Gerwyn Price won the tournament for the third time in four years, defeating Peter Wright 16–8 in the final.[2]
Due to the dissolution of the British Darts Organisation in 2020, there was no BDO/WDF representation for the first time in the event's history.[3]
During her 5–0 victory over Mike De Decker in the group stage, Fallon Sherrock averaged 101.55, setting a new record for the highest televised average by a woman.[4] She then went on to become the first woman to advance to the knockout stage, where she defeated Mensur Suljović in the second round, before losing to Peter Wright in the quarterfinals.
The prize fund for the Grand Slam was the same as 2019 and 2020, with the winner receiving £125,000.[5]

Qualifying
The qualification criteria changed again for the 2021 tournament, as there were no Summer, Autumn or Winter Series events, as well as no Home Tour, and no events organized by the BDO, which dissolved in 2020. The addition of qualifiers from the PDC Challenge and Development Tours replaced BDO representation.[3]
On 11 November, it was announced that Dimitri Van den Bergh had tested positive for COVID-19, ruling him out of the tournament. He was replaced by Chris Dobey, who was next on the list of qualifying criteria.[6]
Note: Players in italics had already qualified for the tournament.
Since the list of qualifiers from the main tournaments produced fewer than the required number of 16 players, the field was to be filled from the reserve lists. The first list consisted of the winners from 2021 European Tour events, with the winners ordered based on Order of Merit position at the cut-off date. However, Gerwyn Price, who had already qualified, won both European Tour events, and thus this list produced no new competitors.
Note: Players in italics had already qualified for the tournament.
Since there were still fewer than 16 qualifiers after European Tour champions were included, the players with the most 2021 Players Championship titles were added. Order of Merit position served as a tiebreaker.
^Rafferty qualified as 2nd of the Development Tour Order of Merit after Bradley Brooks was already qualified.
^Ashton qualified as 2nd of the Women's Series 7–12 Order of Merit after Fallon Sherrock was already qualified.

The draw was made on 5 November, with the players split into 4 pools based on their current world ranking.[7]
