Roulette offers more than the familiar inside and outside bets displayed on the betting layout. On many European and French roulette tables, players can also choose announced bets based on the physical arrangement of numbers around the wheel. One of the best-known approaches is sector betting, where wagers cover specific sections of the wheel instead of individual numbers or table positions.
For beginners, sector betting may seem unfamiliar because the selected numbers are grouped according to their location on the roulette wheel rather than their numerical order on the betting grid. Once players understand how the wheel is divided into recognized segments, these wagers become much easier to follow and offer another way to explore the game.
At Gambling Zone, we explain what sector betting is, how wheel segments are organized, and why these traditional wagers remain popular in European roulette.
Why the Roulette Wheel Is Divided Into Sections
The numbers on a roulette wheel are arranged in a carefully designed sequence rather than simple numerical order. This layout creates distinct groups of neighboring numbers, making it possible to place wagers based on physical wheel sections instead of positions on the betting table.
Learning how these sections are arranged provides the foundation for understanding sector betting and other wheel-based wagers.
What Is Sector Betting?
Sector betting is a method of placing wagers on a recognized section of the roulette wheel instead of selecting individual numbers from the betting layout.
Each sector represents a group of neighboring pockets positioned together on the wheel. Rather than placing multiple individual bets manually, players select the sector, and the required betting combination is applied automatically by the dealer or software.
The most common wheel sectors include:
- Voisins du Zéro.
- Tiers du Cylindre.
- Orphelins.
- Jeu Zéro.
Each covers a different group of numbers and uses its own established betting pattern.
How Wheel Segments Are Used

How Wheel Segments Are Used
Unlike standard inside bets, sector bets are determined entirely by the position of numbers around the roulette wheel.
Players begin by selecting a recognized wheel sector. The dealer in a land-based casino, or the software in an online game, then places the appropriate combination of wagers automatically. This removes the need to manually place chips across several different areas of the betting layout.
The process is especially useful for traditional announced bets because it allows players to focus on sections of the wheel rather than searching for individual numbers.
How Sector Bets Differ From Standard Roulette Bets
Traditional roulette wagers are placed directly on the betting grid, where numbers appear in numerical order. Sector bets work differently because they follow the physical arrangement of the wheel.
Instead of covering numbers that sit together on the table, sector bets cover neighboring pockets that share the same area of the wheel. These wagers often involve multiple chip placements and are based on established announced betting combinations rather than individual selections.
Although the betting method changes, the rules of roulette, the spinning wheel, and the random outcome remain exactly the same.
Where Can You Find Sector Betting?
Sector betting is most closely associated with European Roulette and French Roulette, where announced bets have long been part of the traditional game.
Many live dealer roulette tables also include sector betting through a racetrack layout, allowing players to select wheel segments with a single click. Some online roulette games offer the same feature, although availability varies depending on the software provider and casino.
Simplified roulette games and many American Roulette tables may not include these betting options, so players should check the table information before play.
Understanding the Wheel Beyond the Betting Layout

Understanding the Wheel Beyond the Betting Layout
Learning about sector betting helps players appreciate that the roulette wheel itself plays an important role in several traditional betting methods. Rather than focusing only on the numbered betting grid, these wagers encourage players to understand how the physical arrangement of pockets creates recognized wheel segments and announced bets.
This knowledge also makes it easier to understand related betting options, including neighbours bets and racetrack betting, which are also based on the layout of the wheel instead of the betting table.
Exploring Another Dimension of Roulette Betting
Sector betting demonstrates how roulette combines a straightforward game with a wide variety of wagering options. By grouping numbers according to their position on the wheel, these bets offer an alternative way to participate without changing the game's core rules or procedures.
Whether playing online or in a land-based casino, understanding sector betting provides greater insight into one of roulette's most distinctive traditional features.
