In the conventional model, a straight-up number pays 35:1 profit, returning £36 from a winning £1 stake. Its chance is 1/37 on a fair single-zero wheel or 1/38 on a fair double-zero wheel. Other wagers cover more pockets and pay less. Special paytables, the five-number basket and zero-return rules need separate treatment. ![A conventional one-pound straight-up roulette wager returns thirty-six pounds on a win, while its winning chance is one in thirty-seven on single zero and one in thirty-eight on double zero.](https://howtocasino.uk/illustrations/roulette-odds-reference.png) Fair equal-pocket models, conventional 35:1 profit price, no multipliers or special rules. £36 total return includes the winning £1 stake; it is not £36 profit. ## What is the difference between winning probability and payout odds? Winning probability counts the results covered. Profit odds describe the amount won for each unit staked when the bet wins. Neither tells you the other without the actual wheel and payout rules. | Term | Conventional single-number example | | --- | --- | | Winning probability on single zero | 1/37, about 2.70% | | True odds against winning | 36 losing pockets to 1 winning pocket: 36:1 | | Profit payout | 35:1 | | Total return from a winning £1 | £35 profit plus £1 stake: £36 | The true odds against a win and the offered profit price differ. On double zero, that specified number instead faces 37 losing pockets, so the true odds against it are 37:1 while the conventional profit price stays 35:1. A price printed on the layout is not a probability estimate.

Assume equally likely pockets, one separate £1 wager, conventional profit prices and no multiplier, side feature or special zero settlement. For probability, single zero has 37 pockets and double zero has 38. Percentages are rounded. | Wager | Pockets covered | Profit odds | Winning £1 total return | Single-zero chance | Double-zero chance | | --- | --- | --- | --- | --- | --- | | Straight-up | 1 | 35:1 | £36 | 1/37 ≈ 2.70% | 1/38 ≈ 2.63% | | Split | 2 | 17:1 | £18 | 2/37 ≈ 5.41% | 2/38 ≈ 5.26% | | Street / qualifying trio | 3 | 11:1 | £12 | 3/37 ≈ 8.11% | 3/38 ≈ 7.89% | | Corner | 4 | 8:1 | £9 | 4/37 ≈ 10.81% | 4/38 ≈ 10.53% | | Six-line | 6 | 5:1 | £6 | 6/37 ≈ 16.22% | 6/38 ≈ 15.79% | | Dozen / column | 12 | 2:1 | £3 | 12/37 ≈ 32.43% | 12/38 ≈ 31.58% | | Red/black, odd/even, low/high | 18 | 1:1 | £2 | 18/37 ≈ 48.65% | 18/38 ≈ 47.37% | Read the actual layout to establish whether a particular split or zero-area group is offered and which numbers it covers. The chart does not make every arbitrary group of two, three or four numbers a valid wager.

A losing wager returns £0 in the stated full-loss model. For an entire round, add the returns from all wagers and subtract all money committed. | Example winning wager | Profit | Total return | | --- | --- | --- | | £2 on red at 1:1 | £2 | £4 | | £2.50 on one number at 35:1 | £87.50 | £90 | | 50p on a dozen at 2:1 | £1 | £1.50 | If your display already reports the complete amount returned, do not add the winning stake again. A 36× total-return multiplier and 35:1 profit describe the same conventional straight-up settlement only if the stated units match. A winning component is not necessarily a profitable whole round. Other wagers may have lost. The [beginner guide](https://howtocasino.uk/guides/how-to-play-roulette/index.md) includes a two-wager ledger; the [bet-types guide](https://howtocasino.uk/guides/inside-and-outside-roulette-bets/index.md) shows a multi-chip package with unequal payouts across its covered numbers.

A straight-up wager on either pays 35:1 profit, just like another individual number. Double zero does not mean double the prize, and a bet on 0 does not also cover 00. Ordinary red/black, odd/even and high/low groups exclude the zero pockets. A fair single-zero red wager therefore wins on 18 pockets and loses on 19 under full-loss zero rules. That is why an even-money profit price does not make its winning chance exactly one half. The [zero-wheel comparison](https://howtocasino.uk/guides/single-zero-vs-double-zero-roulette/index.md) explains the conventional 2.70% and 5.26% house-edge models. Those values describe specified prices and outcomes, not a fixed loss that every short session must produce.

Its winning probability is 5/38, about 13.16%, and a winning £1 returns £7. The expected total return is 5 × £7 / 38 = £35/38, leaving an expected loss of £3/38 per £1, about 7.89%. It is not the ordinary 5.26% double-zero edge. Where La Partage applies to an eligible single-zero even-money wager, a zero returns half the stake instead of losing it all. It does not change the probability of red, increase the red profit price or automatically apply to dozens and columns. En Prison holds an eligible wager for later resolution under its own rules. Multiplier and other modified games can change ordinary prices. A familiar wheel or French label does not establish the complete paytable. Check the actual qualifying wagers, feature costs and settlement rules before importing this chart.

It can miss many times or appear more than once close together; the denominator is not a schedule. For an explicitly mathematical example, the chance of at least one hit on the same selected number in ten such spins is 1 − (36/37) to the power 10, about 23.97%. It is not 10/37: simply adding probabilities would double-count sequences containing more than one hit. This counts hits under the stated model. It is not a guarantee, a reconstruction of an unknown table or a cash-flow forecast for changing stakes and other wagers. A previous sequence does not remove the need to state the assumptions. ## What should you check before using any roulette odds table? 1. Count the actual pocket outcomes and identify the exact wager’s covered numbers. 2. Establish whether the price means profit or the complete return. 3. Check special zero rules, multipliers, side features and any additional cost. 4. Add every accepted wager before calculating a whole-round net result. 5. Use the published rules for a disputed round rather than a generic chart from another variant. Our [roulette-fairness guide](https://howtocasino.uk/guides/is-online-roulette-rigged/index.md) explains what evidence can and cannot show about an implementation. A correct probability calculation does not itself audit a wheel or guarantee compliance by a website.

The actual variant can use a modified paytable, so check its rules.

Checked 2026-10-29. ### Does double zero pay more than zero? Not in the cited conventional double-zero model. A straight-up wager on either 0 or 00 pays 35:1 profit; they are separate pockets and separate selections.

Checked 2026-10-29. ### Are the true odds of a single-zero number 35:1? The true odds against that number are 36:1 under equal-pocket assumptions, because 36 pockets lose and one wins. The offered conventional profit price is 35:1; price and probability are different quantities. ### Is red or black a 50/50 roulette wager? Not with zero pockets included. A conventional single-zero red wager covers 18 of 37 pockets; on double zero it covers 18 of 38. Its 1:1 profit price does not change those counts.

Dozens, columns and straight-up numbers do not automatically inherit it.

A repeated-spin calculation must state its independence and game-model assumptions. ## Sources and checks - [Roulette rules: international payout model, not GB availability](https://www.pokerstars.com/casino/how-to-play/roulette/rules/) — PokerStars international.
