Puzzles are a great way to exercise your brain, making it strong enough to support a calculus textbook on top of your head, or y'know, read that textbook. They are also fun enough that your friends and family won't even realize they are working their brain while they are completing them. And that makes them the perfect Christmas gift. This gift will keep the recipients busy, make them happy and (secretly) smarter:

• $12 for a cube quest puzzle (a $30 value)
• $18 for a set of 3 wooden puzzles (a $48 value)
• $20 for a set of 6 wooden puzzles (a $60 value)
• $20 for a wine bottle puzzle (a $60 value)

All serious puzzle-solvers have probably discovered at some point that the typical two-dimensional puzzle format becomes quite limited after a while. This set of wooden-block puzzles brings the brain-teasers up a new level with their three-dimensional design, adding a more challenging element to play with. Spend hours carefully assembling each unique puzzle to create something as visually pleasing as it is perplexing. With the cube quest, you must complete a seemingly simple task of filling a box with oddly shaped pieces so that they all fit inside with no spaces. The three games puzzle set comes with puzzles like the snake cube, which unravels in a chain of blocks before being reconstructed, while the six games puzzle set includes the nine-piece ladder, which comes in four shapes but needs to be restricted in a specific configuration in order to be complete. Each puzzle comes in a sturdy and well-crafted matching wood box for artful display in the house when you're not playing. For a fun party trick, get the wine bottle puzzle and encourage guests to crack it open in order to pour themselves a drink.
