How the Fibonacci Strategy Works

You simply start by putting down a low wager on one of the previously mentioned betting options. If you win you take your money off the tablet and go two steps back in the sequence shown below. If you lose you increase the size of your bet according to the Fibonacci sequence. You proceed with increasing your bets accordingly until you finally win. Overall this leaves you with a small profit.

The sequence is really simple: the next number is the sum of the two previous numbers. The series starts with two numbers - 0 and 1. Then the addition begins: 0 + 1 = 1 … 1 + 1 = 2 … 1 + 2 = 3, etc. 

1 – 1 – 2 – 3 – 5 – 8 – 13 – 21 – 34 – 55 – 89 – 144 – 233 – 377 – 610 – 987

You simply start with one chip as a bet. If you lose, move on to the next number in the sequence. You do that until you win. If you win, take two steps back down the sequence. To make it easier to understand, here is an example.


You start by placing your wager on an even-money bet of your choice. Let's say red. Black comes up. You place the same bet again on red and black comes again. Next, put two chips on top of black. Red appears. You repeat this three more times, with 3, 5, and 8 chips as stakes and you lose all rounds. You finally win the seventh round and receive 13 chips as a prize.

Now let’s say you win two more rounds and end up at the beginning of the Fibonacci sequence since you moved two steps back each time. But what is the loss/gain of the entire round? -1, -1, -2, -3, -5, -8, +13, +5, +2, +1, = +1. So in total, you have won 1 chip.

You can see that you have to be patient with this system. There can also be rounds in which you end up with neither a profit nor a loss. The motto is to take your time and be satisfied with small profits.

The Benefits of the Fibonacci System

In contrast to the popular Martingale system, for example, the progression in the Fibonacci sequence is less steep and therefore less risky. This has the advantage that a smaller bankroll is required to even out a streak of bad luck.

In addition, only about a third of the bets need to be won to be positive overall. These are great incentives to try out the system yourself. However, we recommend being careful as this only works to a limited extent in the real casino environment. But we’ll explain why that is later. 

Try the Fibonacci System in an Online Casino

As soon as you are ready to test the Fibonacci system yourself, it is advisable to make sure you are familiar with the rules of the sequence. You can always use the numbers we posted earlier in this article as a cheat sheet.

It also might be a good idea to test the strategy with play money before you try your luck with your hard-earned cash. Most online casinos offer a free play mode where you can play online roulette games without any risk.

If you decide you are ready for the real deal we recommend looking for an online casino with a generous welcome bonus to further increase your chances of winning. 


Is the Fibonacci system banned in casinos?

Like all other casino strategies that are based on even odds and mathematical foundations, this system can be applied without hesitation.

Is the Fibonacci System suitable for sustained profits?

With this method, you can expect a lot of small wins and also some neutral rounds but losses are common even more often. However, since only a third of the rounds have to be won, wins and losses will offset each other over time. 

One thing you have to keep in mind is that all casinos have a set table limit. This is the weak spot of the strategy. If you lose too often you won't be able to progress through the sequence anymore as the table limit won’t allow you to increase your bet further. Ultimately, this means that the Fibonacci system doesn’t really work in the long run. 

Is the Fibonacci system suitable for beginners?

The Fibonacci system is well suited for beginners as the strategy can be learned very quickly. But even as a professional, you are welcome to try the system out. So if you are looking for a simple and easy-to-understand method before you set foot in the great land of roulette games, the Fibonacci system is the right place to start.
