Gorilla was developed by Greentube, the online and mobile arm of Austria's NOVOMATIC Group. The studio traces back to 1998 and was fully folded into NOVOMATIC by 2011.
- Headquartered in Vienna, Austria, with subsidiaries across Europe and North America.
- Holds licences including the Malta Gaming Authority and the UK Gambling Commission.
- Gorilla sits among dozens of classic video slots in Greentube's library, not a flagship release.
Inside Greentube's Studio Background
Greentube began under a different name in the late 1990s before restructuring into Greentube GmbH and being absorbed into the NOVOMATIC Group through a majority stake acquired in 2010 and completed integration by 2011. The company is run by CEO Thomas Graf alongside a management team covering operations, finance, technology and compliance, with staff counts commonly cited in the 500-to-1,000 range across corporate directories.
Within NOVOMATIC, Greentube functions as the digital gaming and entertainment division, converting the parent group's land-based cabinet titles into online and mobile formats while also building server-based and social casino products. Its licence portfolio spans the Malta Gaming Authority, the UK Gambling Commission and several U.S. state regulators, backed by testing from independent labs and certifications such as G4 and ISO 27001 at the corporate level.
The studio's reputation rests heavily on flagship conversions of NOVOMATIC's arcade classics, including Book of Ra deluxe, Sizzling Hot deluxe and Lucky Lady's Charm deluxe, alongside recurring jackpot families like Diamond Link and Diamond Cash. These titles anchor the catalogue and account for most of the brand recognition attached to Greentube.
Gorilla belongs to a wider tier of the catalogue: a conventional five-reel, 50-line video slot with a jungle theme, scatter-triggered free spins and a gamble feature, built with the same land-based-inspired mechanics the studio applies across many of its releases. Nothing in available operator or distributor material suggests it was treated as a marquee launch or a mechanical departure from Greentube's usual formula.
Distribution follows the standard supplier model: Greentube integrates its HTML5 content directly with licensed operators and through platform partnerships, and slot-tracking services report Gorilla listed across dozens of casinos in numerous countries. This places the game inside mainstream, multi-provider casino lobbies rather than on niche or single-brand platforms.
Player-facing feedback specific to Gorilla is thin. Catalogue and database listings for the game frequently show no user rating or submitted comments, so most of what can be said about its reception rests on the studio's broader track record rather than on documented player sentiment for this particular title.
Gorilla RTP Range
95.09%
Greentube's own catalogue lists Gorilla at 92.06%, while several operator-configured builds elsewhere report 95.09% or 96.14%; the exact figure in play depends on which casino version is loaded.

- Gamble feature

- Scatter symbol

Frequently Asked Questions
Is Greentube the same company as NOVOMATIC?
No. Greentube is a separate legal entity that operates as NOVOMATIC's digital gaming and entertainment division, handling online, mobile and server-based content while NOVOMATIC's broader group covers land-based manufacturing and operations.
Does Greentube hold licences relevant to operators serving Canadian players?
Greentube's corporate licensing includes the Malta Gaming Authority and the UK Gambling Commission plus several U.S. state approvals, but no Canadian provincial regulator listing naming Gorilla with certified math specifics was found in available records.
Why does Gorilla show different RTP figures across casino sites?
Greentube's catalogue specifies 92.06%, but individual operators can configure their own build of the game, which is why third-party listings quote 95.09% or 96.14% instead.
Is Gorilla considered one of Greentube's flagship titles?
No. Operator and distributor material treats it as a standard entry in a large catalogue, alongside better-known franchises such as Book of Ra deluxe and Sizzling Hot deluxe.
Does Greentube publish player ratings for older titles like Gorilla?
Public slot databases generally show no aggregated user rating or comment volume for Gorilla, so player sentiment data for this specific title is largely absent.
Assessing Greentube as a Studio
Right for Players who value dealing with an established, multi-jurisdiction licensed supplier and are comfortable with a traditional line-slot format.
Wrong fit for Players looking for a studio's most modern, feature-dense release or for a single, universally confirmed RTP figure before playing.
Greentube's corporate footprint, licensing record and decades-long integration into NOVOMATIC support confidence in it as a supplier, even where per-game documentation for an older title like Gorilla is limited. The game itself is a conventional, competently built five-reel slot rather than a technical showcase.
