Description

  The present invention relates to a gaming machine that variably displays a symbol on a symbol display device, stops the symbol in a predetermined manner, and generates a predetermined gaming state, and in particular, in a gaming machine having a plurality of special prize states, the design change is possible. The present invention relates to a gaming machine that is easy and suitable for reducing data capacity and processing load.

  As a conventional pachinko machine, for example, when a game ball is won at a start winning opening, a lottery for starting a variable display of a lottery symbol on a symbol display device and causing a special prize state (bonus) is performed. When it is determined that the special prize state is to be generated based on the lottery result, the lottery symbols are stopped in a specific combination after the predetermined time has elapsed, and the special prize state is generated. When the special prize state occurs, the opening / closing of the grand prize opening is controlled with a predetermined opening / closing pattern, and a predetermined number (for example, 15) of prize balls are paid out for each prize winning to the big prize opening.

Further, as a pachinko machine that uses random numbers in the big hit lottery, a technique described in Patent Document 1 is known.
The invention described in Patent Document 1 includes a storage unit that stores a jackpot value belonging to a numerical value range for each numerical value range when a predetermined numerical value range is divided into a plurality of numerical value ranges, and a numerical value range to which a random number value belongs among the numerical value ranges And determining whether or not the jackpot value of the storage unit corresponding to the determined numerical range matches the random value.
JP 2000-109596 A

  By the way, as a conventional pachinko machine, after setting a plurality of special prize states and determining that a special prize state is to be generated, a lottery is performed, and one of a plurality of special prize states is generated based on the lottery result. A pachinko machine to let you know is known. As the type of the special prize state, for example, a so-called normal jackpot that shifts to the normal gaming state after the completion of the special prize state, a gaming state called a probability variation state in which the probability of becoming a special prize state after the completion of the special prize state is higher than normal is generated. There is a promising big hit, a time big win when a game state called a short state occurs when the symbol variation time becomes shorter than usual after the special prize state ends.

  In the case of a pachinko machine having a plurality of special prize states, a combination of stop symbols must be determined for each special prize state. At this time, the combination of stop symbols is determined according to the occurrence probability set for each special prize state. For example, if it is a probable big hit, a combination of odd numbers such as “111”, “333”, and “555” is used, but “777” and other combinations are generated at a ratio of m: n. Is extracted from the stop symbol determination table in which m stop symbol numbers indicating “777” and n stop symbol numbers indicating other combinations are registered, based on the random number value. In order to perform such adjustment of the probability of occurrence for each special prize state, the stop symbol determination table divides records in correspondence with each special prize state. For example, a normal jackpot stop symbol number is registered in the 1st to n1th records, and a probability variable jackpot stop symbol number is registered in the n1 + 1 to n2th records. In the normal jackpot stop symbol determination process, a random number in the numerical range of 1 to n1 is acquired, and a stop symbol number of the rank of the acquired random number value is acquired from the stop symbol determination table. Further, in the stop symbol determination process for probability variation big hit, a random number in the numerical range of n1 + 1 to n2 is acquired, and a stop symbol number of the rank of the acquired random number value is acquired from the stop symbol determination table.

However, in such a configuration, when the occurrence probability of the stop symbol is readjusted for each special prize state, the section of the stop symbol determination table must be changed, and the table can be changed for one special prize state. Since the whole has to be changed, there is a problem that the design change is not easy.
Moreover, in order not to change the whole table, the structure which provides a stop symbol determination table for every special prize state can be considered. However, in this case, since the same random number counter is used, the number of records in each stop symbol determination table must be the same. Moreover, when the number of records is increased, the stop symbol determination table must be adjusted to an integer multiple of the initial number of records so that the occurrence probability at the time of design is not changed. For this reason, the number of records in each stop symbol determination table needs to be the least common multiple of the number of records in each stop symbol determination table, rather than matching the stop symbol determination table having the maximum number of records. Therefore, the problem that the data capacity becomes large is assumed. In addition, since the number of records in the stop symbol determination table increases, there is a problem that the number of determinations increases and the processing load increases.

On the other hand, although invention of patent document 1 is a technique for lottery lottery determination rather than determination of a stop symbol, it aims at reducing the processing load of jackpot determination processing. However, even if the technique of this document is applied to the latter configuration in which a stop symbol determination table is provided for each special prize state, the problem of an increase in data capacity cannot be solved. Moreover, even if it applies to the former structure using one stop symbol determination table, the problem that a design change is not easy cannot be solved.
Therefore, the present invention was made paying attention to such an unsolved problem of the conventional technology, and in a gaming machine having a plurality of special prize states, the design change is easy, and the data capacity and An object of the present invention is to provide a gaming machine suitable for reducing the processing load.

