doubles

In tennis, a game is played with rackets and a ball over a net on a rectangular court. Points are scored when an opponent fails to return the ball within the court's boundaries.

In doubles, two pairs of players compete. The same basic principles of play and scoring apply as in singles. Service alternates between the two opposing teams, and each team decides at the start of a set which partner will serve first. The receiving team also decides at the start of a set which player will receive service first, and they alternate receiving on alternate points within that game and set. A game is won by scoring four points, with a two-point margin required, progressing from 15, 30, 40, to game. Sets are won by winning six games, again with a two-game margin. Tiebreakers are often used to decide sets when the score reaches six games all. Mixed doubles is a form of doubles where each team consists of one man and one woman.123
