International cricket matches are played between the teams representing their nations, organised by the International Cricket Council (ICC). The main forms are Test matches, One-Day matches and Twenty20 matches.
Most games are played as part 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 ICC Men's Cricket World Cup & ICC Men's T20 World Cup.
