like Dolly

A marker used to denote the winning number on the table. It got the name because the first versions of the marker resembled a doll. Dolly helps the players and the dealer to keep track of the winning number and make sure all winning bets are paid accordingly.
Double Zero:
Exists only on the American wheel. The space marked with two Zeroes (00). When this field exists, the wheel is often referred to as a “double zero” wheel.

A wager placed on one of the three number dozens available. This is an outside bet, paying 2 to 1.

like En Plein

En Plein (Plein): The French term for the straight up bet, i.e. the bet placed on an exact number. En Plein pays 35 to 1 on the European and 36 to 1 on American roulette.
En Prison:
A special rule applied in some casinos where a player playing a bet which pays even money can get a half of his wager back or let it ride for another spin. The rule is only applied when the ball lands in Zero. If the player leaves his or her bet and the ball lands in Zero again, the bet is lost. To see what online casinos offer this and other special rules, check out our Online Casino Comparison page.

like Fibonacci

A betting system based on mathematical progression but a bit more conservative than wildly popular Martingale.
The machine used by croupiers to separate different colored chips after collecting them from the felt. All players at the table are given chips of different color so there is no confusion about who placed what bets, and it is very important to be able to separate these chips quickly and always have them ready for players.
Five number bet:
Used only on American roulette. This is the bet covering five numbers: Zero (0), Double Zero (00), 1, 2, and 3.

like High/low Bet

High/low bet:
An outside bet which pays even money. The player either bets low numbers (0 to 18) or high numbers (19 to 36).

like Inside bet

Inside bet:
A bet placed on the inside of the felt, i.e. any bet placed on the numbers.

like La partage

La partage:
Another special rule available in certain casinos. La partage is similar to En Prison rule, as player gets back half of an even money bet if the ball lands in Zero. However, the player does not get an option to leave his entire bet on for the next spin.


Layout Roulette

like Martingale

like Neighbor bet

Neighbor bet (Neighbors):
A wager placed on five numbers in the close proximity on the roulette wheel (not on the felt), i.e. a particular number and two numbers to its immediate left and right on the wheel.

like Orphans

The French term describing a bet on particular numbers: 6, 17, and 34. These numbers are neighbors on the wheel, but on the felt they are far apart.
Another French term used to describe a wager placed on numbers neighboring on the wheel but are far apart from each other on the felt (layout). Electronic and online versions of roulette usually have these bets readily available so you don’t have to find and place them manually.
Outside Bet:

Another name for the Call bets, i.e. verbally announced bets encompassing the options explained in the Call bets definition.
Rapid roulette:
Sometimes also called a quick roulette. The roulette table equipped with player terminals to help with faster placing of the bets.
