Rules at a glance

Original Libellud edition with clairvoyancy tokens. The rulebook adjusts play for two or three players; later editions can differ.

Your goal

Help every psychic identify their own suspect, location and object within seven hours, then collectively identify the culprit’s complete group.

The flow of play

  1. The silent ghost gives vision cards to each psychic for their current stage of the investigation

  2. Psychics discuss, place guesses and advance only when the ghost confirms a correct card

  3. If everyone finishes within seven hours, use the final shared vision and vote for the culprit’s group

A quick introduction to the base game. Use your edition’s rulebook for full setup, card effects and exceptions.
