Spinomenal Slots & Where to Play in the UK

By Jack Henshaw, Head Writer · Published 5 July 2026 · Last updated 9 July 2026

Spinomenal is the Israeli studio that has quietly become one of the industry’s highest-output suppliers: founded in Tel Aviv in 2014 by Lior Shvartz and Omer Henya, both veterans of social gaming before moving into real-money slots, it now ships 1–3 new titles a month and has passed 300 games without a single acquisition or ownership change along the way. Its catalogue leans heavily on Book-genre and animal-themed titles — the Wolf Fang and Story of… series in particular — distributed to over 850 casinos worldwide. Our verdict: 6/10. This review sifts the Spinomenal slots catalogue down to what deserves your time: the best Spinomenal slots ranked, what actually sets the studio apart, and the full licence file.

Where to Play Spinomenal Slots

Spinomenal at a glance

The essentials — a decade-old Israeli studio built on volume and consistency rather than one headline franchise.

The best Spinomenal slots: 10 games that actually matter

From the studio’s flagship savannah theme to its recurring Wolf Fang and Story of… series — ten games that represent Spinomenal’s high-output, theme-first approach. RTPs quoted are typical published defaults. The full ranked catalogue is near the end of the page.

1. Majestic King

Spinomenal’s clearest flagship: a savannah-lion theme on a 5-reel, 25-payline grid, later extended into an Expanded Edition running more paylines and reworked art. Consistently named among the studio’s best-regarded releases, and the closest thing Spinomenal has to a signature franchise. Spinomenal’s own game information sheet publishes four selectable RTP tiers — 88.69%, 92.16%, 94.04% and 96.31% — but doesn’t list a maximum win figure; third-party trackers cite wildly inconsistent numbers for it, so we’re not repeating an unverified one here — check the in-game paytable for the build you’re actually playing.

2. Book of Elves

A fantasy-forest take on the expanding-symbol Book format — one of several “Book of” titles in the catalogue, competing in the industry’s single most crowded genre. Solid execution rather than reinvention, but well-liked by returning players. Tom Horn Gaming returns to the same well even more often, with Book of Darius, Book of Cleo and Book of Vampires all running the identical template.

3. Story of Egypt: Egyptian Darkness

Part of the studio’s recurring “Story of…” naming convention, this entry takes a darker, more atmospheric turn on Egyptian theming than the genre’s usual sun-and-gold palette — a small but genuine point of differentiation.

4. Werewolf: The Hunt

A gothic horror theme distinct from the studio’s Wolf Fang series, leaning into genuinely tense atmosphere over the more straightforwardly commercial animal-print aesthetic found elsewhere in the catalogue.

5. Story of Medusa II

A Greek-mythology sequel extending an earlier house hit — part of the same “Story of…” family as Egyptian Darkness and Loki: Master of Illusions, showing the studio treating select themes as ongoing series rather than one-off releases.

6. Wolf Fang: Snowfall

One entry in Spinomenal’s most reused theme family, the Wolf Fang series, running 30 paylines and a Free Spins feature across an Arctic winter setting. The wolf-and-wildlife aesthetic reappears across at least four separate Wolf Fang titles.

7. Wolf Fang: The Polar Lights

A second Wolf Fang entry sharing the same Arctic wildlife cast as Snowfall but reskinned around the aurora borealis — the clearest example in the catalogue of one theme stretched across multiple releases with only cosmetic variation.

8. Story of Loki: Master of Illusions

A Norse-mythology entry in the “Story of…” series, leaning into Loki’s trickster reputation with an illusion-themed bonus structure — one of the more thematically creative entries in a catalogue that otherwise favours familiar genres.

9. Super Wild Fruits

A classic fruit-machine theme from the studio’s 2025 slate, running straightforward featureless-reel mechanics in the tradition Greentube established decades earlier — competent, if unremarkable next to the genre’s originators.

10. Reign of Seth

Another Egyptian-mythology entry, this one centred on the god Seth rather than the more commonly used pharaoh-and-pyramid imagery — rounding out the top ten with proof of just how many separate Egyptian-themed titles this catalogue actually contains.

