Claims

In a gaming machine comprising a game control means for controlling a game and a power supply means for supplying power to the game control means , the game value being able to be given based on the occurrence of a specific gaming state,
The power source means
Reset signal sending means for sending a reset signal to the game control means when the power is turned on;
A power failure detection means for monitoring fluctuations in the supplied power supply voltage and outputting a power failure detection signal when a decrease in the voltage is detected;
The game control means can execute a main process repeatedly executed while looping and a timer interrupt process executed every predetermined time,
Backup storage means used as a work area at the time of execution of game control and supplied with backup power from the power supply means;
A periodic counter stored in the backup storage means and updated cyclically within a range of a predetermined minimum value and maximum value;
Detecting means for detecting the occurrence of a predetermined event in Yu technique,
Based on a detection result of said detecting means, and cyclic counter value acquisition means for acquiring a value of the periodic counter stored in the periodic counter storage means,
Based on the value of the periodic counter that the periodic counter value acquisition means has acquired, a selecting means for performing lottery of the specific game state occurs,
Reset means for resetting game control based on the input of the reset signal from the reset signal sending means;
Based on the input of the power failure detection signal from the power failure detection means, the power failure information storage means for storing a predetermined power failure information to the backup storage means,
A power failure information determination means for determining whether or not the power failure information is normally stored in the backup storage means after the game control is reset by the reset means;
An initialization unit that initializes the storage content of the backup storage unit when the power failure information determination unit determines that the power failure information is not normally stored;
An initial value generating means for generating a random value that falls within the range of the minimum value and the maximum value as the initial value of the first round of the cyclic counter after the initialization by the initializing means;
A first counter value agitation unit that sets a value generated by the initial value generation unit as a first rotation initial value of the periodic counter after the initialization of the backup storage unit by the initialization unit;
Interrupt prohibiting means capable of prohibiting the execution of the timer interrupt process for a predetermined period from the reset of the game control ,
The initial value generating means is configured by a hardware random number IC that generates a random value with a predetermined algorithm based on reception of an operation clock,
The periodic counter is updated by the timer interrupt process,
The detection means executes the detection process in the timer interrupt process,
The first counter value agitation means is in the prohibition period of the timer interrupt process before the first update of the periodic counter after the game control is reset and before execution of the first detection process of the detection means. In addition, a gaming initial value for the first round of the periodic counter is set .

  The game control means includes
  Based on the execution of the game control stored in the backup storage means and updated in a circulating manner within the range of the minimum value and the maximum value, and generates a value that becomes a cyclic initial value after the second round of the periodic counter An initial value counter to
  Second counter value agitation means for setting the value of the initial value counter as the initial value of the next round of the periodic counter based on the fact that the cyclic counter is updated and reaches the initial value of the round With
  The gaming machine according to claim 1, wherein the initial value counter is updated in the main process and the timer interrupt process, respectively.

  The game control means includes
  When the game control is reset by the reset means, the power cut-off determining means for examining whether or not the power outage information is stored in the backup storage means and determining whether the reset is accompanied by a power cut-off,
  3. A gaming machine according to claim 1, further comprising notification means for performing notification for a predetermined period of time based on a determination that the power cut-off determination means is not a reset accompanied by power-off. .
