The Fibonacci betting system is based on one of the world’s most important mathematical discoveries and traces its roots back to the Middle Ages. It’s a cancellation system that follows a sequence of numbers and it should, theoretically, make you a profit in the long run.

The Fibonacci strategy is a negative progression system that’s been built on Fibonacci’s famous number sequence. It’s been around for over 7 centuries, and we’ll discuss whether it’s worth using it in today’s day and age, and whether you can make a profit with it.

The Fibonacci Sequence

The Fibonacci sequence is one of the most fascinating mathematical theories. It dates back to the early 13th century, courtesy of the Italian mathematician Leonardo of Pisa. The sequence got its name from Leonardo’s nickname, Fibonacci.

The sequence is a series where each number is the sum of the two before it, starting with 0 and 1. While this might not seem fascinating to you at first, once you get to know it better, you will quickly realize that it shows the natural rhythm woven into the fabric of the universe.

Fibonacci discovered that if you divide any number after number 5 on the sequence with the previous number, you get the same result: 1.618. That’s a number called the golden ratio and is represented in mathematics by the letter Φ. What’s interesting is that this ratio is found everywhere in nature, so bettors thought it could be useful for sports betting too.

Let’s take a look at the Fibonacci formula: N3 = N1 + N2

Based on this formula, starting from 0, each number in the Fibonacci sequence is the sum of the two preceding ones. Hence, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, and so on.

Fibonacci

From the arrangement of leaves around a stem to the number of spirals in the head of a sunflower, they all follow this sequence. What’s more, it’s found in our own anatomy too, and the most important artefacts in human history follow the Fibonacci sequence. Judging by that, it would be a shock if someone did not try to make a betting system out of it.

The Fibonacci Betting System Explained

To use the Fibonacci betting system, you must follow its two fundamental principles. When you lose a bet, you move one number up (right) on the Fibonacci sequence and bet that number of units. When you win a bet, move two numbers down (left) the sequence and bet that number of units.

Seeing an example will make this a lot easier to understand.

To keep things simple, imagine your base unit is £10. Now, with a unit size of £10, according to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34,55…), your bets will look like this:

£10, £10, £20, £30, £50, £80, £130, £210, £340, £550 and so on.

While the Fibonacci system might work reasonably well in casino games with fixed odds, sports betting is an entirely different ball game. Unlike betting on black or red in roulette, sports betting is synonymous with unpredictable outcomes influenced by countless variables beyond mere probability.

Fibonacci Betting System: Sports Betting Example

Unlike fish and chips, the Fibonacci and sports betting are not quite a match made in heaven. The system can bring far more success when betting on even-money casino games. This explains why it was once heavily embraced by the roulette-loving community.​

To have at least some success with the Fibonacci betting system when betting on sports, you must stick with selections with odds like 1/1, 10/11, 11/10, and 6/5. However, selections with such odds do not come by very often.

To show you how the Fibonacci Betting system works when betting on sports, we will look at a hypothetical scenario in which a bettor follows the Fibonacci system 15 times, betting on selections with odds ranging from 9/10 to 13/10.

15£3013/10Loss/+£5.00+£5.00

Although, in our scenario, the punter finishes with a positive balance, it is crucial to understand that this does not reflect how things would play out in real life. This is a speculative example where we have not factored in the margin charged by every bookie.

Pros & Cons of this Betting System

Although theoretically sound, the Fibonacci betting system is still flawed, especially when using it to bet on sports. However, as with anything else, there are always two sides to every coin. Because of that, we will look at both the pros and cons of the Fibonacci system for sports betting.

Pros:

  • Easy to understand and follow
  • You can start it with a small bet
  • Works well with various casino games

Cons:

  • Not particularly suited for sports betting
  • Gives a false sense of security
  • It does not have a specified endpoint
  • Requires a high volume of bets
  • Requires a sizable bankroll so you can handle long losing streaks
  • You risk facing betting limits by the bookmakers
  • It can be time-consuming, as you must wait for each bet to be settled before moving on to the next one

Does The Fibonacci Betting System Guarantee Profit?

The general idea of the Fibonacci betting system is that by following the sequence, no matter how often you lose, you will eventually recover your losses and make a profit. Theoretically speaking, that is 100% true. In practice, though? Not so much.

To be successful with the Fibonacci betting system consistently, you would need an unlimited bankroll and a bookmaker willing to accept all your bets without imposing any limits on your account.

Blindly following the Fibonacci betting system can swiftly drain your bankroll and make you overconfident or reckless. Leaning too heavily on this strategy might give you a false sense of invincibility. This can lead to hefty financial losses that will take a toll not only on your wallet but on your mental health too. Our suggestion would be to only try this system with even-money casino games, and avoid it for sports betting.
