How to play
- Type or paste one player or team name per line (4–32 total works best).
- Choose whether to randomize seeding, then tap Build bracket.
- Tap the winning name in each match to advance them to the next round.
- Once every round is decided, the champion appears in its own card — print or share to wrap up.
Paste in your list of players or teams, one per line, and this tool lays out a full single-elimination bracket in seconds, automatically adding byes when the count isn't a clean power of two. Turn on random seeding to shuffle the field fairly, or leave it off to bracket people in the order you typed them. Tap a name to advance them to the next round; the bracket redraws instantly and the champion's name lights up in its own card once the final is decided. When you're ready to run the day, print the bracket or share the screen so everyone can see who plays who next.
Frequently asked questions
- What happens if I don't have a power-of-two number of players, like 6 or 11?
- The bracket automatically adds byes so the numbers work out. Players with a bye skip round one and move straight into round two — no blank matches to manage by hand.
- Can I change a winner after I've already tapped one by mistake?
- Yes. Tap the other name in that match to switch the pick — any later rounds that depended on the old winner are automatically cleared so the bracket stays consistent.
- Does it support double elimination?
- This version builds single-elimination brackets, which cover most pickup tournaments and party games. Every player is out after one loss, keeping the whole event fast to run.
