Greentube is the online gaming arm of NOVOMATIC and they have some of the most recognisable slot titles in European casino history. Most players have probably heard of Book of Ra Deluxe even without playing it. We tested five UK-licensed Greentube casinos that carry their content and worked through ten of the studio’s best slots to see how the mechanics and RTP’s play out across different casinos.

Greentube started life back in 1998 with a ski racing game of all things, before the company was renamed Greentube Internet Entertainment Solutions AG in 2000 and eventually folded into the NOVOMATIC Group in 2010. Since then the business has expanded into online slots, table games, video bingo, video poker and social casino content.
Greentube’s UK regulatory position rests on two pieces of paperwork. The first is a Great Britain Remote Gambling Software licence sat with Greentube GmbH under a UKGC account, the second is active UKGC software and gaming machine technical licences sat with Greentube UK Limited. Both operate at supplier level rather than casino level, so they cover the development and distribution of the games rather than the casinos themselves.
All the casinos sitting on the list below are listed on the UKGC public register under licensed operators and carry Greentube or NOVOMATIC content alongside slots from other major providers. We picked these five out because they each confirmed Greentube titles in the lobby, along with enough overall game depth from other top providers that the Greentube options worked as part of a full casino rather than being the only thing on offer.
LuckyMate’s current welcome offer gives you 50 bonus spins on Big Bass Splash after depositing and wagering £10, which is a low entry point for testing out the lobby. The bonus does require a promo code which you can grab from the LuckyMate site before depositing. The game library has 1,700+ casino games with NOVOMATIC and Greentube content sitting alongside titles from other studios. LuckyMate works well as a starting point for players who want Greentube classics available inside a broader multi-provider casino rather than a specialist NOVOMATIC-only site.
7bet offers 100 bonus spins on Big Bass Splash after a £20 deposit and £20 slot bet, so the entry cost is higher than LuckyMate but you’re also getting double the spins. The site also runs a sportsbook alongside the casino, which is a plus if you want sports and slots under one login. What makes 7bet a strong Greentube pick is that the site has official game pages for titles like Book of Ra Deluxe and Lucky Lady’s Charm Deluxe. The wider slots section promotes 2,000+ games, but the classic Greentube titles are easy to find rather than buried in a massive unfiltered lobby.
Grand Ivy’s UK welcome offer gives you 75 free spins on Big Bass Bonanza after a first deposit of £20 and £10 slot bet. The overall game library has 3,000+ titles which puts it among the bigger lobbies in this group. The site has been running since 2016 so it’s had plenty of time to build out its provider partnerships. Greentube classics sit alongside content from dozens of other studios in the lobby, and the depth gives you the room to move between classic games and more modern releases without changing casinos.
Unibet is one of the biggest names in UK online gambling, so most players will likely already know what the site offers in terms of sports, casino and live dealer content. The game library sits at 1,000+ titles and the brand’s reputation is more well-known compared to some of the newer operators on this list. Unibet’s casino welcome offer gives new players 200 x £0.10 free spins on Big Bass Bonanza after opting in, depositing and staking £10 on slots. The Greentube connection here is particularly strong after Greentube announced that Kindred Group added their content to the UK-facing Unibet casino through the NRGS platform. That deal specifically brought classic NOVOMATIC titles into Unibet UK including Book of Ra Deluxe, Lucky Lady’s Charm Deluxe and Sizzling Hot Deluxe.
Mr Luck’s welcome offer is a deposit £20+ and bet £20 to get 20 Free Spins on Big Bass Splash with no wagering on winnings. The game library has 3,000+ titles which makes it one of the largest lobbies on this list covering slots, table games and live dealer content. The sheer size of the catalog alone is what separates Mr Luck from the other four, and with 3,000+ games you’re getting Greentube content included with a massive multi-provider library. There’s enough variety that you could spend an entire session on NOVOMATIC classics or branch out into completely different studios without leaving the site.
This list mixes the NOVOMATIC classics that built Greentube’s reputation with some of their newer Diamond Link jackpot releases. Just bear in mind that these RTP’s come from the public game data and slot databases but operator configurations can vary, so the in-game info panel is always the final figure.
