You may have seen a jigsaw puzzle, a crossword puzzle, or a Sudoku at some point in your life, but those barely crack the cover on the whole anthology that is "puzzling"! Puzzleday puzzles also have a tendency to get... creative, so you might see something that looks especially strange! Check out a few sample puzzles or peruse our collection of puzzles from past events.
