Online Roulette | Live Roulette and RNG Explained


The story of online roulette is a lengthy and fascinating one, taking place through several centuries, across the entire world. From France to Germany, to the US or even the Caribbean, this game has shaped gambling as we know it today, and has become ubiquitous in casinos of all kinds.

Roulette has come a long way since its invention in 18th century France, developing into multiple types. It has even become the subjects of legends. They say that one of its inventors, Francois Blanc, bargained with the devil in order to obtain the secrets of the roulette!

In reality, the game is as popular as it is easy to understand. The modern layout of roulette is designed with simplicity in mind, and with the advent of the internet and the introduction of the online variant of roulette, it has never been easier to grasp than it is today. As such, making a deal with the supernatural is hardly necessary to understand online roulette. We are more than confident that this guide will explain everything you need to know in order to enjoy it.

How does online roulette work?

Traditional and online roulette are not very different at all. Both games are based on placing bets on a single number, a group of numbers, a colour (red/black) or on an odd/even number. After placing a bet, the winning number is decided by spinning a wheel with a ball inside. The ball eventually stops on a number out of 37 (in European roulette) or out of 38 (in American roulette), deciding the winning number. The betting area layouts, along with the types of bets, are no different either. The fact that the game remains mostly the same is what made roulette on online casinos so popular and easy to access.

The most obvious difference, of course, is that instead of using a physical roulette, the result of a spin is not decided by what pocket the ball lands in, but rather by an RNG (random number generator). Using sophisticated algorithms, an online roulette software decides upon a random number for each spin. As such, the outcome of a spin is just as random as if a traditional roulette were used.

Another notable difference is the digital interface used for a layout, in the lack of an actual, physical betting area. This makes playing much more convenient, as players can easily keep track of their bets and the betting history, and can place bets a lot faster, up to even 65 bets per hour. Bets are placed by clicking the areas of choice on the betting table and dropping the virtual chips there. The computer quickly settles the outcome of a bet without mistake.

The live dealer roulette

As entertaining as the online roulette is, sometimes it simply cannot match the experience of using a traditional roulette; for some, having a computer generate some random numbers to decide their fortune is a bit too lifeless. Some may even have concerns whether the computer program is truly fair. Luckily, online casinos have found a way to reconcile the sentiment of a traditional roulette with the accessibility of a digital interface: the live dealer roulette.

While the game itself and the betting still take place virtually, through an online casino, the winning number is no longer decided through RNG. Instead, the player can view a live broadcast of the spin as they are playing, streaming from a specialized studio. The player will see the dealer spin the roulette in real time in order to decide the winning number after the bets are placed.

This brings the online roulette a bit closer to the live experience. Players can chat to other players and to the dealer as well. Since the players can see where the ball lands for themselves, it removes the possible feeling of suspicion over computer programs. This is why live dealer roulette has become very popular, with a large number of online casinos offering this option.

European Roulette

The European roulette was the first one to be invented and the most common one found in online casinos. Although there are plenty which offers both the European and the American variant. The European roulette wheel has 37 numbers, from 0 to 36. All numbers are coloured black or red, except for 0, which is green. That is the so-called house advantage.

This option is the most popular because, due to it only having one “0” pocket. This gives the house an advantage of merely 2.63%,  making it easier for players to earn more.

American Roulette

Unlike the European option, American roulette uses a wheel with 38 numbers; the previously mentioned numbers from 0 to 36, in addition to another pocket labelled “00”. Both the 0 and the 00 numbers are green, doubling the house advantage to 5.26%. This type of roulette is the more preferred one in the US, Canada, South America or the Caribbean. With the exception of this difference, though, both types of roulette are identical.

Other types of online roulette

The French roulette is almost identical to the European model. Even though it is a bit harder to find it online, it has the advantage of a particular type of insurance: if the ball lands on zero, only half the bet is lost. Furthermore, if the player bets on even/odd and the winning number is 0, the bet is retrieved if they win the next round.

Multi-wheel roulette is meant for more dynamic players; instead of one, up to 8 wheels can be used simultaneously. While there’s only one betting board, the results from all the wheels are taken into account. For example, if a player hits the same number on more wheels, the wins are much bigger.

Multi-ball roulette enables the player to use up to three balls in a single spin, resulting in more winning numbers. The bet is however divided by the number of balls in play.

An Ageless Game

All in all, the roulette has maintained its status as one of the most prestigious gambling games. Proven by its popularity and accessibility in the virtual medium and through online casinos.
