Description

  The present invention relates to a gaming machine such as a slot machine, a fraud detection method in a gaming machine, and a program for causing a computer to execute the method.

  Pachinko machines such as pachinko machines and slot machines that are installed and used in game halls such as pachinko parlors are given a certain value to game media such as pachinko balls and medals, and the game media acquired by playing games It can be exchanged for various prizes. The gaming machine is provided with various drive devices such as a lamp device and a sound generation device that are operated based on the supply of the game medium, and a control circuit device corresponding to control these drive devices inside the housing. Therefore, when the player plays a game, the game is filled with interest by appropriately operating them. Further, in recent years, a variable symbol display device such as a reel display device or a liquid crystal image display device that can display predetermined identification information (symbol) in a variable manner is built in and stopped after changing the identification information when a predetermined condition is satisfied. The mainstream is to operate the variable symbol display device so that it can be displayed. These devices are controlled by a control circuit device.

  A control circuit device disposed in a recent gaming machine is generally one in which a CPU (central processing unit) provided on a board performs electronic control according to a control program. The control program is stored as data in an IC chip mounted on a substrate such as a mask ROM (read only memory), and the CPU sequentially reads and executes the control program data from the IC chip according to the gaming state. Control is done by doing.

The gaming machine installed in the game hall is managed so that the control program is not tampered with. The main board is stored in a storage case, and the storage case is assembled to a predetermined member of the main body frame. In addition, consideration is given so that the ROM that stores the control program is not illegally replaced. Furthermore, a seal seal is stuck on the ROM so that it cannot be easily removed from the mounted substrate.
Moreover, there exist some which were described in patent document 1 and 2 as an electrical sealing means.

Japanese Patent Application Laid-Open No. 7-289712 “Game Device” A connection monitoring function for monitoring a connection between a game control board and another control board is provided to detect unauthorized removal. The connection information input circuit outputs a signal representing the connection state between the game control board and the relay board to the board monitoring circuit. The board monitoring circuit stops the control operation function when a signal indicating an abnormal connection state is input from the connection information input circuit. Japanese Patent Application Laid-Open No. 11-326435 “Abnormality Monitoring Device” Detects opening of a circuit storage box and insertion / removal of a connector. The sealing wire is wound around the storage box or between the male part and the female part of the connector. When the container box is opened or the connector is pulled out, the sealing wire must be cut. This cutting of the sealing wire is detected by a detection circuit.

  By the way, there is a so-called “driving machine”. This is an electronic device in which the connector of the wire harness that connects the board to the board is removed inside the gaming machine and is connected to the connector instead of the board. The driving machine is provided in place of the switch board, for example, in a wire harness that connects the switch board provided with the start switch and the main board. The driving machine generates operation signals (medal insertion signal, start switch signal, stop button signal, medal payout signal, etc.). For example, regardless of whether or not the start switch is operated, a signal corresponding to pressing the start switch is electrically generated and input to the main board to execute a predetermined game process. If a driving machine is used, a game can be automatically and repeatedly executed without human operation. Such an act is called “driving” and is an illegal act. The driving machine, for example, wins a big bonus with a low probability of occurrence by repeatedly executing the game, and induces a profit to a specific player by holding a winning flag stored in the memory at that time It seems to be used for applications. The driving is often performed as one of the customers on the hall side, and the driving machine seems to be installed by the hall clerk.

  “Driving” is to accumulate a bonus in a stock machine capable of accumulating a so-called bonus, and in a normal gaming machine that is not a stock machine, a game is played until a bonus is won. Internal information such as the number of bonuses for stock machines and the winning status of bonuses is stored in a storage unit (register).

  An object of the present invention is to provide a gaming machine capable of detecting that a game has been performed, a method of detecting fraud in the gaming machine, and a program.

