Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine that executes a series of gaming programs at regular intervals by reset, timer interruption, etc., and in particular, a display result of identification information variably displayed on a variable display device capable of displaying a plurality of types of variable display modes The present invention relates to a gaming machine that can generate a specific gaming state advantageous to a player when a predetermined display result is obtained.
[0002]
[Prior art]
In pachinko machines equipped with game control means for controlling the progression of games in the game area formed on the game board, as a conventionally known control method, game control processing executed by the game control means is an island facility. In order to prevent the occurrence of an abnormal situation due to runaway due to noise generated from the ball that circulates within the system, the program is reset every fixed time (for example, every 4 milliseconds), and the program Control by a reset method that starts control from the top is performed.
[0003]
By the way, in a current pachinko machine, for example, a variable display device that displays a variable display plays a variable display game in which a pattern changes based on a winning at a starting port, and derives a specific display mode such as a doublet. There is one that gives a player a jackpot or the like that opens a winning opening (so-called one kind of pachinko machine).
[0004]
In such a pachinko machine, whether or not to generate a big hit is generally determined by a big hit random value obtained by a game, and the random number such as the big hit random value is incremented by a predetermined value by adding “1” at each reset. Using a counter that exceeds the initial value (0), the value obtained by changing the acquisition timing of the counter value is created by a method having randomness (so-called +1 random number generation) method). In particular, the timing with which the counter value for random numbers is obtained is most asynchronous when using timing related to a game ball, such as a game ball winning timing at the start opening, which is completely asynchronous with the operation clock of the control system. can get.
[0005]
The jackpot random number value is acquired when winning at the start opening, and compared with a jackpot determination random number value (for example, “7”, etc.) at the time of determination (for example, determination at the start of variable display), and is determined to be a jackpot If it is determined that the stop symbol is stopped at the big win symbol in the variable display game by the variable display device, and if it is not determined to be a big hit, control is performed so as to stop at the loss symbol in the variable display game. ing.
[0006]
There are a number of random numbers used during the operation of the pachinko machine, such as a jackpot symbol creation random number, a loss symbol creation random number, a reach variation display random number, a reach announcement random number, a probability variation random number, etc. In general, all the random numbers are generated by the above-described +1 random number generation method, and each random number value is acquired at a predetermined acquisition timing.
[0007]
In this way, with a pachinko machine, various random numbers are acquired according to predetermined conditions such as winning at the start opening, and the random number value is compared and determined when it fluctuates, so that various variations such as loss fluctuation, reach loss fluctuation, jackpot fluctuation, etc. It runs a variety of variable display games and offers an entertaining game that makes it difficult for players to get bored. For example, even if it is a loss variation, the reach state is not reached, but some effect (for example, when the symbol changes from the low speed variation state to the stop state, the state in which the two symbols are stopped after frame advance is 4 There are multiple types of “slip design” that can be stopped after more frames, etc., etc., and there are dozens of types of effects regarding reach fluctuations. is there.
[0008]
[Problems to be solved by the invention]
In the past, however, the distribution of dozens of effects (variable display modes) is compared with each judgment value associated with the number of effects (numbers or types) using one random number. Had gone by.
[0009]
In this case, since it is necessary to compare the random number value and each determination value one by one, it takes a processing time and there is a disadvantage that the number of effects cannot be increased much.
[0010]
That is, for example, when 50 types of variable display modes are distributed, when 50 determination values are used in association with the determination values for each of the variable display modes, a maximum of all 50 determination values are used. Processing for comparing random values (for example, 0 to 999) is required. Therefore, for example, in a gaming machine having a specification in which the execution time of the entire program is determined in advance, such as a reset interrupt every few milliseconds, a series of programs can be obtained if it takes too much time to distribute the above-mentioned fluctuations. There is a possibility that a reset interrupt occurs before the process is completed and the process is not completely completed.
[0011]
In addition, in order to prevent the occurrence of such a situation, it is necessary to take measures such as simplifying other processes, and there may be a situation where the required game process and effect process cannot be performed sufficiently.
[0012]
In addition, a high-speed arithmetic processing unit (CPU) is required in order to reliably complete the processing involving the distribution of a large number of variable display modes within the reset period, leading to a rise in gaming machines and various regulations. In many cases, a desired high-speed CPU cannot be employed.
