Blackjack has long been considered one of the most popular and strategic casino games in the world. Unlike many other gambling games that rely purely on chance, blackjack offers an element of skill that can tip the odds in a player’s favor. One of the most well-known techniques for gaining an edge over the house is card counting. Though often portrayed as extremely complex and exclusive to prodigies, card counting is a learnable skill for any beginner who is willing to put in the time and effort.
TLDR (Too Long, Didn’t Read)
Card counting is a mathematical strategy used in blackjack to evaluate whether the next hand is likely to give an advantage to the player or the dealer. Beginners can start with simple systems like the Hi-Lo method to track high and low cards. Although legal, casinos frown upon card counting and may ban players they suspect of using this strategy. Mastery requires practice, quick mental calculations, and a calm demeanor.
What Is Card Counting?
Card counting is a technique used in blackjack to keep track of the ratio of high to low cards left in the deck. This allows players to make more informed betting decisions by estimating the probability of favorable cards appearing. The cornerstone idea is simple: when the deck has more high cards (10s, face cards, Aces), the player has a statistical edge. Conversely, a deck heavy with low cards favors the house.
The strategy doesn’t require memorizing every card played. Instead, players assign values to certain card ranks and keep a running tally known as the running count.
Is Card Counting Legal?
Card counting is not illegal under federal, state, or local laws in the United States. However, casinos reserve the right to refuse service to anyone. If you are caught card counting, the consequences could range from being asked to leave the table to being permanently banned from the casino. Despite this, many professional card counters continue to use the technique discreetly.
Basic Concepts Every Beginner Should Know
- Running Count: The ongoing total based on the cards that have been dealt.
- True Count: Adjusting the running count based on the number of decks still in play.
- Bet Sizing: Increasing or decreasing your bets based on the count value.
- Deck Penetration: The percentage of the deck that is dealt before reshuffling starts.
Let’s now go step-by-step through how a beginner can start to count cards.
Step-by-Step Guide to Counting Cards
Step 1: Learn the Hi-Lo System
The Hi-Lo system is one of the most popular and simple card counting strategies, perfect for beginners. Here’s how it works:
- Cards 2 through 6 are given a value of +1.
- Cards 7 through 9 are considered neutral and given a value of 0.
- Cards 10, face cards (Jack, Queen, King), and Aces are marked as -1.
Every time a card is dealt, the player adjusts the running count according to these values.

Step 2: Practice the Count at Home
Before stepping into a casino, players should become comfortable with maintaining a running count. One simple exercise is to flip through a deck of cards one by one and recite the running count out loud. A full deck should end with a final count of zero if you’ve done it correctly. With time, this step should take less than 25 seconds.
Step 3: Calculate the True Count
In multi-deck blackjack games, players must convert their running count into a true count. This is done by dividing the running count by the estimated number of decks remaining:
True Count = Running Count / Decks Remaining
For example, if your running count is +8 and there are 2 decks left in play, the true count is +4.
Step 4: Adjust Your Bets Based on the Count
The higher the true count, the higher the player’s advantage. When the count is favorable (e.g., above +2), it’s time to raise the bet. When the count is low or negative, the player should bet the table minimum.
This technique allows players to place larger bets only when they have the statistical advantage, maximizing potential profits and mitigating losses.
Step 5: Blend In
A key aspect of successful card counting is not drawing attention. Casinos keep a close eye on suspicious betting patterns. Players should avoid sudden large bets and maintain a casual demeanor. It can also help to mix up the strategy slightly or occasionally make “mistake” bets to throw off observations.
Tips for Success
- Start Small: Practice at low-stakes tables or even free online blackjack to build skill and confidence.
- Use Distractions for Practice: Train your count while doing other things, like watching TV, to simulate a real casino environment.
- Bring a Friend: Going with a partner can help you talk and act casually, making you less noticeable.
- Know When to Leave: If the casino begins to suspect you, it’s wise to walk away before being asked to.
Common Mistakes Beginners Make
- Trying to memorize every card: Not necessary. Stick to keeping a simple running count.
- Betting too aggressively: Large sudden bets attract attention. Always scale bets smoothly.
- Ignoring basic blackjack strategy: Even with a good count, bad decisions can wipe out potential gains.
- Panicking under pressure: Card counting takes practice to stay calm and confident under casino scrutiny.
Conclusion
Learning to count cards in blackjack isn’t just for geniuses or math wizards—it’s a skill that almost anyone can learn with dedication and consistent practice. While it doesn’t guarantee instant riches, card counting can reduce the house edge, turning blackjack from a game of luck into one of calculated decisions. For any beginner willing to put in the time, the world of card counting offers both intellectual challenge and the thrill of gaining an edge against the house.
