The game of Roulette is a gambling and casino game that allowed players to choose to place bets on either a number, the colour black or red, a range of numbers, or to say whether a number must be even or odd. To verify to see if a certain colour or number is chosen a croupier will spin the wheel in one direction and throws the ball in another on the tilted circular wheel. The ball then slows down until it stops and depending on whether it lands on a certain colour, number, even or odd then that is how you know whether you have won or lost the wager.
