What Is European Roulette?

European roulette is the single-zero variant of roulette, played on a wheel of 37 pockets numbered 0 through 36, with a fixed house edge of 2.70%. That 2.70% is the defining number of the variant: it is the long-run cost the table holds on every bet you place, and it does not change between a straight-up single number and an even-money red or black wager.

The single green zero is the only structural difference between European roulette and the American game, which adds a second zero, the 00. Everything else — the red and black numbers, the inside and outside bets, the payouts — is shared. European roulette is the standard variant across most of the world, and for even-money play it is the default best-odds table. That single zero is the whole story behind why European roulette gives players better odds than its American cousin.

Why Does European Roulette Have the Best Odds?

European roulette holds a 2.70% house edge — exactly half the 5.26% edge of American roulette — because it carries only one zero instead of two. The zero is the one pocket that does not pay out on even-money bets such as red, black, odd, or even. American roulette adds a second non-paying pocket, the 00, which lifts the edge to 5.26%, nearly double the cost on every spin.

Variant	Pockets	Zero configuration	House edge
European	37	Single zero (0)	2.70%
American	38	Double zero (0, 00)	5.26%

In plain cash terms, the gap is easy to see. On a single £10 even-money bet, the expected long-run cost is about 27 pence on a European table against roughly 53 pence on an American one. The maths is the same on every spin, which is why variant choice matters more than any betting system. For the full breakdown of how each wager pays, the roulette odds and roulette payout guides set out the numbers, and the European vs American roulette comparison explains the edge side by side.

French roulette lowers the effective edge further still, to 1.35% on even-money bets, through the La Partage rule that returns half your even-money stake when the ball lands on zero. On the standard inside and outside bets you will meet most often, though, European is the strongest widely available choice. The lower edge comes straight from the wheel itself, so the layout is worth understanding before you place a bet.

How Is the European Roulette Wheel and Table Laid Out?

The European roulette wheel holds 37 pockets in a fixed, balanced sequence, and its betting table places the single zero above a three-column grid of the numbers 1 to 36. The wheel order begins 0, 32, 15, 19, 4, 21, 2, 25 and continues around the rim, alternating red and black with the single green zero set apart.

Those numbers are not arranged in counting order. They are positioned so that high and low, and odd and even, are spread as evenly as possible around the wheel, so no quarter of the rim clusters one type of result. The betting table, by contrast, follows the orderly standard layout: a three-column, twelve-row grid of 1 to 36 with the single zero at the top, ringed by the outside bets — red and black, odd and even, high and low, the dozens, and the columns. Because there is one zero rather than two, the European table simply omits the extra 00 box found on American felt. Around the edge of that table sits a feature American tables usually drop: the racetrack for call bets.

What Are the European Roulette Call Bets?

European roulette call bets are wagers on groups of numbers that sit next to each other on the wheel, placed through the oval racetrack rather than the main number grid. The racetrack mirrors the wheel sequence, so a single bet can cover a whole sector of neighbouring pockets in one move — something the standard felt grid cannot do, because numbers that are adjacent on the wheel are scattered all over the betting layout.

There are three classic call bets, each covering a defined sector of the wheel:

• Voisins du Zéro (“neighbours of zero”) covers the 17 numbers around the green zero, running from 22 to 25 across the top of the wheel, as a single multi-chip bet.
• Tiers du Cylindre (“third of the wheel”) covers the 12 numbers on the opposite side, from 27 to 33.
• Orphelins (“orphans”) covers the 8 numbers left out of the other two sectors.

These wheel-sector bets are a hallmark of European and French roulette and are rarely offered on American tables. Every one of them is playable, free, in the simulator above.

Prefer the higher-variance, double-zero game, or the lowest-edge table of the three? Both have their own version: the American roulette simulator carries the steeper 5.26% edge, while the French roulette simulator brings the La Partage rule and the friendliest 1.35% even-money edge.

Frequently Asked Questions

Is European roulette better than American roulette?

European roulette gives better odds than American roulette because it has a 2.70% house edge against American’s 5.26%. The difference comes from the single zero: European tables carry one zero, while American tables add a second zero, the 00, which doubles the long-run cost on even-money bets. The red and black numbers, payouts, and bet types are otherwise identical.

What is the house edge in European roulette?

European roulette has a fixed house edge of 2.70% on every bet. That figure comes from the single green zero, the one pocket on the 37-pocket wheel that does not pay even-money bets. The edge stays the same whether you back a single number or an even-money wager such as red, black, odd, or even.
