Abstract: A toy block is provided having an integrally formed, recessed surface disposed in a portion thereof which defines an open inclined passageway between sides of the block element. Game apparatus may be formed from a plurality of such block elements. The individual block elements may be arranged in various adjacent and spaced apart vertical and horizontal orientations by the players in turn during the initial course of play. After a predetermined number of such block elements have been so arranged, the players may again in turn reorient block elements in attempts to define the longest possible extended path formed by the surfaces and passageways of such block elements and the vertical spaces therebetween.
