Curling opens its season in autumn and runs through to the World Championships in spring, with the Winter Olympics every four years on top. Most weeks of the calendar there is something to bet on, and most GB-licensed bookmakers carry the sport at least in passing. What is harder to find, in plain English, is what all of that costs the reader. This guide is built around that question: where the law sits, what the tournaments actually look like, which bookmakers take curling markets seriously, how an odds margin and a bonus turn into a number the bettor pays, and where a GB licence actually bites into the offer.

The data on this page is current as of 27 October 2026 and was checked against the Gambling Commission’s public register and each operator’s own terms.

The licence on the wall: the rule book under which any of this happens

Every online bet a person in Great Britain places with an operator sitting outside the country runs under one statute, the Gambling Act 2005, and one regulator, the Gambling Commission. The 2014 Gambling (Licensing and Advertising) Act closed the old offshore loophole: a remote operator needs a Commission licence wherever it is based if its products are used in Great Britain. A Curaçao, Malta or Gibraltar licence does not stand in its place, however common those seals look on a website footer. There is no approved alternative regulator for GB customers, no grandfathered arrangement, and no minimum threshold below which the rule stops applying.

The Commission’s public register is searchable by business name, trading name, account number or domain, and it is the whole test of who holds a licence. Every brand reviewed later in this guide appears on that register with an entry that names the licensee, the trading name, the categories of licence held and the dates it covers. The register is open to anyone, free to use, and the access date is the only thing that ages. The set of GB-licensed brands is wider than any shortlist can show: a register entry is not a ranking and never a recommendation, and an operator’s absence from a comparison is not evidence that it is unlicensed.

The categories on the register matter for what an operator is allowed to take bets on. A remote general betting standard (real events) licence covers fixed-odds sports betting at the level a curling punter would recognise; a remote general betting standard (virtual events) licence covers simulated events; remote pool betting is its own category for horse and dog racing pools; a remote betting intermediary licence covers betting exchanges; a remote general betting limited licence is a narrower permission. Several well-known brands run under one licence, so the same corporate entity can power more than one trading name. Treating each name as independent misreads the register.

The Act covers Great Britain — England, Scotland and Wales. Northern Ireland is outside the 2005 Act and is governed by older law, so a “GB licence” describes what a Commission entry actually means and stops short of claiming jurisdiction in Belfast.

Minimum age is 18. Identity is checked before the first deposit or bet, including with a free bet or bonus, and that includes a credit, fraud and identity check against public records; this has been in force since 7 May 2019 and it is one of the sharper edges of a Commission licence. Anyone planning to delay sign-up until a final is in play should know that the verification step runs every time, on the casino side and on the betting side alike. The Commission’s customer verification is not a marketing line; the price of a GB licence is sitting on the other side of it.

Credit cards are banned for gambling in Great Britain, including the indirect route through an e-wallet funded by a credit card, since 14 April 2020. Debit cards and bank payments, including instant bank transfer, are not caught by that rule. No statutory list of permitted payment methods or named-account rule has been published; what methods an operator accepts, and any minimum deposit, is found in the operator’s own payments page.

One thing the statute does not do is name a permitted-sport list or a permitted-market list. There is no Commission document saying “you may offer curling” or “you may offer in-play curling” — the categories above describe what the licensee may do, not which sport it covers, and which markets appear under each sport is a question for the operator and the Licence Conditions and Codes of Practice. Anyone asking whether it is legal to bet on curling is really asking whether the operator they are using holds a valid licence; the second question is answerable in two minutes on the public register.

Where the rule book actually pays a return

Three rules that read like compliance boilerplate change what lands in a betting account.

The first is the bonus cap. Since 19 January 2026, wagering requirements on a bonus are capped at 10x: a £10 bonus at the cap needs £100 of qualifying bets to clear; under the cap no more than that. The same ruleset bans mixed-product promotions — an offer that requires a bet to unlock casino free spins, or vice versa. A bookmaker can still hand out a free bet; what it cannot do is attach an unrealistic clearing multiplier to it. That is the kind of reading a reader does once and saves money on for years.

The second is the vulnerability check. Where a customer’s deposits minus withdrawals cross £150 in a rolling 30 days, a financial vulnerability check fires: a public-record check (bankruptcy, county court judgments), not a payslip request. The check has applied since 28 February 2025 under LCCP condition 3.4.4 in force since 30 August 2024. Affordable gambling is being regulated, not legislated, and it now reaches into every active account with any sort of regular flow. Financial risk assessments — the heavier affordability checks — are announced in a staged plan, no start date published; write them as “announced, staged, no start date”.

The third is the duty change. 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 General Betting Duty, while remote bets on UK horse racing, betting-terminal bets, pool betting and in-person betting remain at 15% (HM Government policy paper of 26 November 2025). Until that date the remote rate stays at 15%. Whether operators pass duty on through odds, or absorb it, is not established; never write that the player pays duty, because the player does not. The change matters all the same, because it puts pressure on the margin a remote operator can hold; over a season that pressure lands somewhere.

Players pay no tax on betting winnings in Great Britain. That is general information, not tax advice; a professional gambler’s situation is different and HMRC or a tax adviser is the right next call.

