Description

  The present invention relates to a gaming machine such as a pachinko gaming machine or a revolving game machine in which a random number value is acquired at a predetermined timing during a game and a lottery is performed based on the random number value.

  In general, a pachinko gaming machine or a swing type gaming machine is provided with random number generating means using pseudo-random numbers. The random number generation means acquires a numerical value at a predetermined timing during a game, and treats the acquired numerical value as a random value, thereby sending it to a CPU on a main control board that controls the game content. The main control board performs a lottery process based on the random number value. In this lottery process, the main control board determines whether or not the random number value corresponds to a predetermined winning value, thereby determining whether or not (or winning / unwinning). For example, in the case of a pachinko gaming machine, if the lottery result is a win, the main control board shifts the gaming machine to a gaming state advantageous to the player. Also, in the case of a spinning-type game machine, if the lottery result is a winning of a predetermined role, the main control board can easily align the symbols corresponding to the role when the player stops the reel. Such reel control is performed.

  FIG. 13 is a schematic block diagram of a random number generation means and a main control board in a conventional spinning machine. As shown in FIG. 13, the random number generation means 110 includes a crystal oscillator 111, a random number counter 112, and a latch circuit 113. The crystal oscillator 111 generates a clock signal having a frequency of 10 MHz, for example. The random number counter 112 repeatedly counts the number of input clock signals within a predetermined range every time the clock signal generated by the crystal oscillator 111 is input. Here, for example, a 16-bit hardware random number counter is used as the random number counter 112, and the count value of the random number counter 112 varies in the range from 0 to 65535. The latch circuit 113 acquires and holds the count value of the random number counter 112 as a random value at the timing when the start lever is operated by the player. Specifically, the latch circuit 113 acquires a random value when receiving a signal from the start lever operation detection sensor 120 that detects that the start lever has been operated. The random value held by the latch circuit 113 is sent to the main control board 130.

  Further, as shown in FIG. 13, the main control board 130 includes a ROM 131, a RAM 132, and a CPU 133. A partial area of the RAM 132 is used as a random value memory that stores the random value sent from the random number generator 110. The ROM 131 stores a hand table showing the correspondence between random values and hands. Here, for example, the range of random values (0 to 65535) is divided into eight winning areas, and a hand table showing the correspondence between random values and winning combinations is stored in the ROM 131 for each winning area. FIG. 14 shows an example of a hand table showing the correspondence between random numbers and hands used in the conventional spinning-type game machine. However, FIG. 14 shows only the hand table used in the general game other than the big bonus game or the regular bonus game. Based on the combination table stored in the ROM 131, the CPU 133 determines which winning area the random number value sent from the random number generation means 110 belongs to, and determines whether the combination has been won or not. .

  As described above, only one table showing the correspondence between the random number value and the winning value or the outlier is used, but recently, a pachinko gaming machine having a plurality of tables has also been proposed (for example, patent literature). 1). This pachinko gaming machine includes a plurality of random number tables with different temporal occurrence probability distributions of winning random numbers and a designation means for designating one random number table from among the plurality of random number tables. For this reason, the game hall manager can change the temporal occurrence probability distribution of the hit random number value by switching the random number table using the designation means.

  By the way, the random number counter 112 always counts the number of clock signals repeatedly within a predetermined range at the input timing of the clock signals. For this reason, theoretically, in the random number counter 112, the count value corresponding to the winning random number value regularly appears as time passes. In particular, in a rotating type gaming machine, the random number value is acquired when the player operates the start lever. Therefore, by matching the time interval for operating the start lever with the time from when the random number counter 112 counts a certain count value until the same count value is counted, the same random number value is always taken into the main control board 130. It becomes possible to be made. That is, the player can play a game by predicting the lottery result. This will lose the fun of gaming.

  Further, it can be said that the spinning-type gaming machine is more easily captured than the pachinko gaming machine in that a random value is acquired when the player operates the start lever. In fact, there is a person who plays a game using a bodily sensation device for operating the start lever at regular time intervals and wins a medal illegally. This body sensation device, for example, generates a signal at a constant rhythm and makes the user feel the signal. A person who has received a signal from the body sensor can operate the start lever at regular intervals by operating the start lever in accordance with the signal. Therefore, it is desired to realize a gaming machine that can effectively prevent an illegal act of aiming at a specific lottery result using such a sensory device or the like.

  In addition, it is also considered that an illegal act of aiming at a specific lottery result can be prevented by applying the technique described in Patent Document 1 described above to the spinning-type game machine. However, even if such a technique is used, if the time interval for switching the random number table is sufficiently longer than the average start lever operation interval, the random number counter Since the counting operation is performed at a constant input timing of the clock signal, it is not possible to effectively prevent the above illegal acts.

FIG. 1 is a schematic front view of a gaming machine according to a first embodiment of the present invention, FIG. 2 is a schematic control block diagram of the gaming machine according to the first embodiment, and FIG. 3 is a random number generation means in the gaming machine according to the first embodiment. It is a schematic block diagram of a main control board. Here, a case is considered where the gaming machine is a revolving type gaming machine called a so-called pachislot machine.

  As shown in FIG. 1, the reel 11a, 11b, and 11c, the display window 12, the medal slot 13, the credit number display section 14, and the bet button are located on the front side of the swivel type gaming machine of the first embodiment. 15a, 15b, 15c, winning lines 16a, 16b, 16c, 16d, 16e, an effective line display unit 17, a start lever (start means) 18, stop buttons 19a, 19b, 19c, and a payout number display unit 21 A medal discharge port 22, a medal tray 23, an image display unit 24, an electrical decoration display unit 25, and a speaker 26.

  In addition to each of the above-described components, the spinning cylinder type gaming machine includes an inserted medal detection sensor 51, bet button operation detection sensors 52a, 52b, and 52c, and a start lever operation detection sensor as shown in FIG. 53, stop button operation detection sensors 54a, 54b, 54c, reel driving means 61a, 61b, 61c, random number generating means 70, a main control board 80, and a peripheral control board 90.

  As shown in FIG. 1, three reels 11a, 11b, and 11c are disposed slightly above the central portion of the swivel type gaming machine. Each reel 11a, 11b, 11c is a rotating drum having a symbol row in which a plurality of symbols are arranged in a row, and is configured to be rotatable. The three reels 11a, 11b, and 11c are driven by reel driving means 61a, 61b, and 61c, respectively. Here, as the reel driving means 61a, 61b, 61c, for example, a stepping motor is used. The reel drive means 61a, 61b, 61c is controlled by the main control board 80.

