Traditionally roulette has been played in regular offline casinos. The Roulette wheels in America have a green zero and double zero, giving the American casinos the twice house edge. Roulette players can bet on one, two, three, four or six numbers; or they can choose to bet red or black; high or low; odd or even. 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. 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. Winning bets are determined by the numbered slot in which the ball comes to rest. Roulette is a banking game: all bets are placed against the house. 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.
