Abstract: A three-ball pool rack apparatus includes three straight wall portions and three curved corner portions connected between adjacent straight wall portions. The straight wall portions and the curved corner portions define a ball-reception space, and the ball-reception space is of a size which is large enough to retain a maximum of three standard size pool balls. The straight wall portions and the curved corner portions form an equilateral triangular formation. The straight wall portions and the curved corner portions extend perpendicularly upward from a pool table surface when placed thereon. Preferably, a lip extends outward horizontally from top portions of the straight wall portions and the curved corner portions. A finger-reception gap is provided in the ball-reception space when three object balls are contained in the ball-reception space.
