Gambling in the US is constantly changing and a handful of states now support legal online casino gaming. This is great news for blackjack fans, as they can now play at trusted online casinos in certain states. As one of the most popular casino games, blackjack is a perfect blend of pure luck, strategy, and skill. 

If you are in a state where online casinos are legal, our experts have written this guide to show you the best blackjack casinos available. Below is our complete online blackjack guide, including the best variants, bonuses, and bets. 

There are only a few places you'll find legal online blackjack:

• CT casino sites
• Delaware
• Top Michigan online casinos
• Best NJ online casinos
• Pennsylvania online casinos
• Best West Virginia casino sites

Once you’re physically present in that state, you can begin to assess the best sites. When you are on the hunt for the best online blackjack casinos, you want a site that does not compromise on anything. Blackjack players like you deserve the best all-around experience, which is why we go above and beyond to find the best blackjack gambling sites. Our team of experts provides a complete review of online casinos, covering the following essential factors:

Selection of games

We are reviewing specifically for blackjack players, so the casinos we highlight must have a broad selection of online blackjack games. Our team expects to see plenty of blackjack variants across virtual and live game lobbies.

Easy registration process

Blackjack players want to focus on the exciting parts of the online experience. The boring parts, such as registration, should be secure, efficient, and seamless. You can be up and running with a new account in minutes at the blackjack casinos we recommend. 

Best Blackjack sign-up bonuses

Casino bonuses are great fun and also give your bankroll a little extension. Yet, not all bonuses are worth playing for because some have harsh requirements. Our goal is to connect you with casino bonuses that cater to blackjack players with generous and accessible terms. 

Casino and Mobile Functionality

Compatibility is essential in this day and age, as gamblers like to play across a range of platforms and devices. The best online blackjack casino operators on this page provide a seamless user experience whether you are on mobile or desktop. 

Safety and Security

No other factor is as important as security, safety, and fairness. Each of the blackjack casinos we list has a license to operate legally in legal gambling markets in the US. Furthermore, we check that the site has a reputation for fair game outcomes and secure data protection. 

Bonuses are a fundamental part of the online casino experience. They are a way for casino sites to attract new customers and keep existing players happy. Because of this, the casino promo market is ultra-competitive, with plenty of the best casino bonuses available all the time. When you browse the blackjack casinos we select, you will typically find these common promotions:

Welcome Bonus

The most common and most lucrative casino bonus, the welcome bonus, is available to new customers when they register with an online casino. Right here on this page, you’ll find many promo codes that lead you to welcome bonuses. Most welcome packages are a deposit match and/or free spins. The match bonus will see the casino reward you by a percentage amount when you deposit for the first time. For example, a 100% match on deposits up to $100. On the other hand, free spins casinos give you a chance to play a popular slot game (or games) for free. 

Reload Bonus

A reload bonus works like a deposit match bonus. Yet, instead of being for new customers, it is available for existing players when they re-deposit at a casino. The offer may be slightly less than a welcome bonus. For example, a 50% match up to $50. Therefore, if you deposit $50, the casino will reward you with $25 in bonus funds when wagering requirements are met. 

No Deposit Bonus

All blackjack players love no deposit bonus codes because it is as close to free cash as you can get at a casino. Here, the casino will reward you with free funds without you needing to make a deposit. You can use these funds on select online games, such as slots and often blackjack. However, the wagering requirement will be higher than a standard deposit match bonus. 

Loyalty Reward Card Points

Online casinos often have loyalty schemes that reward customers. Usually, a loyalty program works on a point system where you accumulate points each time you wager real money on the site. The more points you gather, the more benefits you receive. Most schemes have levels where you reach increasingly valuable perks as you gain points. 

Cashback

Cashback is a bonus where the casino returns a percentage of the amount you wager during a specific time. Sounds great, and it is, but this is often limited to VIP players. These are high rollers who spend a lot of money at cashback casinos. If you high roll playing online blackjack, you will likely be invited to be a VIP and could eventually earn a cashback bonus. 

Refer a Friend

Open to all customers, a refer-a-friend bonus is a relatively straightforward way to pick up some bonus funds. All you need to do is link a friend to the casino. If that friend registers and deposits, you will be in line for a bonus reward. The bonus amount will be relatively small, such as $15. But hey, not bad if the casino is awesome and worth recommending to your friends. 

Blackjack is one of the most diverse games, with multiple variants each putting a unique twist on the standard game. Some variants, such as standard, multi-hand, and Spanish 21, are ideal for beginners. Alternatively, more complex variants such as Blackjack Surrender and Atlantic City will add side bets into gameplay. 

