Dwarf Mine by Yggdrasil Gaming: headline RTP 96.80%, Medium volatility, max win x488 025.
An RTP of 96.80% means a house edge of 3.20% — the expected cost is 3.20 units per 100 staked over the long run, whatever a single session does.
Dwarf Mine sits at medium volatility — a middle profile where wins are neither rare nor frequent enough to dominate a session.
The advertised ceiling is x488 025. 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 above the median of 96.13%, higher than 93% 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 0.25 to 125 per spin on a 5 layout with fixed betways.
Dwarf Mine is one of 93 Yggdrasil Gaming titles in our catalogue, a studio averaging 95.44% RTP across the games we could verify.

Yes. Dwarf Mine 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.
Dwarf Mine is a Yggdrasil 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.
