12 units on column 3

3 units on 0,1,2 section

4 units on the corners 4578, 10111314, 28293132 or 31323435 whichever suits you.

Leaves only 6 numbers flailing about to hurt you which i know is not good.

Total bet is 31 units to win 36 units.  I think it's not too bad at all.  Triple up when you lose and I go for 3 wins a session.

Comments, concerns, suggestions? All input is appreciation except blatant hate comments.  This is definitely not a holy grail but it's a nice little system for quick profits.
