Mystery Rainbow by Playnetic: headline RTP 96.00%.
An RTP of 96.00% means a house edge of 4.00% — the expected cost is 4.00 units per 100 staked over the long run, whatever a single session does.
Against our catalogue the number is below the median of 96.13%, higher than 28% 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 0.4 to 500 per spin on a 5 layout with fixed betways.

Yes. Mystery Rainbow 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.
Mystery Rainbow is a Playnetic 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.