Where the safety net sits: what a GB licence gives the punter

A GB licence is more than a stamp. Five things it actually changes, all of them visible on a betting slip in some form.

GAMSTOP is the national multi-operator self-exclusion scheme, mandatory for every GB-licensed online operator since 31 March 2020. A single registration excludes a customer from every site and app that is part of the scheme, and the periods run six months, one year, five years or five years auto-renewing. After the minimum period the exclusion carries on for a further seven years unless GAMSTOP is asked to remove it. Betting shops use a separate scheme. There is no opt-out, no “excluded everywhere except”, and the exclusion begins the moment the registration is confirmed. That is what a GB licence buys.

Deposit limits are a separate matter: an operator must offer a gross deposit limit on a fixed time frame, but no state-set ceiling exists. The numbers are the customer’s choice. What the operator cannot do is the reverse, which is to drop a limit below zero or to make changes only in one direction. New rules entered the first phase on 31 October 2025; a second phase was postponed to 30 September 2026, and whether it is now in force is not established. The reader’s practical question is simpler: every licensed site has a deposit-limits panel, and the panel is the lever to pull.

Customer support and dispute resolution sit with the operator in the first instance, and with approved dispute-resolution bodies on appeal. The Commission’s complaints route is for matters the ADR cannot resolve. A reader who keeps records of deposits, withdrawals, bet timestamps and the bet reference has the cleanest path through any later dispute.

Help exists outside the operator, too. GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs meetings. None of these is a substitute for self-exclusion; they sit alongside it. The choice to use any of them is itself a lever that costs nothing to pull, and the cost of not knowing the names is far higher than the cost of knowing them.

Self-exclusion and the responsible-gambling controls on a licensed site are not theatre. They are conditions of the licence itself, and removing them — or making them hard to find on the site — is a breach that the Commission has the power to act on.

Where the licensed route costs the reader

Two trade-offs come with the licence, and any honest guide says them out loud.

The first is verification. A licensed site wants a name, a date of birth, an address and a payment method before the first deposit, and the want turns into a hard requirement at the first attempt to play. That removes the possibility of betting anonymously, including with a free bet or bonus. Anyone who preferred the old “open a tab, deposit later” model is paying for the new rule in convenience.

The second is the duty change. The 15% rate moves to a 25% remote rate on 1 April 2027. Whether the price the reader sees changes before or after that date is an operator decision; nobody is passing duty on to the player in a way that shows on the slip, because the bookmaker cannot legally do so. What is more likely is that a 25% cost base shows up, eventually, in the margin of a market on the more contested sports. Curling is small enough that the impact may not show at all, but the operator’s overall margin is the pressure point the duty applies to.

The offshore side of the line, in plain terms

A GB-licensed site has a Commission account on the public register, runs GAMSTOP, has the bonus cap binding it, runs the vulnerability check at the threshold, runs customer funds in a Commission-approved way and routes complaints through an approved ADR. An unlicensed site that takes GB customers has none of those: no GAMSTOP coverage, no Commission or ADR route, no British consumer redress if funds are withheld, no 10x bonus cap, no vulnerability check. Section 33 of the Gambling Act 2005 makes the provision of gambling facilities to GB customers without a Commission licence an offence, and the Commission works with search engines, registrars, hosts and payment providers on enforcement. Cease-and-desist notices are routine; the Commission has, or is about to have, court-order DNS blocking powers.

What is not on the books is an offence aimed at a customer who simply places a bet on an unlicensed site. That is why “legal to use” is the wrong frame. The right frame is what an unlicensed site lacks. Funds held under a Curaçao licence are governed by Curaçao law; funds held under a Maltese licence are governed by Maltese law. The reader’s protection follows the licence, not the website.

A reader who asks “is it legal?” and hears “yes” is being told something the statute does not actually say. What the statute says is that the operator is offending. What that means for a customer is that the customer has no Commission route when something goes wrong, and the customer has no GAMSTOP-mediated exclusion if exclusion is the goal. Honest framing: licensed = checks, limits, GAMSTOP, the bonus cap, a route for complaints; unlicensed = none of those and a real possibility of funds not being paid out.

Curling as a betting sport: the shape of the fixture list

A curling match looks quiet: two teams, eight stones each, a sheet of ice, and a tap-and-release rhythm that rewards a sort of geometric patience. As a betting sport it is smaller than football or tennis, and it has periods where most UK-facing bookmakers do not even show a curling market at all; the same is true for the United States and for most of continental Europe. What makes it worth a guide is the rhythm of its season: a long stretch of autumn opens, the European Curling Championships and the Continental Cup bridge into winter, the Olympic Games every four years and mixed doubles at the same Games since 2018, the World Men’s and World Women’s Championships in spring, and the Grand Slam of Curling events carried through the year. There is something for the bettor most weeks of the calendar, even if no single bookmaker always has it on the page.

