Usually, during or after each episode's recording, there will be a short live stream through Idol Room's Naver V Live channel that acts as a teaser to the episode. This was not available anymore after episode 41.

Studio Set

The studio sets used are as follow:

Episodes 1-8: Black room with a large landscape screen at the background

Episodes 9-51: Beige room with a tall portrait screen at the back

Episode 52-87: Pink room with a landscape screen at the back

In some special episodes, the 2 hosts will go outdoors.

Theme Song

There are two theme songs for the show, one being produced by Pentagon's Hui and the other being produced by (G)I-DLE's Soyeon. In episode 5, where they appeared with their groups, they each were tasked with composing a theme song for the show. The theme songs will be played at the start of each alternate episode, beginning from episode 7 with Hui's produced theme song, and episode 8 with Soyeon's produced theme song. This has been discontinued since the introduction of Idol 999.

A third theme song, which is produced by N.Flying's Lee Seung-hyub, was performed live by the band at the start of episode 42.

Featured Corners

Idol 999 Forced Auditions: This is the program's new project which started on episode 52. It lets the 2 hosts find 999 idol group members and form the co-ed group 1001 (read as "One Oh Oh One") together. Every week, the guest(s) will undergo individual and group evaluations throughout the episode, and at any point of time the 2 hosts can give or take away grade(s) from each guest. The final grade of each guest can be of a single grade (e.g. A or B), or multiple grades (e.g. AA or ABF). The final member to be picked for Idol 999 will be selected through the Bomb Dance. When the balloon bursts while this member was holding it, even when they were in the middle of the handover, that member will become the selected idol to join Idol 999. There are other procedures done to choose the idol to join Idol 999:

For episode 54, instead of the Bomb Dance, the Bomb Interview is used as selection. The guests will pass down the bomb after saying a sentence, and this will be done continuously until the balloon bursts and the guest holding it when it bursts is the selected idol to join Idol 999.

For episode 55, where there is only Jeon So-mi taking part in the audition, the rendition of the game "He loves me... he loves me not" is played to decide whether she will join Idol 999 or not.

For episode 58, where there is only Eun Ji-won taking part in the audition, he will draw lots to decide whether he will join Idol 999 or not.

For episode 60, the members of NCT Dream will do 10 elephant spins and each will attempt to touch Don Hee's finger with his finger. The first member to touch will be the member of Idol 999.

For episode 64, the members of Pretty 95s will each compete against Don Hee for pulling the Couple Bar ice cream in half, and the member with the bigger portion pulled out will be the member of Idol 999.

For episode 65, Apink members Park Cho-rong and Kim Nam-joo will have to push fellow member Oh Ha-young, who was sitting on the hyodo chair, to the target and whether she lands on the target or not will decide whether she will join Idol 999 or not.
