Card counting (also commonly referred to as card reading) is a strategy often used in blackjack so that players can decide in advance whether the next hand is beneficial to the player or the dealer. Card counters usually try to reduce the house edge of the casino by paying extra attention and paying close attention to all the cards drawn during the game. If knowing which high and low cards have been dealt, the player can calculate the probability next to the next card drawn from the deck. Therefore, if you choose to use this card counting strategy, once you master the technology, you can win large sums of money.

The story of counting

The mathematical genius Dr. Edward O. Thorp is considered one of the creators of the card counting strategy. He managed to lay the foundation for playing cards and was used by many blackjack players in the 20th century. His "Beat the Dealer" published in 1962 contains the cornerstones of strategy, but it also contains several different theories about how to play blackjack strategically. Thorpe was far ahead of his time in many ways, and he was also one of the first to publish a theory and introduce it to a wider audience.

Another famous name in the development of card counting is Andy Bloch. Today, he may be the most successful poker player. However, Bloch was also a member of the MIT Blackjack team and released a DVD with card counting instructions; defeated Blackjack. Bloch also participated in David Layton's documentary "The Hot Shoe", which was released in 2005 and also involved blackjack. In the film, David Layton interviewed card counters such as Edward Thorp and Andy Bloch. During the film creation process, Leiden used the knowledge he gained from interviews and bet the film budget of $5,000 as a case study.

Other celebrities who are important in developing blackjack strategies are; Stanford Wong (author of "Blackjack Career"), Kent Utson (author of "Million Dollar Blackjack") and Arnold Snyder (author of " Blackbelt in Blackjack).

Advantages and disadvantages of counting cards

In our case, all types of cheating must be considered illegal. This includes "past releases" and "base transactions". This also applies to all auxiliary devices, such as mirrors or mobile apps that can help cheating. A typical example is Keith Taft and his son, who became famous in the 1970s when they designed a portable mechanical device that could count cards (see picture).

On the other hand, card counting is just another way for players to think strategically throughout the game. And most importantly, everything, so counting cards is not illegal. This way, you have no reason not to count cards, but we strongly recommend that inexperienced players do not try this in the casino, because if you are inexperienced, the casino will detect you more easily. In other words, we really don’t want the casino to detect you when you count the cards.

Since online casinos use "random number generators", counting cards in online casinos is almost useless, so 100% of all numbers are randomly generated. In a physical casino, before the dealer reaches the cut of the deck, several hands can be played in blackjack, and then the cards must be shuffled. Here, the counting card is really effective!

How to count cards in blackjack

Once the first card is issued, the card counter will start counting the value of the card. Low-value cards will be added 1 point. A high-value card will deduct one point from your current count. All cards from 7 to 9 are considered neutral and therefore will not be counted in this high and low card.

Here is an example of card counting in a random round of blackjack:

Player 1 Player 2 Player 3 Player 4 Player 5 Dealer

Brief: A, 5 6.2 7.8 Q, Q 3.8 9

Count: -1, 1 1, 1 0, 0 -1, -1 1, 0 0

After this particular round, your total will be 1. There are a few low-value cards, which means there are more high-value cards left in the card. As you may already know, after only a few rounds, the count will not be very accurate. Once you have collected a lot of information, your count will be more accurate, which will give players a better advantage.

When you try to calculate yourself for the first time, you can choose to use a set of cards and calculate all cards. If your count is correct, it should end up at 0 after you have counted all cards. The first few times are not easy, but if you practice a lot, you can quickly learn to count very accurately. After a while, you can try to count two cards at the same time, which will make it more realistic compared to a real blackjack game.

If you train for long enough, you will find different combinations of cards, and then the counting will proceed almost automatically. This is the amazing thing about simple high and low counting. A more complex card counting system will be introduced later, but most card counting experts agree that the advantages of simple and easy-to-use technology are far greater than more accurate but also more complex technologies.

Card counting technology in blackjack

High and low system

Using this high-low strategy is the most profitable and perhaps one of the easiest ways to count cards. This system is actually a continuous counting technique in which a specific value is assigned to the card. The system is used to distinguish the balance between high-value cards and low-value cards remaining in the pile.

High-value cards such as 10s and ace will not only increase the probability of blackjack, but it also means that two high-value cards are missing on the deck. A pile of cards (most of which are high-value cards) is very beneficial to the player because it increases the probability of the dealer going bankrupt. On the other hand, if most of the remaining cards are of lower value, then the dealer here will have an advantage because it is more difficult to break a card with 2-6 cards. Since there are many low-value cards left, the player must hit at 12-16, so when the cards are dealt, the probability of the dealer going bankrupt is greatly reduced. If there are still a lot of high-value cards (10s and Aces) in the pile, the probability of the dealer going bankrupt is greatly increased.

