DOUBLE-ELIMINATIONTOURNAMENT
DOUBLE-ELIMINATION TOURNAMENT
a type of elimination tournament competition in which a participant ceases to be eligible to win the tournament’s championship upon having lost two games or matches.
It stands in contrast to a single-elimination tournament, in which only one defeat results in elimination.
Purpose: All contestants remain in championship contention until they lose two games
Advantages:• A player or team must be beaten twice to be
eliminated• It selects a more adequate winner• It maintains player motivation right up until the
end
Disadvantages• It takes longer to run• It emphasizes elimination
Instructions• Formula – min # of games: (N-1) 2Max # of games: 2(N-1) + 1• Construct a single elimination tournament with
appropriate # of slots• Close the blocks of first round• Complete the “losers side” Note – every odd # round should have the same # of
slots as the previous round• Criss cross losers so they don’t play the same team
again.
• One method of arranging a double-elimination tournament is to break the competitors into two sets of brackets, the Winners Bracket and Losers Bracket
