This invention relates to a rack for aligning billiard balls at the start of a game. The rack is a flat, rigid, plastic frame member having legs which maintain the frame a desired distance above the playing surface. The periphery of the inner opening is constructed having segmented circular indentations which mate with the billiard balls. The inner opening is the shape of an equilateral triangle having sides which are equal to five times the major diameter of the billiard balls and having twelve indentations therein, thereby accommodating fifteen billiard balls in the standard equilateral triangular configuration.
