In the 2012–13 season, the final was decided by a single game format, after double-legged semifinals and quarterfinals. For the 2013–14 season, the competition increased from 32 to 48 teams in the Regular Season phase. Another innovation that started in the 2013–14 season, was that the clubs were divided into two regional conferences, the Eastern Conference and the Western Conference, for the Regular Season phase. The size of the groups grew to six teams, where the first three qualified teams joined the Last 32 stage. In addition, the eight EuroLeague clubs that did not qualify for the EuroLeague Top 16 phase, joined the remaining 24 EuroCup teams and the Finals were decided by a double-legged series.
