Novomatic Software Review – The Company Behind Book of Ra and Greentube

Novomatic put more slot machines on European floors than almost anyone else.

In this Novomatic review, we look at how the Novoline classics behind Book of Ra and Sizzling Hot hold up online: the most popular slots, jackpots, mobile play, and security, and the role of Greentube, the group’s digital arm.

Novomatic started in Austria in 1980 and grew into one of Europe’s largest gaming technology groups, running everything from machine manufacturing to its own casino chains.

Online, the group works through Greentube, the Vienna-based division that ports the Novoline floor catalog to desktop and mobile and licensed it into 45+ countries, with US launches in Pennsylvania and Delaware following in 2025.

The group also runs its own Admiral casino brands across Europe, both online and in venues.

Expert Verdict – Is Novomatic Worth Playing?

Yes, if you value simplicity and volatility over spectacle. We tested the Greentube versions on desktop and mobile, and the Novoline classics play exactly like their land-based originals: fast, stripped-back, and unforgiving in the best way.

Book of Ra remains one of the most influential slots ever made, and the Gamble feature adds a risk decision most modern studios have dropped. The catch is the math profile: eight of the ten titles in our table sit around 95% RTP, below the 96% industry norm.

Best Novomatic Games: Top Picks and Must-Try Titles

Slots dominate the catalog, and one franchise towers over the rest: Book of Ra and its many sequels. Still, the range of Novomatic casino games is wider than the Novoline stereotype: Greentube also produces RNG blackjack and roulette, plus the Diamond Mystery progressive jackpot series.

The sections below break the catalog down by category, including our picks for the best Novomatic games in each one, so you can head straight for what you play.

Expect consistency over novelty: the house style has barely changed in twenty years, and its fans consider that the whole point.

Novomatic Slots: Popular Titles, RTP, and Unique Features

Novomatic slots are the definition of land-based classics online. Most run five reels with five to ten paylines, minimal animation, and a high-volatility math model built around expanding-symbol free spins. Titles like Book of Ra Deluxe dominated European arcades years before their online versions arrived.

The trade-off is a familiar one: character over payout rate. Most of the catalog clusters around 95% RTP, so the appeal is the ride, not the long-run return.

If RTP is your first filter, many Playtech slots pay closer to 96%, though Columbus Deluxe (96.31%) is a house exception.

Reading the table is straightforward once you know what each column measures. RTP is the long-run percentage a game returns on everything wagered, volatility describes how that return arrives (steady trickle or rare bursts).

The bet range tells you whether your bankroll fits, and the max win is the theoretical ceiling on a single spin.

If you want to try any of these Novomatic online slots without risk, nearly every title has a free demo, and our guide on how to play slots is the place to start if you’re new.

RNG Table Games by Novomatic

Greentube produces a wider range of RNG table games than its slots-first reputation suggests, including several roulette variants, baccarat, and blackjack. The math follows the book: single-zero roulette returns the standard 97.30%, and blackjack pays above 99% with optimal decisions.

Don’t expect the variant depth of a table specialist. There are no game-show hybrids and few side bets; the target player wants the casino floor’s core tables and nothing else. In our sessions they ran without a hitch on desktop and phone, with layouts that favor function over flair.

If tables are your priority, pick a casino stocking several suppliers at once. Novomatic’s versions round out a slots session; they don’t carry one. In the US, Greentube’s launches so far lead with slots, so expect these tables mainly at European casinos.

The full list is longer, so we picked the four most interesting. Globe Roulette is the straight European table: single zero, French betting options, and a quick-spin control for fast sessions, with stakes starting at $0.10.

Royal Crown Roulette runs the same single-zero math behind a close-up 3D wheel and takes chips from as little as $0.01.

Lucky Lady’s Roulette puts the Lucky Lady’s Charm theme on the wheel and adds bonus numbers: after betting closes, the Lucky Lady picks up to four, with multipliers worth up to 210x a straight stake. Straight-up wins pay 30 for 1 rather than 35 to fund the feature.

