How Does a 12 Team Single Elimination Tournament Work?
12 team single elimination (or knockout) tournament consists of 4 rounds and has 11 games in total.
Bracket Size
The bracket size is determined by rounding up to the next power of 2 after the number of teams. For 12 participants, the bracket size is 16.
Byes
Byes are the difference between 16 and 12, so there are 4 byes in this tournament.
Rounds & Games
There are 4 rounds and 11 actual (non-bye) games in the 12-team single elimination bracket:
- Round of 16: 4 real games and 4 byes
- Quarter-Finals (Round of 8): 4 games, 8 teams
- Semi-Finals: 2 games, 4 teams
- Final: 1 game between 2 teams
Seeding