If you love the flexibility of picking different variants, you are in for a treat at the blackjack casinos we recommend. At our leading online casinos, you can play the following blackjack games:

Classic Blackjack

The traditional form of the game, standard blackjack, is what you will find at most online casinos. Here you will play on eight 52-card decks. An ideal variant for beginners or purists, classic blackjack is the simplest in terms of gameplay because it removes most side bets. RTP: 99.75%

Atlantic City Blackjack

Unlike most blackjack variants, the Atlantic City version will allow you to double on any hand. In standard games, you may only double on specific hand values. Atlantic City blackjack gives you more freedom to gamble when you want. RTP: 99.65%

Blackjack Surrender

Blackjack Surrender introduces the “Surrender” side bet as an option during game rounds. If you’re unfamiliar with surrender, it is an option that allows you to fold your hand before it meets the dealer’s hand. Doing so will enable you to recoup half your bet if your hand is poor. 

Super Fun 21

A fast-paced version for players who like rapid action and easy gameplay, Super Fun 21 can be played on one, two, or six decks. It has some unique rules, such as blackjacks (Ace and picture card) only paying out even money. RTP: 98.84%

Multihand Blackjack

If you are a polished player with experience, multihand is an excellent blackjack variant. Here you will be playing multiple hands at the same time. In all other aspects, the game is the same as standard blackjack, but with the added pressure and skill of playing multiple hands. RTP: 99.60%

Double Exposure Blackjack

Popular at many blackjack casinos, double exposure gives the dealer both their cards facing up. In other variants, the dealer cards are either both down or one down and one up. This is a significant change because it means the dealer in double exposure can make a more informed decision about the quality of their hand. RTP: 99.33%

European Blackjack

Online blackjack is already based on European blackjack, but modern standard variants are now slightly different from the classic European game. When playing European versions of blackjack, the player receives both cards face down, and the dealer does not get a second card until the player bets. RTP: 99.60%

Blackjack Switch

Created by Geoff Hall in 2009, Blackjack Switch is a modern variant best suited to experienced players. Here the player receives two hands instead of one and can switch the top two cards of both hands if they choose. RTP: 99.40%+

Spanish 21 Blackjack

Arguably the most unique version of blackjack, Spanish 21 removes all cards with the value of 10 (10s, Jacks, Queens, and Kings) from the playing decks. This makes it a more exciting and dramatic game because you need to hit more cards on each hand. RTP: 99.58%

Live Dealer Blackjack

If you want to get a taste of an authentic land-based casino from the comfort of your home, Live Blackjack online is the best option. Here you will play with other players against a human dealer streaming directly to your device from a remote studio. All popular Blackjack variants are available as a live casino option.

In the game of blackjack, you will compete against the dealer to achieve a score as close to or on 21 as possible. You win when you have the higher value hand and are within 21. To help you achieve this goal, you can choose to stand (stay with the hand value you have) or hit (take another card). If you go over 21 (bust) or the dealer has the better hand under 21, you lose. 

Blackjack is easy to play but has complexities that make it hard to master. A good start is to learn the terms of a game of blackjack, as well as the card values. That latter part is easy enough with the numbers 2 – 10 having their number value, Jacks, Queens, and Kings with the value of 10, and an Ace with the value of either 1 or 11. 

To really take control of your blackjack gameplay, the following terms will help you become a natural:

• Deal: When the dealer deals the cards that will make your hand. Blackjack starting hands have two cards. 
• Hit: When you ask the dealer for an additional card. You do this if your hand value is too low and you want to improve it. 
• Stand: A betting decision when you stick with the two cards in your hand. Take this option when your two cards make a strong hand.
• Split: If you have a card of equal value, you can split the hand into two separate hands. When you do this, you will need to re-bet the original wager amount on the new hand too. 
• Double Down: A side bet where you can choose to double the bet on your first hand. This should only happen under specific hand scenarios. 
• Insurance: If the dealer shows an ace on their visible card, you can choose to take the insurance bet, which guarantees a payout even if you lose. 
• Ante: The ante is a gambling term that represents the amount of money a player must commit as a minimum to take part in a game. 
• Dealer: Also known as the croupier, the dealer is the person who handles the cards and passes them to players. In blackjack, the dealer is also who you compete against. 
• Hole Card: A hold card is the one that is face down in the dealer’s hand.
• Up Card: The up card is the card that is visible, facing upwards in the dealer’s hand. 
• Shoe: At blackjack casinos, the shoe is the card dispenser that saves time in shuffling the cards. 
• Blackjack: This is the strongest hand in the game, consisting of an ace and a ten, jack, queen, or king (21 in total).
• Surrender: A side bet where you can choose to surrender a hand that looks poor and recoup 50% of your initial wager. 
• Bust: When you or the dealer has a hand that goes over the value of 21. 

