The Official Rules of the Game
Play with confidence. The American CueSports Alliance strictly recognizes and enforces the global standard of play.
Global Consistency. Local Competition.
To provide the fairest and most professional playing environment, the American CueSports Alliance (ACS) utilizes the World Standardized Rules established by the World Pool-Billiard Association (WPA).
By enforcing these rules across all sanctioned leagues and national championships, we ensure that our players are developing skills that translate to the highest levels of global competition. Whether you are playing 8-Ball, 9-Ball, or 10-Ball, knowing the rules is your first step toward victory.
