Brief History of Online Roulette

Back in the day, gambling enthusiasts had to dress up and commute to the closest land-based casino to them before placing bets on their favourite casino games, including the popular roulette game. 

However, the status quo changed with the arrival of the internet, which led to the advent of online casinos and online gambling.

Roulette Rules - How to Play!

The game features a large wheel designed with small pockets that contains a wide range of numbers, from 1 through 36. 

Each of these pockets features two distinct types of colours: red and black. In addition to this, there is also a 37th pocket that contains the number Zero (0) and a 38th pocket that features 00 (in the case of the American Roulette). Both of these pockets are usually green coloured.

The way the gameplay works is simple: the roulette wheel is spun, and a perfectly balanced small ball is thrown in the opposite direction of the wheel. 

The game's goal is for players to predict where the ball will stop as soon as the wheel stops spinning. 

You can usually bet on the ball stopping on a single number, a group of numbers, a particular colour, and a few other options. 

Wagers and Rules of Roulette

The players in the game place their chips on the table on either inside bets or outside bets; on the inner or outer side of the wheel. Inner bets mean that the player will place his/her chips on numbers or rows on the board next to the wheel. The bets you can make on the inner side are called inside bets and are the following.

WagerNumbers included
Straight upThe wager is placed on a single number.
Split betThe wager is placed on the line that separates two numbers. This way the bet is on two numbers.
Three Line / StreetChips are placed on the edge of a horizontal row. This includes three different numbers.
CornerThe wager is placed where the numbers meet in the corners. The bet is on four different numbers.
Six LineThe chips are placed on two adjacent streets or rows. The bet is here on six different numbers.

Apart from these wagers, some Roulette games have even more types of bets. However, the distribution of numbers marked on the board is always the same. 

WagerNumbers included
Column The chips are placed in the field marked with 2:1 at the end of each column. The bet includes 12 numbers.
1: 12, a:12 og 3:e 12The wager is placed on the first twelve numbers 1-12, second twelve numbers 13-24 or third twelve numbers 25-36.
High / LowThe wager is placed on either the high numbers 1-18 or the low numbers 19-36.
Red / BlackThe wager is placed on either the red or the black colour. It includes 18 numbers.
Odd / EvenThe wager is placed on the field with either odd or even numbers. It includes 18 numbers.

Variations of Online Roulette

The three main versions of the roulette game that you will find at most casinos are European Roulette, American Roulette, and French Roulette.

As you might have guessed, American Roulette is the version typically played at most American casinos. French Roulette is fancied by the French, while European Roulette is common across different casinos across Europe.

This section will look at some of the most popular roulette variants you will find online.

American Roulette

American roulette is one of the most popular roulette variations out there today. The main characteristic of the American roulette is the presence of the double zero (00) pocket alongside the standard single zero (0) pocket, adding an extra space on the roulette wheel and bringing the total pockets to 38.

Another remarkable thing about the American roulette is that regular numbers 1 through 36 are positioned differently between the two zero pockets on its wheel and table compared to other roulette types. 

However, this variant's bets, payouts, and rules are similar to the European version.

Sadly, the extra 00 pocket available on the American roulette wheel pushes the odds towards the casino and increases the house edge of the variant on single bets to 5.26%. 

European Roulette

European roulette is just as popular as American roulette, if not even more popular. Unlike the American version, the European roulette comes with the standard single zero (0) pocket on its wheel and table, making 37 pockets.

Due to the fewer pockets that the game's wheel has, the house edge is half that of the American version. 

The reduced house edge of 2.7% helps players to make significant gains in the long run, or at the very least mitigate their losses, making this version the go-to for most players.

French Roulette

Interestingly, many casino enthusiasts often confuse French roulette with being the same as European roulette.

This is because the wheel setup and the game's rules of French roulette are similar to European roulette. 

However, while French roulette mirrors the European version in many aspects, the game has two special rules that differentiate it from its European counterpart. 

The first rule is the ‘la partage’ rule, which allows players to get back half their wager should they lose an outside bet due to the roulette ball landing on the zero pocket. 

The second rule is the ‘en prison’ rule, which gives players the opportunity to recover all their stakes if they place an even money bet and the ball lands on the zero pocket. 

Multi-Wheel Roulette

One exciting aspect of this game is that a player doesn't have to use all the available wheels simultaneously. Instead, you can choose how many wheels you want to activate during any game round.

Although the multiple wheels may seem overwhelming, you should note that the Multi-Wheel roulette works the same as any roulette variant. 

This means that players still place bets on a single board, and the bet placed will be the same on all active wheels. 

Double Ball Roulette

The idea of this game was to take the roulette action to a whole new level and provide a little bit more excitement than the standard version of the roulette game.

As the variant's name implies, the game adds a second ball to the regular ball spinning on the roulette wheel.

Live Roulette

You will agree that the advent of online casinos brought a lot of benefits to roulette enthusiasts. One of the biggest benefits naturally is the high level of convenience which makes roulette games accessible to players from the comfort of their homes or just about anywhere with just a few clicks on their devices.

