I have an idea for a Line system. 
Waiting to a Line (1-6), (4-9), (7-12). . . .  etc.     20x has not appeared.  Then bet on these Line with the following progression:
10x 1unit
10x 2units
10x 3units
10x 5units
10x 6units
10x 7units
10x 8units
10x 9units
10x 10units
10x 11units
10x 12units
10x 13units
10x 14units. . . . . . . . . . . . . . . . 
if bankroll is bigger than the starting bankroll then restart
