Best gambling sites, scored on the official numbers: what casino, betting and bingo really keep

Picking a site in five lines

• Score the product, not the brand. Across British online gambling in the year to March 2026, operators kept 4.51% of casino stakes, 9.80% of betting stakes and 16.75% of bingo stakes. No welcome offer anywhere moves a number of that size, because the margin applies to every pound you stake and the offer applies once.
• Per pound is not per hour. Bingo keeps the most of each pound and still costs least an hour, because you stake so little through it. In a simulated 400-player room, six 10p tickets across twelve games put £7.20 through and cost £1.21, while £20 played at 20p on a model slot turned into £50 of stakes inside half an hour.
• The licence line settles everything that is not price. Hold a Commission licence and you must check identity before play, belong to Gamstop, turn credit cards away, offer a deposit limit before the first payment, keep bonus wagering to ten times, keep one product type per offer, and finish a complaint inside eight weeks with an independent body waiting beyond it. A licence from anywhere else brings none of that, whatever the offer says.
• In bingo, room size changes how often you win and not what it costs. Six 10p tickets won something in 7.83% of simulated games in a 40-player room and in 0.85% of games in a 400-player one, and the average return was 49.95p either way. The big room pays rarely and pays large.
• If you want an offshore welcome, read the wagering line first. Each is a deposit package opening at £20 or €20 with 35x to 40x attached, where a British licensee has been held to ten times since 19 January 2026. In places a free bet is added, which is the only betting element anywhere in such a package.

One rule to keep: work out the price of the thing you play most, then judge the site on everything else.

Scoring any gambling site in six calls

1. Call one: the licence. Scroll to the very bottom of the site, find the company that holds the licence and its Gambling Commission account number, and put that number into the public register to check the company matches. There is no grading here. Either a site holds a British licence or it does not, and an offshore cashier holds one issued somewhere else. A cashier that takes cryptocurrency, or marketing built around not being on Gamstop, answers the question before you look anything up.
2. Call two: the price of the thing you play. For a slot, the return percentage in the game’s information screen, because the same title is supplied at several. For a table, the rules panel: one zero or two, whether la partage applies, what the banker commission is. For a bet, add up one divided by each price in the market and see how far past 100% it goes. For bingo, the prize description, because no room is obliged to publish a percentage at all.
3. Call three: the size of the room or the market. This is the bingo-specific call and the one most scorecards miss. A pot shared between everyone who bought tickets behaves completely differently in a quiet room and a full one, and a pot with a published minimum behaves differently again. For betting, the equivalent is comparing the same market at two or three books, because the margin is the only thing you can shop for.
4. Call four: the offer, read from the wagering line upwards. At a British-licensed site the wagering cannot exceed ten times the bonus, and since 19 January 2026 one incentive may not contain more than one product type, so bingo tickets and slot spins can no longer share a single offer with linked terms. Operators now run two separate welcomes and ask you to choose. Read which one you are opting into before you click.
5. Call five: the way out. Open the withdrawal page before you deposit anything. Find the minimum payout, any fee, and what documents are wanted; then send the documents on day one, while nothing is waiting on them. At a licensed site a pending withdrawal cannot be handed back to you to play again, a rule that has applied since 31 October 2021.
6. Call six: the brakes. Before the first deposit, find the deposit limit and the time-out in the account settings and set one of them. A British-licensed site has had to put that choice in front of new customers since 31 October 2025. Anywhere else, nobody is obliged to offer it, so you go looking.

Six calls take about ten minutes on a phone, and they work the same way on a bingo lobby, a sportsbook and a casino. If the first call goes badly, nothing in the other five rescues it.

What each product keeps from every pound

The Commission’s annual industry statistics, published on 17 September 2026 for the year to March 2026, give turnover and gross gambling yield side by side for each remote product. Turnover is what players staked; yield is what operators kept once winnings were paid. Divide one by the other and you have the price of the product, with no illustration or assumption anywhere in the sum.

Those are sector-wide averages across every operator, every room, every market and every stake in the country, which makes them the only figures on the subject that nobody has chosen. They are also the only honest answer to the question bingo players ask most often, because a bingo room is not required to publish a payback percentage at all. Under the Commission’s technical standard RTS 3 a site may describe how its prizes are allocated instead of quoting a number, and most do.

