The games movement consists of international sports federations (IFs),  (CGAs), and organising committees for each specific Commonwealth Games. There are several rituals and symbols, such as the Commonwealth Games flag and Queen's Baton, as well as the opening and closing ceremonies. Over 5,000 athletes compete at the Commonwealth Games in more than 15 different sports and more than 250 events. The first, second, and third-place finishers in each event receive Commonwealth Games medals: gold, silver, and bronze, respectively. Apart from many Olympic sports, the games also include some sports that are played predominantly in Commonwealth countries, such as lawn bowls and netball.