To achieve the above object, the gaming machine according to claim 1, wherein according to the present invention includes: a first drawing means for performing whether lottery to rise to a predetermined gaming state in response to winning to start winning opening, A second lottery means for performing a lottery to determine which of the plurality of gaming states is caused; and a symbol display control means for performing control to display the symbols in a variable manner on the symbol display means in response to a winning at the start winning opening. , Game state generating means for generating any one of the plurality of game states based on the lottery results of the first lottery means and the second lottery means, and the lottery results of the first lottery means and the second lottery means And a stop symbol determining means for determining a stop symbol mode to be displayed when the variable display is stopped, wherein the stop symbol information indicating the stop symbol mode is registered. Decision A table storage unit that stores a table for each gaming state, and a random number acquisition unit that acquires a random number that can take any value in a numerical range including the least common multiple of the number of records in each stop symbol determination table. The stop symbol determination means reads out the stop symbol determination table corresponding to the gaming state determined by the lottery of the second lottery means from the table storage means, the random number value acquired by the random number acquisition means and the first Based on the constant corresponding to the gaming state determined by the lottery of the two lottery means, the ranking information indicating any value in the numerical range including the number of records of the read stop symbol determination table is generated and generated The stop symbol information of the rank indicated by the rank information is read from the read stop symbol determination table, and based on the read stop symbol information. Is adapted to determine the mode of the stop symbols Te, the constant dividing said least common multiple, the number of records of the stop symbol determination table corresponding to the game state determined by the lottery of the second drawing means The stop symbol determining means divides the random value acquired by the random number acquiring means by the constant to generate the rank information .

  With such a configuration, when there is a winning at the start winning opening, the first lottery means is used to make a lottery as to whether or not to cause a predetermined gaming state, and the symbol display control means The variable display control of the symbol is performed. In addition, the second lottery means performs a lottery to determine which of the plurality of gaming states is to be generated, and the random number acquisition means selects any one of the numerical ranges within the range of the least common multiple of the number of records in each stop symbol determination table. A random number that can take these values is acquired.

  Next, the stop symbol determination means reads out the stop symbol determination table corresponding to the gaming state determined by the lottery from the table storage unit, and based on the acquired random number value and the constant corresponding to the gaming state determined by the lottery. Thus, ranking information indicating any value in the numerical range including the number of records in the stop symbol determination table is generated. Then, the stop symbol information of the rank indicated by the generated rank information is read from the stop symbol determination table, the mode of the stop symbol is determined based on the read stop symbol information, and then the symbol is determined in the determined mode. Stops.

Further, any one of a plurality of gaming states is generated based on the lottery result by the gaming state generating means.
Thereby, in order to readjust the occurrence probability of the stop symbol for each gaming state, the configuration of the stop symbol determination table corresponding to the gaming state may be changed. Also, each stop symbol determination table can be configured with the required number of records.
Here, the start winning opening means a hole or a gate provided on the surface of the game board for winning or passing a game ball, for example, a winning opening or an operating gate. Accordingly, winning includes not only winning but also passing.

Then, the stop symbol determining means divides the random value by a constant to generate rank information. The constant is the value obtained by dividing the least common multiple of the number of records in each stop symbol determination table by the number of records in the stop symbol determination table corresponding to the gaming state determined by the lottery. The rank information indicating any value in the numerical range including the number of records in the symbol determination table is generated.
Here, any gaming state may be used, for example, a special prize state that is a gaming state advantageous to the player, or a probability variation state that is a gaming state in which the special prize state is likely to occur. Is mentioned.
The table storage means stores the stop symbol determination table at any time and at any time. The stop symbol determination table may be stored in advance, or the stop symbol determination table may be stored in advance. Without stopping, the stop symbol determination table may be stored by an external input or the like during the operation of the gaming machine.

As described above, by the present invention lever, to readjust the generation probability of the stop symbols in each gaming state, it is sufficient to change the configuration of the stop symbol determination table corresponding to the player state, designed The effect that the change becomes easy is obtained. Further, since each stop symbol determination table can be configured with the required number of records, an effect that the data capacity and the processing load can be reduced is also obtained.

Left sleeve winning opening 124 and right sleeve winning opening 125 are provided.
Below the effect symbol display device 104 is provided a start winning opening 111 that allows a game ball to be always won. When the game ball wins, the start winning port 111 detects the winning of the game ball based on a detection signal of a start winning port switch 131 (not shown) inside the pachinko machine, and the effect symbol display device 104 and the special symbol display device 106 change. Give an opportunity to start displaying. The variation display of the special symbol and the effect symbol is stopped after a predetermined variation time has elapsed, and a lottery result notification and effect are performed.

  On the right side of the start winning opening 111, a special symbol display device 106 is provided that displays the special symbols in two regions while independently varying them. The special symbol display device 106 is, for example, a variable display device such as a liquid crystal display or a CRT display, a 7-segment LED, a dot matrix display device, and the like, and variably displays a special symbol composed of a plurality of numbers, symbols, and the like. In the present embodiment, the special symbol display device 106 is a two-digit 7-segment LED. Here, the case where the stop symbols of the special symbol display device 106 are in a specific combination is referred to as a “special prize state” (big win or small hit), and the “special prize” means that the game state has many prize balls for the player. The point which transfers to the advantageous state which gives predetermined | prescribed game value, such as paying out. Further, the special symbol corresponds to the effect symbol displayed on the effect symbol display device 104.

On the right side of the special symbol display device 106, there is provided a game state display device 109 for notifying the state of the pachinko machine such as during a big hit (during a special prize state) or during a symbol variation time shortening control (so-called short time). The gaming state display device 109 is a display device made up of LEDs, for example, and notifies the gaming state by lighting or flashing.
A normal symbol operation memory indicator lamp 117 is provided below the start winning opening 111. The normal symbol operation memory indicator lamp 117 stores information on each game ball that has passed through the operation gates 113 and 114 during fluctuation of the normal symbol in a holding area for each game ball on the RAM of the main control board. It lights in conjunction and notifies the number of times that the normal symbol can be changed continuously.

