Martingale Strategy
Double after every loss on even-money bets — classic recovery chase.
Best for: Short sessions on even-money bets with a large bankroll cushion
Overview
Martingale is the most famous progressive roulette system. After each losing spin on an even-money bet (red/black, odd/even, 1–18/19–36), you double the stake. After a win, you return to the base unit.
The idea feels intuitive: one win recovers all previous losses in the sequence plus one unit of profit. In practice, long losing streaks grow stakes exponentially until table limits or bankroll stop you.
No progression changes the mathematical house edge. On standard European single-zero roulette, even-money bets still carry about 2.70% house edge (roughly 1.35% only when French La Partage/En Prison applies); American double-zero wheels are harsher at about 5.26%.

How it works
- Choose a base unit small enough that several doubles still fit under the table maximum (for example $1–$5 if the max is a few hundred).
- Place an even-money bet for one unit. If it wins, bank the profit and keep betting one unit.
- If it loses, bet two units on the same type of bet. Continue doubling after each loss: 1 → 2 → 4 → 8 → 16 → 32…
- When a spin finally wins, the payout equals the sum of prior losses in that run plus one unit. Reset to the base unit.
- Stop conditions matter more than the formula: set a hard bankroll cap and respect table maximums before you start.
Example sequence (base unit $5, European wheel, red)
- Spin 1: bet $5 on red — lose. Running loss $5.
- Spin 2: bet $10 on red — lose. Running loss $15.
- Spin 3: bet $20 on red — lose. Running loss $35.
- Spin 4: bet $40 on red — win $40. Net for the sequence: +$5.
- Next spin restarts at $5. One more long losing streak can demand $80, $160, $320…
Pros
- Simple rules that are easy to execute under pressure
- Frequent small “session wins” when streaks stay short
- Works only with even-money bets that pay 1:1
Cons
- Exponential stake growth after consecutive losses
- Table maximums can freeze the progression mid-drawdown
- Requires a bankroll far larger than the target profit
- Does not overcome house edge or zero/double-zero outcomes
FAQ
Does Martingale guarantee a profit?
No. It only recovers a finished losing run if you can still place the next doubled bet. Limits, depleted funds, or a long streak end the system at a large loss.
Is Martingale better on European wheels?
European single-zero wheels have a lower house edge than American double-zero wheels, but Martingale still cannot invert the negative expectation.
