# D'Alembert Strategy Simulation: Our Bankroll Results After 30 rounds

D'Alembert Strategy Simulation - what does our bankroll look like after 30 game rounds? Find out how to win with the D'Alembert system by making small, consistent, low-risk wins
The Dâ€™Alembert system is well-known for being the simplest and lowest risk progressive roulette strategy in existence, but whatâ€™s it actually like to play it? We decided to give it a try at Pots of Gold, using an established testing format â€“ but first a recap on how it works:

• How much we made after 30 game rounds
• Detailed execution of the D'Alembert roulette strategy
• Whether the strategy is worth your time and money

## D'Alembert Roulette System Explained

Dâ€™Alembertâ€™s system requires you to increase your bet by ÂŁ1 when you lose, and decrease it by ÂŁ1 when you win. Itâ€™s that simple, so what happened when we tried it out with a ÂŁ100 bankroll and starting bet of ÂŁ10? Let's find out:

#### Round 1

• We bet on evens, and our first of three simulations kicked off with a 33, taking us down to ÂŁ90
• Our bet was therefore raised to 11 and a 9 came up, leaving our bankroll at ÂŁ79
• We therefore bet 12, and a 2 came up â€“ taking us back up to ÂŁ91, lowering our bet to ÂŁ11
• A 5 was spun, leaving us with ÂŁ80
• A ÂŁ12 bet wasted on number 11 left us with just ÂŁ68
• We now bet ÂŁ13, and things looked up with a 12, taking us to ÂŁ81
• A ÂŁ12 bet and the appearance of 36 raised our bankroll further, up to ÂŁ93
• A zero then left us with ÂŁ82
• Another ÂŁ12 bet left us with ÂŁ94
• Finally a 4 was spun, taking us to ÂŁ105

Not a bad result, but more was to follow in the 2nd simulation:

#### Round 2

• A 6 took us to ÂŁ110
• ÂŁ9 bet on a 3 left us with ÂŁ101
• Back up to ÂŁ10, our stake brought in another tenner with a 12 on the wheel
• A ÂŁ9 bet led to a loss of ÂŁ9 when an 11 came up, taking us down to ÂŁ102
• A further ÂŁ10 was lost when the number 1 appeared
• Then a 4 came in, taking us to ÂŁ103
• A ÂŁ10 bet yielded a ÂŁ10 win when 28 came up, leaving us with ÂŁ113
• Then a 30 was spun leaving us with ÂŁ122
• ÂŁ8 bet on number 3 left us with ÂŁ114
• Lastly, a ÂŁ9 bet on the number 2 left us with ÂŁ123

With 2 out of 3 simulations yielding us a decent overall result we were delighted, but the law of averages says you canâ€™t win all of the time, so what of our final test?

#### Round 3

• We started badly with a 27 taking our bankroll to ÂŁ90.
• An increased bet of ÂŁ11 and the appearance of the number 12 changed all that, getting us up to ÂŁ101.
• An 8 took us to ÂŁ111
• A 14 left us at ÂŁ120
• We now bet ÂŁ8 and spun a 9, leaving us with ÂŁ112
• A 6 got us up to ÂŁ121
• A 15 took us to ÂŁ113
• The zero was then spun â€“ no good for us as this was a European game so we lost the whole ÂŁ9 stake, taking our bankroll to ÂŁ104
• A loss of ÂŁ10 when the 1 came up left us with ÂŁ94
• Another loss of ÂŁ11 on the number 11 finally left us with just ÂŁ83.

The total outcome was ÂŁ302 for ÂŁ200 wagered, and this is a classic Dâ€™Alembert outcome: A small increase for a small amount of risk.

## Does the D'Alembert work?

The great thing about this strategy is that two subsequent spins will always produce a positive result 75% of the time.

In the above example, a win and a loss will leave you with ÂŁ101; a loss and a win will also leave you with ÂŁ101, and two wins will leave you with ÂŁ119 â€“ so the advantages are clear.

Youâ€™ll find that your overall result tends to cluster around the ÂŁ100 mark, so the amounts you win wonâ€™t be huge. But any savvy roulette player will tell you that you should be looking for small consistent long-term net wins which ultimately consolidate into solid long-term gains, and this system is a great way to do that.
