Abstract
Abstract Skill game comprising a base and a ball. Base has a recess which accepts the ball, the diameter of the recess being larger than the ball to prevent binding and close to the same diameter to permit manual grasp on the ball only to the extent the ball extends from the recess. The recess has a depth greater than the ball radius and less than the ball diameter and is of such depth to permit a sufficient amount of the ball to extend above the base to permit manual removal with difficulty of the ball from the recess. Plurality of recesses of different depths may be located in a single base or separate similar bases.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
235 words
A skill game comprising: a spherical ball having a substantially smooth, hard, nonporous surface; a base, said base being composed of hard material and having an exposed planar top surface; a plurality of recesses extending into said base from said top surface, the intersections of said recesses and said top surface lying in the plane of said top surface, said recesses each being circular in said plane and being of larger diameter than said spherical ball to accept said ball therein without binding and said recesses each being of sufficiently small diameter in said plane to prevent manual access to said ball below said plane, said recesses each forming a continuous surface within said base, said recesses each having a depth greater than the radius of said ball and less than the diameter of said ball so that, when said ball is in said recess, said ball extenDs less than a ball radius out of said recess, but extends sufficiently far out of said recess to permit manual removal of said ball out of said recess, each of said recesses having a depth differing from that of each of the others, the smallest depth recess having a ratio of recess depth to ball diameter of about 0.385/0.750, the largest depth recess having a ratio of recess depth to ball diameter of about 0.490/0.750, whereby manual removal of the ball differs in difficulty with each recess.

Claim 3
Dependent Claim
56 words
The skill game of claim 1 wherein: said base consists of a plurality of separable base portions corresponding in number to said plurality of recesses, and said recesses are respectively formed in said base portions, whereby said base portions are movable with respect to each other for both random and selected positioning relative to each other.
