Online roulette looks like one game, but it is really a family of close cousins that pay the same odds while offering very different value. The gap between them comes down to how many zeros sit on the wheel.

European, American, and the House Edge

A European wheel carries a single zero across thirty seven pockets. An American wheel adds a second zero, the double zero, for thirty eight pockets in total. Both pay a straight up winner at thirty five to one, which sounds fair until you count the pockets. That mismatch between the true number of outcomes and the payout is the house edge, and the extra pocket on the American wheel roughly doubles it. A player who chooses the single zero version is not being lucky. They are simply accepting a smaller built in disadvantage on every spin.
