The John Stuart Mill Cup follows a regionals-and-finals format. Every registered team will compete initially in a 12-team regional tournament. Three teams will advance to the finals from each regional: both teams that make it to the championship match, plus the team that wins the third place playoff. Since there are four regionals and three teams advancing from each, the finals will be a 12-team tournament.
