Best Novomatic Slots

The best Novomatic slots have shaped European casino gaming for over four decades. From Book of Ra launching the entire “Book of” genre to a deep catalogue of fruit-machine classics that still anchor Greentube’s portfolio today, the depth and durability of the Novomatic library are unmatched among legacy slot providers. The games below were chosen from across the Novomatic and Greentube online catalogue, with bonus mechanics and game structure verified against the developer’s own materials wherever Greentube discloses them, using the same approach we apply across all slot software providers.

Best Novomatic Slots: Quick Comparison

A Note on Novomatic vs Greentube

Before the rankings, one piece of context that matters for anyone playing these slots online. Novomatic is the Austrian parent company, founded in 1980 and best known for manufacturing land-based slot cabinets across more than 50 countries. Greentube is Novomatic’s digital gaming and entertainment division. Every Novomatic slot available at online casinos is developed and distributed by Greentube. Throughout this page, references to “Novomatic slots” and “Greentube slots” describe the same online catalogue.

A second piece of context: Greentube and Novomatic publish very limited specification data on their corporate sites. Game page specs like RTP, max win, and volatility are not consistently disclosed at the brand source. Where this page lists those figures, they reflect what Greentube has published in press releases and product brochures. Where the brand source does not publish a value, the entry is marked accordingly rather than carrying figures from third-party aggregators.

Gangster Paradise

• Theme: 1920s American gangsters
• Best Feature: Stacked Wilds and Free Spins
• Progressive: No

Gangster Paradise is a Greentube slot built around the 1920s American gangster theme, with Tommy guns, getaway cars, suited mob figures, and a gangster’s moll set against a moody jazz soundtrack. The reels are presented in a city-skyline backdrop with a strong Chicago noir aesthetic.

The mechanic centres on stacked wilds and a free games feature. The Wild symbol substitutes for all regular symbols to complete winning combinations, and symbols can land stacked on the reels. The Police Badge acts as the scatter, triggering the free games bonus when enough scatters land on the reels in a single spin. Stacked wilds carry into the bonus round, where full-reel wild stacks become the route to the slot’s biggest payouts.

A gamble feature is available after winning spins. Players can risk their payout on a card-colour double-or-nothing guess, with correct calls doubling the win and incorrect calls forfeiting it. Like most Greentube titles, the gamble can be played for several consecutive rounds before the win is locked in. RTP and max win figures are not published on the developer’s brand pages, so check the in-game paytable at your casino before playing to confirm the active settings.

Jackpot Diamonds

• Theme: Classic gems and diamonds
• Best Feature: Diamond Mystery Four-Tier Jackpot
• Progressive: No (Fixed Jackpot)

Jackpot Diamonds is part of Greentube’s Diamond Mystery slot series, which the developer describes as classic Greentube slot titles reworked and revamped with a four-level Diamond Mystery Jackpot. According to Greentube’s own product page for the series, Diamond Mystery slots give players the chance to win up to 5,000 times their stake, with values varying from slot to slot.

The presentation is deliberately stripped back, with classic gem icons and lucky 7s leading the paytable against a dark background designed to highlight the jackpot animations. The Diamond Mystery jackpot pick game is the headline mechanic. When triggered, players are taken to a pick screen where they reveal symbols, with matching combinations awarding the corresponding fixed jackpot tier.

A gamble feature is available after winning spins, in line with the standard Greentube pattern. Specific RTP and grid configuration values are not published on the developer’s brand pages.

Wild West

• Theme: American Wild West
• Best Feature: Multi-Reel-Set Architecture
• Progressive: No

Wild West is one of the more architecturally distinctive titles in the Greentube catalogue, with a Western theme set against a saloon aesthetic and traditional symbols including playing cards, sheriff stars, and outlaw portraits. The slot is part of Greentube’s classic Novomatic-developed catalogue from the company’s land-based heritage.

The base game runs the standard Greentube wild and scatter symbol structure, with free games triggered by the scatter symbol landing on the reels. Specific architectural details, RTP, and max win figures are not published on the developer’s brand pages, so verify in-game paytable values at your chosen casino before playing.

A gamble feature is available after winning spins, following the standard Greentube convention.

