Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a fraudulent act which can not be easily found. <P>SOLUTION: The game machine 1 detects the variation starting operation to start a unit game, and symbols necessary for the game are variably displayed according to the variation starting operation. Then, random numbers are extracted for each unit game according to the variation starting operation, and an internal winning hand is determined based on the extracted random numbers. Variable display of the symbols is stopped based on the internal winning hand automatically after the elapse of a prescribed period of time or according to the stopping operation by the player, and game media are given to the player based on the displayed stopped symbols. The game machine 1 calculates the timing of the detected variation starting operation, and determines whether the calculated timing of the detected variation starting operation is a prescribed cycle or not. If the timing of the variation starting operation is the prescribed cycle, the player is informed that the timing of the variation starting operation is the prescribed cycle. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a pachislot machine, a slot machine, a slit slot, a video slot, and other gaming machines that include a display unit that displays a display mode related to a game and a control unit such as a microcomputer that controls the display.

  For example, a slot machine equipped with a stop button, a so-called pachislot machine, has a mechanical variation display device configured by arranging a plurality of rotating reels that variably display a plurality of symbols in the front display window, or a symbol on the screen. It has an electrical fluctuation display device for displaying on. Here, in the case of having a mechanical fluctuation display device, the control means drives and controls the fluctuation display device to rotate each reel in response to the player's start operation, thereby displaying the symbols in a variable manner for a certain period of time. Thereafter, the rotation of each reel is sequentially stopped automatically or by a player's stop operation. At this time, when the symbols of the reels appearing in the display window have a specific combination (winning symbol), a game medium such as a medal or a coin is paid out.

  Currently, the mainstream model has a plurality of types of winning modes. In particular, when a winning combination wins, the game state is better in condition than the normal state for a predetermined period of time, instead of finishing paying out a single medal. As such a role, a role capable of playing a game that gives a relatively large profit to the player (referred to as “big bonus”, hereinafter abbreviated as “BB”) and a game that gives a relatively small profit to the player There is a role that can be played (referred to as “regular bonus”, hereinafter abbreviated as “RB”).

  Also, in the current mainstream model, in order to become a prize where a combination of predetermined symbols is lined up along an activated winning line (hereinafter referred to as “active line”), medals or coins are paid out, A combination of symbols indicating the winning combination of the winning combination (hereinafter referred to as “internal winning combination”) and the winning combination of the internal winning combination (hereinafter referred to as “internal winning combination”) through an effective line The player is required to perform a stop operation at a timing at which the player can stop. In other words, no matter how much the internal winning is made, if the timing of the stop operation of the player is bad, it cannot be won.

  Internal winning combinations (for example, small roles) other than BB and RB, which are called small roles, lose their rights if they are not awarded in the internal winning game. For this reason, the number of medals, coins, etc. that can be acquired will be reduced unless a stop operation (so-called “pressing”) is performed at an appropriate timing. However, if it is configured such that all winning combinations must always be looked for, the number of acquired medals will be greatly different due to the difference in the skills of the players, and beginners will suffer a significant disadvantage. From this, for example, as described in Patent Document 1, the above-mentioned BB, RB, and the like are configured such that the internal winning combination is held until winning.

  This internal winning combination, when a start operation is performed, extracts a count value from a random number counter that is sequentially updated, and refers to the lottery table in which the internal winning combination and the random number range are associated with the extracted count value. Is determined by For example, if the extracted count value is within a random number range corresponding to BB, RB, etc. in the lottery table, BB, RB, etc. are determined as the internal winning combination. Such a random number counter is generally composed of a counter of 14 bits, 16 bits, etc., and is updated at an extremely high speed of increasing by “1” every several MHz. As described above, since the count value is updated at a constant cycle, the same count value is extracted at a certain timing. However, the update cycle is very short, and the player wins the internal winning combination. It has been considered impossible to perform a start operation so as to determine.

However, an illegal act focusing on the fact that the count value is updated at a constant period is a problem. For example, by using a device that can output radio waves with a certain period and shift the phase, the period for winning BB and RB as an internal winning combination is found, and BB and RB are elected as an internal winning combination. Unauthorized actions (so-called “radio waves”) may be performed. Therefore, in the present gaming machines, gaming machines equipped with radio wave detectors that detect radio waves are known, and attempts have been made to prevent unauthorized acts using radio waves.
JP 2003-126333 A

  However, in such a gaming machine, there is a player who performs an illegal action by performing a start operation at a constant cycle without using radio waves or the like. For example, when a solenoid is driven at a certain cycle and the drive is triggered by a start operation and an apparatus capable of shifting the phase at the certain cycle is used, an unauthorized act (so-called “solenoid go”) is performed. It may be done and measures must be taken.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a gaming machine that can prevent an illegal act that is difficult to find.

  In order to achieve the above object, the gaming machine of the present invention provides the following.

  (2) In the gaming machine described in (1), based on the result determined by the timing determination unit, notification means for notifying that the timing of the change start operation is a predetermined timing (for example, a hall described later) A gaming machine comprising a control circuit in a computer).

  According to the invention of (2), the notification means notifies the fact that the timing of the fluctuation start operation is a predetermined period (time) based on the result determined by the timing determination means. When it is determined that the timing of the operation is a predetermined cycle, specifically, a winning combination that is difficult to win frequently or a bonus (for example, BB, RB) is frequently selected as an internal winning combination, etc. An illegal act is notified, and the possibility of preventing the illegal act can be increased, and a more fair game can be provided.

  According to the present invention, the timing determination means determines whether or not the timing of the fluctuation start operation has a predetermined cycle (time), so it is determined that the timing of the variation start operation has a predetermined cycle. In particular, the possibility of detecting an illegal act such as a winning combination that is difficult to win frequently in probability and a bonus (for example, BB, RB) is frequently selected as an internal winning combination is increased.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

[Overview of gaming machines]
FIG. 1 is a perspective view showing an overview of a gaming machine 1 according to an embodiment of the present invention. The gaming machine 1 is a so-called “pachislot machine”. The gaming machine 1 is a gaming machine that uses a game medium such as a card that stores information on game value given to or given to a player in addition to coins, medals, game balls, tokens, and the like. However, in the following description, medals are used.

  A panel display portion 2a as a substantially vertical surface is formed on the front surface of the cabinet 2 forming the entire gaming machine 1, and vertically long display windows 4L, 4C, 4R are provided at the center thereof. The display windows 4L, 4C and 4R are provided with a top line 8b, a center line 8c and a bottom line 8d in the horizontal direction as winning lines, and a cross-up line 8a and a cross-down line 8e in the diagonal direction. These winning lines are respectively operated by operating a 1-BET switch 11, a 2-BET switch 12, and a maximum BET switch 13, which will be described later, or by inserting medals into the medal slot 22, respectively. The book is activated. Which winning line is activated is displayed by turning on BET lamps 9a, 9b, and 9c, which will be described later.

  Inside the cabinet 2, three reels 3L, 3C, 3R each having a symbol row constituted by a plurality of types of symbols on each outer peripheral surface are rotatably provided in a horizontal row to form a variable display means. doing. The design of each reel can be observed through the display windows 4L, 4C, 4R. Each reel rotates at a constant speed (for example, 80 rpm).

