Why European always beats American
The payouts are the same on both wheels. What changes is the chance of winning, because American roulette adds a second green pocket, the double zero ("00"). With 38 pockets instead of 37, every bet wins slightly less often at the same odds.
The result: European has a house edge of 2.70% on every bet. American has 5.26% on every bet (with one exception: the "five-number bet" on American, which somehow has a 7.89% edge). For the same stake, you lose money roughly twice as fast on American as on European. There is no version of roulette mathematics where playing American is the better choice. Always look for European, and check the wheel before you sit down.
The "even money" misconception
Red or black, odd or even and high or low are called "even money" bets because they pay 1 to 1. They are not 50/50. On a European wheel, red covers 18 of 37 pockets, a 48.65% chance. The missing 1.35% is where the house edge comes from.
This catches out a lot of players. They see "even money" and assume a coin flip. The gap between a 48.65% chance and a 1 to 1 payout is exactly the casino's edge, and you pay it on every spin.
The truth about betting systems
Because roulette's payouts and probabilities are fixed, no betting system (Martingale, Fibonacci, D'Alembert, Labouchère) can change the long-term expected value. Every bet carries the same 2.7% (European) or 5.26% (American) edge against you. Systems only change the pattern of wins and losses.
