Roulette players make bets by placing chips in various locations on the table. Roulette is a unique table game as it has a mechanical device as the main element of the game. The Roulette wheels in America have a green zero and double zero, giving the American casinos the twice house edge. Once the bets are placed on the table, a small ball is released on to the spinning Roulette wheel, in the opposite direction to the spin. Before you can place your bet on a roulette table you first have to get special roulette chips from the dealer at the table. European wheels have only the 0 green section. 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 dealer spins the roulette wheel in one direction and the small ball in the opposite one. The ball slows and eventually stops in one of the numbered pockets in the Roulette wheel. Numbers 1-18 are considered the lows numbers, 19-36 are the highs. Losing roulette bets are collected and winning bets are paid. Wait til the dealer says "place your bets" before putting any roulette chips down for the next round. 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.