Below the normal symbol operation memory indicator lamp 117, a normal symbol display device 108 is provided for displaying the normal symbol consisting of a one-digit number from “0” to “9” while varying it. The normal symbol display device 108 is, for example, a 7 segment LED.
Actuating gates 113 and 114 are provided on both the left and right sides of the normal symbol display device 108 so that the game ball can always pass therethrough. When the game ball passes, the operation gates 113 and 114 detect the passage of the game ball by the detection signal of the internal operation gate switch, and give an opportunity to start the variable display of the normal symbol display device 108.

  Below the normal symbol display device 108, when the symbols displayed in the three areas of the production symbol display device 104 become a big hit symbol under normal conditions, the game is opened in a predetermined pattern. A grand prize opening 115 is provided to allow a ball to be awarded. When the special symbol display device 106 has a specific combination of stop symbols (that is, when it becomes a special prize), the special prize opening 115 is opened / closed on the entire surface of the special prize opening 115 in the subsequent special prize state. The member performs opening and closing operations. During the occurrence of the special prize state, the opening / closing member opens almost horizontally and accepts a large number of game balls. When a game ball wins, the big prize opening 115 counts the number of game balls won by a detection signal of a big prize opening switch 132 (not shown) inside the pachinko machine, and pays out the prize ball when winning. The opening of the special winning opening 115 is continued until a predetermined time (for example, 30 seconds) elapses or a predetermined number of gaming balls (for example, ten predetermined winning prize winning numbers, for example) are won. One opening of the big prize opening 115 is called a round. The round continues from 1R → 2R →... And continues until the maximum round.

  Each of the left and right sides of the grand prize winning hole 115 is provided with a left falling prize winning hole 126 and a right falling prize winning hole 127 that allow a game ball to be always awarded. When the number displayed on the normal symbol display device 108 is in a specific state in a state, a normal electric accessory 112 is provided that is open in a predetermined pattern and allows a game ball to be won. When the game ball wins, the ordinary electric accessory 112 detects the game ball winning by the detection signal of the winning port switch inside the pachinko machine, and gives an opportunity to start the variable display of the special symbol display device 106.

An out port 110 for collecting game balls that have not won any of the above winning ports or the like is provided below the ordinary electric accessory 112 and below the game board surface 102.
Note that, hereinafter, a gaming state in which the probability of entering the special prize state after the completion of the special prize state is higher than normal is referred to as “probability variation state”, and a gaming state other than the special prize state and the probability variation state is referred to as “normal state”.

Next, the configuration of the game control device 200 in the pachinko machine will be described.
FIG. 2 is a block diagram showing a configuration of the game control device 200.
As shown in FIG. 2, the game control device 200 is mainly composed of a main control board 210 (main control unit), an effect control device 150 (effect control unit), and a symbol control device 152 (effect symbol display control unit). Consists of two control units. In order to prevent fraud, etc., each control unit is usually mounted on a separate board for each function, and can be directly or indirectly connected to transmit data to each other or in one direction. The main control board 210 transmits a control command and controls the entire game in accordance with a random number generated internally based on the detection of the game ball by winning at the start winning opening 111, and also displays the special symbol display device 106. Control directly.

The effect control device 150 transmits a control command (second control command) for controlling the symbol control device 152 in accordance with a control command (first control command) transmitted from the main control board 210, and a game Control of blinking of lamps provided in the area and the like and output control of sound output from the speaker of the pachinko machine.
The symbol control device 152 controls the effect symbol display device 104 in accordance with a control command (second control command) transmitted from the effect control device 150.

The main control board 210 includes a CPU 220, a ROM 230, a RAM 240, an input port 250 and an output port 255.
The output port 255 includes a special symbol display output port for outputting to the special symbol display device 106, a normal symbol display output port for outputting to the normal symbol display device 108, and a special symbol operation memory indicator lamp 116. Special symbol operation memory indicator light port for performing output, normal symbol operation memory indicator light port for performing output to the normal symbol operation memory indicator light 117, and command output for the effect control device performing output to the effect control device 150 A prize ball payout that outputs to a prize ball payout control device 156 that performs a payout control of a prize ball to a prize ball payout device (transmitting a first control command such as a design symbol designation command or a variation pattern command) Output port, a special winning port solenoid output port for outputting to the special winning port solenoid 158 for opening and closing the special winning port 115, and an output to the game status display device 109. A gaming state display output port for, consists of an external information output ports 256 Metropolitan for outputting to an external hall computer. The effect symbol designation command (first control command) is a control command for designating a stop symbol of the effect symbol displayed on the effect symbol display device 104, and the variation pattern command (first control command) is an effect. This is a control command for designating the mode of screen fluctuation such as reach, disappointment, special prize, etc. displayed on the symbol display device 104.

  Although not shown, the external information output port 256 includes at least a first signal generation unit that is a first signal generation unit and a second signal generation unit that is a second signal generation unit. The first signal generator generates a signal that is output during the state so that a state such as the jackpot information signal can be identified. The output time varies depending on the state and the like. For example, the second signal generation unit detects a change in a state such as a symbol determination number information signal and generates a signal. Further, since the output time informs the detection, it is output for a preset period.

