Like most casino games, roulette has different rules in the world. Most online casinos offer at least a couple of different versions of roulette, and this is one of the advantages of playing online compared to traditional casinos: You can choose which version to play, no matter where you are geographically.
The American roulette wheel has two green boxes, one with a zero (0) and one with a double zero (00), in addition to the numbers from 1 to 36, for a total of 38 slots. You may come to think that having an extra box is a good thing, but in reality is just the opposite. Your odds of winning decrease as a box more, not to mention the fact that, when the ball stops on the green boxes, the outside bets are automatically considered losers. Have two boxes that automatically cancel a large number of bets is not an advantage.
European Roulette is a variant of roulette has only one green box, the one with a single zero (0). The odds of winning are better, rising by several percentage points compared to the American roulette: the house edge (and thus the disadvantage of the player) in European roulette is 2.6%, while in American roulette is 5.2%. Most European websites that offer online roulette have this variant among those available.
This version of roulette, which is the European roulette wheel includes an additional rule, the “En prison”, which provides half of your wager “equal” (red / black, odd / even, etc..) Is returned in the event that is extracted just the number 0.
