The game of Roulette is one of the easiest casino gambling games to play, and consequently one of the most popular. Roulette is available on all the online casino sites and is generally played to the same rules, although gamblers should be aware that some American versions of roulette include two house pockets on the wheel, namely ‘ zero ‘ and ‘ double zero ‘. If the ball comes to rest in one of the house pockets at the end of a spin, all multiple bets on colour, odd/even, Hi/Lo, and columns for example will lose, and therefore the presence of two house pockets decreases your chances of winning. Most European sites offer roulette with just one house pocket ie. ‘zero’, which improves the gambling odds for the player. The objective of gambling on roulette is to predict which of the 36 numbered pockets on the roulette wheel the ball will come to rest in. You can gamble on individual numbers, which pay the highest return at 35 to 1, or more conservatively on a range of groups of numbers, from pairs, paying 17 to 1, to any one of a group of eighteen numbers, paying 1 to 1. The pay-out varies according to the odds of a winning gamble, but roulette is the casino gambling game which gives the player the best odds of winning, with the house ‘edge‘ at its lowest. Players can place any number of bets on each spin of the wheel, although each individual bet must be within the house limit. The more careful players will confine their gambling to the larger groups of numbers, gambling say on Red or Black, or 1 to 18 and 19 to 36, each of which pays even money for a win. These bets can of course be combined with gambling on any of the higher risk combinations, from groups of twelve, six, four, three or two, and one or more individual numbers. Almost all on line casinos offer the chance for players new to the game of roulette to play for free so that they can get to know how roulette works before gambling with real money.
