From Love-All to Game, Set, Match
The win-by-two rule connects deuce, extended sets and tiebreaks, while format checks clarify no-ad play, 6-6 and deciding-set match tiebreaks.
Tennis scoring sounds complicated because the sport uses several scoring systems at once. Within a game, the score moves from love to 15, 30, and 40. Sets count games with ordinary numbers. Tiebreaks count individual points numerically, and matches count sets.
The simplest way to understand the system is as four nested layers:
Points win a game. Games win a set. Sets win a match.
Most of the apparent complications are applications of one principle: win by two. It explains why a game can return to deuce repeatedly, why some sets continue beyond six games each, and why a tiebreak may exceed its nominal target.
The fundamentals are stable, but match formats vary. Before playing, confirm whether games use advantage or no-ad scoring, what happens when a set reaches 6-6, and whether a 10-point match tiebreak replaces the deciding set.
Format note: This guide explains common scoring structures. The rules stated by the tournament, league, organizer, or official control the particular match.
The four layers of a tennis score
A tennis match consists of small contests nested inside larger ones. Players win points to complete a game, games to complete a set, and the required number of sets to complete the match. In standard advantage scoring, a game requires at least four points and a two-point lead; a conventional set requires at least six games and a two-game lead, subject to its tiebreak format. Best-of-three means first to two sets, while best-of-five means first to three sets. The LTA’s rules and scoring guide summarizes this hierarchy and its basic thresholds.
| Layer | What you are trying to win | Basic requirement |
|---|---|---|
| Point | One rally or serve sequence | Win the rally or receive the point when the opponent loses it |
| Game | A group of points | In a standard advantage game, win at least four points and lead by two |
| Set | A group of games | Conventionally, win at least six games and lead by two, subject to the applicable tiebreak procedure |
| Match | A group of sets | Win two sets in best-of-three or three sets in best-of-five |
The unusual terminology belongs mainly to the point layer. A game begins at love-all and progresses through 15, 30, and 40. When the game ends, those point totals disappear, the winner adds one game to the set score, and the next game begins at love-all.
Four points are enough to win a standard game only when they create the required two-point margin. A player who is up 40-love, 40-15, or 40-30 wins the game by winning one more point Tennis Scoring: Points, Sets & Games | Tennis Rules | USTA. At three points each—40-40—the score is deuce.
A conventional set follows a similar pattern. Six games can complete the set at 6-0, 6-1, 6-2, 6-3, or 6-4 because the winner leads by at least two games. A 6-5 score is not complete. At 6-6, the stated format determines whether the players contest a tiebreak or continue playing regular games.
At match level:
- Best-of-three means the first player or team to win two sets wins the match.
- Best-of-five means the first player or team to win three sets wins the match.
“Best of” describes the maximum scheduled number of sets, not the number that must always be played. A best-of-three match can finish in two straight sets. A best-of-five match can finish in three, four, or five sets.
The win-by-two principle connects the layers. It applies to standard advantage games, conventional sets until a tiebreak procedure intervenes, and tiebreaks themselves. Reaching a nominal target is not enough when the lead is only one.
No-ad games, advantage sets, match tiebreaks, and competition-specific deciding-set procedures are variations rather than universal rules. Learn the standard structure first, then confirm the format for the match you are about to play or watch.
How points are counted and announced
Within a standard game, tennis uses traditional terms for the first four point totals. The server’s score is normally announced before the receiver’s score, and “all” indicates an equal score below deuce. These conventions are set out in Tennis Canada’s beginner scoring overview.
| Points won in the game | Tennis score |
|---|---|
| 0 | Love |
| 1 | 15 |
| 2 | 30 |
| 3 | 40 |
| 4 or more | Game, if the player leads by two |
If the server has won two points and the receiver has won one, the score is 30-15. If those totals are reversed, it is 15-30.
When the players are level, the score is commonly called as follows:
- 0-0: love-all
- One point each: 15-all
- Two points each: 30-all
- Three points each: deuce, rather than 40-all
Consider a game in which the server wins most of the points:
- The game begins at love-all.
