Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a technique for detecting an illegal act by an unauthorized player.

  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called big hit, in which more prize balls can be obtained than a normal game when the combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific aspect. It is known as a thing (for example, refer patent document 1). The variable display of symbols in the display area is not limited to simply displaying multiple symbols in a variable manner, but the time required for the variable display to be a big hit if one more symbols are aligned, such as the so-called reach screen. For example, an effect is made to increase the player's expectation, such as making it longer. In addition, a character image, background image, etc. can be used to create a story with a variation display of the symbol, probability variation to increase the efficiency of transition to special games, shortening the variation time, and ease of entering the starting prize opening. The player's expectation is also enhanced by the control to shift to the easy entry state.

  By the way, there is known an unauthorized player called a “Goto” who tries to obtain a prize ball from a gaming machine using various illegal means. Every time a new method comes to light, game machine manufacturers take measures, but new methods and their damage are constantly being discovered. In recent years, a technique that has become known in the past is to attach an inconspicuous thread member such as a fishing line to a game ball and enter the winning opening, and repeatedly pull and relax the thread member to enter the winning opening many times. There are fraudulent acts that cause the sensor to react. Although techniques for accurately counting the number of payouts for prize balls are known (see, for example, Patent Document 2), an illegal player is charged with fraudulent acts so that prize balls caused by fraudulent acts are confused with legitimate prize balls. If the timing was adjusted, gaming machines and hall computers could not distinguish and count them, and could not prevent the injustice.

  In addition, some unauthorized players can acquire the gaming machine itself in some way before playing at the amusement store, fully analyze the operation of the gaming machine in an environment where the eyes of surveillance are not reachable, There are even those who abuse the analysis results at amusement stores. For this reason, it is necessary to take measures to prevent the result of analysis outside the game store from being used as it is in the game store.

  The present invention has been made in view of such problems, and one of its purposes is to detect fraudulent acts by unauthorized players with high accuracy and to prevent fraudulent acts. Another object is to prevent fraud by making it difficult to guess the detection standard of fraudulent acts by an unauthorized player.

  In order to solve the above-described problems, a bullet ball game machine according to an aspect of the present invention is provided with a game board on which a game area is formed, and a predetermined position in the game area. And a winning determination means for determining whether or not to shift to a special game that is more advantageous to the player than a normal game. Winning lottery means, a large winning opening that is provided at a predetermined position different from the winning opening in the game area and is open in special games and allows game balls to enter, and a big win when the result of the winning lottery is a big hit Special game control means for executing a special game by opening and closing the mouth, a entrance rate calculation means for calculating a rate of entering a winning entrance in a predetermined period, a rate of entering a special entrance game and a special rate Ratio to the winning rate in winning games There is judged that error when exceeds a predetermined judgment value, as well as informing the error after the elapse of the grace period from the determination, and an error determination means for setting the time value of the variable as the grace period.

  Here, as the “entrance rate”, a value of the number of entrances per unit time may be used, or a ratio of the number of entrances to the number of launches per unit time may be used. In addition, in order to calculate the “entry rate”, the number of entrances to the winning entrance may be actually counted and used to calculate the entrance rate, or the winning ball triggered by entering the winning entrance The number of payouts may be counted to estimate the number of balls entered, and the estimated value may be used for calculating the entrance rate. The “winning entrance” may be a start winning entrance where the entrance of a game ball is a lottery or may be provided at a predetermined position different from the start winning entrance and the big winning entrance, It may be a general winning opening that triggers the payout. In the case of a starting prize opening, a normally open type entrance, that is, an entrance type that is not normally closed such as an open / close type, or an open type entrance that allows a part of the entrance to remain open even when closed. It may be a mouth. As the “predetermined period”, a lower limit value of the time for counting the number of entering balls may be set in order to reduce the statistical error of the calculated entering rate. As the “predetermined judgment value”, for example, a value that exceeds the range that can occur in a normal game procedure may be set based on an experimental value or a design value. A value such as 3 times may be set as a non-existing value. The “notify error” may notify the error using display on a predetermined display device, sound output, or lamp lighting, or may be notified by outputting an error to a terminal on the amusement store side. The notification may be made by forcibly stopping the launch of the game ball.

  According to this aspect, it is possible to detect when a number of balls that cannot be normally generated at a winning opening that should be substantially constant regardless of the gaming state, can be detected. In particular, during a special game where the number of prize balls paid out increases rapidly, the prize ball is illegally entered only during the special game in order to generate a prize ball triggered by the entry to the prize opening so as to be inserted into the prize ball. This can be detected when a fraudulent act is caused. For example, a fraudulent act such as attaching an inconspicuous thread-like member such as a fishing line to a game ball and entering the winning opening, and repeatedly reacting to the winning sensor at the winning opening by repeatedly pulling and relaxing the thread-like member. Conceivable. Conventionally, even if such an action is performed during a normal game, there is a case where it can be determined as an error by a function for detecting a sudden increase in prize balls other than the special game. However, with such functions, it is not possible to discriminate from a legitimate increase in the number of winning balls, even if the number of winning balls rapidly increases, because illegal acts that are performed only during a special game are in special games. It was. In this mode, it is possible to effectively detect an illegal act during a special game and determine an error. Further, according to this aspect, it is possible to determine that this is a fraudulent entry when an unacceptable amount of entry occurs at the winning opening, and the judgment criteria can be easily estimated from the outside. You can make it impossible. In other words, even if the fraudulent obtains the ball game machine and analyzes what numerical value is used to determine the error, the numerical value does not necessarily match the error notification timing, and the actual error determination Since a variable time lag occurs from notification to notification, analysis of the determination value from the outside becomes difficult. Accordingly, it is possible to reduce the willingness to analyze by an unauthorized person and to expect suppression or prevention of fraud.

  The error determination means may set a variable value as the determination value. “Set a variable value as a judgment value” may be a method of automatically or manually setting a variable value as a judgment value, or a method of setting a variable value for each lot of gaming machines as a judgment value before product shipment. Good. In other words, even if a fraudster obtains a gaming machine of the same model and analyzes the judgment value, a variable value may be set so that a different judgment value is set when actually playing a game in a gaming store. That's fine.

  According to this aspect, it is possible to determine that this is a fraudulent entry when an unacceptable amount of entry has occurred at the winning opening, and the determination criterion cannot be easily estimated from the outside. Can be. In other words, even if the fraudulent obtains the ball game machine and analyzes what numerical value is used to determine the error, the numerical value is set to be a variable value. Even if the game is actually played at the game store based on the result, it does not operate as analyzed. Or, even if theoretical analysis is possible if a considerable amount of time is spent, but if effective analysis is impossible unless it takes such a long time compared to other gaming machines, it is fraudulent. It is possible to reduce fraudulent analysis motivation by, and to expect fraud suppression or prevention.

  The error determination means may set a random value included in a predetermined value range as a determination value every time a predetermined setting timing is reached.

  Here, the “predetermined value range” is an adjustment state of the game nails around the winning hole so that it does not exceed the judgment value accidentally when a normal player is playing without any fraudulent purpose. Even if it is sweet, it may be designed by obtaining a range of judgment values that cannot normally be exceeded by experiments in the design stage. The “predetermined setting timing” can be designed at an arbitrary timing or setting interval. For example, the determination value may be updated to a new value every time the counting period elapses. According to this aspect, it is possible to prevent an error from being easily guessed from the outside by making an error determination criterion random, and even if an unauthorized person tries to obtain and analyze the ball game machine, it is easily analyzed. It is not possible or at least a considerable amount of time is required for analysis, and fraud suppression or prevention can be expected.

  The error determination means may set, as the determination value, a random value dispersed so that the setting frequency for a value close to the boundary value in the predetermined value range is lower than the setting frequency for a value far from the boundary value.

  Here, the “boundary value of the predetermined value range” may be the lower limit value of the value range, the upper limit value, or both the lower limit value and the upper limit value. As for the dispersion of the judgment value, for example, a dispersion value so as to draw a normal distribution curve having a peak near a middle value between the lower boundary value and the upper boundary value may be set as the judgment value. In this aspect, the frequency at which the value close to the boundary value of the value range is set as the determination value is lower than the frequency at which the value far from the boundary value is set as the determination value. It can be made difficult to guess from the outside easily. In other words, even if an unauthorized person tries to obtain and analyze the ball game machine, a boundary value with a low setting frequency cannot be easily analyzed, or at least a considerable amount of time is required for analysis. I can expect.

  You may further provide the setting switch for instruct | indicating the setting of a determination value by operation of an operator. The error determination unit may hold a plurality of types of candidate values as determination value candidates, and set one of the plurality of types of candidate values as a determination value in accordance with an operation of a setting switch by the operator.

  Here, the “candidate value” may be a specific numerical value or a numerical value range. The “setting switch” may be provided at a position where only the game shop clerk can operate, such as a position where the player cannot operate, for example, the back side of the ball game machine or the back side of the game board. In this aspect, the game shop clerk can fine-tune the severity of the judgment criteria according to the degree of nail adjustment near the prize opening for each gaming machine, and set a more appropriate judgment value to make an appropriate error judgment Can do.

  A main control device that mainly controls a basic operation of a game including a lottery process, and a sub-control device that mainly controls an effect operation of a game including a display process for indicating a result of the lottery process. . The entrance determination means is provided in the main control device, the entrance rate calculation means and the error determination means are provided in the sub-control device, and the entrance rate calculation means is from the entrance determination means provided in the main control device. You may calculate the winning rate to a winning opening by receiving and counting the information of a winning ball.

  According to this aspect, since the calculation of the winning rate at the winning opening and the determination of the error can be processed on the so-called sub board side, the so-called main board side transmits a signal indicating the entering of the winning hole to the sub board. Just do it. In the main board, for example, the ROM capacity for storing control programs and data is limited to 3 kilobytes, the storage capacity of the RAM is limited to 1 kilobyte, and the use area is limited to 512 bytes. Therefore, the designer wants to increase the storage capacity by reducing the data stored in the ROM or RAM even by 1 byte. Therefore, there is a great merit in design that the program for calculating the number of balls entered into the prize opening and the error judgment processing program are installed on the sub board, and it is not necessary to install it on the main board. Can be used effectively for different programs.

  The winning prize opening is a start prize opening where a game ball entry is a lottery opportunity, and a general prize where a game ball entry is an opportunity for paying out a prize ball at a predetermined position different from the start prize opening and the big prize opening And a mouth. The winning / losing lottery means performing the winning / losing lottery upon entering the starting winning opening, the winning rate calculating means calculates the winning rate to the general winning opening, and the error determining means is the general winning in the normal game. You may alert | report an error, when the ratio of the entrance rate to a mouth and the entrance rate to the general winning opening in a special game exceeds a judgment value. In this aspect, an abnormal state in which the balls are concentrated only during the special game is detected with respect to the general winning port which is normally a winning port that does not affect the progress of the game. Thereby, fraudulent acts can be detected with high accuracy.

  The winning rate calculation means calculates the winning rate at the winning hole in the normal game for a predetermined period after the power is turned on, and then calculates the winning rate at the winning hole at the special game every time the special game is executed. May be. Here, the “predetermined period after the power is turned on” is a period after the player first fires the game ball in the normal game after the power is turned on, or a period after the game ball first enters the winning opening. Alternatively, it may be a period from power-on to the first special game. In this mode, the winning rate calculation means calculates the winning rate at the winning opening in the normal game once, and then only calculates the winning rate at the winning port in the special game. , Can detect fraud efficiently. In addition, every time the power is turned on, the rate of entry to the winning hole in normal games is calculated, so even if the direction of the game nail is changed every day, the individual difference in the rate of entry that occurs every table or every day is used as a criterion. It can be reflected, and fraud can be detected with high accuracy.

  When the special game is executed, the rate of winning rate calculation means that if the rate of winning in the normal game is not yet calculated, the rate of entering the winning hole in the normal game after the special game is executed. The error determination means obtains, from the winning rate calculation means, the winning rate at the winning hole in the normal game and the winning rate at the winning hole in the special game, and enters the winning hole in the special game. If the winning rate in the winning game in the normal game has not been acquired at the time when the winning rate is acquired, the winning rate in the winning game in the normal game after the execution of the special game may be acquired. In this aspect, for example, even if a special game occurs shortly after the power is turned on, and even before that, an effective value as a winning rate in a winning game in a normal game has not been calculated, the special game Later, an effective value can be calculated again to determine the ratio of the entrance rate. Even in such a case, the individual difference in the entrance rate can be reliably reflected in the determination criterion, and the fraud can be detected with high accuracy.

  It should be noted that any combination of the above-described constituent elements, and the constituent elements and expressions of the present invention are mutually replaced between a method, an apparatus, a system, a computer program, a recording medium storing the computer program, a data structure, and the like. This is effective as an embodiment of the present invention.

(First embodiment)
In this embodiment, an illegal act by an unauthorized player is caused when the ratio of the rate of entering a general winning opening in a normal game and the rate of entering a general winning opening in a special game exceeds a predetermined reference ratio. Judge that there was. As a fraudulent act, attach an inconspicuous thread-like member such as fishing line to the game ball, enter the general winning opening, and repeat the pulling and relaxation of the thread-like member to react to the general winning opening's entrance sensor many times. Action can be considered. If such an act is executed during a normal game, it may be detected by a function of a gaming machine or a hall computer that detects a sudden increase in the number of prize balls other than a special game. It is conceivable to avoid the execution of fraudulent acts that misuse thread-like members. On the other hand, in the special game, since the number of prize ball payouts is suddenly increased from the beginning, even if an illegal act that misuses the filamentous member is executed, it cannot be detected by the conventional function. For example, in a special game that actually has only 8R unit games, even if there are balls corresponding to 15R unit games, it is not possible to determine whether the game has been played due to fraud. Therefore, in the present embodiment, the rate of entering into the general winning opening is calculated separately during the normal game and the special game, and an illegal winning is detected by comparing these.

  FIG. 1 shows a basic structure on the front side of a pachinko gaming machine. Hereinafter, a so-called first type pachinko gaming machine, which is conventionally known as a bullet ball gaming machine, will be described as an example. The pachinko gaming machine 10 is mainly composed of a gaming machine frame and a gaming board. The gaming machine frame of the pachinko gaming machine 10 includes an outer frame 11, a front frame 12, a transparent plate 13, a door 14, an upper ball dish 15, a lower ball dish 16, and a launch handle 17. The outer frame 11 has an opening and is a frame for fixing the pachinko gaming machine 10 to a position where it should be installed. The front frame 12 is a frame body that aligns with the opening portion of the outer frame 11, and is attached to the outer frame 11 so as to be opened and closed by a hinge mechanism (not shown). The front frame 12 includes a mechanism for launching a game ball, a mechanism for detachably storing a game board, a mechanism for guiding or collecting the game ball, and the like.

  The transparent plate 13 is made of glass or the like and is supported by the door 14. The door 14 is attached to the front frame 12 so as to be openable and closable by a hinge mechanism (not shown). The upper ball tray 15 has a mechanism for storing game balls, sending the game balls to the launch rail, extracting the game balls to the lower ball tray 16, and the like. The lower ball tray 16 has a mechanism for storing and extracting game balls. A speaker 18 is provided between the upper ball tray 15 and the lower ball tray 16, and a sound effect corresponding to the gaming state or the like is output by means for controlling an effect described later.

