Child play puzzle

A child play puzzle set comprising:

• a base;
• a first play module supported on the base, the first play module comprising:
• a first set of pieces each defining a non-circular aperture therethrough, and
• a first pole extending from the base along a first pole axis, the first pole configured to sequentially receive each piece of the first set of pieces with the first pole extending through the aperture of each piece to form a stack of the pieces along the first pole, the first pole comprising a plurality of sections spaced along its length, each section being of non-circular cross-section in a plane perpendicular to the first pole axis,
• wherein at least one of the sections is rotatable about the first pole axis with respect to an adjacent one of the sections that is rotationally fixed with respect to the base, such that moving a piece from about the rotatable section to about the adjacent section requires rotationally aligning the rotatable section with the adjacent section;
• a second play module supported on the base and spaced from the first play module, the second play module comprising:
• a second set of pieces each defining a non-circular aperture therethrough, and
• a second pole extending from the base along a second pole axis, the second pole configured to sequentially receive each piece of the second set of pieces with the second pole extending through the aperture of each piece to form a stack of the pieces along the second pole, the second pole comprising a second plurality of sections spaced along its length, each section being of non-circular cross-section in a plane perpendicular to the pole axis,
• wherein a first section of the second plurality of sections is rotationally misaligned with a second section of the second plurality of sections and spaced from the second section to define a gap therebetween, such that moving a piece from about the first section to about the second section requires rotationally aligning, at the gap, the piece with the second section;
• and
• a third play module supported on the base and spaced from the first play module, the third play module comprising:
• a third set of pieces each defining a threaded aperture therethrough;
• and
• a third pole extending from the base along a third pole axis, the third pole comprising an exterior thread and configured to threadedly receive each piece of the third set of pieces with the third pole extending through the aperture of each piece to form a stack of the pieces along the third pole.
