How does a 10-point match tiebreak work?
It replaces the deciding set. First to ten points wins the match, and you have to be two clear, so it can finish 10-8, 12-10 or further. Serve rotates after one point and then two at a time, and you change ends every six points.
When you play one
At one set all in a best of three, or two sets all in a best of five. Instead of playing a third or fifth set you play a single tiebreak game, and it decides the match. Nothing before it changes: the sets already won stay on the board and go into the final score.
It has to be agreed first. Appendix VI says these methods may be used, so a match tiebreak is what the league sheet or the event says you play, never something the rules impose at one set all.
Start a third set by mistake and Rule 27h has an answer: correct it immediately if only one point has been played, otherwise carry on until somebody wins three games and the set with it, or until 2-2, when the match tiebreak is played instead.
Who serves
The order of service simply carries on from the set that just ended. Whoever was next up serves the first point. The other side then serves two, and it alternates in twos until somebody is two clear at ten or more.
There is a 120-second set break before it starts, the same as between sets, and the balls are not changed for it even if a ball change was due.
Change of ends
Every six points, counted on the total of both scores: at 4-2, at 7-5, at 9-9. Neither score on its own tells you anything.
You swap without sitting down. Rule 29a makes play continuous during a tiebreak, so the ninety seconds you get at an ordinary changeover is not on offer here.
Appendix VI carries an approved alternative, after the first point and then every four points, which some events run instead. Six is the main rule and what you will be playing unless the sheet says otherwise.
In doubles
A pair may change their serving and receiving order for the match tiebreak, exactly as they could at the start of a new set. If your stronger server has been serving second all match, this is the moment to put them first. Inside the tiebreak the rotation then runs in that order and stays in it.
How it gets written down
By convention, like a set and in brackets: 6-4 3-6 [10-7]. The match reads as three sets even though the third one was a single game.
In the rule book
ITF Rules of Tennis, Appendix VI.4, Match Tie-break (10 points):
When the score in a match is one set all, or two sets all in best of five sets matches, one tie-break game may be played to decide the match. This tie-break game replaces the deciding final set.
The first player/team to win ten points shall win the match tie-break and the match provided there is a margin of two points over the opponent(s). If necessary, the match tie-break game shall continue until this margin is achieved.
The note printed under it is the part clubs miss: the original order of service continues, and in doubles the order of serving and receiving within the team may be altered as at the beginning of a set.
Common follow-ups
Is a match tiebreak the same as a 10-point tiebreak at 6-6?
No, and this is the one clubs mix up. A match tiebreak replaces the deciding set and starts the moment the set before it ends. A ten-point tiebreak at six games all is played inside the deciding set, only if the set gets that far, and the set is written down as the 7-6 it is. That second one is Appendix VI.5, the final-set tiebreak, and it is what all four Grand Slams have played in a deciding set since 2022. That is those four events’ own rule book rather than the ITF’s.
What else is it called?
Match tiebreak in the rule book. Championship tiebreak, super tiebreak, or “third set is a breaker” on a league sheet. Same game.
Do you have to win by two?
Yes. Ten points is the target and two points is the margin, so at 9-9 you keep going until one side leads by two.
Does it count as a set for league points?
That one is not in the rules of tennis, because it is not a rules question. The ITF book says how the match is scored; how your division awards points for it is your league’s to decide. Ask your captain before the match rather than in the car park after it.
Pick it as the deciding set in Luasc and the watch starts the tiebreak the moment the second set ends, hands the serve to whoever was next, and offers a doubles pair their choice of server before the first point. The formats it plays.
