Here you can find out how to use it, why it works and what its drawbacks are. As you sit down at the table, or when the deck is shuffled you will have a mental count of zero in your head. Then as cards are dealt out, no matter whose hand they belong to they are given a value which is added to the count. These values are:. While the math here is simple, you are either adding 4 or subtracting 9, you will need to be quick with your calculations especially on a full table with lots of cards on show.
To begin with you should start with your minimum bet as the count goes positive, the higher it gets the more you should increase your wagers. When the count starts to return to zero or go negative you should lower your bets and return to betting minimum.
In the 10 Count system you are basically keeping track of the odds of receiving a value card. The higher the count goes the greater chance you have of seeing a When you are playing basic strategy and flat betting the house edge will remain constant across the session. As basic strategy assumes the next card will always be a 10, it will become truer with more 10s available to come.
By betting higher in these spots you increase your profits when the game is most favorable to you. The main limitation of this method is it is only useful for single deck games, which are rare to find now. Many others exist. The primary goal of a card counting system is to assign point values to each card that roughly correlate to the card's "effect of removal" or EOR that is, the effect a single card has on the house advantage once removed from play , thus enabling the player to gauge the house advantage based on the composition of cards still to be dealt.
Larger ratios between point values can better correlate to actual EOR, but add complexity to the system. Counting systems may be referred to as "level 1", "level 2", etc. The ideal system is a system that is usable by the player and offers the highest average dollar return per period of time when dealt at a fixed rate.
With this in mind, systems aim to achieve a balance of efficiency in three categories: . Some strategies count the ace ace-reckoned strategies and some do not ace-neutral strategies. Including aces in the count improves betting correlation since the ace is the most valuable card in the deck for betting purposes.
However, since the ace can either be counted as one or eleven, including an ace in the count decreases the accuracy of playing efficiency. Since PE is more important in single- and double-deck games, and BC is more important in shoe games, counting the ace is more important in shoe games. One way to deal with such tradeoffs is to ignore the ace to yield higher PE while keeping a side count which is used to detect an additional change in EV which the player will use to detect additional betting opportunities that ordinarily would not be indicated by the primary card counting system.
The most common side counted card is the ace since it is the most important card in terms of achieving a balance of BC and PE. Since there is the potential to create an overtaxing demand on the human mind while using a card counting system another important design consideration is the ease of use.
The Running count is the running total of each card's assigned value. When using a Balanced count such as the Hi-Lo system , the Running count is converted into a "True count," which takes into consideration the number of decks used. With Hi-Lo, the True count is essentially the Running count divided by the number of decks that have not yet been dealt; this can be calculated by division or approximated with an average card count per round times the number of rounds dealt.
However, many variations of the True count calculation exist. Back-counting, also known as "Wonging," consists of standing behind a blackjack table that other players are playing on, and counting the cards as they are dealt with. Stanford Wong first proposed the idea of back-counting, and the term "Wong" comes from his pen name.
The player will enter or "Wong in" to the game when the count reaches a point at which the player has an advantage. The player may then raise their bets as their advantage increases, or lower their bets as their advantage goes down. Some back-counters prefer to flat-bet, and only bet the same amount once they have entered the game. Some players will stay at the table until the game is shuffled, or they may "Wong out" or leave when the count reaches a level at which they no longer have an advantage.
Back-counting is generally done on shoe games, of 4, 6, or 8 decks, although it can be done on pitch games of 1 or 2 decks. The reason for this is that the count is more stable in a shoe game, so a player will be less likely to sit down for one or two hands and then have to get up.
In addition, many casinos do not allow "mid-shoe entry" in single or double deck games which makes Wonging impossible. Another reason is that many casinos exhibit more effort to thwart card counters on their pitch games than on their shoe games, as a counter has a smaller advantage on an average shoe game than in a pitch game.
Back-counting is different from traditional card-counting, in that the player does not play every hand they see. This offers several advantages. For one, the player does not play hands at which they do not have a statistical advantage. This increases the total advantage of the player. Another advantage is that the player does not have to change their bet size as much, or at all if they choose.
