The d'alembert roulette strategy is a system to increase a gambler's chances of winning. The user of the system adjusts the bet each time according to the result of the previous round. As a result, the player can make up for previous losses and take small profits each time.
The D'alembert roulette system was invented by a well-known scientist, Jean le Rond d'alembert. He lived in France in the 18th century, at the very time when roulette became a giant hype there. D'alembert calculated a clever strategy for the new game of Chance, which became a big hit and also became popular in the banking world. And now (more than two centuries later) the d'alembert roulette strategy is still one of the most played roulette systems .
How does the d'alembert strategy work?
The player starts with a bet that is about 1 percent of the total budget (bankroll) for the game session. Let's say, $1. With a 50/50 bet, that bet is doubled if the player wins. This way, he or she will collect a small profit of $1 every round.
Only when the player loses does it change the bet. The player deposits an additional initial unit, from $1 to $2. If that bet loses again, an additional bet is added, namely $3. Every time the player loses, the bet increases: from $1 to $2 to $3 to $4 to $5, et cetera. In the classic d'alembert roulette strategy, a maximum bet of 10 times the initial bet applies, so $10
Does the player win again after losing? Then the player takes one initial bet from the next bet, and continues to do so for as long as the bet wins: from $10 to $9 to $8 to $7 to $6, et cetera. The bet can never fall below the initial bet of $1. And so the bet changes every round between $1 and $10, depending on whether the previous round was won or lost.
