The South Florida Kickball Open (SFKO), presented by The IKF, is a national tournament that is open to kickball teams from all over the world. It is a Circuit Event which is an open tournament, meaning that teams do not have to be invited nor otherwise qualify in order to take part in the tournament – any kickball team can register to play. In fact, a team does not even have to be part of any official, organized kickball league, national or otherwise. Anyone can create a team and register that team to play. The only requirements are that teams must field 10 players with at least 4 members of each sex, and all team members must be at least 21 yrs or older on the day of the tournament.
