Together these sectors cover the entire wheel
Sector betting covers groups of numbers that are physically adjacent on the roulette wheel (not the table layout). Popular sectors include Voisins du Zéro (17 numbers around zero), Tiers du Cylindre (12 numbers opposite zero), and Orphelins (8 remaining numbers).
No. Sector betting does not change the house edge - it remains 2.70% on European wheels and 5.26% on American wheels. However, it allows you to bet on physically adjacent numbers, which some believe can be exploited if a wheel has bias.
A neighbors bet covers a chosen number plus typically 2 numbers on each side of it on the wheel (5 numbers total). Each number gets a straight-up bet. This is popular for players who believe certain wheel sections hit more often.
Voisins du Zéro ("Neighbors of Zero") covers 17 numbers from 22 to 25 on the wheel, centered around zero. It requires 9 chips placed on specific splits and corners, covering about 46% of the wheel.
