Poseidon Xtreme by spinmatic: headline RTP 99.00%, Low-Med volatility, max win x90 000.
An RTP of 99.00% means a house edge of 1.00% — the expected cost is 1.00 units per 100 staked over the long run, whatever a single session does.
Poseidon Xtreme 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 x90 000. 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 100% 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 0.01 to 0.5 per spin on a 5 layout with fixed betways.
This title is tagged Gods. A theme is art direction, not maths — two games sharing every symbol can be priced differently.

Yes. Poseidon Xtreme 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.
Poseidon Xtreme is a spinmatic 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.
