Greentube
Greentube GmbH is a Vienna-based gaming software studio and the digital gaming and entertainment division of Austria’s NOVOMATIC Group. The company traces its origin to 1998, when it began developing the 3D sports title Ski Challenge under the name Dürrschmid&Reisinger OEG. It was renamed Greentube Internet Entertainment Solutions AG in 2000, and in 2010 it became part of the NOVOMATIC Group.
Greentube’s core business is supplying slot, table, video poker, and video bingo games to licensed casino operators on a B2B basis. The studio’s product line also includes Greentube Plurius™, a server-based gaming system used for video lottery terminal (VLT) networks.
Beyond software supply, Greentube’s corporate group also directly owns and operates several consumer-facing casino and sportsbook brands in Europe, with a further acquisition announced for May 2026 (subject to regulatory approval). This is a distinct role from Greentube’s B2B game-supply business. CasinoHostNews does not name, link to, review, or recommend any operator brand tied to Greentube — this page covers Greentube strictly as a game studio.

Flagship Games & Style
Greentube’s slot portfolio is organized around recurring franchise mechanics rather than one-off titles — the Diamond Link Series and Diamond Mystery™ Series are recurring product lines, and Win Ways™ is used across multiple releases as a house mechanic. The studio also maintains a Piggy Prizes™ franchise and a Cash Connection™ line, both spanning several entries. This franchise-driven approach gives Greentube’s catalog a recognizable house style across new releases rather than depending on a single breakout title.