  The game board 50 has an out port 58, a special symbol display device 61, an effect display device 60, and a start winning port (hereinafter referred to as “start port”) 62 on a game area 52 defined by the outer rail 54 and the inner rail 56. , A center ornament 64, a grand prize opening 66, an operation opening 68, and a general prize opening 72. Furthermore, in the game area 52, a plurality of mechanisms such as a game nail and a windmill (not shown) are installed.

  The starting port 62 is a starting port that triggers a game ball to enter a prize ball payout and a lottery, and a start winning detection device 74 for detecting the entering of a game ball, and the starting port 62 A normal electric accessory solenoid 76 is provided for expanding the expansion mechanism 63 (so-called electric tulip) provided in the apparatus. The expansion mechanism 63 is composed of two blade members provided at the upper part of the opening of the starting port 62, and the game ball falling from just above the starting port 62 has an opening width capable of entering even when closed. On the other hand, when the expansion mechanism 63 is expanded and opened, the opening width of the start port 62 is widened, and not only the start port 62 but also a game ball falling in the vicinity thereof can be guided to the start port 62 and can enter. Ease is improved. This lottery determination is a lottery for determining whether or not to shift to a special game that is more advantageous to the player than a normal game, and is executed every time there is a ball entering the start port 62. The start winning detection device 74 is a sensor that detects the entry of a game ball into the start port 62, and generates start win information indicating the winning at the time of entering. For example, the prescribed number of prize balls for entering the starting port 62 is three.

  The general winning opening 72 is a winning opening different from the start opening 62 and the large winning opening 66 described later, and includes a general winning detecting device 73 for detecting the entering of a game ball. The general winning detection device 73 is a sensor that detects the entry of a game ball into the general winning opening 72, and generates general winning information indicating the winning at the time of winning. The general winning opening 72 is a trigger for paying out a winning ball, like the starting opening 62 and the big winning opening 66, but unlike the starting opening 62 and the large winning opening 66, the winning is used for the progress of the game. It has no effect and is not an opportunity other than a prize ball. The prescribed number of winning balls for entering the general winning opening 72 is, for example, ten.

  The special winning opening 66 includes a winning detection device 78 for detecting the entry of a game ball and a special winning opening solenoid 80 for opening the special winning opening 66. The winning detection device 78 is a sensor that detects the entry of a game ball into the big winning opening 66, and generates big winning opening winning information indicating the winning at the time of winning. The big winning opening 66 is a horizontal rectangular winning opening that is opened as a “big hit” in a special game that starts when the special symbol 192 stops in a predetermined manner. The big winning opening 66 is provided at a position above the out opening 58, for example. The number of the big winning openings 66 is not limited to a single arrangement, and a plurality of large winning openings 66 may be installed and used depending on the gaming state or the like. The winning detection device 78 of the big winning opening 66 includes a sensor that detects the passage of a game ball. The prescribed number of winning balls for entering the big winning opening 66 is, for example, fifteen.

  As described above, the general prize opening 72 has the largest number of prescribed prize balls next to the big prize opening 66, and the prescribed prize ball number of the general prize opening 72 is larger than the prescribed prize ball number of the start opening 62. . Therefore, in the case of a gaming machine provided with a function for detecting illegal entry to the big prize opening 66, an illegal player aims at the general prize opening 72 having the next largest prize ball 66 after the big prize opening 66. Easy to think about. In the present embodiment, as will be described later, an illegally entered ball aimed at the general winning opening 72 is detected.

  The special symbol display device 61 provided on the left side of the game area 52 and the effect display device 60 provided in the approximate center of the game area 52 have a variation of the special symbol 192 on each screen and a decoration linked to the special symbol 192. Changes in the effect image including the pattern 190 are displayed. Hereinafter, such display is referred to as “design variation” or “variation display”.

  The special symbol display device 61 is a display device composed of, for example, 7 segment LEDs. The special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball falls into the start port 62. When the symbol mode when the special symbol 192 is stopped is the symbol that is determined in advance, the timing at which the symbol is displayed is the big hit occurrence timing. The stop symbol is a symbol to be displayed at the end of symbol variation. The special symbol 192 in the present embodiment is represented by numbers, characters, symbols such as “0” to “9” that are hit symbol patterns, or a symbol “−” that is an off symbol pattern. These numbers or symbols are replaced one after another at a high speed and displayed on the special symbol display device 61, whereby the symbol variation display of the special symbol 192 is realized. Note that the special symbol 192 is not limited to the above numbers or symbols, and may be letters such as English letters, or may be a generally meaningless symbol formed by a combination of segments constituting a 7-segment LED. May be. Further, the 7-segment LED may be composed of 8 segments including 7 segments forming “eight-letter shape” and 1 segment representing “dot”. In this case, a numerical value for 8 bits can be expressed by combining 8 segments. Further, the special symbol display device 61 may be an LED dot array that is not a 7-segment LED, and a plurality of types of special symbols 192 may be expressed by combinations of lighting patterns and lighting colors.

  The effect display device 60 is a display device configured by a liquid crystal display that displays the decorative symbol 190 in a variable manner in conjunction with the variable symbol display of the special symbol 192. The decorative symbol 190 is a symbol for visually rendering the lottery result display indicated by the special symbol 192. The effect display device 60 displays, for example, a moving image that fluctuates a plurality of rows of symbols simulating a game of a slot machine as a decorative symbol 190 in the central area of the screen. In this embodiment, symbols composed of numbers “0” to “9” are displayed and varied in three columns, and hit or miss is indicated by three symbol combinations that are finally stopped and displayed. Each of the plurality of symbols constituting the decorative symbol 190 is composed of numbers, characters, or symbols that are decorated with colors or patterns, but these symbols, characters, or symbols are common to all symbols. You may comprise in the form which adds a different pattern for every and integrates them. This pattern is a pattern on which a motif related to the theme of decoration or production set for the model of the pachinko gaming machine 10 is drawn, and for example, a pattern on which a character of a person or an animal is drawn may be used. The decorative pattern 190 is switched according to the development of the effect between the case where the design that includes the design is variably displayed and the case where the design is separated and only the numbers, characters, and symbols are variably displayed. It may be a configuration. On the background of the variation display of the decoration symbol 190, a moving image having a staging effect related to the theme of decoration or production set for the model of the pachinko gaming machine 10 is displayed in conjunction with the symbol variation.

  The effect display device 60 is configured by a high-definition dot matrix type display device such as a liquid crystal display in this embodiment, but may be configured by a mechanical display unit such as a drum rotation type or a display unit such as an LED matrix type. Good. Since the special symbol 192 does not necessarily have a role of production, in this embodiment, the special symbol display device 61 on the lower left side of the production display device 60 is displayed in an inconspicuous size. However, in the case of adopting a technique in which the special symbol itself has an effect role to express without using the decorative symbol, the special symbol may be displayed on the liquid crystal display instead of the 7-segment LED.

  The operation port 68 is provided at the left side position of the game board 50. The operation port 68 includes a passage detection device 69. The passage detection device 69 is a sensor that detects the passage of the game ball to the operation port 68, and generates passage information indicating the passage at the time of passage. The passage of the game ball to the operation port 68 triggers an open lottery that determines whether or not the expansion mechanism 63 is expanded. When the game ball passes through the operation port 68, a normal symbol, which is a symbol indicating the result of the open lottery, is variably displayed on the normal symbol display device 59. Therefore, the open lottery is also called “ordinary symbol lottery”. The normal symbol display device 59 in this embodiment is composed of two lamps for convenience, and the display state of the normal symbols is expressed by which of these lamps is lit. For example, when the first lamp is turned off and the second lamp is hit, the normal symbol fluctuation display is expressed by alternately turning on and off, and finally one of the lights is turned on. A stop symbol of a normal symbol is expressed by being stopped in the state. The normal symbol display device 59 is provided on the lower right side of the effect display device 60. After a predetermined time has elapsed since the start of the change, the normal symbol change display stops. At this time, in the normal state, the normal symbol stops at the winning symbol with a low probability of, for example, about 1/256, and in the easy entry state described later, the normal symbol is in the winning symbol with a high probability of, for example, about 250/256. Stop. When the normal symbol stops at the winning symbol, the expansion mechanism 63 is expanded for a predetermined time. The opening time of the spreading mechanism 63 is, for example, 0.1 seconds in the normal state, and 6 seconds in the easy entry state.

  A center ornament 64 is provided around the effect display device 60. The center decoration 64 has functions such as a flow path of the game ball, protection of the effect display device 60, and decoration. The special symbol hold display device 20 is provided at the lower left portion of the game area 52, and the normal symbol hold display device 22 is provided below the normal symbol display device 59 at the lower right portion of the game area 52, which is the symmetrical position. ing.

  The special symbol hold display device 20 is composed of four lamps, and displays the number of lottery holds depending on the number of lights. The number of lottery holds is the number of lottery results won to the start port 62 during symbol variation or special game, and indicates the number of winning balls for which symbol variation has not yet been executed. When the number of lottery holds is three, the symbol variation time in the case of a loss is shortened from the normal time in order to increase game efficiency (hereinafter also referred to as “shortening variation”). Similarly, when the number of pending lottery holds is 4, in order to further increase the game efficiency, the symbol variation time in the case of losing is further shortened than in the case of the above 3 (hereinafter also referred to as “super shortened variation”). ).

  The normal symbol hold display device 22 is also composed of four lamps, and displays the number of normal symbol fluctuation hold depending on the number of lights. The number of normal symbol fluctuations held is the number of game balls that have passed through the operation port 68 during the fluctuation of the normal symbol, and indicates the number of normal symbol lotteries for which the fluctuation of the normal symbol has not yet been executed.

  Game effect lamps 90 are respectively provided above and below the effect display device 60. The operation button 82 is an operation input unit that is operated by the player to input a predetermined instruction to the gaming machine, and changes are made to the contents of the effect according to the contents of the operation input. The operation button 82 is provided on the outer wall surface near the upper ball tray 15. Although the operation button 82 in this embodiment is composed of one button, it may be composed of a plurality of buttons and direction instruction buttons such as a cross key. The movable accessory 140 is a movable object whose operation is controlled in conjunction with the effect, and plays an effect role by the operation. For example, the movable accessory 140 operates in response to an operation input via the operation button 82 by the player.

  An outline of a game method and a control flow performed in the above configuration will be described. When the player turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 56 and the outer rail 54 with a strength corresponding to the turning angle, thereby playing the game area. To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball is dropped into each of the general winning opening 72, the start opening 62, and the big winning opening 66, a predetermined number of winning balls corresponding to the type of the winning opening is the upper ball plate 15 or the lower ball plate 16. To be paid out. A game ball dropped into each winning hole such as the general winning hole 72 is processed as a safe ball, and a game ball dropped into the out hole 58 is processed as an out ball.

  When the game ball falls into the start port 62, the special symbol 192 and the decorative symbol 190 are variably displayed on the special symbol display device 61 and the effect display device 60. The variation display of the special symbol 192 and the decorative symbol 190 is stopped after the lapse of the variation display time determined prior to the display. The special symbol 192 is variably displayed in accordance with a variation pattern in which a variation mode from the variation start to the stop is determined. The decorative symbol 190 is variably displayed according to a variation effect pattern in which a variation mode from the start to the end of the variation is determined. A plurality of types of variation patterns and variation production patterns are prepared, and each has various variation times. While the special symbol 192 is variably displayed according to the variation pattern, the decorative symbol 190 is variably displayed according to the variation effect pattern having the same variation time. In the variation pattern, a variation display time is determined for each pattern as an end condition of the symbol variation, and the variation of the special symbol 192 and the decorative symbol 190 is stopped when the variation display time elapses.

  As a variation display of the decorative symbol 190, first, as the variation starts, the symbols are varied in all three columns like the reel rotation of the slot machine, and when it approaches the variation end timing, it is stopped one by one as a final stop mode. The symbol combination is displayed. When the special symbol 192 and the decorative symbol 190 at the time of the stop are in a stop mode indicating a big hit, the game shifts to a special game that is more advantageous to the player than the normal game, and the opening / closing operation of the big prize opening 66 is started. The The stop mode of the decorative symbol 190 indicating a big hit is, for example, a combination mode in which the types of three symbols match.

  The variation effect pattern includes a normal loss effect pattern, a reach failure effect pattern, and a reach jackpot effect pattern. The normal off effect pattern is an effect pattern for displaying a normal off symbol combination. The reach out effect pattern is an effect pattern for displaying an out symbol combination through a reach state, which is a big win if one more symbols are arranged. The reach jackpot effect pattern is an effect pattern when displaying a jackpot symbol combination through the reach state. In particular, the patterns when reaching the reach state include patterns with various long and short fluctuation times. Reach patterns with relatively short fluctuation times are called “normal reach”, and reach patterns with long fluctuation times are called “super reach”. ".

  The special game is started by displaying an effect screen called start demonstration time. After the start demonstration time is displayed on the screen, the grand prize winning opening 66 is opened, and after the opening lasts for about 30 seconds, or after nine or more game balls have dropped in, it is temporarily closed. From such opening to closing of the big prize opening 66 is basically called a unit game, but it may be repeated a plurality of short-time opening during one unit game. After the opening / closing of the special prize opening 66 or the unit game is repeated a predetermined number of times, for example, 15 times, the special game is ended by displaying an effect screen called an end demo time. On the other hand, when the winning lottery corresponds to a result called “small hit”, the small hit game is executed. The small hit is a result included as a result of the lottery. The small hit game is a unit game executed in a manner similar to some types of special games. However, the unit game executed as a small hit game is only one time, which is different from a special game in which a plurality of unit games are executed.

  In the normal game after the end of the special game, the fluctuation time of the special symbol 192 and the decorative symbol 190, which are one of the specific games, is started (hereinafter referred to as “time reduction” as appropriate). The time shortening of the special symbol 192 and the decorative symbol 190 is a state in which the variation time of the special symbol 192 and the decorative symbol 190 is shortened from the normal state. The variation time of the special symbol 192 and the decoration symbol 190 is returned to the original variation time after a predetermined variation number, for example, 100 variation display, but if the big hit occurs before the variation number is reached, the time is shortened. Also ends. Due to the shortening of time, the variation time of the special symbol 192 and the decorative symbol 190 is shortened, so that it is possible to shorten the time until the big hit occurs compared to the normal state where the symbol variation is performed with the normal variation time. Therefore, it is possible to relatively increase the jackpot acquisition ease.

  During the time shortening of the special symbol 192 and the decorative symbol 190, the easy entry state which is one of the specific games is performed. The easy entry state is a state in which the ease of entering the starting port 62 is enhanced by executing the short time of the normal symbol, the probability variation of the open lottery, and the open extension of the expansion mechanism 63. The normal symbol time reduction is a state in which the variation time of the normal symbol is shortened from the normal state. The probability variation of the open lottery is a state in which the winning probability of the open lottery is higher than the normal state. The opening extension of the spreading mechanism 63 is a state in which the opening time of the spreading mechanism 63 is longer than the normal state. As described above, in the easy entry state, the possibility that the number of fluctuations of the normal symbol per certain time increases as compared to the normal state increases, and the ease of entering the start opening 62 also increases. There is a high possibility that the number of entering will increase. Therefore, due to the shortened time of the special symbol 192 and the decorative symbol 190 and the easy entry state, the chance to obtain a winning ball by entering the starting port 62 increases during that period, and as a result, the player can play the game with little decrease in possession. It is possible to continue.

