How to Play Online Blackjack for Real Money

Online blackjack is one of the easiest casino games to learn and play. The set-up is simple and you can enjoy low-stakes gambling online. Here’s how a game of classic blackjack works.

Selecting a Game

First, select a blackjack table from the online casino lobby. Often you will have a choice of Demo Play and Real Money tables. Make sure you have enough cash in your account before playing blackjack online for real money.

The Deal

Open the blackjack table and select your stakes. Good US casinos will clearly display the minimum and maximum bets available, plus the maximum payout.

Click on the circular Ante or Bet spot on the screen. Then, click the Deal button. You will receive two cards face up, while the dealer receives one card face down and an up card.

Hit or Stand

You now have two options: Hit or Stand. If you hit, you receive another card to your hand total. Keep selecting Hit until you want to Stand and receive no further cards.

It’s now the dealer’s turn. The computer draws cards until they bust or reach 21. In classic blackjack, the dealer must stand on hard 17 – that is, a 17 containing no ace.

Insurance

You can also take an insurance option when you play blackjack online. Insurance is offered if the dealer shows an ace up-card. By taking insurance, you place a second bet on the chance that the dealer has hit a blackjack. If they do, you win 2/1.

Double Down and Split

You also have an option to double down or split a pair. If you split a pair, you create two unique hands and place a second bet equal to your initial bet. You continue to hit and receive cards on both hands. This gives you double the chance of beating the dealer.

A double down is usually allowed on totals of 9, 10 or 11. You place a second bet equal to your first bet and receive one extra card. That is the end of your hand, and it’s the dealer’s turn to play.

Payouts

The aim of blackjack is to beat the dealer’s hand without going over 21. If you are dealt a blackjack (an ace and a picture card for a total of 21) you immediately receive 3/2 on your money. In some blackjack variants, the hand is tied if both you and the dealer have a blackjack.

Blackjack Card Values

When you play blackjack online, you add card values together to make a total worth 21 or less. Cards are valued as follows. Face cards are worth their pip value, while 10s and picture cards are worth 10. The ace counts as 1 or 11, depending on what total you are trying to achieve:

  • Two: 2
  • Three: 3
  • Four: 4
  • Five: 5
  • Six: 6
  • Seven: 7
  • Eight: 8
  • Nine: 9
  • Ten: 10
  • Jack: 10
  • Queen: 10
  • King: 10
  • Ace: 1 or 11

Common Bonuses to Claim and Maximize

The best online blackjack sites offer a range of bonuses for new and existing players. Casino bonuses vary from casino to casino, so check out our in-depth reviews to find the best deals and always read the term and conditions carefully as they explain playthrough requirements.

Welcome Bonus: As a new signup, you can claim free cash as part of a welcome bonus. Open your account, make your first deposit, and receive bonus funds in your account.

You will have a time limit within which to clear your bonus cash. Only a portion of your blackjack play – possibly 10-20% – will contribute toward the bonus total. But if you meet the wagering requirements you will be able to withdraw your winnings.

Reload Bonus: A reload bonus is reserved for regular players who have already claimed a welcome bonus. Your deposit might be matched 25-50% by the casino. You now have a few days to clear the bonus funds before you can withdraw them.

Cashback: Some US online casinos offer cashback on your losing blackjack bets. All losing wagers over a set period will be refunded straight to your account.

Blackjack Software Providers

There are a handful of regulated software providers in the US that provide blackjack online. You will find one or more of these developers at the best online casinos in your home state.

Shuffle Master’s Super Fun 21 Extreme is legal in some US states and features exciting side bets that can pay up to 250x your stake.

Blackjack Online Deposit & Payment Methods

Are you ready to play blackjack online for real money? You will need to open a legal account and make a deposit before you play.

Luckily, making a deposit at US casinos is really easy. All you need is a valid bank card like Visa or MasterCard, or transfer cash direct from your checking account.

Here are some of the best ways to deposit at top online casinos:

Visa/MasterCard: Acceptance rates in the US are still low as some financial institutions still block credit card transactions even for legal gambling, but Visa and MasterCard offer a safe and quick way to deposit using your debit or credit card. Note there are also fees associated with using the card.

Wire Transfer: Leave the card in your wallet and make a transfer direct from your bank account. All you need is your routing number and account number to complete the payment.

e-wallet: You can use an e-wallet like PayPal or Skrill to store funds from multiple cards and accounts. Transfer funds into your blackjack account and enjoy instant play.

Prepaid Card: A prepaid card like Play+ is ideal if you want to avoid using a debit or credit card. Load funds onto your prepaid card with a credit card or bank account and make a transfer in seconds. Transactions are fee-free, and acceptance rates at casinos are high. You can also withdraw back on to the card from the casino and access the money at ATMs.

Casino Cage: A cage deposit is the perfect solution if you live near a brick-and-mortar casino with an online casino partner. Visit the casino affiliated with your online casino in person and make an instant deposit with cash or card.

