Series and notable games
Spinomenal builds its catalogue around franchises and reissues successful games with new mechanics or line counts. That makes the catalogue large but repetitive in theme.
- Demi Gods: the studio’s main mythology series, including Demi Gods II, Book of Demi Gods II and 1 Reel Demi Gods II. Review sites rate Demi Gods II at around 95% RTP with medium-high volatility and a top win of up to 5,000x.
- Book of Demi Gods II: a 5-reel book-style slot with an expanding symbol in free spins. Review sites list RTPs of about 95%–95.9% for the 50-line version, and a separate Demi Gods II 15 Lines edition is listed at 96.2%.
- Majestic King, Wolf Fang, Queen of Ice, Book of Aphrodite and Fairytale Beauties: further series that follow the same model of a base game plus spin-offs.
- 1 Reel titles: spin-offs of popular themes (for example 1 Reel Demi Gods II) built around a single reel instead of a full grid.
Book-style slots work by choosing one symbol to expand across the reels during free spins; our free spins features guide explains why this produces long dry spells followed by large wins.
Multiple versions of the same game
Spinomenal frequently releases the same theme in more than one configuration: different numbers of lines, different RTPs, or different bonus structures. For players this has two consequences:
- The game name in the lobby may not tell you which version you are playing. Open the rules screen to confirm lines and RTP.
- A review figure for one version does not apply to the others. Our guide on how to check a game’s RTP shows where to find the correct number.
Maths profile
Spinomenal’s default RTPs typically fall between 95% and 96.5%, slightly below the averages of studios such as Play’n GO or Pragmatic Play at their highest settings. Volatility is mostly medium to high, driven by expanding-symbol free spins and multiplier features. Many titles include a bonus buy where permitted. Read our volatility guide to match the volatility rating to your budget.
| Series | Format | Reported RTP range | Volatility |
|---|---|---|---|
| Demi Gods | Video slots, free spins | About 95%–96.2% by version | Medium–high |
| Book of … | Expanding-symbol book slots | About 95%–96% | High |
| 1 Reel | Single-reel spin-offs | Version-dependent | Medium |
| Majestic King, Wolf Fang | Animal-themed series | About 95%–96% | Medium–high |
Promotions inside the games
Spinomenal supplies operators with in-game tools such as tournaments and free-round campaigns. When a casino runs a provider tournament, the scoring rule (total win, biggest single multiplier or number of spins) decides whether small stakes can compete, and most events set a qualifying minimum bet. Read the terms before opting in; our casino tournaments guide explains the scoring models used.
How Spinomenal compares
| Provider | Founded | Licence | Release style | Typical RTP |
|---|---|---|---|---|
| Spinomenal | 2014 | MGA (SubTech Ltd) | Franchises with multiple versions | About 95%–96.5% |
| Endorphina | 2012 | MGA/B2B/404/2017 | Single releases, fruit and crypto themes | About 96% |
| BGaming | 2012 (brand 2018) | MGA/B2B/785/2020 | Slots plus casual games | 95%–97% |
| Yggdrasil | MGA licence 2012 | MGA/B2B/230/2012 | Proprietary mechanics, partner studios | About 96% |
The practical point for players is version control. With Spinomenal, a review figure, a streamer’s result or a forum RTP may refer to a different edition of the game from the one in your lobby. With studios that release one version per title, that risk is lower. Volatility is in line with other book-style suppliers: expect long stretches without the free-spins trigger and most of the return concentrated in the bonus round.
Availability for Australian players
On this site, 5 reviewed casinos list Spinomenal: DundeeSlots, Woo Casino, Cosmobet, Lucky Star and 1xBet. Lucky Star and 1xBet do not accept Australian residents, so 3 of the 5 are open to Australians. The list is on casinos with Spinomenal games. Spinomenal titles are also distributed through aggregators, so casinos that do not list the provider separately may still carry individual games. Demo versions are usually offered in casino lobbies; availability after login depends on the casino’s country settings.
