1. A ball for a ball game comprising:
- a bladder of an air-impermeable elastic material and having a hollow spherical shape;
a flexible, generally spherical skeletal frame separate from and surrounding the bladder, maintaining bladder shape, and including a plurality of openings; and
a plurality of skin panels constituting a surface of the ball, each skin panel including at least one edge and having a shape geometrically similar to at least one opening of the frame, the edges of the skin panels being adhered to the frame with an edge of each skin panel in contact with an edge of another skin panel on the frame.
