The league champions and cup winners from four countries take part. If the same team wins the league and the cup in their country, the second-place team in the league also takes part.
For quarterfinals the eight teams are divided into two conferences based on their geographical location. The Swedish and Finnish teams take part in the Northern conference; the clubs from the Czech Republic and Switzerland play in the Southern conference. The four winners advance to the semifinals. Quarterfinals and semifinals are played in a home and away format. If a round is undecided after the two matches, the second match is followed by an overtime. The two semifinal winners play in a final held at a centralized venue.
