Description

  The present invention relates to a gaming machine represented by a pachinko gaming machine, a slot machine or the like.

  In gaming machines such as pachinko gaming machines and slot machines, techniques related to probability-variable pachinko gaming machines in which the probability of jackpots fluctuating has been proposed. This probability fluctuation is a so-called jackpot symbol, which is a jackpot lottery for a special symbol (a jackpot symbol for a liquid crystal display etc., which is a jackpot when the same number or pattern, etc. are stopped on the same line). A random lottery of probability variation is separately performed, and if this is won, the jackpot probability of the next special symbol is varied (for example, the jackpot probability of the special symbol is increased 10 times during the probability variation, etc.) . In a pachinko gaming machine, an opening / closing device called a big prize opening is operated at the time of a big hit, and a game ball wins at the time of opening, thereby enabling a player to acquire a large amount of game balls.

  In this type of probability fluctuation type gaming machine, it is possible to immediately determine whether the winning symbol is a special symbol, and when the jackpot symbol is displayed, whether the probability variation is won or not, depending on the type of the specific symbol. If you know that the special symbol will win the variation, you can greatly enhance the interest of the player. However, when it turned out that it was a special symbol that was not selected for the probability fluctuation, the player's interest decreased at a stretch, and it was not possible to continue and enjoy the game of jackpot. The jackpot symbol here is determined in advance such that, for example, an odd symbol is displayed, the probability variation is won, and the even symbol is not selected for the probability variation.

  Therefore, recently, a probability variation type gaming machine called a post lottery type that displays as a production as if the lottery of probability variation is being performed during a jackpot game has also become known. This is because the probability variation winning / non-winning decision has already been determined inside the gaming machine when the special symbol jackpot is displayed, but on the liquid crystal display etc., the content that the probability variation lottery will be performed from now on This is intended to maintain the interest of the player during the jackpot game by directing the game (for example, a character performs a race) as a production.

  In addition, in the prior art, in the jackpot game that is performed immediately after the jackpot symbol is displayed, the probability variation is changed depending on the total number of winning game balls that enter the opening / closing jackpot. There is a lottery (see Patent Document 1). According to such a prior art, the player displays the jackpot symbol, and during the jackpot game that starts immediately after the performance (for example, a character race or the like is performed and the winning / losing result is performed) If the player who wins wins wins the probability fluctuation lottery), and if the probability change wins, then in addition to the jackpot joy, then the probability change again It will be possible to enjoy the joy of winning.

JP 2001-87485 A (5th page, FIG. 3)

  However, the post lottery method described above does not know whether or not the probability variation was won during the jackpot game, but in reality the lottery of the probability variation is performed in the internal lottery, Since it has already been determined whether or not the probability variation has been won at the time the symbol is displayed, the player's interest can only be sustained by the appearance. For this reason, depending on the player, it may be possible to determine whether or not the probability variation has been won based on the display of the jackpot symbol and the behavior during the jackpot game (display on the board surface of the pachinko machine or other display). Will not continue until the big hit game.

  Furthermore, in the prior art, the probability variation lottery is actually performed during the jackpot game, but the distribution is approximately 1/2 (if the total number of winning prizes is odd, the probability variation lottery is won, and even number In the case of, the lottery of the probability variation is determined to be not won), and when the probability variation is not won, that is, when it turns out that it is not won in the jackpot game, the player's interest will decline at a stretch End up. Also, the probability variation lottery probability is always fixed at a pre-determined probability of 1/2, which gives the player a sense of excitement without knowing how long the probability variation will continue, and unfortunately the probability Even if the change is not won, there is no expectation that the next chance of the random change will be given.

  Furthermore, in this method, depending on the player with high skill, it is possible to put the same number of game balls into the winning prize opening each time, so the act of hitting while stopping the launch of the game ball (so-called stop, pachinko game) By randomly pressing the release button on the handle for launching a game ball with a machine, etc., and adjusting the number of game balls to be launched) There is also a bad effect that you will be shot to win.

  Then, this invention makes it a subject to provide the technique which maintains the interest of the player accompanying grant of the lottery opportunity of a probability fluctuation | variation, and subsequent continuation.

(Solution 1)
The gaming machine of the present invention is activated and stopped in accordance with the player's operation in a state where a predetermined number of game values are multiplied for each game, and the display of the symbols is changed by the activation. , Provided with a symbol display device that displays a combination of a plurality of symbols at the time of the stop, based on the combination mode of the symbols displayed at the time of stopping the symbol display device, to give the player a prescribed number of game value as required In a gaming machine that can control the transition to a specific gaming state that is advantageous for the player when the combination of the symbols matches a predetermined specific display mode as well as ending one game, An internal lottery means for obtaining an internal lottery every time, a stop operation means capable of accepting a stop operation for stopping the symbol display device, and stop by the stop operation means When a work is accepted, when the winning result of the internal lottery is won, a stop control means that allows a combination mode of symbols corresponding to the winning type as a mode displayed when the symbol display device is stopped, and the internal Game state control means for performing control to shift the game state to the specific game state on condition that the combination mode of the displayed symbols matches the specific display mode when a specific winning type is obtained by lottery And a specific winning type high-probability lottery means for performing a predetermined specific winning type high-probability lottery separately from the internal lottery when the specific winning type is won in the internal lottery, and the specific winning type high-probability lottery If it wins a particular winning type high probability lottery by means the specific winning in the internal lottery the specific game state takes place in the game after the completion of A particular winning type probability changing control means for performing control to shift to a particular winning type high probability while relatively high change probability that s is obtained by the specific winning type high probability lottery means, the specific winning type high probability state Specific winning type high probability maintenance mode is selected from among multiple specific winning type high probability maintenance modes with different probabilities that can be won in the following specific winning type high probability lottery It is characterized by having a winning type high probability maintaining mode lottery means .

  The gaming machine of the present invention is a game in which the player decides the multiplication value of the gaming value every time, and when the player wins in the internal lottery of the gaming machine, the player performs a stop operation suitable for the winning type. The combination mode of symbols corresponding to the winning type is displayed. In particular, when a specific winning type is obtained in the internal lottery, the game state is controlled to the specific game state when the combination mode of the symbols matches the specific display mode. In this specific gaming state, the game is controlled to a so-called big bonus game (hereinafter referred to as a BB game) or a regular bonus game (RB game), during which the player has a large amount of gaming value (medals, coins, game balls, etc.). ). In addition, when BB (or an RB game may be included) is won by internal lottery, a lottery (specific winning type probability changing lottery) is performed to determine whether or not the winning probability of the next BB will be increased. When winning in the lottery, the internal probability of the BB (or RB may be included but will be explained below as a unified change to a high probability of winning BB) Is controlled with a high probability. Thus, when the specific winning type high probability state is reached, the player can reach the next BB (win) with a relatively small number of games in subsequent games. This is a very advantageous state in which a player can acquire a larger amount of game value than a BB or RB game, and it is possible to have a strong interest in a specific winning type probability change lottery. The timing for performing the specific winning type probability change lottery is as follows: when BB (or RB) is won by internal lottery, when BB (or RB) symbol is displayed as a combination, during BB (or RB) game play, BB (or RB) game end time or the like may be used. If none of the symbols displayed in the internal lottery of the gaming machine is won, it is avoided that a specific display mode (in this case, a combination of BB symbols) is displayed. Even if the stop operation is performed aiming at (BB symbol), the symbol combination is not displayed. In addition, when the winning of the specific winning type probability changing lottery is not won, the internal probability of the BB is not controlled with a high probability.

The gaming machine according to Solution 1 or 2, further comprising specific winning type probability change continuation lottery means for performing lottery to determine whether or not to continue.

  In the present invention, when a combination of BB (or RB) symbols is displayed in the specific winning type high probability state, whether or not to continue the specific winning type high probability state is determined. The lottery probability at this time is a continuation probability by the continuous lottery means described in the solving means 3. Since it is determined whether or not to continue the specific winning type high probability state based on this continuation probability, the player enjoys estimating which continuation probability is selected and the lottery is being performed. It becomes possible to play while remembering.

(Solution 4)
The solving means 4 is configured such that, when the specific winning type probability changing control means is not selected for the lottery by the specific winning type probability changing continuous lottery means, the probability performed in the internal lottery is returned to the original probability. A gaming machine according to any one of Solution 1 to 3 characterized by the above.

