Abstract
The play feature of the invention consists of an inclined ramp mounted for tilting motion along a single axis. A reversible electric motor, controlled by the flipper buttons, can pivot the ramp in either direction about the axis. The player, by manipulating the flipper buttons, controls the tilting of the ramp thereby to control the path of travel taken by the ball as it rolls down the ramp. The ramp is provided with a plurality of bumpers, roll over switches and out holes that allow the player to score points if the player traverses the ramp in the manner directed by the game program.
