<p>PROBLEM TO BE SOLVED: To provide a pinball game machine capable of advance-noticing successes precisely without reducing the success number so that the machine can exploit a read-ahead function sufficiently.SOLUTION: When the reservation memory of a special pattern is stored as a result of a ball entry into a start port, a main control unit 30: confirms whether or not a random number for deciding the propriety of a starting port of the reservation memory is a success at either an ordinary probability or a high probability of game state; confirms whether or not the random number for deciding the special pattern of the reservation memory is at either the special pattern varying to the ordinary probability or the special pattern varying to the high probability; decides a read-ahead decision signals of plural kinds on the basis of the confirmation result of the deciding random number and the confirmation result of the pattern deciding random number; and sending the read-ahead decision signal to an auxiliary control unit 35. An auxiliary control unit 35 having received the read-ahead decision signal executes the read-ahead performance predicting the success in the future if the combination of the read-ahead determination signal received at this time and the read-ahead determination signal received before is the predetermined condition.</p> |
