9-Ball

9-Ball, governed by the Billiard Congress of America (BCA), is a pocket billiards game where players must hit the lowest-numbered ball on the table first on every shot. The goal is to legally pocket the 9-ball at any time to win the rack. 

Objective and gameplay

• Winning: A player wins the rack by legally pocketing the 9-ball. This can be done directly or via a combination shot, as long as the lowest-numbered ball is struck first.

• Sequential hitting: The cue ball must always contact the lowest-numbered object ball on the table first. However, other balls do not have to be pocketed in numerical order.

• Continuing your turn: If you legally pocket any ball, you continue shooting. Your turn, or "inning," ends when you miss a shot, commit a foul, or win the game by pocketing the 9-ball.

• Shot calling: Unlike some other billiards games, no shots need to be called.