  On the left side of the display windows 4L, 4C, 4R, a 1-BET lamp 9a, a 2-BET lamp 9b, a maximum BET lamp 9c, and an information display unit 18 are provided. The 1-BET lamp 9a, the 2-BET lamp 9b, and the maximum BET lamp 9c are turned on according to the number of medals betted to play one game (unit game) (hereinafter referred to as “BET number”). Here, in the present embodiment, one game ends when all reels are stopped. The 1-BET lamp 9a is turned on when the BET number is “1” and one winning line is activated. The 2-BET lamp 9b is lit when the BET number is “2” and three pay lines are activated. The maximum BET lamp 9c is turned on when the number of BETs is “3” and all (5) winning lines are activated. The information display unit 18 is composed of 7-segment LEDs, and displays the number of medals stored (credited), the number of medals paid out when a winning is established, the number of games in the BB general gaming state described later, and the like.

  A horizontal pedestal 10 is formed below the display windows 4L, 4C, 4R, and a liquid crystal display device 5 is provided between the pedestal 10 and the display windows 4L, 4C, 4R. Information related to the game is displayed on the display screen 5a of the liquid crystal display device 5, for example, that BB or RB winning can be realized. Here, BB and RB are collectively referred to as “bonus” hereinafter. A medal slot 22 is provided on the right side of the liquid crystal display device 5, and a 1-BET switch 11, a 2-BET switch 12, and a maximum BET switch 13 are provided on the left side of the liquid crystal display device 5. The 1-BET switch 11 bets one of the credited medals on the game by a single pressing operation, and the 2-BET switch 12 displays the credited medals by a single pressing operation. Two of them are bet on the game, and the maximum BET switch 13 bets the maximum number of medals that can be bet on one game. By operating these BET switches, a predetermined pay line is activated as described above.

  A C / P switch 14 is provided on the left side of the front portion of the pedestal 10 to switch the credit / payout of medals acquired by the player in the game by a push button operation. By switching the C / P switch 14, medals are paid out from the medal payout opening 15 at the lower front, and the paid-out medals are stored in the medal receiving portion 16. On the right side of the C / P switch 14, the reel is rotated by a player's operation (ie, “start operation”), and a start lever 6 for starting the display of the variation of the symbols in the display windows 4L, 4C, 4R. Is rotatably attached within a predetermined angle range. Three stop buttons 7L, 7C, and 7R for stopping the rotation of the three reels 3L, 3C, and 3R are provided at the center of the front surface of the pedestal 10 and below the liquid crystal display device 5, respectively. Yes. Speakers 21 </ b> L and 21 </ b> R are provided on the left and right above the medal receiving portion 16.

[Reel design row]
FIG. 2 shows a symbol row in which 21 types of symbols represented on the reels 3L, 3C, 3R are arranged. Each symbol is assigned a code number “01” to “21” and stored (stored) in a ROM 32 (see FIG. 9), which will be described later, as a data table. On each of the reels 3L, 3C, 3R, a headband is wound around seven Chinese numerals “7” (design 91), “Don-chan” (design 92), “HANABI” (design 93), “three scales” "Dama" (symbol 94), "capital letter (symbol 95)" and "cherry" (symbol 96) in which capital letters are drawn, and "fan (replay)" (symbol 97) in which a fan is drawn. The configured symbol sequence is shown. Each reel 3L, 3C, 3R is rotationally driven so that the symbol row moves in the direction of the arrow in FIG.

[Winning symbol combination]
FIG. 3 shows the winning combinations and the number of payouts corresponding to winning symbol combinations in each gaming state.

  The gaming state of the present embodiment includes “general gaming state”, “BB internal winning state”, “RB internal winning state”, “BB general gaming state”, and “RB gaming state”. These “five types” of game states are basically distinguished by the types of winning combinations that may be won internally and the types of bonuses that can be achieved. The characteristics of each gaming state, that is, the type of winning combination in each gaming state, its probability, and the stop control of the reels 3L, 3C, 3R in each gaming state (such as the types of winning combinations that may win) This will be described with reference to FIGS. Further, the transition between the game states is performed at the start of the game in the next unit game (before the determination of the internal winning combination), for example, in the process of FIG. In the “BB internal winning state” and “RB internal winning state”, the player can realize the winning of BB and RB by performing a so-called “push”. That is, in the “BB internal winning state” and the “RB internal winning state”, the success or failure of the bonus is determined based on the operation mode (stop operation timing) of the stop buttons 7L, 7C, 7R, and the reel stop control mode. Therefore, the so-called “kicking control” that does not establish the bonus winning is not performed. In the present embodiment, after the bonus is won internally, the bonus is held as an internal winning combination until the bonus is won (generally referred to as “carryover”).

  Here, a gaming state that is generated when the BB winning is established and is configured by the “BB general gaming state” and the “RB gaming state” is hereinafter collectively referred to as “BB gaming state”. In addition, “BB internal winning state” and “RB internal winning state” are states in which a bonus has been won internally (bonus is internally won). State. The “bonus internal winning state” includes a state where a bonus is carried over (a state in which a hit request flag described later is “20 (H)” or “10 (H)”).

  Here, the “hit request flag” indicates the situation of a certain game (whether or not a bonus has been carried over, the type of bonus carried over, etc.), and can be a trigger for the transition of the gaming state in the next game. It is a flag (information). Specifically, when the “hit request flag” is “20 (H)” in a certain game, the gaming state in the next game is “BB internal winning state”. Further, when the “hit request flag” is “10 (H)” in a certain game, the gaming state in the next game is “RB internal winning state”. When the “hit request flag” is “00 (H)” in a certain game, the gaming state in the next game is “general gaming state” or the like.

  As shown in FIG. 3, the BB winning is established by arranging “7-7-7” or “Don-chan-Don-chan-Don-chan” along the active line in the BB internal winning state. After the BB winning is established, the gaming state becomes the BB general gaming state.

  The RB winning is established by arranging "HANABI-HANABI-HANABI" along the active line in the RB internal winning state, or arranging "Folders-Folders-Folders" in the BB general gaming state. The establishment of RB winning in the BB general gaming state is generally referred to as “JAC IN”. After the RB winning is established, the gaming state becomes the RB gaming state.

  The re-game winning is established by arranging “Folders-Folders-Folders” in the general game state and the bonus internal winning state. In the general gaming state, the bonus internal winning state, and the BB general gaming state, it is possible to realize the winning of “cherry small part”, “three shakudama small part”, and “capital small part”. The number of payouts is as shown in the figure.

  The winning combination of winnings is established by arranging “Folders-Folders-Folders” in the RB gaming state. When the number of winning winnings of the bonus becomes “8”, the gaming state changes. Here, a game in an RB gaming state in which a winning combination of an accessory may be established is generally referred to as a “JAC game”.

[Probability lottery table]
Next, referring to FIG. 4, there is shown a probability lottery table used when determining the internal winning combination in the general gaming state when the BET number is “3”.

