Counting cards in blackjack

To know how the card counting system works in blackjack, the first thing you should do is be sure you know what this game is. If you think you’re not very clear, check out the article “Casino for newbies: games and tips” before continuing reading.
Card counting consists precisely in that, in counting which cards come out of the deck to know if you have more or less chance of winning. In other words, if you know which cards are left in the deck, you will know if there is more or less chance that the dealer will go over 21.
As for everything, there are many theories, but we are going to talk about the most common ones. Let’s go through steps:

High-Low or High-Low

This card counting system is the best known and practiced, and probably the one that most sounds to you.
The High-Low is an easy system to understand and to carry out, so do not worry if you were not the best in your math class. The method is based on the following table of card counting:As you can see, we divide the cards into three groups: from 2 to 6, from 7 to 9 and from 10 to ace and we give them values of +1, 0 and -1 respectively. With these values, if we add all the cards of the deck, the result would be 0.
The main objective of this method is to know if the cards that have not yet left and remain in the deck are high or low.
Imagine that the cards that remain in the deck are of great value. This situation will be favorable for the player, since he will know that the croupier is more likely to go over 21. In the same way, the advantage will be of the croupier if the cards that have not yet come out have a low value.
Keep in mind that if you do this calculation with two or three rounds, it will not be very accurate. The fewer cards left in the deck, the closer you will be to the real result.

Ace-Five or As-Five

This is the easiest card counting system, and therefore less effective. In him only the aces and the five are taken into account, that is to say, the cards that more and less value have within the deck.
The fives add 1 and the aces subtract 1. The rest of the cards in the deck are omitted without giving any importance.
The conclusion that is drawn from this method is that the higher scores will be better for the player. However, as we had already anticipated, the advantage that the player can obtain using this system is very slight.

This method is similar to the previous ones, but the difficulty to carry it out is greater. Instead of dividing the cards into three groups, we do it in 6 as shown in the following table of card counting.
El sistema no es excesivamente complicado, pero hay que recordar los valores y ser capaz de memorizarlos.
Aunque éstos son los más comunes, hay otros sistemas de conteos de cartas de blackjack que sólo vamos a mencionar. A continuación puedes ver la lista desde métodos simples hasta los más avanzados.

Counting in online blackjack

When we play online, we will not be able to use the same systems that we mentioned, because when starting each game a new deck is used.
To put it simply, in general, card counting does not make much sense in online blackjack.

Software for card counting

Internet advances with everything else, so there are card counting sofwares like “Flash”. Using this program is very easy, you will only have to tell him the cards that are coming out of the deck and he will do the calculations for you.
In addition, there are card counting simulators for both blackjack and texas hold’em that help you practice.
However, as we had anticipated, we can not trust these programs excessively. Whether we use a simulator or software to count cards, we probably can not apply it to the online casino where we are playing.

Is it legal to count cards?

In the same way that you organize certain calculations in your poker games, you can not forbid someone to make theirs in the 21st.
The counting of cards in blackjack is legal, but that does not mean that it is well received, much less that these types of practices are well seen in casinos.
If you are going to use some method: disguise. Casinos are private places, and although they can not prohibit you from doing calculations, they can ban you from entering, and you can ask Ben Affleck.
In the casinos surveillance is paramount, so at the slightest suspicion that you carry out this practice, you are out. Our advice is that if you use one, be the simple method and do it with care.


– Card counting will not make you rich, but if you know how to do it well you can make things easier on more than one occasion. Unfortunately in most cases life is not like in movies, so if you do not control, do not mess.
– Although we know that you always want to go further, our advice is to focus your efforts. To start, use the High-Low method, and do not change until you have it fully controlled.
– In addition, many casinos, as in online casinos, have continuous shuffling machines, which makes counting the cards meaningless.
So you do not forget the importance of the odds, we leave you this short video movie 21 Blackjack. Enjoy it!
