Abstract: Embodiments may include multiple building elements that may include connector building elements and basic building elements for the construction of three-dimensional puzzles. Connector building elements may include a connector portion that may insert into a receiving portion of a basic building element. Connector building elements and basic building elements may rotate with respect to each other to a fixed point where respective faces of the connector building element and the basic building element are aligned; the alignment may be to pre-determined angles. Connector building elements and/or basic building elements may include blocking and/or locking structures that may resist and/or arrest the rotation of the elements with respect to each other and to aid in maintaining the alignment of the elements.

Abstract: A construction kit with basic building elements (1) and connecting pieces (M) and a game with variable level of intellectual challenge in which a first player assembles the basic building elements into different composite building elements by using the connecting pieces, introduces connecting pieces into receiving means (a2) on the outer faces of the composite building elements, and assembles a final structure. A second player is presented with the challenge of disassembling the final structure and reassembling it from the same composite building elements with the same connection means in the same positions that were used by the first player.
