The shape of a 12-team bracket

12 teams in a 16-slot bracket leave 4 byes, for seeds 1 to 4. The other 8 teams play 4 round-1 games: 8 v 9, 5 v 12, 7 v 10 and 6 v 11. After round 1, 8 teams are left and the bracket is full from there.

If the favourites win

That puts seed 1 against seed 4 and seed 2 against seed 3 in the semifinals.

SeedOpponents if favourites win (game)
1bye, then 8 (G5), 4 (G9), 2 (G11)
2bye, then 7 (G7), 3 (G10), 1 (G11)
3bye, then 6 (G8), 2 (G10)
4bye, then 5 (G6), 1 (G9)

How many games each team plays

The fewest is 1, for a team that loses its first game, which for a bye team is its round-2 game. The most is 4, and 3 for a champion that had a bye. In the favourites-win run, seed 1 plays 3 and seed 12 plays 1.

How long it takes

11 games at 30 minutes is 5 h 30 min of court time. No round has more than 4 games, so extra courts beyond that sit idle.
