How tennis scoring works — a beginner's guide

Tennis has the most charming scoring system in sport — and the most confusing to newcomers. Why 15, 30, 40? What's deuce? If you've opened a live match and seen 6–4, 3–6, 40–30 and felt lost, this guide explains it in plain English — points, games, sets, deuce and tie-breaks, and how to read a live tennis scoreline on TkaTak Sports. No prior knowledge assumed.

The basics: three levels of scoring

Tennis is played as singles or doubles on a net-divided court. What makes it unusual is that the score is built in three stacked layers: you win points to win a game, you win games to win a set, and you win sets to win the match. Understand those three layers and the whole scoreline makes sense.

Points: 15, 30, 40, game

Within a game, points are counted with tennis's famous sequence:

• 0 points is called "love".
• First point won: 15.
• Second point: 30.
• Third point: 40.
• Fourth point: wins the game — as long as you're at least two points clear.

The server's score is always said first, so 40–30 means the server has three points to the receiver's two.

Deuce and advantage

If both players reach 40 (that's 40–40), it's called deuce. From deuce you must win two points in a row: win the first and you have the advantage ("Ad"); win the next and you take the game. Lose it and it's back to deuce. This is why a single game can swing back and forth many times.

Games and sets

A set is won by the first player to reach 6 games, and you must lead by 2 games (so 6–4 wins, but 6–5 does not — you'd play on to 7–5). If it reaches 6–6, most formats play a tie-break to decide the set.

The tie-break

In a tie-break, scoring switches to plain numbers: first to 7 points, win by two (so it can go 8–6, 10–8, and so on). The set is then recorded as 7–6. Tie-breaks are a fast, tense way to settle an even set without it running on indefinitely.

Winning the match

A match is best of three sets (win two) or, in some elite men's events, best of five (win three). So a completed scoreline like 6–4, 3–6, 7–5 means the winner took the first and third sets, losing the second — two sets to one.

Reading a live scoreline

Put it together and 6–4, 3–6, 40–30 reads as: the first player won set one 6–4, lost set two 3–6, and in the current game of set three leads 40–30. Around it you'll usually see:

• Completed set scores — the games won in each finished set.
• Current game score — the live 15/30/40 (or Ad) count.
• Server indicator — who is serving this game.
