ABSTRACT:
A puzzle includes a plurality of elongated blocks (22-37) of square cross section. Each block has a first end (22a-37a) rabbeted along one of the diagonals of the square cross section to form two turning treads separated by a riser and a second end (22b-37b) opposite the first end rabbeted to form two straight treads separated by a riser. A base container (38) having a bottom (40) and walls (42) extending therefrom receives the blocks therein with either the first or second end of each block engaging the bottom of the base container. The opposite end of each block is positioned upwardly to form a desired configuration of the blocks extending from the base container.