  In the present invention, when the continuous lottery in the specific winning type high probability state is not won, the internal probability of the gaming machine is returned to the original probability. In the specific winning type high probability state, BB (or RB) having a high internal probability is returned to the original probability. The player can confirm that the specific winning type high probability state has ended, and the goal is to display a combination of BB (or RB) symbols to receive the next specified winning type probability change lottery. You can play games.

(Solution 5)
The solution means 5 is that there are a plurality of combinations of symbols corresponding to the winning types, and the lottery by the specific winning type probability changing lottery means is performed when the display mode of the plurality of types of symbols is allowed. 5. A gaming machine according to any one of the solving means 1 to 4.

  In the present invention, it is possible to provide a plurality of types of specific symbols on which a specific winning type probability changing lottery is performed, not limited to a single type. As a result, the player constantly plays the game while paying attention to the combination display of the symbols, and it is possible to have fun in games other than the specific winning type high probability state. In addition, when a player tries to display a combination of the plurality of types of symbols (so-called “so-called”), he / she can enjoy the original fun of a gaming machine such as a slot machine by playing the game with full skill. It will also be a thing. In addition, the fact that the specific winning type probability change lottery does not know when it will start makes it possible to give the game a variety of variations. In addition, since the combination of the symbol is allowed, for example, if the lottery for changing the probability of a specific winning type is performed even in the case where it is not possible to display (so-called “missing”), a player with a low level of skill However, if the content is such that the specific winning type probability change lottery is performed only when it can be displayed, the player can also expect to enter the game with a strong willingness to increase the skill of the mainstay.

(Solution 6)
The solution 6 is characterized in that the specific winning type probability change control means returns the probability performed in the internal lottery to the original probability when the combination of the plurality of types of symbols is displayed. A gaming machine according to means 1 to 5.

  In the present invention, when the combination of the plurality of types of symbols is displayed, the specific winning type high probability state is terminated. It may be the same symbol as the symbol combination for which the specific winning type probability changing lottery is performed by the solving means 6, or may be different symbols. In any case, if the content is designed so that the combination of symbols is relatively difficult to display rather than the symbol that displays the combination too often, the player will end when they win the specified winning type probability change lottery. The player is enthusiastic about the game without taking a breath until the conditions are satisfied, and the skill of the first press is fully exhibited, and the fun and depth of the game machine's original way of playing (the press etc.) can be tasted.

(Solution 7)
The solution means 7 is such that the specific winning type probability change control means restores the probability to be played in the internal lottery to the original probability based on the fact that the game in the specific winning type high probability state has been performed a predetermined number of times. A gaming machine according to any one of the solving means 1 to 6, characterized in that.

  In the present invention, when a transition is made to the specific winning type high probability state, the specific winning type high probability state is terminated by a predetermined number of games in the specific winning type high probability state. The player manages to concentrate on one game at a time in order to display a combination of specific symbols (for example, BB symbols) with a high probability in some limited number of times. You will be able to enjoy the fun of the game in the high probability state of the specific winning type.

(Solution 8)
The solving means 8 further comprises an effect display means for enabling a gaming state performed based on a result of the specific display mode of the symbol to be displayed outside the gaming machine. This is a game machine described in the above.

  In the present invention, it is possible to perform an effect display on the player or the surrounding area using a display device such as a liquid crystal or a 7-segment LED toward the outside of the gaming machine. Thereby, it becomes possible for the player to estimate from the displayed contents of the effect, whether or not the specific winning type probability changing lottery has been won or how much the probability of the continuous lottery has been selected. Since it is possible to play a game while watching both the display of the combination of symbols and the display of the contents of the production, the player can make a number of effects in the game in the BB (or RB) game or in the game in the specific winning type high probability state. By playing with the contents and symbols as a clue, the fun of gaming machines such as slot machines doubles.

(Solution 9)
The solving means 9 is a multiplier determining means for determining a multiplier in a state where a predetermined number of game values are multiplied for each game, and a starting operation means for accepting a player's starting operation with the multiplier determined. And a symbol display device that rotates a plurality of rotating bodies with symbols in the circumferential direction to change the display of the symbols, while stopping the rotation of the rotating body and displaying a combination of the symbols. A stop operation means for receiving a stop operation by a player to stop the rotating body, and when the start operation is received by the start operation means, the rotation of the rotating body is started. During the rotation, the stop operation means When the stop operation is received, the rotating body driving means for stopping the rotating bodies in the order of reception and when all the rotating bodies are stopped by the rotating body driving means for one game, Based on the combination of the symbols at the time, a game value giving means for giving a specified number of game values to the player as needed, an internal lottery means for performing an internal lottery for each game and obtaining the winning result, Based on the stop operation means, only when a stop operation corresponding to the winning type won in the internal lottery is accepted, when all the rotating bodies are stopped by the rotating body driving means, the winning type Stop control means that can display a combination mode of symbols, and when a specific winning type is obtained in the internal lottery, the specific gaming state on condition that the combination mode of the symbols matches the specific display mode Triggered by a gaming state control means for controlling the transition of the gaming state to a specific winning type in the internal lottery, a predetermined specific winning type separately from the internal lottery A specific winning type probability changing lottery means for performing a probability changing lottery, and the internal lottery performed in the game after the specific gaming state is ended when the specific winning type probability changing lottery means by the specific winning type probability changing lottery means is won And a specific winning type probability change control means for performing control to shift to a specific winning type high probability state in which the probability of obtaining the specific winning type is changed relatively high. A gaming machine according to any one of the above.

  In the present invention, particularly in a gaming machine such as a slot machine, the player performs a starting operation in a state in which a multiplier of a game value (medal, coin, etc.) for playing a game is determined, and then the player performs Based on the stop operation, the combination of the corresponding symbols can be displayed only when the stop operation that enables the display of the combination of symbols selected in the internal lottery at that time is performed. Value is paid out and one game is completed. If a stop operation is performed in which a combination of symbols won by the internal lottery cannot be displayed, the symbol combination cannot be displayed even if the internal lottery is won. For example, even if BB is won in the internal lottery, the combination of BB symbols is not displayed unless a stop operation that can display the combination of BB symbols is performed. Here, when a stop operation capable of displaying a combination of BB symbols is performed, the combination of symbols is displayed, and a game called a BB game is started thereafter.

  In the present invention, first, when winning a specific winning type (for example, BB, hereafter unified by BB) by internal lottery, whether or not to increase the winning probability by BB internal lottery in subsequent games The lottery is performed. If the lottery is won, the winning probability of the BB is changed to a high probability after the BB game ends. Furthermore, when the state is changed to a state with a high probability once and BB is won in a game in a high probability state, a lottery is performed as to whether or not to continue the high probability state again. As a result, the player first wins the BB and advances the game with the joy of being able to display the combination of symbols and then expecting that the probability of the BB will be changed to a high probability. be able to. Further, when the BB has a high probability, it becomes a variety of games that cannot be anticipated and the player can proceed with the game while maintaining the interest.

(Solution 10)
The solving means 10 includes a random number generating means for generating a random number within a predetermined numerical range, and one random number among all random numbers generated within the numerical range for each game. Random number acquisition means for acquiring and a range of predetermined hit random numbers determined within the numerical value range are further divided into a plurality of winning ranges, and the random numbers included in each of the divided winning ranges are one of a plurality of winning types. A winning random number range defining means that associates and defines the random number acquired by the random number acquiring means with the winning range, and determines the winning type associated with the winning range to which the random number belongs in the internal lottery The resulting random number comparison determination means, and random number winning range changing means capable of changing the winning range when winning the specific winning type probability changing lottery A gaming machine according to any of the solutions 1 through 9, characterized.

  In the present invention, in the lottery performed by the internal lottery, all random numbers generated within a predetermined range are used as a denominator, and the range of random numbers within that range is determined as a numerator. This numerator may be in the same range as the denominator or may be in a range smaller than the denominator (as long as it does not exceed the denominator). Dividing the winning range of multiple winning types within this winning random number range, the result of the internal lottery depends on whether the acquired random number corresponds to one of the predetermined winning ranges of multiple winning types can get. The plurality of winning types include a small role symbol, a bonus symbol, and a lost symbol, and the obtained random number corresponds to one of these. In that sense, in the case of a losing design, it means that it has been won.

