Skull Carnival by Zillion Games: headline RTP 95.25%, Medium volatility, max win x1 300.
An RTP of 95.25% means a house edge of 4.75% — the expected cost is 4.75 units per 100 staked over the long run, whatever a single session does.
Skull Carnival sits at medium volatility — a middle profile where wins are neither rare nor frequent enough to dominate a session.
The advertised ceiling is x1 300. 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 17% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Released 2025-09-25. Release date matters for RTP: newer titles are more likely to ship with several configurable builds, which is what lets two casinos price the same game differently.

Yes. Skull Carnival 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.
Skull Carnival is a Zillion Games 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.
