♠️ What is online blackjack?
Blackjack is a card game, and the goal is to beat the dealer. To beat the dealer, you must get a card total closer to 21, without going over that number.
Here is what each card is valued as:
- Cards 2-10 count as face value.
- Jacks, Queens, and Kings (face cards) count as 10.
- An Ace can count as a 1 or an 11, depending on which number helps the hand.

Which states allow legal online blackjack?
While it is legal at the federal level, casino gaming is regulated by each individual state. There are certain states that allow traditional online casinos, whereas some states offer what are known as sweepstakes casinos. This is a casino where you essentially play for free but can still redeem winnings. However, not all sweepstakes casinos offer blackjack.
If you live in a state that offers real money casinos rather than sweeps, we have you covered.
- Michigan: Blackjack fans in MI have their pick of the best Michigan online casinos.
- New Jersey: NJ online casinos bring the glamour of Atlantic City to you.
- Pennsylvania: Our list of all PA online casinos has something for every type of player.
- West Virginia: Playing at WV online casinos gives you plenty of choices.
- Connecticut: Live in the Nutmeg State? You'll find a small selection of CT online casinos.
Rhode Island and Delaware also allow casinos to operate online, but these states are currently single-operator monopolies.
📝 How to play blackjack online
Here is a step-by-step look at how to play blackjack online:
-
Join a table
You will first want to identify what the minimum and maximum bets are at a table. Be sure to play within your limits and be mindful of your blackjack budget.
You will then want to find an open seat at a table. Most blackjack tables have five or seven seats.
Because you're playing online, you don't have to worry about where you sit at the table or the best time of day to play blackjack.
-
Decide whether to hit or stand
A key decision when playing blackjack is to “hit” or “stand.”
“Hit” means that you want another card from the dealer so that your hand’s total will improve.
To “stand” means that you are satisfied with your current hand and believe that you have the right total to beat the dealer.
-
Choose to hit
When your total is low, you will want to hit. If your hand is 11 or less, it’s a no-brainer to hit.
You will also want to be aware of the dealer’s upcard. Per basic strategy, if the dealer’s upcard is between a 7 and an Ace, and your total is 12-16, you should probably hit.
Novice blackjack players should know that you can keep hitting until you “bust” (i.e., go over 21).
-
Choose to stand
If your hand totals 17 or higher, you will typically want to stand. The odds of busting are strong if you hit on a number higher than 17.
-
Your hand value
The dealer will initially give you two cards, face up.
The dealer will have one card face down and one face up. Remember, your goal is to get closer to 21 than the dealer.
You must weigh your own hand’s total against the probability that the dealer will have a strong hand to determine your hand’s value.
-
Dealer reveals their cards
After all the players at the table are done playing their hand, the dealer will flip their hole card (the card that is initially face down). The dealer will then play their own hand.
-
See who is closer to 21
After the dealer has played their own hand, it’s time to see who is closest to 21. If you are closer to 21 than the dealer, you win. In the event of a tie, it is a “push,” and you will get your original bet back.
Blackjack knowledge is power
Playing blackjack isn't all about strategy. It helps, sure, but in the end, the goal of playing any casino game is to have fun. When the fun disappears from your blackjack game, it's time to take a step back and ask yourself, "What am I getting out of this?" If the answer is, "Nothing but an empty wallet," take a breather. Responsible gambling means playing blackjack and having a blast, not betting it all on one hand.
🆓 Playing online blackjack vs. free games
There are two options for playing blackjack online. You can either play real money online blackjack, or free online blackjack.
Playing free online blackjack is a great way to warm up for the real deal. Many sites won’t even ask you for sign-up information, giving you quick and easy access to play this exciting game.
Of course, the downside to playing these free blackjack games is that you can’t win money. Only real money online blackjack allows you to wager and win in the true sense.

💡 Online blackjack tips
Gamblers crave as much information as possible prior to placing a bet. Knowledge is power at the blackjack table, and we’ll give you some key pointers here:
- Understand house edge: The house edge is the mathematical advantage that a casino has over the player. What makes blackjack so popular is that the house edge is typically around just 1%.
- Manage your bankroll: If you are playing for real money at an online blackjack site, you will certainly want to set a bankroll beforehand. This is the amount of money you plan to use for gambling in advance.
How to track casino spending without killing the fun
Being responsible doesn't have to be a buzzkill. Check out our guide on how to track casino spending without killing all the fun.
- Try betting systems: An easy way to manage your bankroll is to use specific betting systems. Popular blackjack betting systems include the Martingale System, the Paroli System, and flat betting. More on systems in a bit.
