Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to an improved security related to setting change.

  In a gaming machine such as a slot machine, a player can enjoy a game by inserting a predetermined number of medals and game media such as a game ball into the gaming machine. The game media necessary for the game can be borrowed at a game media rental machine or the like provided in the game hall, and the game can be started by putting it into the game media slot of a desired game machine.

  The slot machine basically pays out medals as prizes when the symbols are arranged, but whether or not the symbols are arranged depends on the result of a lottery by an internal computer. Various prizes, such as big bonuses, regular bonuses, and small roles, also follow the results of internal computer lottery. The content of the lottery process can be changed within a predetermined range (hereinafter, “setting change”), and the setting operation is performed by the store in a hall where a gaming machine is installed.

  To change the setting, open the door of the gaming machine, turn on the setting key switch provided on the power supply unit, turn on the power switch from off, turn on the setting changeable state, press the setting change switch, etc. This is performed according to a predetermined operation procedure. For example, one of the set values 1 to 6 is selected by this operation procedure. These set values correspond to different lottery processes, and the jackpot probability also changes according to the set value.

  In this way, since the probability of jackpot changes according to the setting change, there is a case where an illegal act is attempted in which the setting change is abused to try to make a profit for itself. There are techniques described in the following patent documents as techniques for dealing with such illegal acts.

JP, 2004-201796, A Setting change about internal operation is prevented from performing improperly. Setting key switch and setting switch for changing the setting relating to internal operation, and control for changing the setting according to a predetermined procedure when the setting key switch is settable and the setting switch is operated When the setting key switch is in a settable state and the setting switch is operated, a predetermined hard key switch is confirmed, and the state is saved when the setting is changed last time. The setting is changed according to a predetermined procedure when it matches the set state, and the current hard key switch state is stored. When the two do not match, an error notification is made without changing the setting. JP, 2005-177139, A As a result of initialization after setting change, since a game machine performs operation peculiar after initialization, a player may be able to perceive the presence or absence of a setting change. The present invention provides a gaming machine capable of preventing a player from knowing whether or not a setting has been changed without performing a specific operation after the setting has been changed. A storage unit that stores setting information related to an internal operation, and in a gaming machine in which the setting information of the storage unit is changed when the setting information is requested to be changed, after the change of the setting information, The control unit automatically starts game processing without receiving an operation, and then automatically stops the game. When the game is executed, the gaming machine returns to a normal state. The fairness of the game is maintained by surely detecting the goto action. When the payout rate is selected, the types of the selected first to sixth setting tables are written in the sub-base selection history storage unit. When the game is started, referring to the types of the first to sixth setting tables written in the selection history storage unit, whether or not the first to sixth setting tables used in the winning combination lottery have been changed. Determine. If the types of the first to sixth setting tables written in the selection history storage unit are different from the types of the first to sixth setting tables used in the winning combination lottery, the game process is interrupted. JP, 2006-239190, A The act which changes a lottery table illegally is prevented. After the lottery table is set to be used in the winning determination, the CPU identifies whether or not the set lottery table matches the lottery table set last time. If they do not match, the CPU invalidates the operation of the first to third stop buttons. When the start lever is operated after betting medals in the normal gaming state, rotation of all reels is started and timing is started. When the timer measures a predetermined time, all the reels are stopped and controlled by the CPU and the reel drive controller. When all the reels are stopped, the symbols are stopped and displayed on the activated pay line in a combination indicating a loss.

  A small part of the players performed a dishonest act (so-called goto act). For example, there has been a person who illegally changes the setting of a gaming machine to one that is advantageous to him by making the setting change illegally. In order to prevent such an illegal act, a key is provided on the door of the gaming machine so that it cannot be easily opened and closed, and a key is required to make the setting changeable. It was. However, it seems that the setting was changed by using a stolen key. Unauthorized settings could be changed with the key. As described above, in the conventional gaming machine, anyone can easily change the setting by following a predetermined setting changing procedure. This has the problem that security against fraud is low, and it is easy to suffer from fraud.

There exists a technique of patent document 1 in what solved this. However, anyone can change the setting as long as the setting of the hard key switch according to Patent Document 1 can be known. Since there are few states that the hard key switch can take (on and off), there is a relatively high probability that the setting can be changed by chance without knowing the setting of the hard key switch. The technique described in Patent Document 1 cannot completely prevent unauthorized setting changes.
Patent Documents 2 to 4 do not prevent unauthorized setting changes themselves.

  Accordingly, an object of the present invention is to provide a gaming machine that can prevent unauthorized setting changes.