The rules of the game give the market its shape. A curling team has four players (two in doubles), and each player throws two of the eight stones the team delivers in each end. Ends usually run eight or ten, with international competitive games at ten ends. Stones weigh between 17.24 and 19.96 kg under World Curling Federation rules. After sixteen stones have been played in an end, the team with the stone closest to the button (the target at the centre of the house) scores one point for every stone it has lying closer to the button than the opponent’s nearest stone, with only stones in the house counting. A blanked end — all sixteen stones cleared off the house without a scoring decision — leaves the hammer with the same team, and the hammer is the last stone of the next end. Tied games go to extra ends.

A point-a-stone-counting model sounds like a market formula and it is one: match winner, total points over a set number of ends, handicap lines, correct score after a fixed number of ends and outright tournament winner are markets that come up in curling betting, along with a relatively consistent set of single-end props and outright futures on tournament stages. The structure of the sport — discrete ends, point totals that can be read on a scoreboard end-by-end — gives the data layer most bookmakers rely on to publish live odds, where they publish live odds at all. A sport whose scoreboard updates cleanly lets the in-play product work without a complex feed. Whether any one bookmaker takes that opportunity on curling is a brand-by-brand question, and the section that follows is what it actually looks like.

Curling became an official Olympic medal sport at the 1998 Winter Olympics; mixed doubles entered the Olympic programme in 2018. That is the anchor point for any futures market running through a Games year. The Olympic curling tournament is the single largest betting event the sport offers, with men’s, women’s and mixed doubles each running a round-robin and knockout. Olympic curling also comes with what most sports do not — a real risk that the page is published between Games, so the next bettable event is in four months rather than next week.

Fixtures the bettor actually watches

The competitive calendar for curling is dense once you know where to look. The European Curling Championships run in late November, the men’s and women’s fields running a round robin followed by a knockout. The Continental Cup, a mixed North America-versus-Europe event with skins and mixed doubles, follows. The World Men’s and World Women’s Championships follow in spring, run by the World Curling Federation. The Grand Slam of Curling runs four or five events a season across North America. The Olympic curling tournament is the Four-Year peak for outright markets. Mixed doubles is increasingly a separate event with its own bookmaker coverage.

The list is not exhaustive; smaller tour-level events fill the gaps, and bookmaker coverage rarely matches the calendar calendar-for-calendar. The fixture a reader bets on depends on whether the bookmaker has priced it. The bookmakers listed below do most of their curling offering through outright markets and a handful of match markets on the bigger events, and a couple of them push live odds on the bigger championships.

Markets the sport invites

Match winner, total points over a line, correct score after a fixed number of ends and outright tournament winner are the four markets a GB bettor can expect to see on a curling event with any meaningful coverage. Handicap lines — a side that gives stones at the start of an end, much like an Asian handicap in football — appear on bigger events and on platforms with a price-form layer for curling. A few bookmakers offer end-by-end correct-score props on featured matches, and that is where live odds have the most natural home. Outright markets — winner of the European Championships, winner of the World Men’s, winner of the Olympic gold — settle over weeks, so the market involves a notional year of risk on the punt.

What curling does not consistently offer at smaller events is depth: a single bookmaker with one outright line and one match line on an event is not unusual, and the punter has to take what is priced rather than shop for it. That is one reason the bookmaker-by-bookmaker comparison matters: a thin curling product on a major brand is still a choice a reader is making, and it changes which bets the bettor is forced into.

A ten-bookmaker field: how to read the comparison table

The table below lists ten GB-licensed bookmakers and what each one’s own terms state on the subject. The licence column is drawn from the Gambling Commission’s public register: every row carries the account number of the licence and the entity that holds it. The last column is what each operator’s own terms say about curling specifically, which is sometimes a sentence and sometimes a near-blank entry because the operator simply does not go deep on the sport.

The table is a procurement sheet for the reader. It is not a ranking. A reader who wants the deepest curling product in the set picks one row; a reader who only bets curling once a year picks another row; a reader who is really picking an all-rounder and curling is a bonus picks a third row. The columns that follow are what make that choice readable.

A short note on the licence column, because it carries more weight than the appearance suggests. Every licence number on the table is a Commission account; the same account can carry several trading names under one licensee, and a regulator’s register is the only place that the relationship is publicly visible. Checking before sign-up takes two minutes on the Commission’s own site. A line about curling on the betting platform is a question about an operator, not a statement of its licence.

What the table cannot show is the texture of a curling match in-play, which is the only area where the choice of operator tends to get loud. A reader looking for live odds will find a thinner field than a reader looking for an outright winner. None of the rows above is a refusal to offer curling outright; several are calendar-driven descriptions of the same commitment: markets appear when the schedule makes them available, and recede when it does not.

The angle on cost: what the rest of this article works through

Cost is the angle the rest of the guide uses. Curling offers are not headline-grabbing in the way a Champions League price-boost is, but they are exposed to the same pressures: an odds margin that has a number at its heart, a bonus with a turnover attached to it, a payment choice that has a fee baked into it, a verification gate that has a delay attached to it. The math behind what a bet pays, what a market keeps, what a free bet is worth and what a bonus really costs is in the next four sections. A reader who follows it once, on curling or any other sport, has a tool that doesn’t come off the page.

