how many points must be won by one player to complete a game of women’s singles?

In women's singles tennis, to complete a single game, a player must win at least four points and be ahead by a margin of two points. The scoring within a game goes from Love (0 points), 15 (1 point), 30 (2 points), 40 (3 points), and then Game (4 points or more). If both players reach 40-40, this is called "deuce," and the player must then win two consecutive points-first gaining the "advantage" and then the game-to complete the game
