Gary wrote and asked for a puzzle made with square pieces, and so this is it.
It is very tough as all the pieces are perfect squares. You’ll have to rely 100% on the image as there are no edge shapes to give it away.
Just to take a little bit of the heat off, I did make each size with a few less pieces, but the tough version still has 192 pieces.
Enjoy, and if it’s too frustrating, blame Gary!