The bingo figure has been drifting one way for a decade. In the year to March 2016, 91.67% of ticket money came back as prizes. By 2022-23 that was 83.02%, and the latest full year puts it at 83.25%. Players are getting back about eight pence less in the pound than they did ten years ago, and nothing in any lobby announces it.

£882.2m staked − £147.8m kept = £734.4m returned    £734.4m ÷ £882.2m = 83.25%

Before anyone concludes that bingo is a bad deal, read the next two sections. A margin per pound staked is not a cost per hour, and the gap between those two ideas is the most useful thing on this page.

The dearest pound sits in the smallest market

Put the same official table next to itself a second way, and the shape of British online gambling appears. The product with the highest margin per pound is the one almost nobody stakes anything on.

The staked column for casino and betting is this page’s arithmetic, the published yield divided by the published margin, and the rounding is why the three lines do not add exactly to the published total of £152.3bn. The shape survives the rounding easily enough: online bingo accounts for 1.78% of what the three products keep and 0.58% of what passes through them.

A slot recycles the same pound many times in an evening, because every win is restaked, which is how £5.7bn can be kept from a 4.51% margin. A bingo ticket is bought once and does not come back round; your £10 of tickets is £10 of turnover and nothing more. That single difference explains the whole table, and it is why the margin comparison needs the hour comparison beside it.

For scale on the other side of the ledger: bingo halls kept £703.8m over the same year, which is 4.8 times what online bingo rooms kept, and £461.7m of that came from the gaming machines in the clubs rather than from bingo itself. Online bingo turnover has fallen about two fifths since 2015-16. This is a small and shrinking corner of a large market, which is worth knowing when a site tells you its rooms are the biggest anywhere.

The number of people behind those sums is published too. In the Gambling Survey for Great Britain’s annual report of 16 July 2026, 47% of adults said they had gambled in the previous four weeks and 38% had gambled online, but that second figure drops to 16% once everyone whose only online gamble was a lottery ticket is left out. Most people who gamble online buy a draw ticket and nothing else, which is worth remembering whenever a site describes its rooms as busy.

Two more official numbers help you judge how much choice you actually have. At 31 March 2026 there were 2,154 gambling operators in the British market, down 1.1% on a year earlier, holding 3,097 licensed activities between them, of which 630 were in the combined remote casino, betting and bingo category. That category bundles all three products together, so it is not a count of bingo sites, and the number of brands is far larger than the number of licence holders, as the section on groups explains.

The same £20, three ways

Twenty pounds in an account buys a very different evening depending on where it goes, and the margin table above tells you almost nothing about which evening you would rather have. So here is the same money through each product, with the casino and bingo figures simulated on this site’s own models and the betting figures worked out exactly from prices.

First the reels. The House model slot returns 96.1%, pays something on 26.94% of spins, reaches its bonus round about once in 145 spins and caps a win at 2,500 times the stake; it copies no real game. Give it £20 and a flat 20p stake for 250 spins, which is roughly half an hour at the national pace. Across 100,000 simulated sessions, 74.7% of balances could still cover a stake at spin 250, the middle session closed on £9.95 and the average on £18.13. Just over a quarter, 27.4%, finished above the £20 they started with, 7.0% finished on £50 or more, and the best session in a hundred reached £155.46. Play all 250 spins and £50 has gone through the game at an average cost of £1.95.

Now the tickets. Picture a 400-player room where everyone buys six tickets at 10p, running twelve games in the hour, with 83.25% of the ticket money going back out as prizes, which is the sector’s own share applied to a model room rather than any operator’s published figure. Six tickets a game across twelve games is 72 tickets and £7.20 spent. Across 200,000 simulated hours the expected return is £5.99 and the expected loss £1.21, both exact because every seat in the room is identical. Everything else comes from the draw: the middle hour returned nothing at all, 90.16% of hours produced no win of any kind, 9.84% finished ahead, one hour in a hundred returned £99.90 or more, and the best hour in the whole run paid £239.76.

