Plate 15 / 17 · Medium

Which option is the same shape, only rotated?

Tap the option you think is right, or show the answer.

Show the answer

Option 1 is the original figure turned a quarter turn counterclockwise.

How to solve it

  1. Pick a landmark: the marked cell or the end of the longest arm.
  2. Turn the figure in your head and watch where that landmark goes, and which side the other cells end up on.
  3. Turning the figure a quarter turn counterclockwise gives option 1.
  4. Each of the other options is a mirror image: flipping it over would match, but no turn does.

About this puzzle

Medium puzzles use larger flat figures of six cells, some without a marked cell, so there is less to anchor on. It was generated by the same engine that builds the IQ Octopus test, from a fixed seed, so it stays the same every time you visit. In the real test, items like this are generated fresh for every attempt.
