Whoever played roulette longer would notice that the dealer somehow sometimes is stuck in some section or that for some time some numbers come more often.
When we look hot numbers on the display board it is in usual for past 300 spins.
If we divide it by 37 we get that in an average each number should hit 8.1 times.
If on the board we see say some numbers past 300 spins come 9-12 times it is normal, it is still within one standard deviation. But if we see it say 17-20 times it is much more.
So what if you come to the table one day and it shows the number as 1 and 2 at about 17 hits, next day other 2-3 numbers 18 hits, next day again other numbers. For example, each day or say a few days in a week some different numbers hit 15-20 times.
Can it be a coincidence?
What if it is static electricity and very light in weight roulette balls?
Many casinos have carpets, dealers may have some sintetic clothing, come to the wheel charged and leave some charge on the pockets or wheel section where they pick the ball.
Did anyone try to charge the pockets with static electricity?
What is your thought on this?