Spinomenal vs the studios it competes with

Spinomenal fights in the high-volume independent-studio bracket, distinguished mainly by output speed rather than a single standout mechanic. Against our previously reviewed studios:

The honest read: Spinomenal is the most volume-driven studio on this comparison — where Playson spent a decade refining one mechanic and Wazdan built a genuinely distinctive player-facing feature, Spinomenal has instead optimised for a steady 1–3-releases-a-month cadence across recurring themes (Wolf Fang, Story of…, Book of…). That approach produces a genuinely large catalogue, but fewer standout titles per release than studios prioritising fewer, more polished games.

The game families, in depth

A catalogue organised almost entirely around recurring theme franchises rather than one signature mechanic. The full ranked list covers the rest.

The Wolf Fang series

Snowfall, The Polar Lights and at least two further entries — the same Arctic-wildlife cast reskinned across multiple releases, the clearest example of theme-recycling in the catalogue.

The Story of… series

Egyptian Darkness, Medusa II, Loki: Master of Illusions and further mythology-themed entries — a loose umbrella covering Egyptian, Greek and Norse mythology under a consistent naming convention.

The Book of… shelf

Book of Elves and other expanding-symbol entries competing directly in the industry’s single most crowded genre, the one Greentube and countless others also occupy.

The classic-fruit and Egyptian-mythology wings

Super Wild Fruits and Reign of Seth sit alongside dozens of similarly themed titles — evidence the catalogue leans heavily on a handful of proven, low-risk genres rather than spreading across genuinely distinct settings.

Spinomenal game mechanics & technology

Unlike several rival studios on this site, Spinomenal doesn’t centre its identity on one trademarked mechanic:

Standard genre templates, executed at volume

The bulk of the catalogue runs on well-established formats — expanding-symbol Books, featureless classic-fruit reels, straightforward free-spins structures — built reliably and quickly rather than engineered around a novel bonus feature. It’s the inverse of the bet Red Rake Gaming makes with a much smaller catalogue: fewer games, but at least one genuinely original mechanic in Orbital Reels.

Expanded Editions

Several flagship titles, including Majestic King, later ship in an “Expanded Edition” running more paylines than the original — a low-cost way to extend a proven theme’s commercial life without building an entirely new game.

Retro Gaming line

Spinomenal maintains a dedicated retro-gaming shelf on its own site, distinct from its main RMG catalogue — a smaller side project rather than a defining mechanic, but worth knowing about if researching the studio’s full output.

Spinomenal slots RTP: the real numbers

The defaults: a tight band around 95.5–96.3% across most of the catalogue — consistent with the wider industry standard, honestly published without a distinguishing multi-tier build system.

Volatility: mostly medium across the catalogue, in keeping with a studio optimising for broad casino-lobby placement rather than chasing the highest volatility ceilings; max win potential in the low-to-mid thousands is typical.

Release-cadence trade-off: a 1–3-titles-a-month output means less individual polish time per release than slower-shipping studios — worth factoring in when comparing Spinomenal’s catalogue depth against its per-title craft. Our responsible gambling guide applies as always.

From Tel Aviv start-up to 300-title catalogue

The arc that matters: two founders with social-gaming backgrounds built a studio optimised from day one for volume and distribution reach rather than a single breakout franchise — a decade later, that strategy has produced one of the largest catalogues on this site, distributed through major aggregators to hundreds of casinos, without the acquisition or leadership change several rival studios have gone through.

The people who built Spinomenal

Lior Shvartz

Shvartz co-founded Spinomenal in 2014 and continues to serve as CEO, having brought experience from social gaming into the real-money slots space at founding — a background that likely shaped the studio’s volume-first, broadly accessible approach to game design.

Omer Henya

Henya co-founded the studio alongside Shvartz and serves as CTO, overseeing the technical infrastructure that has let Spinomenal maintain a genuinely unusual 1–3-releases-a-month cadence for over a decade.