[0013]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine that can distribute a large number of variable display modes in a short time without using a high-speed CPU.
[0014]
[Means for Solving the Problems]
  In order to achieve the above object, the present invention has a special symbol display (102) for variably displaying a symbol, and the symbol is varied in a predetermined variation display mode from a plurality of variation display modes on the special symbol display. Displayed, the stop display result became a specific display result set in advanceCaseIn a gaming machine capable of generating a specific gaming state advantageous to the player,SaidpluralFluctuation display modeA number of consecutive sorting data associated with each of theTable dataAnd a table data storage means for storing a random number for determining a predetermined variation display mode from the plurality of variation display modes, and selected from the plurality of distribution data based on the generated random number The distribution data to be determined is determined, and the determined distribution data is stored in a predetermined storage area.Distribution data update valueSet asRandom number management updating means (steps S1 to S15 in FIG. 6),in frontSet by the random number management update meansSaidBased on distribution data update valueStrangeAnd a variable display mode determining means (game microcomputer 211) for determining a dynamic display mode.In the table data stored in the table data storage means, different random number upper limit values are set in order to limit the range of the random numbers corresponding to the plurality of distribution data, and the random number management updating means Updating means for updating the random number at regular intervals; and determining means for determining whether the updated random number has reached the random number upper limit value corresponding to the distribution data update value in the table data; Setting means for setting the distribution data update value based on the determination result of the determination means, wherein the setting means is determined by the determination means that the random number has reached the random number upper limit value The distribution data adjacent to the distribution data currently set according to the order is set in the predetermined storage area as the distribution data update value, If it is determined by the determining means that the random number has not reached the random number upper limit value, the currently set distribution data is set again in the predetermined storage area as the distribution data update value, and the fluctuation The display mode determination unit acquires the distribution data update value set by the setting unit when starting the variation of the symbol, and determines the predetermined variation display mode based on the acquired distribution data update value DoI did it.
[0015]
Here, the fluctuation display mode refers to a state from when the symbol starts to change until the change is stopped, and includes various modes such as loss fluctuation, reach loss fluctuation, jackpot fluctuation, and the like.
[0016]
According to this, since the distribution of the variable display mode is performed by a method of extracting management information grouped in advance for each variable display mode, the number of display modes can be determined using one random number as in the past. The process of comparing with the corresponding determination values is not required, and the time required for distributing the variable display mode can be shortened.
[0017]
Therefore, even without using a high-speed CPU, it is possible to increase the number of variation display modes such as loss variation symbols, reach loss variation symbols, jackpot variation symbols, etc., and further diversify the production and enhance the interest. Can do.

[0026]
Although not particularly limited, in this embodiment, a micro switch or a non-contact type is used to detect a ball that has won a prize corresponding to each of all the winning holes 103 to 111 provided in the game board 100. A winning sensor composed of sensors is provided. That is, a special figure start sensor SS1 is arranged inside the special figure start winning port 103, a count sensor SS4 and a continuous winning sensor SS5 inside the variable winning device 106, and a prize sensor inside the general winning ports 107-111. SS4 to SS10 are respectively arranged.

It has come to be.
[0027]
Here, when the passing ball to the normal figure starting gates 104 and 105 is detected, the normal symbol display 122 is operated to display a fluctuation for a predetermined time, and during that time, the passing ball to the normal figure starting gates 104 and 105 is further displayed. When it occurs, the number of balls is stored, and the normal start winning memory display 123 is turned on according to the stored number. Then, when the display of the fluctuation on the normal symbol display 122 stops and the display content is in a predetermined form, the special figure start winning port 103 made of the above-mentioned normal electric accessory is opened.
[0028]
When a game ball wins the opened special figure start winning port 103 or the closed special figure start winning port 103, the specific symbol display 102 is operated to display a fluctuation for a predetermined time, and during that time the special figure start winning port is further displayed. When a winning ball to 103 is generated, the number of balls is stored, and the special figure starting winning memory display 121 is turned on according to the stored number.

