Fibonacci Strategy

Fibonacci Strategy

The Fibonacci strategy is one of the safer routes an avid roulette player can take, despite being one of the more complicated ones — but the question lies in whether this system can actually bring home the gold. With this article, we seek to pick apart this betting system and explore all the minor details pertaining to how this method works. Let’s take a look!

What Is The Fibonacci Strategy?

The Fibonacci system was named after an Italian mathematician, Leonardo Pisano (aka Fibonacci). In the 13th century, Fibonacci studied Indian and Arabic mathematical sequences and came across specific patterns that occur in nature. These patterns can be spotted in everything from the spiral on a snail’s shell to the family tree in bees, and so, the Fibonacci sequence was born. It then made its way to casinos and online gambling, as more and more gamblers applied this sequence as a betting strategy in roulette.

The Fibonacci sequence is a system of numbers where the following number is the sum of the previous two. The sequence begins with the number one and goes on infinitely. This is what the Fibonacci sequence looks like: 1 — 1 — 2 — 3 — 5 — 8 — 13 — 21 — 34 — 55 — 89 — 144 — 233 — 377 and so on.

In the context of roulette, you do not need to actually start from one, but from any number — as long as you follow the logic of the Fibonacci sequence: one number is the sum of the previous two. Each number would correlate to your bet amount. Place any bet you like when testing out this strategy, but it is recommended to start from the lowest possible number in the sequence.

How Does The Fibonacci Strategy Work?

As we’ve discussed so far, the Fibonacci system is based on a series of numbers where one number is the sum of the previous two and can carry on infinitely.

It is wise to use this betting strategy specifically when setting even-money bets like Red/Black, Odd/Even or 1-18/19-36. It is not advisable to use this strategy on Inside bets as these wagers are inherently riskier and you are unlikely to break even.

The Fibonacci system is a negative progression method, so players would be required to increase their bet to the next number in the sequence every time they lose and decrease the wager on a win. Once they secure a win, players must move down two places in the sequence (or back to 1 if you’re at the start of the sequence).


To break it down further, take the following example:

Round Bet Outcome Balance
1 1 Lose -1
2 1 Lose -2
3 2 Lose -4
4 3 Lose -7
5 5 Win 3
6 2 Lose 1
7 3 Lose -2
8 5 Win 8
9 2 Lose 6
10 3 Win 12


With seven losses and three wins, the player still manages to make a profit. This is because the Fibonacci system aims to reduce the damage incurred from losses by capitalising on the probability of an eventual win. However, no strategy can guarantee positive results. Let’s take a closer look at the pros and cons of the Fibonacci roulette system.

What Are The Pros And Cons?


In comparison to the Martingale strategy, the Fibonacci roulette system is much less aggressive. It is also quite easy to understand — simply write the sequence down, and you’ll be good to go. The Fibonacci method is relatively flexible as well: even though the sequence begins with one, players can start with any wager of their choosing. It is advisable to begin from the lowest possible number, which is usually €0.10 (or currency equivalent) on roulette tables.


As with every other betting system, there may be a few risks incurred when utilising the Fibonacci. Hitting a losing streak will drain your bankroll rather quickly, so watch out for your bankroll! Unless you get lucky and hit a winning streak, you may not be able to cover for all of your losses.

This system does not improve your odds either, the house will always have the upper hand, especially when taking the zero and double-zero pockets into account. These numbers are not covered in even-money bets, so the house will always have an advantage.

Since this is a negative progression system, the Fibonacci roulette system's effectiveness is heavily dependent on the player’s bankroll. Remember to set up loss limits and manage your bankroll well. With this betting system, things can go downhill quickly, so it is highly advisable to always have a sound bankroll management system in place.
