Description

  The present invention relates to a ball-type game machine such as a pachinko machine or an arrangement ball machine that uses a game ball to play a game.

  Currently, in game machines such as pachinko machines, various fraudulent acts are performed by some unskilled players. As the types of fraudulent acts on pachinko machines, for example, fraudulent acts that illegally win a game ball at a prize opening using a piano wire, etc., variable start ports using a piano wire, etc. (ordinary electric equipment) There are fraudulent acts that illegally win game balls, so-called fraudulent acts called radio wave goto, fraudulent acts called so-called magnet goto, and the like.

  An illegal act of illegally winning a game ball in a grand prize opening using a piano wire or the like is an act of forcibly opening the special prize opening by inserting a piano wire into the inside through a gap of a frame body such as a front frame. It is. In addition, when there is no gap in the frame, it means an act of forcibly opening the grand prize opening by making a hole in the upper plate or the like with a soldering iron and inserting a piano wire from there.

  The fraudulent act of illegally winning a game ball at a variable start port (ordinary electric accessory) using a piano wire or the like is a variable type in which a piano wire is inserted into the inside through a gap of a frame body such as a front frame. This is an act of forcibly opening the starting port. Further, when there is no gap in the frame body, it means an act of forcibly opening a variable start port by making a hole in an upper plate or the like with a soldering iron and inserting a piano wire into the hole from there.

  The so-called fraudulent act referred to as radio wave goto refers to an act of illegally transmitting a radio signal related to a winning signal at the start opening from the outside of the pachinko machine and illegally generating a special game state (so-called jackpot game state).

  The so-called fraudulent act called magnet goto is particularly performed for a pachinko machine having a so-called V prize opening (meaning a prize opening where a big hit game is generated when winning a prize). Is a fraudulent act in which a game ball that has been launched is attached to a magnet and guided to a V prize opening to win a prize.

  Here, in the current pachinko machine, various illegal acts described above may be executed, and when such an illegal act is executed, a warning sound for notifying that the illegal act has occurred is generated. It was output and a warning was displayed. In addition, when an illegal act is detected, the result of the internal lottery is invalidated.

  By the way, in order to establish a fraudulent act as a criminal act, it is necessary to provide evidence of the fraudulent act. In order to secure evidence of this fraudulent activity, hall officials and security guards rush to pachinko machines that output warning sounds and display warnings, and the fraudulent behavior of the player who is cheating itself It is necessary to withstand.

JP 2003-340115 A JP 2008-43606 A

  However, if the hall officials or security guards do not immediately rush to the pachinko machine that outputs the warning sound or displays the warning sound, it is defined as a fraudster (“player who is cheating”. ) Escapes or aborts the cheating, making it impossible to get evidence of the cheating. Also, even if a hall official or guard who rushed to the scene of fraudulent attempts to suppress the fraud alone alone, the risk is that the fraudster will rampage and the hall personnel or guard will be injured unexpectedly There is also sex.

  Therefore, an object of the present invention is to provide a gaming machine that can easily secure a player who performs a fraudulent act and its evidence (facts and state of the fraudulent act) compared to a conventional machine.

According to the first aspect of the present invention, a main control means for acquiring a random number value by random number lottery processing, determining whether or not is correct, and designating a pattern variation pattern corresponding to the success or failure, and an incoming ball into which a game ball enters Fraud detection means for detecting an illegal act of illegally entering a game ball into the mouth, and the fluctuation pattern designated by the main control means when the fraud detection means detects the illegal action; A special control means for changing to a special fluctuation pattern different from the above, and a fluctuation display of a symbol based on the fluctuation pattern or the special fluctuation pattern, and when the fraud detection means detects the fraud A symbol display means for variably displaying a symbol based on the special fluctuation pattern changed by the special control means instead of the fluctuation pattern designated by the control means; A storage unit that stores a plurality of variation patterns and a variation pattern group including the special variation patterns having different results of time and success / failure lottery, wherein the main control unit stores the storage unit in the storage unit The variation pattern corresponding to the success / failure is selected from the variation pattern group that has been determined, and the special control unit selects the special variation pattern to be changed from the variation pattern group stored in the storage unit. The special control means, when the fraud detection means detects the fraud, the special fluctuation that the fluctuation time becomes the longest out of the fluctuation pattern group and the result of the lottery decision is out When a pattern is selected and the symbol based on the variation pattern is changing when the fraud detection means detects the fraud, the main control It outputs the command signal specifying the change start timing of the symbols based on the special variation pattern, the symbol the contents of the command signal is the fraud detection means based on the variation pattern at the time of detecting the abuse It changes according to the elapsed time from the start of fluctuation .

According to the first aspect of the present invention, the special control means changes the fluctuation pattern designated by the main control means to a special fluctuation pattern by the special control means when an illegal act is detected by the fraud detection means. . Then, the symbol display unit executes the symbol variation display based on the special variation pattern changed by the special control unit instead of the variation pattern designated by the main control unit. The fraudster (player) who has seen the symbol variation display by the special variation pattern is not a normal symbol variation, and thus continues the game while paying attention to the symbol variation. As a result, time can be saved, so that necessary and sufficient hall personnel and guards can be arranged. As a result, it is possible to safely and reliably catch an unauthorized person. In addition, it is possible to prevent a fraudster from attempting to destroy evidence of fraud. Thereby, evidence of fraud can be left. The “symbol” means to include both a so-called main symbol and a so-called pseudo symbol of a special symbol.
When a fraudulent act is detected by the fraud detection means, the special control means selects a special variation pattern having the longest variation time from the variation pattern group and the result of the lottery lottery is off. Thereby, since the variation time of the special variation pattern becomes longer, more time can be saved. In addition, since the result of the lottery determination is lost as a result of the symbol variation due to the special variation pattern, it is possible to prevent the occurrence of a gaming state advantageous to the fraudster. As a result, it is possible to reliably and safely catch the cheating person and to prevent the cheating person from performing the prize ball payout process.
When the symbol based on the variation pattern is changing when the fraud detection unit detects the fraud, the main control unit outputs a command signal specifying the variation start timing of the symbol based on the special variation pattern By changing the content of the command signal according to the elapsed time from the start of the pattern variation based on the variation pattern when the fraud detection means detects fraud, the variation of the symbol based on the special variation pattern is It can correspond to the progress of the game. As a result, it is possible to prevent the sense of incongruity of the pattern game from occurring, and it is possible to prevent the disappearance of evidence of fraud and escape.

According to a second aspect of the present invention, in the first aspect of the present invention, the symbol display means has a plurality of variable symbol display areas, and the main control means detects the fraud by the fraud detection means. The command signal designating the variation start timing of the symbol based on the special variation pattern based on the variation / stop mode of the symbol that is variably displayed or stopped in the plurality of variation display areas of the symbol display means Is output .

According to the second aspect of the present invention, the main control means changes / stops the symbols that are variably displayed or stopped in the plurality of variable display areas of the symbol display means when the fraud detection means detects fraud. Based on the aspect, by outputting the command signal designating the symbol variation start timing based on the special variation pattern, it is possible to suppress the occurrence of a sense of discomfort in the game.

  ADVANTAGE OF THE INVENTION According to this invention, the player who performs fraudulent act and its evidence (the fact and state of fraudulent act) can be ensured reliably and safely.

It consists of three symbol display areas consisting of a left symbol display area. Each symbol display area has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction). Each symbol display area can display symbols consisting of “0” to “9”. The pseudo symbol starts the variable display when the variable display of the main symbol is started. When the main symbol is stopped and displayed with any of the symbols, the pseudo symbol is stopped and displayed with a symbol corresponding to the main symbol. The pseudo design corresponds to the identification design of the present invention.

