It depends on where you’re connecting from. In Grand Theft Auto 5, access to the
Diamond Casino & Resort is restricted in some countries due to local gambling laws. In those regions, casino games may be disabled even though the building itself is accessible. A VPN can change the location your connection appears to come from, which may allow GTA Online to load casino features when you’re connecting through a country where the Diamond Casino is supported. However, access is still governed by the
Rockstar Games legal and regional rules, and results can vary. A VPN doesn’t change your Rockstar account details or local laws. It only affects your network location.