True count

Another factor to consider when trying to determine the balance of playing cards is the number of remaining playing cards. As we said before, as we get closer to the bottom of the game, your count will become more accurate. If you divide your count by the approximate number of cards remaining, then you will get a more accurate count-also known as the "true count".

Converting your current count to "real count" will make your count more accurate. However, this may be difficult, but if you practice multiple sets of cards, at some point you will be able to see approximately how many cards are left.

Suppose your current count is 4 and you bet that there are 2 sets of playing cards left, then your "true count" will be 4/2 = 2.

If your result is still positive, then you will most likely get a huge profit, which means you need to increase your bet on the bet. The "True Count" number can more accurately indicate how good a pile of cards is.

More complicated blackjack card counting system

Since the counting card was first invented, people have been trying to improve and change various counting card technologies. However, we have learned from experience that if the system is very simple, it will also be easier to use. Even if you think you are mastering a complex and very precise system, in the long run, you will not make more money from it, which is why it is best to stick to simple practices.

The disadvantage of more complex systems such as "side count" and "multi-level" is that when you try to track many different information, this interferes with your ability to play quickly and count accurately. If you play fast with simple strategies, you will make more money than slow-played cards with complex and advanced strategies. If you are easy to count cards, it is more likely that the casino will not detect that you are counting cards when playing blackjack.

Countdown or charge

One of the most famous techniques for counting cards is "Wonging", which is named after the pseudonym Stanford Wang, which was used by John Ferguson in his book series about blackjack. As mentioned earlier, the term "Wonging" refers to his technique of observing the game table and counting the cards, but using this method, he only starts playing the game when he sees that the remaining cards in the game have an advantage. .

This approach will reduce your "operating costs", which means it won't cost you anything if you choose to sit at the "hot" table. However, this technique is well known, which means that the casino staff will quickly detect whether you are standing and counting the cards while observing the game table. In addition, there are many casinos that no longer allow players to participate in a set of cards, but you have to wait until the cards are shuffled again and you don't know if there is an advantage.

The obvious advantage of a "countdown" system such as "Wonging" is that the player does not have to play all the hands he/she counts. This will reduce the volatility of your budget, thereby bringing more revenue to players.

Can I count the cards?

In movies and TV series, card counting is described as very easy to learn. The concept of card counting gives the impression that if this method is used, the player will always win. But don't be fooled, because reality is much more complicated than what they describe in movies and TV series. However, learning and realizing your own game card counting is still very realistic.

If you ask our experts on CasinoSlots, then we believe that when you play the game, card counting is just a kind of strategic thinking. This is like a poker player who decides to go all-in, once he/she determines the possibility of winning is in the player's favor. Therefore, we believe that when blackjack players believe in their position, they are likely to increase their bets, and the next card may have a positive impact on the player. If you manage to combine a good blackjack strategy with bulletproof card counting, you will have a huge advantage compared to the casino, which means you can use your knowledge to win large prizes on the table.

Card counting in physical casinos

Although it is legal to use this strategy, our experts at CasinoSlots do not recommend that you use this strategy in physical casinos, because this strategy is not popular and it may also get you out of the casino! Although playing cards is only more illegal than calculating your probability of being at the poker table, many casino behaviors seem to be illegal. Since casinos are considered private land (at least in the U.S.), they have the right to deny players access to the casino (therefore, they recommend treating card counting as an illegal activity). When we say that the casino will use these rights as soon as it sees players counting cards at the table, trust us.

Casino counterclaim

Card counting has been around for many years, and some of the first books on the subject were published in the early 1960s. Casino staff have long tried to prevent these activities around gaming tables. Here are some attempts by casinos to stop counting cards:

Cutting card

The first thing the casino tries is to use "cut cards" so that the entire card is not played. This "cutting card" separates a pile of cards, and after reaching this "cutting card", you will shuffle the cards again here.

Multiple sets of playing cards

Casinos have also begun to use multiple sets of playing cards in the game, although the number of sets is not important to the use of the Hi-Lo method described earlier.

