Description

  The present invention relates to a slot machine that generates an RT state in which the internal winning probability of a replay combination is increased.

  Conventionally, a slot machine equipped with an RT function for generating an RT state in which the internal winning probability of a replay role is increased is known. Various types of RT functions have been proposed and commercialized so far. The most popular RT function type is a so-called loop RT function that shifts to an RT state of a fixed number of games when a specific RT transition symbol is stopped and displayed in a normal state (for example, , See Patent Document 1).

  Further, in recent years, a plurality of types of RT transition symbols are set, and a type in which a different number of fixed games is set for each type of RT transition symbol, or a stop display of RT transition symbols can be intentionally avoided by the player. New types of loop-type RT functions such as types have been proposed.

  However, the conventional slot machine has the following problems. That is, if the RT function becomes complicated as described above, the gaming characteristics of the slot machine may not be sufficiently grasped only by conventional game data such as the number of bonus winnings and the number of difference medals.

JP 2006-340866 A

  The present invention has been made in view of the above-described conventional problems, and has a case where a so-called loop RT function is installed and the player can intentionally avoid the stop display of the RT transition symbol. With regard to the slot machine thus provided, it is an object of the present invention to provide a slot machine in which a player can sufficiently grasp game characteristics.

The present invention includes a symbol variation display means for variably displaying a plurality of types of symbols according to a predetermined arrangement in a plurality of symbol display areas,
Game start operation means operated by the player to start the game with the game medium inserted;
An internal lottery means for executing an internal lottery for determining an internal winning combination from a plurality of types of combinations including a replay combination in response to an operation of the game start operation means;
A stop operation means operated by a player to stop the display of the variation of the symbol by the symbol variation display means;
In response to an operation of the stop operation means, a display control means for drawing a symbol corresponding to an internal winning combination within a predetermined pull-in range and displaying the stop in the symbol display area;
Winning determination means for determining whether a combination of symbols stopped and displayed in each symbol display area of the symbol variation display means is a predetermined winning symbol;
Profit granting means for granting a player a profit corresponding to the winning symbol when it is determined that the winning symbol is determined by the winning determining unit;
Specific game state generating means for generating a specific game state;
First RT generating means for generating a first RT state in which the internal winning probability of the replay role is higher than the specific gaming state when the first RT transition symbol is stopped and displayed by the symbol variation display means in the specific gaming state;
When the second RT transition symbol is stopped and displayed in the specific gaming state, the second RT has a higher internal winning probability of the replay role than the specific gaming state and a higher degree of advantage on the player side than the first RT state. Second RT generating means for generating a state;
When the third RT transition symbol is stopped and displayed in the specific gaming state, the internal winning probability of the replay role is lower than that in the first RT state and the second RT state, and the player is more advantageous than the first RT state. A third RT generating means for generating a third RT state having a low degree;
First RT avoiding means for avoiding the stop display of the first RT transition symbol when a specific stop operation is performed by the player in the game in which the first RT trigger corresponding to the first RT transition symbol is determined as the internal winning combination In a slot machine including
First RT winning number counting means for counting, as the first RT winning number, the number of times the first RT opportunity is determined as an internal winning combination in the specific gaming state;
First RT avoidance counting means for counting the number of times the first RT avoidance means avoids the stop display of the first RT transition symbol in the specific gaming state as the first RT avoidance count;
A slot machine comprising: display means for displaying the first RT winning count and the first RT avoidance count (Claim 1).

  In the game of the slot machine of the present invention, at least the first RT state, the second RT state, and the third RT state are set as gaming states that can be shifted from the specific gaming state. The first RT state, the second RT state, and the third RT state may occur in response to a stop display of the first RT transition symbol, the second RT transition symbol, and the third RT transition symbol in the specific gaming state. The order of the degree of advantage of these three types of RT states is the third RT state <the first RT state <the second RT state.

  The slot machine includes the first RT avoiding means for avoiding a stop display of the first RT transition symbol in a game in which a combination corresponding to the first RT transition symbol is determined as an internal winning combination. The first RT avoiding means avoids the stop display of the first RT transition symbol when the specific stop operation is performed. In the player, even if the first RT transition symbol can be stopped and displayed, the transition to the first RT state can be avoided with high certainty by performing the specific stop operation.