How an odds price is read: the math the bookmaker takes with it

A bookmaker’s margin — also called an overround — is the percentage of every pound bet on a market that the bookmaker keeps, on average over the long run, before any other cost. The rest, the payout share, goes back to winning punters. For a two-way market at decimal odds 1.90 and 1.90, the payout share works out at 1 ÷ (1/1.90 + 1/1.90), which is 1 ÷ (0.5263 + 0.5263) = 1 ÷ 1.0526, or about 95.0%. The margin is 1 minus 95.0%, which is about 5.0%. A £100 stake on either side at those prices puts about £5 in the bookmaker’s pocket on the round, before any other cost.

That is the floor under every discussion of bookmaker value that follows. A 5% margin on a head-to-head curling match is a realistic number for a smaller bookmaker on a smaller event — what the maths hands you on a clean two-way line. A 2% margin would be unusually tight for curling; a 10% margin would be loose even by smaller-event standards. The same formula at decimal prices 1.85 and 2.00 in a two-way market gives a payout share of 1 ÷ (1/1.85 + 1/2.00) = 1 ÷ (0.5405 + 0.5000) = 1 ÷ 1.0405 = 96.1%, so the margin is about 3.9%. The maths at 1.80 and 2.10 gives 1 ÷ (0.5556 + 0.4762) = 1 ÷ 1.0317 = 96.9%, margin about 3.1%. The same market, three sets of prices, three different margins — and the bettor is paying whichever one the bookmaker publishes.

It is important to flag the gap between “the margin is 5%” and “5% of every bet is lost”. The first sentence is true on average, over the long run, across many bets. The second sentence overstates the case on every individual bet: any single bet either wins (the punter keeps the profit) or loses (the punter loses the stake). The margin is a fraction of every pound that walks in the door of the market, and that fraction is invisible on any single slip. The reader’s practical question is what fraction of their long-run turnover the bookmaker keeps. For a 5% margin, every £100 betted on that market over a long period costs an average of £5, before any other cost the reader carries. A 1% margin change is not a small thing.

A two-way market is the cleanest example because everything in the formula above divides neatly. A three-way market — a curling match with a tie, where draw is a bookable outcome — has three prices in the sum and the margin is correspondingly higher for the same length of price. The maths is identical in shape.

What a winning bet pays back

Return is the second number on the slip, and it is computed the same way for every sport. For a single bet at decimal odds o, on a stake s, the return on a winner is s × o, the net profit is s × (o − 1), and the loss on a loser is the stake (s). On a £10 win bet at 1.90, the return is £19.00, the profit is £9.00; on a £5 win at 6.00 the profit is £25.00; on a £20 win at 1.50 the profit is £10.00. The example prices are easy to remember because they match common curling lines: a heavy favourite, a slight favourite, an outsider.

For a combination bet the odds of the legs multiply into a single price. Two legs at 1.90 and 1.85 combine to a price of 1.90 × 1.85 = 3.515, the same as the operator publishes; three legs at 1.90, 1.85 and 1.60 combine to 1.90 × 1.85 × 1.60 = 5.624. The stake is multiplied by the combined price once. A £10 stake on the three-leg combination returns £56.24 on the win; the bet only pays if every leg wins.

A market margin and a winning payout are different numbers and work differently for the punter. The margin is the long-run fraction the bookmaker keeps across all outcomes; the return is what a single winning bet pays at this price. They meet on the long-run arithmetic: over many bets on the same market at the same price, the win and the loss come through together in roughly the ratio the market and its margin imply, and the difference is the margin. A punt can’t beat the margin at one step, and a punt against a sharp bookmaker over hundreds of bets at the same price very rarely does, either. That is what the 5% on a curling match line is, in plain English.

How a bonus turns into a number the punt actually pays

A welcome bonus is the most heavily marketed line on every GB-licensed bookmaker, and the marketing is always the same: a “100% bonus” or a “£40 in free bets” headline, with the qualifier buried below. The qualifier is where the cost sits.

A bonus with a 10x wagering requirement needs a turnover of 10 times the bonus to clear. A £10 bonus needs £100 of qualifying bets; a £25 bonus needs £250 of qualifying bets; a £50 bonus needs £500 of qualifying bets. Since 19 January 2026 the 10x figure is a statutory cap rather than a market norm; a bookmaker offering 50x would be in breach. Even at 10x the multiplication matters: clearing a £10 bonus through a 5% margin market costs the punter, on average, £5. The bonus “pays” £10, and the cleaning of the bonus costs £5; the net is £5. A 50x bonus that pays £10 costs, on average, £25. Neither is a gift.

The minimum price for a qualifying bet widens the cost in the other direction. A bonus that requires a bet at minimum odds of 2.00 (1/1) limits the menus available to the punt, which means the bets cleared happen on markets the bookmaker wants them on, which means the margin the bet is paying is whatever those markets carry. A 5% margin cleared at 2.00 will not always be available; sometimes the qualifying menu only allows higher-margin markets. The number the bettor is clearing is rarely as clean as the marketing assumes.

