Roulette Terminology

Do you know your carr from your cheval? Do you know the difference between orphans and a colonne bet? Roulette is a game rich in terminology, with many of the game's distinctive terms stemming from its country of origin; la belle France.
Whether you're ready to put your roulette knowledge to the test, or want to sound like a pro at the casino, we've curated a helpful glossary of roulette terms, phrases and words to help you speak “roulette” fluently.

THE BASICS:

American Roulette

American and European roulette differ. In the US, Canada, Central and South America, the wheel has 38 pockets featuring numbers 1-36, 0 and 00 (known as double zero) and the order of the numbers is different.

Croupier

Also known as the dealer, the croupier is the staff member who conducts play at a casino roulette wheel.

Dolly

A small marker used in American casinos to mark the winning number until all winnings have been paid. Its name comes from the marker's “dolly-like” outline.

European Roulette

Across Europe and much of Asia, roulette wheels feature only one 0 alongside the numbers 1-36, giving European wheels a lower house edge compared to American roulette.

House Edge

The house edge is the advantage that a casino has over players at a roulette wheel, mathematically calculated as the percentage of each bet the establishment can expect to keep on average, over the long term. In European roulette the house edge is 2.70%, in American roulette the house edge is 5.26%.

Pockets

The uniquely numbered portions of the roulette wheel where the ball can land, numbered 1-36, 0 or 00.

BET TYPES

Carré
Also known as a corner bet or a quad bet, a carré bet is placed on four adjacent numbers inside the betting grid with a payout of 8:1.

Cheval
Also known as a split bet, a cheval bet is an inside bet placed on two adjacent numbers with a payout of 17:1.

Colonne
Also known as a column bet, a colonne bet is placed on one of the layout's three columns with a payout of 2:1.

Dozen Bet
There are three groups of 12 numbers players can bet on. A dozen bet is a bet placed on numbers 1-12, 13-24 or 25-36 with a payout of 2:1.

En Plein
Also known as a straight up bet, an en plein bet is placed on just one number on the roulette grid, with a payout of 35:1.

French Bet
A French bet is a popular type of bet seen in European casinos. To make a French bet, players place several bets which cover a particular segment of the roulette wheel.

Inside Bet
A bet placed anywhere on the numbers section (also known as the layout) of the roulette table.

Orphans
A bet commonly made in European casinos which covers three numbers; 6, 17 and 34, which are close together on the European roulette wheel but far apart on the layout.

Six Line
A bet placed on two neighbouring rows of numbers on the roulette layout, with a payout of 5:1.

ROULETTE RULES

En Prison
When an even money wager is made in European roulette and the “winning” number is 0, players may be able to take back half of their money or choose to leave their bet “en prison” (literally: in prison) for the next spin. If the next spin is also 0, their whole bet will be lost.

La Partage
When an even money wager is made on an outside bet (like Red/Black or Odd/Even) and the result is 0, some European casinos apply the la partage rule which means players do not get the option to spin again, but only lose half of their stake.
