A circus with dark secrets awaits you in Mysterium Park! The park's former director disappeared several years ago... An investigation turned up nothing. Since that night, strange things have been happening in the circus... Mysterium Park is a standalone, cooperative, and simplified version of the popular board game Mysterium: players win or lose together. Your goal is to uncover the circumstances of the ghost's death. At the start of the game, players first choose a role: Ghost or Clairvoyant. The Ghost (player 1) must guide the Clairvoyants through the investigation. He provides clues in the form of illustrated cards called Vision Cards. This is the only way the Ghost can communicate with the Clairvoyants. Each Clairvoyant (all other players) must eliminate a suspect and a location, and they help each other interpret the Vision Cards the Ghost hands them. To win Mysterium Park, the Clairvoyants must figure out who committed the murder and where the crime took place during Round 3. The Psychics must first eliminate suspects (Round 1) and then locations (Round 2). If they succeed in doing so in the first six turns, they advance to Round 3. If not, everyone loses the game. If the Psychics win, the Ghost also wins. If not, all players lose.
