Regarding the Losers Bracket Update

While the losers bracket update was an improvement, I finally realized a few key concepts that will help me finalize the bracket. It's all figured out in my head... now for the tedious part.

Double Elimination Loser Bracket v2

While I can't claim to have addressed every losers bracket scenario perfectly, I think the latest update corrects a lot of the scenarios, especially for large brackets. There's no way to avoid rematches for some bracket sizes, but the "standard" sizes (4,8,16,32,64,...) and most variants should be smarter than before.

Existing tournaments will not be affected by this update, but all new tournaments and bracket generator output will reflect the new algorithm.

Special thanks to Pierre and Esteban for identifying some of the losers bracket seedings that didn't look quite right. I'm not 100% content with the changes this update enforces, but I think the algorithm is more reliable than the current one.

Thanks for using Challonge! There's plenty more to come, and I appreciate your support. Please feel free to contact me with your comments by following the Contact/Support link at the bottom of

! Double Elimination Brackets !

I finally got around to applying the new look to double elimination brackets. There are bound to be a few flitches to work out, but I'm pleased that this feature is out the door at last.

Next, I'll be revisiting the seeding logic for losers brackets. Scenarios for large tournaments have been brought to my attention (thanks!) where rematches aren't avoided as much as is possible. Tournament open sign-ups are also near the top of the queue.

A Tweak or 2

Tournament participants can now set their names for each tournament instead of being restricted to a single name per account. This allows a participant to provide a game specific alias or team name that will show up in the brackets.
