There are 2 types of roulette, American and French (aka European roulette) Most casinos have 00 on their roulette wheels to increase the odds to their advantage (American Roulette) 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. The roulette chips are worthless at the other tables in the same casino, so do not bother trying to stack them under your blackjack chips or anything foolish like that. If the roulette ball lands in the 0 slot, the game ends and all players receive half their original bets back. Roulette is not as popular in United States casinos as it is in Europe. Even if you play it safe and bet red/black or even/odd, casino roulette is a lot of fun. Roulette is a banking game: all bets are placed against the house. 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. " You may place roulette bets on the spin until the Dealer announces "No more bets". 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.
