PROBLEM TO BE SOLVED: To provide a game machine by which random number values for lottery can be generated in irregular timing and fraudulent action can be prevented. SOLUTION: A random number generating circuit is equipped with 8-bit counter ICs 301, 302 counting in a substantial constant cycle and capable of outputting count values, not inverted buffer ICs 303 to 306 capable of generating a plurality of random values from the count values, a 4 bit counter IC 307 selecting random number values for lottery from a plurality of random number value based on the M1 signals output from a CPU 200 in irregular intervals and capable of obtaining the random number values for the lottery, an XOR gate 309, inverter ICs 308, 310.
