PROBLEM TO BE SOLVED: To detect and prevent a fraud such as fraudulently dispensing game balls using a counterfeited or altered prepaid card or the like and exchanging them with a prize. SOLUTION: CPU 66 reads the contents of a dispensing record table (step 701) and determines whether or not the dispensed game balls are normally used for a Pachinko game (step 702). When determining it is not normal (step 703: NO), the CPU 66 outputs a fraudulence signal (step 704). This game machine actuates an alarm device or the like based on the fraudulence signal and notifies the occurrence of the fraud to a manager and a parlor clerk so as to be effective for the detection and the prevention of the fraud such as fraudulently dispensing the game balls using the counterfeited or altered prepaid card and exchanging them with the prize.