Casino's own card counter

Today, casinos use several automated systems to detect dishonest gambling. Some casinos scan all cards before issuing them to blackjack, so the casino actually counts the cards. When they know that a pile of cards is unbalanced, they compare this information with the irregular betting on the table. If a player systematically raises or lowers his bet through points, the casino can detect this behavior through its system, which may indicate a card count. Then, the player will be asked to leave the casino or be asked to play in a casino that does not require specific skills.

Microchips and chips

Another common way that casinos can detect betting violations is to insert microchips into gaming chips. This makes it easy for the casino to collect information about the amount bet on the table. This may seem an exaggeration, but remember that casinos have used surveillance cameras for decades, and their overall goal is to make money-not to distribute money to players who think they are smarter than the casino.

Face recognition

One of the latest technologies in casino surveillance is a program that can recognize faces. The facial recognition camera can identify the deceived player by storing the deceiver in the database. When you enter the casino, the camera scans all guests. Due to the use of these new cameras, the famous card counter may be required to leave the casino before he/she even reaches the blackjack table.

How to avoid attracting attention when counting cards

We strongly believe that the best way for casinos to not find you is to use a simple technique in which you will spend a lot of time learning this strategy in order to finally perfect this simple strategy. The best card counters are probably not mathematical geniuses, but they may only know how to count and then try to blend with their surroundings so as not to attract unnecessary attention.

If you practice using our ticket counting coach, then you will undoubtedly become a better card counter. When you have to learn to blend with your surroundings in the casino, this is what you have to learn from yourself. However, one thing is certain. If you are good at counting and are born to you, it will be much easier for you if you want to try it at the casino. Now we can only hope that one day we can hear your legendary bonuses at the blackjack table-or even better; we will never hear them!

Therefore, a simple strategy is more profitable

If you use a simple strategy when ordering cards in the casino, the casino will be less likely to detect you when you play the game. If you are playing with a team, this is easier to spot for cameras in the casino. If you use gestures and codes while playing, even if you are sure they will not be detected, they will definitely be captured by the surveillance camera. If they are not discovering it for the first time, they will undoubtedly find it when the casino staff sees the video.

On the other hand, if you play the game alone, the camera will never be able to capture what is happening in the player’s mind. This may be the biggest reason. Even the most technologically advanced casinos still have difficulty detecting the best card counters. For example, once you choose to share your strategy with others, if you need help, you will leave a trace at the casino to help them find you.

Most casinos try to detect card counters by observing irregularities in betting. This can be done manually or using technology. If you use a simple card counting system, you can focus on blurring the track, for example, if you start communicating with other players at the table. You can also make slight adjustments to the pattern to ensure that no one suspects counting cards when playing blackjack.

Card count in the team

Of course, a single player can only play one hand at a time. Therefore, it seems a good idea for a person to choose to participate in team competitions to increase temporary income.

The team game has been used by the M.I.T. Blackjack team. This is a series of students from the Massachusetts Institute of Technology who later became the inspiration for Kevin Spacey's movie "21". The most famous strategy in team games is to have players sit at different tables and play the game. When a big bet is placed, the player sends a signal to the other members of the team. The advantage of participating in team matches is that you can only choose to bet big money if you know that the table is good for the players.

One disadvantage of teamwork is that this is a fairly large business, and there is a great risk of being discovered, because more people are involved, and everyone wants a pie. Casino employees will also be more aware of players jumping from one table to another and playing a lot of games, which in turn simply emphasizes how risky the casino is to be discovered.

If you still want to participate in team competitions when you need to count cards, or just want to know how it works, then there is a classic working structure:

The Back-Spotter

This is a member of the team and does not have to sit in certain seats. The guard will look at the table from a distance, and then he/she can signal to other team members (or gorillas) when they need to sit on the table.


The members of the team are active players at the table, but the most important job for that member is to accurately calculate the number of game piles on that particular table. Casinos often check whether there are irregular bets on the table, which means that the "San Da" must bet in a minimum amount. He/she must send a signal to the group's gorillas, and then the gorillas will enter the game and make a large number of bets. Note.


Gorillas are not known for their mathematical skills, which also means that gorillas do not have to count cards. On the contrary, the member of the group moves from one table to another, and when the table is hot, he/she is here to exert his/her best ability. A typical gorilla character is a full of millionaires. He throws large sums of money from table to table, which seems foolish.

Big player

The members of the team must ensure that no other members of the team are detected. High-stakes players with blackjack ability will undoubtedly attract the attention of casino staff. You must keep in mind that it is not illegal to develop a perfect strategy, because such a technique allows a budget-savvy player like Gorilla to attract attention before the rest of the team is discovered.
