This is a cute game for kids and adults. I have a younger sister who loves puzzles and card games with complex mechanics, and she also likes riddles and contests. When I come home to my father, she often asks me to play with her. All her games are very expensive and cool, but they bother her. One day I brought her a Steel Puzzle for Adults. She's been trying to figure it out all evening. She didn't manage to do it quickly, so I left her this toy. I think she appreciated such a gift. I don't like to give children silly things like teddy bears or Barbie dolls. It's better to let her solve the puzzle for a long time. It develops brains and ingenuity.
