Basic Tips and Tricks for Blackjack

Before you even think about learning one of the special systems, you should definitely familiarize yourself with the basic rules and then learn the perfect basic blackjack strategy. Only when you have mastered these two components does it make sense to add a more advanced strategy. If you didn't, it would be like buying decorative items for a house that doesn't even have the foundation walls in place. So always one after the other.

Basic rules for playing with the 21

Old hands who are sufficiently familiar with the basic rules and technical terms are welcome to skip this section. For everyone else, however, there is an introduction to the most famous card game in the world.

Procedure and aim of the game

Blackjack is played against the bank, i.e. against the dealer. Before you start, place your bet in the so-called “box”. When all players have placed their bets, the cards are dealt. Each player is given 2 playing cards “face up”, which means that the card values ​​are visible to everyone. In “Hole Card Games” the dealer is dealt his second card face down and is allowed to look at it. Most of the time, however, the game is played in such a way that the dealer only receives his second card at the end.

The usual sets of 52 cards are used and the number of decks is usually between 1 and 6. Everyone now has If you have two cards, they can take their actions clockwise. The aim of the game is to get as close as possible to 21 points without overbidding that number. If you have a higher number of points than the dealer at the end of the round, the hand is considered to have been won.

The card values ​​in Blackjack

  • The ace is the best card in the game because it is the most likely to get to 21. It counts as 1 or 11 points, depending on the needs of the player.
  • All face cards i.e. jack, queen and king count 10 points.
  • All cards with numbers count their respective value.


The first option you have, when it is your turn, is not to ask for another card. This means that you are already satisfied with your current 2 cards. If this is the case, one speaks of stand. To do this, click on the corresponding button in the online casino, and you can show it live with a horizontal hand movement. A good example of this would be if you have 20 points and anything but an ace would cause you to lose.


Would you like to ask for another card since you believe yours current score is not enough to win the hand, then that means hit. Online there is the necessary button and live just tap on the table.


This action turns the original hand into 2 new hands . This is only possible if both cards have the same value. If you so choose, the dealer will split the two cards and you will have to place another bet. If you split aces, you can only apply for one more card.

Double Down

This is often only allowed if the value of your hand is 9, 10 or 11 points. If you only apply for one more card, then double your bet.


Neither popular nor useful, but quite possible. If you lose half your stake, you have the option of simply giving up at any time. You then wait until the round is over and play the next hand again.

The deal

When all players have taken their actions, the dealer draws his second card. If he has 17 points or more, he says stood. With 16 points he must draw another card. The winner has now been determined. If you are one of the lucky ones, you will get double the stake. With a blackjack, i.e. an ace and 10 points, there is even more.

The perfect blackjack strategy

In contrast to many other games of chance, blackjack actually has the perfect way of playing . The foundation stone was laid for this as early as 1956. At that time 4 mathematicians published an article with the title: Optimum Strategy in Blackjack. You can imagine that that caused a lot of attention and, above all, for a lot of discussion. A book that resulted from this became extremely well known.

In Beat the Dealer declared Ed Thorpe In simple terms, how to reduce the house edge in blackjack to a fraction of a percent with the perfect style of play. This tactic has not changed until 2021 and you will now be given a table. With this blackjack table you always know what to do. Stick to it 100% and you will automatically master the perfect strategy.

The High Low System

First of all, if if it is possible to use this system, it actually gives you a mathematical advantage over the bank. You read that right, it will make you a theoretical winner, provided you master the perfect basic strategy. This technique, also known as card counting, led in the past to one or the other stealing a fortune from casinos, and is also the basis of the Hollywood film “21”. Unfortunately, the providers of blackjack have reacted in the meantime and are trying by all means to prevent successful counting and the winnings that come with it

Wie funktioniert das Blackjack System Kartenzählen

Before we reveal the specific procedure to you, here is a description of how it works for a better understanding. Since all cards are dealt face-up in blackjack, they are logically visible to all players or to the people standing next to them. So if you pay close attention, you can tell what is left towards the end of the deck of cards. Due to this special feature and the correct betting behavior, the house advantage can be reversed. If you bet low all the time, and only bet high towards the end of the stack, and only if there is a good chance of winning, you have a very good chance of making high profits.

For this reason, casinos often bet Up to 6 decks of cards and swap them before the expiry within the blackjack tables. If it is possible to count to the end, you have to be careful that you are not immediately exposed as an advantage player due to the characteristic betting behavior. Casinos have house rights and can simply exclude you from the game.

