Rumble Ratz Hold the Cheese by Kalamba Games: headline RTP 94.92%, max win x5 120.
An RTP of 94.92% means a house edge of 5.08% — the expected cost is 5.08 units per 100 staked over the long run, whatever a single session does.
The advertised ceiling is x5 120. 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 14% 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 0.5 to 100 per spin on a 6 layout with fixed betways.
Rumble Ratz Hold the Cheese is one of 166 Kalamba Games titles in our catalogue, a studio averaging 94.90% RTP across the games we could verify.

Rumble Ratz Hold the Cheese is a Kalamba 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.
