Puzzles

Anirud is very fond of jigsaw puzzles. He has crossed the stage of solving 6, 12 and 18 piece puzzles, but certainly not ready for a 500 piece one - which is sure to rob his interest if introduced to him at this stage. I am not sure if it is right or wrong - he doesn't solve the puzzles by looking at the picture. He does it by trial and error by trying to to fit in various pieces of the jigsaw and eventually gets it right. Very soon, we shall increase the challenge level in such a way that his interest level on this remains intact.
