Kabaddi has apparently become the second most watch sport in India. According to Wikipedia,
Kabaddi is a contact team sport. Played between two teams of seven players, the object of the game is for a single player on offence, referred to as a “raider”, to run into the opposing team’s half of a court, tag out as many of their defenders as possible, and return to their own half of the court, all without being tackled by the defenders, and in a single breath. Points are scored for each player tagged by the raider, while the opposing team earns a point for stopping the raider. Players are taken out of the game if they are tagged or tackled, but can be “revived” for each point scored by their team from a tag or tackle.
Rugby meets tag minus the ball.
Some of the matches uploaded to YouTube are fascinating, like this one.
