Novomatic Slots – Greentube Games Review
From Cabinets to Online Platforms
Novomatic first made its mark with slot cabinets, electronic roulette, and sports betting terminals. Many of these titles became fixtures in European arcades and casinos. Greentube’s role has been to adapt these popular land-based games into online versions, making titles like Book of Ra Deluxe, Sizzling Hot Deluxe, and Lord of the Ocean available across digital platforms.
This transition has ensured that Novomatic’s games remain relevant as player behaviour has shifted from physical venues to UK online casinos.
Game Portfolio
Greentube’s portfolio now exceeds 400 games. While slots make up the majority of the catalogue, the company also develops table games, video poker, video bingo, and social casino platforms. Alongside faithful adaptations of Novomatic classics, new titles are created under the Greentube brand to meet the demands of online audiences.
Features and Systems
In addition to standalone games, Greentube develops a range of systems and platforms:
- Diamond Mystery™ – a series of slots enhanced with four-level progressive jackpots.
- Plurius™ – a server-based gaming solution enabling operators to run linked content across land-based, online, and mobile channels.
- Greentube Mynt – a development and distribution tech stack designed for modern iGaming.
- Greentube Pro – a white-label platform for social casinos and branded loyalty apps.
Global Licensing and Reach
Greentube is licensed in multiple key jurisdictions, including by the UK Gambling Commission and the Malta Gaming Authority, allowing distribution across regulated European markets and, more recently, into North America. In 2025, the company launched in both Delaware and Pennsylvania, marking further expansion of Novomatic’s online presence.
Notable Titles
Some of the most recognisable Novomatic and Greentube titles include:
- Book of Ra Deluxe – one of the industry’s most famous “Book of” style slots.
- Dolphin’s Pearl Deluxe – a long-running ocean-themed title adapted for online play.
- Lord of the Ocean – a mythological slot that remains a mainstay in many online casinos.
- Sizzling Hot Deluxe – a fruit slot that represents Novomatic’s classic land-based legacy.
Our Two Favourite Novomatic and Greentube Slots
Book of Ra
Book of Ra is Novomatic’s most famous online slot. It’s also widely found in land-based casinos and has inspired numerous clones and reboots. The original game features five reels and nine paylines. Set in ancient Egypt, the slot follows a lead character on a quest through different cities to find a mysterious book. Landing symbols such as scarabs, golden statues, or other relics from the era can award free spins or cash prizes. One of the reasons for the game’s enduring popularity is its frequent payouts, which have helped it remain one of the most played and recognisable slots worldwide.
Cops N Robbers
Cops N Robbers is a video slot featuring a robber named Bert and his dog Bonzo. Alongside them is a police officer, a Las Vegas backdrop, and the chance to win up to 10,000× your bet. If you manage to land five winning symbols – especially Bert with the maximum multiplier – you can unlock the game’s biggest rewards. The slot also includes multiple bonus rounds, free spins, and a variety of lower-paying symbols.