An unusually stable, unusually fast-shipping team

Unlike several studios on this site that have changed ownership through acquisition, Spinomenal’s founding team has led the company continuously since 2014 — stability paired with one of the industry’s highest sustained release rates.

Is Spinomenal fair? Licensing, regulation & the record

Checked against the Gambling Commission’s public register on 5 July 2026, re-verified 9 July 2026.

The licences. Panda Bluemoon Ltd (Israel) holds UKGC account 58209 with an active remote gambling software licence; SubTech Ltd (Malta) holds account 58210 with active remote gambling software and game host (casino) licences. Both have run continuously since 3 August 2022. Verify them yourself on the UKGC public register by searching “Spinomenal”.

The record. Clean on the UKGC side: no enforcement action against either entity that we can find, across a four-year UK licence history. It isn’t spotless everywhere, though — Sweden’s gambling regulator, Spelinspektionen, fined Panda Bluemoon Ltd SEK 700,000 in January 2024 after the studio’s games became accessible on an unlicensed Swedish-facing website during a contract breach by a third-party distributor, Mikai Tech Ltd, covering the second half of 2023. Panda Bluemoon corrected the access issue quickly and cooperated with the investigation, and the case doesn’t touch its UK licence, but it’s a real, documented regulatory action worth stating plainly rather than glossing over.

So is it fair? Yes on the UK evidence — certified RNG across the catalogue, a clean UK licensing file since 2022, and published RTP figures consistent with the wider industry standard. The Swedish penalty above is about distribution-channel control rather than game fairness itself, but it’s the one blemish on an otherwise clean four-year regulatory record.

The biggest Spinomenal wins

A high-volume independent studio whose biggest documented numbers show up in catalogue scale and release cadence rather than headline jackpot-network records. Documented context only:

Beyond the reels

The corners of the story the ranking competitors never reach:

Social gaming roots

Both founders came from social gaming before Spinomenal, a background distinct from the land-based-arcade or traditional-studio pedigrees behind several other providers on this site — arguably shaping the studio’s broadly accessible, volume-optimised design philosophy from the start.

A retro-gaming side project

Beyond its main real-money catalogue, Spinomenal maintains a dedicated retro-gaming section on its own site — a smaller, less commercially central initiative most player-facing reviews never mention.

One of the industry’s fastest sustained release cadences

Shipping 1–3 new titles most months for over a decade, without slowing, is a genuinely unusual pace — faster than Wazdan’s or Playson’s more measured release schedules, though the trade-off shows in how few Spinomenal titles achieve the standout status of those studios’ headline franchises.

The company behind the games

Beyond the UKGC and Malta Gaming Authority (RN/025/2024) licences already covered above, Spinomenal’s own site lists a wider compliance file than most player-facing reviews mention: an ISO 27001 information-security certification, BMM Testlabs game certification, a Hellenic Gaming Commission listing in Greece (HGC-000000098-MN), and a Romanian ONJN Class II licence. The studio is also listed as a supporter of GambleAware, Britain’s leading gambling-harm-reduction charity. None of that is unusual for a studio operating across this many regulated markets, but it is a genuinely broader compliance footprint than the single UK licence file most competitor review pages stop at.

On the commercial side, 2025 was a genuinely busy year for new distribution reach rather than any single headline deal: agreements or go-lives with Rank Group (Spain), Starcasino (Netherlands), Betsson Georgia, Caesars Entertainment (New Jersey), Rush Street Interactive’s BetRivers (New Jersey) and Hard Rock Bet (New Jersey) all landed within a few months of each other, on top of the studio’s existing aggregation relationships with SoftSwiss, EveryMatrix, iForium and Slotegrator. It’s the clearest sign that Spinomenal’s growth strategy right now is about reaching more regulated markets through more operators, not about slowing its release cadence to chase fewer, bigger titles.

