Where Stacks on Stacks sits in Castle Hill Gaming's range
Castle Hill Gaming lists 10 denominations for this title. Denomination is one of the strongest predictors of theoretical return on a casino floor — penny games generally carry a lower percentage than dollar games, across essentially every manufacturer.
Mechanically it is a 3 reels game. Pay-line games award only on defined line patterns, which typically means fewer but larger hits than an equivalent ways-to-win title.
Stacks on Stacks is a Class II machine — that changes the question
Under the Indian Gaming Regulatory Act of 1988, Class II covers bingo and games that are technologically aided bingo. This machine is legally a bingo terminal. Every play enters a bingo game shared with other players on the same system, and the outcome is decided by that draw — the spinning reels are an animation that reveals a result already determined.
That is why "what is the RTP of this machine" doesn't map cleanly onto a Class II title. Return depends on the bingo pool, the prize schedule and how many terminals are competing in each draw — none of which live inside this cabinet.
Class II is what allows tribal properties to operate without a Class III compact with the state, which is why the same game title often exists in both a Class II and a Class III build with different maths behind identical artwork.
If you have played Stacks on Stacks at two properties and it felt different, this is frequently why — you may have been playing two different regulatory builds of the same title.
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 Castle Hill Gaming titles. We would rather show nothing than guess.

Class II titles run on a shared bingo draw rather than an independent RNG — a different product category, not just a different game.
