 The Billiard Congress of America (BCA) publishes a long-standardized set of rules for the game.At the start of kelly pool, the numbered markers (commonly called or pills, and sometimes tally balls or shake balls) are placed in a specially made, narrow-necked container (called variously a , pea bottle, pill bottle, kelly bottle, tally bottle or shake bottle) which is shaken to randomly distribute them.Each player then draws a numbered pea from the bottle.
