If you’re registered with GamStop and looking to continue gambling, non GamStop casinos are not part of the scheme and therefore do not check against the GamStop database when you register. This means that creating an account at a non GamStop casino is not blocked by your GamStop registration.

The most common of these is Curacao, where the Curacao Gaming Control Board issues licences to operators based in or operating from that jurisdiction. Non GamStop Curacao casinos are among the most numerous in the offshore space.