Large variations in bet size are one way that casinos detect card counters, and this is eliminated with back-counting. There are several disadvantages to back-counting. One is that the player frequently does not stay at the table long enough to earn comps from the casino. Another disadvantage is that some players may become irritated with players who enter in the middle of a game, and superstitiously believe that this interrupts the "flow" of the cards.
Their resentment may not merely be superstition, though, as this practice will negatively impact the other players at the table, because with one fewer player at the table when the card composition becomes unfavorable, the other players will play through more hands under those conditions as they will use up fewer cards per hand, and similarly, they will play fewer hands in the rest of the card shoe if the advantage player slips in during the middle of the shoe when the cards become favorable because, with one more player, more of those favorable cards will be used up per hand.
This negatively impacts the other players, whether they are counting cards or not. Lastly, a player who hops in and out of games may attract unwanted attention from casino personnel and may be detected as a card-counter. While a single player can maintain their own advantage with back-counting, card counting is most often used by teams of players to maximize their advantage. In such a team, some players called "spotters" will sit at a table and play the game at the table minimum, while keeping a count basically doing the back "counting".
When the count is significantly high, the spotter will discreetly signal another player, known as a "big player," that the count is high the table is "hot". The big player will then "Wong in" and wager vastly higher sums up to the table maximum while the count is high.
When the count "cools off" or the shoe is shuffled resetting the count , the big player will "Wong out" and look for other counters who are signaling a high count. This was the system used by the MIT Blackjack Team , whose story was in turn the inspiration for the Canadian movie The Last Casino which was later re-made into the Hollywood version The main advantage of group play is that the team can count several tables while a single back-counting player can usually only track one table.
This allows big players to move from table to table, maintaining the high-count advantage without being out of action very long. It also allows redundancy while the big player is seated as both the counter and big player can keep the count as in the movie 21 , the spotter can communicate the count to the big player discreetly as they sit down. The disadvantages include requiring multiple spotters who can keep an accurate count, splitting the "take" among all members of the team, requiring spotters to play a table regardless of the count using only basic strategy, these players will lose money long-term , and requiring signals, which can alert pit bosses.
A simple variation removes the loss of having spotters play; the spotters simply watch the table instead of playing and signal big players to Wong in and out as normal. The disadvantages of this variation are reduced ability of the spotter and big player to communicate, reduced comps as the spotters are not sitting down, and vastly increased suspicion, as blackjack is not generally considered a spectator sport in casinos except among those actually playing unlike craps , roulette and wheels of fortune which have larger displays and so tend to attract more spectators.
A mathematical principle called the Kelly criterion indicates that bet increases should be proportional to the player advantage. In practice, this means that the higher the count, the more a player should bet on each hand in order to take advantage of the player's edge. Using this principle, a card counter may elect to vary their bet size in proportion to the advantage dictated by a count creating what is called a "Bet ramp" according to the principles of the Kelly criterion.
A bet ramp is a betting plan with a specific bet size tied to each true count value in such a way that the player is betting proportionally to the player advantage with aim to maximize overall bankroll growth. Taken to its ultimate conclusion, the Kelly criterion would demand that a player not bet anything at all when the deck does not offer a positive expectation; the "Wonging" strategy described above implements this. Historically, blackjack played with a perfect basic strategy offered a house edge of less than 0.
Advantages of up to 2. The variance in blackjack is high, so generating a sizable profit can take hundreds of hours of play. Under one set of circumstances, a player with a unit bet spread with only one-deck cut off of a six-deck game will enjoy an advantage of as much as 1.
Instead, it comes from the increased probability of blackjacks, increased gain and benefits from doubling, splitting, and surrender, and the insurance side bet, which becomes profitable at high counts. A range of card counting devices are available but are deemed to be illegal in most U. Card counting with the mind is legal, although casinos in the US reserve the right to remove anyone they suspect of using the technique.
