Tennikoit is an outdoor racquet sport that originated in South India in the early 1960s. It is played with a rubber ring called a "tennikoit" across a doubles badminton-sized court divided by a net. The game can be played individually or with a partner. Players must score 21 points within a 30-second time limit to win each set, with the first to win two out of three sets declared the match winner. There are now over 5,000 registered Tennikoit players in India participating in national and international competitions.
