Most of us (in the northern hemisphere, anyway) can start to feel a bit stir-crazy around this time of year. Luckily today, January 29, is National Puzzle Day! Ok, maybe puzzles won’t completely cure the winter blues, but it’s worth a shot! Whether you prefer crossword, logic, jigsaw, linguistic or mathematical puzzles is up to you.

John Spilsbury invented the first jigsaw puzzle (pictured above) in 1766. Originally meant as a teaching tool for geography classes, the jigsaw puzzle caught on. And for good reason too—puzzles teach important motor and problem solving skills, and aid in creative and abstract thinking. By the 19th century, chromolithography made it easy to create an array of colorful designs that were applied or printed directly onto puzzle boards, blocks and boxes. Even in the video game era, puzzles of all kinds continue to delight us. Perhaps the thrill of completion is what keeps this pastime so popular.