PayNearMe: With PayNearMe, you can use cash to make an online blackjack deposit at your nearest 7-Eleven or CVS. Just pay the local fee and make a cash transfer in 30 minutes to your casino account.

Can I Play Blackjack Online for Free?

Free online blackjack is the perfect way to learn the rules if you aren’t comfortable with playing for real cash.

Most legal US casinos online supply demo play versions of classic blackjack. You don’t always have to register an account, either. Just visit the site and load up a free-play game in your browser.

Playing free games is great if you’re completely new to blackjack online. Get a feel for the flow of the game and how moves like double down and split work. You can also hunt around for the best blackjack variant with the lowest house edge.

TopUSCasinos is the leading source for real money blackjack online. While we don’t offer free-play blackjack on our site, we rate and review dozens of legal US casinos that offer demo play games.

You can also try social casinos such as Winstar and Chumba, which are legal across the US. Social casinos allow you to play games for free with virtual coins, and some offer sweepstakes where you can win real cash or prizes.

Mobile Apps for Online Blackjack

You can now play blackjack online through your mobile device. Whether you’re on Android or iOS, the most trusted US online casinos offer an app for you.

Blackjack casinos tend to offer one of two ways to play: download or no-download. You may find a dedicated legal app in the App Store or Google Play, but a lot of the time you will be downloading an app direct from the casino homepage. You can also enjoy instant-play blackjack games through your browser.

Here’s what you will need for mobile blackjack. First, ensure your device can run a game without any glitches. Commonly, you will need Android 4.4 or better, or iOS6.0+ if you use an iPhone or iPad.

If you are playing no-download games on your mobile, make sure your browser is up to date. Install the latest Google Chrome or Safari apps for your device before you get started.

You can play online blackjack for money on your smartphone, but the experience is a little different on mobile. The game screen is converted to work on your device, and bets are made via the touch screen. You may also find a limited range of variants on a mobile casino compared to the desktop version.

Blackjack Strategies to Help You Win

Playing blackjack for real money is a real blast. But you can improve your chances by using some simple strategy. Here are our top 3 tips for better blackjack play.

Avoid the Insurance Bet: The insurance bet is probably the biggest sucker bet in blackjack. The 2/1 payout doesn’t come close to covering the true odds of the dealer hitting his blackjack. That’s why it’s best to avoid insurance and continue the hand as normal.

Print Off a Cheat Sheet: Optimal blackjack strategy can help lower your house edge to around 0.4-0.5%. To help you make the right moves, print off a cheat sheet. This will show you when it’s best to hit, stand, double down and split.

Avoid the Worst-Paying Blackjack Variants: Top online casinos in the US offer a range of great blackjack variations. Always avoid games with poor payouts on a blackjack, such as Super Fun 21 with its 6/5 blackjack payout.

Is Counting Cards Illegal When Playing Blackjack Online?

Card counting has been a tool for professional blackjack gamblers since the 1960s. The method involves assigning a negative, positive or zero value to different cards.

Low cards are usually assigned +1, while high cards like J, Q and K are assigned a -1 value. The higher the count, the better it is for the player as there are more 10-value cards to come out of the shoe.

Card counting isn’t strictly illegal in the US, but it is frowned upon. Known card counters may have enforced betting limits or be excluded from tables altogether.

Over the years, casinos have introduced methods to deter counters. These include shuffling the decks after every hand. For online blackjack, the regular shuffles make it impossible to count cards.

Blackjack Variants to Play at Online Casinos

Online blackjack casinos in the US now offer a wide range of variations. Try out one for free today.

Classic Blackjack

Classic Blackjack is the most familiar form of the game. A blackjack pays 3/2, insurance pays 2/1, and the game is played with 6-8 decks.

Live Casino Blackjack

Live blackjack lets you take on a human dealer on your computer. The action is streamed via webcam, and special cards are used by the dealer which are scanned and displayed on your monitor. You can even talk to the croupier via the chatbox.

Atlantic City Blackjack

Popular in New Jersey, Atlantic City Blackjack is also a hit online. Players can double down on any hand, and you can also double after a split.

Blackjack Surrender

Blackjack Surrender gives you the option to let your hand go if the dealer shows a possible blackjack. You will receive half your original stake back if you decide to surrender the hand.

Super Fun 21

Super Fun 21 is an intriguing variety of blackjack found at some US casinos. You win a special payout if you have six cards totaling 20 or more. A blackjack pays 5/2 to 6/5, or 2/1 for a 5-card or 6-card blackjack.

Super Fun 21 also features the Diamond Bonus side bet. You can win 250/1 to 300/1 if you make a blackjack made of two diamonds.

Multihand Blackjack

Why play one hand when you can play up to five at once? Multihand Blackjack gives you control over 1-5 hands, all at the same time.

Double Exposure Blackjack

In Double Exposure, you get to see both the dealer’s cards. However, a blackjack only pays 1/1 (not 3/2), and there is no Insurance option. The dealer also wins every push.
