Im from Philippines, There might be some issue for user that connecting using my country IP. Anyway this good since this casino is playable by US citizens while most of the casino here is not allowed due to there license limitation. Im on what kind of license do you have for allowing US citizen to play and at the same time globally?
I personally use VPN France. There were no problems with access to the site and games.
You need to read their terms of service, they're not allow US citizen and US embargoed countries to gamble on their site.
Excluded Territory means the State of Washington in the United States and any outlying territories, and the province of Quebec in Canada, and any U.S. embargoed countries (currently Cuba, Iran, Myanmar (Burma), North Korea, Sudan and Syria), any other jurisdictions which, under the laws applicable to you, are legally precluded from playing the Games offered on the Platform, and any other jurisdiction Luckybird excludes, in its sole discretion, from time to time.
Also you're not allowed to access the site using VPN, they're don't allow it. That's nothing new anymore in licensed casino and it's high chance you will get asked to submit KYC. I don't know where you live, but if you're from the countries that I listed below, you will face a problem.
