This mind-teasing Square Root puzzle stands out from the crowd for two reasons: first, it's difficult, requiring more than 80 moves to solve; second, it's big (7.5-inches-by-9-inches) and handsome, handcrafted from smooth, unpainted wood, backed with wine-colored felt. The object of the game is to maneuver the largest square out through the slot at the bottom--without removing, lifting, or turning any of the 10 pieces. Did I mention how difficult it is? Luckily, a Cheater's Map to Success is available separately from Square Root Games at an additional charge. --Rebecca Hughes
