Card counters are quick to point out that there are no laws in America restricting the use of card counting as a strategy for winning at blackjack. Unfortunately for card counters, there doesn’t have to be a specific law for casinos to keep people who count cards from walking through the front door. The Idea Behind Card Counting. The whole idea behind card counting is to determine how rich or poor the shoe is at any time with cards favorable to the player or the dealer. A shoe rich in high cards (tens and aces) is favorable to the player, while a shoe rich in low cards (2s through 6s) is favorable to the house. Moreover, the amount of variance in Blackjack means that card counting can prove a fruitful method only in the long run, after hundreds of hours of play. With that in mind, let’s begin. Initially introduced in the distant 1963, the Hi-Lo card counting is the most efficient.
Card counting is one of the most famous advantage-play methods in gambling. In fact, a number of Hollywood movies include card counting scenes or are based entirely on this technique.

Skilled counters can gain anywhere from a 0.5% to 1.5% edge over the house, which leads to good profits over time.
Given card counting’s fame, the mainstream population and even many blackjack players themselves think that this is the only way to gain an edge.
But the truth is that you don’t have to count cards to beat blackjack. Instead, you can use one of several other advantage-play techniques to win.
I’m going to discuss how hole carding, shuffle tracking, ace sequencing, and edge sorting can help you beat the game. I’ll also discuss if any of these advantage-play methods are better than card counting.
Hole Carding
Blackjack dealers at North American casinos deal themselves one face-up and one face-down card. The face-down card is referred to as the hole card because it’s not visible to players.
The dealer is the only person at the table who sees the hole card, because they check for a natural blackjack before players act.
Given that you don’t see the hole card, you’re basing blackjack decisions on incomplete information.
Basic strategy helps you narrow the gap between the house and yourself. But you’re still at a slight disadvantage when using perfect basic strategy.
Enter hole carding: an advantage-play technique that involves spotting the dealer’s hole card. If you see their hole card, you can gain up to a 13% advantage.
Any dealer who consistently offers players a chance to see this is called a “flasher.” These dealers, through one mistake or another, allow players to gain a big advantage by flashing their hole card.
The best way to spot these dealer flaws is by sitting in the right seat and paying close attention to every hand.
Most players don’t pay attention to when the dealer peeks for blackjack or deals themselves the hole card. But by doing so, this gives you a tremendous advantage at a flasher’s table.
Spotting the dealer’s face-down card when they peek for a blackjack is called “first-basing” or “third-basing.” Spotting the hole card when it’s slid under the up-card is called “front loading.”
Many hole-carders sit at first base, which is the first seat to the dealer’s left. This gives you the best chance at seeing a right-handed dealer’s hole card.
The other popular hole-carding seat is third base, which is to the dealer’s immediate right. This is the best spot to see a left-handed dealer’s face-down card.
It also helps if you can gain a vantage point closer to the table felt. The more level your eyes are with the table, the better chance you have of seeing the hole card.
Shorter players have an advantage in this regard because they’re naturally closer to the table felt. Taller players often lean back to improve their vantage point.
Of course, the key is to do so in a subtle manner. Being obvious about leaning back or slouching draws attention to your hole-carding efforts.
Another thing that you need to be careful of is over-using your advantage. Sometimes you should ignore the info you gain when using basic strategy because some plays look too suspicious.
Here’s an example.
- Your first two cards total a hard 8
- The dealer’s up-card is a 10
- You see that the dealer’s hole card is 2
- The optimal play is to double down against the dealer’s 12
- But no regular player is going to make this decision because they’re not supposed to have this info
The last thing that you want to do is continue taking advantage of plays like this, especially when your dealer is a consistent flasher.
If the casino finds out that a dealer is consistently flashing cards and helping a player(s) win, one of two things will happen.
- 1. The dealer will receive better training
- 2. The dealer will be fired if flashing becomes a consistent problem
In either case, the work you put into finding a flasher goes out the window. And this is hardly worth taking advantage of a few suspicious plays that you should let go.
