There is no system that will allow you to win money over the long run. The most important thing I've learned is that you cannot beat roulette. I've also got a section on the systems that people use to try and beat the game. I've tried to cover useful things like the types of bets you can place and the probability involved in the game.
This is my little hobby website about roulette. Other games like craps and blackjack rely on dice and a deck of cards for randomness, but roulette is the only one that puts the result of each game in the hands of physics.
I think it's the best game in the casino.