  The symbols arranged on the reels 11a, 11b, and 11c include, for example, a red numeral “7” symbol, a blue numeral “7” symbol, a replay symbol, a METEOR symbol, a eggplant symbol, a bell symbol, a cherry symbol, and the like. . A total of 21 of these symbols are arranged on the outer periphery of each reel 11a, 11b, 11c. Further, the number of symbols and the arrangement order of symbols differ for each reel 11a, 11b, 11c.

  The display window 12 is a transparent window provided at a position corresponding to the reels 11a, 11b, and 11c. The player can visually check the three symbols attached to the reels 11a, 11b, and 11c from the display window 12 when the reels 11a, 11b, and 11c are stopped.

  The medal slot 13 is an slot for a player to insert a medal. The inserted medal detection sensor 51 is provided inside the medal insertion slot 13 and detects that a medal has been inserted into the medal insertion slot 13. A detection signal from the inserted medal detection sensor 51 is sent to the main control board 80.

  The credit number display unit 14 displays the credit number of medals within a predetermined range. For example, the maximum number of credits can be displayed up to 50. When a medal is inserted from the medal insertion slot 13, the main control board 80, based on a signal from the inserted medal detection sensor 51, increases the number of credits added from the current number of credits by the number of inserted medals. To display. Further, when a predetermined combination is established in the game, the main control board 80 adds the number of medals to be paid out corresponding to the combination to the current credit number, and displays the added number on the credit number display unit 14. Let

  The bet buttons 15 a, 15 b and 15 c are provided on the lower left side of the display window 12. The bet button 15a is a button for selecting to play a game with one medal, the bet button 15b is a button for selecting to play a game with two medals, and the bet button 15c is a medal. This is a button for selecting to play a game with three bets. The bet button operation detection sensors 52a, 52b, and 52c detect that the bet buttons 15a, 15b, and 15c are pressed, respectively. Detection signals from the respective bet button operation detection sensors 52a, 52b, and 52c are sent to the main control board 80. As a result, the main control board 80 can recognize how many medals are bet to play the game.

  In the display window 12, five winning lines 16a, 16b, 16c, 16d and 16e are drawn. Among these, the three winning lines 16a, 16b, and 16c are parallel to each other and extend in the lateral direction. The winning line 16d extends from the upper left to the lower right, and the winning line 16e extends from the lower left to the upper right. The winning lines 16 d and 16 e intersect at the center of the display window 12. When the three reels 11a, 11b, and 11c are stopped, when a predetermined symbol is aligned on a valid winning line among these winning lines 16a, 16b, 16c, 16d, and 16e and a predetermined combination is established, the game is played. A prize is won and a predetermined number of medals are paid out.

  An effective line display unit 17 is provided on the left side of the display window 12. The effective line display unit 17 is for notifying the player of the number of effective winning lines that will be awarded when predetermined symbols are arranged on the winning line in the game. Specifically, when the bet button 15 a is pressed, the main control board 80 lights “1MEDAL” on the active line display unit 17. In this case, only the winning line 16a extending in the lateral direction in the center of the display window 12 is an effective winning line. When the bet button 15b is pressed, the main control board 80 turns on “2MEDALS” in the active line display unit 17. In this case, the three winning lines 16a, 16b and 16c are effective winning lines. When the bet button 15c is pressed, the main control board 80 lights “3MEDALS” in the active line display unit 17. In this case, the five pay lines 16a, 16b, 16c, 16d, and 16e are all valid pay lines.

  The start lever 18 is operated by the player to instruct to start the game. Here, one game starts when the start lever 18 is operated, and ends when all the three stop buttons 19a, 19b, and 19c are pressed. The start lever operation detection sensor 53 detects that the start lever 18 has been operated. When the start lever operation detection sensor 53 detects that the start lever 18 has been operated, it sends a game start signal to the random number generating means 70 and the main control board 80. When the random number generation means 70 receives the game start signal from the start lever operation detection sensor 53, the random number generation means 70 acquires one random number value and sends the acquired random number value to the main control board 80. Further, when receiving a game start signal from the start lever operation detection sensor 53 while receiving a signal from any of the bet button operation detection sensors 52a, 52b, 52c, the main control board 80 performs a game start process. . Specifically, the main control board 80 performs a lottery process for a role based on the random number value sent from the random number generating means 70 and starts rotating the three reels 11a, 11b, and 11c.

  The stop buttons 19a, 19b, and 19c are for stopping the rotation operations of the reels 11a, 11b, and 11c, respectively. The stop button operation detection sensors 54a, 54b, and 54c detect that the stop buttons 19a, 19b, and 19c are pressed, respectively. Detection signals from the respective stop button operation detection sensors 54 a, 54 b and 54 c are sent to the main control board 80. Thereby, the main control board 80 can recognize which stop button has been pressed by the player. When the main control board 80 receives the detection signals from the stop button operation detection sensors 54a, 54b, 54c, the main control board 80 stops the rotation operation of the reel corresponding to the stop button operation detection sensor.

  In this way, after the player operates the start lever 18 and the three reels 11a, 11b, and 11c start rotating, the player presses the stop buttons 19a, 19b, and 19c, whereby the reels 11a, 11b, 11c stops. At this time, if the symbols attached to the reels 11a, 11b, and 11c become a specific combination on an effective pay line, a winning combination is established.

  The types of roles are roughly divided into major roles (bonus) and small roles. For example, in the case of a big player, for example, when the red and blue number “7” symbols are aligned on an effective winning line, the big bonus (BB), which is the role when the symbols are aligned on the effective winning line, and the METEOR symbol are aligned on an effective winning line. There is a regular bonus (RB) that is a role. When becoming a major player, the spinning-type gaming machine shifts to a gaming state advantageous to the player. For example, when BB is established, 15 medals are paid out, and the player enters a BB game where the player can obtain the most medals. Further, when RB is established, 15 medals are paid out and, after the BB game, the player enters an RB game where a large number of medals can be obtained.

