<P>PROBLEM TO BE SOLVED: To provide a Pachinko game machine hardly generating practical inconvenience and capable of effectively resisting a brute-force attack. <P>SOLUTION: A display control part selectively switches an input operation part to an input permission state in which input of a password is effective, or to an input rejection state in which input of the password is ineffective or impossible. If the password input to the input operation part in the input permission state is an appropriately generated regular password, the display control part determines that authentication is successful (S33: Yes). If the input password is not the regular password, the display control part determines that the authentication is failure (S33: No). The display control part counts the number of times of consecutive determination that the authentication is failure (S37), and when the counted number of times reaches three (S38: No), the display control part switches the input operation part from the input permission state to the input rejection state (S41). If a special symbol lottery part executes an internal lottery in the input rejection state, the display control part switches the input operation part from the input rejection state to the input permission state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
