The puzzle consists of single plane frame and 4 identical pieces. Some part of the pieces are actually made from the same wood as the frame and so when assembled they actually look like part of a larger frame.
When you first pick it up there seems to be a lot of movement in the pieces inside the frame; the pieces will even rotate; but there doesn't appear to be any way to get them out. With the right sequence of moves, level 18.104.22.168, and even rotational moves in the correct place, you can get all 4 pieces out of the frame.
There is only 1 possible solution. Rotational moves do not mean force. A rotational move means get the piece or pieces in the correct spot and there will be plenty of space to rotate.
Puzzle designed in March 2013 by Osanori Yamamoto and very well crafted by Pelikan workshops to create a very smooth moving puzzle that feels really good to sit and fiddle with.
