What is 24 hours long, all about solving problems, and is one of the best unofficial holidays of the year? National Puzzle Day, of course! Each year on January 29th, National Puzzle Day recognizes an invention that gives us the chance to exercise our brains all while learning something new. While the puzzle holiday has only been around since 2002, puzzles themselves have been around in one form or another since ancient times. With so many different genres of puzzles, it’s not really all that puzzling as to why puzzles remain so popular. Join in the celebration today by pulling out a favorite jigsaw, or trying a crossword, Sudoku, or brain teaser. #NationalPuzzleDay
