Wheel Variants

European, American and French wheels look almost identical at a glance — same numbers, same colors, same basic layout — but the small differences between them add up to a real difference in house edge. Add in the enhanced multiplier formats some live studios run on top of the standard wheel, and picking the right table is worth ninety seconds of reading before you sit down. This page breaks down all three core wheel types plus the enhanced live formats, with the actual numbers behind each one rather than a vague better-odds claim.

European Roulette: The Standard

A European wheel carries 37 pockets: the numbers 1 through 36, split evenly between red and black, plus a single green zero. That single zero is where the house edge comes from — on every bet except the specific French rules covered below, the house edge sits at 2.70%, meaning that over a large number of spins, the wheel returns about 97.30% of everything wagered on it. It’s the standard wheel used across most of Spino’s RNG tables and a large share of the live ones.

American Roulette: The Extra Pocket

An American wheel carries 38 pockets: the same 1 through 36, plus both a single zero and a double zero. That second green pocket doesn’t change what any bet pays — a straight-up number still pays 35 to 1 on either wheel — it just adds one more losing outcome for every bet that isn’t zero, which pushes the house edge to roughly 5.26%, almost double the European figure. Given a straight choice between the two, the European wheel is the mathematically better seat for the exact same bets and the exact same payouts.

French Roulette: La Partage and En Prison

French roulette uses the same 37-pocket single-zero wheel as the European version, but adds one of two special rules to even-money bets specifically (red/black, odd/even, high/low). La Partage returns half your stake automatically if the ball lands on zero; En Prison instead holds your stake in play for one more spin, returning it in full if that next spin wins and taking it if it doesn’t. Either rule cuts the house edge on those specific even-money bets to about 1.35% — roughly half the standard 2.70% — making French roulette the best value on the floor for players who stick mainly to outside bets.

Enhanced Live Formats

Some live studios run enhanced roulette formats on top of the standard European wheel — most commonly a version that applies random multipliers to a handful of straight-up numbers before each spin, boosting the payout on any winning number the multiplier lands on well beyond the standard 35 to 1. The base wheel, the base odds and the base house edge underneath these formats stay the same as standard European roulette; the multiplier is an added layer on specific outcomes, not a change to how often the ball lands where it lands.

Comparing the House Edge

Lined up side by side, the difference between the best and worst of the three wheel types, over a long session, is meaningfully larger than most players expect from what looks like a small layout change:

  • American roulette (double zero): 5.26% house edge.
  • European roulette (single zero): 2.70% house edge.
  • French roulette, La Partage or En Prison bets: about 1.35% house edge on those even-money bets.

Which Wheel to Pick

If a table or a live lobby gives you a straight choice, European over American is close to a free upgrade — same bets, same payouts, lower edge, no downside. French roulette is the strongest pick specifically if you play outside, even-money bets regularly; if you mostly play inside numbers, the La Partage and En Prison rules don’t apply and French plays identically to European.
