Mysterium

Mysterium is a cooperative deduction game for 2–7 players, designed by Oleksandr Nevskiy and Oleg Sidorenko and published by Libellud in 2015. Set in a creaky old manor, one player takes on the silent role of a murdered ghost, while everyone else plays as psychic investigators trying to identify the killer, the location of the crime, and the murder weapon. The catch: the ghost can only communicate through beautifully illustrated dream cards — surreal, abstract visions that must be interpreted by the psychics to point them toward the right suspect, place, and object. With only seven rounds to crack the case, the pressure is constant and the atmosphere delightfully eerie.

What makes Mysterium sing is the interplay between the ghost and the psychics. The ghost player studies each investigator’s assigned cards and must choose from their hand the dream image that feels most like a clue — a hopeful cloud formation, a chaotic kitchen scene, a moonlit graveyard — without being able to say a word. The psychics then debate, bicker, and speculate about what the ghost was trying to say, making it as much a game about communication and empathy as deduction. The tension is shared across the table in a way that few cooperative games manage.

Often described as a marriage of Dixit and Clue, Mysterium is a staple gateway game that works brilliantly for both hobby gamers and complete newcomers. Its lavish artwork — which won the 2015 BGG Golden Geek Award for Best Artwork — gives every session a genuinely atmospheric feel, and the wide range of vision cards ensures the interpretive puzzle stays fresh across many plays.
