About This Tool
Introduction
A bracket generator turns a list of names into a tournament in seconds — and Trencada's free Bracket Generator handles everything from a 4-player game night to a 32-team office pool. Paste one name per line, pick random shuffling or your own seed order, and get a clean single-elimination bracket sized to the next power of two. Odd player counts get BYE spots whose opponents advance automatically, and clicking any participant's name advances them through the rounds to a champion banner. Perfect for sports pools, esports, board-game nights, and playground tournaments. Everything runs entirely in your browser with no signup.

Frequently Asked Questions (FAQ)
- What happens with an odd number of players? The bracket rounds up to the next power of two (4, 8, 16, or 32) and the empty slots become BYEs. Players drawn against a BYE advance automatically, exactly like real tournaments.
- Can I change a winner after clicking? Yes — just click the other participant's name in that matchup. Later rounds recompute automatically from the corrected result.
- What's the difference between Generate and Reshuffle? Generate builds a bracket from the names you entered (shuffled or in order, per the checkbox). Reshuffle keeps the same names but redraws with a fresh random order.
- Do I need to create an account? No. Like all Trencada tools, it works instantly with no signup or login.
- Is my data private? Yes. The tool runs entirely in your browser — no names or results leave your device.