As you have read on this page, there’s quite a bit of terminology in the game of blackjack. Here are some more terms to know, plus their abbreviations: 

• DOA: Double on Any (first two cards)
• D10/11: Double on 10 or 11
• DAS: Double After Split
• H17: Dealer must hit a soft 17
• S17: Stand on soft 17
• ESR: Early Surrender
• LSR: Late Surrender
• RSA: Resplit Aces

When we select blackjack casinos, our team of industry experts looks for operators that offer a wide selection of payment options for deposits and withdrawals. Flexibility is vital across a range of online casino payment methods, including:

Bank and wire Transfer

Traditional options involve depositing and withdrawing directly from/to your bank account. Withdrawals via bank transfer take longer than other methods, sometimes up to 5 days. 

ACH and e-check

Deposit and withdraw from your checking account with ACH. Cashing out winnings takes up to 11 days, usually faster, but making for a poor withdrawal option. 

Credit cards

Options like Visa and Mastercard are convenient for deposits and withdrawals. However, there are sometimes fees involved when using credit cards. 

e-wallet

Casinos that accept Skrill and other e-wallets like PayPal are some of the top choices because of speed. These e-wallets are quick, secure, and convenient, but sometimes casinos block e-wallets from bonuses, so be sure to check promo T&Cs. 

Prepaid cards

An ideal solution if you want tight control over your bankroll, prepaid cards like PayNearMe or Play+ allow you to top up when you want and how you want. You can top up your card at CVS, 7-Eleven and other convenient stores. However, sometimes prepaid cards are less convenient than other methods. 

Casino Cage

Many blackjack casinos operate under the gambling license of a land-based partner. So if you happen to visit a casino, you can go straight to the cashier and make your deposits and withdrawals in person. 

You can find online games from leading software providers at the top blackjack casinos we recommend. While legal US casinos typically have fewer options than European iGaming sites, you can still find a broad selection of games. 

Swedish developer NetEnt is known for high-quality casino games with superior visuals. Notable blackjack games from NetEnt include Blackjack Classic and Single Deck Professional Series. 

IGT is known for its market-leading land-based slots and for being one of the best slots sites, but the US brand also has stand-out blackjack games, such as Blackjack Player’s Suite.

The biggest developer of live dealer casino games, Evolution has more Live Blackjack options than any provider, with notable titles including Infinite Blackjack and Free Bet Blackjack.

Formerly known as Scientific Games, Light & Wonder is known for its commitment to virtual games, with excellent blackjack variants like Blackjack Switch and Live Blackjack.

We won’t deny that playing blackjack for real money at blackjack casinos provides the ultimate excitement. There’s nothing truly like putting your hard-earned cash on the line with the hopes of walking away with a profit. However, many iGaming providers offer their online games in demo mode – in this case, as free blackjack – which is beneficial to get to know the game without risking money. 

Playing free blackjack comes with many unique advantages, but also a few cons, including the following:

If you love playing blackjack via computer but want to take the fun with you on the move, mobile blackjack casinos are an excellent option. While a desktop gives you more screen space, mobile blackjack is convenient, allowing you to place bets and play blackjack whenever and wherever you wish, as long as you have a stable internet connection. 

All modern blackjack casinos are available via a mobile browser. Websites have been built with HTML5 technology, allowing them to run smoothly on mobile hardware. They are responsive and optimized for smartphones and tablets, transitioning seamlessly from desktops to mobile devices.

You may prefer to download dedicated US online casino apps instead. Many operators offer an app for iOS and Android. While you will need to have the latest software on your device, an app is useful because it sends notifications, has better connectivity, and is easier on battery life. 

To have the best experience at blackjack casinos, you need to be confident and know the game. Below are our top tips to help you take your blackjack to the next level:

• Avoid the insurance bet: It simply does not provide good enough odds to be worth losing 50% of your wager for.
• Use basic blackjack strategy charts: Betting strategies cannot guarantee wins, but a basic blackjack strategy chart will help you know when to hit, stand, double down, or split under specific scenarios.
• Pick high payout games: Choose the games with the highest payout rates to help extend your bankroll and potentially win more money.
• Gamble responsibly: Remember, always gamble within your means and set a budget of disposable income you can afford to lose.

Card counting is when a player keeps track of high and low-value cards as they are dealt. In theory, you can gain an advantage by knowing which cards have already been used. However, card counting is impossible when playing a virtual blackjack game. That’s because these games use random number generators, so all cards and outcomes come down to random chance. Sure, it is possible to card count in live casino blackjack games, although the casino operator is likely to ban you if they find out.
