# D’Alembert

Born in 18th Century France just like the Martingale betting system, the D’Alembert betting system is a method that offers a cohesive strategy for wagering, as opposed to most bettors who have no real method to their madness.

Like Martingale, the D’Alembert betting system, which is mainly used in blackjack and craps but can also be applied to sports betting, asks a bettor to think of a betting session as something larger than just a series of individual bets.

Like Martingale one more time, mathematical concepts underpin the D’Alembert system, giving math geeks the opportunity to include algebraic equations in their sports betting conversations.

But despite these apparent similarities, Martingale and D’Alembert could not be more different in their risk tolerance levels. Martingale is the crazy one, a Russian roulette specialist, whereas D’Alembert just likes to sit down and play for a while without totally losing his shirt.

How the D’Alembert Sports Betting System Works

The D’Alembert betting system requires that a bettor think of each bet in terms of “units.” Until you have decided what a “unit” is, you cannot play according to the D’Alembert rules.

For instance, if you are in the habit of betting \$20 on sports games, then you could decide that \$5 is one unit, or you could decide that \$10 is one unit. But decide you must, because adding and removing these units from your bet sizes will be the essence of how D’Alembert works.

The value of the units should naturally depend on your bankroll. If you have only \$100 total to bet, you should probably use \$5 units. If you have \$1,000 in your account and plan to see where you can go with it, \$10 units will give you more excitement and more upside.

Once you’ve assigned a proper per unit value to your betting session, using D’Alembert is pretty simple:

After each win, you decrease your bet size by one unit. So if you just bet \$20, and you’re playing with \$10 units, and you win, your next bet should be sized at \$10.

After each loss, you increase your bet size by one unit. So if you just bet \$20, and you’re playing with \$10 units, and you lose, your next bet should be sized at \$10.

Rinse and repeat.

Rinse and repeat.

Over time, because of the vig that the house takes for allowing you to make each bet (remember that a sportsbook only pays out \$18 for every \$20 you win, but when you lose, you lose the full \$20), you will lose money if you play D’Alembert for a long enough period of time.

But you won’t lose a tremendous amount of money. And in the world of sports betting, sometimes not tanking your whole account can be considered success.

Low Risk, Low Reward: Playing to Play

The D’Alembert sports betting system is a viable option for sports bettors who want to have action on games, but don’t want to risk losing a lot of money. D’Alembert can help you keep your account alive while you enjoy watching the games.

It’s a low risk strategy, as far as sports betting systems go. So long as you pick an appropriate unit size, as described above, you should be able to stay in the game long enough to have fun. Blackjack players who practice this system can play for hours relatively inexpensively in most cases.

The D’Alembert sports betting system is also low reward, though. After all, after every win, D’Alembert requires that you take money off the table for your next betâ€”this means that if you do hit a hot streak, you’re not going to get “full value” for your hotness.

On the upside, if you do hit a hot streak early on in your betting session, for example if you hit your first 5 picks, practicing the D’Alembert sports betting system is effective at giving you that special tingling sensation of knowing that you are now playing with the house’s money.

An exhilarating feeling indeed!
