Arrows Disappear Clearing Guide: Work From the Profile In
Read the outline of the Arrows Disappear structure, uncover hidden faces deliberately, and keep the final core easy to understand.
The profile contains the safest candidates
Look around the outside of the shape for arrows on exposed corners and faces. Their direction can be compared with the full outline, which makes their path easier to prove than the path of an interior piece.
A visible gap is not enough. Confirm that the arrow continues away from every layer of the group before selecting it.
Use each removal to uncover a new face
When an arrow disappears, inspect the surface that replaces it. That newly exposed piece may now have an outward route, or it may still point through the core. Decide from the current shape rather than the old one.
Turn the view after opening a larger gap. A different side can clarify overlaps and reveal a better point of entry into the next layer.
Reframe the small inner group
The core often looks busier than the original shell because several arrows overlap in a tight area. Center it and rotate slowly until each piece has a readable depth.
Continue choosing the outermost confirmed direction. One careful disappearance at a time keeps the final moves understandable.