  The main control board 210 receives detection signals from the start winning port switch 131, the big winning port switch 132, and other various winning port switches 133 via the input port 250 and processes them. The main control board 210 is connected to the special symbol display device 106, the special symbol operation memory indicator lamp 116, the normal symbol display device 108, the normal symbol operation memory indicator light 117, the big prize opening solenoid 158, and the external information output via the output port 255. Control the game state display device 109. Here, “control” is a process of changing the special symbol by, for example, the main control board 210 sending a control signal related to display driving directly from the output port 255 to the special symbol display device 106. For example, it includes sending a signal (command) from the CPU 220 directly without judgment by another CPU or controlling without a time delay (time lag) due to an interrupt or the like. In addition, the main control board 210 transmits an effect control command (first control command such as an effect symbol designation command and a variation pattern command) to the effect control device 150 to control the effect control device 150 by command transmission.

The ROM 230 stores a program for controlling the pachinko machine executed by the main control board 210. The ROM 230 further stores values of various parameters for controlling the pachinko machine including an effect designating command for controlling the effect control device 150 and a variation pattern command.
The RAM 240 temporarily stores input / output data for the main control board 210, data for arithmetic processing, various counters including a random number counter related to the game, and the like, and has a holding memory for storing information of each holding ball. .

The RAM 240 stores a control command to be output in a predetermined area, and when the power is restored from a power failure, the contents of the RAM 240 are restored to the state immediately before the power failure, and the control command to be output from the RAM 240 is output to shut off the power. Return the gaming state to the previous state.
A power supply circuit 212 for supplying power is connected to the main control board 210. When the power supply circuit 212 detects that the voltage of the power supply line supplied to the entire main control board 210 has become equal to or lower than a predetermined voltage value, the power supply circuit 212 sends a power-off detection signal indicating that the power supply is cut off to the CPU 220. Output. When power-off is detected, the power line supplied to the entire main control board 210 is switched to a power line directly connected to the CPU 220 when the power is cut off. Thereby, since power is supplied to the RAM 240 from the power supply line directly connected to the CPU 220, information can be held.

  The effect control device 150 includes a CPU, a ROM, a RAM, an input port, and an output port, like the main control board 210. A control command (first control command such as an effect symbol designation command) transmitted from the main control board 210 is received, and a liquid crystal display control command (second control command) is generated in accordance with the effect symbol designation command. It transmits to the control apparatus 152. The effect control device 150 performs lamp blinking control, which is control of the indicator lamp 153, sound effect output control, which is control of the sound effect output device 155, and the like. In this way, the effect control device 150 is useful for reducing the load on the main control board 210 by performing specialized control related to effects such as liquid crystal display, lamp blinking, and sound effect generation.

  The symbol control device 152 receives the liquid crystal display control command (second control command) transmitted from the effect control device 150, and fluctuates / stops the effect symbol of the effect symbol display device 104 according to the liquid crystal display control command, or It has a function of receiving a notice designation command selected and transmitted by the effect control device 150 and displaying the notice.

Next, the mode of the stop symbol of the special symbol and the effect symbol will be described.
FIG. 3 is a diagram showing an aspect of a special symbol stop symbol.
In the pachinko machine, as shown in FIG. 3, five types of gaming states or winning states of “time saving”, “left odd”, “left even”, “2 rounds”, and “small hit” are defined. Each gaming state is identified by a gaming state number 0-4.

  When the “short time” is generated, the special symbol display device 106 is controlled to stop the non-stochastic variation symbol and the effect symbol display device 104 is controlled to stop the rendering symbol with the non-probability variation symbol. The non-stochastic variation symbol is, for example, a combination of even numbers such as “222”, “444”, and “666” in the effect symbol display device 104. “Short time” is the maximum number of times that the winning prize opening 115 is opened at the time of jackpot, that is, the maximum number of continuations of the round is 15, and no promotion effect is generated during the jackpot. The game state is controlled so as to be in the normal state as well as the variation time of the production symbol) is shortened.

  When the “left odd” is caused, the special symbol display device 106 is controlled to stop the probability variation symbol and the effect symbol display device 104 is controlled to stop the effect symbol with the probability variation symbol. For example, in the effect symbol display device 104, the probability variation symbol is a combination of odd numbers such as “111”, “333”, and “555”. “Strange odd” is the maximum number of times the winning prize opening 115 is opened at the time of the big hit, that is, the maximum number of continuations of the round is fifteen times. In the gaming state after the jackpot is over, the gaming state is controlled so as to be in a probability variation state without reducing the variation time of the symbols (both special symbols and production symbols).

  When the “left even” is caused, the special symbol display device 106 is controlled to stop the probability variation symbol, and when the jackpot is determined, the effect symbol display device 104 is controlled to stop the effect symbol with the non-probability variation symbol. The “left even” is the maximum number of times the winning prize opening 115 is opened at the time of the big hit, that is, the maximum number of continuations of the round is 15, and when the big hit is determined, the effect symbol display device 104 does not notify that the probability variation state is present. In this gaming state, the promotion effect is generated during the jackpot to notify the promotion to the probability variation state, and the gaming state after the jackpot is controlled so as to be in the probability variation state without reducing the symbol variation time. In addition, in the design variation of the effect symbol when the “left even” is generated, the non-probability variation symbol is displayed before the promotion effect, and the probability variation symbol is displayed after the promotion effect. It is to be noted that the effect design is changed, and the special design is not changed. That is, the probability variation symbol is displayed from the time of determination.

