Roulette is one of the easiest casino games to pick up and one of the most important to play the right version of, because the wheel you sit down at decides the house edge, and that decides how much you're likely to keep. The best online roulette sites UK players use give you the low-edge versions as standard, a good choice of live-dealer tables, and stakes that suit both a casual flutter and something more serious.
The basics never change. You're betting on where a ball lands on a spinning numbered wheel, anything from a single number to the broad even-money bets like red or black, odd or even. What does change between versions is how many zeros are on the wheel, and that one small thing makes a big difference to your odds over time. It's the most useful thing a roulette player can understand.
The versions, and why the wheel matters
- European Roulette: one zero and a house edge of 2.7%. This is the standard game in the UK and the one to go for by default.
- French Roulette: also a single zero, but with the La Partage rule that gives you back half your even-money stake if the ball lands on zero. That drops the edge on those bets to about 1.35%, the best odds in roulette, so it's worth seeking out.
- American Roulette: adds a second, double-zero pocket, which shoves the house edge up to 5.26%, nearly double the European game. Give it a miss whenever there's a European or French table going.
- Live and Lightning Roulette: real-dealer wheels on an HD stream. Lightning throws random multipliers of up to 500x onto single numbers, trading a slightly higher edge for the chance of a much bigger win.
The bets you can place
Roulette bets split into two groups, and knowing them helps you pick a style that suits you. Inside bets sit on the numbers themselves: a straight-up on a single number pays 35 to 1 but lands rarely, while splits, corners and streets cover several numbers at once for shorter odds. Outside bets sit around the edge: red or black, odd or even, and high or low all pay even money and come up close to half the time, while columns and dozens cover a third of the wheel. There's no bet that beats the house edge, that's fixed by the wheel, but even-money outside bets give you the steadiest ride, and they're where the French La Partage rule saves you the most. Straight-up bets are the ones to back if you're chasing a bigger, rarer win.
What we look for in a roulette site
- Low-edge versions: European at the very least, ideally French with La Partage, and easy to find.
- Live tables: a good choice of real-dealer wheels from Evolution or Playtech, including Lightning and Immersive.
- Table limits: a range of stakes so small and large bankrolls both have somewhere to play.
- Payout speed: quick, reliable withdrawals so any wins reach you without hanging around.
