Had some luck with this one; 3 numbers bet-
* Bet first doublestreet that hits, the 3 numbers of the same color that has hit within that particular ds.
* If another color hits within the particular ds, bets are changed into the new color (3 numbers) and +1u bet
* progression +1u bet after 11 spins. (This progression is not perfect, but good enough in most cases)
restart at any hit, and pick a new ds.
only way it can bust is if progression goes to far, but that should be a rare event.
play for short sessions, use your common sense, don't be greedy!
cheers
