Tournament Bracket Generator
Set up a fair knockout tournament in seconds. Paste your players or teams, one per line, and the generator randomly seeds them into a single-elimination bracket — handling byes automatically when the count isn't a power of two.

How single-elimination brackets work
A single-elimination (knockout) bracket is the simplest fair tournament format: every match has a winner who advances and a loser who's out, so the field halves each round until one champion remains. The number of slots must be a power of two — 4, 8, 16, 32 — because each round needs to pair everyone up cleanly. When your entry count isn't a power of two, the standard fix is a bye: a player is given an automatic pass to the next round. A 6-player event rounds up to an 8-slot bracket with 2 byes; a 10-player event becomes 16 slots with 6 byes. This generator handles that arithmetic for you and assigns the byes so the bracket stays balanced.
Seeding fairly — and when to use it
In professional tournaments, top players are seeded apart so the best don't meet in round one. For a casual event, a random draw is usually fairer and more fun — nobody can claim the bracket was rigged, and upsets become part of the story. That's what this tool does: it shuffles every entrant with a cryptographically secure random source (the unbiased Fisher–Yates shuffle) before placing them. Single-elimination is ideal when you're short on time, since an n-player event needs only n−1 matches total. If you'd rather give everyone more games, consider a round-robin or double-elimination format instead. To split a big group into squads first, try our team randomizer or random group maker.
Frequently asked questions
What if I don't have a power-of-two number of players?
The generator rounds up to the next power of two (4, 8, 16, 32…) and hands out byes — automatic free passes to round two — so the bracket stays balanced. With 6 players you'll get 2 byes.
Is the seeding random?
Yes. Players are shuffled with crypto.getRandomValues before being placed, so the draw is genuinely fair and nobody can predict the matchups.
What's a single-elimination bracket?
A knockout format: lose once and you're out. It's the fastest way to crown a winner and is used in everything from tennis Grand Slams to office ping-pong ladders.
Can I reshuffle?
Yes — press Generate again for a brand-new random draw. Each press produces an independent fair seeding.
