How double elimination works
Every team starts in the winners bracket. A first loss drops a team into the losers bracket. A second loss eliminates it. The winners-bracket champion meets the losers-bracket champion in the grand final.
Bracket reset
Because the winners-bracket champion has not lost yet, some rules require a reset final if the losers-bracket champion wins game one. Turn on Add a reset final to play that second game. With it on, the champion is guaranteed to have at most one loss. With it off, the grand final is a single decider.
Byes
Non-power-of-two fields round up to the next bracket size. Byes go to the top seeds in the winners bracket. A bye never counts as a loss, and an empty losers-bracket slot is skipped automatically.
8-team example
An 8-team double elimination bracket has 7 winners-bracket matches, 6 losers-bracket matches, and 1 grand final: 14 matches without a reset. If the losers-bracket champion wins game one and a reset is enabled, the bracket plays a 15th match.
What gets cleared when you change a result
Every match has two outgoing paths: its winner and its loser. Changing a result clears every result reachable through those paths. That includes later winners-bracket rounds, losers-bracket rounds, and the grand final. The bracket skeleton stays in place, so you can re-enter the new path.
