Seeded, with every game numbered. 27 games. Free PDF, no ads, no sign-up.
With 28 teams, seeds 1-4 get a bye and skip the first round. Seeds 5-28 play 12 opening games, and the winners move on to face the top seeds.
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 27 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.
