<P>PROBLEM TO BE SOLVED: To develop long-term performance that can fully amuse a player while promoting consumption of retained balls. <P>SOLUTION: A peripheral control section stores, at each start winning, a variation pattern including a variable pattern [5/10] shortening a variation time in a multi-retained state of four retained balls, and fixed patterns [10], [20], [40] not changing the variation time despite the multi-retained state. When retaining another fixed pattern subsequent to a preceding fixed pattern, the continuation of performance with the preceding fixed pattern is developed in continuous performance with the succeeding fixed pattern under predetermined conditions. When there is a variable pattern [5/10] prior to the fixed pattern (e.g., [40]) under retention and the variation time of the variable pattern is not shortened but varied for 10 seconds, performance with the variable pattern is incorporated as performance of prior development of continuous performance with part performance based on the fixed pattern [10] of the same 10 second variation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