  Note that the easy entry state in the present embodiment increases the ease of entering the starting port 62 by using three functions such as a short time for a normal symbol, a probability variation of an open lottery, and an open / extended extension of the expansion mechanism 63. However, as a modification, it is good also as a structure which improves the entrance ease to the starting port 62 using one or two functions among these three functions. Thus, even if only a part of the three functions is used, it is possible to improve the ease of entering the starting port 62. Moreover, it is good also as a structure which switches according to a gaming state at least any one of three functions by the period to implement and the period which does not implement.

  When a special game occurs and the winning stop pattern at that time is in a specific mode, the probability variation game of the winning lottery (hereinafter referred to as “probability change” as appropriate) that is one of the specific games after the end of the special game ) Is further started. During the chance change of the winning / failing lottery, the winning / failing lottery with a higher probability of winning than the normal probability state is performed, and a new special game can be generated relatively early. The probability change of the success / failure lottery is continued until the next big hit occurs, but as a modification, it may be configured to end when a predetermined limited number of symbol changes are made. In this embodiment, the special symbol 192 and the decorative symbol 190 are started at the same time as when the probability change is started, and the easy entry state is also started. May be executed.

  FIG. 2 shows a basic structure on the back side of the pachinko gaming machine. The power switch 40 is a switch for turning on / off the power of the pachinko gaming machine 10. The main board 102 controls the overall operation of the pachinko gaming machine 10 and processes all game operations such as a lottery when a winning is made to the start port 62. The sub board 104 includes the liquid crystal unit 42 and controls display contents on the effect display device 60, operations of the plurality of movable objects 140, and lighting of the game effect lamp 90, and in particular, display contents according to the lottery result by the main board 102. And the lighting of the movable accessory 140 and the game effect lamp 90 is activated along with the progress of the production. The main board 102 and the sub board 104 constitute a game control device 100. The back setting mechanism 39 includes a prize ball tank 44, a flow path for prize balls, a payout unit 43 for delivering prize balls. The payout unit 43 pays out the game balls supplied from the prize ball tank 44 to the upper ball tray 15 with a prescribed number of prize balls according to the prizes received at the respective prize openings. The payout control board 45 controls the payout operation by the payout unit 43. The launching device 46 launches the stored balls in the upper ball tray 15 to the game area 52 one by one. The launch control board 47 controls the launch operation of the launch device 46. The power supply unit 48 supplies power to each part of the pachinko gaming machine 10.

  FIG. 3 shows functional blocks of the pachinko gaming machine 10 in this embodiment. In the pachinko gaming machine 10, the game control device 100 includes a start port 62, a big winning port 66, a general winning port 72, an operating port 68, a special symbol display device 61, an effect display device 60, a normal symbol display device 59, and operation buttons 82. The speaker 18, the game effect lamp 90, and the movable accessory 140 are electrically connected to each other, and can transmit and receive various control signals. The game control apparatus 100 controls not only the basic operation of the game but also the staging operations such as the symbol variation display, the movable accessory 140, and the electric decoration. The game control device 100 is configured in such a manner that functions are shared between a main board 102 that controls the overall operation of the pachinko gaming machine 10 including basic operations of the game, and a sub board 104 that controls design effects and the like. The game control device 100 is configured by hardware including elements such as a ROM and a RAM for storing data and programs, and a CPU used for arithmetic processing.

  In the present embodiment, the main board 102 is a ball determination unit 110, a winning / failing lottery unit 112, a symbol determination unit 114, a variation pattern determination unit 115, a hold control unit 116, a main display control unit 118, a special game control unit 120, a specific game. An execution unit 122, an opening / closing control unit 124, a ball entering rate calculation unit 126, and an error determination unit 128 are provided. The sub-board 104 in the present embodiment includes a pattern storage unit 130, a design mode determination unit 131, an effect determination unit 132, an effect display control unit 134, and an accessory control unit 136. Each functional block included in the main board 102 may be configured such that any one of the functional blocks is mounted on the sub board 104 instead of the main board 102. Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.

  However, since data transmission / reception between the main board 102 and the sub board 104 is unidirectional from the main board 102 to the sub board 104, each operation is performed so that the entire operation is realized by such data transmission / reception in one direction. The configuration is arranged on the main board 102 and the sub board 104. In this way, since the unidirectionality of data transmission from the main board 102 to the sub board 104 is maintained, data cannot be transmitted from the configuration included in the sub board 104 to the configuration included in the main board 102. It is not possible to request data transmission. Therefore, the information generated on the main board 102 cannot be referred to from the sub board 104 unless the main board 102 unilaterally transmits the information to the sub board 104.

  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68. The winning determination means 110 sends start winning information, large winning opening winning information, and general winning information to the winning rate calculation means 126 and information on the prescribed number of winning balls according to each winning information. Send to.

  The success / failure lottery means 112 obtains, as a success / failure lottery value, a random number value for determining whether or not to shift to a special game that is more advantageous to the player than the normal game when the starting hole 62 is entered. To do. For example, the success / failure lottery value is acquired from a value range from “0” to “65535”. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The value acquired as the success / failure lottery value by the success / failure lottery means 112 is temporarily held by the hold control means 116. However, the lottery value is held within a range not exceeding the predetermined holding upper limit number.

  The success / failure lottery means 112 holds a plurality of success / failure tables to be referred to in the success / failure determination. In the plurality of success / failure tables, determination results of big hits, small wins, and misses are associated with the success / failure lottery values, and the success / failure probabilities are determined according to the associated jackpot range settings. The success / failure lottery means 112 refers to the success / failure table based on the normal probability at the normal time, and refers to the success / failure table whose probability of winning is higher than the normal probability when the probability changes. The success / failure lottery means 112 refers to any of the plurality of success / failure tables and determines whether or not the success / failure lottery value is a win.

  The success / failure lottery means 112 acquires a lottery value as an open lottery for determining a normal symbol when the game ball passes through the operation port 68. The success / failure lottery means 112 holds a success / failure table in which the correspondence between the lottery value of the open lottery and the success / failure result is determined, and determines the success / failure result of the open lottery with reference to the success / failure table. In the normal state, the winning / failing table with a probability of 1/256 is referred to, and in the easy entry state, the winning / failing table with a probability of 250/256 is referred to. The lottery value of the normal symbol is temporarily held by the hold control means 116. However, the lottery value is held only when the predetermined hold upper limit number held by the hold control means 116 is not exceeded.

  FIG. 4 is a diagram schematically showing the success / failure determination table. The success / failure determination table in this figure associates determination results of big hits, small hits and misses, and winning / failing lottery values. Depending on the respective range settings, the hit / failure probabilities of big hits and small hits are determined. Is determined. The success / failure lottery means 112 refers to the success / failure determination table of FIG. In the success / failure lottery performed by the success / failure lottery means 112, in the normal state, as shown in FIG. 4 (a), only when the success / failure lottery value falls within the range of 0 to 399 is a big hit. At the time of certainty change, as shown in FIG. 4B, the range of the big hit is expanded, and not only when the winning / losing lottery value falls within the range of 0 to 399 but also when the lottery falls within the range of 400 to 2999. Thus, the range corresponding to the big hit changes according to the gaming state. In the case of hitting a big hit, whether it is a 15R big hit or a 2R big hit and whether or not there is a probability change is determined separately according to the stop symbol of the special symbol. In this figure, the single hit / fail judgment table shows the big hit range for both normal time and probability change, but the success / fail judgment table may be prepared separately for normal time and for probability change.

  In the present embodiment, even if the winning / raising lottery value does not correspond to the big hit range, that is, a so-called out of range, it becomes a small hit if it falls within the predetermined range. In the example of this figure, when the success / failure lottery value acquired by the success / failure lottery means 112 falls within the range of 65000 to 65535, it is a small hit. In this way, if it does not correspond to the big hit, it is all “out”, but in the example in this figure, the winning lottery value range when it does not correspond to the small hit out of the cases where it does not correspond to the big hit Is expressed as “displacement”. In addition, although the example which implement | achieved the determination table of whether it is a big hit and the determination table of whether it is a small win in the figure in the form of a single winning / nothing determination table was shown in this figure, each may be implement | achieved as a separate table. Good.

  Returning to FIG. 3, the determination result by the success / failure lottery means 112 is variably displayed in a special symbol form on the special symbol display device 61. In addition, a decorative symbol that shows the determination result by the success / failure lottery means 112 in an effect manner is variably displayed on the effect display device 60. The success / failure lottery means 112 transmits the lottery result corresponding to the symbol variation to the symbol mode determining unit 131 and the effect determining unit 132 together with the symbol variation control command at the timing of starting the symbol variation.

  The symbol determination means 114 determines the stop symbol of the special symbol to be displayed on the special symbol display device 61 according to the lottery result by the success / failure lottery means 112. The symbol determination means 114 holds a symbol range table to be referred to in order to determine a special symbol stop symbol. The symbol determination means 114 acquires a symbol determination lottery value for determining a special symbol, and determines the stop symbol of the special symbol according to the determination result of the success / failure lottery means 112 and the symbol determination lottery value.

  The symbol determination means 114 determines the stop symbol of the normal symbol to be displayed on the normal symbol display device 59 according to the result of the open lottery by the success / failure lottery means 112. The symbol determination means 114 determines the stop symbol of the normal symbol according to the result of the open lottery in order to display the result of the open lottery in the normal symbol display device 59 in the form of a normal symbol. When the determined stop symbol becomes a predetermined symbol, it is determined that the normal symbol is a hit, and after the change display of the normal symbol is stopped at the stop symbol, the opening / closing control means 124 expands the start port 62. The opening mechanism 63 is expanded for a predetermined time.

  The symbol determination unit 114 sends data indicating the determined stop symbol to the main display control unit 118, the symbol mode determination unit 131, and the effect determination unit 132.

  FIG. 5 is a diagram schematically showing a symbol determination table. FIG. 5A is a table that is referred to when the determination result is a big hit, FIG. 5B is a table that is referred to when the result of determination is wrong, and FIG. This table is referred to when the determination result is a small hit. The symbol determination means 114 refers to the symbol determination table of this diagram in symbol determination. In each symbol determination table, the correspondence between the special symbol represented by the numbers “0” to “9” and the symbol “−” and the symbol lottery value is defined. Each type of special symbol is associated with the result of determining whether or not the big hit, small hit, or missed, the odd number corresponds to the big hit, the even number corresponds to the small hit, and the symbol “-” is out. Correspond.

  As shown in FIG. 5A, the special symbols “1”, “3”, “5”, “7”, and “9”, which are odd numbers among the special symbols “0” to “9”, are associated with the jackpot. . Among them, the special symbol “7” indicates a 15R jackpot with certainty and is associated with a symbol lottery value range “0 to 99”. The special symbol “3” indicates a 2R jackpot with certainty and is associated with a symbol lottery value range “100 to 149”. Special symbols “1”, “5”, and “9” indicate 15R big hits without any probability change, the special symbol “1” is associated with the symbol lottery value range “150 to 189”, and the special symbol “190 to 229”. “5” is associated with, and “230 to 255” is associated with the special symbol “9”.

  As shown in FIG. 5B, the special symbol “-” is associated with the entire range of symbol lottery values in the case where the determination result is wrong.

  As shown in FIG. 5C, the special symbols “0”, “2”, “4”, “6”, and “8” that are even numbers among the special symbols “0” to “9” are associated with the small hits. Yes. The special symbol “0” is associated with the symbol lottery value range “0 to 49”, and the special symbol “2” is associated with the symbol lottery value range “50 to 99”. The special symbol “4” is associated with the symbol lottery value range “100 to 149”, the special symbol “6” is associated with the symbol lottery value range “150 to 199”, and the special symbol “8” is the symbol lottery. Corresponding to the value range “200 to 255”.

  Returning to FIG. 3, the variation pattern determination unit 115 selects any variation pattern from a plurality of types of variation patterns according to the result of the success / failure lottery. The variation pattern determining means 115 holds a pattern selection table to be referred to in order to determine the variation pattern. The symbol determination unit 114 sends data indicating the determined variation pattern to the main display control unit 118, the symbol mode determination unit 131, and the effect determination unit 132. The variation pattern determination unit 115 stores a plurality of types of variation patterns. A plurality of types of variation patterns are defined on the assumption that there are various variation times, short and long, and that symbol variation is also performed by a decorative symbol composed of a plurality of symbols in the variation time. In each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol and the decorative symbol is stopped when the variation display time elapses.

  FIG. 6 is a diagram schematically showing the variation pattern table. The variation pattern determining means 115 refers to the variation pattern table for removal shown in FIG. 6A when the result of the determination is wrong. When the determination result is a 15R jackpot, the fluctuation pattern table for 15R jackpot shown in FIG. 6B is referred to. When the determination result is 2R big hit or small hit, the variation pattern table for 2R big hit and small hit shown in FIG. 6C is referred.

  In FIG. 6A, the pattern lottery values 0 to 10 are associated with a super reach “super 1”, and the pattern lottery values 11 to 20 are associated with a super reach “super 2”. The pattern lottery values 21 to 255 are associated with any variation pattern of “normal 1”, “normal 2”, and “no reach”. As described above, when the result of the determination is wrong, any one of super reach, normal reach, and no reach may be selected. In the variation pattern table for detachment, when a variation pattern of “no reach” is selected, a different table is referred to so that a variation pattern having a shorter variation time than the normal state is selected in the short time state. Further, the deviation variation pattern table is defined so that the column to be referred to is different depending on the number of holdings, and details of the normal state will be described later with reference to FIG.

  In FIG. 6B, the super lot of “super 1” is associated with the pattern lottery values 0 to 120, and the super reach of “super 2” is associated with the pattern lottery values 121 to 240. The pattern lottery values 241 to 250 are associated with the reach of “normal 1”, and the pattern lottery values 251 to 255 are associated with the reach of “normal 2”. As described above, when the determination result is 15R big hit, the variation pattern with reach is selected.

  In FIG. 6C, the pattern lottery values 0 to 122 are associated with the super reach “super 3”, and the pattern lottery values 123 to 255 are associated with the normal reach “normal 3”. As described above, when the determination result is 2R big hit or small hit, “Super 3” or “Normal 3” is selected with a probability of about 50%.

  Returning to FIG. 3, the fluctuation pattern determination means 115 determines the fluctuation display time of the normal symbol. In the normal state, the variable display time is determined to be 60 seconds, and in the easy entry state, the variable display time is determined to be 6 seconds.