  On the other hand, a small combination is a combination when, for example, a eggplant symbol or a bell symbol is aligned on an effective winning line. When such a small combination is established, a predetermined number of medals are paid out. In addition, there is a small role of so-called single cherry, so-called horn cherry. The single cherry small role is when the cherry pattern stops at the position on the left side of the effective winning line 16a when “1MEDAL” or “3MEDALS” on the active line display portion 17 is lit. In the case where “2 MEDALS” on the active line display portion 17 is lit, it means a small part when the cherry symbol is stopped at any position on the left side of the effective pay lines 16a, 16b, 16c. is there. Also, the small cherry corner is a small size when the cherry symbol is stopped at the left position of one of the valid winning lines 16b and 16c when “3MEDALS” on the active line display portion 17 is lit. It is a role. That is, in the small cherry small combination, two single cherry small combinations are formed in the effective winning lines 16b and 16d or in the effective winning lines 16c and 16e. A predetermined number of medals are also paid out when a small cherry or a small cherry is formed. In addition, there is a role when the replay symbols are aligned on an effective winning line. When this combination is established, a replay, that is, the same number of medals as the bet on the current game is automatically inserted, and the player can play the game again without inserting a new medal. .

  The number-of-payout display unit 21 displays the number of medals to be paid out in accordance with the winning combination. The payout number display unit 21 is controlled by the main control board 80. When the number of credits exceeds 50, the surplus medals are released from the medal release port 22, and when a clearing button (not shown) is operated, the number of medals corresponding to the credit number at that time is displayed. Released. The medal tray 23 is a tray for accumulating medals discharged from the medal discharge port 22.

  The image display unit 24 is provided on the right side of the display window 12. For example, a liquid crystal display device is used as the image display unit 24. The image display unit 24 variably displays images such as a plurality of numbers and figures, thereby performing advance notice of winning combination, notification of predetermined information, and other effects. The control of the image display unit 24 is performed by the peripheral control board 90 based on a command from the main control board 80.

  The electrical display unit 25 is provided on the upper part of the spinning cylinder game machine. The electrical display unit 25 is composed of a large number of lamps, LEDs, and the like, and notifies various game states and produces a game effect. When the main control board 80 sends a predetermined command to the peripheral control board 90 according to the progress of the game or the like, the peripheral control board 90 controls the electrical display unit 25.

  The speaker 26 produces a game with sound. When the main control board 80 sends a predetermined command to the peripheral control board 90 according to the progress of the game, the peripheral control board 90 controls the speaker 26.

  The random number generating means 70, the main control board 80, and the peripheral control board 90 are attached to the inside of the rotating type game machine. The peripheral control board 90 is connected to the main control board 80 via a communication cable line.

  The random number generation means 70 sequentially generates a numerical value within a predetermined range, acquires the numerical value as a random value at a timing when a game start signal is received from the start lever operation detection sensor 53, and uses the acquired random value as the main control board. 80. As shown in FIG. 3, the random number generation means 70 includes a crystal oscillator (oscillation means) 71, a random number counter (counting means) 72, and a latch circuit (holding means) 73. The crystal oscillator 71 generates a clock signal having a frequency of 10 MHz, for example.

  The random number counter 72 repeatedly counts the number of input clock signals within a predetermined range every time a clock signal is input. Here, for example, a 16-bit hardware random number counter is used as the random number counter 72, and the count value of the random number counter 72 varies in the range from 0 to 65535. Specifically, the random number counter 72 sequentially increments the count value at the timing when the clock signal is input. When the count value of the random number counter 72 reaches the maximum value (65535), when the clock signal is next input to the random number counter 72, the count value of the random number counter 72 returns to zero.

  The latch circuit 73 acquires and holds the count value of the random number counter 72 as a random value at a predetermined timing. A game start signal from the start lever operation detection sensor 53 is input to the latch circuit 73. The latch circuit 73 acquires the count value of the random number counter 72 when receiving the game start signal from the start lever operation detection sensor 53. The random number value held by the latch circuit 73 is sent to the main control board 80 and temporarily stored in the RAM of the main control board 80.

  The main control board 80 mainly controls and manages game contents and medal payout. Further, the main control board 80 performs a lottery process for a combination. The lottery process for this role will be described in detail later. The main control board 80 sends a predetermined command to the peripheral control board 90 according to the lottery result.

  Further, the main control board 80 performs reel control for driving and stopping the reels 11a, 11b, and 11c. The reel control of the main control board 80 includes, for example, reel drive start control and reel drive stop control, as well as, for example, reel pull-in control that is performed when a winning combination is won, and detachment that is performed when a winning combination is not achieved. There is control etc.

  The reel pull-in control refers to drawing a symbol on an effective winning line when a symbol constituting the role exists within a predetermined number of frames (for example, four frames) from the timing when the stop button is pressed. In this way, the stop position of the reel is controlled. However, if there is no symbol that constitutes the relevant role within the range of the predetermined number of frames at the timing when the player presses the stop button, the reel pull-in control does not work, and the winning symbol is effective. Stop on line. Accordingly, at this time, the symbols constituting the winning combination are not aligned on the effective winning line, and the winning combination is not established.

  The off control means that the stop position of the reel is controlled so that no combination is established in the effective winning line. Therefore, in this case, even if the player presses the stop button aiming at a specific combination, no combination is established and the game result is lost.

  The peripheral control board 90 mainly implements functions related to game effects. That is, the peripheral control board 90 controls the image display unit 24, the electrical decoration display unit 25, and the speaker 26. The peripheral control board 90 receives a command from the main control board 80 and executes a predetermined process.

  Specifically, when the peripheral control board 90 receives a predetermined command from the main control board 80, the peripheral control board 90 determines the content of the game effect based on the command, and the image display unit 24, the electrical display unit 25, and the speaker 26, image production pattern data, electrical production production pattern data, and audio data are sent to 26, respectively. Thereby, the image display unit 24 displays an image based on the image effect pattern data, and the electrical display unit 25 turns on the lamp and the LED based on the electrical effect pattern data. In addition, the speaker 26 outputs a predetermined sound and performs a game effect.

  Next, the configuration of the main control board 80 in the swivel type gaming machine of the first embodiment will be described in detail. Here, FIG. 3 shows only the control system performed by the main control board 80 related to the role lottery process.

  As shown in FIG. 3, the main control board 80 includes a ROM 81, a RAM 82, a CPU (game control means) 83, a random value comparison means (detection means) 84, a change means 85, and a lottery means 86. ing.

  The ROM 81 has a definition pattern storage area 811 for storing a plurality of patterns of definition data defining a correspondence relationship between random numbers and roles in a table format, and a random value threshold storage area 812 for storing threshold data for random values to be described later. And a program storage area (not shown) for storing various programs necessary for game control. The definition pattern storage area 811 stores eight types of definition data patterns in a table format. FIG. 4 is a diagram for explaining patterns of eight definition data stored in the ROM 81. In the present embodiment, as shown in FIG. 4, eight patterns from pattern 1 to pattern 8 are stored. As shown in FIG. 4, each pattern divides a random value of 0 to 65535 into eight winning areas (0 to 7), and defines the correspondence between the random value and the combination.

