Mental Rotation 回転

Logic · 600 levels in the app

Train your spatial reasoning by mentally rotating 3D shapes and identifying which option matches the reference.

How to play

Study the reference shape shown on screen. It may be rotated or mirrored. Choose the option that, when rotated, would look identical to the reference.

Objective

Correctly identify the matching rotated shape as quickly as possible.

Strategy tips

  1. Pick one distinctive feature of the shape (a protruding arm, a notch, an asymmetric block) and track only that part as you mentally rotate: don't try to move the whole shape.
  2. Rotate in 90° steps. Ask: "after a quarter-turn left, where does my feature land?" Compare with each option at each step.
  3. Eliminate mirror images first. A reflected shape can never match no matter how you rotate it: check for that property early to halve your options.
