A set of tennis is typically composed of a number of games, making it an integral part of the match structure. The standard format for most professional and amateur matches involves winning six games to secure a set, provided the player has at least a two-game lead over the opponent. If both players reach six games each, a tiebreaker may be played to determine the winner of the set. This format ensures a competitive and fair determination of the winner in each set, contributing to the overall excitement and dynamic of the game.
