Sports encompass various physical activities and games, often competitive and organized, aimed at utilizing, maintaining, or enhancing physical abilities and skills. They offer enjoyment to participants and entertainment to spectators. Sports can involve varying numbers of participants, from individual pursuits to activities with hundreds of people. Competition formats include teams, individuals, or a combination of both. While some sports permit ties, others employ tie-breaking methods to determine a single winner. Tournaments and leagues with regular seasons and playoffs are common ways to organize competitions and crown champions.
