How Tiebreaks Work

A tiebreak is a special game played to decide a set that has reached 6 games all (6–6). Instead of playing more standard games, both players compete in a single tiebreak game using numeric scoring (1, 2, 3… instead of 15/30/40). The winner of the tiebreak wins the set 7–6.

Tiebreaks prevent sets from going on indefinitely and are used at nearly every level of competitive tennis, including USTA league play.

• Regular tiebreak: first to reach 7 points with at least a 2-point lead
• Match tiebreak: first to reach 10 points with at least a 2-point lead
• If the score reaches 6–6 (regular) or 9–9 (match tiebreak), play continues until one player leads by 2

There is no cap — if both players keep trading points at 6–6 or 9–9, the tiebreak goes on until the 2-point margin is reached.

The player whose turn it is to serve based on the normal service rotation starts the tiebreak. In other words, the player who would have served the 13th game (had normal games continued) serves first.

• The first server serves 1 point from the right (deuce) side
• Service then switches to the opponent, who serves 2 points
• After that, service alternates every 2 points for the rest of the tiebreak

A useful way to remember: 1, then 2, then 2, then 2…

• Players change ends when the total points played reaches 1, 5, 9, 13… — i.e., after the 1st point, then every 4 points after that
• The changeover is taken without a rest — players walk directly to the other end
• At the conclusion of the tiebreak, players take a normal 90-second rest before the next set begins

Serving sides rotate based on the total number of points played in the tiebreak — not per individual server.

• Odd-numbered points (1, 3, 5, 7…): serve from the left (ad) side
• Even-numbered points (2, 4, 6, 8…): serve from the right (deuce) side

Since the first serve is point 1 (odd), it is served from the right side. Wait — point 1 is the first point, so it's odd, but the pattern starts from the deuce court. The simplest way to remember: the first point is served from the deuce (right) court, then serving side alternates with each point.

The player who served first in the tiebreak receives serve at the start of the next set. This is because they effectively used their service turn for the tiebreak game.

A quick check: if you opened the tiebreak serving, your opponent serves the first game of the next set.

Example: 6–4, 3–6, [10–7]

• Player A won the 1st set 6–4
• Player B won the 2nd set 6–3
• A 10-point match tiebreak was played in lieu of a 3rd set — Player A won 10–7
• The bracket [ ] indicates it was a tiebreak, not a full set

A regular 7-point set tiebreak would appear as: 7–6 (5) where the number in parentheses is the loser's score in the tiebreak.

The match tiebreak (sometimes called a super tiebreak or championship tiebreak) follows the exact same serving and end-changing rules as a regular tiebreak — the only difference is the target score.

Doubles

In doubles, the team that lost the coin toss (or spin) at the start of the match chooses who serves first in the match tiebreak. The service rotation then follows the same order established for the match, alternating between all four players in 2-point blocks.

The service rotation in a doubles tiebreak must follow the order already established in the match. All four players take turns in the same sequence as the sets — you cannot change who serves a block.

Example: If the set service order was A → C → B → D, the tiebreak follows the same rotation (C serves after A's first point, then B, then D, cycling back to A for the next 2-point block).

Receiving Side

Each team decides before the tiebreak starts which partner will receive from which side. Once decided, partners must maintain those positions for the entire tiebreak. This is the same as for regular games within a set.