  In addition, when a specific winning type probability changing lottery is won, the winning range of subsequent random numbers can be changed. As a result, if the winning range of a specific winning type (for example, BB) is expanded, the probability of winning BB in the subsequent game is increased accordingly. Further, in this case, since all the winning ranges themselves are determined within a predetermined range, the winning range of the other winning types is reduced by the extent that the winning range of BB is expanded. The reduced winning type has a lower probability of winning in subsequent games. In the present invention, the winning range is not limited to one expansion and reduction, and a plurality of changes can be made. For example, in the case where the winning range of other small roles is expanded in addition to BB and RB, if the winning range of the lost game is reduced by that amount, the game development that the winning game will not be won much in subsequent games, In addition, if the winning range of BB and a specific small role is expanded and the winning range of RB and other specific small roles is reduced, a variety of game development variations in the subsequent games will be possible. Can enhance the interest of

  According to the present invention, it is possible to maintain the interest in changing the probability of the winning type for the player.

  Hereinafter, an embodiment in which the present invention is applied to a rotary gaming machine will be described in detail with reference to the drawings.

(Outline of one embodiment)
FIG. 1 shows a slot machine 1 that is a rotary gaming machine according to an embodiment. The slot machine 1 in FIG. 1 is of a type that uses, for example, medals, coins or the like as game media. In addition, there is a type using a game ball (so-called “parrot machine”) as a spinning-type game machine, and this type is also suitable as an embodiment. Further, in implementing the present invention, no substantial difference is caused regardless of which type is applied.

  FIG. 1 is a front view of a slot machine 1 including a box-shaped main body portion 2 and a front door 4 each having a rotating device and the like which will be described later. A plurality of slot machines 1 are installed side by side in a row in a state where a front view is shown as in FIG. A lending machine for medals and the like is installed between the gaming machine and the gaming machine, and the player can borrow medals and the like by inserting cash, a prepaid card or the like into the tying sand.

  The slot machine 1 has a front door 4 on the front surface facing the player. The front door 4 has two upper and lower hinges (not shown) in the left end of FIG. It can be opened and closed to the front in a single-open format. The front door 4 has a liquid crystal display 42 and a flat transparent plate (game panel) 6 in the upper half, and the arrangement thereof is a liquid crystal display 42 in the upper part obtained by further dividing the upper half of the front door 4 into two equal parts. A game panel 6 is provided at the bottom. The lower half of the front door 4 has a start lever, a stop button, a decorative plate and lamp 48, a tray 38, and the like. The arrangement is such that the lower half of the front door 4 is further divided into four equal parts, and when called 1/4, 2/4, 3/4, 4/4 from the top, the start lever is set to 1/4. There is a stop button, and 2/4 and 3/4 parts are decorative plates. This decorative plate is a transparent plate, and nothing is drawn in FIG. 1, but a logo or illustration of the title of the gaming machine is drawn. The 4/4 portion is a tray 38. A rectangular display window 8 is formed in the center of the game panel 6. The slot machine 1 according to the present embodiment includes three cylinders that rotate as an example of a mechanical variable symbol display device (rotating device) (each cylinder has a center portion as an axis. In a slot machine, this cylinder is called a reel, which will be unified as a reel), that is, in the front view of FIG. 10a is called a left reel, 10b is called a middle reel, and 10c is called a right reel, respectively. These reels 10a, 10b, 10c are installed in a box-shaped main body portion 2, and a front door 4 is attached. It is protected so that it cannot be touched directly by closing.

  Each reel 10a, 10b, 10c has a reel band on its outer periphery, and various symbols (for example, 21 pieces) are attached to its surface. FIG. 1 shows only some of the symbols, but the symbols are designed with numbers, letters, bells, watermelons, plums, apples, cherries, etc., or characterize the model of the slot machine 1. Includes characters, figures, symbols, and other designs.

  The slot machine 1 can change or stop the display mode of the symbols by rotating or stopping the reels 10a, 10b, and 10c. From the front surface of the slot machine 1, only a part of the reels 10a, 10b, and 10c is visible through the display window 8, and three symbols in the vertical direction for each reel 10a, 10b, and 10c when stopped. Is effectively displayed.

  In the game panel 6, display areas 12 and 14 are formed on both sides of the display window 8, and various character information and symbol information are attached to the display areas 12 and 14. A lamp unit (not shown) is disposed behind the transparent plate 6, and information in the display areas 12 and 14 is lit and displayed by transmitting light from the lamp. For example, when a player inserts a medal through the medal insertion slot 15 for the first time, the bet number of medals, that is, the bet number is added according to the inserted number, and the display area 12 on the left side corresponds to the bet number accordingly. An active line lamp (for example, 1 bet, 2 bets, 3 bets) is lit. At this time, if the medal acceptance operation in the slot machine 1 is a credit mode, which will be described later, medals placed in excess of the maximum bet number (for example, 3 bets) are stored as credits, and the credit number is numerically displayed on the display unit 16. Is done.

  Up to 50 credits can be stored, for example. As a result, the number of bets for the next game can be selected from the number stored in the credit by operating the bet buttons 18, 20, and 22 without inserting only the number of medals to be betted for each game. The game can proceed smoothly. At that time, the credits are subtracted from the number of stored bets. The bet buttons 18, 20, and 22 correspond to single bets (1 bet), 2 bets (2 bets), and MAX bets (3 bets), respectively.

  Note that when one bet is made, only one line (one broken line 11a in FIG. 1) of the middle symbols of the three symbols of each reel that can be visually recognized from the display window 8 is valid. . In the case of two bets, the total of the above-mentioned one line plus two lines (one broken line of 11b in FIG. 1), one line of the upper symbols of each reel and one line of the lower symbols side by side. Three lines are valid. When three bets are placed, the three lines include the upper symbol of the reel 10a, the middle symbol of 10b, the lower symbol of 10c in the front view of FIG. 1, and the lower line of the reel 10a. A total of 5 lines including 2 lines of 1 line rising to the right in the front view of FIG. 1 of the middle symbol of the symbol, 10b, and the upper symbol of 10c (two broken lines 11c in FIG. 1) are effective lines. Say something.

  In any case, when the player decides the number of bets for each game and operates the start lever 24 in a state where the effective line lamp is lit and displayed, the reels 10a, 10b, and 10c rotate, and the symbols change. Is called. Then, when the player operates the stop buttons 26, 28, and 30 while the reels 10a, 10b, and 10c are rotating, the corresponding reels 10a, 10b, and 10c stop rotating, thereby stopping the variation of the symbols. Is done. At this time, the presence or absence of a winning is determined from the combination of symbols on the active line, and if there is a winning, a bonus privilege is given according to the type of winning symbol (for example, bonus symbol, small role symbol, replay symbol, etc.) One game is over. The case where there is a win here is a case where the winning symbol (for example, bell) makes a stop (symbol display mode) where three winning reels, left, middle, and right, stop alongside the active line. Say. However, some specific winning symbols (for example, cherries) have been awarded even when they are stopped only on the effective line on the left reel or only on the effective line on the left / middle reel. Some will do.

  Note that if there is a prize accompanying paying out medals (for example, small prize winning, bonus winning), the number of payouts is displayed on the display unit 32. In the credit mode, the paid out medals are displayed on the display unit 16. Added to credit and stored. Of the medals paid out at this time, medals exceeding the maximum number of credits are paid out to the tray 38 through the payout opening 36. Alternatively, if there is a winning with a replay symbol, the immediately preceding active line is re-enabled and replay (replay) is possible as it is. Further, the player can cancel the credit mode by operating the settlement button 40 once to settle the medal storage (credit). Furthermore, if the settlement button is operated once again, the credit mode can be set again.

  The slot machine 1 according to the present embodiment has a liquid crystal display 42 above the display window 8, and the liquid crystal display 42 is used to provide images for effects and various bonus games as the game progresses. The number of medals is displayed. In addition, two speakers 44 are provided on the left and right of the payout opening 36, and sound effects, BGM, sounds, and the like accompanying the progress of the game are output from these speakers 44. In addition, lamps 45, 46, and 48 are disposed on the front door 4 at the center of the upper portion of the liquid crystal display 42 and its left and right ends, the lower left end of the start lever 24, and the lower right end of the medal slot 15, respectively. These lamps 45, 46, and 48 can perform effects by light-emitting decoration according to the gaming state.

