The Men's Rugby World Cup is an international rugby union tournament held every four years, featuring 20 participating nations that compete in a pool stage followed by knockout rounds. The host country is typically placed in Pool A, and the tournament uses world rankings for seeding. The competition culminates in crowning a world champion and includes a bronze final match. In the event of a tied knockout game, the teams proceed to extra time, and if necessary, a sudden death decision is made. Historically, the tournament has alternated venues, and the finals are often held in autumn months, typically in a European country.
