The Martingale system is a betting strategy based on changing your stake after a loss rather than changing the selection you are betting on. Below, NetBet Casino delves deeper into the details of this system, which is mostly associated with table games.
It is important to remember that the traditional version is simple:
- Start with a predetermined stake.
- If the bet wins, return to your original stake.
- If the bet loses, double your next stake.
- Continue doubling after each consecutive loss.
- Once a bet wins, return to the original stake.
The theory behind the system is that one eventual winning bet can recover the previous losses and produce a profit equal to the original stake.
For example, someone starting with a €5 stake might bet:
| Result | Stake | Cumulative position |
|---|---|---|
| Loss | €5 | -€5 |
| Loss | €10 | -€15 |
| Loss | €20 | -€35 |
| Loss | €40 | -€75 |
| Win | €80 | +€5 |
The important point is that the system does not change the probability of the underlying game. It simply changes how much money is being risked from one bet to the next.
How Does the Martingale Strategy Work?
The Martingale system is normally associated with even-money bets.
In roulette, for example, these can include bets such as:
- Red or black
- Odd or even
- 1–18 or 19–36
These bets may look close to 50/50, but roulette contains the green zero and, on some wheels, 00. This gives the casino an advantage.
The Martingale system assumes that a win eventually arrives before the player runs out of money or reaches a betting limit.
That is where the main problem lies.
After every loss, the required stake increases exponentially.
Starting with €5:
- 1 loss = €5
- 2 losses = €10
- 3 losses = €20
- 4 losses = €40
- 5 losses = €80
- 6 losses = €160
- 7 losses = €320
- 8 losses = €640
- 9 losses = €1,280
- 10 losses = €2,560
After ten consecutive losses, the next stake would need to be €5,120.
The total amount already wagered would be €5,115.
This illustrates why the Martingale system can appear successful for a while but become extremely risky during a losing streak.
Does the Martingale System Actually Work?
Not as a way of overcoming the house edge.
The Martingale system can produce frequent small winning sessions because a single win can recover previous losses. However, those relatively frequent wins come with the possibility of a much larger loss when a sufficiently long losing sequence occurs.
The strategy does not alter the underlying mathematics of the game.
If a roulette bet has a house edge, doubling your stake after losing does not remove that house edge. Over a sufficiently long period, the expected relationship between money wagered and losses remains determined by the game’s mathematical advantage.
In other words, Martingale changes your betting pattern, not your odds.
This is one of the fundamental problems with betting systems generally: a staking strategy cannot turn a negative-expectation game into a positive-expectation game.
Why Does Martingale Sometimes Look Like It Works?
The psychology of the Martingale system is one reason it remains popular.
Most individual losing sequences are relatively short. A player might experience:
Loss → Loss → Win
and finish the sequence with a small profit.
Repeating this can create the impression that the strategy is working.
The problem is that the occasional long losing streak can be disproportionately expensive.
The system effectively trades many relatively small wins for the risk of a potentially very large loss.
This is sometimes described as picking up small gains while accepting a much larger downside when the progression eventually fails.
Which Games Can You Use the Martingale System On?
The classic Martingale system is most naturally associated with games offering approximately even-money outcomes.
Martingale on Roulette
Roulette is probably the game most commonly associated with the strategy.
A player might select red or black and begin with a €5 stake. After a loss, the stake becomes €10; after another loss, €20, and so on.
However, the presence of the zero means red and black are not truly 50/50 propositions on a standard European roulette wheel.
The roulette ball also has no memory. If black has appeared several times consecutively, that does not make red “due”.

Martingale on Blackjack
Blackjack presents a complication because it is not simply an even-money win/loss game.
Hands can result in wins, losses, pushes and blackjack payouts, while the player’s decisions also affect the outcome.
A Martingale progression therefore does not translate as cleanly to blackjack as it does to a simple even-money roulette wager.
If you want to understand the underlying game rather than simply change your stake after losses, learning basic blackjack strategy is a more meaningful approach.

Martingale on Other Games
The principle can technically be adapted to other betting situations where a player can identify a binary or approximately even-money outcome.
However, that does not mean it becomes mathematically effective.
The more complicated the game’s rules and payout structure, the less naturally the traditional Martingale progression fits.
What Are the Pros of the Martingale System?
Although Martingale does not eliminate the house edge, there are reasons it remains attractive to some players.
Simple to Understand
The basic rule is easy:
Win → reset. Lose → double.
It does not require complex calculations or specialist knowledge.
Frequent Small Winning Sessions
Provided a player has enough bankroll and does not encounter a long losing streak, the system can result in a series of small session wins.
Easy to Apply to Certain Bets
The strategy is particularly straightforward when applied to even-money-style roulette bets.
No Need to Predict a “Winning” Number
Unlike some approaches to roulette, Martingale does not require players to predict individual numbers. The player simply selects one side of an even-money market.
What Are the Cons of the Martingale System?
The disadvantages are considerably more important.
Stakes Increase Very Quickly
The defining problem is exponential stake growth.
A sequence of losses can turn a small starting bet into a very large required wager surprisingly quickly.
Bankroll Limits
Every player has a finite bankroll.
A player may theoretically be able to recover from several losses if they have sufficient funds, but there is no unlimited bankroll.
Table Limits
Casino games also have maximum bet limits.
Even if you have enough money to continue doubling, the table may prevent you from placing the next required wager.
It Does Not Change the House Edge
The most important disadvantage is mathematical.
Martingale does not make an unfavourable game favourable.
Losing Streaks Happen
A previous sequence of results does not make a particular outcome “due”.
If red has appeared ten times, black is not guaranteed to appear next.
Martingale vs Card Counting
Martingale is sometimes discussed alongside card counting, but the two concepts are fundamentally different.
Martingale is a staking system. Card counting is an information-based blackjack strategy.
Martingale changes the size of your bets according to previous wins and losses.
Card counting attempts to estimate how the remaining composition of a blackjack shoe may differ from the starting composition. Systems such as Hi-Lo assign positive, negative or neutral values to cards and maintain a running count.
Card counting is therefore based on information about cards that have already been dealt, whereas Martingale simply reacts to the outcome of previous bets.
Is the Martingale System Viable?
The Martingale system can be used as a staking approach on suitable games, but that does not make it a reliable way to make money.
Its biggest weakness is the relationship between small potential gains and rapidly increasing exposure.
Someone using the system might have many successful sequences before encountering a losing run that wipes out a substantial amount of previous progress.
For anyone considering a betting system, it is therefore important to understand that a staking system cannot guarantee profits.
Martingale System FAQs
What is the Martingale system?
The Martingale system is a betting progression where a player typically doubles their stake after a loss and returns to their original stake after a win.
Does the Martingale system work?
It can produce winning sequences, but it does not overcome the mathematical house edge. A long losing streak can create substantial losses.
Is Martingale good for roulette?
Martingale is most commonly associated with even-money roulette bets such as red/black. However, the strategy does not remove the roulette house edge and can expose players to rapidly increasing stakes.
Can you use Martingale on blackjack?
A betting progression can technically be applied to blackjack, but blackjack has more complex outcomes than a simple even-money bet. Basic blackjack strategy is a more meaningful way to approach decisions than simply increasing stakes after losses.
Is Martingale a guaranteed strategy?
No. There is no guarantee that a win will occur before a bankroll or table limit prevents the next required bet.
