<p>PROBLEM TO BE SOLVED: To provide a game machine capable of executing each kind of lottery processing in a state where a security level is being maintained without increasing a game control load of a CPU.SOLUTION: A random number generation circuit GNR includes: a numerical value update part 33G for updating a numerical value by repeating update operation; a random number acquisition part 34G capable of acquiring a numerical value of the numerical value update means 33G in accordance with a switch signal; and an abnormality detection part 36 for detecting abnormality in the numerical value update part 33G. The numerical value update part 33G is divided into an ordinary circuit 41b and a special circuit 41a. When the abnormality detection part 36 detects abnormality in the special circuit 41a, the subsequent update operation is allowed to continue based on a system clock.</p> |
