The numbers you see beside a snooker player’s name are not a forecast and not a tipster’s view. They are a price, set by a bookmaker, with a margin already taken out. Reading snooker odds well means seeing that margin, the limits around it, and the markets that sit behind it.

Why Responsible Gambling Comes Before Any Odds Page

Snooker tournaments run almost year-round, the season stretches from late spring through to the World Championship in early May, and a punter who watches every televised frame has more matches available than a casual follower realises. Volume is the first thing that makes a snooker odds page worth reading carefully. A sport you can bet on daily, on markets that run from outright tournament winner down to the colour of the next ball potted, can move money out of a bankroll faster than a sport that only matters a few Saturdays a year. Current as of 27 October 2026. Checked against the Gambling Commission’s public register of remote betting licences.

That is why responsible gambling tools exist, and why they have to be named before a price. Every brand on the Gambling Commission’s public register binds itself to the national self-exclusion scheme GAMSTOP, which lets a customer bar themselves from every licensed online bookmaker and a betting app for six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. Online sites and apps are covered by GAMSTOP; betting shops use a separate service.

Alongside GAMSTOP, each licensed remote operator must offer timeouts, deposit limits and reality checks under the Commission’s social responsibility code. The headline rule that lands in this financial year is the financial vulnerability check, which applies when a customer’s deposits minus withdrawals cross £150 in a rolling 30-day window: the operator runs a public-record check (bankruptcy, county court judgments), not an income check and not a credit-reference check. Further affordability work has been announced by the Commission on 7 July 2026, with a phased timetable and no start date for the heavier assessments, so any page that promises “instant large withdrawals” without a check is not describing a licensed operator. State plainly that the check exists, that it is rolling, and that the threshold is £150 over 30 days.

If gambling stops being fun, the named routes are GamCare (which runs the National Gambling Helpline), GambleAware, the NHS gambling clinics network, and Gamblers Anonymous. A licensed brand carries these links from its safer-gambling page; a snooker price on an unlicensed site carries none of them.

Crypto, Crypto Sites and the Loss of a Licence

A handful of searchers for snooker odds arrive by way of “crypto snooker betting”, “snooker betting with bitcoin” and the related terms. The honest answer is short: at a Gambling Commission-licensed remote bookmaker there is no anonymous play. Identity is verified before the first deposit or gamble (since 7 May 2019), credit cards have been banned for gambling in Great Britain since 14 April 2020 (including credit-card-funded e-wallet top-ups), and source-of-funds questions at higher spend are normal under the money-laundering rules.

That means a snooker bettor who wants to deposit in bitcoin, ethereum or any other coin has to step outside the licensed market. Operators licensed in Curaçao, in certain Caribbean jurisdictions, or under looser regimes will take crypto and may take it without checking one. What that punt gives up is the entire British safety net. There is no GAMSTOP cover, no Commission complaints route, no approved dispute-resolution body, and no British consumer redress if funds are withheld. The 10x bonus wagering cap, the £150 vulnerability check, the LCCP marketing rules, all the safer-gambling duties a UK-licensed brand takes on, do not apply offshore. The Commission’s enforcement against unlicensed sites is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars and payment providers, and new court-order DNS blocking powers that have been given, or are about to be given, to the regulator. None of that means a customer has committed an offence by betting on such a site; what it does mean is that if a brand refuses to pay out, the only recourse is the operator’s own house rules.

For most readers the trade is not worth making. Snooker markets at a licensed British bookmaker cover the World Championship, the UK Championship, the Masters, the Champion of Champions, the Scottish Open, the English Open, the Shanghai Masters and most ranking tournaments; outright, match, frame, handicap, total frames, first-ball-pot and century-break markets run throughout the calendar. A crypto route does not unlock a market the licensed shops do not already price. What it gives up is real.

Snooker Betting Offers, Free Bets and What the Marketing Word Really Costs

The phrases “free bet”, “bet £20 get £40” and “100% bonus” travel across football, horse racing and snooker alike, and on every sport they mean the same thing: a promotional credit whose stake is rarely paid back with a win, whose value depends on the price you take it at, and whose headline number describes the maximum, not the typical, return. Two recent offers from the licensed set show what the wording looks like on a snooker page.

