World Sport Stacking Association
As the official, worldwide governing body for sport stacking, the World Sport Stacking Association (WSSA) promotes the standardization and advancement of sport stacking rules, records and events. The WSSA was formed in 2001 as the World Cup Stacking Association but in 2005, both the name of the sport and the organization were changed in response to growing awareness that stacking had become an actual school-based sport. Sport stacking is now part of over 47,000 school and club programmes in 54 countries worldwide.
