Endorphina

Endorphina is a Prague studio with 230 games in our catalogue, and the first thing the numbers show is how little they vary. Where most studios spread their RTP across several points, Endorphina builds almost everything to the same target and leaves it there.

The tightest RTP band we measure

218 of the 230 games return 96% or more. Five sit between 95% and 96%. Seven sit below 95%. The whole catalogue fits between 89.83% and 96.15%, and the median is 96.05%.

To see how unusual that is, compare the top of the band: the single highest RTP Endorphina publishes is 96.15%, on Football:2022. Other studios in our catalogue reach 97%, 98% and — on table games — 99%. Endorphina has a ceiling and stays under it.

The seven exceptions

Satoshi’s Secret is the outlier by a distance — more than six points below the studio’s own norm, and 2.3 points below the next-lowest game it makes. If you play one Endorphina title knowing its RTP, make it that one.

What the studio does not publish

Two gaps, and both are total:

• Release year: zero of 230. Not one Endorphina game page states when the game came out. We cannot tell you whether a title is from 2015 or from last month, and our pages leave the row empty rather than guess from a copyright notice.
• Maximum win: zero of 230. No ceiling multiplier anywhere. The number most players check first does not exist on the manufacturer’s own pages.

What it does publish

• Minimum and maximum bet on all 230, from €0.01 at the bottom to €200 at the top
• The paylines and features on 219 — “25 paylines; Wild, Risk Game, Scatter” and variations of it
• The grid, the volatility and the theme on almost all of them

So the disclosure is real, it is just aimed at a different question. Endorphina tells you what the machine is and what it costs to pull; it does not tell you how high it can go or when it was built.

The dice versions, and why there are 31 of them

Thirty-one games in the catalogue are named ”… Dice” — Asgardians Dice, Ancient Troy Dice, 100 Zombies Dice — and 29 of those have a non-dice twin in the same catalogue. They are not a separate game family. They are the same slot with the card symbols replaced by dice faces, built for the Belgian market, where dice games sit under a different licensing regime from slots.

The mechanics carry across: Asgardians Dice is a 5×3 grid with 25 paylines and an RTP of 96.07%, which is within a tenth of a point of the version it was cloned from. If you have played one, you have played the other.

⚠️ Our catalogue currently classifies these 37 dice titles under the same label as crash games, which is wrong — a 5×3 grid with 25 paylines is a slot whatever the symbols look like. That is a fault in our data, not in the studio’s, and it is on the list to fix.

Volatility, spread across the catalogue

More than 60% of the catalogue is medium-high or above. Combined with a hard ceiling at 96.15%, that is a specific profile: sessions that swing, returning to a number that is never generous and rarely poor.

No demos, and we say so

⚠️ None of the 230 Endorphina games has a demo you can open here. The studio does not expose a public demo launcher, so our Endorphina pages are specification sheets rather than places to play. We would rather say that than show a button that goes nowhere.

Where our numbers come from

Every figure is read from Endorphina’s own game pages at endorphina.com and recorded, with the source URL, on each slot page. The catalogue was ingested in August 2026 and each entry says so. Where the studio publishes nothing — the release year and the maximum win, on all 230 — our pages say “not published by the manufacturer” instead of filling the gap from an aggregator.
