Not all VPN methods are suitable for all games. Below guidelines won't apply to every single game out there, but they're a good starting point.
Web based games are the easiest - they work with any VPN method that your browser works with.
The same usually applies to turn-by-turn games: they typically work with any VPN method. There may be exceptions.
Real-time games perform best when used with a UDP based VPN method. This includes:
Our VPN whitelists most well-known game publishers. This means that their games are allowed unrestricted Internet access through the VPN, including the use of ports which we would otherwise consider dangerous.
Lesser known game publishers may be missing from our whitelist. And as well-known publishers make changes, they too, may not be completely whitelisted. If you suspect this to be the case, please let us know which games is failing and we'll update the whitelist.
Note that whitelisting only applies to the UDP based VPN protocol mentioned in the Real-time games section above. If you have trouble with a turn-by-turn game you may want to try the recommendation under real-time games before contacting us.
