The Differences Between European and American Roulette

If you stand next to a roulette table in a crowded casino, your eyes are immediately drawn by the bouncing white ball, the fast-paced betting action, and the excitement of the players. To a casual tourist, every single roulette table looks absolutely identical. You place your bets on a number, the wheel spins, and you hope to win. Yet, there is an incredibly important variation between the two main versions of the game: the American wheel and the European wheel. Learning which wheel is which is not just a fun fact; it is the single most important mathematical decision in the entire casino.

Spotting the Difference: The Mathematical Trap

The primary difference between American and European roulette is extremely easy to spot if you examine the layout. The European layout has 37 slots for the ball: the standard 36 numbers, and a single green zero (0). On the other hand, the American version features 38 total pockets: the numbers 1 through 36, a single green zero (0), and an additional green double zero (00). To an amateur, a single extra slot might seem completely insignificant. However, in the world of casino mathematics, that 38th slot is a massive advantage for the house that doubles the casino's profit margin.

Why American Roulette is a Trap: How the Double Zero Ruins Your Odds

To understand why the American wheel is terrible, you must understand the casino advantage. In both versions of the game, hitting an exact number always pays out at 35 to 1. In European roulette, your true odds of hitting that number are 1 in 37. Because the payout (35 to 1) is slightly less than the true odds, the casino holds a very reasonable house edge of exactly 2.70%. Now apply this to the Vegas wheel. The reward does not change, but thanks to the extra green slot, your true odds of winning are now 1 in 38. This single addition nearly doubles the casino's house edge to a terrible 5.26%. You are taking on significantly more risk for the exact same potential reward.

• 
  
• Actively hunt for the single zero wheel. Playing the American wheel gives the casino free money.
  
• Search for French Roulette rules. French roulette games feature these mechanics which refund half your even-money bet if zero rolls, dropping the house edge to an incredible 1.35%.
  
• Most online casinos offer both versions. It is foolish to ever click on an American roulette game when playing at an online casino.
  
• In physical Las Vegas casinos, European wheels are usually hidden in the high-limit VIP rooms because the casino wants tourists to play the terrible American odds.
  

Comparing the Wheels: The Math Breakdown

If you are still confused, look at this mathematical comparison. It clearly shows why the single zero game is the only logical choice than the double zero trap.

To summarize, there is zero benefit to ever play American Roulette if a European table is available. The American layout was created by casino operators to drain bankrolls faster from players who don't know the math. By paying attention to look for the double zero prior to playing, you can instantly cut the casino's advantage in half. Be a smart gambler: avoid the 00 at all costs.
