Twelve entries competed in the quarter-finals, with three entries taking part in each show. The favourite entry from each quarter-final advanced directly to the semi-finals. Among the four semi-finalists, only two entries made it to the final.

Voting
The voting consisted in the South Korean jury votes and the public votes. The South Korean jury's votes influenced the results only at 25%, while the remaining 75% was determined by the public votes.

These groups were weighted equally against each other: for the quarter-finals, each group's vote would carry a score of 3, 2, and 1; for the semi-finals and the final, each group gave one point to the most popular entry of each duel.
