Abstract: A system for racking billiard balls of a given diameter on a playing surface, the system comprises a billiard ball gauge, a pro-rack and recreational-rack. The pro-rack and the recreational-rack each include a frame having an interior opening with an internal periphery. The internal periphery has segmented circular portions. Each rack is a top racking rack used to position and hold billiard balls in close contact when the rack rests upon the top of the balls. The billiard ball gauge determines which rack is best for the given size of the balls.
