Through the event, Turkey posted three victories against Denmark, Estonia and Italy, enough to finish in seventh place in the group. This seventh-place finish was enough to earn them a direct spot into the 2022 World Women's Curling Championship, the first time Turkey ever qualified for a men's or women's world championship.^[8] Next was the Olympic Qualification Event, held from 5 to 18 December in Leeuwarden, Netherlands. Şengül, with teammates Dilşat Yıldız, Öznur Polat, Ayşe Gözütok and Mihriban Polat, finished 3–5 through the round robin.

However, because their two victories came against these two teams, they finished eighth overall and earned qualification into the 2024 World Women's Curling Championship for a third straight year.^[16] In the new year, the team competed in the 2024 Cortina Curling Cup where they defeated higher ranked teams such as Stefania Constantini, Marianne Rørvik and Xenia Schwaller en route to claiming Turkey's first women's World Curling Tour event title.^[17] At the World Championship, the team had a slow start and never recovered, finishing with a 3–9 record and tenth place overall.^[18] Notability, the team gave Canada's Rachel Homan one of their toughest games of the event.^[19] With Turkey leading by one in the tenth, Homan needed a precise runback for the victory, which she made.^[20]