  In pattern 1, the range of random values from 0 to 47335 (47336 ways) is the winning area “0” (unauthorized), and the range of random values from 47336 to 47485 (150 ways) is the winning area “1” (RB). The range of random values from 47486 to 47757 (272) is the winning area “2” (BB), and the range of random values from 47758 to 53757 (6000) is the winning area “3” (Bell), 53758 to 62735. Random value range (8978) to winning area "4" (replay), random value range from 62736 to 63035 (300) to winning area "5" (corner cherry), 63036 to 65035 Random value range (2000) in winning area “6” (single cherry) and random value from 65036 to 65535 Range (Street 500) are the winning area "7" (eggplant).

  The pattern 2 is obtained by moving the illegal combination of the pattern 1 to a position after the RB, and the range of the random number value of the RB and the illegal selection is changed according to this movement. The rest is the same as pattern 1. The pattern 3 is obtained by moving the illegal combination of the pattern 2 to a position after the BB, and the range of the random number value of the BB and the illegal selection is changed according to this movement. Similarly, each pattern after pattern 4 is created by sequentially shifting the position of the unjustified role of the previous pattern. Therefore, according to the first embodiment, eight patterns can be easily created.

  Each pattern described above is used in general games other than BB games and RB games. In addition, each pattern can be used in BB games and in a normal well-known spinning-type game machine. It also has data that defines the correspondence between random numbers used in RB games and roles, but in the first embodiment, data for BB games and RB games are omitted in order to simplify the explanation. Yes.

  The RAM 82 stores the current random number value storage area 821 for storing the random number value held in the latch circuit 73 of the random number generation means 70, the previous random number value storage area 822 for storing the random number value at the previous game, and the current game. It has a pattern number storage area 823 for storing pattern numbers of definition data to be used, and a work area (not shown) for temporarily storing data. Here, the current random value storage area 821 and the previous random value storage area 822 correspond to the random value storage means of the present invention.

  The random value comparison means 84 obtains the difference between the current random value stored in the current random value storage area 821 of the RAM 82 and the previous random value stored in the previous random value storage area 822, The threshold value stored in the random value threshold storage area 812 of the ROM 81 is compared, and a signal is output when the difference is smaller than the threshold value. That is, when the difference between the current random number value and the previous random number value is smaller than the threshold value, the random value comparing means 84 determines that the gaming state has become a predetermined state, and outputs a predetermined signal.

  The changing unit 85 changes the pattern of definition data used so far when the random value comparing unit 84 outputs a predetermined signal. For example, when pattern 1 has been used, the next pattern 2 or the previous pattern 8 is changed. Alternatively, a simple random number generation circuit may be used to select one pattern with an equal probability from the other seven patterns excluding the currently used pattern. Further, the changing means 85 stores the changed pattern number in the pattern number storage area 823 of the RAM 82 and issues a signal indicating the end of processing. Note that the changing means 85 also issues a processing end signal even when the pattern number is not changed.

  The lottery means 86 determines whether the random number value currently stored in the random number value storage area 821 is a predetermined winning value or outlier when the changing means 85 issues a processing end signal. Is to do. Specifically, the lottery means 86 wins the winning combination by examining which winning area the random value belongs to based on one pattern of definition data stored in the definition pattern storage area 811 of the ROM 81. Determine whether you won or not. The lottery result of the lottery means 86 is sent to the CPU 83.

  The CPU 83 executes game programs stored in the ROM 81 to control game contents. For example, the CPU 83 performs reel control for driving and stopping the reels 11a, 11b, and 11c. In addition to reel drive start control and reel drive stop control, for example, the above-described reel pull-in control that is performed when a winning combination is won, and the reel control of the CPU 83 is performed when the winning combination is not won. There is a detachment control. Further, the CPU 83 sends a predetermined command to the peripheral control board 90 according to the lottery result of the lottery means 86.

  In addition, various standards have been established for the spinning machine. For example, if 4.1 seconds have not elapsed since the start lever 18 was operated, the reels 11a, 11b, and 11c do not rotate even if the start lever 18 is operated next. For this reason, the CPU 83 of the main control board 80 performs drive start control of the reels 11a, 11b, and 11c so as to conform to the standard. However, even if the start lever 18 is operated next within 4.1 seconds after the start lever 18 is operated, the CPU 83 of the main control board 80 detects any of the bet button operation detection sensors 52a, 52b, 52c. If a signal has already been received, lottery processing by the lottery means 84 is performed.

  Next, the procedure of the lottery process performed by the main control board 80 in the rotary type gaming machine of the first embodiment will be described. FIG. 5 is a flowchart for explaining the procedure of the lottery process performed by the main control board 80 in the rotary type gaming machine of the first embodiment.

  When the player presses the start lever 18, the start lever operation detection sensor 53 sends a signal to the CPU 83 and the latch circuit 73. When receiving this signal, the latch circuit 73 collects and holds a random value from the 16-bit random number counter 72. On the other hand, when receiving this signal, the CPU 83 starts the lottery process shown in FIG. In step S <b> 1, the CPU 83 stores the random number value held in the latch circuit 73 in the current random number value storage area 821 of the RAM 82. Note that the random number value obtained in the previous game is stored in the previous random value storage area 822.

  Next, the random value comparison means 84 collects the current random value from the current random value storage area 821 (S2) and collects the previous random value from the previous random value storage area 822 (S3). Further, the difference between the collected random number value of this time and the previous random number value is calculated (S4). Next, the calculated difference is compared with the threshold value stored in the random value threshold storage area 812, it is determined whether the difference is less than the threshold value, and a signal indicating the result is output. (S5).

  When the random number comparison means 84 determines that the value is less than the threshold value and outputs a signal to that effect, the process proceeds to step S6, and the changing means 85 uses the definition data pattern to be used when performing the lottery process. The pattern is changed from the pattern (for example, pattern 1) to the other remaining pattern (any one of patterns 2 to 8) by the method described above. The changed pattern number is stored in the pattern number storage area 823 by the changing means 85.

