Differences Between Blackjack Online & Online 21 Card Games

Blackjack is said to be the most popular casino game in the world, both online and offline, and because of this there have been a huge number of online variants for people to enjoy appearing across the internet. These variations and online 21 card games have been gradually increasing throughout the years, while remaining somewhat reminiscent to the classic table games that you can play online. Here we've put together a list of some of the different 21 card games that you can find online and the differences between them and online blackjack. If you want to take on the blackjack tables but you're looking for somewhere to start, then learn how to play the game with our basic blackjack guide. If however, you're looking to take your game to the next level and you've mastered the basics, then you can find out everything you need to know in our blackjack e-book, which gives you the skills to take on almost any blackjack or 21 card game variation. 

European Blackjack

This variant of the classic game is very similar, where a blackjack will always beat any other hand with a value of 21, and all face cards have a value of 10. During the game, a player can request up to nine additional cards with the term ‘hit'. The dealer will stand on hands with the value of 17, and if the player or dealers has a hand over the value of 21 then they will go bust. If the dealer goes bust then the player automatically wins. However, when the player and the dealers' hands tie, then this is known as a ‘Push' and the bets are given back with no wins or losses, and game play begins again. 

If the dealer has a blackjack, both original and doubled bets from the player are lost. An insurance side bet may also be offered depending on the table, which protects the player if the dealer has a blackjack (and is only offered when the dealer's initial card is an Ace). There are almost no differences between European Blackjack and classic blackjack, although each online blackjack table may have different side bets.


Pontoon is a popular online 21 card game, and while there are some roots in Pontoon that derive from blackjack, there are a few differences. One of the most significant differences is the use of terminology within the game. For example, in the classic version of the game you will hit to let the dealer know that you want another card, whereas in Pontoon this is known as ‘Twist'. Similarly, in blackjack you will ‘stand' if you do not want any more cards, and in Pontoon you will ‘stick'. 

There are a number of these terminology differences throughout the game, however the basic rules of Pontoon are very similar to the classic game of blackjack. Another difference in Pontoon is that if the player's cards are 14 or less, the player MUST twist, whereas in blackjack the player will always have to option to stand or hit when they want to. With other additional differences such as a tie being on a house advantage, the five card trick (a hand of five cards totalling 21 or less) and added mystery as the players do not see the dealer's first card, Pontoon is an exciting and very popular variant. 


Atlantic City Blackjack

In Atlantic City blackjack, there are two options: single hand and multi-hand. This normally has a lower house edge when compared to classic games of blackjack, but it is also a very similar game in that it is played with 8 decks of cards. The dealer will have two cards at the beginning, and checks for blackjack and if he has it, the game will be over before you can lose money by doubling. In this online blackjack variant, the dealer will always stand on a soft 17, you may double on any of the first two cards, and a double after a split is permitted depending on the table. In addition, you are able to then re-split cards into 3 hands, and the option for late surrender is allowed. 


Double Exposure Blackjack

This online blackjack game is very different from the classic variations, being played with 7 decks and both of the dealer's cards being dealt facing upwards. However, there are rules put in place to ensure that the player doesn't have too much of an advantage, creating a house edge of 0.69%. The dealer wins all ties except on a blackjack, and will always hit on a soft 17. Other differences in this game include that a player may re-split cards into four hands, and doubles are only permitted on hard 9, 10 and 11, as well as a double after a split being allowed. All player wins including blackjack will pay 1:1. 

Spanish Blackjack

This is possibly the most unique online 21 card game when compared to classic online blackjack, due to the fact that it is played with 8 Spanish decks of cards, consisting of 48 cards instead of 52. This makes the house edge 0.80% (when the dealer hits on soft seventeen) so it is important that if you are considering playing this variation, you should know every rule of the game. The dealer will peak on 10 and Ace cards for Blackjack and will hit on a soft 17. 

However, one bonus is that the player's Blackjack and 21 will beat the dealer's Blackjack and 21.  Late surrender is permitted and one may also Double Down on any number of cards, as well as after a split, however a player can only re-double down once. 

Bonus Blackjack

This game is the same as European Blackjack, but features an additional bonus option which means this game usually pays out a great deal more. Bonus Blackjack is generally played with 2 decks of cards, and if you bet on the bonus option, blackjack hands that feature a Jack and an Ace of Spades will pay out 50:1. With Jacks of any other suit accompanied by an Ace will payout at 25:1.
