A single-elimination tournament (also known as a knockout tournament or the sudden-death tournament) is a type of elimination tournament where the loser of each match (or round or game) is eliminated from the tournament. Conversely, the winners move to the next rounds until only one winner is left.
The round indicates how far the competitor has advanced in a single elimination bracket. Rounds are referred to by their power of two. During larger draws, the round of 64, or 64's, is referred to as the round with 64 players remaining. A round of 32, or 32's, is the next round with 32 participants remaining in the bracket. Round of 16, also known as the sweet 16, is the round in which 16 people remain. It is most commonly known as the Quarterfinals, or the Quarters, when only eight teams remain. As a result of that round, the winners advance to the semis, where only four competitors remain. Often called the finals or championship match, the final round pits the two winners against each other.
A 3rd place playoff is often held in single elimination brackets, where the two semi-final losers compete for 3rd place. The loser of both semi-final matches may receive 3rd place in tournaments with a limited amount of time.
