In tennis, the basic format of scoring includes points, games, and sets. A player must win four points to win a game, unless the score reaches deuce, where a player must win two consecutive points to secure the game. To win a set, a player normally needs to win six games with at least a two-game advantage, but if it reaches a 6-6 tie, a tiebreak may occur to determine the set winner. Matches can be played in best-of-three or best-of-five sets formats, particularly in major tournaments.
