ABSTRACT:
A dual-path ramp for pinball games is formed of a single plastic member and has a plurality of entrances from the game playfield and exits back onto the playfield. The geometry of sides of the ramp is such that the ball, as it travels adjacent to one of the sides, is directed into a plurality of patterned grooves in the bottom surface of the ramp, which, in turn, direct the path of the ball back to the sides in a criss-cross pattern. In a second embodiment, ball guides, rather than grooves, are used to cause the ball to follow one side or the other of the ramp instead of criss-crossing back and forth.
