The cue ball angle determinator is a small device to be used while playing the game games of pool, billiards or snooker. The purpose of the invention is to determine the exact spot on the rail cushion to strike in order to make an accurate path of travel of the cue ball. This has been accomplished with the cue ball angle determinator by means of adjustable indicators to direct beams of light to the intended balls of action and a marker to mark the point of impact on the rail cushion after this has been established.
