Snooker Scoreboard

How to use it

1. Type the names of the two players at the top of the page, and the frames needed to win the match.
2. After each shot, press Red (1) or the colour that was potted, for the player whose turn it is. The page shows whose turn comes next.
3. When a foul is made, choose its Points for the foul (4 to 7) and press Foul: the other player scores the points and plays next. Press Miss when a visit pots nothing.
4. When the frame is over, press Start next frame and choose who breaks. Undo takes back the last shot.

Balls, points and the frame

The fifteen reds are each worth 1 point. The colours are worth yellow 2, green 3, brown 4, blue 5, pink 6 and black 7. Reds and colours are potted alternately while reds remain; after the last red a colour is potted, and then the colours are potted in ascending order of value (WPBSA Section 3 Rule 1(a) and (b)).

A colour potted while reds remain goes back on the table, so it stays in play. The points left on the table are the highest that can still be scored: each red with a black, then the colours still to be potted. A frame starts with 147 points left, the maximum break. The winner of a frame is the player with the higher score (Section 3 Rule 1(f)).

Points left = 8 × reds left + 7 for the colour due after the last red (if any) + the value of the colours not yet potted in order

At the start: 15 × 8 + 27 = 147

Fouls, claims and snookers required

A foul gives the other player four penalty points, or the value of the ball on or of a higher-value ball concerned if that is more (Section 3 Rule 11). With Black the only ball left, the first pot or foul ends the frame unless the scores are equal (Section 3 Rule 4(a)).

The striker may claim the frame when Black is the only ball left and the lead is more than seven points (Section 2 Rule 5(d)). The rules do not define "snookers required". The count on this page is the one scoreboards show: the points the trailing player needs to win, less the points left, divided by four, rounded up. It is an explanation of the rules' arithmetic, not a rule.

Points needed to win = lead + 1
Snookers required = (points needed − points left) ÷ 4, rounded up, when the points left cannot cover the lead

Example: lead 70 to 20, only the black (7) left: (51 − 7) ÷ 4 = 11

What the page does not play

• The re-spotted black when the scores are level after the last ball (Section 3 Rule 4(b)); the page shows the level frame and leaves the decision to the referee.
• Penalties that do not affect the order of play, the referee's decisions, the shot clock, and the choice of who plays first in a re-spotted black.
• Which balls are on, the position of the cue ball and the pots of a shot. The page records the points, not the table.