  In the pseudo symbol, the combination of the same three-digit symbols is a big hit symbol corresponding to the normal big hit symbol (Fig. 7 (b)) of this symbol or the combination of the probable big hit symbol (Fig. 7 (c)) of this symbol, Other combinations of the pseudo symbols are the out symbols corresponding to the out symbol of this symbol (FIG. 7A). In the pseudo symbol, a plurality of types of combinations of normal jackpot symbols and probability variation jackpot symbols are set. Specifically, the combination of the regular jackpot symbol of the pseudo symbol is a combination of even symbols (“0 · 0 · 0”, “2 · 2 · 2”, “4 · 4 · 4”, “6”) that are three digits identical.・ 6 ・ 6 」,「 8 ・ 8 ・ 8 」), and the odd-numbered symbols (“ 1 ・ 1 ・ 1 ”,“ 3 ・ 3 ・ 3 ”) are the same in 3 digits. ”,“ 5 · 5 · 5 ”,“ 7 · 7 · 7 ”,“ 9 · 9 · 9 ”). The determination of the variation pattern of the pseudo symbol and the stop symbol is performed by the sub-control unit 260 based on a command transmitted from the main control unit 200 (hereinafter, “transmission” is expressed as “output” as appropriate). Has been.

  In the gaming machine according to the present embodiment, after the special gaming state is finished, a specific game (so-called time-short game and probability variable game) in which the variable time shortening function, the open time extending function, and the probability varying function are started. When this symbol is normally displayed as a big-hit symbol, after the special gaming state is finished, the variable time shortening function and the open time extending function are activated to be in a short time state. When this symbol is displayed in a stopped state with a probable big hit symbol, after the special gaming state is finished, the variation time shortening function and the open time extension function are activated, and the probability variation function is activated to enter the certainty variation state.

  The short time state is realized by the control of the main control unit 200, and the main control unit 200 functions as a variable time shortening means for operating the variable time shortening function and an open time for operating the open time extending function. A function as an extension means. The variation time shortening function includes a normal symbol variation time shortening function for shortening the normal symbol variation time and a special symbol variation time shortening function for shortening the special symbol variation time. The fluctuation time shortening function and the opening time extension function are the time until the next condition device is actuated after the operation of the accessory continuous actuating device or until the number of times the symbol fluctuates reaches a predetermined number (100 in this example). It works until.

  The probability variation state is realized by the control of the main control unit 200, and the main control unit 200 has a function as a probability variation unit that operates the probability variation function. In the probability variation state, in addition to the above-described variation time shortening function and opening time extension function, a probability variation function that changes (improves) the probability of the special symbol success / failure determination, that is, the probability that the special symbol is stopped and displayed as a big hit symbol is activated. The probability variation function operates until the next condition device is activated after the end of the operation of the accessory continuous activation device or until the number of variations of the symbol reaches a predetermined number (10000 in this example).

  Here, the opening time extension function for extending the opening time of the lower start port (ordinary electric accessory) 28b will be described. The opening time of the lower start port (ordinary electric accessory) 28b is a predetermined time (for example, 0.1 second) when the open time extension function is not operated, and the lower start port is set when the open time extension function is operated. The opening time of (ordinary electric accessory) 28b is extended. When the opening time extension function is activated, a plurality of opening patterns of the lower start opening (ordinary electric accessory) 28b are set, and the opening times of the lower starting opening (ordinary electric accessory) 28b are different in each opening pattern. ing. In the present embodiment, the first opening pattern in which the opening time of the lower start port (ordinary electric accessory) 28b is 6 seconds and the second opening in which the opening time of the lower start port (ordinary electric accessory) 28b is 3 seconds. Pattern is set. These release patterns are stored in the ROM of the main control unit 200, and the ROM of the main control unit 200 corresponds to the release pattern storage means of the present invention.

  These multiple types of release patterns are selected based on the type of stop symbol of the special symbol that generates the special game state that causes the release time extension function to operate. In this embodiment, when the special symbol is a probable big hit symbol, that is, when the probability variation function is activated (probability variation state), when the special symbol is a normal big hit symbol, that is, the fluctuation time shortening function and the opening time. Compared with the case where the shortening function is activated (time-short state), an opening pattern in which the opening time of the lower start opening (ordinary electric accessory) 28b is long is selected. For this reason, when the special symbol is a probable big hit symbol, that is, when the pseudo symbol is an odd symbol having the same three digits, the first opening pattern (opening time: 6 seconds) is set. When the special symbol is a normal jackpot symbol, that is, when the pseudo symbol is a combination of even numbers with the same three digits, the opening time of the lower start port (ordinary electric accessory) 28b is shorter than the first opening pattern. 2 Opening pattern (opening time: 3 seconds) is set. These opening pattern selection processes are configured to be performed under the control of the main control unit 200, and the main control unit 200 corresponds to the opening pattern selection means of the present invention.

  Next, the electronic control device of the gaming machine 1 of this embodiment will be described with reference to FIG. FIG. 9 is a block diagram illustrating a schematic configuration of the electronic control device.

  As shown in FIG. 9, the electronic control unit includes a main control unit 200 and sub-control units 230, 260, and 280 connected to the main control unit 200. The sub control unit includes a prize ball control unit (payout control unit) 230, a sub control unit 260, and an effect display control unit 280. The main control unit 200 includes a main control board 200a, and the sub control units 230, 260, and 280 include a payout control board 230a, a sub control board 260a, and an effect display control board 280a, respectively, as peripheral control boards.

  The main control unit 200 is responsible for the progress of the game, and transmits a command signal (command data) instructing the processing contents to each of the sub control units 230, 260 and 280, and each of the sub control units 230, 260 and 280 Various controls are performed based on the command signal.

  For example, a command such as a prize ball instruction signal for instructing a prize ball payout, a game start permission signal for instructing a game start permission, and various launch control commands are transmitted from the main control unit 200 to the payout control unit 230. Various launch control commands include ball feed permission / prohibition, launch permission / prohibition, game start permission, and the like. Also, various lamp control commands, various audio control commands, and various effect display control commands are transmitted from the main control unit 200 to the sub-control unit 260.

  Each control unit 200, 230, 260, and 280 is supplied with power from the power receiving board 128 connected to the main power source 129 via the power board 127 and the power relay board 121. Further, when the power is turned on, a system reset signal is transmitted to each of the control units 200, 230, 260 and 280 via the power supply board 127 and the power supply relay board 121. Note that the gaming machine 1 of this embodiment includes a backup power supply unit (not shown) that supplies an operating voltage to the main control unit 200 and the payout control unit 230 when the power is turned off. 200 and RAM data of the payout control unit 230 are held.

  The main control board 200a mainly includes a CPU (main control means) 400, a special CPU (special control means) 402, and a ROM (storage means) 404. For this reason, since the main control unit 200 includes the main control board 200a, the main control unit 200 includes the CPU 400, the special CPU 402, and the ROM 404. Note that the CPU 400 and the special CPU 402 may be configured by the same CPU or may be configured by separate CPUs. The CPU 400 and the special CPU 402 may be mounted on the same main control board 200a or may be mounted on separate main control boards.

  The CPU 400 (main control means) includes a CPU core, a built-in RAM (hereinafter also simply referred to as “RAM”), a built-in ROM (hereinafter also simply referred to as “ROM”), etc., and the RAM is controlled by a control program stored in the ROM. As an area, it controls the overall operation of the gaming machine 1 (basic progress control of the game). In addition, the CPU 400 determines whether or not it is correct using a program for determining whether or not it is stored in the ROM. This success / failure determination is executed based on the random value acquired by the random number lottery process. Specifically, the CPU 400 determines the gaming state based on the random value acquired by the random number lottery process. Then, in order to execute the game effect process (game control process) corresponding to the determined gaming state, the main control unit 200 instructs each sub-control unit 230, 260, and 280 with a command signal (command) Data). In order to execute the game effect process (game control process) corresponding to the determined gaming state, the main control unit 200 instructs the board relay board 210 and the symbol display device drive board 211 to specify the processing contents (commands). Data). Note that the control cycle of the main control unit 200 (CPU 400) of this embodiment is set to 4 ms.

  The CPU 400 designates a variation pattern of a normal symbol and a special symbol (including both “main symbol” and “pseudo symbol” to be described later; the same applies hereinafter) corresponding to the gaming state determined by the random number value acquired in the random number lottery process. To do. A plurality of variation patterns of a normal symbol and a special symbol are stored in the ROM 404 as a variation pattern group. Therefore, the CPU 400 selects and designates the variation pattern of the normal symbol and the special symbol corresponding to the determined gaming state from the variation pattern group stored in the ROM 404. Specifically, the CPU 400 selects a variation pattern having a variation time and a game result corresponding to the gaming state as the variation pattern of the normal symbol and the special symbol. The main control unit 200 then issues a command signal (command data) for realizing a game effect (variable display control of normal symbols and special symbols, LED light emission control, sound output control) based on the variation pattern selected by the CPU 400. ) Is output to each of the sub-control units 230, 260, and 280, the board surface relay substrate 210, and the symbol display device drive substrate 211.