  In the probability lottery table shown in FIG. 4, when the random value extracted from the range of “0” to “16383” is a value within the range of “0” to “255”, the internal winning combination is “cherry small combination” Is determined. Further, when the random value is a value within the range of “256” to “1720”, the internal winning combination is determined to be “three shakudama small combination”. Furthermore, when the random value is a value within the range of “1721” to “1912”, the internal winning combination is determined as “capital small combination”. Furthermore, when the random value is a value within the range of “1913” to “4157”, the internal winning combination is determined to be a replay. Furthermore, the internal winning combination is determined to be RB when the random number value is in the range of “4158” to “4182”. Furthermore, when the random value is a value within the range of “4183” to “4220”, the internal winning combination is determined to be BB. Furthermore, when the random value is a value within the range of “4221” to “16383”, the internal winning combination is determined to be lost. The probability that BB is determined as an internal winning combination is “38/16384”, that is, about “1 / 431.2”. Further, the probability that RB is determined as an internal winning combination is “25/16384”, that is, about “1 / 655.4”.

  Next, with reference to FIG. 5, a method for determining an internal winning combination and a procedure of an illegal act (so-called “solenoid got action”) that does not use the above-described radio wave or the like will be described. FIG. 5 is an explanatory diagram showing the correspondence between the numerical value range of the random value and the internal winning combination when the probability lottery table of FIG. 4 is used. In FIG. 5, random values are assigned to the horizontal axis, and internal winning combinations corresponding to the random values are assigned. Further, FIG. 5 shows the correspondence between the numerical value range of the random number value and the internal winning combination in the upper stage, and shows an example when an illegal act is performed in the lower stage.

Referring to the upper part of FIG. 5, the numerical value range of the random number generated by the random number generator 36 (FIG. 9) is an integer from “0” to “16383” (a numerical value using a ^14- bit random number counter (2 ¹⁴ )). is there. The random value is generated by incrementing “1”, for example, every about 224 microseconds [μs]. As a specific example, if the random value generated this time is “12345”, the random value “12346” is generated after about 224 microseconds. When the upper limit value (“16383”) drawn on the right end is reached, a random value “0” is generated after about 224 microseconds. In other words, the cycle in which the numerical value range of the random value makes one round is the product of approximately 224 microseconds, which is a cycle for generating a single random value, and “16384”, which is the number of numerical ranges that the random value can take, 3.67 seconds.

  The generated random number value is extracted (sampled) when a start operation (variation start operation) of the start lever 6 is performed. That is, the same random number value is extracted when the start operation is performed every 3.67 seconds, which is a cycle in which the numerical range of the random number value goes around.

  Further, the internal winning combination corresponding to the random value is continuously assigned within the numerical value range of the random value. For example, as described above, when the internal winning combination is determined as “cherry small combination”, the random value is assigned to a value in the range of “0” to “255”. Similarly for the other internal winning combinations, the internal winning combinations corresponding to the random number values are continuously assigned in the numerical value range of the random number values. In addition, the internal winning combination that the random number value can take is “Cherry's small part”, “Triple of small shank”, “Capital small part”, replay, RB, BB, None (losing) It has become. As described above, the random value generated about every 224 microseconds is extracted when the start operation of the start lever 6 is performed, and the internal winning combination corresponding to the extracted random value is referred to the probability lottery table. Will be determined.

  However, an illegal act (so-called “solenoid got action”) focusing on the internal winning combination determination method configured as described above may be performed. Such an illegal act is to use a device that drives a solenoid at regular intervals, and to fix the start lever 6 so as to push the solenoid according to the drive of the solenoid. It is an act of performing a start operation. The constant period in this apparatus is set so that the random number value coincides with the period of going round the numerical range. For this reason, as shown in the upper part of FIG. 5, if the timing for winning a desired internal winning combination such as BB, RB, etc. is found, the desired internal winning combination such as BB, RB, etc. can be won almost permanently.

  As described above, in the present embodiment, the timing at which the start operation of the start lever 6 is detected (that is, “time of fluctuation start operation”, for example, the time and period from the previous start operation to the current start operation) is calculated. Then, it is determined whether or not the timing is within a predetermined timing (ie, “predetermined timing”, for example, a multiple of a cycle in which a numerical value range of a random value is rounded, or a multiple of approximately 3.67 seconds) As a result, it is detected that BB and RB are continuously elected internally, and even illegal activities that are difficult to find even with a radio wave detector or the like are prevented. Details will be described with reference to FIG.

  In addition, this apparatus has a function of shifting the phase by a desired random number value according to the operation. For example, the phase of the random number can be shifted to the timing increased by 250, 500, 600, 2000. In addition, the random number value can be phase-shifted at a timing decreased by 2000. Of course, after a single operation is completed, it has a function of performing a start operation at a constant cycle after the phase. For this reason, BB and RB can be won as an internal winning combination by the following method.

First, as shown in step 1 in the lower part of FIG. 5, an operation of increasing the extracted random number value by 2000 is performed until a replay wins. As shown in FIG. 2, this re-game is represented by a relatively large number of symbols on the reels 3L, 3C, and 3R, and will be won regardless of the timing of the stop operation. Details will be described with reference to FIG. When a re-game is won, as shown in step 2 in the lower part of FIG. 5, an operation of increasing the extracted random number value by 600 is repeated until a win is won (winning is not established). Then, when a loser wins, as shown in step 3 in the lower part of FIG. 5, an operation of decreasing the extracted random number value by 2000 is performed until a replay wins. Thus, there is a random number value that replay is won (e.g., a random number value shown in Figure 5 the lower part of the code X ₁₎ random number value decreased by 200 pieces of than is extracted. Then, as shown in step 4 in the lower part of FIG. 5, an operation of increasing the extracted random number value by 600 is performed. Note that if the result of the first operation in step 4 is a loss, the operation is repeated from step 1. As a result of performing the operation 4 in the second or more times, when a loss is won, an operation of decreasing the extracted random number value by 2000 is performed as shown in the step 5 in the lower part of FIG. Thus, there is a random number value that replay is won (e.g., a random number value shown in Figure 5 the lower part of the code X ₂₎ random number increased by 200 pieces of than is extracted. Then, as shown in step 6 in the lower part of FIG. 5, an operation of increasing the extracted random number value by 500 is performed. Note that if the result of the first operation in step 6 is a loss, the process is repeated from step 1. In addition, when the loss is won as a result of performing the operation 6 in the process 6 or more times, the operation illustrated in the process 3 in the lower part of FIG. 5 is performed.

  In this way, by repeating the operations from step 1 to step 6, it is possible to find the timing at which BB, RB, etc. are internally won. By performing such a procedure at least several times, the timing for extracting random values corresponding to BB and RB can be found with probability. In this way, when BB and RB are won, an operation that does not shift the random number value is performed. Thus, the start operation is performed at the timing when BB and RB are determined as the internal winning combination. Of course, when BB and RB have been won so far, an operation that does not shift the random number value is performed. In the present embodiment, there is no function to prevent such BB, RB, etc. from finding out the timing of internal winning. However, in the configuration described later, the timing at which such BB, RB, etc. are internally won. It is possible to prevent searching.