The present invention performs a plurality of spinning cylinders each displaying a plurality of symbols, an internal lottery based on a game operation by the player, and stop control of the plurality of spinning cylinders according to the result of the internal lottery, A game control unit that performs a winning determination based on a combination of the symbols of the plurality of cylinders stopped by the stop control and performs a payout control of the game medium according to the winning, and a setting related to the internal lottery according to a predetermined procedure The game control unit automatically stops the rotation of the plurality of spinning cylinders when a predetermined time has elapsed from the start of the rotation of the plurality of spinning cylinders. In the gaming machine to let
A storage unit for storing permission information for changing the setting;
When the game control unit automatically stops at least one rotation of the plurality of spinning cylinders, the game control unit stores permission information for changing the setting in the storage unit,
The setting change processing unit changes the setting when the setting change permission information is stored in the storage unit.

The game control unit may delete the setting change permission information stored in the storage unit when receiving a game operation by the player.
Further, the game control unit automatically stops at least one rotation of the plurality of spinning cylinders, or automatically stops at a timing before a predetermined time from the time of automatic stop. Alternatively, an automatic stop notice signal may be transmitted.

  According to the present invention, since it is possible to change the setting only when the rotating cylinder is automatically stopped, the unnatural act of not performing any operation between the rotation start of the rotating cylinder and the automatic stop is illegal. Force the person to be forced, and therefore fraudulent acts are easily revealed. In addition, it is possible to grasp in advance the possibility that the hall clerk will change the setting.

FIG. 6 is a functional block diagram of the slot machine according to the embodiment of the invention.
In FIG. 6, reference numerals 200 and 201 denote a main board and a sub board, each of which contains a CPU, ROM and RAM (not shown). The main board 200 performs medal insertion detection, medal payout, reel rotation stop control, lottery processing, and the like. The sub-board 201 performs processing such as effect display. Reference numeral 202 denotes an operation unit including switches such as a start switch 134, a stop switch 140, and a bet switch without reference numerals. Reference numeral 203 denotes a reel unit (see FIGS. 4 and 5) 203 composed of three rotating reels. An effect display unit 204 includes a game display unit 131, internal illumination of a reel, a liquid crystal display device, a speaker, and the like. The effect display unit 204 notifies the winning combination and the pressing order. A power supply unit 205 supplies power to each unit. 121 is a hopper device for paying out stored medals one by one to a payout opening 135 provided on the front surface of the front door 130.

  The main board 200 is used to perform an internal lottery (internal operation) in response to the player's operation, and to perform 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. In the ROM of the main board 200, for example, a plurality of lottery tables (not shown) respectively corresponding to the setting values 1 to 6 are stored, and lottery processing is performed using the lottery tables corresponding to the setting values set by the setting change. Is done. The set value is for selecting one of a plurality of tables prepared in advance.

  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.

  A gaming machine basically pays out medals when symbols are arranged, but whether or not symbols are arranged depends on the result of a lottery by an internal computer. Also, various prizes such as a big bonus (BB), regular bonus (RB), and small role follow the result of the lottery by the internal computer. The lottery process can be set within a predetermined range (the probability of winning can be increased or decreased), and the setting operation is performed by the store in a hall where a gaming machine is installed. A normal slot machine is preliminarily provided with a plurality of lottery tables (for example, six) having different lottery probabilities such as BB, RB, and small roles. In the slot machine lottery, one of the plurality of lottery tables is set, and the winning / losing determination by lottery is made based on the set lottery table. Changing the setting relating to which of a plurality of lottery tables is used is referred to as setting change.

  In addition, the ROM of the main board 200 stores the lottery table in addition to the game process procedure executed in the slot machine as a sequence program. The lottery table is divided to divide random numbers extracted by a random number generator (not shown) into respective winning modes, and random numbers extracted from a predetermined range of numerical values generated by the random number generating unit The data to be partitioned into is stored. That is, the lottery table has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator. For example, a range of 0 to a certain number is divided into a plurality, one division (area) is excluded, and the other division (area) is set as winning 1, winning 2,. The extracted random number data is checked against each of the data classified for each winning mode in the entire area corresponding to the random number generated from the random number generator, and the winning corresponding to the winning mode to which the random number data belongs is selected. Is determined. For example, it is determined to which category (area) of the lottery table the extracted random number value belongs, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to an out-of-range category (region) in the winning determination table 5, it is determined as “out”. For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out. Various winnings occur with the probability according to the data setting of such a lottery table and the stop control of the symbol is performed, so it is not extremely influenced by the skill of the player, for example, within the business hours of the day The total medal payment rate in Japan is maintained almost constant.

  As described above, the main board 200 performs processing such as internal lottery, reel rotation / stop, and medal payout. In addition to this, the count of medals inserted into the medal selector 1 and the hopper device Processing such as determination of the amount of medals stored in 121 (a hopper medal empty error occurs when there are no medals) is performed. Of the processes performed by the main board 200, the game control unit 200a is shown in FIG. 6 for the sake of convenience as the process of performing the former internal lottery, reel rotation / stop, and medal payout. Actually, the game control unit 200a is realized by the CPU executing a program stored in the ROM of the main board 200 (this is the same for the setting change processing unit 200c described later).

