About Greentube
Greentube is anything but a new slot studio. The NOVOMATIC Digital Gaming and Entertainment division traces its roots back to 1998 and has grown into one of the industry’s better-known suppliers, combining online casino content with the enormous library of games associated with NOVOMATIC’s land-based gaming heritage.
The company became part of the NOVOMATIC Group in 2010 and now supplies slots, table games, bingo, video poker and other casino content across international markets.
For many players, though, Greentube is synonymous with a handful of classic titles. Book of Ra Deluxe, Lucky Lady’s Charm Deluxe and Sizzling Hot Deluxe remain some of its most recognisable games, giving the provider a particularly strong connection between traditional fruit-machine gaming and modern online slots.
In 2026, its catalogue now stretches far beyond those classics, with hundreds of games covering everything from ancient Egypt and mythology to fruits, animals and more feature-heavy modern releases.
Greentube’s mechanics have evolved considerably alongside its classic catalogue. Book of Ra Deluxe: Win Ways, for example, takes the familiar 5-reel formula and turns it into a six-reel, 117,649-ways-to-win game, adding cascading wins and expanding symbols during free spins. Other titles use Lock & Spin mechanics, jackpots, bonus rounds and more modern ways-to-win formats.
RTP varies substantially between individual games and configurations, so there’s no useful single “Greentube RTP”. Its older titles can sit below the 96% mark, while individual games and newer configurations can offer different settings.
In terms of distribution, the provider is licensed for regulated markets including Great Britain and Malta, with Greentube GmbH holding a UK Gambling Commission remote gambling software licence.
“Greentube is one of those providers where the classics really are classics. You can talk about flashy new mechanics all day, but Book of Ra and Sizzling Hot have a reason people still recognise them instantly.” Adam, Slots Reviewer
“What I like is seeing Greentube take those old-school games and actually do something different with them. Book of Ra Win Ways is the perfect example – it still feels like Book of Ra, but there’s a much more modern game beneath it.” Aisley L., Slots Streamer
