The Fibonacci Strategy: Golden Ratio of Roulette Games

Let’s start with who Fibonacci is. His full name is Leonardo Fibonacci, and he is a famous mathematician who lived in the 12th century. As can be understood from this knowledge, he has no connection to roulette games: in fact, during his lifetime, there was no such thing as roulette.

This famous mathematician discovered a sequence that is still in use today: Fibonacci numbers. These numbers are infinite and consist of a doubling sequence. That means each number in the sequence is the addition of the previous two numbers. It is not that complicated, let’s explain it by giving an example: 1 – 1 – 2 – 3 – 5 – 8 – 13 – 21 – 34. 1 + 1, the result is 2. 2 + 1, the result is 3 and so on. The sequence goes forever like this.

Well, what does this sequence have to do with roulette games? Fibonacci numbers are related to the “Golden Ratio”. In other words, they are often seen in nature and influence many people. Even if you are unaware, most online casino websites are designed according to the Golden Ratio: these designs are more liked and seem more “natural”.

Gamblers believe that this sequence, which can also be seen in nature, can also be used in casino games. The system is particularly common in the UK but is known and practised all over the world. So, does it really work? If you prefer to play real money roulette games, should you use this strategy? Let’s take a look at it together.

10 Rounds of Using the Fibonacci System

Round 1 2 3 4 5 6 7 8 9 10
Bet (£) 1 1 2 3 5 2 3 5 2 3
Outcome Loss (-1) Loss (-1) Loss (-2) Loss (-3) Win (+10) Loss (-2) Loss (-3) Win (+10) Loss (-2) Win (+6)
Balance (£) -1 -2 -4 -7 3 1 -2 8 6 12

How does the Fibonacci Roulette Strategy Work?

Fibonacci is a progressive strategy, so you have to increase your bets every round. But you know exactly how much you need to increase and which bets to place in advance. Simply put, you use the numbers in the sequence as your bet amounts. So until you win, you are betting like 1 – 1 – 2 – 3 – 5 – 8 dollars.

The Fibonacci strategy is considered as a system with a medium risk ratio. As your bets are increasing in a controlled way, you do not lose too much in a short amount of time. To use the system, you only need to deposit 4 betting options: Odd / Even, Red / Black, 1-18, and 19-36. You can choose any one, but you cannot use any other bet types. This is because these betting options offer the best chance of winning.

The system works on both European and American roulette (click here to find out the differences between these two categories). However, you should prefer the European version because you are more likely to win.

Let’s give an example:

  • Start by depositing 1 dollar for any of the 4 bet options mentioned above.
  • If you lose, deposit 1 dollar again.
  • If you lose, put 2 dollars.
  • If you lose, deposit 3 bucks.
  • Still losing? Place 5 dollars this time.

No need to extend further: as long as you lose, you need to use the numbers in the Fibonacci sequence as your bet amount. So you’re entering bets like $ 5, $ 8, $ 13, and $ 21 respectively. When you win, you have to go back two rows in the sequence. For example: If you bet 21 dollars and win, your next bet should be 8 dollars.

The system repeats itself this way. Good, but does it really work?

Is Fibonacci Strategy Good for Real Money Roulette Games?

You should have guessed that the Fibonacci strategy is not about winning chances. This system only controls your bet amounts. Since there is no connection between the number of bets and the chance of winning, it simply does not work. This is just the “Gambler’s Fallacy”, which we have mentioned before in many of our articles. The odds of the options you are betting are only 47%. This rate also shows your chances of winning. Using the Fibonacci strategy does not increase or decrease this percentage.

Is it reasonable to set the betting amounts by using this system? Unfortunately, the answer to this question is also no. The most important feature of Fibonacci numbers is that they start to increase in a very short time frame. Do you remember that famous tale about the placing rice grains on a chessboard? Well, that was the Fibonacci sequence. After 34, all the numbers in the sequence are rising at a terrible pace. So if you invest 34 dollars according to this strategy and still cannot make a profit, you will start to lose money very fast.

All the guides recommending this strategy accept “34” as the last bet and assume that you will win until you reach that number. In reality, there is no such “guarantee”. After only 8 rounds you will reach a bet amount of $ 34. After the tenth round, each bet will cost hundreds of dollars. It will not take long to reach the table limit, and if you still didn’t make a profit until then, you will go bankrupt. It is not a logical choice to set your bet amounts according to the Fibonacci numbers: if you cannot win during the first 4 or 5 rounds, you are likely to suffer. Even if you win, the profit you get will be pretty low. In short, the Fibonacci strategy does not work at all. Even the Martingale strategy sounds more reasonable than this one, and guess what: it doesn’t work too.
