Format According to the
original South Korean rules, the guest artist must attempt to eliminate bad singers during its game phase. At the final performance, the last remaining mystery singer is revealed as either good or bad by means of a duet between them and one of the guest artists. For this season, the
Golden Switch () can be used by panelists during the proper game phase to apply one randomly-selected mystery singer as an additional hint; the guest artist(s) could still eliminate that, even if they are revealed as good or bad. The winning mystery singer, regardless of being good or bad, gets 5,000
лв (2558,60
€) and will have to perform again at the encore concert.
