ABSTRACT:
A pinball game using a pinball adapted to be propelled along a playfield is provided. The pinball game includes a target mounted above the playfield and first and second movable objects mounted above the playfield which are movable between a closed position wherein the first and second movable objects are disposed substantially adjacent to each other and an open position wherein the first and second movable objects are disposed substantially apart from each other. A solenoid having a plunger movable between an extended position and a retracted position in response to contact of the target by the pinball. An arm rotatable about a pivot point having first and second ends displaced from the pivot point is linked to the plunger at a point spaced from the pivot point. A first link connects the first end of the arm to one of the movable objects and a second link connecting the second end of the arm to the other of the movable objects. Movement of the plunger between the extended and retracted positions causes the movable objects to move between the open and the closed positions.