Faust

• Theme: Goethe’s German philosophical drama
• Best Feature: Mephistopheles Wild-Scatter Hybrid with Expanding Symbol Free Spins
• Progressive: No

Faust is one of the more thematically ambitious titles in the Greentube back catalogue, drawing on Goethe’s German philosophical drama for its symbol set. The reels feature Faust himself, his beloved Gretchen, scale symbols representing the protagonist’s twin pursuits of knowledge and material wealth, alongside Mephistopheles as the Devil figure and standard playing card royals on the lower paytable.

The mechanical signature is the Mephistopheles wild-scatter hybrid. Mephistopheles substitutes for all regular symbols to complete winning combinations and simultaneously functions as the scatter that triggers the free games bonus. The free games round runs on the Greentube expanding symbol mechanic familiar from Book of Ra Deluxe and Lord of the Ocean: at the start of the bonus, one symbol is selected to become the expanding symbol for the duration of the round, expanding to fill its entire reel when it lands.

A gamble feature is available after winning spins. Specific RTP, paylines, and max win figures are not published on the developer’s brand pages.

Garden of Riches

• Theme: Fairy tale
• Best Feature: Sticky Wild Free Games
• Progressive: No

Garden of Riches is a fairy-tale themed Greentube slot rendered in soft pastels, with a Fairy Princess as the central character alongside butterflies, garden cottages, magical flowers, and standard card royals on the lower paytable. The setting and presentation make this one of the more visually distinctive entries in the classic Greentube catalogue.

The free games bonus round triggers when the scatter symbol lands enough times on the reels. During the bonus, additional Fairy Princess wilds can land on any reel and stay locked in position for the remainder of the round, gradually filling the grid with sticky wilds and increasing the probability of significant wins on later spins. The accumulating sticky wild mechanic gives the round a structural arc that builds across the bonus rather than depending on a single high-multiplier hit.

A gamble feature is available after winning spins. Specific RTP, paylines, and max win figures are not published on the developer’s brand pages.

Sizzling Hot Deluxe

• Theme: Classic fruit machine
• Best Feature: Star Scatter Pays
• Progressive: No

Sizzling Hot Deluxe is one of Greentube’s Novomatic Blue Chip classics, sitting alongside Book of Ra Deluxe and Lucky Lady’s Charm Deluxe as the cornerstone titles of the developer’s online catalogue. Greentube’s own product copy describes it simply: classic slot fun, the burning fruits of Sizzling Hot Deluxe.

The 5-reel grid runs a classic European fruit machine paytable with cherries, lemons, oranges, plums, grapes, watermelons, the Lucky 7, and the Star scatter. There are no free spins, no wilds, and no bonus rounds. The Star scatter pays out anywhere on the reels regardless of payline position, and the maximum win comes from landing the highest-paying symbol across an active payline.

A gamble feature is available after winning spins. The Cash Connection version of Sizzling Hot uses a 5-reel, 5-win-line layout, suggesting the original Sizzling Hot Deluxe shares a comparable core structure. Specific RTP and max win figures are not published on the developer’s brand pages.

Lucky Lady’s Charm Deluxe

• Theme: European lucky charms
• Best Feature: Free Spins with Multiplier
• Progressive: No

Lucky Lady’s Charm Deluxe is one of the three Novomatic Blue Chip classics that Greentube features prominently in its corporate materials. Greentube describes the slot as the famous blonde beauty of Lucky Lady’s Charm Deluxe, a recurring fan favourite across the developer’s European footprint and a consistent fixture in regulated markets including the UK, Germany, Spain, Portugal, Switzerland, and Slovenia.

The Lucky Lady herself acts as the wild and headline character, alongside horseshoes, four-leaf clovers, ladybirds, and rabbit feet covering the European lucky charm theme. The Crystal Ball acts as the scatter, triggering the free games feature when enough land on the reels.

A gamble feature is available after winning spins. The Deluxe version is the most widely available iteration at Greentube-supplied online casinos. Specific RTP, paylines, free spin counts, and max win figures are not published on the developer’s brand pages.

