Why this walkthrough is organized by room
Old Sins does not present conventional numbered levels. Complete routes consistently divide Waldegrave Manor into the Foyer, Study, Curiosity Room, Kitchen, Maritime Room, Garden, Japanese Gallery, Art Studio and Attic ending. That stable structure keeps each search result tied to a recognizable place and item state.
How the routes and images were checked
Every room was cross-checked against AppUnwrapper, Neoseeker, a complete Steam community route and a full PC playthrough. Each card uses a separately captured frame from the corresponding room or mechanism; a contact sheet and file hashes prevent repeated generic covers.
