Explanation and Tests of Best Roulette Strategies

According to Google, thousands of UK residents searched “roulette strategy” every month throughout 2022. This would seem to indicate that roulette players in the UK are effectively trying to find proven systems to beat the game and ensure they have the upper hand. Yes, there is indeed a vast amount of information about roulette strategies on the Internet. However, one reason for this is that authors of such information simply rewrite what others wrote. This can easily lead to false and unfounded conclusions that don’t help anyone. So, is there one particular strategy that can help you win every time?

The answer to that question is rather complicated. To begin with, no roulette system guarantees profits. Instead, they are designed to give you the best chance to win. If there was a 100% guaranteed way to win at roulette, then it would no longer be a gambling game, and casinos would stop offering it.

At Roulette77, we know what to expect when picking a roulette strategy and we know why certain strategies may be more efficient than others. Our team has rigorously tested some of the most popular betting systems to provide you with the upper hand that you need to make sure you are really giving yourself the best opportunity to win. Analyzing and explaining popular roulette strategies also ensures that your understanding of the different methods is sound.

Testing Roulette Systems

The most effective way of knowing if a roulette system is working is by putting it to the test. We have tasked ourselves with testing dozens of popular strategies that are viewed as mathematically-sound and efficient. While you can only learn one strategy at a time, having access to more patterns will allow you to be more flexible in your approach to roulette betting.

Before you randomly select a strategy and run with it, you have to make sure that the strategy that you set actually can lead to desired results. This is where we come in. We ensure that all strategies produce statistically-relevant results that help you play your best game and achieve the best possible results.

We used demo games to sample some strategies. For others, we used a random number generator with a simulation of programmed moves that exactly repeats the roulette game’s mathematical model. Since one round does not provide a large enough sample size, we have simulated thousands of roulette wheel spins to provide more 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. In other words, a strategy can contain multiple 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 come across. Essentially, this system requires players to double the size of their bets after every loss. The idea is to recover your previous losses. Once you do, you return to a base betting unit and continue betting with the base unit until you lose. Then you double down again.

    About Martingale system
  • Reverse Martingale Strategy
    Roulette77 Strategy 2

    Reverse Martingale

    As the name suggests, the Reverse Martingale system is the opposite of the aforementioned Martingale system. Here, you will double after every win. You double until you score a loss. When you lose, you will return to the base unit and keep on betting the base unit until you win. Then you double down again.

    About Reverse Martingale system
  • Grand Martingale Strategy
    Roulette77 Strategy 3

    Grand Martingale

    With this system, you will bet the same amount until you lose. When you do lose, you then double your wager and add one unit on top of it. This way, you seek to recover the bet you have lost whilst also scoring a bit of profit along the way. It’s really an alternative version of the Martingale system.

    About Grand Martingale system
  • D'alembert Strategy
    Roulette77 Strategy 4


    D’alembert is another floating roulette tactic used by professional players. With this system, you will add one unit after a loss, and you will decrease your bet size by one unit after you manage to win a wager. You keep doing this throughout the duration of the session.

    About D'alembert system
  • Labouchere Strategy
    Roulette77 Strategy 5


    Labouchere tells you to come up with an amount that you want to win. They then create a sequential list of positive numbers that add up to the target win amount. Each stake amounts to the sum of the first and last number on the list. If you win a bet, then you remove the two numbers you used from the list. If you lose the bet, you add that bet amount to the bottom of the list and keep playing.

    About Labouchere system
  • Fibonacci Strategy
    Roulette77 Strategy 6


    Fibonacci is a system that is tied to a sequence of numbers. After starting with 0 and 1, each number in the sequence equals the total of the previous two numbers. All you do is move up or down this system’s numbers and adjust your bets accordingly, depending on whether you win or lose.

    About Fibonacci system
  • Romanowsky Strategy

This gives you around an 86.5% chance of success and a 13.5% chance of losing. It’s considered to be a relatively sound short-term system that can help you adjust on your feet and incorporate other strategies.

A lot of roulette buffs swear by this method.

    Contra Bet

    Contra Bet is also known as Contra D’Alembert. This strategy requires you to bet on even chance bets like Even/Odd, Red/Black, or Over/Under.

    Roulette77 Strategy 10

    Shotwell Strategy

    This is a relatively new strategy that has been around since the 1970s. In it, players will have two sets of bets to use at their disposal.

A Word of Warning

Whilst using a strategy can feel empowering, it’s important to keep in mind that no scheme or tactic will give you a 100% chance of making a profit. The house edge is there for a reason, and, in the long term, the casino always wins. This isn’t a myth. The odds of racking up nine or so consecutive losses are indeed very long, but it’s possible nonetheless. The above-mentioned strategies are excellent foundations for approaching roulette as long as you know what to expect. Remember that using such a strategy can improve your chances of winning in short to mid-term. At the same time, they can become a lot riskier when you are behind.

It’s also immensely important to understand the limits of your bankroll as they relate to the table limits. Some of the methods we have covered are better suited for smaller bankrolls, while others work better with big bankrolls. We urge you to try some of these strategies in demo mode before you commit real money.

