D'Alembert's roulette system

The principle of this method is quite simple. It can be easily adapted to the smallest portfolios with a relatively low-risk rate. If you decide to adopt this technique during your roulette sessions, be patient because it is very time-consuming.

An example would be more telling. First you need to decide on a unit bet that will serve as a basis.

For your first bet, you will place one unit. If this one turns out to be a winner, you will make your second bet with one unit. On the other hand, if your bet loses, you will have to bet two units for your second bet. If the second bet wins, you will reduce your bet to one unit for the next bet. On the other hand, if your bet loses, you will have to add another unit for your next bet and so on.

Hollandish's roulette system

Hollandish system is one of the riskiest techniques. It consists of looking for parity between two opposite chances on a losing progression. If this parity is obtained, this technique wins half a bet per move played.

Here's an example :

The aim of this technique is to erase the losses of the previous moves until parity is achieved between red and black. A small explanation for each move is necessary:

  1. Losing move - Increase the bet by one unit (1+1) for the next move

  2. Losing move - Keep the same bet for the next move (2) and try to recover the loss of the first move

  3. Winning move - The first move has been paid off, increase the bet by one unit (2+1) for the next move, and try to recover the loss of the second move.

  4. Losing move - Keep the same bet for the next move (3) and try to recover the loss on the second move

  5. Losing move - Keep the same bet for the next move (3) and try to recover the loss on the second move

  6. Winning move - The second move has been paid off, increase the bet by one unit (3+1) for the next move, and try to recover the loss of the fourth move

  7. Losing move - Keep the same bet (4) for the next move and try to recover the loss on the fourth move

  8. Winning move - The fourth move has been paid off, keep the same bet for the next move (4) and try to recover the loss of the fifth move

  9. Winning move - The fifth move has been repaid, increase the bet by one unit (4+1) for the next move, and try to recover the loss of the seventh move

  10. Winning move - The seventh move has been repaid and parity has been achieved. On this series of 10 moves, we got five red and five black with a profit of five units. This gives us a profit of half a bet per move played

Be careful, the much sought-after parity may take some time to achieve. When this parity has been reached, we advise you to start from scratch and not to continue with the same bets obtained at the time of parity.

Zographos' roulette strategy

This technique is one of the "safest" when it comes to roulette strategy. It is suitable for both small and large bankrolls. You don't have to increase your bet for every move you make, but you do have to keep it for every move you make.

Zographos' strategy is a technique that is played in 24 moves divided into eight sequences of three moves. Here is an example :

The first sequence is a so-called observation sequence :

  • 1st move : Black, not played

  • 2nd move : Black, not played

  • 3rd move : Red, not played

In the second sequence, you must repeat the previous sequence, this time betting your unit bet on each move :

  • 4th move : Black. Black plays, winning move

  • 5th move : Red. Black plays, losing move

  • 6th move : Red. Red played, winning move

After the firsts two sequences have passed, you will have to bet according to the dominant color by superimposing the moves of each sequence :

  • 7th move : Red. Dominant black played, losing move

  • 8th move : Black. No dominant, not played

  • 9th shot : Red. Dominant red played, winning move

For the fourth sequence, we take the same scheme of play but adding the scheme of the third sequence :

  • 10th move : Red. Dominant black played, losing move

  • 11th move : Black. Dominant black played, winning move

  • 12th move : Red. Dominant red played, winning move

Etc until you reach the 24 moves and the eighth sequence. When the 24 moves are reached, just start again from 0 with the first observation sequence. Some players, in an attempt to increase their winnings, add a unit of bet to each sequence. Of course, we do not advise this.

Wells' roulette system

This roulette technique is used with a table containing 9 bets: 1, 2, 3, 4, 5 (starting bet), 6, 7, 8, 9. The first bet (the chest bet) is therefore 5 betting units. Then, we will decrease the bet by one unit when we win and increase it by one unit when we lose, without ever exceeding the 9 betting units.

Here's an example :

In this example, we have arrived at the lowest bet of this technique. It is better to start from the beginning when we reach the bets at the ends of the table (1 or 9) and if it loses. This allows you to control your play and not lose everything.

Fibonacci's roulette system

As its name suggests, this roulette technique is based on the well-known "Fibonacci Suite". This mathematical sequence is as follows: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, ... For some, this sequence looks like a puzzle but it is not that complicated. In fact, each digit in the sequence is the sum of the two digits that precede it. If we take the fifth digit of the sequence, the 5, this one is the sum of the two previous digits, in this case, 3 and 2.