The Baccarat table, meanwhile, keeps the classic player-banker-tie layout with nothing bolted on.

Live Casino Games by Novomatic

There are no Novomatic live dealer games. The group’s strength is machines and RNG content, and Greentube has stayed out of the studio-streaming business and leaves live tables to the dedicated suppliers.

That leaves an easy pairing: most casinos carrying Greentube content also stock live tables from specialists, and Playtech live studios in particular share lobby space with Novomatic slots across Europe.

Other Novomatic Casino Games: Jackpot Series & Beyond

The most interesting corner outside the classics is Diamond Mystery, Greentube’s four-level progressive jackpot series, which wraps familiar Novoline-style reels around locally pooled prizes.

Greentube also produces AWP-style titles for markets that grew up on arcade machines, along with occasional themed spin-offs of the big franchises. These stay deliberately simple: three or five reels, few features, quick rounds.

Exclusive and Branded Casino Games by Novomatic

Novomatic rarely licenses outside brands; its exclusives are its own franchises. Book of Ra is the house Monopoly: the Deluxe version is a fixture of European casinos, and the family has grown sequels from Book of Ra Magic to Deluxe 6.

Sizzling Hot and Lucky Lady’s Charm carry the same weight in the fruit and charm niches.

That self-owned stable is a strength. Nobody can pull the license, and twenty years of continuity is why a Novoline player can sit at any version and know the rules by heart.

Standout Features, Technology & Innovation

Novomatic’s signatures are older than most studios, and that’s precisely their appeal: mechanics proven on arcade floors, ported without dilution. Four of them define the house style.

Original? The expanding-symbol free spin genuinely was, and the industry spent a decade imitating it. The Gamble feature survives at few other studios, while the jackpot layer is Greentube catching up to a market standard the industry set years ago.

Mobile Experience with Novomatic Games

Greentube rebuilt the catalog in HTML5, so phones and tablets get the same games with no app required. Our test sessions on iOS and Android matched desktop spin for spin, and the sparse Novoline interfaces translate to small screens better than most modern, button-heavy slots.

Simplicity is the advantage here: five paylines and two buttons need little adaptation.

Progressive & Fixed Jackpots

Novomatic built its name on fixed prizes, not network progressives. The classics carry famous ceilings: a free-spins screen full of explorer symbols in Book of Ra Deluxe pays 5,000x the stake, and Lucky Lady’s Charm Deluxe tops out at 4,633x the total bet.

Progressive play arrived with Greentube. The Diamond Mystery series adds a four-level jackpot that can trigger on any spin and pays up to 5,000x the stake depending on the title, while the newer Diamond Link games (Mighty Sevens among them) run the familiar Mini, Minor, Major, and Grand ladder.

Prizes are pooled locally rather than globally, so they hit more often and lower than the giant international networks.

Fixed ceilings mean you always know the maximum before you spin. It suits the house philosophy: the thrill is volatility inside the base game, not a life-changing side prize.

Security, Licensing & Fair Play

Greentube’s licenses come from regulators with the toughest technical standards, including the UK Gambling Commission and the Malta Gaming Authority, with US state approvals following the 2025 launches in Pennsylvania and Delaware.

The compliance record in this Novomatic review was the simplest part to check: the group has operated under European regulation since 1980.

Independent test labs including GLI and SIQ verify the random number generators behind every regulated release. Each game publishes its certified RTP in the paytable, so the theoretical return is checkable before you stake anything.

Regular payout audits are a license condition, and the operators carrying these games publish their aggregate results.

Responsible Gaming Tools & Player Protection

The safety net around a Novomatic game comes from the regulator of the market you play in, layered with the casino’s own controls. Expect session reminders and a visible clock, plus deposit or stake caps at account level wherever the license requires them.

Decide your limits before the first spin; changing them mid-session is exactly the decision the tools exist to prevent.
