Riddles are puzzles or questions that require creative thinking to solve. They often present a mystery or a play on words, challenging the solver to think outside the box. Riddles can be found in various cultures and are used for entertainment, education, and even as a form of storytelling. Mysteries, on the other hand, refer to situations or events that are difficult to understand or explain. They often involve unknown elements, such as detective stories or unsolved crimes, and engage the audience's curiosity. Both riddles and mysteries stimulate critical thinking and problem-solving skills.
