I try 3 instead of 4. I saw in the stats of the roulette tabele (last 50 spins) that the second dozen only hit 23% of the time, so I avoid it teh seocnd dozen . Instead of dozens, I note the columns, as it gets totally random. I don't like the Martingale system, but I tried a progression of 1, 2, 5. but i suggest to avoid martingale or tripple. I alway stop at a 3-5 unit win and move to the next table. Alternatively, if the roulette trigger tool gives me a 3x3 trigger on evens, or a 3x trigger on two dozens/columns (like 1,23, 1,2,3), I play that sequence instead. So basic i play DC trill trugger alert and then switch back

Here is my the latest play
