How does serving rotate in a tiebreak?

The player due to serve plays the first point only, from the deuce court. After that, service alternates every two points, with each new server starting from the advantage court then the deuce court. This 1-2-2-2 pattern continues until the tiebreak ends.

What score wins a standard tiebreak?

The first player to reach seven points wins, provided they lead by at least two. If the score reaches six-all, play continues until one player is two points clear, so scores like 8-6 or 10-8 are common in tight tiebreaks.

When do players change ends in a tiebreak?

Players change ends after every six points played, that is at 6 total points, 12 total points, and so on. The tracker flags these moments so you do not lose track during a long tiebreak.

Does this handle a match tiebreak to ten?

Yes. Switch the target to ten points and the same two-point margin and 1-2-2-2 serving rules apply, with end changes still every six points. The match tiebreak, used in place of a deciding set, is otherwise identical in structure.

Who serves the first game of the next set?

Whoever received serve in the first point of the tiebreak serves the first game of the following set. The tracker shows the first server, so you can hand the next set's opening service to their opponent as the rules require.

A tiebreak’s serving rotation trips up casual players and even umpires under pressure. This interactive tracker keeps the score, applies the 1-2-2-2 serving pattern automatically, signals when to change ends, and declares the winner at seven points by a two-point margin — or ten for a match tiebreak.

How it works

Let the first server be player A. The serving rule by total points played n (zero-based point about to be played) is:

point 1 (n = 0)         → A serves
points 2–3 (n = 1,2)    → B serves
points 4–5 (n = 3,4)    → A serves
points 6–7 (n = 5,6)    → B serves
…alternating every 2 points thereafter

A compact formula gives the current server: serve flips every two points after the first, so the server is A when floor((n + 1) / 2) is even and B when it is odd. The tiebreak ends when a player reaches the target (7, or 10 for a match tiebreak) with at least a two-point lead. Ends change every six total points.

Example and tips

From 0-0 with A to serve, A serves point 1; B then serves points 2 and 3; A serves points 4 and 5; and so on. At 6-6 nobody has won yet — play must continue until someone leads by two, so 8-6 or 9-7 are valid finishes. Remember that the player who received the first tiebreak point serves the opening game of the next set, which is the most commonly forgotten rule and the one this tracker makes obvious by showing the first server.
