Novomatic Slots at Admiral Casino
Book of Ra, Sizzling Hot, Lucky Lady's Charm. If you've spent time in a UK arcade, you know these games. Finding them online is a different story. Admiral Casino is one of the only places in the UK where you can play them legally.
There's a simple reason for that. Admiral IS Novomatic. The casino is run by Greentube Alderney Limited, a direct subsidiary of the Novomatic Group. So while other operators would need to negotiate licensing deals, Admiral just... has them.

I spent years watching Novomatic cabinets swallow coins in arcades before any of these games made it online. When Greentube finally launched Admiral Casino in the UK, the appeal was obvious: the exact same titles, playable from your sofa. This page breaks down every Novomatic slot available at Admiral, with the RTPs, volatility levels, and features that actually matter.

Why Admiral Has These Slots (And Nobody Else Does)
It's not a licensing deal. It's a family business.
Novomatic Group
One of Europe's biggest gaming companies. Founded in Austria in 1980. They manufacture slot machines, develop games through Greentube, and operate casinos worldwide. Revenue in the billions.
Greentube (The Developer)
Novomatic's digital arm. Greentube Alderney Limited is the entity that holds Admiral Casino's UKGC licence (39050). They convert the classic land-based Novomatic slots into online versions and distribute them.
Admiral Casino (The Shop Front)
The online casino and the 270+ physical Admiral Slots arcades across Britain. Because it's all under the Novomatic umbrella, Admiral gets first-party access to every Greentube title. No middleman.
The bottom line: When you search for Book of Ra at Bet365 or William Hill, you won't find it. Those casinos use providers like Playtech, Microgaming, and Evolution. Greentube has been selective about UK distribution, and Admiral is the primary outlet. If you want Novomatic online in the UK, this is where you go.
Novomatic Slot Spotlights
Every title below is available at Admiral Casino. RTPs are published figures from Greentube.
Book of Ra Deluxe
Most PopularThe slot that built Novomatic's reputation. Egyptian-themed with a mechanic that's been copied hundreds of times since: the expanding symbol during free spins. Land three Book symbols, pick a random icon, and that symbol expands to cover entire reels during your 10 free games. It's straightforward, it's volatile, and it's the reason people still walk into Admiral arcades.

Key features: Expanding symbols in free spins, gamble feature (double or nothing on any win), scatter pays. The 95.10% RTP is below today's average, but this game has never been about return — it's about the free spin trigger and what happens when the right symbol gets chosen.
Sizzling Hot Deluxe
ClassicAbout as stripped-back as a slot gets. Five reels, five paylines, fruit symbols. No free spins feature, no bonus round, no wilds. You spin, you match, you win or you don't. There's a gamble feature if you want to risk your wins, but that's it. Sounds boring on paper, but the simplicity is the draw. People who play Sizzling Hot know exactly what they're getting.

Key features: Gamble feature, scatter pays with the star symbol. The highest-paying symbol is the lucky 7. At 95.66% RTP it's actually the highest-returning Novomatic slot in Admiral's collection. No frills, just fruit.
Lucky Lady's Charm Deluxe
Fan FavouriteThis one's been a mainstay in European casinos for years. Luck-themed with a crystal ball scatter. The standout feature is the free spins round: 10 free games with a 3x multiplier on every win. That multiplier turns decent hits into proper payouts. You can also retrigger the free spins, which is where the bigger sessions come from.

Key features: 10 free spins with 3x multiplier, retriggerable free games, gamble feature, wild substitutions. The crystal ball is wild and scatter. Medium volatility makes it more forgiving than Book of Ra, with the 3x multiplier providing the upside.
Lord of the Ocean
Book MechanicIf you like Book of Ra's expanding symbol mechanic but want a different theme, this is it. Underwater Greek mythology setting, but the core gameplay is nearly identical: land three scatters, trigger 10 free spins, a random symbol expands. The trident acts as both wild and scatter. Think of it as Book of Ra with a fresh coat of paint and Poseidon instead of pharaohs.