However, as exciting as it was to play roulette, it couldn't capture the excitement that casino enthusiasts usually get from physically playing the game in brick-and-mortar casinos. 

The story changed with the creation of live casinos, which brought about the availability of live roulette games. 

No longer do players have to play RNG-generated roulette games. Players can enjoy a realistic and exciting experience with a real-life dealer, and other players streamed live in HD with the live roulette games. 

It is also worth noting that the live roulette game also comes in various variants, like the standard roulette game. 

So, before joining a live table at your casino of choice, ensure that you join a table that features the variant you are more comfortable playing.

Demo Roulette Game

Demo roulette games are developed just like the regular ones. The only difference between demo roulette and real money roulette games is that the former doesn’t require real money bets. 

Instead, it incorporates the use of virtual credits, which are often inexhaustible. This gives players the chance to try out the roulette game and enjoy its gameplay without risking their funds.

Naturally, since the demo roulette game is digitized and does not involve actual cash, you cannot win real money playing the game. 

You can only win real money by playing the real money version of the roulette game.

Types of Roulette Bets

We will look at the different types of bets available to roulette enthusiasts when playing the game online. 

Generally, there are two major categories of roulette bets, namely "Inside Bets" and "Outside Bets."

Inside Bets

The inside bet is the roulette game's simplest and most common betting variation. Generally speaking, inside bets are the bets made on single numbers or a few numbers. 

The bets derive the name "Inside Bets" because they are placed inside the roulette table layout, where the numbers are listed.

Though it generally varies from bet to bet, when you place an inside bet, you attempt to predict what will happen from several possible outcomes, making it exciting and nerve-wracking.

Here is a brief rundown of the available inside bets.

  • Straight Bet (1 number): Straight bet refers to the type of bet where you place your wager on a single number. This means placing a bet on the roulette ball landing on any one of the red or black pockets or the 0 pocket or 00 pockets in the case of the American roulette. Naturally, if the ball lands on your chosen number, you win. You lose if it doesn’t. This bet usually pays out at odds of 35/1.

  • Split Bet (2 numbers): Split is the type of bet you place on any two separate numbers that are adjacent on the roulette board. You place the bet by placing your chips on the line between those two numbers. If the roulette ball falls in either number, the bet will payout 17/1.

  • Street Bet (3 numbers): Also commonly referred to as the "Trio Bet," Street bet is the type of bet that covers three consecutive numbers on the roulette table. You place the bet by placing your chips on the edge of the row containing the three numbers. For example, you can place a bet on the outcome of a spin landing on "16, 17, 18", "22, 23, 24", or "31, 32, 33". If any of the three numbers wins, the bet pays out 11/1.

  • Corner Bet (4 numbers): Commonly referred to as a "Square Bet," a Corner bet refers to the bet where you place your chips on the intersection between four numbers that makes a square on the roulette table. If any of the four numbers wins, the bet will payout 8/1.

  • Line Bet (6 Numbers): The Line Bet is also known as the "Six Numbers Bet," and it is similar to the Street/Trio bet. But instead of only covering one row of lines, it covers two consecutive rows of three numbers next to each other, making up six numbers. To make this bet, you need to place your chip on the intersecting point between the two rows on the outside line of the grid. The bet offers odds of 5/1.

Outside Bets

The second broad category of bets that Irish players can place when playing the roulette game is outside bets. This refers to the bets found on the perimeter of the table.

These bets are not placed on specific numbers. Instead, they revolve around a category of numbers and the colour and type of number.

One thing to note about outside bets is that it involves making predictions on very limited possible outcomes, two in some cases. 

As a result, the chances of winning outside bets are often higher than that of inside bets, a less risky and safer option for roulette enthusiasts. 

However, as the bet has a greater chance of winning, the payout is naturally smaller than you will get while placing inside bets. 

The outside bets available to players online include;

  • Red/Black Bet: This is the simplest and most popular bet type that you will find playing the roulette game online or offline. You place a bet on the roulette ball to land on a red or black number at odds of even money (i.e., 1/1). So, if a player wagers €100 on black, and the ball lands on a black pocket, the player wins the bet regardless of the number. But if the ball lands in a red pocket or the green zero (0) pocket, they lose.

  • Odds/Evens: This is also like the red/back bet. Except that in this case, players will be placing a bet on whether the winning number will be an odd number (1,3,5,7,…..) or an even number (2,4,6,8,…..). Like the red/black bet, the odds are also 1/1, making it an even-money bet. Here, the 0 or 00 pocket doesn’t count for either bet, so if it comes up, the house wins.

  • High/Low Bet (1-18/19-36): This involves placing a bet on the roulette ball to land on a low number (1-18) or a high number (19-36). Should a number within the range you select emerge as the winning number, the bet pays at odds of 1/1, making it an even-money bet.

  • Column Bet: Typically, there are three columns on a roulette betting board, with each column having 12 numbers and a section marked "2 to 1" at the end. The column bet covers all the numbers in the chosen column. This type of bet offers 2/1 odds, which means that if the ball lands on any number in your chosen column, you double your wager.

