Top slots

GamesHighlights
Book of RaA theme of an explorer searching for Egyptian ruins. A single symbol expands across the whole reel during free spins, and it became the prototype for countless “Book of” slots that followed
Sizzling HotA simple classic 5-reel slot with fruit symbols. It has only basic wins, with no bonus
Lucky Lady’s CharmA classic slot with a luck theme
Dolphin’s PearlA classic slot with an ocean theme

Novomatic slots are known for the “classic Novo” style long loved in German-speaking gaming halls. They favor simple structures over flashy features, and often use the gamble feature (staking your win to guess a card color).

Greentube

Greentube is an online gaming subsidiary that Novomatic acquired in 2010. It brings Novomatic’s popular offline slots online and also creates new online slots. In 2021, the UK Gambling Commission imposed a fine of about 685,000 pounds on Greentube for inadequate anti-money laundering measures.

Controversies

Given its size, it has also drawn controversy in several countries. In 2014 it settled with Italian tax authorities for 47.5 million euros, and allegations related to lobbying and corruption have been raised in Poland and Romania. In Austria, its name also came up during the investigation of the 2019 political scandal (the “Ibiza affair”). These cases show that the relationship between large gambling companies and politics and regulators is always under scrutiny.

The prototype of the “Book of” genre

The core feature of Book of Ra is that when free spins begin, one randomly chosen symbol becomes a “special expanding symbol.” If enough of this symbol appears during free spins, it spreads across the entire reel regardless of paylines and creates a big win. This simple yet tense structure became hugely popular, and other providers produced similar games such as “Book of Dead” and “Book of Cats.” That is how “Book of” came to be a genre of its own.

The German market and Novomatic

Novomatic holds a large share of the German gaming hall (slot arcade) market. In 2021, Germany legalized online slots under a new interstate gambling treaty and introduced strict rules such as a 1 euro bet limit and a 5-second spin interval (Germany’s GGL). So the Novomatic classic slots familiar to German players are offered online in versions adapted to these rules.

What to know when playing classic slots

  • Classic Novo slots may have an RTP around 95%, lower than modern online slots. Check the game info screen (RTP).
  • In games without a bonus, like Sizzling Hot, wins come only from the base game, so the flow is monotonous, but the structure is easy to understand.
  • The gamble feature does not raise the expected value. It only increases volatility.

Headquarters

Novomatic is headquartered in Gumpoldskirchen, Austria.
