<p><P>PROBLEM TO BE SOLVED: To prevent a player from predicting a result of a sorting operation in an accessory device. <P>SOLUTION: A special symbol is stopped and displayed as a winning symbol.When a determined time T14 passes, a jackpot pocket solenoid is turned on and a first open/close operation is performed by a movable ball-entry accessory device (time t13). The first open/close operation ends within a short open time T15 in which a ball hardly enter a pocket in the first opening/closing operation, and the jackpot pocket does not open until an arbitrary standby time duration T16 passes. Accordingly, it is possible to arbitrarily set the time to the second and subsequent opening where the ball actually enters the pocket (D). In addition, an ON/OFF pattern of a first stopper solenoid is irregular (E), and it is difficult to predict a timing of storage release, it is possible to prevent a prior determination as to whether it is possible to win a prize V or not (F). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
