Abstract
A puzzle game or toy is disclosed comprising two spherical shells made of hard plastic or metal material and having over their surface a multiplicity of circular holes cut therein in a random pattern, the holes being of equal diameter with the exception of one hole having a slightly larger diameter. The second spherical shell has an inner diameter slightly larger than the diameter of the first spherical shell and mounted over the first shell such that the two shells are freely rotatable relative to each other. A spherical ball of metal or plastic is positioned inside the two spherical shells and is of a diameter such that it will pass through the two large holes but none of the other holes.
Claims4
A puzzle game or toy comprising:
- (a) a first spherical shell of a size that can be readily manipulated by hand and made of hard plastic or metal material, and having over its surface a multiplicity of circular holes cut or formed therein in a random pattern said holes all being of equal diameter with the exception of one hole having a slightly larger diameter.
- (b) a second spherical shell similar to the first but having an inner diameter slightly larger than the outer diameter of the first spherical shell and mounted over the first shell such that the two shells are freely rotatable relative to each other, said second spherical shell having an identical pattern of holes formed in its surface such that at only one relative position of the two shells, the two patterns of holes are completely in line with the one large hole in the outer shell overlying the one large hole in the inner shell, and
- (c) a spherical ball of metal or plastic positioned inside the two spherical shells and of a diameter such that it will pass through the two large holes but none of the other holes.
