The World Cup of Pool is an annual international single-elimination tournament for doubles teams in nine-ball pool competition.
There are usually 32 participating teams, representing 31 nations (the host nation is represented by two teams, A and B) composed of two players each.
The participating nations do not have to go through a qualifying tournament in order to join, as they are selected by the organizers.
The individual matches are scotch doubles with alternating break, which are races to seven racks for Round 1 and 2, nine racks for the quarterfinals and semifinals, and eleven for the final.
The rules used are World Pool-Billiard Association (WPA) World Standardized Rules for nine-ball, modified for scotch doubles play (players on a team alternate shots; no one shoots twice in a row, unless being asked to play again after pushing out).
