The tournament featured four rounds of play. All rounds were Single-game elimination.
Because fewer than four western teams qualified, the tournament was arranged so that all western teams were placed into one quarterfinal bracket. The nine eastern qualifying eastern teams were arranged evenly across the remaining three quarterfinal brackets. The top three eastern seeds and the top western seed received byes into the quarterfinal round and were arranged so that the bracket containing the top overall seed would play the bracket containing the third eastern seed.
The six eastern teams in the quarterfinals were arranged so that the fourth- and ninth-seeded teams would play with the winner advancing to play the third eastern seed, the fifth- and eighth-seeded teams would play with the winner advancing to play the second eastern seed and the sixth- and seventh-seeded teams would play with the winner advancing to play the first eastern seed. The second and third western teams would play in the first round with the winner advancing to face the top western seed.
In the First Round and Quarterfinals the higher-seeded team served as host.
