Roulette is a casino game based on the idea of the perpetual motion machine, studied and built by Blaise Pascal, a French mathematician, physicist, inventor and philosopher. In his quest for the hypothetical machine, Pascal is believed to have invented the roulette wheel, as his studies shared concepts and probabilities inherent to gambling. Accidental or not, Pascal’s invention was a roaring success — one that was quickly adapted to casino gameplay all across Europe. As the roulette table game took the world by storm, several distinguishing features emerged around the world, creating the three roulette wheels as we know them: the European, French and American wheels. Let’s take an in-depth look at the inner workings of the roulette, the numbers on a roulette wheel and other features that you may encounter when playing this incredible game.

The Roulette Wheel


The roulette wheel is designed with several indented pockets, each with its own number and respective colour. How many numbers on a roulette wheel will you encounter? There are two variations to the wheel. The European roulette wheel — single zero roulette — comes with 37 pockets on the wheel, numbered zero to 36 and has a 2.70% house edge. On the other hand, the American roulette wheel has 38 pockets, numbered zero to 36 plus the double zero pocket. Since there are more numbers on this wheel and thus more outcomes, the house advantage rises to 5.26%.

The Table Layout

The interior betting area has the individual numbers on the layout. The exterior betting area contains boxes for the columns Odd/Even and Red/Black, as well as the different groups of numbers that account for all Inside, Outside and Neighbour roulette bets. The inside numbers are arranged in twelve rows of three figures, creating three vertical columns. The ‘0’ and ‘00’ are placed above the columns. In Live Casino games, the layout will be presented horizontally to the perspective of the player; the Inside and Outside bets will be available on the central panel, and the Neighbour bets will be displayed in the rightmost section.

An Overview of Roulette Numbers

  • EUROPEAN ROULETTE – As noted before, the European wheel has 36 numbers and a single zero on it. The roulette wheel numbers are arranged in the following sequence: 0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3 and 26.
  • AMERICAN ROULETTE – The American wheel has 36 numbers too, as well as the zero and double zero. The roulette wheel numbers are arranged in the following sequence: 0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1, 00, 27, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14 and 2.

Whats is the difference between European, French and American Roulette Wheels?

Roulette is a French word meaning ‘little wheel’. This provides players with a clue as to the birthplace of the roulette table game, which is speculated to have originated back in 17th-century France. Although the history of roulette is not so clear cut, the gameplay certainly is. The objective of roulette is straightforward: players wager on the numbered pockets that they think the ball will land in. The live dealer will spin the wheel, and the winning number will be determined by the ball’s final resting slot. There is a variety of wagers that players can place, ranging from straight up, single-number bets to wagers that cover groups of numbers by row, column, colour, odd/even and other groupings. Since roulette has gained worldwide popularity over the years, some key differences emerged between European, French and American games. Let’s have a look!

LA PARTAGE — it comes from the French word ‘partager,’ which means ‘to share’, or ‘to split’. The rule stipulates that if you place Outside, ‘even money’ bets and miss because the ball falls on ‘0’, you will receive half of your wager back. When comparing the French and European roulette, the French version has more favourable odds for the player than the European one. This is because la partage lowers the house edge to 1.35% on even-money wagers.

EN PRISON — the rule is closely related to la partage and is translated to ‘in prison’ from French. In this case, if you made an Outside bet and lost since the ball lands on ‘0’, you have an option of either taking half your wager back (la partage) or locking the bet for the next spin. If you take the latter option, the croupier places a marker on your bet to signify that it is imprisoned (thus the ‘in prison’). The entirety of the bet will be paid out if the next spin is a win for the player; otherwise, the entire wager is lost. For example, a player wagers €10 on Even and the wheel lands on ‘0’. If you choose not to take advantage of la partage, then the live dealer will then place a marker next to the bet, and the wheel will be spun again. If the outcome of this following spin is an even number, then you will win your €10 back. If the outcome is an odd number, then the €10 will be lost. Note that many casinos with European tables do not use la partage or en prison, so make sure to view the rules of the game before wagering.



Inside bets consist of all the wagers placed inside the betting area, on the numbers or on the lines in between them. The following list includes all of the inside bets a that player can place:

By contrast, Outside bets consist of all bets placed outside of the betting area.

Apart from all these, players may also place Neighbour, Special, Complete and Favourite bets as well. These almost exclusively apply to Live Casino roulette tables.


On Live Casino roulette table games, all wagers are placed using the multi-coloured casino chips. These chips will be available during the betting window, which is often timed — pay attention to the pace of the gameplay if you don’t wish to skip a round!

  • EUROPEAN ROULETTE – The European roulette wheel features 18 red numbers and 18 black, for a total of 36 numbered pockets on top of the single zero pocket, which will be displayed in green. This classic roulette wheel and table layout provide straightforward and entertaining action. The relatively low house edge implies that you are likely to land wins reasonably often but keep in mind that roulette is a game of chance, so winning can never be guaranteed.
  • FRENCH ROULETTE- French roulette is played on a European wheel, and is only marginally different from other games of roulette, with the main difference being in the rules of play. This French roulette wheels feature the la partage and en prison rules.
  • AMERICAN ROULETTE – The big difference between the American roulette wheel and other versions is in the double zero. The American wheel has 38 roulette wheel numbers — the extra one being the ‘00’. It has a second green ‘00’ slot to accompany the ‘0’ pocket found on the European wheels, which slightly alters the table layout. The American version includes the same outside bet, and the gameplay is nearly identical. When it comes to comparing American and European roulette, the European wheels give the players better odds, as expressed by the lower house edge. Aside from the numbers on the roulette wheel and the increased house edge, there is no difference between American and European wheels.
