Two casinos can advertise "hundreds of games" and offer almost the same library, because both license from the same studios. Once you recognise the names, you can tell at a glance whether an operator's catalogue is genuinely broad or just a reshuffle of the usual suspects.
Here are the studios that matter most across the operators on this site, and what each one is actually good at.
EvolutionLive casinoThe company that effectively defined modern live-dealer casino. When you sit at a live blackjack or roulette table at almost any UK operator, the odds are Evolution is running it. It also owns NetEnt and Red Tiger, so its reach into slots is bigger than the name suggests. Game shows like Crazy Time and Lightning Roulette are theirs too — the closest thing online casinos have to a signature format.NetEntSlotsA Swedish studio with a long back catalogue and a reputation for polish. Starburst and Gonzo's Quest are the titles most players recognise, and they still turn up on welcome-offer free spins because they're cheap to play and widely understood. Now part of the Evolution group, but the games keep their own identity. You'll see plenty of NetEnt at Voodoo Dreams and NYSpins.Pragmatic PlaySlots + liveOne of the most prolific studios of the last few years, releasing new slots at a pace few can match. The Wolf Gold and Gates of Olympus lines are everywhere, and it runs its own live-casino tables as an Evolution alternative. Its sheer output is why a Pragmatic logo shows up across nearly every operator on this site, Paddy Power and MrQ included.Play'n GOSlotsBest known for Book of Dead, a single slot that anchors a huge number of bonus offers. Play'n GO leans toward mechanically straightforward games with clear volatility, which makes them a common pick for free-spin promotions. They're a staple at the SuprNation brands and most slots-led sites.Light & WonderSlotsThe studio formerly trading as Scientific Games, bringing land-based casino titles to online play. If you've seen a game on a physical fruit machine and then found it on your phone, Light & Wonder is often the bridge. MrQ leans on its catalogue alongside Pragmatic. Why this matters when you compare
If you have a favourite slot, the practical question isn't "how many games does this casino have" — it's "does it carry the studio that made the one I like". A site stacked with NetEnt and Play'n GO, like the SuprNation pair, will feel very different from one built around in-house and Playtech titles, even if the game counts look similar.
It also explains the live casino overlap: because Evolution supplies so many operators, the live tables you find at one are frequently identical to another. We cover that directly on the live casino page.
