Fibonacci was an Italian mathematician in the middle ages, who wrote about a set of numbers called the Fibonacci series. These numbers form the basis of the Fibonacci roulette strategy.

The Fibonacci series

This numerical series starts with two 1’s. Each successive number is the sum of the two numbers before it, so the series continually increases.  1+1 = 2, then 1+2 = 3, then 2+3 = 5. Here is the start of the series.

1 – 1 – 2 – 3 – 5 – 8 – 13 – 21 – 34 – 55 – 89 …

How the strategy works

1)  You start at the first one, and bet on one of the even money bets such as Odd or Even.

2)  Whenever you lose, you move forward in the series, and bet the next amount on the next spin.

3)  Whenever you win, you move two steps back in the series, and bet that amount.

4)  Keep repeating this process until you are back at the beginning of the series (including the two 1’s).  At that point, you will have won 1.

Pros of the Fibonacci strategy

• If you keep working the system until you get back to the beginning, you will end up with a win.
• When you play through a string with more losses than wins, this strategy can still return a profit, when flat betting would have given you a net loss.
• It is not as risky as the Martingale system, in which you double your bet after each loss. In Fibonacci, the bets go up more gradually, so you have less at stake.

Cons of the Fibonacci strategy

• You may have to play a long time to get back to the beginning of the series, to get a profit of 1.
• You always need to keep track of where you are in the series, and what your next bet will be.
• The further into the series you get, the bigger your risks are on each spin. It is possible to have a long string of losses that leaves you in a deep hole.
