Grand Martingale System – Test & Analysis

Last updated: 05.04.2024 by Andrew Shepard

The Grand Martingale system is a popular variation of the classic. So, if you are not familiar with the Martingale system, you may do so by reading up on our dedicated guide for the system. If you already have a working knowledge of how the system works, it’s time to expand on it. You will be able to implement Grand Martingale betting system into your gambling easily owing to your previous experience with the original system and have a great time at it. Martingale is a non-progressive system that does invite a certain amount of risk, but it’s generally considered to be very easy to understand and follow through. Let’s take a look at how the system holds up, and more importantly – what is Grand Martingale system really?

How Does Grand Martingale Work

Right, so, just like the regular version of the strategy, you will be betting on Even Money bets, or Black/Red, High/Low or Odd/Even. You set a minimum wager of R1. If you lose, you double the bet, and add the base unit, or another R1. So, if you bet R1 and lose, you will then bet R2 + R1, for a total of R3.

Grand Martingale Strategy

Let’s quickly look at several rounds of Grand Martingale strategy in practice, making it much easier to follow.

  • Spin 1

    You bet R1 and lose.

  • Spin 2

    You now bet R2 + R1 for a total of R3. You lose.

  • Spin 3

    You bet R6 + R1 for a total of R7. You win.

  • Spin 4

    You bet R1 and play the next round based on this round’s outcome.

Taking Grand Martingale for a Test

To give you the best possible idea of what to expect when you use Grand Martingale during your own gaming sessions, we have tested the strategy with 3 players running a Google Sheets simulation. Each player has a bankroll of R1,000 and 1,000 rounds to try Grand martingale. Here is what the results suggest.

Right, as you can see, there were a few drops along the way. The yellow player certainly felt the pinch, almost breaking his bankroll very early into the game, and then recovering, but continuing to experience abrupt and deep losses. Regardless, his overall bankroll continued an upward trajectory, hitting almost R2,000, as have all others.

The red and blue player had much less scary outcomes, and they too continued to climb up and increase their bankrolls. The red player experienced a decline after 620 rounds to around R500 bankroll available, but recovered and continued their upward trajectory. For all intents and purposes, Grand Martingale could very well be one of the best strategies to try that any casino has to offer as of right now. But is this always the case? Let’s have a look at how Martingale compares against Grand Martingale.

Grand Martingale

Alright, what we see from the example below is that Grand Martingale once again produced a much steeper decline. But this steep decline is not necessarily all negative. For one, it picks the pace of the progression, which means that the winnings are also growing at a much steadier rate as well.

Grand Martingale accumulates 35% faster, which admittedly can go either way, but its also where the fun of the strategy lies. The good news is that no matter whether you stick to one or the other, once you lose 9 times, you usually don’t have the money to place a tenth bet – as indicated by our example here, although Martingale does provide you with one extra attempt. But what are the exact odds of hitting a wall in European Roulette? Our testing puts the number as follows.

Martingale:

P = (0.524)^10 = 0.1275%

Grand Martingale:

P = (0.524)^9 = 0.2433%

The Potential Dangers of Grand Martingale

Of course, just like any other strategy, Grand Martingale does court with disaster in a way. The system suggests that you need to be willing to take what can be huge risks on occasion. Yet, as our extensive testing showed, out of the four times we tested the system with R1,000 and over 1,000 rounds, we were able to reach 2,000 rounds.

Yet, just because our testing didn’t reveal a bankroll breaking occurring situation this doesn’t mean it won’t happen. It’s important to take it in stride and decide if you want to play up to 1,000 rounds, as this will take a while. Grand Martingale is a strategy that works best when you know when to stop the sequence, cash in, and withdraw from the table.

The other danger with a Grand Martingale system is that you need to bring enough money to the table to be able to absorb the shocks. What’s more, if you have more than R1,000, and come with a R2,000 budget as a safety net, you may be even safer. Remember, there is roulette table limits, but they are usually set at R2,000 and you can still find a good roulette table that starts at R1. Question is if you are \willing to bring that much money to a game of roulette.

Conclusion

Grand martingale is a strategy that has its applications. It seems to be a slightly better option than Martingale, because the added unit bet is not so detrimental to your progression per se, although it does make things move at a slightly quicker pace overall. The progression is quicker, yes, and this makes the strategy appealing to players who wish to be a little riskier with the way they play and bet. Grand Martingale does provide just the right amount of risk-reward that is within the comfort zone of many players out there, and this is precisely what makes it a great stratagem to explore yourself in the first place.
