As part of his projects, D’Alembert created a betting system that bears his name and is used by gamblers even today. Let’s check it out and see if it can help you win more at roulette.
The Concept & How It Works
Jean le Rond d’Alembert(1717 – 1783)The D’Alembert system is really simple, especially in contrast with strategies like Labouchere, for example. The core idea is pretty similar to the classic Martingale system, but with one important difference – the bet progression in the D’Alembert method is much flatter than the aggressive doubling down of Martingale. This results in one of the safest and easiest to execute roulette strategies.
The system is designed to work for bets that have a chance of winning close to 50% – the so-called ‘even’ bets. Those include Red/Black, Even/Odd, and 1-18/19-36. The logic is that those bets will eventually even out – a long streak of red will surely be followed by a long streak of black.
You need to determine a ‘unit’ that will be the backbone of your D’Alembert strategy. It can be a chip or a select amount of money – it’s up to you. It can be as small or as big as you wish, but keep in mind that you might end up wagering several of them at a time, so you must make sure that the unit value no more than 1% of your total funds. Experts claim that the safest amount is either 0.50% or 0.33%.
The strategy consists of you gradually increasing your bet when losing games and gradually decreasing it when winning. You start with one unit and add or remove a single unit when necessary. The table will show you how a typical game might go when you are using the D’Alembert system.
| Round | Bet | Outcome | Total Profit |
|---|---|---|---|
| Round 1 | 1 | Win | 1 |
| Round 2 | 1 | Win | 1 |
| Round 3 | 1 | Loss | -1 |
| Round 4 | 2 | Loss | -2 |
| Round 5 | 3 | Loss | -3 |
| Round 6 | 4 | Win | 4 |
| Round 7 | 3 | Loss | -3 |
| Round 8 | 4 | Loss | -4 |
| Round 9 | 5 | Win | 5 |
| Round 10 | 4 | Win | 4 |
| Total Profit | 2 | ||
As you can see, even when the number of wins and losses are identical, you still come out at a profit.
Pros of the D’Alembert System
As far as safe betting strategies go, the D’Alembert system definitely takes the cake. You can utilise it at whichever of the best online casino UK websites for real money with a relatively small bankroll, and the nature of the progression pretty much keeps you safe from hitting the dreaded table limits – which can be a common occurrence when using many other roulette strategies. Of course, a terrible losing run is never out of the question – but overall, it’s pretty hard to reach absurdly high stakes while using this system.
In addition, the system is really easy to learn and master. You don’t need to write anything down, just keep the size of the bet in your head and adjust it according to how well you are doing. You can always check the top-ranked roulette sites in the UK and test how this strategy works.
Cons of the Strategy
Since the D’Alembert system is low-risk, you cannot expect high gains from it. You bet small amounts, so you will win small amounts. But in case playing with smaller bets is what you want, then definitely explore the low roller roulette casinos in the UK. You will most likely aim to get an equal number of wins and losses, but this is unlikely to happen over the course of a longer game – after all, the house always ends up winning.
Also, if the odds are not in your favour and you hit that horrendous losing streak, you will probably have a hard time recovering from it. The only chance is an equally good winning streak, and those tend to be pretty rare.
Tinkering with the System
Since the D’Alembert method is pretty old, there are many variations and additions that have spawned over the years. The overall simplicity of the system makes it a very good foundation based on which you can devise your own betting strategy for roulette. Here are some ideas that we tinkered with while working on this article.
Bet Progression
Tinkering with the original bet progression can bring interesting results. For example, instead of removing only one unit from the bet upon winning, we tried resetting the bet to one. This will result in really, really low losses, which will be compensated in a way by the winnings. However, when you put the casino edge in the equation, you will eventually end up at a small loss.
Don’t let the casino advantage discourage you – those numbers add up in the long run. There is the possibility of you going on an awesome winning streak and cashing in your winnings afterwards.
Contre D’Alambert
Like most other betting systems, the D’Alambert strategy too has its ‘Reverse’ version. It works exactly like the original, only the other way around. You increase your bet after a win and decrease it after a loss. Let’s compare this method to the regular D’Alambert using the same example from before.
| Round | Bet | Outcome | Total Profit |
|---|---|---|---|
| Round 1 | 1 | Win | 1 |
| Round 2 | 2 | Win | 2 |
| Round 3 | 3 | Loss | -3 |
| Round 4 | 2 | Loss | -2 |
| Round 5 | 1 | Loss | -1 |
| Round 6 | 1 | Win | 1 |
| Round 7 | 2 | Loss | -2 |
| Round 8 | 1 | Loss | -1 |
| Round 9 | 1 | Win | 1 |
| Round 10 | 2 | Win | 2 |
| Total Profit | -2 | ||
As you can see, the results are not as positive as with the regular system. However, the Contre D’Alembert requires an even smaller bankroll, and if you are on a huge losing streak, you don’t need to wager a lot of chips at once to recover from it.
The D’Alembert System Is Fun and Easy to Use
The D’Alembert system is one of the easiest and worry-free ways of playing roulette that we know of. The strategy is plain and simple, and works like a charm – but don’t expect to become a millionaire while using it. The winnings will be small, and you will inevitably be at a loss in the long term. Thank the casino advantage for that.
Still, we highly recommend trying the system out. It’s a good way to get started with roulette strategies before you feel confident enough to take on riskier systems that have the potential to bring you a lot of money.
