A puzzle preferably including a case and a plurality of elements contained therein, each having at least one recess (preferably six) formed thereon. Each of the elements is secured in a fixed position relative to the case and rotatable about at least two, and preferably three, perpendicular axes of rotation. Each of the plurality of elements has a starting position from which the element can be rotated about any one of the axes of rotation. Rotation of each element is limited to one of the axes of rotation when the element is not in the starting position. At least one insert (preferably one less in number than the total number of recesses in the elements) is provided. Each insert includes first and second opposing surfaces that are adapted to be received in any one of the recesses.
