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.

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.

Walked example

From 0-0 with A to serve: A serves point 1 (score 1-0 to A), then B serves points 2 and 3. If each player wins one of those, the score is 2-1. A serves points 4 and 5; if A wins both, the score reaches 4-1. B serves points 6 and 7, A serves 8 and 9, B serves 10 and 11, and so on.

After six total points the players cross ends — the tracker highlights this moment. At a score of 6-6 neither player has won yet; play continues until someone leads by two, so 8-6 or 9-7 are valid finishes. A score of 7-6 is impossible in a standard tiebreak (the player at 7 wins the moment they lead by two, not one).

The overlooked rule about the next set

After the tiebreak, the player who received the very first point of the tiebreak serves the opening game of the next set. In practice: if A served point 1, B served from point 2 onward — so B is the one who received first, and B opens the next set. This is the rule most casually forgotten in recreational play, and the reason this tracker prominently displays who served first.