Players need to think long term and realize what kind of profits they can make by continuing to play at the dealer’s table. Avoid decisions that are too far outside the bounds of regular strategy.
It’s hard to find a consistent flasher. Casinos train dealers on how to deal without giving players a chance to see their hole card.
Nevertheless, some dealers either don’t pick up enough skills in training or become lackadaisical over time.
The best place to start when looking for flashers is casino-heavy cities like Las Vegas, Atlantic City, and Reno. This enables you to bounce from casino to casino within a single shift.
Odds are that you’re not going to find a flasher within your first few hunts. But once you do find one, note what shift they work and make it a priority to play at their table.
Shuffle Tracking
In the 1960s and ‘70s, Las Vegas casinos began implementing shoe games. The idea was to hinder card counters by forcing them to count through multiple decks in each shoe.
Casinos thought that they solved their card counting problem with shoe blackjack tables. But card counters merely adjusted their strategy, and other techniques such as shuffle tracking were born as well.
Shuffle tracking refers to tracking specific cards, or a sequence of cards, through multiple shuffles. Shuffle trackers monitor where 10s and face cards (a.k.a. high cards) are throughout the coming rounds.
Much like card counting, the goal is to bet more when the shoe is abundant in high cards. When used properly, shuffle tracking is much more effective than counting.
But this technique is also very difficult to use, because you must know an advanced strategy on top of card counting.
The basic idea behind shuffle tracking is that shuffles aren’t random, and you can track certain cards after a shuffle.
You might think, “Can’t dealers just shuffle more to make decks more random and stop shuffle trackers?” But many casinos don’t like their dealers wasting too much time with shuffles, because this slows the game and lowers profits.
Blackjack dealers commonly use a “zero shuffle,” where cards are separated into piles, with the shuffling only being done between the piles (i.e., the dealer grabs two piles and riffles them). This means that the ace of hearts, for example, would have a high chance of only being in one or two sections of the shuffled shoe.
Card counting comes in because you want keep track of the count in different discard sections. I’ll start this explanation by looking at the point values assigned in the Hi-Lo counting method.
- 2 through 6 = +1
- 7 through 9 = 0
- 10 through ace = -1
You can use other card counting systems with shuffle tracking. But the Hi-Lo is a popular counting strategy that’s easy to use.
Counting Rule Examples
As you may know, high cards favor the player by improving their chances of getting a natural blackjack payout. This advantage comes from the fact that players get either a 3:2 or 6:5 bonus with a natural.
Meanwhile, low cards reduce the dealer’s chance of busting out while they try to reach a hard 17. Anything that increases the dealer’s odds of winning is bad for players.
The premise is to make higher bets when the shoe is rich in aces and 10-value cards (i.e., positive count) and bet the table minimum when the shoe contains more low cards (i.e., negative count).
![Card counting rules dice game Card counting rules dice game](https://upload.wikimedia.org/wikipedia/en/thumb/c/c9/Video_Blackjack_Machine_at_Seven_Feathers.jpg/250px-Video_Blackjack_Machine_at_Seven_Feathers.jpg)
The overall positive or negative count is referred to as a “running count.” But Hi-Lo system users convert this into a “true count,” which accounts for the number of unplayed decks in the shoe.
Here’s an example:
- Your running count is +8
- There are 4 decks remaining
- 8/4 = +2 true count
Card counting and shuffle tracking come together when players have a good idea of what card values are left in the shoe based on their count. If they can take this a step further by visually tracking high cards and finding them bunched together, they gain an even greater advantage.
One big benefit of shuffle tracking is that it’s harder to spot than card counting.
Sure, you’re still increasing bets during favorable situations. But your increased bets come in a shorter span once 10-value cards and aces emerge in clumps.
Another advantage is that you can gain up to a 50% advantage with perfect shuffle tracking.