  When the “two rounds” are caused, the special symbol display device 106 and the effect symbol display device 104 are caused to stop the two round specific symbols. In “2 rounds”, the maximum number of times the grand prize winning opening 115 at the time of the big hit, that is, the maximum number of continuations of the round is two times. It is a gaming state that is controlled so as to be in a probability varying state without reducing the symbol variation time in the gaming state after the end of the jackpot without producing an effect. In addition, the opening time of the winning prize opening 115 is several ms, which is extremely shorter than the normal big hit time. In this way, since the period of one round is short and the maximum number of continuations of the round is only two times, the chance of winning a prize is less likely to occur for a player than a big hit (15 times) without a special prize state occurring. Unexpectedness can be given as if it suddenly changed to a fluctuating state. In addition, it is easy for game shops to make a balance between the probability of winning and operation.

  When the “small hit” is caused, the symbol is stopped at the small hit symbol. “Small Bonus” means that the winning prize opening 115 is opened twice, that is, the maximum number of rounds at the time of winning is two times. This is a gaming state that is controlled so as to be in a normal state without shortening the symbol variation time. In addition, by making the opening time and the number of opening of the big prize opening 115 the same in “2 rounds” and “small winning”, and also controlling the production to the same content, it is difficult to distinguish the big winning from the small winning, A new game production can be created.

  Promotion effect is effect control performed to notify the player whether or not to shift to the probability variation state, while the symbol that stopped when the jackpot occurred was the normal symbol, while during the jackpot effect The player is notified of the change to the probability variation state through the effect control. In this case, although it is actually a jackpot where the probability fluctuation state has been fixed internally, it seems that it changed (promoted) during the subsequent jackpot processing after first displaying the effect as if it was hit with a normal symbol first. It is something to make. In addition to the case where the promotion effect changes from the normal state to the probability variation state, for example, the promotion effect includes, for example, an increase in the number of round continuations performed at the time of big hit (for example, an increase change from 6 rounds to 15 rounds) Further, the above contents may be combined.

  Further, the promotion effect may be generated for each round during the jackpot processing, or may be generated only for a specific round. Further, control may be performed so that the degree of reliability for promotion differs according to the round that occurs. If it occurs during the first round, the probability of promotion will be higher, and it can be controlled so that the probability decreases as the round progresses and approaches the end of the maximum number of continuations, and vice versa. It can also be controlled. By controlling in this way, it is possible to further give the player an unexpectedness.

Next, the structure of the table stored in the ROM 230 will be described.
The ROM 230 stores a jackpot type determination table 400 used to determine the jackpot type.
FIG. 4 is a diagram illustrating a data structure of the jackpot type determination table 400.

  In the jackpot type determination table 400, as shown in FIG. 4, 100 records are registered. Each record includes a field in which a game state number is registered. A random number that can take any value in the numerical range of “0” to “99” (hereinafter referred to as a jackpot type determination random number) is acquired at the time of starting winning (when the starting winning port switch 131 is detected), and the acquired random number value Are read from the jackpot type determination table 400, and a special prize state specified by the read game state number is generated. For example, when the random value is “97”, a numerical value is acquired from the 97th record. In the example of FIG. 4, since “1” is read from the jackpot type determination table 400, referring to FIG. 3, “left odd” occurs as a special prize state corresponding to the same number in the list of FIG. In other words, the maximum number of continuations of the round at the jackpot is 15 times, the promotion effect during the jackpot is not generated, and the game variation state after the jackpot is in a probability variation state without shortening the symbol variation time.

The ROM 230 further stores a stop symbol determination table 420 used for determining a combination of stop symbols of special symbols for each gaming state.
FIG. 5 is a diagram showing the data structure of the stop symbol determination table 420.
A plurality of records are registered in the stop symbol determination table 420 as shown in FIG. Each record includes a field for registering a stop symbol number indicating a combination of stop symbols. For example, the stop symbol number “7” indicates that the combination of stop symbols of the effect symbol is “777”.

  In each stop symbol determination table 420, records are registered according to the probability of occurrence of a stop symbol set for the corresponding gaming state (winning state). For example, in order to cause “777” and other combinations to occur at a ratio of m: n, m stop symbol numbers of “777” and n other stop symbol numbers are registered. In the stop symbol determination table 420 for “short time”, “left odd”, “left even”, “2 rounds”, and “small hit”, for example, 20, 30, 10, 20, and 20 respectively. Records are registered.

The ROM 230 further stores a divisor table 440 used for generating rank information for reading out the stop symbol number from the stop symbol determination table 420 for each gaming state.
FIG. 6 is a diagram illustrating the data structure of the divisor table 440.
In the divisor table 440, as shown in FIG. 6, one record is registered for each gaming state number. Each record includes a field for registering a game state number and a field for registering a divisor. Least common multiple of the number of records in each stop symbol determination table 420 (In the above example, the number of records in each stop symbol determination table 420 is “20”, “30”, “10”, “20”, “20”. Is a random number that can take any value within the numerical range of “60”) (hereinafter referred to as a stop symbol determination random number) at the time of starting winning (when the starting winning port switch 131 is detected), and the acquired randomness. The ranking information is generated by dividing the numerical value by the divisor corresponding to the gaming state number. For example, since the divisor is “3” for “time reduction”, when the stop symbol determination random number value is divided by “3”, rank information indicating any value in the numerical range of “0” to “19” is generated. Is done. Since the number of records in the stop symbol determination table 420 for “time reduction” is “20”, stop symbol numbers can be read for all records using the generated rank information.

Next, game control processing executed on the main control board 210 will be described.
The CPU 220 is composed of a microprocessing unit or the like, operates based on a game control program that can execute one cycle with a predetermined operation clock (for example, 4 [ms]), and is stored in a predetermined area of the ROM 230. Is started, and the game control process shown in the flowchart of FIG. 7 is executed.

