The team in each section winning the greatest percentage of games will be declared the winner in that section. In case two or more teams tie for first place in the percentage of games won, a set of semi-finals will be arranged. The winners in each of the three sections will play a round of games for the championship; the team winning the greatest percentage of games to be declared the champions and to receive the cups.