A “free bet” is a different kind of offer, and the cost it carries is in its name. The stake is usually not paid back with the win. A £10 free bet at decimal odds 6.00 returns £60 if it wins, of which the punt keeps £60 profit (because the £10 stake never returns); if it loses, the punt keeps nothing. The expected value of the free bet on a fair market is the win-probability times that profit. On a market that the bookmaker prices at 6.00 (so the implied win-probability is 1/6.00 = 16.7%), and assuming the bookmaker takes no margin (which is unreal; 5% on a clean two-way market is more representative), the expected value is 16.7% × £60 = £10.00. With a 5% margin baked in across both sides (and the win-probability adjusted to 1/6.30 ≈ 15.9%), the expected value drops to about 15.9% × £60 = £9.52. Either way, the free bet is not worth its face value on a win, and it is worth nothing on a loss.

That is what the qualifier on the marketing line is telling the reader. A “100% bonus” headline is not a £100 gift; it is a £100 marketing figure behind a number of bets, at a minimum price, on markets the bookmaker specifies, that the punter has to clear before any of the bonus turns into withdrawable cash. Welcome bonuses are not for sign-up speed; they are a hedging cost. A reader who clears a bonus in the first month of betting is doing it on a margin that comes out of the bonus plus their own stake, and a 10x cap is the read of that cost on the page.

How a payment choice lands: the practical friction of moving money in and out

A credit card cannot fund a GB betting account, by law, and no GB-licensed operator will accept one. A debit card can; an instant bank transfer can; an e-wallet — funded by debit card, because credit card funding is also banned — can. The choice between debit card and bank transfer is largely operational: bank transfer payouts clear directly to the named bank account and clear cleanly, while debit-card payouts land faster but cannot exceed the original deposit. An e-wallet is a third route and a clean one for separating the betting pot from the main current account.

The verification gate costs the punter the first time the account is funded. Name, address, date of birth, payment method and a credit and fraud check against public records happen before the deposit clears, and they have happened every time since 7 May 2019. A reader who waits for a final to deposit is paying for the wait, because the verification step runs every time. Once the account is verified, the friction drops, and account-to-account payments clear quickly. The cost of this is the cost of choosing a GB-licensed site at all; that is the trade-off described in the section on the licence on the wall.

A withdrawal cap and a withdrawal speed are two different friction points. A cap is set by the operator and is rare on GB-licensed bookmakers on the main payment routes; a withdrawal speed describes how long the bettor waits for the funds to land. The fastest routes are debit cards and a few e-wallets, often same day on weekdays; bank transfers usually clear the same day once approved. Approval is not the same as clearance; a withdrawal approved at 4pm on a Friday can land over the weekend or on Monday. The cost of the slippage sits with the reader who needs the money sooner. Currencies at GB operators are GBP, so the bettor does not pay a foreign-exchange fee on their own transaction; an e-wallet in a non-GBP base currency may carry a fee, and that is a fee the wallet charges, not the bookmaker.

There is no statutory cap on stakes in sports betting; operators set their own maximum stakes and may restrict customers. A reader who has found a sharp curling price will sometimes find the stake capped on the platform, and that is a reading for another article; in the GB market the cap is operational, not regulatory.

The cost picture on one round trip

The simplest round trip on a GB-licensed account: deposit by debit card at £100, place a £10 bet at 1.90, win, place a £10 free bet at 6.00, win, request a withdrawal of, say, £100 by bank transfer. The deposit clears with no fee. The bet pays £19; the profit, after the £10 stake, is £9. The free bet at 6.00 pays £60; nothing comes back on the stake. The reader has £28 in winnings before the withdrawal fee, and the £100 stake returned on the first bet leaves the betting account at £119 minus whatever the betting activity cost the operator — and the operator’s cut is in the margin. The withdrawal costs the reader nothing on the bank transfer side; the verification that lets the withdrawal through was already completed on deposit. Time cost is the only extra; the operator did not charge for it.

A different round trip: deposit by debit card at £100, place a £10 bet at 6.00, lose, place a £10 bet at 1.90, win, request a withdrawal of, say, £50 by bank transfer. The reader loses £10 on the first bet, gains £9 profit on the second, and withdraws £50 to a bank account. The withdrawal does not cost anything on the bank transfer. The reader has lost £1 of their own money over the cycle and paid nothing to do it; the operator holds about 5% of every pound the cycle moved on the market, and that 5% is the price of the service. The two round trips together cost the reader £1; the operator kept the margin, the bonus cleared (or was never there to clear), the verification gate was paid at sign-up, and the bank transfer was free. That is what a GB-licensed market, kept inside its own rules, looks like.

The ten operators, reviewed

The bookmakers on the list share a Gambling Commission licence but are otherwise different businesses. Each review below says what the operator’s own terms state, what the licence register says in plain English, and where the operator stands for the reader whose primary sport is curling. The verdict at the end of each block is the judgment this guide makes after looking at the row, which the facts above do not on their own.

Fitzdares — premium positioning, in-play on the bigger sports

The licence is held by Fitzdares Limited under Commission account 400 with the categories on the register set to remote general betting standard (real events). The Fitzdares app listing names cash out, accumulators, Lucky 15s, specials and antepost markets on horse racing, football, tennis, rugby, cricket, golf and American football, with in-play live odds. Curling is not named in the app listing; the markets appear under the operator’s general calendar rather than as a stand-alone product. The premium positioning is evident in the brand presentation more than in a curling-specific offering.

