Why this gift works
The Hanayama Cast Marble Puzzle is a cast-metal sphere with unusual cuts across its surface that comes apart into four pieces. It was designed by Oskar van Deventer and Bram Cohen and is made by Hanayama of Japan; the US BePuzzled box rates it Level 4, while Hanayama's own site now lists it as Level 5, Expert. Retailers describe it as easy to take apart and hard to put back together. It is rated for ages 12 and up.
Metal puzzles like this live on a desk and get picked up in idle moments, and a polished sphere looks more like an ornament than a toy. It is a small, lasting gift for anyone who likes a challenge.
Who is this gift for?
Great for
- A puzzle lover who has everything
- A colleague who likes brain teasers
- A teen who enjoys a challenge
Think twice if
- They frustrate easily
- The gift is for a young child
The catch
Difficulty ratings differ between the US box and Hanayama's site, it has small parts, and several Amazon listings exist for the same puzzle, so check the link.
Skip for young children, or someone who gets frustrated by very hard puzzles.
