# Martingale betting system maths

The premise behind it? With the Martingale system, you can easily beat the house and walk away with a fortune in your pocket. But is this the reality? Top Tip! What it can do is help improve your chances. What is the Martingale Strategy? In a nutshell, the Martingale strategy instructs you to double your bet every time you lose.

The theory is that will help you regain your losses in subsequent rounds. This method dates back to the 18th century. That is the result of the fact that for 11 out of the 16 possible outcomes, the player wins, for 4 outcomes the player loses, and for 1 outcome the change in cash is zero. The overview graph and table for four rounds in the Martingale system ist the following: This table gets rather high rather quickly, in fact, exponentially with more rounds.

After four rounds, there are 16 possible outcomes. The consecutive losses, on the other hand, add up much more quickly. In the previous section we saw that after three consecutive losses, we arrive at a profit of Here is the situation for four consecutive losses: Doubling the bet after each loss, the bets are 1, 2, 4, and 8.

Losing all four rounds totals up to a profit of This is the result of the fact that not only the number of possible outcomes grows exponentially with the number of steps in the progression, but also the maximum bet after the same number of consecutive losses.

Some more moderate outcomes remind us of the general principles in the Martingale system. I prepared two further plots for you in this section. Both times the player wins two rounds and loses two rounds, just the order is a little different, and makes a noticeable difference as well. Here is the first variant with the sequence win — loss — loss — win: What happened here? The player wins the fist round, arrives at profit 1. Then the player bets the base amount again, loses one round, goes back to profit 0 and doubles the bet.

In round three, the player bets 2, loses, goes to profit -2, and has to double the bet one more time. This reiterates a pattern that we have seen before: the first win after a sequence of consecutive losses restores the profit before that sequence, plus 1. The sequence in this case is: win — win — loss — loss: Here the player wins twice in a row, betting the base amount for the first three rounds as a result, and arriving at a profit of 2 after two rounds.

Then, the player loses round three, going down to a profit of 1, and has to double the bet to 2 for round four. He loses one more time, thus arriving at a profit of So, in effect, there is a difference of 3 units of the base bet, just because the order of two wins and two losses in the four-step Martingale system was altered.

This kind of variety is very powerful and creates an interesting pattern that you can follow through the system by looking at the figures in this section and the next two. That is the result of the fact that for 23 out of the 32 possible outcomes, the player wins, for 7 outcomes the player loses, and for 2 outcomes the change in cash is zero.

To make this even more clear, we start the analysis of a couple of paths with 5 steps with the extremes again. Five consecutive wins go first: The important thing to note here is that the profit after five consecutive wins is 5 units of the base bet.

On the other hand, for five consecutive losses, we have the following picture: As we can read off the last line of the table, the profit after five consecutive losses is This is a drastic result of the exponential growth of the bet size after consecutive losses. At this point, however, it is interesting to point out the strength of the Martingale system as well. For almost the same outcome as the five losses in a row, the profit is positive, namely for four consecutive losses, followed by a win in the fifth round.

Take a look: While the win is not large, it is a net win nonetheless. The first is an alternating pattern of loss — win — loss — win — loss, which looks like this: This is intriguing: two wins make up for three losses, one of which happens in the last round.

The step-by-step walkthrough is as follows: the player loses in round one and goes to a profit of Then, betting the base amount, the player loses round three, which results in a profit of 0. Winning round four with a doubled bet of 2 gets the player to a profit of 2.

Now we can move on to six rounds and then summarize the observations and various statistics. That is the result of the fact that for 48 out of the 64 possible outcomes, the player wins, for 12 outcomes the player loses, and for 4 outcomes the change in cash is zero. The overview graph and table for six rounds in the Martingale system ist the following: There are 64 possible outcomes after six rounds, and the Martingale system distributes the corresponding profits rather interestingly. But first things first: The ultimate disaster after six rounds is a total loss of units of the base bet.

The bets just keep doubling and the player just keeps losing, every single time. Check it out. In general, a win in the last round gets the player back to a positive profit, in particular of one base unit higher than after the last win before that. Check that out, too, it is a pretty useful pattern to navigate the tables. Now, how about three more intermediate cases? Here we go. Once again, one of the keys to this success is that the last round is a win.

Then, on the other hand, it could have been much worse, right? Ok, on to the summary: Odds in the Martingale System For a 6 Step Progression: Overview and Summary The previous sections were important to understand how the Martingale system works in detail. Some of the counts of outcomes and probabilities that result from those are quite counterintuitive at first sight, but now you know, where they come from.

In terms of a summary, there are a couple of important takeaways: The Martingale system actually provides odds that are rather substantially in favor of the player, at least during the first couple of rounds. The large odds in favor of the player are balanced by the disproportionately large size of the losses for the few disfavorable outcomes. The total profit after a sequence of consecutive wins grows linearly with the number of rounds. The total profit after a sequence of consecutive losses grows exponentially with the number of rounds, and is negative.

As a result of the previous point, half of all possible outcomes at each step during a progression in the Martingale system must automatically be net wins. Each win after a sequence of consecutive losses restores the profit before that sequence of losses, plus one amount of the base bet.

The order, in which wins and losses occur in any given path through the Martingale system, is much more important than how many wins versus how many losses the path contains. Rearranging the order of wins and losses in any given playing sequence can drastically alter the resulting final profit. Alright, these are certainly handy things to know, and they give us pleasure to understand, right?

In the following table, I have collected the following statistics for each round from one to six: The sum of the profits of all outcomes. The maximum profit among all the possible outcomes. We expect this to be a positive number, albeit not smashingly large. The minimum profit among all the possible outcomes. We expect this to be an exponentially rising negative number. The count of positive outcomes, i.

The count of neutral outcomes, i. The count of negative outcomes, i. The probability of a net win. The number of positive outcomes, divided by the total number of possible outcomes.
