So, What’s Roulette All About?

Roulette is a highly popular casino game. Its name comes from the French word for ‘little wheel’. The game itself is fairly simple, where the dealer or croupier spins the roulette wheel in one direction while throwing a little white ball in the opposite direction, where it will eventually land in one of the numbered pockets along the edge of the wheel.

While the gameplay is simple, there are many different terms that are used during the game, which may be confusing to new players. You’ll hear these terms while at the roulette table and also if you’re reading up about it online. This roulette glossary will simplify things for you in no time. 

Your Roulette A – Z

American Roulette

This version of roulette is mostly played in North, Central and South America. With this version of the game, there are 38 pockets which are numbered from 1 to 36, with a single and a double zero.


The edge of the roulette wheel, where the ball is spun.

Bet On The Layout

When a bet is placed on any of the numbers on the wheel.

Biased Numbers

Some numbers may hit more often than others and are known as biased numbers.

Black Bet

When you place a bet that the next winning number will be black.


Also known as a Corner Bet or Square Bet, this French term refers to a type of bet where the player puts the chip at the point where four numbers meet on the table (the corners) and so bets on all four of them with a single chip.


A player who copies the betting strategy of their neighbour.

Check Rack

This is the tray where the casino chips are kept.

Cheval Bet

The French term for a Split Bet – an Inside Bet on two numbers.

Column Bet

Placing a bet on one of the three available columns, with each one consisting of twelve numbers each, paying out 2:1

Combination Bet

A bet or wager that that has one or more chips on two or more numbers.

Corner Bet

A single bet placed within the inner four corners connecting four numbers.


Otherwise known as the dealer, the croupier will be available at all times during a game of live roulette, spinning the wheel, releasing the ball, calling out the bets and answering any questions you might have.

Dozen Bet

A bet on any of the three groups of 12 numbers on the roulette table: 1 – 12, 13 – 24 or 25 – 36.

Double Zero Roulette

Another term for American Roulette, the game with a single zero and double zero on the wheel.

En Prison

This French term translates to “in prison”, and is a rule which applies to even-money wagers only. When the ball lands on zero, a number of online casinos will allow players to either take half of the bet back or leave it “in prison” for another spin. If the ball lands on the zero again, the whole bet will be lost.

European Roulette

This type of roulette is mostly popular in UK casinos, continental Europe, and Asia. In comparison to the American version, European roulette only uses one zero on the wheel and this automatically lowers the house edge.

Even Money

Any bet that pays out 1:1, such as a bet on Red/Black or Odd/Even.

Inside Bet

This is any bet that is placed on numbers in the central area of the table layout. Players can make inside bets on individual numbers or entire groups of them. Inside Bets have lower odds of hitting, but pay out more when they do.

Line Bet

A bet on two adjacent lines of three numbers.


A bet on the neighbouring numbers 6, 34 and 17.


Not to be confused with Orphans! Orphelins is a bet on a neighbouring group of numbers.

Outside Bet

This is a bet placed outside of the table layout, covering a larger section of the roulette wheel. Examples are bets on Odd/Even or Red/Black.


When a bet is doubled after a win.

Red Bet

This refers to an outside bet which pays 2:1 when the player bets that the ball will land on a red pocket.

Split Bet

A bet which covers two adjacent rows of numbers.

Straight Up Bet

This is a bet which is made on a single number and players can bet by placing their chips on that particular number on the layout. This pays out at 35:1.  

Street Bet

A bet made on any row of three numbers, by placing a chip at the end of that row.

Voisins Du Zero

A French term to describe a bet placed on the neighbours of zero on the roulette wheel.
