A standard tennis tie-break is normally played when a tie-break set reaches 6-6. Points are counted as zero, 1, 2, 3 and so on, and the first player or team to reach seven points with a two-point lead wins the tie-break and the set.
The player due to serve starts with one point. The opponent then serves two points, after which the players alternate two-point service turns. Under the standard procedure, players change ends after every six points, and the player who served first in the tie-break receives in the opening game of the next set.
Those are the standard rules. Competitions can announce approved alternatives, including a seven-point or 10-point match tie-break in place of a deciding set, a 10-point tie-break at 6-6 in the deciding set, a short-set tie-break, or a different change-of-ends procedure.
Tie-Break Rules at a Glance
| Format | When It Begins | Winning Target | What It Decides |
|---|---|---|---|
| Standard tie-break | Usually at 6-6 in a tie-break set | 7 points, win by two | The set |
| Short-set tie-break | At the game score announced for a short set | Usually 5 points under the approved short-set option, with a deciding point at 4-4 | The short set |
| Seven-point match tie-break | After the preceding sets are split, if announced | 7 points, win by two | Replaces the deciding set and decides the match |
| 10-point match tie-break | After the preceding sets are split, if announced | 10 points, win by two | Replaces the deciding set and decides the match |
| 10-point final-set tie-break | At 6-6 in the actual deciding set, if announced | 10 points, win by two | The deciding set and match |
Always confirm the competition’s format. “Tie-break” does not automatically mean first to seven, and “10-point tie-break” does not reveal whether it replaces a set or concludes one at 6-6.

When Is a Tie-Break Played?
The standard rules recognize both advantage sets and tie-break sets. The event must announce the chosen method in advance.
In a tie-break set, one side wins by reaching six games with a two-game lead. If the score reaches 6-6, a tie-break decides the set. The final set can use the same procedure or another announced format.
In an advantage set, there is no tie-break at 6-6. Play continues until one side leads by two games, such as 8-6 or 10-8. Players should therefore not start a tie-break merely because the set reaches 6-6 unless the agreed format calls for one.
Some short-set formats begin a tie-break at 4-4 or, at the sanctioning body’s discretion, 3-3. The target and serving procedure can also differ under the approved short-set alternative.
How Many Sets Are in Tennis? Rounds and Draws Explained covers when a match requires two or three winning sets and how that differs from tournament rounds.
How to Score a Standard Tie-Break
A standard tie-break begins at 0-0 and uses ordinary numbers. The first side to reach seven wins only if it leads by at least two points.
Valid winning scores include:
- 7-0 through 7-5
- 8-6
- 9-7
- 10-8
- Any later score with a two-point margin
A score of 7-6 does not end the tie-break because the lead is only one point. Play continues until one side gains a two-point margin.
The winner takes the set 7-6 regardless of the tie-break’s internal score. If the tie-break finishes 10-8, the set score is still 7-6.
Who Serves First in a Tie-Break?
The player whose turn it would be to serve the next game serves the first tie-break point. This is not a new coin toss or choice.
That opening server serves only one point. The opponent serves the next two, and the players then alternate in blocks of two points.
| Tie-Break Point Numbers | Server |
|---|---|
| 1 | Player A |
| 2 and 3 | Player B |
| 4 and 5 | Player A |
| 6 and 7 | Player B |
| 8 and 9 | Player A |
| Continue as needed | Alternate every two points |
A simple memory aid is “one, then two, then two.” Counting total points also shows when a service turn changes. After 1, 3, 5, 7 and every later odd total of completed points, the next server begins a new service turn.
Which Side Does the Server Use?
The first tie-break point is served from the right half of the court, commonly called the deuce side. The service side then alternates after every point.
This produces the following pattern:
| Point About to Be Played | Service Side |
|---|---|
| 1 | Right, or deuce, side |
| 2 | Left, or ad, side |
| 3 | Right, or deuce, side |
| 4 | Left, or ad, side |
| 5 | Right, or deuce, side |
Because the first server has only one point, every later two-point service turn begins from the left and ends from the right. The sides continue to alternate even after an end change.
Serving from the wrong half is corrected as soon as it is discovered. Points already played stand, and a fault served before discovering the wrong side also stands.
