PROBLEM TO BE SOLVED: To provide a game machine capable of acquiring random number values necessary for lottery processing at a required timing for security and game control purposes.SOLUTION: A random number generation circuit GNR is provided, the circuit including: a number sequence generation group 33G repeating update operations; a pulse output part 30 outputting detection pulses LT when a switch signal is in an ON state; a latch group 34G capable of storing output values of the number sequence generation group 33G at a timing of receiving the detection pulses LT; and a latch register 35b capable of acquiring values of the latch group 34G. The random number generation circuit GNR includes first means for storing a storage value of the latch group 34G in the latch register 35b corresponding to the first detection pulse, and second means for overwriting and storing a storage value of the latch group 34G in the latch register 35b corresponding to the detection pulse after that; the storage values of the latch register 35b are cleared when a CPU acquires the storage values of the latch register 35b. |
