Learn the Basic Rules and Decisions of Nine-Ball

Rack and start the game

Under the current World Pool Association rules effective September 15, 2025, the balls are racked as tightly as possible in a diamond, with the 1 at the apex and the 9 in the middle on the foot spot. Balls 2 through 8 fill the remaining seven positions without a purposeful pattern.

The breaker starts with the cue ball above the head string. Events may add equipment procedures or a break box, so the event sheet controls when it differs from casual house rules.

Hit the lowest-numbered ball first

On every standard shot, the cue ball must first contact the lowest-numbered ball remaining. The object ball that is pocketed does not need to be that ball if the shot is otherwise legal.

After contact, a ball must be pocketed or at least one ball must reach a cushion unless a special rule such as the push-out applies. A player who legally pockets a ball continues.

Know the legal break requirement

The current WPA nine-ball break requires the one to be contacted first. If no ball is pocketed, at least four object balls must be driven to one or more rails; WPA Regulation 16 also governs how many balls must cross the head string in applicable play.

A scratch or illegal break changes possession under the rules. Confirm the exact event procedure before the match instead of relying on a local custom.

Use the push-out deliberately

Immediately after a legal break, the player entitled to the next shot may announce a push-out, whether that is the breaker continuing or the opponent. For that shot, the usual wrong-ball and no-rail foul requirements are suspended, but other fouls still apply and pocketing the nine does not win the rack.

After the push-out, the opponent chooses who shoots next. Place the cue ball where both choices are uncomfortable for the opponent but playable for you; a push-out that offers an easy shot is not strategic.

Handle fouls and the nine ball

A standard foul gives the opponent ball in hand anywhere on the table. Common fouls include scratching, hitting the wrong ball first and failing to drive a ball to a cushion after contact when nothing is pocketed.

Three consecutive fouls can lose the rack after the required warning under WPA rules. A legally pocketed nine normally wins, but exceptions such as a push-out or foul return it according to the rules.

Plan one ball beyond the shot

• Identify the lowest-numbered ball before getting down.
• Choose a legal pocket or safety with a clear cue-ball route.
• Plan position on the next lowest-numbered ball.
• Prefer broad landing zones over exact dots.
• Recheck combinations: the lowest ball must still be struck first.
• Use the published event rules whenever local practice differs.
