Roulette is available in several variations at many online casinos. Each version involves a table with a selection of betting options printed on it. These are usually displayed on a green background. The roulette wheel shows all the numbers involved in the game.
A small ball is then spun in the opposite direction to the wheel spin. It then stops on a number. All winning bets are then paid out, with the house retaining all losing bets.
American roulette has a single zero and double zero occupying two spaces of the wheel. This means the house edge is higher at 5.26%.
European roulette is more attractive as it does not have the double zero in play. This reduces the house edge to 2.7%. There are two versions of European roulette – one with a standard table and another with a racetrack. The latter includes additional bets such as orphelins.
French roulette may also appear, offering the opportunity to receive half your losing bet if you are incorrect at guessing an even chance bet. If you guess odd and the ball falls on even, 50% of your bet would be returned.
Many online casinos offer standard roulette games, with some adding live roulette to the mix as well.