- The server wins: 15-love.
- The server wins again: 30-love.
- The receiver wins: 30-15.
- The server wins: 40-15.
- The server wins again: game.
The last point completes the game because the server has won at least four points and leads by at least two. The point score resets to love-all for the next game, while the set score increases by one game for the winner.
It is tempting to memorize the rule as “four points win a game,” but that is incomplete. Winning a fourth point does not end the game if both players have already won three points. The eventual winner may need five, six, ten, or more total points before establishing a two-point lead.
Here is a second example beginning at 30-30:
- Player A wins the next point: 40-30.
- Player A wins again: game.
Player A wins because two consecutive points from an even score create a two-point margin.
If Player B had won the point at 40-30, the score would have become deuce. It would not be announced as 40-all or reset to 30-30. From that stage onward, “deuce” identifies the tied position whenever neither player holds the advantage.
A brief historical note: The precise origins of 15, 30, 40, and the word “love” are uncertain. The familiar clock-face explanation is one theory, not an established account. Those historical debates do not affect how modern tennis is scored.
Deuce and advantage, point by point
When both players have won three points in a standard advantage game, the score is 40-40, called deuce. From deuce, a player must win two consecutive points: the first creates advantage, and the second wins the game. Losing the point while holding advantage returns the score to deuce, as the USTA scoring guide explains.
The name of the advantage depends on who holds it:
- Ad-In means advantage to the server.
- Ad-Out means advantage to the receiver.
Here is the return-to-deuce loop:
- Deuce
- Server wins the point: Ad-In
- Receiver wins the next point: Deuce
The receiver does not move directly from behind to Ad-Out. The score first returns to an even position.
Now consider a game-winning sequence for the receiver:
- Deuce
- Receiver wins the point: Ad-Out
- Receiver wins again: game to the receiver
Because the receiver has won the opponent’s service game, the result is also called a break of serve.
A break point is any point on which the receiver can win the current game. Ad-Out is a break point. So is 30-40, because the receiver will take the game by winning the next point. At love-40, the receiver has three consecutive opportunities to break, although each opportunity is a separate break point.
There is no fixed maximum length for a standard advantage game. The score can cycle from deuce to advantage and back to deuce as many times as necessary.
A compact way to remember the sequence is:
At deuce, two in a row wins. Split the next two points, and the score returns to deuce.
Some matches use no-ad scoring instead. In that format, the point immediately after deuce decides the game. There is no Ad-In, Ad-Out, or repeated deuce loop. Because this changes how a game ends, players should establish the format before starting.
Winning a set: what happens at 5-5, 6-5, and 6-6
In a conventional set, a player or team must reach at least six games and lead by two, unless the applicable tiebreak procedure settles the set. A tiebreak set commonly introduces a tiebreak at 6-6; an advantage set instead continues until one side leads by two games. The distinction is summarized in the LTA’s scoring guidance.
The simplest completed set is 6-4. The winner has reached six games and leads by two. A score of 6-5 is not complete because the lead is only one game.
Near the end of a set:
- At 5-5: Neither player can win the set with only one more game. Taking the next two games produces a 7-5 set.
- At 6-5: The leader wins the set by taking the next game, again producing 7-5.
- At 6-5: If the trailing player wins the next game, the score becomes 6-6.
- At 6-6: The next step depends on the stated set format.
In a tiebreak set, the players contest a tiebreak at the specified trigger score—commonly 6-6. The tiebreak winner takes the set, which is recorded as 7-6.
In an advantage set, no tiebreak is played at 6-6. Regular games continue until one side leads by two. Completed scores could include 8-6, 9-7, or 12-10. Intermediate scores such as 7-6, 8-7, or 12-11 remain unfinished because the margin is only one game.
Here is a more complete decision tree:
Has either side reached at least six games?
│
├─ No → Continue the set.
│
└─ Yes
│
├─ Does one side lead by two games?