The present invention includes a predetermined switch and a processing unit including a winning lottery means for performing lottery based on a signal from the predetermined switch, and wins a predetermined winning combination in the lottery and corresponds to the predetermined winning combination In a gaming machine that gives a predetermined profit to a player by winning,

A reel unit 203 includes three rotating reels. Reference numeral 204 denotes an effect display unit including internal lighting of the reel of the game display unit 131, electrical decoration, a liquid crystal display device, a speaker, and the like. The effect display unit 204 notifies the winning combination and the pressing order. 121 is a hopper device for paying out stored medals one by one to a payout port 135 provided on the front surface of the door 130.

  Although the operation unit 202 includes several switches as described above, only the start switch 134 directly related to the embodiment of the invention is clearly shown in FIG.

  The main board 200 is for performing an internal lottery based on the output signal of the start switch 134, and processing such as reel rotation / stop and medal payout. The main board 200 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The main board 200 includes a winning lottery means 200a that performs a lottery based on a signal from the start switch 134 and performs a winning determination based on the result of the lottery. As a winning combination by lottery, a winning combination that does not carry over and the flag will disappear if the winning game is not won, such as a small role, and even if you do not win in the winning game, such as a bonus, will win in the next game or later There is a carry-over flag that is carried over without the flag disappearing.

  The winning lottery means 200a includes a register R that stores a winning flag of a winning with a low occurrence probability such as a big bonus.

  The main board 200 includes a winning history storage unit 200b for storing the number of times (winning number) of winning in a winning combination (big bonus) determined in advance by the winning lottery means 200a. The winning lottery means 200a wins a predetermined winning combination, and a winning combination is made when the symbols corresponding to the predetermined winning combination are arranged, but the winning history storage unit 200b stores the number of winning.

  The sub-board 201 is for receiving a command signal from the main board 200 and notifying the result of the internal lottery and performing various effects. The sub-board 201 includes a CPU that performs a control operation in accordance with a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results.

  The ROM of the main board 200 stores the game processing procedure executed by the gaming machine as a sequence program, and stores a winning determination table, a symbol table, a winning symbol combination table, and the like. ing. The winning determination table is divided so as to divide the random value extracted by the random number acquisition unit (random number generator and random number extractor) into each winning mode, and from among a certain range of numerical values generated by the random number acquisition unit Data for dividing the extracted random value into each winning mode is stored. In other words, the winning determination table has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number acquisition unit. For example, a range of 0 to a certain number is divided into a plurality, one division (region) is excluded, and the other division (region) is set as winning 1, winning 2,.

  As described above, the main board 200 and the sub board 201 are configured around the CPU, and include a ROM, a RAM, an I / O, and the like. Temporary data required when the CPU operates is stored in the RAM. The RAM is a volatile memory, and data is lost in principle when the power is cut off. However, in the gaming machine according to the embodiment of the invention, a backup power source such as a battery is prepared for a part or all of the data. Will not be lost.

FIG. 4 is a process flowchart of the gaming machine according to the embodiment of the invention.
The main board 200 monitors the power-on of the gaming machine, and starts the processing of FIG. 4 immediately after the power-on.

S1: Count the number of lotteries of the winning lottery means 200a after the power is turned on. One lottery is performed when the start switch 134 is turned on once. Actually, the start switch (predetermined switch) 134 is effective on condition that a medal is inserted or a bet switch is used. When the start switch 134 is pressed in the enabled state, a lottery is performed, and a plurality (three) of the reels 203 of the reel unit 203 starts rotating (at the same time, the start switch 134 is disabled). Thereafter, a stop operation (pressing the stop switch 140) is performed for each of the rotating reels, and the symbols of the plurality of stopped rotating reels are arranged in a predetermined combination. When one of the winning combinations is won, a payout is made and one game is finished. .

S2: It is determined whether or not a winning combination (big bonus) determined in advance as a result of the lottery has been won. That is, it is determined whether or not a predetermined winning combination is won and the symbols corresponding to the winning combination are prepared.

S3: When winning a predetermined combination (big bonus), it is determined whether or not it is within a predetermined number of lotteries. When the number of games (the number counted in S1) when winning a predetermined combination (big bonus) exceeds a predetermined number (for example, 10 times) (YES in S3), the processes after S4 are executed. . When that is not right (it is NO at S3), the monitoring process of FIG. 4 is complete | finished.