A reader looking for a curling-specific product is buying calendar coverage rather than a feature set; a reader looking for a premium app with horse racing, football and a curling line at the European Championships finds Fitzdares a credible choice. The in-play product is more developed than the curling line; live odds on the bigger curling events are not guaranteed, and the reader who watches curling end-by-end may want a more curling-led product.

Verdict. A strong brand across the bigger sports, with a curling line that shows up at the bigger events rather than every week. The premium positioning and the in-play product make it a sensible second bookmaker rather than a primary curling book.

BetMGM — broad sports coverage, calendar-driven curling

BetMGM is operated under Commission account 39198 by LeoVegas Gaming PLC, with the register holding the standard remote general betting standard (real events) category. The brand’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 4+ selections and two sports multiples of 2+), valid for 7 days with minimum odds and an opt-in, and the bonus sits behind the standard minimum-price and 7-day clearing rules. The brand carries a broad sports calendar; curling markets appear under the operator’s general calendar and the depth varies with the calendar.

A reader picking BetMGM for the welcome offer is buying a multi-bet welcome product whose headline number (£40 in free bets) is conditional on the slots, the minimum odds and the 7-day window. A reader picking BetMGM as a curling bookmaker is buying calendar coverage rather than a curling-specific feature set.

Verdict. The brand is at its best on the higher-volume sports. Curling sits inside that volume rather than above it. Welcome offers carry a clearing cost on every additional wager; the brand is for the reader who is using curling as a calendar supplement to a broader sports book.

Kwiff — quirky market product, calendar-driven curling

Kwiff runs under Commission account 44448 held by Eaton Gate Gaming Limited, with the register holding the remote general betting standard (real events) category. The brand describes itself as a trademark operated by Spryme Ltd, and the App Store listing carries a 17+ age rating. Kwiff’s distinguishing commercial product is “charge” — a mechanic that boosts winning payouts at random, which is the feature that shows up at the operator’s marketing layer rather than at the betting-slip level. Curling markets appear under the operator’s general calendar.

A reader who likes Kwiff for its quirk is buying a different feel at the slip level; a reader buying it for curling is buying calendar coverage. The charge mechanic sits across sports and across the calendar; the curling side of the proposition is more conventional than the football side. A reader looking for a brand that has curling in mind as a product is reading the wrong feature; the calendar covers it.

Verdict. A calendar-driven curling book with a quirky market product elsewhere. Useful as a complement to a primary curling account rather than as the primary itself.

Lottoland — lottery-led, calendar-driven curling

Lottoland is operated under Commission account 38991 by EU Lotto Limited, with the standard remote general betting standard (real events) category. The brand sits at the intersection of lottery betting, sports betting, casino and scratchcards; the App Store listing carries the lottery framing prominently. Sports betting is a layer rather than the central product. Curling markets appear under the operator’s sports calendar.

A reader who likes Lottoland is buying the lottery and the casino layers; a reader buying it for curling is buying calendar coverage. A reader who wants a deep curling product in the Lottoland wallet is asking for something the brand does not promise, and the betting slip offers the calendar rather than the feature.

Verdict. A lottery-and-casino brand with a sports layer that includes curling under the calendar. The proposition is for the reader whose other wallets are elsewhere, not for the reader whose primary book is a curling book.

Midnite — in-play product, calendar-driven curling

Midnite is held under Commission account 101839 by Midnite Limited, with the remote general betting standard (real events) category. The site shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits; the Midnite home page carries an in-play product visible at the time of writing. The brand’s sports welcome offer is £25 in free bets and 50 free spins on a £5+ pre-match qualifying bet at minimum odds 2.0 within 14 days; the free bets are valid for 7 days. Curling markets appear under the operator’s general calendar.

A reader picking Midnite for the welcome product is buying a small-stakes welcome with a healthy minimum-odds condition and a 7-day window. A reader picking Midnite for curling is buying calendar coverage; the in-play product is shown alongside it. The acca builder and the price boosts are a deeper product layer than the curling line alone warrants.

Verdict. A brand whose product is in-play and aca-led rather than curling-led. The acca builder and the price boosts make sense on the bigger sports; curling sits in the calendar. A reader buying a curling-led book will find the line within the calendar; a reader buying a curling-first product finds it thinner.

Octobet — calendar-driven curling, lighter casino layer

Octobet is held under Commission account 62545 by Octopus Game Limited. The brand’s sportsbook welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus for new customers; the headline frame is risk-mitigation rather than deposit-matching.

A reader picking Octobet for the welcome product is buying a half-back structure on the first deposit, with the maximum at £50, and a small casino add-on that the size of the bonus does not match the headline figure; the same trade-off applies to clearing, where every additional wager carries a cost at the market margin. The free-bet frame carries the standard cost of a free bet whose stake is not returned on a winner.

Verdict. A calendar-driven curling book with a risk-mitigation welcome. A reader for whom the welcome product matters more than the per-sport product gets a brand that does what it says; a reader buying a curling-first book finds the calendar line thinner.

