There are 2 types of roulette, American and French (aka European roulette) 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. Each Player has a different colored set of non-value Roulette chips, determined by his/her purchase. 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. The dealer spins a small ball in the opposite direction of the spinning roulette wheel. When the roulette ball comes to rest in one of the slots, the dealer will call out the winning number and settle all bets. The roulette ball falls into one of the wheel's numbered compartments which determines the winning number. Unlike other casino games, roulette rounds go by quickly - just a spin of the wheel and the game is over. 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". 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.