[Stop table group]
Next, with reference to FIG. 6, the relationship between the gaming state, the internal winning combination, and the selected stop table group will be described. A stop table group stored in a ROM 32 (see FIG. 9) described later is a set of stop tables. In the stop table, a “stop operation position” and a “stop control position” are shown for each of the reels 3L, 3C, and 3R. The “stop operation position” is a symbol (specifically, a symbol) that is located on the center line 8c when the stop buttons 7L, 7C, and 7R provided corresponding to the reels 3L, 3C, and 3R are operated. The code number of the symbol is located above the center line 8c, and the center thereof is closest to the position of the center line 8c. The “stop control position” represents a code number of a symbol that is stopped and displayed at the position of the center line 8c when the reel on which the stop operation has been performed is stopped. In this embodiment, the so-called “sliding frame number” is set to a maximum of “4 frames”.

  Here, the contents of the selected stop table group can basically change according to the gaming state, the internal winning combination, etc., but in this embodiment, the contents of the table group shown in the stop table group column are as follows. The name is determined based on whether or not there is a possibility of winning a prize and the type of role that has the possibility of winning. For this reason, even if stop table groups having the same name are selected, the stop modes of the reels 3L, 3C, and 3R do not always match.

  When the “no winning winning stop table group” is selected, no winning of any combination is established regardless of the internal winning combination and the gaming state. When the winning table for which winning can be established is selected, the winning combination of the corresponding combination is possible, but it is basically impossible to realize the winning combination of other combinations. For example, when the “3 Shakudama Prize winning possible stop table group” is selected, the winning establishment of “Three Shakudama Minoru” can be realized, but the winning establishment of other roles such as BB can be realized. It is not possible. In addition, when the “re-game winning establishment possible stop table group” is selected, winning establishment of “re-game” can be realized, but winning establishment of other roles cannot be realized.

  Similarly, in the BB general game state and the RB game state, the illustrated stop table group is selected, and stop control of the reels 3L, 3C, 3R is performed.

[Symbol and stop table]
The relationship between the symbol sequence and the stop table will be described with reference to FIGS. FIG. 7 is an example of a “re-game winning establishment possible stop table” used when the symbol sequence shown in FIG. 2 is adopted. On the other hand, FIG. 8 is an example of a “no winning stop table” used when the symbol sequence shown in FIG. 2 is adopted.

  When the symbol sequence shown in FIG. 2 is adopted, the “stop control position” of the left reel 3L is the code number “01”, “04”, “07” in the “regame winning establishment stop table” of FIG. , “12” or “17”. The symbol placed on one of the symbols corresponding to these code numbers is “fan”.

  The “stop control position” of the central reel 3C is any one of the code numbers “03”, “08”, “10”, “14”, or “19”. The symbol placed on one of the symbols corresponding to these code numbers is “fan”.

  Furthermore, the “stop control position” of the right reel 3R is one of the code numbers “05”, “09”, “13”, “17”, or “21”. The symbol placed on one of the symbols corresponding to these code numbers is “fan”.

  As described above, when the symbol sequence shown in FIG. 2 is adopted, if the stop control of each reel 3L, 3C, 3R is performed by the “replay winning establishment possible stop table” shown in FIG. 7, along the top line 8b. “Folding fan-Folding fan-Folding fan” is always lined up. In other words, a re-game is always established.

  On the other hand, when the symbol sequence shown in FIG. 2 is adopted, the “stop control position” of the left reel 3L is the code numbers “01”, “04”, “07” in the “no-winning stop table group” in FIG. , “12” or “17”. The “stop control position” of the central reel 3C is any one of the code numbers “03”, “08”, “10”, “14”, or “19”. The symbol placed on one of the symbols corresponding to these code numbers is “fan”. The symbol placed on one of the symbols corresponding to these code numbers is “fan”. Here, the stop control positions for the stop operation positions of the left reel 3L and the center reel 3C are the same as those shown in FIG.

  Furthermore, the “stop control position” of the right reel 3R is one of the code numbers “04”, “08”, “12”, “16”, or “20”. The symbol corresponding to these code numbers is “fan”.

  As described above, when the symbol sequence shown in FIG. 2 is adopted, if the stop control of the reels 3L, 3C, 3R is performed by the “no-winning stop table group” shown in FIG. 8, the top line 8b, the center line 8c, Even in the bottom line 8d, the cross-up line 8a, and the cross-down line 8e, the winning combination is not always established and the game is lost.

  In this way, by controlling to refer to the stop table group, a winning combination according to the stop operation timing of the stop button and the internal winning combination is won. In the present embodiment, the stop control method for each reel 3L, 3C, 3R is “table control method” (a plurality of stop tables (stops as shown in FIGS. 6 to 8 depending on the gaming state and the internal winning combination). Pattern) and a stop control method for performing stop control based on the stop table). However, the present invention is not limited to this, and other modes may be used. For example, “control control method” The stop control of each reel 3L, 3C, 3R may be performed. This “control control method” means that the position where the reels stop does not depend on the “stop table”, but the symbols of the internal winning combination are aligned as much as possible by sliding a predetermined number of sliding frames (for example, 4 frames). This is the control method to be attempted. For example, when a stop button 7L, 7C, 7R provided corresponding to each reel 3L, 3C, 3R is operated to stop, a combination of symbols corresponding to the internal winning combination is caused by slipping within a predetermined number of sliding symbols. If it can be stopped on the active line, the winning of the internal winning combination can be established. On the other hand, when the stop buttons 7L, 7C, 7R provided corresponding to the reels 3L, 3C, 3R are operated to stop, a combination of symbols corresponding to the internal winning combination is caused by slipping within a predetermined number of sliding frames. If it is impossible to stop on the active line, the reels 3L, 3C, and 3R are stopped by sliding the maximum number of sliding frames, but in this case, the internal winning combination is not established.

[Electric configuration of gaming machine]
FIG. 9 is based on a main control circuit 71 that controls game processing operations in the gaming machine 1, peripheral devices (actuators) that are electrically connected to the main control circuit 71, and control commands transmitted from the main control circuit 71. A circuit configuration including a liquid crystal display device 5 and a sub-control circuit 72 that controls the speakers 21L and 21R is shown.

  The main control circuit 71 includes a microcomputer 30 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 30 includes a CPU 31 as control means for performing control operations according to a preset program, and a ROM 32 and RAM 33 as storage means.

  Connected to the CPU 31 are a clock pulse generator 34 and a frequency divider 35 for generating a reference clock pulse, and a random number generator 36 and a sampling circuit 37 for generating a random number to be sampled.

As described above, the random number generator 36 generates random numbers belonging to a certain numerical range (a numerical range of “0” to “16383” using a ^14- bit random number counter (2 ¹⁴ )). The random number generator 36 generates a random number obtained by incrementing the previously generated numerical value by “1” every time an extremely short time (for example, about 224 microseconds) elapses. The random number generator 36 generates the minimum value “0” after generating the upper limit value (“16383”). That is, the random number generator 36 generates a random number increased by “1” every time an extremely short time elapses, and therefore has a function of generating (extracting) the same random number at a constant period (for example, about 3.67 seconds). Will have. Note that an upper limit value (“16383”) may be generated after the minimum value “0” is generated. Further, the random number generator 36 of the present embodiment is configured with the random number range as “0” to “16383” (2 ¹⁴ ). However, the present invention is not limited to this, and other modes may be used. “0” to “65535” (2 ¹⁶ ) may be used.

