PROBLEM TO BE SOLVED: To provide a game machine capable of improving security strength.SOLUTION: A main control unit switches a "control command transmitted this time" and an "error inspection value generated this time" for storage as inspection value generation information according to the error inspection value generated this time (steps S742 to S744). Then, the main control unit generates an error inspection value at the next time or thereafter by the bit information of the inspection value generation information, and adds the value to the control command (step S745) for transmitting it to a performance control unit (step S746). A subsequent stage control unit performs an error inspection of the control command acquired by the performance control unit for transmitting it to the performance control unit. Thus, it is made difficult for a person who performs a fraudulent act to analyze a relationship between the control command and the error inspection value added to the control command by a simple method. Therefore, it is made difficult for the person who performs a fraudulent act to perform a fraudulent act even if the person who performs a fraudulent act exploits the control command and the error inspection value added to the control command, and the security strength of a game machine can be enhanced by the simple method. |