  The special CPU 400 (special control means) includes a CPU core, a built-in RAM (hereinafter also simply referred to as RAM), a built-in ROM (hereinafter also simply referred to as ROM), etc., and fraud detection is performed by a control program stored in the ROM. When an illegal act is detected by the means 212, the variation pattern of the special symbol ("main symbol" and "pseudo symbol") designated by the CPU 400 is forcibly changed to a special variation pattern. Note that the variation pattern group stored in the ROM 404 includes a plurality of special variation patterns with different variation times and game results. Therefore, the special CPU 402 selects one special variation pattern from among the variation pattern groups stored in advance in the ROM 404.

  In particular, in the first embodiment, the special variation pattern stored in the ROM 404 is the longest time among the special variation patterns stored in the ROM 404, and the special variation pattern in which the result of the lottery determination is out of the way. It is fixed. For this reason, when an illegal act is detected, the variation pattern designated by the CPU 400 is forcibly changed to the special variation pattern having the above-described characteristics.

  Here, it becomes a problem at what timing to execute a game effect (for example, a change display effect of a special symbol) based on the special change pattern changed from the change pattern. Specifically, if the special symbol is already changing based on the fluctuation pattern designated by the CPU 400 when the fraud is detected, the special symbol based on the fluctuation pattern (this symbol and the pseudo symbol) This variation is executed until it is finished. Then, the variation of the special symbol based on the special variation pattern is started from the start of the variation of the next special symbol. With respect to such timing, a command signal (command data) instructing the start timing of the game effect based on the special variation pattern from the main control board 200a (main control section 200) to the sub control board 260a (sub control section 260). ) Is output and adjusted. Note that LED light emission control and sound output control based on the special variation pattern are also constrained by the start timing in the same manner as the symbol variation.

  In particular, the special symbol pseudo-design start timing based on the special variation pattern is when the special symbol pseudo-design is fluctuating and there are multiple special symbol reserves when cheating is detected. The change display of the pseudo symbol of the special symbol which is currently changing is executed as it is. Then, after the change display of the pseudo symbol of the special symbol that is currently changing is finished, the special change of the pseudo symbol of the special symbol is changed to the change display based on the change pattern of the pseudo symbol of the special symbol for the next number of holdings. Variation display based on the pattern is executed.

  When an illegal act is detected, the main control unit 200 realizes a game effect (special symbol variation display control, LED light emission control, sound output control) based on the special variation pattern changed by the special CPU 402. Command signals (command data) are output to the sub-control units 230, 260 and 280, the board surface relay board 210 and the symbol display device drive board 211. In addition, the main control unit 200 sends command signals (command data) for instructing the start timing of the game effect based on the special variation pattern to the sub-control units 230, 260 and 280, the board relay board 210, and the symbol display device driving board. 211.

  The ROM 404 stores in advance a variation pattern group including a plurality of variation patterns and special variation patterns having different variation times and game results of normal symbols and special symbols. The “variation pattern” is designated by the CPU 400 and is a variation pattern of a normal symbol and a special symbol corresponding to a gaming state determined based on a random value. Further, the “special variation pattern” is designated by the special CPU 402, and a special symbol (“main symbol”) that is forcibly changed from the variation pattern designated by the CPU 400 when an illegal act is detected. And “pseudo symbol”).

  As shown in FIG. 9, the main control unit 200 includes a board external terminal board 201, a start opening ball detection switch 28s, a normal symbol operation gate detection switch 27s, fraud detection means 212, a board surface relay board 210, and a game frame. The relay board 220 is connected. The start opening ball detection switch 28 s detects that a game ball has entered the start opening 28. The normal symbol operation gate detection switch 27 s detects that a game ball has passed through the normal symbol operation gate 27.

  Next, the board surface relay board 210 will be described with reference to FIG. FIG. 10 is a block diagram showing various gaming devices connected to the board surface relay board 210. The board surface relay board 210 relays switch signals and the like between various switches provided on the game board 20 surface and the main control unit 200.

  As shown in FIG. 10, on the board relay board 210, there are a symbol display device driving board 211, winning hole entrance detecting switches 34s, 35s, 36s, 37s, a winning entrance entrance detecting switch 33s, and various solenoids 28d, 33c. It is connected.

  The symbol display device drive board 211 operates the normal symbol display unit 56 and the special symbol display unit 62. The winning opening entrance detection switches 34 s, 35 s, 36 s, and 37 s are used to detect the entry of game balls into the winning openings 34, 35, 36, and 37. The big winning opening entrance detection switch 33s detects that a game ball has entered the big winning opening 33a. These game ball detection switches can be configured by proximity switches or photo sensors. As the various solenoids 28d and 33c, there are a start opening solenoid 28d for opening and closing the lower start opening 28b, a large winning opening solenoid 33c for opening and closing a large winning opening, and the like.

  Here, the symbol display device drive board 211 is configured to store the normal symbol in the normal symbol display unit 56 and the special symbol in the special symbol display unit 62 based on a command signal (command data) output from the main control unit 200. Each symbol is displayed in a variable manner. Specifically, the symbol display device drive board 211 executes the normal symbol variation display based on the variation pattern designated by the CPU 400 of the main control unit 200 in the normal symbol display unit 56. In addition, the symbol display device drive board 211 executes a variation display of the special symbol main symbol based on the variation pattern designated by the CPU 400 of the main control unit 200 in the special symbol display unit 62. In addition, the symbol display device driving board 211 has a special symbol based on the special variation pattern designated by the special CPU 402 (see FIG. 9) of the main control unit 200 at the designated start timing in the special symbol display unit 62. The variable display of this symbol is executed.

  Further, as shown in FIG. 9, the main control unit 200 is forced to change the gaming state determined by the CPU 400 to another gaming state (especially, a gaming state advantageous to the player (a cheating person)). A fraud detector 212 for detecting fraud is connected. The fraud detector 212 may be connected to the board relay board 210.

  A detailed configuration of the fraud detection unit 212 will be described. In this embodiment, the configuration of the fraud detection means 212 differs depending on the type of fraud. As described in the background art, examples of fraudulent acts include, for example, fraudulent acts that illegally enter a game ball into a big prize opening using a piano wire or the like, variable start ports ( There is a fraudulent act that illegally wins a game ball in a normal electric accessory), a fraudulent act called a radio wave goto, a so-called magnet goto, etc. Hereinafter, each type of fraud will be described.

(Unauthorized act of illegally winning a game ball at the grand prize opening using a piano wire, etc.)
This fraudulent act is an act of forcibly opening the grand prize winning opening 33a by inserting a piano wire into the inside through a gap between frames such as the front frame. Further, when there is no gap in the frame body, it means an act of forcibly opening the grand prize winning opening 33a by making a hole in the upper plate part 5 or the like with a soldering iron and inserting a piano wire from there. In this case, if the gaming machine 1 side is not in a special game (for example, during a big hit game) and a winning of a game ball to the big winning opening 33a is detected by the fraud detection means 212, it is considered an illegal act. In other words, the fraud detection means is invalid during the special game (big hit game). However, in the last round of the special game (big hit game) (not based on cheating), after the game ball wins the big prize opening 33a and the open / close plate 33b of the big prize opening 33a is closed, it is illegal. In some cases, the detecting means 212 detects a game ball. Therefore, the invalid time of the fraud detection means 212 is not from the start (first round) to the end (final round) of the special game (big hit game) but the start (first round) of the special game (big hit game). Is controlled by the CPU 400 of the main control board 200a so that a predetermined time (for example, 10 seconds) is added to the time from the start to the end (final round).

  As the fraud detection means 212 used for detecting the fraudulent act, for example, a game ball detection sensor (such as an optical sensor or a contact sensor) for detecting a game ball won in the special winning opening 33a is preferable. The movable time of the game ball detection sensor is controlled by the CPU 400 of the main control board 200a. The game ball is detected only when the game ball detection sensor is in operation, and the game ball cannot be detected during the time when the game ball detection sensor is not in operation. Further, the game ball detection sensor always operates and always detects a game ball. However, the game ball detection may be invalidated during a special game (big hit) and within a predetermined time.