Coral’s sports welcome offer is the “Get £40 in Free Bets when you bet £20” shape: deposit and place a sports bet of £20 or more at minimum odds of 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue, for new GB customers who opt in. Unibet’s UK offer shares the same qualifying terms, with free bets expiring within 7 days of issue, for new GB customers using a debit card or instant bank transfer. BetMGM’s sports welcome offer for new UK customers who deposit £10 or more and place a sports bet within 7 days is four £10 free bets: two football accumulators of four or more selections and two sports multiples of two or more selections, with minimum odds, an opt-in and a 7-day validity. VBet’s sports welcome offer is a £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses.

The free-bet value is what matters once the headline is stripped off. The Commission’s promotion rules, in force since 19 January 2026, cap wagering requirements on bonuses at 10x — a £10 bonus at 50x needing £500 of bets; under the cap, no more than £100. Mixed-product promotions, an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery, are banned at licensed brands. Whether the cap applies to free bets with no wagering condition is not established, and neither is any cap on the money value of a bonus, so treat each free-bet headline as a maximum: a £10 free bet whose stake is not paid back, taken at odds of 3.00, pays £20 on a win, of which the bookmaker’s margin at a typical snooker market can take a meaningful slice before the stake converts to withdrawable cash.

For snooker specifically, the search for “snooker world championship free bets” peaks around the Crucible fortnight in April and May, which is also when the bookmakers push their strongest price boosts, accumulator insurances and tournament specials. The 2026 World Snooker Championship ran from 18 April to 4 May 2026 at the Crucible Theatre, and Wu Yize beat Shaun Murphy 18-17 in the final, with the winner receiving £500,000 from a £2,395,000 prize fund. The price the champion was at the start of that tournament, and the price of every other match winner through the early rounds, is exactly the kind of offer a bookmaker boosts to grab the season’s attention. Read it as a marketing event, not a tip.

Live Snooker Betting and the Question of Cash Out

Live snooker betting, also called in-play, lets a punter back a player frame by frame through a match, lay a player on a betting exchange as their lead grows, or back the next frame when a player has just missed a frame-ball black. The markets at a licensed bookmaker typically cover match winner, next frame, total frames in the match, next century break, next 50+ break, the colour of the next ball potted, and the result of the frame after a missed red. In-play snooker odds move with the score and the balls on the table; a player 5-3 up with the balls at his mercy will be a short price to win the match, and a price into the next frame shifts the moment a long red splits the colours.

Cash Out is the tool that sits beside live betting, and it lets a customer settle a bet before the final frame for a value the bookmaker offers. The offered value is the bookmaker’s valuation of the position, not the true price, and on a long match the gap between the two widens as momentum shifts. 888sport’s app shows the live bet feed, a bet builder, daily boosted odds, racing streams and Cash Out, and that combination is the typical one across the licensed set: pre-match and in-play markets, a bet builder for snooker frame handicaps, Cash Out, and a live bet feed that updates prices between frames. Some licensed brands also offer streaming of selected snooker events through their in-play pages, particularly during the World Championship and the UK Championship.

The deeper point is the one that always sits behind a live-bet menu. In-play betting is offered by GB bookmakers under the operator’s own licence conditions and customer-protection duties, and the controls the Commission enforces are about customer protection, not about restricting in-play itself. The Commission’s view is that in-play is a normal part of the licensed product; what is restricted is the marketing, the messaging to under-25s, and the bonus rules around it. A live-bet menu is a marketing line on the brand’s page; the safer-gambling tools it sits between are the regulator’s requirement. Read both.

Snooker Betting Tips, Predictions and What a Tip Actually Is

Searches for “snooker betting tips”, “snooker betting today” and “snooker betting predictions” pull in a steady audience around every ranking event. The honest framing is short. A tip is a view; a price is a market view. The two move together only when the price lags the view, which is hard to know after the event and impossible to know before it.

The shape of a useful prediction page is a process, not a tipster. Look at the head-to-head across the season, at the form over the last six ranking events, at the venue (the Crucible, the York Barbican, the Alexandra Palace, the Ricoh Arena), at the frame format (most professional matches are best of 7, 9 or 11 frames, with the World Championship ranging from best of 19 in the first round to best of 35 in the final), at the century-break count a player has compiled this season, and at the tactical match-up (a heavy scorer against a safety-first grinder, a break-builder against a long-pot specialist). None of that tells you who wins the next frame. It tells you the price at which backing a player stops being a coin-flip and starts being a value bet, which is a different question.

