What this test measures

This game measures spatial reasoning: rotating a solid in your head and matching it to a 2D view. You practice viewpoint change, not memorizing a single picture.

FAQ

How is the score counted?
Your score is the streak of correct viewpoint matches in one run.
Do I rotate the object myself?
No. Read the requested angle and choose the picture that matches that view.
What if two answers look similar?
Check edges and holes. Small features often decide the correct face.
Is this a clinical visuospatial test?
No. It is a 3D puzzle game, not a diagnostic tool.
