This puzzle is called “wooden fractal puzzle“, but I’m not sure why it’s fractal …? This was the 5×5, easy version … when I took it out, Ash thought it looked hard — I thought it was going to be easier than “Wriggle” and it was. Look for the odd piece corners that can only fit together, and build from there ….
I’m calling this one laser-cut, because of the tell-tale scorch marks on the wood ….
