The ball is a hard leather-seamed spheroid, with a circumference of 22.9 centimetres (9.0 in). The ball has a "seam": six rows of stitches attaching the leather shell of the ball to the string and cork interior. The seam on a new ball is prominent and helps the bowler propel it in a less predictable manner. During matches, the quality of the ball deteriorates to a point where it is no longer usable; during the course of this deterioration, its behaviour in flight will change and can influence the outcome of the match. Players will, therefore, attempt to modify the ball's behaviour by modifying its physical properties. Polishing the ball and wetting it with sweat or saliva is legal, even when the polishing is deliberately done on one side only to increase the ball's swing through the air, but the acts of rubbing other substances into the ball, scratching the surface or picking at the seam are illegal ball tampering.[71]
Although cricket was introduced to India by European merchant sailors in the 18th century, and the first cricket club was established in Calcutta (currently known as Kolkata) in 1792, India's national cricket team did not play its first Test match until 25 June 1932 at Lord's, becoming the sixth team to be granted Test cricket status. In its first fifty years of international cricket, India was one of the weaker teams, winning only 35 of the first 196 Test matches it played. From 1932 India had to wait until 1952, almost 20 years for its first Test victory. The team, however, gained strength in the 1970s with the emergence of players such as batsmen Sunil Gavaskar and Gundappa Viswanath, all-rounder Kapil Dev and the Indian spin quartet of Erapalli Prasanna, Srinivas Venkataraghavan, Bhagwat Chandrasekhar and Bishen Singh Bedi.
The domestic competitions include the Ranji Trophy, the Duleep Trophy, the Vijay Hazare Trophy, the Deodhar Trophy, the Irani Trophy and the NKP Salve Challenger Trophy. In addition, the BCCI conducts the Indian Premier League, a Twenty20 competition, which is also one of the biggest sports leagues in the world and the biggest cricket league in the world. The Indian cricket team is also accredited with the honour of winning all the ICC tournaments under M.S. Dhoni's captaincy, which is a world record. While cricket is by far the most popular sport in the country it is not the country's national sport since India has no national sport.[6]
The main objective of each team is to score more runs than their opponents but, in some forms of cricket, it is also necessary to dismiss all of the opposition batsmen in their final innings in order to win the match, which would otherwise be drawn.[66] If the team batting last is all out having scored fewer runs than their opponents, they are said to have "lost by n runs" (where n is the difference between the aggregate number of runs scored by the teams). If the team that bats last scores enough runs to win, it is said to have "won by n wickets", where n is the number of wickets left to fall. For example, a team that passes its opponents' total having lost six wickets (i.e., six of their batsmen have been dismissed) have won the match "by four wickets".[66]

Cricket is one of many games in the "club ball" sphere that basically involve hitting a ball with a hand-held implement; others include baseball, golf, hockey, tennis, squash, badminton and table tennis.[2] In cricket's case, a key difference is the existence of a solid target structure, the wicket (originally, it is thought, a "wicket gate" through which sheep were herded), that the batsman must defend.[3] The cricket historian Harry Altham identified three "groups" of "club ball" games: the "hockey group", in which the ball is driven to and fro between two targets (the goals); the "golf group", in which the ball is driven towards an undefended target (the hole); and the "cricket group", in which "the ball is aimed at a mark (the wicket) and driven away from it".[4]
The International Cricket Council (ICC), which has its headquarters in Dubai, is the global governing body of cricket. It was founded as the Imperial Cricket Conference in 1909 by representatives from England, Australia and South Africa, renamed the International Cricket Conference in 1965 and took up its current name in 1989.[112] The ICC in 2017 has 105 member nations, twelve of which hold full membership and can play Test cricket.[114] The ICC is responsible for the organisation and governance of cricket's major international tournaments, notably the men's and women's versions of the Cricket World Cup. It also appoints the umpires and referees that officiate at all sanctioned Test matches, Limited Overs Internationals and Twenty20 Internationals.
Eden Gardens in Kolkata has hosted the most Tests, and also has the second-largest seating capacity of any cricket stadium in the world, being capable of holding more than 66,000 spectators. Founded in 1864, it is one of the most historical stadiums in India, having hosted numerous historical and controversial matches.[67] Other major stadiums in India include the Feroz Shah Kotla Ground, which was established in 1883 and hosted memorable matches including Anil Kumble's ten wickets in an innings haul against Pakistan. For the last two years, the ground has been undergoing renovation.[68]
