Three-dimensional puzzle

A method for configuring a three-dimensional puzzle comprising a plurality of puzzle blocks together forming a predetermined three-dimensional puzzle shape, wherein each puzzle block comprises either a male or a female connecting element facing all different directions of the puzzle block, the directions of the connecting elements being selected from an orthogonal coordinate system, wherein each side of each puzzle block has a surface plane and each connecting element is rotationally symmetric such that the connecting element is identical for every ninety degree rotation in the surface plane;

• wherein the connecting elements for the respective puzzle block are configured such that each puzzle block is unique, and wherein each connecting element has a shape selected from a group comprising at least three different male connecting elements and at least three corresponding different female connecting elements, wherein each female connecting element comprises a portion protruding above the surface plane such that it is not possible to arrange two puzzle block sides comprising female connecting elements in direct contact with each other, the method comprising:
• selecting a first puzzle block for a first position of a first layer;
• subsequently configuring adjacent puzzle blocks so that each puzzle block has at least one male or female connector corresponding to a connector of at least one an adjacent previous block, thereby forming a three-dimensional puzzle comprising n×m×l puzzle blocks, n, m and l being integers.
