Then someone loses their first match.
If the player coming from the Losers Bracket beats the undefeated player in the first Grand Finals match... it means everyone has one loss. The bracket resets. You play one final, winner-take-all match.
In a manual bracket, this is a disaster. In a digital bracket maker? You click one button, and the new final match appears automatically. Stop messing with spreadsheets and crooked printer paper. Whether you are running a charity e-sports event, a backyard BBQ beer pong tournament, or a serious chess club showdown, a Double Elim Bracket Maker is your best friend.
Time warning: Double elim takes almost twice as long as single elim. Plan your schedule accordingly! The best part of the double elim system is the potential for the Bracket Reset .