No player will have this edge all of the time. But an expert shuffle tracker may gain between a 10% and 30% long-term edge, depending upon the dealer and shuffling style they’re using.
The downside is that shuffle tracking is extremely difficult to pull off. You not only need to keep a good count, but also follow the deck with your eyes and understand how high cards will disperse after shuffles.
Be prepared to practice for quite some time in order to become an expert shuffle tracker. Even then, you need to be good enough to pull this off with a high degree of certainty.
In other words, some players fool themselves into thinking that they’re gaining an edge, when they’re really not doing anything special.
Another drawback is that not every casino trains their blackjack dealers in a shuffle that can be exploited. Some casinos use a 2-pass shuffle, where they go through two rounds of riffling and restacking.
2-pass shuffles make it harder to track cards during a shuffle. Ideally, you want a one-pass shuffle to cut down on the randomness of the shoe.
One more point worth making is that you can’t shuffle track with a continuous shuffling machine (CSM). That said, look for hand-shuffled shoes with one-pass shuffles.
Ace Sequencing
Ace sequencing is a different type of card tracking, where you try to remember what cards are on top of the ace in the discard pile. You then make larger bets when you see these cards come out in hopes of being dealt an ace.
Like shuffle tracking, ace sequencing is a difficult pursuit. The best ace trackers can remember up to a dozen card sequences in each shoe, thus greatly improving their chances of catching aces.
If you know that you’re likely to be dealt an ace, you can gain up to a 50% advantage on the house. When you’re dealt an ace, you have a 31% chance of getting a 10-value card and completing a natural blackjack.
Spin palace casino download. But becoming a great ace tracker is hard because there’s not many materials on the matter – unlike with card counting. Additionally, it takes a while to learn how to properly execute this concept.
Ace sequencing begins with watching discard segments so that you can guess what clumps might appear intact after a shuffle. You also want to watch where aces go into the discard tray, so that you have a good idea on when an ace will be dealt in a segment.
Finally, you want to remember 2-3 cards that are placed on top of the ace in the discard try. Dubbed “key cards,” these are what you watch for after the deck is shuffled.
You then increase your bet when you see the key cards and can anticipate an ace being dealt.
But keep in mind that ace sequencing is just like shuffle-tracking in that it doesn’t work when your table has a CSM.
Edge Sorting
Edge sorting is an advantage-play technique that was popularized by poker pro Phil Ivey. Along with his partner Cheung Yin Sun, Ivey won over $20 million collectively from Crockfords and the Borgata.
Lawsuits ensued, and the court sided with both casinos on the matter. But this was only after Ivey’s case was heavily scrutinized by casino security.
That said, it’s theoretically possible for blackjack and other card players to win money with edge sorting.
This technique involves spotting flaws on card backs and using this information to predict card values before they’re revealed.

But you can’t just walk into the casino and expect to find a flawed deck to take advantage of. Instead, you need to know about design flaws in specific manufactured decks and determine where these decks are used.
This is how Cheung was able to help Ivey win millions of dollars. She analyzed a purple Gemaco deck for hours and became good at spotting the design flaws.
These flaws often come in the following form.
- One side of certain card backs will feature half-diamonds on the edge
- Other cards may have full diamonds on the edges
- These flaws are easiest to spot when the flawed side is rotated towards you
- The goal is to figure out which values have an irregular diamond pattern on the back
Edge sorting works best when cards are rotated 180 degrees because this makes it easier to see the diamond patterns. This is why Ivey specifically requested that cards be rotated 180 degrees under the guise of superstition.
But Ivey is a high-stakes gambler who can make these kinds of requests. The average player doesn’t have this sway and won’t have a chance with edge sorting.
Unless you’re a high-stakes blackjack player, then you can’t gain an advantage through this technique through special requests. Even when you can make these requests, casinos will be on guard due to the fame associated with Ivey’s case.
Do Any of These Advantage-Play Methods Beat Blackjack?
All of the blackjack advantage-play techniques covered above can give you a greater edge than card counting.