New Spinomenal slots: what’s launched for 2025–26

The state of Spinomenal right now: still shipping at its established 1–3-titles-a-month pace, with no signs of slowing after a decade, and backing that up with a busy run of distribution news through 2025 — new content deals with Rank Group covering Spanish expansion (June 2025), Starcasino in the Netherlands (July 2025), Betsson Georgia (July 2025), and a Caesars Entertainment go-live across its New Jersey online casino brands (July 2025), on top of earlier 2025 agreements with Rush Street Interactive’s BetRivers and Hard Rock Bet in New Jersey. This section refreshes with every significant launch.

3 Irish Treasures — the newest release

Spinomenal’s most recent release is 3 Irish Treasures, launched 2 March 2026 as an addition to the studio’s Hold & Hit portfolio: a 5×3, 10-payline slot set in an Irish-folklore woodland, built around four bonus-symbol types (Bonus Boost, Bonus Multi, Bonus Collect and a standard Bonus) that combine into a Grand Jackpot worth 3,000x the stake. Spinomenal’s own game sheet lists four selectable RTP tiers — 89.14%, 92.07%, 94.28% and 96.11% — consistent with the rest of the catalogue’s published range. It’s too new for independent player-win verification, which is why it sits in this section rather than the top-10 list above.

All ship with published figures. Paytable first, always.

What players actually say

From forums where Spinomenal is discussed as a reliable, if unremarkable, high-volume studio — our words, cons intact.

The love: Majestic King draws consistent praise as the studio’s clear standout, players credit Spinomenal’s steady release cadence for keeping its catalogue feeling current, and the studio’s honest, unremarkable RTP band draws no complaints on the transparency front.

The gripes, plainly: the heavy reuse of themes (four-plus Wolf Fang entries, a crowded Egyptian-mythology shelf) draws fair criticism for feeling repetitive across the wider catalogue, several titles are seen as competent-but-forgettable next to headline releases from more selective studios, and Spinomenal’s UK lobby presence remains thinner than several larger names on this site despite its genuinely large catalogue. All fair, and Majestic King loyalists remain unmoved.

Which Spinomenal slot should you play?

The thirty-second version of everything above:

Our verdict on Spinomenal

Slot Providers score: 6/10 — a genuinely high-output, stably-run studio with one clear flagship in Majestic King, docked for a catalogue that leans heavily on recycled themes and rarely reaches the standout quality of more selectively-releasing rivals on this site.

Spinomenal suits operators and players who want broad genre coverage from one reliable supplier, and fans of Majestic King specifically looking for similar savannah or mythology-themed titles. Look elsewhere if you want a studio built around one genuinely distinctive mechanic — Wazdan’s Volatility Levels or Playson’s Hold and Win mastery both offer more — or a more tightly curated, less repetitive catalogue.

Spinomenal FAQs

Who owns Spinomenal?

Spinomenal has been independently owned since its 2014 founding by Lior Shvartz (CEO) and Omer Henya (CTO), both still leading the company — no acquisition or ownership change since founding.

Is Spinomenal fair, or are its games rigged?

Both Spinomenal UKGC entities (accounts 58209 and 58210) hold active licences with clean UK records since 2022, certified RNG across the catalogue, and consistent published RTP figures. Panda Bluemoon Ltd was fined by Sweden’s regulator in 2024 over a distributor’s unlicensed-access breach — a real but non-UK, non-fairness issue; see our full regulation section for the detail.

What is the best Spinomenal slot?

Majestic King is the studio’s clearest flagship, with Book of Elves and Werewolf: The Hunt close behind. Our full ranked ten, with reasoning, is above.

How many games does Spinomenal have?

The catalogue passed 300 titles as of 2026, built up over a decade at a sustained pace of 1–3 new releases most months.

What are the newest Spinomenal slots?

Where can I play Spinomenal slots in the UK?

Videoslots, LeoVegas, MrQ, Casumo and PlayOJO all carry a cross-section of the Spinomenal catalogue, though its UK lobby presence is thinner than its 300+-title catalogue might suggest since much of the distribution runs through aggregation deals rather than direct casino partnerships. See our casinos section for the full breakdown, and always verify any operator on the Gambling Commission register before depositing.