  When there is a new entry at the start port 62 and a new winning / failing lottery is executed, the holding control means 116 displays a new entry when a symbol change corresponding to the previous entry or lottery is displayed. The result of the success / failure lottery based on is suspended until the start of variable display of the symbol corresponding to the lottery. In the present embodiment, as a result of the lottery determination, the number of the lottery is held as a holding ball with an upper limit of four. The success / failure lottery value here includes a success / failure lottery value, a symbol lottery value, and a variation pattern lottery value. The holding control means 116 further holds the usual lottery value acquired by the success / failure lottery means 112 as a holding ball. These numbers of holdings are represented by the number of lighting or blinking numbers of the special symbol holding display device 20 and the normal symbol holding display device 22, respectively.

  The main display control means 118 causes the special symbol display device 61 to display the lottery result by the success / failure lottery means 112 as a variation display of the special symbol 192 according to the variation pattern determined by the variation pattern determination unit 115. The main display control means 118 sets a new symbol variation start condition that the symbol variation display corresponding to the success / failure lottery performed before that has ended. The main display control means 118 transmits a change start command and a change stop command to the effect display control means 134 at the timing for starting and stopping the change display of the special symbol 192. When the variation start command is transmitted, values indicating the determined determination result, the stop symbol, and the variation pattern are transmitted to the effect display control means 134 together with the variation start command. When transmitting the variation stop command, a value indicating the stop symbol is transmitted to the effect display control means 134 together with the variation stop command. Thereby, the fluctuation display by the main display control means 118 and the effect display control means 134 is synchronized, and the interlock is maintained. The main display control means 118 displays the result of the normal symbol lottery on the normal symbol display device 59 as a normal symbol variation display.

  The special game control means 120 indicates that the special game operation condition is established when the special symbol 192 is stopped in a predetermined big hit mode when the success / failure lottery by the success / failure lottery means 112 results in the transition to the special game. A special game is executed by determining and opening the special winning opening 66. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously performed a plurality of times, and is configured by a plurality of unit games with one opening / closing as a unit. Special games include a 15R jackpot that repeats a unit game 15 times and a 2R jackpot that repeats a unit game that has a shorter opening time than the 15R jackpot only twice. In the case of 15R jackpot, in principle, the big winning opening 66 is opened for about 30 seconds in one unit game. In the case of 2R big hit, the big winning opening 66 is opened for about 0.5 seconds in one unit game. The special game control means 120 ends the special game when the set round number of unit games is exhausted. Even in the case of 2R big hit, if the predetermined condition is satisfied, the big winning opening 66 may be opened in the same manner as the 15R big hit.

  The specific game executing means 122 controls the normal game in the probability changing state, the short time state, and the easy-to-enter state. The specific game execution means 122 shifts the game state to the time-saving state and the easy-to-enter state after the end of the special game. On the other hand, the transition to the probability variation state after the end of the special game is limited to the case where the symbol determined by the symbol determination means 114 is a big hit symbol accompanied by the transition to probability variation. The short-time state and the easy-to-enter state are continued until the number of times of display of the special symbol 192 reaches a predetermined number of end conditions, for example, 100 times from the end of the special game. However, when the state changes to the probability changing state at the same time, as long as the probability changing state continues, the short time state and the easy entry state are continued. That is, it continues until the next big hit occurs. Thus, the end of the short time state and the easy entry state is determined according to the gaming state. In the short time state, the fluctuation pattern determining means 115 selects a fluctuation pattern having a short fluctuation time so that the fluctuation display time of the special symbol 192 is substantially shortened. However, in a normal state, a variation pattern table corresponding to the number of holds of the result of lottery determination by the hold control unit 116 is referred to, and a change pattern with a long variation time is likely to appear as the number of hold by the hold control unit 116 decreases. In the easy entry state, the normal symbol time is shortened, the normal symbol probability change, and the expansion mechanism 63 is opened and extended. On the other hand, the probability variation state is continued until a special game with the next jackpot is executed. During the probable change state, the probability that the success / failure determination result by the success / failure lottery means 112 is a big hit is maintained at a high value.

  The opening / closing control means 124 controls the opening / closing of the ordinary electric accessory at the start opening 62 and the special winning opening 66. When the normal symbol is stopped at a specific symbol, the opening / closing control unit 124 sends an opening instruction to the ordinary electric accessory solenoid 76 to open the start port 62. Further, the opening / closing control means 124 sends an opening instruction to the special winning opening solenoid 80 during the special game, and opens the special winning opening 66.

  The winning rate calculating means 126 calculates the winning rate to the general winning opening 72 based on the general winning information received from the winning determining means 110. Each time the winning rate calculating means 126 receives the general winning information from the winning determining means 110, it counts the number as the number of entered balls, and a predetermined period, for example, 10 minutes, based on the number of entered balls and the elapsed time from the start of counting. The number of winning balls per game is calculated and used as the winning rate for the general winning opening 72. Counting the number of balls entered starts at a predetermined timing after the pachinko gaming machine 10 is turned on. For example, it may be started when the first general winning information is received after the power is turned on, or may be started when the first game ball is fired after the power is turned on. The entrance rate calculation means 126 acquires information indicating whether the game ball is on or off from the launch control board 47. Calculated using the number of entered balls when the counting period of the entered game continues without any special games until at least 10 minutes have passed as the lower limit time after counting the number of entered balls at the predetermined opportunity The rate of entering the general winning award 72 is an effective calculation result.

  If the player interrupts the game before the lower limit time elapses and stops firing the game ball for a certain period of time, when the game is resumed, counting may be resumed for the remaining time until the lower limit time. The counting may be performed again from the beginning until the lower limit time is reached. Even if a special game occurs before the elapse of the lower limit time, counting may be resumed for the remaining time until the lower limit time in the normal game after the end of the special game, or until the lower limit time is reached from the beginning You may recount. The winning rate calculating means 126 holds the data until the end of the power supply after obtaining the effective calculation result as the winning rate to the general winning port 72 in the normal game, and the general winning port 72 in the subsequent normal game. There is no need to calculate the entrance rate to the.

  The entrance rate calculation means 126 calculates the entrance rate to the general winning opening 72 in the special game every time the special game is started. For example, every time a special game is started, the number of balls entered per 10 minutes is calculated based on the number of balls entered into the general prize opening 72 during the special game and the time of the special game, and this is calculated as the general prize in the special game. The entrance rate to the mouth 72. However, depending on the type of special game, there is a case where an effective entrance rate cannot be calculated. In this case, the calculation process is skipped or the calculation result is invalidated. For example, in the case of 2R big hit, since the special game time is extremely short, it is unlikely that it would be normal to enter the general winning opening 72 within that period, but if it happens accidentally at the right time Even if there is no fraud when converted to the number of balls entered per 10 minutes, there is a possibility that it will become an unexpectedly large value. Also, it is unlikely that an illegal player will behave illegally until the 2R jackpot, which is an extremely short period of time, and even if an illegal act is performed, the effect is extremely small. Therefore, the special game of 2R jackpot is not subject to calculation of the rate of entering the general winning opening 72.

  The error determination means 128 acquires from the winning rate calculation means 126 the winning rate to the general winning opening 72 in the normal game and the winning rate to the general winning opening 72 in the special game. The error determination means 128, after acquiring the winning rate to the general winning opening 72 in the special game, has not yet acquired the winning rate to the general winning port 72 in the normal game, after the execution of the special game The rate of entering the general winning opening 72 in the normal game is acquired. The error determination means 128 includes a rate of entering the general winning opening 72 in the normal game acquired before and after the special game, and a rate of entering the general winning slot 72 in the special game acquired every time the special game is started. When the game is complete, the ratio of the entrance rate in the normal game and the entrance rate in the special game is calculated.

  When the ratio of the entrance rate in the normal game and the entrance rate in the special game exceeds a predetermined reference ratio, the error determination unit 128 transmits information indicating an error to the effect determination unit 132 or the effect display control unit 134. The effect display device 60 is notified of the error, and the error determination unit 128 outputs information indicating the error to the hall computer as the external device 300. The hall computer is a collective term for gaming machine management computers prepared by a gaming store. Each gaming machine is connected to the hall computer, and the hall computer collects information on each gaming state from each gaming machine in the gaming store. Information indicating an error is transmitted to the amusement store side to report an action suspected of fraud, so that the amusement store can immediately take appropriate measures.

  The reference ratio between the entrance rate in the normal game and the entrance rate in the special game is determined based on an experimental value or a design value at the design stage of the gaming machine. For example, when the average rate of entrance to the general winning opening 72 in a normal game is 3 in 10 minutes and the standard deviation σ is 1, the range of the entrance rate is average μ ± 3σ. It is considered that it is almost within the range of 0 to 6 at the maximum. In this case, it is considered that a maximum error can occur up to twice the average entrance rate, and the reference ratio may be set to a value such as 1: 2.5 or 1: 3 as a certain value with a margin. Good. In fact, even if the rate of entering the general winning opening 72 in a normal game is about 3 in 10 minutes, an unauthorized player will win a large number of prize balls during a limited period of special games. There is a possibility that fraudulent entry may occur at such a frequency that the entrance rate to the mouth 72 is 150 in 10 minutes. Therefore, fraudulent acts can be detected sufficiently even with reference ratio values such as 1: 2.5 and 1: 3. Alternatively, in order to more surely eliminate erroneous detection based on errors, even if a value such as 1:10 is used as a more sufficient reference ratio, fraud can be detected sufficiently.

  The pattern storage means 130 holds a plurality of effect patterns in which effect image contents to be displayed on the effect display device 60 in the variation of the decorative design 190 and the display process thereof are determined. The effect pattern is displayed separately from a plurality of variable effect patterns in which the change process from start to stop of the change and the change process in the change display of the decorative pattern 190 and the change display of the decorative pattern are displayed, and the degree of expectation for the jackpot And a plurality of notice effect patterns that suggest the height of the notice before the change display stops.

  The effect determining means 132 determines the contents of the effect displayed on the effect display device 60 by the effect display control means 134 according to the result of the success / failure lottery received from the success / failure lottery means 112. The effect determining means 132 selects one of a plurality of change effect pattern data corresponding to the change pattern of the special symbol determined by the change pattern determining means 115, reads out the data from the pattern storage means 130, and obtains information on the change effect pattern. This is sent to the effect display control means 134. The effect determining means 132 holds a pattern table that should be referred to in order to select a variable effect pattern.

  Each variation effect pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. The effect determining unit 132 selects a variation effect pattern of the effect image having the same variation time according to the variation pattern of the special symbol.

  The symbol form determining means 131 determines the combination of stop symbols of the decorative symbol 190 and their arrangement according to the result of the lottery by the winning / failing lottery means 112, the special symbol stop symbol, the special symbol variation pattern, and the decorative symbol variation effect pattern. decide. The symbol form determination unit 131 transmits information indicating the determined combination of stop symbols to the effect display control unit 134. The symbol form determining means 131 holds a symbol range table to be referred to in order to determine the stop symbol of the decorative symbol.

  The stop symbol of the decorative symbol 190 is formed as a combination of three symbols. For example, when the determination result of the success / failure lottery means 112 indicates a transition to a special game of 15R jackpot, a specific combination such as “777” or “ A combination of three symbols such as “111” is selected. In this case, it is preferable that the same numbers as the special symbols 192 are selected as the numbers to be arranged as the decorative symbols 190, but the numbers may not necessarily be the same. For example, when the special symbol 192 is “7”, the decorative symbol 190 is “777”. A specific combination, for example, a predetermined combination such as “357” is also selected when the result of the determination is a 2R big hit or a small hit, but the specific combination is not necessarily a combination of three symbols. It does not have to be. When the determination result is neither big hit nor small hit, it is a combination in which three symbols such as “312” and “946” are not arranged, and a specific combination selected at the time of 2R big hit or small hit A combination that does not apply is selected. When the determination result is not 15R big hit, and a variation pattern indicating a loss with reach is selected, a combination with only one symbol such as “191” or “727” is selected. .

  The notice effect pattern is an effect pattern for temporarily displaying an image, animation, video, or the like of a specific character or motif, or an effect pattern for outputting a specific sound. The effect by the notice effect pattern is executed in parallel with the symbol variation, and suggests that the symbol variation is highly expected to stop in the big hit mode. For example, there are a normal notice effect in which only one character image is displayed on the screen, and a group notice effect in which a large number of characters are displayed so as to pass from one end to the other end of the screen. Further, the display process of the notice effect is divided into a plurality of stages, and the number of stages to be displayed is made variable, and a step-up notice effect that is set such that the greater the number of stages is, the higher the degree of expectation for the big hit is included.

  The notice effect pattern includes a pattern in which the effect is executed at a timing after the display form of the decorative symbol 190 reaches the reach state and the final stop state of the symbol is notified, and no decorative symbol 190 is stopped. There is a pattern in which the performance is executed at the timing and the reach is reached at the same time.

  The effect determining means 132 determines whether or not to display the notice effect on the effect display device 60 according to the result of the lottery determination, makes a pre-effect setting, and determines the notice effect pattern to be displayed. To do. The effect determining means 132 holds a notice determination table that should be referred to in order to determine whether or not to display the notice effect, and a notice type table that should be referred to when selecting the type of the notice effect pattern. The notice decision table is set so that different columns are referred to depending on the result of the lottery, and if the lottery is a win, the notice lottery will be displayed with a higher probability than if it was missed. Correspondence between whether to display the result and the notice effect is determined. Thereby, the high expectation degree to the big hit can be suggested by displaying the notice effect itself.

  The effect display control means 134 displays the effect image including the decorative pattern on the effect display device 60 according to the selected change effect pattern data as a result of the success / failure lottery by the success / failure lottery means 112. The effect display control means 134 starts a new symbol variation when a variation start command for the decorative symbol 190 is received.

  When it is determined by the effect determining unit 132 that the notice effect is displayed, the effect display control means 134 superimposes the notice effect in accordance with the selected notice effect pattern on the effect of symbol variation to the effect display device 60. Display. The effect display control means 134 further controls effect processing such as lighting and extinguishing of the game effect lamp 90 and sound output from the speaker 18.

  In accordance with the instruction received from the effect display control means 134, the accessory control means 136 causes the movable accessory 140 to act in an effect manner in accordance with the effect contents in the effect display device 60 and the blinking process of the game effect lamp 90.

  FIG. 7 is a diagram showing in detail a variation pattern table for detachment. In the variation pattern table 210 of this figure, the range of the pattern lottery value associated with the variation pattern is different for each number of holds. Specifically, the smaller the number of holds, the wider the range of pattern lottery values assigned to variation patterns with relatively long variation times, and the probability that variation patterns with long variation times will be selected is increased. . Therefore, the average fluctuation time becomes longer as the number of holdings by the holding control means 116 is smaller. Accordingly, when the number of holds by the hold control unit 116 is less than a predetermined number, for example, 1 to 2, the selection probability of the change pattern having a long change time becomes higher than usual, and the change time tends to be relatively long.

