A Complete Guide to the Martingale System for 2025
The Martingale system remains the most popular betting strategy in casinos thanks to its simplicity and alluring potential. It gives players the chance to generate profit whilst following a mathematically-driven technique.
Discover how to use this strategy, its benefits, and how to apply it in casino games like roulette, blackjack, and baccarat. Whether you’re a seasoned player or just want to learn more about the Martingale system, we’ll help you understand it and determine if it’s the best strategy for you.
The Martingale System – What Is It?
Created back in the 18th Century, the idea behind the Martingale betting system is to double your wager following a loss. The key concept is that, theoretically, you cannot lose each time and will eventually win.
Therefore, you should keep on betting to ultimately recuperate any previous losses and make a small profit. It’s primarily used in casino games that use even-money wagers, including roulette, baccarat, and blackjack.
How Does the Martingale System Work?
The Martingale betting system is easy to grasp, there are no complex procedures, hands, or charts to remember. You start by betting on an even-money bet, where the odds of winning are 50/50. A perfect example would be a coin flip, where the results can be either heads or tails. If you lose, you simply double your last bet amount until you secure a win.
Here’s a simple example to help you understand how the Martingale system works.
- You place your first bet, say £1.
- If you lose, you double your bet to £2.
- If you lose again, you double once more to £4.
- This is repeated until you win.
- Once you win, your profit will be equivalent to your initial bet. If you’d like to start again, you begin with the initial £1 wager.
A Simple Illustration of the Martingale System
In the table below, we’ve demonstrated how the Martingale system works to help you understand it.
| Round | Bet Size | Win/Loss | Bankroll Balance |
| 1 | £2 | Loss | -£2 |
| 2 | £4 | Loss | -£6 |
| 3 | £8 | Win | +£2 |
| 4 | £2 | Loss | £0 |
| 5 | £4 | Loss | -£4 |
| 6 | £8 | Loss | -£12 |
| 7 | £16 | Loss | -£28 |
| 8 | £32 | Loss | -£60 |
| 9 | £64 | Win | +£4 |
This table shows that with the first win, the player recovers all previous losses and nets a £2 profit, which is the initial wager. The player starts again with the original bet, experiences five losses, and is then successful. At this point, the player decides to stop as losses are recovered and profits are doubled to £4.
Although it ultimately results in a profit and the initial bet was small, you can see how quickly the stakes increase from the examples above. Therefore, an extended losing streak can easily lead to significant losses and drain your bankroll.
The Martingale Betting System in Roulette
Roulette is one of the most popular games for the Martingale system. This is because this system is ideally used on even-money bets that stand a 50/50 chance of winning. These can be black or red, high or low, and odd or even. This system is one of the higher-risk roulette strategies as bets double each time on a losing streak and can significantly impact your bankroll.
Helpful Tip: With a house edge of 1.35%, French Roulette with La Partage rules offers the most favourable roulette odds. Meanwhile, European Roulette has a house edge of 2.70%. Therefore, these two roulette variants are the best options to increase your odds of winning when using the Martingale system.
The Martingale Betting System in Blackjack
The Martingale system in blackjack can be a bit more tricky to apply. It doesn’t factor in changes in your hand or your betting options, including doubling down or splitting. Therefore, an alternative blackjack strategy, including a basic strategy chart or count counting can yield better results.
Helpful Tip: If you’re learning how to play blackjack, it’s better to use a strategy chart as the Martingale system can be risky. The Martingale system is better suited for high rollers as long losing streaks is not unusual in blackjack. Without a substantial bankroll, doubling your bet time and time again after a loss could result in a depleted backroll.
The Martingale Betting System in Baccarat
With a house edge of 1.06% for the Banker’s hand, the Martingale system is another popular baccarat strategy. As the odds are almost 50/50, the Martingale system can be a useful tactic to make a profit. You simply need to double your bet until it results in a winning bet, however, this approach is risky so setting a budget is important. Ensure that you can afford your staking plans.
Helpful Tip: Make the most of the free game selection offered by the best UK casino sites. Try the game in demo mode to try out the Martingale system and get a feel for how it works without risking any real money.