Then, as will be described later, after determining the random number value extracted in relation to the winning to the special start winning opening 103, in the special symbol display 102 in order to derive the stop symbol corresponding to the determination result After a predetermined time has passed since the variable display is started, the variable display is terminated to stop at the stop symbol.
[0030]
Next, when the determination result related to the variable display is a success after the end of the variable display, the variable winning device 106 is opened until a predetermined time or a predetermined number of winning balls is reached.
[0031]
Further, the variable winning device 106 is provided with a general winning region and a continuous winning region, and the opening operation of the variable winning device 106 is repeated a predetermined number of times on condition that a game ball has been won in the continuous winning region. It is.

[0034]
  As shown in FIG. 5, the random number value is generated until a random number update process (P2) provided in the middle of the main game program and a next interrupt signal (reset signal) provided at the end of the program are received. Residual time processing performed within the remaining time (P13)InDone. In addition, random number extraction and determination is handled by special game processing (P4).LeaveDone.
[0035]
Since the game control device 200 has different control contents for each game board, it is usually replaced with a new one when the game board 100 is replaced. Therefore, generally, the game control device 200 is configured to be attached to the back side of the game board 100 and exchanged together with the game board. However, it is not necessarily limited to such a configuration.
[0036]
FIG. 2 shows a configuration example of the game control device 200 that controls the progress of the game and the generation of random numbers on the game board, and the relationship between the input / output components.
[0037]
As shown in FIG. 2, the game control device 200 includes a game microcomputer 211 composed of a one-chip microcomputer (broadly defined CPU) that is a semiconductor integrated circuit that performs control of an object necessary for a pachinko game, etc., and a crystal A clock generation circuit 212 that divides an oscillation signal of an oscillator to obtain a clock signal of a predetermined frequency, an input interface 213 that receives signals from various sensors, a driving signal for driving means such as a solenoid, and other control devices And an output interface 214 for outputting a control signal.
[0038]
The gaming microcomputer 211 incorporates a central processing unit (CPU) as arithmetic control means, ROM (read only memory) and RAM (random access memory), interrupt control circuits (not shown), etc. as storage means. It is manufactured as an IC for so-called amuse chips. Programs and prize ball number data necessary for game progression control performed by the CPU are stored in the ROM.
[0039]
The ROM of the gaming microcomputer 211 stores variation pattern data for distributing the variation display mode based on random values in a table format.
[0040]
For example, as shown in FIG. 4, the data of the fluctuation pattern is divided into a pattern (a) in the case of a loss fluctuation and a pattern (b) in the case of a big hit fluctuation and stored.
[0041]
In this embodiment, the “random number upper limit value” is information that limits the range of random number values.
[0042]
Each variation pattern is grouped by, for example, distribution data of 1 to 50. In the pattern (a) in the case of loss variation, the random number upper limit value “600” corresponding to the distribution data “1”, variation display contents “Specify fluctuation pattern 1” (that is, change all special symbols for 5.2 seconds), Random number upper limit value “200” corresponding to distribution data “2”, and “Display fluctuation pattern 2 as fluctuation display contents” ”(That is, all special symbols are changed for 9.6 seconds), the random number upper limit value is“ 100 ”corresponding to the distribution data“ 3 ”, and“ variation pattern 3 is specified ”as the variable display content (ie, all special symbols) Is changed for 10.0 seconds), the random number upper limit value is “10” corresponding to the distribution data “50”, and “variation pattern 50 is designated” as the variation display content (that is, all special symbols) Storing data such as the order) varies 40.0 seconds in a table format.
[0043]
Similarly, in the pattern (b) in the case of big hit fluctuation, the random number upper limit value “11” is associated with the distribution data “1”, and “variation pattern 1 is designated” as the fluctuation display content (that is, all special symbols are 5). .. 2 seconds) corresponding to the distribution data “2”, the random number upper limit value “20”, and “variation pattern 2 is designated” as the variation display content (that is, all special symbols are varied for 9.6 seconds). Corresponding to the distribution data “3”, the random number upper limit value “30”, the variable display content “designate the variation pattern 3” (that is, all special symbols are varied for 10.0 seconds), and the distribution data “50” Corresponding to the random number upper limit value “100”, and data such as “specify the fluctuation pattern 50” (that is, change all the special symbols for 40.0 seconds) as the fluctuation display contents are stored in the form of a table.