  In the slot machine, the first RT transition symbol is stopped by the first RT winning number counting means for counting the first RT winning number for which the first RT trigger is determined as an internal winning combination, and the first RT avoiding means displays the stop indication of the first RT transition symbol. The first RT avoidance counting means for counting the first RT avoidance count that has been avoided, and the display means for displaying the first RT winning count and the first RT avoidance count.

  The player of the slot machine according to the present invention actually determines how many times the first RT trigger is actually won in accordance with the display of the first RT winning number and the first RT avoiding number on the display means, You can objectively understand whether you have won a prize. Then, by comparing the grasped result with the actual game result (game appearance), it is possible to determine the effect of intentionally avoiding the winning of the first RT opportunity.

  As described above, the slot machine of the present invention is a slot machine in which a so-called loop-type RT function is mounted and a case where the player can intentionally avoid the stop display of the RT transition symbol is set. Thus, it is a slot machine with excellent characteristics that makes it easy for a player to grasp game characteristics.

The slot machine of the present invention may be a slot machine in a narrow sense using medals and coins as game media, or a parrot (R) using pachinko balls as game media.
Further, in the specific gaming state, the second RT transition symbol is stopped and displayed in the game after the first RT avoiding means avoids the stop display of the first RT transition symbol, and the state shifts from the specific gaming state to the second RT state. Number of successes after avoidance,
The number of times the third RT transition symbol is stopped and displayed from the specific gaming state to the third RT state in the game after the first RT avoiding means avoids the stop display of the first RT transition symbol in the specific gaming state. The number of falls after avoidance,
And the number of times that the first RT transition symbol is stopped and displayed in the game after the first RT avoiding means avoids the stop display of the first RT transition symbol in the specific gaming state, and the transition to the first RT state from the specific gaming state. A post-avoidance frequency counting means for counting at least one of the post-avoidance waste times
Preferably, the display means can display the number of times counted by the post-avoidance number counting means (claim 2).

  In this case, according to the number of times counted by the post-avoidance count counting means, it becomes possible to grasp the tendency of the game state transition after avoiding the winning of the first RT opportunity. In particular, when a large value is displayed as the number of successes after avoidance, the player's satisfaction can be further enhanced.

In the first RT generating means, the first RT game number is set as the upper limit of the continuous game number,
In the second RT generating means, a second RT game number larger than the first RT game number is set as an upper limit of the continuous game number,
In the third RT generating means, it is preferable that a third RT game number larger than the first RT game number is set as an upper limit of the number of continuous games (claim 3).

  In this case, the second RT state that is advantageous to the player side continues for a long time, while the third RT state that is not preferable for the player also continues for a long time. It is possible to set a large disparity of advantages and disadvantages between the transition from the specific gaming state to the second RT state and the transition to the third RT state, thereby enhancing the interest of the game.

Further, the specific gaming state generating means ends the specific gaming state when the number of continuing games in the specific gaming state reaches a predetermined number of games,
Preferably, the third RT generating means generates the third RT state when the specific gaming state is ended in accordance with the digestion of the predetermined number of games (claim 4).

  In this case, if the specific gaming state continues to some extent, the state automatically falls to the third RT state, so the determination of whether or not to win the first RT trigger role should be made more severe. obtain. Players will be able to enjoy a game full of tension.

Further, the specific gaming state is a state in which transition to other gaming states including the first RT state, the second RT state, and the third RT state is possible, and the expected value of the number of continued games is the first RT game. The number is preferably less than the number (claim 5).
The expected value of the continuous game in the specific gaming state is the number of continuous games calculated based on the probability that the first RT transition symbol, the second RT transition symbol, and the third RT transition symbol can be stopped and displayed. For example, if the expected value of the number of continuing games in the specific game state is 5 games, the most likely transition to the first RT state to the third RT state is after the specific game state has been consumed for 5 games. It will be expensive.

  As described above, when the expected value of the number of continued games in the specific gaming state is smaller than the number of first RT games, the duration of the specific gaming state is a relatively short period. The specific gaming state may be a provisional gaming state that can shift to the first RT state, the second RT state, the third RT state, or the like. Therefore, shifting from the specific gaming state to a more advantageous gaming state can be a point for advantageously proceeding with the game in the slot machine.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example relates to a slot machine 1 having a so-called loop RT function that generates an RT state with a fixed number of games when a predetermined RT transition symbol is stopped and displayed in a normal state (specific game state). . The contents will be described with reference to FIGS.

