Abstract
A pinball game contains a plurality of drop target members each mounted for vertical movement between a raised position, above the playfield of the pinball game, and a lowered position below the playfield. Each target member is maintained in its raised position by a latch, and the target member may be knocked off its latch by impact from a pinball, causing the target member to drop to its lowered position. A latch may be withdrawn from a supportive position for its target member, causing the target member to drop without having undergone impact by a pinball. Structure is provided to elevate the target members to their raised positions, and there is a controller programmed to withdraw selected latches following the elevation of the target members.
