Origins and History of Roulette

Roulette HistorySeveral centuries, even millennia old, roulette is one of the oldest games of money and chance offered in casinos today. Its origins are not clearly established and there are many theories on the subject.

One of the most popular theories states that the origins of the game go back to the Middle Ages, when an ancient version was created by a Dominican monk. A second theory also suggests that monks may have been inspired by an old Chinese game brought back from a trip to Tibet. Another theory is that Roman soldiers laid the foundations for roulette by using a dismantled tank wheel to create a popular game of chance between martial campaigns.

But all these theories are still very difficult to verify. However, historians and other specialists in the field agree on one major fact: modern roulette as we know it today would be the work of Blaise Pascal. The mathematician and philosopher is said to have developed the first modern version of the game by drawing inspiration from various existing games (Biribi, Hoca, Even and Odd and Roly-Poly), as well as from perpetual motion devices.

The first written evidence of the presence of the game dates back to the early 18th century. It is at this time that the name roulette would have been used for the first time to designate the game. It was in 1716, at the Soissons Hotel in Paris. At that time, the game consisted of 38 numbers: the digits 1 to 36, a red zero and a blue zero. It was played in this way for a few decades in gambling establishments, notably at the Palais-Royal in Paris.

Then in 1842, the game knows a major evolution when the White brothers (Louis and François) decide to remove one of the zero squares of the game. The objective is to correct the too big advantage held until then by the casinos over the players. This major change led to the creation of the first European roulette tables. But at the time, the games had been banned in France since 1836. The White Brothers moved to Bad Homburg, Germany, where they set up their casino and roulette tables. It was a huge success and the biggest fortunes of the Old Continent flocked there.

In 1860, Charles III, Prince of Monaco decided to allow gambling on the Rock and entrusted the management of the Monte Carlo Casino to the White Brothers. Under their impetus and thanks to the roulette tables, the Monegasque city became the new “place to be” for gambling enthusiasts from all over Europe.

A few years later, the game travels to America with the boats of European migrants. It quickly became popular, especially in the west of the country. However, the American gambling establishments, less scrupulous than their European counterparts, decided to add another square to the game: the double zero. This new variant, which significantly increases the house advantage, is now known as American Roulette.

In the course of the 20th century, gambling became a fixture in casinos all over the world, from Las Vegas to Sydney, Monaco and London. Roulette became the “queen of casinos” and new variations were created.

Then, at the end of the 1990s, the first virtual casinos appeared. The online roulette tables are obviously present there thanks to the know-how of various publishers who propose first, versions with a Random Number Generator, then roulette tables animated by real live dealers.

The rules of roulette

Online roulette rulesRoulette is a game with very simple rules. It is played with a small ball that is thrown onto a circular cylinder with 37 (European roulette) or 38 (American roulette) spaces, each marked with a unique number. For the player, the goal is simply to predict which of these numbers the ball will land on each time.

To get a clear idea of what roulette tables look like, keep in mind that all roulette tables are made up of two main components: a cylinder and a play mat. Also known as a roulette wheel, the cylinder has the squares numbered from 1 to 36, coloured alternately red and black. In addition to these 36 squares, there is a 0 square coloured green. On a European roulette table, a 00 square is added to the cylinder. As for the gaming mat, this is the part of the table dedicated to receiving the players’ bets.

The roulette mat

As in other table games, the carpet is the part on which the roulette bets are placed. But in this game, its role is even more important and knowing it well, as well as its layout is essential if you intend to implement game strategies and win more. In concrete terms, the roulette mat contains all the squares on the cylinder, organized in such a way as to allow for different betting patterns. The roulette mat has several columns and rows, as well as spaces for specific bets.

The configuration of the roulette mat depends on the roulette variant you are playing. For example, on a European roulette table, the roulette mat has :

  • 3 columns of 12 numbers, each number being associated with a colour ;
  • a 0 located in a semicircle at the top of the mat, and colored green;
  • On either side of the columns, the areas dedicated to the following bets: Even, Odd, Black, Red, 1 to 18 (Miss) and 19 to 36 (Pass);
  • At the bottom of the columns are the spaces provided to accommodate bets on the first dozen (12P), second dozen (12M) or third dozen (12D).

Here, chips can be placed on or between the boxes depending on the type of bet you wish to make.

European online roulette

On an American roulette mat, an additional semi-circle appears at the top of the mat and welcomes the 00. The other betting areas are present, but with a slightly different layout from the European roulette mat.

American online roulette

Finally, on an English roulette wheel, the carpet is a slightly hybrid version of the two previous ones. The general layout is the same as on an American roulette wheel, but with a single 0 square. It should be noted that the latter cannot accommodate any bets.

