And best of all, you can do it from anywhere!

In today's information age with the global reach of the World Wide Web, you can legally play blackjack online from your smartphone or favorite PC, any time day or night.

Is It Legal To Play Online Blackjack In The US?

Yes, there is nothing illegal about playing online blackjack for real money, even if you live in the USA. Check out our USA gambling laws page to learn more about the exact laws that apply to online casino gambling.

Is It Legal To Play Blackjack Online?

Yes, for most US residents aged 18 and up, online blackjack is legal and safe, provided you use one of the casino sites listed here. There are no US federal laws that prevent individual gamblers from signing up and playing with offshore operators for real money, and millions of Americans use these services every day.

The state of Washington has laws on its books banning all forms of online gambling, but these are unenforced, and we’ve never uncovered even a single instance of any 18+ blackjack player getting fined or arrested for online gaming in WA. Still, we advise abiding by all local laws and proceeding only at your own risk.

Note: No top-rated online BJ casino currently accepts NJ residents. While it isn’t against the law for New Jersey gamblers to use offshore sites, they’ll have to do so outside of state borders for the time being.

Safest Ways To Deposit Funds Into Your Blackjack Accounts

The best banking option for depositing into your casino account is going to depend on several factors. However, the fastest deposits can be made with credit, debit, Bitcoin (BTC), or another supported cryptocurrency. We prefer BTC and crypto, because these are the most secure and reliable methods of deposit, have no added fees, come with the biggest blackjack bonuses, and have quantum-hacking-resistant encryption.

Other common banking methods include wire transfers, money orders, person-to-person services (like MoneyGram), cashier’s checks, and so on. These all cost more to use and process much slower, so they’re not recommended for players who want to hit the digital blackjack tables ASAP. You can also see our guide to Google Pay online gambling sites and see what sites offer popular P2P services like Paypal, vouchers, and more.

For withdrawals, Bitcoin and crypto are again king, and they're the only methods that let you get your payouts the same day you request them. They're also the only blackjack payout options that don't have large processing fees associated with them. For sites that take other cryptocurrencies in addition to Bitcoin (Litecoin, Ethereum, Ripple, Bitcoin Cash, etc.), you can typically get the same BTC benefits.

2024's Best Real Money Blackjack Apps

Mobile casino applications are the real jackpot in the offshore casino industry, as they let you play from anywhere, any time. That said, you won’t find any iPhone blackjack apps or Android blackjack apps for real money in the App Store or on Google Play, due to those stores’ corporate policies.

But that doesn’t matter, because the best BJ operators have all put together web app experiences for their players. You can access these by simply visiting your casino site of choice via your mobile device’s web browser, and the blackjack tables will automatically conform to your device’s parameters. You’ll get intuitive tap and swipe style controls, too, and there’s no need to worry about downloads and updates. It’s the best of both worlds – it’s literally blackjack!

Be sure to learn more about how mobile gambling apps work if you have any questions.

Live Dealer Blackjack Options

If you’re looking for live dealer blackjack online, all the top sites we recommend offer this feature. While you can enjoy RNG (random number generation) games of 21 in these casinos, you can also join live tables where real dealers are flipping the cards.

This is a fun way to simulate a brick-and-mortar experience in the virtual realm, and it adds a bit of human touch to the online game. You can even choose which dealers you like best, and spectating is also possible, so you can watch other players and learn their strategies before spending your own money.

How To Play Blackjack

Blackjack is one of the easiest casino games to learn, and online 21 has the same rules as those you’ll find at any retail casino in the US. All you need to do is be the closest to 21 without going over. The cards are ranked by face value, with face cards each being worth 10 points and the Ace being either worth one point or 11 points.

The dealer will deal each player at the table – including themselves – one card, face up. Then, each player gets another card, also face up. However, the dealer’s second card is dealt face down.

You can then elect to be “hit” and receive a third (or fourth, or fifth) card if you think it will bring your total closer to 21. If you go over 21, this is called a “bust.” In blackjack, each player plays only against the dealer/house.

Blackjack Rules

The rules of 21 are simple, and the basics are outlined above. While some blackjack rules will vary based on the casino or game type you’re playing, most have the following dictates:

  • Each player gets two cards to start, face up.
  • The dealer gets two cards, with second card face down.
  • Players do not compete against each other. They only compete against the dealer. If several players are at a single table at the same time, you can view this as being several independent games being played simultaneously against the house.
  • The goal is to build a hand that is closest to 21 without going over.
  • Numbered cards are worth face value.
  • Picture cards (J, Q, K) are worth 10 points. Jokers are not used.
  • Aces are worth one or 11 points, depending on the player’s needs.
  • If you get a 10 or a face card and an Ace, this is called a “natural” blackjack and is a winner.
  • If you are dealt two of the same cards by rank, you can elect to split your hand and play two hands, receiving a second card for each. This requires you to double your bet, however, and can be a risky move.
  • If both the player and the dealer bust, the player loses.
  • If both the player and the dealer have blackjack, the bet is a push and no money changes hands.
  • A natural blackjack (i.e. scoring 21 in two cards) beats any hand of 21 that utilizes three or more cards.
  • The dealer typically must hit on 16 or less and stand on 17 or more.

The HIstory Of Blackjack In America

Blackjack – originally known as “Twenty-One” – has unknown global origins, with the first recorded references coming from the writings of Miguel de Cervantes, author of Don Quixote, who first mentioned it in approximately 1600.

When the game came over the sea to America, casinos had a jackpot promotion where a natural 21 consisting of a black Jack card (Clubs or Spades) and an Ace of Spades paid out at 10-1 (or +1000). The hand was dubbed a “blackjack,” and the term caught on, becoming the moniker for the game today. Now, of course, a “blackjack” is any hand that adds up to 21 in only two cards (that is, an Ace plus a 10, J, Q, or K).

Blackjack has been famous ever since, thanks to its simplicity, straightforward rules, and sedate pace of play. Now, with online 21, the popularity of this centuries-old game is greater than ever, and you can get in on the action at any reputable offshore legal betting site.
