You've probably seen the movies. Some genius in a basement stares at a wall of monitors, memorizing every single card that flips over until they’ve basically hacked the universe. It looks like magic. Honestly? It’s just math, and not even the scary kind. If you can add and subtract one, you can count cards. But here is the thing: most people walk into a casino with a blackjack card counting chart burned into their brain and still lose their shirt because they don't understand the "why" behind the numbers.
Counting isn't about memorizing the deck. That’s a myth. You aren't Rain Man. You are just tracking the ratio of high cards to low cards. When the deck is fat with Aces and 10s, the player has the edge. When it's stuffed with 2s and 6s, the house is licking its chops. A chart helps you bridge that gap between "I think I have an edge" and "I know I have an edge."
The Hi-Lo System: Your Baseline for Every Blackjack Card Counting Chart
If you’re looking for the gold standard, it’s the Hi-Lo system. Created by Harvey Dubner in 1963 and later refined by Julian Braun and Stanford Wong, this is what 90% of professional counters use. It’s simple. It’s effective. It doesn't require a PhD.
Basically, you assign a value to every card. Low cards (2, 3, 4, 5, 6) are worth +1. They are "bad" for you when they are in the deck, so when they fall on the table, the "count" goes up, meaning the remaining deck is better for you. High cards (10, Jack, Queen, King, Ace) are -1. When you see a face card, the count drops. Neutral cards (7, 8, 9) are 0. They don't change a thing.
Why do 10s and Aces matter so much? Simple. You can't get a "natural" 21 without an Ace and a 10-value card. If the deck is rich in these, your 3-to-2 payout on a blackjack becomes way more likely. Plus, the dealer is forced to hit on 16. If the deck is full of big cards, that dealer is going to bust. Often.
Don't Forget the True Count
Here is where the average amateur gets wrecked. You’re at a table with six decks in the shoe. You’ve been counting for two rounds, and your "Running Count" is +6. You feel like a god. You shove your entire stack out there.
Wait.
A +6 in a single deck game is massive. A +6 in an eight-deck shoe with seven decks remaining is almost meaningless. You have to calculate the True Count. You do this by taking your Running Count and dividing it by the number of decks left to be played.
$$True\ Count = \frac{Running\ Count}{Decks\ Remaining}$$
If your running count is +6 and there are 3 decks left, your True Count is +2. That’s your real power level. Most blackjack card counting chart strategies only tell you to start ramping up your bets when the True Count hits +2 or higher. Anything less and the house still has a fractional edge or you’re basically playing a coin flip.
How to Read a Betting Correlation Chart
Expert players don't just guess how much to bet. They use a bet spread. This is essentially a chart in your head that dictates your wager based on the True Count.
Imagine your minimum bet is $10.
If the True Count is 1 or less, you bet $10.
At a True Count of 2, you might jump to $20.
At a True Count of 3, you're looking at $40.
By the time you hit a True Count of 5, you might be firing $80 or $100 per hand.
This is the "swing." You lose the small bets when the deck is neutral and hammer the casino when the math is on your side. But be careful. If you go from $10 to $200 in one hand, the "eye in the sky" (surveillance) is going to notice. Pit bosses aren't stupid. They look for "betting correlation." If your bets perfectly track the count, you’ll get a tap on the shoulder and an invitation to play any game except blackjack.
The Strategy Variations: Deviating from Basic
Everyone tells you to never, ever deviate from Basic Strategy. Usually, they’re right. Basic strategy—the stuff you see on those little plastic cards in the gift shop—reduces the house edge to about 0.5%. But once you start counting, the blackjack card counting chart changes.
These are called "Illustrious 18" deviations, identified by Don Schlesinger. They are the 18 most impactful moments where you should ignore basic strategy because the count is high.
Take the "Insurance" bet. Basic strategy says insurance is for suckers. It usually is. But if the True Count is +3 or higher, the deck is so loaded with 10s that taking insurance actually becomes a profitable move. Another big one is 16 against a dealer 10. Normally, you hit. If the True Count is positive (0 or higher), you stand. Why? Because the deck is heavy with big cards that will bust you.
Realities of the Modern Game
Casinos have fought back. It's not the 1970s anymore. You'll run into Continuous Shuffling Machines (CSMs) which make counting impossible because every hand is immediately fed back into the deck. If you see a machine that looks like a little whirlpool on the table, walk away. You can't win there.

Penetration is the other killer. That's how deep the dealer goes into the shoe before shuffling. If the dealer cuts off two decks out of six, your "Effective Count" is neutered. You want deep penetration. You want to see as many cards as possible before that plastic yellow card shows up.
Practical Steps for Mastering the Count
Stop trying to do it at a live table first. You'll fail. The noise, the cocktails, the waitress asking if you want a refill, the guy next to you complaining about his divorce—it's too much distraction.
- Master Basic Strategy First: If you can't play a "neutral" deck perfectly without thinking, you have no business counting. Use a simulator online until it's muscle memory.
- The Kitchen Table Drill: Take a single deck of cards. Flip them two at a time. This mimics a hand being dealt. Keep the running count. You should be able to get through the whole deck in under 30 seconds with a final count of zero.
- The "Casing" Method: When you walk into a casino, don't sit down immediately. Watch a table for a few minutes. Count from the sidelines. If the count gets hot, then sit down. This is called "Wonging in," named after Stanford Wong. It ensures you only play when you have the advantage.
- Manage Your Bankroll: Card counting is a long-term play. Even with a 2% edge, you can lose ten hands in a row. It’s called variance. You need at least 100 max bets in your bankroll to survive the swings. If your max bet is $100, you need $10,000 behind you.
Blackjack is a beatable game, but it requires discipline. The blackjack card counting chart is your map, but you still have to drive the car. Keep your head down, keep your bets reasonable, and for heaven's sake, don't act like you're in a movie. The best card counters look like the most boring people in the room.
To move forward, start by downloading a "Basic Strategy" app and practicing until you can play 100 hands with zero errors. Once that's settled, introduce the +1/-1 Hi-Lo values to your practice sessions at home using a physical deck of cards to build the tactile speed necessary for a real casino environment.
