Three men and three women are sequestered in separate wings of the house, unable to have any conversation or contact with the opposite sex unless in the dark room.
Initially, all six contestants have a group date in which they all sit at a table in the dark room exchanging names and getting to know one another's voices and personality types.
Throughout the show, the host provides the men and women with additional insights by providing personality profiles showing which contestants are their best matches and also allowing them to view items the others have brought to the house, such as items of clothing or luggage.
Each contestant is standing at opposite ends of the dark room with a very large two-way mirror between them.
A separate infrared camera films the person on the dark side's reaction; the two images are combined in post-production.
