The Sequence
Fibonacci's progression: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89… Each number is the sum of the two before it. In roulette, each number is a multiple of your base unit — for a $1 base, the first stakes are $1, $1, $2, $3, $5, $8, and so on.
The Rules
- Bet on an even-money outcome (red/black, odd/even, high/low).
- After a loss: move one step forward in the sequence.
- After a win: move two steps backward.
- Reach the start of the sequence and you've locked in a profit.
Worked Example
$1 base, sequence 1-1-2-3-5-8…
- Bet $1 — lose. (−$1)
- Bet $1 — lose. (−$2)
- Bet $2 — lose. (−$4)
- Bet $3 — lose. (−$7)
- Bet $5 — win. (−$2). Move two steps back to $2.
- Bet $2 — win. (Even). Move back to $1.
Why It's Gentler Than Martingale
Stakes grow linearly, not exponentially. Eight losses on Fibonacci have you betting $34. Eight losses on Martingale have you betting $256. The slower climb means a smaller bankroll lasts longer, and table limits are far less likely to interfere.
Where It Falls Short
The flatter curve cuts both ways. When you finally win, you don't always erase the entire deficit in one spin — you have to climb back down with multiple wins. Long unbalanced sessions can still drain a bankroll, just more slowly.
Try It in the Simulator
Open the free roulette table and run 50 spins on red with a base unit of $1. Track when you reach step 1 again — that's a complete cycle. Most cycles end in a small profit; rare ones end with a bruise.
