Manufacturers run several branded families at once. These are the rest of Aruze Gaming's.
Why there's no single "Ultra Stack" machine
Manufacturers ship a successful title as a family, not one box. Each entry above is a distinct game with its own maths, artwork and cabinet — and casinos install whichever versions they license. Asking for "Ultra Stack" on a casino floor can mean any of these 7.
The same applies to payback: there is no single RTP for the series, or even for one title — manufacturers ship multiple par versions per game and the operator picks one.
