Quick take: Best for players who enjoy classic fruit machines and book-style adventures — and a growing catalog of modern Hold & Win titles.
Novomatic was founded in 1980 by Johann Graf in Gumpoldskirchen, Austria. Over four decades it grew from a single gaming cabinet manufacturer into one of Europe's largest gambling groups, with over 26,000 employees operating across more than 50 countries.
Online games are handled by Greentube, Novomatic's digital division, acquired in 2010 and based in Vienna. Greentube's catalog now covers over 400 online titles and holds licenses from both the UK Gambling Commission and the Malta Gaming Authority.
Novomatic built its reputation on clear, land-based style play. Titles like Book of Ra Deluxe and Sizzling Hot Deluxe set a template that still defines the brand: modest reel counts, clean paytables, and bonus rounds driven by expanding symbols and retriggerable free spins. That simplicity is the draw — nothing hidden, nothing overcomplicated.
Recent releases extend the same framework into modern formats. The Hold & Win mechanic — coin symbols lock in place across three respins — now runs through a dedicated series. Progressive jackpot tiers appear in select games via the Diamond Mystery™ system. Buy Bonus is being rolled out across the portfolio for players who want to skip straight to the feature.
Expanding symbols. A symbol is chosen at random before free spins begin. Every time it lands, it expands to fill the full reel. Free spins retrigger in most titles, so the bonus can run longer than the starting count suggests. This mechanic drives nearly every Novomatic classic and many newer releases.
Hold & Win. Coin symbols trigger a respin round. Each new coin that lands resets the counter to three. The round ends when the counter hits zero or all positions fill — at that point jackpot values are paid out. Magma Strike Blazing Jackpots and Twister Fortunes Hold & Win both use this format.
Stacked wilds. A wild symbol covers an entire reel, substituting for all paying symbols on that spin. Xpand variants extend this further, pushing wilds across additional reel positions mid-spin as seen in Phoenix Hotfire Xpand.
Book of Ra Deluxe is the most-played Novomatic slot worldwide. A single symbol is picked at random before free spins — that symbol then expands on every reel it touches. It is a mechanic many other studios have since copied. Sizzling Hot Deluxe strips things back to a five-reel fruit machine with no bonus round at all. Lord of the Ocean and Dolphins Pearl Deluxe follow the expanding-symbol blueprint in mythology and ocean settings. Lucky Lady's Charm Deluxe adds a multiplier wild to the same free spins structure.
These games predate the online era. Greentube ported them faithfully for browser and mobile play, keeping the original paytables intact where possible.
Greentube holds a UK Gambling Commission license under account number 45352 alongside a Malta Gaming Authority license. Content is available at regulated online casinos across 50+ markets. In 2025, Novomatic launched in Delaware and Pennsylvania, expanding its North American footprint.
