It is the same game with one tiny difference that doubles what it costs you: the number of green zero pockets. The American wheel has two (0 and 00); the European wheel has one (0). That single pocket is the difference between a 5.26% and a 2.70% house edge.
| American | European | |
|---|---|---|
| Pockets | 38 (1–36, 0, 00) | 37 (1–36, 0) |
| Green zeros | Two (0 and 00) | One (0) |
| House edge (all bets) | 5.26% | 2.70% |
| Straight-up payout | 35:1 | 35:1 |
Payouts are identical on both wheels — a single number still pays 35:1. But the American wheel has one extra losing pocket (the 00) while paying out the same as if it weren't there. That gap between true odds and payout is exactly where the house edge comes from, and adding the 00 nearly doubles it, from 2.70% to 5.26%.
Bet $100 worth of spins. On a European wheel you expect to lose about $2.70; on an American wheel, about $5.26 — nearly twice as much, for the identical game. Over a night of play that difference compounds fast.
Always play the single-zero European wheel when it is available. Many casinos offer both; the European table is sometimes in a higher-limit area, but the better odds are usually worth it. No betting system changes these numbers — the wheel you sit at does.

The American wheel has 38 pockets including both 0 and 00 (5.26% edge). The European wheel has 37 pockets with a single 0 (2.70% edge). Fewer zeros, better odds.
European, by a lot — 2.70% vs 5.26%, almost half the cost on every bet.
It adds a losing pocket (37 → 38) while payouts stay the same, which nearly doubles the house edge from 2.70% to 5.26%.
