We only ever recommend casinos that are licensed and regulated by respected gambling authorities, so you can be sure that you’re playing on a fair and secure platform.

Popular Types of Online Blackjack Games

Blackjack as a casino game has evolved significantly since it was first created in the 1700s. Moving the game online has allowed developers to create a variety of different blackjack variants, each with their own set of unique gameplay features.

Picking from so many options can be daunting for some players, so we’ve highlighted the most popular online blackjack variants available at our recommended casinos.

Multi-Hand Blackjack – As the name suggests, this type of online Blackjack allows you to play multiple hands simultaneously. This is great for advanced Blackjack players who want to play more hands per hour.
Surrender – Blackjack Surrender almost identical to traditional blackjack games with one rule change; players have the opportunity to receive half of their bet back once they have been dealt their hand. This is great for advanced players who want to apply proper risk management strategies.
Switch – Blackjack Switch is an exciting version of online Blackjack where you play two hands at a time. After you’ve received your cards, you have the opportunity to switch the second cards between hands. This greatly increases your odds of winning, so in this game, the hand is a push if the dealer makes 22.
Insurance – In this version of the game, you can take out a insurance when the dealer’s up-card is an ace. By doing so, you are protected against a dealer’s Blackjack, and receive a 2:1 payout if they have one.
Vegas Strip Blackjack – Vegas Strip Blackjack rules, commonly referred to as ‘’Standard US Blackjack’’ rules include a surrender and insurance option, 3:2 payouts on blackjacks, and a rule which dictates that the dealer must stand on soft 17s.
Atlantic City Blackjack – This version of Blackjack has a lower house edge because it offers surrender and insurance features and allows you to split your hand up to 3 times.
Progressive Blackjack – This game features a side bet that goes to a progressive jackpot prize. You can win this jackpot by being dealt 4 aces of the same suit. Additionally, you may win other (lower) prizes for having 1, 2, or 3 aces.
European Blackjack – in European Blackjack, the dealer stands on a soft 17 and doesn’t peek for Blackjack mid-game. Players can only double down on hands with values of 9, 10, and 11, and can only split 10-value cards of the same rank (e.g. JdJc or TcTs).
Double Exposure Blackjack – Double Exposure Blackjack is a variant where both the dealer’s cards are exposed. To account for this rule, the dealer wins on all ties, except on blackjacks. A blackjack is paid at even money, and players may only split once.
High Roller Blackjack – High Roller Blackjack is simply a form of the game where the minimum and maximum betting limits are considerably higher than usual online Blackjack, which can be played from just $1 per hand.

Best Live Blackjack Providers

One of the best ways to evaluate an online blackjack casino is by looking at the quality of its game providers. Sites that partner with a variety of well-known developers are more likely to offer a high-quality gaming experience.

Some of the biggest names to look out for include:

Pragmatic Play – Since 2019, Pragmatic has produced high-quality live dealer games with innovative ideas, including ‘’deal now’’ and ‘’pre-decision’’ features. Its most well-known live Blackjack games are ONE Blackjack, Classic Blackjack, and Bet Behind Blackjack.
Playtech – Another industry giant, Playtech has three professional live studios where it streams a selection of blackjack games, including Ultimate Blackjack, Quantum Blackjack, and Mega Fire Blaze Blackjack.
Evolution Gaming – Considered the number one option among many players, Evolution Gaming is known for its high-quality streams and professionally run games. They offer a variety of games, including Infinite Blackjack, Power Blackjack, and Free Bet Blackjack.
Ezugi – A new kid on the block, Ezugi previously focused on creating high roller games such as VIP Surrender Blackjack and Blackjack Salon Privé, but has recently developed more accessible options. The company also recently introduced a new variant called Video Blackjack where all players can see each other through their webcams, creating a more social gaming experience.
Stakelogic – A live casino software provider that has released a variety of American and European Blackjack variants. It also has its own version of Lightning Blackjack called Super Stake Blackjack, where you can win up to 60 times your bet per hand.

How To Play Online Blackjack

While it may look complicated to begin with, playing online blackjack games is actually incredibly easy. Within a few minutes, you’ll be betting and doubling down like a pro. To help you get started, we’ve created a helpful walkthrough that you can use during your first online blackjack session.

Browse the list of blackjack games available at your casino.
Choose the title you’d like to play and click on the icon to load the game.
Read the rules of the game by clicking the information icon in the corner of the screen.
Select your bet size using the chip icons on the edge of the game.
Place your bets by clicking on the interactive game board.
Click the Deal button to start the game.

Once you start playing, you’ll need to make a decision on how to play your hand. After you’ve finished your turn, the dealer will play their hand. If your hand beat’s the dealer’s hand, your bet will be automatically paid out.

Blackjack Strategy

Blackjack is one of the few casino games that has strategic gameplay. The decisions you make while playing each hand affect your chances of winning or losing. Make correct decisions, and you can reduce the house edge to just 0.5%, but make incorrect decisions, and the house edge will increase.

