I bought this puzzle to my granddaughter who is 4 years. She is doing more than well, since it has just passed the 60 to 100 pieces. These puzzles are XXL extra for children like her ... it takes 100 parts to him to continue to evolve, but the 100 classic rooms are too small and too difficult to handle for her little fingers. .The Puzzles like thereof, ie XXL have large parts, and especially thick parts which do not bend during assembly. I recommend these puzzles eyes closed!
