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 structure is often organized in brackets, with each round reducing the number of competitors. This format is commonly used in sports events, such as basketball and tennis, as well as in competitions like reality TV shows and video game tournaments.
