Game providers
Online casinos rarely build their own games. They license titles from studios — each with different maths, themes and live-table technology. Knowing who supplies an operator tells you more than a banner count ever will.
Major slot studios
NetEnt(now part of Evolution) built franchises like Starburst and Gonzo's Quest that appear across most large UK lobbies. Their slots tend toward medium volatility and polished mobile layouts — you will find them at 888 Casino and Voodoo Dreams among others on our list.
Pragmatic Playships a high volume of new releases monthly, from classic fruit machines to feature-heavy video slots. FitzBet and Hollywoodbets lean on this catalogue heavily; MrQ carries a curated subset including Big Time Gaming titles licensed through Pragmatic's portfolio.
Play'n GO and Red Tiger(also under Evolution) fill out mid-to-large catalogues with distinct art styles. Red Tiger's daily jackpot network is a recognizable hook at brands that license the full suite.
Live casino studios
Evolution dominates UK live dealer play — blackjack, roulette, baccarat and game-show formats like Crazy Time stream from their studios. 888 Casino runs one of the deeper Evolution lobbies; smaller brands typically offer a core table set rather than the full game-show range.
Playtech and Pragmatic Play Live appear at some operators as secondary live feeds, but Evolution remains the benchmark most players encounter first.
Why it matters when comparing
Two sites can both claim thousands of games yet share eighty percent of the same studios. Check whether the franchises you prefer — Megaways mechanics, live roulette variants, jackpot networks — are actually listed before you deposit. Our homepage comparison ranks operators partly on this mix.