[0044]
Then, the random number for big hit time display, the random number for fluctuation display at the time of loss, the updated value of the distribution data for big hit, and the updated value of the distribution data for loss are managed and updated in the random number update process described later. Each is written to a predetermined area in the RAM.
[0048]
Note that the gaming microcomputer 211 is provided with a backup power source 500 that supplies power to the gaming control device 200 for holding various data stored in the RAM when a power failure occurs.
[0049]
The game control device 200 receives, via the input interface 213, a signal from the prize ball detection sensor 304 in the ball discharge device, a signal from the overflow detector 301 that detects that the tray is full of game balls, A signal from the half-end ball detector 302 that detects the presence or absence of a game ball that can be supplied to the discharging device, and a metal frame opening detector that detects that the metal frame that holds the glass plate covering the front side of the game board 100 is opened. The signal from 303, the special figure start sensor SS1 in the special figure start winning port 103, the general figure start sensors SS2 and SS3 in the general figure start gates 104 and 105, and the VV corresponding to the continuous winning area in the variable prize winning device 106. The winning sensor SS4, the count sensor SS5 corresponding to the general winning area, and detection signals from the winning sensors SS6 to SS10 in the general winning ports 107 to 111 are input. That.
[0050]
On the other hand, from the game control device 200, via the output interface 214, the display drive signal for the normal symbol display 122 and the general diagram start winning memory display 123, and the drive signal for the general electric solenoid 315 for opening and closing the normal electric accessory. , A data signal for the special symbol display device 400, a display driving signal for the special symbol start winning memory display 121, a driving signal for the attacker solenoid 314 for opening and closing the large winning opening of the variable winning device 106, a discharge control device 220, and a decoration control device 240, a data signal to the sound control device 250, a signal to the terminal 311 for outputting the internal state at the time of the test, a signal to the data output terminal 312 for transmitting data to the management device of the game store (not shown), and the like.
[0051]
FIG. 3 shows a special symbol display 102 formed of a liquid crystal display device or the like provided on the game board, and a display control device 420 for driving and controlling the special symbol display 102 based on a data signal from the game control device 200. The example of a structure of the special symbol display apparatus 400 as a fluctuation | variation display apparatus which consists of is shown.
[0052]
The display control device 420 provides a control microcomputer (CPU) 421, an interface circuit 422 with the game control device 200, a read-only memory (ROM) 423 for storing control programs and fixed data, and a work area for the control CPU 421. Or random access memory (RAM) 424 for storing data and display data sent from the game control device 200, an image display controller (VDC) 425 for driving the special symbol display 102, and display image data. Stored font ROM 426, γ correction circuit 427 for display correction, DMA controller (DMAC) 428 for transferring data from RAM 424 to image display controller 425, DMA oscillator (428), crystal oscillator oscillation signal divided and predetermined Frequency of black It consists of a clock generation circuit 429 to obtain a click signal.
[0053]
Display control information such as display variation time data, stop symbol data, and stop command is input to the control CPU 421 of the display control device 420 from the game control device 200 via the interface 422. When display control information is input from the game control device 200, a reception interrupt is generated from the interface 422 to the control CPU 421, and the control CPU 421 stores the received data (display control information) in the buffer area of the RAM 424 accordingly. To do.
[0054]
Then, the control CPU 421 analyzes the received data, for example, determines an effect pattern (collection of continuous display symbol data) to be variably displayed based on the variation time data, and displays a code, a display position, and a scroll indicating the symbol to be displayed. Are generated and stored in the RAM 424. The effect patterns are stored in advance in the ROM 423 in the form of a table corresponding to the variation time data.
[0055]
This production pattern corresponds to the above-mentioned variation pattern. For example, if the variation pattern is “1”, “all special symbols are varied for 5.2 seconds”, and if the variation pattern is “2”, “all Variation display according to the distribution process of the variation display mode is performed such that the special symbol is varied for 9.6 seconds.
