Roulette is one of the most recognisable table games in any United Kingdom casino, whether you play on the high street or through an online operator. Yet many players do not realise that the two most common variants, European and American roulette, are not created equal. The differences look small on the surface, but they translate into a meaningful gap in the house edge and your long-term returns. This comparison breaks down the wheels, the rules and the maths so you can choose with confidence. Check out additional details at UltimateWins 20 free spins on registration.
The Wheels and the Numbers That Matter
European roulette uses a single-zero wheel with 37 pockets numbered zero to 36. American roulette adds a second green pocket, the double zero, giving 38 pockets in total. That single extra slot changes everything about the odds.
On a European wheel, the probability of hitting any single number is 1 in 37, or roughly 2.70%. On the American wheel it is 1 in 38, or about 2.63%. Those tiny shifts sound trivial, but they tilt the balance of the entire game toward the house.
The house edge tells the real story. European roulette carries a house edge of 2.70% on most bets. American roulette almost doubles that to 5.26%. Over a session, a player staking £100 on even-money bets would expect to lose around £2.70 at a European table compared with £5.26 at an American one.
For anyone playing regularly, that gap compounds. A player wagering £1,000 across a month faces an expected loss of roughly £27 in European roulette, versus £52.60 in the American version. The same stakes, the same enjoyment, but nearly double the cost.
Rules, Bets and the Special Cases
Most bets are identical in name and payout across both variants: straight up, split, street, corner, line, red or black, odd or even, and high or low. The payout odds are the same too, which is exactly why the extra pocket matters. You are paid as though there were 36 numbers, but the American wheel has 38 pockets.
European tables often offer the La Partage and En Prison rules. La Partage returns half your stake on even-money bets when the ball lands on zero. En Prison lets you leave an even-money bet for the next spin. These rules push the house edge on even-money bets down to around 1.35%, making European roulette one of the fairest table games available.
American roulette occasionally features a five-number bet covering 0, 00, 1, 2 and 3. It is best avoided, because its house edge is a punishing 7.89%. Even experienced players rarely touch it.
Some American tables now offer a “surrender” rule on even-money bets, which reduces the edge on those wagers to about 2.63%. It narrows the gap but never closes it. The double zero always leaves American roulette at a disadvantage.
Which Should You Choose?
For players in the United Kingdom, European roulette is almost always the smarter pick. Lower house edge, better odds on every bet, and the availability of La Partage make it the clear favourite. Most online operators default to the European wheel, and live dealer tables usually follow suit.
American roulette still has its place for variety, and some players enjoy the faster, more volatile feel. But if value matters, the numbers speak plainly. A house edge of 2.70% against 5.26% is a difference worth respecting.
Check the wheel before you place a bet. Look for the single zero, confirm whether La Partage applies, and read the table rules. A minute of checking can save pounds over a session, and it is the simplest way to play roulette on your own terms. Enjoy the game responsibly, and remember that every wager carries risk.
