History of Blackjack

Blackjack may look modern but in fact, this gambling game has quite a long history. Of course, we can’t say the specific date when blackjack was invented but researchers say that the earliest references date back to 1700 when blackjack was firstly played in French casinos. The game was slightly different from the today’s online blackjack and was called Vingt-et-Un which means “Twenty-one”.

Another version says that the game was firstly mentioned by the Spanish writer Miguel de Cervantes in one of his novels about gamblers. According to the most optimistic opinion, the first gamblers to play blackjack were Romans who were doing it with the help of various wooden pieces.

Regardless of where the game was invented, blackjack was quickly spreading around the world with its rules being changed and improved. French colonist brought this card game to the North America where gambling got legal in 1931 and Nevada casinos opened their doors for gamblers. Casinos were attracting people with special bets featuring black jack and this is how the game got its modern name instead of “Twenty-one”.

RNG Blackjack

Random Number Generator (RNG) is a complex computation device that creates sequences of randomised numbers, this system is essential to the online gaming industry and especially for online gambling. RNG’s were implemented for a purpose, this is to provide complete fairness and unpredictability in the formulas that are presented in casino games, for example with blackjack casino sites the cards being dealt and the numbers that are shown are all at random every single time they are played, RNGs in blackjack online are specifically inputted to make sure that each game is played legitimately so each person has an equal chance of winning.

Live Dealer Blackjack

Whilst our technologies advance so can our forms of online gambling, another variation that was introduced was being able to play blackjack against a real live dealer, seeing them in front of you on your screen in real time and this would be conducted through a live video stream, this gives players a more realistic gameplay at home on their mobiles or laptops. To protect your privacy the dealer in live blackjack online will not be able to see you, they’ll be the only one on view which enables gamblers to feel more confident in trying and using that form of online blackjack.

Mobile Blackjack

If you are looking for the most excitement in a best online blackjack casino game and by far the most profit to win then high stakes blackjack is just for you. This game variation exists for the players that want to invest big money to win life-changing results back although, this version no doubt entails a greater risk of loss, therefore, practice and strategies are definitely advised prior.

Main Black Jack Online Types Explained

How to Play 21 Card Game or Blackjack Online?

Fortunately, we now don’t need to go to the casino to play 21 card game online. Whether you are in the United Kingdom or somewhere else, you can open the Online Casino HEX website to enjoy no download free blackjack or get redirected to one of the best online casinos for blackjack. And, what’s great, playing free blackjack online games is quite easy — you don’t need any special skills, just a little bit of luck and a couple of simple rules can bring you the winnings. But if you want to play 21 card game on blackjack sites, here is a step-by-step instruction to get you started:

  1. Choose your bet/wager. The first initial move you need to make, is to click on the chip you would like to place a bet with and drag it to the area it prompts you to place it in, whether you know all the values from previous online casino blackjack experience or not, the online version will have the amounts shown on the chips for you.
  2. Place your bet. After placing your bet, you can either keep the amount shown in the betting box or increase it, however, some online blackjack casino games with UK HEX Casino may not offer an option to do this until you either re-bet or place a new one.
  3. Deal the hand. Once your bet has been placed the casino blackjack game will start and the dealer will start dealing the cards. In order to establish your next move, you need to observe and memorize the card that you see the dealer has facing upwards. Luckily with online blackjack, you don’t have to do any quick calculations as it will show you the point value of your cards for you, this will help you with your next decision.
  4. Play your hand. There are several options you can choose to go with which is ‘hit’, ‘stand’, ‘split’ or ‘double’, this choice is all dependable on your preferred strategies. For example, if you decided to ‘stand’, which means you would like to keep with the cards and point value you currently have, you just need to click on to the button that says ‘stand’, this goes for all other options you have. In another scenario you could click ‘hit’ to increase your amount of cards and point value until you are happy with the value you have, then click ‘stand’ and the dealer will then take their turn.
  5. Hand Outcome. There are three outcomes that you could face once the dealer has taken their turn, these are Win, Lose or Push. If you have won the hand you will see on the screen a ‘Win’ sign pop up and also the amount you have won by, if the dealer has won the hand it shows the opposite with ‘Lose’ also stating that the dealer has won. On the other hand, if you and the dealer have the same final amount then this is classed as a ‘Tie’ or otherwise known as a ‘Standoff’, this causes your original bet to be returned.
  6. Play again. If you would like to continue the 21 card game then all you need to do is click the ‘rebet’’ button or the ‘new bet’ button, depending on the version of the game it may automatically reset for you. Choosing the rebet option will order the dealer to place the exact same bet that you originally asked for, this helps make it easier for you as a player and speeds up the process so you don’t have to keep manually inputting the same amounts. If you would like to play a different hand then all you need to do is click the ‘new bet’ option and this will accumulate a new refreshed table for you, ready to play again.

Main Rules & Terms

Even though the rules vary from one type of blackjack online game to another, the basics remain the same. As a gambler, you have one main goal — get more points than the dealer but not to exceed 21.

  1. Place your bet.
  2. You get two cards as well as the dealer. Cards values are as following:
    • 2-10 cards = cards number
    • Faces (Kings, Queens, Jacks) = 10
    • Aces = either 11 or 1
  3. Taking into account cards value, you decide to hit, stand, split or double down.
    • Hit means to draw one more card out of the deck and add its value to the total number of points.
    • Stand means to stop the game. You cannot draw cards out of the deck.
    • Split means to play two hands and got the new card to each of them. The split is possible when you have two cards of the same value.
    • Double down means to double the bet and take one more card.
    • Insurance – if the dealers facing up card is an ace then typically insurance on a bet is taken out. This is a different bet you can make where you have to guess if the dealer
    • Push – this is when both the player and dealer end up with the same amount of points and if so, the player won’t lose their bet nor gain any winnings.
  4. When the dealer shows his cards, you either win by getting more points or lose by getting fewer points. You also lose when you “bust” or go over 21 points.

Online Blackjack FAQ

How To Win Online Blackjack?

The first thing you should do in order to win blackjack online is research, look into how the game is played and study all the moves and terms as this initially gives you the natural advantage to conquer the game. With knowledge behind you, your next step could be to analyse all possible strategies you could use as these could end up being very rewarding and of course, what always helps is then practicing and gaining that experience. You must also pay attention to the game at all times, this is vital as one distraction could cost you money.

Can you Count Cards in Online Blackjack?

Card counting is a strategy which is based on mathematical probability, knowing how to do this enables you to work out if the next hand will go to your advantage or to the dealers. The card counting strategy is good and definitely useful when you are at playing online blackjack at casinos in person but, it is not at all the same for online blackjack as the cards are set to reshuffle automatically after every hand made and destroyed afterwards, this makes the penetration extremely low and the strategy completely inadequate and may likely cause more profit loss than any gain.
