Format
There were two divisions. In Division 1, the top twelve teams from the World Championships played. They played all matches in March in Zagreb and Podgorica. All other teams could have signed up in Division 2, in which each continent hosted a qualification tournament. The top two teams from each of those tournaments played in an intercontinental tournament. The top-six teams of Division 1 and the top-two teams from Division 2 competed in the super final, held from 30 June to 2 July 2023. At the end of the tournament, the last-ranked team was relegated to Division 2 and the winner of Division 2 moved to Division 1 for the following year. A win gave a team three points, a win after penalties two, a loss after penalties one and a loss after regular time zero points.
