Roulette is a glamorous, exciting game that's easy to play.

The typical "American" roulette wheel is divided into 38 slots which are numbered 1 to 36 plus 0 and 00. Even numbers are red and odd numbers black. 0 and 00 are green. Some casinos offer the "European Wheel". This wheel has only 37 slots. There is no 00.

After you place your bets, the dealer spins a small white ball in the opposite direction of the turning wheel. When the ball comes to rest in one of the slots, the dealer will call out the winning number and settle all bets.

These are the bets you can place and their corresponding payouts:

You can place as many bets as you like on a single spin of the wheel up to the table maximum.

Some casinos use a rule called en prison. When a zero or double zero hits, the player loses half the bet, or can let the bet remain in play, with the results to be determined on the next spin. This rule only applies to even money bets.

With the 38-number American wheel, the house has a big 5.26 percent edge. (Whenever 0 or 00 are hit, all bets lose.)

With the 37-number European wheel, the house advantage is 2.7 percent. In other words, on every $100 bet the house makes $2.70. With the en prison rule, this edge drops to just 1.35 percent.

Obviously you want to look for casinos that offer the European, single-zero wheel -- and many online casinos do. If you can find one that also offers en prison, so much the better.
