🗓️ Game studio spotlight published on May 21, 2025
Spinomenal is a game provider founded in 2014, based in Israel, with a large and continuously expanding slot portfolio. The studio is known for releasing a high number of titles across different themes, often built on similar core structures.
Instead of focusing on a small number of flagship games, Spinomenal follows a model where multiple variations of familiar mechanics are released under different themes. This approach makes their games recognizable, especially for players who prefer consistent gameplay formats.
Spinomenal is a game studio based in Israel, operating in multiple regulated markets under licenses such as the Malta Gaming Authority (MGA), ONJN (Romania), and Spelinspektionen (Sweden).
The company has developed a large portfolio of slot games, with hundreds of titles released across different themes. Many of these games are grouped into recurring series, where similar mechanics are reused with different visual styles.
Their themes range from mythology and ancient civilizations to horror and western settings, but the underlying structure of the games often remains consistent.
Spinomenal’s portfolio includes over 300 slots!
Here are some of the most played and recognized games from their collection:

Book of Baba Yaga – Winter Spell is a classic book-style slot, built on a 5 reel layout with 5 paylines. The gameplay follows a simple structure, where wins are formed from left to right using matching symbols.
The main feature is triggered by landing scatter symbols, which activate free spins. At the start of the bonus, one symbol is selected as the expanding symbol, allowing it to cover entire reels during the feature.
The game also includes a buy feature, giving direct access to the bonus round without playing through the base game.
Compared to other Spinomenal titles, this version keeps the mechanics minimal, with fewer paylines and a more straightforward flow focused on the bonus feature.
This title is part of a series that includes multiple variations, with a total of 6 versions built around the same core concept.
Theme: Slavic mythology, winter
Volatility: Not officially specified
RTP: Up to 96.18% depending on the version
Max Win: Up to 10,000x

Story of Zeus is built on a 5×4 layout with 20 paylines, where wins are formed from left to right across active lines.
The gameplay includes a free spins feature, which can award up to 50 spins depending on how the bonus is triggered. During this phase, additional elements such as extra wilds can appear to support winning combinations.
One of the key mechanics is the expanding wild with respin, where a wild symbol can expand across the reel and trigger an additional spin. This creates short sequences of repeated chances within a single feature.
Compared to other Spinomenal titles, the structure remains simple, but the use of expanding wilds and respins adds some variation to the standard format.
Theme: Greek mythology
Volatility: Medium-High
RTP: Up to 95.78%
Max Win: Not officially specified

Book of Rampage is a classic book slot, built on a 5 reel layout with 10 paylines. The gameplay follows a familiar structure, where matching symbols form wins from left to right across active lines.
The main feature is triggered by landing scatter symbols, which activate free spins. At the start of the bonus, one symbol is randomly selected as the expanding symbol, and it can cover entire reels when it appears during the feature.
In addition to the standard mechanics, the game also includes a buy feature, allowing direct access to the bonus round.
Compared to other Spinomenal titles, the structure here is simple and follows the same format seen across many of their “book” releases, with only minor variations between versions.
This title is part of a series that includes Book of Rampage 2 and Book of Rampage Moonlight Tale, continuing the same core gameplay with different visual themes.
Theme: Adventure, book-style
Volatility: High
RTP: Up to 96.14%
Max Win: Up to 5,000x

Demi Gods II is part of a larger Spinomenal series built on a 5 reel layout with 50 paylines, where the gameplay is focused on feature progression rather than a single bonus round.
The main system is based on a Free Spins Journey, where each triggered bonus advances the player through different stages. Each stage introduces a new feature or modifier, which can change how the spins behave.
The game includes multiple mechanics such as expanding wilds, stacked symbols, win multipliers, and additional wild variations that can appear during gameplay. These elements are combined through the progression system instead of being triggered all at once.
There are also variations in how the reels behave, including respin sequences and shifting wild mechanics, depending on the stage reached during the bonus.
Like many Spinomenal titles, this is not a standalone concept. The Demi Gods series includes 21 versions, all built around a similar structure with different themes and adjustments.
In addition, Spinomenal has released multiple “book-style” versions within this series, using the same expanding symbol mechanic across different titles.
Theme: Greek mythology
Volatility: Medium
RTP: Around 95%
Max Win: Not officially specified

Wolf Fang is one of the most recognizable slot series in the Spinomenal portfolio, built on a standard 5 reel setup with 30 paylines. The gameplay follows a familiar structure, with wins formed from left to right across active lines.
The game includes a free spins feature, where players can select between different bonus options through a Free Spins Pick system. This choice affects how the feature plays out, depending on the selected option.
Another available option is the Buy Feature, which allows direct access to the bonus round without playing through the base game.
A common element in the base game is the use of stacked symbols, which increase the chance of forming full line combinations.
What makes this title stand out is the number of variations built around the same concept. The Wolf Fang series includes over 20 versions, each using similar mechanics with different themes and adjustments.
This approach reflects how Spinomenal structures its portfolio, focusing on repeating a core system across multiple releases.
Theme: Wolves, nature
Volatility: Not officially specified
RTP: Up to 95.8% depending on the version
Max Win: Up to 1,000x
Spinomenal follows a model based on frequent releases and consistent game structure. The studio regularly introduces new titles, often built around reused core mechanics with different themes and visual variations.
A noticeable pattern across their portfolio is the use of similar gameplay systems. Many games share the same base structure, which creates a familiar experience for players who prefer predictable formats.
In terms of distribution, Spinomenal slots are available through multiple aggregator platforms, which allows their games to appear across a wide range of online casinos. This approach makes their content widely accessible without relying on a single platform.
The games are designed to run across both desktop and mobile devices, with layouts that adapt to different screen sizes while keeping the same gameplay structure.

Spinomenal is one of the providers with one of the largest game libraries. Almost every well-known title has multiple versions. For example, Wolf Fang has 27 versions (yes, I counted), and the same applies to other popular series.
Their main approach is built around the book style gameplay, where the same core mechanic is reused across different themes. In most cases, it comes down to reskinned versions with animals or mythology, while the structure of the game stays very similar.
In terms of volatility, I would describe it as medium to high. The bonus rounds in these book-style slots don’t often lead to very large wins, but they tend to return something more consistently, usually in the range of 200x to 300x. It’s not the type of gameplay where you expect a huge hit, but it can still pay out in a steady way.
The max win is generally hard to reach, and most sessions won’t come close to it. However, the visual presentation is modern and engaging, which makes the experience more enjoyable even without big payouts.
Overall, if you enjoy book book book style slots, Spinomenal is a good fit. I personally play them from time to time without expecting a big win, but the sessions are usually entertaining.
Spinomenal follows a very consistent approach, built around simple mechanics and repeated gameplay structures across different themes.
Most of their slots feel familiar from the first spin, since many titles reuse the same systems with visual changes. For some players, this creates a predictable experience, while others may find it repetitive over time.
If you’re a fan of Pragmatic Play, Play’n GO, or Nolimit City, you might find Spinomenal’s approach either refreshing or repetitive — but no one can deny their consistency and market presence.
Overall, their value comes from consistency and volume, rather than innovation in gameplay systems.