The aim of the game is to beat the dealer’s hand while getting as close to 21 as possible without going over. If your hand total exceeds 21, you have busted, and you automatically lose your bet. There are a total of five actions you can make while playing blackjack, which are:

Hit – You take an additional card, increasing your hand total.
Stand – You end your turn without taking any additional cards.
Double Down – You double your bet at the cost of only taking one additional card. This action can only taken at the start of the hand.
Split – If your first two cards are the same rank, you can split them into two separate hands, doubling your total wager. These hands are played separately as standard blackjack hands.
Surrender – If the game allows it, you can decide to “surrender” your hand and receive half of your bet back.

To achieve the 0.5% house edge, you need to follow Blackjack Basic Strategy, which tells you how to play your hand against the dealer’s upcard. There are a number of basic strategy charts available online, giving you easy access to the game’s optimal strategy.

Expert Note: The optimal blackjack strategy varies depending on the rules in place. Before you use a chart, make sure it’s applicable to the game that you’re playing.

Online Blackjack Side Bets

As well as the main game, many blackjack titles offer side bets that payout based on the first three or four cards that are dealt. These side bets can offer significantly higher payouts than the standard game, making them an appealing option for players.

Some of the most popular online blackjack side bets include:

Perfect Pairs

In this side bet, you bet on your first two cards being a Perfect, Coloured, or Mixed pair. The winning combinations consist of the following:

Perfect Pair (for example, QhQh): 25 times your current bet.
Coloured Pair (for example, QhQd): 12 times your current bet.
Mixed Pair (for example, AhAs): 6 times your current bet.

The house edge on a Perfect Pairs side bet in Live Blackjack by Evolution is 4.1%.

21+3

With the 21+3 Blackjack side bet, you bet on your first two cards and the dealer’s first card making a vaild 3-card poker hand. The winning combinations are:

Suited Trips (for example, 4h4h4h): 100 times your current bet.
Straight Flush (for example, 7s8s9s): 40 times your current bet.
Straight (for example, 4d5h6c): 10 times your current bet.
Flush (for example, 2s,Ks,Js) 5x your current bet.

The house edge on a 21+3 side bet in Live Blackjack by Evolution is 3.7%.

Any Pair

When playing this side bet, you will win when your first two cards are a pair in the following way:

Suited Pair (for example, TcTc): 25 times your current bet.
Pair (for example, a 6h6s): 8 times your current bet.

The house edge on an “Any Pair” side bet in Infinite Blackjack by Evolution is 4.1%.

Hot 3

Another popular Blackjack side bet is the Hot 3 side bet. With this side bet, you win when the total of your two first cards plus the dealer’s upcard is 19, 20, or 21. The payouts are as follows:

7-7-7 (3 random 7s): 100 times your current bet.
Total 21 Suited (21 points in a single suit): 20 times your current bet.
Total 21 Unsuited (21 points in multiple suits): 4 times your current bet.
Total 20 (20 points total): 2 times your current bet.
Total 19 (19 points total): 1 time your current bet.

The house edge on a Hot 3 side bet in Infinite Blackjack by Evolution is 5.4%.

Bust It

If you place a Bust It side bet during online Blackjack, you’re predicting that the dealer will bust. This side bet is only available at some Live Blackjack games, such as Infinite Blackjack. The more cards the dealer draws, the higher your winnings will be:

8 cards or more: 250x your bet

6 cards or more: 50x your bet
5 cards or more: 9x your bet
4 cards or more: 2x your bet
3 cards or more: 1x your bet

The house edge on the Bust It side bet is 5.9%. Note that if you are dealt a blackjack, the game instantly stops and your Bust It side bet wager is returned.

Frequently Asked Questions About the Top Blackjack Sites 2023

As our casino experts regularly receive questions about the top Blackjack sites and they want the information on Casinofy as correct, objective, and inclusive as possible, they decided to answer the most frequently asked questions below.

Live dealer blackjack games are blackjack games that are run by real dealers that you can follow in real-time through a HD-quality live stream. These games offer a social element as you can communicate with the dealer and other players through the built-in chat feature, and, in the case of Ezugi’s Video Blackjack, even see other players.

You can play online Blackjack at many casino sites, including Winzter Casino, BetOnRed Casino and Tsars Casino. Check out our list of recommended options to find the very best places to play.

Yes, practically every online casino offers Blackjack. The most significant reason for this is because it’s a popular card game among online casino players thanks to its high RTP rate and engaging gameplay. A casino without Blackjack would be very rare to find in today’s day and age.

You should play online Blackjack because it is the most popular casino card game across the globe. It has the lowest house edge and features interactive gameplay where you have agency over the result of the hand. Added to this, there are many different variants available, including live dealer games, themed games, and modern games with multipliers and other features.

Yes, nowadays you can play online Blackjack on your Android or iOS device. All of our top-rated Blackjack sites have adapted to the huge influx of mobile casino players and have relaunched their games in HTML5 format, allowing you to play via your browser or a downloadable app.

Yes, you can play online Blackjack for free here at Casinofy or by registering at one of our Top Blackjack sites listed above. Many sites offer demo versions of their blackjack games, allowing you to try them out with zero risk to your bankroll.
