Slot Providers & Studios

Big Time Gaming

5 slots

Big Time Gaming (BTG) is the Australian studio that invented the Megaways slot mechanic (a dynamic reel structure producing up to 117,649 ways to win on each spin, now licensed to dozens of other studios including Pragmatic Play, Blueprint, Red Tiger and Yggdrasil. BTG was acquired by Evolution in July 2021 for $471 million in cash plus a deferred payment structure tied to Megaways licensing revenue, validating the long-term value of the patent. The studio's own catalogue is small but high-impact: Bonanza Megaways (the original), Extra Chilli, White Rabbit, Lil Devil and Max Megaways. Their slots are characterised by extreme volatility, deep bonus rounds with multiplier mechanics and headline max-wins frequently above 50,000x. BTG holds UK Gambling Commission and Maltese licences. For UK players, BTG-developed Megaways titles tend to be the high-water-mark for the mechanic) heavier on volatility than the Megaways-licensed competitors that ship more accessible variants.

Blueprint Gaming

5 slots

Blueprint Gaming is a UK-headquartered slot studio (Newark, Nottinghamshire) acquired by Gauselmann Group in 2008. They are one of the most prolific Megaways licensees and the studio behind Fishin' Frenzy, the Genie Jackpots series, Eye of Horus and a long catalogue of branded slots tied to film, music and TV IP including The Goonies, Ted, Ren & Stimpy and Superman. Blueprint's UK roots show in their catalogue, many releases are tuned for the British retail betting market with stake structures and theming aimed at long-time fruit-machine players. The studio holds UK Gambling Commission and Alderney licences, and most of their catalogue is available at every UK-licensed operator. Blueprint's Megaways implementations are generally lower-volatility than Big Time Gaming's own titles, with Fishin' Frenzy Megaways and Buffalo Rising Megaways among the most-played slots in the UK regulated market over the last five years.

Evolution

5 slots

Evolution is the dominant live-dealer studio for UK-licensed online casinos, supplying live blackjack, roulette, baccarat and a portfolio of game-show formats (Lightning Roulette, Crazy Time, Monopoly Live, Funky Time, Crazy Coin Flip) to virtually every major UKGC operator. Founded in Stockholm in 2006 and now listed on the Nasdaq Stockholm exchange, Evolution acquired NetEnt in 2020 and Big Time Gaming in 2021, consolidating its position across both live and RNG verticals. Evolution operates studios in Latvia, Malta, the Netherlands, Spain, Georgia, Armenia, the United States and the Philippines, with dedicated UK-facing tables run from a London studio for several major UK operators. The studio is licensed by the UK Gambling Commission and audited by independent test houses including eCOGRA. For UK players, Evolution's live offer is effectively the default, no other supplier comes close on game-show formats or stream quality. Their RNG slot output via the NetEnt and Red Tiger labels remains substantial.

Hacksaw Gaming

4 slots

Hacksaw Gaming is a Maltese slot studio that listed on Nasdaq Stockholm in June 2025 at a valuation of approximately €2 billion. The studio shipped 44 new slots in 2025 and is best known for high-volatility mechanics, distinctive cartoon art direction and extreme max-win caps. Signature titles include Wanted Dead or a Wild, Stack 'em, Le Bandit, Cubes 2 and the RIP City series. Hacksaw operates a single-RTP transparency policy, every Hacksaw slot ships in one configuration only, listed publicly on their site, and operators cannot select a lower-paying variant. This is a deliberate point of differentiation from larger rivals and a meaningful one for UK players. The studio holds licences from the UK Gambling Commission, Malta Gaming Authority, the Greek HGC and several regional regulators. Hacksaw distributes through most major aggregators serving UK-licensed casinos and their full catalogue is available across mainstream operators. Their market position has shifted from boutique to mainstream over the last 24 months.

Microgaming

2 slots

Microgaming holds a place in iGaming history as the Isle of Man-based studio that built the first online casino software, launched in 1994. Their flagship slot, Mega Moolah, has paid more than £1.5 billion in jackpots since launching in 2006 and remains one of the most consistent multi-million-pound progressive networks in the regulated UK market. In 2022 Microgaming transitioned to a content aggregator model, distributing slots from a network of independent studios (Just For The Win, Stormcraft, Crazy Tooth, Snowborn) rather than developing in-house. The studio retains its UK Gambling Commission and Alderney Gambling Control Commission licences and continues to operate the Mega Moolah jackpot pool plus a handful of long-running tournament networks. UK players will encounter Microgaming branding most often through their continued progressive jackpot operation rather than new releases, though new content under the Microgaming brand still ships through partner studios.

