Tennis tiebreak rules, explained point by point

A tennis tiebreak is played when a set reaches 6-6. First to seven points wins it, but only with a two-point margin — at 6-6 in the tiebreak, play continues until someone leads by two. The set is recorded 7-6.

When a tiebreak starts

Games accumulate normally until the set stands at six games all. The tiebreak then replaces what would have been the thirteenth game, and whoever wins it takes the set 7-6.

Not every format has one. Advantage sets — win by two games, no ceiling — survive in some club, league, and team formats, and they're why Isner and Mahut once reached 70-68 in the fifth at Wimbledon in 2010. If the ladder from point to set is still fuzzy, how many sets in a tennis match covers it.

Who serves in a tennis tiebreak: one point, then two

The player whose turn it is to serve serves the first point. At 6-6 each player has served six games, so that's whoever opened the set with game one.

That first point is a single point, delivered from the deuce court (the right side). After it, service alternates every two points for the rest of the tiebreak. Each two-point turn begins from the ad court (the left side) and finishes from the deuce court.

The pattern in short: one, then twos. Point 1 goes to the first server. Points 2 and 3 go to the opponent. Points 4 and 5 come back. Points 6 and 7 go across again, and so on for as long as the tiebreak runs.

In doubles the same rotation applies, and each team keeps the serving order it used during the set. Partners don't swap turns because a tiebreak started.

A 7-5 tiebreak, point by point

Here is a full tiebreak with A serving first. The score column reads A's points first.

Point	Server	Serving from	Score	Notes
1	A	Deuce court	1-0	One point only, then serve passes
2	B	Ad court	1-1
3	B	Deuce court	2-1	A wins it against serve — a mini-break
4	A	Ad court	3-1
5	A	Deuce court	4-1
6	B	Ad court	4-2	Change ends after this point
7	B	Deuce court	4-3
8	A	Ad court	4-4	B mini-breaks back
9	A	Deuce court	5-4
10	B	Ad court	6-4	A leads with two set points
11	B	Deuce court	6-5
12	A	Ad court	7-5	Set to A, 7-6

Serve order and the six-point end change are the two things players lose track of mid-tiebreak, usually while arguing about the score. Tennis Scoreboard is a tennis scoreboard app for iPhone and Apple Watch that tracks match scores, so the count sits on your wrist instead of in three people's memories.

Each player served six of the twelve points, and that balance is the whole reason for the one-then-twos rotation. The only end change came after point six, at 4-2.

Changing ends every six points

Ends change after every six points played — at 6, 12, 18 — no matter who leads. Watch for scores that add up to six: 4-2, 3-3, 5-1, 6-0. There's no sit-down at these changeovers; you swap ends and keep playing.

Two further details catch people out. The tiebreak counts as a game, so a 7-6 set contains thirteen games, an odd number, and the players change ends again once it finishes. And whoever served the first point of the tiebreak receives first in the next set, so the service order carries over rather than resetting.

Seven-point set tiebreak vs ten-point match tiebreak

Two different things share the word tiebreak, and mixing them up is how on-court arguments start.

A set tiebreak is the seven-point version above. It decides one set, at 6-6, and the match continues.

A match tiebreak — also called a super tiebreak or championship tiebreak — is played to ten points in place of a full deciding set: at one set all in a best-of-three, or two sets all in a best-of-five. Everything else is identical — two-point margin, the one-then-twos serve rotation, ends after every six points. That last part is the common error: ends change after the sixth point and again after the twelfth, not halfway at five. It's scored as a set of 1-0, usually written in brackets: 6-4, 4-6, [10-8].

Tour-level doubles is where you'll meet it most often, since ATP and WTA doubles replace the deciding set with a ten-point match tiebreak. It's common in mixed doubles too, and in plenty of league and club formats.

Wimbledon tiebreak rules and the rest of the majors

Since 2022 all four Grand Slams have used the same deciding-set format: at 6-6 in the final set, a ten-point tiebreak settles the match. It was the first time all four agreed on one rule for the deciding set.

What each did before:

• Australian Open — ten-point tiebreak at 6-6 in the final set, from 2019.
• Wimbledon — seven-point tiebreak, but only at 12-12, from 2019.
• US Open — seven-point tiebreak at 6-6, for decades the only major with a standard final-set tiebreak.
• Roland-Garros — no final-set tiebreak at all; the deciding set ran as an advantage set.

Everywhere else in a Grand Slam draw the ordinary seven-point tiebreak applies at 6-6, and the same holds on the ATP and WTA tours, where best-of-three matches use a seven-point tiebreak in every set.

Calling the tiebreak score

Tiebreak points are counted in plain numbers — one, two, three — not 15, 30, 40. The server's score is called first, as in a normal game, so the server trailing 2-4 calls it "two-four." At six points each the call is "six all," never deuce; deuce and advantage belong to ordinary games, and the tennis score after deuce runs on a different ladder entirely.

Winning a point on your opponent's serve is a mini-break, and it's the currency of a tiebreak: hold every point on your own serve and one mini-break is enough to win it. The rest of the vocabulary sits in the tennis scoring rules.

FAQ

How does a tiebreaker work in tennis?

At 6-6 in a set, players play a tiebreak instead of a thirteenth game. First to seven points wins, provided the lead is two; otherwise play continues until someone is two clear. The opening server serves one point, service then alternates every two points, and ends change after every six points.

What is a tiebreak in tennis compared to a normal game?

A normal game is scored 15, 30, 40, game, and one player serves it throughout. A tiebreak is scored in plain numbers, both players serve inside it, and the ends change midway. It occupies one slot in the set score but decides the whole set.

Who serves first in a tennis tiebreak?

Whoever's turn it was to serve the next game, which means whoever served game one of the set, since both players have served six games at 6-6. They serve exactly one point from the deuce court, and then the opponent serves two.

Do you change ends at five points in a ten-point tiebreak?

No. Ends change after every six points in both the seven-point and ten-point versions, so a match tiebreak changes after the sixth point and again after the twelfth. Five is a widespread misconception.

What are the Wimbledon tiebreak rules in the final set?

Wimbledon plays a ten-point tiebreak at 6-6 in the deciding set, matching the other three Grand Slams since 2022. Before that it used a seven-point tiebreak at 12-12, and until 2019 the final set had no tiebreak at all.
