PURPOSE:To improve the interest, and also, to prevent the oversight of switching to a first state of a variable prize-winning ball device by providing the variable prize-winning ball device being freely variable to a first state being advantageous and a second state being disadvantageous to a player, and varying continuously the prize-winning probability of a hit ball to this device. CONSTITUTION:The pinball game machine, etc., are provided with a variable prize-winning ball device being freely variable to a first state driven in the opening direction being advantageous to a player, which is apt to receive a hit ball hit into a game area, and a second state driven in the closing direction being disadvantageous to the player. Also, a game controller 60 is provided with a specific game state detecting means 63 for detecting a fact that a game state becomes a specific game state determined so as to be able to give prescribed game value. In such a state, based on its detection output, by a driving control means 65, a reciprocating operation for allowing the variable prize- winning ball device to repeat alternately a first state and a second state is subjected to driving control continuously plural times until it is completed to give the prescribed game value, and also, in the course of this alternate driving control, an informing circuit 66 is operated. |
