Tennis scoring: games, sets and the tiebreak

How ScoreCastr counts a tennis match: points to games with deuce and advantage, games to sets, the tiebreak at 6-6 and the end of the match.

Updated 4 min readFree

When you click +1 for a point, ScoreCastr decides what that point means: a new score in the game, a game won, a set won, a tiebreak or the end of the match. Knowing the rules it follows helps you trust the scorebug and fix it fast when a point goes to the wrong player. This guide explains them.

Short versionScoreCastr plays standard advantage tennis: deuce at 40-40, then advantage. Sets go to six games by two, with a tiebreak to seven points by two at 6-6 in every set. The match ends when a player wins two sets of three (or one of one, or three of five).

Points in a game

Each +1 moves the player along: 0, 15, 30, 40. From 40, the next point wins the game, unless the other player is also on 40.

Deuce and advantage: at 40-40, the next point gives that player the advantage. The dashboard shows ADV; the Apex and Primetime scorebugs show AD.

  • If the player with the advantage wins the next point, they win the game.
  • If the other player wins it, the score goes back to 40-40.

There's no limit on how many times a game goes back to deuce. ScoreCastr always plays advantage games; there's no no-ad (deciding point) setting, so for a no-ad match, click +1 twice for the player who wins the deciding point at 40-40. That wins the game the normal way, with the serve switch, though that player's points won counts one extra.

When a game is won, the points go back to 0-0, the winner's games go up by one, and the serve switches.

Games in a set

A set goes to six games, won by two:

Games What happens
6-0 to 6-4 Set won
6-5 Play on
7-5 Set won
6-6 Tiebreak

When a set is won, its score is saved (the scorebug shows each finished set), the games go back to 0-0 and the winner's sets go up by one.

The tiebreak

At 6-6, ScoreCastr starts a tiebreak in any set, including the last one.

  1. TIE-BREAK lights up under ADDITIONAL DISPLAYS, and the Classic scorebug shows a TB tag (Apex and Primetime show TIEBREAK).
  2. The regular +1 and -1 buttons turn grey. Use the +1 and -1 in the TIE-BREAK panel that appears.
  3. Tiebreak points count 1, 2, 3 and so on. The first player to seven, at least two ahead, wins.

The set is saved as 7-6, and the scorebug shows both players' tiebreak points next to it. The serve during and after the tiebreak is handled for you; see Tennis serve tracking.

Sets in a match

You choose the match length when you create it, with Best of Sets:

Best of Sets to win
1 Set 1
3 Sets 2
5 Sets 3

When a player reaches that number, the match is over: (Match Complete) appears next to the card title, the scoring buttons lock and the scorebug shows MATCH COMPLETE and the winner. Apex and Primetime give the winner a trophy and dim the other row.

Points won

Every +1 also counts toward that player's points won for the match, and -1 takes one off, including tiebreak points. With the Starter plan you'll see the totals and percentages under Points Won in the sidebar's Match Statistics.

Fix a wrong score

Most mistakes are one point given to the wrong player:

  • Within a game: click -1 for the wrong player and +1 for the right one. From ADV, -1 goes back to 40.
  • Set a point score directly: use the 0, 15, 30, 40, ADV row for that player. Clicking 40 when the other player has ADV puts the game back to 40-40.
  • A game went to the wrong player: -1 can't undo a finished game. Use GAMES -1 for the wrong player and +1 for the right one, then set the points with the direct buttons.
  • A set is wrong: use the SETS -1 and +1 buttons.

The direct buttons only set the number you choose. They don't finish a game, set or match by themselves, and they don't change points won. After a fix, carry on with +1 and the counting picks up from there.

Watch outFixing games with GAMES +1 doesn't trigger a set win or the tiebreak. If you correct a set to 6-4, also correct SETS and set GAMES back to 0 for each player.

Checklist

  • Best of Sets matches the event's format
  • Every point scored with +1, not the direct buttons
  • Tiebreak points scored in the TIE-BREAK panel
  • Deciding points at 40-40 scored with two clicks, if your event plays no-ad
  • Sets and games checked after any fix
