Roulette Variants Explained: European, American and the Rest

Roulette looks like one game, but the wheel a table uses changes the house edge by more than a full percentage point, and the side rules layered on top of it can change it further. Knowing which variant is on a table before sitting down is a more useful skill than any betting system, because it is the one factor a player can actually control. This guide walks through the main variants available at a typical Canadian-facing online casino, using Winstoria's live roulette section as a reference point for how the format usually gets presented.

European Roulette: the Baseline

European roulette uses a single zero pocket alongside numbers 1 through 36, which puts the house edge at 2.70% on standard outside and inside bets. It is the format most online casinos default to and the one worth learning first, since every other variant is a modification away from it. If a table's rules page doesn't specify American or French, it is almost always European by default — worth confirming rather than assuming, since the difference compounds over a long session.

American Roulette: the Double Zero

American roulette adds a second zero pocket, pushing the house edge to 5.26% — nearly double the European figure — with no corresponding change to payouts. The wheel looks almost identical at a glance, so the extra pocket is easy to miss unless a player counts the numbers or checks the table's stated variant. There is no scenario where American roulette pays better than European roulette; the only reason to choose it is unavailability of the European table at that moment.

French Roulette and La Partage

French roulette uses the same single-zero wheel as the European version but adds one or both of two rules: La Partage, which returns half of an even-money bet if the ball lands on zero, and En Prison, which holds the bet for one more spin instead. Either rule cuts the house edge on even-money bets (red/black, odd/even, high/low) to roughly 1.35%, the lowest of any common variant. French roulette tables are less widely offered than European or American ones, so it is worth checking a live lobby's rules page specifically for "La Partage" or "En Prison" rather than assuming a French-labelled table includes them.

Live Dealer Roulette vs RNG Tables

Beyond the wheel type, roulette online splits into two delivery formats. RNG (random number generator) roulette runs entirely in software, with results generated instantly and no visible wheel spin beyond an animation. Live dealer roulette streams a real wheel and dealer from a studio, with the same physical mechanics as a land-based table and a visible spin that takes longer per round. The house edge is set by the variant, not the delivery format, so a European RNG table and a European live table carry the same theoretical edge — the choice between them comes down to pace and preference rather than value. Winstoria's live section runs roulette alongside blackjack, baccarat and studio game shows such as Crazy Time and Monopoly Live, with table limits starting low enough for a small-stakes session and rising from there.

Speed and Multi-Wheel Variants

Live studios also run faster formats — speed tables drop the betting window to roughly 20-25 seconds per round instead of the usual 30-40, and multi-wheel tables let a single bet apply across several wheels spinning in parallel. Neither changes the underlying house edge of the wheel type in use; they change how quickly a bankroll moves through rounds, which matters more for session budgeting than for the maths of any individual spin.

Choosing a Table as a Canadian Player

Three checks cover most of what matters before placing a first chip: confirm the wheel type (single vs double zero) from the table's own rules page, check whether La Partage or En Prison is active if it's labelled French, and match the table's minimum and maximum limits to a bankroll set in CAD ahead of time. Winstoria's live tables list their per-round limits directly in the lobby, which makes that last check straightforward before a table even loads. None of this determines any single outcome — a wheel with a lower house edge simply loses value more slowly over many rounds than one without.

FAQ

Which roulette variant has the lowest house edge?

French roulette with La Partage or En Prison active, at roughly 1.35% on even-money bets — lower than European's 2.70% and well under American's 5.26%.

Is American roulette ever a better choice than European?

No. The extra double-zero pocket increases the house edge with no offsetting change to payouts, so European or French tables are always the stronger choice when available.

Does live dealer roulette pay differently than RNG roulette?

No, not inherently. The house edge is determined by the wheel type (single or double zero, plus any French rules), not by whether the round is dealt live or generated by software.

What is the difference between La Partage and En Prison?

Both apply when the ball lands on zero. La Partage returns half of an even-money bet immediately; En Prison holds the full bet "in prison" for one more spin instead of refunding it, and returns it only if that next spin wins.
