The first step to understanding the game of roulette lies in knowing all the markings on the roulette wheel because the essence of the game of roulette is to predict where the small white ball lands.

The roulette wheel is a symbol of a casino. It often resembles a piece of art, and is extremely beautifully crafted. Many casinos use expensive heavy materials in their roulette wheels, which is why a wheel can weigh up to 100 pounds and cost many thousands of pounds. Typically, the outside rim of the wheel has pockets with a number written next to them. The pockets and their corresponding numbers alternate in two colours: black and red.

The outside rim also has one or two green pockets. These pockets have numbers 0 and 00 right next to them. The numbers on the rim are in random order. They do not follow any pattern or run consecutively or sequentially. Odds or evens also do not alternate according to some pattern.

At this point, you may be wondering how many numbers a roulette wheel has. The answer to this question depends on the country where a casino is located.

In the United States, including Las Vegas in the state of Nevada, Atlantic City in New Jersey, Indian reservations all across the country, and cruise ships that belong to American companies, you will most likely see a total of 38 pockets with numbers ranging from 1 to 36, one green compartment with 0, and one green compartment with 00. Such a roulette wheel is often known as the American wheel.

If you are going to visit a casino in Monte Carlo or another city in Europe or South America, you will see a wheel with one less pocket than on the American wheel. There will be numbers 1 through 36 and one pocket with a 0.