When Do Players Change Ends?
Under the standard procedure, players change ends after every six total points. That means after 6, 12, 18, 24 and so on.
Examples:
- At 4-2, six points have been completed, so players change ends.
- At 6-6, 12 points have been completed, so they change again.
- At 9-9, 18 points have been completed, so another change is due.
Play remains continuous during a tie-break change of ends. The standard rules do not provide the ordinary 90-second changeover rest during the tie-break.
The rules also approve an alternative procedure in which players change after the first point and then after every four points. That method applies only when the event adopts it. It should not be mixed with the standard six-point procedure during a match.
Who Serves After a Tie-Break?
The player or team that served the first tie-break point receives in the first game of the next set. Equivalently, the player who received the opening tie-break point serves first in the next set.
This preserves the normal service rotation. It does not depend on who won the tie-break or who served the final point.
Example: Player A was due to serve at 6-6 and therefore served the opening tie-break point. Player B will serve the first game of the following set, even if Player B also served the last point of the tie-break.
Standard Tie-Break vs Match Tie-Break
A standard tie-break decides a set that has reached the announced trigger score, commonly 6-6. A match tie-break replaces the entire deciding set after the players or teams split the preceding sets.
| Detail | Standard Tie-Break | Match Tie-Break |
|---|---|---|
| Starts after | Usually 6-6 in a tie-break set | One set all in best-of-three, or two sets all in best-of-five, when announced |
| Common target | 7 points | 7 or 10 points under approved alternatives |
| Win-by-two rule | Yes | Yes |
| Result | Wins the set 7-6 | Wins the match in place of a deciding set |
| Service pattern | One opening serve, then alternating two-point turns | Same general tie-break pattern |
The original order of service continues into a match tie-break. In doubles, however, each team may change its internal serving and receiving order as it may at the beginning of a new set.
A match tie-break is sometimes called a super tie-break, especially when played to 10. “Match tie-break” is the clearer rules term because it describes the function rather than assuming a particular target.
Match Tie-Break vs Final-Set Tie-Break
These are not interchangeable.
A 10-point match tie-break begins immediately after the players split the preceding sets. No normal games are played in the deciding set because the tie-break replaces it.
A 10-point final-set tie-break begins only after the deciding set reaches 6-6. The players first play the full sequence of games in that final set, then use the longer tie-break to decide the match.
This distinction changes both the duration and the written score. Check whether the competition says “match tie-break in lieu of a final set” or “10-point tie-break at 6-all in the final set.”
Grand Slam Final-Set Tie-Breaks
As of August 2026, all four Grand Slam tournaments use a 10-point tie-break at 6-6 in the deciding set for the principal singles formats. The first player to 10 with a two-point margin wins.
Not every event at a Grand Slam has the same number of full sets. Some doubles, junior or wheelchair formats can use a match tie-break in place of a deciding set. The event regulations and draw format should be checked rather than extending the singles rule to every competition.
How Tie-Breaks Work in Doubles
The scoring target, win-by-two requirement, service-side alternation and standard end changes are the same in singles and doubles. The difference is that four players must maintain the established team orders.
Standard Tie-Break Within a Set
The player whose turn it is in the existing doubles service rotation serves the first point. The player due next for the opposing team serves points two and three. The normal rotation then continues within each team in the same order used during that set.
Receiving positions also continue according to the order established for the set. Partners do not swap their receiving order simply because a tie-break starts.
Match Tie-Break Replacing a Set
A match tie-break functions as a new deciding set for order-setting purposes. Before it starts, a doubles team may alter the order of serving within the team and the order of receiving within the team. Once play begins, the chosen order controls.
For the full regular-game service and receiving rotations, see Tennis Doubles Rules Explained.
How a Tie-Break Appears in a Match Score
The set itself is recorded 7-6. A parenthetical number may show the losing side’s tie-break points.
| Written Set Score | Meaning |
|---|---|
| 7-6(3) | The tie-break finished 7-3 |
| 7-6(5) | The tie-break finished 7-5 |
| 7-6(8) | The tie-break finished 10-8 |
Different scoreboards and publications may display the internal score differently, but the set winner still receives one set, not extra games for each tie-break point.
