ABSTRACT:
A hollow body encloses a spherical weight which rolls around the inner surface of the body as the body itself is rotated over a playing field. The inner surface of the body has magnetic inserts and the spherical weight is fitted with internal magnets having pole pieces which are flush with the surface of the weight. As the hollow body is rolled, the magnetic elements occasionally come into contact with one another to momentarily secure the weight to the inner surface and thereby alter the rolling characteristics of the body.
