24 countries in the PDC Order of Merit on 1 January after the 2013 PDC World Darts Championship were represented at the 2013 PDC World Cup of Darts. Each nation's top ranked player was joined by the second highest player of that country. For seeding the average rankings of the players was used, with the top eight seeds heading each of the eight groups of three countries.[1]
The 24 countries were separated into eight groups of three. Each team played one best of nine leg match against the other two in their group. The top two from each group advanced to the last 16 where the tournament became a straight knockout bracket.
Group matches and Last 16: best of nine legs doubles. Quarter-finals and semi-finals: 2 best of seven legs singles matches. Should the tie be 1–1, then a third and final doubles tie will be played. Final: Up to the four best of seven legs singles matches. First team to 3 points wins the title. Should the tie be 2–2, then a fifth and final doubles tie will be played.
Three match wins were needed to win the title. Two best of seven legs singles matches were played, followed by reverse singles matches. If the score had been level after that, a best of seven legs doubles match would have been played to determine the champion.
