Why are Jigsaw Puzzles so popular with little people and also grown ups? How does puzzling fun begin? Here are some interesting facts:
Originally, all jigsaws were made out of wood, a picture was drawn onto a flat piece of wood, small shapes were then cut out with a jigsaw - hence the name.
It makes sense that puzzle pieces are often used as symbols for problem solving - have you spotted them in the Wikipedia Logo or in logos of Autism related charities (due to the puzzling nature of Autism)?
