How to Use the Fibonacci Strategy for Roulette

The Fibonacci System is a roulette strategy that encourages you to increase your bet amount each time you lose.

It seeks to wipe out previous losses when you eventually land a big win. There are some clear pros and cons to this approach, as we have outlined below.

What is the Fibonacci sequence?

Leonardo Bonacci of Pisa, who went by the name of Fibonacci, was regarded as the most gifted mathematician of the Middle Ages. His most famous creation is the Fibonacci sequence, which is still widely used to this day.

He created it to calculate the growth of rabbit populations, but it can be applied to all walks of life. The algebra underpinning the formula looks quite complex, but all you need to know is that each number is the sum of the two preceding numbers.

That means the Fibonacci System looks like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, and so on.

How does the Fibonacci strategy work in roulette?

You can use the Fibonacci sequence betting system for playing real money roulette. The idea behind the system is to move one step forward each time you lose and two steps back whenever you win.

First, you need to determine your base unit. This is a percentage of your bankroll. You then start by wagering 1 unit.

If you lose, you follow the sequence. Wager 1 unit, then 2 units, then 3 units, then 5 units, and so on. When you win, go back two steps in the chain.


Let’s say you have $1,000 to play roulette, and you decide to make your base unit 1% of that bankroll. You would then begin the Fibonacci System by wagering $10.

This is how a roulette session might unfold if you follow the Fibonacci sequence.

Bet AmountOutcomeProfit / Loss

In this hypothetical example, the player wins just five of 12 spins but ends with a modest profit. Even though they were down $120 at one point, use of the system resulted in a small $10 profit in the end.

However, this roulette betting strategy often fails to claw back previous losses, and it does not capitalize on winning streaks either, so it is by no means a foolproof approach.

The Fibonacci System is a negative progression strategy that can be used on any bets that pay 1:1. If you are playing roulette, that can apply to red/black, odd/even, or high/low wagers. Since these are present with every type of roulette, you can use the Fibonacci for online casino games (including live dealer roulette) and in person.

Most players stick to one particular bet—for example, bet red on every spin—but you can mix it up if you like. In fact, it’s nice to play around with it a bit, which you can do with free roulette casinos, including Golden Nugget Casino, Caesars, BetMGM Casino, and DraftKings Casino.

Advantages of using the Fibonacci sequence

  • The Fibonacci roulette system adds a certain degree of rigor to your roulette play, instructing you how much to bet on each spin.
  • It appeals to players who like the idea of chasing down losses.
  • The Fibonacci is less aggressive than the Martingale System, and it is less likely to run up against table limits.
  • When the Fibonacci succeeds, you can win fewer than half your bets and still end up with a small profit.

Disadvantages of the Fibonacci sequence

  • The Fibonacci roulette system is slightly more complex than some alternative approaches.
  • It is not as aggressive as some approaches, but you need a large bankroll, big table limits, and a high tolerance for risk.
  • The system does not capitalize on winning streaks, which can be frustrating for some players.
  • It cannot cut out the house edge built into roulette games, and it often fails to make up for previous losses.

Other Roulette Betting Systems

The Fibonacci System is not the only system for structuring your wagers on roulette. There are several other strategies you can employ to insert a bit of order into the chaos.

It may, as the Fibonacci roulette strategy can help bring structure to your sessions. No system can influence the result of the roulette wheel, however.

The Fibonacci is less aggressive than alternative approaches, such as the Martingale, but it can still require you to place very large wagers after a losing streak. As such, it is a relatively high-risk approach, so you might like to try it out in demo mode before playing for real money.

Absolutely. However, you will potentially need a large bankroll and a roulette table with high limits. And as always, this system does not guarantee success.

This betting system is named after the Fibonacci sequence, in which each number is equal to the sum of the two previous numbers. That sequence owes its name to its creator, a 13th-century Italian mathematician.

The Fibonacci sequence may appeal if you like the idea of clawing back previous losses with a big win. However, no betting system will guarantee winnings, and the Fibonacci is also a reasonably risky approach, so it will not be for everyone.
