The sport of professional snooker has had a world ranking system in place since 1976. Certain tournaments were given "ranking" status, with the results at those events contributing to a player's world ranking. The events that made up the 1976–77 snooker season were the first to award players with ranking points. Originally, the world rankings were decided based only on results in the World Snooker Championship, but other events were later added. The system used for the 2023–24 snooker season was first used in the 2010–11 season, where players won ranking points based entirely on prize money won from these events. The rankings are based on the prior two seasons, with eight revisions after specific tournaments throughout the season. These revisions are used as official rankings, with points awarded in the current season overwriting those from two years prior.
Ronnie O'Sullivan began the season as the highest ranked player; however, Mark Allen became world number one after the 2024 World Snooker Championship. Allen finished the season with a lead of 54,000 points over Judd Trump.
Revision dates and seeding cut-offs The world rankings are updated at specific revision dates following each ranking tournament. On these dates, the ranking points from the latest 2023–24 season ranking event are added, while those from two years ago in the 2021–22 snooker season are removed from a player's total. The revision dates are also used for seeding of following ranking events.
