Reverse Martingale (Paroli)

Press winners, not losers — ride short hot streaks on even money.

Best for: Players who want limited downside while trying to capitalize on short winning runs

Overview

Reverse Martingale (often called Paroli) flips the classic approach: you raise the stake after wins and return to the base unit after a loss. Losses stay capped near one unit; profits depend on catching consecutive hits.

Most players pre-define a win streak length — commonly three wins — then pocket the profit and restart. That stop rule is the difference between a controlled press and giving everything back.

Like every other system, Paroli does not change probabilities. It redistributes variance: smaller average losses, larger occasional multi-unit wins when streaks appear.

How it works

  1. Pick a base unit and an even-money bet type.
  2. Bet one unit. On a loss, stay at one unit (or step back if you had pressed).
  3. On a win, double (or otherwise increase) for the next spin using house money.
  4. After a preset number of consecutive wins (often 3), reset to one unit and bank the surplus.
  5. Never chase a loss by escalating — that would turn Paroli back into Martingale.

Three-win Paroli cycle (base $10)

  1. Bet $10 — win. Next stake $20.
  2. Bet $20 — win. Next stake $40.
  3. Bet $40 — win. Cycle complete: book profit and return to $10.
  4. If any spin loses mid-cycle, drop back to $10 immediately.

Pros

  • Downside per losing spin is usually one base unit
  • Uses winning streaks rather than digging out of holes
  • Natural session stop rules (e.g., three wins)

Cons

  • Most sessions produce many one-unit losses between rare multi-win runs
  • Easy to over-press without a hard streak limit
  • Still faces house edge on every spin

FAQ

Is Paroli safer than Martingale?

Typically yes for bankroll drawdowns, because you are not doubling into a losing streak. “Safer” does not mean profitable long-term.

What streak length should I use?

Three wins is a common educational default. Longer presses increase upside and the chance of giving back the run.
