tested a million times

I recently decided to test 6 most popular roulette strategies to see which one performs the best.


So I tested each strategy a million times.

Bitcoin roulette strategies

Why did I decide to do this?

I’ve been playing Bitcoin roulette at different Bitcoin casinos and like me I assume you have come across a few posts or articles mentioning any of the theories and telling you in conclusion that none of these theories can help you win.


While that is true, it’s not exactly true. These strategies can’t guarantee 100 % that you’ll walk away with more than you came with at the end, but they can still help you double your money. But which one will help you the best?


While I knew that playing each strategy can’t guarantee me doubling my money, I wanted to know which strategy has the best odds in helping me do that anyway if I stick to it no matter what and use it every time I play roulette.


Before I dive into my million test and show you why the Reverse Martingale strategy is the best roulette strategy, let’s briefly look into each strategy that was tested and how it differs from the others.


I tested 6 best roulette strategies:


I’m guessing someone might have done this same test at some point in the long history of roulette (which is around 300 years to quote my friend, Wikipedia) but I haven’t found anything similar anywhere online, so I decided to do the test myself and share the results with all of you.


Here’s a quick summary of what I discovered:

  1. The James Bond roulette strategy did the worst by helping me only 26 % of the time.
  2. Strategies, which doubled my money the fastest are the Labouchere and the Reverse Martingale strategies. They helped me do that on average with 18-19 bets.
  3. The strategy, which kept me on edge the longest by taking a very long time to double my money is the Fibonacci strategy. It had me waiting on average for 216 bets which also makes it the safest roulette strategy to use.
  4. As already mentioned, the best, most reliable strategy, which helped me the most times is the Reverse Martingale roulette strategy. With it I managed to at least double my money over 43 % of the time.
  5. The strategy, which let me have fun the longest, whether I doubled my money at the end or lost it all, is the Fibonacci. I played every game on average for 381 bets.
  6. And the strategy which ended my games the fastest and either helped me double my money or crash-landed me to 0 the fastest is the Labouchere roulette strategy, where I played on average for only 14 bets.


Let’s look at the strategies.


The Martingale roulette strategy is probably the most known and most popular among all strategies and it belongs into a group called progressive betting strategies.

The Martingale strategy relies on even money bets. That means betting on red/black, even/odd or 1-18/19-36, where the payout is always 1:1.


The strategy is very simple to use: you choose your preferred initial bet and bet with it every time you win or double your previous bet every time you lose.

Martingale roulette strategy

The doubling of your previous bet is to cover your losses along with winning some more to put you back in the green numbers.


But this strategy is also very risky to use because a lot of bad things can happen very quickly.


Let’s say you start your betting with $2. If you lose, your next bet is $4. If you lose again, it’s $8, then $16, $32, $64, $128 and so on.


Losing a couple times in a row can increase your bets drastically and you therefore risk losing all of your money very soon into the game. Unless your wallet is very deep and very full but I guess in that case you already have a better way of doubling your money then the rest of us.


While also a progressive betting strategy, the system here is reversed as the name suggests.


The Reverse Martingale strategy, also known as the Paroli system, also relies on even money bets and only reverses or turns upside down the Martingale strategy.


You double your bet every time you win or restart with your initial bet if you lose.

Reverse Martingale roulette strategy

The idea here is that you don’t increase your risk by betting more if you are losing. But since you’re doubling your bets when you win, you basically keep betting everything you have won until you stop and go home or lose it all back again.


For example, you walk into a casino with $2 (that must be some confidence), bet and win. Now you have $4. You double your bet, which is now $4 and win again. You now have $8, double your bet again to $8 and so on.


As long as you’re winning, you bet everything each time. But if you lose, you lose everything as well.


Both the Martingale and the reverse Martingale strategies have steep progressions because you double your bets. Steep progressions carry the most risk, because things change very fast due to fast increasing bets but can also win you a lot of money in case you land on a winning streak.


This strategy is named after the mathematician, Jean le Rond d’Alembert, who created this betting system in the 18th century.


