Slot providers: the studios behind GB casino games
The studios behind the slots and live tables at GB-licensed casinos, how their licences work and which casinos list them.
Slot providers are the studios that design, certify and host the games you see in a casino lobby: the casino runs the account and the cashier, while the provider supplies the reels, the maths and often the server the game runs on. In Great Britain every one of them needs its own Gambling Commission licence, separate from the operator's. This guide covers the eight studios whose names come up most in GB lobbies, what each is known for and how to check the details yourself.

What a game studio actually does for a casino
An online casino rarely builds its own slots. It signs content deals with studios, plugs their games into its site through an aggregator or a direct connection,. The studio decides almost everything about how a game plays: the number of reels and rows, how wins are counted, which bonus rounds exist, how volatile the game is and which RTP versions are available. The casino decides which games to carry, which RTP version to switch on where a choice exists, and whether a game counts towards a bonus.
That split explains why the same slot can look identical at two casinos and still differ in one important number. Several studios ship games in more than one RTP setting and let the operator choose. Hacksaw Gaming, for example, lists four settings for Wanted Dead or a Wild. The figure that applies to you is the one in the game's information screen at the casino where you play, not the one quoted in a video or on a review aggregator. Our guide to what RTP means explains why that matters over a long session.
Licences: studios sit on the register too
Anyone supplying gambling software to British players must hold a remote gambling software licence from the Gambling Commission (UKGC). Studios that also run games on their own servers for casinos usually hold a game host licence as well. Neither lets a studio take bets from you directly: that is the job of the operator's remote casino licence. Playtech is an exception worth knowing, as its account also lists remote casino, bingo and betting activities alongside software.
Some well-known studios do not appear on the register under their own names because they belong to a group. NetEnt and Big Time Gaming are both owned by Evolution, and the register shows no entry under either name; the group holds a GB licence through Evolution Malta Holding Limited. Nolimit City, another Evolution studio, surrendered its GB licence on 25 October 2026, so it is not covered here. You can search any studio or casino yourself on the public register; our guide on checking a licence walks through what each field means.
The eight providers covered in this guide
| Provider | GB register entry | Best known for |
|---|---|---|
| Pragmatic Play | Pragmatic Play (Gibraltar) Limited, account 56015 | Gates of Olympus, Sweet Bonanza, Sugar Rush and the Big Bass series; also live casino and bingo hosting |
| Hacksaw Gaming | HGMT Limited, account 54059 | Slots, scratchcards and instant-win games on its own game server |
| NetEnt | No entry under the NetEnt name; group licence held by Evolution | Starburst, Gonzo's Quest and the Avalanche cascading reels |
| Play'n GO | Play'n GO Malta Limited, account 55949 | Book of Dead, the Rich Wilde series, Reactoonz and Rise of Olympus |
| Evolution | Evolution Malta Holding Limited, account 41655 | Live dealer tables and live game shows such as Crazy Time |
| Blueprint Gaming | Blueprint Gaming Limited, account 6516 | Fishin' Frenzy, Jackpot King and film and TV branded slots |
| Playtech | Playtech Plc, account 38516 | Age of the Gods jackpots, branded slots and live casino |
| Big Time Gaming | No entry under its own name; group licence held by Evolution | The Megaways mechanic, first used in Bonanza |
The list is not a ranking. It reflects the studios that GB operators most often name in their own lobby and help pages, and the ones British players search for by name.
Which casinos carry which studios
Operators publish their studio line-ups in lobby filters and help pages, and these change as content deals come and go. From the operators' own pages: Amazon Slots lists Pragmatic Play, Blueprint Gaming, NetEnt, Play'n GO, Playtech, Games Global and Light & Wonder among others; LuckyMate names thirteen studios including Evolution, Playtech, NetEnt and Red Tiger; Pub Casino lists NetEnt, Pragmatic Play, Play'n GO, Evolution and Blueprint Gaming; Bella Casino lists Pragmatic Play, Playtech, Blueprint Gaming, Eyecon, Games Global and Play'n GO. Mecca Games groups its lobby into studio sections for Playtech, Blueprint and Eyecon, and Magical Vegas names NetEnt, Microgaming, IGT, Play'n GO, Scientific Games and Eyecon.
Live casino is often a separate list. Virgin Bet names Evolution, Pragmatic Live and Playtech for its live tables, and Hollywoodbets lists Evolution and Pragmatic Play among its suppliers. At the other end, Tombola Arcade states that its games are made in-house only, so you will not find any of the studios on this page there.
If a particular game matters to you, search for it in the casino's lobby before you deposit rather than relying on the provider list: carrying a studio does not mean carrying its whole catalogue.
What stays the same whoever made the game
British rules apply at game level, so they cover every studio equally. Online slots at GB-licensed casinos have a maximum stake of £5 per spin, or £2 if you are 18-24, under rules in force since 9 April and 21 May 2025. Autoplay, turbo and slam-stop features are banned, a slot spin must last at least 2.5 seconds, and the game has to show your net position and time played. A studio's international marketing may show features that do not exist in the British build, which is one more reason to judge a game by the version in front of you. More on the limits in our stake limits guide.
Bonuses are the casino's, not the studio's. When a welcome offer gives spins on a named game, the significant terms belong to the operator, and wagering on bonus funds is capped at 10x under GB rules from 19 January 2026.
Demo versions and age checks
Most studios publish demo versions of their games, and many GB casinos offer a demo mode. Since 7 May 2019 GB-licensed sites must verify your age before you can deposit or play demo games, so a casino demo needs a verified account. This site does not host playable demos; each provider page explains where the official ones live.

Questions readers ask
What is a slot provider?
The studio that designs the game, sets its maths and features and usually hosts it on its own server. The casino you play at is a different company that runs your account and the cashier.
Do slot providers need a UK licence?
Yes. Any business supplying gambling software to players in Great Britain needs a gambling software licence from the Gambling Commission. Studios owned by a group may be covered by the group's licence rather than an entry under their own name.
Does the provider decide the RTP I get?
Partly. The provider builds the game and may offer several RTP settings; the casino chooses which one to run. Check the figure in the game's information screen where you play.
Why can I not find a particular studio at my casino?
Casinos choose their own content deals, and some, such as Tombola Arcade, use in-house games only. Search the lobby for the game itself, as carrying a studio does not mean carrying every title.
