Roulette strategy - Dastin system

We divide a wheel on 5 sectors consisting of 7 numbers.

Group 1 = 35,3,26,0,32,15,19
Group 2 = 4,21,2,25,17,34,6
Group 3 = 27,13,36,11,30,8,23
Group 4 = 10,5,24,16,33,1,20
Group 5 = 14,31,9,22,18,29,7 (numbers 12 and 28 are not grouped)

Now we trace spins and we write down, what group of numbers drops out. We do it until will drop out four groups of five.

We do bets on group which and has not dropped out. It is possible to use a progression similar to these:

1 unit = 4 spins-28 or +28,21,14,7
3 units = 3 spins-91 or +56,35,14
5 units = 2 spins-161 or +49,14
7 units = 1 spins-210 or +35
8 units = 1 spins-280 or +14
12 units = 1 spins-364 or +56

Total 12 spins to strike 7 numbers.

Example. Following numbers have come: 0,13,18,3,22,23,4,6. These are groups 1,3,5,1,5,3,2,2.

From five groups necessary 1,5,3,2 have come to us. Therefore already on following rotation we put on numbers of 4-th group.

For example. Groups 2,28,1,2,3,4 have dropped out.

So, we have won on 6 spin. According to a progression, the prize makes 35 units. Further we should put on 5 group as groups 1,2,3,4 and 28 already have dropped out.
