A bowling ball return gate operates in response to a ball tripping a lever for releasing the gate from its closed position for permitting the ball to be delivered to a center ball return shared by adjacent alleys. The gate operates in combination with an oscillating paddle positioned between kickbacks of the adjacent alleys wherein the paddle is moved from opening to adjacent alley opening of each adjacent kickbacks for alternately receiving a ball through the openings from its respective pit area while clearing any pins within the openings. The paddle moves within a T-tube section which is transverse to a longitudinal tube section housing the gate. The paddle is continuously moved between openings of the adjacent alley kickbacks for clearing pins on a continuous basis. The tripping lever holding the gate in its closed position can only be tripped by a ball entering the T-tube longitudinal section.
