Description
Core Gameplay
You are shown the floor plans of a building’s superstructure (columns, beams, core walls – decorative representation). Find differences in structural elements. Each correct find adds a beam to your stack. The game does not teach real engineering.
Level & Content Design
Thirty‑five levels representing different structural grids (e.g. 3×3, 4×4, radial). Differences include missing beams, changed column thickness, or shifted core positions. Difficulty progression is steep. No updates.
Visuals & Experience
Technical drawing style with grey and white lines. No distracting colours. The game supports mouse wheel zoom and pan. Performance is stable on most devices.
Key Features
A “snap to grid” toggle helps align your view. No hints, but a “check” button tells you how many differences remain (but not where). Unlimited level retries.
User Value
Develops systematic scanning across regular patterns. The abstract, technical style appeals to players who enjoy logic puzzles.
Usage Scenarios
Deep concentration sessions, puzzle competitions, or as a brain‑teaser for engineering hobbyists (hobby only).