And the bet slip. Take an illustrative three-way football market priced at 2.05 for the home side, 3.50 for the draw and 3.70 for the away win, invented for this page rather than taken from any book. Those prices imply 48.78%, 28.57% and 27.03%, which add up to 104.38%.

1 ÷ 1.0438 = 95.81% paid back    margin 4.19%    treble: 0.9581 × 0.9581 × 0.9581 = 87.93%

Read the first two rows together and the paradox from the margin table dissolves. The bingo room keeps nearly four times as much of each pound as the slot does, and still costs less for an hour of play, because the slot was handed £50 of turnover from a £20 balance in half an hour while the room took £7.20 in a whole hour. The money you stake, not the margin, is what sets the bill.

Read the third and fourth rows together and you have the betting equivalent. The same prices cost 84p across ten singles and £2.41 across ten trebles, because every extra leg multiplies the margin in again: 4.19% on a single becomes 8.21% on a double and 12.07% on a treble. A treble at those prices is dearer per pound than any single market on this page and dearer than online bingo’s sector margin.

Scoring the casino half: the version decides it

The sector margin of 4.51% is an average across everything from blackjack to a low-paying slot build, and the spread underneath it is enormous. On the casino side the number you are scoring is not the brand but the copy of the game the operator installed.

Providers supply the same title at several returns and let the operator choose. Play’n GO puts Book of Dead out at 96.21% and supplies rungs beneath it at 94.25%, then 91.25%, then 87.25%, then roughly 84.2%. Hacksaw Gaming does the same with Wanted Dead or a Wild, published at 96.38% with 94.55%, 92.33% and 88.42% underneath. Blueprint Gaming lists Eye of Horus from 96.31% down to 90.25% and Fishin’ Frenzy from 96.12% down to 90%, and the 2025 Light and Wonder version of Rainbow Riches runs from 96% down to 87%. Nothing on the reels says which one you have; the figure is in the information screen.

One title, two rungs: Book of Dead costs £3.79 per £100 staked at its default and £12.75 at 87.25%, which is a bigger swing than the gap between any two products in the official table. That is why the casino scorecard line is the information screen rather than the brand, and why the guide to finding the top-paying version is the most practical page in this section.

Live game shows publish less. Evolution puts Crazy Time’s theoretical return between 94.41% and 96.08% depending on which spot you back, which is the range in the table. For Lightning Roulette it publishes the mechanism, one to five lucky numbers a round carrying multipliers of 50x to 500x, with unmultiplied straight-up bets paying 29 to 1 rather than 35 to 1, but no overall return on the game page, so none appears here. MONOPOLY Live and Infinite Blackjack likewise carry no published figure.

Scoring the betting half: the margin is in the price

A bookmaker does not charge a commission. It builds its margin into the odds, so the implied chances of every outcome add up to more than certainty, and the excess is the price of the bet. Working it out takes a calculator and about twenty seconds.

Backing all three outcomes in those proportions costs £104.38 and returns £100 whatever happens, so the market pays back 95.81% and keeps 4.19%. That is cheaper per pound than a slot returning 95.5% and far cheaper than the official 9.80% the whole British online book kept last year, which tells you something useful: the sector figure is carried by multiples, in-play markets and the sports where prices are loosest, not by the headline market on a Saturday football match.

Multiples are where the margin compounds. Each leg multiplies another 95.81% into the payback, so a double keeps 8.21%, a treble 12.07% and the sums only get worse from there. A £20 stake spread across ten singles at those prices costs 84p on average; the same £20 across ten trebles costs £2.41. If you like accumulators, that is the price of the pleasure, and it is worth knowing in pounds.

Two rules matter more on the betting side than anywhere else. The first is that the £5 and £2 stake ceilings belong to online slots alone, defined as reel-based casino games played online, while the gap between game cycles is 2.5 seconds on a slot and 5 seconds on other casino games, peer-to-peer poker apart. Neither reaches a bet slip. The second is the mixed-product ban: since 19 January 2026 a single incentive may not contain more than one of betting, casino, bingo and lottery, so a free bet can no longer be the route into casino spins at a licensed site, and a casino bonus cannot require a bet. A package from an offshore cashier can include a free bet alongside a casino offer, which is possible precisely because that casino is not licensed here.