(Unauthorized act of illegally winning a game ball at a variable start opening (ordinary electric accessory) using a piano wire, etc.)
This fraudulent act is an act of forcibly opening a variable start port (corresponding to the lower start port 28b in FIG. 2) by inserting a piano wire into a gap between frames such as the front frame. Further, when there is no gap in the frame, a hole is made in the upper plate 5 or the like with a soldering iron, and a piano wire is inserted from there into the variable start port (corresponding to the lower start port 28b in FIG. 2). ) Is forcibly released. In this case, the variable start port (corresponding to the lower start port 28b in FIG. 2) is not opened in the normal gaming state, and the game ball does not win. In other words, the variable start port (corresponding to the lower start port 28b in FIG. 2) is a normal symbol lottery process (ordinary symbol success / failure determination) in which the game ball starts after passing through the normal symbol operation gate 27. The game ball is opened only when it is won, and the game ball is not won in a normal game state other than the game state. With this type of variable start port (corresponding to the lower start port 28b in FIG. 2), after the normal symbol is won, the variable start port (corresponding to the lower start port 28b in FIG. 2) is opened. When a game ball enters the variable start port (corresponding to the lower start port 28b in FIG. 2) at a time other than the time from the start to the closing, it is determined that there is an abnormality. In the same way as in the case of the big winning opening 33a, even in the case of the variable start opening (corresponding to the lower start opening 28b in FIG. 2), the pair of wing pieces 28c start after the game ball has entered. The mouth (corresponding to the lower start opening 28b in FIG. 2) is closed, and then the game ball may be detected by the fraud detection means. For this reason, the valid time of the fraud detection means 212 is after a lapse of a predetermined time (for example, 5 seconds) after the pair of blade pieces 28c closes the starting port (corresponding to the lower starting port 28b in FIG. 2). As described above, the CPU 400 of the main control board 200a is controlled.

  As the fraud detection means 212 used for detecting the fraud, for example, a game ball for detecting a game ball that has entered a variable start port (corresponding to the lower start port 28b in FIG. 2). A detection sensor (such as an optical sensor or a contact sensor) is preferred. The effective time of the game ball detection sensor is controlled by the CPU 400 of the main control board 200a. The game ball is detected only when the game ball detection sensor is in operation, and the game ball cannot be detected during the time when the game ball detection sensor is not in operation. In addition, the game ball detection sensor is always operated and always detects a game ball, but the game ball detection is disabled until a predetermined time elapses after the variable start port is opened and closed. It is good.

(Illegal acts called so-called radio waves)
Such a fraudulent act illegally transmits a radio wave related to a winning signal at the starting port (corresponding to the lower starting port 28b in FIG. 2) from outside the gaming machine 1, and illegally generates a special gaming state (so-called big hit gaming state). An act.

  For example, a radio wave sensor that detects unauthorized radio waves is used as the fraud detection means 212 used to detect the fraud. By mounting this radio wave sensor on the gaming machine 1, it is possible to detect fraudulent acts related to radio goto.

(Illegal act called magnet goto)
Such fraudulent acts are particularly carried out for gaming machines with so-called V prize opening (meaning a prize opening where a big hit game is generated when winning a prize). This is a fraudulent act in which a game ball is attached to a magnet and guided to a V prize opening to win. In the present embodiment, the illustration of a gaming machine having a so-called V winning opening (meaning a winning opening that generates a big hit game when winning) is omitted.

  For example, a magnet sensor that detects a magnet (such as a magnetic force, a magnetic field, or a magnetic field line) is used as the fraud detection unit 212 used to detect the fraud. By mounting this magnet sensor on the gaming machine 1, it is possible to detect fraudulent acts related to the magnet goto.

  Here, when a fraud is detected by the fraud detection unit 212, a fraud detection signal for indicating the fact of the fraud is output from the fraud detection unit to the CPU 400 and the special CPU 402 of the main control board 200a. At this time, the cheating flag assigned to a predetermined address in the RAM of the CPU 400 is set to ON. The CPU 400 and the special CPU 402 detect fraud by receiving the fraud detection signal. The cheating flag may be assigned to a predetermined address in the RAM of the special CPU 402.

  Here, if no fraud is detected by the fraud detection means 212, a fraud non-detection signal indicating that there is no fraud is output from the fraud detection means to the CPU 400 and the special CPU 402 of the main control board 200a. . At this time, the cheating flag assigned to a predetermined address in the RAM of the CPU 400 is set to OFF. The CPU 400 and the special CPU 402 detect that there is no fraud by receiving the fraud non-detection signal.

The tank ball cut switch 232 is also connected to the frame external terminal board 122.

  The tank ball cut switch 232 detects that the game ball in the prize ball tank 105 has run out. The ball-out signal of the tank ball-out switch 232 is transmitted to the external replenishing device via the frame external terminal board 122, and the game ball is replenished to the prize ball tank 105 from the replenishing device. The lower tray full tank switch 233 detects that the lower tray 6 has become full. The payout control board 230a of the payout control unit 230 includes a CPU having the same configuration as the CPU 400 of the main control board 200a.

  Next, the sub control unit 260 will be described with reference to FIG. FIG. 11 is a block diagram showing various gaming devices connected to the sub-control unit 260. The sub control board 260a provided in the sub control unit 260 is provided with arithmetic circuit components (not shown) having a CPU 262, ROM, RAM, input / output ports and the like and a sound generator (not shown). The port is connected to the main control unit 200.

  As shown in FIG. 11, various board surface LED boards 263, various game frame LED boards 264, and the like are connected to the sub-control unit 260 via a lamp interface board 261. The lamp interface board 261 is provided with a drive circuit for various lamps, and is configured as a separate board independent of the sub-control board 260a. A game effect LED board or the like is connected to the board surface LED board 263 and the game frame LED board 264. These lamps are turned on / off or blinking in accordance with the progress of the game to enhance the gaming effect.

  Further, an amplifier board 265 is connected to the sub-control unit 260. A speaker 266 and a volume switch board 267 are connected to the amplifier board 265. From the speaker 266, various sounds, sounds, and the like are output in accordance with the progress of the game. The volume switch board 267 is for setting the output volume of the speaker 266 in accordance with an operation of a volume switch (not shown).

  Further, the mode control switch 268 and the effect switch 5d are connected to the sub-control unit 260.

The port is connected to the sub-control unit 260.

  As shown in FIG. 12, the effect display control unit 280 is connected to a symbol display device driving board 281 that operates the symbol display device 25. The effect display control unit 280 performs display control of the symbol display device 25 using the RAM as a work area according to a control program stored in the ROM. Display control of the symbol display device 25 by the effect display control unit 280 is performed based on a command from the sub-control unit 260. In addition, the ROM of the effect display control board 280a stores symbol image data for effects displayed on the symbol display device 25.

  Next, the operation of the gaming machine 1 of this embodiment will be described based on the flowcharts of FIGS. FIG. 13 shows an example of a main job executed by the CPU 400 based on a program stored in the ROM of the main control unit 200. The main job shown in FIG. 13 includes a game start process S200, a normal symbol game process S300, a normal electric game game process S400, a special symbol game process S500, and a special electric game game process S600 after executing the power-on process S100. Each step is repeatedly executed every time the timer is reset. In this embodiment, the reset period is set to 4 ms.

  Next, the power-on process S100 executed by the CPU 400 of the main control unit 200 will be described based on the flowchart of FIG. This power-on process is performed when power is turned on and when power is restored after a power failure occurs. First, various settings required when the power is turned on are performed (S101). Specifically, the stack pointer is set to a predetermined address in the RAM, the interrupt mode is set, and access to the RAM is permitted.

  Next, when the RAM clear switch is pressed or when the backup flag (power failure occurrence information) is not set in the RAM, it is determined that the power is turned on and the RAM initialization process is performed. Return (S102, S103, S104). As the RAM initialization processing, initial setting of built-in devices around the CPU is performed, all areas of the RAM are cleared to 0, initial values during normal game are set, and interrupts are permitted. Also, a game start flag is set.

