About Greentube

98 free demo games from Greentube available now.

Greentube is the Vienna-based digital gaming subsidiary of Novomatic, the Austrian land-based giant. Founded in 1998 and fully absorbed by Novomatic in 2010, Greentube is the vehicle that brings the famous Gaminator shop-floor library online — which means its catalogue overlaps heavily with the Novomatic hub on this site. If you've played a Novomatic machine in a German or Austrian arcade, the online version you find here is almost certainly a Greentube build.

The anchor is the Book of Ra series — Book of Ra Deluxe and Book of Ra Magic — the Egyptian expanding-symbol slot that predates and arguably defined the entire 'book' subgenre. Around it sit the classic fruit machines that fill Spielhallen across the German-speaking world: Sizzling Hot, Lucky Lady's Charm, Lord of the Ocean, Dolphin's Pearl and Faust. These are deliberately retro — sevens, bells, fruit, minimal animation — translated faithfully to browser rather than redesigned.

Greentube RTPs vary more than with modern studios: Novomatic titles ship in several configurations (typically 93% to 96%) and the operator chooses at integration, so always check each game's info panel rather than assuming. Demo builds are the deployed Greentube versions and behave identically to the real-money game minus any jackpot payout.

Notable titles
  • Book of Ra Deluxe — the original Egyptian book-slot
  • Sizzling Hot Deluxe — five-reel classic fruit slot
  • Lucky Lady's Charm Deluxe — four-leaf-clover classic
  • Lord of the Ocean — Poseidon-themed book-slot variant

Frequently asked questions

Are Greentube and Novomatic the same company?
Greentube is Novomatic's wholly-owned digital arm. Novomatic builds the land-based cabinets; Greentube publishes the online versions. The Book of Ra or Sizzling Hot you play online is a Greentube build of a Novomatic game — the two hubs on this site cover overlapping catalogues for that reason.
Why do Greentube RTPs vary so much?
Novomatic-origin slots are shipped in multiple RTP configurations (often 93% / 94% / 95% / 96%), and each casino picks one at integration. The figure you actually play is whatever the demo source published — check the in-game info screen before drawing conclusions from the hit rate.
Are these the same Greentube slots as on real-money casinos?
Yes. The demo build is identical to the real-money version — same RNG, same RTP, same volatility, same bonus features. Only the currency changes.
How many Greentube games do you have?
Currently 98 free demo titles from Greentube, updated weekly as new releases roll out.
Do I need an account to play?
No. Every game on this page loads instantly in your browser. We don't collect any personal data to let you play the demo.
Can I win real money?
No. All wins are in virtual credits and reset whenever you reload the game. Demo mode is for evaluation and entertainment only — to play for real money you'd need an account at a licensed online casino.
