Deviously Difficult Mind Bending Puzzles
Play supergames for the super-smart. These mind-blowing, brain-bending puzzles use a deviously tricky mix of geometry and combinatronics (the different ways objects can be arranged), and emphasize structure, pattern, and color. Everything’s visual and as enticing to the eye as to the wits. Try to solve the Impossible Domino Bridge Problem: at first glance, the top-heavy structure looks as if it would just tumble. But give it some thought and you’ll realize that not only can it be built but that you can build it yourself. Take the Ingenious Tangram Challenge; put together a Stars Puzzle; and Draw, Halve, and Quarter all the rooms in a house into equal-size spaces. There’s illuminating background information on the puzzles’ origins, too.

Fiendishly Frustrating Brain Twisting Puzzles
Jumping Coins, Cubes and Routes, Find the Polygons, and Distortrix: these are just a few of the incredible brain-twisting conundrums in this colorful, super-fun compilation by puzzle whiz Ivan Moscovich. Sample games give a hint of what’s to come and prime your mind for the challenges you’ll face. Inside a hexagon, a continuous path connects 19 different nodes: find that trail, navigating a series of pointing arrows and visiting each node only once. On the Rebound features tricky little problems involving a pool ball on a table and the best way to shoot it. A Piece of Cake is no piece of cake: arrange the segments so that no two colored or numbered ones touch another of the same color or number. You’ll think your brain really is twisted once you solve all of these.
