This is an interesting all hardwood puzzle from our shop in an attractive format. It was designed by famous Dutch puzzle designer Niek Neuwahl in the 1990's.
You are given 5 pcs that make a square, PLUS an extra small square piece embedded within the largest piece . You goal is to remove the small square and place it somewhere else into the puzzle and still use all the pieces! Looks impossible, but of course there is a way...
