Tiebreakers are used in tennis to decide closely contested sets, providing a structured way to determine a winner when the score reaches 6-6. They add an extra layer of strategy and pressure, with every point becoming increasingly important as players compete to gain the advantage.
Understanding how tiebreakers work can make it easier to follow the flow of a match, whether you’re watching a Grand Slam final or playing recreational tennis. While the basic principles are straightforward, the exact format can vary depending on the competition and whether the match is singles or doubles.
This blog post explains when tiebreakers are used, how they are scored, the different types of tiebreakers you may encounter, what happens after a tiebreaker is played, and addresses some common misconceptions about the rules.

What Is a Tennis Tiebreaker?
A tennis tiebreaker is a special game used to decide a set when both players or teams have won six games each. It prevents the set running on indefinitely and provides a straightforward way to settle things fairly. Once the tiebreak is complete, the set is closed and the match continues with the next set if required.
Rather than continuing regular games, the tiebreaker offers a clear route to a result. Unlike standard game scoring, points are counted 0, 1, 2 and so on. Players compete to a set number of points, usually seven, and must lead by at least two to win. That means a tiebreak can finish 7-5, 8-6, 10-8 and so on. On scoreboards the set is typically shown as 7-6 to the winner, with the tiebreak score in brackets, for example 7-6 (7-4).
During a tiebreaker, the player due to serve next starts with a single point from the right-hand (deuce) court. The opponent then serves two points, and from there they alternate in twos. Players change ends every six points to keep conditions even. When the tiebreak ends, the player who received first will serve to start the next set.
Formats can vary by event. Most singles sets use a first-to-seven tiebreak, while many competitions now play a first-to-ten tiebreak in a deciding set, and doubles often use a match tiebreak to ten instead of a full third set. Always check the specific tournament rules for the format in play.
When Are Tiebreakers Used in Tennis?
Tiebreakers are played when a set reaches 6-6. They prevent sets from running indefinitely and help tournaments stay on schedule, which matters when there are several matches in a day. While some events once used advantage sets, most professional competitions now rely on a tiebreak.
Many events use the standard seven-point tiebreaker for any set that reaches 6-6. The first player to seven points wins, provided there is a two-point margin. Some formats vary, and since 2022 the Grand Slams use a first-to-10 tiebreak at 6-6 in the final set.
In doubles, a match tiebreak to 10 points often replaces a full third set at tour level.
A tiebreaker is not used if a player has already earned a two-game lead before 6-6, for example 6-4. It only starts once the set score is level at six games each.
Tennis Tiebreaker Scoring Explained
Tiebreakers use straightforward point counting. Instead of 15, 30 and 40, each point is counted as 1, 2, 3 and so on. A point won by the returner is often called a mini-break, as it puts extra pressure on the server.
Most sets use a tiebreak at 6-6 in games, although formats can vary by event. On scoreboards, the completed set is usually shown with the tiebreak score in brackets, for example 7-6 (7-4).
Serving follows a set pattern:
- The player due to serve next in the set serves the first point of the tiebreaker from the right-hand (deuce) court.
- The serve then switches to the opponent for two points, played from the left-hand (ad) court then the right-hand court.
- From there, players alternate serving two points at a time.
This means only the very first server delivers one point in a row, and each server after that delivers two. The order of serve for the rest of the match continues from where the set left off.
Players change ends every six points, for example at 3-3, 6-6 and so on. This helps balance conditions such as sun, wind or shadows, and applies no matter who is serving next.
The first to reach seven points with a margin of two wins the tiebreaker. If the score reaches 6-6, play continues until one player leads by two points, so scores like 8-6 or 10-8 are possible. The player who served the first point of the tiebreak receives in the first game of the next set. Some competitions use a 10-point deciding tiebreak, especially in doubles or as a final-set decider, still won by two.
How Do You Win a Tiebreaker in Tennis?