│ └─ Yes → The set is over.
│
└─ No
│
├─ Has the specified tiebreak trigger been reached?
│ └─ Yes → Play the stated tiebreak.
│
└─ No, or this is an advantage set
→ Continue regular games until one side leads by two
or the competition's later tiebreak trigger is reached.
Do not assume every set automatically uses a tiebreak at 6-6. The procedure may vary by event, league, age group, or recreational agreement. A scoreboard showing 6-6 does not, by itself, tell you what comes next.
That is also why “first to six games” is only shorthand. Six games win a conventional set only when accompanied by the necessary margin. At 6-5, the set continues; at 6-6, the governing format takes over.
How a standard seven-point tiebreak works
A standard set tiebreak uses ordinary numbers—0, 1, 2, 3, and so on—rather than love, 15, 30, and 40. It is won by reaching at least seven points with a two-point lead. The opening server serves one point from the deuce court; the opponent then serves two points beginning from the ad court, and service continues in two-point turns. Players change ends after every six tiebreak points, according to Tennis Canada’s tiebreak explanation.
The winning requirement means:
- 7-5 is complete.
- 7-6 is not complete.
- 8-6 is complete.
- 12-10 is complete.
There is no fixed maximum. At 7-6, the leader must win the next point to finish 8-6. If the trailing player instead wins, the score becomes 7-7 and play continues.
Call the player due to serve next Player A. The service rotation begins:
- Player A serves point 1.
- Player B serves points 2 and 3.
- Player A serves points 4 and 5.
- Player B serves points 6 and 7.
- The players continue taking two-point service turns until the tiebreak ends.
The service side alternates every point. Player A opens from the deuce court. Player B begins the first two-point turn from the ad court, then serves the next point from the deuce court. Each subsequent two-point turn also begins from the ad court and finishes from the deuce court.
| Tiebreak point | Server | Service side | Change ends afterward? |
|---|---|---|---|
| 1 | Player A | Deuce court | No |
| 2 | Player B | Ad court | No |
| 3 | Player B | Deuce court | No |
| 4 | Player A | Ad court | No |
| 5 | Player A | Deuce court | No |
| 6 | Player B | Ad court | Yes |
| 7 | Player B | Deuce court | No |
| 8 | Player A | Ad court | No |
| 9 | Player A | Deuce court | No |
| 10 | Player B | Ad court | No |
| 11 | Player B | Deuce court | No |
| 12 | Player A | Ad court | Yes |
The same pattern continues after point 12, with another end change after point 18 if the tiebreak lasts that long.
If Player A wins the tiebreak 7-5, Player A wins the set 7-6. The tiebreak points determine the set winner but do not become additional games. The set is not recorded as 13-11.
The post-tiebreak service rule often causes confusion. The player or team that served the opening point of the tiebreak receives in the first game of the following set. A tiebreak is treated as the service game of its opening server for purposes of service alternation, as explained in the USTA’s scoring guidance.
From sets to the match: best-of-three and best-of-five
A best-of-three match is won by the first player or team to take two sets. A best-of-five match is won by the first to take three. ATP and WTA Tour matches are generally best-of-three, while men’s Grand Slam singles is a prominent best-of-five format and women’s Grand Slam singles uses best-of-three, according to the ATP Tour’s introductory format guide. These professional examples should not be applied automatically to local, junior, collegiate, or recreational competition.
A straight-sets best-of-three result might be:
6-4, 6-3
The winner took the first two sets, so a third was unnecessary. A best-of-three match can therefore last two or three sets.
If the score is:
6-4, 3-6
each player has won one set. The match now requires a deciding segment, but its form depends on the competition rules.
A four-set best-of-five result might be:
6-3, 4-6, 6-2, 7-5
The winner took the first, third, and fourth sets. A fifth set was unnecessary because that player had already reached three set wins.
Even after confirming how many sets are needed, you must know the deciding-set procedure. A match tied at one set each might proceed to:
- a full advantage set;
- a regular tiebreak set; or
- a 10-point match tiebreak replacing the deciding set.
