Roulette is a casino game, originating from the French, where it means “little wheel”. The roulette wheel is consists of 37 numbers from 0 to 36. The objective is for the player to wager on one or a combination of numbers. The croupier will spin the wheel and the payout the player in case the ball after spinning end up in one of the numbers, he has played.

The History of Roulette

The first historical proven roulette was manufactured in the 18th century in France. The game was played in since 1796 in the current form. The roulette wheel has been used in various casino in Paris since then.

Roulette wheels used in Paris in 18th century had both a zero and double zero, which were red and black. Since the early 19th century the color was changed to green to avoid confusing.

The single zero roulette wheel was invented by the frenchman François and Louis Blanc. He made the invention to compete with the traditional casinos, which offered the double zero wheel. Francois later moved to Monte Carlo, where the single zero roulette became the premium game.

Early edition of American roulette features the numbers from 1-28, 0, 00 and an eagle. The eagle was symbol of American liberty, but really just provided an extra edge for the house. Eventually the French double-zero roulette made its way up through America through the Mississippi, starting in New Orleans.

Today, the double zero wheel is dominant in the U.S., Canada, South America, and the Caribbean, whereas the single zero wheel is ruling everywhere else in the world.

Online roulette variations

As history tells, there is a reason, we have different versions of practically the same game. When we talk about online roulette today, then we work with the 3 following variations

  • European roulette
  • French roulette
  • American roulette

Please note, that some software providers may have invested their own style roulette, but this is typically only available at that specific provider.

European roulette

This roulette type is the most common online roulette form. The roulette is the single zero edition. It offers the best value to the player, which is probably why it is popular.

The wheel – European roulette

The wheel on the European version is well thought out to replicate randomness.

European roulette wheel

As you see, number on the European roulette shifts between red and black background color, except when the green zero is represented. The order in which the numbers should appear on a roulette wheel is fixed. Starting on zero and moving clockwise around the wheel, the order should be:


The order of the roulette wheel is not based on their arithmetic value. This specific order make the roulette game a very balanced game in theory. The order is designed to:

  • Confuse the gambler
    It is very hard for a gambler to take a look at the wheel and see any relation between the numbers and sectors. That is why it’s almost impossible to notice any bias, and bet on a specific sector as a result.
  • Red and black alternate constantly
  • Low (1-18) and High (19-36) are randomized
    On European roulette this is perfect, except for 5 and 10, which are neighbors. This is not done properly on an American roulette.
  • Even and Odd numbers are distributed evenly
    A maximum of 2 even or odd number are next to each other on the European roulette wheel..

As you see, the layout of the roulette wheel is not random, but some clever thoughts went into designed exactly how these should be placed.

The table – European roulette

When referring to the roulette table, we talk about where you place you bets for the upcoming spin with the ball. The design may vary between operators, but will in general look something like this.

This allows you to place 12 different types of bets, where 7 of these are within the category “inside bets” and the remaining 5 options are referred to as “outside bets”. In the next section we will walk you through all these options.

Advanced table layout – European roulette

Some casinos offer an advanced layout for the roulette table, which includes a representation of the actual roulette wheel. This additional addition will look something like this.

Announced bets

Wheel of announced bets

Voisins du Zéro – Neighbors of Zero

The betting option covers all the numbers on the wheel from 22 and until 25. This is a total of 17 numbers, which is 45,9% of all outcomes. This option is wide used to cover the section around the zero. Please notice that this option covers 9 numbers before the zero and only 7 after.

When clicking on the neighbors of zero, the roulette software should automatically place 7 chips down for you, which will exactly cover the numbers promised. Because this option is covered with individual coins, each winning option will not pay out the same amount.

Tiers du Cylindre – third of the wheel

Tiers du cylindre is a betting option covering 12 numbers opposite the zero. This is approximately a third of the wheel, covering from 27 to 33. This is 32,4% of the outcomes.

The option will place a total of 6 chips on splits to cover exactly the numbers promised. This means also that this bet pays 3 to 1, since we use 6 coins and will have a payout of 17 to 1 on any winning combination.

Red and Black splits

If the roulette software is offering red an black splits, then this will be split bets for either the red or the black numbers, which are not covered by Voisins du Zéro or Tiers du Cylindre. Red splits will cover this option with 4 chips, while the black splits could cover this with 5 chips, but sometimes uses 7 chips for extra payout on selected numbers 10, 11, 28 and 29.

French roulette

First of all, French roulette in online casinos is essentially identical to the European single zero roulette. Why this seems to be available some many places might have to do with the history of this game.

The wheel – French roulette

The wheel is identical to the European version, described earlier.

The table – French roulette

The table typically looks a bit different from the ones you seen in the European online versions of the game. Still there are many variations, but it would look sort of similar to the below image.

The wheel on the american version has 38 outcomes, the number from 1-36, 0 (zero) and 00 (double-zero)

American roulette wheel

As you can see the number sequence is different from the European version. Starting on zero and moving clockwise around the wheel, the order should be:


There are also some thought behind the design of the American wheel:

  • Numbers across from each other differ by exactly one.
  • The numbers alternate red and black, except when zero or double-zero comes between.

The table – American roulette

The table has a bit different look from the its European cousin.

Now we have both zero and double-zero at the top and in addition, black and red numbers are no longer creating a chess like pattern on the table.

Betting options – American roulette

You will find many of the same inside and outside betting options, which are previously described. This includes Straight up, Split, Street, Corner (Square), Six line (Double street), Dozens, Columns, Red/Black, Odd/Even, High/Low.

A basket here features 5 numbers, namely 0, 00, 1, 2, 3. This pays 6 to 1.

For the advanced options, the American version is not offering such.

Fun facts about roulette

There are many good stories about this game, and below we will tell a fewof these.

The Devils Wheel or Devils Game

There may be some psychology to this, with the addition of gambling being forced upon you by the devil. However, according to the legend, François Blanc got the secrets of roulette from the devil. This legend is based on the fact, that the sum of all numbers on the roulette wheel (0 to 36) equals 666, which is the “Number of the Beast“.

Lucky number 17

Number 17 is the most commonly played number on roulette world wide. It has probably something to do with the central position on the table, but might also be influenced by the fact, that this is the number James Bond plays.

Record color streak

The longest consecutive run of the same color on a roulette table is 36 times. This happened in a casino in Bristol, UK.

Make the right bet

Now you know about all the betting options on roulette, and you may be ready to test your luck at the table. You can either place your bets random between the options described, but you can also follow a specific roulette strategy, which will give you a pattern to bet from. Some of the popular strategies are Martingale or Fibonacci. These are both what would be called even odds strategies since they both work from a principle of covering around half of the number of the wheel for each spin. For more information, check our Roulette Strategy.

Table limits

When entering a table, you should also make yourself aware of the table limits. Limits are both for minimum and maximum stake, and will typically be different based on which type of bet you are making. In general, limits are higher on outside bet than inside bets. Since announced bets are variations of inside bets, then the limits from inside bets will apply here.

Online Live Roulette

Since 2007 online casinos started offering live roulette for their customers. The live roulette is basically a video feed from some studio, where a physical casino is set up. The wheel is then linked up to the software, from which the gambler placed his bets.

Through the software you can chat with the dealer, who will verbally respond to your queries. This can in general give you the feeling of visiting a land-based casino.

Some gambler only wager on the live roulette, since they believe that the software cannot be rigged. However with current regulation on software companies, it will probably be easier to rigged a physical roulette table than a software. But what they eyes see, the brain trusts.

A some live roulette tables, you will find higher limit that on your normal online game table.
