Main article: End of an innings (cricket)

===============================================

An innings is closed when:

1. Ten of the eleven batsmen are out (have been dismissed); in this case, the team is said to be "all out"
2. 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"
3. The team batting last reaches the score required to win the match
4. The predetermined number of overs has been bowled (in a one-day match only, most commonly 50 overs; or 20 in Twenty20)
5. 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)

Results

Main article: The result in cricket

If the team that bats last is all out having scored fewer runs than their opponents, the team is said to have "lost by n runs" (where n is the difference between the 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 instance a team that passes its opponents' score having only lost six wickets would have won "by four wickets".

In a two-innings-a-side match, one team's combined first and second innings total may be less than the other side's first innings total. The team with the greater score is then said to have won by an innings and n runs, and does not need to bat again: n is the difference between the two teams' aggregate scores.

If the team batting last is all out, and both sides have scored the same number of runs, then the match is a tie; this result is quite rare in matches of two innings a side. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is declared a draw.

If the match has only a single innings per side, then a maximum number of deliveries for each innings is often imposed. Such a match is called a "limited overs" or "one-day" match, and the side scoring more runs wins regardless of the number of wickets lost, so that a draw cannot occur. If this kind of match is temporarily interrupted by bad weather, then a complex mathematical formula, known as the Duckworth-Lewis method after its developers, is often used to recalculate a new target score. A one-day match can also be declared a "no-result" if fewer than a previously agreed number of overs have been bowled by either team, in circumstances that make normal resumption of play impossible; for example, wet weather.

Types of match and competition

===============================

Cricket is a multi-faceted sport which, in very broad terms, can be divided into major cricket and minor cricket based on playing standards. A more pertinent division, particularly in terms of major cricket, is between matches in which the teams have two innings apiece and those in which they have a single innings each. The former, known as first-class cricket, has a duration of three to five days (there have been examples of "timeless" matches too); the latter, known as limited overs cricket because each team bowls a limit of typically 50 overs, has a planned duration of one day only (a match can be extended if necessary due to bad weather, etc.).

Typically, two-innings matches have at least six hours of playing time each day. Limited overs matches often last six hours or more. There are usually formal intervals on each day for lunch and tea with brief informal breaks for drinks. There is also a short interval between innings.

Historically, a form of cricket known as single wicket has been extremely successful and many of these contests in the 18th and 19th centuries qualify as major cricket matches. In this form, although each team may have from one to six players, there is only one batsman at a time and he must face every delivery bowled while his innings lasts. Single wicket has rarely been played since limited overs cricket began.

Test cricket

=============

Test cricket is the highest standard of first-class cricket. A Test match is an international fixture between teams representing those countries that are Full Members of the ICC.
A Test match between South Africa and England in January 2005. The men wearing black trousers on the far right are the umpires. Teams in Test cricket, first-class cricket and club cricket wear traditional white uniforms and use red cricket balls, while professional limited overs teams usually wear multi-coloured uniforms and use white balls.

Although the term "Test match" was not coined until much later, Test cricket is deemed to have begun with two matches between Australia and England in the 1876-77 Australian season. Subsequently, eight other national teams have achieved Test status: South Africa (1889), West Indies (1928), New Zealand (1929), India (1932), Pakistan (1952), Sri Lanka (1982), Zimbabwe (1992) and Bangladesh (2000).

It should be noted Welsh players are eligible to play for England, which is in effect an England and Wales team. The West Indies team comprises players from numerous states in the Caribbean, most notably Barbados, Guyana, Jamaica, Trinidad & Tobago, the Leeward Islands and the Windward Islands.

Test matches between two teams are usually played in a group of matches called a "series". Matches generally last up to five days and a series normally consists of three to five matches. Test matches that are not finished within the allotted time are drawn.

Since 1882, most Test series between England and Australia have been played for a trophy known as The Ashes. Some other series have individual trophies too: for example, the Wisden Trophy is contested by England and West Indies; the Frank Worrell Trophy by Australia and West Indies.
====================================================================
Limited overs
==========
Limited overs cricket is sometimes called "one day cricket" because each match is scheduled for completion in a single day. In practice, matches sometimes continue on a second day if they have been interrupted or postponed by bad weather. The main objective of a limited overs match is to produce a definite result and so a conventional draw is not possible, but matches can be undecided if the scores are tied or if bad weather prevents a result. Each team plays one innings only and faces a limited number of overs. Typically, the limit is 40 or 50. In Twenty20 cricket, each team faces 20 overs only.

