An elimination tournament is a competitive format where participants compete in matches, and the loser of each match is eliminated from the tournament. This process continues until only one participant remains, who is declared the winner. Elimination tournaments are commonly used in sports, such as basketball and tennis, as well as in various games and contests. In an elimination tournament, the structure can vary, with formats like single-elimination or double-elimination. In a single-elimination format, a participant is out after one loss, while in a double-elimination format, participants have to lose twice before being eliminated. This structure creates a straightforward path to determine the champion.