Card counting is not illegal under British law, nor is it under federal, state, or local laws in the United States provided that no external card counting device or person assists the player in counting cards. Still, casinos object to the practice, and try to prevent it,  banning players believed to be counters.
In their pursuit to identify card counters, casinos sometimes misidentify and ban players suspected of counting cards even if they do not. In , Ken Uston , a Blackjack Hall of Fame inductee, filed a lawsuit against an Atlantic City casino, claiming that casinos did not have the right to ban skilled players. The New Jersey Supreme Court agreed,  ruling that "the state's control of Atlantic City's casinos is so complete that only the New Jersey Casino Control Commission has the power to make rules to exclude skillful players.
As they are unable to ban counters even when identified, Atlantic City casinos have increased the use of countermeasures. Macau , the gambling capital of the world and the only legal gambling location in China,  does not technically prohibit card counting but casinos reserve the right to expel or ban any customers, as is the case in the US and Britain. Monitoring player behavior to assist with detecting the card counters falls into the hands of the on-floor casino personnel " pit bosses " and casino-surveillance personnel, who may use video surveillance "the eye in the sky " as well as computer analysis, to try to spot playing behavior indicative of card counting.
Early counter-strategies featured the dealers learning to count the cards themselves to recognize the patterns in the players. Many casino chains keep databases of players that they consider undesirable. For successful card counters, therefore, skill at "cover" behavior, to hide counting and avoid "drawing heat" and possibly being barred, may be just as important as playing skill.
Detection of card counters will be confirmed after a player is first suspected of counting cards; when seeking card counters, casino employees, whatever their position, could be alerted by many things that are most common when related to card counting but not common for other players.
These include:   . Card counters may make unique playing strategy deviations not normally used by non-counters. Extremely aggressive plays such as splitting tens and doubling soft 19 and 20 are often called out to the pit to notify them because they are telltale signs of not only card counters but hole carding. Several semi-automated systems have been designed to aid the detection of card counters. The MindPlay system now discontinued scanned card values as the cards we're dealt.
The Shuffle Master Intelligent Shoe system also scans card values as cards exit the shoe. Software called Bloodhound and Protec 21  allows voice input of card and bet values, in an attempt to determine the player edge. A more recent innovation is the use of RFID signatures embedded within the casino chips so that the table can automatically track bet amounts.
Automated card-reading technology has known abuse potential in that it can be used to simplify the practice of preferential shuffling —having the dealer reshuffle the cards whenever the odds favor the players. To comply with licensing regulations, some blackjack protection systems have been designed to delay access to real-time data on remaining cards in the shoe. With card values, play decisions, and bet decisions conveniently accessible, the casino can analyze bet variation, play accuracy, and play variation.
Bet variation. The simplest way a card counter makes money is to bet more when they have an edge. While playing back the tapes of a recent session of play, the software can generate a scatter plot of the amount bet versus the count at the time the bet was made and find the trendline that best fits the scattered points.
If the player is not counting cards, there will be no trend; their bet variation and the count variation will not consistently correlate. If the player is counting and varying bets according to the count, there will be a trend whose slope reflects the player's average edge from this technique.
Play variation. When card counters vary from basic strategy, they do so in response to the count, to gain an additional edge. The software can verify whether there is a pattern to play variation. Of particular interest is whether the player sometimes when the count is positive takes insurance and stands on 16 versus a dealer 10, but plays differently when the count is negative. Casinos have spent a great amount of effort and money in trying to thwart card counters.
Countermeasures used to prevent card counters from profiting at blackjack include:    . Some jurisdictions e. Nevada have few legal restrictions placed on these countermeasures. Other jurisdictions such as New Jersey limit the countermeasures a casino can take against skilled players.