To win a standard tiebreaker, a player or team must reach at least seven points and be ahead by two. If the scores are level at 6-6, play carries on until that two-point gap appears. Scores like 8-6 or 10-8 are common, and occasionally it stretches further when neither side yields ground.
Taking the tiebreaker ends the set immediately and can shift the momentum of the match. Some events use a first-to-10 tiebreak in a deciding set or in doubles, still needing a two-point margin.
Different Types of Tiebreakers
Tennis uses more than one type of tiebreaker, depending on the competition rules. Each format has a clear purpose and slightly different length.
Classic Tiebreaker
The classic tiebreaker is usually played to seven points with a two-point margin. It is the standard option when a set reaches 6-6 and provides a quick, fair finish to the set.
The next server starts with one point, then service alternates every two points. Players change ends after every six points.
Match Tiebreaker
A match tiebreaker, also called a super tiebreaker, is commonly used in doubles and shortened formats. It is played to 10 points with a two-point margin and replaces a full deciding set, which helps bring matches to a timely conclusion. Teams can choose their serving order, and ends switch every six points, just as in the classic version.
Tiebreaker Rules for Singles and Doubles
Tiebreakers feature in both singles and doubles, with small differences in how serving rotates. A standard tiebreak is played to at least seven points, win by two. Some events, especially in doubles, use a match tiebreak to ten, but the rotation below is the same.
In singles, players switch ends every six points and follow the serving pattern described above. The player due to serve next in the set serves the opening single point from the right-hand (deuce) court. Thereafter service alternates in twos, starting on the left-hand (advantage) court. Ends change at 6, 12 and so on, and the player who received the first point of the tiebreak serves first in the next set.
In doubles, teams keep their established serving order from the set. The player whose turn it is to serve next for that team serves when it is their side’s turn in the tiebreaker. After the opening single point, each server delivers two points in sequence: opponents for points two and three, the first server’s partner for points four and five, then the remaining opponent, and so on. Partners also keep their receiving order, and teams change ends every six points to keep court conditions even.
What Happens After a Tiebreaker?
When the tiebreaker ends, the winner is awarded the set by a score of 7-6, with the tiebreak points sometimes shown in brackets, for example 7-6(4). For formats that use a longer decider, some outlets show the full tiebreak score in the brackets, such as 7-6(10-8).
Players change ends, then start the next set if the match continues. The player who served first in the tiebreaker receives in the first game of the next set, so the other player serves to begin it. In doubles, the team that did not serve first in the tiebreak serves first in the next set, and can choose which partner takes that opening service game.
If the tiebreaker decided the final set, the match ends there and the tiebreak result determines the winner. Rules can vary across events, with some using a 10-point tiebreak in the decider or, in certain doubles, a match tiebreak shown in brackets like [10-7].
Common Myths About Tiebreakers
There are a few misunderstandings about how tiebreakers work. Here are some of the most frequent, along with the facts. Knowing the basics helps matches run smoothly, and competition rules will always set out the exact format for your event.
Myth: You only need to win by one point in a tiebreaker.
Fact: You must win by at least two points, even if the score goes beyond seven.
For example, 7-5 or 8-6 would end a standard seven-point tiebreak, while 7-6 would continue until one side leads by two.
Myth: Tiebreakers are only for singles.
Fact: They are used in both singles and doubles, with only minor adjustments to serving order.
In doubles, partners keep the same serving and receiving order they used in the set, and players change ends after every six points.
Myth: The same player always serves first in every tiebreaker.
Fact: The next server in the normal rotation starts the tiebreaker, then serves alternate as one point, then two points each.
After the opening point, service continues in blocks of two, and the player or team that received first in the tiebreak serves to start the next set.
Myth: All tournaments use identical tiebreak rules.
Fact: Most use the seven-point format at 6-6, but some events use a 10-point tiebreaker in a deciding set.
Grand Slam events now use a first-to-10 final-set tiebreak at 6-6, and many leagues or club matches may use a match tiebreak instead of playing a full third set.