  The first column 212 shows the correspondence between the pattern lottery value range and the variation pattern when the number of holds as a result of the lottery determination by the hold control means 116 is one. Similarly, in the second column 214, the third column 216, and the fourth column 218, the correspondence between the pattern lottery value range and the variation pattern in the case where the number of holdings as a result of the lottery determination by the holding control means 116 is 2, 3, and 4, respectively. The relationship is shown. That is, it can be considered that the first column 212, the second column 214, the third column 216, and the fourth column 218 indicate the variation pattern table for each number of holds. In this figure, an example will be described in which a plurality of variation patterns that can be selected at the time of deviation are classified into five types according to variation time, but actually, a plurality of variation effect patterns are prepared for each of these classifications. This is equivalent to the fact that dozens of types of variation effect patterns are associated with the lottery value ranges for each category. In order to compare the ratio of each pattern lottery value range in the second column 214, the third column 216, and the fourth column 218 in this figure with the ratio of the pattern lottery value range in the first column 212, Broken lines indicating the ratio of the pattern lottery value range are drawn in the second column 214, the third column 216, and the fourth column 218.

  The first range 222 includes any of the first column 212, the second column 214, the third column 216, and the fourth column 218 as a variation pattern when the lottery value corresponds to a pattern lottery value from 0 to 10. A super reach variation pattern of “super 1” is associated. The second range 224 includes any of the first column 212, the second column 214, the third column 216, and the fourth column 218 as a variation pattern when the lottery value corresponds to a pattern lottery value from 11 to 20. A super reach variation pattern of “super 2” is associated. Thus, in the case of the pattern lottery value with the lottery value from 0 to 10 and the pattern lottery value with the lottery value from 11 to 20, the variation pattern having the same variation time is selected regardless of the number of holdings.

  The third range 226 includes normal reach in the first column 212, the second column 214, the third column 216, and the fourth column 218 as a variation pattern when the lottery value corresponds to a pattern lottery value from 21 to 255, respectively. “Normal 1”, “Normal 2”, and “Reach without reach” are associated with each other. However, the range of pattern lottery values associated with each variation pattern varies depending on the number of holds. In the first column 212, the sizes of the lottery value ranges to which “normal 1”, “normal 2”, and “no reach” are associated are approximately equal, and the ranges obtained by dividing 21 to 255 into approximately three equal portions are associated with each other. Yes. On the other hand, in the second column 214, the size of the lottery value range associated with “normal 1” and “normal 2” is smaller than the lottery value range associated with “no reach”. Further, in the third column 216 and the fourth column 218, the size of the lottery value range associated with each of “normal 1” and “normal 2” is further reduced.

  The fluctuation time of “Normal 1” and “Normal 2” may be longer than the fluctuation time of “Out of reach”, and in the case of “Out of reach”, the fluctuation time may be shortened like a short time state. Depending on the setting contents of the third range 226, the average variation time varies. The pattern lottery value range for “Normal 1” and “Normal 2” decreases as the number of holds increases from 0 to 1, 2, 3, 4, and conversely the pattern lottery value range for “out of reach” increases. Therefore, the average fluctuation time becomes shorter as the number of holds increases, and conversely, the average change time becomes longer as the number of holds decreases. In this way, by using a variation pattern table in which the correspondence between the pattern lottery value range and the variation pattern is different for each number of holdings, control that makes it easy to select a variation pattern with a long variation time when the number of holdings decreases is realized. be able to.

  The variation pattern of “out of reach” associated with the third column 216 has a shorter variation time than the “out of reach” associated with the first column 212 and the second column 214, so-called “shortening variation”. This is the fluctuation pattern. Further, the fluctuation pattern of “out of reach” associated with the fourth column 218 has a shorter variation time than the “out of reach” associated with the first column 212 and the second column 214, and the third column This is a fluctuation pattern of so-called “super-shortening fluctuation” in which the fluctuation time is shorter than “216 shortening fluctuation”.

  FIG. 8 is a flowchart showing a basic operation process in the pachinko gaming machine. First, processing is performed when a game ball enters the start port 62, the general winning port 72, the big winning port 66, etc. (S10). A game control process is executed (S14), and if it is not in a normal game (N in S12), a special game control process (S16) or a small hit game control process is executed (S17), and a winning process in S10 In accordance with the number of prize balls set at, prize ball payout according to various winnings is processed (S18).

  FIG. 9 is a flowchart showing in detail the ball entry process of S10 in FIG. If there is a ball in the starting port 62 (Y in S200), the prescribed number of winning balls corresponding to the starting port 62 is set (S202). If the holding control means 116 refers to whether or not the number of hold of the success / failure lottery value is less than 4 and is in a state where further hold is possible (Y in S204), the success / failure lottery value is acquired (S206). The lottery value is held in the hold control means 116 (S208). In S200, when there is no entry to the starting port 62, the processing from S202 to S208 is skipped (N in S200). If the number of holds reaches the upper limit in S204 and further hold is impossible, the processing of S206 and S208 is skipped (N in S204).

  If there is a ball in the operating port 68 (Y in S210), if the number of holds of the open lottery value by the holding control means 116 is less than 4, and if it can be further held (Y in S212), An open lottery value is acquired (S214), and the open lottery value is held in the hold control means 116 (S218). If there is no ball entering the operating port 68 in S210, the processing from S212 to S218 is skipped (N in S210). If the number of holds reaches the upper limit in S212 and further holding is impossible, the processing from S214 to S218 is skipped (N in S212).

  When there is a winning entry in the general winning opening 72 (Y in S220), a calculation process of the winning rate is executed (S221), and the prescribed number of winning balls corresponding to the general winning opening 72 is set (S222). An error determination process based on the rate is executed (S223), and when there is no entry into the general winning opening 72, the process from S221 to S223 is skipped (N in S220). If there is a ball in the big prize opening 66 (Y in S224), the prescribed number of prize balls corresponding to the big prize opening 66 is set (S226), and if there is no ball in the big prize slot 66, S226 is set. Skip (N in S224).

  FIG. 10 is a flowchart showing in detail the entrance rate calculation process of S221 in FIG. When the game state is normal gaming (Y in S240) and not during the counting period of the number of balls entered to the general winning opening 72 (N in S242), the rate of entering the general winning opening 72 is not calculated. If so (Y in S244), the counting period of the number of balls entered is started (S246), and the number of balls entered into the general winning opening 72 is counted (S248). If the entrance rate to the general winning opening 72 has been calculated (N in S244), the processing of S246 and S248 is skipped. If it is during the counting period of the number of balls entering the general winning opening 72 in S242, the processing from S244 to S246 is skipped (Y in S242). If the game state is a special game in S240 (N in S240), since it always corresponds to the counting period of the number of balls entered, the number of balls entered into the general winning opening 72 is counted (S246).

  FIG. 11 is a flowchart showing in detail the error determination process of S223 in FIG. If it is during the counting period of the number of balls entered into the general winning opening 72 and it is the end timing of the counting period (Y in S260), the counting period is ended (S262), and the general winning opening 72 in the normal game or the special game is ended. The rate of entering the ball, that is, the number of balls entered per 10 minutes is calculated. If both the winning rate to the general winning opening 72 in the normal game and the winning rate to the general winning opening 72 in the special game are already calculated (Y in S266), entering the general winning port 72 in the normal game The ratio of the ball rate and the rate of entering the general winning opening 72 in the special game is calculated (S268). When the rate of entering the general winning opening 72 in the normal game and the rate of entering the general winning slot 72 in the special game are not yet calculated or are not aligned (N in S266), S268 is skipped. If it is not the end timing of the counting period of the number of balls entered into the general winning opening 72 in S260, the processing from S262 to S268 is skipped (N in S260). When the ratio of the entrance rate to the general winning opening 72 in the normal game and the special game exceeds the reference ratio (Y in S270), the error determination means 128 reports an error (S272), and does not exceed the reference ratio. S272 is skipped (N of S270).

  FIG. 12 is a flowchart showing in detail the normal game control process of S14 in FIG. In the normal game control process, if the winning / losing lottery value is on hold (Y in S30) and the symbol variation is not being displayed (N in S32), the winning / losing lottery means 112 executes the determining process. (S34). In accordance with the determination result, the main display control means 118 starts changing display, transmits a change start command to the effect display control means 134, and the effect display control means 134 that receives the command displays the effect image according to the change effect pattern. The fluctuation display is started (S36). If the winning or failing lottery value is not held in S30 (N in S30), the processing from S32 to S36 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 and S36 Is skipped. Subsequently, if the symbol variation display has already started (Y in S38), the symbol variation display process is executed (S40). If the symbol variation display has not started (N in S38), S40 is skipped. .

  FIG. 13 is a flowchart showing in detail the success / failure determination process of S34 in FIG. First, the success / failure lottery means 112 reads the success / failure lottery value (S42), and determines the success / failure based on the success / failure lottery value (S44). The symbol determining means 114 determines the stop symbol of the special symbol based on the result of the determination (S46), and the variation pattern determining means 115 selects the variation pattern of the special symbol (S48). The effect determining means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S50), and selects the variation effect pattern of the decorative symbols according to the variation pattern of the special symbols (S52).

  FIG. 14 is a flowchart showing in detail the special game control process of S16 in FIG. If the result of the lottery is a big hit (Y in S90), the special game has already started (Y in S92), and the grand prize opening 66 has not been opened (N in S98), the big prize opening The release process 66 is executed (S100). At this time, display of the set jackpot effect is also started. If the big prize opening 66 has been opened (Y of S98), the closing process of the big prize opening 66 is executed (S102). As a result, if the special winning opening 66 is closed (Y in S104), the process proceeds to S106. If it is not in the closed state (N in S104), the process after S106 is skipped, and this process is temporarily ended. On the other hand, if the special game has not started in S92 (N in S92), the special game is started (S94), the display of the start demonstration effect is started (S96), and this process is temporarily ended.

  In S106, it is determined whether or not a demonstration production, which is a production during a special game, is being performed. Note that the “demonstration effect” here includes a start demonstration effect and an end demonstration effect. If the demonstration is not in progress (N in S106), it is determined whether or not a special game end condition is satisfied with reference to an end flag described later (S110), and if the special game end condition is satisfied (S110). Y) After the end flag is turned off (S112), display of the end demonstration effect is started (S114). If the special game end condition is not satisfied (N in S110), this process is temporarily ended. If it is determined in S106 that the demonstration effect is being performed (Y in S106), and the end demonstration effect is completed (Y in S116), the special game is terminated (S118), and the specific game, that is, the probability change, the time reduction, and the entry The easy state is started (S120). If the end demonstration effect has not ended (N in S116), the processes in S118 and S120 are skipped. If it is not a big hit (N in S90), the flow after S92 in this figure is skipped.

  FIG. 15 is a flowchart showing in detail the release process of S100 in FIG. When the opening timing of the special winning opening 66 based on the set opening / closing pattern is reached (Y in S122), the opening / closing control means 124 uniformly turns off the passage flag and sets the operation of the opening / closing pattern (S124). The special winning opening 66 is opened (S126). In addition, a big hit effect corresponding to the number of repetitions of the current unit game or a big hit effect corresponding to the number of repetitions being different is set and started. When it is not the opening timing (N of S122), the processes of S124 and S126 are skipped.

  FIG. 16 is a flowchart showing in detail the closing process of S102 in FIG. When the closing timing of the special winning opening 66 based on the set opening / closing pattern is reached, the open / close control means 124 closes the special winning opening 66. That is, during a special game, whether the end condition based on the number of balls is satisfied (Y in S130) or the end condition based on the number of balls is not satisfied (N in S130), the end condition based on the opening time is satisfied ( (Y of S132), the special winning opening 66 is closed (S134). If the termination condition based on the opening time is not satisfied (N in S132), the flow after S134 is skipped.

  The end condition based on the number of balls in the 15R jackpot is 10 or more balls entering the grand prize opening 66, and the end condition based on the opening time is a set time according to the opening / closing pattern from the opening start of the big prize opening 66. It is progress. In the case of 15R big hit, 30 seconds have elapsed since the start of opening, and in the case of 2R big hit, 0.5 seconds have elapsed since the start of opening. However, since the opening for 0.5 seconds is extremely short, it is difficult to enter more than 10 balls as well as to enter the ball itself. Even if a game ball is launched at the same time as the opening of the grand prize opening, it is difficult to enter the game, so it is predicted that the 2R big hit will be opened before the grand prize opening 66 is opened. It is necessary to launch a game ball. On the other hand, the end condition based on the number of balls in the 15R jackpot is 10 or more balls entering the grand prize opening, and the end condition based on the opening time is 30 seconds from the start of opening the big prize opening 66. At this time, if the maximum number of continuations has been reached (Y in S136), the end flag is turned on (S138). If the maximum number of continuations has not been reached (N in S136), the process in S138 is skipped. In this embodiment, the upper limit number of continuations is 15 times. If neither the end condition based on the number of entered balls nor the end condition based on the opening time is satisfied (N in S130, N in S132), the processes after S134 are skipped.

  FIG. 17 is a flowchart showing in detail the small hit game control process of S17 in FIG. If the result of the lottery is a small hit (Y in S150), the small hit game has already started (Y in S152), and the big winning opening 66 has not been opened (N in S158). A process for opening the winning opening 66 is executed (S160), and if it is already opened (Y in S158), a closing process for the big winning opening 66 is executed (S162). As a result, if the special winning opening 66 is closed (Y in S164), the process proceeds to S166. If it is not in the closed state (N of S164), the process after S166 is skipped and this process is temporarily ended. On the other hand, if the small hit game has not started in S152 (N in S152), the small hit game is started (S154), and the display of the start demonstration effect similar to the 2R big hit is started (S156). Exit once.

  In S166, it is determined whether or not a demonstration effect which is an effect during the small hit game is being performed. If the demonstration effect is not in progress (N in S166), it is determined whether or not the small hit game end condition is satisfied. Here, if an end flag, which will be described later, is on, the small hit game end condition is satisfied. If the small hit game end condition is satisfied (Y in S170), the end flag is turned off (S172), and the display of the end demonstration effect is started (S174). If the small hit game ending condition is not satisfied (N in S170), this process is temporarily ended. When it is determined in S166 that the demonstration effect is being performed (Y in S166) and the end demonstration effect is completed (Y in S176), the small hit game is terminated (S178). If the end demonstration effect has not ended (N in S176), the process of S178 is skipped. If it is not a small hit (N in S150), the flow after S152 in this figure is skipped.

  FIG. 18 is a flowchart showing in detail the release process of S160 in FIG. When it is the opening timing of the big winning opening 66 based on the set opening / closing pattern (Y in S180), the opening / closing control means 124 sets the operation of the opening / closing pattern (S182) and starts opening the big winning opening 66. (S184). When it is not the opening timing (N of S180), the processing of S182 and S184 is skipped.

  FIG. 19 is a flowchart showing in detail the closing process of S162 in FIG. When the end timing of the special winning opening 66 based on the set opening / closing pattern is reached (Y in S190), the end flag is turned on (S192), and the special winning opening 66 is closed (S194). This closing timing is the timing when 0.5 seconds have elapsed since the opening of the special winning opening 66. If it is not the closing timing (N of S190), the processes of S192 and S194 are skipped.

(Second embodiment)
This embodiment differs from the first embodiment in that the entrance rate calculating means 126 calculates the entrance rate to the start port 62 instead of the entrance rate to the general winning opening 72. That is, when the ratio of the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game exceeds a predetermined reference ratio, it is determined that there has been an illegal act by an unauthorized player. . Hereinafter, the difference from the first embodiment will be mainly described, and the description of the common points will be omitted.

