Reverse Martingale (Paroli) betting flow
Paroli doubles on wins, resets on losses — pressing streaks with a capped ladder.

How the Reverse Martingale Works

  1. Pick an even-money bet (Red/Black, Odd/Even, High/Low).
  2. Choose a base unit (e.g., £0.20, £0.50, £1).
  3. After a win: double your previous stake (press the win).
  4. After a loss: reset to the base unit.
  5. Cap the ladder after N wins (commonly 2–4), then bank profits and reset.
Best tables: French roulette with La Partage or En Prison (even-money edge ~1.35%), then European single-zero (2.70%). Avoid American 0/00 (5.26%).

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
Reality check: Ladders complete less often as you add steps. Most pros cap at 3 or 4 wins, then bank.

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.
