This progression based Roulette strategy takes its name from the 18th century French Roulette theorist Jean le Rond d’Alembert. The method which is similar to the Martingale strategy whereby you increase your bet after a loss, is nowhere near as damaging on your bankroll if you hit a long run of losing spins.
Time to see the theory behind the D'Alembert theory, if it works, and is it worth using it.
HOW DOES THE D'ALEMBERT ROULETTE STRATEGY WORK?
SINGLE UNIT BETS ARE PLACED ON EVEN MONEY BETS USING THE D'ALEMBERT ROULETTE SYSTEM
Implementing the D'Alembert Roulette system is incredibly easy and consists of you placing a single wager on an even money bet. All even money bets are red or black, 1-18 or 19-36, odd or even, although mathematically these are not 50/50 bets they are as close as you can get when playing European Roulette as there is only 1 zero on the wheel, this means you actually have a 48.65% chance of winning.
Starting the strategy requires the even money bet, so I will choose to bet €5 on red, if this bet is successful then I will make a profit of €5 and start the process again by betting another €5 on red.
As with the Martingale, this strategy becomes a progression based method once you hit a losing spin, this system however requires you to bet another unit every time you lose rather than doubling up your bet like you would in the Martingale.
So I've bet €5 on red and lost, as I started with a €5 unit my second bet is now €10 ( if you had started with a €1 bet this would now be a €2 bet, if this loses then my following bet will be €15, all the time increasing by 1 unit for every losing spin. The interesting part to this strategy is when you again hit a winning spin, lets just say I win on the €15 spin. Rather than dropping down to the original stake of €5 like you would with the Martingale, you drop down 1 unit so the next bet would be €10.
You keep playing with this strategy all the time either increasing by a bet unit for a losing spin, or decreasing by a unit for a winning spin. When this eventually balances out and you get back to your original bet of €5 a spin, for every winning spin you achieved in that series you will have made €5 profit for each one, leaving you in profit for your overall session.
IS IT WORTH USING THE DALEMBERT ROULETTE STRATEGY?
THE DALEMBERT STRATEGY WILL PREVENT YOU FROM REACHING TABLE LIMITS LIKE THE MARTINGALE SYSTEM
Whilst there are certainly plenty of plus points about the D'Alembert strategy, it does also have its pitfalls. The steady incline of bets by one unit per time when losing will mean that it is very unlikely you will fall foul of reaching the table limit like you could do when using the Martingale system, however unlike the Martingale if you have a bad run using the D'Alembert method you can find yourself having to then get a lot of successful spins to get your money back, unlike the Martingale where as soon as you win you will be in profit.
Overall this is a good strategy if you had an endless amount of time and could wait for the good and bad runs to even themselves out so you ended up with a profit. The reality however is that sessions are often short and you have either some good luck or bad, so if you do manage to get some success with this system and get yourself into profit, then be sure to cash it out and try again another day.
