No, no secrets to winning at roulette, just betting systems that don't work, but look as if they might to somebody who doesn't know anything about probability.
Other guy explained it pretty well about the 5.26% house advantage.
You can beat roulette by cheating, some ways to cheat it....
---Wheel timing computers that can predict where within an accuracy of ~10 spaces the ball will land by clocking how fast its spinning around the wheel, and how fast the wheel is spinning. Its totally high tech, totally real, and its totally illegal, it does work though.
---Creating wheel bias, by modifying the wheel, or making it crooked, you really cant do this without getting caught, it becomes very obvious
---Detecting wheel bias, while this isn't really cheating, its simply taking advantage of a defective wheel, it can work, however your just not going to find any defective wheels, the casinos know how to detect it also, and they will detect it before you do, and repair the wheel long before you even get to place a bet on it. You simply wont find ANY crooked wheels in a modern casino.
That's all i got, just don't play the game, you will lose money.
