Roulette is a classic casino game that comes with an interesting betting system and simple rules. It's a very popular game among both professional gamblers and recreational players. In roulette, players wager chips based on where they think the ball will land on the wheel. The wheel is spun in one direction and the ball is set in the opposite direction. When the wheel comes to a stop, the ball is resting on a number. There are a total of 37 numbered slots, with 18 red numbers, 18 black numbers, and 1 green zero. If the ball lands on one of your bet selections, you win!
