Initially twenty-five teams signed up for the Cup tournament. In October 2020, the tournament was postponed, first for two weeks and later indefinitely due to another Coronavirus outbreak in Iceland. On 28 January 2021, KKÍ announced that the competition would begin on 22 April and end on 1 May, featuring 16 teams and would be sponsored by the insurance company VÍS. It was later postponed to August 2021 with the first game played on 28 August.
