Abstract
A game of manual dexterity having a hand manipulatable housing with a wall that presents a curved playing surface, an operating member having a magnetic portion and a weighted portion, and an object member separate from the housing, made of a ferromagnetic material and having a curved playing surface. The operating member is mounted within the housing so that the weighted portion maintains the magnetic portion in a position near the uppermost inner surface of the housing wall when the housing is turned. The object member is attracted to the magnetic portion of the operating member so that when the playing surfaces of the object member and housing are engaged, the object member is maintained in tracking engagement with the housing when it is turned.
