Description
Core Gameplay
You are shown an original floor design and a revised version with nine changes. The changes are architectural in nature – moved walls, altered door swings, changed room sizes (decorative, not real engineering). Find all nine to complete the stack.
Level & Content Design
Forty‑five levels, each featuring a distinct architectural style (e.g. Bauhaus, Art Deco, Brutalist). Differences become extremely subtle after level 30, requiring pixel‑level inspection. No automatic updates.
Visuals & Experience
Highly detailed blue‑print inspired drawings with a sepia tint. Grid lines can be shown or hidden. The game has a zoom magnification of up to 400% without quality loss.
Key Features
A “ruler” tool that measures distances between objects – useful for spotting size changes. Up to five hints per level, each hint costs a small time penalty (15 seconds). No in‑app purchases beyond the base product.
User Value
Appeals to puzzle enthusiasts who enjoy architectural themes. The ruler tool adds a unique analytical dimension.
Usage Scenarios
Quiet hobby time, learning to notice subtle spatial changes (no professional claim), or as a gift for architecture enthusiasts.
