Novomatic

Novomatic AG was founded in Austria in 1980 by Johann Graf and grew to become Europe's largest land-based gaming machine manufacturer before entering online casino software. The company's Book of Ra — originally a physical reel slot — became the most played online slot in Austria, Germany, and Eastern Europe after its online adaptation, spawning 30+ Book of Ra variants across operators globally. Novomatic operates 29,000+ gaming terminals across its own casino properties and distributes 200,000+ machines to 100+ countries. Its online division produces Sizzling Hot, Dolphin's Pearl, and Lucky Lady's Charm alongside the Book series. Novomatic's Greentube subsidiary handles online gaming product development and has released Novomatic classics as HTML5 games compatible with modern online casinos.
