Sport encompasses a wide range of physical activities and games, often competitive and organized, that aim to utilize, maintain, or improve physical abilities and skills. Sports are enjoyed by participants and can be a source of entertainment for spectators. The number of participants can vary greatly from individual to team-based activities. While some sports allow for ties, others implement tie-breaking methods to determine a winner. Tournaments and leagues, which culminate in a champion, are common structures in sports.
