If you ever played a slot machine in a physical casino — anywhere in the world — chances are it was a Novomatic. The Austrian company operates 255,000 gaming terminals across more than 2,100 venues distributed in 50+ countries. They are the makers of the iconic Gaminator machines that dominate casino floors from Vienna to Buenos Aires.
Founded in 1980 by professor Johann F. Graf, Novomatic generates approximately $5 billion in annual revenue. It employs 24,000 people. And its online division, Greentube, brings to the digital world the classics that millions of players know from the land-based floors.
Book of Ra. Lucky Lady's Charm. Sizzling Hot. Lord of the Ocean. Names that, for land-based casino players, are as familiar as the lights and sounds of the machines where they first played them.

Greentube: 840 Employees Bringing the Classics Online
Greentube was founded in 1998 as an independent technology company. Novomatic acquired it in 2010 and turned it into its digital arm. Today Greentube employs ~840 people and manages a catalog of more than 400 online games, of which 360+ are slots.
Greentube's strategy is straightforward: take Novomatic's classics that worked for decades on physical machines and adapt them to HTML5 for play on any device. They do not reinvent the wheel. They move it to the internet.
That includes the migration of the NOVO LINE Interactive system, which keeps the original mechanics of the physical machines — the feel of spinning a Gaminator on your phone.
The 10 Classic Novomatic/Greentube Slots
| # | Slot | RTP | Volatility | Max Win | Note |
|---|---|---|---|---|---|
| 1 | Book of Ra Deluxe | 95.10% | High | 5,000x | The definitive classic |
| 2 | Lucky Lady's Charm Deluxe | 95.13% | Medium-High | 9,000x | Charm theme |
| 3 | Sizzling Hot Deluxe | 95.66% | Medium | 5,000x | Classic fruits |
| 4 | Lord of the Ocean | 95.10% | High | 5,000x | Ocean theme |
| 5 | Columbus Deluxe | 97.03% | Medium | 5,000x | Highest RTP in the catalog |
| 6 | Dolphin's Pearl Deluxe | 95.23% | Medium | 5,000x | Dolphin theme |
| 7 | Just Jewels Deluxe | 97.79% | Low | 5,000x | The most generous RTP |
| 8 | Book of Ra Deluxe 6 | 95.10% | High | 15,000x | 6 reels, triple max win |
| 9 | Faust | 95.12% | High | 5,000x | Literary theme |
| 10 | Pharaoh's Ring | 95.09% | Medium | 5,000x | Egyptian theme |
Novomatic's RTPs are consistently lower than those of Pragmatic Play or NetEnt. The 95.09-95.66% range (with exceptions such as Columbus at 97.03% and Just Jewels at 97.79%) reflects the land-based origin of these games — physical machines have historically operated with lower RTPs.
For online players who compare RTP: a Novomatic slot at 95.10% statistically returns less than Gates of Olympus at 96.50% or Starburst at 96.08%. The 1.4 percentage-point difference is felt over the long run.
But Novomatic players rarely choose by RTP. They choose for nostalgia, familiarity and the feel of playing what they know from the land-based casino.
Book of Ra: 7 Versions of an Immortal Classic
Book of Ra is the oldest slot franchise still active. The original version launched as a land-based machine. Since then, Novomatic/Greentube has produced 7 versions:
- Book of Ra Classic: the original, 5 reels, 9 lines
- Book of Ra Deluxe: improved graphics, 10 lines
- Book of Ra Deluxe 6: 6 reels, max win 15,000x (triple the Deluxe version)
- Book of Ra Magic: with an expanded symbol mechanic
- Book of Ra Jackpot Edition: with a progressive jackpot
- Book of Ra Temple of Gold: with an "Extra Bet" feature
- Book of Ra Deluxe 10: 10 lines with updated mechanics
The core mechanic stays the same in all of them: free spins with a random expanding symbol. The book is scatter and wild simultaneously. It is the formula that Play'n GO adapted for Book of Dead and that dozens of other providers have replicated in their own "Book of" slots.
From the Land-Based Casino to Online: 255,000 Gaminator Terminals
Novomatic's Gaminator terminals are the multigame machines you find in land-based casinos all over the world. Each terminal offers access to multiple Novomatic games from a single cabinet.
255,000 terminals in 2,100+ venues means Novomatic has a physical footprint that no purely online provider can match. Pragmatic Play has 500 online slots. Novomatic has 255,000 machines in real buildings.
That land-based base is the reason Book of Ra remains relevant 20+ years later. Players discover it in the casino in their city and then look for it online.
Presence in Mexico and Argentina
Mexico
- Crown Gaming Mexico: a Novomatic subsidiary with offices in Polanco, CDMX. It operates Gaminator machines in Mexican land-based casinos.
- Greentube online: available at Rushbet (verified as one of the lobby's 44 providers) under the name "Greentube."
Argentina
- Novomatic Argentina S.R.L.: an operation based in Buenos Aires. Presence in land-based casinos with Gaminator machines.
- Online: available at casinos that integrate the Greentube catalog.
Novomatic's presence in LatAm is predominantly land-based. The Greentube online catalog is available but its penetration in regulated Mexican and Argentine casinos is lower than that of Pragmatic Play or Evolution.
