A player or team must win a minimum of six games to win a set but must also have a lead of at least two games over their opponent. Matches are typically played in best-of-three or best-of-five sets. Winning a set is crucial for match success, and players employ various strategies and techniques to secure the necessary games. The competitive structure of sets helps to provide thrilling and strategic gameplay throughout a match.
