A constructional toy comprising a plurality of elements (10, 62, 64, 70, 80, 90, 91, 92, 93, 94, 95, 120, 130, 140, 150, 170, 180, 190, 200, 210) of at least two different types which can be assembled together to form a variety of three dimensional structures. The elements include a main element (10, 62, 64, 70, 80, 150, 190, 200, 210) comprising a first engagement feature (30) having N splines, where N is an integer not less than three; and a second engagement feature (40) having N' splines, where N'<N. |