  First, the external configuration of the slot machine 1 of this example will be described with reference to FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 is configured by arranging a liquid crystal display unit 53, a pair of left and right speakers 520, and a decorative lamp unit 56 on the upper side of the symbol display window 11. A base 100 that forms the base of the slot machine 1 is formed below the symbol display window 11. On the right side of the symbol display window 11, a payout number display unit 551 for displaying the number of medal payouts and a credit number display unit 552 for displaying the number of credits are arranged. A data display button 67 for switching the display of the liquid crystal display unit 53 is arranged on the right side of the liquid crystal display unit 53.

  The base portion 100 is formed so as to protrude relative to the symbol display window 11 located behind the player. The base unit 100 has a table-like operation surface 14 at the upper end adjacent to the symbol display window 11, a medal tray 15 for paying out medals (game media) at the lower end, and the operation surface 14 and the medal tray 15. And an operation panel 13.

  On the operation surface 14, a bet button 64 for inserting a medal credited (stored) by a credit function, a settlement button 65 for paying out a credited medal, and a medal insertion for directly inserting a medal A mouth 630 is arranged. The operation panel 13 is provided with a start lever 62 (game start operation means) for starting the symbol fluctuation of the reel 21 and a stop button 61 (stop operation means) for stopping the symbol fluctuation.

  The bet button 64 is a button for inserting three medals out of the credited medals. The bet button 64 generates a 3-bet signal indicating the insertion number 3. However, when the remaining credit is 2 or 1, a 2-bet signal or 1-bet signal is generated, and when the credit is zero, a bet signal is not generated.

  The start lever 62 is an operation lever that generates a game start signal that is a control signal for the reel 21 in accordance with the player's operation. In the slot machine 1, the start lever 62 is set to the valid state on the premise that a medal is inserted directly or a medal is inserted by operating the bet button 64. When Replay 1 to Replay 3 wins, a state where a medal is directly inserted or a medal is automatically inserted even if no betting operation is performed, that is, a state where the next game can be started can be set. .

  The stop button 61 is an operation button that generates a variable stop signal that is a control signal for the reel 21 in accordance with the player's operation. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

  As shown in FIG. 1, the symbol display window 11 is a display window including symbol display areas 110L, C, and R. Each of the symbol display areas 110L, C, and R is a symbol display area for three symbols. In the entire symbol display window 11, symbol display regions for nine symbols arranged in a two-dimensional matrix composed of three rows and three columns are formed. The symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side.

  In the symbol display area in which nine symbols 20 are arranged in a two-dimensional matrix, winning lines 211 to 215 that are the arrangement direction of winning symbols to be awarded are set. As shown in FIG. 2, the winning lines in this example are diagonal winning lines 212 and 213, a horizontal middle winning line 211, a V-shaped winning line 214, and an inverted V-shaped winning line 215. It consists of 5 lines consisting of All three symbols displayed in the symbol display areas 110L and 110R can be positioned on the winning line, while in the symbol display area 110C, only one middle symbol of the three symbols is positioned on the winning line.

  Reels 21L, C, and R constituting the symbol variation display means 2 are arranged on the back side of the symbol display areas 110L, C, and R, respectively. The reels 21L, 21C, and 21R are rotary reels having a cylindrical shape and 21 symbols 20 arranged on the outer peripheral surface thereof at a substantially constant interval. The symbol arrangement on each reel 21L, C, R will be described later with reference to FIG. Further, as the reel 21, an image-type reel that variably displays a symbol on the liquid crystal display can be adopted instead of the rotary reel of this example.

As shown in FIG. 1, the speaker 520 and the decorative lamp unit 56 are rendering means for rendering a game with sound or light.
The payout number display unit 551 is a display unit that displays the number of medals paid out at the time of winning a prize.
The credit number display unit 552 is a display unit that displays the number of medals credited (stored) by the credit function.