It is quite similar to the Martingale strategy, also relying on even money bets but slightly less risky due to its less aggressive progressions.


The d’Alembert strategy requires you to set your initial bet and the amount to increase or decrease your bets with.


Instead of doubling your bets when you lose, you will be adding a certain amount to your previous bet each time or decreasing your bet by the same amount if you win.

d'Alembert roulette strategy

So for example, if you start betting with $2 and lose, you add $1 (or another amount you’re comfortable with) and then bet $3. If you lose again, you increase by $1 again and bet $4 and if you win, you decrease the bet by $1. But you never go below your initial bet.


Experts recommend setting your increase/decrease amount to 0.33 % or 0.5 % of your total funds so if you lose a few times in a row, your bets don’t sky-rocket.


Allowing you to set the increase/decrease amount as you prefer allows you to determine the risk you’re willing to take. Higher number = higher risk, lower number = lower risk because this number determines the aggressiveness of your progressions.


This strategy is also named after a mathematician, Leonardo Fibonacci, who designed a sequence in the 12th century. It goes like this:


1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …


Basically every number, except the first two, is a sum of the previous two numbers.


Like the d’Alembert strategy, the Fibonacci strategy also uses increasing and decreasing your bet if you win or lose making even money bets. The only difference is that Fibonacci doesn’t let you choose your own increase/decrease amount but it follows the Fibonacci sequence instead.


You start your betting at the beginning of the sequence and move up one if you lose or move down two in you win.

Fibonacci roulette strategy

For example, you bet $1 and lose so you move up one number in the sequence, which is 1 again. You bet $1 again and lose. You move up one again, which is now 2. You bet $2. If you lose again, you move up to 3 and if you win, you move two down to the first 1 in the sequence. Needless to say, you can’t move further down from the first number 1 in the sequence.


If calculating the sequence in your head as you play is effortless to you or if you write it down somewhere, the Fibonacci strategy is very easy to use and it eliminates the risk of poorly choosing your bet values if you don’t know exactly what you’re doing when using the d’Alembert strategy.


Otherwise, like the d’Alembert strategy, the Fibonacci roulette strategy is a flat (opposed to steep) progressive betting system.


Before you jump to any conclusions about this strategy having something to do with number 7, let me tell you, it doesn’t.


In the book ‘Casino Royale’ Mr. ‘license to kill’ James Bond takes a shot at roulette, where he plays with his own system.


Unlike all strategies up to this one, the James Bond roulette strategy is not a progressive one. This means you won’t be increasing your bets. And unlike all strategies up to this one, the James Bond roulette strategy doesn’t place bets only on even money bets.


Here’s how it goes.


For every spin the following bets are placed: $14 on 19-36, $5 on the six-line bet (13, 14, 15, 16, 17, 18) and $1 on 0. That’s $20 altogether. If you wanted, you could increase your bets here, so they sum up to $200 or $2000 or similar. But they must be in the same ratio.


This way, you bet on all numbers except 1-12 every spin. This increases your odds of winning, since you’re betting on the majority of numbers but you can also lose more.


These are the possible outcomes:

  • if the ball lands on 0 (payout 35:1), you win $35 and end up with $15 profit,
  • if the ball lands on 1-12, you lose $20,
  • if the ball lands on 13-18 (payout 5:1), you win $25 and end up with $5 profit,
  • if the ball lands on 19-36 (payout 1:1), you win $28 and end up with $8 profit.


It seems like James Bond beat the odds right?


Unfortunately, no.


The problem here is that although you will win most of the time, you will win much less than you will lose the rest 33 % of the time.


Since no matter where the ball lands the odds are the same, you should get a feeling where Mr. James Bond would take us if we spin the wheel 37 times and a different number falls each time.


Let’s calculate our winnings: $15 for 0, 6 times $5 for numbers 13-18, 18 times $8 for numbers 19-36 and 12 times -$20 for numbers 1-12.


$15 + 6*$5 + 18*$8 – 12*$20 = -$51


That means you will have $51 less on average every 37 rounds.


