# Fibonacci system

The Fibonacci system is one of the most interesting roulette strategies – and is safer than many comparable progressive methods like the Martingale. Despite its relative safety, the Fibonacci still has the potential to bring you some wins. While it’s still a progressive betting system, the increase of the bet is not as big as other such systems.

The Fibonacci system is based on a mathematical sequence of numbers associated with a thirteenth-century Italian mathematician of the same name. Fibonacci used it in order to estimate the growth of a rabbit population, but it has had many applications, including in the world of roulette gambling. ## Fibonacci Numbers

To use the Fibonacci System, you need to understand how the Fibonacci sequence works. The first number of the sequence is one, and it then proceeds by adding the previous two numbers together. The sequence therefore begins with the following numbers: 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on.

## How does it work?

It is important to remember that the Fibonacci System works with binary bets, such as Odd/Even, Red/Black and so on. Having decided on your initial stake, you then multiply this by the first number in the Fibonacci sequence to determine the size of your first bet. If you lose, you move on to the next number to establish your next staking amount and so on.

This increase in stake only occurs with a losing bet. If your bet wins, you have to move two places back down the Fibonacci sequence to find the level of your next bet. The long term aim of the system is to return to the start of the sequence at which point you will be in profit.

For example, let’s say your initial stake is R100 and your first five bets are losers. Using the Fibonacci sequence, your first and second bets would be for R100 each. Your third bet would be R200, and this would be followed by bets of R300 and R500. If your fifth bet was a winner, you would move two numbers back in the sequence to determine your next bet, which in this case would be R200.

## Pros and Cons of the Fibonacci System

The Fibonacci system attempts to strike a balance between maximising profit and minimizing losses.

Once you are used to the way a Fibonacci sequence works, it is fairly simple to operate, and many online gamblers feel reassured by the system’s grounding in a genuinely mathematical model.

That said, the system suffers from the same flaw that a number of progressive strategies have. Betting on binary outcomes will reduce the number of losing bets a player experiences, but there can still be significant losing runs. This can result in a dramatic increase in the size of the stake used. In turn, players may end up losing their bankroll or reaching the table limit and being unable to continue with the system.

As a result, the Fibonacci System is more suitable for roulette players with a significant bankroll and a grasp of the mathematical probabilities than for beginners.
