Mysterium

Mysterium is a cooperative deduction board game that turns one player into a silent ghost guiding a team of psychics to solve a mysterious murder.

Each game, the ghost can’t speak and instead uses surreal illustrated vision cards to hint at the true suspect, location, and object behind the crime. The psychics discuss, debate, and interpret these dreamlike images, advancing along their own paths of suspects and places as the in-game clock ticks down. Only if everyone correctly identifies their personal sequence can the group combine their insights for a final attempt to crack the case. This refreshed edition of Mysterium preserves the beloved gameplay while offering an updated presentation for a new generation of players, supporting 3–7 investigators, ages 10 and up, in sessions of about 45 minutes. Available now at Boarding School Games—bring a hauntingly good whodunit to your next game night.
