Online Blackjack Main Rules Explained

Blackjack online has more options to choose from than a land-based casino. There are often more types of bets for the players as well, which makes it a little extra fun to play online. Another difference is that you also have games of free Blackjack online and that the rules are different for the different variants so you can continue to play and see what works for you.

The Rules in Summary:

  • In Blackjack, you only play against the house
  • You should aim to get as close to 21 as possible to win, but not over 21
  • If you are closer to 21 than the house, you win

Here is a step-by-step guide on how to play blackjack online:

  1. Choose a casino and a game to play
  2. The game begins with you getting two open cards and the house either an open card or an open and a face down.
  3. This may differ between the variants.
  4. Depending on which cards have come up, you decide whether you want to stay (Stand) or take a new card (Hit).
  5. If you choose to stay, you win if the house card is lower or over 21, otherwise, you lose if you go over 21.

Card Value

The value of the cards is different in online blackjack and in casinos, this can be confusing at first but you learn this quickly. Normally, the face up cards have a higher value in ascending order from jack to Ace of the highest value. The other cards clearly have their value in the number printed from 2–10. In Blackjack, all face up cards have a value of 10, Aces are worth 1 or 11 and 2–10 have their usual value.

Understanding Blackjack Main Features

Blackjack Main FeaturesIt’s important to get as close to the sum of 21 as possible and to have a higher hand than the house, without getting bust. Getting bust means that the sum of the cards exceeds 21 and is counted as a loss for both the house and the player. The player receives two cards and can choose whether he is happy with them or wants more cards.

Online blackjack is relatively easy to learn. We recommend playing blackjack free before trying with real money.

Best Bonuses for Online Blackjack Players

When you make a deposit, you can sometimes be rewarded with a bonus penny to play with. It’s usually a bonus that matches your deposit up to a certain amount. Unfortunately, table games rarely contribute much to the turnover and often they can not be used at live casinos.

If you can play classic casino games like blackjack, you usually have a very low maximum limit on your bets. Always read the terms and conditions before accepting a bonus so that you are sure that you can play online blackjack with it or scout for blackjack-specific bonuses.

Know Your Odds Against the Dealer

In blackjack, you should always calculate probabilities or odds. What are the chances that you’ll get a certain card versus what the dealer or house might get? There are tables for what the odds look like for winning at hit/stand for different cards against the dealer’s face-up starting card.

Probability to bust on an extra card

The probability of getting a bust naturally increases the higher the value you have on your cards. If you already have 21, you should definitely not take another card. If you are at 11 or below on your hand, it is impossible to get fat, ie 0%.

It’s the numbers between these that are interesting and that should be evaluated before you decide to stay, hit, or surrender. If the odds look very good compared to what the dealer has, it may be time to double.

12 31%

15 58%
16 62%
17 69%
18 77%
19 85%
20 92%
21 100%

The dealer's probability to bust

You have to take the dealer's face-up cards into account when calculating the odds for the end of the hand. Here it gets a little more difficult as the rules change in the different variants of Blackjack. For example, you need to think about whether the dealer must stop or can take a card on a 17 to get a correct picture of the odds.

Dealer’s card Probability when standing on 17s Probability when hitting on 17s
Ace 17% 20%
2 35% 36%
3 37% 38%
4 40% 40%
5 42% 42%
6 42% 44%
7 26% 26%
8 24% 24%

  • Double Down on 8 Against Dealer

    Double Down on 8 Against Dealer’s 5 or 6 Upcard in Single Deck

    If you are holding an 8, you should double up because 5 and 6 are low for a dealer to hold.

    Split a Pair of 8s and Aces

    Hit a Hard 12 against the Dealer’s 2 or 3 Upcard

    Most people go to hit if it is allowed, we say take cards, you lose less in the long run even if you get a bust sometimes.
  • Blackjack

    Hit Ace-7 (Soft 18) When the Dealer’s Upcard Is 9, 10, Or Ace
