This is a system played on roulette dozens and/or columns. You only need 8 units of a bankroll per session. We'll play with $50 units.

Since there are 3 dozens and 3 columns, the probability of each dozen or column coming up is almost 1 out of 3, with some zeros coming up now and then.

We will have just a 4 step progression of the type: 50, 50, 100, 200 or 5, 5, 10, 20 if you like or even as small as 1, 1, 2, 4. If you lose all 4 steps of the progression you lose 8 units and you start over again without waiting.

You bet on every spin on a Dozen or Column either 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.

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.