  On the other hand, if the backup flag is set in the RAM, it is determined that the power is restored when the power is turned off, and a checksum is calculated from the contents of the RAM protected when the power is turned off (S105). (S106). If these checksums do not match, it is determined that the contents of the RAM are broken, and the RAM initialization process of S104 is performed. When the contents of the RAM are backed up normally, the following power recovery process is performed.

  First, the stack pointer immediately before power-off is restored and the backup flag is cleared. Next, a return setting is made to return to the gaming state when the power is turned off, the CPU peripheral device is initialized, and the register is returned to the state immediately before the power is turned off. Thereafter, the program is resumed by returning to the program execution position immediately before the power is turned off.

  Next, a game start process S200 executed by the CPU 400 of the main control unit 200 will be described based on the flowchart of FIG. First, all the switches other than the RAM clear switch connected to the main control unit 200 are read (S201), the respective switch states are determined, and the detection information is stored (S202).

  Next, various random numbers such as a random number for determination of success / failure and a random number for symbol display are updated (S203). Specifically, the value of the random number counter set in the above-described RAM is incremented by 1 between an initial value (for example, 0) and a predetermined value (for example, 255). When the value of the random number counter exceeds a predetermined value, the initial value is restored.

  Next, prize ball control in S204 to S207 is performed. First, each winning mouth is checked by a winning mouth switch, and when a game ball wins a winning mouth, winning detection information is stored in the RAM (S204, S205). Next, when there is saved prize ball detection information, a prize ball number designation command corresponding to the acquired game ball is transmitted to the payout control unit 230 (S206, S207).

  Next, the normal symbol game process S300 executed by the CPU 400 of the main control unit 200 will be described based on the flowchart of FIG. First, it is determined by the normal symbol operation gate detection switch 27s whether or not the game ball has passed the normal symbol operation gate 27 (S301). As a result, when it is determined that the game ball has passed through the normal symbol operation gate 27 (S301: YES), it is determined whether or not the number of pending operation of the normal symbol display unit 56 is less than 4 (S302). If the number of normal symbols held is less than 4 (S302: YES), a random number for determining whether or not normal symbols are stored is stored (S303).

  Next, it is determined whether or not the lower start port (ordinary electric accessory) 28b is operating (S304), and if it is determined that the lower start port (normal electric accessory) 28b is operating, (S304: YES), the process returns as it is, and if it is determined that the lower start port (ordinary electric accessory) 28b is not operating (S304: NO), it is determined whether or not the normal symbol is changing ( S305). As a result, when it is determined that the normal symbol is not changing (S305: NO), it is determined whether or not the normal symbol is in the stop display time (S306), and it is determined that the normal symbol is in the normal symbol display time. If this is the case (S306: NO), the process proceeds to S314, which will be described later. If it is determined that the normal symbol display time is not being reached (S306: YES), it is determined whether or not the normal symbol hold count is zero (S306: NO). S307).

  As a result, when it is determined that the number of normal symbol hold is zero (S307: YES), the process returns as it is, and when it is determined that the number of normal symbol hold is not zero (S307: NO), whether or not the normal symbol is determined is determined. (S308) and the normal symbol variation time is set (S309). When the fluctuation time reduction function is active, set the normal symbol fluctuation time when the fluctuation time reduction function is activated.When the fluctuation time reduction function is not active, set the normal symbol fluctuation time when the fluctuation time reduction function is not active. Set. Then, the variation of the normal symbol is started (S310).

  When it is determined in S305 that the normal symbol is changing (S305: YES), it is determined whether or not the normal symbol change time has passed (S311), and the normal symbol change time has passed. If it is determined that there is not (S311: NO), the process directly returns. On the other hand, if it is determined that the normal symbol change time has elapsed (S311: YES), the normal symbol change is stopped (S312), and the normal symbol stop display interval is set (S313).

  Next, it is determined whether or not the interval between the normal symbols has been stopped (S314). If it is determined that the interval between the normal symbols has not been stopped (S314: NO), the process returns as it is. If it is determined that the normal symbol stop display period has elapsed (S314: YES), the normal symbol stop symbol will activate the lower start port (normal electric accessory) 28b. It is determined whether it is a combination (S315). As a result, when it is determined that the stop symbol of the normal symbol is not a winning symbol combination (S315: NO), the process returns as it is.

  When it is determined that the stop symbol of the normal symbol is a combination of the winning symbols (S315: YES), the operating time of the lower start port (ordinary electric accessory) 28b is set (S316). In the process of S316, the opening time of the lower start port (ordinary electric accessory) 28b is set according to the opening pattern of the lower start port (normal electric accessory) 28b set in S614 described later. Specifically, when the opening time extension function is not operating, a predetermined opening time (0.1 second) is set. When the open time extension function is activated and the probability variation function is activated, an open time based on the first open pattern (6 seconds in this embodiment) is set. When the opening time extension function is activated and the probability variation function is not activated, the second opening pattern in which the opening time of the lower start port (ordinary electric accessory) 28b is shorter than the first opening pattern. The opening time based on (3 seconds in this embodiment) is set. As a result, during the specific game in which the open time extension function is activated, the probability of the probability variation function being activated (probability variation state) is lower than that of the probability variation function being deactivated (time-short state) of the lower start port (ordinary electric accessory) 28b. The opening time becomes longer. Then, the operation of the lower start port (ordinary electric accessory) 28b is started (S317).

  Next, the ordinary electric accessory game process S400 executed by the CPU 400 of the main control unit 200 will be described based on the flowchart of FIG. First, it is determined whether or not the lower start port (ordinary electric accessory) 28b is operating (S401), and if it is determined that the lower start port (normal electric accessory) 28b is not operating, (S401: NO), return as it is. On the other hand, if it is determined that the lower start port (ordinary electric accessory) 28b is in operation (S401: YES), whether or not the operating time of the lower start port (normal electric accessory) 28b has elapsed. Is determined (S402), and if it is determined that the operation time of the lower start port (ordinary electric accessory) 28b has not elapsed (S402: NO), the regular electric accessory is awarded the prescribed number of winnings. It is determined whether or not there is (S403).

  As a result, when it is determined that the lower start opening (ordinary electric accessory) 28b does not receive the predetermined number of winnings (S403: NO), the process returns to the lower start opening (ordinary electric accessory) 28b. When it is determined that the specified number of winnings has been won (S403: YES), or when it is determined that the operating time of the lower start port (ordinary electric accessory) 28b has elapsed (S402: YES). Then, the operation of the lower start port (ordinary electric accessory) 28b is stopped (S404).

  Next, the special symbol game process S500 executed by the CPU 400 of the main control unit 200 will be described with reference to the flowcharts of FIGS. First, it is determined whether or not a game ball has been won at the start port 28 (S501). If it is determined that a game ball has been won at the start port 28 (S501: YES), the special symbol display unit 62 is activated. It is determined whether the number of holds is less than 4 (S502). As a result, when it is determined that the number of special symbol hold is less than 4 (S502: YES), a random number for determining whether or not special symbol is determined is stored (S503).

  Next, it is determined whether or not the condition device is operating (S504). Here, the condition device is a device that becomes a condition for operating the accessory continuous operation device, and is a device that starts the operation when the condition for generating the special gaming state is satisfied. The condition device is configured by the CPU of the main control unit 200. Next, when it is determined that the condition device is in operation (in the special gaming state) (S504: YES), the process directly returns, and when it is determined that the condition device is not in operation (S504: NO). ), It is determined whether or not the special symbol is changing (S505). As a result, when it is determined that the special symbol is changing (S505: YES), the process proceeds to S513 described later, and when it is determined that the special symbol is not changing (S505: NO). Then, it is determined whether or not it is during the special symbol stop display time (S506). If it is determined that it is during the special symbol stop display time (S506: YES), the process proceeds to S516 described later, and if it is determined that it is not during the special symbol stop display time (S506: NO). ), It is determined whether or not the number of special symbol hold is zero (S507).

  As a result, when it is determined that the number of special symbol hold is zero (S507: YES), the process returns as it is, and when it is determined that the number of special symbol hold is not zero (S507: NO), the probability variation It is determined whether or not the function is operating (S508). As a result, when it is determined that the probability variation function is in operation (S508: YES), whether or not the probability variation function is correct is determined (S509), and when it is determined that the probability variation function is not in operation. (S508: NO), it is determined whether or not there is a non-probability change (S510).

