The first phase was a regular season, in which the competing teams were drawn into three groups, each containing eight teams. Each team played every other team in its group at home and away, resulting in 14 games for each team in the first stage. The top 5 teams in each group and the best sixth-placed team advanced to the next round. The complete list of tiebreakers was provided in the lead-in to the Regular Season results.
If one or more clubs were level on won-lost record, tiebreakers were applied in the following order:
Head-to-head record in matches between the tied clubs
Overall point difference in games between the tied clubs
Overall point difference in all group matches (first tiebreaker if tied clubs were not in the same group)
Points scored in all group matches
Sum of quotients of points scored and points allowed in each group match
Key to colors
Top five places in each group, plus highest-ranked sixth-place team, advanced to Top 16
The surviving teams were divided into four groups of four teams each, and again a round robin system was adopted, resulting in 6 games each, with the top team advancing to the Final Four. Tiebreakers were identical to those used in the Regular Season.