  The liquid crystal display unit 53 includes a liquid crystal display. The liquid crystal display unit 53 includes replay 1 notification screen 531 (FIG. 8), RT1 state / RT2 state entry notification screen 532 (FIG. 9), small role notification screen 533 (FIG. 10) and other game effect screens, data display screen 671. A data display screen such as 672 (FIGS. 11 and 12) can be displayed. The game effect screen and the data display screen can be switched according to the operation of the data display button 67. The contents of each screen will be described later.

Next, the role of the slot machine 1 of this example, the outline | summary of gameability, and a symbol arrangement | sequence are demonstrated.
In the slot machine 1, as shown in FIG. 3, a combination, an internal winning combination, and a winning combination are set. As the combination, there are two types of bonus combinations, five types of small combinations such as a 12-sheet combination and a 5-sheet combination, and three types of replay combinations. In the figure, the name of each combination is shown in the left column, a winning symbol that is a combination of symbols 20 corresponding to each symbol is shown in the middle column, and profits given to the player in accordance with winning are shown in the right column.

  In the slot machine 1, the winning combination internally by the internal lottery means 41 becomes the internal winning combination. When the winning symbol corresponding to the internal winning combination is established along the winning line, the winning combination becomes the winning combination. In this example, replay 1 to replay 3 are set as three types of replay combinations, and REG1 and REG2 are set as two types of bonus combinations. In this example, the winning symbol (first RT transition symbol) of Replay 1, the winning symbol (second RT transition symbol) of Replay 2, and the winning symbol (third RT transition symbol) of 12 sheets are RT transition symbols. The replay 3 is a normal replay role that generates only the replay game.

  In the game of the slot machine 1, as shown in FIG. 4, the RT1 state, the RT2 state, and the RT3 state can occur according to the replay 1, the replay 2, and the 12-piece winning combination in the normal state. In the RT1 state (first RT state) corresponding to the winning of Replay 1, the first RT game number that is the upper limit of the number of continuing games is fixed to 30 games, and the RP probability that is the internal winning probability of the replay role is 1 / 1.3 RT state. The RT2 state (second RT state) corresponding to the winning of Replay 2 is an RT state in which the number of second RT games is fixed to 300 games and the RP probability is 1 / 1.3. The RT3 state (third RT state) corresponding to the 12-game winning combination is an RT state in which the third RT game number is fixed to 700 games and the RP probability is 1 / 7.3. The RT1 state, the RT2 state, and the RT3 state can be continued until the number of each RT game is consumed unless the bonus combination is won internally.

  In the normal state and the RT3 state, the payout rate (number of payouts / injections) is about 50%, while the payout rate in the RT1 state and the RT2 state is set to about 130%. Note that the payout rate in the REG state (bonus state) generated in response to winning of REG1 and REG2 which are bonus combinations is about 450%. Of the three types of RT states generated by the slot machine 1, the RT2 state, which has more RT games than the RT1 state, is the most advantageous. The RT3 state, which can last for a very long time, is the most disadvantageous. If the player can win the replay 2 during the normal state, the most advantageous RT2 state can be generated. On the other hand, if the 12 winning combination wins, the disadvantageous RT3 state continues for a long time. The normal state in the slot machine 1 is a chance time that can be shifted to an advantageous RT2 state, although it may fall into an unfavorable RT3 state.

  In the game of the slot machine 1, when the replay 1 wins the internal winning in the normal state, the replay 3 always wins simultaneously, and when the replay 1 wins the internal winning, the fact is notified. The winning symbol of Replay 1 is “RR-2 ball cherry”, while the winning symbol of Replay 3 is “R—R—R”, and only the corresponding symbol of the right reel 21R is different. When simultaneous winning of Replay 1 and Replay 3 occurs, one of them can win according to the stop operation order. When the player is notified of the internal winning of Replay 1, whether to avoid Replay 1 winning in order to win Replay 2 or whether to replay 1 to avoid winning 12 Can be selected. If the winning of Replay 1 is avoided, it is possible to leave a possibility that a more advantageous RT2 state will occur in accordance with the winning of Replay 2 thereafter.

