In an October 1 post, Supercell described invitations to BSC 2027 and selection through the Invitational. There is a pathway for new teams through the Championship Challenge and Challengers.
In the four listed regions, six teams each receive a direct invitation based on the final standings in 2026, and two more places are determined by the Invitational. A direct invitation requires maintaining the core of the squad with a limit on substitutions. RSVP is scheduled by December 20, Invitational - January 16-17, 2027; the authors note that timing may change. Mainland China conditions are promised in a separate publication, so the rules of these four regions cannot be presented as fully confirmed for China. To participate, check the current regulations.
