The tournament featured three rounds of play. In the Quarterfinals, teams played a two-game series where the first team to reach 3 points was declared a winner (2 points for winning a game, 1 point each for tying). If both teams ended up with 2 points after the first two games a 20-minute mini-game used to determine a winner. Mini-game scores are in italics. Beginning with the semifinals all games became Single-game eliminations. The winning teams in the semifinals advanced to the National Championship Game with the losers playing in a Third Place game. The teams were seeded according to geographic proximity in the quarterfinals so the visiting team would have the shortest feasible distance to travel.