  On each reel 21L, C, R, symbols are arranged as shown in FIG. In the left reel 21L and the middle reel 21C, R which is a corresponding pattern of the replay 1 and the replay 3 is arranged so that it can be pulled in and stopped on the winning line regardless of the timing of the stop operation by pull-in control by the display control means 43 described later. Has been. Further, in the right reel 21R, the correspondence of the two-ball cherry and the replay 3 which are the corresponding symbols of the replay 1 so that it can be drawn on the winning line and stopped regardless of the timing of the stop operation by the pull-in control by the display control means 43 described later. R which is a design is arranged. In the slot machine 1, when the replay 1 and the replay 3 are simultaneously won, the replay 1 can win if the replay 1 is stopped from the left reel 21L, and the replay 3 can win if the stop is stopped from the right reel 21R.

  Next, the electrical configuration of the slot machine 1 of this example will be described with reference to FIG. For the control unit 3 that controls the overall operation of the slot machine 1, in addition to the above-described configuration, the inserted medal detection unit 63 that detects medals inserted directly through the medal insertion slot 630 and the reel 21 together with the symbol variation display Various display units 55 including a reel driving unit 22 constituting the means 2, a reference position detecting unit 66 for detecting the rotational position of the reel 21, a medal paying unit 54 for paying out medals, a payout number display unit 551 and a credit number display unit 552. A set value operation unit 68 for setting a set value representing the player's advantage degree, an audio output unit 52 for controlling the speaker 520, and the like are electrically connected.

  The inserted medal detection unit 63 is a detection unit for a medal inserted directly from the medal insertion port 630. The inserted medal detection unit 63 outputs an insert signal every time a medal is inserted from the medal insertion slot 630. In the slot machine 1 of this example, the start lever 62 is set to an effective state when three medals are inserted in response to direct insertion of medals, operation of the bet button 64, or winning of replays 1 to 3. Then, a new game can be started.

The reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is means for rotating the reel 21 by the rotational driving force of the stepping motor.
The reference position detection unit 66 is a detection unit that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.

The medal payout unit 54 is a payout unit that pays out a predetermined number (see FIG. 3) of medals to the medal tray 15 in accordance with winning.
The set value operation unit 68 is an operation unit for changing set values of 6 stages having different winning probabilities such as bonus combinations using the setting key 680.

  As shown in FIG. 6, the control unit 3 includes a CPU 31, a ROM 33 and a RAM 34 as memory means, an I / O unit 32 as an input / output interface, a random number generation unit 350 that generates random numbers, and a random number for internal lottery. And a random number extraction unit 35 for extracting. The CPU 31 executes a software program read from the ROM 33 to thereby display a winning determination means 44 for determining a winning symbol, a display control means 43 for controlling the reel 21, an internal lottery means 41 for lottering an internal winning combination, and an internal winning flag. A flag control means 42 for controlling, a profit giving means 45 for giving a profit according to a winning, a specific game state generating means 461 for generating a normal state, a bonus state generating means 462 for generating a bonus state, and a first RT for generating an RT1 state The generating means 471, the second RT generating means 472 for generating the RT2 state, the third RT generating means 473 for generating the RT3 state, the first RT avoiding means 48 for avoiding the stop display of the winning symbol of the replay 1 which is the first RT transition symbol, the replay 1st RT winning number counting means 4 for counting the number of internal winnings of 1 1. First RT avoidance counting means 492 that counts the number of times the Replay 1 winning is avoided, Count after avoidance counting means 493 that counts the number of successful times after avoidance after avoiding the winning of Replay 1, and counts game data in the slot machine 1 Each function is realized as a game data counting means 494 to display and display means 40 for displaying game data relating to the normal state.

  The ROM 33 which is a memory means stores a winning random number table used by the internal lottery means 41 for the lottery of the internal winning combination and a reel control table (not shown) used by the display control means 43 for the stop control of the reel 21. A reel control table (not shown) is a table for defining symbols that can be stopped on the winning lines 211 to 215.

  As shown in FIG. 7, the winning random number table for lottering the internal winning combination is a data table in which the range of the winning random number for each combination is defined among the random numbers for lottery from 0 to 65535. As shown in FIG. 7, the winning random number table for internal lottery includes the winning random number table A applied to the normal state, the winning random number table B applied to the RT1 state and the RT2 state, and the winning random number table applied to the RT3 state. There is a winning random number table D applied to the C and REG states.

