What is Online Roulette?

Online roulette is much like regular casino roulette, depending on which variation you choose to play. The only real difference is that online casinos use Random Number Generators (RNGs) for their games rather than a real croupier to spin the wheel, unless you are playing live dealer roulette.

As for the roulette rules, it is a game where players can bet on the outcome of a spinning wheel. The roulette wheel has 37 (European version) or 38 (American version) pockets on it. These are alternatively coloured red and black, with one or two additional green pockets.

A small ball is thrown on the spinning wheel to determine the winning number. Players can bet on one or multiple numbers, the colour, or the number being odd or even. Payouts are granted based on the odds of the selection.
