This is the first time I hear about Gamebetr. Don't you mean Playbetr? Playbetr used to have their own site but merged with Betcoin some time ago. I remember it from my withdrawal fees thread. Betcoin uses the betcoin.ag domain, while Playbetr got redirected to new.betcoin.ag. Even if you try to access playbetr.com noew, it will redirect you to the new Betcoin domain.
