UK casino studio comparisons | Kingdom Game Benchmarks

Kingdom Game Benchmarks is an independent comparison site. We are not a casino operator, regulator or brand owner — we review and compare licensed UK sites and may earn a commission when you follow a link.

Studio-led comparison

Five UK-licensed operators, judged mainly on which game studios they carry, how deep the live-dealer floor runs, and whether their lobbies surface titles worth your time. We have walked these platforms as players — not as marketers — and the match scores below reflect that lens.

Operators on our bench

Match percentages score how well each site fits a player who cares about studio variety and standout games — not who shouts the loudest about bonuses.

Grosvenor

Grosvenor carries its high-street casino rooms into a digital lobby where Evolution-powered live tables sit alongside a slots catalogue that leans on NetEnt, IGT and Pragmatic Play. The brand feels familiar if you have walked into one of their UK venues, and the live section is where it earns most of its points.

Paddy Power

Paddy Power Games folds casino into a wider Flutter Entertainment account, which means Playtech and Games Global titles share space with in-house exclusives you will not find on smaller white-label sites. The catalogue is sports-adjacent in tone rather than boutique, but the studio mix is genuinely broad.

FitzBet

FitzBet is a smaller UK-facing operator where the casino side shares a wallet with sports betting. You get a tighter slots line-up—mostly mainstream studios like Pragmatic Play and Blueprint—rather than the depth of a dedicated casino-first brand, which suits players who want a straightforward catalogue.

Sky Vegas

Sky Vegas is built around slots from NetEnt, Red Tiger and IGT with a clean lobby that mirrors the broader Sky betting ecosystem. Live casino exists but the site clearly prioritises reel games and daily free-spin style promotions over table depth.

Happy Tiger

Happy Tiger is a newer UK casino brand with a modest but curated slots selection from providers such as Pragmatic Play and Relax Gaming. Live dealer options are thinner than at Grosvenor or Paddy Power, yet the site is easy to navigate if you mainly want reel games without a cluttered lobby.

Head-to-head

Studio match-ups

We paired operators on the game-studio factors that matter most when you are choosing where to play — live depth, slots breadth, jackpot focus and how quickly a lobby makes sense.

Live studio depth

Grosvenor

91% match

Studios: Evolution, NetEnt, Pragmatic Play, IGT

Happy Tiger

72% match

Studios: Pragmatic Play, Relax Gaming, Blueprint

Grosvenor edges this round. Grosvenor runs a full Evolution suite with branded tables tied to its retail rooms. Happy Tiger offers live games but the selection is noticeably slimmer—fine for occasional play, not for someone who compares roulette variants.

Slots studio breadth

Paddy Power

88% match

Studios: Playtech, Games Global, Red Tiger, Blueprint

FitzBet

74% match

Studios: Pragmatic Play, Blueprint, Evolution

Paddy Power edges this round. Paddy Power pulls from Playtech and Games Global at scale, including progressive networks FitzBet does not carry. FitzBet covers the popular Pragmatic and Blueprint hits but stops well short of the same catalogue width.

Jackpot-focused reels

Sky Vegas

85% match

Studios: NetEnt, Red Tiger, IGT, Evolution

Grosvenor

91% match

Studios: Evolution, NetEnt, Pragmatic Play, IGT

Sky Vegas edges this round. Sky Vegas leans into Red Tiger Daily Jackpots and NetEnt classics where the lobby is arranged around big-reel titles. Grosvenor spreads jackpots across more studios without making them the centrepiece.

Ease for first-time players

Happy Tiger

72% match

Studios: Pragmatic Play, Relax Gaming, Blueprint

Paddy Power

88% match

Studios: Playtech, Games Global, Red Tiger, Blueprint

Happy Tiger edges this round. Happy Tiger's smaller lobby means fewer menus to learn on day one. Paddy Power offers more games but also more categories—better once you know what you want, slightly busier when you are still browsing.

Criteria

How each operator scores

Percentage match scores reflect studio breadth, live-table depth and how well the lobby surfaces standout titles — not bonus size or payout speed.

Methodology

How we compare operators

Scores come from hands-on checks: we verify UKGC licensing on the public register, browse slots and live lobbies, note which studios appear, and test mobile layouts. Match percentages weight studio breadth and live depth heavily because that is what changes day-to-day play — not headline bonus figures that shift every month.

Kingdom Game Benchmarks is funded through affiliate links. We list operators we believe are worth comparing; commission does not buy placement. When a site lacks a studio or live variant, we say so plainly.

Honesty note

Who this site is — and is not — for

Kingdom Game Benchmarks suits players who want to know which studios and live tables sit behind a UK licence before opening an account. If you only want the biggest welcome figure with no interest in game catalogues, a bonus aggregator will serve you better.

We are not for anyone under 18, anyone looking to recover losses through gambling, or anyone who needs help with an existing operator account — contact the operator or GamCare directly for that.

Questions

Common questions

Why do match scores differ from star ratings elsewhere?

Our percentages weight game studios and live-dealer depth for the five operators on this page. A site with a modest bonus but a full Evolution lobby can outscore a louder rival that leans on a thin slots catalogue — that is intentional, not an oversight.

Are these operators licensed in the UK?

Yes — every brand listed here holds a UK Gambling Commission licence or operates under a parent company that does. We cross-check the public register before adding an operator, and we remove any site that loses its licence. Playing at unlicensed sites forfeits the dispute and self-exclusion protections UK players are entitled to.

How do welcome offers affect your scores?

They do not move the match percentage much. We note offer type — deposit match, free spins, combined sports/casino — because wagering rules matter, but we will not rank a site higher purely for a larger headline number. Always read the T&Cs on the operator site before opting in.

Can I self-exclude from every site here at once?

GAMSTOP covers operators licensed for online gambling in Great Britain. Register at gamstop.co.uk and the block applies across participating brands for the period you choose. It is free and does not require contacting each casino individually.
