International cricket
Most games are played as parts of "tours", when one nation travels to another for a number of weeks or months, and plays a number of matches of various sorts against the host nation. The ICC also organises competitions that are for several countries at once, including the Cricket World Cup & ICC T20 World Cup.
List A cricket
List A cricket is a classification of the limited-overs (one-day) form of the sport of cricket. List A cricket includes One Day International (ODI) matches and various domestic competitions in which the number of overs in an innings per team ranges from forty to sixty, as well as some international matches involving nations who have not achieved official ODI status. Together with first-class and Twenty20 cricket, List A is one of the three major forms of cricket recognised by the International Cricket Council (ICC).
Most Test cricketing nations have some form of domestic List A competition. The scheduled number of overs in List A cricket ranges from forty to sixty overs per side.
