Traditionally roulette has been played in regular offline casinos. The United States adopted their own version of roulette, but the French version is still played time to time in Las Vegas. The outcome of a game of Roulette is determined by where the ball stops on the Roulette wheel. The wheel is divided into 38 (American) or 37 (European) sections, each of which has walls to hold a small ball where it lands after the wheel is spun. Single numbers pay the highest, while either/or bets are lowest. The zero and double zero numbers are in green and on opposite sides of the wheel, the colors and odd/even numbers alternate, and the numbers themselves are randomly distributed. All roulette players place their bets. After all bets are placed, the roulette Dealer spins the wheel in one direction and the ball in the opposite direction. If the dreaded 00 is spun, the House keeps all the bets. Even if you play it safe and bet red/black or even/odd, casino roulette is a lot of fun. Losing roulette bets are collected and winning bets are paid. Once the roulette ball has found its slot, the dealer will call out the winning number and place a marker on that number's spot on the layout. Wait til the dealer says "place your bets" before putting any roulette chips down for the next round. When you finish beating the house at roulette, you will have to ask the dealer to "color out" for you, the dealer will then take your chips and give you casino checks which you may then use on other games or cash out at the cashier.
