Roxy Palace is regulated by Malta and powered by Mircrogaming casino games. Both Malta and Mircrogaming do not accept citizens from the United States of America.
I sent an email to the Roxy Palace support to get a clear explanation. Here is their answer :
Unfortunately we are unable to accept players from your country due to various laws in your region governing online gambling.
If you attempt to play from a different country but you live in the USA you will not be able to use your cards, as they will be coming from the USA and if you are requested documents you would need to provide a proof of residence from the country that you are playing from.
Therefore I wouldn't advise you to play from any other country if you are a US resident.
We hope that if/when your country legislates online gambling, you will not hesitate to open an account with us
As part of the US gambling law, Roxy Palace preferred to step back from the US Markets. However, some online casinos still continue to accept US citizens. Check our top 3 US Casinos.
Technically, you could play to Roxy Palace if you signed up from abroad. For instance if you are in vacation in South Africa or in Cancun, you could play to Roxy Palace while you drink your Bloody Mary. However, you should not use a US address and an american credit card (from HSBC for instance).
This is the same problem as "signing-up from abroad". You could use a VPN to play to Roxy Palace, but you would need to have a real address outside of the US (with utility bill at your name for instance). If you have an uncle abroad, for instance in the New Zealand, it could work. Otherwise, in case you win a $4,000,000 jackpot, Roxy Palace could block your funds..
We know that Bovada is currently accepting US citizens. It is powered by Top Game software and offers a nice welcome bonus.
