Tournament bracket generator

Paste a list of participants to instantly generate a single-elimination bracket with randomly drawn matchups. Click a name to advance it to the next round. Nothing is sent to a server: everything happens in your browser.

Example:
The number of participants doesn't have to be a power of 2: byes will be added automatically.

How it works

Handy for organizing a sports tournament with friends, a video game competition or a ranking at school, this tool randomly draws the matchups and automatically builds the following rounds as you pick the winners.

What happens if the number of participants isn't a power of 2?

Byes are added automatically to fill the bracket up to the next power of 2 (4, 8, 16, 32...). Participants with a bye move straight to the next round without playing a match.

Is the draw fair?

Yes, the order of participants in the bracket is randomly shuffled each time you generate it, so the starting position doesn't favor anyone.

The list of participants stays on your device: no data is sent to a server.
