The batsman on strike (i.e. the "striker") must prevent the ball hitting the wicket, and try to score runs by hitting the ball with his bat so that he and his partner have time to run from one end of the pitch to the other before the fielding side can return the ball. To register a run, both runners must touch the ground behind the popping crease with either their bats or their bodies (the batsmen carry their bats as they run). Each completed run increments the score of both the team and the striker.[106]
The ICC also organises competitions that are for several countries at once, including the Cricket World Cup, ICC T20 World Cup and ICC Champions Trophy. A league competition for Test matches played as part of normal tours, the ICC World Test Championship, had been proposed several times, and its first instance began in 2019. A league competition for ODIs, the 2020–22 ICC Cricket World Cup Super League, is planned to begin in 2020. The ICC maintains Test rankings, ODI rankings and T20 rankings systems for the countries which play these forms of cricket.
The game on the field is regulated by the two umpires, one of whom stands behind the wicket at the bowler's end, the other in a position called "square leg" which is about 15–20 metres away from the batsman on strike and in line with the popping crease on which he is taking guard. The umpires have several responsibilities including adjudication on whether a ball has been correctly bowled (i.e., not a no-ball or a wide); when a run is scored; whether a batsman is out (the fielding side must first appeal to the umpire, usually with the phrase "How's that?" or "Owzat?"); when intervals start and end; and the suitability of the pitch, field and weather for playing the game. The umpires are authorised to interrupt or even abandon a match due to circumstances likely to endanger the players, such as a damp pitch or deterioration of the light.[67]
Although the main object of the game has always been to score the most runs, the early form of cricket differed from the modern game in certain key technical aspects. The ball was bowled underarm by the bowler and all along the ground towards a batsman armed with a bat that, in shape, resembled a hockey stick; the batsman defended a low, two-stump wicket; and runs were called "notches" because the scorers recorded them by notching tally sticks.[13][14][15]

Most bowlers are considered specialists in that they are selected for the team because of their skill as a bowler, although some are all-rounders and even specialist batsmen bowl occasionally. The specialists bowl several times during an innings but may not bowl two overs consecutively. If the captain wants a bowler to "change ends", another bowler must temporarily fill in so that the change is not immediate.[82]
The folklore and mythology surrounding crickets is extensive.[36] The singing of crickets in the folklore of Brazil and elsewhere is sometimes taken to be a sign of impending rain, or of a financial windfall. In Álvar Núñez Cabeza de Vaca's chronicles of the Spanish conquest of the Americas, the sudden chirping of a cricket heralded the sighting of land for his crew, just as their water supply had run out.[37] In Caraguatatuba, Brazil, a black cricket in a room is said to portend illness; a gray one, money; and a green one, hope.[37] In Alagoas state, northeast Brazil, a cricket announces death, thus it is killed if it chirps in a house.[38] In Barbados, a loud cricket means money is coming in; hence, a cricket must not be killed or evicted if it chirps inside a house. However, another type of cricket that is less noisy forebodes illness or death.[39]
Limited overs cricket is always scheduled for completion in a single day. There are two types: List A which normally allows fifty overs per team; and Twenty20 in which the teams have twenty overs each. Both of the limited overs forms are played internationally as Limited Overs Internationals (LOI) and Twenty20 Internationals (T20I). List A was introduced in England in the 1963 season as 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 leading cricket countries and the first limited overs international was played in 1971. In 1975, the first Cricket World Cup took place in England. 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 first Twenty20 World Championship was held in 2007. Limited overs matches cannot be drawn, although a tie is possible and an unfinished match is a "no result".[120][121]
A match's statistics are summarised on a scorecard. Prior to the popularisation of scorecards, most scoring was done by men sitting on vantage points cuttings notches on tally sticks and runs were originally called notches.[84] According to Rowland Bowen, the earliest known scorecard templates were introduced in 1776 by T. Pratt of Sevenoaks and soon came into general use.[85] It is believed that scorecards were printed and sold at Lord's for the first time in 1846.[86]
The patrons, and other players from the social class known as the "gentry", began to classify themselves as "amateurs"[fn 1] to establish a clear distinction vis-à-vis the professionals, who were invariably members of the working class, even to the point of having separate changing and dining facilities.[29] The gentry, including such high-ranking nobles as the Dukes of Richmond, exerted their honour code of noblesse oblige to claim rights of leadership in any sporting contests they took part in, especially as it was necessary for them to play alongside their "social inferiors" if they were to win their bets.[30] In time, a perception took hold that the typical amateur who played in first-class cricket, until 1962 when amateurism was abolished, was someone with a public school education who had then gone to one of Cambridge or Oxford University – society insisted that such people were "officers and gentlemen" whose destiny was to provide leadership.[31] In a purely financial sense, the cricketing amateur would theoretically claim expenses for playing while his professional counterpart played under contract and was paid a wage or match fee; in practice, many amateurs claimed somewhat more than actual expenditure and the derisive term "shamateur" was coined to describe the syndrome.[32][33]
Crickets have from time to time appeared in poetry. William Wordsworth's 1805 poem The Cottager to Her Infant includes the couplet "The kitten sleeps upon the hearth, The crickets long have ceased their mirth".[46] John Keats's 1819 poem Ode to Autumn includes the lines "Hedge-crickets sing; and now with treble soft / The redbreast whistles from a garden-croft".[47] The Chinese Tang dynasty poet Du Fu (712–770) wrote a poem that in the translation by J. P. Seaton begins "House cricket ... Trifling thing. And yet how his mournful song moves us. Out in the grass his cry was a tremble, But now, he trills beneath our bed, to share his sorrow."[48]
