The various types of Blackjack

To date, although the game of Blackjack is always the same, there are different types of the game of 21 that must absolutely be known. Here are the three most popular versions:

  • Blackjack in the traditional casino: Obviously we talk about the game sitting at a real green table, for example in Las Vegas, or in one of the American terrestrial casinos.
  • Software online: is the version you will find in online casinonull It is played against a PC, even if certifying the random distribution of the cards is the RNG, i.e. the Random Number Generator. Thanks to this, you will always know you are safe from any scams and scams of all kinds.

How many decks of cards are in the Blackjack

Obviously Blackjack is played with a deck of French cards without joker. The number of decks changes according to those who manage the game. Usually they range from two decks up to eightnull In traditional casinos, for example, there is always a number of bouquets quite other, while in the software games in authorized online casino, the number can also be lower.

Initially the blackjack in traditional casinos was played with one or two decks, even if a very particular problem began to take over. That is the number of players who counted the cards trying to take advantage, and managing very often, from the cards released in the previous handsnull In practice, as we said before, the cards with a high value are really important, also because only thanks to them is it possible to get high points. In the same way, then, even knowing if the deck is still rich in small cards, it can be useful when you have a low point with the first two cards and there is a need for another card. The fear, in fact, is always the one that can come out a more card that makes you get busy or lose, but if you are sure that in the deck there are more small cards than high, then it will be easier to go on.

This system became famous especially in the 80s and 90s in the Las Vegas casino And it was certainly not accepted in the right way by dealers who saw people or groups of people win thousands of dollars every evening thanks to this system.

Casino solutions

In addition to intimidating people, the casino had to undertake some action to remedy the ever growing number of people who counted the cards. And for this they decided to increase the number of decks present during a game, bringing them even up to eight (in total there are therefore 416 cards) and use automatic mixers. The latter serve to speed up the mixing of the cards which therefore could take place even after each lap.

In traditional casinos, and even during live games, in fact, there are two types of mixing:

  • Automatic: The cards are positioned in a sabot and this provides very few according to mixing the various decks. It is certainly the fastest mode.
  • Manual: It will be the dealer to mix the cards manually. Obviously he cannot do it after each game and therefore he will do it only when the cards come to the size, or the black plastic card that is used to score where the deck has been cut. Once the cards are played and you reach the cardboard, then mix.

For players who want to take advantage of the Blackjack decks, the fact that they mix manually is certainly an important point since it allows you to countnull Of course, the casino, introducing a large number of decks of cards have tried to interrupt this practice, according to their fraudulent even if someone who uses it is still there.

In the latter case it would be possible to count the cards even if in reality there are equally different difficulties. First of all you must always be attentive to every hand that comes out and you cannot lose even one. In addition, the number of cards is really high and therefore the possibility of being able to understand if the maximum is loaded (i.e. there are many high value cards) or I unload (with multiple small cards) è really impossiblenull And maybe once you have almost managed to understand it you get to the size and therefore you have to start all over again.
