Abstract
A spherical puzzle has an internal spherical cavity having a plurality of maze sections interconnected, with an exit opening of an upper maze section spaced at an opposed end of a circuitous path of an underlying maze section. The polar ends of the maze section with the maze sections coaxially aligned relative to the North and South polar portions of the maze have transparent caps for viewing an entrance and exit of a game sphere directed through the sections.
Claims3
A spherical puzzle, wherein the puzzle comprises,
- a rigid spherical shell having a spherical cavity therewithin defined along an axis, the axis having opposed ends which intersect the shell at a North pole and a South pole,
- and
- a transparent North window medially intersected by the axis at the North pole,
- and
- a Southern semi-spherical window directed through the shell and medially intersected by the axis at the South pole,
- and
- a North window entrance directed through the North window, with a North cap concave support trough positioned below the North window, with the North concave support trough having a North support trough exit opening directed therethrough,
- and
- a plurality of maze sections coaxially aligned along the axis, with each maze section having a maze floor orthogonally oriented relative to the axis, and each maze floor having a respective exit opening, wherein a lowermost maze section below the North concave support trough includes a South cap exit opening in communication with a South cap support trough.
