Where Ultra Stack™ – Poseidon sits in Aruze Gaming's range
Ultra Stack™ – Poseidon is part of Aruze Gaming's Ultra Stack line, which runs to 7 documented titles. Manufacturers ship a hit as a family rather than one box, so entries in a series share branding and often a bonus structure while carrying different maths.
What's the RTP of Ultra Stack™ – Poseidon?
There isn't one number — and any site quoting you a single figure is describing a different product.
Manufacturers ship the same title in multiple par versions, commonly spanning roughly 85% to 96%. The casino chooses which one to install, and that choice is not disclosed on the machine. Nevada regulation only sets a floor: every wager must theoretically return at least 75%.
What regulators actually publish is hold percentage — realised performance after player behaviour, aggregated by region and denomination. It is never broken out by game title. So the honest answer for any land-based machine is a range plus an unknown configuration, not a single figure.
Figures quoted elsewhere for this title are almost always taken from its online version, which is a different product with a different maths model.
Where to play
We don't yet have verified floor placements for this machine. Our casino cross-reference covers 442 properties, but only through IGT's public linked-progressive data — which doesn't reach Aruze Gaming titles. We would rather show nothing than guess.
