Paroli Betting Progression
Ride winning streaks with the reverse Martingale
The Paroli progression (also called the Reverse Martingale or Anti-Martingale) is a positive progression system that doubles bets after wins and resets after losses. Learn how this "let it ride" approach capitalizes on winning streaks while protecting your bankroll.
What is the Paroli Progression?
The Paroli is a positive progression where you double your bet after each win, aiming to capitalize on hot streaks. After a predetermined number of consecutive wins (typically 3), you reset to base bet to lock in profits.
Unlike Martingale which chases losses with ever-larger bets, Paroli only increases bets when you're winning - using the casino's money to potentially multiply your profits while risking only your original stake.
Key Principle
Double after wins, reset after losses
Let your winnings ride for 3 consecutive wins (1-2-4 units), then lock in profits and restart. Losses always return you to base bet.
How Paroli Works
Example: Successful 3-Win Streak ($5 base)
| Spin | Bet | Result | Round P/L | Total P/L | Next Bet |
|---|---|---|---|---|---|
| 1 | $5 | Win | +$5 | +$5 | $10 (x2) |
| 2 | $10 | Win | +$10 | +$15 | $20 (x2) |
| 3 | $20 | Win | +$20 | +$35 | $5 (reset!) |
| 4 | $5 | - | - | +$35 | - |
Result: 3 consecutive wins - $35 profit (7x base unit). Original risk: only $5.
Example: Interrupted Streak
| Spin | Bet | Result | Round P/L | Total P/L | Next Bet |
|---|---|---|---|---|---|
| 1 | $5 | Win | +$5 | +$5 | $10 |
| 2 | $10 | Loss | -$10 | -$5 | $5 (reset) |
| 3 | $5 | Loss | -$5 | -$10 | $5 (stay) |
Result: Streak interrupted on spin 2 - net loss of $10. But notice: max bet was only $10, not escalating like Martingale.
The Mathematics of Paroli
Probability Analysis (Red/Black, 48.6% win rate)
| Consecutive Wins | Probability | Profit (units) | Frequency |
|---|---|---|---|
| 0 (immediate loss) | 51.4% | -1 | ~1 in 2 |
| 1 win, then loss | 25.0% | -1 | ~1 in 4 |
| 2 wins, then loss | 12.1% | -1 | ~1 in 8 |
| 3 wins (complete!) | 11.5% | +7 | ~1 in 9 |
Expected Value Calculation
Per Paroli attempt:
- 88.5% chance: Lose 1 unit (streak breaks before 3 wins)
- 11.5% chance: Win 7 units (complete 3-win streak)
- EV: (0.885 x -1) + (0.115 x 7) = -0.08 units per attempt
Reality: Like all progressions, Paroli has negative expected value due to house edge. However, the variance is much lower than Martingale - no catastrophic losses.
Advantages and Disadvantages
- Limited downside: maximum loss per streak is 1 unit (base bet)
- Explosive upside: 7x profit on successful 3-win streak
- Uses "house money": after first win, you're betting winnings
- Never hits table limits: max bet is 4x base (easily under limits)
- Psychologically satisfying: riding streaks feels exciting
- Simple to execute: win = double, lose = reset, 3 wins = reset
- Small bankroll friendly: 10-15x base unit sufficient
- Frequent small losses: ~88% of attempts result in -1 unit
- Streak dependent: no profit without consecutive wins
- Slow profit accumulation: need ~1 completed streak per 8-9 attempts to break even
- Frustrating when cold: can feel like you're bleeding chips slowly
- Timing is everything: session may end before streaks appear
- House edge still applies: long-term expected value is negative
Paroli vs. Other Progressions
| Factor | Paroli | Martingale | Oscar's Grind | D'Alembert |
|---|---|---|---|---|
| Type | Positive | Negative | Positive | Negative |
| Max Loss/Attempt | 1 unit | 127+ units | ~10-15 units | ~50 units |
| Max Profit/Streak | 7 units | 1 unit | 1 unit | Variable |
| Bankroll Needed | 10-15x | 127x+ | 15-20x | 25-30x |
| Risk Profile | Low risk, high reward | High risk, low reward | Very low risk | Low-medium risk |
| Best For | Streak riders | Quick recovery | Patient grinders | Conservative play |
Implementing Paroli in SpinStrategy
Create a Paroli Progression
- Go to Dashboard - Progressions
- Click "New Progression"
- Select Sequence type
- Configure:
- Sequence: [1, 2, 4] (base, double, quadruple)
- Increase after consecutive wins: 1 (advance on each win)
- Reset after consecutive wins: 3 (lock profits after 3 wins)
- Reset after consecutive losses: 1 (reset immediately on loss)
- Create strategy:
- Bet Type: Red/Black, Odd/Even (even-money)
- Base Unit: 5-10% of session bankroll
See the Progressions documentation for how to configure sequence steps, or Strategies documentation for a full walkthrough.

Combining with Stop-Wins
Lock in session profits with triggers:
- Completed streak count: Exit after 3 completed streaks
- Profit threshold: Stop when up 20+ units
- Time limit: Cap sessions at 1 hour regardless of results
When NOT to Use Paroli
- Recovery mode: Don't use Paroli to chase losses from other strategies
- Cold tables: If you haven't won in 10+ spins, consider a break
- Tilting: Paroli requires patience - don't force streaks
Common Mistakes
- Not resetting after 3 wins: Greed kills profits - lock them in
- Chasing a 4th win: Probability drops to 6% - not worth the risk
- Increasing base bet after losses: Defeats the purpose of positive progression
- Expecting streaks every few spins: 3-win streaks occur ~11% of the time
- Using on low-probability bets: Paroli works best on even-money bets
Frequently Asked Questions
Why reset after 3 wins instead of continuing?
Three consecutive wins on even-money bets has only a 12% probability. Pushing for a 4th win drops to 6%. Resetting after 3 wins locks in 7 units profit before variance turns against you.
Is Paroli the opposite of Martingale?
Yes. Martingale doubles after losses (negative progression). Paroli doubles after wins (positive progression). Paroli has lower risk but also lower recovery potential.
Can I use Paroli on Dozens or Columns?
Yes, but adjust expectations. With 2:1 payouts and 32% win rate, consecutive wins are rarer. Consider resetting after 2 wins instead of 3.
What happens if I lose during a winning streak?
You lose only the current bet and reset to base unit. If you lose on spin 2 (betting 2 units), you've lost 1 unit net (won 1, lost 2). Much safer than negative progressions.
Conclusion
The Paroli progression is perfect for players who enjoy riding winning streaks without the catastrophic risk of negative progressions. It's exciting, low-risk, and mathematically elegant - though patience is required.
- Maximum loss per attempt is just 1 unit
- 7x profit potential on 3-win streaks
- Uses "house money" after first win
- Never hits table limits
- Simple and exciting to execute
- Requires 3 consecutive wins to profit
- ~88% of attempts result in -1 unit
- House edge still applies long-term
