Under the guidance of seven "Masters", contestants had to go through several rounds of evaluation, during which they had to show off their skills in singing, dancing, and rapping.
After each round, the audience, known as "Star Creators", voted for their favorite trainees, determining the final debut line-up.
While its predecessor, Girls Planet 999, limited applications to South Korea, Japan, China, and Taiwan, the regions were expanded this season to allow for international participation.
The final contestants were chosen regardless of nationality, affiliation with an agency, or prior experience and professional history as a singer.
