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.
Cricket is a bat-and-ball game played on a cricket field (see image, right) between two teams of eleven players each. The field is usually circular or oval in shape and the edge of the playing area is marked by a boundary, which may be a fence, part of the stands, a rope, a painted line or a combination of these; the boundary must if possible be marked along its entire length.

During the 1980s, India developed a more attack-minded batting line-up with stroke makers such as the wristy Mohammed Azharuddin, Dilip Vengsarkar and all-rounders Kapil Dev and Ravi Shastri. India won the Cricket World Cup in 1983, defeating the favourites and the two-time defending champions West Indies in the final at Lords, owing to a strong bowling performance. In spite of this, the team performed poorly in the Test arena, including 28 consecutive Test matches without a victory. In 1984, India won the Asia Cup and in 1985, won the World Championship of Cricket in Australia. Apart from this, India remained a weak team outside the Indian subcontinent. India's Test series victory in 1986 against England remained the last Test series win by India outside the subcontinent for the next 19 years. The 1980s saw Gavaskar and Kapil Dev (India's best all-rounder to date) at the pinnacle of their careers. Gavaskar made a Test record 34 centuries as he became the first man to reach the 10,000 run mark. Kapil Dev later became the highest wicket-taker in Test cricket with 434 wickets. The period was also marked by an unstable leadership, with Gavaskar and Kapil exchanging the captaincy several times.
Subject to certain variations, on-field clothing generally includes a collared shirt with short or long sleeves; long trousers; woolen pullover (if needed); cricket cap (for fielding) or a safety helmet; and spiked shoes or boots to increase traction. The kit is traditionally all white and this remains the case in Test and first-class cricket but, in limited overs cricket, team colours are worn instead.
The Bombay Gymkhana hosted the first ever Test match in India which is the only Test it has hosted to date. Wankhede Stadium, established in 1974, has a capacity to hold 33,000 spectators and is currently the most popular venue in the city. It has hosted 24 Test matches. It was the unofficial successor of the Brabourne Stadium, which is also located in Mumbai. Mumbai is often considered the cricketing capital of India because of its fans and the talent it produces (see Mumbai cricket team) and thus the stadium regularly hosts major Test matches. The M. A. Chidambaram Stadium in Chepauk is also considered to be an important historical Indian cricket ground, established in the early 1900s it was the site of India's first Test victory.
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. 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.
