Independent UK casino comparison

Six licensed UK casinos, ranked by how they feel in your hand.

We judge these operators the way most people play now — on a phone. No hype, just what each one does well, where it falls short, and who it actually suits.

Game House Criteria is an independent, affiliate-funded site. We don't run games, hold your money or take part in any gameplay — we only review and compare.

How we grade

Eight checkpoints, weighted towards the phone

Every operator here holds a UK Gambling Commission licence — that's the floor, not a selling point. From there we look at the game range, the live casino, the studios behind the games, customer support and, above all, how the whole thing holds up on a phone. The letter grade is our shorthand for that overall picture, with the mobile and app experience pulling the most weight.

Head to head

Three duels, one question each time: which is easier to live with?

Rather than one flat table, we've paired the six operators into matchups that actually make sense, then talked through where each one edges ahead.

Kwiff

Grade

Duelz

Grade

Two brands that treat the phone as the main screen rather than an afterthought. If you rarely open a laptop to play, this is the pairing worth reading first.

App polish

Kwiff. A native app on iOS and Android that feels quick and considered, with quick-load slots and a tidy live-casino tab.

Duelz. No separate download; the mobile web app is fast and full-screen, and the gamified progress bar sits front and centre.

Casino depth

Kwiff. Casino sits alongside a full sportsbook, so the slots count is good rather than enormous.

Duelz. More single-mindedly a casino, so the slots and live rooms are the whole point rather than a side dish.

Personality

Kwiff. Playful but restrained; the 'supercharged' odds gimmick is a sportsbook thing more than a casino one.

Duelz. Leans hard into the duel-and-level-up theme, which will either pull you in or wash over you.

Our take

Pick Kwiff if you want one polished app covering sport and casino together. Pick Duelz if you only care about casino and quite like a bit of gamified structure while you play.

Admiral Casino

Grade

10Bet

Grade

The two most established names in this group, both carrying a fair bit of history. Their mobile answers, though, come from opposite directions.

Slots library

Admiral Casino. Heavy on Greentube and Novomatic titles that trace back to the arcade and high-street machines.

10Bet. A broader mix across studios like Pragmatic Play and Play'n GO, spread across sport and casino.

Live casino

Admiral Casino. An Evolution-powered live area that covers the usual tables competently.

10Bet. Also Evolution-driven, and given equal billing with the sportsbook rather than tucked away.

Mobile approach

Admiral Casino. Mostly the mobile browser; there isn't a standout dedicated app to lean on.

10Bet. Both a mobile site and an app, neither flashy but both dependable.

Our take

Go with Admiral if the Novomatic and Greentube slot names are what you're after. 10Bet makes more sense if you want one account spanning sport and casino with a proper app behind it.

Hollywoodbets

Grade

DragonBet

Grade

Both started as bookmakers and added a casino, so neither is casino-first. The gap between them is mostly about scale.

App availability

Hollywoodbets. Proper iOS and Android apps that are pleasant to use day to day.

DragonBet. A quick mobile site rather than a fully featured native app.

Casino breadth

Hollywoodbets. A growing slots and live-casino section sitting beside the sportsbook.

DragonBet. A smaller casino corner; slots are there, but they're clearly not the priority.

Who it suits

Hollywoodbets. Players who want a bigger brand with sport and casino under one roof.

DragonBet. Fans of a lean, independent bookmaker who only dabble in casino games.

Our take

Hollywoodbets is the fuller package if the casino side matters to you. DragonBet is the better fit if you mainly bet on sport and treat slots as an occasional extra.

No. 1

Admiral Casino

Grade

Novomatic slotsArcade heritageBrowser-first

Admiral is the online arm of the arcade name you've probably walked past on plenty of British high streets, and it's run by Greentube, the digital studio inside Austria's Novomatic group. That lineage shows in the slots, with a lot of Greentube and Novomatic titles you won't always find elsewhere, and on a phone it leans on the mobile browser rather than a standout dedicated app.

Hollywoodbets

Grade

Sports-ledSolid appsLive tables

Hollywoodbets built its name as a South African bookmaker before bringing the brand to UK players, so the sportsbook is still the loudest part of the site. The casino and slots section has grown up around it rather than leading it, the Android and iOS apps hold up well for everyday use, and there's a live dealer area if you'd rather sit at a table than spin reels.

Kwiff

Grade

App-firstOdds boostsPolished mobile

Kwiff made its name with the 'supercharged' idea, where random boosts fire on some sportsbook bets, but the app is the real draw for casino players too. It's one of the more polished mobile-first operators here, with slots and a live casino tucked neatly into a genuinely slick app, and the whole thing skews younger and more playful than the older high-street names.

10Bet

Grade

Since 2003Sport + casinoBroad slots

10Bet has been running since the early 2000s, which for an online casino counts as proper heritage, and it still divides its attention fairly evenly between sport and casino. You get a wide slots library, a capable Evolution-powered live casino, and a mobile setup that does the job across both the browser and the app without ever trying to be the flashiest option in the room.

Duelz

Grade

Gamified playMobile-firstLevel-up rewards

Duelz wraps its casino in a light role-playing theme where you battle, level up and collect rewards as you play, which is either good fun or beside the point depending on your mood. Underneath the gamified surface it's a slots-and-live-casino site much like the others, and it has clearly been built mobile-first, so a phone is where the whole experience feels most at home.

DragonBet

Grade

IndependentWelsh bookmakerLean & quick

DragonBet is a smaller independent Welsh bookmaker, and it wears that underdog status openly instead of pretending to be one of the big chains. Sports betting is the heart of it, the casino and slots corner is noticeably more modest than the rest of this list, and the mobile site keeps things straightforward and fast rather than piling on features you'll rarely touch.

Common questions

Before you click through

Is Game House Criteria run by any of the casinos it lists?

No. We're an independent site and we don't run games, hold your money or take part in any gameplay. We make money through affiliate links, which means if you sign up with an operator after clicking through, we may earn a commission. That doesn't change the grades or what we write about each site.

Are all six operators licensed to offer casino games in the UK?

Yes. Every operator on this page holds a licence from the UK Gambling Commission, which is the regulator for gambling in Great Britain. You can always check a company's licence status yourself on the Commission's public register before you sign up anywhere.

Which of these is best on a phone?

It depends on whether you want an actual app or just a good mobile site. Kwiff and Hollywoodbets have the strongest native apps here; Duelz is built around a fast mobile web experience with no download; Admiral and DragonBet lean on the browser. We weight the mobile and app experience heavily because that's how most people play now.

How does GamStop fit into all this?

GamStop is the free national self-exclusion scheme. Register with it and you're blocked from all UKGC-licensed gambling sites, including every operator we list, for the period you choose. Because these are all licensed operators, they're all part of GamStop, so it's a real safety net if you decide you need a break.

Should I trust the welcome offers you mention?

Treat them as a factual data point, not a reason to sign up. We list the type of offer each site runs, but the exact terms, wagering requirements and minimum stakes live on the operator's own pages and change over time. Always read those terms first. An offer is never free money, and none of it is risk-free.

How often is this updated?

We refresh the comparison roughly once a month, and the date at the top of the page reflects the last proper review. Operators tweak their apps, games and offers regularly, so if something looks off compared with what you see on their site, trust the operator's live page.

A quick disclaimer. Game House Criteria is an independent comparison site, not an operator or a regulator, and it isn't owned by any of the brands listed. Everything here is for people aged 18 and over in Great Britain. Offers and features change often, so always check the operator's own site for the current terms. Gambling should be entertainment, not a way to make money — if it stops feeling that way, take a look at our responsible gambling page.
