Roulette

Roulette is a casino game named after a French diminutive for "little wheel". In the game, players may choose to place bets on either a number, a range of numbers, the colours red or black, or whether the number is odd or even. To determine the winning number and colour, a staff member spins the roulette wheel in one direction, then drops a ball in the opposite direction inside the wheel. The ball rolls around a tilted track running along the circumference of the wheel. The ball and wheel eventually lose momentum and the ball falls into one of the pockets on the wheel. Each pocket has a number and colour. The winning bets are the ones that were relevant to the number and colour of the pocket that the ball landed in.

The higher the odds are of not winning the bet, the greater the reward if it is won.
