Types of blackjack rulesets online

Each online casino hosts games from different software providers, with popular blackjack developers being Microgaming, Net Entertainment, BetSoft, Ezugi and Evolution Gaming. Games by each of these developers come with different rules and variations, so it always pays to play around at different casinos and try different blackjack games to see which one you like most. Here are just a couple of the most popular blackjack variants you’ll find at our recommended casinos:

  • NetEnt Blackjack Pro Series
    NetEnt’s most popular blackjack series comes in standard, low-limit, high-limit and VIP versions, catering to all bankrolls. Players can choose to play from one to three hands against the dealer, with the option of placing an additional double Jack side bet. NetEnt’s Pro Series Blackjack uses premium animation, set to a soothing soundtrack of smooth jazz to set the scene.
  • Microgaming Atlantic City Blackjack Multi-Hand
    This American Hole Card game allows you to play up to five hands at once using classic Atlantic City Blackjack rules including the dealer peaks for blackjack and dealer must stand on all 17s. Doubling down and late surrender is allowed, and a natural blackjack plays 3 to 2. Micorgaming blackjack is available in both instant-play mode and using downloadable software.
  • BetSoft American Blackjack
    BetSoft is the leader in true cinematic 3D gaming, and their American Blackjack game is a firm player favourite. Six decks of cards are used and you can play up to three hands at once. The rules of standard Vegas Strip Blackjack are used, except the player may only split once, there’s no late surrender and the player may double only on a hand of 10 or 11. Bets start from a minimum of $1 and carry a maximum of $100, making it suitable to low-stake and high-stake players.

Other popular variants of 21 you’ll find online include:

  • Single Deck Blackjack
  • Double Exposure Blackjack
  • Super 7 Blackjack
  • Vegas Strip Blackjack
  • Vegas Downtown Blackjack
  • Spanish 21
  • Pirate 21
  • Pontoon
  • Perfect Pairs Blackjack
  • Super Fun 21
  • Playboy Live Dealer Blackjack
  • Live Dealer Blackjack Party

What is live dealer blackjack?

Live dealer blackjack is fast becoming the hottest way to play online twenty-one. These are games hosted by real people from real casino studios and streamed via video feed straight to your computer in real time. Just like when playing RNG (random number generated) blackjack, you still place bets with the use of computerised chips and the click of your mouse, but you get to watch the croupier accept your bet and then deal the cards so you can watch the results unfold.

Live dealer casino games are hosted by professionally trained, good looking croupiers and streamed from high-end studios designed to replicate glamorous land based casinos, recreating the ambience and social aspects of the casino experience straight to your computer.

House edge and odds in online blackjack

When proper strategy is used, blackjack carries some of the best odds of all casino table games. However, with so many variants available, the house edge can change significantly depending on the rules of the game in play. When ideal blackjack rules are in place, the house edge sits around the 0.25%-0.28% mark, but this varies dramatically based on the inclusion or good or bad blackjack rules by the casino vendor.

Favourable rules for players to look out for

A great advantage to playing 21 online is you can pick and choose which game you play, not being restricted to the rules offered in a land based casino. This means you can shop around until you find a blackjack game with rules working in your favour. Here are some of the favourable rules to look out for when playing online blackjack:

  • Single deck – the fewer decks of cards in play, the lower the house edge becomes and the better your odds of winning. When playing with 52 cards rather than the 416 cards used when eight decks are in play, the house edge becomes a player-friendly 0.48%.
  • Double down after split – when a game allows you to double down after splitting cards, the house edge decreases by 0.14%.
  • Hit on split aces – it’s rare a game allows you to hit after splitting aces, although you may find American Blackjack games online which allow you to draw on any split hand, lowering the house edge by a nice 0.19%.
  • Split up to four hands – games allowing you to split up to three times for a total of four hands brings a player advantage of 0.10%. This favourable rule can usually only be found in variants of Atlantic City and Vegas Strip blackjack.
  • Double down on any two cards – American and Spanish blackjack variants often allow us to double down on any two cards (unlike Australian casino blackjack which only allows a double down on hands of nine, 10 or 11) bringing an additional 0.09% advantage to the player.
  • Surrender after doubling – some variants of Pontoon and Spanish 21 allow a double down rescue, where we can surrender after doubling to forfeit a portion of our original wager and complete the hand, bringing the house edge down by another 0.10%.
  • Late or early surrender – although rare, some online 21 games give the option of surrendering before or after the dealer peeks for blackjack, which can reduce the house edge by a huge 0.24%.
