Description
Core Gameplay
Black‑and‑white line‑drawn floor scenes are presented in pairs. Find five subtle differences. Each correct find is automatically circled and scored. After all five are found, the current floor is stacked onto a left‑side tower.
Level & Content Design
Twenty linear levels with exclusively monochrome artwork. Differences involve line thickness, missing details, or small shape changes. Difficulty remains low to moderate. No future updates are planned for this edition.
Visuals & Experience
Pure black‑and‑white with no shading. The clean linework helps focus on structural differences. No music – only subtle sound effects for feedback (can be silenced).
Key Features
No time limit. Unlimited attempts per level. A “show me one” button highlights a random undetected difference, but using it marks the level as “assisted”. Progress is saved per level.
User Value
Trains visual discrimination without colour distractions. The calm, silent atmosphere suits people who prefer quiet games.
Usage Scenarios
Evening relaxation, waiting for appointments, or practising focus in a low‑stimulus environment.