The same principle applies to a best-of-five match that reaches two sets all: the competition’s rules determine how the final set is resolved.
The central distinction is simple: sets determine the match, but the procedure for playing the deciding set can vary.
No-ad scoring, match tiebreaks, and doubles variations
The standard advantage format is only one way to organize a match. Shortened formats are common in doubles, leagues, and time-limited events, but they should never be assumed without checking the rules.
No-ad scoring changes what happens at deuce:
- The score reaches deuce.
- One deciding point is played.
- The winner of that point wins the game.
Under common doubles no-ad procedures, the receiving team may be given a choice affecting the return side or receiver for the deciding point. The precise choice is competition-specific, so players must follow the organizer’s stated procedure rather than treating one version as universal. A commercial beginner’s guide from On describes one common doubles no-ad format.
A 10-point match tiebreak, sometimes called a match breaker or super tiebreak, is won by reaching at least 10 points with a two-point lead. It may replace a full deciding set and therefore decide the match directly. It generally uses the same service rotation as a standard tiebreak: one opening service point followed by alternating two-point turns. UTR Sports’ tiebreak guide describes the seven-point and 10-point versions.
| Feature | Standard set tiebreak | 10-point match tiebreak |
|---|---|---|
| Usual purpose | Completes a set tied at its specified trigger score | Replaces a full deciding set |
| Point target | At least 7 | At least 10 |
| Winning margin | 2 points | 2 points |
| Possible completed scores | 7-5, 8-6, 12-10 | 10-8, 11-9, 15-13 |
| Result notation | Set is usually recorded as 7-6 | Notation varies by organizer |
For example:
6-4, 3-6, 10-8
can indicate that the winner took the first set, lost the second, and then won a 10-point match tiebreak instead of playing a full third set.
Singles and doubles share the same basic hierarchy of points, games, sets, and matches. Doubles formats, however, often introduce no-ad games or a match tiebreak in place of a complete deciding set. That does not mean every doubles match uses those alternatives.
Before starting any organized or casual match, answer four questions:
- How many sets are scheduled?
- Are games played with advantage or no-ad scoring?
- What happens at 6-6 in each set?
- Does a 10-point match tiebreak replace the deciding set?
If a tournament sheet, league rule, organizer, or official specifies a format that differs from a general beginner guide, follow the competition’s stated format.
How to read, call, and keep a tennis score
A written match score lists completed sets in the order they were played. Published results are often presented from the winner’s perspective, but scoreboards and organizer records may use a different display convention.
Consider:
6-4, 3-6, 7-6(5)
This means:
- The eventual winner took the first set 6-4.
- The opponent took the second set 6-3.
- The eventual winner took the third set 7-6.
- The parenthetical (5) indicates that the losing side scored five points in the final-set tiebreak, making the tiebreak score 7-5. This notation is explained in a detailed scoreline guide from KeepTheScore.
Now consider:
6-4, 3-6, 10-8
This may represent a match in which a 10-point match tiebreak replaced the third set. Notation practices differ: an organizer may place the match-tiebreak score in brackets, separate it typographically, or record the deciding segment according to its scorecard system. The competition format and scoreboard labels provide the necessary context.
A full scoreboard may show several layers simultaneously:
- player or team names;
- completed-set scores;
- games in the current set;
- points in the current game;
- an indicator identifying the current server.
For example:
| Player | Set 1 | Set 2 | Current set | Current game |
|---|---|---|---|---|
| Player A | 6 | 3 | 4 | 30 |
| Player B | 4 | 6 | 2 | 15 |
Player A won the first set, Player B won the second, and Player A leads 4-2 in the deciding set. The current point score is 30-15. You still need the service indicator to know who is serving and how the point score should be spoken.
Calling the score on court
Before each serve, the server should announce the point score clearly, giving the server’s score first. At the beginning of a new game, stating the set’s current game score can also prevent confusion.
For example:
“Games are 3-2. Love-all.”
