While you may be familiar with the workings of a traditional roulette wheel, things are a little different when it comes to understanding how roulette games work online. The main difference between land-based roulette playing and online roulette is the fact that the latter depends on something called a Random Number Generator (RNG) to produce its numbers.

This little device can be compared to a RNG chip that you are probably familiar with that is found in slot machines – both online and offline. Every second literally thousands of numbers are produced and these numbers are then extracted once the roulette wheel is spun. Using a set of rules that match the odds of the game, the numbers are mapped to an end result that finally produces the number/color that the roulette ball eventually lands on.

You might very well be hesitant to trust the RNG of roulette games on the internet, believing that they might be ‘fiddled’ with and thus change the odds of your winning. Bear in mind that most online casinos are businesses in every sense of the word and would be downright foolish to risk their reputations in an ever-competitive industry if they were caught fooling with the RNG. In my experience in the gambling world, I have found it very rare to come across sites that conduct unsavory playing practices such as ‘letting the player win’ in free mode in order to bait them onto their site, or the likes. Remember to check the message boards, gambling portals and blacklisted casinos to know which sites to avoid.

Remember that the odds differ between the two versions of roulette. American roulette has odds of about 5.3%, while European roulette is more worthwhile for you, the gambler, with a house edge of 2.7%.
