[1] The first edition was in 2018,[2] which was also the temporary only edition after the International Hockey Federation decided to discontinue the FIH Series after 2019 and from 2022, will be replaced by men's and women's Intercontinental Cups, the new FIH tournament.

[3] The Hockey Series was open to national teams that were not playing in the Men's or Women's FIH Pro League.

The Hockey Series took place in two rounds, the Open and the Finals.

The nine highest-ranked teams in the FIH World Rankings (on 9 June 2017) skipped the Open and advanced directly to the Finals.

The teams will be drawn and play a two-legged tie to determine six qualified nations for the Olympic Games.
