D’Alembert System – How the D’Alembert Betting System Works

The D’alembert system is also popular among blackjack players. This is because some iterations of blackjack boast a return-to-player (RTP) rate that’s in excess of 99%. In fact, the theoretical RTP rate for classic blackjack is 99.41%, equating to a $99.41 return for every $100 wagered.

In blackjack, all winning bets are also even money and paid at 1/1. The blackjack payout is marginally higher at 3/2, but generally speaking, you’ll either lose or double your money with each wager. This simplistic payout structure suits the D’alembert system, as does the implied probability of winning each hand.

However, there are rules in blackjack that may introduce complications. For example, when you double down or split cards, you are required to double your stake in the hand. You could simply avoid these options when employing D’alembert’s formula, but if you are following blackjack basic strategy, you don’t want to do that as this increases the house edge.

Instead, what you should do is increase your bet by two units if you double down and lose and decrease the unit by two if you win. If you split and lose both hands, increase the unit by two, if you win both, decrease by two; and if you win one and lose one, treat it as a push and keep the same bet. Here’s an example:

As we’ve already discussed, the D’alembert system is ideally suited to even money bets. This is why it’s synonymous with roulette, which features a number of so-called “outside bets” that pay at 1:1. These include Red/Black, Odd/Even, and High (19-36) / Low (1-18), which essentially afford you a 50% chance of winning.

While there are ample bet choices when wagering on roulette and deploying the D’alembert system, this is an incredibly fast-paced game. This means that you’ll have to place a high volume of wagers within a relatively short period of time. We’d recommend starting with a minimal bet unit of around $1.

Your choice of roulette game and iteration is also important for the effectiveness of the D’Alembert roulette system. For example, European roulette only features a single zero groove and offers an RTP rate of 97.30% Conversely, the RTP for American roulette is almost double at 94.64%, due to the addition of a second zero groove on the wheel.

So, picking European roulette iterations enables you to naturally retain more of your starting bankroll and optimize the efficiency of the D’alembert betting system.

Dozens and Columns D’alembert Roulette System

If you’re a less risk-averse player, you might consider applying the D‘alembert formula on roulette dozens and column bets. These wagers pay 2:1, allowing you to build profits faster. However, the odds of winning a single dozen or column bet are just 32.43%.

To reduce risk while still betting on dozens or columns, you can wager on two dozens per spin (e.g., 1-12 and 13-24). This increases your winning chances to 64.86%, but each win only returns half your total stake. This approach is ideal for those who prefer a lower-risk and are comfortable with a grind.

Craps is another casino game that’s suited to the D’alembert betting strategy. Once again, however, it’s important to focus on the game’s even money bets, namely Pass/‘Don’t Pass’, ‘Come/Don’t Come,’ and Odds.

These are just a few of the many bets available in craps. However, D’alembert is far less suited to other options, including ‘Hardways’ and ‘Any 7’, which have higher payouts but higher house edge and much lower probability of occurring.

Like roulette, the game of baccarat is incredibly fast-paced and frenetic. The game’s ‘Banker’ and ‘Player’ bets also boast respective RTP rates of 98.94% and 98.76%, meaning that it has obvious similarities with blackjack too. As a result, there’s some value in leveraging the D’alembert baccarat system when playing baccarat.

Once again, the key is to target the right wager types. The player or banker’s bet is the way to go; both payout at 1:1. However, a banker bet has a 5% commission as it is slightly more statistically likely to win due to the drawing rules.

This is another key consideration, as all negative progression systems require you to actively chase losses. This can place a significant strain on modest bankrolls, and you must be able to sustain losses in the pursuit of maximized returns. Losing streaks happen, but with the D’Alembert approach, a losing streak is seen as an opportunity to succeed.

There’s a reason why the D’Alembert system is synonymous with roulette, as it features a lot of even money bets. This is crucial as it optimizes your chances of winning and recovering previous losses. It’s important to always prioritize wagers that are as close to even money as possible.

Remember, most sportsbooks charge a commission that makes it tough to access even money wagers. So, you’ll often have to back outcomes with odds of +110 or greater. It’s important that you use detailed datasets and form analysis to make the most informed picks possible.

If you choose to use the D’Alembert strategy, it’s important to stick with it for the entire session, as switching strategies midway undermines its purpose. However, if you find that D’Alembert isn’t working for you, it’s perfectly fine to reassess and try a different approach after the session.
