TournamentRotation pool · nine ballsPool

Objective and format

First to legally pot ball 9. Only nine balls on the table; play strictly by number — first 1, then 2, and so on.

You can win by combination: if cue ball first contacts the lowest number on the table, the 9 can go in "on the chain".

  • Tournament format: to 7, 9, or 11 wins — race to N frames.
  • Format is listed on the event card on billiard.guru.

Setup and break

  • Balls 1–9 in a diamond: 1 on foot spot, 9 in center; others — by lot or template.
  • Power break: first contact — ball 1; after shot minimum 4 balls to cushion or any ball in pocket.
  • Cue ball must cross head string or return to kitchen / touch cushion — per pool association regulations.
  • Illegal break — ball in hand to opponent.

Play

  • "Ball on" — lowest number on the table; cue ball must contact it first.
  • Any ball counts if contact order is correct; 9 can be winning at any time.
  • Shot from wrong half of table — foul (cue ball crossed head string incorrectly).
  • After foul — ball in hand; opponent may place cue ball anywhere (in tournaments — often behind head string only).

Push-out after break

After the break opponent may declare "push-out" — a shot without obligation to drive a ball to cushion or pot.

  • Push-out allowed only immediately after break and only for incoming player.
  • Opponent decides: shoot themselves or return the shot to breaker.
  • Push-out rules depend on tournament regulations — confirm before the match.

Fouls

  • Did not first contact "ball on".
  • Cue ball in pocket, ball off table, double hit, push shot.
  • Shot when only 9 remains without cushion contact (if not potted).
  • Three consecutive fouls on one visit — loss of frame (pool association tournament rule).

Historical note: nine-ball

Nine-ball is the tournament "rotation" discipline: balls 1–9, win on the 9. Symbol of modern professional pool and televised series since the 1970s.

Origins

Nine-ball originated in the USA in the early 20th century as a fast game on nine balls. The rule "first contact the lowest number on the table" and winning by combination on the 9 made the discipline spectacular.

From the 1970s — backbone of televised pool: short frames, power break, pace. WPA World Nine-ball Championship and Matchroom series brought the discipline to a global level.

The Philippines produced nine-ball legends (Parreño, Bustamante, Chi); from the 2000s China and Taiwan are centers of prize money and academies.

Key rules and differences

  • Cue ball must first contact the lowest number on the table.
  • You can win by combination: the 9 goes "on the chain" after a legal hit.
  • "Ball on": cue ball and object ball on different halves of the table (head string).
  • Three consecutive fouls — loss of frame (WPA tournament rule).
  • Cue ball in pocket — foul; ball in hand to opponent.

Television and the professional tour

In Russia nine-ball is more popular than straight pool; tournaments on billiard.guru often use this format.

This is a short guide. The exact regulations are in the tournament description on billiard.guru or from the organizer. Official event rules take precedence.