You can gain up to a 50% advantage in the case of both shuffle tracking and ace sequencing. Hole carding can also give you a nice edge worth up to 13%.
I can’t find exact figures on what advantage a player can gain with edge sorting. But based on how well Ivey did, I’m assuming that you can earn over a 20% advantage with it.
Compared to all of these techniques, card counting is a much tougher grind. The average skilled card counter only gains a 1% advantage.
This means that you’ll experience almost as many losing sessions as you do winning ones. Because of this, card counters need large bankrolls worth $30,000 or more to survive variance with any degree of certainty.
But the good thing about counting is that it’s easier to pull off than any of the methods I covered above. Furthermore, you can find more blackjack games that are susceptible to card counting.
Contrast this to hole carding, shuffle tracking, ace sequencing, and edge sorting, where you need much more specific conditions to win.
I’m not saying that you shouldn’t try these advanced strategies. This is especially the case with hole carding, shuffle tracking, and ace sequencing, which work with great success in the right games.
But be aware that you’ll need to put in more work with these techniques to properly use them.
Conclusion
You’ve likely heard stories of card counters getting kicked out of casinos. In fact, the movie 21 dedicates multiple scenes to the casinos’ pursuit of the MIT Blackjack Team.
The same holds true of any other blackjack advantage-play method you use, whether it be hole carding, shuffle tracking, or edge sorting.
Casinos are private establishments that can refuse service to blackjack players. And if they determine that you’ve gained an advantage in any form, they’ll ask you to leave.
This makes it important to blend in and act like a normal player if you do gain an advantage. If your edge is large enough, you might even consider messing up a few plays just to look like an average recreational player.
Above all, make sure that you have an advantage first. Then you can concentrate on a persona to use to avoid casino detection.
But before you embark on a quest to become a pro, I recommend playing some low-stakes blackjack while you figure the game out.
You can use basic strategy while keeping an eye on the dealer’s hole card, flawed decks, or shuffle-tracking opportunities. This is a nice way to transition from being a regular player to getting an edge on casinos.

Introduction
Let me say loud and clear that card counting is hard and is not as rewarding as television and the movies make it out to be. If it were an easy way to make money, then everyone would be doing it.
If you do not know the basic strategy, trying to count cards is highly ill-advised. Experienced card counters still play by the basic strategy the great majority of the time.There can be no short cut around learning the basic strategy, those who attempt card counting without a firm foundation in the basic strategy are making a big mistake.
To be a successful counter you have to be able to countdown a deck fast and memorize large tables of numbers as well as make it look like you're just a casual player.Furthermore, with today's rules, a realistic advantage the counter will have is only 0.5% to 1.5%. You will not win money slowly and gradually but your bankroll will go up and down like a roller coaster in the short run. Only in the long run, over hundreds of hours of playing, can you count on winning.
The underlying principle behind card counting is that a deck rich in tens and aces is good for the player, a deck rich in small cards is good for the dealer. When the counter knows the odds are in his favor, he will bet more, and adjust his playing strategy to stand, double, and split in some plays where basic strategy says to stand. All the options the player has at his disposal favor the player even more when the deck is ten and ace rich. Here is a list and a brief reason why.
Card Counting Rules Games
Standing: The player may stand on stiff totals of 12 to 16, and the dealer may not. In ten-rich shoes, hitting stiff hands becomes more dangerous, favoring the more conservative player strategy.
Insurance: On average, when the dealer has an ace up, the remaining cards in blackjack will be 30.87% tens (based on a six-deck game), making insurance a bad bet. However, if the probability gets above 33.33%, it becomes a good bet. Counters know when the remaining cards are ten-rich, and make powerful insurance bets at those times.
Doubling: Usually, when the player doubles he wants a ten. In ten-rich shoes, the player makes better double downs, getting closer to 21.
Blackjack: Both player and dealer will see more blackjacks, but the player gets paid 3 to 2, and the dealer does not.
