Roulette Systems Tests

The best way to know if a roulette system actually works is to put it to a careful test. We have been pleased to test dozens of viable strategies that are welcomed as mathematically-sound and efficient ways to play. While you can only learn one strategy and stick with it, having access to more patterns will allow you to rotate them and throw the casinos off the scent.

But before you do that, you have to make sure that you are actually playing with a strategy that you can trust in the long term. This is where we come in. We ensure that all strategies produce statistically-relevant results that help you be on your best game and achieve the best synergies and efficiencies.

That is why we tested each strategy. To sample some strategies, we used a demo game. For others - a random number generator with a simulation of programmed moves that exactly repeats the roulette mathematical model. Since one game will not be enough for the precision of the results, we have made thousands of roulette wheel spins to provide reliable information about each strategy or system.

It is worth explaining the difference between the system and the strategy of playing roulette. A game system is a specific pattern of game behavior that works in particular conditions. At the same time, a strategy is a more complex and long-term solution that allows you to make adjustments in a long-term game scenario. A strategy can contain systems. Let’s take a look at some of the available strategies and systems now.

  • Martingale Strategy
    Roulette77 Strategy 1


    Martingale is the simplest strategy you will ever experience. Essentially, in this strategy, you want to double down on a loss so that you can recuperate it. Once you do, you return to a basic betting unit and continue betting with the basic unit until you lose – then you double.

    About Martingale system
  • Reverse Martingale Strategy
    Roulette77 Strategy 2

    Reverse Martingale

    Reverse is the opposite of the classic Martingale. Here, you will double after every win. You double until you score a loss. When you lose, you will return to the basic unit and keep on betting the basic unit until you win – then you double. It’s simple as that.

    About Reverse Martingale system
  • Grand Martingale Strategy
    Roulette77 Strategy 3

  • D'alembert Strategy

    About Shotwell Strategy
Strategy types

Caution Players

While a strategy can feel quickly empowering, it’s important to keep in mind that no scheme or tactics will give you a 100% chance of winning. The house edge is there for a reason, and in the long-term, the casino is always set to win – or so they say. But scoring nine losses on a roulette wheel in a row is indeed very hard and long odds. However, these strategies are still excellent guidance as to how you should approach the roulette hobby and what to expect. Remember that by using a stratagem, you are statistically way more likely to end up winning in short to mid-term. But for this, it is worth understanding what goal you set for yourself, understanding your initial bankroll data, for example. And depending on this, choose the most balanced method that, with a certain probability, could bring you closer to the goal.

Dr. Edward O. Thorp

Dr. Edward O. Thorp, American mathematics professor, inventor, gambler, author of the books "The Mathematics of Gambling", "Beat the Dealer", etc. who actually built a prediction machine for roulette once mentioned that:

You couldn't beat any of the major gambling games because if you could beat them they would have changed the rules or they would have gone out of business

Strategies by Types of Bets

We understand that players may have specific preferences, and this is why we want to always be of help and assist you. Therefore, we have put a list of methods that will work in relation to specific bets. You can, therefore, quickly navigate to those options that suit your playstyle best.

What to Consider When Picking a Strategy

Of course, picking a roulette strategy is often a deeply personal thing. But there may be practical and objective factors to also consider before you move on with a strategy. That is why we wanted to present you with several things to consider when choosing your preferred gambling strategy.

  • Expected value and volatility

    It is essential to have a clear idea of what the expected value in a casino is always negative, which means that in the long run, the longer you play, the more likely you are to lose. That is why it is essential to consider these factors when choosing a strategy for the game. Some strategies are more straightforward than others, and you have to account for your chances of losing a wager. Some strategies give you 63% or even more chance of winning or so claim, but sticking with Martingale is often an option that many new players consider first.

  • Table and betting limits

    Remember that Martingale relies on you doubling down after a loss? Well, you want to play at tables with higher betting limits if you are to use this strategy to its maximum and most optimal variation. This is because you have a chance of ending up running into trouble if you hit the betting limit too soon. Well, that is why you also want to ensure that when using a progressive strategy, you always choose a betting table where the limits will allow you to make the most out of your experience.

  • How much money you have

    To pick a betting technique, you also need to account for how much money you have. Is your bankroll a bit bigger and therefore capable of sustaining on a little more risk, or do you need an advanced strategy that offers more profitable outcomes if only you will make the right bets? Bankroll is a good consideration to factor in – especially in progressive strategies. You need to make sure that you have enough starting capital to make a strategy work put plainly.

