The d’alembert system is a betting system
designed for binary option bets. It’s often
used in Roulette on outside bets, like Red
or Black and Odd or Even. For our demonstration
we’ll be focusing on betting red or Black
The d’alembert system is considered to be
safer than the martingale system, although
similar in style. Unlike the martingale betting
system, which we explained in another video,
the D’alembert system doesn’t require
you to double every time you lose. Instead
the player will go up in single units for
every loss and go down in single units for
The idea is to recoup any losses, whilst risking
little, and staying at fairly low bets.
For example, the player starts by betting
1. They then lose, so the next time they bet
2. If they lose another 2 times, for every
loss, they will increase the bet by 1 each
time. By the time they win, they have bet
4. Because they won, next round they will
decrease by 1 unit and only bet 3. If they
then win another 2 times, they will be back
to betting 1 once more. Since the bet can’t
go any lower, they will keep betting 1 until
their next loss.
You’ll notice that the increased bets after
each loss eventually lead you to earning back
more money when you next hit a win. The idea
is that losses can be braved for longer. In
our criticism of the martingale system, bet
limits mean that you will end up risking large
amounts of money, for a very small win. Here
it is very unlikely for you to go over the
bet limit since you keep your bets low and
build them up slowly.
The one clear downside to this is that wins
can’t make up for losses as quickly. With
martingale, one win will rectify all your
losses, here you will have to win several
rounds in a row to make up for your losses.
As with most betting strategies, the aim is
to keep losing to a minimum. These betting
systems are played out on binary outcomes
because the idea with any binary choice is
that their prevalence will even out over a
long enough period of time.
But there are a few problems with this. While
you can recoup your losses, there’s nothing
stopping you having too many short term losses
which drain your bankroll before you can recoup
your money. Another issue is the house edge.
The odds are never 50/50. In Roulette, the
presence of the green 0, skews your chances
on even money outside bets to 48.6% in European
and 46.37% in the American version. Meanwhile
Punto Banco has the standoff tie bet, removing
The logic behind this system is sound. with
infinite time and resources, and 50/50 odds,
this should result in a net gain. The problem
is that resources and time are always limited
and your chances are never truly 50/50.
In the big picture, there’s little gain
with this system over regular play.

us know how you get on in the comments. We
recommend trying it for short periods only
and getting out when you get ahead.
