The Page playoff system is a playoff format used primarily in softball and curling at the championship level, the Indian Premier League and Pakistan Super League cricket tournaments. Teams are seeded using a round-robin tournament and the top four play a mix of a single-elimination and double-elimination tournament to determine the winner. It is identical to a four-team McIntyre system playoff, first used by the WANFL, SANFL and VFL in Australia in 1931, originally called the Page–McIntyre system, after the VFL delegate, the Richmond Football Club's Secretary, Percy "Pip" Page, who had advocated its use. History The Page playoff system was used at the Australian Rugby League Championship 1954–1972. In Australia, its most notable use today is in netball, having been adopted by Suncorp Super Netball when it began play in 2017. The system has been used since 1990 by the International Softball Federation and its successor, the World Baseball Softball Confederation, for the Women's Softball World Championship and from 1996 to 2008 at the Olympic Games. Its first use in curling was by the Canadian Curling Association in the 1995 Labatt Brier, the men's championship, and was adopted the next year at the 1996 Scott Tournament of Hearts, the women's championship. It gained acceptance and in 2005 the World Curling Championships started using it until 2018 when the playoff format was switched to re-seeding 6 team single-elimination. It has not yet been adopted in curling at the Olympic Games. The format is used in the Indian Premier League cricket tournament since 2011. The format has also been used in some much lower-key, internet gaming events, such as chess and backgammon. Beginning with the 2020 season, the League of Legends Championship Series uses a double-elimination format with a Page playoff system being employed for the final rounds of the playoff tournament. A similar format would also be adopted for the League of Legends European Championship that same year. The 2021 playoffs saw the National Basketball Association use the system for its Play-In Tournament. It featured teams ranked 7th–10th in their respective conferences during the regular season. The winner of the 7–8 game advanced to the playoffs as the seventh seed, while the loser played in the preliminary final game against the winner of the 9–10 game for the eighth seed. This meant the 7th and 8th place teams have two chances to win once, while the 9th and 10th place
