I don't play roulette systems but is fun to fool around with them.
Pick 12 sectors.
0
1
2
3
4
5
6
7
8
9
10
11
When you get your first outcome you make a cross at that sector and the others which alternate from that position.
0 x alternate
1
2 x is the outcome
3
4 x alternate
5
6 x alternate
7
8 x alternate
9
10 x alternate
11
Cover all that does not alternate and play 111 on a win and plus stop and if a loss continue with 234 if a win move down two steps and play until plus or break even or one three losses move up in the latter - progression 1 1 1 2 3 5 8 13 21 34 55 89 or play for two in a row 1 1 1 1 2 2 3 3 5 5 8 8 13 13 21 21 34 34 55 55 89 89 and use it as a step latter so move forward on a loss and back two steps on a win and stop at break even or at a win.
HEHEHE it tank on the secound attempt :twisted:
