Unlocking Blackjack Card Counting Secrets

Understanding Card Counting in Blackjack


Card counting is a strategy used by players in blackjack to determine the probable advantage in the next hand by keeping track of the cards that have been dealt. Contrary to popular belief, card counting does not require genius-level intelligence. There are different card counting strategies, ranging from basic to advanced, each with varying levels of difficulty and accuracy. In this article, we will explore the concept of card counting, how it works, and the different strategies you can employ to enhance your chances of winning at blackjack.

What is Card Counting in Blackjack?

Card counting in blackjack is a method that allows players to keep track of the ratio of high-value cards (10, J, Q, K, A) to low-value cards (2, 3, 4, 5, 6) remaining in the deck. By maintaining a tally of these cards, players can make informed decisions on their bets and playing strategies. The ultimate goal of card counting is to reverse the casino’s edge and increase the player’s advantage in the game.

How Does Card Counting Work?

Card counting works by assigning a value (positive, negative, or zero) to each card in the deck. Players then keep a running count based on the cards that are dealt during the game. Once they have a confident grasp of the “true count,” which takes into account the number of decks remaining, players can adjust their bets accordingly. As the true count increases, it indicates that there are more high-value cards left in the shoe, giving the player an advantage and signaling them to increase their bets. Conversely, a decreasing true count suggests a higher concentration of low-value cards, favoring the casino and prompting players to lower their bets.

Basic Blackjack Card Counting Strategy

One of the most popular and easiest card counting systems for beginners is the Hi-Lo system. It assigns specific values to high cards (-1), neutral cards (0), and low cards (+1). By keeping a running count of these values throughout the game, players can estimate the likelihood of favorable cards remaining in the deck.

Learn the Most Popular Card Counting System – Hi-Lo

The Hi-Lo system breaks down the cards into three categories: high cards (10, J, Q, K, A), neutral cards (7, 8, 9), and low cards (2, 3, 4, 5, 6). High cards are assigned a value of -1, while low cards are assigned a value of +1. Neutral cards have a value of 0. By keeping track of the running count based on the cards dealt, players can make more informed decisions about their bets and playing strategies.

How to Count Cards in Blackjack with the Hi-Lo System

To count cards using the Hi-Lo system, start with a running count of 0 at the beginning of the game. As the cards are dealt, add or subtract the corresponding values of each card from the running count. This will give you an estimate of the ratio of high to low-value cards left in the deck. As the count increases, indicating a higher proportion of high-value cards, players should consider increasing their bets. Conversely, a decreasing count suggests a higher proportion of low-value cards, prompting players to bet less.

What is the ‘True Count’ in Blackjack?

In multi-deck blackjack games, online casinos add an additional layer of complexity by using multiple decks, making it harder to accurately assess the concentration of high and low-value cards in the shoe. This calls for the calculation of the “true count” which takes into account the number of decks remaining in the game. To calculate the true count, divide the running count by the number of decks remaining, rounded to the nearest half-deck. The true count gives players a more accurate assessment of their advantage in multi-deck games and allows for more informed betting decisions.


1. Can you make a living counting cards in blackjack?

Earning a living solely through card counting is possible but requires a combination of factors including unwavering bankroll management, extensive practice, solid card counting skills, and perfect strategy. However, it’s important to note that the profit margin from card counting is relatively small, usually around 1-2%. Additionally, players will need a substantial bankroll ranging from $20,000 to $50,000 to weather the fluctuations of the game effectively.

2. When should I bet when counting cards?

The betting pattern in card counting depends on the running count. Generally, as the running count increases, indicating a higher proportion of high-value cards, players should increase their bets. Conversely, a decreasing running count signals a higher concentration of low-value cards, prompting players to decrease their bets. It’s important to note that betting styles and sizes may vary depending on individual preferences and strategies.

3. Can you win blackjack without counting cards?

Yes, it is possible to win at blackjack without counting cards. There are several advantage-play strategies such as ace sequencing, edge sorting, shuffle tracking, and hole carding that can give players an advantage over the casino. However, these strategies require specific conditions and additional practice to master.

4. Is counting cards illegal in the US?

No, counting cards is not illegal under any local, state, or federal laws in the US. However, casinos are private establishments and have the right to ban players they suspect of counting cards, although it is not a criminal offense.

5. How difficult is it to learn card counting in blackjack?

The difficulty of learning card counting depends on the chosen system. The Hi-Lo system, for example, is relatively simple and easy to grasp, making it ideal for beginners. However, more advanced systems like the Omega II and Wong Halves require greater accuracy and precision, making them more suitable for intermediate and expert players. Practice, dedication, and attention to detail are essential for mastering any card counting strategy.
