Idol Death Game TV is broken down into exploration, judging, and 'Death Concert' elements. During exploration players will look for useful items throughout each stage, as well as exchange information with other 'Project 47' idols. Player interactions may have the effect of altering your confidence or 'spirit,' or doing the same to the other idols. Giving yourself an edge in these interactions will be important for the 'Death Concerts.'
The story focuses on the "Dream of Dream" or D.o.D. competition, which sees potential idols in a contest to take the center position in the Project 47 idol group. However, the 10th D.o.D. competition takes place at Shichibōkan, a mansion nestled deep in the mountains, and will involve the idols fighting for their lives, with the lowest in the popularity rankings executed in a "death game" broadcast on live television.