  In step S7, the lottery means 86 determines the current winning combination by using the pattern number definition data stored in the pattern number storage area 823 for the random value stored in the current random value storage area 821. To do. Finally, the CPU 83 stores the random value stored in the current random value storage area 821 in the previous random value storage area 822 (S8). If it is determined in step S5 that the calculated difference is equal to or larger than the threshold value, the process moves to step S7 and the above-described winning combination is determined without performing the process in step S6. This is the end of the lottery process performed by the main control board 80 in the rotary gaming machine of the first embodiment.

  In the first embodiment, as a random value threshold stored in the random value threshold storage area 812, other lotteries other than unfair election (RB, BB, Bell, replay, square cherry, single cherry, eggplant) The smallest value in the range of random numbers or the smallest value in the range of random values of major players such as RB and BB is used. In the case of the first embodiment, in any case, the threshold value is RB 150 as shown in FIG. However, depending on the type of the revolving type gaming machine, for example, even if the winning combination is won, the winning combination is stocked on the main control board instead of immediately reducing the winning combination, for example, a predetermined condition such as In a so-called ST machine (stock time machine) that collects and returns the winning prizes that have been stocked when a certain small role appears a predetermined number of times, a specification for canceling the stock status from the range of random numbers of the major role There is a case where the range of random values of the small role is small. In this case, the threshold value is a range of random numbers of the small role. Thus, the threshold for random numbers used in the first embodiment is determined according to the type of gaming machine.

  Since the random number generated by the random number generating means 70 is generated by using the random number counter 72, when 65535 is counted, it returns to 0 and is counted again. Therefore, the generated random value has periodicity. For this reason, it is also possible for the player to generate a random number of similar winning combinations in each game by an unauthorized gaming method. In this case, the player will always win. In particular, when the difference between the current random number value and the previous random number value is within 150, there is a high probability that the player is cheating. On the other hand, even if the player does not intend, only the same random number of outliers may be generated for each game. In this case, the player will always lose. On the other hand, according to the swivel type gaming machine of the first embodiment, when the difference between the previous random number value and the current random number value is smaller than a predetermined threshold value, the pattern of definition data to be used is changed. Generation of such a biased random value can be prevented. Therefore, even when a random number is generated using a random number counter, it is possible to provide a game rich in change by eliminating the periodicity of the winning random number value and correcting the winning bias. In addition, it is possible to reliably prevent fraudulent activity using a sensory device or the like.

  In the first embodiment, the case where the gaming machine is a spinning type gaming machine has been described. However, the present invention is not limited to the spinning type gaming machine, and the gaming machine is a pachinko gaming machine. May be.

  In the first embodiment, the case where the detection unit is a random number comparison unit has been described. However, the present invention is not limited to this, and the detection unit is configured to detect the previous random number value and the current random value. Random value continuous comparison means that emits a signal when a state in which a difference from a numerical value is smaller than a predetermined random value threshold is continued a predetermined number of times may be used.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a schematic block diagram of random number generation means and a main control board in the gaming machine according to the second embodiment of the present invention.

  The gaming machine of the second embodiment is different from that of the first embodiment in that the ROM 81 is provided with a measured value threshold storage area 813 instead of the random value threshold storage area 812, and the RAM 82 has a previous random value storage area 822. Instead, the current measurement value storage area 824 and the previous measurement value storage area 825 are provided, the count value comparison means 84a is provided instead of the random value comparison means 84, and the measurement means 87 is newly provided. Other points are the same as in the first embodiment. Therefore, in the second embodiment, those having the same functions as those of the first embodiment are denoted by the same reference numerals or corresponding reference numerals, and detailed description thereof is omitted. In the second embodiment as well, consider a case where the gaming machine is a so-called pachislot machine called a pachislot machine.

  Next, the configuration of the main control board 80a in the swivel type gaming machine of the second embodiment will be described in detail. Here, FIG. 6 shows only the control system performed by the main control board 80a related to the role lottery process.

  As shown in FIG. 6, the main control board 80a includes a ROM 81, a RAM 82, a CPU (game control means) 83, a measured value comparison means (detection means) 84a, a change means 85, a lottery means 86, and a measurement. Means 87.

  The ROM 81 has a definition pattern storage area 811 for storing a plurality of patterns of definition data for defining the correspondence between random values and roles in a table format, and a threshold value storage area for count values 813 for storing threshold value data for count values described later. And a program storage area (not shown) for storing various programs necessary for game control.

  The RAM 82 stores a random number value storage area 821 for storing a random number value held in the latch circuit 73 of the random number generation means 70, a pattern number storage area 823 for storing a pattern number of definition data used in the current game, and a later-described RAM 82. The present measurement value storage area 824 for storing the measurement value measured this time by the measuring means 87, the previous measurement value storage area 825 for storing the measurement value previously measured by the measurement means 87, and data are temporarily stored. And a work area (not shown). Here, the current measurement value storage area 824 and the previous measurement value storage area 825 correspond to the measurement value storage means of the present invention.

  The measuring means 87 measures the time from when the signal from the previous start lever operation detection sensor 53 is received to when the signal from the current start lever operation detection sensor 53 is received. That is, the measuring means 87 measures the interval at which the start lever 18 is pushed down. The measurement value of the measurement means 87 is stored in the current measurement value storage area 824 of the RAM 82. The measuring means 84 always keeps measuring when the gaming machine body is powered on.

  The measured value comparing means 84a calculates the difference between the current measured value stored in the current measured value storage area 824 of the RAM 82 and the previous measured value stored in the previous measured value storage area 825, and the difference between the measured value and the ROM 81 is calculated. The measured value threshold value stored in the measured value threshold value storage area 813 is compared, and a signal indicating the result is output. That is, when the difference between the current measurement value and the previous measurement value is smaller than the threshold value, the measurement value comparison unit 84a determines that the gaming state has become a predetermined state, and outputs a predetermined signal.

  The changing unit 85 changes the pattern of definition data used so far to another pattern when the measurement value comparing unit 84a outputs a predetermined signal. Other points are the same as the changing means of the first embodiment. The extraction means 86 is the same as that in the first embodiment.

  Next, a lottery processing procedure performed by the main control board 80a in the spinning cylinder type game machine of the second embodiment will be described. FIG. 7 is a flow chart for explaining the lottery process performed by the main control board 80a in the spinning cylinder type game machine of the second embodiment.

  When the player presses the start lever 18, the start lever operation detection sensor 53 sends a signal to the CPU 83 and the latch circuit 73. When receiving this signal, the latch circuit 73 collects and holds a random value from the 16-bit random number counter 72. On the other hand, when receiving this signal, the CPU 83 starts the lottery process shown in FIG. In step S <b> 11, the CPU 83 stores the random number value held in the latch circuit 73 in the current random number value storage area 821 of the RAM 82.

