| Updated: September 26, 2025Luck is an integral element of most casino games. When it comes to roulette, effective bankroll management is essential. Because roulette relies on chance, players can only try to minimize their losses. Over the years, casino enthusiasts have devised numerous roulette strategies in an effort to tilt the odds in their favor. To date, no betting system guarantees success; however, some can be profitable in the short term.
One well-known roulette strategy is the Fibonacci system. As the name implies, it is based on the Fibonacci sequence. This sequence has applications in many areas of life, including mathematics, computer science, and nature. The Fibonacci sequence has also inspired casino aficionados, who have adapted it for use at the roulette table.

Applying the Fibonacci Strategy to Roulette
The Base Stake

The most confusing part of the Fibonacci strategy is determining the size of your stake. First, set the size of your opening wager. Experienced players claim that the optimal bet is 1% to 2% of your bankroll. If you are using the strategy for the first time, start with the lowest bet the roulette table allows. This approach will also keep you from hitting the maximum table limits too quickly.
Follow the Sequence
The first bet in your betting cycle is one unit, which corresponds to the first number in the sequence. For example, if your opening wager is $20, then the sequence will be as follows: $20, $20, $40, $60, $100, $160, $260, and so on. You must follow the sequence and increase your bet every time you lose. Whenever you win, move back two numbers. In a nutshell, the Fibonacci roulette strategy is based on the following rules:
- Move one number up the sequence whenever a loss occurs
- Move two numbers down the sequence after a win
Look at the example below to better understand the concept behind the Fibonacci strategy:
| Bet Number | Bet Size | Outcome | Net Profits |
|---|---|---|---|
| 1 | 20 | Lose | -20 |
| 2 | 20 | Lose | -40 |
| 3 | 40 | Lose | -80 |
| 4 | 60 | Win | -20 |
| 5 | 20 | Win | 0 |
| 6 | 20 | Win | 20 |
The Idea Behind the Fibonacci System
For many novice casino enthusiasts, negative progression roulette systems simply do not make sense. Yet we would not discuss them if they offered no benefit at all. The Fibonacci betting system gives players a chance to recoup losses after just a few wins.
Even after a long losing streak, you might be able to recover quickly. Still, the system carries risk because you never know when the losing streak will end or whether you will have enough money left to continue.
Ending the Progression
Once you make a profit in the current betting cycle, you should end the progression. Much of the strategy’s complexity arises from the need for players to track how much they have won and lost to know when to return to the start of the sequence.
Winning the first bet is the best possible outcome for those using the Fibonacci system. However, if you also win the second and third bets, you will break even and must begin the progression again.
Inside or Outside Bets?
Roulette enthusiasts can apply the Fibonacci strategy to inside bets, but it is primarily designed for even-money outside bets. These bets offer nearly a fifty-fifty chance of winning and pay 1:1. In roulette, the even-money bets are Red/Black, High/Low, and Odd/Even.
If you are wondering why the Fibonacci strategy is not suitable for inside bets, the answer is that the chance of winning an inside bet is lower. Consequently, you are more likely to lose and will need to increase your stakes very quickly.
Useful Tips
Adjusting bet sizes while moving up and down the sequence can be confusing for novice roulette enthusiasts. To simplify matters, write the sequence on a piece of paper and record only the outcome of each spin.
Loss Limits
Roulette betting strategies, including the Fibonacci, can cost casino enthusiasts a fortune if they do not know when to stop. To keep from losing your hard-earned money in a flash, set firm loss limits. Many experts suggest ending the Fibonacci progression after six or seven consecutive losses. Chasing losses is risky and can lead to gambling problems.
