This page is your practical starting point. If you are brand new, focus on understanding the basic idea first: blackjack becomes more favorable when there are more tens and aces left to be dealt. That helps players make more blackjacks, it increases double-down value, and it can also make dealer busts more likely in certain spots.
Before you spend time on counting systems, make sure your basic strategy is solid. Counting without basic strategy is like trying to drive faster before learning how to steer.
What Card Counting Actually Does
Most counting systems assign simple values to cards as they are dealt. The most common version (Hi-Lo) looks like this:
- 2 through 6 = +1
- 7 through 9 = 0
- 10, J, Q, K, A = -1
You keep a running count as cards come out. When the running count is positive, it usually means more high cards remain. When it is negative, more low cards remain. In multi-deck blackjack, players then convert the running count into a true count by dividing by the estimated decks remaining. The true count is what serious players use to size bets and make strategy adjustments.
That sounds simple on paper, but the real challenge is doing it accurately while playing at full speed, talking to a dealer, handling chips, and staying calm.
Important Reality Check Before You Learn
Card counting is legal in many places because you are using your brain, not a device. That said, casinos are private businesses and may still refuse service, limit your play, or back you off if they think you are an advantage player. If you want the short version of how casinos respond, read how casinos stop card counting and what a blackjack backoff looks like.
Also, counting works best in the right games. Bad rules can erase a lot of your edge. Always check the table rules first:
- Prefer 3:2 blackjack over 6:5
- Look for dealer stands on soft 17 (S17) when possible
- Double after split (DAS) helps
- Late surrender helps when available
- Good penetration matters (how deep into the shoe the dealer deals)

How to Learn Card Counting Step by Step
1) Learn perfect basic strategy first
Do this before anything else. Counting gives you a small edge only if your basic decisions are already strong. Use a chart or a blackjack strategy wizard and drill until your decisions feel automatic.
2) Pick one beginner-friendly count
For most players, Hi-Lo is the best starting system. It is not the fanciest count, but it is proven, practical, and easier to use in real games than many advanced systems.
3) Practice a running count at home
Take a single deck and count through it one card at a time. Your goal is to end at zero. At first, ignore speed. Accuracy comes first. Once you can consistently end at zero, start timing yourself and try to get faster without making mistakes.
4) Learn deck estimation
In shoe games, you need to estimate how many decks are left. This is the part beginners usually avoid, but it matters. A running count of +6 means something very different with six decks left versus one deck left.
5) Convert to true count
Practice quick division in your head. Example: running count +6 with about 2 decks left gives a true count of +3. You do not need perfect math to the decimal; close, consistent estimates are usually enough.
6) Add bet sizing discipline
Do not jump from one unit to a giant bet just because the count rises. Build a simple, repeatable betting ramp and stick to it. Counting works over many hours, not one hot shoe.
7) Add strategy deviations later
Once your count is accurate, then start learning index plays (like when to stand, hit, or take insurance differently than basic strategy). If you try to learn everything at once, you will mix things up and slow your progress.
If you want to train properly, use a card counting trainer and work on one skill at a time: count accuracy, deck estimation, true count conversion, and then deviations.
Popular Blackjack Card Counting Systems
There is no single “best” system for everyone. Some systems are easier to learn, while others aim for more betting or playing efficiency. The right system is the one you can use accurately under pressure.
Below are the major systems covered on Counting Edge. If you are new, start with Hi-Lo and branch out only after you have experience.
- Hi-Lo (beginner)
- KO / Knock-Out Count
- Zen Count
- Advanced Omega II
- Hi-Opt I
- Hi-Opt II
- Revere Count
- Silver Fox
- Uston APM
- Uston APC
- Uston SS
- Canfield Expert
- KISS II
- Kiss III
- Canfield Expert
- Red 7
- REKO
- Revere
- True Count
- Zen Count
Many advanced systems can look impressive on paper, but they come with more mental load. A simpler count used accurately will usually beat an advanced count used poorly.
Running Count vs True Count
This is one of the biggest beginner mistakes. Players learn the running count and think they are done. In multi-deck blackjack, you usually need the true count.
- Running count: The raw total as cards are dealt
- True count: Running count divided by decks remaining
Example:
- Running count = +8
- Decks remaining = 4
- True count = +2
A true count of +2 is positive, but it is not the same as a true count of +8. That difference matters for bet sizing and deviations. If you want a deeper breakdown, read our page on true count conversion.
When to Raise Bets and When to Stay Small
The basic idea is simple: bet more when the true count favors the player, and keep bets smaller when it does not. The hard part is discipline. New players often:
- bet too aggressively too early
- increase bets based on emotion instead of the count
- use a spread that is too obvious for the table
- forget table minimums and bankroll limits
Your betting plan should match your bankroll and the table conditions. Start with a conservative spread until your accuracy is reliable. A count is only useful if your decisions stay consistent when the table gets noisy or the shoe gets tense.
Common Card Counting Mistakes
Trying to count before learning basic strategy
This is the most common mistake. Fix your foundation first.
Going too fast in practice
Speed without accuracy is wasted practice. Train accuracy first, then speed.
Ignoring casino conditions
A good count system does not fix bad rules, poor penetration, or a 6:5 game.
Playing too long when tired
Fatigue leads to counting errors and bad betting decisions. Short, focused sessions are better than marathon sessions.
Making obvious bet jumps
Huge bet swings can attract attention quickly. Learn to play within your bankroll and your comfort level.
Expecting instant results
Counting is a long-term edge. You can do everything right and still have losing sessions.

