Dalembert Roulette Strategy

TOP SAFE ONLINE CASINOS ™

Dalembert mathematical roulette strategy is very simple and comes in several forms.

Idea behind Dalembert strategy

The classic version of Dalembert roulette strategy looks like that: suppose, you make a $1 bet on Red. If Red wins, the rounds ends and you get your $1 winnings. Then you start another round. You make another $1 bet on Red or Black. If your $1 bet on Red and Red loses, you must keep betting $2, then $4, etc. on Red. In other words, you must keep doubling your bet until you win. If your color wins, you get $1.

Idea behind Dalembert strategy

Why Dalembert strategy is not perfect

If casinos accepted unlimited bets, a player’s winnings would be 100% and the Dalembert strategy would be considered a strategy that never loses. Moreover, the player not always has enough money to allow him or her to fight for such small winnings over a long period of time. Still, despite the limitations set by casinos and budget limitations, Dalembert strategy allows many players win. From a mathematical point of view, Dalembert strategy has no contradictions in it. If a player makes 10 subsequent bets and loses, his loss is $1023. But the possibility of such a large loss is 1 to 1000. Thus, other 999 cases will be successful and secure a guaranteed profit of $1.

There are other doubling strategies which are very much alike. The only difference is how the player doubles his or her bet if the previous bet lost.

Dalembert strategy: Practical application

Suppose, the player decided to play 100 rounds by using Dalembert strategy. After the round is over, the player must stop. If the player wins the first round, he or she is likely to start another 100 rounds. An interesting thing is that a roulette ball had no memory and cannot remember which round stopped or started. Thus, the player can keep winning without even thinking about the fact than he or she will succeed in each of 100 rounds.