(Internal configuration of slot machine)
FIG. 2 schematically shows configurations of various mechanism elements, electronic devices, operation members, and the like that are installed in the slot machine 1. The slot machine 1 has a main control board 50 for comprehensively controlling the progress of the game. The main control board 50 includes a CPU, a ROM, a RAM, an interface, etc. (all not shown). Has been implemented.

  The bet buttons 18, 20, 22 and the start lever 24, the stop buttons 26, 28, 30 and the settlement button 40 are all connected to the main control board 50, and these operation buttons use sensors (not shown). The operation by the player can be detected and the operation signal can be output to the main control board 50.

  The slot machine 1 accommodates other devices together with the main control board 50, and various signals are input from these devices to the main control board 50. In addition to the reel device 10 having the three reels 10a to 10c, the devices include a medal selector 52 and a hopper device 54.

  The reel device 10 has a position sensor (not shown) for detecting a reference position related to the rotation of each reel 10a, 10b, 10c, and a detection signal (index signal) from these position sensors is a main control board. 50 is input. The medal selector 52 detects medals inserted from the medal insertion slot 15 one by one and outputs a detection signal (inserted medal signal) to the main control board 50. The hopper device 54 has a payout sensor (not shown) that detects paid-out medals one by one, and a payout medal signal for each medal is input to the main control board 50 from the payout sensor. ing.

  On the other hand, a control signal is output from the main control board 50 to the reel device 10 and the hopper device 54. That is, the reel device 10 has a built-in stepping motor (not shown) for rotating the reels 10a, 10b, and 10c, and a drive pulse signal for controlling start and stop of these stepping motors is a main control. Output from the substrate 50. The hopper device 54 receives a driving signal from the main control board 50 in accordance with the type of the winning symbol, and the hopper device 54 receives the medal in response to this.

  The slot machine 1 includes a sub control board 56 in addition to the main control board 50. The sub control board 56 includes a CPU, a ROM, a RAM, an interface, a VDP, a sound source IC, an audio amplifier, etc. (all of which are shown in the figure). Not implemented). The sub control board 56 receives various command signals from the main control board 50, controls the operation of the liquid crystal display 42, the display units 16, 32, 34, and the speaker 44, and lights or blinks the lamps 45, 46, 48. I have control. Further, a detection signal from a mass sensor 70 installed at the lower part of the tray 38 is input to the sub-control board 56.

  Further, an external terminal board 58 is connected to the main control board 50, and the slot machine 1 is connected to the hall computer 60 in the game hall via the external terminal board 58. The external terminal board 58 plays a role of relaying various signals (inserted medal signal, payout medal signal, game status, etc.) transmitted from the main control board 50 to the hall computer 60.

  In addition, a power supply unit 62 is accommodated in the slot machine 1, and the power supply unit 62 takes in electric power from an external power source and generates electric power necessary for the operation of the slot machine 1. The electric power generated here is supplied from the power supply unit 62 to each unit.

  The power supply unit 62 is provided with a setting key switch 64, a reset switch 66, a power switch 68, and the like. None of these switches are exposed to the outside of the slot machine 1 and can be operated only by opening the front door 4 thereof. Among them, the power switch 68 is for turning on / off the power supply to the slot machine 1, and the setting key switch 64 is for changing the settings (for example, settings 1 to 6) of the slot machine 1. . The reset switch 66 is used to cancel an error that has occurred in the slot machine 1 and is also operated when changing the setting together with the setting key switch 64.

(Game processing)
Next, the flow of game processing in the slot machine 1 will be described. The following game processing proceeds in accordance with a processing procedure on a control program executed by the CPU of the main control board 50.

(1. Crotch game processing)
FIG. 3 shows one processing procedure for one basic game (rotating game) in the slot machine 1. One game starts from start processing (step S10). This starting process is a process for starting the rotation of the reels 10a, 10b, 10c. Here, a random number triggered by the insertion of a medal or the operation of the bet buttons 18, 20, 22 or the operation of the start lever 24 is used. A process such as lottery is performed. The details of the starting process (step S10) will be described later in detail using another flowchart.

  In one game, a stop process (step S20) is executed following the start process (step S10). This stop process stops the rotation of the reels 10a to 10c and controls the stop position. This corresponds to a process called “reel control”. For stop processing using reel control, there are two methods, for example, a table method for determining the final stop position with reference to two of the winning combination and the position where the stop button is pressed, and a control method for drawing the winning combination to the maximum In this case, either may be used. The winning combination will be described in the starting process described later. Stop processing using reel control will also be described later using another flowchart.

  When the stop process is finished by the reel control, the determination process (step S30) is executed next. This determination process determines whether or not a combination of symbols is displayed on the effective line from the display mode (outgoing) of the symbols displayed when all the reels 10a, 10b, and 10c are stopped. It is for providing the game result according to. The main benefit of the game results is the medal payout, but even if there is no medal payout, the bonus game is given according to the type of displayed combination symbol (big bonus symbol, regular bonus symbol, etc.) In some cases, the internal state (various modes) may be changed separately from the medal payout. The specific contents of the determination process will be described after the stop process.

(2. Start processing)
FIG. 4 specifically shows the contents of the start process. Here, first, the insertion of medals or the operation of the bet buttons 18, 20, and 22 is awaited (step S101). As long as the player does not make a bet or insert a medal (No), the start lever 24 is not activated, so the determination in Step S104 is denied (No) and the standby state (Step S101) continues to be looped. However, if replay symbols to be described later are prepared in the previous game, the determination in step S104 is affirmed (Yes), and the process proceeds to step S105.

  When there is a bet operation or a medal insertion, an acceptance process (step S102) is performed in response to this, and the effective line lamp is turned on according to the number of bets. In the acceptance process (step S102), a medal insertion command or a bet command is transmitted from the main control board 50 to the sub-control board 56.

  Subsequent to the acceptance process (step S102), a start lever valid process (step S103) is performed, and the operation of the start lever 24 is substantially validated for the first time. When the player operates the start lever 24 in this state, the determination in step S104 is affirmed (Yes), and then the start lever invalidation process (step S105) is performed.

  When the start lever 24 is operated, random number extraction (random lottery) is performed using this as an opportunity (step S106). Further, the timing for extracting the random number after receiving the operation of the start lever 24 is not particularly defined, and an appropriate extraction timing can be set in the programming process.

In the next flag processing (step S107), winning / losing is determined from the extracted random value, and in the case of winning, a flag corresponding to the type of winning combination (small role, special small role, etc.) is turned ON. The winning flag command is transmitted from the main control board 50 to the sub control board 48.
In the case of a loss, a lost flag that cannot be used for any winning combination (small combination, special small combination, etc.) is turned ON. A winning / losing flag (a so-called establishment flag) is obtained only when the corresponding symbol is aligned when the corresponding flag is established. Each prize bonus will be described later using a separate flowchart in the determination process.

  When the above flag processing (step S107) is performed, it is determined whether or not the wait timer started in the previous start processing has timed up (for example, 4.1 seconds have elapsed) (step S108). When time-up (Yes) is confirmed, each reel 10a, 10b, 10c is started (step S109), and a wait timer from this point to the next start is started (step S110).

(3. Reel stop processing)
FIG. 5 shows the contents of reel stop processing by the table method as an example. Since a well-known technique can be applied to the reel control, the flow of processing will be schematically described here.

  In the reel stop process, first, the reel control table is selected according to the establishment flag indicating the winning result at that time (step S201). A reel control table having a plurality of patterns for all the winning results is prepared in advance, and these are stored in the ROM of the main control board 50 as read-only table data.

  With the reel control table having an appropriate pattern selected, the system waits until the stop button 26, 28, 30 is pressed (steps S202, S210, S217, S219). In these standby states, it is determined whether each of the left and middle reels 10a, 10b has already stopped, or whether the first reel stop flag is not set (= 0). At the same time, it is determined whether any one of the left, middle and right stop buttons 26, 28 and 30 is pressed. If none of the stop buttons 26, 28, and 30 are pressed, the determinations in steps S219 and S209 are both denied (No), and steps S202 and after are repeated.

  For example, if the left stop button 26 is first pressed in accordance with a so-called “forward push” or “forward scissor push” procedure (step S202 = Yes), the first reel stop flag is not set at this time ( Therefore, the first reel stop process (step S204) is executed for the left reel 10a. Here, the “first reel stop process” means a process for stopping the reel first.

