Slot Briefcase is an independent comparison site — not a casino operator, not a regulator, and not owned by any brand we list. We review licensed UK operators and may earn affiliate commission when you follow outbound links.

Compare UK casinos by live games and slots.

We score five licensed operators on game range, live-dealer depth, mobile quality and studio partnerships — so you can see where each brand actually stands before opening an account.

Grosvenor logo

Grosvenor

Grosvenor bridges its high-street casino rooms with a solid online live-dealer floor — Evolution and Playtech tables sit alongside a slots lobby that leans toward mainstream titles rather than obscure indies. The app mirrors the desktop catalogue closely, which helps if you already know the brand from a local venue.

888 Casino logo

888 Casino

888 has been on the UK market since the early 2000s and still runs one of the deeper slot catalogues here — Pragmatic, Play'n GO and Red Tiger all feature, plus an in-house studio for exclusive titles. Live casino coverage is broad, with multiple roulette and blackjack variants that suit both low-stake testers and regular table players.

10Bet logo

10Bet

10Bet started life as a sportsbook and the casino section still feels secondary — slots are there, but the count is modest compared with dedicated casino brands. Live tables exist and run smoothly, though the selection is narrower; it suits someone who wants a single account for football coupons and occasional roulette rather than a slots-first experience.

MrQ logo

MrQ

MrQ built its reputation on wager-free spins rather than bloated match bonuses — the game list is smaller than 888 or Grosvenor, but every title is playable on mobile without friction. Live casino is present but not the main draw; slots from Blueprint, Pragmatic and a handful of others make up most of the catalogue.

Casushi logo

Casushi

Casushi wraps a standard UKGC-licensed casino in a playful sushi theme — beneath the branding sits a respectable mix of NetEnt, Microgaming and Big Time Gaming slots, plus a live lobby that covers the usual blackjack and roulette staples. It is a mid-weight option: more variety than MrQ, less depth than 888, with a site layout that keeps game categories easy to scan.

Themed picks

Where each operator leads

Best for live casino

Live-dealer depth matters if you prefer real tables over RNG roulette. These operators run the strongest live floors in our current lineup.

  • 888 Casino888 pairs a wide Evolution catalogue with consistent stream quality and enough table limits to suit casual and regular players.
  • GrosvenorGrosvenor's live lobby reflects its retail heritage — blackjack and roulette variants are well stocked, with game-show titles available.
  • CasushiCasushi covers the core live staples cleanly; not the deepest floor, but reliable for standard blackjack and roulette sessions.

Best for mobile play

Mobile performance covers load times, touch-friendly lobbies and whether live tables work on a phone without workarounds.

  • MrQMrQ is built phone-first — navigation stays simple, and the smaller catalogue actually loads faster on mid-range devices.
  • 888 Casino888's native apps carry most of the desktop library, including live casino, with stable streaming on mobile data.
  • 10Bet10Bet's unified sports-and-casino app suits users who switch between match betting and a few spins in one session.

Best for newcomers

First-time players benefit from clear layouts, straightforward registration and bonus terms that are easy to locate before depositing.

  • CasushiCasushi groups games by type with plain labels — finding slots versus live tables takes seconds, which reduces early confusion.
  • MrQMrQ's wager-free spin model avoids the steepest learning curve around playthrough requirements on welcome offers.
  • GrosvenorGrosvenor's familiar high-street name gives context, and the site surfaces responsible-gambling tools during signup.

How we compare

Our scoring approach

Match scores on this page weight game variety and live casino strength most heavily — that is the editorial spine of Slot Briefcase. Each operator earns a percentage based on how well it meets eight checkable criteria, from UKGC licensing through to mobile usability.

We visit lobbies, count live-table providers, test mobile layouts and read welcome-offer terms. Affiliate relationships fund the site but do not override these ratings — a partner cannot buy a higher game-range score. When a brand changes its catalogue or bonus structure, we update the figures and the last-reviewed date at the top of the page.

Common questions

FAQ

Safety

Are the casinos listed here licensed in the UK?

Every operator on Slot Briefcase holds a UK Gambling Commission licence for the services we compare. We check the public register before adding a brand and note if a licence status changes. Playing at unlicensed sites removes the dispute and self-exclusion protections UK players are entitled to.

How does GamStop work if I want to step back?

GamStop is a free UK service that blocks your access to participating online gambling sites for a period you choose — six months, one year or five years. Registration is at gamstop.co.uk and covers operators licensed in Great Britain. It is separate from individual site limits and applies across the network, not just one brand.

Can Slot Briefcase help with a dispute on my account?

No — we are an independent comparison site, not the operator. Account issues, verification delays or bonus queries go directly to the casino's support team. If you cannot resolve a complaint, the UK Gambling Commission lists approved alternative dispute resolution bodies for licensed firms.

Bonuses

What does a welcome offer actually involve?

Most UK welcome packages combine a deposit match, free spins or both, with wagering requirements attached. A 100% match up to £100 means the site adds bonus funds equal to your deposit, capped at £100 — but you must wager the bonus (and sometimes the deposit) a set number of times before withdrawing winnings. Always read the full terms on the operator's site before opting in.

Why do some sites highlight wager-free spins?

Wager-free spins pay winnings as cash rather than bonus credit, which removes the playthrough step on those winnings. The trade-off is usually a smaller spin count or lower spin value compared with heavily matched deposit bonuses. MrQ is the clearest example in our lineup; others follow traditional wagering models.

Does Slot Briefcase earn money from these links?

Yes. Outbound links to operators may carry affiliate tracking. If you register through one, we may receive a commission at no extra cost to you. That funding keeps the comparisons free to read, but it does not change how we score game range, live casino depth or mobile quality — those ratings come from our review criteria, not commercial deals.
