Seeded, with every game numbered. 63 games. Free PDF, no ads, no sign-up.
With 64 teams every team plays in the first round, so there are no byes. Seed 1 plays seed 64, seed 2 plays seed 63, and so on.
It's single elimination: lose once and you're out. Seeds 1 and 2 start on opposite halves, so they can only meet in the final. The bracket has 63 games over 6 rounds. Every game is numbered, so you can call games, assign courts, and keep score by game number.
Game numbers match SportsGrove's brackets and the common printable sheets, so a printed copy lines up with a bracket you run online.
