Once upon a time, a French inventor tried to create a perpetual motion machine. While he didn’t succeed in that, he did invent something that has been spinning every since – the roulette wheel.

Today, roulette is played in casinos all over the world. A ball is spun inside a horizontal wheel which is also spinning (in the opposite direction of the ball). Friction will gradually make the ball lose speed, and eventually the ball will settle in one of the numbered slots located around the edge of the wheel – thereby determining the winning number of that round.

The three main roulette variants is the French roulette, the European roulette and the American roulette. The French and European versions use the numbers 0-36. The American version have added an additional possibility by not just having a zero but a double-zero (00) as well.

If you play roulette in online casinos, you might find more novel roulette games in addition to the three staples.

If many different players around the roulette just put normal casino chips on the table, it could quickly create a confusing situation where it would be difficult to know who is the rightful owner of each bet. Because of this, the croupier can ask you to exchange your casino chips for special roulette markers. The croupier have access to roulette markers with various color combinations and can assign each specific color combination to a specific player, thus lowering the risk of confusion at the table.

When you don’t want to play at this table anymore, you simply tell the croupier and she will give you ordinary casino chips in exchange for your roulette markers.

These bets are found in the centre (inside) of the roulette table’s betting area.

Inside bets are suitable when you are willing to take a big risk. The chance of winning is low, but *if* you win – you get paid well.

Here are some examples of inside bets:

Name of the bet | Chip placement | Info |

Straight (also known as Single) | Fully inside the square of the selected number, not touching any of the lines. | A bet on a single number. You win of the ball ends up on this specific number. |

Split | Across the line shared by the two selected numbers. | Your bet will be spread over two numbers. You win if the ball settles on either of the two numbers. You can only select numbers that are adjacent to each other on the roulette table (their squares must share a line). |

Street | On the outer line of the selected street. | There are twelve streets on the roulette table, each street consisting of three numbers. The first street is comprised of 1-2-3, second street of 4-5-6, and so on. Select one of the streets and bet on it, and your wager will be spread over the three numbers included in that street. You win of the ball settles on any of the three numbers included in the selected street. |

Tiers du Cylindre | Tiers du Cylindre = A Third of the Wheel This is a bet on the twelve numbers that are the farthest away from the zero at the roulette wheel: 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33. |

Orphelins | Orphelins = Orphans This is a bet on the eight numbers that are neither Voisins du Zero nor Tiers du Cylindre: 1, 6, 9, 14, 17, 20, 31, 34 |

Finales en Plein | This is a bet on the numbers that end with a specific number (of your choice). Example: Finales en Plein Deux (deux = two) is a bet divided over the four numbers 2, 12, 22, 32. |

This is how the numbers are placed at the French and European roulette wheels (clockwise): 0-32-15-19-4-21-2-25-17-34-6-27-13-36-11-30-8-23-10-5-24-16-33-1-20-14-31-9-22-18-29-7-28-12-35-3-26

Number 1-10 and 19-28 are red if odd and black if even. For 11-18 and 29-36 the opposite applies, meaning that red numbers are even and black numbers are odd. The zero (0) is green.

On a traditional French roulette table, the numbers are only red and black on the wheel, not on the table. As a player, you are expected to know which numbers that are red and which numbers that are black without the table telling you.

This is how the numbers are placed at the American roulette wheel (clockwise): 0-28-9-26-30-11-7-20-32-17-5-22-34-15-3-24-36-13-1-00-27-10-25-29-12-8-19-31-18-6-21-33-16-4-23-35-14-2

Number 1-10 and 19-28 are red if odd and black if even. For 11-18 and 29-36 the opposite applies, meaning that red numbers are even and black numbers are odd.

The zero (0) and the double-zero (00) are both green.

*E**n Prison* and *La Partage* are two features that makes even-odds bet a bit more interesting, since they give you a chance to not lose your entire bet on even-odds (red/black/even/odd/high/low) when the ball settles on green.

It is fairly common for French roulette tables to employ the La Partage rule, while En Prison is associated with European roulette tables. Always ask before you start playing; never assume that La Partage or En Prison will be available. American roulette tables hardly ever offer La Partage nor En Prison, but there are exceptions – including a few well-known Las Vegas establishment such as MGM Grand, Wynn, Bellagio and Mirage – where you can find American roulette with La Partage or En Prison.

- You make an even-odds bet and the ball drops on 0.
- The croupier offers you to let your bet be imprisoned (“en prison”) instead of you losing it.
- You agree and the croupier places a special marker on top of your bet.
- If your bet wins the next round, you get the wager back. If your bet loses the next round, you lose your wager.

So, what happens if the ball drops on 0 again? That depends on the rules of the house. It’s a good idea to check in advance before you start playing.

- You make an even-odds bet and the ball drops on 0.
- You only lose half of your bet; the other half is given back to you.

In the olden days, the standard European roulette set-up would have the wheel in the centre of the table. In the United States, a set up with the wheel placed at one end of the table was much more common. Today, more and more casinos world wide – including casinos in Europe – have adopted the U.S. style, even for European and French roulette. One of the places that still keep with the old tradition is Monte Carlo, where the French roulette tables still have the wheel in the centre of the table.

Traditionally, French roulette tables have a red table cloth while European and American roulette tables have green table cloths.

Since the American roulette wheel have both a zero (0) and a double-zero (00), it gives the house a higher statistical advantage than the European and French roulette wheels. With a French or European wheel, the statistical advantage is 2.7%. With an American wheel, it is 5.5%.

Please note that the rules La Partage and En Prison will have an impact lower the casino’s statistical advantage. American roulette tables hardly ever employ these rules. La Partage is fairly common at French roulette, while En Prison is chiefly associated with the European roulette.
