So what is online roulette? Generally speaking, online roulette is a game that allows you to bet on where a little ball is going to land. Okay, that may be the simple definition, but that is pretty much what the game is all about. The main components of any roulette game are the wheel, the ball, and the able where you will place your bets. Once you are ready to go, the dealer will spin the wheel which will carry the ball around in circles until it stops. Of course, you have a certain amount of time to place your bet as well. But once the dealer waves their hand over the table, all bets are off.