  In FIG. 3, the entrance rate calculation means 126 calculates the entrance rate to the start port 62. The error determination means 128 notifies an error when the ratio between the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game exceeds a predetermined reference ratio. Usually, since the prescribed number of winning balls for entering the start opening 62 is smaller than the prescribed number of winning balls for entering the general winning opening 72, an unauthorized player can aim at the general winning opening 72 rather than the starting opening 62. Although it is highly probable, according to the present embodiment, even an inconspicuous action of illegally entering the starting port 62 can be detected.

  In FIG. 9, the process of S221 in the first embodiment is executed between S200 and S202, and the process of S223 in the first embodiment is executed between S202 and S204. That is, when a ball enters the starting port 62, the processing corresponding to S221 and S223 is executed regardless of whether or not a new winning / failing lottery value can be held in the holding control means 116.

(Third embodiment)
In this embodiment, when the winning rate to the general winning opening 72 in the normal game is not calculated at the time when the winning rate to the general winning port 72 in the special game is calculated, in the calculated special game This differs from the first and second embodiments in that the entrance rate to the general winning opening 72 is set to the “reference value”. Hereinafter, differences from the first and second embodiments will be mainly described, and description of common points will be omitted.

  If there is no illegal entry to the general winning opening 72 in the special game, the rate of entering the general winning opening 72 in the special game is significantly different from the rate of entering the general winning opening 72 in the normal game. There should be no. For this reason, when the entrance rate to the general winning opening 72 in the special game is calculated without calculating the entrance rate to the general winning entrance 72 in the normal game, the calculated value is once set to the “reference value”. . In the normal game thereafter, the rate of entering the general winning opening 72 in the normal game is calculated as a rule, and the error determining means 128 enters the calculated rate of entry in the normal game and the special game as the “reference value”. The ratio with the rate is calculated. Here, if an illegal entry is made in a special game, the entry rate in the normal game should be much lower than the “reference value”, and the ratio of the entry rate in the normal game and the “reference value” is predetermined. It will exceed the standard ratio. In that case, the error determination means 128 notifies the error, and holds the entrance rate in the normal game after the special game as a new “reference value” until the end of the power supply. On the other hand, if the ratio between the entry rate and the “reference value” in the normal game does not exceed the predetermined reference ratio, it is assumed that there was no illegal entry in the first special game, and the “reference value” is set to the normal value. This is regarded as an effective calculation result as the entrance rate in the game, and is held until the power is finished.

(Fourth embodiment)
In this embodiment, the entrance rate calculation means 126 and the error determination means 128 are provided on the sub-board 104, and the entrance rate calculation means 126 and the error determination means 128 are provided on the main board 102. Different. Hereinafter, the difference from the first to third embodiments will be mainly described, and the description of the common points will be omitted.

  The winning rate calculation means 126 provided on the sub-board 104 receives a command including information indicating a winning to the general winning opening 72 and information indicating a gaming state from the main board 102, and receives a game ball from the launch control board 47. Receives information indicating the firing status. Based on these pieces of information, the entrance rate calculating means 126 calculates the entrance rate to the general winning opening 72 in the normal game and the entrance rate to the general winning opening 72 in the special game. The error determination means 128 provided on the sub-board 104 is used when the ratio of the rate of entering the general winning opening 72 in the normal game and the rate of entering the general winning opening 72 in the special game exceeds a predetermined reference ratio. Judged as an error.

  As a modification, the entrance rate calculation unit 126 may be provided on the main board 102 and the error determination unit 128 may be provided on the sub board 104.

(5th Example)
This embodiment is different from the first to fourth embodiments in that the launch control board 47 stops launching the game ball when the error judging means 128 judges that an error has occurred. Hereinafter, differences from the first to fourth embodiments will be mainly described, and description of common points will be omitted.

  The error determination means 128 controls the information indicating the error when the ratio of the rate of entering the general winning slot 72 in the normal game and the rate of entering the general winning slot 72 in the special game exceeds a predetermined reference ratio. Also transmitted to the substrate 47. Upon receiving the information indicating the error, the launch control board 47 stops the launch of the game ball.

  In the above, this invention was demonstrated based on the Example. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combinations of the respective components and processing processes, and such modifications are also within the scope of the present invention. is there.

  In each of the above-described embodiments, the rate of entering the winning port in the normal game and the rate of entering the winning port in the special game using the rate of entering the general winning port 72 or the rate of entering the starting port 62. The configuration for calculating the ratio of the above has been described. In the modified example, the total of the entrance into the general winning opening 72 and the entrance into the start opening 62 is set as the entrance rate to the entrance, and the entrance rate in the normal game by the total of these entrances The configuration may be such that the ratio of the winning rate to the winning opening in the special game is calculated. Or, by combining the functions of the first embodiment and the function of the second embodiment in one pachinko gaming machine 10, the illegal entry to the general winning opening 72 and the illegal entry to the start opening 62 are separately provided. It is good also as a structure which can be detected easily.

  In the second embodiment or the modification thereof, the configuration in which the entrance rate calculation means 126 calculates the entrance rate to the start port 62 has been described. In a modification, it is good also as a structure which distinguishes and calculates the entrance rate to the starting port 62 in the state which the expansion mechanism 63 of the start port 62 expanded and the entrance in the closed state. Since the start opening 62 has a characteristic that the entrance rate is higher in the state in which the expansion mechanism 63 is expanded than in the closed state, there is a possibility that the ratio of the entrance rate is greatly different depending on whether or not these are distinguished. Therefore, for example, only the state in which the expansion mechanism 63 is closed may be the target of the calculation period, and the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated. Conversely, for example, the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated only for the state in which the expansion mechanism 63 is expanded.

  As another modification, it is good also as a structure which distinguishes the case where the start port 62 is in a ball entering easy state, and the case where it is not so, and calculates the entrance rate to the start port 62. FIG. The start port 62 has a characteristic that the spread mechanism 63 is expanded frequently and long in the easy-to-enter state, and the entrance rate is increased. Therefore, there is a possibility that the ratio of the entrance rate is greatly different depending on whether or not the entrance is easy. Therefore, for example, only the state that is not easy to enter can be used as the target of the calculation period, and the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated. Conversely, for example, the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated only for the easy entry state.

  In each of the above-described embodiments, the configuration has been described in which an error is notified when the ratio of the winning rate to the winning opening in the normal game and the winning rate to the winning opening in the special game exceeds the reference ratio. In the modified example, regardless of whether or not a special game is in progress, the rate of entering the winning opening per predetermined time set as a reference and the entering into the winning opening per predetermined time calculated during the game An error may be notified when the ratio with the rate exceeds the reference ratio.

  In each of the above-described embodiments, if the winning rate in the winning hole in the normal game has not been calculated when the special game occurs, the winning rate in the winning hole in the normal game is calculated after the end of the special game. Explained the configuration. In the modified example, if the winning rate at the winning opening in the normal game has not been calculated at the time when the special game occurs, the data before turning on the power, for example, the winning rate data recorded at the previous business day The ratio of the entrance rate may be calculated using data backed up at the end of the power supply.

(Sixth embodiment)
In this example, if the ratio of the rate of entering the general winning opening in the normal game and the rate of entering the general winning opening in the special game exceeds the judgment value, there is an illegal act by an unauthorized player. judge. In addition, it is determined that there has been an illegal act by an unauthorized player even when the ratio of the number of large winning award prize balls to be paid out in the special game exceeds the predetermined reference ratio. As a fraudulent act, attach an inconspicuous thread-like member such as fishing line to the game ball, enter the general winning opening, and repeat the pulling and relaxation of the thread-like member to react to the general winning opening's entrance sensor many times. Action can be considered. If such an act is executed during a normal game, it may be detected by a function of a gaming machine or a hall computer that detects a sudden increase in the number of prize balls other than a special game. It is conceivable to avoid the execution of fraudulent acts that misuse thread-like members. On the other hand, in the special game, since the number of prize ball payouts is suddenly increased from the beginning, even if an illegal act that misuses the filamentous member is executed, it cannot be detected by the conventional function. For example, in a special game that actually has only 8R unit games, even if there are balls corresponding to 15R unit games, it is not possible to determine whether the game has been played due to fraud. Therefore, in the present embodiment, the rate of entering into the general winning opening is calculated separately during the normal game and the special game, and an illegal winning is detected by comparing these. In addition, the special winning award winning ball payout number and the general winning award winning ball payout number in the special game are distinguished and their ratios are detected, and illegal winnings are detected by comparing these ratios.

  Also, by setting a variable value for the judgment value, even if an unauthorized player obtains and analyzes the gaming machine, the same judgment value is set for the gaming machine in the gaming store. It is not limited, and fraud based on the analysis result can be made difficult. In addition, when it is determined that there has been an illegal act, the fact is notified, but by making the time interval of the notification timing variable from the determination timing, it is also difficult to estimate the determination value based on the notification timing. be able to. Hereinafter, the difference from the first to fifth embodiments will be mainly described.

  In FIG. 2, the sub board 104 is provided with a setting switch 302 (not shown) that is operated when manually setting a determination value to be described later. A person who can access and operate the back side of the pachinko gaming machine 10 such as a game store clerk operates the setting switch 302 to instruct the setting of the determination value.

  FIG. 20 shows functional blocks of the pachinko gaming machine 10 in the present embodiment. In the pachinko gaming machine 10, the game control device 100 includes a start port 62, a big winning port 66, a general winning port 72, an operating port 68, a special symbol display device 61, an effect display device 60, a normal symbol display device 59, and operation buttons 82. , The speaker 18, the game effect lamp 90, the movable accessory 140, the external device 300, and the setting switch 302 are electrically connected to each other so that various control signals can be transmitted and received. In the present embodiment, the main board 102 is a ball determination unit 110, a winning / failing lottery unit 112, a symbol determination unit 114, a variation pattern determination unit 115, a hold control unit 116, a main display control unit 118, a special game control unit 120, a specific game. An execution unit 122 and an opening / closing control unit 124 are provided. In the present embodiment, the sub-board 104 includes a pattern storage unit 130, a design mode determination unit 131, an effect determination unit 132, an effect display control unit 134, an accessory control unit 136, a pitch rate calculation unit 127, and a prize ball number detection unit 129. The error determination means 128 is provided. Each functional block included in the main board 102 may be configured such that any one of the functional blocks is mounted on the sub board 104 instead of the main board 102. Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.

  As a result, counting of the number of balls entered into each winning opening and determination of an error can be processed on the sub-board 104 side. Therefore, the main board 102 transmits a signal indicating the winning into each winning hole to the sub-board 104. Just do it. In the main board 102, for example, the ROM capacity for storing control programs and data is limited to 3 kilobytes, the storage capacity of the RAM is limited to 1 kilobyte, and the use area is limited to 512 bytes. Therefore, the designer wants to increase the storage capacity by reducing the data stored in the ROM or RAM even by 1 byte. Therefore, there is a great design advantage that the program for counting the number of balls entered into the winning opening and the error determination processing program are mounted on the sub-board 104, and it is not necessary to mount them on the main board 102. You can make good use of minutes for different programs. However, as a modification, although the effect relating to the data storage area described above cannot be obtained, it is sufficiently possible to provide the entrance rate calculation means 127 and the error determination means 128 on the main board 102.

  The winning determination means 110 sends start winning information, large winning opening winning information, and general winning information to the winning rate calculating means 127 and the winning ball number detecting means 129.

  The winning rate calculating means 127 calculates the winning rate to the general winning opening 72 based on the general winning information received from the winning determining means 110. Each time the winning rate calculating means 127 receives the general winning information from the winning determining means 110, it counts the number as the number of entered balls, and a predetermined period, for example, 10 minutes, based on the number of entered balls and the elapsed time from the start of counting. The number of winning balls per game is calculated and used as the winning rate for the general winning opening 72. Counting the number of balls entered starts at a predetermined timing after the pachinko gaming machine 10 is turned on. For example, it may be started when the first general winning information is received after the power is turned on, or may be started when the first game ball is fired after the power is turned on. The entrance rate calculation means 127 acquires information indicating whether the game ball is on or off from the launch control board 47. Calculated using the number of entered balls when the counting period of the entered game continues without any special games until at least 10 minutes have passed as the lower limit time after counting the number of entered balls at the predetermined opportunity The rate of entering the general winning award 72 is an effective calculation result.

  If the player interrupts the game before the lower limit time elapses and stops firing the game ball for a certain period of time, when the game is resumed, counting may be resumed for the remaining time until the lower limit time. The counting may be performed again from the beginning until the lower limit time is reached. Even if a special game occurs before the elapse of the lower limit time, counting may be resumed for the remaining time until the lower limit time in the normal game after the end of the special game, or until the lower limit time is reached from the beginning You may recount. The winning rate calculating means 127 holds the data until the end of the power supply after obtaining the effective calculation result as the winning rate to the general winning port 72 in the normal game, and the general winning port 72 in the normal game after that. There is no need to calculate the entrance rate to the.

  As a modified example of the predetermined period for counting the number of entered balls, the number-of-entered calculating means 127 records and stores a log relating to the entered time for the past counting period, for example, at least the past 10 minutes, which goes back from the timing of entering. It is also possible to adopt a configuration in which the number of incoming balls in the past 10 minutes is counted from the incoming timing each time there is a new incoming ball. In this case, since the number of incoming balls is counted every time there is a new incoming ball, it is determined whether or not the determination value has been exceeded at the timing when the new incoming ball has been hit, that is, whether or not fraud has been performed. be able to. Even if the actual elapsed time passes 10 minutes, the log of the entry time etc. is kept without being erased until it is determined that the cumulative period calculated for the first time after the actual entry is 10 minutes. Each time there is a new entry, the log that goes back beyond the cumulative period may be deleted. Alternatively, if the cumulative period is always calculated and divided into an open period and a closed period, the cumulative period is always calculated separately, and whenever it is determined that the cumulative period going back from the current time exceeds the counting period, the excess log It is good also as deleting. Whether or not the counting period has passed is determined for the first time by calculating the cumulative period after the fact, so many frauds can be detected even if a lot of incoming balls exceed the normal expected pace due to fraud. It is desirable to secure a sufficient capacity to record the incoming ball.

  The entrance rate calculating means 127 calculates the entrance rate to the general winning opening 72 in the special game every time the special game is started. For example, every time a special game is started, the number of balls entered per 10 minutes is calculated based on the number of balls entered into the general prize opening 72 during the special game and the time of the special game, and this is calculated as the general prize in the special game. The entrance rate to the mouth 72. However, depending on the type of special game, there is a case where an effective entrance rate cannot be calculated. In this case, the calculation process is skipped or the calculation result is invalidated. For example, in the case of 2R big hit, since the special game time is extremely short, it is unlikely that it would be normal to enter the general winning opening 72 within that period, but if it happens accidentally at the right time Even if there is no fraud when converted to the number of balls entered per 10 minutes, there is a possibility that it will become an unexpectedly large value. Also, it is unlikely that an illegal player will behave illegally until the 2R jackpot, which is an extremely short period of time, and even if an illegal act is performed, the effect is extremely small. Therefore, the special game of 2R jackpot is not subject to calculation of the rate of entering the general winning opening 72.

