Mental Rotations

Pick the shape that's the same figure as the reference, just rotated.

How to play

A reference shape is shown alongside several candidate shapes. Only one candidate is the reference shape rotated — the rest are different figures or mirror images. Pick the true match.

• Mentally rotate the reference shape rather than the options.
• Watch out for mirrored shapes — they look similar but aren't valid rotations.
• Choose your difficulty before starting — higher difficulty uses shapes with more squares.

Why this matters

Mental rotation is a well-studied, distinct spatial ability from matrix reasoning — it's the specific skill probed by 3D block-rotation items on the Stanford–Binet's Visual-Spatial Processing factor, and one of the most reliably improvable cognitive skills with repeated practice in the research literature.
