What Is Card Counting?
Card counting is a technique used in blackjack where players keep track of high and low-value cards that have been dealt. The primary goal is to predict whether the remaining cards in the deck favor the player or the dealer, allowing players to make more informed betting decisions.
How Card Counting Works
Card counting works by assigning values to different cards in the deck. Typically, cards are categorized as follows:
- Low cards (2-6) are assigned a value of +1.
- High cards (10-Ace) are assigned a value of -1.
- Middle cards (7-9) are considered neutral and assigned a value of 0.
As the cards are dealt, players maintain a “running count” by adding or subtracting these values. When the count is high, the deck is rich in high cards, which is advantageous for the player. Conversely, a low or negative count suggests that the remaining deck favors the dealer.
History of Card Counting
Origins of Card Counting
The concept of card counting can be traced back to the early 1960s, when mathematician Edward O. Thorp developed the first formal card counting system. His groundbreaking book, Beat the Dealer, introduced the world to the idea that blackjack could be beaten through mathematical strategy. Thorp’s system proved that, by keeping track of the cards, players could significantly improve their chances of winning.
Famous Card Counters
Over the years, several individuals and groups have gained fame (and fortune) through card counting. Among the most notable is the MIT Blackjack Team, a group of students from the Massachusetts Institute of Technology who used card counting techniques to win millions of dollars from casinos in the 1990s. Their exploits were so successful that they became the subject of numerous books and the Hollywood film 21.
How Card Counting Works: The Basics
Assigning Values to Cards
The most widely used card counting system is the Hi-Lo system. In this method:
- Cards 2-6 are assigned a value of +1, as these are low cards.
- Cards 7-9 are considered neutral and carry a value of 0.
- Cards 10 through Ace are assigned a value of -1, as they are high cards.
This simple arithmetic allows players to maintain a running count that reflects the composition of the remaining deck.
Running Count and True Count
The running count provides a basic idea of whether high or low cards are more prevalent in the remaining deck. However, to make the count more accurate in games with multiple decks, players convert the running count into a “true count.” This is done by dividing the running count by the estimated number of decks remaining. The true count gives a more precise indication of how favorable the deck is.
Betting Strategy
Card counters adjust their betting strategy based on the true count:
- When the count is positive, indicating a deck rich in high cards, players increase their bets. High cards (10s and Aces) are more favorable to the player because they increase the chances of hitting a blackjack or making strong hands.
- When the count is negative or neutral, players reduce their bets or even sit out the hand, as the deck favors the dealer in these situations.
Myths and Misconceptions About Card Counting
Myth: Card Counting Is Illegal
One of the most pervasive myths about card counting is that it’s illegal. In reality, card counting is not against the law. However, casinos are private establishments and have the right to refuse service to anyone they suspect of counting cards. This means that while you won’t get arrested for counting cards, you could be asked to leave the casino or be banned.
Myth: You Need to Be a Genius to Count Cards
Another common misconception is that card counting requires extraordinary mathematical abilities. In truth, the basic arithmetic involved in most card counting systems is within the grasp of anyone who can add and subtract single-digit numbers. The real challenge lies in the concentration and discipline needed to maintain an accurate count while playing in a noisy, distracting environment.
Myth: Card Counters Always Win
Card counting can shift the odds in the player’s favor, but it doesn’t guarantee a win every time. Like all forms of gambling, blackjack still involves a degree of luck and variance. Even skilled card counters can experience losing streaks, particularly over the short term.
Card Counting in Modern Casinos: Is It Still Viable?
Countermeasures by Casinos
Over the years, casinos have developed several countermeasures to reduce the effectiveness of card counting. These include:
- Using multiple decks: Most blackjack games now use between six and eight decks, making it harder to maintain an accurate count.
- Frequent shuffling: Some casinos shuffle the deck more frequently or use automatic shuffling machines, which effectively reset the count.
- Dealing only part of the deck: By not dealing the entire deck, casinos make it difficult for counters to reach a high or low count before the deck is reshuffled.
Reduced Effectiveness
Due to these countermeasures, the effectiveness of traditional card counting has been significantly reduced. While it is still possible to gain an edge, the margin is much smaller than it was in the past. Modern card counters must be more skilled and disciplined to achieve meaningful success.
Casino Surveillance
Casinos also employ advanced surveillance systems to identify and monitor suspected card counters. This includes facial recognition technology, behavior analysis, and tracking players’ betting patterns. Players who exhibit signs of counting are often subjected to increased scrutiny, known as “heat.”
Heat and Casino Bans
When a player is suspected of card counting, they might experience “heat” from the casino staff, meaning they are closely watched or approached by management. If the suspicion is confirmed, the player can be asked to leave or even banned from the casino altogether.
Alternative Strategies for Modern Players
Basic Blackjack Strategy
For most players, focusing on basic blackjack strategy is a more practical approach than card counting. Basic strategy involves making the mathematically optimal decision in every situation based on the player’s hand and the dealer’s upcard. While it doesn’t provide the same edge as card counting, it significantly reduces the house advantage.
Advantage Play Techniques
Some players explore other advantage play techniques like shuffle tracking (tracking cards through shuffles) or hole carding (seeing the dealer’s hole card). However, these methods are complex, difficult to master, and closely monitored by casinos.
Playing at Online Casinos
In online blackjack, card counting is not viable because the games typically use continuous shuffling after every hand. However, online players can still benefit from bonuses, promotions, and by employing basic strategy to improve their odds.
Should You Try Card Counting?
Considerations for Aspiring Card Counters
If you’re considering trying card counting, it’s important to understand the dedication required. Mastering card counting takes practice, patience, and the ability to stay calm under pressure. Additionally, the risks involved, such as being banned from casinos or facing scrutiny from casino staff, should not be taken lightly.
Alternative Approaches
For most players, alternative approaches like using basic strategy or enjoying blackjack as a recreational activity are more suitable. These methods reduce the stress and complications associated with card counting while still allowing for an enjoyable gaming experience.
FAQs
Is card counting legal?
Yes, card counting is legal. However, casinos can refuse service to players they suspect of counting cards.
How much of an edge does card counting give?
Card counting can give the player a small edge over the house, typically ranging from 0.5% to 2%, depending on the conditions.
Can you count cards in online blackjack?
No, card counting is not viable in online blackjack because most online games use continuous shuffling after every hand.

Beginners should start by mastering basic strategy before attempting card counting.
How do casinos detect card counters?
Casinos detect card counters through a combination of surveillance and behavior analysis. They monitor betting patterns, track players who alter their bets significantly, and use advanced technologies like facial recognition to identify repeat counters. Additionally, pit bosses and dealers are trained to watch for signs of counting, such as changes in a player’s behavior or betting strategy.
What happens if you get caught counting cards?
If you’re caught counting cards, the most likely outcome is that you’ll be asked to leave the casino and may be banned from returning.
