had some luck with this one....
you play one color, either red or black.
divide the carpet into four parts;
RED-groups
1-3-5-7-9
12-14-16-18
19-21-23-25-27
30-32-34-36
BLACK-groups
2-4-6-8
10-11-13-15-17
20-22-24-26
28-29-31-33-35
trigger: as one group hit (red or black, whichever color you choose to play) that group is bet. keep that bet until a second group of the same color hits, that group is also bet. and +1u bet. next do 3 spins , and STOP. if a third group is hit during two groups are bet, all bets are removed and the third group is bet,...restart and wait for a second group to hit...+1u bet when that happens, and do 3 spins, then STOP... (bet the next group that hits)..and wait for a second group...if you get a hit, all bets are removed and that single group is bet, ...wait for a second group to hit, and so on..
what i've seen is these groups tend to repeat very often, so hitrate should be decent...
more spins...
one bad session...
