Kelly pool also known as pea pool , pill pool , keeley , the keilley game , and killy  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 15 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. In the simpler form, the object of play starts and ends with the goal of pocketing one's secret ball.
