The Roulette Wheel

A standard casino roulette wheel is made of polished wood and is nearly 90centimeters (3 feet) in diameter and weighs about 45 kilograms (100 pounds)

The numbers on the roulette wheel are not in sequential order. The main pockets of a roulette wheel are numbered from 1 to 36 alternate between red and black. The numbers are not arranged in high-low order nor are they placed randomly. The numbers are ordered in a way as to achieve a mathematical balance between high and low, red and black and even and odd, with red and black numbers alternating and with red numbers positioned opposite the black number.

There is also a green pocket numbered 0 and a second pocket marked 00 in most roulette wheels in the United States ( not in Europe ).

The main difference between the European and American Roulette Wheel is the 0s. The European RouletteWheel with only a 0 and no 00, favor the gambler and alters the house edge in comparison to American Roulette. This 0/00 discrepancy changes the house advantage from 2.7 percent with the European Wheel to 5.26 on the American Roulette Wheel which have both the zero and the double zero.

The American Roulette Wheel 

The  American Roulette wheel has 38 pockets ranging from 0, 00, and 1 through 36. The 0 and 00 pockets are green, while the other 36 pockets are evenly divided between red and black.

In the American Roulette wheel, the number face the outside of the wheel. Usually, pairs of odd numbers alternate with pairs of even numbers. The 0 and 00 are opposite each other and every red number is opposite a black number. 

The European RouletteWheel
