How to Run a Tournament Bracket

A bracket turns a pile of players into a champion. Doing it by hand means drawing lines, erasing names and getting the byes wrong. The Tournament Bracket builds it for you, any size. This guide covers the setup decisions that actually matter.

Step 1 — Choose the format

Single elimination is fastest: lose once and you're out. Perfect for a lunchtime FIFA tournament or a quick office Smash Bros. crown. Double elimination gives everyone a second life so one bad match doesn't end an early favourite, at the cost of roughly double the matches. For most casual events, single elimination with randomised seeding is right.

Step 2 — Seed or randomise

Seeding places the strongest players apart so the two best meet only in the final. It's fairer to the favourites but predictable and can feel elitist. Randomising the whole draw is simpler and more exciting: anyone can get a brutal first round. Either is defensible — just pick one and announce it before the draw so nobody accuses you of engineering easier matchups.

Step 3 — Handle byes

If your player count isn't a power of two (4, 8, 16, 32), some players get a first-round bye. The generator assigns byes automatically and distributes them so they're spread across the bracket rather than dumped on one side. Don't do this by hand — misassigned byes are the number-one way to make a bracket unfair.

Step 4 — Run the matches

Advance winners into the next round as results come in. The bracket updates visually, so everyone can see who's next. Post the link (copy it) so players check their own matches instead of asking you.

Tie-breaks

Every tournament needs a tie rule decided up front. For games with scores, use goal differential. For anything else, replay the deciding match, or highest seed advances, or — most cleanly — a single coin flip, decided in public. Pick one rule and apply it consistently; inconsistency in tie-breaks is what turns a fun bracket into an argument.

Player counts

Big gaps in bye counts are normal and fine — the goal is equal opportunity to win the event, not the same number of matches per person.
