Elimination brackets are a type of tournament structure used in competitive events, where participants are eliminated after losing a match. Each match in the bracket determines which competitor advances to the next round, while the loser is removed from the competition. This format continues until only one participant remains, who is declared the winner. Typically, elimination brackets are organized in a single-elimination format, meaning that each competitor has only one chance to win. In some cases, a double-elimination format is used, allowing participants to lose once and still have a chance to compete for the title. This structure is common in sports, gaming, and other competitive activities.