  The sampling circuit 37 samples a single random number from the random number generator 36 by receiving a predetermined signal supplied from the CPU 31 at an appropriate timing after the start lever 6 is started. That is, the CPU 31 and the sampling circuit 37 extract a random number from the random number generator 36 for each unit game in accordance with the start operation detected in step S9 of FIG. 10 described later (step S13 of FIG. 11 described later). . An internal winning combination is determined based on the random number sampled in this way and the probability lottery table stored in the ROM 32. That is, the CPU 31 determines the internal winning combination based on the random number extracted in step S13 shown in FIG. 11 described later (step S15 in FIG. 11 described later).

  As a means for random number sampling, random number sampling may be executed in the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, or can be left as a backup for the random number sampling operation. Furthermore, although the present embodiment has a function of extracting a similar random number at a constant period, the present invention is applied because an illegal act may be performed even if the period is not necessarily constant. The same effect can be obtained. Of course, each time a predetermined time elapses, a random number obtained by incrementing the previously generated numerical value by “1” may not be generated.

  The ROM 32 of the microcomputer 30 determines the reel stop mode according to the stop operation of the probability lottery table and stop buttons 7L, 7C, and 7R used for determination of random number sampling performed each time the start lever 6 is started. A stop table group for this purpose, various control commands (commands) to be transmitted to the sub control circuit 72, and the like are stored. These commands include “demo display command”, “game start command”, “all reel stop command”, “notification command”, and the like. The sub control circuit 72 does not input commands, information, or the like to the main control circuit 71, and communication is performed in one direction from the main control circuit 71 to the sub control circuit 72. Various information is stored in the RAM 33. For example, a hit request flag, BB stock number information, RB stock number information, and the like are stored.

  In the circuit of FIG. 9, the main actuators whose operation is controlled by a control signal from the microcomputer 30 are a BET lamp (1-BET lamp 9a, 2-BET lamp 9b, maximum BET lamp 9c), and an information display section. 18, a hopper 40 (including a payout drive unit) as a game value giving means for storing medals and paying out a predetermined number of medals according to a command from the hopper drive circuit 41, and rotating reels 3L, 3C, 3R There are stepping motors 49L, 49C, 49R to be driven, and a communication interface (hereinafter referred to as “communication I / F” and also referred to as “communication I / F” in FIG. 9) 52.

  Further, a motor driving circuit 39 for driving and controlling the stepping motors 49L, 49C and 49R, a hopper driving circuit 41 for driving and controlling the hopper 40, and a BET lamp (1-BET lamp 9a, 2-BET lamp 9b, maximum BET lamp 9c) are provided. A lamp driving circuit 45 that controls driving and a display unit driving circuit 48 that controls driving of various display units are connected to the output unit of the CPU 31. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control command includes a start switch 6S, a 1-BET switch 11, a 2-BET switch 12, a maximum BET switch 13, There are a C / P switch 14, a medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51.

  The start switch 6S detects a start operation of the start lever 6. The medal sensor 22S detects medals inserted into the medal insertion slot 22. The reel stop signal circuit 46 generates a stop signal in response to a stop operation of each stop button 7L, 7C, 7R. The reel position detection circuit 50 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 51 generates a signal for detecting completion of the medal payout when the count value of the medal detection unit 40S (the number of medals paid out from the hopper 40) reaches the designated number data.

  The communication I / F 52 communicates with a hall computer (not shown) installed in a game hall (so-called “hall”). The hall computer has a control circuit (for example, CPU, ROM, RAM, etc.) for controlling the hall computer in accordance with a program. For example, the start operation supplied from the gaming machine 1 via the communication I / F 52 You may comprise so that the alerting | reporting process which alert | reports that this timing is a predetermined timing may be performed. In other words, the gaming machine 1 transmits fraud information (information indicating that the timing of the start operation is a predetermined timing) to other computers via a communication line. Action information transmission means is provided. Further, when the fraud information is transmitted to the other computer (for example, hall computer) by the fraud information transmitting means, the other computer notifies the fraud information (for example, the fraudulent behavior). A fraud information notifying means for displaying an image indicating that the act has been performed or notifying the sound of the fraudulent act being performed). In other words, the hall computer includes notifying means for notifying that the timing of the start operation (for example, the time and period from the previous start operation to the current start operation) is a predetermined timing. Of course, a notification image to that effect may be displayed on the liquid crystal display device 5 in the gaming machine 1, or a notification sound to that effect may be generated from the speakers 21L and 21R in the gaming machine 1. That is, the gaming machine 1 may include a notification unit that notifies that the start operation timing is a predetermined timing. As a result, when it is determined that the timing of the start operation of the start lever 6 is a predetermined timing, an illegal act is notified, and the possibility of preventing the illegal act can be increased, and the fairness can be further increased. Games can be provided. The communication I / F 52 is configured to be directly connected to the CPU 31 in the main control circuit 71. However, the communication I / F 52 is not limited to this and may be in another mode. For example, the communication I / F 52 is connected to the sub control circuit 72. In accordance with a predetermined signal supplied from the main control circuit 71, an illegal act can be notified to another computer such as a hall computer.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. From the reels 3L, 3C, 3R, reset pulses are obtained every rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. The count value of the drive pulse counted in the RAM 33 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 33 stores the count value corresponding to the rotational position within the range of one rotation for each of the reels 3L, 3C, 3R.

  A symbol table is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R as described above with symbols drawn on the outer peripheral surface of the reel. In this symbol table, a code number that is sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R with reference to the rotation position where the reset pulse is generated, and a corresponding code number are provided. A symbol code indicating the displayed symbol is associated with the symbol.

  Furthermore, a winning symbol combination table is stored in the ROM 32. In this winning symbol combination table, a winning symbol combination, a winning medal payout number, and a winning determination code representing the winning are associated with each other. The above winning symbol combination table is referred to when the left reel 3L, the center reel 3C, and the right reel 3R are controlled to stop and when a winning confirmation is made after all reels are stopped.

  When the internal winning is made by the lottery process (probability lottery process) based on the random number sampling, the CPU 31 sends an operation signal sent from the reel stop signal circuit 46 at the timing when the player stops the stop buttons 7L, 7C, 7R, Based on the selected “stop table”, a signal for stopping the reels 3L, 3C, 3R is sent to the motor drive circuit 39.

  If the stop mode indicates that the winning combination of the winning combination is established, the CPU 31 supplies a payout command signal to the hopper driving circuit 41 and pays out a predetermined number of medals from the hopper 40. At that time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 40, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 31. As a result, the CPU 31 stops driving the hopper 40 via the hopper drive circuit 41 and ends the “medal payout process”.

[Game machine operation]
Next, the control operation of the CPU 31 of the main control circuit 71 will be described with reference to the flowcharts shown in FIGS. 10 to 12 are main routines (main processing) in the gaming machine 1. FIG. 13 is a subroutine called in step S51 in FIG.

  First, the CPU 31 performs initialization at the start of the game (step S1). Specifically, initialization of recorded contents of the RAM 33, initialization of communication data, and the like are performed. Subsequently, the predetermined recorded contents of the RAM 33 at the end of the game are erased (step S2). Specifically, the data in the writable area of the RAM 33 used for the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 33, the start address of the sequence program of the next game is specified, etc. I do.

