2 1/2 year old grandson actually gasped when he opened the box. His favourite puzzle and he just can't get enough, working it daily and telling stories as he works and completes the puzzle. From the first attempt he was able to complete the puzzle without help as the pieces are large enough to suggest placement. The colours are bright, the pieces are large enough for small hands and the pieces just feel good. This puzzle occupies him for 60-90 minutes, incredible for a 2 1/2 year old.
