And you thought your trusty Puzz 3-D was hard… this one is in a category of its own. Designer Clemens Habicht created what is likely the most impossible puzzle ever to grace a dining room table. Each frustrating piece represents a different color, so there is a method to the madness. Follow the CMYK gradient in exact order and you’ll have no trouble completing the design. No trouble at all (that was sarcastic).

Unfortunately, the puzzle ($33) is sold out for now, but you can pre-order the second edition from Lamington Drive Editions.
