Patent ID: 6883802

Claim:
A puzzle comprising: a plurality of elements arranged to define at least one row of elements and at least one column of elements, each of the plurality of elements being rotatable about a first axis and a second axis, the first axis of each of the plurality of elements being parallel to the first axis of every other of the plurality of elements, the second axis of each of the plurality of elements being parallel to the second axis of every other of the plurality of elements, each of the elements including first and second arrays of co-planar holes located on the outer surface of the sphere, the first array of co-planar holes being orthogonal to the second array of co-planar holes, the co-planar holes of each of the first and second arrays of co-planar holes comprising center holes located at an intersection of the first and second arrays of co-planar holes and field holes located along only one of the first and second arrays of co-planar holes; a case that restrains non-rotational movement of each of the plurality of elements; and a linkage structure that forces all elements in the at least one row of elements to rotate about their respective first axes when any one of the plurality of elements in the at least one row of elements is rotated about its first axis and that forces all elements in the at least one column of elements to rotate about their respective second axes when any one of the plurality of elements in the at least one column of elements is rotated about its second axis.
