Sports (American English) includes all forms of competitive physical activity or games which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing enjoyment to participants, and in some cases, entertainment for spectators. Hundreds of sport exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals.
In the certain sport such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a match) is between two sides, each attempting to exceed the other. Some sports allow a tie game; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many games leagues make an annual champion by arranging games in a regular games season, followed in some cases by playoffs.
