Format According to the
original South Korean rules, the guest artist and contestant 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. The contestant must eliminate one mystery singer at the end of each round, receiving if they eliminate a bad singer. At the end of a game, if the contestant decides to walk away, they will keep the money had won in previous rounds; if they decide to risk for the last remaining mystery singer, they win if a singer is good, or lose their all winnings if a singer is bad.
