The Hanayama Donuts puzzle is a fun mid-range puzzle.
The two pieces in this one look like donuts and the aim is to seperate and then reassemble them.
The clue for this one is to try and imagine the inner structure and use the rings’ division lines as a hint.
The unique movement for opening this one is pleasantly suprising.
A level 4 out of 6 in the Hanayama range.
