Remember the Disney movie 101 Dalmatians? They're back, with progeny, sitting here patiently waiting for you to put this puzzle together. So what makes this jigsaw puzzle so hard? First of all, the image on the front--dozens of adorable dalmatians--is identical to the image on the back, except that it's been rotated 90 degrees. Second, while most jigsaw puzzles are cut from one side only, making it fairly easy to determine which side is the top, this killer puzzle is cut from both sides (vertically on one, and horizontally on the other). Be sure to let your family know where you'll be, so they can bring you food every once in a while. The world's most difficult puzzle has 529 pieces and measures 15 by 15 inches when completed. --Rachel Radway
