Jigsaw 29 is a devious packing puzzle designed by Yuu Asaka with only one possible solution.
There are 29 pieces that you must try and fit within the frame. Once you start off it seems it may be simple but you’ll soon discover five corner pieces! With only one solution you need to fit all the pieces into the frame with no gaps.
This is the Hanayama version which is slightly smaller than those made by Yuu himself. This measures 100 x 100mm.
