I know of these methods to beat the roulette wheel. I know the mythical story also about the person that tried to beat the roulette wheel and didnt succeed. After he found out it couldnt be beated, it drove him insane and he committed suicide. This is a famous story if i am correct. Fun fact is, that with my research into the roulette tactics i came across a website that sells machinery that are able to see where the ball will land. After i found out, i studied these methods, and it seems to work and be possible!
Anyhow, it isn't really forbidden by law. The laws internationally got adjusted right now while we speak towards making this forbidden. But laws have gotten older than evolution. Basically it is possible to beat the wheel with a very accurate calculation...
I knew this longer, but i didnt found it fitting the forum as it is an abusive way of play. It kinda is not what this forum is meant for. And i dont think that it will be useful to advertise for these methods of beating the wheel.
Anyhow, i have a Youtube video here where you can see how this thing occured.