NetEnt

8 slots

NetEnt is a Stockholm-founded slot studio (1996) now part of the Evolution group following the 2020 acquisition. They produced what became some of the most-played slots in the UK regulated market (Starburst, Gonzo's Quest, Dead or Alive, Twin Spin, Mega Fortune) and continue to ship around two new slots per month under the NetEnt and Red Tiger brands. NetEnt holds UK Gambling Commission, MGA, Romanian and Swedish licences and is one of the studios whose technical compliance and game-fairness standards are regularly cited by other regulators. Mega Fortune was for years the studio's headline progressive jackpot title, paying a record €17.8m in 2013, though the broader trend since the Evolution acquisition has been toward steady iteration on existing IP rather than groundbreaking new releases. Their live-game-show NetEnt Live has been folded into Evolution's wider live operation. UK players will find the full NetEnt catalogue at all major UKGC-licensed operators.

Nolimit City

7 slots

Nolimit City is a Maltese studio acquired by Evolution in July 2022 for €340 million, known for high-volatility slots with dark thematic art direction and headline-grabbing max-win caps that frequently exceed 100,000x. Their signature titles include the Tombstone series (Tombstone R.I.P. Deluxe, 2025, 96.05% RTP, 300,000x max), Mental and Mental 2 (2025, 96.13%, 99,999x max), Punk Rocker, San Quentin xWays and East Coast vs West Coast. The studio invented the xWays, xNudge and xSplit mechanics now found in their wider catalogue, all of which apply increasing multiplier stacking inside bonus rounds. Nolimit City holds UK Gambling Commission and Maltese licences, though several of their highest-volatility releases were modified before UK launch to comply with UKGC's bonus-buy restrictions. UK players see most of the Nolimit catalogue but with the bonus-buy feature disabled. The studio's mathematical extremity and art direction have built a small but devoted player base, while their max-win figures regularly attract significant streaming attention.

Play'n GO

5 slots

Play'n GO is a Swedish studio founded in 2005, headquartered in Vaxjö with offices in Malta and the UK, and one of the most widely distributed slot suppliers across UKGC-licensed operators. They are best known for Book of Dead (for several years the single most-played slot in the regulated UK market) alongside Reactoonz, Rise of Olympus and the Moon Princess series. The studio ships approximately five new slots per month and operates a deliberate strategy of mid-volatility mechanics with high replay value rather than chasing extreme max-win caps. Play'n GO holds licences from the UK Gambling Commission, Malta Gaming Authority, the Swedish Gambling Authority and several other major regulators. They have been a vocal advocate for technical-standard consolidation across European jurisdictions and were one of the first studios to publish detailed RTP transparency for all releases. UK players will find their full catalogue at virtually every UKGC-licensed operator.

Pragmatic Play

18 slots

Pragmatic Play is one of the most prolific and widely distributed studios serving UK-licensed online casinos. Founded in 2015 and headquartered in Malta, the studio ships between three and five new slots a month and has built a portfolio that spans video slots, bingo, virtual sports and a fast-growing live casino arm. UK players will recognise their flagship titles (Sweet Bonanza, Gates of Olympus, The Dog House, Big Bass Bonanza and the Megaways spin-offs licensed from Big Time Gaming. The studio is licensed by the UK Gambling Commission, the Malta Gaming Authority, the Romanian National Gambling Office and several other regulators globally. A point of caution for UK players: Pragmatic frequently ships multi-RTP variants of the same slot) typically 96.5%, 95.5% and 94.5% configurations, and the operator chooses which to load. Always check the in-game help screen for the configured RTP at the casino you're playing at. Pragmatic Play Live, the studio's live dealer arm, has expanded rapidly in the last two years and now competes with Evolution on game-show formats.

Push Gaming

6 slots

Push Gaming is a UK-founded studio (London, 2010) acquired by Evoke (formerly 888 Holdings) in October 2024 for €105 million. Best known for Jammin' Jars, Razor Shark, Razor Returns and Wild Swarm, Push has built a reputation for cluster-pays mechanics, sticky multipliers and accessible mid-volatility play that translates well to mobile. The studio ships roughly one new release per month and holds UK Gambling Commission, Maltese, Swedish and Romanian licences. Their catalogue is available at virtually all UK-licensed operators, though the Evoke acquisition has surfaced commercial questions about whether competing operators will continue to carry new releases at the same speed. Push are notable for relatively transparent RTP disclosure (most slots ship in a single 96%-and-above configuration) and for cluster-pays implementations that compete favourably with NetEnt's older Aloha! Cluster Pays format.

Yggdrasil

0 slots

Yggdrasil is a Maltese studio (Sliema, founded 2013) known for visually distinctive slots, a strong mythology theme catalogue and the GATI promotional engine that powers in-game tournaments at participating UK-licensed operators. Their flagship titles include Vikings Go Berzerk, Valley of the Gods, Hades Gigablox and the Multifly series. Yggdrasil is a Megaways licensee and operates its own GigaBlox proprietary mechanic, a mathematically distinct approach producing 8x8 reel structures with high-multiplier potential. The studio holds UK Gambling Commission, Maltese, Romanian and Swedish licences. Yggdrasil's commercial proposition leans heavily on its YG Masters partnership programme, where independent studios (Reflex Gaming, Reel Play, ReelPlay) ship through the Yggdrasil platform with shared promotional tooling. UK players will encounter the full Yggdrasil first-party catalogue at most major operators, plus a meaningful slice of the YG Masters partner catalogue.
