What is the Fibonacci Roulette System?

fibonacci roulette sequence

The Fibonacci Roulette System is a negative progression strategy in which you increase your bets after a loss along a Fibonacci sequence (1,1,2,3,5,8…etc or multiples thereof).

The idea is to claw back any losses, but in a less aggressive and risky way than you would do on a Martingale, in which you double your bet after a loss. The upside is that the betting profile is less steep. The downside is that you will only claw back a percentage of your previous win.

In both cases, the aim is to get onto a winning streak and flat bet your way into profit.

The Fibonacci roulette system was developed from a mathematical sequence (discovered by Leonardo Fibonacci in 1202).

This mathematical equation describes the shape of many naturally occurring objects and phenomena including the shape of the shell to the left. (The Reverse Fibonacci also uses this of course).

For hundreds of years, this sequence has been used to try and beat the roulette wheel. It’s also a favourite of baccarat players and forex traders.

Sequence of Bets

The Fibonacci is similar to The Martingale, in that you increase your bets after a loss to try and claw back losses. It’s one of several negative progression systems (another is the Labouchere system). The difference being that the Fibonacci is less aggressive than the Martingale.

Instead of doubling your bets like you do in the Martingale after a loss, in the Fibonacci your bet after a loss equals the sum of the two previous bets.

(Another even less aggressive negative progression is the D’Alembert System).

A regressive roulette system, on the other hand, focuses on increasing bets after a win, and then lowering your bets now and then, to bank profits,

So say you begin with a single unit bet. Your sequence on a losing streak would be as follows:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144
If you started with a 5.00 bet, your sequence would be
5, 5, 10, 15, 25, 40, 65, 105, 170, etc

You can see that your bets ramp up if you hit a bad patch, but not as fast as they would with the Martingale.

Fibonacci Roulette Tips

If you want to play this more aggressively, just set your initial bet higher. So, for example, instead of a standard sequence of 1,1,2,3,5,8,13 etc, you could go 5,5,10,15,25, etc. Just remember, the higher the starting number, the quicker you will hit the table betting limits if you do hit a losing streak, so be careful.

Fibonacci System vs the Martingale System

In the Martingale, you revert to your initial bet after a win. In the Fibonacci, you go back two numbers, so in the 5.00 example above, if we won on our 65.00 bet, our next bet would be 2.00. If we won that one, the following bet would be 10.00 and so on. If you can keep winning and get back to your initial bet, then you are all square overall, and it’s time to try and get into the black again.

The idea is to bring yourself back into profit steadily. Whereas, in The Martingale, you aim to cancel out all of your previous losses with one big win (so you sometimes end up betting big to win a small amount), in the Fibonacci, you aim to cancel out only your previous 2 losses. It’s still a negative progression system, so be careful, but it’s less aggressive.

Although a progressive gambling system, the Fibonacci differs from the Martingale system in that it doesn’t seek to cancel out the total loss with one win, just the last two losing bets.

The best thing to do is to have a pad of paper next to you and write it out as you go. This is a medium-risk system. It doesn’t change your odds at the table, but may be worth testing as a money management strategy.
Remember, as with all systems, set yourself a strict stop loss and profit target before you play. Good luck!

Pros and Cons

  • Less aggressive than the Martingale.
  • Relatively easy to use- just write your sequence down on a pad.
  • You can play it on any bet, although most people use it on the high table coverage bets like red/black or dozens.
  • You still need to watch it! Your bets can increase quickly if you are not having a lucky day.
  • The system only wipes out the last two losses. You may need to win again to claw back all of your losses
  • The Fibonacci does not change your odds: 2.6% in European Roulette.
  • It’s a negative progression- so you flat bet after a win. If your starting bet is low, it can be slow work to eke out a sizeable profit.

Remember- set your Stop-Loss and Take-Profit levels and stick to them! Don’t be greedy.

Questions, Answers

  • How do you Use the Fibonacci Sequence in roulette?
    The Fibonacci is a handy way of mapping out a less aggressive negative progression (increased bets after a loss). You see this sequence a lot in nature and it is also used extensively to mark retracement levels in forex trading, so there is probably a bit of superstition involved as well with system players.
  • How long should you play the sequence?
    Like any negative progression, if you get a sequence of losses you are going to go deeper and deeper into the red. So it is important that you set out a limit before you use this system – don´t chase your losses. Before you start, work out a level of loss you are comfortable with and rigidly stick to this level: don´t go beyond it. Forex traders do this the whole time, it´s called a Stop Loss.
  • Does the Fibonacci System Guarantee Wins?
    No. There is no such thing as a “Guaranteed Win” in roulette. It’s a game of chance and the House has the edge. This system tries to claw back any losses. It will work for stretches of time, but not consistently.
