Roulette was developed around the turn of the century and is one of the most popular gambling games in the world. The Roulette wheels in Europe are numbered 1-36, and have a green zero section. The American version of roulette has a single zero and a double zero versus the French version with just a single zero. Roulette players often choose the bets they like to make and stick with them for a series of spins. Single numbers pay the highest, while either/or bets are lowest. The marked area of roulette is called the game layout, and you may place bets on any particular number, any 4 adjacent numbers, a column or a dozen bet. 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. In American roulette the addition of the 00 section greatly increases the odds in favor of the house. If the dreaded 00 is spun, the House keeps all the bets. Roulette is a banking game: all bets are placed against the house. " You may place roulette bets on the spin until the Dealer announces "No more 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.
