Though we are lucky because our government isn't having us banned or restricted but for those who lives in restricted countries they have no choice but to use VPN but better to use those paid and not the free one.
But if you are using it from restricted region then you are directly violating the terms of casino as they have mentioned those regions so it's until then when you are not caught because casino wouldn't allow players to gamble using VPN in that case.
It has been mentioned before here, but don’t use a VPN if your country is on the restricted list. Duelbits accepts the use of a VPN to bypass some of their casino games so you can always play your favorite slot but only use a premium vpn as free ones will cause issues.
If someone is from a restricted country using a VPN, they better be careful because Duelbits could ask or ask them to do KYC. And Duelbits may immediately block your account because you come from a restricted country or a country on its block list. Duelbits certainly wants to avoid getting in trouble by still allowing those from restricted countries to play in its casino. But it's best not to use a VPN if you can access Duelbits or another casino so that it doesn't cause problems. Or you can use a premium VPN to access casino sites.
