Due to the adoption of 12 finalists in Superstar K4 compared to 10 and 11 finalists in the previous seasons, the format was changed by which three finalists are eliminated in the first week, and two in the following three weeks till the Top 5 is reached (exceptions including the judges decision to save DickPunks in the Top 7 week). Judge PSY was replaced from the Top 9 week by singer Yoon Gun, due to his decision to commit to promoting his song 'Gangnam Style (강남스타일)' overseas. The elimination of a contestant will be determinant upon who has the lowest number of points: with 60 percent of the points from a live text poll, 30 percent from the judges' decision and 10 percent from a pre-broadcast online poll.
