The tournament is loosely similar to the FIFA Club World Cup in association football, however participating teams are not regional champions, instead entering via invitation.

Portuguese and Russian sides Braga and Lokomotiv Moscow are the most successful teams with two titles each.

[2] In the first two editions (2011 and 2012), squads were specially assembled to represent well known association football clubs from around the world – these teams were incarnated purely to compete in this event.

[3] Players of many nationalities (of which they were considered the best of) were invited to play; they were then allocated to one of the clubs specifically for the purpose of the event using a draft system conducted by BSWW.

In the next two editions (2013 and 2015), the clubs and their squads that competed either already exist beforehand (i.e. competed in a domestic club league in their country) or remained specially assembled purely for the competition, but now with squads materialised behind the scenes with players choosing to play for said team at their own discretion rather than via a draft.
