Well now, this system is based on VARIANCE (if i understood the term correct) it's 15 numbers bet, played with progression.
TRIGGER: Wait for a series of minimum 3 (or more) of the same color. When a switch of color comes, bet all numbers (of that new color hit) all EXCEPT the 3 numbers within the particular Doublestreet hit. (15 numbers bet)
IF any of the three unbet numbers hit, STOP, and takeloss.
Progression: Double bets after 2 spins- This progression is not perfect, (and it's not ment to be!)
Bankroll needed: 300-500u played with 1u bets
First test was played with 1u bets
3/3 Games won
IF any of the three unbet numbers hit, STOP, and takeloss. (This is only an option, maybe not good if progression goes too far, then it's better to continue, perhaps)
4/4 Games won
5/5 Games Won
