This is a system for roulette which is played on the dozens and/or columns. You only need 8 units of bankroll per session. I play with $50 units, so a total bankroll of $400 per session.

There are 3 dozens and 3 columns as can be seen on the table below:

The probability of each dozen or column coming up is almost 1 in 3, with the exception of some zeros coming up now and then.


We will use just a 4 step progression, in my case using $50 units, the progression looks like this:

50, 50, 100, 200

It depends on your unit size, it could be 5, 5, 10, 20 or even as small as 1, 1, 2, 4.

If you lose all 4 steps of the progression you lose a total of 8 units and you start over again without waiting.

How to bet

You bet on every spin on a Dozen or Column. The choice of which one is up to you, you can bet on a random choice of yours or on the one that didn’t show up for the last 2 spins, or on the one that is different from the last 2 different dozens or columns.

Either method will yield the same results, since every outcome in roulette does not depend on previous spins and is totally independent of them.

You bet using the progression above, for example using $50 units as I do, I bet $50 on a dozen for my first bet, if I lose I then bet $50 again on the next bet. If i lose again I then bet $100 on the next bet, if I lose this I then bet $200 on the next bet, if I lose this then the session is over with a loss of 8 units.

With the exception of the first bet, if you win, you get a profit of exactly the amount you have bet during the progression. If you win at your very first bet, you get back double your bet.

With lots of wins at your first bet, and hitting your dozen or column within 4 bets and with the likelihood of it showing up once every 3 spins, you can win a lot with this system even on the longer run.

But you never know when the table will turn totally against you, as the outcome is random. So, stop when you have some decent profit and go home and enjoy your profits.

The table below shows the profit and losses at each stage of the progression:

Spin No. Bet Net loss Gain Net profit
1 $50 $50 $150 $100
2 $50 $100 $150 $50
3 $100 $200 $300 $100
4 $200 $400 $600 $200
