Sharp, It's a long ways from a classic system. You can call it a system if you'd like, as the word system is basically the same as saying strategy or method, but they weren't trying to beat the random game of roulette. They were going after the wheel! Such defects have been around and taken advantage of for hundreds of years. Numerous cases have been widely reported on, documented in gaming journals, risk conferences, bood etc. They're even discussed somewhat openly by wheel engineers. Writing numbers to find biased wheels is a very old "system," but it does work. What's funny though is you could tell hundreds of people how to do it, but most would fail, even if they found a biased wheel.
