Snooker world rankings

The snooker world rankings are the official system of ranking professional snooker players to determine automatic qualification and seeding for tournaments on the World Snooker Tour. They are maintained by the sport's governing body, the World Professional Billiards and Snooker Association. A player's ranking is based on their performances in designated ranking tournaments over the preceding two years, and it is updated after every tournament. The world rankings were inaugurated in the 1976/1977 season and the point tariffs used to be set by the governing body, but the rankings transitioned to a prize money list in the 2014/2015 season.
