How Tennis Scoring Works (Deuce, Advantage, Tiebreaks Explained)
Game points climb 0 (love), 15, 30, 40, and the game is won by whoever reaches the 4th point while leading by at least 2 points. If both players reach 40, it's "deuce" β the next point won earns "advantage." If the player with advantage wins the following point too, they take the game; if their opponent wins it instead, the score returns to deuce and the cycle can repeat indefinitely. A set is won by taking 6 games with at least a 2-game lead; if the set reaches 6 games apiece, a tiebreak (first to 7 points, win by 2) decides the set instead.
