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.
