Introduction to Blackjack

Two cards showing blackjack and some colourful chips

Blackjack is a card game that has been around for centuries. It’s quite an easy game to learn, but a difficult one to really master. While learning the ins and outs of the game, you might stumble on some blackjack terms and rules in the beginning. But after a short while, we promise it will feel like a breeze to play this fun and quick casino game.

In blackjack, it is you against the dealer. There might be other players sitting around a blackjack table, but your only opponent is the dealer – the casino itself. This makes it all the more exciting as if you play your cards right, you can lower the house edge and beat the casino. All you have to do is to have the better hand out of the two of you.

How To Play Blackjack for Beginners

Let’s start with a quick introduction to how the game works. The aim of blackjack is simply to have a better hand than the dealer, and this all depends on the sum of your cards. The hand value is counted by adding up the cards you have at hand, based on the following blackjack card values:

The card suit does not matter, only the number/letter. The best hand you can have is one with the value of 21 (a blackjack). But be aware that if you get anything more than 21, you “go bust” and lose. Therefore you want to be as close to 21 – without going over.

To start the game, both you and the dealer get two cards each. Both of your cards will be visible, but only one of the dealer’s cards will be face up. The other one is placed face down, hidden. This gives the house an advantage, as you don’t know how many points the dealer is starting out with and if they have an Ace hidden under there.

How to Play Blackjack Online: Virtual or Live?

At land-based casinos, blackjack will be played at a table where cards are dealt and bets added. Apart from the lack of physical cards and tables, online blackjack works exactly the same way as described above. You will be playing against a dealer and the aim is to be tactical on how many cards to draw in order to get as close to – but not over – the sum of 21.

When playing at online casinos, you will have many more different game versions to choose from than tables available at a physical establishment. Two main categories you will meet when it comes to blackjack online are virtual vs. live games.

Virtual casino games are the traditional types of online casino games. Here you will see a video on your screen with virtual cards being dealt. This means you are playing against “a machine” rather than a real dealer as it is all in-game and virtually developed. The outcomes are all random and you use buttons to make your choices such as requesting another card or not.

With live blackjack, the technology of virtual games is combined with modern streaming technology to give the best of both worlds. Here you will still see a video on your screen, but the difference is that it will be live-streamed and real-life. A real person (dealer) will lead the game in a game studio somewhere and then the experience is streamed directly to you in the game. This allows you to see, interact with and play against a real person without having to travel to a casino as it is all online.

Which game type and version you would like to play is up to you. We recommend trying a few different games to find out what you prefer!

Make use of Online Blackjack Promotions

In addition to online blackjack and other casino games evolving quickly and offering unique versions, there are many perks of gambling online. One of them is that most online casinos offer many bonuses and promotions. And at the best blackjack sites, you can of course take part in unique blackjack promotions!

Blackjack promotions can be anything from blackjack bonuses such as money to spend on blackjack games exclusively to blackjack tournaments and more. There might for example be a tournament with a leaderboard and price pool. By finding and participating in these promotions, you can get more bang for your buck and win large prizes. So check the promotions page of your casino or check our casino news for the best deals of the week.