  The error determination means 128 acquires from the winning rate calculation means 127 the winning rate to the general winning opening 72 in the normal game and the winning rate to the general winning opening 72 in the special game. The error determination means 128, after acquiring the winning rate to the general winning opening 72 in the special game, has not yet acquired the winning rate to the general winning port 72 in the normal game, after the execution of the special game The rate of entering the general winning opening 72 in the normal game is acquired. The error determination means 128 includes a rate of entering the general winning opening 72 in the normal game acquired before and after the special game, and a rate of entering the general winning slot 72 in the special game acquired every time the special game is started. When the game is complete, the ratio of the entrance rate in the normal game and the entrance rate in the special game is calculated.

  The error determination means 128 determines an error when the ratio of the entrance rate in the normal game and the entrance rate in the special game exceeds the determination value, and notifies the error after a grace period has elapsed from the determination. As the determination value, a variable value selected at random from a determination value range determined based on an experimental value or a design value at the design stage of the gaming machine is set. For example, when the average rate of entrance to the general winning opening 72 in a normal game is 3 in 10 minutes and the standard deviation σ is 1, the range of the entrance rate is average μ ± 3σ. It is considered that it is almost within the range of 0 to 6 at the maximum. In this case, it is considered that a maximum error can occur up to twice the average entrance rate, and a determination value is randomly selected from a range of, for example, 1: 2.5 to 1: 3 as a certain value with a margin. May be set. In fact, even if the rate of entering the general winning opening 72 in a normal game is about 3 in 10 minutes, an unauthorized player will win a large number of prize balls during a limited period of special games. There is a possibility that fraudulent entry may occur at such a frequency that the entrance rate to the mouth 72 is 150 in 10 minutes. Accordingly, it is possible to sufficiently detect an illegal act even in a range of determination values from 1: 2.5 to 1: 3. In addition, it is possible to determine that this is a fraudulent entry when an unacceptable amount of entry has occurred at the prize opening, and to make it difficult to guess the judgment criteria from the outside. Can do. That is, even if the fraudulent obtains the pachinko gaming machine 10 and analyzes what numerical value is used as the criterion for the error determination, the numerical value is set to be a variable value. Even if a game is actually played at a game store based on the above, it will not operate as analyzed. Or, even if theoretical analysis is possible if a considerable amount of time is spent, but if effective analysis is impossible unless it takes such a long time compared to other gaming machines, it is fraudulent. It is possible to reduce fraudulent analysis motivation by, and to expect fraud suppression or prevention.

  The error determination unit 128 sets a random value included in a predetermined value range as a determination value every time a predetermined setting timing is reached. The determination value setting timing in this embodiment is the start of the counting period. The error determination unit 128 sets, as the determination value, a random value that is distributed so that the setting frequency for a value close to the boundary value of the determination value range is lower than the setting frequency for a value far from the boundary value. The boundary value is, for example, a lower limit value of the determination value range, and the boundary value is dispersed so that a value close to the lower limit value is set less frequently than a value far from the lower limit value. As for the dispersion of the judgment value, a dispersion value may be set as the judgment value so as to draw a normal distribution curve having a peak value in the middle of the boundary value between the lower boundary value and the upper boundary value. Thereby, it is possible to prevent the boundary value of the determination value range serving as the error determination reference from being easily estimated from the outside. That is, even if a fraudulent person obtains and analyzes the pachinko gaming machine 10, a boundary value with a low setting frequency cannot be easily analyzed, or at least a considerable amount of time is required for analysis, so that fraud can be suppressed or prevented. it can.

  A plurality of candidate values are prepared as a grace period from error determination to error notification, and the error determination means 128 randomly sets one of the candidate values in the grace period, whereby the grace period time value becomes variable. The setting timing of the grace period is at the start of the counting period, similarly to the determination value. As described above, even if the fraudster obtains the pachinko gaming machine 10 and analyzes what kind of numerical value is used as the criterion for error determination, the numerical value and the error notification timing do not necessarily match, and the actual error Since a variable time lag occurs between determination and notification, analysis of the determination value from the outside becomes difficult. Accordingly, it is possible to reduce the willingness to analyze by an unauthorized person and to expect suppression or prevention of fraud.

  The error determination unit 128 holds a plurality of types of candidate ranges as determination value range candidates, and sets any one of the plurality of types of candidate ranges as a determination value range in accordance with an operation of the setting switch 302 by an operator such as a game shop clerk. Set. For example, the setting switch 302 may be provided on the sub-board 104 in the form of a dip switch. The game shop clerk can fine-tune the severity of the judgment criteria according to the condition of the nail adjustment near the winning opening for each gaming machine, and can set an appropriate judgment value to make an appropriate error judgment . However, as a modification, the determination value range may be set according to the operation of the setting switch 302 instead of setting the determination value range. In this case, a plurality of types of candidate values are prepared, and any one of the candidate values is set as the determination value, and no random value is set.

  When the ratio of the entrance rate in the normal game and the entrance rate in the special game exceeds the determination value, it is determined as an error, and after the grace period elapses from the determination, the error determination unit 128 displays information indicating the error. Output to the hall computer as the external device 300. The hall computer is a collective term for gaming machine management computers prepared by a gaming store. Each gaming machine is connected to the hall computer, and the hall computer collects information on each gaming state from each gaming machine in the gaming store. In addition, the error determination unit 128 transmits information indicating the error to the effect determination unit 132 or the effect display control unit 134 to display the error on the screen of the effect display device 60 to notify the error. When the error determination unit 128 notifies the error on the screen of the effect display device 60, the error determination unit 128 maintains the state in which the error is notified until the power of the pachinko gaming machine 10 is turned off. As a result, for example, even if it is designed so that an error is displayed on the screen of the effect display device 60, but the game itself is not stopped, the fact that the error does not disappear as long as the fraudulent person is true. It is difficult to continue the upper game. Thereby, an illegal act can be prevented. In addition, even without the function to stop the game itself, fraudulent acts can be effectively prevented simply by installing a function to notify the error and keep the power off. Measures can be taken. However, as a modified example, it may be configured to prevent further illegal acts by forcibly stopping the launch of the game ball when the error determination means 128 determines an error. As another modification, information indicating an error may be output only to the external device 300 without notifying the screen of the effect display device 60 that an error has occurred. In this case, an error caused by fraud can be made known to the amusement store without being known to the fraudster.

  As described above, fraudulent acts are detected and errors are reported, but it is more reliable to detect fraud by using a plurality of photosensors at the prize opening and directly detecting the raising and lowering of game balls using fishing lines. The nature is high. However, since the sensor itself is designed to increase the cost of hardware, a configuration that can be dealt with only by changing the software as in this embodiment has an advantage of not increasing the manufacturing cost of hardware.

  The winning ball number detecting means 129 is triggered by the number of the big winning award winning ball payouts and the entering of the general winning award 72 when the special game is started every time the special winning game 66 is entered. The number of payouts for the general winning mouth prize balls is detected. In the present embodiment, the number of winning balls in the special game is calculated based on the prescribed number of winning balls for entering the winning game port 66 and the number of balls in the winning game port 66 in the special game. For example, if 10 balls are entered into the grand prize winning port 66, the number of grand prize winning ball payouts is calculated as 150 balls. Also, the winning ball number detecting means 129 calculates the winning ball award payout number in the special game based on the prescribed number of winning balls for the winning in the general winning port 72 and the number of the winning balls in the general winning port 72 in the special game. For example, if 10 balls are entered into the general winning opening 72, the number of paid out general winning prize balls is calculated as 100 balls. The winning ball number detection means 129 receives the big winning information from the winning determination means 110 and counts the number as the number of winning balls to the big winning opening 66 every time the big winning information is received. The winning ball number detection means 129 receives the general winning information from the winning determination means 110 and counts the number as the number of winning balls in the general winning opening 72 every time the general winning information is received.

  The award ball number detecting means 129 detects the number of award winning ball award balls and the number of award winning ball award balls in a special game at the end of the special game. However, depending on the type of special game, there are cases where the effective number of balls cannot be detected. In this case, the detection process is skipped or the detection result is invalidated. For example, in the case of 2R jackpot, the special game time is extremely short, so it would be difficult to enter the big winning hole 66 and the general winning hole 72 within the normal period, but it will be accidentally entered in a timely manner. Even if it is a ball, it becomes a value with no statistical credibility, and there is a risk of an error even if there is no fraud. Also, it is unlikely that an illegal player will behave illegally until the 2R jackpot, which is an extremely short period of time, and even if an illegal act is performed, the effect is extremely small. Therefore, the special game for 2R jackpot is not subject to detection of the number of balls entered to the big winning opening 66 and the general winning opening 72.

  The error determination means 128 obtains the number of award winning ball award balls and the number of award winning ball award for special games from the award ball number detecting means 129, and the number of the award winning ball award balls and the number of award winning award balls. The ratio of the number of payouts is calculated. When the ratio between the number of grand prize winning ball award and the number of general winning award winning ball payout in a special game exceeds a predetermined reference ratio, the error determining means 128 displays information indicating an error as the effect determining means 132 or the effect display control means. The error display unit 60 transmits the information indicating the error to the hall computer as the external device 300. The hall computer is a collective term for gaming machine management computers prepared by a gaming store. Each gaming machine is connected to the hall computer, and the hall computer collects information on each gaming state from each gaming machine in the gaming store. Information indicating an error is transmitted to the amusement store side to report an action suspected of fraud, so that the amusement store can immediately take appropriate measures.

  The reference ratio between the number of special winning award winning ball payouts and the number of general winning award winning ball payouts in a special game is determined based on experimental values or design values at the design stage of the gaming machine. For example, if the average number of payouts for special prize mouths in a special game is 300 on average per minute and the number of payouts on special prize mouths in a special game is on average 3 per minute, The ratio of the number of winning ball award balls is 1/100. Assuming that the player keeps firing the game balls without stopping, and the standard deviation σ of the number of winning prize award balls is 30, the range of the number of winning prize award balls is an average μ ± 3σ. It is considered that it is almost within the range of 210 to 390. Further, when the standard deviation σ of the number of general winning award winning ball payouts per minute is 1, the range of the number of general winning award winning ball payouts is an average μ ± 3σ, and a range of 0 to 6 It is thought that it will fit within. In this case, the ratio of the number of general winning award prize balls paid out to the number of winning prize ball award balls is about 1/35 at maximum if there is no fraud and stop of the game ball launch. Therefore, the reference ratio may be set to a value such as 1/30 or 1/25 as a certain value with a margin. In fact, illegal players can illegally enter a regular winning mouth prize ball at a frequency of 100 or 200 per minute in order to acquire a large number of prize balls during a limited period of special games. There is sex. Therefore, fraudulent acts can be detected sufficiently even with reference ratio values such as 1/10 and 1/5. Alternatively, in order to more surely eliminate erroneous detection based on an error, even if a value such as 1/3 or 1/2 is used as a reference ratio with a further margin, fraud can be detected sufficiently.

  In addition, if the player stops the launch of the game ball for some reason during the special game, the number of the big prize prize ball payout will decrease, but the number of general prize ball payout will also decrease due to the stop of the launch, so the ratio does not change much .

  FIG. 21 is a flowchart showing in detail the ball entry process of S10 in FIG. If there is a ball in the starting port 62 (Y in S400), the prescribed number of prize balls corresponding to the starting port 62 is set (S402). If it is in a state where further holding is possible with reference to whether or not the number of holding of the success / failure lottery value by the hold control means 116 is less than 4 (Y in S404), the success / failure lottery value is acquired (S406). The lottery value is held in the hold control means 116 (S408). If there is no ball entering the starting port 62 in S400, the processing from S402 to S408 is skipped (N in S400). If the number of holds has reached the upper limit in S404 and further hold is impossible, the processing of S406 and S408 is skipped (N in S404).

  If there is a ball in the operating port 68 (Y in S410), if the number of the open lottery value held by the holding control means 116 is less than 4 and if it can be further held (Y in S412), An open lottery value is acquired (S414), and the open lottery value is put on hold control means 116 (S418). If there is no ball entering the operating port 68 in S410, the processing from S412 to S418 is skipped (N in S410). If the number of holds reaches the upper limit in S412 and further holding is impossible, the processing from S414 to S418 is skipped (N in S412).

  If there is a winning ball in the general winning opening 72 (Y in S420), a calculation process of the winning rate is executed (S421), and a prescribed number of winning balls corresponding to the general winning hole 72 is set (S422). An error determination process based on the rate is executed (S423), and when there is no ball entering the general winning opening 72, the process from S421 to S423 is skipped (N in S420). If there is a winning ball in the big winning opening 66 (Y in S424), the counting process of the number of the winning balls is executed (S425), and the prescribed winning ball number corresponding to the big winning hole 66 is set (S426). When there is no entry into the winning opening 66, S425 and S426 are skipped (N in S424).

  FIG. 22 is a flowchart showing in detail the entrance rate calculation process of S421 in FIG. If the gaming state is normal gaming (Y in S440) and not during the counting period of the number of balls entered to the general winning opening 72 (N in S442), the rate of entering the general winning opening 72 is not calculated. If so (Y in S444), the counting period of the number of balls entered is started (S446), and the number of balls entered into the general winning opening 72 is counted (S448). If the entrance rate to the general winning opening 72 has been calculated (N in S444), the processing of S446 and S448 is skipped. If it is during the counting period of the number of balls entering the general winning opening 72 in S442, the processing from S444 to S446 is skipped (Y in S442). If the game state is a special game in S440 (N in S440), since it always corresponds to the counting period of the number of balls entered, the number of balls entered into the general winning opening 72 is counted (S446).

  FIG. 23 is a flowchart showing in detail the error determination processing in S423 in FIG. If it is during the counting period of the number of balls entered into the general winning opening 72 and it is the end timing of the counting period (Y in S460), the counting period is ended (S462), and the general winning opening 72 in the normal game or special game is ended. The rate of entering the ball, that is, the number of balls entered per 10 minutes is calculated. If both the winning rate to the general winning opening 72 in the normal game and the winning rate to the general winning opening 72 in the special game are already calculated (Y in S466), the entering to the general winning port 72 in the normal game is completed. The ratio of the ball rate and the rate of entering the general winning opening 72 in the special game is calculated (S468). When the rate of entering the general winning slot 72 in the normal game and the rate of entering the general winning slot 72 in the special game are not yet calculated or are not aligned (N in S466), S468 is skipped. If it is not the end timing of the counting period of the number of balls entered into the general winning opening 72 in S460, the processing from S462 to S468 is skipped (N in S460). When the ratio of the rate of entry to the general winning opening 72 in the normal game and the special game exceeds the determination value (Y in S470), the error determination means 128 notifies an error (S472), and if the determination value does not exceed the determination value S472 is skipped (N of S470).

  FIG. 24 is a flowchart showing in detail the number-of-entries counting process of S425 in FIG. If the gaming state is a special game (Y in S440), the number of balls entered into the big winning opening 66 is counted (S442), and if not in the special game (N in S440), S442 is skipped.