Key features: Expanding symbol in free spins (same mechanic as Book of Ra), wild/scatter combo symbol, gamble feature. Same 95.10% RTP and high volatility profile. Popular with players who want the Book mechanic without replaying the same theme.
Columbus Deluxe
Explorer-themed slot based on Christopher Columbus. The ship symbol acts as the scatter, and three or more trigger 10 free spins. During free games, an additional wild symbol appears on reels 2, 3, and 4, which changes the maths considerably. It's a slightly different structure to the Book games — less reliant on a single expanding symbol, more on wild coverage.

Key features: 10 free spins with extra wilds on middle reels, gamble feature, scatter pays. The 95.02% RTP is the lowest in this list, but the extra-wild free spins mechanic gives it a different feel to the Book-style games.
Dolphin's Pearl Deluxe
Marine-themed slot with dolphins, seahorses, and treasure chests. The dolphin is wild and doubles all wins it completes. Three or more scatter symbols trigger 15 free spins with a 3x multiplier — that's five more free games than Lucky Lady's Charm, with the same multiplier. Retriggerable too. One of the better free spin rounds in the Novomatic catalogue.

Key features: 15 free spins with 3x multiplier, wild doubles wins, retriggerable free games, gamble feature. The combination of 15 spins (vs 10 on most Novomatic games) and the 3x multiplier makes this one of the more generous free spin setups in the range.
Novomatic Slots RTP Comparison
All RTPs are Greentube's published theoretical figures. Actual returns vary per session.
| Slot | RTP | Volatility | Paylines | Free Spins |
|---|---|---|---|---|
| Book of Ra Deluxe | 95.10% | High | 10 | 10 + expanding symbol |
| Sizzling Hot Deluxe | 95.66% | Medium | 5 | None |
| Lucky Lady's Charm Deluxe | 95.13% | Medium | 10 | 10 + 3x multiplier |
| Lord of the Ocean | 95.10% | High | 10 | 10 + expanding symbol |
| Columbus Deluxe | 95.02% | Medium-High | 10 | 10 + extra wilds |
| Dolphin's Pearl Deluxe | 95.13% | Medium | 10 | 15 + 3x multiplier |
A note on RTPs: These Novomatic slots sit between 95.02% and 95.66%, which is below the current industry average of roughly 96%. That's typical for games that originated as land-based cabinets — they were designed for physical machines with different economics. You're trading a fraction of a percent in return for games you literally can't find anywhere else online in the UK.
Why You Can't Find These Slots Elsewhere
I've checked the major UK casinos. Here's where things stand.
Casinos WITHOUT Novomatic Slots

Casinos WITH Novomatic Slots
- Admiral Casino — Full Greentube catalogue
Greentube does distribute to a handful of other operators in regulated European markets, but in the UK, Admiral is the primary destination for their full range. The corporate ownership connection makes the difference.
This isn't marketing spin. Go to any of those casinos and search for "Book of Ra" or "Sizzling Hot." You won't find them. Greentube has kept its UK online distribution tight, and Admiral benefits directly from that exclusivity.
Other Game Providers at Admiral Casino
Novomatic is the headline act, but there's more to the library
NetEnt
Starburst, Gonzo's Quest, Dead or Alive. The other major provider in Admiral's catalogue. Higher RTPs than Novomatic on average (96%+).
Pragmatic Play
Gates of Olympus, Sweet Bonanza, The Dog House. High-volatility modern slots. A good counterbalance to the classic Novomatic titles.
Blueprint Gaming
Fishin' Frenzy, Eye of Horus, Genie Jackpots. UK-focused developer with Megaways titles and classic themes.
Evolution
Live casino tables — roulette, blackjack, game shows. Limited selection compared to bigger casinos, but the essentials are covered.
The total library is around 600 games. That's smaller than Bet365 (2,000+) or 888 (1,500+), but the Novomatic exclusives make up for the narrower range if those are the games you want. Full games library breakdown →