First, the game control process will be described.
FIG. 7 is a flowchart showing the game control process.
When the game control process is executed by the CPU 220, as shown in FIG. 7, first, the process proceeds to step S100.
In step S100, an initialization process of the CPU 220 is executed, the process proceeds to step S102, and an interrupt permission instruction for executing the interrupt process of FIG. Thereby, the interrupt process of FIG. 8 is executed in parallel with the game control process at a predetermined cycle (for example, 2 [ms]).

Next, the process proceeds to step S104, and the production control random numbers related to the production (for example, random numbers used in the reach lottery to determine whether or not to reach, random numbers for determining the type of symbols to be displayed, and notice production random numbers) are updated. The random number update process is executed, and the process proceeds to step S106.
In step S106, it is determined whether or not the interrupt process of FIG. 8 has been executed a predetermined number of times (for example, twice) after the game control process has been executed, and when it is determined that the interrupt process has been executed a predetermined number of times (Yes ) Shifts to step S108, executes jackpot determination processing for determining a jackpot determination and determining a symbol variation pattern, and shifts to step S110.

The process proceeds to step S110, and the electric accessory actuating process for opening the special winning opening 115 in a predetermined pattern is executed, and the process proceeds to step S112 to control the prize ball payout control device 156 to perform a payout operation. A prize-ball payout management process for storing the command in a predetermined area of the RAM 240 is executed, and the process proceeds to step S114.
In step S114, external information output processing for outputting an external information signal related to game control to the hall computer is executed via the external information output port, and the process proceeds to step S116.

  In step S116, a gaming machine inspection signal output process for outputting a gaming machine inspection signal necessary for the inspection of the pachinko machine is executed. In step S116, a gaming machine inspection signal is output, but when installed in a gaming store, the pachinko machine does not include a control unit that receives the gaming machine inspection signal. This is because it is a signal required at the time of inspection in an inspection organization. In some cases, the process of step S116 can be omitted.

  Next, the process proceeds to step S118, and a port output process for outputting the control command stored in the RAM 240 to the effect control device 150 via the effect control device command output port is executed. First, a strobe signal is output to the effect control device 150, and a control command including information indicating a gaming state and information indicating a specific control content in the instructed gaming state is output. As a result, a control command (first control command) is output to the effect control device 150. Also, the control information from the main control board 210 is output as it is to the special symbol display device 106, the big prize opening solenoid 158, the game state display device 109, and the like.

Next, the process proceeds to step S120, where it is determined whether or not a power-off detection signal is input from the power supply circuit 212. When it is determined that the power-off detection signal is input (Yes), the process proceeds to step S122.
In step S122, return information necessary for restoring the contents of the RAM 240 is generated, the generated restoration information is stored in the RAM 240, and a backup process for switching the CPU 220 to the power saving mode is executed. The backup process includes a process for setting a backup flag and a process for performing a checksum.
On the other hand, when it is determined in step S120 that the power-off detection signal is not input (No), and in step S106, it is determined that the interrupt process has not been executed a predetermined number of times after the game control process has been executed (No). In any case, the process proceeds to step S104.

Next, interrupt processing will be described.
FIG. 8 is a flowchart showing the interrupt process.
When the interrupt process is executed by the CPU 220, as shown in FIG. 8, first, the process proceeds to step S150.
In step S150, a random number for controlling a ball that is directly related to the determination of the ball or the like (for example, a random number used for a big hit lottery for determining whether or not to generate a big hit (hereinafter referred to as a big hit random number), a big hit type determination random number, a stop pattern Execute random number update processing to update (determined random number). Further, the effect control random number updated in step S104 is also updated.
Next, the process proceeds to step S152, where a winning switch input process for inputting a detection signal from the start winning opening switch 131 and checking a winning is executed, and a series of processes are terminated and the original process is restored.

Next, the random number update process in step S150 will be described.
FIG. 9 is a flowchart showing random number update processing.
When the random number update process is executed in the CPU 220, as shown in FIG. 9, first, the process proceeds to step S170.
In step S170, an initial value update random number for winning determined random number for updating the initial value of the winning determined random number is set as the winning determined random number, the process proceeds to step S172, the winning determined random number is added, and the process proceeds to step S174. .

In step S174, it is determined whether or not the winning random number has reached a predetermined upper limit value (for example, 498). If it is determined that the predetermined upper limit value has been reached (Yes), the process proceeds to step S176, The initial value update random number for winning determination random number for updating the initial value of the winning determination random number is set as the winning determination random number, and the process proceeds to step S172.
On the other hand, when it is determined in step S174 that the winning random number does not reach the predetermined upper limit (No), the process proceeds to step S172.
Thus, since the initial value changes every time the winning random number makes a round, the winning random number cannot be easily predicted.
Although illustration is omitted, the process of updating the jackpot type determination random number, the stop symbol determination random number and other random numbers for controlling the play is similarly performed in this random number update process.

Next, the winning switch input process in step S122 will be described.
FIG. 10 is a flowchart showing a winning switch input process.
When the winning switch input process is executed in step S122, the process first proceeds to step S200 as shown in FIG.
In step S200, an input port reading process for reading the detection signal from the start winning port switch 131 from a predetermined port of the input port 250 corresponding to the start winning port switch 131 is executed, and the process proceeds to step S202. Based on the processing result, it is determined whether or not a detection signal is input from the start winning a prize opening switch 131. When it is determined that the detection signal is input (Yes), the process proceeds to step S204.

