Book of Lucky Jack The Lost Pearl by Spinomenal: headline RTP 96.01%, max win x10 000.
An RTP of 96.01% means a house edge of 3.99% — the expected cost is 3.99 units per 100 staked over the long run, whatever a single session does.
The advertised ceiling is x10 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 33% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Book of Lucky Jack The Lost Pearl is one of 580 Spinomenal titles in our catalogue, a studio averaging 95.34% RTP across the games we could verify.

Book of Lucky Jack The Lost Pearl 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.