  In the winning random number table A, winning random numbers of REG1, REG2, small role, and replays 1 to 3 are defined. In the winning random number table B, all of the winning random numbers of Replay 1 and 2 in the winning random number table A and most of the lost random numbers are changed to winning random numbers of Replay 3. Therefore, in the RT1 state and the RT2 state to which the winning random number table B is applied, the internal winning probability of the replay 3 is high, but the possibility that the replays 1 and 2 are internally won is zero.

  In the winning random number table C, all of the winning random numbers for Replay 1 and Replay 2 in the winning random number table A are changed to winning random numbers for Replay 3. Therefore, in the RT3 state to which the winning random number table C is applied, the internal winning probability of the replay combination is the same as that in the normal state, while the possibility that the replay 1 and the replay 2 are internally won is zero. In the winning random number table D, most of the random numbers for lottery from 0 to 65535 are changed to winning random numbers of three. In the REG state to which the winning random number table D is applied, three winning combinations can be internally won with high probability. In this example, in all of the winning random number tables A to C, a simultaneous winning random number is set in which the 12 RT combination whose 1st RT transition symbol is the winning symbol and the 1 winning combination (1 winning combination 1 or 2) are simultaneously selected. Has been.

  As shown in FIG. 6, the random number generator 350 is a part that generates random numbers belonging to a predetermined integer range. The random number generated by the random number generator 350 includes a random number in the integer range of 0 to 65535 for drawing the internal winning combination.

  The random number extraction unit 35 is a part for extracting lottery random numbers. The random number extraction unit 35 extracts lottery random numbers from the random numbers generated by the random number generation unit 350. As the random numbers for lottery extracted by the random number extraction unit 35, there are random numbers in the range of 0 to 65535 for the internal lottery means 41 to draw the internal winning combination. The random number extraction unit 35 extracts a random number for lottery for drawing an internal winning combination in response to a game start signal corresponding to the operation of the start lever 62.

  The internal lottery means 41 is a means for determining an internal winning combination by internal lottery. The internal lottery means 41 collates the lottery random numbers against the winning random numbers of each combination specified in the winning random number table (FIG. 7) to determine the internal winning combination. The internal lottery means 41 selectively uses one of the winning random number tables shown in FIG. 7 according to the gaming state.

  The flag control means 42 is a means for controlling an internal winning flag corresponding to the internal winning combination. The flag control means 42 sets the internal winning flag corresponding to the internal winning combination determined by the internal lottery means 41 to the ON state. The internal winning flags of other combinations other than the bonus winning combination are reset to the off state (zero) before starting the next game, regardless of whether or not the game in which the internal winning flag is established is won for the first time. Therefore, if each combination other than the bonus combination is not won in the internal winning game, all will be missed. On the other hand, regarding the bonus flag which is the internal winning flag of the bonus combination, the established state of the internal winning flag is sequentially carried over to the next game until winning, and is reset to the off state according to winning.

  The display control means 43 is means for starting the symbol variation of the reel 21 in response to the game start signal and stopping the symbol variation of the reel 21 in response to the variation stop signal. The display control means 43 inputs a control pulse to the stepping motor constituting the reel driving unit 22 and rotates the stepping motor by one step for each pulse. The display control means 43 counts the number of control pulses input to the reel drive unit 22, that is, the number of steps rotated by the stepping motor. In particular, the display control means 43 of this example counts the number of steps generated after the most recent detection signal by resetting the number of steps to zero each time the detection signal of the reference position piece of each reel 21 is fetched.

  The display control means 43 is a means for executing so-called pull-in control in which symbols within a predetermined pull-in range determined by rules (rules for game machine authorization and type verification, etc.) are stopped on the winning line. In this example, as described above, a range corresponding to four symbols is set as the pull-in range. The display control means 43 determines the stop position by comparing the number of steps when the change stop signal is taken in with the reel control table. The display control means 43 pulls the symbol corresponding to the determined stop position and stops the reel 21.

  The winning determination unit 44 is a unit that determines whether or not a winning has occurred based on a combination of symbols that the three reels 21L, 21C, 21R stop display. Specifically, the winning determination means 44 determines the winning combination according to the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means 44 takes in the number of steps of each stepping motor (reel driving unit 22) corresponding to each reel 21L, C, R after each reel 21L, C, R stops.
