Ball Bat Stumps Wicket
Standard laws of cricket apply to this form with some exceptions being that both teams have a single inning and bat for a maximum of twenty overs. Each bowler may bowl a maximum of only one-fifth of the total overs per innings (generally four, for a full, uninterrupted game). Umpires may award five-run penalty runs at their discretion if they believe either team is wasting time. If the fielding team does not start to bowl their 20th over within 75 minutes, the batting side is credited an extra six runs for every whole over bowled after the 75 minute mark; the umpire may add more time to this, if he considers the batting team is wasting time. If the match ends with the scores tied and there must be a winner, the tie is broken with a bowl-out (similar to a penalty shoot-out in football), with five bowlers from each side delivering 1 ball each at an unguarded wicket. If the number of wickets is equal after the first five balls per side, the bowling continues and is decided by sudden death. Should a bowler deliver a no ball by overstepping the popping crease, it costs 1 run and his next delivery is designated a free-hit, from which the batsman can only be dismissed through a run out, for hitting the ball twice, obstructing the field or handling the ball, as is the case for the original "no ball."
Twenty Cricket is the shortest (duration wise) version of cricket, with matches usually lasting around three hours. Twenty cricket is a modified version of traditional cricket. Twenty cricket consists of only one inning per team and a maximum of 20 batsmen per team, thus resulting in a much shorter game lasting around three hours.
Twenty cricket originated sometime in 2003 as a way to shorten the length of the game, create a livelier form of the game, and be a more attractive form to spectators. The first game of twenty cricket was played on July 15, 2004 between Middlesex and Surrey. The first international game was not played until Australia defeated New Zealand on February 17, 2005. Since that match, 12 countries have participated in the format. The ICC has set a world tournament of twenty to occur every two years. The inaugural tournament was played in 2007 and won by India.