  • How much time you have

    Time can be quite important for making strategy work in a roulette game. Some strategies will require that you rely on a flat progression of wagers and expect to win from those. However, this will naturally take more time. When picking a strategy, you must factor in how much time you want to play or have on your hands. In addition, it is worth considering that if you want to play live roulette with strategies, you must understand that the time to bet here is not much, usually up to 20 seconds, so you can not have time to make complex combinations of bets.

  • What type of game are you playing

    Some techniques will work better with specific types of versions of the game. So, to put it this way, you stand the best chance of success if you turn to a solution such as European roulette. American roulette comes with two zeroes, and many players agree that this can throw a real spanner in the works when looking to secure a victory or make a strategy work. That is why you should always be prepared and aware of what to expect by opting for one version over another.

! Important Facts and Advice

Long-term, the odds are stacked against you

Because of the casino’s house edge, there is no way to shake off the long-term advantage that the casino has over you, and that’s just a fact of life. However small, this house edge will work against you, so it’s important to be conservative and not take risks. After all, the expected value in the casino is always negative, as mentioned above, which means the longer you are in the game, the greater the chances of defeat.

Do not pay for “special” strategies

Never pay for strategies that promise you the roulette world. All info that you should know about roulette is already available out there, and it will definitely make it viable for you to win or lose standard amounts. Do not trust anyone who tells you there is a secret formula to success – there isn’t.

Google #1 Page roulette strategies do not always work

While you may be inclined to click the first results of Google only, we recommend that you try to stick with the best researched and justified sources. If you think something is lacking on Google's #1-page results, then it is, and you should look for a better-explained source!

The strategy test needs at least 1000 spins to justify

It's quite true. The only way to test if a strategy work is to have more spins it can be 1000 or more. It all depends on the strategy itself. Why? Because there is an error for margin in smaller samples. All casino games that use a Random Number Generator are tested over 100,000 times to confirm that the return-to-player is an X percentage. That is why the same applies to testing strategies.

Strategies will help guide you to success, but you will still need to show a little discretion. Roulette77 brings you the best possible stratagems that have been proven to work and be an efficient way to play this timeless classic of a game! We have tested and concluded each strategy, and we do not mind if you disagree with them. In any case, would like to wish you good luck and keep a calm mind while playing roulette.


How to win at roulette every time?

There is no magic sauce formula that you can use to truly win at roulette – the odds are stacked against you BUT (and it’s a big but), you can play and win in the mid to short term. You won’t win EVERY time, but you will win often enough to amass a small respectable profit, and sometimes, even more. It’s important to use smart strategies and be patient because this is what it usually takes to win at roulette over a period of time – patience. Keep to our list of strategies, and you will see that success isn’t so hard after all.

Does the Martingale system work?

The Martingale strategy works beautifully in theory. However, each roulette game has a max betting limit. This means that if you get unlucky to realize nine losses one after the other, you won’t be able to double down again and recoup your losses. This is the main problem with this strategy – what if you lose too many times, and the statistics say it’s possible to do? Also, do not forget about the depleted bankroll i.s. there may be a moment in the game when you do not have enough funds to place the next bet to compensate for losses. However, it’s still an excellent strategy to see if you can advance your gameplay based on it.

What is the house edge, and how to calculate it?

The house edge of a casino is determined by the number of 0s present in the game. For a European roulette wheel, the probability of success is 1:37. Then, you can use the formula of 1x1/37 = 0.0270270 x 100 to get 2.70270, which will put the house edge at 2.70%. The house edge is efficiently the casino’s mathematical advantage for every bet you pace. You see, without the zero, there would be no house edge at all because you can just bet on evens/odds bets and get a 50% chance. However, zero changes this dynamic.

Are there any illegal strategies?

No, all strategies that rely on chance and mathematical probability are, in fact, completely legal. A casino may still ask you to leave if you are using a strategy and only sticking to it, but there is nothing illegal in the fact that you understand the mathematical probabilities and want to give yourself the best chance of success. The only time when a strategy would be considered illegal is if you end up actually messing up with the game by moving the chips or trying to cheat the dealers.

What are less risky strategies?

Generally speaking, Reverse Martingale and D’alembert tend to be the less risky strategies. They are easy to grasp and get into, and this is something that players definitely appreciate. They want a simple and straightforward path to victory, and all of these strategies are actually fit for that purpose.