The price-versus-tip distinction matters because every snooker price carries the bookmaker’s margin. A match between two players of equal ability, priced at 1.91 / 1.91, pays less than the obvious book suggests. That is what the next section is about: not who wins, but what the price is built from.

Snooker Bet Types, Odds Formats and Where the Margin Hides

A snooker price is read in two forms across Great Britain: fractional (5/1, 11/4, evens) and decimal (6.00, 3.75, 2.00). Fractional is the older British bookmaker form, where 5/1 means £5 of winnings for every £1 staked and the total return is £6; decimal expresses the total return, where 6.00 means every £1 staked returns £6. Converting fractional a/b to decimal is a÷b + 1: 5/1 → 5÷1+1 = 6.00; 11/4 → 11÷4+1 = 2.75+1 = 3.75; evens (1/1) → 1.00+1.00 = 2.00. The same price in two notations, with the same winnings, just told differently.

A single is one selection; a double two, a treble three, and an accumulator (“acca”) four or more, with the odds of the legs multiplied into one price. A combination bet is only as safe as its weakest leg. A frame handicap, a total-frames market and an outright tournament winner all price differently, because each has a different number of outcomes and a different margin. The first leg of a World Championship outright is essentially a futures market, with hundreds of runners, and the margin on an outright can run higher than the margin on a single match.

The margin is what the bookmaker keeps of every unit bet on a market. For a two-way market with decimal odds 1.90 / 1.90 (the example the spec routes through this page), the implied probabilities are 1÷1.90 and 1÷1.90, which sum to 1.0526. The bookmaker pays out the inverse of the sum, around 0.95 per £1, and keeps the rest, around 0.05 per £1, as margin. That 5% is what every price already contains before the event starts: a tenner on the player at 1.90 returns £19 on a win, of which the bookmaker keeps roughly 50p as their edge, and the rest is your net of a £9 profit on a £10 stake.

A “price boost” or “enhanced odds” headline moves the decimal odds in your favour at a single bookmaker for a specific event. A boosted 1.90 to 5.00 on the winner of a televised first-round match can look generous, but the boost applies to that single bet, the maximum stake is usually small, and the free-bet winnings, when the boost is part of a free-bet offer, are paid as bonus credit rather than cash. Read the boost the way you read the headline.

Two standard markets need their own word. An each-way bet is two bets of equal stake, the first on the player to win and the second on the player to place (top half, top quarter, or top third depending on the field); the stake doubles. Each-way is mostly a horse-racing construct, but it does appear in outright tournament markets at some snooker bookmakers, and the place terms vary by race, tournament and operator. A betting exchange, run under a remote betting intermediary licence, lets a customer back a player at one price or lay a player at another, with the exchange taking a small commission on net winnings; the price on the exchange is built by punters rather than by a bookmaker, and it carries a different margin, often thinner at the head of the market.

Snooker, the Calendar and the Tournaments Worth Naming

Snooker is played with 22 balls: a white cue ball, 15 reds and six colours worth yellow 2, green 3, brown 4, blue 5, pink 6 and black 7. A maximum break is 147, made by potting all 15 reds with blacks and then all six colours. A full-size table is 12 ft by 6 ft with six pockets. Most professional matches are best of 7, 9 or 11 frames, with the major championships extending deeper into the schedule. The World Snooker Championship has been at the Crucible Theatre in Sheffield since 1977, with the men’s event ranging from best of 19 frames in the first round to best of 35 in the final, and the women’s and seniors’ championships running alongside it in the spring. The game is governed by the World Professional Billiards and Snooker Association (WPBSA), which owns the official rules, while the International Billiards and Snooker Federation (IBSF) governs amateur competition.

The professional record books still have two names at the top of the modern era. Stephen Hendry and Ronnie O’Sullivan have seven world championships each in the modern era; Joe Davis won 15 in a row from 1927 to 1946, a record that has not been approached under the modern rules. The 2026 World Snooker Championship, the tournament’s 50th staging at the Crucible, was won by Wu Yize, who beat Shaun Murphy 18-17 in a final that went to the last frame; the prize for the winner was £500,000 from a £2,395,000 prize fund. Outside the Crucible fortnight the calendar runs through the UK Championship in November and December (York Barbican since 2011), the Masters in January (Alexandra Palace since 2012), the Champion of Champions in November, the Players Championship and the Tour Championship in the spring, and the ranking events at the Ricoh Arena, the Morningside Arena, the Barnsley Metrodome and a handful of Asian venues. Outright markets open months before a ranking event; match markets open days before; frame-by-frame markets open at the first ball of the match.

