National championships

Yorkshire County Cricket Club in 1895. The team won the first of its 30 County Championship titles in 1893.

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 Shieldwas 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.

Other types 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.

Children playing cricket on a makeshift pitch in a park. It is common in many countries for people to play cricket on such pitches and makeshift grounds.

Families and teenagers play backyard cricket in suburban yards or driveways, and the cities of India and Pakistan play host to countless games of "Gully Cricket" or "tapeball" in their long narrow streets. 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. 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.

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.
