The number the ball lands on is the winning number. The ball eventually comes to rest in one of the numbered pockets on the wheel. This is done by spinning the wheel in one direction and then releasing a ball into the wheel in the opposite direction. The roulette wheel is designed to produce random results. The ball eventually loses momentum and falls onto the wheel and into one of the 37 (in French/European roulette) or 38 (in American roulette) colored and numbered pockets on the wheel. The croupier then spins a ball around a wheel in the opposite direction to the spin of the roulette wheel itself. In the game, players can choose to bet on a single number, different groupings of numbers, the colors red or black, whether the number is odd or even, or whether the numbers are high (19-36) or low (1 -18). Roulette is a casino game named after the French word meaning wheel. But have you ever wondered how that wheel actually works? It turns out there’s more to it than meets the eye! What is roulette? Roulette is one of the most popular casino games in the world, enjoyed by millions of players every year.