For betting purposes the calendar matters because the depth of the market follows the calendar. The World Championship, the UK Championship and the Masters carry outright, match, frame, handicap, total-frames, first-ball, century-break and session markets at every licensed bookmaker; the lower-tier ranking events carry outright and match markets with thinner frame coverage. The Masters and the Champion of Champions are invitational, which compresses the field and sharpens the price. The Crucible fortnight, with its long format and its late-night finishes, is where cash out and in-play liquidity are deepest.

Ten Licensed Bookmakers and How They Compare on Snooker

The ten brands below each hold a Gambling Commission remote licence for real-event betting, and each is described only as its own terms state it. The order below is not a ranking of how good any one is at snooker: it is the order in which the licences were registered against these brands. The comparison that follows each name is the platform’s own statement of what it offers; the judgement of what it is worth to a snooker punter sits at the end of each write-up.

Every brand in the table above is on the Gambling Commission’s public register against a remote betting licence for real events. The Commission’s register is searchable by business name, trading name, domain or account number, and the account numbers are the way to verify a licence directly. The holder of a remote licence is not always the same company as the operator of the trading brand — Ladbrokes and Coral run under LC International Limited, Paddy Power and Betfair share a parent — and the table above names the licence holder as the register states it, never as a description of who runs the brand day to day.

BetMGM

BetMGM’s UK licence sits under LeoVegas Gaming PLC, with the Gambling Commission account number 39198, which holds the brand’s remote general betting licence for real events. The brand’s welcome offer is structured around four £10 tokens (two football accumulators of 4+ and two sports multiples of 2+), each with its own 7-day clock, each subject to minimum odds and an opt-in. For a snooker punter the relevant point is that the £40 of free bets does not have to be spent on football; the football tags are the default split, and the brand’s own terms state the four bets as football accumulators and sports multiples, not as snooker-specific credits. Treat the welcome as a generic sports credit, and pick your snooker markets at prices that justify the free-bet value rather than at the boosted prices the offer page highlights.

Bar One Racing

Bar One Racing, now trading as BAR 1 Betting, is an Irish independent bookmaker with shops across Ireland and sponsorship deals at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork. The licence sits under Bar-One Racing Limited on the Commission’s register, account 56516, which authorizes remote general betting on real events. The brand’s published profile leans on horse racing and Irish sport; its snooker coverage sits inside its general sports menu rather than as a featured sport. For a snooker punter with an existing BAR 1 account the convenience is the Irish shop tie-in and the SP on Irish racing; for a snooker-only reader, the snooker menu is worth checking before staking because the depth of frame and total-frames markets varies by event.

QuinnBet

QuinnBet’s licence sits under QuinnBet (Gibraltar) Limited on the Commission’s register, account 61011, for remote general betting on real events. The brand’s headline promotion is Best Odds Guaranteed on Irish and UK horse racing from 10:00am daily, on singles, multiples and system bets, with a maximum benefit of £150 per customer per race. Snooker sits inside the sports menu without the BOG tag; what the snooker punter gets is the same operator-level experience (debiting, withdrawal speed, in-play availability) but without the price-floor on racing. Read the welcome offer carefully: BOG does not extend to snooker, so the snooker price is whatever the menu shows at the moment of staking.

Coral

Coral’s licence sits under LC International Limited, with the Commission’s account 54743 covering both remote general betting on real events and the remote betting intermediary category (the licence for betting exchanges). The £40-in-free-bets welcome, the same shape Unibet runs, is the standard “bet £20 at minimum odds 2.0” form: deposit and stake £20, receive £40 in free bets within 7 days, expire 7 days after issue, opt-in required. For a snooker punter the relevant detail is the minimum-odds floor, which lifts the qualifying bet out of the longest-priced outrights and into the match-winner or frame-handicap range; the free bets themselves can be spent on snooker, which is the point. Coral has run snooker promos around the World Championship and the UK Championship in recent seasons, and the menu at the time of the tournament is the place to check the offer shape.

