The rules of the Spanish Basketball Federation establish that the three first teams classified at the end of the first leg, together with the club representing the host province will play the Competition. If the host finishes between the three first teams, the fourth classified will also participate.
The cities of Salamanca, Huelva, Logroño, and San Sebastián bid for hosting the Cup. Finally, on December 17 2015, the Spanish Basketball Federation awarded the organization of the Cup to the city of San Sebastián, qualifying IDK Gipuzkoa as host team. This designation, done less than 48 hours prior to the last game of the first leg, and which left one spot for sporting merits less in the tournament, received critics from some clubs involved in the qualification.
