Roulette Double Zero: How It Affects Your Odds
Roulette double zero is a defining feature of American roulette, adding a 38th pocket to the wheel. This extra pocket increases the house edge and reduces the player’s chances of winning compared to European or French versions. Understanding its impact helps players make smarter game choices.
The presence of both 0 and 00 changes the mathematical odds across all bets. While payouts remain the same, the added pocket means lower probability of hitting any single number. This subtle difference has a significant long-term effect on player returns.
American vs. European Wheel Layout
The American roulette wheel includes both 0 and 00, positioned opposite each other, with numbers arranged in a specific alternating pattern. The European wheel has only a single zero, resulting in 37 pockets. This single difference increases the house edge from 2.7% to 5.26%.
The layout affects not just odds but also call bets. Many European-specific bets like voisins or orphelins aren’t available in standard American games. Players lose access to advanced betting options that add variety to gameplay.
- American wheel: 38 pockets (0, 00, 1–36)
- European wheel: 37 pockets (0, 1–36)
- House edge: 5.26% in American, 2.7% in European
- Same payouts despite different odds
- Call bets rarely available in American versions
Impact on Common Bet Types
All standard bets pay the same in American and European roulette, but the double zero reduces winning probability. A straight-up bet has a 1 in 38 chance in American versus 1 in 37 in European. Even-money bets like red or black now have two losing zero pockets instead of one.
This means players lose more often over time. For example, betting on black will lose on both 0 and 00, doubling the chance of a zero outcome compared to single-zero games. The effect compounds with extended play.
- Straight-up bet odds: 2.63% (American) vs. 2.70% (European)
- Even-money bets lose on both 0 and 00
- Dozen and column bets have lower hit rates
- No 'la partage' or 'en prison' rules in most American games
- Higher long-term losses due to increased house edge
Why Some Players Still Choose Double Zero
Despite the worse odds, American roulette remains popular in some regions and live dealer formats. Some players prefer the faster pace or are unaware of the mathematical disadvantage. Others enjoy the game’s layout or are drawn to its presence in high-profile casinos.
Additionally, some online platforms offer American roulette with side bets or bonus features to increase engagement. However, these additions rarely offset the higher house edge. Knowledgeable players typically opt for single-zero versions when available.
