Pros
The main advantage of using the Paroli 1-3-7 Betting System in roulette is that even after 10 consecutive losses, three wins in a row puts you in profit.
Even After 10 Losses, Three Wins in a Row Puts You in Profit
Roulette runs in streaks — betting on red, a 10-loss streak is entirely possible. But with the Paroli 1-3-7 Betting System, when the turn finally comes, you can cash out the comeback.
Example: 3 Wins After 10 Losses
| Bet Amount | Win/Loss | Payout | Balance | |
|---|---|---|---|---|
| Round 1 | $1 | Loss | 0 | -$1 |
| Round 2 | $1 | Loss | 0 | -$2 |
| Round 3 | $1 | Loss | 0 | -$3 |
| Round 4 | $1 | Loss | 0 | -$4 |
| Round 5 | $1 | Loss | 0 | -$5 |
| Round 6 | $1 | Loss | 0 | -$6 |
| Round 7 | $1 | Loss | 0 | -$7 |
| Round 8 | $1 | Loss | 0 | -$8 |
| Round 9 | $1 | Loss | 0 | -$9 |
| Round 10 | $1 | Loss | 0 | -$10 |
| Round 11 | $1 | Win | $2 | -$9 |
| Round 12 | $3 | Win | $6 | -$6 |
| Round 13 | $7 | Win | $14 | $1 |
↑ If it actually played out that way, that’s one satisfying comeback.
Cons
The main downside of using the Paroli 1-3-7 Betting System in roulette is that you can’t profit without a winning streak.
You Can’t Profit Without a Winning Streak
When results are alternating or you just can’t string wins together, it’s better to stop mid-session.
That’s what I do.
The Paroli is a method for keeping risk low while building gains incrementally — if the table isn’t giving you that, walking away is the right call.
At the end of the day, if you can’t read those situations and act on them, staying ahead in roulette is a tough ask.
