Each season of The Masked Singer Vietnam includes contestants who are talented singers. The 15 contestants participating in the program will be divided into 3 groups. They will dress up in mascots provided by the show and their true identities are kept hidden throughout their participation. As each character appears, the show will provide an introductory video hint with clues that have a close relationship with that character. The character will then perform a song remixed and performed with his or her real voice. Advisors have the right to ask the character questions to understand more information about the character, and are also provided with other clues about the character so that the advisory board can predict who the character is. During the process of participating in the program until the mask is taken off, except to show their voice, the character will speak in a voice different from the real voice.
