A pinball repair sleeve for repairing the damage bottom surface of a pinball trough has a first section having a flat, smooth upper surface. Extending from the first section are two elongated arm components forming a V-configuration. The inward edges of the upper surfaces of the arm components are tapered down to facilitate the movement of pinballs down the arm components of the sleeve. The inward edges of the bottom surfaces of the arm components are tapered up to facilitate placement of the sleeve onto the corresponding V-shaped groove of the trough to be repaired. A resilient bracket hook member is provided beneath the first section to secure the sleeve to the trough.
