After spending nearly ten years as a Croupier in various capacities and then spending a further ten years examining and then analysing roulette then I can see the mechanics of how you can track a roulette ball. Imagine if we were to take two moving objects that were both travelling in the opposite direction. These could be two moving vehicles on a road many miles apart travelling towards each other. Let us also imagine that the actual road is the numbers that the ball passes over on its way to its final destination.
If point A and point B were say 1.7 miles apart and two cars were heading towards each other then how long would it take before they met? Clearly we don’t have all of the available data because we do not know the speed of both of the cars. Once we know the speed of car A and the speed of car B then we can ascertain where point C is where they will meet. Except there is a further dynamic involved because one of the vehicles is not travelling at a constant speed all the time but in actual fact starts out at a fixed speed and continually de-accelerates until the point where the two meet.
Rather than trying to figure out the rate of de-acceleration then you can basically find that out by recording data from past spins and comparing results from spins with almost identical speeds. These are the mechanics of ball prediction and the casinos know that it is possible. If it wasn’t possible then the roulette wheel manufacturers wouldn’t try so hard to make their wheels as random as possible.
