Blackjack is one of the most popular casino games, and mastering card counting can give players a significant edge over the house. Although counting cards is often portrayed as a highly complex technique, it's actually quite accessible with the right understanding and practice. This guide will cover everything you need to know about counting cards, how to count cards in blackjack, and various blackjack counting systems to help you improve your game.
What Does Counting Cards Mean?
Before diving into the technical details of card counting, i's important to understand what counting cards means. At its core, card counting is a technique used by blackjack players to determine the probability of future hands being favorable. It involves keeping track of the cards that have already been played in order to estimate which cards are left in the deck, allowing the player to make better decisions about their bets.

Why Do People Count Cards?
The reason players learn to count cards is simple: to gain an advantage over the casino. By keeping track of high and low cards (which we'll discuss in detail), players can determine whether the next hand is likely to benefit the house or the player. This knowledge allows you to adjust your bet size accordingly, increasing bets when the odds are in your favor and decreasing them when they're not. I however highly recommend as a beginner to first stick with the blackjack cheatsheet before moving on to card counting.
Card Counting Basics: How Does It Work?
Card counting is a system where players assign values to certain cards and track these values as cards are dealt from the deck. The most common system is the hi lo counting system. In this system, cards are assigned the following values:
- Cards 2-6 = +1
- Cards 7-9 = 0
- Cards 10-Ace = -1
This is known as the hi lo card counting system. By tracking these values, you can estimate whether the remaining deck is rich in high-value cards (which favors the player) or low-value cards (which favors the dealer).
Hi Low Card Counting in Action
Imagine you're playing a game of blackjack, and the cards that have been dealt include a mix of low and high cards. You would keep a running tally based on the hi lo counting method, updating your count as new cards are dealt. If the count is positive, it means more low cards have been dealt, which increases the likelihood of high cards remaining in the deck. Conversely, if the count is negative, it suggests that high cards have already been played, which gives the house an advantage. To calculate this edge you could use our house edge calculator or use our blackjack calculator if you prefer to just play it simple.
True Count Conversion
When playing blackjack with multiple decks (which is common in most casinos), i's necessary to convert your running count into a true count. This is done by dividing the running count by the estimated number of decks still in play. The true count provides a more accurate measure of your advantage or disadvantage at any given point in the game.
For example, if you have a running count of +6 and there are three decks remaining, your true count would be +2. This true count is what you should use to adjust your bets.
How to Count Cards in Blackjack: Step-by-Step
Learning how to count cards playing blackjack requires practice, but the steps are straightforward:
- Learn the Hi Lo System: Memorize the card values in the hi lo card counting system.
- Start a Running Count: Begin tracking the running count as soon as cards are dealt.
- Calculate the True Count: If you're playing with multiple decks, divide your running count by the number of decks left.
- Adjust Your Bet Size: Increase your bet when the count is favorable (i.e., a high positive count), and decrease it when they're not.
By following these steps, you can consistently gain an edge over the house, as long as you remain focused and avoid detection by the casino.
Mastering the Blackjack High Low System
The blackjack high low system is one of the most widely used blackjack counting systems because of its simplicity and effectiveness. By assigning specific values to each card and maintaining a running count, players can predict when the house edge shifts in their favor, increasing the odds of beating the dealer.
In hi low counting cards, as the high cards (10s, Jacks, Queens, Kings, and Aces) are played, the deck becomes less favorable for the player. However, when many low cards (2-6) have been played, the remaining cards in the deck tend to favor the player, allowing for bigger bets.
How the Hi Low Count Works in a Card Game
The hi low count works by tracking whether more high or low cards remain in the deck of cards. As mentioned earlier, high cards are assigned a value of -1, low cards +1, and neutral cards (7-9) are given a value of 0. This simple system allows players to determine when the odds of winning increase and when to place larger bets, adjusting for multiple decks by calculating the true count.
Using the Hi Low System in a Casino
When it comes to casino counting cards, many professionals use the hi low count system because of its proven efficiency. Casinos, aware of this, often use countermeasures like shuffling more frequently or adding more decks, making card counting a bit more challenging. Even though card counting high low isn't illegal, casinos can still ask players to leave if they suspect hi low counting is being used.
Blackjack Card Counting Charts
A blackjack card counting chart is a helpful tool for beginners learning how to count cards in blackjack. These charts provide a visual reference for what counts to assign each card and can also show players when to bet based on the running or true count. By using a card counting chart, new players can visualize the process and better understand when the odds are in their favor.
Card Count Values and Betting Spread
The card count values you track directly influence your betting strategy. As mentioned, the hi lo system assigns positive or negative values to cards. A higher count means more 10s and Aces are left in the deck, which is beneficial for the player. At this point, players should increase their bets, a tactic known as a betting spread. For example, if the count is +3, you might double your bet, but if the count is +5 or higher, you could raise your bet even more.
Blackjack Card Counting Systems
The hi lo blackjack system isn't the only way to count cards, though it is the most popular. Other systems include:
- Hi Opt I and II: These systems are more complex than hi lo but offer potentially greater accuracy.
- KO System: This is an unbalanced counting system that doesn't require a true count adjustment.
- Omega II: A more advanced system that uses multiple card values for greater precision.
Each of these systems has its advantages and disadvantages, but for beginners, the hi lo system is the easiest to learn and use effectively.
How Hard Is It to Count Cards?
Many players wonder, how hard is it to count cards? While it requires practice and concentration, i's not as difficult as popular culture might suggest. Most players can master basic card counting systems like hi lo within a few weeks of dedicated practice. The challenge comes from maintaining your count in a noisy casino environment and ensuring that you don't raise suspicion with your betting patterns.
Casino Card Counters and Pit Bosses
Casinos are well aware of card counters, and they take measures to prevent players from gaining an advantage. This includes shuffling the deck frequently, using multiple decks, and having pit bosses monitor players who seem to be employing card counting strategies. Pit bosses are trained to look for players who adjust their bets too drastically or seem overly focused on the game, which are common signs of casino card counters. Online casinos are not great for card counting as they have too much decks, however if you would like to try it out you can use the online casino to practice.
Can You Get Banned for Counting Cards?
Counting cards isn't illegal, but casinos reserve the right to ban players they suspect of doing it. Casinos view card counters as a threat to their profit margin, and many famous card counting teams have been banned from casinos for winning consistently. The key to avoiding detection is to keep your betting patterns subtle and avoid making large, obvious jumps in your bet size.