  FIG. 25 is a flowchart showing in detail the special game control process of S16 in FIG. Details of the special game end process (S118) will be described with reference to the next figure.

FIG. 26 is a flowchart showing in detail the special game end process of S118 in FIG. First, the special game is ended (S464), and the number of the general winning award winning ball paid out based on the number of the balls entered into the general winning opening 72 and the prescribed number of winning balls in the special game and the entering into the large winning port 66 in the special game Based on the number and the specified number of prize balls, the number of prize winning ball payouts is calculated (S466), and the ratio of the number of general prize winning ball prizes paid out and the number of prize winning ball prizes in the special game is calculated (S468). When the ratio of the number of general winning award prize balls to be paid out in the special game exceeds the reference ratio (Y in S470), the error determination means 128 reports an error (S472) and exceeds the reference ratio. If not, S472 is skipped (N in S470).
(Seventh embodiment)
This embodiment differs from the sixth embodiment in that the entrance rate calculating means 127 calculates the entrance rate to the start port 62 instead of the entrance rate to the general winning opening 72. In other words, when the ratio of the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game exceeds the determination value, it is determined that there has been an illegal act by an unauthorized player. Hereinafter, the difference from the sixth embodiment will be mainly described, and the description of the common points will be omitted.

  In FIG. 20, the entrance rate calculation means 127 calculates the entrance rate to the start port 62. The error determination means 128 notifies an error when the ratio of the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game exceeds the determination value. Usually, since the prescribed number of winning balls for entering the start opening 62 is smaller than the prescribed number of winning balls for entering the general winning opening 72, an unauthorized player can aim at the general winning opening 72 rather than the starting opening 62. Although it is highly probable, according to the present embodiment, even an inconspicuous action of illegally entering the starting port 62 can be detected.

  In FIG. 21, the process of S421 in the sixth embodiment is executed between S400 and S402, and the process of S423 in the sixth embodiment is executed between S402 and S404. That is, when a ball enters the starting port 62, the process corresponding to S421 and S423 is executed regardless of whether or not a new winning / failing lottery value can be held in the holding control means 116.

(Eighth embodiment)
In this embodiment, when the winning rate to the general winning opening 72 in the normal game is not calculated at the time when the winning rate to the general winning port 72 in the special game is calculated, in the calculated special game It differs from the sixth and seventh embodiments in that the entrance rate to the general winning opening 72 is set to the “reference value”. In the following, differences from the sixth and seventh embodiments will be mainly described, and description of common points will be omitted.

  If there is no illegal entry to the general winning opening 72 in the special game, the rate of entering the general winning opening 72 in the special game is significantly different from the rate of entering the general winning opening 72 in the normal game. There should be no. For this reason, when the entrance rate to the general winning opening 72 in the special game is calculated without calculating the entrance rate to the general winning entrance 72 in the normal game, the calculated value is once set to the “reference value”. . In the normal game thereafter, the rate of entering the general winning opening 72 in the normal game is calculated as a rule, and the error determining means 128 enters the calculated rate of entry in the normal game and the special game as the “reference value”. The ratio with the rate is calculated. Here, if an illegal entry was made in a special game, the entry rate in the normal game should be much lower than the “reference value”, and the ratio of the entry rate in the normal game and the “reference value” is determined. It will exceed the value. In that case, the error determination means 128 notifies the error, and holds the entrance rate in the normal game after the special game as a new “reference value” until the end of the power supply. On the other hand, if the ratio between the entrance rate in the normal game and the “reference value” does not exceed the judgment value, it is assumed that there was no illegal entry in the first special game, and the “reference value” is set in the normal game. It is regarded as an effective calculation result as the entrance rate and is held until the power is turned off.

(Ninth embodiment)
This embodiment is different from the sixth to eighth embodiments in that the firing control board 47 stops the launch of the game ball when the error judging means 128 judges that an error has occurred. Hereinafter, the differences from the sixth to eighth embodiments will be mainly described, and the description of the common points will be omitted.

  The error determination means 128 displays information indicating an error when the ratio of the rate of entering the general winning opening 72 in the normal game and the rate of entering the general winning opening 72 in the special game exceeds the determination value. Also send to. Upon receiving the information indicating the error, the launch control board 47 stops the launch of the game ball.

(Tenth embodiment)
In the present embodiment, the winning ball number detecting means 129 is not the number of payouts for the general winning port winning ball that is triggered by entering the general winning port 72 but the starting winning port that is triggered by entering the starting port 62. The sixth embodiment is different from the sixth to ninth embodiments in that the number of winning balls is detected. That is, it is determined that there has been an illegal act by an unauthorized player when the ratio of the number of prize winning ball award payouts and the number of start winning award ball payouts in a special game exceeds a predetermined reference ratio. Hereinafter, the differences from the sixth to ninth embodiments will be mainly described, and the description of the common points will be omitted.

  In FIG. 20, the winning ball number detecting means 129 counts the number of balls entered into the starting port 62, and calculates the starting winning port prize ball payout number based on the number of balls entered into the starting port 62 and the prescribed number of winning balls. . The error determination means 128 notifies an error when the ratio of the number of big winning award winning ball payouts and the number of starting winning award winning ball payouts in a special game exceeds a predetermined reference ratio. Usually, since the prescribed number of winning balls for entering the start opening 62 is smaller than the prescribed number of winning balls for entering the general winning opening 72, an unauthorized player can aim at the general winning opening 72 rather than the starting opening 62. Although it is highly probable, according to the present embodiment, even an inconspicuous action of illegally entering the starting port 62 can be detected.

  In FIG. 21, the process of S421 in the sixth to ninth embodiments is executed between S400 and S402. That is, when a ball enters the start port 62, the process corresponding to S421 is executed regardless of whether or not a new winning / failing lottery value can be held in the holding control means 116.

  In the above, this invention was demonstrated based on the Example. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combinations of the respective components and processing processes, and such modifications are also within the scope of the present invention. is there.

(Modification to the first to fifth embodiments)
In each of the above-described embodiments, the rate of entering the winning port in the normal game and the rate of entering the winning port in the special game using the rate of entering the general winning port 72 or the rate of entering the starting port 62. The configuration for calculating the ratio of the above has been described. In the modified example, the total of the entrance into the general winning opening 72 and the entrance into the start opening 62 is set as the entrance rate to the entrance, and the entrance rate in the normal game by the total of these entrances The configuration may be such that the ratio of the winning rate to the winning opening in the special game is calculated. Or, by combining the functions of the first embodiment and the function of the second embodiment in one pachinko gaming machine 10, the illegal entry to the general winning opening 72 and the illegal entry to the start opening 62 are separately provided. It is good also as a structure which can be detected easily.

  In the second embodiment or the modification thereof, the configuration in which the entrance rate calculation means 126 calculates the entrance rate to the start port 62 has been described. In a modification, it is good also as a structure which distinguishes and calculates the entrance rate to the starting port 62 in the state which the expansion mechanism 63 of the start port 62 expanded and the entrance in the closed state. Since the start opening 62 has a characteristic that the entrance rate is higher in the state in which the expansion mechanism 63 is expanded than in the closed state, there is a possibility that the ratio of the entrance rate is greatly different depending on whether or not these are distinguished. Therefore, for example, only the state in which the expansion mechanism 63 is closed may be the target of the calculation period, and the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated. Conversely, for example, the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated only for the state in which the expansion mechanism 63 is expanded.

  As another modification, it is good also as a structure which distinguishes the case where the start port 62 is in a ball entering easy state, and the case where it is not so, and calculates the entrance rate to the start port 62. FIG. The start port 62 has a characteristic that the spread mechanism 63 is expanded frequently and long in the easy-to-enter state, and the entrance rate is increased. Therefore, there is a possibility that the ratio of the entrance rate is greatly different depending on whether or not the entrance is easy. Therefore, for example, only the state that is not easy to enter can be used as the target of the calculation period, and the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated. Conversely, for example, the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated only for the easy entry state.

  In each of the above-described embodiments, the configuration has been described in which an error is notified when the ratio of the winning rate to the winning opening in the normal game and the winning rate to the winning opening in the special game exceeds the reference ratio. In the modified example, regardless of whether or not a special game is in progress, the rate of entering the winning opening per predetermined time set as a reference and the entering into the winning opening per predetermined time calculated during the game An error may be notified when the ratio with the rate exceeds the reference ratio.

  In each of the above-described embodiments, if the winning rate in the winning hole in the normal game has not been calculated when the special game occurs, the winning rate in the winning hole in the normal game is calculated after the end of the special game. Explained the configuration. In the modified example, if the winning rate at the winning opening in the normal game has not been calculated at the time when the special game occurs, the data before turning on the power, for example, the winning rate data recorded at the previous business day The ratio of the entrance rate may be calculated using data backed up at the end of the power supply.

(Modification to the sixth to tenth embodiments)
In the above embodiment, the rate of entrance to the winning entrance in the normal game and the rate of entrance to the entrance in the special game are calculated using the entrance rate to the general winning opening 72 or the entrance rate to the starting port 62. The configuration for calculating the ratio has been described. In the modified example, the total of the entrance into the general winning opening 72 and the entrance into the start opening 62 is set as the entrance rate to the entrance, and the entrance rate in the normal game by the total of these entrances The configuration may be such that the ratio of the winning rate to the winning opening in the special game is calculated. Alternatively, by combining the functions of the sixth embodiment and the seventh embodiment in one pachinko gaming machine 10, unauthorized entry to the general winning opening 72 and unauthorized entry to the start opening 62 are separately performed. It is good also as a structure which can be detected easily.

  In the above-described embodiment or its modification, the configuration in which the entrance rate calculation means 127 calculates the entrance rate to the start port 62 has been described. In a modification, it is good also as a structure which distinguishes and calculates the entrance rate to the starting port 62 in the state which the expansion mechanism 63 of the start port 62 expanded and the entrance in the closed state. Since the start opening 62 has a characteristic that the entrance rate is higher in the state in which the expansion mechanism 63 is expanded than in the closed state, there is a possibility that the ratio of the entrance rate is greatly different depending on whether or not these are distinguished. Therefore, for example, only the state in which the expansion mechanism 63 is closed may be the target of the calculation period, and the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated. Conversely, for example, the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated only for the state in which the expansion mechanism 63 is expanded.

  As another modification, it is good also as a structure which distinguishes the case where the start port 62 is in a ball entering easy state, and the case where it is not so, and calculates the entrance rate to the start port 62. FIG. The start port 62 has a characteristic that the spread mechanism 63 is expanded frequently and long in the easy-to-enter state, and the entrance rate is increased. Therefore, there is a possibility that the ratio of the entrance rate is greatly different depending on whether or not the entrance is easy. Therefore, for example, only the state that is not easy to enter can be used as the target of the calculation period, and the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated. Conversely, for example, the entrance rate to the start port 62 in the normal game and the entrance rate to the start port 62 in the special game may be calculated only for the easy entry state.

  In each of the above-described embodiments, a configuration has been described in which an error is notified when the ratio between the winning rate at a winning hole in a normal game and the winning rate at a winning hole in a special game exceeds a determination value. In the modified example, regardless of whether or not a special game is in progress, the rate of entering the winning opening per predetermined time set as a reference and the entering into the winning opening per predetermined time calculated during the game An error may be notified when the ratio with the rate exceeds the determination value.

  In each of the above-described embodiments, if the winning rate in the winning hole in the normal game has not been calculated when the special game occurs, the winning rate in the winning hole in the normal game is calculated after the end of the special game. Explained the configuration. In the modified example, if the winning rate at the winning opening in the normal game has not been calculated at the time when the special game occurs, the data before turning on the power, for example, the winning rate data recorded at the previous business day The ratio of the entrance rate may be calculated using data backed up at the end of the power supply.

  In each of the above-described embodiments, the configuration in which a random value is set as the determination value for error determination has been described. In a modification, it is good also as a structure which sets a different fixed value for every stand of pachinko gaming machine 10 as a judgment value. In this case as well, it can be said that the “variable value” is different for each stand, so even if the fraudster obtains and analyzes a certain stand, the stand set at the amusement store has a different judgment value. The analysis result cannot be used as it is.

  In each of the above-described embodiments, a configuration for calculating the ratio of the number of winning prize ball award and the number of winning mouth prize balls in a special game by using the number of general winning award ball balls or the starting winning ball award ball number is used. explained. In the modified example, the total number of balls entered into the general winning port 72 and the ball entered into the start port 62 is used as the number of balls entered into the winning port, and the number of winning ball award balls paid out in the special game is calculated based on the total number of these balls entered. In addition, the configuration may be such that the ratio of the number of winning prize ball award payouts and the number of winning prize ball payouts in a special game is calculated. Or it is good also as a structure which can separately detect the illegal entrance to the general winning opening 72 and the illegal entrance to the start slot 62 by having the function of each embodiment in one pachinko gaming machine 10 together.

  In each of the above-described embodiments or modifications thereof, the configuration in which the winning ball number detecting means 129 counts the number of balls entering the starting port 62 has been described. In a modified example, the number of balls entering the start port 62 may be configured to separately count the number of balls entered when the expansion mechanism 63 of the start port 62 is expanded and the number of balls entered when the start port 62 is closed. Since the start opening 62 has a characteristic that the entrance rate is higher in the state in which the expansion mechanism 63 is expanded than in the closed state, the ratio of the number of entrances may greatly differ depending on whether or not these are distinguished. Therefore, for example, only the state in which the expansion mechanism 63 is closed may be the target of the detection period, and the ratio of the number of big winning award winning ball payouts and the number of starting winning award winning ball payouts in a special game may be calculated. On the contrary, for example, the ratio of the big winning award winning ball payout number and the starting winning award winning ball payout number in the special game may be calculated only for the state in which the expanding mechanism 63 is expanded.

  In each of the above-described embodiments, the configuration in which the winning ball number detection unit 129 and the error determination unit 128 are provided on the main board 102 has been described. In the modified example, the prize ball number detecting means 129 and the error determining means 128 may be provided on the sub-board 104.

  In each of the above-described embodiments and modifications, the configuration has been described in which the winning ball number detecting means 129 calculates the winning ball payout number by calculation based on the number of entering balls and the prescribed winning ball number. In the modified example, a prize ball sensor capable of detecting the number of prize balls paid out for each prize ball is provided at a predetermined position in the payout path from the payout unit 43 or the prize ball tank 44 to the upper ball tray 15 or the lower ball dish 16 and is actually installed. The number of prize balls paid out may be detected. As another modified example, each time the winning ball number detecting means 129 enters the general winning port 72 or the starting port 62 and the big winning port 66, the respective predetermined award ball numbers are added up to thereby determine the award for each winning port. It is good also as a structure which calculates | requires the ball payout number.

  In each of the embodiments described above, a configuration is described in which the error determination unit 128 calculates a ratio between the number of winning prize prize ball payouts and the number of winning prize prize ball payouts, and determines an error depending on whether the ratio exceeds a reference ratio. did. In the modified example, the error determination means 128 may calculate the ratio of the number of balls entered into the special winning opening 66 and the general winning opening 72 in the special game, and determine the error depending on whether or not the ratio exceeds the reference ratio. Good.
