Fibonacci Strategy
The Fibonacci Strategy is a betting system based on the famous Fibonacci sequence.
The sequence is created by adding the two previous numbers together:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55...
In roulette, players use these numbers as betting units.
The strategy is classified as a negative progression system because bets increase after losses.
## How the Fibonacci Strategy Works
Choose a base betting unit.
Example:
Unit size: €10
The progression becomes:
€10, €10, €20, €30, €50, €80, €130...
Rules:
- After a loss, move one step forward in the sequence.
- After a win, move two steps backward in the sequence.
- Return to the beginning whenever possible.
Example Session:
Spin 1:
Bet €10 → Lose
Spin 2:
Bet €10 → Lose
Spin 3:
Bet €20 → Lose
Spin 4:
Bet €30 → Win
After the win, move back two positions in the sequence.
Next bet:
€10
The strategy attempts to recover losses gradually rather than aggressively.
## Advantages
- Slower progression than Martingale
- Lower bankroll requirements
- Less vulnerable to table limits
- Simple mathematical structure
## Disadvantages
- Long losing streaks still create large bets
- Recovery can take time
- Bankroll depletion remains possible
- Does not eliminate the house edge
## Why Players Like Fibonacci
Many players prefer Fibonacci because the progression feels more controlled than Martingale.
Instead of doubling after every loss, bet increases are gradual.
This creates a smoother betting curve and reduces the speed at which stakes escalate.
## Mathematical Reality
The Fibonacci sequence changes only bet sizing.
It does not influence roulette outcomes.
Every spin remains independent.
The house edge remains:
- European Roulette: 2.70%
- American Roulette: 5.26%
No betting progression can change the mathematical expectation of the game.
## Example Progression
Unit Size: €10
Sequence:
€10
€10
€20
€30
€50
€80
€130
€210
€340
Even though growth is slower than Martingale, extended losing streaks can still produce very large wagers.
## Fibonacci vs Martingale
Martingale:
- Double after losses
- Rapid growth
- High bankroll requirement
Fibonacci:
- Follow Fibonacci sequence
- Slower growth
- Lower bankroll requirement
Both systems rely on eventually obtaining winning spins.
Neither system removes the house edge.
## Responsible Gambling Considerations
The Fibonacci Strategy often appears safer because bets increase more slowly.
However, prolonged losing streaks can still result in substantial losses.
Players should always set bankroll limits and avoid increasing the base unit to recover previous losses.
