Another advantage of the game is the single zero, which allows for a better house edge, with a total of 37 numbers on the wheel and table layout. The wheel itself is sequenced slightly better, with no two big numbers stacked in neighboring ball pockets. For starters, European Roulette has a 2.70% native house edge which gives players a good margin to turn a successful bet. The European Roulette wheel isn’t too different than the American version, but it’s still a little more optimized.
