24+8 Roulette Strategy - Profitable or Not?

Last updated: 05.04.2024 by Andrew Shepard

If you are a roulette player, you will probably have heard at least one time about the 24+8 system. This roulette strategy took its name from the number of cells that a player covered in each round. Unfortunately, we didn’t manage to find a lot of things about the history of the 24+8 strategy, but we found a video from the CEG Dealer School on YouTube.

The reason that we mention this video review is that there are numerous people who debate in the comment section about if this system is profitable or not. This is also one of the reasons that lead us to test this strategy to figure out if it's good or not.

How you Can Run the 24+8 System

Like numerous other roulette strategies, the player that runs the 24+8 systems needs to place multiple simultaneous bets in each round. The first bet requires you to place £10 each on any two of the total three Dozens. Now, in the third Dozens that you leave without a bet, you have to place £1 on 10 of the total 12 numbers. This is it, the 24+8 system covers 34 out of 37 numbers in roulette and comes with a 91.89% chance of winning a round.

You may now wonder what will be your move if a spin lands on the losing 3 numbers. In this situation, we will follow the Martingale betting system that tells us to double the size of our bet until we hit a winning spin. Let’s see a visual roulette table that the 24+8 system is placed.

24+8 System

For the purposes of our tests, you can see that we have placed £10 on the first (1-12) and third (25-36) dozens. Next, we also bet £1 on numbers 24, 23, 22, 21, 20, 19, 17, 15, 14 and 13. This leaves us with three numbers uncovered, the zero, 18, and 16.

As we have bet a total £30, let’s see what are the three scenarios that we can expect from every round.

  • One of our two Dozens bet wins: This situation comes with a 64.86% odds to happen and will result in not losing or winning money.
  • A straight-up number wins: In this example, we will gain a £6 profit. A straight-up win in the 24+8 system has a 27.03% probability to occur.
  • One of the three numbers that we don’t bet wins: The outcome that we fear results in a £30 loss and has 8.11% odds to happen.

But what will happen if we take this system and test it in 5 fictitious spins? Let’s see together:

  • Spins 1

    One of our two Dozens wins the round, and the spin results in a push.

  • Spins 2

    The ball lands on number 24, and this means we won a straight-up bet. We now have a £6 profit.

  • Spins 3

    Another Dozens win, so we continue to have a £6 total profit.

  • Spins 4

    The ball stops on number 17, in which we have placed a straight-up bet. We now have a £12 total profit.

  • Spins 5

    Unfortunately, none of our bets wins in the spin 5. This means we face a £30 loss, and we are down £18. As we said above, after a loss in this system, you should double your bet until a winning spin occurs.

24+8 Strategy on Simulation Tests

Of course, this 5 spins simulation isn’t enough to conclude safe results. This is why we decided to test the 24+8 roulette system using a Google Sheets tool. To make the test even more precise, we managed to factored in the use of the Martingale system. This means that every time we lose a round, we will double our bet, every time one of our straight-up bets wins, we will return to the initial bet, and if a Dozen wins the spin, we will not change our bet.

To make a long story short: we decided to put five fictitious players in this test and give them a £1000 starting bankroll to see how they will go with a decent starting balance. We run the test through 500 consecutive rounds and these are the results of this experiment:

24+8 Strategy

There is no need to look at the graph for many minutes to understand how the 24+8 performs in the long run. The 24+8 roulette system sended every player in a nosedive path that none of them couldn’t recover. Our most successful player was the player number 3, who managed to reach his bankroll to £1.060 after 55 spins. However, he also couldn’t prevent the downhill and finished the 500 rounds with a total loss of £288.

Of course, we see that all players faced some sharp declines through this test, and you may wonder why this happened. Well, this is probably due to the Martingale system, which told the players to double their bet size amount every time they lose a round.

But as we know, you are now wondering what would happen if the Martingale system wasn’t in this test, we decided to run another 500-round test but without the double-up strategy. In this experiment, we will now use three players, and all will start with £1000 starting balance. Let’s see what happened:

Strategy 24+8

The results of this particular test show that our modification made a solid impact. Even though all players finished the test with losing some of their balance, the losses aren’t so big. In a few words, the Martingale system proves to be a disadvantage on this system on both long and short runs, and players may want to use the 24+8 system without it.

The Drawbacks of the 24+8 Roulette System

As you can see on our tests, the 24+8 roulette system didn’t have a successful outcome in the long run. Of course, if you take out the double-up system, you may manage to end up with some profit in the short term, but you will always finish with losses after numerous spins.

Another drawback of this system, regardless of the double-up strategy, is that the 30 units bet on each round can be difficult to handle by many players. If we also add to this the Martingale system, we can easily understand that this strategy can’t be supported by too many players.

Wrap Up

To sum up, we tested the 24+8 roulette strategy in two different configurations, and we ended up with pretty much the same results. If you use the Martingale system on the 24+8 strategy, you will probably run out of money after a decent number of spins.

On the contrary, if you exclude the double-up system, you will not face such big losses in a short time. However, even if you don’t implement the Martingale system on your 24+8 strategy game, you will end up losing money in the long run. Of course, both of the ways showed some small gains in some short periods, and this can be used by players. Summing up, if you decide to play the 24+8 system, we suggest you don't stick with this system for too many rounds.
