Nucksal

Korea’s first high school rap competition program! Only high school students are allowed to participate as contestants in this program where teen rappers get to show off their talent.

The concept of the show is to select a group of promising rappers from open auditions and whittle down that number down through various assignments, with contestant survival dependent on the "producers," a group of experienced rappers who also serve as mentors. Eventually the rappers are divided into small teams headed by those producers. From there each contestant will face a different team's rapper in head-to-head single-elimination rounds where survival in the competition is dependent on votes from a live studio audience. In the third season, there was also a "Revival Round" in which contestants previously eliminated had a chance to continue in the competition.