- Always split Aces and 8s: Splitting in blackjack is when you have a pair, and you decide to separate them into two individual hands. One of the most basic rules of basic strategy is to split aces and eights. Splitting gives you two chances to hit 21.
- Be wary of insurance: Blackjack insurance is a side bet on whether the dealer has blackjack. It is independent of your original bet. The risk here is that insurance bets lose more than they win. The house edge on an insurance bet is around 7.5%, compared to around 1% on a normal game.
Card counting online?
Unfortunately, you amateur card counters are out of luck if you hope to bring down the house virtually. Online casinos use a virtual shoe. It is impossible to count cards when online blackjack uses an RNG (Random Number Generator) to deal the cards. So, you math whizzes will have to get up off the couch, get dressed, and head into an in-person casino if you hope to count your way to glory.
♦️ Popular blackjack variants
Another great thing about blackjack is that there is a wide variety of versions. In addition to the classic blackjack we’ve already discussed, there are wildly fun versions like Blackjack Surrender and Double Exposure Blackjack available to play on real money casino apps and sites. Here are some of the most popular blackjack variants:
In classic blackjack, you want to create a card total that equals 21, or at least comes close to 21 without going over it. You want your hand to beat the dealer’s hand.
The biggest difference between classic American blackjack and European blackjack involves the dealer card. In European blackjack, the dealer only gets one card initially. The second card is dealt after the player is done.
Multihand blackjack is exactly what it sounds like: you can play multiple hands against the dealer. Multihand blackjack will use anywhere from 4-8 decks of cards.
Single deck blackjack uses one deck, made up of the standard 52 cards. Gamblers love single deck blackjack because it's easier to count cards, and it has a lower house edge.
You can play up to three hands at once in duel blackjack. When the game begins, you must place an ante bet. You have the option of folding after you are dealt two cards (one face-up and one face-down) and see the communal cards.
Atlantic City blackjack is played with eight decks of cards, and the dealer must stand on 17. You are allowed to surrender your hand.
This is another straightforward name of a blackjack variant. Blackjack surrender is appealing because you have the option to surrender (fold) your hand after the initial deal and after the dealer has peeked for blackjack. Of course, if you do surrender, you only get half of your stake back
Blackjack switch requires a sharp gambling mind. Each player plays two hands at the same time. Where the fun lies is that you are allowed to switch the second card of each hand in order to create stronger combinations.
In this type of blackjack, both of the dealer’s cards will be exposed; hence, the name. The dealer will hit or stand on soft 17, and the dealer wins all ties.
5️⃣ Top 5 blackjack variants for odds
“How low can you go?” is often associated with the game of limbo, but it also applies to blackjack variants. As we mentioned earlier, a major reason blackjack is so popular is its incredibly low house edge.
Here is a table with the top five blackjack variants for odds:
| ♦️ Game | ⚖️ House Edge |
|---|---|
|
1️⃣ Single deck blackjack |
0.13% — uses just one deck, easy to count cards. |
| 2️⃣ Blackjack switch |
0.17% — ability to switch the second cards between hands allows for favorable outcomes for the player. |
| 3️⃣ Atlantic City blackjack |
0.35% — can split pairs up to three times each. |
| 4️⃣ European blackjack |
0.39% — dealer does not get to peak because there is no hole card. |
| 5️⃣ Multihand |
0.63% — having more hands gives you more chances at winning. |
🤓 Online blackjack strategy
You will hear a lot about basic strategy when discussing the game of blackjack. You might also be asking if basic blackjack strategy works online?
Simple put, blackjack basic strategy is a mathematical set of rules that determines when you hit, stand, double down, or split. Let’s look at the fundamentals of blackjack strategy:
- Pair splitting: If you are dealt two cards of the same number in blackjack, you can elect to split them. For instance, if you were dealt a pair of 8s, you could choose (and should choose) to split them. This is because with two 8s you would have a weak total of 16.
- Soft totals: A soft total is a hand that uses an Ace card as an 11. If you had an Ace and a 3, you would have a “soft 14.” The Ace card offers flexibility, as it can be used as a 1 or an 11.
- Hard totals: Unlike a soft total, a hard total does not have flexibility with an Ace. Let's say you had an Ace, a 6, and a 10. You would have a “hard 17.” The Ace is forced to be a 1 in this scenario, because if it were used as an 11, you would bust. You can also have a hard total without an Ace. For example, if you had a 10 and an 8, it would be a "hard 18.”
- Late surrender: A late surrender by the player can occur after the dealer has checked their cards and does not have blackjack. The player can fold in this scenario and receive half of their bet back.
