[1] Michael van Gerwen won his 16th World Series event defeating Fallon Sherrock 11–7 in the final.

Van Gerwen won his first title overall in 2021, ending a 292 days streak without any tournament win.

[2] This was the first World Series of Darts event held in Scandinavia, after the 2020 tournament had to be postponed due to the COVID-19 pandemic.

The eight invited PDC representatives were announced on 1 September, with the top four ranked players being seeded in the draw.

The four PDCNB Tour Card holders who were given their places for the original 2020 tournament kept their places (even though Marko Kantele had since lost his Tour Card), the three highest ranked Danish players after the PDCNB Tour events in Iceland on 19–21 August also qualified, and so did the winner of a PDCNB qualifier on 22 August.
