A tournament bracket generator places teams into a single-elimination tree. One loss ends a run, and the champion is the team that wins every round. This one builds a blank bracket for 4, 8, 16, 32, 64 teams. The default is 8 teams, tournament seeding, and shuffle off. A copied opening match reads 1. Seed 1 vs Seed 8. Later rounds say Winner and a match id. The generator does not pick a winner.
Line order is the seed order. Seed 1 plays the lowest seed, and seeds 1 and 2 are in opposite halves, so they can meet only in the championship if both keep winning. Adjacent seeding instead pairs line 1 with line 2 and line 3 with line 4. A blank line becomes TBD. Extra lines past the selected size are left out. Because every size is a power of two, nobody has a bye. The number of matches is one less than the number of teams.
The 2026 NCAA Division I men's tournament used 68 teams, 31 automatic qualifiers and 37 at-large teams, then a First Four. Michigan beat UConn 69-63 on April 6, 2026, at Lucas Oil Stadium in Indianapolis, for the program's first title since 1989. The 64-team option here is one tree. It does not split the field into four regions or build the First Four. In 2027 the men's and women's fields expand from 68 to 76, and 64 teams remain after the opening round.
Choose a size
The menu starts at 8 teams. The choices are 4, 8, 16, 32, 64.
Paste one team per line
The first line is seed 1 when tournament seeding is on. Empty lines become TBD. Shuffle mixes the order before the bracket is built.

Seeds 1 and 2 are in opposite halves. If the higher seed wins every game, seed 1 meets seed 4 in one semifinal and seed 2 meets seed 3 in the other.
=== Quarterfinals === 1. Seed 1 vs Seed 8 2. Seed 4 vs Seed 5 3. Seed 2 vs Seed 7 4. Seed 3 vs Seed 6 === Semifinals === 1. Winner — R0-M0 vs Winner — R0-M1 2. Winner — R0-M2 vs Winner — R0-M3 === Championship === 1. Winner — R1-M0 vs Winner — R1-M1
