Spinomenal

Spinomenal has the largest catalogue we list from any single studio: 644 games, all of them slots. And almost every one of them exists in four different versions.

Four RTP settings, and the casino picks

631 of the 644 games publish more than one RTP, and unlike most studios that do this, Spinomenal settles on a consistent shape: 624 of them have exactly four settings. Here are the five most common ladders:

There are 67 distinct ladders in total, and the pattern barely varies: a headline in the mid-nineties and a floor somewhere under 90%.

What that costs

Take the first row. At 95.42% the house keeps €4.58 of every €100 staked. At 88.85% it keeps €11.15 — nearly two and a half times as much, in the same game, with the same graphics and the same paytable.

⚠️ This is the single most important thing to know about Spinomenal games. The number on our page is the top of the ladder, because that is what the studio leads with. The number in your casino may be three rungs down, and the game will look identical either way.

How to check

Open the game’s information panel — the RTP is normally on the last page — before you spin. If it does not match, you are on a reduced build. We publish the whole ladder for every title precisely so that the comparison is possible.

The rest of the disclosure is thin

Against 631 games with published RTP configurations, the other rows are mostly empty:

No Spinomenal game in our catalogue carries a release date, a hit rate or a demo you can open here. Where the studio publishes nothing, our pages leave the row empty rather than filling it from an aggregator.

The Book of everything

The catalogue’s spine is a very large family of book-style games — expanding symbols, ten free spins, one special symbol chosen at the start. Book of Aphrodite: The Lovespell is a representative one: 96.01% at the top of its ladder and a 10,000× ceiling, which is also the highest ceiling anywhere in the Spinomenal catalogue.

That last detail is worth noticing. Where other studios push ceilings to 25,000× and beyond, Spinomenal’s maximum is 10,000×, and 73 games are all that publish one at all.

The band, measured across all 644

RTP runs from 93.65% to 96.85% at the top of each ladder — a narrow range by the standards of this catalogue, which makes the four-rung structure underneath it the only variable that really moves.

Where our numbers come from

Every figure is read from Spinomenal’s own game pages and recorded, with the source URL, on each slot page. The catalogue was ingested in 2026 and each entry says so. Where the studio publishes nothing — the year, the hit rate, and the maximum win on 571 of 644 games — the row stays empty.
