<p><P>PROBLEM TO BE SOLVED: To vary a likelihood of winning a jackpot game without varying a probability of winning or losing in an electric lottery related to a spacial pattern in a Pachinko machine equipped with a movable prize winning device. <P>SOLUTION: A special pattern control processing part 100C causes a display device 5 to start varying a special pattern at the timing when a starting port detection device 200 detects a play ball. At that timing, a winning control means 104 controls a motor M so that an attitude of a distribution body of the movable winning device 1 is changed in a fixed pattern, and controls a solenoid Sol1 so that a big winning port is opened by an opening/closing body with a given period of elapsed time after varying the special pattern is stopped. A variation time determination means 103 determines the variation time by referring to first and second tables. The variation time in the first table is the length for opening the big winning port in such a state of the distribution body that it is difficult for all the game balls to pass through a special area. The variation time in the second table is the length for opening the big winning port in such a state of the distribution body that it is easy for all the game balls to pass through the special area. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
