Bracket & Sweepstake Generator
Bracket & Sweepstake Generator sets up your competition in seconds. Bracket mode shuffles any list of teams or players into a random single-elimination bracket — quarter-finals, semi-finals and final — with byes placed automatically when the numbers don't divide evenly. Sweepstake mode runs the classic office draw: it deals the teams out fairly among your participants, perfect for a World Cup, March Madness or fantasy-league kickoff. Draws are powered by the cryptographically-secure Web Crypto API, so they're genuinely fair.

A bracket generator draws a random single-elimination tournament from any list of teams or players — enter one per line and it shuffles them into fair matchups with byes handled automatically, from the first round to the final. Sweepstake mode instead deals the teams out evenly among the people in your office or family draw. Both use the cryptographically-secure Web Crypto API and run entirely in your browser.
Cómo usar Bracket & Sweepstake Generator
- Choose Bracket or Sweepstake mode.
- Paste your teams (and for a sweepstake, your people), one per line.
- Hit Draw, then copy the bracket or assignments to share.
Preguntas frecuentes
How do I run a World Cup sweepstake?
Switch to Sweepstake mode, paste the teams in one box and the people taking part in the other, and hit Draw. Teams are dealt out round-robin after a crypto-secure shuffle, so counts differ by at most one and nobody can rig it. Copy the result and share it with the group.
What if my team count isn't a power of two?
Bracket mode pads the field with byes up to the next bracket size (4, 8, 16, 32…), so an odd field like 6 or 12 teams still produces a clean knockout bracket.
Is the draw actually random?
Yes — shuffles use the browser's Web Crypto API (the same randomness source used for cryptography), not a predictable pseudo-random trick.
Can I redo the draw?
Hit Draw again for a fresh shuffle. If the group wants a witnessed draw, do it once on a shared screen — nothing is stored, so each draw is final unless you re-run it.
Is my list uploaded?
No — the draw happens entirely in your browser. Your teams and names never leave your device.
