Mid-Field Ball Return Gates

A subtype of Ball Return Gates positioned in the central area of the playfield rather than at the outlane boundaries. Mid-field ball return gates use the same one-way metal flap mechanism as their outlane counterparts but serve a different design purpose: they partition the playfield into distinct zones, allowing the ball to flow from an upper region to a lower one while preventing it from rolling back. Designers on Electromechanical machines from Gottlieb, Bally, and Williams used mid-field gates to create one-way lanes, guide ball traffic around obstacles, and enforce directional flow through scoring sequences.