  Next, the measurement value comparison unit 84a collects the current measurement value measured by the measurement unit 87 from the current measurement value storage region 824 (S12), and collects the previous measurement value from the previous measurement value storage region 825 (S13). ). Also, the difference between the collected current measurement value and the previous measurement value is calculated (S14). Next, the calculated difference is compared with the measurement value threshold value stored in the measurement value threshold value storage area 813 to determine whether or not the difference is less than the threshold value, and the result is shown. A signal is output (S15).

  When the measured value comparing means 84a determines that the measured value is less than the threshold value and outputs a signal to that effect, the process proceeds to step S16, and the changing means 85 uses the definition data pattern used when the lottery process is performed. The pattern is changed from the pattern (for example, pattern 1) to the other remaining pattern (any one of patterns 2 to 8) by the method described above. The changed pattern number is stored in the pattern number storage area 823 by the changing means 85.

  In step S17, the lottery means 86 determines the current winning combination using the pattern number definition data stored in the pattern number storage area 823 for the random value stored in the current random value storage area 821. To do. Finally, the CPU 83 stores the measurement value stored in the current measurement value storage area 824 in the previous measurement value storage area 825 (S18). If it is determined in step S15 that the calculated difference is greater than or equal to the threshold, the process moves to step S17 and the above-described winning combination is determined without performing the process in step S16. With the above, the lottery process performed by the main control board 80a in the rotary gaming machine of the second embodiment is completed.

  Note that the threshold value for the measurement value used in the second embodiment is determined in consideration of the frequency of the crystal oscillator of the random number generation means, the range of the hit area of the definition data, and the like. Considering the frequency of the crystal oscillator, the period in which the same random number value is generated is determined according to the frequency of the crystal oscillator, and if the start lever is pressed at an interval corresponding to this period, a winning combination is generated continuously It is because it becomes possible to make it. In particular, since the hit area of BB or RB is generally small, by changing the threshold value based on these hit areas, the pattern of definition data to be used can be changed when BB or RB is shot. , BB or RB can always be varied. As a result, it is possible to reliably prevent the BB or RB from being aimed, to ensure irregularity of the game content, and to improve the interest of the game. That is, in the case of this embodiment, this threshold value can be determined based on the frequency of the crystal oscillator of each device or the hit area of the role that has a particularly large effect when it is shot, depending on the model of the revolving game machine. desirable.

  The gaming machine of the second embodiment has the same operation and effect as the first embodiment by changing the pattern of the definition data when the difference between the current measurement value and the previous measurement value is smaller than a predetermined threshold value. Play.

  In the second embodiment, the case where the detection unit is the measurement value comparison unit has been described. However, the present invention is not limited to this, and the detection unit is configured to measure the previous measurement value and the current measurement value. It may be a measured value continuous comparison means that outputs a signal when a state where the difference from the value is smaller than a threshold value continues for a predetermined number of times.

[Third embodiment]
Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 8 is a schematic block diagram of random number generation means and a main control board in the gaming machine according to the third embodiment of the present invention.

  The gaming machine of the third embodiment is different from that of the first embodiment in that the ROM 81 is provided with a game number threshold storage area 814 instead of the random value threshold storage area 812, and the RAM 82 has a previous random value storage area 822. Instead, a game number storage area 826 is provided, a game number comparison means 84b is provided instead of the random value comparison means 84, and a game number counting means 88 is newly provided. Other points are the same as in the first embodiment. Therefore, in the third embodiment, those having the same functions as those of the first embodiment are denoted by the same reference numerals or corresponding reference numerals, and detailed description thereof is omitted. In the third embodiment, a case where the gaming machine is a so-called pachislot machine called a pachislot machine is considered.

  Next, the configuration of the main control board 80b in the swivel type gaming machine of the third embodiment will be described in detail. Here, FIG. 8 shows only the control system performed by the main control board 80b related to the lottery process.

  As shown in FIG. 8, the main control board 80b includes a ROM 81, a RAM 82, a CPU (game control means) 83, a game number comparison means (detection means) 84a, a change means 85, a lottery means 86, and the number of games. And counting means 88.

  The ROM 81 has a definition pattern storage area 811 for storing a plurality of patterns of definition data for defining the correspondence between random numbers and roles in a table format, and a game number threshold storage area 814 for storing game number threshold data, which will be described later. And a program storage area (not shown) for storing various programs necessary for game control.

  The RAM 82 stores a random number value storage area 821 for storing a random number value held in the latch circuit 73 of the random number generation means 70, a pattern number storage area 823 for storing a pattern number of definition data used in the current game, and a later-described RAM 82. A game number storage area 826 for storing data of the number of games counted by the game number counting means 88 and a work area (not shown) for temporarily storing data.

  The game number counting means 88 counts the number of games by performing a process of adding 1 each time a signal is received from the start lever operation detection sensor 53 that detects that the start lever 18 is pressed. The counted game number data is stored in the game number storage area 826 of the RAM 82.

  The number-of-games comparison means 84b compares the number of games stored in the number-of-games storage area 826 of the RAM 82 with the threshold value for the number of games stored in the threshold value storage area 814 for the number of games in the ROM 81, and outputs a signal indicating the result. Output. That is, when the number of games stored in the number-of-games storage area 826 is equal to or greater than the threshold value, the game number comparison unit 84b determines that the game state has reached a predetermined state and outputs a predetermined signal.

  The changing means 85 changes the pattern of definition data used so far to another pattern when the game number comparing means 84b outputs a predetermined signal. Other points are the same as the changing means of the first embodiment. The extraction means 86 is the same as that in the first embodiment.

  Next, the lottery processing procedure performed by the main control board 80b in the spinning cylinder game machine of the third embodiment will be described. FIG. 9 is a flowchart for explaining a lottery process performed by the main control board 80b in the spinning-reel game machine of the third embodiment.

  When the player presses the start lever 18, the start lever operation detection sensor 53 sends a signal to the CPU 83 and the latch circuit 73. When receiving this signal, the latch circuit 73 collects and holds a random value from the 16-bit random number counter 72. On the other hand, when receiving this signal, the CPU 83 starts the lottery process shown in FIG. In step S 21, the CPU 83 stores the random number value held in the latch circuit 73 in the current random number value storage area 821 of the RAM 82.

