This variant has 38 pockets and an additional double zero. It means a tougher sport with a higher house fringe of 5.26%. The American roulette wheel has a extra harmonious format than the European wheel, which has a very random wheel format. Since the American wheel has 38 pockets and even numbers, the green 0 and 00 pockets are positioned directly reverse one another. Similarly, numerical neighbours (like 1 and a pair of, three and four, and so on.) are also positioned opposite one another in opposite colors. Inside bets are placed on particular numbers or small groups of numbers.