Roulette bets

online roulette betsContrary to what many players think, betting your money on a single number is not the only way to bet at roulette. Many other types of bets are allowed. In fact, there are a lot of possible combinations. Here are the main ones, and the benefits they bring if you win:

  • bets on a full number: here you place your chips on a single number. If you win, you win 35 times the amount of your bet;
  • straddling: here your chips are placed between two adjacent numbers on the mat. If either of these numbers wins, you win 17 times your bet;
  • cross bet: to make this bet, you must place your chips on a cluster of three adjacent numbers. If one of them goes out, you win 11 times your bet;
  • betting on a square: you will have understood it, it is a question here of betting on a set of 4 numbers forming a square on the carpet. The payout for winning here is 8 times your bet.
  • bet on a sixain: the sixain is a bet made simultaneously on 6 numbers. It pays 5 times your wager if you win;
  • bet on 12 simultaneous numbers: here you bet on a dozen or a column. If one of the numbers covered by your bet is a winner, you cash out twice your bet;
  • simple odds: In roulette, simple odds are bets that take into account 18 numbers simultaneously. These include bets on the following sections: Red, Black, Even, Odd, Pass, Miss. If you win, the payout is one time the amount of your bet;
  • betting on 24 numbers: you also have the possibility to bet on 24 numbers at once. These can be numbers from two adjacent columns, the first 24 numbers (1 to 24), or the last 24 (13 to 36). The payout for winning here is half of your bet;

The case of zero at roulette

In roulette, the zero is generally considered “the casino square” because it offers a home advantage over the players. When the ball stops on this square, there are 4 main scenarios:

  • you have bet on multiple odds (bet on a full, straddle, cross, square, sixain or dozen). In this case, whichever variant you play, you lose your entire bet;
  • you bet on the simple odds at an English roulette table. You lose half your bet;
  • you bet on the simple odds at a roulette table. Your bet is “imprisoned.” The ball is re-raised and the result of this new round is decisive: if you win, you simply get your original bet back. If you don’t, it is permanently lost;
  • you bet on the odds at an American roulette table: your bet is simply lost. Same if the ball lands on the 00.

Example of a roulette game

Whether it’s in an online casino or in a live casino, roulette games are played in much the same way. It all starts with the bets, the beginning of which is announced by the dealer (or the computer system as the case may be) with the phrase: “Make your bets”. You must then place your bets on the roulette mat. When the dealer announces “All bets are placed. Nothing goes right anymore”, the betting phase ends and no more bets are taken into account.

The dealer throws the cylinder clockwise, then places the ball and throws it counterclockwise. Once the ball is stopped on one of the squares of the cylinder, the winning number is announced. If that number is one of the numbers you bet on, you are a winner and receive the payout for your bet. Otherwise, you simply lose your bet. Once the payouts are made, a new game is started.

Top 5 Strategies for Winning at Online Roulette

Roulette is first and foremost a game of chance. Unless you cheat by tampering with the system, it is therefore impossible to influence the outcome of a game. This is a fact that you have to integrate and accept. However, there are a number of strategies that, when properly applied, can help you optimize your gambling sessions. These are the following betting strategies:

Les Martingales

The Martingale is undoubtedly the most common betting strategy in roulette. Chances are you’ve at least heard of it. In practice, it is a strategy that relies on a process of covering losses with a large winning bet. In practice, there are several variations of this strategy. For example, to implement a classic martingale, you have to double your bet each time after a losing bet. In order to avoid too big losses, it is generally recommended to use it with simple odds bets.

For example, you can start by betting €10 on the Reds. If after the first round you win, then you have to bet the same amount again, but this time on Black. If, on the other hand, you lose, you will have to double your bet on the same choice; i.e. you have to bet €20 again on Red.

La Martingale can be profitable in the long term. However, it requires a substantial budget and the ability to apply it strictly and with composure.

Paroli’s method

While the Martingale recommends doubling your winnings every time you lose, Paroli’s method instead suggests increasing your bets by one each time you complete a winning round. The goal here is to maximize your winnings quickly, without necessarily spending too much time at the table.

Labouchère’s method

This is a betting strategy based on a sequence of numbers and only applies to simple odds. Basically, the betting mechanism is as follows:

  • select a sequence of numbers, for example 1-2-3-4-5-6-7 ;
  • start by betting the amount resulting from the sum of the numbers at the extremes of the sequence, i.e. 1 7 = €8;
  • if you win, cross out those two numbers and go back to the same mechanism;
  • if, however, your bet loses, you must add the amount originally bet next and repeat the same calculation to determine the amount of your bet for the next round. Here, the new straight will then be 1-2-3-4-5-6-7-8, so you will have to bet 1 8 = €9 on the next round.

