Kelly pool is a pool game played on a standard pool table using a standard set of 16 pool balls. Gameplay involves players each drawing one of 16 numbered markers called peas or pills at random from a shake bottle, which assigns to them the correspondingly numbered pool ball, kept secret from their opponents, but which they must pocket to win the game. Kelly pool is a rotation game, which means that players must contact the lowest numbered object ball on each shot first until the opportunity to pocket their own is presented. If a player draws the number 16, this player is assigned the cue ball. In order to pocket the cue ball, the player must contact the lowest ball first and in the same shot, pocket the cue ball. However, the game is commonly played by removing the pea numbered 16 and playing with the basic 15 numbered balls and corresponding peas. Two rule variants are set forth under rules promulgated by the Billiard Congress of America (BCA). In the simpler form, the object of play starts and ends with the goal of pocketing one's secret ball. In the second, in addition to the goal of pocketing one's secret ball, points are scored in various ways. In the instance where pills are unavailable, a cloth may be used to cover the balls, which are then chosen blindly, recorded, and replaced for play.
