Scoring

Scoring is identical in the singles and doubles games. A tennis game, when not prolonged by a tie, is played to four points, designated by the terms 15, 30, 40, and game, with zero points being referred to by the term love (possibly derived from the French for “the egg,” l’oeuf, referring to the physical appearance of the number zero). A tie at 40 is called deuce. Because a game must be won by two points, play continues from deuce until one player leads by a margin of two points. After reaching deuce, the player who can win the game on the next point is said to have the “advantage,” while a subsequent tied score is always called deuce. (A system referred to as “no-ad” is sometimes employed in which the winner of the point following the first deuce wins the game.) In tennis competition, the score of the server is always given first. Typical scores at stages of a given tennis game might be “love-15” or “40-30.” The players or teams exchange sides after each odd-numbered game.

Players must win six games to win the set, but they must win by at least two games. Thus, if a set becomes tied at 5-5, at least 7 game victories are required to win the set. A tiebreaker is often employed if a set becomes tied at 6-6. A tiebreaker is generally played to 7 points, but because it too must be won by at least two points, it may be extended. The winner of a tiebreaker is recorded as having won the set 7-6, regardless of the point total achieved in the tiebreaker. Tennis matches are usually the best two out of three sets or the best three out of five sets. At the professional level, women generally play best-of-three sets while men play best of five.
