Zombies by Peter & Sons: headline RTP 96.52%, Low-Med volatility, max win x1 200.
An RTP of 96.52% means a house edge of 3.48% — the expected cost is 3.48 units per 100 staked over the long run, whatever a single session does.
Zombies is a low-med volatility game: wins land often and small, which makes the bankroll curve smooth without changing the long-run cost.
The advertised ceiling is x1 200. 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 85% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Hit ratio is 26.6%, meaning roughly 27 spins in 100 return something — most of them less than the stake. A hit is not a win.
Features: In-game Freespins.

Zombies has a published RTP of 96.52%, a house edge of 3.48%. We have not yet found a casino serving it at a different RTP build.
Zombies is a Peter & Sons 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.
