NOVOMATIC Slots and Casino Software Guide

NOVOMATIC: An Introduction

NOVOMATIC is one of the biggest names in gambling. The Austrian group makes slot machines, casino equipment and game software. It also runs casinos and gaming halls in several countries.

Most online players know NOVOMATIC through its famous slots. Book of Ra, Lucky Lady’s Charm and Sizzling Hot are among the best-known games in Europe. Online, these games are supplied through Greentube, the group’s digital gaming division.

This guide explains who NOVOMATIC is and how Greentube fits in. It also covers the games to look out for and what to check before you play.

NOVOMATIC at a Glance

Company History

NOVOMATIC was founded in Austria in 1980. It celebrated its 45th anniversary in 2025. Over those years, it has grown from a small machine maker into a global gaming group.

The group’s head office is in Gumpoldskirchen, near Vienna. From there, it runs a wide network of companies that build machines, write game software and operate gaming venues.

The group has grown through deals too. In 2016, it agreed to buy a majority stake in the Australian machine maker Ainsworth Game Technology. More recently, in 2025, it bought the French Vikings Casinos group. It also gained a gaming vendor licence in the United Arab Emirates. NOVOMATIC also ranks among Austria’s most valuable brands, second only to Red Bull in a 2026 brand value study.

NOVOMATIC and Greentube

NOVOMATIC’s online games come from Greentube, which calls itself the NOVOMATIC Digital Gaming and Entertainment division. Greentube adapts the group’s classic machine games for online play and also builds new digital slots.

Greentube GmbH holds a remote gambling software licence from the UK Gambling Commission under account number 41020. Greentube also publishes licensing information from the Malta Gaming Authority.

Keep in mind that a supplier licence covers the company that makes the games. It does not mean every casino showing a NOVOMATIC slot is licensed where you live. Our guide to online gambling licences explains the difference.

Popular NOVOMATIC Slots

NOVOMATIC is best known for simple, classic slots. Many of them use just a few paylines and a straightforward free spins round. That style has made them favourites for years, especially across much of Europe.

Classic Titles and Other Reviews

Many older NOVOMATIC releases are still familiar to slot players. We have reviewed Royal Dynasty, Pharaoh’s Ring, Magic Jester and Lord of the Ocean. Bear in mind that not every older title is still offered online.

You can also read our reviews of Hold Your Horses, Hoffmania and Always Hot Cubes. If you are new to online slots in general, our casino games guide is a good place to start.

How NOVOMATIC Slots Play

Classic NOVOMATIC slots follow a familiar pattern. Once you have played one, you will feel at home with most of the others.

• Few paylines. Many classics use 5, 9 or 10 paylines rather than hundreds of ways to win.
• Free games. Scatter symbols usually trigger a round of free games, often with a special feature.
• Expanding symbols. In the book-style games, a random symbol expands to fill whole reels during free games.
• Gamble feature. After a win, you can often guess the colour of a playing card to double your prize or lose it.

This simple style is a big part of the appeal. The rules are easy to learn, and the games move quickly. On the other hand, players who want big multipliers and complex bonuses may prefer the newer Greentube titles.

Land-Based and Online Games Compared

NOVOMATIC builds games for two very different worlds. It is worth knowing how they differ.

Greentube’s Newer Online Games

Greentube does more than convert old machine games. It also releases new titles built for online play. Its own portfolio highlights games such as Highway to Bell Stack & Collect and Flaming Devil. Piggy Prizes and the Cash Connection series also feature.

These newer games often add features that the classic titles lack. For example, you will find hold and win style bonuses, collect features and linked jackpots. As a result, the range now suits both fans of simple classics and players who want more action.

Which games you can play depends on the casino and on local rules. Greentube games are only available at casinos that have a deal with the studio and approval in your market.

Jackpots, Mobile Play and RTP

NOVOMATIC slots range from plain reel games to titles with bonus rounds, mystery prizes and jackpots. Jackpot rules and prize sizes vary from game to game and casino to casino.

Most Greentube games work in a mobile browser on phones and tablets. There is usually no app to download. Even so, the exact range on mobile depends on the casino you use.

RTP also varies from title to title. In addition, casinos can sometimes choose between versions of the same game. Always open the game rules and check the RTP before you play.

Where to Play NOVOMATIC Slots

NOVOMATIC games are mostly found at European online casinos. Availability is more limited in some other regions, so always check the casino’s game lobby first.

Before you sign up, make sure the casino holds a valid licence for your country. Also check the payment options and any bonus terms. Our casino safety guide covers the main checks.

Regulatory Record

NOVOMATIC’s UK online casino arm has faced regulatory action. Greentube Alderney ran the Admiral Casino UK site. It agreed a £685,000 settlement with the UK Gambling Commission over anti-money laundering and safer gambling failings.

In January 2025, the same company agreed a further £1 million settlement for similar failings. These cases relate to the casino sites Greentube Alderney operated, not to the games themselves. Even so, they are worth knowing about when you judge the group as a whole.
