Kupala by Spinomenal: headline RTP 95.60%, max win x500 000.
An RTP of 95.60% means a house edge of 4.40% — the expected cost is 4.40 units per 100 staked over the long run, whatever a single session does.
The advertised ceiling is x500 000. Max win figures describe the tail of the distribution, not a realistic target: on most games with a ceiling this high the probability per spin is below one in a million.
Against our catalogue the number is below the median of 96.13%, higher than 20% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Stakes run from 1 to 10 per spin on a 5 layout with fixed betways.
Kupala is one of 580 Spinomenal titles in our catalogue, a studio averaging 95.34% RTP across the games we could verify.

Kupala has a published RTP of 95.60%, a house edge of 4.40%. We have not yet found a casino serving it at a different RTP build.
Yes. Kupala has a free demo with the same mathematics as the real-money version — the only thing that changes is that the balance is not yours. A demo cannot tell you the RTP build a particular casino serves.
Kupala is a Spinomenal game, so the outcome is produced by the studio's certified RNG rather than by the casino, and it is not provably fair in the cryptographic sense — you cannot recompute a spin from a seed. What the casino does control is which RTP build it serves. That is the real variable, and it is measurable.