💸 Blackjack betting systems
Savvy gamblers will go to the blackjack table with a plan. There are several different strategies, or systems, you can use. While none of these guarantee positive results (it’s called gambling for a reason), they are tried-and-true methods that have been used by veteran blackjack players for decades.
The Martingale system goes on the premise that you “must win eventually.” With this strategy, you double your bet after every loss. After a win, you revert back to your original bet size. It is an aggressive and risky strategy.
The D’Alembert system is similar to the Martingale system in that you increase your bet after a loss. The difference is that after a win in the D’Alembert system, you decrease your original bet size.
The Fibonacci system is a betting strategy based on the Fibonacci sequence. The Fibonacci sequence is a mathematical pattern in which every new number equals the sum of the previous two numbers. The sequence goes as follows: 1-1-2-3-5-8-13-21-34-55-89, etc. Blackjack players will use this sequence to decide how much to bet after each loss. When you win, you go back two steps and reduce your bet size to that number.
You follow a sequence of bets in the 1-3-2-6 system: 1 unit, 3 units, 2 units, and finally, 6 units.
Here is an example:
- Begin with a $10 bet
- If you win, you increase the bet to $30
- If you win again, you bet $20
- If you win a third time, you increase the bet to $60
If you lose at any point, you restart the sequence.
In the parlay betting system, the more you win, the more you bet. It is a pretty safe system, because if you lose, you simply continue to bet your initial minimum wager.
As an example of the parlay betting system, if you make a $2 bet and win, you would then have $4. You then bet that $4. If that $4 wins you would then have $8, and you would then bet that $8, and so on.
If you’re something of a cautious gambler, Oscar’s Grind is right for you. It’s also great if you want to stay at the blackjack table for a long period of time. Basically, when you win, you up the stake by one unit. If you lose, there is no change in the amount of your original bet. When you get a net profit on one unit, you restart the sequence.
📖 Blackjack glossary
Blackjack is a pretty easy game to learn, but you will want to know all of the terminology before playing. Here is a handy blackjack glossary with all of the key words and phrases you need to know.
Ace: An Ace card in blackjack can be either a 1 or an 11. If the ace card puts your total over 21, it will be used as a 1.
Blackjack: Blackjack is when you hit 21 on the nose. That is the ultimate goal of the game. If both you and the dealer get blackjack, then it is a push, and the player gets their original bet back.
Burn card: At the start of each round, the dealer will typically discard the top card from the deck/shoe. This card is called the burn card. This is done to prevent cheating from players. Cheating players may try to mark the back of a card so they know what is coming next.
Bust: Your hand “busts” in blackjack when it goes over the total of 21. If a player goes over 21 points, they bust and automatically lose.
Face cards: Face cards are the King, Queen, and Jack of any suit. In blackjack, these cards are worth 10 points.
Double down: Double down means to double your original wager. You are allowed to double down after you receive your first two cards. You then receive one more card, and you must stand with it.
Hard hand: A hard hand is a hand without an Ace, or a hand where the Ace has to be counted as 1 to avoid a bust.
Heads up: Heads up is when you play the dealer one-on-one. In this format, there are no other players at the table.
Hit: To hit in blackjack means to ask the dealer for another card to add to your hand. You can hit as many times as you want, until you choose to stand.
Hole card: A hole card is a face-down card that the dealer gets. The dealer receives two cards, a hole card and a face-up card (upcard). The dealer peeks at his hole card to see if he has natural blackjack.
House edge: The house edge is the amount of money the casino keeps over time. One of the main reasons blackjack is so popular is that it has a low house edge, often around just 0.5%.
Insurance: Insurance in blackjack is when you make a side bet that the dealer has blackjack. You are allowed to do this if the dealer’s upcard is an Ace.
Natural: A natural is when your first two cards add up to 21. In this scenario, the player wins immediately, unless the dealer also has blackjack.
Push: A push is when the player and the dealer both have a hand with the same total. When this occurs, you don’t win or lose. Your original wager is simply returned to you.
Stand: When you stand in blackjack, you no longer want any more cards. You stand when you are satisfied with your hand. It is the opposite of hitting.
Soft hand: A soft hand is when you can count an Ace as a 1 or 11. For example, if you have an Ace and a 7, you would have a “soft 18.”
Surrender: To surrender is to basically fold your hand early. Half of your bet is returned in this scenario, and you sit out the round.
Up card: The upcard is the face-up card that the dealer displays at the start of each hand. This card helps you choose what you want to do with your own hand.
