. And the reel is stopped with the provisional advance frame number set to the other of “0” or “1”. If no winning is possible, the number of provisional advance frames is used as the advance frame number. Therefore, even if there is a possibility of winning a plurality of winning combinations, control is performed so that the winning combination of the bell and the cherry is won. Further, when the replay prize is won, stop control may be performed so that the replay role is preferentially stopped over the bell role and the cherry role. In this case, the winning combination of the bell and cherry is not possible.

  Thus, in the reel stop control, the CPU 31 detects the timing at which the reel stop buttons 7a, 7b, 7c are operated as the stop operation timing (steps S120, S128, S134), and the variable display of each reel R1 to R3 is performed. Control is performed so that the display stop timing to stop is delayed from the stop operation timing. Then, in the next FB game that won the FB prize, the CPU 31 forcibly selects the winning flag so as to allow a stop mode corresponding to some prizes among a plurality of prizes regardless of the result of the internal lottery. Control to set. In this case, the advance frame number range is from 0 to 4 frames in games other than during the FB game, whereas the allowable range of the advance frame number in at least one reel is 0 or 1 frame.

  Returning to FIG. When the reel stop control described above is completed, the CPU 31 determines whether or not the replay winning is made (step S27). If the replay winning is made, the replay winning flag is cleared and the process returns to step S12. At this time, an automatic bet is made. On the other hand, if the replay prize is not won, the CPU 31 advances the process to step S29 and refers to the flag indicating the gaming state to determine whether the game is in the normal / BB / CB / FB game or in the RB game. Determine if there is.

  And CPU31 performs each winning determination process according to a game state (step S30, S31). FIG. 22 shows the contents of the winning determination process during the normal / BB / CB / FB game. In this process, by comparing the symbols on each active line of each stopped reel with the combination of symbols assigned to each award, it is sequentially determined whether or not a watermelon, bell, or cherry award was won. Determination is made (steps S150 to S152), and each part is controlled to pay out the number of medals corresponding to the winning prize with reference to the winning symbol combination table TBL3 (steps S153 to S155).

  Next, the CPU 31 determines whether or not it is a single RB win (step S156). If it is a single RB win, the medal is paid out (step S157), and further an RB game start process is executed (step S158). . FIG. 23 shows the contents of the RB start process. In this process, the CPU 31 sets an RB game flag (step S176), and sets the number of JAC winnings (step S177). For example, 8 times. Next, the CPU 31 sets the number of JAC games (step S178). For example, 12 times.

  If the determination condition is negative in step S156 of FIG. 22, the CPU 31 advances the process to step S159 to determine whether or not the BB winning is in BB. Specifically, the determination condition is affirmed when the BB game flag is set and the RB winning flag is set, and the determination condition is denied otherwise. If the determination condition is affirmed, the CPU 31 pays out medals assigned to the RB award (step S160) and executes an RB start process (step S161). Since the RB start process in step S161 is the same as that in step S158, description thereof is omitted.

  On the other hand, if the determination condition in step S159 is negative, the CPU 31 advances the process to step S162 to determine whether or not the BB game is in progress. Specifically, the determination condition is affirmed when the BB game flag is set, and the determination condition is denied otherwise. If the determination condition is affirmed, the CPU 31 executes a BB game end determination process (step S163).

  FIG. 24 shows the contents of the BB game end determination process. In this process, the CPU 31 determines whether or not a medal has been paid out (step S180). If there has been a medal payout, the CPU 31 adds the acquired number of games to the acquired number of BB games (step S181). If no medal is paid out in the game, the process of step S181 is omitted, and when the process of step S181 is completed, the CPU 31 advances the process to step S182 to determine whether or not the number of acquired medals exceeds a predetermined number. Determine. Here, the predetermined number X1 is X1 = Y1 where Y1 is the maximum number of sheets allowed for the entire BB game and Z1 is the maximum number of sheets that can be acquired in one game in the BB game (next one game). -Z1. In this example, the maximum number of coins allowed in the entire BB game is 465, and the maximum number of medals that can be earned in one game in the BB game is 15. Therefore, 450 sheets is a predetermined number.