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

What to Consider when Choosing a Roulette Strategy

Picking a roulette strategy is often a deeply personal thing, but there are many practical and objective factors to consider too. We now present you with several factors to mull over when choosing a gambling strategy.

  • Expected value and volatility

    It is essential to understand that the expected value in a casino is always negative. This means that the longer you play, the more likely you are to lose money. That is why it is critical to consider this when choosing a strategy for the game. Some strategies are more straightforward than others, but you always have to account for your chances of losing a wager. Some plans of attack give you good odds of winning, but better odds of winning often equate to smaller wins.

  • 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 maximum effect. This is because you have a chance of encountering problems if you hit the betting limit too soon. Only choose a roulette table where the limits will allow you to implement and maintain your system.

  • How much money you have

    To pick a betting technique, you also need to account for how much money you have. Is your bankroll big enough to battle through losing streaks? Or do you need an advanced strategy that offers more profitable outcomes if you make the right bets? Bankroll is a key consideration to factor in. This is especially true if you use progressive strategies. You need to make sure that you have enough starting capital to make a strategy work.

  • 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. In addition to that, those who play live dealer roulette need to be able to place their wagers in a certain amount of time. This can pose a challenge if your system calls for multiple simultaneous bets.

  • What type of game are you playing

    Some techniques will work better with specific variants of roulette. Mathematically speaking, you have a better chance of success if you play European roulette. American roulette comes with two zeroes which increases the house edge. This is why you should always be prepared and aware of what to expect by choosing one roulette version over another.

! Important Facts and Tips

The odds are 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. You may win in the short term, but you will almost always lose in the long run. That’s just a fact of life. It’s important to be conservative and not take unnecessary or impulsive risks. After all, the expected value in the casino is always negative 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 readily and freely available to you. Do not trust anyone who tells you there is a secret formula to guaranteed roulette profits. If such a strategy existed, then casinos would simply stop offering roulette.

#1 Google results for roulette strategies do not always work

While you may be inclined to click the first results of a Google search, 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 probably is. As such, you should look for a more informed source!

The strategy test needs at least 1,000 spins to justify

This is true. The only way to test if a strategy works is to run it through more times. Why? Because there is a much larger margin for error in smaller samples. All casino games that use a Random Number Generator are tested over 100,000 times to confirm the accuracy of the advertised return to player. The same concept applies to testing betting strategies.

There’s a Lot More to Know

It only makes sense that you would want to know more about the way roulette strategies work. This is why we have put together a list of additional resources and materials about roulette. It’s worth remembering that Roulette77 offers a comprehensive guide of strategy resources that are designed to elevate your gameplay and help you find new information about roulette. We are constantly updating our database with the latest findings to give you a true edge in succeeding at your next roulette session.

Playing roulette can be fun as well as rewarding. Don’t worry if you have a small starting bankroll because it should be enough to get you started. With the right strategy, you should be able to get the most out of your roulette experience both in terms of fun and profits. Whilst there is no magic formula and the odds are stacked against you, a solid approach will make roulette that much more fun.

Remember to pace yourself and always consider withdrawing your funds if you feel like you have amassed a healthy bankroll. Remember, your chances of losing increase the longer you play. Strategies may give you a better shot at success, but you will still need to show a little discretion.

Roulette77 brings you all the best possible proven strategies. We have tested each system and provided you with the conclusions. Of course, we don’t mind if you disagree with them. After all, you are the one who ultimately decides which plan is best for you. In any case, we would like to wish you good luck and remind you to keep a level head when you indulge in roulette or any other form of gambling.


Are there any systems that guarantee profits?

Anyone who claims to have a guaranteed roulette system is lying to you. No such formula exists. However, some systems can go a long way toward earning a profit in the short and medium terms. 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 know when to walk away.

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 and run into several consecutive losses, you will eventually be unable to double down again and recoup your losses. This is the main problem with this strategy. Also, do not forget about your bankroll. A few losses in a row might leave you financially incapable of continuing with the system.

What is the house edge, and why does it matter?

The house edge is best described as the mathematical advantage that the casino holds over the player. You may win some money in the short term, but the law of large numbers says that the house will eventually win it back and then some over time. If a game has a house edge of 97%, this means you can reasonably expect to lose £3 for every £100 you wager. Of course, this is merely an average. You could win money, lose more than £3, or break even. That’s gambling for you!!

Are there any illegal strategies for roulette?

No. All strategies that rely on chance and mathematical probabilities are completely legal. The ones we have discussed here are certainly legal. You can think of it in terms of counting cards in blackjack. Whilst it isn’t illegal to do it, casinos understandably don’t like it, and they have the right to give card counters the boot. The only time a strategy would be considered illegal is if it entails interfering with or manipulating the game in any way. Of course, that’s cheating and not a strategy.

What are the least risky strategies?

Generally speaking, Reverse Martingale and D’alembert tend to be the less risky strategies. They are easy to grasp and employ, which is something that players definitely appreciate. They want a simple and straightforward path to victory, and all of the strategies listed here are suitable for that purpose.