  The game control unit 200a performs a process of automatically stopping the rotation of the reel when a predetermined time has elapsed even when there is no operation by the player, as one of the controls related to the rotation / stop of the reel. .

  The main board 200 further includes a setting change enable / disable state storage unit 200b for storing information (hereinafter referred to as “flag”) for determining whether setting change is possible / impossible (permitted / not permitted), and a setting key switch. When 2054 is turned on, a transition is made to a state for changing the setting relating to the internal lottery, and the setting is changed in accordance with a predetermined procedure such as pressing the setting change / reset switch 2055 a predetermined number of times. A setting change processing unit 200c to be performed.

  When the rotation of the reel is automatically stopped, the game control unit 200a stores a flag that enables the setting change in the setting changeable / impossible state storage unit 200b. In other words, the game control unit 200a also functions as a determination unit that determines whether or not the reel rotation has been automatically stopped. Note that the flag that enables the setting change is reset at a predetermined timing (for example, when a medal insertion is detected).

  The setting change processing unit 200c changes the setting when a flag permitting the setting change is stored in the setting change enable / disable state storage unit 200b.

  The gaming machine according to the embodiment of the present invention enables setting change only when the reels are automatically stopped by the main board 200 (game control unit 200a). When a certain period of time elapses after the reel is rotated, the reel automatically stops even if the player does not press the stop switch 140. According to the embodiment of the invention, the setting can be changed only after the automatic stop. Thereby, fraudulent acts can be prevented. It usually takes several minutes from the start of reel rotation to its automatic stop, and it is usually not considered that no operation is performed during that time. Such an action becomes difficult for the fraudulent acts to be caught in the eyes of the surrounding human beings and attract attention. It also makes it easier for hall attendants to find fraud.

  Next, the operation of the gaming machine according to the embodiment of the invention will be described with reference to the flowcharts of FIGS.

S10: When the processing such as the initial setting is completed after the power is turned on, the gaming machine enters a game ready state.

S11: It is determined whether or not a medal has been inserted. When a predetermined number of medals are inserted (YES in S11), the game control unit 200a starts a game process. A bet switch may be pressed instead of inserting a medal.

S12: When a medal is inserted, the gaming machine is set in a state where setting change is impossible. Specifically, the flag of the setting changeable / impossible state storage unit 200b is reset (more precisely, when the flag of the setting changeable / impossible state storage unit 200b is set (= 1), Is reset (= 0) and left as it is when it is reset).
By setting the gaming machine in a state in which the setting change is impossible in S12, it is possible to prevent the state in which the setting change set in S18 described later can be changed for a long time. In S12, it can be said that the effective period in which the setting can be changed is determined.

S13: It is determined whether or not the start switch 134 has been pressed.

S14: When the start switch 134 is pressed, rotation of the reels 40a to 40c is started.

S15: The stop switch 140 determines whether all of the three reels 40a to 40c are stopped. When all the three reels 40a to 40c are stopped by the stop switch 140 (YES in S15), the process returns to S10.

S16: When there is an unstopped reel (NO in S15), it is determined whether or not the state has passed for a predetermined time (for example, 3 minutes). If the predetermined time has not elapsed, the process returns to S15. When the predetermined time has elapsed (YES in S16), the process proceeds to an automatic reel stop process (S17).

S17: The reel that is still rotating at the present time is automatically stopped.

S18: When the reels are automatically stopped, the gaming machine is set so that the setting can be changed. Specifically, the flag of the setting changeable / impossible state storage unit 200b is set (= 1).

  By the processes in S10 to S18, the setting change is permitted after the reels are automatically stopped and before the medal is inserted. Since it is essential to automatically stop the reel in order to change the setting, it is difficult to make an illegal setting change.

  Note that the process S12 of FIG. 7 is executed between the medal insertion determination process S11 and the start switch press determination process S13, but the present invention is not limited to this. S12 may be arranged anywhere as long as it is between S10 and S14. To be precise, after a certain time has elapsed since entering the state of S10 (in this case, the setting can be changed only before the certain time has elapsed since entering the state of S10) to below S14 It can be arranged until the stop switch is pushed in the conditional branch S15.

Although S12 determines the effective period of the state in which the setting can be changed, in the gaming machine according to the embodiment of the present invention, the state in which the setting can be changed should not be continued. Configuration changes should be made as soon as it becomes possible. Since the setting change is performed in a state where the game is not being executed, the gaming machine should be in a state in which the setting change cannot be performed when the game is started. Therefore, the game control unit 200a can change the setting when receiving a game operation (inserting a medal, pressing a bet switch, pressing a start switch 134, starting an internal lottery, starting reel rotation, etc.) by the player / It is desirable to reset (erase) the flag stored in the impossible state storage unit 200b. By doing so, it is possible to make it difficult to perform fraud, and it is possible to cope with a case where a normal player happens to automatically stop the reel.
Note that the fact that a predetermined time has elapsed from the setting of the flag in S18 may be added to the reset condition of the setting change permission flag in S12.

