After the
2017–2018 season, the Balkan International Basketball League introduced a new, simplified competition format. Under this format, the competition typically features between 6 and 8 teams. The tournament is divided into two phases: the regular season, where all participating teams play each other in a double round-robin format, both home and away. Following the conclusion of the regular season, the first- and second-placed teams automatically qualify for the
Final Four. The third-placed team plays the sixth-placed team, and the fourth-placed team plays the fifth-placed team in home-and-away games to determine which teams will advance to the Final Four. The winning teams from these matchups then advance to the Final Four to compete for that season's BIBL Balkan League championship. Additionally, at the start of the
2020–2021 season, 12 teams from
Israel participated in the league to ensure access to competitive games during the
COVID-19 pandemic. ==Championships==
