◇ Rules

① General Principle

Participants must cooperate to identify the traitor lurking on the ship. If the real traitor is killed, the game ends. All survivors are freed. If an innocent person is killed, only the perpetrator is "punished" and dies. If the group reaches the final two, they are released.

② Regarding the Traitor

A traitor is chosen at random once a week. Letters are distributed to all participants; the one chosen as the traitor must kill another participant within one week or die themselves.

③ When a Murder Occurs

After a set period of investigation, the survivors discuss to find the culprit. A voting period follows to vote for the culprit.

④ If the Murder is Successfully Concealed

If the traitor who killed a participant manages to hide their identity for a set period, only the traitor survives. In exchange, all other participants who failed to see through the deception are punished.
