A bumper assembly for use in pin-ball games. The bumper assembly includes a plurality of bumpers that are connected by shafts to a kicker arm which is fixed to the core of the solenoid such that the plurality of bumpers are controlled together by the solenoid and only a single solenoid is required for all the bumpers. The playing surface and bumper are electrically conductive and are electrically connected to the solenoid. The ball played with the game is electrically conductive and will complete the electrical circuit between the bumper and playing surface to cause energization of the solenoid which will cause the bumper to move downwards and further cause the ball to be projected away from the bumper.
