Kho Kho is a famous tag team game that was established in "1914" in Maharashtra, India. It is played by two teams of twelve nominated players from a total of fifteen, with nine entering the field on their knees (Chasing Team) and three extra (Defending Team) attempting to escape being touched by members of the other team. The game lasts for about ten minutes and it is based on physical strength rather than skill. It can be played as a match or as a series. Kho Kho means nine holes in Marathi language. This ancient game must have been popular long before 1914 when it was first documented in literature. There are reports of this game being played as early as 17th century but these reports are not verified. Kho Kho probably originated in India but later on it was also played in Pakistan and Iran. Today it is popular in rural Maharashtra where it can be seen during annual fairs or festivals. The chasing team attempts to catch the defending team's players by touching them on the back of the head with a bamboo stick while the remaining players try to prevent this by hitting the chasers with their own sticks. The one who stays alive after ten minutes wins the game. Kho Kho is an interesting example of a competitive game that does not use balls nor nets. Instead each player has a number which is added up at the end of the game to determine the winner.
