I bought these puzzles for my two little girls. They love Minnie and many other heroes and heroines but also the 4 puzzles allow for plaisie both as parts numbers are increasing. And then the second will soon do both more difficult. They have always loved puzzles and never discouraged. One can also help each other. kids who love puzzles will be happy to find in that box puzzles of different strengths and will be happy to do it. Buy it, you will not be disappointed!
