Roulette was developed around the turn of the century and is one of the most popular gambling games in the world. It is played in virtually every gambling house in North and South America and in Europe, where it is even more popular. An American roulette wheel has an extra slot; 00. The French roulette wheel is divided into 37 slots, numbered 1 through 36, plus 0, there is no 00. The sections are numbered from 1 to 36, (half red and half black, half odd and half even) plus a green section marked 0. In a casino, the person who spins the wheel is called a croupier. When all bets are placed, the croupier spins the wheel and a ball bounces from slot to slot until finally coming to rest in one of them. The roulette dealer will exchange your chips for regular chips when you are done playing. Playing roulette you should give some indication to the dealer as to what value of chip denomination you prefer to be provided with. The roulette ball falls into one of the wheel's numbered compartments which determines the winning number. Roulette does not move at a quick pace, it is for a more relaxed crowd than you are likely to find at the craps table. 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. 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.
