Tennis scoring explained: 15, 30, 40, deuce, and tie-breaks
Understand points, games, sets, advantage, and a typical tie-break.
Tennis has four levels of scoring: points, games, sets, and the match. Within a game, the point sequence is love (zero), 15, 30, and 40.
Deuce and advantage
At 40–40, the score is deuce. Winning the next point gives a player advantage; winning another point wins the game. If the player with advantage loses the next point, the score returns to deuce.
Sets and tie-breaks
A common set format requires six games and a two-game lead. Many events play a tie-break at 6–6; check the event rules. A typical tie-break uses ordinary numbers and is won at seven points with a two-point lead.