Pros & Cons of the Martingale Betting System
The Martingale system is a well-known betting strategy, often used in casino games like roulette and baccarat. While the approach is enticing due to its simplicity and the chances of long-term success, it has both its strengths and weaknesses.
Pros:
- Straightforward and easy to use
- No experience is needed to apply
- It can work in the short term as a way to recuperate your losses and gain a small amount of profit
Cons:
- High risk of significant losses
- May need a large amount of funds to work effectively
- Many casinos have a table betting limit, which you can quickly reach during a long losing streak
- The casino maintains its house edge
The Grand Martingale System
The Grant Martingale system is a more intense version of the classic Martingale approach. While you simply double your bet after a loss in the latter, the Grand Martingale adds an additional and fixed amount to each wager. This is generally the original betting unit. Although it can help you regain losses faster and make a better profit, the risk is higher as the house edge doesn’t change.
How the Grand Martingale System Works
The Grand Martingale system is a betting system based on the classic Martingale system. However, instead of just doubling your wager, you include a secondary bet too. Below, we’ve provided an example and included a step-by-step guide.
- Place your first bet, say £1.
- If you lose, double your bet plus an extra single bet. In this case, you would bet £3 (double £1 + £1).
- If you lose again, bet £7 (double £3 + £1).
- If it’s another loss, bet £15 (double £7 + £1).
- Keep going until you win. By then, you would have recovered your losses and made a profit.
Other Betting Strategies
Although the Martingale system is a straightforward betting approach, there are several other strategies that you can use. These include:
- Fibonacci – A progressive betting system where you raise your stake according to the numbers in the Fibonacci sequence following a loss. Meanwhile, you go backwards two numbers if you win.
- D’Alembert – In this betting strategy, you raise your stake by one unit following a loss and lower it by a unit following a win. In contrast to the Martingale, this offers a more cautious and less risky strategy.
- The Kelly Criterion – Using a formula, you determine your bet size based on the probability of winning and how much you can potentially win. Unlike the Martingale betting strategy, it works better in the long run. However, it is harder to implement when the chances of losing and winning are almost equal.
- Reverse Martingale/Paroli – Another positive progression system that is designed to take advantage of wins. In this system, you double your bet after a win and revert to the initial bet following a loss. As the name implies, it works as the inverse of the classical Martingale system and focuses on making the most of successful bets, rather than recouping losses.
A Comparison of Common Betting Strategies
Finding a strategy that works for you depends on several factors, including your risk tolerance, experience, and bankroll. Below, we’ve summarised the key elements of the most popular betting strategies to help you determine which technique meets your needs.

Top 5 Tips When Using The Martingale System
The Martingale system is an alluring and popular strategy thanks to its simplicity and the potential to recover all losses after a win. However, it can be risky. Therefore, we’ve listed the top five tips to keep in mind when using this approach.
- Begin with small wagers – Lower-value wagers can reduce the risk of depleting your funds quickly and give you more time to recover losses.
- Set a budget – The baccarat, blackjack, and roulette Martingale system can result in significant losses so responsible gambling is essential. Before playing, set a limit you are comfortable with and once you reach it, it’s best to walk away. Alternatively, you can set a cap on how many times you double your bet after losing, known as the Mini Martingale system.
- Pick games with equal odds and high RTPs – While the Martingale system does not alter the house edge, go for games that offer odds as close to 50/50 as possible. These include European and French Roulette with La Partage rules, baccarat, as well as even-odds sports betting. Besides featuring almost 50/50 odds, these games offer high RTP percentages, which boost your chances of winning in the long run.
- Pay attention to table caps – Many platforms, especially live dealer casinos, set minimum and maximum limits on bets. This can impact how much you’re allowed to bet when you’re experiencing a losing streak as you won’t be able to keep on increasing your bet.
- Play in demo mode – Before betting for real money, take advantage of free versions of the game you’d like to play. The best blackjack and roulette casinos allow players to play their virtual selection in free mode. This gives you a chance to practise the Martingale system without risking any real money.
The Martingale System – Final Thoughts
The Martingale system can be a straightforward way to regain any losses and make a small profit. However, it is a high-risk strategy that can lead to significant losses during long losing streaks. This makes it crucial to set a budget and stick to it. Just like with any type of gaming, playing safely and being aware of your spending limit is essential.