A match tie-break that replaces the deciding set may be shown in brackets, parentheses or as a separate tie-break score depending on the organizer’s scoring system. The competition’s official result is the controlling record.
What Happens if the Wrong Player Serves?
All completed points stand when a rules error is discovered. The correction depends on when a player served out of turn in the tie-break:
- If the error is discovered after an even number of points has been played, correct the service order immediately.
- If it is discovered after an odd number of points has been played, the altered service order remains.
Fault treatment also depends on whether the error involves opponents or doubles partners. In an officiated match, players should ask the chair umpire or referee to apply the rule rather than trying to reconstruct it from memory.
If players are merely on the wrong end, they move to the correct ends as soon as the error is discovered and continue according to the score. Previously played points stand.
Common Tie-Break Mistakes
Giving the Opening Server Two Points
The opening server serves only point one. The opponent serves points two and three.
Starting From the Left Side
The first point starts on the right, or deuce, side. Service sides then alternate every point.
Ending at 7-6
The tie-break must be won by two. A one-point lead is never sufficient in a standard seven-point or 10-point win-by-two format.
Changing Ends at Six on the Scoreboard Instead of Six Total Points
Add both players’ points. A score of 5-1 is six total points and triggers the standard end change; 6-1 is seven total points and does not.
Letting the Tie-Break Winner Serve First in the Next Set
The winner is irrelevant to the next-set service order. The opening tie-break server receives in the first game of the following set.
Assuming Every 10-Point Tie-Break Replaces a Set
A 10-point match tie-break replaces a deciding set. A 10-point final-set tie-break occurs at 6-6 inside that set.
Changing Doubles Order Mid-Tie-Break
In a standard tie-break within a set, teams retain their set order. A team may reset its internal order only before a match tie-break that replaces the deciding set.

A Point-by-Point Serving Example
Suppose Player A was due to serve at 6-6:
| Point | Server | Side | Score After Point, Example Only |
|---|---|---|---|
| 1 | A | Right | A leads 1-0 |
| 2 | B | Left | 1-1 |
| 3 | B | Right | B leads 2-1 |
| 4 | A | Left | 2-2 |
| 5 | A | Right | A leads 3-2 |
| 6 | B | Left | 3-3, then change ends |
| 7 | B | Right | B leads 4-3 |
| 8 | A | Left | 4-4 |
| 9 | A | Right | A leads 5-4 |
| 10 | B | Left | 5-5 |
| 11 | B | Right | B leads 6-5 |
| 12 | A | Left | 6-6, then change ends |
Player A serves point 13 from the right side. Play continues until one player leads by two. Regardless of the result, Player B serves the first game of the next set because Player A served the opening tie-break point.
Final Takeaway
For a standard tie-break, remember four rules: first to seven and win by two; the opening server serves once; service then alternates every two points; and players change ends after every six points under the standard procedure.
Then confirm the event variation. A match tie-break may be first to seven or 10 and replace a deciding set, while a 10-point final-set tie-break starts at 6-6 within the deciding set.

Frequently Asked Questions
Is a tennis tie-break first to seven or first to 10?
A standard tie-break is first to seven with a two-point margin. Approved match and final-set formats can be first to 10, while a seven-point match tie-break is also permitted. The announced competition format controls.
Who serves the second point of a tie-break?
The opponent of the opening server serves the second point and also the third point. After that, service alternates in two-point turns.
Do players get two serves in a tie-break?
Yes. The normal first-service and second-service rules apply to each tie-break point unless an approved event variation changes service lets, not the number of service attempts.
Do players rest when changing ends in a tie-break?
Under the standard rules, play is continuous during tie-break end changes. Players change sides without the normal changeover rest.
What is a mini-break?
A mini-break is an informal term for winning a point served by the opponent during a tie-break. It has no separate value in the rules; it still counts as one tie-break point.
Can a tie-break finish 20-18?
Yes. A win-by-two tie-break continues without a fixed maximum until one side gains a two-point lead.
Does the same player always serve first in every tie-break?
No. The player whose turn it is in the match service order serves the opening point. The order continues through sets and is not chosen according to tie-break preference.
