Online casinos have provided a far greater range of casino games than has generally been the case in most land based casinos, but roulette still appears to be the online casino gambler’s favourite casino game. Roulette is of course very easy to play, but also theoretically gives the casino game gambler the best chance of winning because the house edge is low. The major online casino operators also now provide roulette gamblers with the opportunity to play roulette in the live casino mode, thereby removing one of the main criticisms of roulette online which is the strange behaviour of the ball resulting from the use of Random Number Generators. The main appeal of roulette however, remains the opportunity for the gambler to choose the degree of risk they wish to take. With 37 numbers on the wheel, including the zero, the roulette gambler can select up to 18 numbers with just one chip, by playing Red/Black or Odd/ Even, or they can take a variety of higher risk options from 12, 8, 4, 2 or even 1 number with just one chip. This option to choose the risk factor is what gives roulette its favoured ranking amongst casino games. Most roulette gamblers in land based and online casinos will commonly use a variety of these options for each spin of the wheel, perhaps going for a big pay out on a single number bet or a split whilst also effectively laying off some of the stake with a 2/1 bet on red/black for instance. Gamblers on roulette should of course always remember the Zero, which is where the house has the edge because Zero is neither red nor black, or odd or even. In American roulette there is also a Double Zero which increases the house edge, so would not be the casino game of choice for most Irish online casino gamblers.
