Crime and mystery is an extremely popular genre — and for good reason! Aside from their fast pace and interesting characters, what people love most is trying to solve the puzzle. Take Sherlock Holmes stories, for instance. In every adaptation of the detective, the audience is trying to use the clues to guess the ending. And when they get it right, it’s beyond satisfying. It’s like we have an inner Sherlock Holmes who can determine answers from tiny details, and this spirit arises with brain teasers as well. The goal is the same: Can you guess the true answer?
Each of these puzzles is followed immediately by the answer, so don’t scroll until you are ready to check your guess. How many could you get right?
