There is no one definitive answer to this question as the legality of online blackjack can vary from state to state. In general, however, it is generally considered legal to play blackjack online as long as you are playing with real money and following the applicable rules and regulations of your respective jurisdiction.
There are a few caveats, however. First, most online casinos will require you to verify your identity before allowing you to play. Second, some states have lAWS that specifically prohibit gambling by minors, so it is important to be aware of these lAWS if you are underage and plan on playing online blackjack.
Finally, some jurisdictions have lAWS that make it illegal to advertise or promote online blackjack in any way. If you violate these lAWS, you could find yourself subject to criminal penalties.
Overall, though, playing online blackjack with real money is generally considered legal and safe as long as you are following the appropriate rules and regulations of your respective jurisdiction.
