Roulette is a casino game named after the French word meaning little wheel. In the game, players may choose to place bets on either a single number, various groupings of numbers, the colors red or black, whether the number is odd or even, or if the numbers are high (19–36) or low (1–18).
To determine the winning number and color, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the circumference of the wheel. The ball eventually loses momentum, passes through an area of deflectors, and falls onto the wheel and into one of 37 (in French/European style roulette) or 38 (in American style roulette) colored and numbered pockets on the wheel.
I like to play soccer...))),but if we talk about online games, I would prefer some simple games, like for example slots or 'thunderstruck 2 slot'.