This last strategy is the most complex to explain and to follow.


Named after a 19th century aristocrat, Henry Labouchere, it also utilizes even money bets.


First you must decide how much money you want to win. Let’s go with $10 for this example.


Then you split the amount into a sequence of smaller numbers, which add up to your winning amount. In this case let’s make it 1, 2, 2, 3, 1, 1. It can be anything really, any length and any numbers you want as long as they add up to your winning amount.

When making a bet you always take the first and last number in the sequence, add them together and bet that value. In this case, the first bet is 1 + 1 = 2 $.


If you win, remove the numbers you bet on from the sequence. That would result in 2, 2, 3, 1 and the next bet would be 2 + 1 = $3.


If you lose, add the value you just bet to the end of the sequence. That would result in 1, 2, 2, 3, 1, 1, 2. This way you have to bet what you just lost and a bit more to compensate your losses.


Then continue until you run out of your sequence or run out of money.


The Labouchere roulette strategy is also a progressive betting system because it increases your bets when you lose.


Now that you know the main differences about the six tested roulette strategies, let’s look at what stands out if you choose each of the strategies and use it as your loyal betting system.


Before I dive in, here’s how I played: I always started with $100 in my pocket. My initial bet was always $5 (except for the Fibonacci strategy, where all bets were predefined). My goal was to try doubling my money, so I always walked away when I reached $200 or continued to play until I lost all my money or until the bet got higher than what I had left.


I wanted to know how many times I will be able to walk away with $200 if I use each roulette strategy a million times, which strategy will help me achieve my goal with the least and the most bets, which strategy was the most fun and which one was the worst.


I have to admit, I was surprised by some of the results I got. Here they are.

% of games where I doubled my money vs. % of games where I lost it

best roulette strategy

average final sum of my money when walking away after doubling it

roulette strategy that wins you most

average number of bets needed to double or lose my money

roulette strategy with most bets

average number of bets in a million games

roulette strategy with the most bets


The bars of the top right chart show how much money I had at the end of all games I won, averaged out. That means when I reached $200, I walked away, but it was rarely exactly $200. So how much did I win exactly? As you can see, it was always more then $200, with some strategies only slightly more and with others significantly more.


That is expected because your bet amounts vary from spin to spin with every strategy except the James Bond strategy and it would be a big coincidence to end up with exactly $200 at the end of a win.


What’s more interesting is that the Fibonacci, Labouchere and Reverse Martingale left me on average with significantly more. I know that’s always good news but can it help you?


Actually, yes.


If you’re sticking to one strategy and always play until you either double your money or lose your money, that means you either win more than $100 on top of your initial $100 or lose the initial $100 or less.


Why would you lose less? Because if you’re strict about your betting system and you end up with $30 for example but need to bet $37 on your next spin according to your strategy, then you can’t do it and you finish the game. That means you didn’t lose $100 but only $70.


Let’s stop here for now and just remember this scenario. We’ll circle back to it at the end of this article.


The bottom left chart shows the average number of bets I had to make with each strategy to either double my money (green bars) or lose my money (red bars).


What does this tell me?


4 out of 6 strategies took more bets to double my money than to lose it, which means I can’t rely on doubling my money until it actually happens. Or I lose it all along the way.


But the Fibonacci and the Reverse Martingale strategies show an inverted trend. Meaning that it took more bets on average to lose than to double my money. Which means I have the ability to predict whether the game I’m playing is heading to me losing my money or not.


If we take the Fibonacci strategy for example, I could add another rule to my betting system: if I don’t succeed in doubling my money in 216 rounds, I stop playing no matter how much money I have left. I could play with this number and set it to 220 or 250 or 300 instead of exactly 216, it doesn’t matter, depends on how safe you want to play.


This decreases your risk of playing tremendously. And if I return to “loosing less than $100” from the previous section, this information helps me lose even less because I don’t walk away when I don’t have enough money any more to place the next bet but I walk away sooner, according to my statistic of playing a million roulette games with this strategy.


