Abstract: A toy construction element is disclosed having a body with at least one projection extending therefrom and a plurality of complementary-shaped recesses formed therein. The recesses extend along at least two different axes and are configured for receiving a corresponding projection from like elements so as to allow like construction elements to be interconnected in three dimensions. The projections and/or recesses may be formed with snap-fit interlocking features whereby the element is configured for interlocking engagement with like elements. The snap-fit interlocking features can include complementary locking formations formed on each projection and each recess. The formations are configured to pass over each other as the projection of one element is received in the recess of another element when like elements are assembled, and the recess is at least in part defined by a resilient component that flexes to resist passage of the formations during assembly and disassembly.

Abstract: A three-dimensional logic puzzle is provided. The puzzle includes a plurality of identically shaped puzzle components of an irregular form. Each puzzle component is configured to engage with another identically shaped puzzle component via projections and recesses formed on the sides of the puzzle components. The plurality of puzzle components are interengagably assembled into the form of a predetermined three-dimensional geometric shape.