Standard limited overs cricket was introduced in England in the 1963 season in the form of a knockout cup contested by the first-class county clubs. In 1969, a national league competition was established. The concept was gradually introduced to the other major cricket countries and the first limited overs international was played in 1971. In 1975, the first Cricket World Cup took place in England. Limited overs cricket has seen various innovations including the use of multi-coloured kit and floodlit matches using a white ball.

Twenty20 is a new variant of limited overs itself with the purpose being to complete the match within about three hours, usually in an evening session. The original idea, when the concept was introduced in England in 2003, was to provide workers with an evening entertainment. It has been commercially successful and has been adopted internationally. The inaugural Twenty20 World Championship was held in 2007.
=====================================================================

National championships

First-class cricket includes Test cricket but the term is generally used to refer to the highest level of domestic cricket in those countries with full ICC membership, although there are exceptions to this. First-class cricket in England is played for the most part by the 18 county clubs which contest the County Championship. The concept of a champion county has existed since the 18th century but the official competition was not established until 1890. The most successful club has been Yorkshire County Cricket Club with 30 official titles.

Australia established its national first-class championship in 1892-93 when the Sheffield Shield was introduced. In Australia, the first-class teams represent the various states. New South Wales has won the most titles with 45 to 2008.

National championship trophies to be established elsewhere included the Ranji Trophy (India), Plunket Shield (New Zealand), Currie Cup (South Africa) and Shell Shield (West Indies). Some of these competitions have been updated and renamed in recent years.

Domestic limited overs competitions began with England's Gillette Cup knockout in 1963. Countries usually stage seasonal limited overs competitions in both knockout and league format. In recent years, national Twenty20 competitions have been introduced, usually in knockout form though some incorporate mini-leagues.
==============================================================

Minor Cricket
==========
Various leagues, often organised on a state, county or regional basis, that include clubs which are classed as "minor" although in many cases the playing standards are anything but minor. Give examples like Australia's grade structure and the Minor Counties Championship.

Village cricket and significant local leagues like the Lancashire League.

Other types of cricket

Main article: Forms of cricket

There are numerous informal variations of the sport played throughout the world that include indoor cricket, French cricket, beach cricket, Kwik cricket and all sorts of card games and board games that have been inspired by cricket. In these variants, the rules are often changed to make the game playable with limited resources or to render it more convenient and enjoyable for the participants.

Indoor cricket is played in a netted, indoor arena, and is quite formal but most of the outdoor variants are very informal.Families and teenagers play backyard cricket in suburban yards or driveways, and the teeming cities of India and Pakistan play host to countless games of "Gully Cricket" or "tapeball" on their streets (played in long narrow streets) with rules like the one bounce catch. Such rules and, usually, lack of space ensure the batsmen have to play cautiously. Tennis balls and homemade bats are often used, and a variety of objects may serve as wickets: for example, the batter's legs as in French cricket, which did not in fact originate in France, and is usually played by small children. Sometimes the rules are improvised: e.g., it may be agreed that fielders can catch the ball with one hand after one bounce and claim a wicket; or if only a few people are available then everyone may field while the players take it in turns to bat and bowl.

In Kwik cricket, the bowler does not have to wait for the batsman to be ready before a delivery, leading to a faster, more exhausting game designed to appeal to children, which is often used PE lessons at English schools. Another modification to increase the pace of the game is the "Tip and Run", "Tipity" Run, "Tipsy Run" or "Tippy-Go" rule, in which the batter must run when the ball touches the bat, even if it the contact is unintentional or minor. This rule, seen only in impromptu games, speeds the match up by removing the batsman's right to block the ball.

In Samoa a form of cricket called Kilikiti is played in which hockey stick-shaped bats are used. In original English cricket, the hockey stick shape was replaced by the modern straight bat in the 1760s after bowlers began to pitch the ball instead of rolling or skimming it.

In Estonia, teams gather over the winter for the annual Ice Cricket tournament. The game juxtaposes the normal summer pursuit with harsh, wintry conditions. Rules are otherwise similar to those for the six-a-side game.
