A toy construction kit, particularly a three-dimensional puzzle, including a plurality of generally regular polygonal construction elements that can be releasably assembled, through tab-and-slot, hinged interengagement, to form a toy construction. Each of the construction elements is formed from a resiliently flexible sheet of plastics material, for example, polypropylene. A single toy construction may include construction elements in regular polygonal shapes of triangles, squares, and pentagons with all of the sides of the elements having, the same length. The tab-receiving slots of the tab-and-slot engagement may be provided in flanges formed integrally with and projecting from the sides of the construction elements. Advantageously, a plastics hinge joining the tab to the side of one of the elements may be set back from the side of the element and joined thereto by short cut portions, the slot formed in the flange on the other element may be stood out from the side of the other element by a similar distance, and the ends of the slots may be arcuate to join the slot to the hinge. In the toy construction, the tab and flange will overlap their respective opposing elements on the same side of the joint.