In step S204, it is determined whether or not the number of winning game balls to the start winning opening 111 is “4” or more. When it is determined that the number of winning game balls is less than “4” (No), step S206 is performed. Then, “1” is added to the number of winning game balls, and the process proceeds to step S208.
In step S208, the winning random number, the big hit type determining random number, and the stop symbol determining random number are acquired from the corresponding random number counter, and the process proceeds to step S210. Each is stored in the area, a series of processing is terminated, and the original processing is restored. In step S210, for example, when the number of winning game balls is “1”, each acquired random number value is stored in the first area of the RAM 240 for storing random number values. Similarly, when the number of winning game balls is “2”, each acquired random number value is stored in the second area for storing random number values.
On the other hand, when it is determined in step S204 that the number of winning game balls is “4” or more (Yes), or when it is determined in step S202 that a detection signal is not input from the start winning port switch 131 (No). Also, the series of processing is terminated and the original processing is restored.

Next, the jackpot determination process in step S108 will be described. In addition, description is abbreviate | omitted about the determination process of the normal symbol display apparatus 108. FIG.
FIG. 11 is a flowchart showing the jackpot determination process.
The jackpot determination process sets a single jackpot value in a predetermined numerical range (for example, “0” to “398”) in order to cause a special prize state with a predetermined probability (for example, 1/399), and starts a winning prize. A process for obtaining a winning random number from a random number counter at a winning timing when a game ball wins in the mouth 111 and causing a special prize state when the acquired random number value matches the jackpot value, and is executed in step S108. Then, as shown in FIG. 11, first, the process proceeds to step S300.

In step S300, the effect symbol display device 104 determines whether or not the effect symbol is fluctuating. When it is determined that the effect symbol is not fluctuating (No), the process proceeds to step S302, where the number of winning game balls is “ It is determined whether or not it is 1 ”or more, and when it is determined that the number of winning game balls is“ 1 ”or more (Yes), the process proceeds to step S306.
In step S306, a winning random number is read from a predetermined area of the RAM 240 corresponding to the number of winning game balls, and the process proceeds to step S308 to determine whether or not the read random number value matches the jackpot value. When it is determined that it has been made (Yes), the process proceeds to step S310.

In step S310, a jackpot type determination process for determining a jackpot type is executed. In the jackpot type determination process, the jackpot type determination random number is read from a predetermined area of the RAM 240 corresponding to the number of winning game balls, and the game state number of the rank of the read random number value is read from the jackpot type determination table 400.
Next, the process proceeds to step S312, and a big hit stop symbol determination process for determining a combination of special symbols and production symbols to be stopped at the big hit time (including the small hit time) is executed. The big hit hour variation pattern determination process for determining the variation pattern of the effect symbol that is sometimes displayed in a variable manner is executed, and the process proceeds to step S316.

  In step S316, in the case of a big win or a small win, the number of times of opening and opening time of the big winning opening 115 is set (in the case of gaming state numbers 0 to 2 with reference to FIG. In addition, the opening time of the special winning opening 115 is set to about 30 seconds, and in the case of the game state numbers 3 to 4, the number of times and the opening time corresponding to this are set). In addition, the process for setting the symbol variation time is executed regardless of the hit.

Next, the process proceeds to step S318, and a symbol variation start process is executed in which a control command for starting variation of the effect symbol is stored in a predetermined area of the RAM 240 in the effect symbol display device 104, and the process proceeds to step S320 to receive a prize. “1” is subtracted from the number of game balls, a series of processing is terminated, and the original processing is restored.
On the other hand, when it is determined in step S308 that the read random number value does not match the jackpot value (No), the process proceeds to step S324, and the random value read in step S306 matches the preset jackpot value. If it is determined whether or not they match (No), the process proceeds to step S326. In Steps S308 and S324, the big hit and the small win are determined with one random number. For example, when the winning random number is “7”, it is determined as a big hit, when it is “11”, it is determined as a small hit, and when it is “13”, it is determined as a big hit (only when high probability). As a result, the data capacity can be reduced and the random number update process can be simplified as compared with the case where separate random numbers are provided.

  In step S326, an off-stop symbol determination process for determining a combination of effect symbols to be stopped at the time of loss is executed. This determination does not indicate a specific combination of outliers displayed on the effect symbol display device 104, but is a command that indicates only the result that the winning lottery result is outlier. The designation command is output to the symbol control device 152 via the effect control device 150. The symbol control device 152 determines a combination of symbols to be out of order and displays the contents on the effect symbol display device 104 when an outlier design symbol designation command is input.

Next, the process proceeds to step S328, and a variation pattern determination process at the time of losing is performed to determine a variation pattern of the effect symbol that is variably displayed at the time of deviation, and the process proceeds to step S316.
On the other hand, when it is determined in step S324 that the read random number value matches the small hit value (Yes), the process proceeds to step S330 and the gaming state number is set to “4” indicating “small hit”. Then, the process proceeds to step S312. That is, at the time of determining the small hit, the game state number “4”, which is a fixed value set in advance, is set without reading the big hit type determining random number stored in the predetermined area of the RAM 240 corresponding to the number of winning game balls. . (Type setting process at the time of small hit confirmation)
On the other hand, when it is determined in step S302 that the number of winning game balls is “0” (No) and in step S300, when it is determined that the effect symbol is changing in the effect symbol display device 104 (Yes). In either case, the series of processing is terminated and the original processing is restored.