Unibet — established operator, broad sports calendar

Unibet is held under Commission account 45322 by Platinum Gaming Limited, Gibraltar, and has been operating since 1999 by the operator’s own account. The operator’s UK sports welcome offer is “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), with free bets expiring within 7 days of issue, for new GB customers using a debit card or instant bank transfer. The brand has featured curling in past seasons, with odds listed in the general sports calendar.

A reader picking Unibet for the welcome product is buying a £40 free-bet bundle behind a £20 minimum stake and a 2.00 minimum price, in a 7-day window; the bundle headline number is the sum of the free-bet slots, not a cash bonus. A reader picking Unibet for curling is buying calendar coverage with a brand that has run curling before.

Verdict. A long-established bookmaker with a broad calendar and a curling line that has historically appeared at the bigger events. Welcome cost is significant; the operative frame is the calendar rather than a curling-led product.

Fafabet — horse racing focus, calendar-driven curling

Fafabet is held under Commission account 57385 by Taichi Tech Limited. The brand pays Best Odds Guaranteed on UK and Irish horse racing win and each-way bets from 9am on race days: if the starting price is bigger than the original price, the bigger odds are paid. Coverage depth fluctuates according to the operator’s general schedule.

A reader picking Fafabet for horse racing is buying the BOG product, and the win is in the consistent price-up rather than the headline quote. A reader picking Fafabet for curling is buying calendar coverage. The brand is built around horse racing and the curling line is a calendar layer.

Verdict. A racing-led book with a calendar-driven curling line. Useful as a calendar backup; not a curling-led book.

Bet600 — racing and BOG, calendar-driven curling

Bet600 is held under Commission account 44731 by Tyche Tech Limited. The brand pays Best Odds Guaranteed on horse racing: if the starting price is bigger than the early or show price taken, the bet is paid at the SP.

A reader picking Bet600 for the BOG product is buying SP-paid upgrades on horse racing and a calendar-driven curling line. The product is racing-led; curling is a calendar layer.

Verdict. A racing-led brand with a calendar-driven curling line. Useful as a calendar backup; the BOG product is for racing rather than curling.

BetGoodwin — racing-led, calendar-driven curling

BetGoodwin is held under Commission account 2927 by Goodwin Racing Limited. The brand’s sports welcome offer is “Bet £10 & Get £15 in Free Bets”: £5 sports bet, £5 acca, £5 Sub-Cover bet, valid under the standard rules.

A reader picking BetGoodwin for the welcome product is buying a three-bet bonus with the standard clearing mechanics; the headline number is £15, and clearing it costs the bettor a fraction at the market margin. A reader picking BetGoodwin for curling is buying calendar coverage.

Verdict. A racing-led brand with a calendar-driven curling line. Useful as a calendar backup.

Picking on cost: what changes by reader profile

A reader who bets on curling only at the Olympics is buying calendar coverage and can pick by welcome offer, since the broader bookmaker discipline matters more than the curling product. A reader who bets on curling through the European Championships and into the World Championships is buying calendar coverage and live odds and should pick by the in-play product and the outright market presence. A reader who bets on curling all year and uses it as a primary sport is buying the calendar and the in-play product, and the player profile above the £150 threshold will be running vulnerability checks regardless of brand, which is a fixed cost of the licence and not a feature of any particular operator.

A reader on a small budget is buying deposit limits and self-control. The bonus cap matters in the other direction: the 10x wagering requirement applies to bonus offers, not to matched deposits, and the matched deposit is what most of these operators offer. The cost of a bonus is in the clearing, and a budget punter who clears a bonus on small stakes pays the same fraction of every pound at the margin that a higher-budget punter pays, but the absolute budget is tighter.

A reader with a sharp eye for a curling line is buying the calendar and the outright market depth. None of these brands market themselves as curling-led; a deep curling reader is buying one brand from the set above and another from a brand not in the set, if such a brand is preferred.

Reading the rest of the calendar: an operator-by-operator snapshot

Fitzdares is at its best on horse racing and football, with a curling line that appears at the bigger events; the operator’s app product is one of the more developed. BetMGM is broad; the welcome offer is a multi-bet product with cost behind the £40 figure and a 7-day clearing window. Kwiff is calendar-driven and quirky; the charge mechanic is its own product and is across sports rather than curling-led. Lottoland is lottery-led; curling is a calendar layer. Midnite is in-play and acca-led; curling sits inside the calendar. Octobet is calendar-driven; the welcome offer is a half-back structure. Unibet is established and broad; the welcome offer is a £40 free-bet bundle behind a £20 minimum stake and a 7-day window. Fafabet and Bet600 are racing-led with the BOG product on horse racing; curling is a calendar layer. BetGoodwin is racing-led with a £15 free-bet welcome, three-bet structure and standard clearing mechanics.

The thing that varies across the set is the in-play product and the broader brand positioning. A reader who wants a deep curling product needs more than one bookmaker, because every brand above is calendar-driven on curling rather than curling-led. The pair-of-bookmaker approach is the practical solution, and what the second bookmaker looks like varies with the first bookmaker’s calendar.

What the calculation hands you: a worked example

Take a two-way curling match market at decimal odds 1.90 and 1.90 — an example, not a quoted price. The payout share is 1 ÷ (1/1.90 + 1/1.90) = 1 ÷ 1.0526 ≈ 95.0%, so the margin is roughly 5.0%. On that single market, a £100 stake on either side at either price puts about £5 in the bookmaker’s pocket across a long-run average of bets at this price.

