Online roulette has three versions - French, American, and European roulette. While the basic principles of playing this game remain the same, every version differs from the other in terms of odds and payouts. Therefore, since American roulette has an additional slot for (00), this game has lower odds than its French and European counterparts. Both the latter versions have 37 slots and no double zero. That said, many gamblers consider French roulette better than European roulette for its 'in prison' rule. Here, the player loses only half his even/odd stake if the spin is a zero. Lately, many studios have begun rolling out newer versions of this game. For example, you can play Lightning Roulette on some of the finest gambling websites in Ontario. There are other versions as well, such as Mini Roulette.
