Greentube has expanded its online casino portfolio with Flaming Devil, a new slot built around a classic devil-themed setting and a combination of familiar reel mechanics and interconnected bonus features. The release offers 243 ways to win and places a strong emphasis on a Devil Collect mechanic that can operate throughout the base game.

As the NOVOMATIC Digital Gaming and Entertainment division, Greentube continues to develop casino content that combines established slot concepts with feature systems intended to create greater variety during gameplay. Flaming Devil follows that approach by making its central collection feature available from the regular game rather than restricting it to a dedicated bonus sequence.

The title combines an underworld-inspired theme with coin prizes, Free Games and a multiplier mechanic. Together, these elements create a structure in which the base game and bonus round are closely connected.

A familiar theme supported by layered mechanics

Flaming Devil places a mischievous devil at the centre of its presentation. The theme draws on a familiar concept within the online slot sector while the gameplay introduces several linked features intended to give the title additional depth.

The game offers 243 ways to win, providing a straightforward foundation for the reel action. Alongside standard wins, Devil symbols can collect coin prizes displayed on the reels.

This mechanic gives the base game an additional point of interest because the feature is not limited to Free Games. A Devil symbol landing during regular play can collect the relevant coin prizes on screen and add them to the spin outcome.

The structure allows Greentube to retain an accessible gameplay format while introducing a feature that can influence individual spins. Rather than making the bonus round the sole source of additional mechanics, Flaming Devil gives players access to its signature feature during the main game as well.

How the Devil Collect feature works

The Devil Collect feature is one of the defining mechanics in Flaming Devil. When a Devil symbol lands on the reels, it collects the coin prizes currently displayed and awards their corresponding values.

The feature is significant because it operates on every spin rather than being reserved for a particular bonus stage. This creates a direct connection between the game's regular gameplay and its wider collection-based design.

The Devil symbol also becomes increasingly important once players enter the Free Games feature. Collected Devil symbols can contribute to the progression required to activate the Free Games Wheel, giving the central symbol a continuing role beyond the base game.

The mechanic is relatively simple to understand, which supports the game's accessible positioning. At the same time, its interaction with the bonus features provides an additional layer for players who reach the Free Games round.

Free Games introduce further progression

Landing three or more Bonus symbols triggers the Free Games feature. During this round, collecting four Devil symbols awards access to the Free Games Wheel.

The wheel can provide additional Free Games or increase the Free Games Multiplier. The multiplier then applies to collected Devil symbol wins for the remainder of the Free Games round.

One of the more notable aspects of the feature is the possibility of triggering the wheel multiple times during a single round. This gives the bonus sequence a more progressive structure because another trigger can extend the round while also potentially increasing the multiplier.

For Flaming Devil, this creates a clear relationship between the collection mechanic and the bonus feature. The Devil symbol is important during regular play and continues to influence the outcome after Free Games are activated.

The repeated wheel mechanic also gives the bonus round a variable structure. Rather than following one fixed sequence, the feature can develop differently depending on the symbols and triggers that occur during the round.

Richard Ganster outlines Greentube's approach

Richard Ganster, director of games strategy and games portfolio management at Greentube, said the company aimed to combine a familiar concept with a distinctive feature structure.

“With Flaming Devil we wanted to give players something instantly familiar but with a real spark of personality. The Devil Collect feature is active on every spin, not just during the bonus round, so there’s always something to keep attention fixed.

“The Free Games Wheel is a key highlight. It can be awarded multiple times in the same round and the Free Games Multiplier can stack significantly, giving the title a strong ceiling on win potential while keeping the base action pace accessible. Flaming Devil is a strong example of the direction we’re taking with our portfolio. Familiar, accessible themes paired with layered features that give players more reasons to stay engaged.”

His comments highlight the intended balance between recognisable gameplay and additional feature depth. Flaming Devil uses an established slot theme while connecting its main mechanics around the Devil symbol.

Part of Greentube's wider games portfolio

The release comes as Greentube continues to develop its portfolio of online casino content for regulated markets. The supplier offers a broad range of gaming products that includes slot games, table games, video poker and video bingo.

Greentube's catalogue includes both established titles and newer releases. The company has continued to use familiar themes alongside mechanics designed to create different gameplay experiences across its portfolio.

Flaming Devil fits within this wider approach by using a recognisable theme as its entry point while adding several interconnected features. The combination of 243 ways to win, Devil Collect, Free Games and the Free Games Wheel gives the title a distinct mechanical identity.

The game is also listed among Greentube's 2026 releases and was highlighted by the company ahead of its August launch. Its inclusion in the supplier's wider showcase demonstrates the importance placed on new feature-led content alongside established game families.

Regulatory considerations remain important

The availability of Flaming Devil will depend on the jurisdictions and operators where the game is approved and supplied. As with other online casino titles, access can vary according to local regulatory requirements, licensing conditions and operator decisions.

Greentube identifies itself as a regulated gaming supplier and operates across multiple regulated markets. The UK Gambling Commission's public register lists Greentube GmbH under account number 41020 with an active remote gambling software licence.

Greentube Malta Limited is also listed by the Malta Gaming Authority under licence MGA/CRP/120/2006. These regulatory arrangements provide important context for the distribution of online casino content and the requirements applicable to operators and suppliers.

Players should use licensed gambling services where online casino play is permitted and should consider the responsible gaming rules that apply in their jurisdiction. Features such as multipliers and collection mechanics represent elements of game design and should not be understood as guarantees of winnings.

Conclusion

Flaming Devil gives Greentube another feature-led addition to its growing online casino portfolio. The game combines a familiar devil-themed concept with 243 ways to win and a collection mechanic that remains active beyond the bonus round.

Its Devil Collect feature provides the foundation for the title's additional gameplay while the Free Games feature introduces a more substantial bonus sequence. The Free Games Wheel adds another level by offering additional Free Games and the possibility of increasing the multiplier applied to collected Devil symbol wins.

The ability to trigger the wheel more than once during a Free Games round gives the bonus feature a progressive quality and helps connect the game's different mechanics into one coherent system.

From a broader portfolio perspective, Flaming Devil reflects Greentube's stated approach of pairing familiar themes with layered gameplay features. Rather than relying solely on its visual concept, the title gives its central Devil symbol a functional role throughout the experience.

With its combination of accessible mechanics and interconnected features, Flaming Devil represents another step in Greentube's ongoing development of online casino content for regulated markets. Its final availability and configuration will depend on the relevant jurisdictions and licensed operators while its core design remains focused on collection mechanics, Free Games and feature progression.
