There are two types of roulette, American roulette and European roulette. The difference between the two types is the number of 0's on the wheel. American roulette wheels have two "0's", zero and double-zero, which increases the house advantage to 5.4%. In European roulette there is only one zero, giving the house an advantage of 2.7%.

The two versions use chips differently also. American roulette uses so-called "non-value" chips, meaning that all chips belonging to the same player are of the same value determined at the time of the purchase, and the player cashes in the chips at the roulette table. European roulette uses standard casino chips of differing values as bets, which can make the game more confusing for both the croupier and the players.

Online casinos have continued to develop in sophistication, with new games being introduced every other month. However, some of the classics have proven to translate seamlessly to the virtual world of online casinos, and none more so than Roulette. As with most great ideas, the simplicity of the basic game is what makes roulette so attractive in both bricks and mortar and online casinos. We’ve all seen the iconic spinning wheel of the roulette table, and watched the declining spin of the little white ball in films and on television. However, when it comes to actually playing the game and placing a bet, things can start to seem a little more complicated. Here is a beginner’s guide to the different bets it is possible to place on roulette so that you can play with confidence, whether at online casinos or at your local bricks and mortar.
 

The first form of roulette was first devised in 17th century France, by the mathematician Blaise Pascal, who was supposedly inspired by his fascination with perpetual-motion devices. In 1842, fellow Frenchmen Francois and Louis Blanc added the "0" to the roulette wheel in order to increase house odds. Roulette was brought into the U.S. in the early 1800s, and again in order to increase house odds a second zero, "00", was introduced - although in some forms of early American roulette the double-zero was replaced by an American Eagle. In the 1800s, roulette spread all over both Europe and the U.S., becoming one of the most famous and most popular casino games.

Roulette is a casino and gambling game (Roulette is a French word meaning "small wheel"). A croupier turns a round roulette wheel which has 37 or 38 separately numbered pockets in which a ball must land. The main pockets are numbered from 1 to 36 and alternate between red and black, with number 1 being red. There is also a green pocket numbered 0. In most roulette wheels in the United States but not in Europe, there is a second zero compartment marked 00, also colored green.

Online casinos can for certain games offer better odds than land casinos on slots and other formats where the chance of winning is determined by the house. Table games like blackjack have an established house edge; for a given set of rules, they offer the same payout, online or offline. Reliability and trust are hard to establish. To solve this issue, many online casinos purchase their software from well-known companies such as Wager Works, Microgaming, Playtech and Cryptologic, though a little research into credentials of any e-commerce site you plan to use is common sense. These software companies use a random number generator to ensure that the numbers, cards or dice appear randomly. All reputable companies operating in a regulated environment use robust random number generators.