Scoring the bingo half: no percentage, so read the pot

Bingo is the product the other scorecards skip, and it is the one that needs a scorecard most, because the number you would want is not published. Under technical standard RTS 3 a room may set out the way its prize money is shared out in place of a return figure, so what you get to read is a description rather than a percentage. Four things in that description are worth scoring.

How the pot is funded. A shared pot is a slice of ticket sales, which means the number in the lobby moves while tickets are still selling and a quiet room pays less. One operator’s own help page puts it plainly: what you can win depends on how many tickets were sold and what they cost. A pot with a published minimum is a floor the operator has set itself and is on the hook for, so a quiet room pays the same and your share of it is larger. If a room will not say which kind it is, that is the thing to walk away from.

How many tickets everyone else is holding. Your share of any prize is your tickets divided by all the tickets in play, which is arithmetic rather than luck. This page simulated the same six 10p tickets in two rooms, with 83.25% of the ticket money paid back as prizes in both.

The last row of that table is the one worth remembering. A bigger room is not a worse deal and not a better one: the average return is identical to the penny, because every seat is the same. What changes is the shape. The small room pays you about once in thirteen games and pays £6.40 when it does; the big room pays about once in 118 games and pays £58.01. Pick the one that suits what you want an evening to feel like.

How quickly the room finishes. More tickets in play means somebody completes sooner. In the 400-player room the full house typically landed on call 56 and the first line on call 17, against call 64 and call 25 in the 40-player room, while your own best ticket did not complete until call 79 either way. That is also why a jackpot written as a full house inside a set number of calls is only winnable in a busy room, which the bingo jackpots guide works through properly.

The ticket cap. Rooms publish a maximum number of tickets per player per game, and it ranges enormously, from six in some promotional rooms up to 96 or 120 in penny rooms, with one hourly session product fixing everyone at fifteen tickets for a flat £5. The cap is what limits your share of the pot, so it matters more than the ticket price. The bingo site comparison scores rooms on each of these points in turn.

One account, three products, and the rules that reach each

Most people on a multi-product site assume the protections are the same everywhere in the account. Most of them are, and the exceptions are worth knowing.

Seven of those rules travel with the account whatever you are playing. Age and identity have had to be confirmed before any gambling, demo play included, since 7 May 2019. Every licensed online operator has belonged to Gamstop since 31 March 2020, so a single registration shuts the sportsbook and the bingo rooms along with the casino. Credit cards have been barred for gambling since 14 April 2020. A pending withdrawal cannot be handed back to you since 31 October 2021. Anyone opening an account has been asked to pick a deposit limit before paying in since 31 October 2025. And from 19 January 2026 the wagering on a bonus has been held to ten times its value, with each incentive limited to one product type.

Two rules never leave the casino side. The stake ceilings of £5 from the age of 25, in force since 9 April 2025, and £2 for 18 to 24 year olds, in force since 21 May 2025, apply to online slots, which the regulations define as reel-based casino games played online. The minimum gap between game cycles is 2.5 seconds on a slot and 5 seconds on casino games that are not slots, peer-to-peer poker aside. Neither reaches a bet slip or a bingo ticket, so the cheapest-looking product on the official table is also the one with no legal ceiling on what a single purchase can cost.

And one line is missing entirely on the bingo side. A slot shows you a return percentage in its information screen; a bookmaker’s margin can be read off the prices; a bingo room may publish neither, because RTS 3 allows a description of prize allocation instead. That is the single biggest gap in consumer information across the three products, and it is why this page leans on the sector figure of 83.25%.

Whose record you inherit when you open an account

Brands are marketing; the licence is what you are actually contracting with. Enforcement is recorded against whichever company holds that licence, not against the name on the logo. On a bingo-led site that distinction is unusually sharp, because so many bingo brands sit on shared licences.

