Classic snooker

Score more points than the opponent in a frame. Frame won when the score cannot be caught, or after the last ball (black) is potted.

Match — to N frames (e.g. best of 3, 5, or 9) — per tournament regulations on billiard.guru.

• Maximum points in one break with 15 reds — 147 (maximum break).
• Break — while you pot without a miss or foul.

• 15 reds — tight triangle on the pink (or behind it); colors on spots: yellow at D line, green, brown, blue, pink, black.
• Cue ball — in the D-zone (semicircle at the baulk line).
• First break — by lot; break alternates by frame.

• Red — 1, yellow — 2, green — 3, brown — 4, blue — 5, pink — 6, black — 7.
• While reds remain: pot red, then any color; color returns to spot, red stays in pocket.
• When reds are gone — colors strictly in ascending points to black.
• After the last red, usually blue, then pink, black — in order.

First shot — from the D-zone. Cue ball must first contact a red; after the shot at least one ball — in a pocket or to a cushion.

• Illegal break — 4-point penalty to opponent; opponent accepts or asks for re-break.
• Cue ball in pocket on break — 4 or 7 penalty (by highest ball in play) + opponent's turn.
• Power break less common than pool — leaving the cue ball for the break matters more.

• After red — any color; if color not potted, it returns to spot.
• Potted red — must play a color; potted color — red again.
• Tactics: alternate "easy" colors (black, pink) with reds to build a break.
• If no direct shot at red — snooker or miss per rules.

• After last red — colors in order: yellow → green → brown → blue → pink → black.
• Each color potted once; not returned to spot.
• Black at the end — decisive; if tied before it, re-spot possible per regulations.
• Frame ends when black is potted or opponent concedes.

Snooker — when a direct shot at ball on is impossible: cue ball blocked by other balls or angle does not work.

• Player may ask referee to check snooker or play a kick with declaration.
• Miss on snooker — penalty points (minimum 4, or value of ball on).
• Free ball: after foul snooker, any ball may be nominated as red or ball on — per regulations.
• Tactics: leave opponent a difficult snooker — key to snooker defence.

• Penalty — minimum 4 points, or value of ball on, or 7 — highest of them.
• Wrong ball first contact, wrong red/color order.
• Cue ball in pocket, ball off table — penalty + opponent's turn (often from D or "ball in hand" in D).
• Three consecutive misses on snooker — frame loss (tournament rule).
• Double hit, push shot, touching ball before stroke.

Match consists of frames; winner is whoever wins more frames (best of 3, 5, 9, etc.).

• Break between frames; in long matches — interval.
• Conceding frame or match — per etiquette and regulations.
• On billiard.guru format and shot time limit — in tournament card.
