In this popular online gambling game, a player may choose to place bets on either a number, a range of numbers, the colors red or black, or whether the number is odd or even.

To determine the winning number and color, a croupier spins a wheel in one direction, then spins the ball in the opposite direction around a tilted circular track running around the circumference of the wheel.

The ball evenly loses momentum, and falls into one of the 38 numbered and colored pockets of the wheel. Players have a variety of betting options.

Placing ‘inside ‘ bets, is either selecting the exact number of the pocket the ball will land in, or a small range of pockets based on their proximity on the layout.

Players betting on the ‘outside', will select bets on larger positional grouping of pockets, the pocket color, and odd or even numbers.

The payout odds for each type of bet, is based on its probability.