You divide your running count by the number of decks in the shoe to determine the true count. However, many variations of the True count calculation exist. Unlike in some of the other, easier card counting systems, aces have a value of 0 in the running count using Omega 2. Most people can memorize all the rules via a chart in a couple of hours at most.|

Although nothing is set in stone, there is definitely some type of benefit when you play using strategic moves and proper bankroll management. One of the most popular strategies used in blackjack is card counting. It allows players to predict what can the upcoming cards be. This way it is possible to guess whether the following cards will be beneficial or not for the game. Using the right card counting technique can allow gambling enthusiasts to take the right decision and tip the scales in their favour.
Card counting system can actually improve the gaming skills of players and they can benefit from understanding the pattern that each game of blackjack is using. Another benefit of using card counting is that it helps to eliminate the cards that have already been dealt. The cards that have been removed from the deck influence the house edge in a way and it is good to know how the outcome of the game can be affected by each card that has been drawn from the deck.
Using card counting strategy basically allows players to understand better the dynamics of the game. This way they will be able to make easier decisions about their moves and bets. This is very important as it gives players a much better chance of actually sweeping good wins since they will be able to last longer in the game. There is also a basic blackjack strategy that can be used by fans of the game of Although everyone who is at least a little familiar with blackjack will know that hitting on 11 is the logical move, there are quite a lot of other situations when it can be pretty difficult to determine the move that should be done.
By utilising the basic strategy, newbies can quickly become seasoned blackjack players. If you look up for a basic blackjack strategy, you will come across charts with all possible hands that you may be holding and the moves you are advised to make under different circumstances. Of course, depending on the blackjack variation that you are playing, it is possible that the strategy might change.
This is why it is recommended to find the system that works for the version you are about to play and bet real money on. Even though you can be certain that you will always win by using a basic strategy or a card counting system, it is much better to have some plan when you sit at the blackjack table. Otherwise, you can simply consider your gambling as a waste of time and money. The blackjack system you might use really depends on the type of game that you are playing.
Whether you prefer to play at a land-based or an online casino also affects the type of strategy you might use. Although card counting is quite popular, it is quite impossible to use it at virtual casinos since most online variations of the game shuffle the deck after every hand that is being played. This makes the use of this technique useless. This being said, interactive players can easily have the table with the basic strategy in front of them and use it to decide their moves.
When you think of blackjack, you can say that the decisions made by the player determine a big part of the outcome. This is why there has been a mathematical strategy that can be used during the game of It provides a chance of improving the odds of winnings. This strategy, however, must be used every time you play. This way you will be able to tilt the scales in your favour and benefit from the best possible odds. What is known as a basic strategy is a chart that shows you whether you are advised to hit, stand , double down or split under certain circumstances.
On the chart, you will notice that there are sections that show all the possible hands you might be dealt. Although many rooky blackjack players prefer to follow their instincts and play cautiously due to the fear of going bust, using the basic strategy can significantly change their gambling experience. By relying on the chart, players can actually improve their chances in the game by making the optimal decision.
Although in blackjack, just like in any other casino game, the house has an advantage. However, the game of 21 is the perfect casino entertainment for many players as it has one of the lowest house edges. Using basic strategy can even make your chances of winning better. There is definitely a benefit when blackjack players use basic strategy. For instance, when players use this technique, the house edge is lowered to 0. As you can see this is definitely a worse scenario for the player and much bigger advantage for the house.
There is hardly anyone who has not heard about card counting, especially if they are interested in gambling. This advanced strategy is known to give players a big advantage. This is why although card counting is not illegal, many land-based casinos would kick out players who use this tactic. Card counting is a strategy where you have to use your memory in order to keep track of which cards were dealt and which ones can be the upcoming cards in the next deal. This way players would be able to make better and easier decisions when it comes to their betting.
Since in the majority of brick-and-mortar casinos the cards are dealt from a shoe, it can be predicted which cards have remained in the deck and this way the moves of players can be adjusted to the upcoming possibilities. Thanks to the card counting tactic, players can get a general idea which cards have remained in the shoe after the first deal. However, the fact that many blackjack tables use several decks requires players to divide their current count by the number of remaining decks.
