Sometimes the simplest-looking things are the hardest to fathom. Well, you can take it from us, the Master of Puzzles Box fits very comfortably into this category. This deceptively difficult puzzle features thirteen different pieces (twelve pentominoes & one square) & it's up to you to fit them all together. Think of it as a slow, multidimensional game of Tetris that can be solved in a number of different ways. You'll have to combine logic, spatial awareness, & zen-like patience to conquer this one!
