Abstract

A pattern matching game machine of a prepaid card system including a plurality of pattern display units mounted on a shaft and arranged in parallel to one another, a drive motor for driving the display units under the control of a control circuit, a magnetic card reader and a card identification circuit. The control circuit includes a CPU (central processor unit), an operation circuit connected to said CPU, a printer for printing out the prize points scored by a player, a motor drive circuit for driving the display units based on the random number pulses and pulse signals, and a judgement circuit for judging whether or not the patterns on the display units are matched, whereby prize points are credited when the patterns are matched instead of discharging coins, and the prize points are printed out on a slip of paper when a signal indicating the end of a game is emitted.
