13 people will visit the X Manor. A murder will happen and you have to collect clues to solve what happened. One out of the 13 will be named the murderer.   How this will work is, you will have the option of investigating 1 of 3 places. The 3 places are the crime scene, the last known whereabouts, or the morgue containing the victim's body. Guests then participate in a riddle challenge that leads them in a competitive search through the mansion. The guest who is able to complete the challenge receives an additional clue that may greatly help in solving how the murder was committed. Guests are given limited opportunities to congregate, where they can share, withhold, or lie about whatever information they find from their investigations and riddle challenges; at all other times, guests are isolated from each other. Though the murders and riddle challenges are presented as having been masterminded by the killer, in reality the guest playing the killer is as unaware of upcoming deaths and challenges as the other guests, and is not given any information from production about the larger social game. Later, guests are individually taken to the mansion library where, in monologue, they describe to the the Host [Me] how they believe the murder took place and make an accusation as to who the killer is. However, each elimination is actually based how close the guests story is to the actual story. The message states which guest had the most correct theory and is subsequently spared from being the killer's next victim. The message then fully explains how the murder was completed. After this, I will hand an envelope to each remaining guest. Those receiving cards with the word "Spared" performed well enough to advance to the next episode. The lowest-scoring guest, along with at least one other low-scoring guest will receive a card with the word "Scared." As noted above, the guest playing the killer is as unaware of how the murders are committed as the rest of the guests are, and so may also receive a "Scared" card as well; however, the killer cannot be eliminated.The lowest-scoring guest is then eliminated from the competition by being "murdered by the killer", in turn setting up the murder to be solved in the next episode. In the finale, the final three guests (the killer and the two remaining players) compete in a multi-part riddle and memory challenge based on elements from all of the previous murders. The first player to complete this challenge is directed to a final room to confront the killer, while the last player is sent elsewhere and subsequently eliminated. The killer confesses his or her identity to the last guest and congratulates them for winning the game