[0056]
The image display controller 425 reads the data group corresponding to the effect pattern transferred from the RAM 424 by the DMA controller 428 into the internal RAM and develops it. Specifically, the character font data stored in the font ROM 426 is read according to the code indicating the design, and the image data to be displayed is associated with the display screen according to the display position data and command, and the display image in the internal RAM. Store in the storage area. At this time, a background symbol for enhancing the effect is generated separately from the variation symbol for the special figure game such as a number and stored in the display image storage area. The variation symbol and the background symbol may be combined and stored, but may be combined when separately stored and read.
[0057]
Thereafter, the image display controller 425 reads display image data from the display image storage area of the built-in RAM and sequentially sends it to the γ correction circuit 427 to form a display drive signal for the special symbol display 102. At this time, the scroll for the variable display is performed by the image display controller 425 changing the start position of the image data to be displayed by the address calculation according to the command and parameters such as the scroll speed. Further, the image display controller 425 sends a vertical synchronization signal V-SYNC and a horizontal synchronization signal H-SYNC to the special symbol display 102. The γ correction circuit 427 adjusts the display illuminance of the display device by correcting the non-linear characteristic of the illuminance with respect to the signal voltage of the display device. Thereby, a predetermined display is performed on the screen of the special symbol display 102.
[0058]
Next, with reference to FIG. 5, the main process of the game program performed by the game microcomputer 211 of the game control device 200 will be briefly described.
[0059]
FIG. 5 is a flowchart showing an example of the processing procedure of the game program executed by the reset interrupt.
[0060]
The game microcomputer 211 starts the game program every time a reset signal (for example, output by a predetermined timer (not shown)) is input every 4 msec.
[0061]
Roughly speaking, among the series of game programs, the processes P1 to P12 complete the process within 4 msec which is the reset interval, and perform the remaining time process P13 within the remaining time until the next reset signal is input. It is designed to be repeated.
[0062]
When the game program P is started, input processing P1 is first executed. The input process P1 is a process of determining a signal input state of a predetermined detector (sensor) provided on the game board such as the winning sensors SS6 to SS10.
[0063]
Next, a random number update process P2 is executed. This process constitutes random number management update means. Details of processing contents will be described later.
[0064]
  The random number update process P2 includes a process of adding “1” to the value of the internal counter for generating random numbers. There are various types of game random numbers, such as random numbers for jackpot determination and random numbers for determining outliers, but all these random numbers are updated.TheThis processMay.
[0065]
Subsequently, the state of input signals from various switches (detectors) provided on the game board is read. For example, when the level changes from low level to high level and the high level continues twice, it is determined that there is a detection signal and the input flag is set. The standing switch monitoring process P3 is performed, and the process proceeds to the special figure game process P4. The special symbol game process P4 is a process of starting the variable display on the special symbol display 102 and stopping the variable display at a stop symbol determined based on the random number value after a predetermined time. In addition, the variation pattern determination process which acquires distribution data is performed in the subroutine in the special figure game process P4. Details of processing contents will be described later.
[0066]
Next, the process shifts to the normal game process P5 to set a flag for controlling the variable display on the normal symbol display device 122, or to generate a sound effect command to the sound control device in accordance with the normal display state. A command for giving a decoration display command to the decoration control device is set, and processing such as an effect display at the time of starting a general map is performed. Then, in the next process P6, the normal map change process P6 for setting the data for displaying the variable map in the output area based on the information set in the process P5 is performed, and then the process proceeds to the fraud monitoring process P7. To do.
[0067]
In the fraud monitoring process P7, a fraud monitoring process for determining whether or not the gaming control device 200 is fraudulent is performed based on a signal from the gold frame opening switch 302, the prize ball detection sensor 304, or the like or an internal control state.
[0068]
Next, on the basis of the processing state (game state) in the special figure game process P4 or the general figure game process P5, the special figure start winning port 103 made up of a solenoid or an ordinary electric accessory for opening the variable winning device 106 is formed. Solenoid editing processing (P8) is performed in which on / off data for outputting a signal for controlling the solenoid for performing the operation to the corresponding output port is set in the output region. Subsequently, an external information editing process (P9) for setting data for transmitting a jackpot signal, a special figure fluctuation signal, or the like to the management device based on the processing state in the special figure game process is performed.
