PROBLEM TO BE SOLVED: To provide a game machine capable of flexibly announcing a game state according to the specification of the game machine while preventing fraudulence such as deliberately increasing the winning probability on a game parlor side to invite players into the game parlor at the start of business hours. SOLUTION: A main control board 101 for controlling the game state includes a main RAM 101c for storing information on the game state and abnormal information suggesting that a high-probability game state is determined while it is determined that the result of prescribed arithmetic operation for finding the ratio of entrance and discharge of game balls (=total put-out balls/total out balls) is a specific value with an abnormally high ratio of entrance of game balls (e.g. 150% or higher) till the operation of a RAM clearing switch 101d is detected. At least when the abnormal information is stored or after the power shut-off is restored, the main control board transmits a game state signal and an abnormal information signal to a presentation control board 102. Meanwhile, the presentation control board 102, when receives the high-probability game state signal and the abnormal information signal, makes a display device announce that the a game is in the high-probability game state.