How do you count?

As the name suggests, the high-low system differentiates between high and low cards. It is divided into 3 groups:

  1. The cards 10, Jack, Queen, King and Ace are assigned the value -1.
  2. The 7, 8 and 9 are assigned the value 0.
  3. The lower cards, i.e. 2 to 6, are given the value +1.

Ideally, you start with a new deck of cards with the value 0 and change it accordingly with each card you see . If you have a positive number towards the end of the stack, the odds are good that you will win. Then you should bet a lot. The higher the value, the more likely it is. However, there is no guarantee.

In order not to attract attention so quickly, the professionals in the Live Casino work as a team here, by the way. One player sits at the table and consistently bets the minimum. When the odds are good, he gives a secret signal. Then the second player comes and makes a high roller bet “quite randomly” at the right time.

Online card counting

Most people think that card counting is generally not possible in online casinos. In fact, you can't say that across the board. The software manufacturers must guarantee an insight into how their games work. If, for example, classic blackjack is offered, the algorithm must also simulate the course of this game one-to-one. It can be assumed, however, that after each hand it is simply shuffled or counting is otherwise difficult. After all, it is hardly possible to use the technology successfully in the live area, as casinos fight this with all their means.

The Kelly formula as a blackjack strategy

This mathematical formula, which one too Kelly criterion is called, goes to the scientist John Larry Kelly Jr. back. It is used to maximize profits in bets with positive profit expectations without ever losing the entire capital. Even if the house advantage is very small in blackjack with perfect strategy, it is still there.

The only moment when you as a player have a positive expected value is when you are successfully counting cards. The Kelly criterion can only be applied in this case. With the formula you calculate the so-called Kelly share and this in turn indicates how much of your total playing capital you should bet on one hand. The higher the probability of winning, the bigger your bet can turn out.

Kelly share = chance / win rate

Your win rate in blackjack is normally 2, as the stake is doubled if you win. Let's assume that by successfully counting cards, your chance of winning is 60%, i.e. 0.6 and your total playing capital is € 1000. The Kelly formula in this case says that you should bet 0.6 / 2, i.e. 0.3 of your capital. The correct stake in this case would be € 300.

1, 3, 2, 6 Betting System

This is a very popular system for betting where the stake is doubled. For this simple reason it is also often used when playing with the 21st. Here, a series of a maximum of 4 wins is considered. Once these have been reached, you start all over again. The exact procedure is already hidden in the name of the system. At the beginning you determine the first setting size. This should be based on your total capital for the blackjack session.

Let's take € 5 as an example. On the first hand you play, you bet € 5 so 1 and if you win you have € 10. You now add another € 5 to the stake and thus have € 15 so 3. If you win this hand too, you have € 30, of which you put € 20 in your pocket, so with a stake of € 10 you end up with 2. If you win, add the € 20 from the 2nd hand to the € 10 and thus bet € 30 6 pieces. If lost or after a successful 4. The whole bet then starts all over again.

Progressive betting systems for blackjack

A whole range of techniques can be summarized under this generic term, which provide for an increase in the bet if the stake is lost. If you take these tips into account, you will often have a winning streak, but you will not be able to outsmart the math of the game. Most progressive blackjack strategies have many moderate wins and one potentially large loss. Nevertheless, there are a large number of players who swear by these systems and make a profit with them over a long period of time. In the following we present the most famous of them.

Martingales as a blackjack tactic

This system, which has been known since the 18th century, is better known for its use in roulette. One of the best-known users of this strategy was Giacomo Casanova. In his memoirs he describes his initial successes and his final total loss with the system. For this reason it is sometimes also called Martingale de Casanova.

How it works is quickly explained. You start with a stake of, for example, € 10. In the event of a loss, it is doubled until there is a profit. Then start all over again. The system is based on the fact that there is no way you can always lose whatever is true. However, it fails due to one of the following factors:

  1. Maximum bet on the part of Online casino
  2. Player's financial resources

Could that Player actually doubles their bets indefinitely, the system would really work. However, the casino generally sets a maximum bet to prevent this. In any case, many players underestimate how quickly the bet increases by doubling. An example: If you start with a stake of € 10, you will have staked € 40,950 after 12 games. However, the table maximum is usually reached long beforehand or you run out of money.

