According to original South Korean rules, the guest artist(s) eliminate mystery singers at the end of each round, with the last remaining mystery singer ended up in a duet performance by one of the guest artists.
If the last remaining mystery singer is good, they will have chance to grant a potential contract on any recording label; if a singer is bad, they win RM5,000.
Rounds
Visual round
Each mystery singer is given two different identities as a good and bad singer, with one of them is a real identity.
Lip sync round
The mystery singer lip syncs to the good singer's recording, then a bad singer's recording comes in the middle of the performance.
Rehearsal round
Three random panelists are wearing headphones to listen to a recording of assigned mystery singer that lasts for 15 seconds. Afterward, the panelist defends the mystery singer and convince the guest artist to choose them as the winner.
Also in that season, a fourth singing contest was held with all of winning good singers performing virtually, in which one of them would grant an exclusive contract and a single on any record label; this was determined through judging criteria, consisting of 60% by jury and 40% by public voting via Xtra website.[14]