  Alternatively, when the center stop button 28 is first pressed in accordance with the so-called “middle push” procedure (step S210 = Yes, step S211 = Yes), the first reel stop process (step S212) is executed for the middle reel 10b. The In addition to this, when the right stop button 30 is first pressed in accordance with the so-called “reverse push” or “reverse scissor push” procedure (step S217 = Yes, step S218 = Yes), the right reel 10c A one reel stop process (step S219) is executed.

  When the first reel stop process (steps S204, S212, and S219) is performed for any one of the left, middle, and right reels 10a, 10b, and 10c, a plurality of reel control tables corresponding to the formation flag at that time are stored. Thus, one table pattern is selected based on the random value. For example, for one winning combination “Bell”, a plurality of reel control tables are prepared in advance to stop the symbol “Bell” on the reels 10a to 10c on the active line. It means that one pattern is selected. When one pattern is selected, the stop positions of the reels 10a to 10c are controlled based on the reel control table. Thereby, for example, the symbol “bell” is stopped somewhere on the active line.

  For example, taking a pattern in which the left reel 10a is stopped first along the forward pressing procedure, the first reel stop process is performed on the left reel 10a in step S204. At this time, the main control board 50 transmits a stop information command (first stop information command) indicating the stop eye of the left reel 10 a to the sub control board 56.

  In the next step S206, reel control tables (stop tables) for the remaining middle and right reels 10b and 10c are determined by random lottery. Specifically, assuming that the symbol “bell” is stopped at the lower position when the left reel 10a is stopped in FIG. 1, the winning line is selected from the lower line or the right-up line at that time (in the case of MAX bet). In this case, either one (for example, a line rising to the right) is selected by random number lottery. The random number lottery distribution rate may be about half.

  When the above processing (step S206) is performed, the first reel stop flag is turned ON (= 1) (step S207), and the left reel stop flag is turned ON (= 1) (step S208). ). Since all the reels 10a to 10c are not stopped at this stage, the determination in step S209 is negative (No), and step S202 and subsequent steps are executed.

  Then, since the left reel 10a has already stopped at this time (step S202 = No), when the stop button 28 at the center position is pressed secondly (step S210 = Yes) along the forward pressing procedure, the first reel After the stop flag is determined (step S211 = No), the middle reel stop process (step S213) is executed. In the middle reel stop process, the stop position is controlled based on the reel control table (stop table) previously selected for the middle reel 10b. As a result, in the example of the above-mentioned right-up winning line, the symbol “bell” on the middle reel 10b is stopped at the middle position. In addition, the top of the stop is a state in which two symbols “bells” are aligned on the left and middle reels 10a and 10b on the right-up line (so-called “right-up template”). At this time, the main control board 50 transmits a stop information command (second stop information command) indicating the stop eye of the middle reel 10 b to the sub control board 56. In this case, since the middle reel 10b is in the second stop, steps S212, S214, and S215 are all bypassed, and the middle reel stop flag is only turned ON (= 1) in step S216.

  Similarly, when the right stop button 30 is finally pressed (step S217 = Yes), the reel control previously selected for the right reel 10c is passed through the determination of the first reel stop flag (step S218 = No). The stop position is controlled based on the table (stop table) (step S220). As a result, the symbol “bell” on the third right reel 10c stops at the upper position, and the outcome when all reels are stopped is the state in which three symbols “bell” are lined up on the line going up to the right. Become. At this time, the main control board 50 transmits a stop information command (third stop information command) indicating the stop eye of the right reel 10 c to the sub control board 56. In this case, since the right reel 10c is in the third stop, steps S219, S221, and S222 are all bypassed, and the right reel stop flag is turned ON (= 1) in step S223.

  If the all-reel stop flag is turned on through the processing so far, the determination in step S209 is affirmed (Yes), and the processing by the main control board 50 exits this routine.

  The above is an example of the reel stop process by the table method. In addition to this, there is a reel stop process by a control method, but since a known process can be applied to this, a specific description is omitted here. In this embodiment, either the control method or the table method of reel stop processing may be executed, and which method should be adopted may be determined as appropriate when constructing the control program.

(4. Judgment processing)
FIG. 6 specifically shows the contents of the determination process. When all the reels 10a, 10b, and 10c are stopped by the reel stop process described above, the main control board 50 performs a process of confirming the output displayed at that time (step S301).

  Next, whether the symbol displayed as a combination from the outcome when all reels are stopped is a big bonus symbol (step S302), a regular bonus symbol (step S303), or a small role symbol (step S304). Whether it is a replay symbol (step S305) or a lost symbol is determined. Then, if it is determined that the symbol displayed as a combination corresponds to either the big bonus (BB) or the regular bonus (RB) (Yes), a sound effect that informs that the symbol combination is displayed. A command is transmitted to the sub control board (steps S306 and S307). When it is determined that the symbol of the displayed combination corresponds to a small role (step S304 = Yes), the hopper device 54 is instructed to perform a medal payout operation corresponding to each small role symbol, and a payout sound command. Is transmitted to the sub-control board 56 (step S308). Alternatively, when it is determined that a combination of replay symbols has been displayed (step S305 = Yes), a replay process (step S311) is executed. Here, the replay process means that the next game can be executed as a replay without newly inserting medals or performing a betting operation. In that case, the number of active lines is the same as the active line of the game with the replay symbols (for example, when replays are completed as a result of starting the game with 3 bets, when replaying is started at the next game. The number of lines for 3 bets is also valid).

  When it is permitted to display the big bonus symbol or the combination of the regular bonus symbol, that is, in the flag processing of FIG. 4, the winning flag of the big bonus (BB) or the regular bonus (RB) is turned ON, and the established flag symbol is If they are ready, in the case of a big bonus depending on the combination displayed at that time, a specific winning type probability change process in step S309 (a) is followed by a BB game process (step S309 (b)) or a regular bonus. / JAC game game process (step S310) is executed, and the determination process ends. Details of the specific winning type probability changing process will be described later.

  If it is allowed to display a combination of a small role symbol and a replay symbol, a payout or replay process is executed according to the combination symbol displayed at that time, and the winning flag for the small role or replay is turned OFF. (Steps S312 and S313) This process ends. In addition, when the loss flag is ON or the symbols corresponding to the establishment flag are not aligned on the active line (other than when the loss flag is ON, the fact that it will be missed is referred to as “missing” below) (step S305 = No), the establishment flag other than the BB or RB winning flag is turned off (step S314), and the determination process is also ended. Here, the establishment flags other than the BB or RB winning flag are turned OFF. That is, the winning flag of BB or RB is maintained. This is because BB or RB is more advantageous for the player than for a bonus when a small role or replay is displayed as a combination. The advantage of this BB or RB benefit will be described later. Furthermore, since BB or RB has a small number of symbols for each reel (for example, 1 to 3), even if the BB or RB winning flag is turned on, it is necessary to stop (so-called) to aim at the symbol. There is. That is, when the flag turned ON is other than the winning flag of BB or RB, the established flag disappears even if the symbols corresponding to the established flag are aligned or missed in the turned-on game. However, the winning flag of BB or RB is maintained until the symbols are aligned. The maintenance of the BB or RB winning flag can be said to be a convenience designed to prevent a significant difference in the benefits of the BB or RB due to the difference in the skill of the player.

  When the process proceeds to the big bonus game process (step S309 (b)) or the regular bonus / JAC game game process (step S310), the BB or RB winning flag is turned OFF during each process.

  The slot machine 1 of the present embodiment is a gaming machine that performs a lottery to increase the probability of a specific winning type (to increase the probability), and the specific winning type probability changing process is executed in the determination process. If you move to a specific winning type high probability state, the probability of winning with a specific symbol (big bonus symbol, regular bonus symbol) will be significantly high, and it will be possible to reach with a small number of games until winning the next specific symbol . When winning the specific winning type probability changing lottery, the continuation rate is also determined. Based on the determined continuation rate, if the transition to the specific winning type high probability state is made, the specific winning type high probability state will be continued based on the continuation rate determined in the specific winning type probability change process at the next winning of the specific symbol. Whether or not a lottery is performed, and a specific winning type probability change continuous lottery is performed.