The same scenario applies to the Reverse Martingale strategy but the “walk away” window is smaller because the overall number of bets is smaller.


As long as I’ve known roulette and different players, I’ve also known that they play roulette for two different reasons:

  1. To win some extra money or
  2. to have fun by gambling.


Even though the aim of my million games strategy test was to help you with the first goal, let me say two sentences about the second one here.


If you’re looking to have fun, I’m assuming you want to play as long as you can without losing a fortune. Which means you want to make as many bets as possible during a single game without reloading your wallet.


According to the bottom right chart, the Fibonacci strategy is the obvious winner here by far, which let me play almost 400 bets per game on average regardless of either losing or doubling my money at the end. That is about 12 times more than any other strategy.


Of course, I saved the best for last.


As you can see from the first chart where the green areas represent the percentage of all games where I walked away with at least $200 in my pocket, no strategy allowed me to do that in 50 % or more. But don’t get discouraged just yet.


That result makes sense and was expected. Roulette strategies can’t help you beat the casino’s house edge, so your odds are always below 50 %.


However, this is the time to remember the scenario from the “How much did I walk away with?” section: “… you either win MORE than $100 on top of your initial $100 or lose the initial $100 OR LESS.”


Taking that into account means that even though I lost more than 50 % of the games with any strategy, I almost always lost less than I won when I managed to at least double my money.


Let’s put this into an example to help us get a better picture: I won 38.9 % of the games with the Reverse Martingale strategy and the average amount I was left with at the end was $258, that’s $158 on top of my initial $100. Let’s be pessimistic here and assume I lost every cent when I lost the rest 61.1 % of the games.


After 100 games:

100 * 38.9 % * $150 + 100 * 61.1 % * (-$100) = $36.2


That means I had $36.2 more after 100 games than I had at the very beginning. After 1000 games I had $362 more, after 100 000 games, $36,200 more, …


See where I’m going with this?


And I was pessimistic in this scenario by assuming I actually lost all $100 61.1 % of the time when in reality I almost always lost less.


But let’s not just stop at this example. Here’s another chart showing my wins-losses after each of the 1,000,000 games played with each roulette strategy.

average number of bets needed to double or lose my money

As you can see, I managed to turn a profit with 3 out of 6 strategies after a million games. However, this isn’t one of those black-and-white scenarios.


To fully understand what was happening we must look at the whole way, from the first to the last game. After the first few thousands of games I was staying on a very promising winning journey with the Martingale strategy but then started loosing at around 250 000 games and never recovered again. While on the other hand, I started losing very soon with the Reverse Martingale strategy but then recovered at around 350 000 games and remained profitable.


But in order to get to my final $163,500 profit with the Reverse Martingale strategy I needed to lose almost $69,000 along the way.


So, considering all this data, I must say the Reverse Martingale strategy nevertheless seems like the most promising strategy to use. It didn’t have the highest percentage of games won but close enough, it earned me a lot of money exceeding my set $200, it required more bets to lose than to win on average to allow me to play it more on the safe side and it left me with the most profit at the end.


Again, I have to admit, I didn’t expect the results to turn out this way.


I certainly didn’t expect the James Bond strategy to be the worst but then again that only proves that first appearances can be deceptive so don’t put your trust into a strategy just because it ‘looks good’.


To conclude, this would be my advice to all roulette players in search of a strategy:

  • To try and win the most, use the Reverse Martingale strategy, set your winning goals ahead of playing and stick to your rules and your strategy. And most of all, remember that this is a waiting game, results don’t come overnight. Know you’re always taking a risk so be prepared to lose your money before you win it back.
  • To play the safest possible strategy, the Fibonacci is the obvious choice. It may seem at certain times that you’re just going around in circles and nothing is happening but to be honest, that’s what playing on the safe side looks like: very little steps towards a greater goal.
  • Don’t just throw away the James Bond strategy. Try it out yourself, just don’t expect much in return (perhaps play a free roulette game first 😉 )
