Bi-level pinball machine providing interlevel ball travel

Claim 1

An improved pinball machine having an inclined first playfield which includes targets and at least one flipper operable by a player for propelling a ball in play on the first playfield, the improvement comprising: (a) a second playfield substantially parallel above said first playfield; (b) a bidirectional ball path having a first open end on said first playfield and a second open end connected to said second playfield, said first end opening toward said flipper so that the latter can directly propel a ball on said first playfield via said path onto said second playfield or a ball may travel from second playfield to said first playfield, said second end disposed on said second playfield so that a ball may descend to said first playfield or ascend to said second playfield; (c) another flipper disposed on said second playfield adjacent said second open end of the path for propelling a ball on said second playfield away from said path, said another flipper selectively operable by the player to prevent a ball on the second playfield from entering said path and descending to the first playfield thereby providing the player with the opportunity to keep a ball in play on the second playfield; and (d) a plunger adjacent the lower end of said first playfield, a track means extending from the free end of said plunger for guiding a ball propelled by the plunger, an arcuate channel having a ball entrance disposed below the surface of the second playfield to receive a ball from the track means, and a ball disposed above the level of said second playfield so that balls enter the second playfield traveling in a direction 180 degrees opposite from the direction of travel of the balls just prior to entering the arcuate channel and substantially at the level of the second playfield.