(Special game state)
In the slot machine 1 of the present embodiment, if there is a winning with a big bonus symbol (for example, “7-7-7”) or a regular bonus symbol (for example, “BAR-BAR-BAR”), The game proceeds to a special game state called “Bonus Game” or “Regular Bonus Game”. These big bonus games and regular bonus games include multiple game opportunities, and there is a possibility of paying out medals etc. in the meantime, so it is advantageous for the player than usual I can say that.

  Further, in the big bonus game and the regular bonus game, the former includes more game opportunities, and in the slot machine 1 of the present embodiment, during one big bonus game (for example, twice). The opportunity to play JAC games (regular bonus games) is included. Both the big bonus and the regular bonus are in the form of a winning combination, but may be in the form of only BB or only RB.

(1. RB / JAC game processing)
FIG. 7 specifically shows the contents of the RB / JAC game game process. Here, first, as an initialization process, the RB winning flag is turned OFF, and the random value lottery winning value table is changed for the RB / JAC game (step S401). The hit value table changed here has more hit values for JAC symbols than usual, and a combination of JAC symbols is displayed almost every time (for example, 1/1. 1).

  Next, a start process (step S402) and a stop process (step S403) of the reel device 10 are executed. When all reels 10a, 10b, and 10c are stopped by the stop process, the outcome at that time is transmitted from the main control board 50 to the sub-control board 56 (step S404), and the RB / JAC game counter is incremented by one. (Step S405).

  Next, it is determined whether or not the outcome when all the reels 10a, 10b, and 10c are stopped is a specified symbol combination (step S406). The symbols specified here are usually the same as the JAC symbols (dedicated “JAC-JAC-JAC” or dual-purpose “Replay-Replay-Replay”). A mode in which a combination is displayed (for example, “BAR-replay-replay”, “7-replay-replay”, etc.) may be provided. If the outcome at the time of the stop is not a combination of JAC symbols (step S406 = No), the process proceeds to step S410 and the establishment flag is turned OFF. In this case, either the lost flag was turned on in the lottery, or the reels could not be stopped so that the player could display the symbols as a combination even if the winning flag was turned on. Conceivable. Conversely, if it is determined that the outcome at the time of stoppage is a winning symbol (Yes), the main control board 50 drives the hopper device 54 to execute a prescribed number (for example, 15) of medal payout and payout The sound command is transmitted to the sub control board 56 (step S408). When a payout is made, the payout counter is counted up by that number (step S409), and subsequently, the establishment flag is turned off (step S410).

  In step S411, it is determined whether or not to end the JAC game (regular bonus game). While the number of times the combination of JAC symbols has been displayed during the JAC game (regular bonus game) has not reached a certain number (for example, 8 times), the end determination is negative (No), and the process returns to step S402 to return to the JAC game ( Regular bonus game) continues. Thereafter, when the number of times the combination of JAC symbols is displayed in the JAC game (regular bonus game) reaches a certain number (for example, 8 times), it is determined that the JAC game (regular bonus game) should be terminated (Yes). Is done. In this case, the process proceeds to step S512, JAC game (regular bonus game) end processing is performed, and the winning value table is returned to the state before the change.

(2. Big bonus game processing)
FIG. 8 specifically shows the contents of the big bonus game process. Here, first, initialization processing is performed, and the random value lottery winning value table is changed for the bonus game (step S501). The hit value table changed here is composed only of the hit value of the JAC symbol.

  Next, the big bonus winning flag is turned off (step S502), and then the RB / JAC game processing is executed (step S503).

  When the RB / JAC game processing is finished once, the JAC game counter is counted up there (step S504).

  In step S505, a game called a bonus game (only once) is performed, a combination of JAC symbols is displayed, and a second RB / JAC game game process is started (step S506). The bonus game here is a game for starting the second RB / JAC game. In the present embodiment, in the RB / JAC game game, the game value (coins, medals) is set to 1 bet (that is, 1) and the game is advanced. It is good also as contents to perform in. By doing so, the player becomes completely unaware of the first (second) and second (or break) intervals between the RB / JAC games, so the game machines developed so far (the first RB / JAC) Players who have become accustomed to a different game after the game is over and then the second RB / JAC game is started) can be given a fresh game development, It is possible to remarkably enhance the interest.

  When the second RB / JAC game processing is completed, the JAC game counter is incremented there (step S507), and then the end processing and the winning value table are restored (step S508). In the present embodiment, for example, a maximum of 30 game opportunities are not provided during the BB. This is because the present invention makes it possible to develop a variety of appearance patterns (unexpected development) of games in a normal state and games in a specific winning type high probability state, thereby enabling an increase in the interest of the player That's why. For this purpose, a small number of small-games are eliminated, the number of acquired games is reduced, and there are provided many opportunities to shift to a specific winning type high probability state (that is, more chances to win more by BB). In other words, by making the BB winning probability high, if the chance of giving the specific winning type probability changing lottery increases, it is possible to attract the player's interest in the development of the game.

  In the slot machine 1 of the present embodiment, the first regular bonus game is started immediately after the BB symbol combination is displayed, and the JAC symbol combination is displayed again after the game ends, and the second regular bonus game is started. It has become a form. The hit value table for the actual bonus game is referred to only for one game between the first regular bonus and the second regular bonus. Therefore, from the viewpoint of the player, it is felt that the combination of JAC symbols is displayed continuously (for example, 17 times), and medals can be obtained in a short time with a good tempo. In addition, for players who are accustomed to the big bonus game of the conventional gaming machine, the game will have a fresh taste, and the interest in the big bonus game can be enhanced.

(Specific winning type high probability state)
As described above, the slot machine 1 of the present embodiment is a gaming machine that shifts to a gaming state of “specific winning type high probability state” (hereinafter referred to as a specific winning type high probability state). In the winning type high-probability game, the player can win the next jackpot without increasing the number of games and without reducing the number of medals. Therefore, it can be said that the fact that the specific winning type high probability state continues for the player is an advantageous gaming state over the normal game because the special game (that is, BB here) is in a state where it is easy to win continuously. . The normal game here is a game other than a special game and a game in a specific winning type high probability state described below.

  Compared to the case where the player has shifted to BB game but has not won the specific winning type change lottery, it is advantageous that the next BB will be reached with a small number of games and that medals will not be reduced so much. It can be said that there is. Next, “specific winning type probability change” for shifting to the specific winning type high probability state will be described below.

(1. Specific winning type probability change)
A gaming machine represented by this embodiment, such as a slot machine, a parrot machine, and a pachinko machine, has a lottery lottery with a certain probability (determined in advance from power-on) for each game. The game is advanced while being paid out based on the result. Since the jackpot lottery is performed with the same probability every time, the expectation of the same jackpot every time (for example, if there is a gaming machine that hits the jackpot with a probability of 1/200, the jackpot with 1/200 times each time (that is, BB in this example) It means that you can have expectations for). However, lottery with the same probability every time means that the game can be played with the same expected value whenever the game is started, but the game progress has various variations (for example, consecutive big hits (BB It is difficult to create a so-called “(big hit) wave” that makes it difficult to predict the undulations of this wave. Therefore, a specific winning type probability change is one in which the probability of jackpot is changed (varied) for a certain period when certain conditions are met, and the game progress has various variations. In this specific winning type probability change, it is possible to change not only the specific symbols (BB, RB) but also the probability including, for example, SB (single bonus), small role, and replay. Thereby, in a game in a specific winning type high probability state, a specific symbol (for example, BB) having a high probability compared to a normal game is in a state where it is easy to win. In this period, that is, in the specific winning type high probability state, it is possible for the player to play the game with almost no reduction in medals compared to the normal game. In addition, there is continuity in the specific winning type probability change, and the game in the specific winning type high probability state is continued a plurality of times, so that the player can make a specific symbol (for example, BB) multiple times within a short number of games. You can earn medals while repeatedly displaying the combination.

(2. Specific winning type probability change process)
The specific winning type probability changing process that can be said to be a main component of the present embodiment will be described using a flowchart. FIG. 9 specifically shows the contents of the specific winning type probability changing process. In the present embodiment, a specific winning type probability changing lottery is performed immediately after the combination of BB symbols is displayed. However, the timing of this lottery is determined at the same time when the BB is won by an internal lottery. The content may be a type probability change lottery or after the BB game is over.