Surrender: The alternative to surrendering is much worse in ten-rich shoes. If the alternative is hitting, the player is more likely to bust. If the player would otherwise stand, due to the high count, the dealer is still more likely to get a 10. While the counter will surrender more in high counts, the savings will be greater.
Splits: The player is usually splitting high cards and/or off of a weak dealer card. Either way, a ten-rich shoe helps the player get higher totals, and increases the probability of the dealer busting.
I'm working on an in-depth study of how these effects break down. The contribution to each factor depends on the rules, deck penetration, and bet spread. However, based on average conditions in a six-deck shoe, my initial results break down the benefits of counting as follows.
Why Card Counting Works
Player Option | Portion of Benefit |
---|---|
Stand | 40% |
Insurance | 34% |
Double | 9% |
Blackjack | 7% |
Surrender | 6% |
Split | 4% |
Card Counting Rules Meaning
The probability for insurance was taken from Don Schlesinger's 'Illustrious 18' list, as found in Blackjack Attack. The rest of the breakdown is mine.
To gauge the richness of the deck in good cards, the player will keep track of the cards the are already played. Strategies vary, but all assign a point value to each card. For example, the hi-lo count assigns a value of +1 to 2, 3, 4, 5, and 6, and -1 to tens and aces. Everything else is 0, or neutral. At the beginning of a deck or shoe, the count is 0. Then the counter constantly adds and subtracts from the count, according to the cards played. This running total is called the 'running count.' A positive count means that a disproportional number of small cards have already been played, which means that the deck is rich in large cards. To determine the 'true count,' divide the running count by the number of decks left to be played, or in some strategies, the number of half decks. This will tell you the relative richness of the deck in good cards.
The true count is used in two ways, to determine how much to bet and how to play your hand. Unless it is obvious, every situation has a line in which you should play one way if the count is above the line and another if below. For example, a 12 against a 6 may dictate that you stand if the true count is -1 or greater and hit if the true count is less than -1. The counter will also bet more when the true count is high, meaning the deck is rich in good cards.
A problem arises when it comes to treating aces. The player should bet more when the deck is rich in aces since they add to the probability of getting a blackjack. However, when it comes to playing your hand, the number of aces left is not nearly as important as the number of tens, so it is desirable, but not necessary, to distinguish between tens and aces. Some card counting strategies keep a side count of aces. In the Hi-Opt I and Revere Plus/Minus aces are counted separately and only considered when making the wager. This is a more accurate and powerful way to play than assigning a negative value to aces and not keeping a side count, as some strategies do. Yet, many people feel that for the beginner it is too confusing to keep two counts. A player is more likely to make mistakes keeping two counts and that costs money. The efficiency of a strategy that does not keep a side count of aces is only modestly less, but you likely will gain more from fewer mistakes made. Different experts fall in various places in the spectrum in terms of what to recommend for the beginner. The Zen Count takes the middle ground and gives aces a value of -1 and tens -2. Personally, I have tried both and would recommend against a count that requires a side count of aces to a person ready to take up card counting. The Uston Advanced Plus/Minus is a good strategy that does not involve an ace side count and can be found in the book Million Dollar Blackjack. How well you know a counting strategy is much more important than which strategy you know.
Legally speaking, the player may play blackjack any way he wants without cheating or using a computer, and the casinos may do anything from making conditions unfavorable to barring, in an effort to stop anyone who they deem has an advantage over the game. Much of the challenge of card counting is avoiding suspicion that you are anything but a normal non-counting player. The most obvious indication that somebody is counting is that they make a substantial increase in bet size after a lot of small cards leave the table. Although the greater the factor by which you can increase your bet the greater your odds of winning, more than doubling your last bet is a fast way to arouse 'heat'from the dealer and pit boss. Usually when casinos employees realize you are counting, they will either shuffle the cards whenever you increase your bet, essentially removing any advantage, or ask you to leave.
This is only scraping the surface of the subject of card counting. I suggest the following pages of mine.