  Next, the CPU 31 determines whether or not “30 seconds” have elapsed since the end of the previous game, that is, after all the reels 3L, 3C, 3R stopped (step S3). If this determination is “YES”, a “demo display command” requesting display of “demo image” is transmitted to the sub-control circuit 72 (step S4). If the determination is “NO”, the process proceeds to step S5.

  In step S5, the CPU 31 determines whether or not there is a request for automatic medal insertion, that is, whether or not a replay has been won in the previous game. If this determination is “YES”, medals for the insertion request are automatically inserted (step S6), and the process proceeds to step S8. If the determination in step S5 is “NO”, it is determined whether or not there is an input from either the medal sensor 22S or the BET switches 11 to 13 (step S7). If this determination is “YES”, the process proceeds to step S8, and if “NO”, the process proceeds to step S3. In step S <b> 8, the CPU 31 transmits a “BET command” indicating that the operation of the BET switches 11 to 13 or the operation of inserting medals has been performed to the sub control circuit 72.

  Subsequently, it is determined whether or not there is an input from the start switch 6S based on the start operation of the start lever 6 (step S9). If this determination is “YES”, the CPU 31 proceeds to step S51. That is, a start operation for starting a unit game in this process is detected. On the other hand, if this determination is “NO”, step S9 is repeated.

  In step S51, the CPU 31 executes a fraud detection process. This fraud detection process will be described later in detail. If this process ends, the process moves to step S10.

  In step S10, the CPU 31 determines whether or not “4.1 seconds” have elapsed since the previous game started. If this determination is “YES”, the process proceeds to step S12, and if “NO”, the process proceeds to step S11. In step S11, a “game start waiting time digestion process” is performed. Specifically, a process of invalidating the input based on the start operation of starting the game of the player is performed from the start of the previous game until “4.1 seconds” elapses. In step S12, a reel rotation process is performed, and the process proceeds to step S13 in FIG. That is, when the symbol is stopped and displayed in this process, the symbol necessary for the game is variably displayed according to the start operation detected in step S9.

  In step S13 of FIG. 11, the CPU 31 extracts a random number for lottery, that is, extracts a random number for each unit game in accordance with the start operation detected in step S9. If this process ends, the process moves to step S14.

  A timer for monitoring one game is set (step S14). The random numbers extracted in the process of step S13 are used in the probability lottery process described later. The one-game monitoring timer in the process of step S14 includes an automatic stop timer for automatically stopping the reel regardless of the stop operation of the stop button of the player.

  Next, the CPU 31 performs a probability lottery process (step S15). This probability lottery process (internal lottery process) uses a probability lottery table (see FIG. 4) recorded in the ROM 32 according to the gaming state. Then, it is determined to which random number range the random value extracted in step S13 belongs, and an internal winning combination (establishment flag) is determined. That is, the internal winning combination is determined based on the random number extracted in step S13.

  Next, the CPU 31 determines a stop table group by lottery based on the gaming state, winning combination, etc. (step S16), and proceeds to step S17. In step S17, a “game start command” including information such as “game state” and “winning combination” is transmitted to the sub-control circuit 72, and the process proceeds to step S18.

  In step S <b> 18, the CPU 31 determines whether or not the stop button is “ON”. Specifically, it is determined whether or not any of the stop buttons 7L, 7C, and 7R has been stopped. If this determination is “YES”, the process proceeds to step S20, and if “NO”, the process proceeds to step S19. In step S19, it is determined whether or not the value of the automatic stop timer is “0”. If this determination is “YES”, the process proceeds to step S20, and if “NO”, the process proceeds to step S18.

  In step S20, the CPU 31 performs a sliding frame number determination process. Specifically, a stop table is selected from the determined (selected) stop table group, and the number of sliding symbols is determined based on the selected stop table, stop operation position, and stop control position. Subsequently, the reel corresponding to the stop button for which the stop operation has been performed is rotated by the number of sliding frames, and then stopped (step S21). Subsequently, a “reel stop command” including information on a reel that is subject to stop control (reel corresponding to the stop button that has been stopped) is transmitted to the sub-control circuit 72 (step S22), and the process proceeds to step S23. In step S23, it is determined whether or not all reels are stopped (step S23). If this determination is “YES”, the process proceeds to step S24 in FIG. 12, and if “NO”, the process proceeds to step S18. In other words, after the elapse of a predetermined time, or in response to the player's stop operation, the symbol stop display based on the internal winning combination determined in step S15 is performed. In addition, in this embodiment, although it comprised so that the stop display of a symbol might be performed automatically after a fixed time progress or according to a player's stop operation, it may be another aspect, for example, The stop buttons 7L, 7C, 7R, etc. may not be provided, and the symbol stop display may be automatically performed after a predetermined time. Of course, the symbol stop display may be performed in accordance with the player's stop operation, and the symbol stop display may not be automatically performed after a predetermined time has elapsed.

  In step S24 of FIG. 12, the CPU 31 performs a winning search (step S24). The winning search is to set a winning flag for identifying a winning combination (winning winning combination) based on the pattern stop mode of the display windows 4L, 4C, 4R. Specifically, a winning combination is identified based on a code number of symbols arranged along the center line 8c and a winning determination table. Subsequently, it is determined whether or not the winning flag is normal (step S25). If this determination is “NO”, an illegal error is displayed (step S26). In this case, the game is canceled. If the determination in step S25 is “YES”, a medal credit or payout is performed according to the gaming state (step S27). That is, a game medium is provided based on the stopped symbol. Subsequently, a winning command including information on the winning combination (winning winning combination) is transmitted to the sub-control circuit 72 (step S28).

  Next, the CPU 31 determines whether or not the current gaming state is the “BB general gaming state” or the “RB gaming state” (step S29). When this determination is “NO” (when the gaming state is not “BB general gaming state” or “RB gaming state”), the process proceeds to step S33, and when “YES”, the process proceeds to step S30. In step S30, a bonus “game number check process” is performed. In this “game number check process”, the number of times that the “RB gaming state” has occurred, the number of games in the “BB general gaming state”, the number of winnings in the “RB gaming state”, and the number of games in the “RB gaming state” are checked. At the same time, the game state is shifted (set) between the “BB general game state” and the “RB game state”.

  Next, it is determined whether or not the bonus is over (step S31). Specifically, after the BB wins, the number of wins is 8 or the number of games is 12 in the third “RB gaming state”, or the number of games is 30 in the “BB general gaming state”. It is determined whether or not there is. In addition, after the RB wins by arranging “HANABI-HANABI-HANABI” along the active line in the “general gaming state”, the number of winnings is 8 times or the number of games is 12 times in the “RB gaming state”. It is determined whether or not. If the determination in step S31 is “YES”, the RAM 33 at the end of the BB gaming state is cleared (step S32), and the process proceeds to step S2 in FIG. If the determination in step S31 is “NO”, the process moves to step S2 in FIG.

  If the determination in step S29 is “NO”, a BB / RB winning check process is performed (step S33). In this process, it is determined whether or not BB or RB winning has been established, and the bonus flag corresponding to the bonus for which winning has been established is set to “off”. After this processing, the process proceeds to step S2 in FIG.

[Injustice detection processing]
Next, the control operation of the CPU 31 of the main control circuit 71 will be described with reference to the flowchart shown in FIG. 13 regarding the fraud detection process called in step S51 of FIG.

