How it works
A 12 team tournament bracket, single elimination, gives Seeds 1 to 4 a bye and sends Seeds 5 to 12 into four opening games. Each winner walks into a quarterfinal against a seed that has not played yet. Eleven games, four rounds, one champion.

Four byes, and who each top seed meets
Twelve is four short of 16, so a third of the field skips round one. The winner of 8 v 9 meets Seed 1, of 5 v 12 Seed 4, of 6 v 11 Seed 3 and of 7 v 10 Seed 2. A top-four seed wins the title in three games; everyone else needs four. The line between fourth and fifth is worth a whole round, so break ties for it in public.
Two courts, three courts, four courts
One court needs 11 slots, two need 6, three 5 and four 4. No quarterfinal can start early: each waits on an opening game. On two courts, number order gives every opening-round winner a slot off before its quarterfinal, but Game 10 and the final follow straight on. Put breaks there.
- From four pools of three, seed winners and runners-up in pool order A, B, C, D as Seeds 1 to 8 and thirds B, A, D, C as Seeds 9 to 12. No pool game can repeat before the semifinals.
- Type names to fill it in on screen; with none entered it prints as a blank 12 team tournament bracket template. Print two: one for the wall, one for the scorer's table.
- Want every winner to rest a slot between games? Two or three courts then need 8 slots, four courts 7.
Questions and answers
Is single elimination the right tournament bracket for 12 teams?
It is the quickest: 11 games, against 66 for a 12 team round robin. The cost: at least four teams are out after one game, up to eight if top seeds lose their quarterfinals. The 12 team double elimination bracket guarantees every team two games.
Does it work as a 12 player tournament bracket?
Yes. A 12 person tournament bracket, or 12 man bracket, for singles pickleball, darts or cornhole has one name per line and 11 matches. With no rankings, press Random draw with everyone watching: whoever lands on Seeds 1 to 4 skips a round.
What changes with 11 teams, or 13?
Set the Teams box to either number: names stay, results clear. With 11, Seed 5 gets a fifth bye and goes straight into a quarterfinal against Seed 4: 10 games. With 13, Seed 4 loses its bye and plays Seed 13 in a fifth opening game: 12. For a dropout, delete its line from Names first.