It is true that the probability of winning with Martingale is very high. Here's an example as well: Suppose you could afford to double the stake 12 times and the casino would allow you to do so. Then you would have a 99.9664% chance of winning. That is, of course, an impressive number. The house edge remains the same in the end.

The Fibonacci Blackjack System

Perhaps one or the other of you has heard of the Fibonacci system or the Fibonacci sequence. Before we reveal how this highly interesting mathematical concept fits into our series of blackjack tips, here is a basic explanation.

The Fibonacci sequence describes an infinite sequence of numbers, where each number is the sum of the 2 preceding numbers:

1, 1, 2, 3, 5, 8, 13, 21, 34…

Fascinatingly, many processes in nature follow this mathematical basis. An example of this is the increase in a rabbit population and the growth of many plants. The Fibonacci numbers can be found, among other things, in:

  • Fruit heads of sunflowers
  • Fruit heads of pineapples
  • Artichoke flowers
  • Baskets of silver thistle
  • In the ancestral line of honeybees

So it is a mystical mathematical basis which apparently determines biological processes in our world. But the series of numbers is also used outside of biology. For example, professional traders have been working with it for a long time and thus determine changes in the share price. Some refer to this as humbug, but others swear by it and trust large sums of money on it. But how exactly can this be included in the Black Jack tips?

Fibonacci way of setting blackjack

The specific procedure is very simple. They simply ensure that each bet compensates for the loss of the two previous bets. For this you use the Fibonacci number series. So if you bet € 10 and lose, you bet € 10 again. If lost, then € 20 and if lost again then € 30. If you win, you return to the original bet.

At first, this approach is a bit reminiscent of Martingale, but it is very different. After all, it does not double stakes. With the Fibonacci method in blackjack you ensure a low variance without driving up the stakes so quickly. However, you don't change the house edge.

Blackjack tricks with d’Alembert

The French mathematician, physicist and philosopher Jean-Baptiste le Rond d’Alembert is known for numerous scientific achievements. Many of his math concepts are highly complicated differential equations. However, when the d'Alembert concept is mentioned in relation to gambling, the process is very simple. Let's look at the following series of numbers:

1, 2, 3, 4, 5, 6, 7, 8, 9…

As you can see for yourself, this is simply a continuous one Sequence. In other words, the increase is linear. If you use the d'Alembert concept in blackjack, here is what you are doing. You start with a bet of 1 piece, if you lose you then bet 2 pieces, if you lose again then 3 pieces and so on. Initially, the procedure is similar to the Fibonacci system, but the progression is much flatter towards later. If you win, simply move one step to the left in the sequence.

With d’Alembert, the stakes do not increase as quickly as with Martingale and Fibonacci, which means that the table limits are not reached as quickly. However, you may already be guessing that the provider's original house edge will continue to exist with this.

Blackjack strategies at a glance

The attentive reader has probably already noticed the different techniques they have all one thing in common. They ultimately fail to change the house edge of blackjack in the player's favor. The only exception is the high-low technology. If this can be used successfully, the already tiny house advantage shifts significantly to the side of the player. There is never a 100% chance of winning, but the chances are very good to make a hefty profit and thus outsmart the house. If the high-low technology is then combined with the Kelly component, an overall concept is created that shakes every casino to its foundations.

Casinos and online casinos have domiciliary rights

The only problem is that no provider is forced to let you play with them. So if you go to the casino in Bregenz and count cards there successfully, you can assume that sooner or later you will be banned from the house. Since the casinos help each other in this area and exchange data in order to protect themselves from so-called advantage players, it is even possible that you will then be considered an uninvited guest throughout Germany. The greatest caution and a very considered approach are required here.

The same applies to online blackjack tricks. It is here that programs save your every action and the pattern of an advantage player is quickly noticed. Here, too, there is a risk of exclusion from the platform in an emergency. So if you intend to use the appropriate techniques to cream off, you should be very careful with it. Finally, online there is also the fact that your money is not in your hands in the form of chips, but in digital form with your provider. If he has integrated a corresponding clause in the terms and conditions that prohibits certain technologies, you run the risk of your credit being withheld.


We hope we were able to give you an insightful insight in the world of blackjack strategies and show you which tricks bring a real mathematical advantage. You should also now be able to see that while progressive betting systems often produce a long winning streak, they do not change the house edge in any way. Ultimately, gambling should not be seen as a source of income, but for what it is. Entertainment with a little thrill and the chance to win. Finally, we would like to note that none of the blackjack tips and tricks presented here are illegal, including card counting.
