Description

The present invention relates to a gaming machine such as a pachinko gaming machine, and more particularly to a gaming machine capable of playing a game.

To achieve the above object, a game machine according to claim of the present application is a game capable gaming machine (e.g., a pachinko game machine 1 and the slot machine 700), after a predetermined period of time has elapsed, the non-volatile memory ( For example, a game control microcomputer (for example, the game control microcomputer 100, the game control microcomputer 810, etc.) having a built-in control CPU (for example, the CPU 505) for executing game control in the gaming machine based on the stored contents of the ROM 506, etc. ) And a random number circuit (for example, a random number circuit 509 or the like) that is built in or externally attached to the game control microcomputer and generates numerical data that becomes a random value, the random number circuit has predetermined numerical data. Numeric value updating means that updates and outputs according to the procedure (for example, random number generation circuit 553 or random number sequence variable) Circuit 555 and the like, and random number storage means (for example, a random value register 559A (R1D) and a random value register 559B (R2D)) that capture and store the numerical data output from the numerical value updating means as random numbers. The game control microcomputer is a control determination means for making a predetermined determination by the control CPU based on the random number value generated by the random number circuit (for example, a portion where the CPU 505 executes the processing of steps S231 and S232, etc. ) And a predetermined signal (for example, random number latch signals LL1, LL2, etc. based on the first start winning signal SS1 and the second starting winning signal SS2), the numerical data output from the numerical value updating means is stored in the random number value. It is turned on when stored in the means to limit the storage of new numerical data, while the previous A predetermined flag (e.g., a random number latch flag) that is turned off when the numerical data stored in the random value storage means is read by the control CPU at the read timing of the random value and allows new numerical data to be stored. RDFM1, and RDFM2 etc.), the security check means (e.g. CPU505 to perform security checks executes step S9~ step S14 to check whether the storage contents of the nonvolatile memory is changed in the previous SL predetermined period a portion or the like), the predetermined period between a variable settable predetermined period setting means (e.g. CPU505 based on the bit number of the security time setting KSES [2-0] is or portions for performing the processing of step S1~ step S4, CP based on bit number [4-3] of security time setting KSES U505 includes a portion, etc.) and for executing the processing of step S5~ step S8, and clock signals for defining the update period of the numerical data by the previous SL numerical updating means, the operation cycle of the control CPU specified There a clock signal for the said non-volatile memory, the built in game control microcomputer, the game control microcomputer, limits the external read of said non-volatile memory other than by the control CPU Read restriction circuit (for example, internal resource access control circuit 501A) .

According to such a configuration, when the numerical data is stored in the random value storage means based on the input of the predetermined signal, the predetermined flag is turned on and storage of new numerical data is restricted. When numerical data is read from the random number storage means at the numerical value reading timing, a predetermined flag is turned off, and storage of new numerical data is permitted. Thereby, the numerical data stored in the random number storage means based on the input of the predetermined signal can be acquired as an accurate random value .

If it is determined in step S2 that the read value is “000” (step S2; Yes), the steady set time is set to a predetermined fixed time (step S3). Here, the constant setting time of the security time, regardless of the number of times the execution of the security check process based on the system reset occurrence in the pachinko game machine 1 (the number of times the player control microcomputer 100 becomes security mode) The time component is constant. The fixed time is an invariant time component that is predetermined based on the specifications of the game control microcomputer 100 in the security time, and may be any minimum value that can be set as the security time, for example.
