[3] Reanne Evans was the defending champion, having defeated Nutcharut Wongharuthai 6–3 in the 2019 final to win her 12th women's world title.

[4] However, Evans lost 1–4 to Wendy Jans in the quarter-finals, the first time in her career that she had not reached the semi-finals of the tournament.

[5][6] The quarter-final losses by Evans and Ng meant that no former champion reached the semi-finals.

[9] Wongharuthai later stated: "When I was 5–3 behind I thought that I had lost, and I really just started to play for fun because I was too tense.

[14] Jans then potted the brown, blue, and pink, but missed a long black into the yellow pocket, leaving it over the middle.
