What is Snooker?

Snooker is a cue sport played on a 12 ft × 6 ft (365 × 183 cm) baize-covered table with six pockets — one at each corner and one in the middle of each long side. Play uses 22 balls: 15 red (1 pt each), yellow (2), green (3), brown (4), blue (5), pink (6), black (7), and a white cue ball. Players alternately pot a red then a colour; potted reds stay off the table while colours are respotted after each pot until only 6 colours remain, which are then potted in order yellow to black. A break is a run of consecutive pots by one player. The maximum break is 147 (15 reds each followed by black + colours yellow-to-black). Snooker was invented in 1875 by British Army officers stationed in Jabalpur, India (credited to Sir Neville Chamberlain), and became professional in the UK in 1927 with the World Championship (Joe Davis champion 1927-46, 15× in a row). The modern era is dominated by Ronnie O'Sullivan (7× World Champion), Stephen Hendry (7×), and Ray Reardon / Steve Davis (6× each).

How it works

Objective

Win each frame by scoring more points than opponent; win the match by winning majority of frames.

Match structure

Frame: alternate pot red (1pt) + colour (2-7pts, respotted); when reds gone, pot colours in order yellow→black. Match = best of N frames (5, 7, 11, 17, 19, 25, 33, 35 depending on tournament).

Rules

Basic rules

  • Red then colour

    Player pots red (1pt), then nominates and pots any colour (2-7 pts, respotted); alternate.

  • Order at end of reds

    After all 15 reds potted, pot colours in order yellow(2)-green(3)-brown(4)-blue(5)-pink(6)-black(7).

  • Foul = penalty

    Fouls give opponent 4-7 points (minimum 4, or value of ball fouled if higher).

  • Common fouls

    Miss ball on, pot wrong ball, cue ball in-off, hit ball on with wrong first contact, cue ball off table.

  • Break (run of pots)

    Highest break in one visit is 147 (perfect break: 15 reds + 15 blacks + all colours).

  • Frame ends

    When all balls off table or one player concedes; winner scores more points.

Advanced rules

  • Snooker (tactical)

    Positioning cue ball so opponent cannot see legal ball — forces foul or safety.

  • Free ball

    If snookered by opponent's foul, nominate any colour as free ball.

  • Miss rule

    Referee calls 'miss' if player fails to hit ball on with reasonable attempt; opponent can request replay.

  • Break-building tactics

    Position cue ball for next shot; aim to keep on high-value colours (blue/pink/black) for high breaks.

  • Safety play

    Defensive shots leaving opponent snookered or with no easy pot.

  • Century break

    Break of 100+ points — hallmark of top players; Ronnie O'Sullivan has 1,200+ centuries.

Scoring

Each ball has assigned point value 1-7; player with more points at end of frame wins.

Strategies

  • Prepare next shot

    Position cue ball for easy next pot before playing current shot.

  • Chain colours efficiently

    Keep on high-value pink/black between reds for maximum break potential.

  • Safety when no easy pot

    Don't force low-percentage pots; play safety (defensive) instead.

  • Snooker opponent

    When ball on is difficult, snooker opponent — hide cue ball behind other balls.

  • Manage cue ball speed
