Gambling would be pointless without winning! People who gamble are always prepared to lose, but winning is the sweetest piece of this cake, no wonder every gambler tries to find a way of winning more! You have heard about different systems elaborated for different games before, and now we will tell you about one of the three betting systems popular among people who play Roulette.

The D’Alembert betting system got its name from its inventor, French mathematician Jean le Rond d’Alembert. This Roulette strategy is based on his mathematical theory. If you come to think of it, you will see that this system is a variation of the famous Martingale system – it involves step-by-step increasing or decreasing the size of bet. Nevertheless, many people call it a pyramid system. It is usually applied to even-money roulette bets (so-called outside ones). If you wish to apply the D’Alembert strategy, you have to add or subtract one unit after each bet. If you lose the bet, you add one unit to the bet to come; if you win the bet, your decrease the bet to come by one unit. Due to this pyramid strategy you never break the table limit and never lose large sums of money. Unlike in Martingale, here you do not have to start with a very low initial bet. Let us view an example. If you bet $5, your betting progression will look like this:

$5 > loss > $6 > loss > $7 > win > $6 > win > $5 > win > $4.

Dalembert betting strategy became so popular among all gamblers because of the following fact: if the number of your wins equals the number of your losses in the Roulette game cycle, your net gain equals the number of wins. Experienced or aggressive players tend to increase or decrease your bets by 2 units each time. They risk more but they double the net gain as well.

Reverse D’Alembert System

Just as with all other systems, there is the Reverse or Contra D’Alembert system. Its basic mechanism is evident: you add one unit to the next bet after each win and you deduct one unit after each loss. If you bet $5, your betting progression will look like this:

$5 > loss > $4 > loss > $4 > win > $4 > win > $5 > win > $6.

Many gamblers boast of winning round sums of money with this system. Well, it is simple and efficient, but the major problem with it is determining when it is time to abandon a winning streak. Professionals recommend you to stop increasing the bet and return to the initial betting after 3 or 4 wins in a row.
