Roulette "Chasing" -- betting on the imperfection of the wheel... I've come up with a simple idea called "chasing". First off lets look at the fact that a roulette wheel is NOT PERFECTLY random. Small dents, unequal traction, etc. These imperfections may only give a .01% improvement on certain numbers, but stay with me here.. You would think to take advantage of this .01%, you would have to somehow figure out which numbers are insignificantly favoured by imperfections. It would be nearly impossible to choose the right numbers. BUT ..Simply betting on the previous "winning number" ensures that you are taking advantage of these dents/scratches by letting the results determine your future odds! If this doesn't make sense, let me use a very simplified roulette wheel with only 4 numbers 1,2,3,4. Let's say theres a large dent in this exaggerated example, causing the ball to usually land on 3. Let's say this dent is so severe, it causes 3 to win 60% of the time. The dealer spins the wheel and drops the ball. It lands on 3. So bet on 3 next time. It lands on 2.. So bet on 2 next time. Usually you will be forced to bet on 3, and only sometimes on 2. This will be MUCH more profitable than randomly picking 1-4. By "chasing", you are letting the winning numbers tell you what works. Sometimes its wrong, but in this case it's 60% right! Anyways, this is the extremely simplified version of what "Chasing" is. Instead of betting on 3 60% of the time, you're going to be betting on say, 31 2.7% of the time (as opposed to 2.6% or whatever it is), because 31 is coming up SLIGHTLY (0.01%) more often, and so you are betting on it more. By chasing, you are betting WITH the imperfection of the wheel. With 36 numbers to land on, and with dents/scratches not even visible to the naked eye, this advantage is EXTREMELY small, and by no means signifcantly profitable (or is it?). Now heres my question: on a European Wheel with a 2.6% house advantage, do you think a wheel might be flawed enough to have a 3% "chasing advantage"? Or is my initial estimate of 0.01% much more accurate? It's also interesting to see how deliberately damaging a wheel could make profits with chasing very possible (and no need to even predict the track of the ball). It would be illegal but interesting to think about..
