Playing surface for spinning top toy apparatus and methods

A toy stadium apparatus for battling tops, comprising:

• a first tier battling arena having a concave bowl-shaped surface having a central area and first, second, third and fourth quadrant areas along the periphery of the central area, said quadrant areas each being adjacent the central area and inclined therefrom;
• a first arc segment banked surface at the first quadrant area with a corner defined by a first inclined battling surface curved region having an extent determined by the length of a first radius from a first specified point in the central area of the concave bowl-shaped surface;
• a second arc segment banked surface at the second quadrant area with a corner defined by a second inclined battling surface curved region having an extent determined by the length of a second radius from a second specified point in the central area of the concave bowl-shaped surface;
• a third arc segment banked surface at the third quadrant area with a corner defined by a third inclined battling surface curved region having an extent determined by the length of a third radius from a third specified point in the central area of the concave bowl-shaped surface;
• a fourth arc segment banked surface at the fourth quadrant area with a corner defined by a fourth inclined battling surface curved region having an extent determined by the length of a fourth radius from a fourth specified point in the central area of the concave bowl-shaped surface;
• and
• said first, second, third and fourth specified points in the central area from which each respective first, second, third and fourth radii emanates together delineate the four corner points of an irregular quadrilateral connecting said first, second, third and fourth specified points, wherein each of the first, second, third and fourth arc segment banked surfaces define an asymmetrical battling surface.

A method for manufacturing an asymmetrical battling stadium, comprising the steps of:

• providing a first tier having a concave bowl-shaped surface with a central area and first, second, third, and fourth quadrant areas along the periphery of the central area, each of the quadrant areas being adjacent the central area and inclined therefrom;
• positioning a first arc segment banked surfaces at the first quadrant area with a corner defined by a first inclined battling surface curved region having an extent determined by the length of a first radius from a specified point in the central area of the concave bowl-shaped surface;
• positioning a second arc segment banked surface at the second quadrant area with a corner defined by a second inclined battling surface curved region having an extent determined by the length of a second radius from a second specified point in the central area of the concave bowl-shaped surface;
• positioning a third arc segment banked surface at the third quadrant area with a corner defined by a third inclined battling surface curved region having an extent determined by the length of a third radius from a third specified point in the central area of the concave bowl-shaped surface;
• positioning a fourth arc segment banked surface at the fourth quadrant area with a corner defined by a fourth inclined battling surface curved region having an extent determined by the length of a fourth radius from a fourth specified point in the central area of the concave bowl-shaped surface;
• and
• connecting said first, second, third and fourth specified points in the central area from which each respective first, second, third and fourth radii emanates, delineating the four corner points of an irregular quadrilateral wherein each of the first, second, third and fourth arc segment banked surfaces are defining an asymmetrical battling surface.
