The first phase is a regular season, in which the competing teams are drawn into three groups, each containing eight teams. Each team plays 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 advance to the next round. The complete list of tiebreakers is provided in the lead-in to the Regular Season results.
If one or more clubs are level on won-lost record, tiebreakers are 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 are 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, advance to Top 16
The surviving teams are divided into four groups of four teams each, and again a round robin system is adopted resulting in 6 games each, with the top team advancing to the Final Four. Tiebreakers are identical to those used in the Regular Season.
