Martingale: how to recover after losses
The best-known betting system: double after a loss, and the very first win covers the whole losing run. It sounds foolproof, but the simplicity hides one big risk — the strain on your bankroll. Here are the mechanics and the limits of where it works.
Martingale is popular for two reasons: you can explain it in a minute, and it lets you recover with a single win after a losing run of any length. But the simplicity has a price — here are the mechanics, the risk, and the point where the system breaks.
Martingale is one of the most popular roulette strategies for two reasons: its rules are easy to explain to a beginner, and it lets a single win recover a losing run of any length. The price for that is a huge strain on your bankroll when several losses land in a row.
The core principle: double after a loss, reset after a win
Say the base stake is $1. After a loss, you double the next bet — so the first win covers all the previous losses. Here’s how it looks on even-money bets paying 1:1:
| Bet and result | Balance | Action |
|---|---|---|
| $1 — loss | −$1 | Double |
| $2 — loss | −$3 | Double |
| $4 — loss | −$7 | Double |
| $8 — loss | −$15 | Double |
| $16 — win | +$1 | Run covered, reset |
After a win the player returns to the base stake ($1) and starts again. A detailed breakdown with charts is on the Martingale strategy page.
Martingale and high-risk bets
On even-money bets a win arrives roughly every other spin, and long losing runs are relatively rare. On bets with a chance below 48.6% you can use Martingale, but only with great care: a run can drag on, forcing you to raise the stake tens, hundreds, even thousands of times over. For straight-up bets, splits and streets it’s almost useless — either your bankroll or the table limit will run out first.
After ten losses in a row, the eleventh bet has to be 1,024 times the first.1 That’s exactly why an “infinite” Martingale doesn’t exist.
The verdict: how to use it
Martingale helps you recover, but it promises no real profit: a big win only covers the losses, leaving you up by a single unit. Set your bankroll and base stake so you have headroom to raise the stake hundreds of times over — otherwise you won’t survive a losing run. You can run the system over 1,000 spins and see its breaking point in our strategy tester.

2¹⁰ = 1,024. The doubling progression grows by powers of two, so each new loss nearly doubles the total risk of the run. ↩
