The Differences Between American and European Roulette

The iconic roulette wheel is the most famous image of casino gambling worldwide. While the fundamental idea —betting on where the white ball stops— is the same across the globe, not all tables are created equal. The casino world features two main versions that dominate the casino floors: the American and European layouts. Knowing the massive variations between the two styles is incredibly important for any player wanting to maximize their chances of winning.

The Green Zeroes: The One Massive Difference

The primary physical distinction between the wheels is the number of green pockets. A French or Euro wheel has exactly thirty-seven slots: the standard 1-36, plus a single green zero (0). On the other hand, the American Roulette wheel contains 38 spaces. It features the regular 1-36, a single zero, plus a devastating extra pocket: the double zero. This one additional space might not look like a big deal to a beginner, but mathematically, it changes the entire game.

The Mathematical Consequence on the House Edge

On the roulette table, the mathematical returns are based as if the zero did not exist. For instance, guessing the exact number pays out at 35:1, on both the American and European tables. Since the Euro version only has one green slot, the casino's built-in mathematical advantage sits at exactly 2.7%. But, since the US version adds a second guaranteed losing pocket for outside bets (the 00) but pays the same odds, the casino's advantage skyrockets to a massive 5.26%.

• Always choose European Roulette if you have the choice. It makes no sense to play with a double zero.
  
• The 0-00-1-2-3 wager is unique to the US wheel and carries a horrendous house edge, with a massive 7.89 percent margin.
  
• French roulette games use the En Prison mechanic, which reduces the casino margin on even-money bets to a tiny 1.35%.
  

Side-by-Side Analysis: American vs European

To summarize the mathematics, please review the comparison table below. It breaks down the exact reason why pros always prefer the French or Euro games.

Feature	Euro Layout	Double Zero Wheel
Spaces on Wheel	37 (1-36 plus 0)	38
Zero Slots	One (0)	2
Casino Advantage	Low at 2.70%	High at 5.26%
Lowest Possible Edge (with La Partage)	Incredible 1.35%	Always 5.26%

In conclusion, the American wheel's extra slot is nothing more than a casino trick to double their profits from uninformed players. No matter if you are wagering at a lavish casino in Las Vegas or spinning the wheel at an online casino from your smartphone, your primary strategy must always be finding a European Roulette table. Skipping the 00 wheel is the simplest method to instantly double your long-term returns.
