Icy Rockfall X25 by Mascot Gaming: headline RTP 94.80%, max win x2 500.
An RTP of 94.80% means a house edge of 5.20% — the expected cost is 5.20 units per 100 staked over the long run, whatever a single session does.
The advertised ceiling is x2 500. 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 13% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Released 2024-12-24. 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.
Icy Rockfall X25 is one of 116 Mascot Gaming titles in our catalogue, a studio averaging 95.39% RTP across the games we could verify.

Icy Rockfall X25 is a Mascot Gaming 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.
