Games and toys

A game or toy comprising a plurality of rectangular elements each having a substantially square upper face and a substantially square lower face interconnected by four rectangular side faces, the upper face having an alphanumeric character thereon, two adjacent side faces having projecting connecting means formed thereon, and the other two adjacent side faces having recessed connecting means shaped to receive and retain the projecting connecting means of another such element for joining the elements together side face to side face in two mutually perpendicular directions to form a crossword or a number game, in dependence upon whether said alphanumeric characters are letters or numbers, said connecting means being adapted for tight frictional engagement such that large assemblies of joined-together elements can be picked up and moved without said elements becoming disengaged, said each connecting means extends along said side face substantially perpendicular to the upper and lower faces of the element and extends along a middle of said side face, auxiliary connecting elements cooperate with said recessed connecting means of the rectangular elements so as to connect together two rectangular elements with their upper faces at right angles to each other, each said auxiliary connecting element includes first and second elongate members each having a cross sectional shape substantially identical to that of the projecting connecting means of the rectangular elements, and said members each having a flat side and being integrally joined together at right angles to each other and at respective midpoints of their respective flat sides.
