Roulette

Roulette explained with the real numbers: what every bet pays, how often it wins, why the single-zero wheel costs half as much as the double-zero one, how French rules and live variants change the maths, and why no betting system beats the wheel.

Roulette wheels and bets: the essentials

Roulette is a wheel game where you bet on which numbered pocket the ball will land in. A European wheel has 37 pockets (1 to 36 plus a single zero) and an American wheel has 38, adding a double zero. Payouts are the same on both, so the extra pocket simply raises the house's share, as our European against American comparison shows.

Bets fall into two groups. Inside bets cover one to six numbers and pay more, from 35 to 1 on a straight up bet. Outside bets cover 12 or 18 numbers, such as dozens, columns and red or black, and pay 2 to 1 or even money. French and live tables also take call bets on sections of the wheel, such as voisins du zéro.

Roulette odds and payouts for every standard bet

Every standard bet is paid as if the wheel had 36 numbers. On a single-zero wheel that gap gives the house 1/37, or 2.70%, on every bet; on a double-zero wheel it is 2/38, or 5.26%. The chances below are counted from the pockets on a single-zero wheel.

Which roulette game to play: wheels, French rules and variants

Pick a single-zero wheel wherever you can. Better still for even-money bets is French roulette with the La Partage rule, which returns half an even-money stake when zero lands and cuts that bet's edge to 1.35%. Inside bets, dozens and columns keep the 2.70% edge.

Multiplier games trade base payouts for rare big wins. In Evolution's Lightning Roulette, one to five Lucky Numbers each round pay 50x to 500x on straight-up bets, but an unboosted straight up pays 29 to 1 instead of 35 to 1; UK operator game pages list its RTP at up to 97.30%. Mini roulette, with 13 pockets, carries higher edges than the standard wheel.

No staking pattern changes the edge on a single bet, so no system changes the edge overall. Wizard of Odds' simulations found Martingale, Fibonacci, d'Alembert and Labouchère players all lost at the house-edge rate; see our betting systems hub and the Wizard of Odds roulette guide (opens in a new tab) for the maths. Past numbers don't predict future spins either.

In Great Britain, RNG roulette must produce acceptably random results that match a real wheel's probabilities. Since 17 January 2025, autoplay is banned for all online casino games and each round must take at least 5 seconds. The £5 and £2 slot stake limits don't apply to roulette; each table sets its own limits. Live roulette uses a physical wheel streamed from a studio.

Frequently asked questions

What are the best odds in roulette?

Even-money bets on a French table with La Partage give the lowest edge, 1.35%, because half the stake comes back when zero lands. Otherwise, every bet on a single-zero wheel has the same 2.70% edge, whatever its payout. The bet with the highest chance of winning is an even-money bet, at 18 in 37. Our answer to what the best bet in roulette is goes through each option.

Is European roulette better than American roulette?

Yes, for cost. European roulette has one zero and a 2.70% house edge; American roulette adds a double zero, which raises the edge to 5.26% on most bets and 7.89% on the five-number top line. Payouts are the same, so the extra pocket only helps the house. At £10 a spin, that is about 27p against 53p a spin on average. See American roulette for the full comparison.

Does the Martingale system work in roulette?

No. Doubling after each loss produces lots of small wins, but a run of losses quickly hits your budget or the table limit, and one such loss wipes out many small gains. On a single-zero wheel, the chance of losing eight even-money bets in a row is about 1 in 207. Simulations show Martingale players lose at the same rate as flat bettors. Our Martingale page shows the numbers.

Is online roulette random?

Yes, at UK-licensed casinos. RNG roulette must produce results that are acceptably random and match a real wheel's probabilities, and the Gambling Commission requires games to be tested before release. Live roulette uses a real wheel and ball filmed in a studio. Neither version remembers past spins, so hot and cold numbers have no predictive value. Read more in RNG against live roulette.

What does a straight-up bet pay in Lightning Roulette?

An unboosted straight-up win pays 29 to 1, not the usual 35 to 1, according to Evolution's game page. The difference funds the Lucky Number multipliers of 50x to 500x that land on one to five numbers each round. Other bets, such as splits and red or black, pay their normal amounts. UK operator pages list the RTP at up to 97.30%. Our Lightning Roulette page explains the trade-off.