  If the number of acquired medals exceeds 450 and the determination condition in step S182 is negative, the CPU 31 advances the process to step S183, and displays the number of acquired medals during the BB game (step S183). On the other hand, when the number of acquired medals exceeds 450, the BB game flag is cleared (step S184), and it is further determined with reference to the RB game flag whether the RB game is being played (step S185). ) If the RB game is in progress, the RB game flag is cleared (step S186). That is, when the acquired number exceeds the predetermined number, the BB game is ended. As a result, it is possible to make adjustments so as not to exceed the maximum number of sheets allowed for the entire BB game. In this embodiment, the calculation of the number of acquired medals, which is the BB end condition, is performed for all medals acquired during the BB game. However, the number of medals acquired during the RB in the BB may be limited. Good.

  Returning to FIG. If it is determined in step S162 that the BB game is not being played, the CPU 31 advances the process to step S164 to determine whether or not a BB prize has been won. If the BB prize is won, a predetermined number of medals are paid out (step S165), and the BB game start process is executed (step S166). FIG. 25 shows details of the BB game start process. As shown in the figure, the CPU 31 sets a flag during the BB game (step S187), and clears the acquisition number count during the BB game (step S188). Thereby, the accumulation of the number of acquisitions from the next game is executed.

  On the other hand, if it is determined in step S164 that the game does not correspond to the BB winning, the CPU 31 advances the process to step S167 to determine whether or not the CB game is in progress. Specifically, the determination condition is affirmed when the CB game flag is set, and the determination condition is denied otherwise. If the determination condition is affirmed, the CPU 31 executes a CB game end determination process (step S168).

  FIG. 26 shows details of the CB game end processing. As shown in the figure, the CPU 31 determines whether or not a medal has been paid out (step S190). If a medal has been paid out, the acquired number of games in the FB game is added (step S191). ). If no medals are paid out in the game, the process of step S191 is omitted. When the process of step S191 is completed, the CPU 31 advances the process to step S192 to determine whether the number of acquired medals exceeds a predetermined number. Determine. Here, the predetermined number X2 is X2 = Y2 where Y2 is the maximum number of sheets allowed for the entire CB game and Z2 is the maximum number of sheets that can be acquired in one game in the CB game (next one game). -Z2. In this example, the maximum number of acquisitions allowed in the entire CB game is 253, and the maximum acquisition number that can be acquired in one game in the CB game is 15. Accordingly, 238 sheets are the predetermined number.

  If the number of acquired medals exceeds 238 and the determination condition in step S192 is negative, the CPU 31 advances the process to step S193, and displays the number of acquired medals during the CB game (step S193). On the other hand, if the number of acquired medals exceeds 238, the CB game flag is cleared (step S194), and it is further determined with reference to the FB game flag whether the FB game is in progress (step S195). ) If the FB game is in progress, the FB game flag is cleared (step S196). That is, when the acquired number exceeds the predetermined number, the CB game is ended. As a result, it is possible to make adjustments so as not to exceed the maximum number allowed for the entire CB game. In this embodiment, the calculation of the number of acquired medals, which is a CB end condition, is performed for all medals acquired during the CB game. However, the calculation is limited to the number of medals acquired during the FB in the CB. Good.

  Returning to FIG. If it is determined in step S167 that the CB game is not being played, the CPU 31 advances the process to step S168 to determine whether or not a CB winning is achieved. If the CB prize is won, the CB game start process is executed without paying out medals (step S170). FIG. 27 shows details of the CB game start process. First, the CPU 31 sets a CB game flag (step S197), and clears the acquired number count during the CB game (step S198). Thereby, the accumulation of the number of acquisitions from the next game is executed.

  If the determination condition in step S169 is negative, the CPU 31 advances the process to step S171 to determine whether or not an FB game is in progress. If it is during the FB game, the CPU 31 clears the FB game flag (step S172). When the process of step S172 ends or when the determination condition of step S171 is denied, the CPU 31 determines whether or not the FB winning is achieved (step S173).

  If the FB prize is won, the CPU 31 pays out medals assigned to the FB prize (step S175), and sets the FB game flag. If the process in step S175 ends, or if it is determined in step S173 that it is not an FB winning, the process ends.

