The championship is the sport's version of the better known UEFA Champions League in association football.

[1] Organised by Beach Soccer Worldwide (BSWW), the tournament was held in Nazaré, Portugal, from 25 May till 3 June 2018, consisting of a preliminary qualifying round and the competition proper.

At its conclusion, the best teams progressed to the knockout stage, a series of single-elimination games to determine the winners, starting with the round of 16 and ending with the final.

Each club must submit a squad of a maximum of 12 players that includes a minimum of two goalkeepers.

[16] To protect the competition's original purpose as a championship primarily for Europe's league champions, BSWW made changes ensuring that this year only two quarter-finalists and subsequently one semifinalist would be non-champion qualifiers from the preliminary round.

[16][7] This was later revised so that only one team in the quarter-finals would be a qualifier, whilst the other seven would be guaranteed to be a league champion.

[17] This season, embedded within the wider scope of this edition of the Euro Winners Cup, an additional tournament will be taking place.

The best two teams of the second group stage advanced to the final that took place as part of the round of 16 of the EWC.

[16] However the format was later revised; only the winners of each group (two clubs) now advance to play in the knockout stage.

Consolation matches are also played to determine the final rankings involving the clubs knocked out of each round of the knockout stage.