How to Practice Card Counting at Home
A simple practice routine works better than random practice:
- 5 minutes: basic strategy flashcards or chart review
- 10 minutes: single-deck running count drill
- 10 minutes: shoe drill with deck estimation and true count conversion
- 5 minutes: review mistakes and repeat the weak spots
Keep a small notebook or spreadsheet. Track your time, error rate, and how quickly you can count a deck accurately. Progress is easier to see when you measure it.
Is Card Counting Worth It?
For most casual blackjack players, basic strategy gives the biggest improvement with the least effort. Card counting is worth learning if you enjoy the process, like practicing, and want to understand the game on a deeper level.
If you are only looking for “easy wins,” counting will probably feel like too much work. If you like skill development, discipline, and long-term improvement, it can be a rewarding part of blackjack.

Card Counting FAQ
Is card counting illegal?
In many places, no. Using your brain to track cards is generally not illegal. Casinos can still refuse service or back you off, so always follow local laws and casino rules.
Can you count cards online?
Usually not in standard RNG blackjack because each hand is independent and shuffled by software. In live dealer games, conditions vary, and many casinos use countermeasures that make counting difficult.
What is the easiest card counting system to learn?
Hi-Lo is the most common beginner system because it is simple, practical, and well documented.
Do I need to learn true count conversion?
Yes, for most multi-deck games. The running count alone is not enough to estimate advantage accurately in shoe blackjack.
Can I learn card counting without a trainer?
Yes, but a trainer speeds things up because it helps you practice accuracy, speed, and true count conversion in a more structured way.
Hi, I’ve read over and tried most of the counts you have listed and would like to consider one more (as a casual player, just looking to not walk away in the negative). From what I gather, OPP or Speed Count, may be the easiest of them all to simply give me at least an even game. I’ve not yet read an explanation that clicks with me though. As I understand I count 2-6 as a +1 and then subtract the current number of hands dealt. I’m having trouble grasping where the tipping point is though. From what I’m reading elsewhere you would start increasing your bets as the count goes over +12….but it seems that by the end of the shoe you would have really HIGH counts??? Lets say you got up to a +40…Sorry, just having a hard time wrapping my head around it.
Hey, Jerry! Thanks for being a Counting Edge reader and for asking a great question. It seems that all card counters are on a perpetual quest for that perfect method that works for them. We certainly hope you find yours!
Our enthusiasm about the OPP card counting method is a little mild, to be honest. Trust us when we say you aren’t the first person that has had trouble wrapping their head around it. Even though it proclaims itself to be an easy method, those claims can be deceiving. To begin, many explanations of this count have you beginning the count at +6 when a new shoe is begun. It is a lot easier to determine the tipping point when a negative number is bad and a positive number is good. Next, you not only have to assign point vaues to the cards as they are dealt, you also have to count the total number of hands that are played. We just can’t see it being that much more effective than a simpler count which starts at 0 and just adds a point value to low and high cards. Like the KISS method, for example. In a live blackjack game when the action is fast and furious, having to count each hand in addition to the cards can be overwhelming.
Now, with that being said, have you thought about using this method in an online casino that uses live dealers? You might be able to get a game where there aren’t too many other players at the table. This seems like a good way to give the count a test to see if it might work for you. At the very least you can practice doing all the counting that this system requires. If you decide to give it a try, let us know how it works out. Good luck at the tables!
Hello there I want to ask some more questions…If I follow omega 2 or hi low or any system is it worth to just play the favourable count rounds and not even sit at negative?Are there any default numbers or should I figure this out alone with experience from playing
Hey, Kostas. Thanks for the question. Believe us, making profits from playing blackjack would be much easier if a player could only jump in when there is a positive count. Sitting out negative rounds would be awesome, but it’s almost impossible to do this in live blackjack unless you are working as a team. If you sit at a table and only make a bet when the count is high, pretty soon the casino will mark you as a counter. At that point it is game over. The best you can do is to keep your bets at the minimum while the count is negative, and if the count stays low you should look for another table. It is possible for you to get a count from a new shoe in many cases before you enter the game, but some casinos forbid mid-shoe entry. This is especially the case in double-deck or single-deck blackjack games. As far as a default count goes, you are correct in stating that experience is the best teacher. It all depends on your goals and what you are striving to make. For some people, jumping in when the count is +3 or better is adequate. For others, that number may be +8. Just remember that waiting on a higher number means you’ll have fewer opportunities in a session to make a big bet. On the other hand, the profits you make from those bigger bets will tend to be larger. Hope this makes sense. Good luck at the tables!
