Roulette is one of the most popular casino games among Iranian players, and it comes in a variety of different variants. European Roulette is the most common version in Iran, with its 37-slot wheel and single green zero pocket. American Roulette is slightly different to its European cousin, as it has a 38-slot wheel and two green zero pockets (double and single). Double Ball Roulette is a more modern variant, using two balls instead of one, thus allowing for multiple wagering options such as ‘Double’ and ‘Special’ bets. French Roulette is the oldest version of the game and features some of the most favourable odds to the player.
