A single-elimination bracket 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 round halves the number of competitors, making it a straightforward way to determine a champion. In a single-elimination setup, each match is crucial, as losing means the end of the tournament for that participant. This format is commonly used in various competitions, including sports tournaments, video game competitions, and reality TV shows, due to its simplicity and excitement.
