There are 2 types of roulette, American and French (aka European roulette) The standard American casino roulette wheel contains two green slots: 0 and 00 (many European wheels eliminate the 00, which creates more favorable odds for players) 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. The ball stops in one of the numbered pockets of the Roulette wheel. European wheels have only the 0 green section. All roulette players place their bets. The dealer spins the roulette wheel in one direction and the small ball in the opposite one. In roulette you can place bets until the ball leaves the track and falls onto the spun wheel. The winning roulette number is marked by the Dealer. Unlike other casino games, roulette rounds go by quickly - just a spin of the wheel and the game is over. After all payoffs have been made, the Dealer will announce "Place your bets. You should remember to exchange the colored non-value Roulette chips for valued gaming chips prior to leaving a particular Roulette table. 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.
