Snooker world ranking points 2014/2015: The official 2014/2015 snooker world ranking points for the professional snooker players on the World Snooker Main Tour in the 2014/2015 season are based on performances in ranking and minor-ranking tournaments over a two-year rolling period.  Following an overhaul of the world rankings it is the first season where the tariffs are based on prize money.  Rather than being awarded points according to tariffs preset by the governing body as in previous seasons, the players are now ranked by their prize money earnings in tournaments that carry ranking status.  The only exception to this is when a player loses their first match: for the 2012/2013 and 2013/2014 seasons only half the money earned for the event counts towards the player's ranking,<ref name="2013/2014 points schedule"> </ref> and for the 2014/2015 season a player will not receive any points at all for that tournament.  Due to the transition to the new ranking system, the start ranks of the 2014/2015 season for the top 64 players are incongruent with the ranks of the players at the end of the previous season.
