Understanding American Roulette Numbers and Layout

American roulette numbers include 1 through 36, plus a single zero and a double zero, making 38 pockets on the wheel. This layout increases the house edge compared to European versions, which only have a single zero. The arrangement alternates red and black numbers, with zeros in green.

The placement of numbers on the wheel is not sequential, designed to balance high, low, odd, and even distributions. Knowing how the numbers are positioned helps players understand betting options and the game’s statistical structure. The double zero is the key difference affecting odds and payouts.

Number Sequence and Wheel Design

The American roulette wheel follows a specific number order: 0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1, 00, 27, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14, 2. This non-sequential layout aims to randomize outcomes.

Numbers are alternately colored red and black, with both 0 and 00 in green. The table layout arranges numbers in three columns of 12, allowing for various inside and outside bets. The double zero increases the house edge to 5.26%, the highest among standard roulette variants.

Betting Options Based on Numbers

Players can place inside bets directly on American roulette numbers, such as straight-up (one number), split (two), street (three), or corner (four). These offer higher payouts, like 35:1 for a single number hit, but lower winning probability.

Outside bets cover broader groups—red/black, odd/even, dozens, or columns. These pay 1:1 or 2:1 but have better odds. However, the presence of 0 and 00 means these bets lose when the ball lands on either zero, increasing the house advantage over time.

How the Double Zero Affects Odds

The addition of the double zero is the defining feature of American roulette. It reduces the probability of hitting any single number from 1 in 37 to 1 in 38, while keeping payouts at 35:1. This discrepancy creates the 5.26% house edge.

  • Single number hit probability: 2.63%
  • House edge: 5.26% due to 0 and 00
  • Even-money bet win chance: ~47.37%
  • Payouts remain unchanged from European roulette
  • Higher risk for long-term players
