PROBLEM TO BE SOLVED: To enable the estimation of possible troubles in the structure of outputting the random numbers. SOLUTION: When the jackpot status flag is off (step 241; No), it is determined whether the ready-to-win state should be presented or nor based on the random numbers for the ready-to-win judgment which is updated synchronously with the random numbers for the jackpot judgment (steps S244 and S245). When the ready-to-win state is presented (step S245; Yes), the frequency of normal loss counter is cleared and "1" is added to the value of the frequency of ready for win counter (steps S247 and S248). Otherwise (step S245; No), the frequency of ready-to-win counter is cleared and "1" is added to the value of the frequency of normal loss counter (steps S250 and S251). When the value of the frequency of ready-to-win counter exceeds the upper limit of the ready-to-win continuation (step S253; Yes) or when the value of the frequency of normal loss counter exceeds the upper limit of the normal loss continuation (step S255; Yes), the trouble is detected in the random number generation circuit.
