Performers are visible on the stage and give a brief bio of themselves before singing, while the famous relative is concealed within "the sphere", a large half-circle in the middle of the set.

During the performer's intro, contestants need to listen carefully in the event that they might give some verbal clues to their celebrity relative's identity.

Prize money for the first round is $20,000 and is split among all contestants who correctly guess the celebrity relative.

After the contestant interviews are complete, the performer and their celebrity relative begin the same duet again, this time for the reveal.

After the first couple of lines of the song, the singing stops, but the music continues as the two halves of the sphere start to open.

Once the pair have left the stage, the host reveals how many of the 100 contestants correctly guessed the identity of the celebrity relative, and therefore split the $20,000 prize for round one.

Prize money for the second round is raised to $30,000 and is once again split among all contestants who correctly guess the celebrity relative of the second performer.
