Format of the game

A cricket match is divided into periods called innings. During an innings (innings ends with "s" in both singular and plural form), one team fields and the other bats. The two teams switch between fielding and batting after each innings. All eleven members of the fielding team take the field, but only two members of the batting team (two batsmen) are on the field at any given time.

The two batsmen face each other at opposite ends of the pitch, each behind a line on the pitch known as a crease. The fielding team's eleven members stand outside the pitch, spread out across the field.Behind each batsman is a target called a wicket. One designated member of the fielding team, called the bowler, is given a ball, and attempts to bowl the ball from one end of the pitch to the wicket behind the batsman on the other side of the pitch. The batsman tries to prevent the ball from hitting the wicket by striking the ball with a bat. If the bowler succeeds in hitting the wicket, or if the ball, after being struck by the batsman, is caught by the fielding team before it touches the ground, the batsman is dismissed. A dismissed batsman must leave the field, to be replaced by another batsman from the batting team.

If the batsman is successful in striking the ball and the ball is not caught before it hits the ground, the two batsmen may then try to score points (runs) for their team by running across the pitch, grounding their bats behind each other's crease. Each crossing and grounding by both batsmen is worth one run. The batsmen may attempt one run, multiple runs, or elect not to run at all. By attempting runs, the batsmen risk dismissal, which can happen if the fielding team retrieves the ball and hits a wicket with the ball before either batsman reaches the opposite crease.

If the batsman hits the bowled ball over the field boundary without the ball touching the field, the batting team scores six runs and may not attempt more. If the ball touches the ground and then reaches the boundary, the batting team scores four runs and may not attempt more. When the batsmen have finished attempting their runs, the ball is returned to the bowler to be bowled again. The bowler continues to bowl toward the same wicket, regardless of any switch of the batsmen's positions.

After a bowler has bowled six times (an over), another member of the fielding team is designated as the new bowler. The new bowler bowls to the opposite wicket, and play continues. Fielding team members may bowl multiple times during an innings, but may not bowl two overs in succession.

The innings is complete when 10 of the 11 members of the batting team have been dismissed, one always remaining "not out", or when a set number of overs has been played. The number of innings and the number of overs per innings vary depending on the match.

Playing surface

Cricket is played on a grassy field. The Laws of Cricket do not specify the size or shape of the field, but it is often oval. In the centre of the field is a rectangular strip, known as the pitch.
The pitch is a flat surface 10 feet (3.0 m) wide, with very short grass that tends to be worn away as the game progresses. At either end of the pitch, 22 yards (20 m) apart, are placed wooden targets, known as the wickets. These serve as a target for the bowling (also known as the fielding) side and are defended by the batting side, which seeks to accumulate runs.

Team structure

A team consists of eleven players. Depending on his or her primary skills, a player may be classified as a specialist batsman or bowler. A well-balanced team usually has five or six specialist batsmen and four or five specialist bowlers. Teams nearly always include a specialist wicket-keeper because of the importance of this fielding position. Each team is headed by a captain who is responsible for making tactical decisions such as determining the batting order, the placement of fielders and the rotation of bowlers.

A player who excels in both batting and bowling is known as an all-rounder. One who excels as a batsman and wicket-keeper is known as a "wicket-keeper/batsman", sometimes regarded as a type of all-rounder. True all-rounders are rare as most players focus on either batting or bowling skills.

Innings closed

An innings is closed when:

-  Ten of the eleven batsmen are out (have been dismissed); in this case, the team is said to be "all out"
-  The team has only one batsman left who can bat, one or more of the remaining players being unavailable owing to injury, illness or absence; again, the team is said to be "all out"
-  The team batting last reaches the score required to win the match
-  The predetermined number of overs has been bowled (in a one-day match only, commonly 50 overs; or 20 in Twenty20)
-  A captain declares his team's innings closed while at least two of his batsmen are not out (this does not apply in one-day limited over matches)
