Abstract: An expandable table assembly having a table top, a base, a plurality of legs supporting the base, and a plurality of releasably attachable expansion members that can be used to expand the table surface beyond the surface area of the unexpanded table top. The table top is repositionable from a first use position to a second use position by lifting the table top above the base, rotating the table top 90 degrees relative to the base in a substantially horizontal plane, and then lowering the table top back onto the base. The expansion members are attachable to the base only when the table top is in the second use position and, when attached, become part of the total surface area of the table.

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.
