How to play Roulette Systems?

Roulette Systems

Last week we reported on the payout odds of the different betting options on the tableau. In this blog we talk about game philosophies and systems.
As old as gambling are systems with which the player “always, most certainly, one hundred and ten percent …”must “win”.

A fundamental distinction is made between mathematical and physical systems. Although no system that is played without prohibited manipulations can defeat the bank advantage. Unfortunately, time and again players fall for cheats who pretend to have developed functioning systems. They try to sell them in the form of books or e-books, which only brings profit to the providers.

Mathematical Systems

Martingale games

The stake in case of loss increases, these systems are among the oldest and are also used in other games of chance such as Baccarat (see previous blogs on

The Martingale classique, i.e. the “classic” Marginal System, at the same time the simplest, I would like to explain briefly, the others are only mentioned.
The player starts his “attack” (this is how system players call their betting series) with a piece. Mostly “simple chances” (see blog from April 3, 2020) are played, i.e. fields where the payout ratio is one to one. We take the minimum stake in VIP Roulette at live, i.e. CHF 2,– and bet e.g. on all even numbers.

If an odd number is thrown, the player doubles his bet to Even, i.e. the bet is now already CHF 4. If a further odd number is thrown, the system prescribes a bet of CHF 8 on Even. The idea behind this system is that at some point Even must come and the winnings of the first bet go into the system player’s pocket. (If an even number wins at CHF 8 in our example, the winnings are CHF 8, the losses were CHF 2, and CHF 4, i.e. CHF 6, which equals a win of CHF 2).

So why does this system not work also theoretically?

The stakes very quickly reach undreamt-of heights. At 15 times the stake would have to be a nice CHF 32768, so the total stake in this “attack” is already CHF 65534. (If you have any questions in the blog, e.g.: how do I come up with this number, just write.) Only a few more losses and the sum is almost impossible to raise. But even with theoretically unlimited financial means, every legal casino, like also has upper table limits – in the case of VIP roulette CHF 5000. Thus this attack would not continue after the twelfth loss.

The psychological component must not be disregarded either. With each attack, only one “piece” can be won, i.e. the basic stake. If, for example, the betting chance only comes up after the tenth time. The win is CHF 2, but CHF 1022 has already been bet before the win. A very bad relationship between stake and win and a lot of nerves that are strained for little money!

Other important marginal systems:

  • the Progression d’Alembert
  • the Fitzroy system
  • the Montant et démontant system
  • Montante Americaine
  • the Montante Hollandaise

Systems with constant inserts

These systems are based on the very common superstition that if, for example, a red number is thrown 5 times in a row, black has a higher probability of winning on the next roll. Which is why many system players do not launch an attack until after a few red numbers on black. But on every roll – regardless of the numbers thrown before – the chances are the same. 18 red numbers against 18 black and the green zero.

Many players therefore meticulously record the sequence of numbers both in the online casino and at the roulette table in the casino. For a long time, casinos have been selling so-called permanents, from which the buyers hope to gain an advantage in the game. On the basis of these permanences, many providers of systems also “prove” the infallibility of these systems. However, it is easy to use only the number series that fit the system.
The followers of this strategy only bet when they believe a possible use is preferred over others and play these possibilities.

Physical systems

Boiler fault

This system tries to take advantage of the “perfect” shape of the boiler which can never be achieved. This means that not all 37 numbers in the boiler have the same probability of the ball coming to rest in the compartment in question. The aim of the players is to find out the preferred numbers and then to put this knowledge to profitable use. Observing the cauldrons or analysing the permanence is very time-consuming. The casino operators also check the cauldrons regularly and replace a conspicuous cauldron, usually before the players can exploit cauldron errors. Cauldrons with serious defects, where favourites quickly crystallize out, do not survive the manufacturer’s tests and are never used. In online games, the algorithms ensure fair and correct game play.

Throw distance game

The supporters of this variant believe that a croupier is able to hit certain segments of the boiler preferentially. Or that there are relatively constant distances “widths” between the individual throws. If the player thinks he can interpret the croupier’s throws correctly, he plays the number that is favoured and the side numbers of this number in the cauldron.

Bowl watching

“Kettleguckers” try to set as late as possible, because they are sure that after a few rounds of the ball they will be able to better estimate the sector of the kettle in which the ball will come to rest. By cancelling the game earlier, it is easy for any casino to protect itself against such players.


No system that tries to do without cheating is capable of defeating probability. Play in casinos with “French” boiler as in the live and do not let you systems be talked up. In principle, the higher the expected profit is, the higher the risk of losing:

  • Red / Black stake CHF 100,– payout CHF 100,– 18 numbers play against 19 numbers
  • Whole number Stake CHF 100,– Payout CHF 3500,- 1 number plays against 36 numbers

Good luck playing at and stay curious.
