PURPOSE: To improve a game property full of variety by deciding whether it is a normal probability or a high probability by a drawn random number value and notifying a player of a change to the high probability based on high probability decision signals in the case of the high probability. CONSTITUTION: When the player operates a start switch 25, by start signals being inputted to a probability drawing means 51, the probability drawing means 51 draws one random number value from the random number values successively generated from a random number generation means 52 and outputs a probability drawing signal to a probability decision means 53. The probability decision means 53 decides whether it is the normal probability or the high probability based on the random number value drawn in a prize drawing means 56 and drawing probability data held inside the probability decision means 53. Then, when a decided result is the high probability, the probability decision means 53 outputs the high probability decision signals to a lamp lighting control means 57, an effective sound generation means 58 and a probability selection means 54, a lamp 30 is lighted and the generation of effective sound in a speaker 31 is started. |
