Showing you players again in the same setup without limits, we get the following chart:. Not too much, actually, except that there are a number of trajectories curves that are in the region between the bunch at the top and the flat bottom line of total loss.
We can see that those come at any various heights. This is a result of the following effect: if a player loses several times in a row after a while of winning, it happens that the amount left to bet is lower than the player would need to double up for the subsequent bet. If they lose, they land at zero anyway.
But if they win, they cannot fully recover to where they were at, before the losing streak had begun. They just recover to the amount that was left to bet, which is somewhat lower than the bulk of recovering curves at the top of the chart. But does that behavior simply continue? How far can the top bunch keep winning and increasing their money in hand? Here we notice the bulk at the top getting thinner towards the right of the chart. More and more players are dropping from the top.
One can see this best by observing all the curves that dive to zero over time. The only reason this looks like a single line is, that they lie on top of each other exactly , unlike the ones at the top of the figure. But let us not stop there. Scaling up by a factor of 10, we arrive at rounds, i. This sounds like a lot, but can certainly be done in successive sessions. Alright, players playing for rounds:. Finally, we see some clear development: Almost all of the players drop to zero over the course of rounds!
In this particular example, two of them are still alive and playing, and with substantial amounts of cash in their hands. All others keep in mind, 98 percent in our example have lost all their money! The result: total elimination:. In this particular example, all players are out of money before they reach rounds. Granted — that corresponds to a long time playing, like hours or 26 days non-stop, without ever sleeping or doing anything else. But hey, over time, you can certainly accumulate that sort of amount of playing rounds.
You know what? What can we expect from this? More densely populated areas on the graph and more extreme outliers. Alright, here we go — 10 players for 60 rounds:. Remember that I showed you these graphs in order to get a feel for what is happening in the simulation. However, graphs like these are not ideally suited to start interpreting what is going on. For that purpose, we need something else.
What does that mean? Plus, you cannot go beyond this. But is it really that bad? Here they are:. Ok, now that looks less stellar than just a moment ago in the unlimited fantasy world, right? But we still need to get to some actual numbers for probabilities that we can use, so here we go. Another way of asking this question would be this: how high is the probability of losing everything at Roulette with the Martingale system as after a given number of rounds?
In order to answer that question, I looked at the numbers for cash in hand at each round of the runs and prepared the appropriate means from the samples. Here is the result for the three main probabilities for a 7 step progression in the Martingale system with no table limits. We look at rounds of playing, and the result is based on runs:. Now, does that actually look any different? We have seen that, in the beginning of the game, a table maximum that matches your size of initial cash does not make a big difference.
Then we get restricted to 4 steps in the progression. Can we spot a difference there? Yes, that looks different, indeed. Probabilities for winning get lower, probabilities for losing go up, while the probabilities for a total loss go down. Probabilities for winning and losing cross much earlier. Can we extract any reasonable statements from these three charts? In principle, you can win half your starting bet per round on average with the Martingale System for Roulette.
This only holds true, however, if you avoid a total loss. This question should be approached with caution and a lot of sense for subtleties. In the simulation graphs above we have seen the individual amounts of cash rise and fall for all the simulated players. While most of them were falling, some of them the luckier ones went up to several thousands of dollars from a starting amount of roughly one thousand dollars before they eventually fell to zero, too.
However, when we considered table limits, the behavior of the curves changed dramatically, in particular in the long run. To make things a bit more clear, let us get back to those charts once more. The reason is that we have just learned that a lower table maximum reduces both the odds of winning overall and of a total loss. Furthermore, the curves do not go nearly as high as with the higher maximum.
Note that the scale on the horizontal axes is the same, but on the vertical axes is quite different:. Speaking of the average guy: the average amount of cash that a player has in hand goes down after each round. On average, the players lose, because the probability favors the casino. This is well known, but worth mentioning every now and then. The casino wins, now matter how the players play, due to the so-called house edge.
Speaking of which:. The short answer is: not really. But why not? The important circumstance is this that the Martingale strategy is a very particular system which capitalizes on doubling up and has its strength in the short term. The house edge works in the long term, however and affects the short term only a little. How exactly do we have to set up an experiment like this? The only difference in the simulation concerns the probability of winning a single round. The other parameters can be varied as we just did in order to study various effects of this and that.