Smarkets

Smarkets is the exchange entry on the Commission’s register, account 39173 under Smarkets (Malta) Limited, running on a remote betting intermediary licence rather than the standard remote general betting licence. The platform’s own terms on payments are the cleanest of the set: UK deposits by open bank transfer are instant from £10 to £10,000, withdrawals processed within 6 hours from £10 to £100,000, and UK debit card deposits are instant from £10 to £15,000. For a snooker punter the value is twofold: the lay side of the market, where you can take the position that a player will lose, and the thinner margin on the back side, set by punters rather than by a single bookmaker’s trading desk. The drawback is depth: liquidity on a first-round ranking event can be light, and the price you want is sometimes the price that does not get taken.

VBet

VBet’s licence sits under SCGO Limited on the Commission’s register, account 44662, covering remote general betting on real events. The welcome offer is the simplest of the set: a £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses. The free bet is paid as a free bet, with the stake not returned on a win, and the 7-day expiry and minimum-odds terms apply. For a snooker punter the value is in keeping the qualifying bet at a price where a loss is plausible and a win is acceptable: a price-boosted player in a televised first-round match fits the shape, and the free bet pays whatever the menu shows on the chosen match.

Unibet

Unibet’s UK licence sits under Platinum Gaming Limited, Gibraltar, with the Commission’s account 45322 under the brand’s remote general betting licence for real events; the brand states it has operated since 1999. The UK sports welcome offer is the same shape Coral runs: “Get £40 in Free Bets when you bet £20” — a deposit and sports bet of £20 or more at minimum odds 2.0 (1/1), free bets expiring within 7 days, for new GB customers using a debit card or instant bank transfer. The snooker menu has carried outright, match and frame markets across the ranking events for several seasons, and the in-play coverage on selected televised matches is the place to check before a session. For a snooker punter, Unibet is one of the safer places to spend a free-bet credit because the menu depth survives the World Championship lull.

888sport

888sport’s licence sits under 888 UK Limited, with the Commission’s account 39028 authorized for remote general betting on real events. The brand’s published feature set is the broadest of the comparison: pre-match and in-play betting, Cash Out, Bet Builder, racing streams, BetFinder form tools, a live bet feed and daily boosted odds. For a snooker punter the Bet Builder is the standout, because a snooker frame bet builder lets a customer combine match winner, total frames, first century break and next colour potted into one accumulator; the cash-out feed lets the customer close the bet between frames. Read the boosted-odds headline the way every boosted-odds headline reads: a marketing line, with a maximum stake that varies by offer.

Tote

Tote’s licence sits under TDCO Limited on the Commission’s register, account 54779, which holds the brand’s remote general betting licence for real events. The brand’s heritage is pool betting on British and Irish racing, with fixed-odds sports added more recently. The Tote’s snooker menu is part of the sportsbook rather than a featured category, and the brand’s snooker-specific terms are best checked on the operator’s own page before staking a bet. For a snooker punter with a Tote account, the value sits in the familiar interface and the racing-side promotions; for a snooker-only reader, the menu is worth checking but not worth opening an account for alone.

Kwiff

Kwiff’s licence sits under Eaton Gate Gaming Limited on the Commission’s register, account 44448, for the brand’s general betting licence (real events). Its app carries a 17+ age rating in the App Store, which is the standard rating for a UK gambling app; the trademark is operated by Spryme Ltd. Kwiff’s distinctive mechanic is a randomised odds enhancement on selected markets, where a customer’s price on a chosen bet can be “supercharged” to a higher figure. For a snooker punter the value is in the menu coverage on televised events and in the chance of a supercharge on a selected frame or match bet; the drawback is that the supercharge is a randomised feature rather than a stable price, and a punt at a normal price is what the punter actually has when the randomiser does not fire.

Where Snooker Betting Sits Inside British Gambling Law

Snooker betting in Great Britain sits inside the same regulatory frame as betting on any other sport. The Gambling Act 2005 covers Great Britain (England, Scotland and Wales); Northern Ireland is outside the Act and runs under older law, so a Great Britain licence regulates the GB market only, and a Northern Ireland customer should check the operator’s terms before staking. The regulator is the Gambling Commission (UKGC), a non-departmental public body sponsored by the Department for Culture, Media and Sport.

Since the Gambling (Licensing and Advertising) Act 2014, an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based (sections 33 and 36 of the 2005 Act as amended). A Curaçao, Maltese or Gibraltar licence is not a substitute for a GB licence at the point of consumption. There is no state monopoly, no statutory list of permitted sports or markets, and no cap on the number of licences. The Commission’s public register is the whole test of whether a brand holds a licence; quote no count without its access date.

