1-3-2-6 System

1-3-2-6 System is a positive progression system similar to the Paroli System. The main premise of this system is that you may win four times in a row. In the first step you bet 1 unit, in the second - 3 units, in the third - 2 units and finally in the fourth step - 6 units of money. If you lose at any step you start all over again at 1 unit (then 3 units and so on). The odds should be close to 2 and the winning chance of a single event should be close to 50%.

Example:

The odds of every event are equal 2.

You bet 1 USD. You win 2 USD.
You bet 3 USD (you have to add 1 USD extra). You win 6 USD.
You bet 2 USD (you take down 4 USD from the betting amount). You win 4 USD.
You bet 6 USD (you have to add 2 USD extra).

It is clear that if you lose the first bet you will lose 1 USD. If you lose your second bet you will lose 2 USD (1 from the first bet and 1 from the second bet). If you lose your third bet you will win 2 USD. If you lose your fourth bet you will be breaking even on the whole.