[0069]
Thereafter, a prize ball discharge command for the discharge control device 220 set in the input determination process and special figure game process routine, a winning memory display for the decoration control device 240 and drive commands for various lamps, and sound generation for the sound control device 250 A series of command editing processes P10 for rearranging commands in the order of transmission is performed.
[0070]
Next, a series of command transmission processing P11 is performed in which the commands edited in the command editing processing P10 are rearranged in the order of transmission and set in the output area. Subsequently, an output process P12 for outputting the signal by setting the output data set in the output area in the command transmission process P11 to the output port is executed, and the process proceeds to the remaining time process P13.
[0071]
This remaining time process P13 is a process for generating a random number, and is repeatedly executed using the remaining time until the next reset signal is input after each process of P1 to P12 is completed. Generate random numbers with variation.
[0072]
Next, a specific example of the random number update process P2 will be described with reference to the flowchart of FIG.
[0073]
This random number update process constitutes a random number management update means. First, in step S1, a random number value for big hit change display and a random value for change display at loss are acquired. The random number for fluctuation display at the time of big hit and the random number for fluctuation display at the time of loss are obtained from a predetermined area of the RAM in the gaming microcomputer 211, but the data is still stored in the first processing after the game machine is started up. Since it is not done, “0” is acquired as an initial value.
[0074]
Next, the process proceeds to step S2, and the random number value for fluctuation display at the time of big hit and the random number value for fluctuation display at the time of loss are incremented by +1 to update the random number value, and then the process proceeds to step S3.
[0075]
In step S3, distribution data values for big hits and loses are acquired. The big hit and lose distribution data is obtained from a predetermined area of the RAM in the gaming microcomputer 211, but since the data has not yet been stored in the initial processing after the game machine is started up, Distribution data “1” is acquired.
[0076]
Next, in step S4, a random number upper limit value corresponding to the distribution data is acquired, and the process proceeds to step S5. That is, when the loss distribution data acquired in step S3 is “1”, the random number upper limit value “600” is set, and when the distribution data is “2”, the random number upper limit value “200” is set. Is “3”, the random number upper limit value “100” is acquired, and when the distribution data is “50”, the random number upper limit value “10” is acquired. Similarly, when the big hit distribution data acquired in step S3 is “1”, the random number upper limit value “11” is assigned. When the distribution data is “2”, the random number upper limit value “20” is assigned. When the data is “3”, the random number upper limit value “30” is acquired, and when the distribution data is “50”, the random number upper limit value “100” is acquired.
[0077]
In step S5, it is determined whether or not the random value for the big hit hour fluctuation display has reached the upper limit value. That is, when the random number value for the big hit fluctuation display updated in step S2 is compared with the random number upper limit value acquired in step S4, if the random value has reached the upper limit value, YES is determined and the process proceeds to step S6. If the upper limit has not been reached, NO is determined and the process proceeds to step S10.
[0078]
In step S6, a random number value (for example, “11”, “20”, etc.) for big hit change display is set to “0” which is an initial value, and then the process proceeds to step S7.
[0079]
In step S7, the big hit distribution data is incremented by +1 and then the process proceeds to step S8 (for example, if the distribution data is “1”, it is updated to “2”).
[0080]
In step S8, it is determined whether or not the distribution data is larger than the maximum value (for example, “50” in the example of FIG. 4B). If YES, the process proceeds to step S9. If NO, step S10 is performed. Migrate to
[0081]
In step S9, the big hit distribution data is set to the initial value “1”, and then the process proceeds to step S10. In step S10, it is determined whether or not the random number value for displaying the variation at the time of the loss is an upper limit value (such as “600” in the example of FIG. 4A). That is, when the random number value for fluctuation display at the time of updating updated in step S2 is compared with the random number upper limit value acquired in step S4, if the random number has reached the upper limit value, YES is determined and the process proceeds to step S11. If the upper limit has not been reached, NO is determined and control proceeds to step S15.
[0082]
In step S11, a random number value for display of change in loss (for example, “600”, “200”, etc.) is set to “0” which is an initial value, and then the process proceeds to step S12.
