Reverse Martingale (Paroli) Strategy for Roulette — UK Guide
The Reverse Martingale — a.k.a. Paroli — doubles after wins and
resets to your base stake after losses. It aims to press hot streaks while keeping cold streaks cheap.
Used well (with caps and discipline), it’s the most bankroll-friendly progression for even-money roulette.

How the Reverse Martingale Works
- Pick an even-money bet (Red/Black, Odd/Even, High/Low).
- Choose a base unit (e.g., £0.20, £0.50, £1).
- After a win: double your previous stake (press the win).
- After a loss: reset to the base unit.
- Cap the ladder after N wins (commonly 2–4), then bank profits and reset.
Popular Ladder Caps (Base = £1)
| Ladder | Stake Sequence | Profit if Completed | Largest Stake |
|---|---|---|---|
| 2-Step | £1 → £2 | +£3 | £2 |
| 3-Step (classic) | £1 → £2 → £4 | +£7 | £4 |
| 4-Step | £1 → £2 → £4 → £8 | +£15 | £8 |
If the ladder breaks (you lose before completion), the cycle ends at −1 base unit overall.
Why Paroli Is Bankroll-Friendly
- Your cash risk per cycle ≈ 1 base unit (you’re pressing with winnings).
- Table limits rarely bite — the largest stake is
base × 2N−1. - Short, capped ladders keep swings controlled while still giving a pop when streaks hit.
What Are the Chances Your Ladder Completes?
On European even-money bets, win probability per spin p = 18/37 ≈ 48.65%. For a capped ladder, completion = consecutive wins:
| Ladder | Probability | Approx. (1 in …) |
|---|---|---|
| 2-Step | p² ≈ 23.7% | ~4.2 |
| 3-Step | p³ ≈ 11.5% | ~8.7 |
| 4-Step | p⁴ ≈ 5.6% | ~17.8 |
Expected Value Snapshot (3-Step Paroli)
One cycle either completes (+7×base) or fails (−1×base). For European roulette:
- Completion chance: p³ ≈ 0.4865³ ≈ 0.115
- EV per cycle ≈ (0.115 × +7) + (0.885 × −1) = −0.078 × base (≈ −7.8% of base)
Paroli doesn’t beat the house edge; it just concentrates risk into brief “press” windows while keeping losses small per cycle.
Example — Base £0.50, 3-Step, Red
| Spin | Stake | Result | Cycle P/L |
|---|---|---|---|
| 1 | £0.50 | Win | +£0.50 |
| 2 | £1.00 | Win | +£1.50 |
| 3 | £2.00 | Win → bank | +£3.50 |
If you had lost on spin 2 or 3, the cycle ends −£0.50. Reset and start a new cycle.
Session Template (Bankroll Discipline)
- Base: £0.50 • Ladder: 3-Step • Bankroll: £50
- Profit target: +£10 (20 bases) • Stop-loss: −£10 (20 cycles)
- Table type: French (La Partage) or European single-zero
- Timer: 30–45 mins then break
Best Game Variants for Paroli
- French Roulette (La Partage/En Prison): even-money losses on 0 are halved/held → softens failed cycles.
- European Roulette: strong default; racetrack view helps quick re-bets.
- Avoid American: extra 00 drags value for even-money bets.
Live Dealer Tips
- Prefer low-limit live tables so your base fits comfortably.
- Hotkeys/quick re-bet if available; ladders need pace.
- On French live, confirm La Partage/En Prison is active in the info panel.
