The Fibonacci Betting System – Ultimate Guide (2020 Update)

In this article we explain all you need to know about the Fibonacci betting system. This includes what it is and how it works, the advantages and disadvantages and whether it is a sustainable tactic.

The Fibonacci Betting System Explained

Leonardo Pisano, better known as Fibonacci, was an Italian mathematician and lived during the 13th century. Fibonacci, while studying how generations of rabbits breeding, came up with the world renowned ‘Fibonacci sequence’.

While you have most likely not heard of this man, his mathematical strategy may just win you some money, as his sequence has been adapted to conjure up a very clever gambling system.

So, what exactly is the Fibonacci system?

What Is The Fibonacci Betting System?

The Fibonacci system is a negative progression betting system designed by Leonardo Pisano. It works so that with every losing bet you must increase your stake. The idea of this is that you are more likely to win larger amounts on winning bets in comparison to the money you lose.

What Is The Fibonacci Betting System?

The strategy can be used for sports betting or for casino games such as blackjack or roulette and follows a set, naturally occurring mathematical sequence.

Following the sequence allows you to take a more calculated, emotionless approach to your betting; which in turn cuts out the mistakes of betting on a whim.

Fibonacci Sequence Formula

In the Fibonacci sequence, every new number equals the sum of the previous two numbers, so if we start with the number one, you will see this:

  • 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…

Fibonacci Sequence Formula

As you can see, starting from the beginning of the sequence, it is worked out like this:

  • 1 + 1 = 2
  • 1 + 2 = 3
  • 2 + 3 = 5
  • 5 + 3 = 8


So, now we know what the Fibonacci betting system is, let's look at an example.

The Fibonacci Betting System In Practice

As we have explained, the Fibonacci betting system is a negative progression system, which means that you increase your wager each time you lose a bet.

To use the system effectively, it is best to seek out bets at odds of even money. Evens bets give you roughly a 50 percent chance of winning and will double your money if you win.

Now it’s time to choose your wager.

To keep things simple, let’s imagine your wager is £1. All you have to do is follow the sequence. Let’s have a look at the sequence again:

  • 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…

With a stake of £1, starting at the beginning of the sequence, it would look like this:

  • £1, £1, £2, £3, £5, £8, £13, £21, £34, £55, £89, £144…

Every time you lose a bet, move one number to the right.

Every time you win a bet, move two numbers to the left.

If you haven’t moved up at least two numbers in the sequence before winning, then simply start at the beginning again.


Now let's look at another example in more detail.

  • Bet £1 (one unit) and lose
  • Bet £1 (one unit) and lose
  • Bet £2 (two units) and lose
  • Bet £3 (three units) and lose
  • Bet £5 (five units) and lose
  • Bet £8 (eight units) and win

Following on from this, because you have won, you would now move two numbers to the left of the sequence, from eight units back to three units.

  • Bet £3 (three units) and win

Again, because you have won, you would move two numbers back in the sequence, from three units back to one unit.

  • Bet £1 (one unit)

As each number in the Fibonacci sequence represents betting units, it remains very simple, regardless of your stake.

Let’s say, for example, your wager is £5, the sequence would now look something like this:

  • £5, £5, £10, £15, £25, £40, £65, £105, £170, £275…

The Pros

There are a number of advantages to the Fibonacci betting system. These include:

  • No matter how many times you lose a bet, providing you have the bankroll to place another stake, then you are eventually going to win all of your losses back – and then some.
  • The system is very easy to follow and requires very little thought process to play.
  • Due to the nature of the system, you will consistently build up a lot of small profits the longer you play.

The Cons

However, as with most systems, there are also disadvantages.

There is one huge risk in particular which is concurrent in all negative progression betting systems, such as the Martingale system and the Progression d’Alembert.

That is if you are chasing your losses (and at some point things may become quite intense and scary when you have hit a losing streak) you don’t have the bankroll to back it up.

For example, if your initial wager is £5 and you lose nine bets in a row, then you will have to stake £275 just to break even. If you were to then lose again, you would have to bet £445. If you don’t have the money to continue to fend off the losing streak, then you will be hit with heavy losses.

Designed by Leonardo Pisano, the Fibonacci system is a negative progression system that requires you to increase or decrease your stakes based on whether you win or lose a bet.

Just like all betting systems, the Fibonacci method can’t guarantee that you will beat the bookies in the long run. However, if done properly and with the right resources, it can certainly give you a much higher chance of success in the short term, provided all of necessary risks are taken into account.