Payouts on Roulette Bets

One of the most vital things to note when playing roulette games online or offline is that the payout you will win during any roulette round depends on the type of bet you place. 

The lesser the numbers covered by a bet, the more the payout that you will get if the bet wins. Similarly, the more numbers your chosen bet covers, the lesser you will get in payouts. 

It is a simple concept that emphasizes the potential rewards as proportional to the risk incurred with each bet.

It is also worth noting that the size of payout that you will get when you play the roulette game depends on your actual bet size. Small wagers will bring small rewards, while bigger wagers will bring bigger payouts.

However, when you start playing, you need to do proper bankroll management and not get carried away looking for big paydays by carelessly placing huge bets.

The Most Popular Roulette Betting Systems & Strategies

This section of our guide on online roulette will look at some of the most popular strategies that you can apply to enjoy online roulette when you play. 

But, before we move on, we should mention that, like any other casino game, the roulette game also largely depends on luck. 

As a result, no roulette strategy will guarantee you 100% winnings. However, while they will not guarantee you winnings, many of the most common roulette betting systems and strategies will improve your winning chances.

The Martingale

The Martingale betting strategy is the most popular strategy you will come across when playing roulette games online or offline. 

The strategy plays off the idea that you must eventually win when you play the roulette game. 

The rule of the strategy demands that you double your bet after every loss, which means that when you eventually win a spin, you will recuperate the money you have lost plus a little profit. After this, you will then start again following the same pattern.

You should note that for this strategy to work, it is important to only place even money bets, such as odd/even, red/black, or 0-18/19-36.

Due to its simple nature, the Martingale strategy is the ideal starting point for players who are new to the game of roulette. 

However, the major problem with the strategy is that it can get expensive very fast, especially when you are on a losing streak, which can take a toll on your bankroll.

D’Alembert Betting System

The D'Alembert roulette betting strategy is similar to the Martingale system. It is based on bets placed on even-money areas of the table and encourages roulette players to increase their wagers each time they lose. 

However, unlike the Martingale system, the D’Alembert system does not eat into your bankroll quickly. 

Instead of doubling your wager after every losing stake, it demands that the player’s stake be increased by one unit. And for every winning spin, the stake will be decreased by one unit.

The Labouchere

Another popular betting system that you will find common amongst roulette enthusiasts online or offline is the Labouchere betting strategy. 

Like the other systems on our list, it works on even-money wagers. In this system, casino players decide on the amount they want to win in each session of the roulette game and change the bet size for each spin based on whether they are winning or losing at the time.

As for how the system works: a player will write down a sequence of positive numbers that sums up the predetermined amount they want to win. 

With each wager, a player will stake an amount equal to the sum of the first and last numbers of the sequence. If the bet is successful, you are to remove the two numbers, but if it loses, you are to append the sum to the end of the sequence. 

This will continue until all the numbers in the sequence have been crossed out, at which point, the player would have won the desired amount or until the player has run out of money.

  • The Fibonacci
  • The Paroli
  • Contra D’Alembert System

How Did We Find The Best Online Roulette Sites?

When it comes to playing the roulette game online, one of the vital things you need to note is your site choice. 

While there are hundreds upon hundreds of different online casinos offering real money online roulette games to their players, you cannot play at just any site for many reasons.

As such, before deciding on where you will play the online roulette game online, there are certain factors that you must consider, and our expert team has explained them below:

  • Licensing: Your choice of a casino must be appropriately licensed and regulated by the most reputable authorities in the iGaming industry, such as the Malta Gaming Authority (MGA), and the Gambling Commission of Great Britain (UKGC), and others.
  • Security: You must also ensure that your choice of casino takes safety and security seriously and provides all the appropriate and necessary security measures to create a safe and fair gaming environment.
  • Roulette Game Selection: As we have mentioned earlier, the roulette game comes in many different variants with unique attributes and features. So, you should only consider a site that provides as many roulette variants as possible, giving you multiple options to choose from when you want to enjoy the roulette game.
  • Payment methods: Different casino sites come with their selection of methods for processing deposit and withdrawal payments, with some sites featuring more options than others. So, before you sign up with a site, ensure that it features your preferred payment methods. That way, you will be able to process deposits and withdrawals comfortably.
  • Casino Bonuses: No matter the size of your bankroll, casino bonuses can be a great way to have more fun while playing the roulette game online. So, you should consider the available welcome bonuses and promotional offers that a site has to offer before signing up.


To sum up, online roulette is an excellent form of casino entertainment capable of offering players unending hours of fun. 

It is a great choice for Irish players seeking a fast-paced, entertaining activity. The game is straightforward without any complex or complicated rules, though it leaves room for some strategic thinking.

If you are a newbie, you should take some time to learn the basic set of rules that guides the game and utilize the demo version to get more familiar with the gameplay.

You should only try out the roulette game for real money after that. While you are having fun playing the game, remember to gamble responsibly.