S4: It is determined whether the number of winnings exceeds a predetermined number. That is, when YES is determined in S3, the number of winnings stored in the winning history storage unit 200b is increased (+1). Then, when the number of winnings exceeds a predetermined number (for example, 10 times), it is determined that the number of winnings exceeds the predetermined number (YES in S4), and the processes after S5 are executed. The number of winnings means the cumulative number of times that a winning combination (big bonus) has been won within a predetermined number of times immediately after the power is turned on (the cumulative number determined as YES in S3). It is probable that a big bonus is often won immediately after the power is turned on. Therefore, if the cumulative number is large, it may be determined that there is an illegal act by a so-called “driving machine”.

  A backup power supply is connected to the winning history storage unit 200b, and the data is retained even when the power is off. Unless the winning history storage unit 200b is reset, the number of winnings stored therein does not return to the initial value (zero). The reset conditions will be described later.

S5: A warning error is notified. An error is notified to the outside through the effect display unit 204 or the like. A message such as “The machine is in use” may be displayed using a liquid crystal display device.

S6: The winning result for a predetermined combination such as a big bonus is invalidated. Here, “invalidate” is, for example, as follows.
(1) The game of the big bonus is invalidated after winning a predetermined combination (such as a big bonus; hereinafter, taking a big bonus as an example). Specifically, it is not providing the profit originally given to the big bonus, such as not playing the game or shifting to the big bonus game.
(2) If there is a big bonus winning flag when winning a big bonus, a big bonus winning flag when winning a bonus, and the big bonus winning flag is to shift to a big bonus game, the big bonus winning flag is invalidated when winning the big bonus To do.
To invalidate (reset) the flag is to clear the contents of the register (storage unit) R. By doing so, it is possible to eliminate the provision of profits by the “driving machine”. Note that a flag indicating that a warning error has been notified is stored in, for example, the winning history storage unit 200b, the flag is checked at the next power-on, and when it is set, S1 in FIG. The result of winning a predetermined combination such as a big bonus may be immediately invalidated without performing the processes of. Note that the process of S6 may be omitted.

  In S4, the number of winnings stored in the winning history storage unit 200b is increased. However, the increase in the number of winnings may be limited to one on the same day. Although the gaming machine may be turned on many times a day, it is not necessary to perform the process of FIG. 4 every time. Therefore, the processing of FIG. 4 is performed only when the power is turned on at the beginning of the day. Whether or not they are the same day may be determined based on date or day information from a clock device (not shown).

For example, the history storage unit 200b is reset under the following conditions, and the number of winnings is returned to the initial value.
・ S5 in FIG. 4: after warning error notification ・ S6 in FIG. 4: after flag reset

  FIG. 5 is a timing chart for explaining the operation of the gaming machine according to the embodiment of the invention. Hereinafter, explanation will be added to this figure.

  When the power is turned on at the timing indicated by symbol a, the processing in FIG. 4 is started. In the process of FIG. 4, a range of 1 to 10 is monitored (the number in the second box indicates the number of lotteries).

  If the big bonus (BB) is won in the sixth lottery as indicated by reference symbol b, a history writing signal is generated as indicated by reference symbol c, and the number of winnings in the winning history storage unit 200b is determined from N as indicated by reference symbol d. Increase to N + 1. The history writing signal is displayed for convenience of explanation, and may not actually be present.

  Even after winning the big bonus as shown by the symbol e after the end of the monitoring range, the number of winnings does not increase.

  According to the gaming machine according to the embodiment of the invention, since the error notification is performed based on the number of winnings in the winning history storage unit, it is possible to detect and notify an illegal act using the “driving machine”. In addition, by providing a flag reset, it is possible to prevent a profit from being provided by the “driving machine”.

  In the above description, whether or not the “driving machine” is used is determined based on the number of winnings, but may be determined based on the number of winnings in the winning lottery means.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