Next, the stop symbol determination process in step S312 will be described.
FIG. 12 is a flowchart showing the stop symbol determination process.
When the stop symbol determination process is executed in step S312, as shown in FIG. 12, first, the process proceeds to step S400.
In step S400, the stop symbol determination table 420 corresponding to the gaming state number read in step S410 or the gaming state number set in step S330 is read from the ROM 230, the process proceeds to step S402, and the gaming state number read in step S410 or The divisor corresponding to the gaming state number set in step S430 is read from the divisor table 440, and the process proceeds to step S404.

  In step S404, the stop symbol determination random number is read from a predetermined area of the RAM 240 corresponding to the number of winning game balls, the process proceeds to step S406, and the read random number value is divided by the read divisor and read from the divisor table 440. The rank information indicating any value in the numerical range including the number of records in the stop symbol determination table 420 is generated, and the process proceeds to step S408.

In step S408, the stop symbol number of the rank indicated by the generated rank information is read from the read stop symbol determination table 420, the process proceeds to step S410, and the combination of stop symbols of effect symbols is performed based on the read stop symbol number. A designation command (first control command) for designating is stored in a predetermined area of the RAM 240, and the process proceeds to step S412.
In step S412, a probability variation flag and other various flags are set based on the read random number value, a series of processes are terminated, and the process returns to the original process.

  In addition, the combination of the stop symbol of a special symbol is also determined by the same process. However, the special symbol is determined prior to determining the effect symbol. That is, after determining the special symbol, the effect symbol is determined corresponding to this. Therefore, in any case, the combination of stop symbols is determined based on the random number value read in step S404. For special symbols, command information for designating a combination of stop symbols of special symbols is stored in a predetermined area of the RAM 240. Thereby, in the port output process of step S118, the command information is directly transmitted to the special symbol display device 106 via the output port 255.

Next, the operation of this embodiment will be described.
First, when the power is turned on to the pachinko machine, the main control board 210 executes a game control process and enters a game-ready state. A player can play a game by loading the rented game ball into a pachinko machine and operating the launch handle to launch the game ball onto the game board surface 102.

  In a game-ready state, when a game ball launched on the game board surface 102 wins the start winning opening 111, a detection signal is output by the starting winning opening switch 131. In the main control board 210, when a detection signal is input from the start winning port switch 131, at almost the same timing, the winning decision random number, the big hit type determining random number and the stop symbol determining random number are obtained from the corresponding random number counter and stored in the RAM 240. The Then, the winning random number is read from the RAM 240. At this time, if it is determined that the read random number value matches the jackpot value, it is a jackpot.

  When the jackpot is reached, the jackpot type determination random number is read from the RAM 240 through step S310, and the gaming state number of the order of the read random number value is read from the jackpot type determination table 400. Next, through steps S400 to S406, the stop symbol determination table 420 and the divisor corresponding to the game state number are read, the stop symbol determination random number is read from the RAM 240, and the read random number value is divided by the divisor. Ranking information is generated. Next, through steps S408 and S410, the stop symbol number of the rank indicated by the generated rank information is read from the stop symbol determination table 420, and a designation command is placed in a predetermined area of the RAM 240 based on the read stop symbol number. It is stored and output to the symbol control device 152. Then, the effect symbols are variably displayed, and after a predetermined variation time has elapsed, the effect combination is stopped. In addition, after the production symbol is stopped, a special prize state corresponding to the game state number occurs. In the case of a big hit, one of “short time”, “left odd”, “left even” and “2 rounds” occurs.

On the other hand, if it is determined that the read random number value does not match the jackpot value, it is determined that the read random number value matches the jackpot value through step S322. .
When it is a small hit, the game state number is set to “4” through step S330. After that, as in the case of jackpot, the stop symbol determination table 420 and the divisor corresponding to the game state number are read, and the stop symbol number of the rank indicated by the generated rank information is read. Then, the effect symbols are variably displayed, and after a predetermined variation time has elapsed, the effect combination is stopped. In addition, after the production symbol is stopped, a special prize state corresponding to the game state number occurs. If it is a small hit, a "small hit" occurs.

During the occurrence of the special prize state, the special prize opening 115 is controlled to be opened and closed with a predetermined opening / closing pattern, and when a game ball is won in the special prize opening 115, a predetermined number of prize balls are paid out per prize.
In this way, in the present embodiment, a lottery to determine which one of a plurality of special prize states is caused is performed, the stop symbol determination table 420 and the divisor corresponding to the special prize state determined by the lottery are read, and each stop A stop symbol determination random number that can take any value in the numerical range including the least common multiple of the number of records in the symbol determination table 420 is acquired, and the generated random number value is divided by a divisor to generate rank information, The stop symbol number of the rank indicated by the rank information is read from the stop symbol determination table 420, and the combination of stop symbols is determined based on the read stop symbol number.

  Thereby, in order to readjust the occurrence probability of the stop symbol for each gaming state, the configuration of the stop symbol determination table 420 corresponding to the special prize state may be changed, so that the design change is facilitated. In addition, since each stop symbol determination table 420 can be configured with the required number of records, the data capacity and processing load can be reduced.

However, the present invention is not limited to this, and the divisor corresponds to the special prize state. It is also possible to configure the number of records in the stop symbol determination table 420 to be generated and the remainder obtained by dividing the acquired random value by the divisor to be generated as rank information.
