Patent ID: 7644924

Claim:
A three-dimensional puzzle bearing a shape of a cube, the puzzle comprising: cubiform elements of substantially uniform size, the cubiform elements joined together so that outer faces of the cubiform elements comprise respective surfaces of the cube; mutually perpendicular axes intersecting at a centroid of the cube and passing orthogonally through a center point of each face of the cube; integrally formed cam elements configured to retain horizontal rows of cubiform elements into engagement with one another, yet allow relative movement of one of a selected row with respect to its adjacent row, integrally formed cam elements configured to retain vertical columns of cubiform elements into engagement with one another, yet allow relative movement of one selected column with respect to an adjacent column; wherein, the integrally formed cam elements allow relative rotation of a selected one of a row or column, the relative rotation being about one of the axes at one selected time; an indicia on each outer face the indicia consisting of single digit natural numbers; a first surface that is horizontal and facing downward; a first group of three rows, each row having nine consecutive elements that traverse three contiguous surfaces of the puzzle; and, an orientation parallel to the first surface, and and each row also having a beginning coinciding with a first edge orthogonal the first surface, and, one of each indicia without duplicate when the puzzle is in a solved condition wherein, when the puzzle in the solved condition, at least one surface bears each indicia with no duplicate indicia.
