Abstract
A method and apparatus for aiming billiard balls comprising an object ball with a surface coated with an array of colored dots. Adjacent dots are dissimilarly colored to aid in their distinguishment. A desired trajectory is aimed for by first sighting the object ball from a direction opposite a target and selecting a contact dot disposed collinear with that trajectory and furthest from that target. A cue ball or other striking means is then aimed to strike the object ball at the contact dot.