Two of the biggest names in British online bingo are on one of them: Jackpotjoy and Double Bubble Bingo both run as active domains on Gamesys Operations Limited, Commission account 38905, which also carries Virgin Games, Monopoly Casino and Rainbow Riches Casino on the same casual-games platform. Pink Casino is operated by LeoVegas Gaming PLC, account 39198, and its progressive jackpot is shared across the LeoVegas network, which is worth knowing before you judge a pot by the size of the brand. Grosvenor Casinos and Magical Vegas sit together on Rank Interactive (Gibraltar) Limited, account 57924. Amazon Slots runs on Jumpman Gaming, account 39175, registered in Alderney, a white-label operator carrying 234 domain names on the public register with 19 of them live; a first deposit there turns a prize wheel, which makes the headline number the best segment that wheel holds rather than the one most people land on. Every one of those registrations was checked on 10 October 2026.

Networked pots work the same way. Gala Bingo’s promotions carry the line that prizes are shared across the Entain bingo network, so a pot can be funded by players at more than one of that group’s brands, Foxy Bingo included. Entain also owns Ladbrokes and Coral in the high street and Gala Casino, PartyCasino, bwin, Sportingbet and Party Poker online, with several brands behind shared accounts, so a welcome taken at one can spend your entitlement at the next. Its largest Commission figure is £17m, from 2022.

Across the rest of the market, the records are public and worth a minute. evoke holds 888 Casino, trading online since 1997 and built for ten years on advertising that led with no-deposit spins, alongside 777 Casino and 888sport, with William Hill added to the group during 2022; its two largest figures are £19.2m from 2023 and £9.4m from 2022. bet365, privately held in Stoke-on-Trent, owns Heart Bingo, leads with its sportsbook and bases casino welcomes on a deposit, with £582,120 from 2024 on its record. Kindred, now inside FDJ United, pairs the casino-led 32Red with the sport-led Unibet and carries £7.1m from 2023. Betway sells both halves under one name with £11.6m from 2020. Flutter keeps Sky Vegas as its casino-led name, the brand there people link most readily with spins that cost nothing to claim, while Paddy Power, Betfair and Sky Bet lead with the sportsbook. MrQ, from Lindar Media, and PlayOJO, from SkillOnNet, attach no wagering to anything they hand out. Betfred carries £3.25m from 2023, and Genting Casino and Admiral Casino, owned by Novomatic, trade from premises as well as websites. Names such as Sun Bingo, Fabulous Bingo, Casumo, NetBet, Kwiff, Midnite, LiveScore Bet, Hollywoodbets, Lottoland, Tote and The Pools each print their licence holder and its account number at the foot of the site, and the register settles both inside a minute.

Whichever of them you choose, the floor underneath is identical: identity confirmed before play, a place inside Gamstop, no credit cards, no coin wallet in the cashier, wagering held to ten times at most, and a complaint that has to reach a conclusion inside eight weeks, after which the site must name the independent body that will weigh your case. The regulator describes itself as no ombudsman and settles nobody’s individual dispute, which is precisely why that independent body matters.

What a licence issued elsewhere leaves out

Casinos licensed offshore are regulated from Curaçao, Anjouan and Costa Rica instead. For a casino player that means no stake ceiling, no 2.5-second floor under a spin, no block on selling entry to a bonus round and no cap on wagering beyond the 35x to 40x already printed in the terms. For a bettor it means the mixed-product ban does not apply, which is why a free bet can sit inside a casino package there. For a bingo player it means very little, because these are slot-led offers and not one of them is a bingo offer at all.

For everyone it means the same list of absences: no Gamstop, no prompt to set a deposit limit, no eight-week deadline on a complaint, no named adjudicator at the end of it, no regulator here with any power over the operator, and no bank protection at all if the deposit was made in coin. The terms do say identity papers are wanted before a first payout is released, which is a fair thing to ask and a thing to settle early.

The names behind the better-known offshore lobbies are not hidden. Santeda International B.V. runs five of them on one Curaçao licence, Donbet, Velobet, Mystake, Rolletto and Goldenbet, so five sets of branding amount to a single counterparty with uncapped wagering and no British route for a complaint. NineWin and Kinghills are recent arrivals from Curaçao-registered families of sister sites, too new for anyone to have a record of how they behave, and promoted here through pages advertising their distance from Gamstop. Rainbet trades as RBGAMING N.V. under an Anjouan licence with a cashier built for Bitcoin and other coins, which British licensees do not offer. Gamdom and Roobet are two further Curaçao crypto casinos with roots in the trade in game skins. Not one of them holds a British licence. The law makes serving customers here unlicensed an offence by the operator rather than by the person playing, which is of no practical help to anyone whose balance has gone quiet. The offshore betting guide and the rest of that section review them one at a time.