The licence categories that matter for snooker are remote general betting standard (real events), which covers outright, match, frame and total-frames markets on actual tournaments; remote betting intermediary, which covers betting exchanges; remote general betting standard (virtual events), which covers computer-generated events and is a separate category; and pool betting, which is a separate licence. Snooker sits inside “real events” rather than “virtual events”, and an operator licensed only for virtual events cannot offer real snooker markets.

Minimum age 18. Identity is verified before the first deposit or gamble, including with a free bet or bonus, which is why the licensed market is not anonymous. The financial vulnerability check at £150 of deposits minus withdrawals over a rolling 30 days runs a public-record check (bankruptcy, county court judgments), not an income check and not a credit-reference check; the broader affordability assessment has been announced with a phased timetable and no start date.

Advertising runs through the CAP Code (Committee of Advertising Practice, non-broadcast) and the BCAP Code (Broadcast Committee of Advertising Practice, broadcast), enforced by the ASA alongside the Commission’s LCCP marketing rules. The “whistle-to-whistle” rule, since 1 August 2019, prevents betting ads on TV from five minutes before a live sporting event to five minutes after, before the 9pm watershed; horse and greyhound racing are excluded. The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts from the 2026/27 season is voluntary, not law, and sleeves and hoardings remain.

The player pays no tax on betting winnings in Great Britain (general information, not tax advice). General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Spread betting has its own rates (3% financial, 10% other). Whether operators pass duty on through odds is not established, and the player’s take-home does not change.

Frequently Asked Questions About Snooker Betting Odds

How do you bet on snooker?

Pick a licensed bookmaker that holds a Gambling Commission remote licence for real-event betting, complete identity verification (name, address, date of birth), and open an account with a payment method that is not a credit card. Choose a snooker market — outright tournament winner, match winner, frame handicap, total frames, first century break, first colour potted — and add a selection to the bet slip. Enter a stake within the operator’s minimum and maximum, confirm the bet, and watch the match. Settling happens after the official result.

Can you bet on snooker in Great Britain?

Yes. Snooker is a real sporting event covered by the “remote general betting standard (real events)” licence category, and every bookmaker in this comparison holds a remote licence that includes it. There is no statutory list of permitted sports and no ban on snooker betting in Great Britain; the only rule is that the operator must hold the relevant Commission licence and the bettor must be 18 or older and verified.

How can a reader check that a bookmaker holds a Gambling Commission licence?

Open the Commission’s public register, search by business name, trading name, domain or account number, and confirm that the licence category includes remote general betting standard (real events) for sports betting, or remote betting intermediary for an exchange. The register entry also names the licence holder, which is not always the same company as the trading brand. Quote no count of licensed operators without its access date.

How is the return on a bet worked out from the stake and the odds?

In decimal odds, return equals stake multiplied by the odds: a £10 stake at odds 3.00 returns £30, of which £20 is profit and £10 is the stake returned. In fractional odds, profit equals stake multiplied by the fraction and the stake is returned on top: a £10 stake at 5/1 returns £60, of which £50 is profit and £10 is the stake returned. For a combination bet, the odds of the legs multiply into one price before the stake is applied.

What is the bookmaker’s margin and how does it sit in the odds?

The margin is the share of every unit bet that the bookmaker keeps on a market. For a two-way market with decimal odds 1.90 / 1.90 (the example this page works through), the implied probabilities are 1÷1.90 and 1÷1.90, summing to 1.0526; the bookmaker pays out around 0.95 per £1 and keeps around 0.05 per £1, which is a margin of roughly 5%. As a band, expect a margin between roughly 4% and 8% on a snooker match-winner market at a licensed bookmaker, with the figure varying by event, by market and by how close to the off the price is taken. A larger margin is not a tip against the bettor; it is the price of running a deep market with a regulated safer-gambling infrastructure behind it.

How do fractional odds such as 5/1 convert to decimal odds such as 6.00?

Fractional odds a/b convert to decimal by a÷b + 1. 5/1 is 5÷1 + 1 = 6.00; 11/4 is 11÷4 + 1 = 2.75 + 1 = 3.75; evens (1/1) is 1÷1 + 1 = 2.00. The two notations describe the same price, with fractional odds showing profit only and decimal odds showing total return. The bookmaker’s margin, the stake, the win and the loss all read the same way once the conversion is done.
