Water Blox by Peter & Sons: headline RTP 96.07%, Medium volatility, max win x7 500.
An RTP of 96.07% means a house edge of 3.93% — the expected cost is 3.93 units per 100 staked over the long run, whatever a single session does.
Water Blox sits at medium volatility — a middle profile where wins are neither rare nor frequent enough to dominate a session.
The advertised ceiling is x7 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 41% 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 21.3%, meaning roughly 21 spins in 100 return something — most of them less than the stake. A hit is not a win.
Features: Bonus Buy, Respin, In-game Freespins. Note that studios frequently ship the bonus-buy path at a different RTP than the base game, and the lobby rarely says which figure it is quoting.

Water Blox 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.
