The classic game of roulette is perhaps the most recognizable symbol of casino gambling worldwide. While the fundamental idea —guessing where a small ball will land— remains identical everywhere, not all roulette wheels are identical. The casino world features two main versions that dominate the casino floors: American Roulette and European Roulette. Understanding the critical differences between the two styles is absolutely essential for anyone trying to protect their bankroll.
The Green Zeroes: The One Massive Difference
The absolute biggest variation between American and European roulette lies in the layout of the wheel itself. A French or Euro wheel contains 37 numbers: numbers one to thirty-six, and one single green zero. On the other hand, the American Roulette wheel features 38 total pockets. It features the same numbers 1 through 36, the single green zero (0), plus a devastating extra pocket: the 00. This one additional space might seem insignificant to an amateur player, but statistically, it alters the odds massively.
The Mathematical Consequence on Your Winning Odds
On the roulette table, the mathematical returns are strictly designed as if the zero did not exist. For example, hitting a single number pays out at 35:1, regardless of which version you play. Because the European wheel only has one green slot, the casino's built-in mathematical advantage sits at exactly 2.7%. But, because the double zero wheel has 38 total spaces without increasing the payouts, the casino's advantage skyrockets to exactly 5.26%.
Always choose European Roulette when gambling online. It makes no sense to play with a double zero. The 0-00-1-2-3 wager only exists on the double zero layout and is the absolute worst bet, giving the house a 7.89% advantage. Some European tables offer the 'En Prison' or 'La Partage' rules, which reduces the casino margin on red/black wagers down to an incredible 1.35%.

To wrap it up, the addition of the double zero is nothing more than a casino trick to drain your bankroll faster from casual tourists. If you are playing at a lavish casino in Las Vegas or spinning the wheel at an online casino from your smartphone, your first goal is required to be choosing the 37-pocket wheel. Skipping the 00 wheel is the easiest and most effective way to massively boost your winning probabilities.