  Next, a special symbol variation pattern determination process is performed (S511). This special symbol variation pattern defines the variation time of the special symbol and the presence / absence of reach effect in the variation. When the special symbol success / failure determination is a probable big hit, the stop symbol and fluctuation pattern for the probable big hit are determined, and when the special symbol success / failure determination is a normal big hit, the stop symbol and fluctuation pattern for the normal big hit are determined. To do. In other cases, the result of the special symbol success / failure determination is out of order, and the outage stop symbol and its variation pattern are determined according to the presence or absence of the reach effect.

  In particular, in the special symbol variation pattern determination process in S511, the special symbol main symbol and pseudo symbol variation patterns are determined based on the command signal (command data) output from the main control unit 200. The variation pattern at this time is determined based on the random number value acquired by the random number lottery process executed by the CPU 400 of the main control unit 200. As the variation pattern determined in S511, the CPU 400 selects one variation pattern that matches the random value from among the variation pattern group stored in the ROM 404 of the main control unit 200.

  Next, the CPU 400 of the main control unit 200 determines whether or not the fraudulent flag is on (S511A). Here, when the cheating flag is ON, the cheating is detected. When a cheating is detected, the cheating flag assigned to a predetermined address in the RAM of the CPU 400 (or the special CPU 402) is set to ON in the cheating flag setting process described later. When the fraud flag is turned off, the fraud flag assigned to a predetermined address in the RAM of the CPU 400 (or the special CPU 402) in the fraud flag release process is set to off (the fraud flag flag) Release). Such a fraud flag setting process and cancellation process will be described later.

  If the cheating flag is ON (S511A: YES), the special symbol main pattern and the pseudo symbol variation pattern determined in S511 are changed to a special variation pattern (S511B). The change to the special variation pattern is executed by the special CPU 402. The special variation pattern is selected from the variation pattern group stored in the ROM 404 of the main control unit 200, and the one variation pattern whose variation time is the longest time and the result of the lottery determination is out of date is selected. Note that the fluctuation pattern in which the fluctuation time is the longest time and the result of the lottery determination is out of date is a fluctuation pattern in outlier reach. Since it is a variation pattern of super reach with high reliability, the player pays attention to the result of success or failure.

  Next, an effect pattern designation command is output to the sub-control unit 260, and the special symbol variation in the symbol display device 25 is started (S512). The effect pattern designation command is a command for designating the variation pattern determined in S511 or the special variation pattern changed in S511A. Thus, the special symbol display unit 62 displays the special symbol main symbol based on the variation pattern designated by the CPU 400 of the main control unit 200 or the special variation pattern designated by the special CPU 402 at the designated start timing. Fluctuation is displayed. Further, in the symbol display device 25, the special symbol is displayed based on the variation pattern designated by the CPU 400 of the main control unit 200 or the special variation pattern designated by the special CPU 402 at the start timing designated by the main control unit 200. Pseudo symbol is variably displayed.

  If it is determined in S505 that the special symbol is changing (S505: YES), it is determined whether the special symbol change time has elapsed (S513). As a result, when it is determined that the variation time of the special symbol has not elapsed (S513: NO), the process returns as it is, and when it is determined that the variation time of the special symbol has elapsed (S513: YES), the special symbol fluctuation is stopped (S514), and the special symbol stop symbol display time is set (S515).

  Next, it is determined whether or not the special symbol stop symbol display time has elapsed (S516). As a result, when it is determined that the special symbol stop symbol display time has not elapsed (S516: NO), the process returns as it is, and when it is determined that the special symbol stop symbol display time has elapsed. (S516: YES), it is determined whether the stop symbol of the special symbol is a combination of jackpot symbols that will activate the condition device (S517). As a result, when it is determined that the stop symbol of the special symbol is a combination of the big hit symbol (S517: YES), the operation of the condition device is started (S518), and the operation of the accessory continuous operation device is started (S518). S519).

  Next, it is determined whether or not the probability variation function is in operation (S520). If it is determined that the probability variation function is in operation (S520: YES), the probability variation function is deactivated (S521). ), The variable time reduction function is deactivated (S522), and the open time extension function is deactivated (S523).

  If it is determined in S517 that the special symbol stop symbol is not a combination of the big hit symbol (S517: NO), it is determined whether or not the variable time reduction function is in operation (S524). The process of S524 is to determine whether the probability variation function is not activated and only the variation time shortening function (and the open time extension function) is activated. In other words, the current gaming state is the time shortening state. It is determined whether or not there is. As a result of the process of S524, when it is determined that the variable time reduction function is not operating (S524: NO), the process returns as it is, and when it is determined that the variable time reduction function is operating (S524: YES), The number of fluctuations of the special symbol is counted (S525), and it is determined whether or not the number of fluctuations has reached a preset number of fluctuations (100 in this example) (S526). As a result, when it is determined that the number of fluctuations has not reached the preset number of fluctuations (S526: NO), the process returns as it is and it is determined that the number of fluctuations has reached the preset number of fluctuations. In such a case (S526: YES), the variable time shortening function is deactivated (S522), and the open time extending function is deactivated (S523).

  If it is determined in S520 that the probability variation function is not in operation (S520: NO), it is determined whether or not the variation time reduction function is in operation (S527). The process of S527 is to determine whether or not the current gaming state is a short-time state, similar to the process of S524. As a result of the process of S527, when it is determined that the variable time shortening function is not operating (S527: NO), the process returns as it is, and when it is determined that the variable time shortening function is operating (S527: YES), The variable time shortening function is deactivated (S522), and the open time extending function is deactivated (S523).

  Next, the special electric accessory game process S600 executed by the CPU 400 of the main control unit 200 will be described based on the flowchart of FIG. First, it is determined whether or not the accessory continuous operation device is in operation (S601). If it is determined that the accessory continuous operation device is not in operation (S601: NO), the process returns as it is. If it is determined that the continuous operating device is operating (S601: YES), it is determined whether or not the special winning opening 33a is open (S602). As a result, when it is determined that the special winning opening 33a is being opened (S602: YES), it is determined whether or not the opening time (30 seconds in this embodiment) of the special winning opening 33a has elapsed ( S603), when it is determined that the opening time of the big prize opening 33a has not elapsed (S603: NO), the maximum number of game balls in the big prize opening 33a (10 game balls in this embodiment) It is determined whether or not has won a prize (S604).

  As a result, when it is determined that the maximum number of game balls has not been won in the big prize opening 33a (S604: NO), the process returns as it is, and the maximum number of game balls won in the big prize opening 33a. If it is determined that the opening time of the special winning opening 33a has elapsed (S603: YES), the special winning opening 33a is closed (S605).

  If it is determined in S602 that the big prize opening 33a is not open (S602: NO), is the number of continuous operations of the big prize device (special electric accessory) 33 less than a predetermined number of times set in advance? It is determined whether or not (S606). Here, the number of continuous operations indicates the number of times that the special winning opening 33a is continuously opened (becomes in a game ball receiving state), and is the so-called number of rounds. Therefore, in the process of S606, it is determined whether or not the number of continuous operations of the special winning device (special electric accessory) 33 is less than 15. As a result of the process of S606, when it is determined that the number of consecutive operations of the special winning device (special electric accessory) 33 is less than the predetermined number (S606: YES), the closing time of the special winning opening 33a has elapsed. (S607), if it is determined that the closing time of the big prize opening 33a has not passed (S607: NO), the process returns as it is, and the closing time of the big prize opening 33a has passed. If it is determined that it is (S607: YES), the special winning opening 33a is opened (S608).

  When it is determined in S606 that the number of continuous operations of the special winning device (special electric accessory) 33 has reached the predetermined number (S606: NO), the operation of the accessory continuous operation device is stopped (S609). ), The operation of the condition device is stopped (S610). Thereby, the special game state is ended. Then, it is determined whether or not the stop symbol of the special symbol that triggered the activation of the condition device is a combination of probability variation big hit symbols that activate the probability variation function (S611). As a result, when it is determined in the determination process of S611 that the stop symbol of the special symbol is not the probability variation big hit symbol (S611: NO), the process proceeds to S613, and the special symbol stop symbol is the probability change big hit symbol. If it is determined (S611: YES), the probability variation function is activated (S612).