Book of Ra Deluxe is the Greentube slot most people have heard of and for good reason. It uses a 5-reel, 10-line Egyptian adventure setup where the Book symbol acts as both Wild and Scatter. Landing three or more Books triggers 10 free spins and one symbol is randomly chosen to expand across the reels for the duration of the round. RTP is commonly listed around 95.10% and the game has been a staple of both land-based NOVOMATIC cabinets and UK online casino lobbies for years.
Lucky Lady’s Charm Deluxe takes a 5-reel, 10-line format and wraps it in charm symbols including horseshoes, clovers and ladybirds. RTP comes in at 95.13% with the main feature set covering Wild symbols, 15 free spins and tripled wins during the bonus round. The free spins multiplier is where most of the value sits, and the game runs at a more relaxed pace than some of the higher-volatility titles further down this list.
Sizzling Hot Deluxe is about as simple as an online slot gets. Five reels, 5 paylines, classic symbols like sevens and bells and fruit, and absolutely no free spins round. RTP is listed at 95.66% with medium volatility and the only extra feature is a gamble option after wins. This is the game you load when you want a stripped-back fruit machine session without any mechanical complexity getting in the way.
Diamond Link Mighty Elephant gives the Greentube catalog a more modern look with an African wildlife theme spread across 5 reels and 25 lines. RTP is 95% with medium volatility and the standout feature is the Diamond Link mechanic which can land one of four jackpot-style prizes. Free spins and respin-style bonuses make up the rest of the feature set, making this slot one of the most layered games in the Greentube lineup.
Diamond Link Mighty Sevens takes a traditional fruit-machine theme and bolts on the Diamond Link jackpot system. The setup is 5 reels and 25 lines with 95% RTP, and the features include Win Spins, Diamond Link mechanics and four jackpot-style prize tiers. It bridges the gap between Greentube’s classic fruit slot roots and the more modern jackpot-driven releases that dominate current casino lobbies.
Book of Ra Magic pushes the Book of Ra formula into higher volatility territory. The 5-reel 10-line structure is the same with the Book symbol still working as Wild and Scatter, but the max win climbs to around 10,056x on this version. That puts Book of Ra Magic among the more explosive games on the list. The high volatility is aimed at players who already know the Book of Ra format but want a version with higher potential wins to chase down.
Lord of the Ocean takes the theme away from desert treasure books and into a Poseidon-style underwater setting. The slot runs across a 5-reel, 10-line layout with Wilds, free games and a gamble feature. RTP comes is 95.1% with very high volatility and a max win around 5,000x. The underwater theme gives this slot a different visual identity from the rest of the Greentube catalog, and the volatility profile leads to longer sessions with bigger swings.
Dolphin’s Pearl Deluxe stays in the ocean with pearls, dolphins and treasure symbols across a 5-reel, 10-line setup. RTP is 95.13% with high volatility and a max win around 4,638x. Wilds, free spins, multipliers and a gamble feature make up the bonus mechanics, and the game shares a lot of structural DNA with Lucky Lady’s Charm Deluxe if you enjoy that style of play.
Columbus Deluxe has a seafaring discovery theme over 5 reels and 10 paylines, with Wilds, Scatters and a free spins round on the slot. The default RTP comes in at around 96.09% which is the highest RTP pick on this list by a comfortable margin, although lower configured versions exist at some operators. Volatility comes in at low-to-medium with a max win around 5,000x. Columbus Deluxe ends up sat among the better picks on the list for players who prefer steadier session pacing over high-variance spikes.
Queen Cleopatra rounds out the list with another Egyptian-themed Greentube slot built around a magical Book symbol and up to 10 win lines. The aim is landing five matching symbols across left-to-right win lines with the Book opening the way to a treasure-chamber feature. RTP is listed at 94.4% which is one of the lowest on this list.
UK players who like classic slot design with recognisable mechanics will find Greentube casinos work well for them. The studio’s biggest titles have familiar slot foundations like book symbols, fruit machines, charm themes, gamble features and free spins rounds rather than complex multi-layered bonus systems. You also have a layer of familiarity and trust with the NOVOMATIC connection because Greentube’s online slots run on the same mechanical DNA as land-based NOVOMATIC cabinets that have been running in casinos across Europe for decades.
