La partage is one of the most important roulette rules to understand because it changes what happens when zero lands on the wheel. Instead of losing a full even-money bet, you get half your stake back. That small rule makes a meaningful difference to bankroll impact, table value, and the effective house edge.
En prison roulette is a roulette rule, not a separate wheel. When zero lands on certain even-money bets, the stake is put “in prison” for the next spin instead of being lost right away. That matters because, in classic single-zero roulette, the rule can cut the house edge on those qualifying bets roughly in half.
Racetrack betting is a roulette betting method built around the wheel’s actual number order, not the rectangular number grid on the felt. It is most common on European and French-style roulette tables, where players use the racetrack to place sector bets like neighbors, Voisins du Zero, Tiers du Cylindre, and Orphelins more quickly. Availability, naming, and bet menus can vary by wheel type, casino, and jurisdiction.
In roulette, **voisins du zero** is a classic French announced bet that covers the 17 numbers around zero on a European wheel. Instead of placing every wager separately, the bet uses a fixed 9-chip pattern made up of splits, a trio, and a corner. If you play European roulette in a casino or live dealer room, understanding this term helps you read racetrack layouts, dealer calls, and total stake requirements.
Orphelins is one of roulette’s classic French call bets, but it confuses many players because it is built from the wheel, not from nearby numbers on the betting layout. On a standard single-zero wheel, it covers the eight “orphan” numbers left outside the two better-known sectors, Voisins du Zéro and Tiers du Cylindre. If you understand orphelins, dealer calls, racetrack betting, and stake sizing all make much more sense.
A **neighbors bet** in roulette is a wheel-based wager that covers one chosen number and the numbers next to it on the wheel, not the numbers beside it on the table layout. It is most common in European and French roulette, especially on tables with a racetrack or in live dealer interfaces. If you understand this one distinction, a lot of roulette betting language becomes much easier to follow.
High or low roulette is one of the simplest wagers on the roulette layout, but many new players still misunderstand what it covers. In standard roulette, it means betting that the winning number will land in either 1-18 or 19-36, with 0 and 00 usually losing. Knowing how high or low roulette works matters because the wheel type, table rules, and even-money exceptions can change the true cost of the bet.
Odd or even roulette is one of the simplest bets on the roulette table, but the wheel type behind it changes the value of the wager. You are betting that the next winning number will be odd or even, usually for a 1:1 payout. The important catch is that 0, 00, and 000 are not odd or even, so the table rules matter more than many beginners expect.
Red or black roulette is one of the simplest bets in the casino, but it is often misunderstood as a pure 50/50 wager. In practice, it is an even-money color bet on a roulette table, and the zero pockets are what change the odds. If you want to understand the layout, the payout, and why wheel type matters, this is the key bet to learn first.
A column bet is one of the core outside bets in roulette, covering 12 numbers in a single vertical lane on the table layout. It looks straightforward, but the wheel version behind the game—single-zero, double-zero, or triple-zero—changes the true odds and house edge. If you want to read a roulette layout properly, compare payouts, and avoid common betting mistakes, this is a useful bet to understand.