  First, the CPU 31 calculates the start operation timing, and temporarily stores (temporarily stores) the calculated start operation timing (step S61). As a specific example, when the CPU 31 detects that a start operation has been performed in step S9 executed before this processing, the CPU 31 reads a numerical value from a timer that is reset and sequentially updated in the previous unit game, The data is stored in a predetermined area of the RAM 33. Then, the timer is reset. Thus, the time after the start operation in the previous unit game, that is, the start operation timing is calculated. In other words, the timing of the start operation detected by the determination (processing) in step S9 is calculated and temporarily stored.

  Next, the CPU 31 compares the calculated start operation timing with a predetermined timing set in advance (step S62). As a result of the comparison, the calculated start operation timing is set at a predetermined timing. It is determined whether or not (step S63). In these processes, the CPU 31 reads from the RAM 33 the timing of the start operation calculated in step S61 and temporarily stored. The CPU 31 reads a predetermined timing preset (stored) in the ROM 32. The predetermined timing here is a reference value used as a reference for timing (for example, about 3.67 seconds, which is a cycle in which the numerical value range of the random number value makes a round), and an error value extremely smaller than the reference value (for example, about 45 This indicates a timing range calculated from an arbitrary numerical value (0.01 seconds corresponding to a random number of minutes). The CPU 31 calculates a value obtained by adding the reference value by the error value as an upper limit value, and a value obtained by subtracting the reference value by the error value as a lower limit value. Then, a product of the calculated upper limit value and an arbitrary numerical value is calculated, and a product of the lower limit value and the arbitrary numerical value is calculated. This arbitrary numerical value is an integer increasing by “1”, and the increase starts from “1”.

  A specific example is given. The CPU 31 substitutes “1” as an arbitrary numerical value, and calculates a product of the upper limit value and “1” and a product of the lower limit value and “1”. If the CPU 31 determines that the calculated lower limit value is greater than the start operation timing, the CPU 31 determines that the start operation timing is not a predetermined timing, and proceeds to step S65. That is, even if the calculation and comparison of the predetermined timing are further performed, there is no possibility that the timing of the start operation becomes the predetermined timing, so the processing is moved to step S65. On the other hand, when the CPU 31 determines that the calculated lower limit value is not equal to or higher than the start operation timing, the CPU 31 determines whether the start operation timing is equal to or lower than the upper limit value and equal to or higher than the lower limit value. When it is determined that the start operation timing is equal to or lower than the upper limit value and equal to or higher than the lower limit value, the start operation timing is determined to be a predetermined timing, and the process proceeds to step S64. On the other hand, if it is not determined that the timing of the start operation is less than or equal to the upper limit value and greater than or equal to the lower limit value, “1” is added to the arbitrary numerical value, and the arbitrary numerical value is set to “2”. Repeat the calculation process and the comparison process.

  When the CPU 31 executes such a process, the calculated start operation timing is compared with a predetermined timing set in advance, and the calculated start operation timing is a predetermined timing set in advance. It will be judged whether or not. That is, the timing of the start operation detected in step S9 is calculated, and it is determined whether or not the calculated timing of the start operation is a predetermined timing. In other words, when the calculated start operation timing is a predetermined multiple of a predetermined period including an error, it is determined that the predetermined timing is reached.

  In the present embodiment, when the calculated start operation timing is a predetermined multiple of a predetermined cycle including an error (for example, a cycle corresponding to one round of the random number range of the random number value), However, the present invention is not limited to this, and other modes may be used. For example, the calculated timing of the start operation includes a predetermined period that does not include an error (for example, a random number value). If it is a predetermined multiple of a cycle corresponding to one round of the random number range, etc., there is no problem even if it is determined to be the predetermined timing.

  In step S64, the CPU 31 increments the number counter by “1”. The number counter is positioned in a predetermined area of the RAM 33 and has a function of storing the number of times that the start operation timing is determined to be a predetermined timing. Of course, since the number of times is stored by the CPU 31, the CPU 31 also has a function of storing the number of times that the start operation timing is determined to be a predetermined timing. If this process ends, the process moves to step S66. On the other hand, in step S65, the CPU 31 initializes the number counter. For example, the CPU 31 stores “0” in the number counter. If this process ends, the process moves to step S66. That is, when it is not continuously determined that the timing of the start operation is the predetermined timing, the number counter is initialized. In other words, the number counter CPU 31 in the present embodiment has a function of storing the number of consecutive times determined to be the start operation timing being a predetermined timing.

  In step S66, the CPU 31 determines whether the number counter is equal to or greater than a predetermined value. The CPU 31 reads a numerical value from the number counter stored in the RAM 33 by the process of step S64 or step S65, and determines whether or not it is a predetermined value (for example, three times) or more. As a result of the determination, if it is determined that the value is equal to or greater than the predetermined value, the fraud information is transmitted to the host computer via the communication I / F 52 (step S67). That is, based on the determination result of step S63, notification that the timing of the start operation is a predetermined timing is performed. In other words, if it is determined continuously over a predetermined number of unit games that the timing of the start operation is a predetermined timing, it is determined that an illegal act has been performed, and the timing of the start operation is the predetermined timing. Notify that there is.

  Thus, since it is determined whether or not the timing of the start operation is a predetermined timing, when it is determined that the timing of the start operation is the predetermined timing, specifically, the probability is frequently It is possible to increase the possibility of detecting an illegal act such as a winning combination that is difficult to win and a bonus being frequently selected as an internal winning combination, and to provide a fair game. Further, since the notification that the start operation timing is a predetermined timing is made based on the determined result, when it is determined that the start operation timing is the predetermined timing, specifically, In addition, it is possible to increase the possibility of preventing fraudulent acts by notifying fraudulent acts such as probabilities that are difficult to win frequently and bonuses being frequently selected as internal winners. Games can be provided.

  In this embodiment, when it is determined continuously over a predetermined number of unit games that the timing of the start operation is a predetermined timing, it is determined that an illegal act has been performed, and the timing of the start operation However, the present invention is not limited to this, and other modes may be used. For example, when the start operation is performed at a predetermined timing, a predetermined number of unit games are provided. Even if it is determined discontinuously, it may be determined that an illegal act has been performed, that is, when it is determined in a predetermined number of unit games that the timing of the start operation is a predetermined timing It may be determined that an illegal act has been performed. In addition, the predetermined number of times in the present embodiment may be one time or a plurality of times. Furthermore, for example, as a result of determination over a predetermined number of determinations, it may be configured to determine whether or not the number of times that the start operation timing is determined to be a predetermined timing is greater than or equal to a predetermined number.

  On the other hand, if the CPU 31 does not determine that the numerical value stored in the number counter is greater than or equal to the predetermined value, the CPU 31 ends the present subroutine and proceeds to step S10 in FIG.

  Although the embodiment has been described above, the present invention is not limited to this.

