Cricket is a
bat-and-ball team sport. Many variations exist, with its most popular form played on an oval-shaped outdoor arena known as a
cricket field at the centre of which is a rectangular 22-yard (20.12 m) long
pitch that is the focus of the game. A game (or match) is contested between two teams of eleven players each. One team
bats, and will try to score as many
runs as possible while the other team
bowls and
fields, trying to
dismiss the batsmen and thus limit the runs scored by the batting team. A run is scored by the striking batsman hitting the ball with his bat, running to the opposite end of the pitch and touching the crease there without being dismissed. The teams switch between batting and fielding at the end of an
innings.
There are also variations in the length of a game of cricket. In professional cricket this ranges from a limit of 20 overs per side (
Twenty20) to a game played over 5 days (
Test cricket, which is the highest level of the game). Depending on the form of the match being played, there are different rules that govern how a game is won, lost, drawn or tied. The rules of two-innings games are known as the
Laws of Cricket and maintained by the ICC and the
Marylebone Cricket Club (MCC); additional Standard Playing Conditions for Test matches and One Day Internationals augment these laws. In one version of
Indoor Cricket, matches include just 6 players per side and include two 12-over innings.
