Mental Rotation· Advanced

Goal

Find the shape that matches the original when rotated. Answer quickly and accurately for a higher score.

How to Play

  • Compare the reference shape at the top with the 4 options below
  • Tap the option that matches the reference shape when rotated
  • Flipped (mirrored) shapes are wrong — only rotation counts!

Core Rule: Rotation Only

A rotated shape is correct, but a mirrored (flipped) shape is wrong.

NG

Core Rule: Verify Same Shape

The same shape at a different angle is correct. A similar but different shape is wrong.

OK= OK
NG

Completed Example

  • Tap the choice that matches the original shape at the top. The correct answer is a rotated version of the original.
  • Each question has a time limit. If time runs out, it counts as incorrect.
  • Mirror images (horizontally flipped) are incorrect. Distinguish between rotation and reflection.

Tip

  • Focus on distinctive protruding parts to quickly determine the rotation direction
  • Mentally rotate the shape slowly — you'll get faster with practice
  • Mirrored shapes have protrusions pointing in the opposite direction

Mental Rotation, developed by Shepard & Metzler (1971), is a core paradigm of spatial cognition where response time increases linearly with rotation angle.