  First, in step S601, it is determined whether or not a specific winning type high probability state is present. If it is determined that the winning type is not in a high probability state (No), the process proceeds to step S602, and a specific winning type probability changing lottery is performed. If the specific winning type probability changing lottery is not won (No), the processing is terminated. If the lottery here (1/5) is won (Yes), then in step S603, the continuation rate of the specific winning type probability change is determined. This continuation rate is as shown in the continuation distribution table of Table 1. Specifically, it is the winning probability in the continuous lottery performed when the combination of BB symbols is displayed next time. For example, if the 90% continuation rate in Table 1 is determined, the probability of winning the continuous lottery at the end of the next BB is 90%, and the probability of continuation is tripled compared to the 30% continuation rate in Table 1 Therefore, it can be said that there is a very high possibility that the number of continuations of the specific winning type probability change (the number of winning BB in the game in the specific winning type high probability state) will increase. That is, for the player, in addition to the expectation whether or not to shift to the specific winning type high probability state, it is possible to proceed with the game while having a great interest in this continuation rate.

  When the continuation rate is determined in step S603, the random value lottery value table is changed to the specific winning type high probability table (step S604), and the state is shifted to the specific winning type high probability state.

  If it is determined in step S601 that the specific winning type is in a high probability state (Yes), a continuous lottery is performed based on the continuation rate determined when the previous combination of BB symbols is displayed in step S605. If the lottery is lost (No), the random value lottery value table is restored (step S606). If the continuous lottery is won (Yes), the process ends without changing the winning value table and the continuation rate. That is, as long as the continuous lottery continues to be won, the specific winning type high probability state will continue.

  Table 2 shows a range of random value lottery values in normal games (non-specific winning type high probability game, non-BB game, non-RB game). On the other hand, Table 3 shows a range of winning values for random lottery at the time of gaming in a specific winning type high probability state.

  In Table 3, since the replay probability is 10 times that of the normal game together with the BB probability, in the game in the specific winning type high probability state, the replay will be arranged almost every time, and the player reduces medals. The game can be continued until the next BB symbol combination is displayed. In addition, if the probability of other small roles can be changed to a high probability in the specific winning type high probability state, it is possible to continue the game while increasing the medals until the next BB symbol combination is displayed. become.

(Random lottery value table)
The random value lottery value table will be described based on Table 2. First, considering a one-dimensional graph from 0 to 16383, 0 to 1339 is a bell, 1340 to 1439 is a watermelon, and 1440 to 3684. The range is determined to be replaying, cherry from 3865 to 3974, BB from 3975 to 4054, RB from 4055 to 4094, and losing from 4095 to 16383. The winning type is determined depending on which range the acquired value corresponds to (Table 4). As shown in Table 3, when the specific winning type has a high probability, the range of the winning value is changed. Regarding this change, the winning value may be changed in the range from 0 to 16383 (Table 5), or the winning value of the winning type to be changed to the range of the winning value of the losing will be provided (Table 6). Also good. Moreover, it is not limited to these.

  However, if multiple small roles are made highly probable in the specific winning type probability change lottery, the number of winnings will increase significantly and the profit balance between the hole and the player may be disrupted. If it is possible to keep the medal payout rate at a certain level, such as by reducing the probability of winning the bell, the balance between the profits of the hole and the player can be obtained. For example, if the payout rate of medals is set to 50% during normal games and maintained at 100% while a game in a specific winning type high probability state is being performed, the player can play games without reducing medals. Can proceed. Here, the medal payout rate is the ratio of the cumulative payout number of medals to the cumulative number of medals inserted. The payout rate is not limited to the above 50% or 100%.

(Direction processing)
The above is an example of game control by the main control board 50, but in the slot machine 1 of the present embodiment, the presentation operation is controlled by the sub-control board 56 as the game progresses.

  FIG. 10 shows an example of effect processing executed by the sub control board 56. When the slot machine 1 is turned on, an initialization process is first performed in the effect process (step S801). Next, a medal insertion command transmitted from the main control board 50 is awaited. When the medal insertion command is actually transmitted, an effect of outputting an insertion sound, a betting sound, etc. is performed in accordance with this command (step S802).

  Subsequently, a winning (start) flag command transmitted from the main control board 50 is awaited (step S803). The winning (starting) flag command is transmitted from the main control board 50 in response to the operation of the starting lever 24. When the winning (starting) flag command is received, the sub-control board 56 controls the rendering operation in accordance with the winning (starting) flag command. . The effect operation here is, for example, an output of a reel start sound or a notification effect of a winning combination by the liquid crystal display 42.

  When the start effect is performed, the first to third stop information commands are then awaited (steps S804 to S806). When the three stop buttons 26, 28, and 30 are operated in order, the first to second stop information commands are sequentially transmitted from the main control board 50 to the sub control board 56. Control of the presentation operation according to the winning flag and the first to third stop information commands is performed. The effect operation here is, for example, output of each reel stop sound, effect of turning off the reel, image effect by the liquid crystal display 42, and the like. In particular, when the third stop information command is received, an effect operation corresponding to the winning combination is performed (step S806).

  Then, since a payout command is transmitted from the main control board 50 according to the result of the determination processing, the sub control board 56 receives this and produces an effect by the payout sound output (step S807). Further, a game status command transmitted from the main control board 50 is awaited here, and the current game status is examined from the received command. The game status represents, for example, “Big Bonus Game”, “Regular Bonus Game”, “JAC Game”, or the like.

(Various effect processing including effect processing of specific winning type probability change lottery in BB game)
In this embodiment,
(1) Whether or not a lottery for changing a specific winning type probability was won.
(2) Which continuation rate was selected?
For these two items, an effect process that stirs up the player's expectation is performed.

  FIG. 11 is a flowchart specifically showing various effect processes. In step S901, it is determined whether a combination of BB symbols has been displayed. If it is determined that the combination of BB symbols is not displayed (No), a normal effect process is performed (step S905). If it is determined that the combination of BB symbols has been displayed (Yes), it is determined in step S902 whether or not it is in a specific winning type high probability state. When it is determined that the specific winning type is not in a high probability state (so-called first win) (No), a specific winning type probability changing lottery game effect process (step S904) is performed. When it is determined that the specific winning type is in a high probability state (Yes), a continuous game effect process (step S903) is performed. Moreover, it is good also as a content which adds sounding operation | movement by the sounding device which emits a sound toward the exterior of game machines, such as a speaker, to these various production processes. In this way, visual (liquid crystal display or the like) and auditory (speaker or the like) are produced, and the player's presence can be raised.

  The first win mentioned above is not a BB that is won from a specific winning type high probability state and a symbol combination is displayed, but is a BB that is won from a normal game and a symbol combination is displayed. For example, a BB in which a combination of symbols is displayed in a game in the specific winning type high probability state is not a first winning type, and the specific winning type high probability state is shifted to the specific winning type high probability state in the first winning BB. It is said that it is BB. Specifically, no matter how many times the BB symbol combination is displayed before the BB where the current symbol combination is displayed, the BB where the current symbol combination is displayed is the symbol from the normal game. When the combination is displayed, it is said that the initial hit is BB.

(1. Specific win type probability change lottery game production)
First, whether or not the probability variation is won is determined throughout the BB game as an effect of the probability variation lottery game. In the RB / JAC game for the first time during the BB game, it is assumed that the result is not known whether the particular winning type probability changing lottery has been won or not. 12 to 17 show examples of various effect images displayed on the liquid crystal display 42 during the specific winning type probability changing lottery game. As a specific example, when the first RB / JAC game is started, an effect of determining a racehorse to bet on is performed (FIG. 12). A race is started with a bonus game (FIG. 13), and a fierce race is developed in the second RB / JAC game (FIGS. 14 and 15), and the second RB / JAC game is completed upon completion of the race (FIG. 13). 16, 17). The result here is produced as a result of the specific winning type probability changing lottery. When FIG. 16 wins the specific winning type probability changing lottery, FIG. 17 is an effect image when the lottery is not won.

  During the BB game, the player does not know whether or not he has won the specific winning type probability change lottery until the game is over, so the game proceeds with a sense of expectation (sweat in his hand) until the end. Also, the winning expectation degree (displayed as a winning rate) is determined for the racehorse determined during the first RB / JAC game (the winning rate of each horse in FIG. The player is able to predict the race development (the second RB / JAC game) to some extent depending on which horse is decided. In the second RB / JAC game, the horse of your choice actually runs the race, but even if you choose a horse with a low win rate (the expectation of winning is low), a helping character (player) If a horse or other person appears when the betting horse is likely to lose, prepare an effect that reverses at the end of the goal (for example, Koutaro (middle character wins at the end in Fig. 15)) By giving an effect that reverses the player's expectation, it is possible to give a sense of expectation to the result of the specific winning type probability changing lottery until the end.

