Puzzles are popular in our house. Emily recently found a 3D globe puzzle I got as a kid and was determined to put it together. She worked on it for several days by herself before enlisting some help from Mom & Dad. The puzzle has numbered pieces that start from the bottom and have you work in a circle spiraling up, so you don't have to try to match up the exterior picture. It was also in chunks from the last time I put it together 20+ years ago. However, it's still really tricky trying to get things to stay in place without collapsing. Emily was very proud of the finished product!