  For example, the above-described error value is set to 0.01 seconds corresponding to, for example, about 45 random numbers, and the predetermined timing is calculated, and it is determined whether the start operation timing is the predetermined timing. However, the present invention is not limited to this, and may be another mode. In particular, the error value is set to about 0.15 seconds corresponding to, for example, about 675 random numbers, the predetermined timing is calculated, and it is configured to determine whether or not the timing of the start operation is the predetermined timing. Thus, it is possible to increase the possibility of detecting the search for BB, RB, etc., so that BB, RB, etc. cannot be easily found. Further, in such a configuration, when it is determined whether or not the numerical value stored in the above-described number counter is greater than or equal to a predetermined value, the predetermined value may be set larger than in the above-described embodiment. preferable. As a result, even when an illegal act is not performed, it is possible to reduce the possibility of erroneously determining that an illegal act has been performed.

  For example, you may comprise so that it may have a function separately. As a specific example, random numbers to be extracted are stored in a storage medium, and a plurality of random numbers stored over a plurality of unit games are compared. You may comprise so that it may determine with having been performed. In this case, for example, after the processing of step S13 in FIG. 11 described above is completed, the random number itself extracted in step S13 is stored in a storage medium such as the RAM 33, compared, and determined. Further, for example, the random number to be extracted and the probability lottery table at the time of the extraction may be configured to be stored in the storage medium, that is, the internal winning combination may be stored in the storage medium. A plurality of internal winning combinations stored over a plurality of unit games may be compared, and if the same internal winning combination continues, it may be configured to determine that an illegal act has been performed. Also in this case, for example, after the process of step S13 in FIG. 11 described above is completed, the internal winning combination based on the random number extracted in step S13 is stored in a storage medium such as a RAM, compared, and determined. Constitute.

  In the present embodiment, as shown in FIG. 10, the process of step S51 is configured to be executed after step S9. However, the present invention is not limited to this. For example, the process of step S51 is performed before step S13 of FIG. Further, it may be configured to execute step S51 after step S13 in FIG. In this case, it is determined whether an illegal act has been performed immediately before or after extracting the random number, and the timing for extracting the random number can be accurately detected. Further, the cheating detection process shown in FIG. 13 may be used as an interrupt process to generate an interrupt to the main flowchart (FIGS. 10 to 12) and perform the cheating detection process at a predetermined timing. In this case, the operation of the start lever 6 can be detected at any time, and an illegal start operation can be detected without regard to the progress state of the game. For example, even when the symbol is displayed in a variable manner, when the start operation of the start lever 6 is performed, it is determined (determined) whether or not the timing of the start operation is a predetermined timing. The operation can be detected regardless of the progress of the game. Further, in the case of such a configuration, the timing at which the fraud detection process as the interrupt process is executed is arbitrary. For example, after the RAM is cleared at the end of the game as in step S2 shown in FIG. The execution of the cheating detection process may be started, and the cheating detection process may be executed at a predetermined timing. Furthermore, in the present embodiment, the main control circuit 71 is configured to execute the fraud detection process. However, the present invention is not limited to this. For example, the fraud detection process described above may be performed. The sub control circuit 72 may be configured to be executed. In this case, the sub control circuit 72 performs various processes based on a predetermined signal supplied from the main control circuit 71 to the sub control circuit 72. It may be configured to execute. In such a configuration, it is preferable that the predetermined signal is derived from, for example, operation of the start lever 6 or extraction of random numbers.

  Further, in the present embodiment, when the above-described fraudulent activity is detected, the fraudulent activity information indicating that the fraudulent activity has been detected is transmitted to the hall computer via the communication I / F 52. Not only this but another mode may be sufficient. For example, a fraud information storage unit that stores fraud information indicating that a fraudulent act has been performed in a storage medium such as an EPROM or a flash ROM provided in the gaming machine 1 when a fraudulent act is detected. The gaming machine 1 may be provided. Of course, any storage medium may be used, but a non-volatile storage medium is preferable. The storage medium is stored in another computer different from the gaming machine 1 (for example, a hall computer, a terminal device such as a mobile phone connected to the hall computer via a communication line, preferably a portable terminal device). You may comprise. In addition, for example, the gaming machine 1 may be provided with a fraudulent information display means for displaying fraudulent information indicating that an illegal act has been performed when a fraudulent act is detected. Further, for example, the gaming machine 1 may be provided with a fraudulent sound generating means for generating a fraudulent sound indicating that a fraudulent act has been performed when a fraudulent act is detected. Furthermore, for example, the gaming machine 1 may be provided with an inoperable control means for giving an error in the gaming machine 1 and controlling the gaming machine 1 itself to an inoperable state. Furthermore, for example, the gaming machine 1 may include a random number update unit that updates a random number and a random number update delay unit that randomly delays the update timing of the random number when an illegal act is detected. Furthermore, for example, when an illegal act is detected, the gaming machine 1 may be provided with an illegal act time storage means for storing the time when the illegal act was started and the time when the illegal act was terminated. Furthermore, for example, when the gaming machine 1 is provided with a photographing means for photographing a player's image and a photographing control means for causing the photographing means to photograph the player's image, when an illegal act is detected. The photographing control unit may have a function of photographing a player's image. Furthermore, for example, identification information reading means for reading from a storage medium storing the identification information of the player or from the human body of the player, and player identification information for storing the identification information of the player read by the identification information reading means The gaming machine 1 may be provided with storage means. Further, for example, the above-described means may be combined, and of course, the above-described means may not be provided. The various processes executed by the above-described means may be configured to be executed at an arbitrary timing when an illegal action is performed, that is, when it is determined that the timing of the start operation is a predetermined timing. For example, you may comprise so that it may replace with step S67 of FIG.

  In the above-described embodiment, for example, when a predetermined small role (for example, capital letters) wins, even if a bonus such as RT (replay time. BB, RB, etc.) is won internally, Is a unit game period in which the bonus is won internally, and the bonus stock can be released (controlling the transition to the bonus internal winning state). The present invention may be applied to a so-called “stock machine”. This RT may be released even when a predetermined number of unit games have been consumed, so that a bonus can be released. In addition, RT is controlled on the condition that a bonus game such as BB, RB, etc. is completed in a state where a bonus internal winning in the general gaming state or a state in which the bonus is won is cumulatively stored. However, the present invention is not limited to this. In such a stock machine, in a state where bonuses are won internally and stocked, a predetermined small role (for example, capital letters) desired by the player is won and illegal actions are performed in a procedure to release the bonus ( For example, when a solenoid goto action is performed, it may be detected that a predetermined small combination is won internally.

  For example, the present invention may be applied to a gaming machine having an AT (assist time) function (so-called “AT machine”). The AT function is a function for winning a predetermined combination when a player performs a stop operation in a predetermined stop operation mode by notifying (assisting) the predetermined stop operation mode. Thus, for example, the small role to be assisted is, for example, a 15-piece role, and the winning mode is “red 7” or “blue 7” for the left reel 3L, “red bell” for the middle reel 3C and the right reel 3R. Or “blue bell”. In addition, among the games in which the AT function is continued, for example, in the last unit game, selection of a color such as “red 7-red bell-red bell” or “blue 7-blue bell-blue bell” is used as a start operation. Accordingly, the gaming machine may be configured such that the AT function is successfully continued when the selected color matches the color of the symbol that is stopped and displayed in the final unit game. . In such a continuation condition for continuing the AT function, in order to continue the AT function, when an illegal act (for example, solenoid goth act) is performed such that the selected color can be recognized by the player, it is selected. It may be detected that the selected color (predetermined combination) is winning internally.
