Qualifying for the 2021 World Cup will feature 20 teams, the most to date with 8 teams having automatically qualified. 13 of these teams have never qualified for the world cup with the possibility of 7 of these debutants to reach the tournament proper. 14 teams will take part in the European stage of the qualifying with 4 teams in the Americas group and 3 in the world play-offs where the runner-up of the Americas group will meet the highest ranked teams from Asia/pacific and Africa/middle-east. The Rugby League World Cup has followed a varied range of formats throughout its history as the number of teams participating has increased. The current format has been in use since 2013 featuring 14 teams split into two groups of four and two groups of three. Three teams from the groups of four qualify for the knockout stage and one team from the groups of three qualify. Each team is awarded two points for a win and one point for a draw. The eight teams in the quarter finals play each other with the four winners progressing to the semi finals before the World Cup Final. If the teams are level after 80 minutes extra time will be played and if the two teams are still level after extra time, a golden point will be played. In 2017 the final tournament followed the same format as that of 2013 but this will change for 2021 when the number of teams taking part is increased to 16. Eight teams have officially hosted and co-hosted the World Cup. Only 1975, 1985-88 and 1989-92 were held internationally and not in a specific country. Scotland hosted games in the 2000 world cup but these games were considered to have been hosted by Great Britain rather than the specific home nations. Although games were played in Papua New Guinea during the 1985–88 and 1989-92 World Cups, they are due to officially become the eighth nation to host games in 2017 alongside Australia and New Zealand. In total, 81 stadiums have hosted world cup games over the 14 tournaments. Headingley Stadium in Leeds has hosted the tournament the most times, having had games in 7 world cups with Central Park, Wigan and Lang Park, Brisbane having hosted 6 tournaments. 52 stadiums have hosted matches in just 1 tournament. The most stadiums used in a tournament was in 2000 when 26 stadiums were used; the stadium capacity was the highest ever at 704,400. However, the occupancy was also the lowest ever at just 37.46%. The largest stadium in terms of capacity ever used was Wembley Stadium, London with a seating capacity of 90,000; the stadium was used in the 2013 tournament as the venue for the semi-final double-header.
