The tournament is organized by the USITA, an organization formed to promote fee-based internet tournaments of all types. USITA has an agreement with Game Colony to host all tournaments.
You must be a member of Game Colony (membership is free) to join USITA. Being a member of USITA will not guarantee you entry into tournaments (entry into tournaments will be on a first-come basis) but you must be a member of USITA to participate in USITA tournaments hosted by Game Colony.
In addition to the U.S. Open Domino Championship, the USITA hosts 12 online tournaments every month, with low entry fees and great cash prizes.
