Mini Jack Puzzle
The Mini Jack Puzzle is just like the Jack Puzzle, only smaller. With this decreased stature comes an increased challenge—the manual dexterity required to conquer the Mini Jack borders on masochism. This one is not for the weak-willed. This six-piece puzzle is portable, beautiful, and maddeningly difficult. If you thrive on frustration and have the hands of a skilled surgeon, the Mini Jack Puzzle is the one for you.
