The Fibonacci Roulette Betting System

The Fibonacci betting system for roulette builds on the number sequence starting with numbers 1-1-2-3-5-8.
This famous sequence goes all the way back to the 13th century and has a peculiar habit of showing up in completely unrelated areas of life such as architecture, music and biology.

1 - 1 - 2 - 3 - 5 - 8 - 13 - 21 - 34 - 55 - 89 - 233 - 275

How to Calculate Fibonacci Numbers

It is very easy to calculate the next number in the Fibonacci sequence: just add the two previous numbers, starting from 1-1!


1+1 = 2

1+2 = 3

2+3 = 5

3+5 = 8

5+8 = 13 etc.

How to Use Fibonacci Numbers in Gambling

In roulette, the Fibonacci sequence gives rise to a betting system that is somewhat "cheaper" than the Martingale system, but also a bit "slower".

That is, the size of the bets doesn't grow as fast, but you'll have to play more rounds before the sequence ends - on average.

When you lose:

When using the Fibonacci roulette system, each time you lose a round you increase the bet size on the next round, just like in the martingale system.

But instead of doubling it, you follow the Fibonacci sequence.

For example: Start by betting 1 unit. If you lose, bet 1 unit. If you lose a second time, bet 3 units, then 5, then 8, and so on.

When you win:

When you win a round, you don't end the sequence at once like in the Martingale case. Instead you cross out the last two numbers in the sequence and bet the new number.

The sequence ends once you're back to betting 1 unit.

For example: You bet 13 units and win, you cross out 13 and 8. Your next bet is 5 units.

If you win again, cross out 5 and 3. Bet 2 units.

Example of a Fibonacci Betting Sequence


This is how a typical Fibonacci betting sequence may go:

Bet 1: Lose

Bet 1: Lose

Bet 2: Lose

Bet 3: Lose

Bet 5: Win - cross out 5 and 3

Bet 2:

Bet 3: Win - cross out 3 and 2

Bet 1:

End the sequence: start over with 1 unit


Just like with the Martingale system, this one will work fine for a while, but you'll eventually hit the betting limit that is set either by the online casino or by your own bankroll.

Nevertheless, playing the Fibonacci roulette system is bound to give you a good time at the table and enhance your overall roulette experience.

When clearing a casino bonus the Fibonacci system is preferably used. The bets using this system builds slower than the Martingale system. When playing with a system a large bankroll is an important factor.
