A ball is a round object that is used most often in sports and games. Balls are usually hollow and spherical but can be other shapes, such as ovoid (only in a few special cases) or solid (as in billiards) and flat (as in ice hockey). In most games using balls, the play of the game follows the state of the ball as it is hit, kicked, or thrown by players.
Balls were used in ancient times by the early Egyptians, the ancient Greeks and Romans, and the Aztecs and earlier Mesoamerican peoples.
