Pick the wrong site and you end up with 400 slots from 3 providers, a live lobby that closes at midnight, and RNG table games that haven't been updated since 2019. The game library is where the real difference between operators shows — and across the sites reviewed here, the gap is wider than most players expect.
Coral sits at the top of the pile for sheer volume, with 5,000 titles and 4,500 slots drawing from NetEnt, Pragmatic Play, Hacksaw Gaming, and Games Global. Betfred follows at 2,400 games, leaning heavily on Playtech's catalogue alongside Push Gaming and Yggdrasil. Pub Casino stocks around 2,000 titles (1,800 slots) with a tighter but well-curated selection from Play'n GO, ELK Studios, and Stakelogic. Betano and William Hill both sit closer to 1,000 titles — smaller libraries, but Betano compensates with 6 proprietary live tables and exclusive branded slots you won't find anywhere else.
Among the best online casinos reviewed here, live dealer coverage runs across all 5 operators, with Evolution powering the core lobbies at Betfred, William Hill, Coral, and Pub Casino. For punters searching among non GamStop sites for unfiltered table access, the provider mix matters as much as the headcount.

Slots
Coral's slot library is the most substantial among the casino sites not on Gamstop reviewed here — 4,500 titles covering Megaways mechanics, cluster-pay formats, and cascading reels from the likes of Hacksaw Gaming and Blueprint. Pub Casino takes a different approach: 1,800 slots, but Play'n GO and ELK Studios titles dominate, which skews the RTP profile upward compared to libraries padded with lower-margin filler.
Live Dealer
Evolution runs the live lobbies at Coral, William Hill, Betfred, and Pub Casino — which means Crazy Time, Lightning Roulette, and the full game-show suite are accessible across all 4. Betano breaks from the pack with 6 in-house live tables built around its football identity, a format you won't see replicated at UKGC competitors. Stake limits at Betfred's Playtech Live tables push to £10,000 on certain baccarat variants, well above what most mid-tier sites allow.
RNG Table Games
William Hill's RNG table section draws on IGT and WMS alongside NetEnt, giving it a broader range of blackjack variants than its slot count might suggest. Betfred's Playtech integration adds side-bet poker and multi-hand blackjack options that casual players rarely find bundled together. Demo mode is available across most RNG titles at all 5 operators, which lets you test the mechanics before staking real money.
Crash and Instant Win
Pub Casino's Slingo Originals range is the standout here — a format that sits between slots and bingo, with titles like Slingo Rainbow Riches and Slingo Starburst carrying RTPs around 95–96%. Pragmatic Play's Spaceman appears at Betano and Coral, running a provably fair multiplier mechanic with a theoretical RTP of 96.5%. These titles attract a different type of punter than traditional slots — faster rounds, lower session cost, and a skill-adjacent stop mechanic.
Sports Betting
Among UK casinos not on GamStop, Betfred and William Hill carry the deepest sports catalogues, with horse racing coverage that includes Best Odds Guaranteed, in-play markets, and Cash Out on accumulators. Coral's Football Super Series adds boosted odds on selected matches weekly, and its in-play section covers over 30 sports. Betano leans into football specifically — UEFA Euro sponsorship translates into dedicated match-day markets and same-game accumulator tools that outperform its rivals on that single sport.
For players assessing online casinos UK options by game depth alone, Coral's 5,000-title library is difficult to match. If software variety matters more than raw numbers, Betfred's 10-provider stack — spanning Yggdrasil, Push Gaming, IGT, and Red Tiger alongside the majors — offers more mechanical diversity than any single-provider-dominated rival. The best non GamStop casinos reviewed here cover every major category, but no 2 operators weight them the same way.
