The scheme exists to help people manage their gambling, and if you registered during a period of concern about your habits, seeking support may be more beneficial than looking for alternatives. The responsible gambling organisations listed at the end of this guide are available to help. 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.
