Upper Right Kickback Lanes
Upper right kickback lanes are Right Kickback Lanes placed high on the playfield, above the pop bumpers rather than beside the flippers, where they return a ball that has climbed the right flank back into the upper field.
The arrangement belongs to the Electromechanical years and the solid-state machines that immediately followed them: Bally fitted it to Mariner / Sea Ray (1971), and Williams, Sonic and Zaccaria all used it through the middle 1970s.
