I just stumbled across the following article: http://genuinewinner.com/science.html, which makes the following claim:
There's no way of knowing exactly which number will spin next. And there's no way of knowing exactly which AREA of the wheel will spin next. However, you can determine, with enough accuracy to beat the house edge, which areas of the wheel is most likely to spin next. This is achieved by understanding the physics of roulette wheels, what patterns are likely to occur over the long term, and how to identify and exploit those patterns.
Is it true that if you are astute enough, you can gain enough of a rough idea of where the roulette ball will land, that you can overcome the house edge?