  Next, the game number comparing means 84b collects the game number data counted by the game number counting means 88 from the game number storage area 826 of the RAM 82 (S22). Further, the collected number of games is compared with the threshold value for the number of games stored in the threshold value storage area 814 for the number of games, and it is determined whether or not the collected number of games is equal to or greater than the threshold value. The signal shown is output (S23).

  When the number-of-games comparing means 84b determines that the number is more than the threshold value and outputs a signal to that effect, the process proceeds to step S24, and the changing means 85 currently uses the pattern of definition data used when performing the lottery process. The pattern is changed from the existing pattern (for example, pattern 1) to the other remaining pattern (any one of patterns 2 to 8) by the method described above. The changed pattern number is stored in the pattern number storage area 823 by the changing means 85.

  In step S25, the lottery means 86 determines the current winning combination using the pattern number definition data stored in the pattern number storage area 823 for the random value stored in the current random value storage area 821. To do. If it is determined in step S23 that the number of games collected is smaller than the threshold, the process moves to step S25 and the above-described winning combination is determined without performing step S24. With the above, the lottery process performed by the main control board 80b in the rotary gaming machine of the third embodiment is completed.

  The threshold for the number of games used in the third embodiment may be 1 or an integer value of 2 or more. This threshold value is determined in consideration of the range of the hit area of the definition data. In the case of the present embodiment, in particular, it is possible to prevent irregularities in the game by preventing a role with a wide hit area from being shot except for BB and RB. Therefore, it is desirable to determine this threshold value based on the wide role of the hit area of each swirl type gaming machine.

  The gaming machine of the third embodiment has the same operations and effects as the first embodiment by changing the definition data pattern when the number of games exceeds a predetermined threshold.

[Fourth embodiment]

Other points are the same as in the first embodiment. Accordingly, in the fourth embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals or corresponding reference numerals, and detailed description thereof is omitted. In the fourth embodiment as well, consider a case where the gaming machine is a so-called pachislot machine called a pachislot machine.

  Next, the configuration of the main control board 80c in the swivel type gaming machine of the fourth embodiment will be described in detail. Here, FIG. 10 shows only the control system performed by the main control board 80c related to the role lottery process.

It should be noted that the number of medals to be paid out by the gaming machine is counted, and the number of paid-out medal counting means stored in the paid-out medal number storage area 828 and the number of medals inserted by the player are counted and stored in the inserted medal number storage area 829. Since the inserted medal counting means is known, its detailed description is omitted. In addition, the data in the RAM 82 stored in the medal payout number storage area 828, the inserted medal number storage area 829, and the like is held by a backup power supply (not shown) even after the gaming machine is turned off.

  The game number counting means 88 performs a process of adding 1 each time the main control board 80c receives a signal from the start lever operation detection sensor 53 that detects that the start lever 18 has been pressed. Count the number of times. The counted game number data is stored in the game number storage area 826 of the RAM 82.

In the case of “50”). If they match, a signal to that effect is output. After the game number confirmation means 89 outputs a signal indicating that they match, the CPU 83 resets the number of games counted by the game number counting means 88 to 0 and prepares for the next 50 counts.

  The current payout rate calculating means 100 is the latest predetermined number of times (for example, 400 times, 6000 times, or 17500 times) every game, that is, every time the main control board 80c receives a signal from the start lever operation detection sensor 53. ) To calculate the current payout rate, which is the ratio of the number of payouts with respect to the number of game media inserted in the game, and stores the result in the current payout rate storage area 827.

  The payout rate comparison means 84c compares the current payout rate stored in the current payout rate storage area 827 of the RAM 82 with the threshold for the payout rate stored in the threshold value threshold value storage area 815 of the ROM 81. Then, a signal indicating the result is output. In other words, the payout rate comparison means 84c is configured such that the payout rate stored in the current payout rate storage area 827 reaches two predetermined threshold values (55% and 120% in the present embodiment). For example, when it exceeds 120% or falls below 55%, it is determined that the gaming state has reached a predetermined state, and a predetermined signal is output.

  The changing means 85 changes the pattern of definition data used so far by lottery when the payout rate comparing means 84c outputs a predetermined signal. For example, using a simple random number generation circuit, one pattern is selected with an equal probability from the other seven patterns excluding the currently used pattern. Further, the changing means 85 stores the changed pattern number in the pattern number storage area 823 of the RAM 82 and issues a signal indicating the end of processing. The extraction means 86 is the same as that of the first embodiment.

  Next, the payout rate of this embodiment will be described. The game play rate of a gaming machine can be expressed by the following equation.

      Outgoing rate (%) = {(Number of medals paid out) ÷ (Number of inserted medals)} x 100

  The payout rate can be set in six stages 1 to 6 for each gaming machine by a payout rate setting switch provided in each gaming machine. This set value is designed so that the payout rate increases in order from the set value 1. Normally, a gaming machine set to the setting value 1 or 2 is called a low setting gaming machine, a gaming machine set to the setting value 3 or 4 is a middle setting gaming machine, and a gaming machine set to the setting value 5 or 6 The machine is called a high setting gaming machine. When a hall is newly opened, most gaming machines are set to a high setting of 5 or 6 so that a player can easily win a prize medal. In this way, in the hall, the setting of the payout rate of each gaming machine is changed almost every day according to the business policy of the day.

  The gaming machine of this embodiment is designed so that the payout rate is in the range of 55% to 120% so that an appropriate number of prize medals can be paid out. However, when a gaming machine designed as such is installed in a hall and actually used, the payout rate may be greater than 120% or conversely, may be smaller than 55%. If the number of gaming machines in such a state increases in the hall, the business policy intended by the hall cannot be realized.

  FIG. 11 is a diagram for explaining the change of the pattern of the definition data according to the actual payout rate. In the present embodiment, as shown in FIG. 11, when the actual payout rate is in the range from 55% to 120%, the payout rate is appropriate, so the pattern of the definition data is not changed. On the other hand, when the actual payout rate is greater than 120%, it is highly likely that the player has illegally won a large number of medals using a bodily sensation machine or the like. Even if no fraud has been performed, the player depresses the start lever 18 at regular intervals, so that the winning area is frequently selected and the actual payout rate exceeds the designed payout rate. It ’s in an overrun condition. In order to prevent such illegal acts and excessive numbers, when the payout rate is greater than 120%, the definition data pattern used is changed to another definition data pattern.

