Roulette Popular Games

As with any popular casino game, there are always a few variations which will keep the same basic rules but with a few tweaks here and there to keep you on your toes. Always read the specific game rules before you put down any hard cash.

European Roulette

Perhaps the most common roulette variant, the European game has 37 numbers on the wheel, from 1-36 plus a single zero. The rules are simple and the house edge is approximately 2.7% which makes it a popular choice for online gamers.

American Roulette

The only real difference between the European and the American roulette wheels is the American version has an additional digit, of ‘double zero’ which gives players more betting options, such as the ‘five numbers’ bet but it also increases the house edge.

French Roulette

While French roulette is considered to be the original version, it’s a little more complex to understand. However, crack it and you’ll be rewarded with the lowest house edge of any of the roulette games. The table layout is quite like the European version, and you’ll be able to enjoy all the standard roulette bets, but with a few more options.

As noted, online roulette is a game of chance, where luck determines who wins and who doesn’t. However, because online roulette offers players the chance to win up to 35 times their wager, it remains a popular choice. The odds of roulette actually depend on which variant is being played. A European Roulette wheel comprises 37 slots (36 numbers and a single zero), while an American Roulette wheel comprises 37 slots (36 numbers and two zeroes).

As such, even without going into too much detail about how the odds of roulette are calculated, it is plain to see that there is more chance of winning a game of European Roulette than it is American Roulette. The latter has a house edge of 5.26%, while simply removing one of the zeroes brings the house edge down to 2.7%. Playing European Roulette with En Prison rules and other unique rules can bring the house edge even lower.

Players win at online roulette depending on the type of bets they place on the roulette table. Some wagers have better payouts than others, however the chances of predicting them are naturally smaller.

Betting on a single number while playing either American or European Roulette will result in a 35 to 1 payout. The difference is, however, that the chances of getting this right will be 37 to 1 playing American Roulette, and 36 to 1 playing European Roulette.

A general rule of thumb is that players should avoid single number wagers and, only in the case of American Roulette, a five number bet, as these types of wagers have the biggest disparity between true odds and what you’re actually paid out.
To enjoy the best online roulette odds, players should choose bets that pay out 1 to 1 (even money bets), such as Even, Odd, High, Low, Red or Black bets.

game rules
Online Roulette Game Rules

Roulette is a particularly easy game to play, with very simple rules. It involves placing bets on a roulette table and spinning a wheel with numbered pockets to see where the ball lands. Correct bets result in payouts, according to where the betting chips are placed on the betting table, ranging from 1:1 and up to 35:1.

A roulette betting table is designed with numbers (excluding 0 or 00) arranged into 3 twelve-number columns. Surrounding these columns are different types of bets (eg. Even, Red, Odd) which players can wager on.

There are other, less common variations of the online roulette game that are available.

These include:
Players purchase chips and place their bets on the table. After the bets have been made, the croupier spins the roulette wheel and throws the ball in the opposite direction of the spinning wheel. The ball lands in the slot and the croupier announces the winning number. Payouts are then made according to the payout table and based on the wagers placed.

Online roulette game rules differ when it comes to American Roulette or European Roulette, and not only because an extra zero has been added. European Roulette usually also offers the option of the En Prison rule, which means that should a zero come up, players can surrender half their outside wager or, alternatively, leave them on the roulette table for the subsequent roulette wheel spin. This rule could actually bring the house edge down to just 1.35%.
Another rule is the La Partage rule which is similar to the former En Prison rule in that players stand to lose half their bet but cannot leave their wager ‘in prison’ for the next spin.

button information
Roulette Game Buttons Information

Online roulette games feature buttons which allow players to place their bets, spin the wheel and claim their winnings. While buttons will differ depending on the game variant played and the software casino provider used, it is safe to say that most online roulette games feature similar functions.

Playing Online Roulette for Real Money

Leading online casinos, such as the ones recommended by Ireland, offer players the opportunity to play quality online roulette from the comfort of their own homes. To do so, players need to open an account at the casino and follow a few simple steps. Whether players choose to download the software onto their computers or play instant online roulette using Flash technology, the steps to creating an account and playing online casino games for real money are simple.

While it is possible to create an account and play in practice mode only, in order to start winning at online roulette, players need to open a real money account. To do so, they first click ‘Play for Real Money’. The next step is to click ‘Create Account’. They are then led to a page where they are required to fill in a few important fields (eg. Name, contact information), before they are requested to read and agree to the terms and conditions. The final step is to click the ‘Create’ button and account will be set up.

Online casino sites’ customer support teams are on hand 24/7 to help players should they require assistance to create a real money account, as well as queries they may have about making a deposit into their account to fund their gaming sessions.

Free bets

The best thing about playing online roulette, rather than at a bricks and mortar casino, it that you can play for free, and even when you do play with real money you can still receive free spins.

Many online casinos will offer a few free no-deposit games, which you can play just for fun. Free online games are also a great way to get to grips with the rules and the buttons before you put down any cash.

The majority of online casinos like to entice new players with fabulous welcome bonuses or free spins on various games. Plus, when playing roulette you may also come across free bet bonuses, depending on the game and the casino.

Money Management

Like many games based on chance, you’ve got to be in it to win in, and the only way to stay ‘in it’ is to keep betting. Managing your bankroll allows you to play for longer and so increases your chance of winning.

Start with putting aside a little spare cash to build up to an amount you can easily replenish. Set yourself betting limits and stick to it. Being strict with yourself will minimise losses, while lots of small gains will keep your bankroll ticking over.

Roulette Payouts

As there are many bet types available in a game of roulette, each bet has a different payout. While inside bets are more precise but have larger payouts, while outside bets cover more numbers so the odds are greater but the payouts smaller.

For example, if you place a ‘straight up’ bet which is a bet on any number including zero, the payout on this inside bet will be 35 to 1. If you want to bet on the 1st dozen numbers (1-12), then your payout will be reduced to 2 to 1.

How to play like a professional

Roulette is largely based on luck, but if you know the rules inside and out, there are certain things to look out for to increase your winning chances.
First of all look for an online casino which offers a good payout percentage. If the game has a payout rate of 97%, then for every €100 wagered, €97 is paid out to the player and the casino gets €3.

Roulette Winning Strategies

There are many roulette strategies out there but be aware that these tend to be based on what is known as ‘gambler’s fallacy’ and have no basis in maths or probability. So, what can you do instead? First of all pick your game carefully. While American roulette is easier, the house edge is much higher than European or French.

To minimize the impact on your own pocket, take advantage of the various bonuses and promotions at online casinos. This ‘free money’ will help you bet with little risk to your bankroll, and any wins are the cherry on the cake.

Interesting Facts

Online roulette is one of the most popular internet casino games around, but here are a few facts about the game that you may not have been aware of.

The name ‘roulette’ is French for ‘little wheel’. It has also be referred to as ‘the devil’s game’. If you add up all the numbers on a standard roulette wheel, the total comes to ‘666’.

The most popular number to be played is 17, possibly due to its central location. 17 is also the favourite number of the fictional character, James Bond.

While the origins of the game are generally considered to be 17th Century French, it may have been based on an English game, ‘Roly Poly’, but no one knows for sure.


In 2010, Englishman, Ashley Revell, sold all he had and travelled to Vegas to put it all ‘on red’. His gamble paid off, the wheel spun and the ball landed on Red 7. He turned his $135,300 bet into $270,600.
