Single elimination is a tournament format where participants compete in matches, and the loser of each match is eliminated from the competition. This continues until only one participant remains, who is declared the winner. Each match is crucial, as there are no second chances for those who lose. In a single elimination tournament, the number of rounds depends on the total number of participants. For example, in a 16-team tournament, there would be four rounds: the first round, semifinals, and the final. This format is commonly used in sports like basketball and tennis, making it straightforward and exciting for both players and fans.
