Single elimination is a tournament format where participants compete in matches, and the loser of each match is eliminated from the tournament. This continues until only one participant remains, who is declared the winner. Each match is crucial, as losing means the end of the competition for that participant. In a single elimination tournament, the number of rounds depends on the total number of participants. For example, in a tournament with 8 teams, there would be three rounds: quarterfinals, 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.
