A knockout competition is a type of tournament where participants compete in matches, and the loser is eliminated from the competition. This format continues until only one participant remains, who is declared the winner. Knockout competitions are commonly used in sports, such as football and tennis, as well as in various games and contests. In a knockout format, each round typically consists of a single match or game. The winners advance to the next round, while the losers are out of the tournament. This structure creates a straightforward path to determine the champion, making it exciting for both participants and spectators.
