Progress Play is a specialist B2B casino platform provider set up in 2012 and which now offers gaming content from a wide variety of studios. Platform providers are responsible for distributing games on behalf of studios, and act as a sort of middleman between game developers and casino operators (you might also see them referred to as games aggregators).
