The Fibonacci strategy for crash games is simple: move one step up the 1-1-2-3-5-8 sequence after a loss and two steps back after a win. You keep the same auto cash out, usually 2x, and only change how much you stake. It climbs slower than Martingale, and one win wipes out two steps of the sequence. Examples use a KSh 100 unit. Part of our crash game strategy guide.
How Fibonacci works
Rule: move one step up the 1-1-2-3-5-8 sequence after a loss and two steps back after a win. A quick run with a 2x target:
KSh 100 loses → KSh 100 loses → KSh 200 loses → KSh 300 wins → KSh 100
Your win chance stays 48.5% at 2x every round; the system only changes your stake sizes. Compare it with the classic progressions in the D’Alembert and Fibonacci guide.
Simulator results
Fibonacci at a 2x auto cash out, KSh 5,000 budget (KSh 100 unit), 100 rounds, 1,000 sessions:
| System | Typical end | Middle 80% | Ran out |
|---|---|---|---|
| Fibonacci | KSh 6,300 | KSh 0–KSh 7,400 | 31.5% |
| Flat bets | KSh 4,800 | KSh 3,600–KSh 6,000 | 0% |
| Martingale | KSh 4,600 | KSh 0–KSh 10,200 | 46.5% |
Fibonacci changes the shape of your sessions: wider swings both ways. Run your own version in the crash strategy simulator.
Fibonacci vs Martingale and Anti-Martingale
The Martingale strategy doubles after every loss, so one win recovers everything but a long cold run gets expensive fast. The Anti-Martingale strategy presses after wins instead. Fibonacci sits in between, with smaller steps. Still deciding? Our best betting system for crash games guide ranks them all.
Playing betting systems in Kenya
Kenyan pilots run this plan the same way on Betika, SportPesa, Odibets or a partner casino, because the maths is identical everywhere. Top up with M-Pesa (steps in our Aviator M-Pesa guide), keep stakes in round shillings such as KSh 50, KSh 100 or KSh 200 so tracking is easy, and treat rain free bets as a bonus on top of your budget, not part of it. More local tips in the Betika Aviator guide.
Best games for Fibonacci
Any crash game with auto cash out works. The Aviator game and the JetX game are favourites in Kenya; at our partner casinos you can also try Stake’s own crash original.
Pro tip: write your stake sequence down before the session. Fibonacci works best when you never improvise mid-run.

| Strategy | Median final bankroll | Unlucky (10th percentile) | Lucky (90th percentile) | Chance of going bust |
|---|---|---|---|---|
| Fibonacci | Ksh 6,300 | Ksh 0 | Ksh 7,400 | 31.5% |
| Fixed bet | Ksh 4,800 | Ksh 3,600 | Ksh 6,000 | 0.0% |

Frequently asked questions
What is the Fibonacci strategy?
A betting system for crash games: move one step up the 1-1-2-3-5-8 sequence after a loss and two steps back after a win.
Does Fibonacci work in Aviator?
Yes, as a way to size bets. Your win chance at 2x stays about 48.5% every round; Fibonacci only changes stakes.
Is Fibonacci better than Martingale?
It is calmer: in our simulation 31.5% of Fibonacci sessions ran out of budget against 46.5% for Martingale.
What auto cash out should I use with Fibonacci?
2x is the classic choice because one win roughly covers one losing stake.
How much budget do I need for Fibonacci?
At least 50 units, for example KSh 5,000 with a KSh 100 unit.
Can any betting system beat a crash game?
No system changes the RTP. Systems change how your session feels and how big the swings are.
