Roulette Terms Explained: Jackpot.bet Single-Zero Play

Roulette may be complicated for many players if they are unfamiliar with the basic terms. On Jackpot.bet’s single-zero wheel, understanding Roulette terms like straight-up, split, and French rules such as En Prison helps you play smarter.
Knowing these key terms gives you the framework to follow the action, place informed wagers, and enjoy each spin with confidence.
In this guide, we will explain essential Roulette terminology and how each bet works so that you can approach every round with clarity on Jackpot.bet.
Roulette Basics: Table, Wheel, and Gameplay
These fundamental Roulette terms appear in almost every round, and give you the framework for everything else that happens on the table. The most common terms are:
Roulette Wheel (Single-zero)
The wheel is the centerpiece of the game, containing numbers 0 through 36 arranged in a non-sequential order.
Jackpot.bet uses the European single-zero wheel, which has one green zero pocket and no double zero. This lowers the house edge to 2.70% and gives players better odds than American Roulette versions.
Table Layout
The table is divided into two main sections: the inside area with the numbered grid from 0 to 36, and the outside area, which has broader betting options like red/black or dozens.
Croupier/Dealer
In live Roulette, the dealer spins the wheel, releases the ball, and announces the winning number. In online versions, this process is automated or managed by a live host.
Chips and Bankroll
Roulette color-coded chips to keep track of your wagers. Your bankroll is the total amount you plan to use for the session, and managing it well allows you to play Roulette responsibly while making smarter bets.
House Edge
Every wager carries a casino advantage, known as the house edge. In European Roulette, this comes from the single zero, which causes certain bets to lose when it appears. On Jackpot.bet, the house edge remains a competitive 2.70%.
Inside and Outside Bets: Core Betting Terms on Jackpot.bet
Every Roulette bet falls into one of two main categories, inside bets or outside bets. The main difference is where the bet is placed on the table and how many numbers it covers.
Inside bets are for the smaller sections of the wheel; they often come with higher Roulette payouts but lower odds.
On the other hand, outside bets cover larger sections. They offer more frequent wins with smaller returns.
Inside Bets
Inside bets are placed on the grid in the center of the table. They suit players chasing bigger payouts and willing to take on more risk.
-
Straight-up: A wager on a single number, including zero. It’s the highest payout in Roulette at 35:1.
-
Split: A bet on two close numbers by placing the chip on the line between them. Pays 17:1.
-
Street: A bet on three numbers in a row. Pays 11:1.
-
Corner (Square): Covers four numbers that meet at one intersection. Pays 8:1.
-
Six line (Double street): Covers two adjacent rows, for a total of six numbers. Pays 5:1.
Pro Tip: Higher payouts might come with lower odds. You may mix inside and outside bets to balance risk and reward.
Outside Bets
Outside bets are placed on the boxes surrounding the numbered grid. They cover broader outcomes and tend to appeal to players who prefer steadier, lower-risk play.
-
Red/Black: Betting on the winning number’s color. Even-money payout (1:1).
-
Odd/Even: Betting on whether the winning number will be odd or even. Pays 1:1.
-
Low/High: Covers either low numbers (1-18) or high numbers (19-36). Pays 1:1.
-
Dozens: Covers one of three 12-number ranges (1st 12, 2nd 12, or 3rd 12). Pays 2:1.
-
Columns: Represents one of the table's three vertical columns. Pays 2:1.
Pro Tip: Outside bets might win more often but pay less. This is a great Roulette strategy as you may focus on these bets to stretch your bankroll longer.”
Advanced European Roulette Terms
European Roulette offers a few additional words and bet kinds that might provide variation to your play once you've mastered the fundamentals.
In many European-style versions, such terms appear often, and knowing them helps you play with more confidence:
En Prison
A French rule applied to even-money bets when the ball lands on zero. Instead of losing immediately, your stake is “imprisoned” for the next spin.
If it wins on that spin, you get your original stake back without profit.
La Partage
Another French rule for even-money bets. When zero hits, you immediately recover half your stake and lose the other half.
La Partage and En Prison cut the house edge from 2.70% to about 1.35% on even-money bets.
Racetrack and Call Bets
A racetrack layout covers sections of the wheel rather than the table grid, often used for “call bets” (Bets announced to the dealer rather than physically placed in time).
Common examples include:
-
Voisins du Zéro: Covers 17 numbers surrounding zero on the wheel.
-
Tiers du Cylindre: Covers 12 numbers opposite zero on the wheel.
-
Orphelins: The 8 numbers not included in the two sections above.
-
Neighbour bets: A chosen number plus the two numbers on either side of it on the wheel.
French Bet Names
Some bet types have traditional French names that you might see on specific tables or in classic guides.
For example, a straight-up bet is En Plein, a split is Cheval, and a corner is Carré. While not necessary for play, these names aid in the recognition of conventional phrases.
Conclusion
Knowing the key Roulette terms makes it easier to follow the action, understand the table layout, and choose the bets that suit your style.
From the common inside and outside wagers to the advanced call bets and French rules found in European play, each term adds depth to the game.
Roulette on Jackpot.bet gives every spin strong payout potential. And with these Roulette terms in mind, you can approach each round with clarity, confidence, and a better sense of your options.
Frequently Asked Questions About Roulette Terms on Jackpot.bet
What are the bets called in Roulette?
Roulette bets are generally divided into two categories: inside bets and outside bets. Inside bets cover individual numbers or small groups, like a straight-up, split, or corner.
In contrast, outside bets cover larger sections of the table, such as red/black, odd/even, dozens, or columns.
What does “Impair” mean in Roulette?
“Impair” is French for “odd.” On European tables, you might see Impair (odd) and Pair (even) as the labels for odd/even betting boxes.
Betting on Impair means you’re wagering that the winning number will be odd.
What do 1st, 2nd, and 3rd 12 mean in Roulette?
These refer to dozens bets, which cover one of three 12-number ranges on the table.
The 1st 12 covers numbers 1-12, the 2nd 12 covers 13-24, and the 3rd 12 covers 25-36. Each dozen bet pays 2:1 if it wins.
What is the difference between inside and outside bets?
Inside bets have lower odds but bigger returns since they target fewer numbers and are placed on the numbered grid.
Outside bets are placed on the outer boxes, covering larger sections of numbers for more frequent but smaller wins.
