What is single elimination?
In a single elimination tournament, each game is do-or-die. Lose once and your tournament run is over. Winners move through each round until one team remains undefeated and crowned champion.
This format powers the knockout stage of global competitions because it is easy to follow and fast to complete. FIFA World Cup knockout rounds, March Madness elimination games, Wimbledon draws, and many major esports events all use single elimination rules.
