Tournaments

A single-elimination, knockout, or sudden death tournament is a type of elimination tournament where the loser of each match-up is immediately eliminated from the tournament. Each winner will play another in the next round, until the final match-up, whose winner becomes the tournament champion. Defeated competitors play no further part after losing except for losing semi-finalists where an optional third place playoff can happen.

In this single elimination tournament type, defeated competitors get to participate in "consolation" or "classification" matches against other losers to determine the lower final rankings.

A double-elimination tournament is a type of elimination tournament competition in which a participant ceases to be eligible to win the tournament upon having lost two games or matches. It stands in contrast to a single elimination tournament, in which only one defeat results in elimination.
Competitors are broken into two sets of brackets, the winners' bracket and losers' bracket (W and L brackets for short; also referred as championship bracket and elimination bracket, upper bracket and lower bracket, or main bracket and repechage) after the first round. The first-round winners proceed into the W bracket and the losers proceed into the L bracket. The W bracket is conducted in the same manner as a single-elimination tournament, except that the losers of each round "drop down" into the L bracket.
The final winner is the winner of the match opposing the two brackets winners.

A round-robin tournament (or all-play-all tournament) is a competition in which each contestant meets every other participant once, in turns.
