It gets extremely hard. I even wonder if some of the levels are impossable. There are no hints either. The puzzles would have only like 50 peices, yet they were harder than traditional jigsaw puzzles that have several hundred peices. You inlay them, but the catch is you have to figure out mathamatically where they go. Unlike jigsaw where you know that you've placed a peice in the right place right when you put it in. If your really good at figuring things out many moves in advance than give this a try, but if your weak in that area, then you might get very frustrated.
