Spinomenal was founded in 1998 and is headquartered in London, UK with approximately 614 employees. Parent company: Independent. The studio currently has 300+ titles in active catalogue.
Spinomenal operates under MGA, UKGC, Gibraltar regulated-market licences. RNG and game-fairness certification by independent labs such as eCOGRA, GLI (Gaming Laboratories International) and iTech Labs.
Provider-side licence numbers should be cross-checked against the regulator's public register. A provider supplying a casino that is licensed in a given regulated market typically needs an equivalent provider-side licence to operate legally there. Spinomenal's licence list is published in the regulatory section of its corporate site.
Demi Gods cluster (I through V), Majestic King, Wolf Fang, Book of Demi Gods cluster, Story of Hercules cluster, 9 Coins, Vampire Princess of Darkness, Fire and Steel: Battle of Eternity, Gold Express, Money Cart 4.
Spinomenal's catalogue size: 300+ titles. Average RTP across the catalogue: 94%. Jackpot record on Spinomenal titles is $10M+.
94.0%–96.3% typical
The operator-selectable RTP variance is a material issue across several studios in the industry. The BillyBets casino review (3.8/5) flagged Pragmatic Play titles configured at the 94% option rather than the 96% headline. Verify in the casino-side game-info popup, not the provider's headline marketing material.

Use the casino-reviews index to find which top-rated casinos carry this provider's catalogue in your jurisdiction.
Yes — all modern Spinomenal releases ship as HTML5-first with both portrait and landscape orientation support. Titles render natively in iOS Safari and Android Chrome without app installs.
Megaways is a Big Time Gaming patent licensed to most tier-one slot studios. Whether Spinomenal licenses Megaways depends on the studio's current BTG agreement — verify by checking the Spinomenal catalogue for "Megaways" in title names. Notable Megaways licensees include Pragmatic Play, Blueprint Gaming, Red Tiger, ELK Studios and Yggdrasil.
Spinomenal's documented jackpot record is $10M+, suggesting the studio operates a network or in-game progressive framework. The largest industry progressive networks are Mega Moolah (Games Global, custodian of Microgaming's lineage), Drops & Wins (Pragmatic Play), Daily Jackpots (Red Tiger), Jackpot King (Blueprint) and Dream Drop (Relax Gaming).
Spinomenal's release cadence is high (5+ titles/month) and the Demi Gods cluster is a long-running franchise. Less critical recognition than Hacksaw or Nolimit but solid CEE/MENA market presence.
Spinomenal operates under MGA, UKGC, Gibraltar regulated-market licences. RNG and game-fairness certification by eCOGRA, GLI and iTech Labs. The full licence list and certification details are published in Spinomenal's regulatory section on its corporate site.
Casino-carriage depends on the provider's licence portfolio (MGA, UKGC, Gibraltar) and aggregator-platform distribution. Major aggregators (Relax Silver Bullet, Yggdrasil GATI, Pragmatic distribution) carry second-tier studios into operator lobbies on shared infrastructure. The Gambledin catalogue confirms Spinomenal carriage at top-rated brands.

Yes at most casinos — Spinomenal titles ship with a demo mode that lets you play with virtual credits. Demo mode is restricted in some regulated markets (UKGC, Italian ADM) where the casino must verify your age before showing the game. Check the casino game library for the "demo" or "play for free" option.
Yes — most Spinomenal slots accept stakes from €0.10–€0.20 per spin (some from €0.01). This makes the studio accessible to recreational players; max stakes are typically €100–€500 per spin for higher-roller play within UKGC's £5 online slot stake cap where applicable.
Many Spinomenal titles participate in network tournaments hosted by participating casinos (free-to-enter or buy-in with prize pools). Casino-specific leaderboard mechanics integrate Spinomenal games via standard slot-tournament APIs. Check your casino's promotions page for current Spinomenal tournaments.
Release cadence varies — top-tier studios release 10–15 titles per month; boutique studios 1–3. Spinomenal's catalogue currently sits at 300+ titles, indicating release cadence approximately reflective of catalogue growth over the studio's operating years.
Many modern Spinomenal titles include a "bonus buy" option (typically 60x–120x stake to instantly trigger the bonus round). Bonus-buy is prohibited under UKGC and several other tier-1 regulator rules, so the feature may be disabled on UK-facing versions of Spinomenal titles. Check the game-info popup for availability.
Yes — Spinomenal titles ship with multi-language UI (typically 15+ languages including English, German, Spanish, Portuguese, Italian, Russian, Japanese, Mandarin) and accept any casino balance currency. Localisation is set automatically by the casino lobby.
Variance varies by title rather than across the whole Spinomenal catalogue. Spinomenal publishes per-title volatility ratings (low / medium / medium-high / high) in the game-info popup. Sort by volatility in your casino's slot lobby filters to find Spinomenal titles matching your variance preference.
Sometimes — Spinomenal ships several titles with multiple operator-selectable RTP options (e.g. 94% / 95% / 96% / 97%). The operator chooses which RTP to enable. Always verify the actual configured RTP in the casino-side game-info popup, not the Spinomenal headline (94%).
Selectively — Spinomenal games are licensed to social casinos (free-to-play with virtual currency) and sweepstakes casinos (US-facing prize-redemption model) on a per-deal basis. The full Spinomenal catalogue may not be available in social/sweepstakes formats; check the specific operator's game library.
Demi Gods cluster (I through V), Majestic King, Wolf Fang, Book of Demi Gods cluster, Story of Hercules cluster, 9 Coins, Vampire Princess of Darkness, Fire and Steel: Battle of Eternity, Gold Express, Money Cart 4.
Studios in the Spinomenal segment increasingly license branded IP (TV, film, music) for select releases. Spinomenal-specific branded titles vary; check the catalogue or studio press releases for current IP partnerships. Branded slots typically carry licence-cost overhead reflected in stake/RTP economics.
No — Spinomenal games are HTML5 client/server: the random-number-generation runs on Spinomenal's certified RNG server, not in the browser. Without network connectivity, no gameplay is possible. This is true of all certified casino slots — offline play would invalidate RNG fairness.
Yes for modern titles — Spinomenal ships HTML5-first releases with full feature parity between desktop and mobile (portrait/landscape orientation, all bonus features, full betting range). Legacy titles (pre-2018) may have reduced mobile feature sets; check the game-info popup.
Progressive jackpots accumulate from a percentage of each bet (typically 1–5% of stake) placed across all participating casinos. The pool grows until won; on a jackpot hit, the pool resets to a seed amount and resumes growing. Spinomenal's specific progressive networks are documented in each jackpot title's rules.
Most Spinomenal titles are accessible to new players — modern slot UX (auto-spin, in-game tutorials, hover-to-explain pay tables) lowers the learning curve. High-variance titles (Nolimit City-style mechanics) are better suited to experienced players who understand bankroll management for long dry spells.