This way they will get what is known as a true count. Although card counting system was developed by mathematicians, it is a common misconception that only players with extraordinary mathematical skills and photographic memory can apply it. What is difficult to be learned, however, is hiding your skills from the dealers at land-based casinos. This might be an issue as many gambling facilities do not accept players who use card counting.
Although there are different variations of blackjack, the main of the classic one is to get a score of 21 without exceeding it. In most cases, the deck is shuffled only once before the game begins. Players who use card counting will be able to keep track of the cards that have already been drawn and this way they will be able to deduce which cards have remained in the deck.
This way blackjack enthusiasts will make a decision whether they would bet high or low. Let us assume that during the game only low-valued cards have been dealt. This would mean that there is a big chance that the upcoming cards may be Royals. This would be a great time to make a high bet. Having been dealt only high-value cards would imply that it is the best if you make low bets and hit without worrying about going to bust. The essential thing about card counting is that the odds of the game change with every card that has been dealt.
Usually, the dealer puts the hands that have been played in a discard tray. Only the remaining cards in the deck are used during the next deal. Usually, the card counting system revolves around estimating the possibility of drawing a valued card from the remaining ones in the deck. The easiest way to count cards is by assigning them with a tag, i.
Since card counting is a strategy used by many blackjack players, it is no surprise that nowadays players can utilise various systems of counting. For those who are excited that test the card counting technique, there are several variations they can choose from. Probably the most widely known card counting system is the Hi-Lo High-Low one.
Its popularity can be contributed to the fact that it is considered a very reliable system. What is more, this method of card counting is very easy to comprehend. The Hi-Lo system uses the so-called tagging technique which gives each card of the deck either a positive, a neutral or a negative value.
Thanks to this system of counting, players can adjust their bets easily. This system of card counting is another easy-to-use technique while playing blackjack. The method of assigning cards with positive, neutral and negative values is yet again used in Red Seven. However, there is a slight difference when it comes to the 7s of the deck. The black seven is tagged as 0 and the counting principle for the rest of the cards is the same as the one in Hi-Lo. This system of card counting has more to offer than simply an intricate name.
This method is quite simplified which gives inexperienced players the opportunity to use it. The reason why this system is so easy to be used by players is that they do not have to count almost half of the cards in the deck as they are irrelevant to the process of predicting the outcome.
Those who use this method would have to give a new value only to the face cards and the ones from 4 to 6. The rest of the cards are counted as 0. This is done so that the system becomes unbalanced which is a way of avoiding the conversion of the running count into a real count. The KISS 2 counting method adds a few other cards you should keep in mind while playing.
Face cards and 10s are valued as -1 and the rest of the cards are tagged as 0. Last but not least is the KISS 3 variation of this card counting system. It resembles the previous two but is optimized to provide the best odds and to help blackjack players make the best decision. Yet again, players give cards either positive, negative or neutral values.
This way they can determine what can be the possible outcome of the game and make the best possible bets. The face cards, 10s and the Aces are counted as -1 and the rest of the deck is counted as neutral. As you can see, the K-O counting system is also pretty easy to be used in the game and even inexperienced players would have no issue utilising it. Instead, there are a number of card counting systems that use whole numbers that remain constant throughout the counting process to provide an estimation of the advantage.
The accuracy of their estimation often comes at the cost of increased complexity, hence difficulty to learn and implement. Here are some of the more popular card counting systems. To give credit where credit is due, this system was developed by Stanford Wong, a prolific author who has authored volumes on almost every casino game. Arguably, this is closer to the actual mathematical weight of the cards, as the seven and nine are not completely neutral—but at the same time, the effect of either is less than a third of a percent.
Legendary blackjack professional Ken Uston pioneered this system, which is largely identical to the high-low count, except that deuces are treated as neutral and sevens as dealer-favourable. Weighed against the mathematical impact of the cards, both assumptions are mistakes, but they more or less cancel each other.
This system is the first of two deviations on the high-low system popularized by Lance Humble and Carl Cooper. Though this would seem to defy common sense, it works out to be a reliable system in computer simulations.
