Why use a tournament bracket?
Whether it's a FIFA tournament with friends, an office ping-pong championship, a family card game night or a local e-sport event, an elimination bracket is still the clearest, fairest and most thrilling way to crown a winner. This generator builds a complete bracket in seconds — no account, no app install, no spreadsheet pain.
Each match is clickable: pick the winner, the bracket updates, losers flow to the right place (gone in single elimination, loser bracket in double), and the ranking recomputes live. Your tournament is saved in your browser — close the tab and come back later.
Single vs double elimination
Single elimination: lose once, you're out. Fast, punchy, perfect for an evening that must fit in 1–2 hours. Downside: one bad game is enough to knock out a favourite.
Double elimination: every player gets a second chance. Losers drop to the loser bracket. Win them all and you earn a ticket to the Grand Final against the undefeated winner-bracket champion. Almost double the matches but far less luck-dependent — the gold standard for serious competitions (fighting games, wrestling, darts, Dota 2…).
How are odd player counts handled?
A clean bracket needs a power of 2 (2, 4, 8, 16, 32…). With 7 players, the tool auto-inserts a Bye to reach 8. Anyone drawn against a Bye advances without playing. In double elimination, Byes are also handled in the loser bracket so you never have to click phantom matches.
Seeding, shuffle and balancing
By default, "Shuffle randomly" is on: it mixes the list before seeding, so the top 4 of an already-ranked list don't meet in round 1. If you've crafted a specific seeding with favourites split apart, untick the box — your exact order is respected.
Good practice for a great tournament
- Cast to a TV so everyone follows the action live.
- Agree on match rules upfront (best-of-3, first to 11, time-capped…). The tool doesn't enforce them.
- Name players unambiguously: "Alex D." vs "Alex M." saves confusion.
- One click fixes mistakes: pick the correct winner, the bracket recomputes.
Round naming
Rounds are auto-labelled by distance to the final: Round 1, Quarterfinals, Semifinals, Final. Same logic for the loser bracket, prefixed LB. No naming headache.
FAQ
What's the difference between single and double elimination?
In single elimination, one loss ends your tournament: fast but luck-sensitive. In double elimination, every player gets a second chance in a loser bracket — you can lose once and still reach the Grand Final. Fairer but almost doubles the number of matches.
What happens with an odd number of players?
The generator adds automatic Byes to reach the next power of 2 (8, 16, 32…). Players drawn against a Bye advance for free. In double elimination, Byes are also handled in the loser bracket to avoid phantom matches.
Can I change a result after the fact?
Yes. Just click the other player in the relevant match — the whole bracket recomputes, including later rounds, the ranking and the Grand Final. Any match played further along with the old winner is cleanly reset.
Is my bracket saved if I close the tab?
Yes. The whole tournament state (list, format, match results, ranking) is saved locally in your browser. Close the tab, shut down the computer, come back tomorrow — you'll resume exactly where you left off. Nothing is sent to our servers: your data stays with you.
What's the maximum number of participants?
No hard limit. The tool is tested up to 128 participants (a full e-sport bracket size). Beyond that, the bracket just gets wide — use horizontal scroll. For readability, aim for 64 or less, or use a wide screen.
Should I enable "Shuffle"?
Yes, unless you've built a deliberate seeding. If your list is already ranked (best at top), shuffling prevents the top 4 from meeting in round 1. If you've carefully split favourites so they only meet in the final, untick the box: the input order is respected as-is.
Is it free? Is there a usage limit?
Completely free, no signup, no account, no usage cap. Create as many brackets as you want, regenerate them, share them (screen share). Outilo is funded by discreet ads, keeping the tool fully open.
