I named the program RouletteHemis and I was the only user for a couple of years. I wrote my in-house roulette software to analyze the distribution of numbers between the inner half and the outer half of both types of roulette wheels. It was likely that the casinos had no knowledge of such phenomena. To my (belated) dismay, the ratio was 80% to 20% biased towards the outer hemisphere! Actually, two roulette dealers - a woman and a man - shifted at the table during that continuous run! So, it was not a so-called roulette dealer's signature! It was a malfunctioning of the roulette wheel. I tracked the spins at a roulette table in Atlantic City. The next number should be FFG-equally distributed between the two wheel hemispheres. In other words, we deal with the inner half and the outer half of a roulette wheel (since the wheel is far from being a sphere!)

The last number drawn, plus 9 numbers to its left on the roulette wheel layout, plus 9 numbers to the right on the layout make up the inside hemisphere of the roulette wheel the other 19 numbers make-up the outer hemisphere. There are 38 numbers in double-zero roulette. We can divide the roulette wheel in two sections based on the last number drawn. The wheel was malfunctioning, anyhow, I think. Probably the deflectors of the roulette wheel were worn out. I noticed wheel bias regarding the jump from the previous slot to the next roulette number drawn in the next spin. It happened at a roulette table at Taj Mahal casino, Atlantic City, in July of 2000. It escalated to proportions experienced in police dramas on television. This entire story started by simple chance in 2000. Published by Ion Saliu on October 21, 2010.
