Jack Henshaw is the head writer and editor of Slot Providers, where every review of the studios behind the UK's online slots — from giants like NetEnt, Pragmatic Play and IGT to the one-hit boutiques — passes across his desk before publication.

Jack grew up in Nottingham, where a Saturday job changing tubes and clearing hoppers in a family-run bingo hall gave him his first look at the machinery of the gambling industry — literally. He went on to read Mathematics at the University of Sheffield, graduating with a BSc (Hons); his final-year project on pseudo-random number generation turned out to be a better career move than he realised at the time, because understanding how an RNG actually works is still the fastest way to cut through a game studio's marketing copy.

His first job out of university was in quality assurance at a games development studio, running the maths models of new slot releases against their published paytables and filing the compliance paperwork that goes with UKGC and MGA certification. From there he moved to the platform side, working for an aggregator that integrated dozens of providers' game feeds into UK casino sites — a job that meant reading every studio's technical documentation, release schedules and RTP configurations for a living. When he eventually crossed over into publishing, first as a data-led games reviewer and later as a content lead for several UK comparison sites, he brought that insider's toolkit with him. Slot Providers is the site he'd been sketching in notebooks for years: one place that treats the developers, not the casinos, as the story.

Fifteen years in and around the industry have hardened one conviction: a provider should be judged on its maths sheets, its certification record and its consistency — never on its showreel. Every profile he publishes checks the studio's licensing and testing-house certificates, verifies RTP figures against official game sheets, and flags when a title ships in multiple RTP builds so readers know exactly which version their casino is running. Release dates and ownership histories are confirmed against at least two independent sources, because studios get bought, merged and renamed constantly, and yesterday's fact is today's error.

Away from the site, Jack answers reader corrections personally, writes about safer gambling, and maintains a spreadsheet of every RTP variant he's ever documented — currently north of four thousand rows and growing. If you spot a mistake on any page, he genuinely wants to know: the contact form reaches him directly.

Our verdict: 7/10. This Inspired Entertainment review covers the best Inspired slots ranked, the retail-to-online journey, and the full licence file.

Thunderkick Slots & Where to Play in the UK (2026)

Thunderkick is the studio a handful of NetEnt defectors built in 2012 Stockholm on a simple bet: art direction could be the whole pitch. Independent, self-funded and still led by CEO Jan Lunde, it produced Esqueleto Explosivo’s cascading skeletons and the psychedelic Pink Elephants line without ever chasing the volatility studios’ arms race. Our verdict: 8/10. This Thunderkick review covers the best Thunderkick slots ranked, the six franchises that define the catalogue, and the full licence file.

Greentube Slots: Where to Play Book of Ra in the UK

Greentube is the digital arm of an Austrian arcade empire so large it barely needs online slots to matter: Novomatic, founded by Johann Graf in 1980, now runs 2,000+ gaming venues (many under the Admiral brand) across 50 countries. Greentube’s own 1998 Vienna start-up gave that empire its online voice — and gave the whole industry Book of Ra, the game that invented the “Book” genre every provider on this site now ships a version of. Our verdict: 7.5/10. This Greentube review covers the best Greentube slots ranked, the genre Book of Ra founded, and the full licence file.

IGT Slots: Where to Play Cleopatra & the Classics

IGT is the company that invented the modern jackpot: Si Redd’s 1975 Reno startup built the first wide-area progressive (Megabucks, whose $39.7 million strike remains slots’ biggest ever), the most successful slot brand in history (Wheel of Fortune) and the eternal Cleopatra. Since July 2025 its gaming arm has been fused with Everi under Apollo’s $6.3 billion deal — private again, Vegas-headquartered, still called IGT. Our verdict: 8/10. This IGT review covers the best IGT slots ranked, fifty years of jackpot history, and the full licence file.
