<p>PROBLEM TO BE SOLVED: To improve time efficiency by accelerating the consumption of retention balls waiting for the direction of variation display or the like of a design under specific conditions. SOLUTION: A retention ball consumption acceleration means is provided to simultaneously increase the number of retention balls to be consumed when a specific number of retention balls are stored, to derive a hit when the hit is included in them, and to derive a miss when no hits are included, thus improving time efficiency for deriving the lottery result of a miss when at least a specific number of retention balls are stored, and reducing a trouble where the consumption of the retention balls takes much time.</p> |
