Fafnir's Key by Platipus: headline RTP 96.15%.
An RTP of 96.15% means a house edge of 3.85% — the expected cost is 3.85 units per 100 staked over the long run, whatever a single session does.
Against our catalogue the number is above the median of 96.13%, higher than 52% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.

Fafnir's Key is a Platipus 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.