(2. Continuous game production)
After transitioning to this high-special selection type high-probability state, the high-special-choice type high-probability state will continue until the next BB is won. A continuous lottery is performed based on the rate. Since the player does not know which continuation rate is selected at the time of the first hit, the player is expected to continue whether or not to continue even during this continuous lottery (that is, during a BB game game in a specific winning type high probability state). Prepare a production. For example, FIG. 18 to FIG. 21 are examples of various effect images of a continuation game performed during a BB game game in a specific winning type high probability state. The race that has been upgraded again this time with the horse that was selected when winning the specific winning type probability change lottery for the first time (the horse that won the race at the time of the first hit, for example, a five-frame Koutaro) (Fig. 21) ) And race. There are several stages in this grade (Figs. 18 to 20), and it is possible to estimate which continuation rate is selected to some extent by the player depending on which race is entered and the strength of the competitors that appear. If it takes a form, it will come to observe carefully to the fine detail of production, and it can attract interest to estimating the continuation rate, whether it has won the continuation lottery, etc. If this estimation is limited to about 50% to 60%, the player can enjoy the prediction in the middle of the production, and can fully enjoy the fun of the game until the end of the production.

  The above is the specific winning type probability changing lottery and the continuous lottery processing and its effect processing in the present embodiment. In the present embodiment, the specific winning type high probability state continues until the next BB symbol combination is displayed. However, the present invention is not limited to this. For example, the specific winning type high probability state may be ended until a combination of symbols such as RB, SB, and a specific small combination (for example, cherry) is displayed. Moreover, it is good also as a form which is complete | finished after the game in a specific winning kind high probability state passes a predetermined number of times, or a specific small part etc. continues until the combination of the said symbol is displayed predetermined times.

  Also, the specific winning type probability change lottery is not limited to the case where a combination of BB symbols is displayed. For example, when a combination of symbols of RB, SB or a specific small role (for example, cherry) is displayed. It is good also as a form which performs lottery. Also, the condition for ending the specific winning type high probability state at that time is the same as the above, and the form or specific small role that ends after the game in the predetermined winning type high probability state is continued a predetermined number of times. A form that terminates when displayed is also possible. Hereinafter, an example (modified example) in which a part of the embodiment described above is changed will be described.

(Modification 1)
The specific winning type probability changing lottery in the present embodiment is not performed, and when a combination of BB symbols is displayed, it may be a content that always shifts to the specific winning type high probability state. The range of the random value lottery value is the same as in Table 2. However, as a condition for ending the specific winning type high probability state, the specific winning type high probability state is displayed when a combination of a specific small role (for example, cherry) is displayed in the game in the specific winning type high probability state. End. In addition, instead of the continuation rate described in the present embodiment, when the combination of cherry symbols is displayed, an end lottery is performed (the probability that a combination of winning symbols is displayed that returns from the specific winning type high probability state to the normal state). In order to return from the advantageous state to the normal state, a so-called falling may be provided (hereinafter, the falling or the lottery is unified as a falling lottery) (for example, a combination of cherry symbols is displayed) For example, it falls down by 1/2 due to the final lottery). However, although not shown in the figure like the cherry in this example, if the specific small combination is designed to have a small number of arrangements on each reel, the player may miss it due to the skill of the player. Therefore, even if the combination of cherry symbols can be displayed when the winning flag for cherry is turned on, or if it is missed, it will not be disadvantageous for a player with a high level of skill. It will be. In addition, it is possible to prevent losing a specific winning type high probability state by losing it. Since the winning probability of cherry in this embodiment is about 1/56, it is difficult for the player to predict how long the specific winning type high probability state will continue, and for each game in the specific winning type high probability state, By letting the player demonstrate a certain level of skill, if the player does not aim to display a combination of cherry symbols, the specific winning type high probability state will continue, and the specific winning type high You can enjoy the game in the probability state.

(Modification 2)
It is good also as content which falls when a specific small combination (for example, cherry) is elected as an end condition, changing to a specific winning kind high probability state by 1/2 of a specific small combination (for example, watermelon) winning. As in the first modification, the watermelon is a small role that has a high possibility of being missed by each reel arrangement and has a low winning probability (in this embodiment, approximately 1/164). Therefore, the player plays each game The goal is to win the watermelon by demonstrating the skill, and the regular game can always have an interest in the lottery for changing the specific winning type probability. Further, if the falling lottery is performed at the time of cherry winning described in the first modification, it is possible to make various developments from a normal game to a game in a specific winning type high probability state.

(Modification 3)
When a combination of BB symbols is displayed, the content may be shifted to the specific winning type high probability state. However, if the game in the specific winning type high probability state is performed 40 times as an end condition, it is ended. Furthermore, a continuous lottery is performed at the end of the game in the specific winning type high probability state (for example, at the 40th game in the specific winning type high probability state), and if the lottery is won, another 40 times in the specific winning type high probability state It is good also as a form which continues a game. The number of games in the specific winning type high probability state and the number of games in the specific winning type high probability state after winning the continuous lottery are not particularly limited to 40 times. Instead of increasing the number of times, a specific winning type probability changing lottery may be performed at the time of first win. As a further modification of this example, the specific winning combination (for example, bell) may end the specific winning type high probability state when the symbol combination is displayed a predetermined number of times (for example, 20 times) or when the symbol combination is displayed. Good.

  Further, in the present embodiment, only BB is set as a target with high probability by changing the specific winning type probability, but another example in which a plurality of specific symbols (BB, RB) are set to high probability will be described below.

(Example 1)
Also in another example 1, since this embodiment, BB, RB, specific winning kind probability change lottery, and its continuation rate are the same, explanation is omitted.

Tables 7 and 8 show the range of the winning value of the random number lottery of another embodiment 1. Table 7 shows a normal game, and Table 8 shows a game in a specific winning type high probability state. Here, it is assumed that in addition to BB and replay, RB also has a high probability (10 times the normal game) in the specific winning type high probability state. The random value lottery value table is not shown.

  FIG. 22 is a flowchart illustrating the determination process according to the first embodiment. Here, since it becomes a form added to the same content as the content demonstrated in the said embodiment, the same content is abbreviate | omitted and the newly added content is demonstrated. When the RB symbol is displayed as a combination in step S1003, a specific winning type probability changing lottery is performed (step S1010 (a)). The subsequent specific winning type probability changing process has the same contents as FIG.

  In this different embodiment 1, not only when the combination of BB symbols is displayed, but also when the combination of RB symbols is displayed, the specific winning type probability change lottery is received. Opportunities to shift to the state will increase, and various developments can be expected in the progress of the game. Especially in slot machines, the machine value is clearly different depending on the setting value (for example, 1 to 6). Therefore, it is almost impossible to enjoy playing games in BB games and RB games. In this case, the game nature and fun of the game machine cannot be exhibited at all.

  The meanings of the above-mentioned machine splits cannot be generally defined, but the machine splits referred to here are long-term (if they are averaged in units such as one week or one month although they cannot be generally specified) ) Refers to the ratio of paid-out medals and inserted medals (for example, the machine discount of 105% means that 1050 medals are paid out with respect to 1000 medals inserted). In the slot machine according to another embodiment, generally, it is positioned as a bonus (because the number obtained is less than half compared to BB, the number obtained is temporarily increased even when the combination of symbols is displayed. The specific winning type probability changing lottery can be received even from the RB winning prize which was only a specific symbol). This increases the value (positioning) that the RB has in the game. Further, if the player shifts to the specific winning type high probability state at the time of winning the RB, and a high continuation rate is selected at that time, the number of acquired coins can be greatly increased. Therefore, even if the setting is low, it is possible to play with a sense of expectation of transition from a normal game to a game in a specific winning type high probability state.

  The above is the description of one embodiment, but the embodiment of the present invention is not limited to this. In particular, regarding the specific symbols constituting the special gaming state, in each of the above-described embodiments, the example in which the BB and the RB are configured has been described. However, the present invention is not limited to this, for example, only the BB and SB, the BB, and the RB only. , BB, RB, and SB.
