12 Team Single Elimination Bracket
Create a 12-team single elimination bracket with automatic bye handling in a 16-slot tree and live voting on every knockout matchup.
Start here — build your bracket
Twelve entries expand to a sixteen-slot knockout bracket with four byes for top seeds — the same structure many leagues use when registration lands between eight and sixteen teams. Live voting opens each round without spreadsheet re-seeding.
Use this page when your division has twelve squads and you want a fair knockout path without cutting four teams before bracket day.
For single elimination events, confirm your audience understands the format before voting starts — especially if you are mixing casual voters with experienced competitors. A one-sentence rules recap at the top of the session reduces mistaken votes and keeps the bracket moving. Save a screenshot of the final tree for recaps, newsletters, or league records.
