Seeded, with every game numbered. 30 games. Free PDF, no ads, no sign-up.
With 31 teams, seed 1 gets a bye and skips the first round. The other 30 teams play 15 opening games.
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 30 games over 5 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.
