Numbers on a roulette wheel are represented by small circles that are situated around the wheel. The numbers 1-18 are located in the inner circle, while the numbers 19-36 are located in the outer circle.
The numbers 1-18 are also known as “natural” numbers because they can be found at every turn of the wheel. The number 19 is located in the center of the wheel and is considered to be a “lucky” number because it has never occurred in Roulette history to give anyone a loss.
