EuroLeague is widely regarded as the top club basketball competition in Europe. This explainer covers its structure and how a season builds toward a single championship weekend.

A competition with deep roots

European club basketball has a long history, with continental competition tracing back to the European Champions Cup in the late 1950s. The modern EuroLeague has been reshaped several times and today features clubs from across the continent.

The regular season

In recent seasons the competition has used 18 clubs in a double round-robin: each club plays every other club home and away, giving 34 games per club. Clubs enter through a mix of long-term licences and sporting qualification, so the field can change from year to year.

Play-in and playoffs

  • Top six: advance directly to the playoffs.
  • Seventh to tenth: play a play-in tournament for the final two playoff places.
  • Playoffs: quarter-finals are played as a best-of-five series, with the higher seed hosting the first, second and fifth games.

Why best-of-five matters

A longer series rewards consistency and depth. It also means home-court advantage can be decisive, which gives the regular season real stakes.

The Final Four

The four surviving clubs travel to one host city for semi-finals and a final over a single weekend. Single-elimination games create a very different atmosphere from the regular season, and arenas are often filled with passionate supporters from every finalist.

Other European competitions

EuroLeague is not the only European club competition. EuroCup acts as a second tier, and FIBA organises the Basketball Champions League. Many clubs also play in domestic leagues in Spain, Turkey, Greece, Italy, Germany and elsewhere, which feed players and storylines into European play.

Always verify the current rules

Format details such as club numbers and playoff structure are decided by the organiser and have changed before. Treat this article as an overview and check the official competition site for the current season.
