The cup was played over the weekend. In the usual traditional format, a team from the second division joins the top five teams in the first division. The University of Gdansk was that team this year, losing to Bydgoszcz 88-56 in the first game on Friday. Angelika Stankiewicz and Torun then beat Gorzow 89-79. Polkowice entered the competition on Saturday as the top two teams got byes and eased past Bydgoszcz 78-45. The other semifinal was much closer as Alice Kunek and Torun beat Emma Cannon and Gdynia 68-66. On Sunday, Torun had the tough task of trying to win three games in three days and Polkowice proved to be too much as they won 66-45 and sent a message to the rest of the league after a small slump in league play.
