The tournament format is identical to that since 2013. During the first nine weeks (Phase 1) each player plays the other nine players once. The bottom two players are then eliminated from the competition. In the next six weeks (phase 2) each player plays the other seven players once. Phase 2 consists of four weeks where five matches are played followed by two weeks where four matches are played. At the end of phase 2 the top four players contest the two semi-finals and the final in the play-off week.
The players in this year's tournament were announced following the 2017 PDC World Darts Championship final on 2 January 2017, with the top four of the PDC Order of Merit joined by six Wildcards - two chosen by Sky Sports and four by the PDC.
Previous PDC wildcards Robert Thornton and Michael Smith were dropped in favour of Jelle Klaasen and Kim Huybrechts. The 2017 edition marks the first time in which the six-time champion Phil Taylor appears as a wildcard entry, having finished outside the Order of Merit places. It is also the first Premier League without a player making his debut in the competition.
*Michael van Gerwen was originally scheduled to play against James Wade, but withdrew due to a back injury, Dave Chisnall played twice in Round 5. Van Gerwen will play Wade on 23 March (Round 8), giving Chisnall the night off.[2]
After the first nine weeks (phase 1), the bottom two in the table are eliminated. In the next six weeks (phase 2) the eight remaining players each play a further seven matches. The top four players then compete in the playoffs.
Two points are awarded for a win and one point for a draw. When players are tied on points, leg difference is used first as a tie-breaker, after that legs won against throw and then tournament average.
