The teams were divided into three groups of four, according to geographical criteria. All teams play eight games during the regular season: two games (home and away) against each other team in their group, plus two inter-group games (against one team of each other group).
At the end of the regular season, the eight best teams in the aggregate table qualify for the playoffs.[1] Final position in the aggregate table will determine seeding for the playoffs.
