I just download a vpn app and run it? Then i can use site from regular browser?
Yes type in google best VPN providers and do a little research to find which one you prefer at the best rates. There are many out there, obviously make sure you don't use a US or maybe UK IP when you choose one ha.
You will be good to go and yes from regular browser should be good. I am not 100% but clear cookies if it is a casino you have already tried as I really don't know if they can get ya that way so clearing them will avoid that just in case they can which I doubt but better safe than sorry,
