If you can avoid gambling on American roulette you should do so as your gambling odds are reduced with the extra number; at online casinos it is possible to avoid but some gambling clubs or cruise ships and the like often give you no choice. Gambling on roulette is simple enough as all you are doing is try to predict the result of the spin of the wheel but the attraction of roulette gambling is that you have an enormous variety of bets ranging from the low risk and low reward red/black or odd/even bets right up to the high risk high reward single number bets and many who like gambling on roulette will combine many bets on a single spin. Gambling on roulette has no skill and is a gambling game of pure chance and one of the unique features of the game is that there are no good bets or bad bets that provide better or worse odds relative to the number of numbers backed.
