Roulette odds
Every bet, the same edge.
Straight up or red, dozen or split — pick a wheel and a bet and see the real numbers. The surprise: the house edge does not change with your choice.
The idea
The rules matter. The strategy does not.
On a European wheel every single bet carries the same 2.70% house edge. American roulette doubles it with a second zero; French roulette softens it with the partage rule. What never helps is your betting pattern — it only shifts the variance, not the long-run result.

Whichever bet you pick, the house edge is 2.70%. On average you lose 0.27 € per spin. The only thing that changes anything is the rules, not your strategy.
On European roulette EVERY bet has the same house edge: 2.70%. Straight up or red, it makes no difference. 'Strategy' does not exist — it only changes the variance, not the long-run result.