  The automatic stop condition includes exceeding a predetermined threshold (time), but other conditions may be used. Anything can be used as long as it has a certain interval, and the condition for automatic stop is not limited.

  In the processing of S14 to S17, the setting changeable state may be made even with automatic stop of only one reel, or the setting changeable state may be made only when all three reels are automatically stopped.

  FIG. 8 is a flowchart of the setting change process.

S20: When the setting key switch 2054 is turned on, the setting change processing unit 200c checks the flag of the setting changeable / impossible state storage unit 200b.

S21: When the flag is set (YES in S21), a setting change process is executed (S22). If not (NO in S21), the process is terminated without changing the setting. Since the setting change process is publicly known, the description thereof is omitted.

  According to the embodiment of the present invention, since the setting can be changed only when the reel is automatically stopped, an unnatural act of not performing any operation between the reel rotation start and the automatic stop is performed. Forces fraudsters to make it easier to reveal fraudulent activities. In addition, it is possible to grasp in advance the possibility that the hall clerk will change the setting. Therefore, according to the embodiment of the present invention, illegal acts can be prevented.

  In addition, when the player receives a gaming operation, the setting of the gaming machine is made incapable of changing the setting, so that it is possible to make it difficult for the cheating to be performed, and when the normal player happens to automatically stop the reel. Inconvenience will not occur.

  In addition, a signal indicating that the reels are automatically stopped or a signal for notifying them to the hall computer that is provided separately from the gaming machines and manages a plurality of gaming machines (a signal indicating that the possibility of automatic stopping has increased) May be transmitted.

  In game halls (halls) where game machines such as slot machines are installed, hall computers that can exchange information by connecting to these game machines are installed in the game halls, and signals related to games in the game machines are information management devices In many cases, a game system is constructed that collects and stores input signals. For example, in the case of a slot machine, the signals relating to the game are, for example, a signal indicating that the mode has shifted to the BB (big bonus) mode or the RB (regular bonus) mode, a signal indicating that a medal has been inserted, and a signal indicating that a medal has been paid out. Etc. These signals are transmitted to the information management apparatus via a circuit board called an external concentration terminal board provided in the slot machine. As a result, the information management device can manage the status and information of each slot machine based on the signal output from the external concentrated terminal board.

  In addition to a known signal sent from the gaming machine to the hall computer, a signal indicating the automatic stop of the reel of the gaming machine according to the embodiment of the invention or a signal for notifying it is sent to which gaming machine in the hall computer. Can be managed whether it is in a setting changeable state or is in that state. This is effective in preventing fraud.

  FIG. 9 shows a transmission flowchart of the reel automatic stop signal and / or automatic stop notice signal according to the embodiment of the invention. This figure corresponds to a part of the game process of FIG. 7, and the display of S10 to S14 of FIG. 7 is omitted. Hereinafter, a description will be given of the difference from FIG.

S15a: It is determined whether it is the transmission timing of the automatic stop notice signal. The automatic stop notice signal is after the reel has been rotated and when the possibility of automatic stop is increased without being stopped by the stop switch (stop button) 140 (specifically, the timing of automatic stop) Sent when) is approached. For example, when it is set to automatically stop in 3 minutes from the start of reel rotation, an automatic stop notice signal is transmitted when 2 minutes have passed. The game control unit 200a includes, for example, a timer for measuring the transmission timing of the automatic stop notice signal in addition to the timer for determining the automatic stop of the reel.

S15b: When the automatic stop warning signal is transmitted (YES in S15a), the reel automatic stop warning signal is transmitted to the outside. In the flowchart of FIG. 9, the automatic stop notice signal is repeatedly transmitted until the reels are automatically stopped, but may be transmitted only once.

S16: When there is an unstopped reel (NO in S15), it is determined whether or not the state has passed for a predetermined time (for example, 3 minutes). If the predetermined time has not elapsed, the process returns to S15. When the predetermined time has elapsed (YES in S16), the process proceeds to an automatic reel stop process (S17).

S17: The reel that is still rotating at the present time is automatically stopped.
S17a: An automatic reel stop signal is transmitted to the outside, and the process proceeds to a process (S18) for setting the gaming machine in a setting changeable state.

  In FIG. 9, both the automatic stop signal and the automatic stop notice signal of the reel are transmitted to the outside, but the present invention is not limited to this, and only one of them may be transmitted.

  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.
