How does double elimination work?
Double elimination gives every team a second life. A first loss does not send you home — it sends you to a second bracket. Here is how the winners bracket, losers bracket, and grand final fit together.
Double elimination gives every team a second life. A first loss does not send you home — it sends you to a second bracket. Here is how the winners bracket, losers bracket, and grand final fit together.
A double-elimination tournament runs two brackets at the same time. The winners bracket looks exactly like a normal single-elimination bracket. The losers bracket is where teams go after their first loss, so they can keep playing instead of being eliminated.
A team is only knocked out after losing twice — once to drop out of the winners bracket, and once more to be eliminated from the losers bracket.
The losers bracket has to absorb teams dropping down from every winners-bracket round. So it alternates between two kinds of rounds: a round where existing losers-bracket teams play each other, then a round where the winners of those games meet the newest batch of teams that just lost in the winners bracket.
That back-and-forth is why the losers bracket runs for roughly twice as many rounds as the winners bracket, even though each round is smaller. A good generator handles this routing for you, so you never have to redraw the losers side by hand.
The grand final is the winners-bracket champion against the losers-bracket survivor. There is a catch worth knowing: the winners-bracket team has zero losses, while the losers-bracket team already has one.
In a strict bracket-reset format, if the losers-bracket team wins the grand final, both teams now have one loss, so a second deciding game is played. Many casual events skip the reset and treat the grand final as a single game. Decide which version you want before the tournament starts so nobody is surprised.
Running a bracket on site is easier with a printed scoresheet, a clipboard, and lineup cards within reach.

Your first loss does not eliminate you. Instead you drop into the losers bracket and keep playing. You are only out of the tournament after a second loss.
The grand final is the last match, between the undefeated winners-bracket team and the team that survived the losers bracket. In a true bracket-reset format, if the losers-bracket team wins, a second deciding game is played because both teams then have one loss.
It has to absorb teams dropping down from every winners-bracket round, so it alternates between rounds that play existing losers-bracket teams and rounds that add the newest winners-bracket losers. That makes it roughly twice as many rounds as the winners bracket.
The generator builds both brackets, routes every loser to the right spot automatically, and runs the grand final — all in your browser.