  In the above-described winning determination process, when the CPU 31 detects that each prize has been won, the CPU 31 generates winning information indicating the winning prize and transmits it to the sub-board 30B. The sub CPU provided on the sub board 30B causes the liquid crystal display device 64 to display an effect image based on the winning information. However, when the winning information indicates the CB prize, the effect is not executed. In addition, the sub CPU executes the same effects (including no effects) as the normal game in at least the first game of the CB game. That is, the sub-board 30B and the liquid crystal display device 64 notify the player that the BB prize has been won when the prize information indicates the BB prize, and that the CB prize has been won when the prize information indicates the CB prize. It functions as a notification means that does not notify the player.

  Next, the winning determination process (step S31 in FIG. 12) in the RB game will be described. FIG. 28 shows a detailed flowchart of the winning determination process in the RB game. First, the CPU 31 determines whether or not it is a JAC prize (step S200). If it is a JAC prize, a predetermined number of medals are paid out (step S201). It is determined whether the medal payout process ends, or if it is not a JAC prize, it is during the RB game (step S202). If the RB game flag is set, the CPU 31 determines that the RB game is being played, advances the process to step S203, and executes an RB game end determination process.

  FIG. 29 is a flowchart showing details of the RB game end determination process. As shown in the figure, the CPU 31 first determines whether or not it is a JAC prize (step S210). If it is a JAC prize, the JAC prize number is subtracted by "1" (step S211), and the number of JAC prizes is further increased. Is determined to be “0” (step S212). If the JAC winning number is “0”, the CPU 31 clears the RB game flag (step S217). On the other hand, if the number of JAC wins is not “0”, the CPU 31 displays the remaining number of JAC wins (step S213) and subtracts the number of JAC games by “1” (step S214). If the JAC prize is not won, the CPU 31 skips the processing from step S211 to step S213, and proceeds from step S210 to step S214. Thereafter, the CPU 31 determines whether or not the remaining number of JAC games is “0” (step S214). If it is “0”, the RB game flag is cleared (step S217), while it must be “0”. For example, the remaining number of JAC games is displayed (step S216).

  The description returns to FIG. When the above-described RB game end determination process ends, or when the RB game flag is cleared and the determination condition in step S202 is negative, the CPU 31 sets whether the BB game is in progress or not. The determination is made with reference to (step S204). When the BB game flag is set, the CPU 31 determines that the BB game is being played, advances the process to step S205, and executes a BB game end determination process. On the other hand, if the BB game flag is cleared, the CPU 31 determines that the BB game is not in progress and ends the RB game winning determination process. Since the BB game end determination processing has already been described with reference to FIG. 24, description thereof is omitted.

  Returning to FIG. When the winning determination process ends (steps S30 and S31), the CPU 31 executes a one-game end process (step S32), and then releases the BET operation (step S33).

  Next, one game end processing will be described. 30 and 31 are flowcharts showing the processing contents of one game end processing. The CPU 31 sequentially determines whether or not the replay winning flag, the watermelon winning flag, the bell winning flag, and the cherry winning flag are set (steps S240 to S243), and clears the set winning flags (steps S245 to S248). ). Next, the CPU 31 determines whether or not the BB winning flag is set (step S249). If the BB winning flag is set, the CPU 31 further determines whether or not the BB prize is won (step S250). If the BB winning flag is won, the BB winning flag is cleared (step S251). On the other hand, if no prize has been won, it is carried over to the next game without clearing the BB winning flag.

  Next, the CPU 31 determines whether or not the CB winning flag is set (step S252). If the CB winning flag is set, the CPU 31 further determines whether or not a CB prize has been won (step S253), and if it has won, the CB winning flag is cleared (step S254). On the other hand, if it is not won, it is carried over to the next game without clearing the CB winning flag.

  Next, the CPU 31 advances the processing to step S255 shown in FIG. 41, and determines whether or not the single RB winning flag is set (step S255). If the single RB winning flag is set, the CPU 31 further determines whether or not the RB prize has been won (step S256). If the single RB winning flag has been won, the single RB winning flag is cleared (step S257). . On the other hand, if no winning is made, it is carried over to the next game without clearing the single RB winning flag.

  Thereafter, the CPU 31 sequentially determines whether the RB winning flag during BB, the FB winning flag during CB, and the JAC winning flag are set (steps S258 to 260), and clears the set winning flag (step S261). ~ S263).
