This is an editorial guide provided for information only. The figures below come from a genuine computer simulation of a standard European single-zero roulette wheel: even-money bets, a £100 bankroll, a £1 base stake and 200-spin sessions, one million sessions per system. Real tables vary in rules and limits, and no betting system changes the house edge. fortunegames.com game availability can change at any time.
The Fibonacci Roulette System, Simulated 1 Million Times
The Fibonacci system is the Martingale’s gentler cousin: instead of doubling after a loss, you climb the famous sequence — 1, 1, 2, 3, 5, 8, 13, 21 — and step back two numbers after a win. We gave it one million simulated sessions, and it produced the strangest result in our lab: 56.9% of players finished ahead, the best of six systems tested — while still losing exactly 2.7% of every pound staked.
How the ladder works
Each loss moves you one step up the sequence; each win moves you two steps down. Because a win at any rung repays the previous two bets, steady progress back down the ladder claws losses back gradually rather than in one violent double. Bets grow far more slowly than Martingale’s — after nine straight losses you’re staking £55, not £512.
What a million sessions showed
With £100 bankrolls and £1 base bets over 200-spin sessions, the median Fibonacci player finished £25 up, and sessions survived an average of 156 spins — far longer than Martingale’s 109. The bill arrived at the other end of the distribution: 42.3% of sessions eventually hit a run the ladder couldn’t climb and ended at or near a £100 wipeout. Many pleasant evenings, occasionally paid for by a dreadful one.
The catch, in one sentence
Fibonacci doesn’t shrink roulette’s cost — our players lost the same 2.70% of turnover as flat bettors, Martingale users and everyone else — it just moves the losses into rarer, larger piles while spreading small wins across most nights. The mean result across all million sessions was minus £10.32, positive medians notwithstanding.
Fibonacci vs Martingale
Against its famous cousin, Fibonacci is genuinely the kinder ladder: slower bet growth, nearly 50% longer survival, and almost double the share of winning sessions. But “kinder ladder” is the whole prize — the destination is identical, and the wipeouts, when they come, take everything just the same. Treat it as a way to pace an evening, never as a way to win one.
Frequently asked questions
Does the Fibonacci system work at roulette?
It produced winning sessions 56.9% of the time in our simulation — and still lost the full 2.7% house edge on all money staked. It reshapes results; it doesn’t beat them.
How do the bets progress?
One step up the sequence (1, 1, 2, 3, 5, 8, 13…) after a loss, two steps back after a win — reaching £55 after nine straight losses.
Is Fibonacci safer than Martingale?
Gentler, yes — slower bet growth and longer sessions — but 42.3% of our simulated sessions still ended in a wipeout, and the expected loss is identical.
Are these real results?
Yes — one million seeded 200-spin sessions on an exact European single-zero wheel model, with the full setup stated at the top of the page.
