Abstract
Abstract A two dimensional puzzle is disclosed comprising thirty-six four sided tiles. Each of the tiles includes some means for indicating its orientation; and all but one of the tiles further comprises a part of at least one means for matching the tile to other tiles. The matching means illustratively is an interlocking connector having a male and female element one of which elements is disposed in a side of a first tile and the other of which is disposed in a side of a second tile to which the first tile is connected. Each of the four side surfaces of each tile has either a male connector element, a female connector element or neither element; and each tile has a different combination of these three features on its four sides. The puzzle is to arrange the thirty-six tiles in their correct orientation in a six-by-six rectilinear array so that the tiles interlock. Extensions of the puzzle to other dimensions are also disclosed, in particular, a three-dimensional puzzle of 216 blocks that can be assembled in a six-by-six-by-six array of interlocking blocks.

Claim 1
Independent Claim
133 words
A puzzle comprising thirty-six tiles, each tile having four sides, means for establishing a direction of each tile in a plane defined by one of its major surfaces, means for matching the tiles to one another comprising first and second matching element in some of the sides of said tiles, each side having only one first matching element, second matching element or neither matching element and each tile having a different arrangement of first matching element, second matching element and neither matching element on its four sides, whereby the thirty-six tiles can be arranged in a six-by-six array of matched tiles in which interior sides of tiles having neither first nor second matching element are placed adjacent one another and sides having first matching elements are placed adjacent sides having second matching elements.