  Next, the operation for shortening the fluctuation time is started (S613), and the start port opening pattern setting process is performed (S614). In the starting port opening pattern setting process, the opening pattern of the lower starting port (ordinary electric accessory) 28b is set based on the type of the hit pattern of the special symbol. Specifically, when the special symbol is a probable big hit symbol, that is, an odd symbol (“1 · 1 · 1”, “3 · 3 · 3”, “5 · 5 · 5”, “ 7 · 7 · 7 ”,“ 9 · 9 · 9 ”), the first opening pattern (opening time: 6 seconds) is set, and the special symbol is a normal jackpot symbol, that is, the pseudo symbol is 3 It is a combination of even numbers with the same digit (“0 • 0 • 0”, “2 • 2 • 2”, “4 • 4 • 4”, “6 • 6 • 6”, “8 • 8 • 8”) In this case, a second opening pattern (opening time: 3 seconds) is set. Then, the activation of the open time extension function is started (S615).

  Next, the fraudulent flag setting process S800 executed by the CPU 400 (or the special CPU 402) of the main control unit 200 will be described with reference to the flowchart of FIG. As shown in FIG. 21, the CPU 400 (or special CPU 402) of the main control unit 200 determines whether an illegal act has occurred (S801). In S <b> 801, when a fraud occurs, a fraud detection signal is output from the fraud detection unit 212 by the CPU 400 and the special CPU 402. The CPU 400 (or the special CPU 402) of the main control unit 200 inputs the fraud detection signal. It is judged that cheating occurred.

  When the occurrence of an illegal act is detected (S801: YES), the CPU 400 (or the special CPU 402) sets the illegal act flag assigned to its own predetermined address to ON (S802). Note that if the occurrence of fraud is not detected (S801: NO), the fraud flag is not set to ON. Also, the fraudulent flag set to ON here is referred to by the CPU 400 or the special CPU 402 in S511A of FIG.

  Next, the fraud flag cancellation process S900 executed by the CPU 400 (or the special CPU 402) of the main control unit 200 will be described with reference to the flowchart of FIG. As shown in FIG. 22, it is determined by the CPU 400 (or the special CPU 402) of the main control unit 200 whether or not the abnormality due to fraud has been canceled (S901). In S <b> 901, when no fraud has occurred, a fraud non-detection signal is output from the fraud detection unit 212 by the CPU 400 and the special CPU 402, but the CPU 400 (or the special CPU 402) of the main control unit 200 performs this fraud non-detection. Receiving the signal input, it is determined that the anomaly caused by the fraud has been resolved.

  Then, when the abnormality due to the fraud is canceled (S901: YES), the CPU 400 (or the special CPU 402) sets the fraud flag assigned to its own predetermined address to off (S902). Note that if the abnormality due to the fraud is not canceled (S901: NO), the fraud flag is not set to OFF. Further, the fraudulent flag set to OFF here is referred to by the CPU 400 or the special CPU 402 in S511A of FIG.

  Next, the jackpot determination process S1000 executed by the CPU 400 of the main control unit 200 will be described based on the flowchart of FIG. As shown in FIG. 23, the CPU 400 (or the special CPU 402) of the main control unit 200 determines whether or not the cheating flag is on (S1001).

  If it is determined that the cheating flag is on (S1001: YES), the big hit flag is set off (S1002). Here, the big hit flag is a flag assigned to a predetermined address of the CPU 400. Then, when the result of the success / failure lottery determined by the random number value acquired by the random number lottery process is a big hit, the big hit flag is set to ON by the CPU 400. On the other hand, when the result of the success / failure lottery determined by the random number obtained by the random number lottery process is other than the big hit, the big hit flag is set off by the CPU 400. In S1002, when it is determined that the fraud flag is on (S1001: YES), the jackpot flag assigned to the predetermined address of the CPU 400 is set off (S1002). As a result, when an illegal act occurs, even if the big hit is won by the random number value obtained by the random number lottery process of the CPU 400, no big hit game is generated without inquiring about the contents of the determination result.

  When it is determined that the cheating flag is not on (is off) (S1001: NO), the CPU 400 determines whether or not the determination result (big hit determination result) is a big hit (S1003). The determination result is a determination result as to whether or not the game is a big hit, and is determined by the random number value acquired by the random number lottery process of the CPU 400. As a result, when it is determined that the determination result (big hit determination result) is not a big hit (S1003: NO), the big hit flag assigned to a predetermined address of the CPU 400 is set off because no big hit game is generated. (S1002).

  On the other hand, when it is determined that the winning / failing determination result (the jackpot determination result) is a jackpot (S1003: YES), the jackpot game is generated, so that the jackpot flag assigned to a predetermined address of the CPU 400 is set to ON ( S1004). Thereby, the big hit game is started at a predetermined timing.

  As described above, according to the first embodiment, when a fraudulent person performs a fraudulent act, the fraud detection unit 212 outputs a fraud detection signal to the CPU 400 and the special CPU 402 of the main control unit 200. As a result, the CPU 400 and the special CPU 402 determine that an illegal act has occurred. In this case, the special CPU 402 selects a special variation pattern different from the variation pattern (specified by the CPU 400) of the special symbol (the main symbol and the pseudo symbol) determined by the random value. As a result, the variation display of the special symbol based on the special variation pattern selected by the special CPU 402 is executed instead of the variation pattern designated by the CPU 400.

  Here, in the first embodiment, as the content of the special variation pattern, the variation of the special symbol is the longest time, and the result that the result of the lottery determination is not selected is selected (fixed). For this reason, when an illegal act occurs, the variation time becomes the longest variation time, and the variation display of the special symbol (the main symbol and the pseudo symbol) based on the extraordinary variation pattern is executed. Many variation patterns with long variation times have high reliability for big hits. As a result, the player who has committed fraud concentrates more on the game in anticipation of a variable display effect of a special symbol having a long variation time. For this reason, the tension of cheating is relatively weakened, resulting in a psychological state in which attention to surroundings (such as guards and hall personnel) is neglected. Note that even if a player who has committed fraud continues to produce a special symbol based on the special variation pattern, it will eventually be disengaged, so that the monetary damage caused by the fraudulent party will be lost. Does not occur.

  In this way, if a fraudulent act occurs, it is possible to concentrate on the game to the player who has committed the fraud and keep it on the spot, so that sufficient time to catch the fraudulent person can be gained. it can. In this sufficient time, by strengthening the security system and heading to the site of a game machine that is calmly cheating, it is possible to secure fraudsters safely and reliably. In addition, a player who commits cheating is obsessed with gaming, and therefore negates the evidence of cheating. As a result, it is possible to prevent the disappearance of evidence of fraud, and it is possible to prevent escape and escape due to misconduct of the fraudster.

  In the first embodiment, the change target of the special symbol by the special change pattern is described to be both the main symbol and the pseudo symbol, but at least the player (the fraudulent person) pays attention during the game. Only the “pseudo symbol” of the special symbol may be set as the variation target of the special variation pattern.

  Next, a second embodiment of the present invention will be described. In addition, the description overlapping with the first embodiment is omitted.

  The second embodiment relates to the control of the start timing of the special symbol variation display based on the special variation pattern changed in S511B of FIG. In the first embodiment, when a fraudulent act is detected, the next variation pattern is selected even if the special symbol is not changing or is changing. On the other hand, the second embodiment is an embodiment in which, when an illegal act is detected, the special symbol is already changing, and the changing pattern is changed to the special changing pattern.

  First, in the same manner as in the first embodiment, when a fraud occurs in S511B of FIG. 18, the special CPU changes the special symbol variation pattern determined by the CPU 400 of the main control unit 200 based on the random number value. It is changed to a fluctuation pattern. At this time, as the special variation pattern, the special CPU 402 selects a special variation pattern whose variation time is the longest time from the variation pattern group stored in the ROM 404 and from which the result of the lottery determination is off.

  At this time, a command signal (command data) designating a special symbol variation start timing (start timing) by a special variation pattern is output from the main control unit 200 to the sub-control unit 260 and the panel relay board 210 in particular. In the second embodiment, the contents of the command signal (command data) specifying the change start time (start timing) of the special symbol by the special change pattern are changed according to the current game progress.

