Stacking piece puzzle

A puzzle comprising:

• a base member having an upstanding substantially vertical center post;
• a plurality of game pieces, each of said game pieces having a center aperture dimensioned to receive said center post therethrough so that said game pieces are stackable atop one another over said base member and around said center post;
• each of said game pieces having an aperture formed obliquely therethrough, said apertures being located in said game pieces so as to be aligned with one another only when said game pieces are stacked in a unique order and wherein each of said game pieces is positioned to a unique rotational position around said center post relative to the remaining ones of said game pieces;
• and
• an elongate, substantially straight rigid game rod insertable into said aligned apertures of said game pieces;
• the object of said puzzle being to stack said game pieces in said unique order on said base and to position said game pieces in said unique rotational positions around said center post so as to align said apertures and allow thereby the passage of said game rod therethrough.

A puzzle comprising:

• a base;
• a substantially vertical center dowel projecting upwardly from said base;
• a plurality of game pieces, each having a center aperture dimensioned to receive said center dowel therethrough, stacked atop one another and around said center dowel to form a substantially solid stack atop said base around said center dowel;
• a plurality of elongate rigid game dowels;
• and
• a plurality of apertures formed obliquely through said stacked game pieces dimensioned to receive therein said game dowels;
• said apertures being located and arranged so that each of said game dowels is oriented at a unique oblique angle relative to a horizontal plane when it received in a respective one of said apertures and so that each of said game dowels is located at a unique distance from said center dowel when it is received in a respective one of said apertures.

A puzzle comprising:

• a base;
• a center post projecting upwardly from said base;
• and
• a plurality of game pieces, each of said game pieces including a center aperture dimensioned to receive said center post therethrough and each of said game pieces further including a pair of opposed, nonparallel, substantially planar upper and lower surfaces;
• said nonparallel upper and lower surfaces being oriented so that said game pieces can be stacked atop one another over said base and around said center post to form a substantially solid structure only when said game pieces are stacked in a unique order and are positioned to a unique orientation relative to one another.
