The most gorgeously difficult puzzle you'll ever attempt to construct.
Your task is to guide a metal ball through seven layers of mazes: mazes that you can't actually see the ball rolling through. There are five different versions of these patience-testing cubes: Easy, Mean, Awful, Vicious, and Mortal. You may be cocky enough to think you could beat the Vicious version, but it would *probably* be best to start with Easy and work your way up.
Upload a photo or drawing and have it turned into an intricate puzzle made using a laser cutter. You also get to choose the shape (circle, square, or octagon) and add in several special "whimsie" pieces (like the leaves or the astronauts you see in the puzzles above).
Like Tinker Toys, these puzzles are made up of an array of seeds and rods. *Unlike* Tinker Toys, you may get a wee bit frustrated as you try to figure out how to put them together. It's all worth it.

These Lock Nesters are more challenging than they look: keep one on your desk and fiddle around with it during boring phone calls.

Have a hard time solving a Rubix cube? You're apt to have a *really* hard time solving the Dreidel. Like the Rubix, there are 26 little blocks to spin around and organize, but each of those little blocks has many other spin-able pieces attached. Good luck!
After successfully completing the puzzle, feel free to stack up the faces in a strange (and amazing) totem-pole-style tower.
A knotty puzzle that will test your spatial awareness skills as you slide around the little plastic pieces in an attempt to group them by color *without* tangling up the cords inside the case.
