Novomatic Online Casinos List - Best Novomatic Casino Sites for 2026

What Novomatic Makes

Johann Graf started out in 1974 importing Belgian pinball machines through a company called Brodnik & Graf. When his partner left in 1980, Graf founded Novomatic and began manufacturing gaming machines under the Admiral brand.

Titles like Book of Ra, Sizzling Hot, and Lord of the Ocean started as physical cabinets on European casino and arcade floors, some dating back to the mid-2000s, before Novomatic brought its online arm in-house.

In 2010, Novomatic acquired a majority stake in Greentube, a Vienna-based studio that had released a 3D game called Ski Challenge in 1998, and folded it in fully by 2011. 

Greentube is now the actual publisher of Novomatic’s online library, holding the UKGC and MGA licenses that let those cabinet classics run in a browser.

How to Pick the Right Novomatic Casino

Novomatic’s library is old enough, and its distribution is split between two company names, so the usual checks matter more than they would with a newer studio.

• Greentube vs. Novomatic branding. Some casino pages list the studio as Novomatic, others as Greentube. They’re the same lineup, so check both names before assuming a site doesn’t carry it;
• RTP configuration. Several titles ship in more than one RTP version. A casino that shows which one is live is worth more trust than one that doesn’t say;
• Title depth. Some sites carry only Book of Ra, Sizzling Hot, and Lady Lucky Charm. Check Novomatic’s full game library if you want the full range of cabinet classics;
• Regional availability. Novomatic’s strongest coverage has historically been in Germany, Austria, Switzerland, and Central and Eastern Europe. If you’re outside that region, check the availability before you get attached to a title.

Where Novomatic Games are Available

Novomatic’s online reach follows its land-based footprint more closely than studios with a similar background. The company runs roughly 2,000 gaming venues across about 50 countries, and that regional concentration carries over into where Greentube’s online licenses apply.

Germany, Austria, and Switzerland remain the strongest markets for the online range, alongside a wide spread across Central and Eastern Europe, where the physical cabinets have run for decades. 

UK coverage exists through Greentube’s own UKGC license and through Novomatic’s Admiral Casino brand, but the wider library isn’t guaranteed on every UK-facing site. 

The Book of Ra Mechanic Explained

Book of Ra, Lord of the Ocean, Dolphin’s Pearl, and Lucky Lady’s Charm all share the same core trick: a designated special symbol during the free spins round expands to cover an entire reel, and if it lands enough times, it can fill the whole screen.

That’s what turns a quiet base game into a big win, and it’s the reason these titles still get compared to each other despite having different themes.

This isn’t a mechanic Novomatic invented in isolation; expanding wilds exist across the industry, but the specific “Book of” template built around it is distinctly Novomatic’s, and it’s been widely imitated by other studios since.

RTP Settings and Why They Vary by Casino

Novomatic’s library has one of the more pronounced land-based-to-online RTP gaps. The original Book of Ra had a 92.13% RTP on physical cabinets. The online Deluxe version pushed that to 95.10%, and some casino configurations run it as high as 95.50%.

This difference exists because land-based machines and online builds have historically been treated as separate products, configured for different regulatory environments and payout expectations. 

The operator picks which online configuration goes live, not the player, so the number you’re getting depends on the casino. The fastest way to check is the game’s info panel, usually reached through an “i” icon near the bet controls. 

Bonus Rules That Apply to Novomatic Games

Wagering contribution rates vary by casino and the specific game listed, so check the bonus terms like accepted titles, wagering requirements, and max cashout before assuming the industry standard.

Because so much of Novomatic’s lineup runs on the same “Book of” template, some casinos exclude the entire family from bonus wagering rather than each title separately. If Book of Ra is excluded, check if Lord of the Ocean and Dolphin’s Pearl are too, since they’re often bundled together.

A free spins offer built specifically around one of these titles is less common, but I’ve seen and even claimed some. Still, you shouldn’t expect those offers to be as numerous as for a newer studio actively marketing itself.

Should You Play Novomatic’s Cabinet Classics?

Novomatic casinos suit players who played the cabinet versions of their games, or who like the specific expanding-symbol format Book of Ra popularized over the modern, feature-stacked slots.

The Novomatic/Greentube naming split is worth remembering more than almost anything else on this page, since it’s the detail most likely to make you think a casino doesn’t carry a title it actually does.
