Fifteen studios that make online casino games, recorded only from their own published pages and the Gambling Commission register: entities, licences, certification wording, each dated 18 September 2026.
A method for confirming the studio credited on a casino game, separating brand from legal entity, and checking the licence and testing records that actually apply.
No document ranks casino games by how rigged they are. The GB licensing papers establish something narrower and more useful: a licensed game must publish its rules and its house edge, and settle by them. Read field by field.
Follow a return-to-player claim from a dated supplier statement to the rules for one game version, without treating a catalogue range as a live operator setting.
A useful studio profile answers a narrow question: who publishes this game, what entity is named in the documentation, and when was that information current?
No UK regulator ranks slot studios. The Gambling Commission lists 14 approved test houses and sets the fields every game test report must name, both read 23 September 2026.
No document read names one and this ledger does not rank games; RTS 3C requires each game’s house edge or RTP to be published before the bet, and the reader compares those.
Which companies develop live casino games with real dealers?
The register has no live-dealer field; the three entries read each hold Game Host (Casino) (Remote), and whether a game is live-dealt is on the studio’s page.
