SECTION I - CLASS DEFINITION

This class includes:

Apparatus or means, such as games and sports, by which contests of skill or chance may be engaged in among two or more participants, where the result of such contests can be indicated according to definite rules;

Apparatus or means, such as puzzles and fortune telling devices, by which a test of the skill or fortune of one or more persons, in accomplishing some sought result, may be obtained, chance devices being included, even if not of themselves games or elements of games, by reason of their similarity to other chance devices herein;

Targets combined with devices for projecting aerial or surface projectiles or missiles against or through the targets, per se, and projectors, per se, only if the projectile passes at all times over a surface;

Devices ancillary and appurtenant to games for which there is no provision in other classes.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

This class is subordinate to both Class 473, Games Using Tangible Projectile, and Class 463: Amusement Devices: Games-- wherein Class 473 is specific under Class 463, and wherein Classes 273, 463, and 473 are further specific under Class 472, Amusement Devices.

Classes 463 and 473 are intended to eventually replace Class 273 through a series of stages. When all of the subject matter of Class 273 has been reclassified and incorporated within these classes (463 and 473), Class 273 will be abolished. Until Class 273 is abolished, it is to be considered subordinate to Classes 463 and 473. Stated otherwise: the subclasses of Class 273, along with their hierarchical arrangement, are to be considered as following after the subclasses of, appropriately, Class 463 or 473 (i.e., the first occurring subclass of Class 273 follows the last occurring subclass of appropriate Class 463 or 473).