Such a betting strategy does not allow you to make big winnings in one go, but it does provide the player with profits fairly quickly.

The Fibonacci Method

This is an even more complex betting strategy. Here, the sequence of numbers you need to consider is made up of numbers, each of which is the sum of the previous two. For example: 3-5-8-13-21-34-55-89-144-233… The application is as follows:

  • bet an amount equal to the first number on the list;
  • if you win, bet the sum of the previous two numbers on the list and cross them off;
  • if you lose, bet the amount of the next number on the list.

The objective of this strategy is to quickly accumulate twice as many gains as losses in a few games. But be careful not to blow your budget.

The d’Alembert method

D’Alembert’s method is often presented as a less dangerous version of the classical Martingale. This system recommends you not to double your bet in case of loss, but to add one unit on the next bet in case of loss and to withdraw one in case of gain. The objective of this strategy is to multiply small wins and limit large losses for a positive end result.

The James Bond strategy

Ian Fleming, the writer behind the James Bond series, was a gambling enthusiast. His character is therefore often staged, playing baccarat, but also roulette. In one of his books, the author gives details of a betting strategy that he considers unstoppable. It is carried out with a minimum amount of 200 €, which is distributed as follows over one round:

  • 140 € on the last 18 issues (19-36) ;
  • 50 € on numbers from 13 to 18 ;
  • 10 € on the 0.

By using this strategy, you can guarantee yourself a win almost every time, unless the winning number is between 1 and 12, which clearly won’t happen as often as it might otherwise.

It should be noted that most online casinos prohibit players from using these different strategies, under penalty of cancellation of winnings and closure of your account for the most severe. If you still intend to use them, you will have to do it in a subtle way and especially without abusing them.

5 tips to put all the chances on your side

Like all games, roulette has its little secrets that regular and passionate players alike know. We share them with you here, so that you can maximize your chances in your next online roulette game.

Tip 1: Choose the right variant

Depending on the roulette variant you are playing, the casino’s statistical advantage is not the same. To be more precise, you should know that American Roulette, with its two zero squares, offers a greater home advantage (5.4%) than European Roulette (2.76%). Therefore, whenever possible, you should use the latter option during your online gaming sessions.

Tip #2: Limit the risks

If you really want to improve your chances of winning at roulette, it’s important not to fall into the trap of multiplying your bets on a full number. While it’s true that you can make a lot of money with this bet, you should also be aware that the probability of winning is extremely low. The odds are only about 1/37 or 1/38, depending on the variant. Therefore, avoid trying this “poker move” over and over again, and instead focus on bets on simple odds and other bets with a higher statistical probability.

Tip 3: Vary your game strategies

You do not have to choose among the different betting strategies presented above. In fact, the ideal is rather to use as many as you wish, making sure you understand and apply them well, of course. Vary the strategies and get the most out of each one.

Tip 4: Set a budget and stick to it!

Whatever strategy you use, keep in mind that roulette is a game of chance. You must therefore be aware that you can lose. To avoid getting into debt, therefore, set a capital amount that you are willing to lose from the outset. When this limit is reached, accept the fact that luck was not on your side and come back to play another time. In any case, don’t fall into the classic trap of wanting to cover your losses. The bill may be even saltier.

Tip 5: Cash out your winnings

Just as it is important to set a maximum loss limit, it is also important to set a winning level at which you must cash out your winnings and stop playing. Many gamblers go by feel, trying to “feel” when their luck turns. But the ideal is probably to set firm limits and stick to them so that you don’t lose everything again.

Roulette variants

At online casinos, there are many different types of roulette. But they are almost all derived from the following main variants:

European Roulette

It is the most common, but also the most advantageous of the roulette variants. It has a single 0 box. All the rules specific to this variant have been developed in the previous paragraphs.

English roulette

It is, as its name suggests, a variant originating from across the Channel. Like European roulette, it has only one 0 box. However, it has a few special features. Bets on 0 are not allowed. The layout of the roulette wheel is also slightly different from that of European roulette. In this variant, each player receives chips of a specific colour. For the rest, the rules are almost identical.

American Roulette

The main feature of this variant is the presence of an additional 00 box which increases the advantage of the house. The game board is also arranged differently. But the rules are the same as those of a European roulette wheel, except when the ball stops on a 0 square, as explained above.

In addition to these variants, there are also others, somewhat less common, but just as interesting. These include Mexican roulette and German roulette, among others.
