Introduction
Card counting is one of the most well-known strategies in blackjack. While often romanticized in movies, it’s a real and legal method that skilled players use to gain a slight edge over the house. Though casinos frown upon it, counting cards is not cheating—it’s simply a mental technique that tracks the ratio of high to low cards left in the deck.

What Is Card Counting?
Card counting is a technique used to determine whether the next hand is likely to give an advantage to the player or the dealer. It involves assigning values to cards and keeping a running total as cards are dealt. A higher count means more high cards (10s, face cards, Aces) remain in the deck, favoring the player. A lower count indicates more low cards (2–6), favoring the dealer.
Why Card Counting Works
Blackjack is unique among casino games because previous outcomes affect future ones. After cards are dealt, they are not returned to the deck immediately. This creates a predictable pattern that skilled players can use. When high-value cards remain in the deck, players have a better chance of hitting blackjack and winning big bets.
The Hi-Lo Card Counting System
The Hi-Lo system is the most widely used method because it strikes a balance between simplicity and accuracy.
Assign Values to Cards:
- 2–6 = +1
- 7–9 = 0
- 10–Ace = -1
Step-by-Step Process:
- Start at a count of zero when a new shoe (deck) begins.
- Add or subtract based on each card dealt to players and dealer.
- Maintain a running count as cards are revealed.
- Divide the running count by the number of decks remaining (this gives the “true count”).
- Increase your bet when the true count is positive and decrease it or sit out when it’s negative.
Understanding the True Count
Why It Matters:
The true count adjusts the running count based on how many decks are left. This helps standardize your advantage regardless of shoe size.
How to Calculate:
True Count = Running Count ÷ Number of Decks Remaining
For example, if your running count is +6 and about 3 decks remain, the true count is +2.
When to Adjust Your Bets
- True count +1 or lower: Bet the table minimum
- True count +2 or higher: Increase your bet gradually
- True count +4 or higher: Maximize your bet (within your bankroll strategy)
Important Note:
Avoid extreme bet jumps that draw attention from casino staff. Gradual increases help stay under the radar.
Tips for Successful Card Counting
-
Practice Often
Use card counting apps or physical decks at home. Aim for speed and accuracy under pressure. -
Blend In
Don’t stare at the table or mouth the count. Engage in small talk and vary your behavior like a typical casual player. -
Stick to One System
Avoid switching between methods mid-game. Master one system like Hi-Lo before exploring others. -
Use Team Play (Advanced)
Some players use a team strategy where one person counts and signals a “big player” to bet when the count is favorable. This method was famously used by the MIT Blackjack Team. -
Know Casino Countermeasures
Even though counting is legal, casinos may ban or limit players suspected of card counting. They may:
- Shuffle early
- Ban mid-shoe entry
- Ask you to leave
Always remain respectful and discreet.
Conclusion
Card counting is a time-tested method that gives skilled blackjack players a small but real edge over the casino. It requires practice, discipline, and discretion. By understanding and applying systems like Hi-Lo, you can turn blackjack into a more strategic—and potentially profitable—game.
