I seldom play roulette but at this one B&M casino I pass by their two roulette tables to get to the Bac room.
I look all the time. Last night I saw 2 Back to back 29s and 27, 30 and 32 hit right after the 29s. Then I saw 20 hit followed by 18 and 23.
When I looked at the board I saw at least 4 times, numbers were hit that were connected to each other with at least 2 to 4 hits each fir each group.