This also corresponds to flipping a coin or a similar event of chance with fair odds. Ok, what are the results? We are looking at the same probabilities as above, now plotted out to rounds of playing, without a house edge:. I think this brings us to a point where we can begin to summarize the results of this in-depth analysis of the Martingale strategy for Roulette. The odds for the Martingale strategy in Roulette depend on a number of parameters.
It is straightforward to provide odds, e. The simple odds for a total loss during a single Martingale progression are given in the table above towards the beginning of this article. They are constructed via multiplying the number for the losing odds with itself as many times as there are steps in the progression. This means that in Roulette, we get for the European variant for the probability of a total loss as a function of the number of steps n. While this serves as a nice word of warning, it is not all we can do.
In the following table, I provide you with the average probabilities for a win any amount , a loss any amount , a total loss, as well as the average cash in hand after a variety of numbers of rounds and for different setups, e. All numbers are in percent. After our in-depth analysis of the Martingale strategy for Roulette, we have seen and can summarize the strengths and weaknesses of this system.
Honestly speaking, for some players, the system is profitable in the short term. All players lose everything in the very long term. And until that happens, the average cash in hand averaged over a large number of players decreases with every round. In more Details, we can find the following points regarding the profit made with the Martingale strategy for Roulette:. The most important thing to understand for me personally was the significant bump in winning probability for the average player during the first rounds of the game.
So I investigated this further and did a calculation and investigation of the first few rounds by hand, in a simple spreadsheet. And there I saw everything very clearly: why the probabilities for winning are so high in the beginning, and how the balance of wins and losses works. Do with this information here what you will, but I consider this article and analysis a strong warning against playing games of chance for money. If you found this analysis interesting and are also interested in various betting systems, I have another analysis for you.
It concerns the so-called Reverse Martingale strategy, which has some important differences. Is that any good? I am a nerd and trained in theoretical physics with a PhD and everything My interests are life as a human being and how computing can teach us valuable things about that as well as about nature in general.
Read more about me. In our family, we love to play board games with our kids. Mostly it is about a simple casino game such as roulette and a martingale betting system. The martingale system is as follows:. If you win, then you will recover the money you lost on the previous round and win a little extra.
There may be two different, yet popular opinions on this:. You can never lose all your money, as long as you have infinite amount of money. It is impossible in roulette to lose 10 times straight when placing the same bet. To prove that, I have made some simulations using Python and here are the results. I swear by the name of Science that the evidence I shall give shall be the truth, the whole truth, and nothing but the truth.
The script simulates roulette outcomes within a second. At each simulation, a random whole number between 1 and 36 is picked. I have intentionally dropped 0 to lose the house edge. Cool, right? This function iterates over the list containing odds and evens and counts the consecutive results.
In this way, a list of:. This creates a dictionary and counts the amount of odd- or even-streaks that occurred during 1,, simulations. The results are fascinating:. When playing roulette 1,, times in a row, it is possible to have 19 outcomes in a row that are the same.
Imagine using the martingale system described above and losing 19 times in a row. Your 20th bet would have to be , times larger than your smallest bet. Can you afford that? Note: In such extreme cases, table limits stop players from making bets that are astronomically high and hence the martingale strategy fails after a certain number of consecutive losses.
In python, we should add a few global variables and redefine our oddeven function. In an ideal world, you would never expect your money to get below 0. Oh no! There seem to be three extreme spikes indicating that our money went below zero. It was mentioned before that the martingale system works perfectly if you have tons of money or an infinite amount of money.
It is true if one can define such an amount. Before writing this article, one of my simulations showed a losing streak of 25 — you would need 33,5 million to recover from that on your 26th bet. I tried to get the best figure I could get in a few tries, but I can guarantee you that every time the script was executed, the average Joe went bankrupt.
To run this script multiple times in this case times , a batch file was created:. Out of these , none were successful. What if we modify those parameters a bit? Using a martingale betting system in roulette can destroy your wallet and therefore it would be wise to avoid it in the first place.
Nevertheless, if something has a chance of occurring, it can happen on 1st, th, th try. Keep in mind that the house edge was intentionally ignored. Hands-on real-world examples, research, tutorials, and cutting-edge techniques delivered Monday to Thursday.
