Tips for Solving Hard Riddles
Start by reading the wording literally. Many difficult riddles become confusing because solvers immediately assume the question means something it never actually says.
Next, identify unusual words. Terms such as “all,” “only,” “single,” “first,” and “nothing” are often important clues.
Finally, challenge your first assumption. If an answer seems impossible, ask whether the riddle is using a different meaning of a word or presenting a situation from an unexpected perspective.
