This is another of three puzzles we bought for our grandson who is 10 years old. He was too old to be interested in starter, 10 or 12 piece puzzles anymore, but certainly not ready to tackle something like a 500 or 1000 piece adult puzzle. These 180 piece puzzles were just perfect for his age and development. It kept him interested and working away until he finished the whole thing. And what kid doesn't find dinosaurs interesting? It was reasonable in price, fit together perfectly and sturdy enough to use many times over. Perfect picture for kids.
