About this puzzle
Medium puzzles use the same side-count rule with a fresh set of figures; the rule changes at the hard level. 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.
