Since then, one other world championship game was held in 2013, also at Weissensee, Austria. Both of these matches were organized by founder Christian Redl in hopes of furthering the sport, and over the last 12 years, Redl has been successful in bringing this minor extreme sport to the world; however, due to the nature of the activity, it is still limited to extreme sport enthusiasts and apnea divers. Historically, the aspect of the game that has drawn a lot of apnea divers, especially apnea divers under ice, is the conditions in which the sport is played.
