How to Use the Martingale Playing Roulette

The Martingale betting system requires that you double your bet after each losing spin until you win.

The goal is to win back the money you’ve lost on your previous spins. As a side note and it’s important, test the strategy by playing roulette for free before you play for real.

After a win, you’ll revert to your original bet. The premise of the Martingale is simple and easy to use.

Depending on the online roulette version you can use the Martingale for as little as £0.10 to £100.

However, the Martingale works best on even money bets. In other words, use it to bet on Red/Black, High/Low Bets, or Even/Odd.

Round Bet Amount Outcome (Win/Loss) Total Profit/Loss
1. £1 Loss -£1
2. £2 Loss -£3
3. £4 Win +£1

In this example, after two consecutive losses, the third bet of £4 results in a win.

Despite losing £3 initially, the £4 win returns the total profit to £1. Note that it’s the original base unit.

While the Martingale strategy can be effective theoretically, it requires a large bankroll to withstand consecutive losses.

That also depends on the limits of table stakes in casinos.

Real-Life Example Martingale Betting Strategy

Do we know of a famous person who used the Martingale betting system to play roulette to win money?

Yes, Charles Wells a British engineer bankrupted himself in 1891 at Monte Carlo. He used a variant of the Martingale strategy.

Initially winning millions by doubling his bets after losses at roulette, his luck abruptly turned. Sadly he lost everything to the casino within days.

Despite his early success, the strategy’s inherent risk and the casino’s statistical edge ultimately led to his financial ruin.

Using the Martingale System European Roulette

We tested the Martingale betting strategy playing European roulette for free over 100 spins. The roulette wheel has a single zero (o).

The odds calculation differs from the American roulette version with the double zero (00).

At an average stake or base betting unit of £0.10, our starting bankroll was $100.

The system worked quite well but we did experience a few glitches. After the conclusion of 100 spins, we made a profit of £5.

At one stage during the testing, we experienced 10 consecutive losing spins. The odds of that occurring in European roulette is 0.1275% and for American roulette, it’s 0.1631%.

Mathematical Probability of Using the Martingale

Here’s a breakdown of the mathematical aspects and the probability of the Martingale strategy winning in roulette:

Single Zero (European) Roulette

The probability of winning a bet on red or black playing European roulette is around 18/37 ≈ 0.4865.
Due to 18 red pockets, 18 black pockets, and 1 green pocket (zero).

Cons of Using the Martingale Betting Strategy

The Martingale betting system, while seemingly straightforward and potentially profitable, comes with a few pitfalls:

Risk of Quick Losses

The strategy hinges on doubling your bet after each loss to recover previous losses to earn profit.

However, a streak of losses quickly increases the size of your bets. If you start with $1 and hit 5 consecutive losses you’ll wager $32.

If you lose again, the next bet would be $64, and so on. As you can say, it can drain your bankroll fast if you use it recklessly.

Table Limits

Online casinos with UK licenses impose table limits. That prevents players from unlimited doubling strategies like the Martingale.

Even with a large bankroll, you can reach the table limit before recouping your losses.

This effectively ends the strategy’s effectiveness in recovering losses.

Bankroll Requirements

To use the Martingale betting system effectively requires a substantial bankroll.

High-stakes roulette players can therefore weather potential losing streaks.

You can recover from smaller losses after a few wins. But, a prolonged losing streak will deplete even a sizable bankroll.

Probability and Gambler’s Fallacy

Each spin or round in roulette is independent from the previous one. The belief that a win is “due” after a series of losses is the gambler’s fallacy.

That usually leads to poor decision-making under the Martingale strategy.

Psychological Impact

You can exacerbate your losses if you’re an emotional player. Set yourself a clear goal, and if you’ve won money, withdraw your winnings via PayPal.

Not Suitable for Long-term Profit

While the Martingale can show short-term gains it’s not a sustainable long-term strategy.

We pointed that out during the testing phase since the risk increased the longer we played.

Besides, the house edge in casino games like roulette guarantees the casino a profit over the long run.


If you search for a real money betting system to play roulette online you’ll probably encounter the Martingale.

We’re the first to agree that it offers huge winning potential. Yet, it’s not a feasible strategy to use for prolonged play.

Inherently it’s flawed since the strategy claims you will win eventually.

Moreover, many so-called “reputable” authors swear by the Martingale. They’ll advertise their winning stratagems for a fee that guarantees you to win money.

There’s no such thing since roulette is a game of chance. Since the Martingale system favours even money bets, the progression moves slowly.

Finally, the Martingale betting strategy is not a “scam’. It can work, but you must know when to stop using it.