How are we going to apply this mathematical sequence to a roulette technique? Each number in the sequence represents the units of bet. We will start our game with one unit of bet, since the first digit in the sequence is 1. If this move wins, we don't change anything and start with the first number again.

However, if the move is lost, we add a straight number, which will give us a bet of 2 units for the next move. By dint of advancing in the continuation, at the moment when a move is winning, we will have to remove the two preceding figures.

An example will be easier to understand than a text :

Beware, if you decide to play with this roulette technique. As you can see, you can quickly lose track of it and go up to astronomical amounts. So you will have to start with small bets and do not greed directly from the first bet, otherwise you will break very quickly.

Labouchère's roulette system

Labouchère's system is a technique very similar to the Fibonacci's method. Indeed, we find a sequencing system but this time not based on a mathematical rule. You will have to choose a sequence of ascending numbers and add the ends together to get your first bet.

If the move is successful, the first and second digits of the sequence must be deleted and then a new bet must be made on the new ends. If the move loses, the sum of the ends is added at the end of the sequence. This gives us a new end to our sequence.

Here is an example to illustrate this with a defined sequence (1-2-3-4-5-6):

Be careful with this technique, it is as much or even more dangerous than the Fibonacci system. As you can see, you can very quickly generate big losses in just a few strokes. So if you decide to play this method, start your sequence with a low number and with a small sequence.

Martingale's roulette system

This roulette technique is without a doubt the best known of all. And it is quite normal, it does not require any intellectual and memorization skills.

The principle is simple, decide on a unit bet that will be the basis of your session. If your move wins, nothing changes, you can continue on this bet. On the other hand, if you lose, you will have to double your bet until your move is a winner.

Here's an example:

This technique is one of the most dangerous for your bankroll, if the seventh move had lost like the previous ones, there would have been a deficit of 127 betting units in just seven moves. And this, in the end, for a very low winning potential! Regardless of the level at which you will win your bet, the profit will always be one unit bet.

It is also important to remember that martingale is prohibited in land-based casinos and also online. Most of the time online casinos prohibit it in their conditions of use. If it is not forbidden online, you are however limited because each roulette table has a maximum bet. So if you get into the bets, it will be impossible for you to go beyond a certain limit.

Bidule's roulette techniques

As you know, Bidule loves roulette and develops crazy roulette techniques. There is no mathematical research behind his techniques, he just tries to play with extreme volatility so that he can blow up his balance and thus have a big casino session.


This technique has accompanied Bidule since its beginnings in the world of online casinos. There is no particular pattern for the value of the bets, but a pattern for the positioning of the bets.

Bidule bets on all possible bets between 0 and 9, this includes full numbers, squares, and straddles. In the beginning, he also played the sixains and the dozens to increase his potential winnings, but in time he decided to remove these bets.

In this cluster, three numbers will be boosted: 3, 5 and 7.

Here is a video so that you can make a judgment on this "technique":

Taour's technique

As its name suggests, this technique was invented by the Taour streamer. This technique is, as Taour says, a drawing that constantly evolves to give a beautiful shape to the numbers.

Taour is a friend of Bidule who doesn't hesitate to come and see him live and encourage him to play his famous technique. Judge for yourself:

Triple 7

If you're a regular on Bidule's streams, you're probably aware that he loves the number 7! And it's understandable, 7 is a beautiful number.

This technique consists of betting on three numbers with 7: 7, 17 and 27.


Here is a technique created by Bidule a short time ago. This technique consists of playing the full bets from 4 to 9 as well as the two squares of this sequence. There is no particular value to emphasize, but the idea is to put the triple or quadruple of the full bets in a square.

Here is a video, which will allow you to better visualize the thing:


As stated in the introduction, this article is for information purposes. All these techniques could be perfect, but there is one element that takes them ALL apart! And yes, of course we want to talk about that little factor that gives the casino the edge: 0.

This 0 gives the casino a slight advantage and lowers the probability of winning to 48,64 % on a win ratio of 1 to 1 (instead of 50 % if the 0 did not exist). All these techniques have been developed without taking into account the number 0.

We, therefore, advise you to be VERY CAREFUL if you decide to play these mathematical techniques. To test them, we have set up on our site the roulette game.