After the first point, the server might call:
“15-love.”
If the receiver wins the next two points, the calls become:
“15-all,” then “15-30.”
Clear, regular announcements allow players to correct a disagreement immediately instead of reconstructing several previous points.
Players ordinarily change ends after the first game and thereafter whenever the total number of completed games is odd—after totals of 1, 3, 5, 7, and so on. During a tiebreak, they instead change ends after every six points.
Concise scoring glossary
- Ace: A valid serve that wins the point without being touched by the receiver.
- Fault: An unsuccessful service attempt, such as a serve that misses the proper service box.
- Double fault: Two consecutive faults on the same point; the server loses the point.
- Let: In the familiar service situation, a serve that touches the net and lands in the correct service box; the serve is replayed.
- Break point: A point on which the receiver can win the server’s game.
- Set point: A point on which a player or team can win the set.
- Match point: A point on which a player or team can win the match.
An ace adds one point. A double fault awards the point to the receiver, while a valid let serve is replayed without adding a point. The ATP Tour’s tennis terminology primer defines aces, faults, double faults, and break points in their scoring context.
Quick self-test

The score is 30-15 and the server wins the next point. What is the score? Answer: 40-15.
-
Is a tiebreak over at 7-6? Answer: No. The lead is only one point. The score must become 8-6 or return to 7-7.
-
Player A serves the opening point of a tiebreak. Who serves points 4 and 5? Answer: Player A. Player B serves points 2 and 3 before Player A takes the next two-point turn.
Tennis scoring FAQs
Why does tennis use love, 15, 30, and 40?
The exact historical origins are uncertain. One familiar theory connects 15, 30, and 40 to a clock face, with an earlier 45 eventually becoming 40, but that explanation is disputed rather than definitive. Proposed origins for “love” are similarly uncertain.
For modern scoring, the useful sequence is simply love, 15, 30, 40, game, subject to the two-point winning requirement.
Can a tennis game or tiebreak continue indefinitely?
A standard advantage game and a win-by-two tiebreak have no fixed maximum score.
A game can return from advantage to deuce repeatedly until one player wins two consecutive points. A tiebreak can continue beyond 7-7, 10-10, or any later tie until one side leads by two.
“No fixed maximum” means the rules impose no final numerical ceiling—not that a contest must literally continue forever.
Who serves first in a match and in a tiebreak?
Before the match, the initial choice may be settled through a racquet spin or another procedure prescribed by the competition. The winner generally receives a choice involving serve, receive, court end, or deferral; a coin toss should not be treated as the only possible method.
In a tiebreak, the player or team due to serve the next game serves the opening point. The opponent serves points 2 and 3, after which service continues in two-point turns. The opening tiebreak server receives in the first game of the following set.
What is the difference between a tiebreak and a match tiebreak?
A standard set tiebreak normally decides a set. Its target is at least seven points with a two-point margin, and its winner takes the set 7-6.
A match tiebreak commonly has a target of at least 10 points, also with a two-point margin. It may replace a full deciding set, so winning it can end the match directly. The distinction concerns its purpose and target rather than an entirely different service system.
Is tennis scoring the same in singles and doubles?
The basic structure is the same: points win games, games win sets, and sets win matches. Love, 15, 30, 40, deuce, advantage, and numerical tiebreak scoring can appear in both singles and doubles.
The format may differ. Doubles competitions often use no-ad games or replace a full deciding set with a 10-point match tiebreak, but these variations are not universal. Doubles also requires an established service and receiving order among the four players.
Always use the organizer’s rules rather than assuming that a professional or previously encountered doubles format applies everywhere.
Tennis scoring ultimately returns to four layers: call the points correctly, use those points to complete games, track the games through the set, and count the sets required for the match. Deuce and tiebreaks are not unrelated complications; both apply the same win-by-two principle when a contest becomes close.
Before playing, confirm three practical details: whether games use advantage or no-ad scoring, what happens at 6-6, and whether a 10-point match tiebreak replaces the deciding set.