A £10 single bet at 1.90 returns £19 on a winner, for a profit of £9. A £10 combination bet on two legs at 1.90 and 1.85 — combined price 3.515 — returns £35.15 on a winner, for a profit of £25.15, but pays only if both legs win. The cost of the bet on a long-run average at the 5% margin is around 5% of the stake — so 50p on a £10 single on average — and the bet pays the same regardless of the cost on the winning leg.

A £10 free bet at 6.00 on a market that the bookmaker prices at 6.00 returns £60 on a winner, with the stake not returned. On a clean 5%-margin market, the long-run expected value is £10 × (6.00 − 1) ÷ 6.00 × 0.95 ≈ £7.92, a touch under the face value. The reader is paying for the staking rule and the margin in the long run; the bet pays what it says on a winner and nothing on a loser.

A £10 bonus at a 10x wagering requirement needs £100 of qualifying bets. On the 5%-margin market above, the expected cost of clearing the bonus is £100 × 5% = £5.00. The bonus pays £10 in cash, so the net is about £5. The marketing never quite says this; the maths does.

These three numbers — the 5% margin, the £7.92 free-bet value, the £5 net on the £10 bonus at 10x — are the figures a reader takes into the next season. They are not the same on every market, on every bonus or on every bookmaker, but the shape carries across.

Living with the cost: a one-page summary

A GB licence costs what it costs in friction, and the rest of the cost lives in the margin and the bonus structure. The shape of a curling betting account over a season looks like this:

The bookmaker earns its margin on every market the reader plays. The 5% example above is one reading; a tighter bookmaker on a tighter market is closer to 3%, a looser bookmaker on a less-traded market is closer to 7%. The reader pays the market margin on the long-run average and pays it on every additional wager during bonus clearing.

The bookmaker earns a marketing budget on welcome offers. The bonus cap at 10x means the headline number is the headline number and the cost is the cost on the same market the reader would have played anyway. A £40 free bet headline at the cap and a 5% margin costs about £16 in clearing on the round trip, with the £40 face value settled in stake-not-returned free bets. The arithmetic lands at a net about £24.

The bookmaker pays the £150 vulnerability check when it fires, which runs against the customer’s deposits minus withdrawals over 30 days. It is a public-record check, not an income check, and a £500 balance over 30 days fires it. The check is part of the licence, and the licence cost is the verification gate at sign-up. The punter’s cost is the time cost of going through it.

The bookmaker, and the reader, pay the deposit-choice cost on a payment that charges a fee. The bank transfer does not; a few e-wallets in non-GBP base currencies do. The credit-card ban removes that route entirely.

The licence cost is shared: the operator pays for it in compliance, the reader pays for it in friction, and the system gives back GAMSTOP, the bonus cap, the dispute-resolution route and the public register that any reader can check in two minutes. The reader’s question is whether the two minutes is worth the friction. The honest answer is that the friction is the licence, and the licence is what makes the rest work.

Frequently asked questions

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

For a single bet at decimal odds o and a stake s, the return on a winner is s multiplied by o, the net profit is s multiplied by (o minus 1), and the loss on a loser is the stake s. On a £10 bet at 1.90 the return is £19 and the profit is £9. Combination bet odds multiply the legs into one price, so two legs at 1.90 and 1.85 combine to 3.515 and a £10 stake returns £35.15 on a winner. The maths is the same for curling as it is for every sport.

Can you bet on curling from Great Britain?

Yes, at any of the GB-licensed bookmakers on the Gambling Commission’s public register. The Commission does not publish a permitted-sport list, so curling markets are offered under the operator’s general sports licence rather than a specific permit. A reader who wants to confirm a brand is licensed searches the public register by name, account number or domain and reads the entry for the brand’s licensee and the categories of licence held.

How is it checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is the whole test. It is searchable by business name, trading name, account number or domain, and it is free to use. The register entry names the licensee, the trading name, the categories of licence held and the dates it covers. Several brands run under one licensee, so two familiar trading names sometimes share a Commission account. The access date on the search is the only thing that ages.

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

The margin is the fraction of every pound bet on a market that the bookmaker keeps, on average over the long run. For a two-way market at decimal odds 1.90 and 1.90 the payout share is 1 divided by (1/1.90 plus 1/1.90), which is about 95.0%, so the margin is about 5.0%. A margin of 5% on a curling match market is a realistic floor. The same arithmetic at 1.85 and 2.00 gives a margin of about 3.9%; at 1.80 and 2.10 a margin of about 3.1%. The shape of the price carries the margin.

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

A fractional odd of a divided by b converts to decimal by dividing a by b and adding 1, so 5/1 is 5 divided by 1 plus 1 = 6.00. 11/4 is 11 divided by 4 plus 1 = 3.75. Evens (1/1) is 1 divided by 1 plus 1 = 2.00. The decimal number is what the bettor’s stake is multiplied by on a winner, and the profit is the decimal minus 1 multiplied by the stake. The conversion is the same for any sport, including curling.
