Three teams, with no set geographical base, competed in the first tournament: Dragons, Scorchers and Typhoons.

[2] The following season, 2016, the tournament followed a similar format, albeit with teams only playing two T20 matches each, and was newly sponsored by Toyota Ireland.

[4] 2017 saw the number of games per team expand to 10, and Scorchers won their second title.

[5] The same format was kept for the 2018 and 2019 tournaments, and Dragons won both competitions, claiming their second and third titles.

[6][7] In 2020, the tournament format was changed due to the impact of the COVID-19 pandemic: the number of teams was reduced to two (Scorchers and Typhoons) due to player unavailability during the pandemic, and the schedule was condensed, with only 50-over cricket taking place.