Book of Ra Deluxe

• Theme: Ancient Egypt
• Best Feature: Special Expanding Symbol Free Games
• Progressive: No

Book of Ra Deluxe is described in Greentube’s own 2016 casino brochure as “the most popular slot of NOVOMATIC”, with the brochure also confirming the format: 10 paylines, 5-reel deluxe version, with treasures and wealth hidden in the vaults of ancient Egyptian temples. The slot is the cornerstone of the entire Book of Ra series, which has since expanded with sequels including Book of Ra Deluxe 6, Book of Ra Deluxe 10, Book of Ra Deluxe Win Ways, and the Cash Connection Book of Ra and Golden Book of Ra variants.

The mechanical signature is the Special Expanding Symbol free games feature. The Book itself acts as both wild and scatter. Landing enough Books triggers the free games round, and at the start of the feature one symbol is selected at random to become the expanding symbol for the duration of the bonus. Whenever that symbol lands on the reels, it expands vertically to fill its entire reel.

The Egyptian theme is handled with the seriousness the subject warrants, with hieroglyphic tiles, Pharaonic figures, and the explorer character among the standard paytable symbols. A gamble feature is available after winning spins. Specific RTP and max win figures are not published on the developer’s brand pages, but Book of Ra Deluxe remains the benchmark against which every subsequent Book-of slot has been measured.

Lord of the Ocean

• Theme: Greek mythology / Poseidon
• Best Feature: Special Expanding Symbol Free Games
• Progressive: No

Lord of the Ocean runs on the same core Greentube mechanic as Book of Ra Deluxe but swaps the Egyptian setting for a Greek mythology underwater theme. Greentube’s product copy is direct: Poseidon himself invites players to his realm in Lord of the Ocean and Lord of the Ocean Magic, on a quest for sunken riches and mythical artifacts, including special expanding symbols and Free Games.

Poseidon acts as the highest-paying symbol and as the special expanding symbol. The 10 Win Ways version of the slot, separately released by Greentube, confirms the original’s underlying configuration and feature set: 5 reels, 10 win lines, an expanding symbol Free Games feature, and a quest-for-treasure narrative. Mermaids, treasure chests, ancient statues, and standard playing card royals fill out the paytable.

A gamble feature is available after winning spins. The free games round is the primary route to the slot’s bigger payouts, particularly when Poseidon expands across multiple reels simultaneously. Specific RTP and max win figures are not published on the developer’s brand pages.

Santa’s Riches

• Theme: Christmas / North Pole
• Best Feature: Cascading Reels with Free Games
• Progressive: No

Santa’s Riches is one of Greentube’s Christmas-themed slots, set against a North Pole backdrop with snow-covered reels, Santa himself, and festive symbols including stockings, holly, and gold bells alongside lower-value card icons. The visual design leans into the seasonal imagery without departing from Greentube’s standard production style.

The slot uses a cascading reels mechanic, which is less common across the Novomatic catalogue than the standard reel-spin format. When a winning combination lands, the contributing symbols disappear and new symbols drop in from above, making consecutive wins from a single spin possible without any additional wager. The Wild substitutes for all other symbols to help complete winning combinations, and the free games bonus round triggers via a feature trail mechanic rather than a standard scatter.

A gamble feature is available after winning spins. Specific RTP, free spin counts, and max win figures are not published on the developer’s brand pages.

Cops ‘n’ Robbers

• Theme: Crime comedy
• Best Feature: Multiple Bonus Routes Including Free Games
• Progressive: No

Cops ‘n’ Robbers is part of Greentube’s lineup of crime-themed slots, sitting alongside Gangster Paradise on the catalogue’s law-and-order shelf. The crime-comedy presentation runs with policewomen, policemen, judges, and police cars filling the higher-paying symbol tier, with playing card royals on the lower paytable. The dog acts as the wild symbol, substituting for all regular symbols to complete winning combinations.

Multiple bonus routes run within the slot, including a free games feature triggered by the scatter symbol. Greentube’s own product copy positions this slot as one of the more feature-rich entries in the developer’s classic catalogue.

A gamble feature is available after winning spins. Specific RTP, multiplier values, free spin counts, and max win figures are not published on the developer’s brand pages.