  In the second embodiment, the variation start timing of the special symbol based on the special variation pattern is set as follows. That is, the variation start timing of the special symbol based on the special variation pattern is determined in correspondence with the current game progress status, not immediately after changing to the special variation pattern in S511B of FIG. If the current game progress is not matched, the special symbol game will be uncomfortable, and the player who is cheating will notice this discomfort and will attempt to hide or escape the evidence of cheating.

  Specifically, as shown in FIG. 24, the presently changing display of special symbols is divided into four sections A, B, C, and D. In other words, the display screen of the symbol display device 25 has three symbol display areas in which the pseudo symbol of the special symbol is variably displayed. The three symbol display areas are composed of a right symbol display area where the right symbol is displayed, a middle symbol display area where the middle symbol is displayed, and a left symbol display area where the left symbol is displayed. Section A is a section in which each pseudo symbol is variably displayed in the three symbol display regions of the right symbol display region, the middle symbol display region, and the left symbol display region. Section B is a section in which the pseudo symbol stops changing in the left symbol display area, and each pseudo symbol is variably displayed in the two symbol display areas of the right symbol display area and the middle symbol display area. Section C is a section in which the respective pseudo symbols stop changing in the left symbol display area and the right symbol display area, and the pseudo symbols change and display in the middle symbol display area. A section D is a section in which each of the pseudo symbols is variably stopped in the three symbol display areas of the right symbol display area, the middle symbol display area, and the left symbol display area.

  When an illegal act occurs (when an illegal act is detected) in section A, three symbols of a right symbol display area, a middle symbol display area, and a left symbol display area are displayed on the display screen of the symbol display device 25. In the display area, each pseudo symbol is variably displayed. At this time, since the variation pattern of the pseudo symbol that is variably displayed is the variation pattern specified by the CPU 400 of the main control unit 20 by the random number lottery process, the variation pattern is immediately changed to the special variation pattern changed in S511B of FIG. Switch to the fluctuating display with a special symbol based on the pseudo symbol. In particular, it is preferable to switch not only the pseudo-graphic variation display of the special symbol but also the variation display of the present symbol based on the special variation pattern. In this case, since three (all) pseudo symbols are changing in the three symbol display areas based on the variation pattern designated by the CPU 400, this is replaced with a pseudo symbol variation display based on the special variation pattern. However, there is no sense of incongruity. As a result, it is possible to prevent a player who has performed an illegal act from feeling uncomfortable with the fluctuating display of the pseudo symbols. Here, when the time of the section A is set to a short time, it becomes difficult in terms of time to replace the pseudo display with the variation display of the special variation pattern. For this reason, if the replacement can be performed within the minimum time on the basis of the minimum time of the section A, it is preferable to replace the display with a pseudo-pattern variation display with the special variation pattern.

  When an illegal act occurs (when an illegal act is detected) in section B, the pseudo symbol stops changing in the left symbol display area on the display screen of the symbol display device 25, and the right symbol display area In the two symbol display areas of the middle symbol display area, the respective pseudo symbols are variably displayed. In this case, it is preferable to change the display to the pseudo symbol variation display based on the special variation pattern immediately after the pseudo symbol stops varying in the left symbol display area. Specifically, the pseudo symbol in the left symbol display area has already stopped, but the pseudo symbol that is variably displayed in the two symbol display areas, the right symbol display area and the middle symbol display area, is based on a special variation pattern. Become. In this case, the variation time of the pseudo symbol that fluctuates in the right symbol display area and the middle symbol display area is the longest time, and is longer than the variation time of the pseudo symbol in the left symbol display area. However, since the variation start timing of the pseudo symbol that is variably displayed in the right symbol display area and the middle symbol display area does not deviate, it is possible to alleviate the uncomfortable feeling given to a player who has performed an illegal act. However, the left symbol stopped when it is not a special variation pattern and the left symbol stopped with a special variation pattern are the same (for example, if the symbol stopped when it is not a special variation pattern is “3”, it was stopped with a special variation pattern. If the symbols are not arranged in “3”), the player will feel uncomfortable.

  When an illegal act occurs (when an illegal act is detected) in section C, on the display screen of the symbol display device 25, each pseudo symbol stops changing in the left symbol display area and the right symbol display area. However, in the middle symbol display area, the pseudo symbol is variably displayed. In this case, it is preferable to change the display to a pseudo symbol variation display based on the special variation pattern immediately after the pseudo symbol stops varying in the right symbol display area. Specifically, the pseudo symbols in the left symbol display area and the right symbol display area have already been stopped, but the pseudo symbols that are variably displayed in the symbol display area in the middle symbol display area are based on a special variation pattern. In this case, the left symbol and the right symbol have a special variation pattern from the stopped state. If there are 9 types of symbols, at least 9 × 9 = 81 types of special variation patterns are not preferable. Therefore, in this case, it is preferable to end all the fluctuations and replace them with special fluctuation patterns at the next pseudo-pattern fluctuation start timing.

  In addition, when the fraud occurs (when the fraud is detected) in the section D, since the fluctuation of the pseudo symbols has already stopped in all the symbol display areas, this is different from the special variation pattern. It is difficult to change. In this case, it is preferable to replace it with a special variation pattern at the next pseudo symbol variation start timing.

  Next, a third embodiment of the present invention will be described. In addition, the description overlapping with the first embodiment is omitted.

  In the third embodiment, the content of the special variation pattern changed in S511B of FIG. 18 is the infinite time for the variation time of the special symbol (pseudo symbol) (the game machine 1 is turned off or the main control board 200a is reset) And the variation pattern is such that the result of the success / failure lottery is lost (in the first place, the determination of success / failure is invalid). In the third embodiment, it is only necessary to change the pseudo pattern variation pattern of the special symbol to the special variation pattern, and it is not always necessary to change the variation pattern of the special symbol main symbol to the special variation pattern. In other words, when only the special symbol pseudo-design is changed to the special variation pattern, the special symbol main symbol stops changing early, but only the special symbol pseudo-design continues to change long. However, it is also possible to change both the main symbol and the pseudo symbol of the special symbol to the variation display based on the special variation pattern.

  In the third embodiment, when an illegal act occurs while the special symbol is changing based on the change pattern designated by the CPU 400, the change pattern of the special symbol is changed to the special change pattern in S511B of FIG. However, the timing for starting the variation of the special symbol based on this special variation pattern becomes a problem. Here, in the third embodiment, since the variation time becomes infinite time, any player who uses the fraud will feel uncomfortable.

  Therefore, it is preferable to control the effect display control unit 280 so that the display screen (three symbol display areas) of the symbol display device 25 temporarily becomes white-out (a state in which the display screen is completely white). During this time, the fluctuation pattern designated by the CPU 400 is replaced with a special symbol fluctuation display based on the special change pattern. Thereafter, the display screen (three symbol display areas) of the symbol display device 25 is controlled so that the white-out (state in which the display screen is completely white) is eliminated. When returning to the normal display screen, the variation display of the special symbol (the main symbol and the pseudo symbol) based on the replaced special variation pattern is started. At this time, the player who has performed the fraudulent act is temporarily white-out (the display screen is completely white), which is surprising, but the game is continued to return to the normal game screen again. . Moreover, on the display screen (three symbol display areas) of the symbol display device 25, since the variation display of the special symbol based on the special variation pattern is executed, the variation time of the special symbol is infinite. A player who has made a mistake is unaware of the replaced facts. By controlling the display screen (three symbol display areas) of the symbol display device 25 in this manner, a sufficient time can be gained, and a player who has committed an illegal act can be secured safely and reliably.

  Note that the phenomenon that the display screen of the symbol display device 25 whites out may be abruptly felt, but is often seen when the game is developed so-called super reach after the game state becomes so-called reach. It is a phenomenon. For this reason, in the normal gaming machine 1, there is a possibility that the display screen of the symbol display device 25 is whitened out, so that a player who has cheated does not feel so uncomfortable. Also, since the fluctuation time lasts indefinitely, a player who cheats may eventually feel uncomfortable. However, the hall officials are not called. This is because they do cheating and don't want to reveal the cheating to the people involved in the hall themselves.
