Yes, playing blackjack online is legal for players in the United States. If you are concerned about the UIGEA bill that was signed into law back in 2006, don't be. That law provides regulations for online gambling site operators and focuses on how gambling-related transactions are processed. It really doesn't have any bearing on players. Some states do allow state-regulated online blackjack, but not many.  Each of the USA friendly sites featured in our guide are based outside of the U.S.A., but are legitimate and legal gambling sites operating legally within the industry, with official licensing and certifications, all verified by our team of professionals.
