This is a tricky logic puzzle that you can solve using real-life materials, not just pencil and paper. You have 16 matchsticks that are arranged to make five complete squares. There are two rows of squares; the bottom row has three squares, and the top row has two squares, but the first square on the top row shares a matchstick with the last square on the bottom row. Now, you must move only two matchsticks, positioning them horizontally or vertically, to create only four squares. No two squares can share a side. Can you solve it?