Price an hour of whichever one you play

The first calculator prices an hour of bingo on the sector’s own figures: 10p tickets, 72 of them across twelve games, with 83.25% of the money coming back as prizes. That is the hour simulated further up, and it comes to about £1.21.

The second prices a casino sitting. It opens on 250 spins at 20p on a game returning 96.1%, which is the half-hour on the model slot above and about £1.95. Change the return to whatever the information screen shows you. European roulette is 97.3, a French wheel’s even-money bets with la partage come to 98.65, and baccarat’s banker bet is 98.94.

For a betting market, work out the payback first by adding up one divided by each price and dividing one by the total, then put that figure in as the return: 95.81 for the illustrative market above, or 87.93 for a treble built from three of them.

Keeping one account from becoming three habits

A site that sells casino, betting and bingo from one balance makes it easy to move between them without noticing that the evening has got longer. The settings that help are the same ones as anywhere else, and they are at their most useful before the first deposit.

Set a deposit limit, which a licensed British site has had to offer new customers since 31 October 2025, and remember that it covers the whole account rather than one product. Use a time-out when you want a short break from one site. Gamstop closes every licensed British site in a single registration, across all three products at once, and has covered every online licensee since 31 March 2020. It has no reach over a casino licensed somewhere else entirely.

Beyond the operator, two layers help. Most banks will refuse gambling payments on your bank card once the block is switched on in the app, and several hold it in place for a cooling-off period before lifting it. GamBan blocks gambling sites on every device you install it on, which covers the sites Gamstop never will. If any of it has stopped feeling like a choice, GamCare answers the National Gambling Helpline on 0808 8020 133, free of charge, in confidence, at any hour of the day, and our play safe page keeps every tool in one place.

Where these figures come from

The product margins are computed from the Gambling Commission’s annual industry figures covering April 2025 to March 2026, which appeared on 17 September 2026 and give turnover beside gross gambling yield for each remote product. Margin per pound staked is yield divided by turnover: bingo £147.8m of £882.2m, betting and casino from the same table. The staked figures for casino and betting are this page’s own division of published yield by published margin and are rounded; the published total for the three products together is £152.3bn of turnover and £8.3bn of yield. The ten-year bingo comparison uses the same table’s 2015-16 line.

Casino house edges follow exactly from the rules for roulette and baccarat, with one zero or two, la partage on even-money bets, a 5% commission on winning banker hands and the tie paid at 8 to 1; the blackjack figure of about 0.5% assumes basic strategy on common six-deck rules and is an approximation, because tables and decisions vary. Slot and game-show figures are the providers’ published returns. Betting figures are exact arithmetic on prices invented for this page: implied chance is one divided by the decimal price, payback is one divided by the sum of those chances, and a multiple’s payback is the product of its legs.

Simulated figures come from this site’s own models, which copy no real game and no operator’s room. The House model slot returns 96.1%, pays on 26.94% of spins, reaches its bonus round about once in 145 spins and caps a win at 2,500 times the stake; it ran 100,000 sessions of £20 at a flat 20p, stopping after 250 spins or when the balance could not cover another stake. The bingo figures come from a draw simulated ball by ball with real British 90-ball tickets dealt off strips of six: 62,500 games for the 400-player room, 200,000 for the 40-player room and 200,000 simulated hours for the session figures, every player holding six 10p tickets, twelve games to the hour, with 83.25% of ticket money returned as prizes. That payback is the published sector share applied to a model room; it is not any operator’s figure, and no room is obliged to publish one.

Rules, dates, licence counts and participation figures are the Commission’s, the last from the Gambling Survey for Great Britain’s annual report of 16 July 2026. Brand facts cover ownership, licence holders, account numbers, offer formats and published enforcement figures only, each checked on 10 October 2026, and nothing here says that a named brand is running a particular offer today. Those package shapes are described as their published terms stood in October 2026.