  In addition, when the player presses the start lever 18 at a low timing and frequently selects the wrong area, the actual payout rate becomes smaller than the designed payout rate of 55%, and there are insufficient shortages. It often becomes the state of. Therefore, in the present embodiment, in order to prevent such a shortage state, the definition data pattern used is changed to another definition data pattern even when the payout rate becomes smaller than 55%. I have decided. As a result, even if the player presses the start lever at a bad timing, the pattern of the definition data to be referred to changes, so that it is possible to avoid a state in which the wrongly selected area is frequently selected. That is, in this embodiment, when the payout rate is outside the range from 55% to 120%, the payout rate is 55 by changing the pattern of the definition data being used to another definition data pattern. It is controlled to be in the range of% to 120%.

  Next, a lottery process performed by the main control board 80c in the spinning-reel game machine of the fourth embodiment will be described. FIG. 12 is a flowchart for explaining the procedure of the lottery process performed by the main control board 80c in the rotating game machine of the fourth embodiment.

  When the player depresses the start lever 18, the start lever operation detection sensor 53 sends a signal to the main control board 80 c and the latch circuit 73. When receiving this signal, the latch circuit 73 collects and holds a random value from the 16-bit random number counter 72. On the other hand, when receiving this signal, the CPU 83 starts the lottery process shown in FIG. In step S 31, the CPU 83 stores the random number value held in the latch circuit 73 in the current random number value storage area 821 of the RAM 82.

  In step S 32, the current payout rate calculating means 100 determines the payout medal number data stored in the payout medal number storage area 828 of the RAM 82 and the inserted medal number data stored in the inserted medal number storage area 829. Is used to calculate a current new payout rate, and the result is stored in the current payout rate storage area 827 of the RAM 82 as the current payout rate. As described above, in this embodiment, every time a game is received, that is, every time a signal is received from the start lever operation detection sensor 53, the current payout rate calculating means 100 calculates the payout rate, and the result is obtained as a current value. Stored in the payout rate storage area 827. In step S33, every time the game number counting means 88 receives a signal from the start lever operation detection sensor 53, 1 is added to the number of games, and the result is stored in the game number storage area 826 of the RAM 82.

  Next, the number-of-games checking means 89 obtains the specified number-of-games data (“50” in the present embodiment) from the specified number-of-games storage area 816 of the ROM 83 (S34), Number data is acquired (S35). In step S36, the game number confirmation means 89 compares the acquired data on the designated game number with the game number data, and determines whether or not the game number has reached the designated game number. When the number of games is smaller than the designated number of games (50 times), the process moves to step S41 without changing the definition data table, and the lottery means 86 stores the random value stored in the current random value storage area 821. The winning combination of this time is determined using the pattern number definition data stored in the pattern number storage area 823.

  On the other hand, if it is determined in step S36 that the number of games matches the designated number of games (50), the CPU 83 counts the number of games counted by the game number counting means 88 in preparation for the next 50 counts. Is reset to 0. Further, the payout rate comparison means 84c acquires the current payout rate data from the current payout rate storage area 827 of the RAM 82 (S37), and the output rate threshold value from the output area of the output rate threshold of the ROM 83 815. (In this embodiment, “55%” and “120%”) are acquired (S38). The payout rate comparison means 84c compares the acquired current payout rate with a threshold of the payout rate, and determines whether or not the acquired current payout rate is in the range from the threshold value 55% to 120%. And a signal indicating the result is output (S39). In this way, when the number of games reaches the designated number of games (50 times), it is a certain amount of time to calculate the payout rate and determine whether the calculated payout rate is within a predetermined threshold range. This is because the playing rate does not change unless the number of games is played. The designated number of games is not limited to 50 times.

  When the current payout rate is within the range from the threshold value 55% to 120%, the payout rate comparing means 84c determines that if a signal to that effect is output, the process proceeds to step S41 without changing the definition data pattern. Then, the winning combination determination process described above is performed.

  On the other hand, if the current payout rate is greater than the threshold value of 120%, the payout rate comparing means 84c determines that when a signal to that effect is output, the process proceeds to step S40. In step S40, the changing means 85 changes the pattern of the definition data used when performing the lottery process from the currently used pattern (for example, pattern 1) to the remaining other patterns (pattern 2 to pattern 8). Any one) is changed by the method described above. The changed pattern number is stored in the pattern number storage area 823 by the changing means 85. In step S41, the lottery means 86 uses the pattern number definition data after the change stored in the pattern number storage area 823 for the random value stored in the current random value storage area 821, and the current winning combination To decide.

  Also, in step S39, when the current payout rate is smaller than the threshold 55%, the payout rate comparing means 84c determines that when a signal to that effect is output, the process proceeds to step S40. The same process as when the payout rate is greater than the threshold value of 120% is performed. That is, after changing from the currently used pattern (for example, pattern 1) to the other remaining pattern (any one of patterns 2 to 8), the winning combination determining process is performed. With the above, the lottery process performed by the main control board 80c in the swivel game machine of the fourth embodiment is completed.

  In the gaming machine of the fourth embodiment described above, when the payout rate is out of the predetermined threshold range, the control of the payout rate that the conventional game machine could not perform by changing the pattern of the definition data It can be performed. Other actions and effects are the same as in the first embodiment.

  In addition, the threshold of the game play rate used in the fourth embodiment may be a separate threshold for each of the low setting gaming machine, the medium setting gaming machine, and the high setting gaming machine. Good. Thereby, it is possible to control the payout rate according to the low setting, the medium setting, and the high setting. Moreover, you may make it use a separate threshold value for every setting value of the setting values 1-6 mentioned above as the threshold value of a payout rate. For example, when the set value is 1, the output rate is 95%, when the set value is 2, the output rate is 99%, when the set value is 3, the output rate is 103%, and when the set value is 4, the output rate is 107%, when the set value is 5, the output rate is 111%, and when the set value is 6, the output rate is 116%. The threshold range of the output rate is the plus or minus of each set value. It may be set in a stepwise manner so as to be in the range of 3%, and the pattern may be changed when it is outside this range. Thereby, it becomes possible to control the payout rate according to the payout rate of each set value for each set value. In the fourth embodiment, the case where the pattern of the definition data is changed when the payout rate is outside the range of 55% to 120% has been described. In order to prevent unauthorized actions or excessive medals, the definition data pattern may be changed only when the payout rate exceeds a predetermined threshold (120%).

  In the fourth embodiment, the case where the game number coefficient means, the game number storage area, the designated game number storage area, and the game number confirmation means are provided has been described, but the present invention is not limited to this. These patterns may be omitted, and the pattern of the definition data may be changed by determining whether or not the current payout rate is within a predetermined threshold range for each game.
