Roulette players make bets by placing chips in various locations on the table. It is played in virtually every gambling house in North and South America and in Europe, where it is even more popular. Roulette uses a special wheel, a betting layout, and chips. On both wheels, you may think that there is no rhyme or reason as to how the numbers are arranged, but there is; the numbers are arranged this way so that the odds of landing on high, odd, low or even numbers are evenly distributed. All roulette players place their bets. The dealer spins a small ball in the opposite direction of the spinning roulette wheel. In roulette you can place bets until the ball leaves the track and falls onto the spun wheel. 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 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.