[0083]
In step S12, the distribution data for losing is incremented by +1, and then the process proceeds to step S13 (for example, if the distribution data is “1”, it is updated to “2”).
[0084]
In step S13, it is determined whether the distribution data is greater than the maximum value (for example, “50” in the example of FIG. 4A). If YES, the process proceeds to step S14. If NO, step S15 is performed. Migrate to
[0085]
In step S14, the loss distribution data is set to “1” which is an initial value, and then the process proceeds to step S15.
[0086]
  In step S15, each value updated in the processing of step S1 to step S14 is stored in each predetermined storage area in the RAM of the gaming microcomputer 211, and the process proceeds to the subsequent processing. The processes performed after step S15 include a jackpot determination random number update process, a jackpot symbol random number update process, and the like, but details thereof are omitted.
  As described above, for example, in the distribution of the loss variation pattern, when the distribution data (distribution data update value) “1” is acquired from the predetermined area of the RAM, it is updated (+1 increment) every 4 msec reset interrupt. Until the random number value reaches “600”, the distribution data in the RAM continues to be set to “1”. When the random number value reaches “600”, the random number value becomes “0” and the distribution data in the RAM is updated to “2”. Next, when the distribution data “2” is acquired from the predetermined area of the RAM, the distribution data of the RAM is kept until the random value updated (+1 increment) every 4 msec reset interrupt reaches “200”. Continues to be set to “2”.
  On the other hand, for example, in the case of distribution of the big hit variation pattern, when the distribution data “1” is acquired from the predetermined area of the RAM, the random number value updated (+1 increment) every 4 msec reset interrupt is “11”. Until reaching, the distribution data in the RAM continues to be set to “1”. When the random number value reaches “11”, the random number value becomes “0” and the distribution data in the RAM is updated to “2”. Next, when the distribution data “2” is acquired from the predetermined area of the RAM, the distribution data in the RAM is kept until the random value updated (+1 increment) every 4 msec reset interrupt reaches “20”. Continues to be set to “2”.
[0087]
Next, a specific example of the variation pattern determination process performed in the subroutine in the special figure game process P4 will be described with reference to the flowchart of FIG. Note that this processing is performed immediately after the start winning or when the start memory exists and immediately before the change starts.
[0088]
  First, in step S100, it is determined whether or not the fluctuation result is a big hit. If it is a big hit, the process proceeds to step S101.From a predetermined area of RAMAfter the big hit distribution data is acquired, the process proceeds to step S103. If it is not a big hit, go to step S102From a predetermined area of RAMAfter the loss distribution data is acquired, the process proceeds to step S103.
[0089]
In step S103, the obtained distribution data is assigned a variation pattern number (for example, in the example of FIG. 4, “variation pattern 1” for distribution data “1”, “variation pattern 2” for distribution data “2”, etc.). After specifying, return to the main routine.
[0090]
With the above processing, the distribution data is updated every time the random number reaches the random number upper limit value, and the variation display pattern is represented by variation pattern 1 → variation pattern 2 → as shown by arrows in FIGS. 4 (a) and 4 (b). ... → Change pattern 50 → Change pattern 1 →...
[0091]
  In this way, the distribution of the variation display mode isTo be done as aboveThe processing time can be shortened as compared with the conventional case where one random number is used to compare each display value with the number of display modes. In other words, in the past, for example, when there are 50 groups of random number judgment ranges, the random number value and the judgment value may be compared up to 50 times, but according to the method of this embodiment, The process of comparing the random value with each determination value becomes unnecessary, and the time required for distributing the variable display mode can be shortened.
[0092]
Therefore, even without using a high-speed CPU, it is possible to increase the number of variation display modes such as loss variation symbols, reach loss variation symbols, jackpot variation symbols, etc., and further diversify the production and enhance the interest. Can do.
[0093]
In this embodiment, the maximum random number is used as the information for limiting the range of the random number value. However, the present invention is not limited to this, and for example, the minimum random value can be used. In this case, in step S2 and the like in FIG. 6, the random number value and the like are updated by decrementing by -1.
[0094]

Should be considered. That is, the technical scope of the present invention should not be construed restrictively based on the description in the above embodiment, but should be construed according to the description of the claims to the last.
