Deuce and advantage: reading the score inside a tennis game

A tennis scoreboard contains several layers, and the smallest one can be the most confusing. Inside a standard advantage-scoring game, points progress through love, fifteen, thirty and forty. The United States Tennis Association’s scoring guide explains that love means zero and that forty-all has a separate name: deuce.

The sequence is a scoring convention, not a series of distances or time intervals. A player normally needs at least four points to win a game, but reaching that number does not always finish it. Once both players have won three points, the game requires a two-point sequence from deuce rather than ending with the very next point.

The first point after deuce creates an advantage. If the server wins it, the call is advantage in; if the receiver wins it, advantage out. The side holding the advantage wins the game by taking the following point. If that side loses the point, the score returns to deuce and the same process begins again.

This is why a long game can contain repeated game-point opportunities without adding another game to the set score. Distinguish the point score from the number of games already won. A broadcast may show both at once, and an apparent change in one part of the display does not necessarily mean the set has moved closer to completion.

When joining a match midstream, first identify who is serving, then read the current game score, the set’s game totals and finally the sets won. This explanation concerns standard advantage scoring; competition formats can use alternatives. Establishing the format before interpreting a dramatic point is more reliable than assuming every tennis match uses exactly the same route to a game.
