Fibonacci Roulette Strategy Explained: The Ultimate Guide for Beginners

Casino Roulette game scene
Simon Young

September 24th, 2025

The simplicity of roulette makes it an accessible table game for all players, but the depth of the game keeps many coming back. While roulette is ultimately based on chance, many folks use specific betting strategies to help them manage their bankroll and stay in control.

One such method is the Fibonacci roulette strategy, which follows the pattern of the Fibonacci sequence to determine play. Based on a famous mathematical sequence, this approach offers a structured way to recover losses and build momentum without the high risk of more aggressive systems like Martingale.

Here, we explain how the Fibonacci strategy works, who it’s best suited for, and how it holds up against other popular roulette systems.

What is the Fibonacci Strategy?

The Fibonacci strategy is a negative progression system, meaning you increase your bet after a loss, rather than a win. It’s based on the Fibonacci sequence, a series of numbers where each number is the sum of the two before it, as follows:

1, 1, 2, 3, 5, 8, 13, 21...

This sequence determines your bet size in roulette based on the outcome of the previous round. You start with the first number (1 unit), and move one step forward in the sequence each time you lose, and two steps back when you win. The theory with this progression is that you will eventually recover any previous losses with future wins.

What makes Fibonacci so popular is its easy-to-follow and less aggressive nature compared with strategies like Martingale. It’s ideally suited to even-money bets with a 1:1 payout, making it a great entry point if you’re looking for structure without high volatility.

Call 1-877-8-HOPENY or text HOPENY (467369) (NY).

Implementing the Fibonacci Strategy

The first step is picking your starting wager or unit, as this will be the foundation for all subsequent plays. For example, if you were to begin with a $10 wager, your game could play out something like this: 

  • First bet: $10. Outcome: lose.
  • Second bet: $10. Outcome: lose.
  • Third bet: $20. Outcome: lose.
  • Fourth bet: $30. Outcome: win.
  • Fifth bet: $10…

Fibonacci Roulette Strategy: Pros & Cons

As with any betting strategy, Fibonacci is not without risks and does not guarantee a positive outcome. Instead, it’s a way of adding structure to your gameplay that won’t blow your budget.

In the table below, we have highlighted the main pros and cons of using the Fibonacci roulette strategy: 

ProsCons
✅ Easy to learn and apply❌ Only suits even-money bets
✅ Can help recover losses gradually❌ Can lead to large bets after multiple losses
✅ Moderate risk level❌ Requires tracking and patience
✅ Structure encourages disciplined play

Fibonacci vs Other Roulette Strategies

Not all roulette strategies are suited to everyone. While the Fibonacci strategy is relatively accessible to most players, being a mid-level risk method, others, like Martingale, require more aggressive gambling and are not for the faint-hearted.

In contrast to Fibonacci's medium risk level, the Martingale strategy is highly aggressive. You double your bet after every loss, aiming to recover all previous losses with a single win. While effective in short bursts, this strategy demands a large bankroll and can quickly hit table limits or smash through your budget.

The D’Alembert system is more conservative and is a great option for beginners or casual players looking to make their budget last for a more extended gaming session. You increase your bet by one predetermined unit after a loss and decrease it by one after a win. It’s a slower progression, which means it’s slower to recover losses, but easier to manage over time.

The Paroli strategy is another great option. This time, it takes the opposite approach with a positive progression. Following each win, when using Paroli, you double your bet to lock in profits during winning streaks. Again, it is less risky than Martingale, but it does rely on consecutive wins to garner the best results.
