Mansions of Madness is a board game released in 2011 for 2–5 players, 120–180 minutes per game, and ages 13 and up. It was designed by Corey Konieczka and its main mechanics are Variable Player Powers, Hand Management, and Area Movement.
Description from the publisher: Horrific monsters and spectral presences lurk in manors, crypts, schools, monasteries, and derelict buildings near Arkham, Massachusetts. Some spin dark conspiracies while others wait for hapless victims to devour or drive insane. It’s up to a handful of brave investigators to explore these cursed places and uncover the truth about the living nightmares within. Designed by Corey Konieczka, Mansions of Madness is a macabre game of horror, insanity, and mystery for two to five players. Each game takes place within a pre-designed story that provides players with a unique map and several combinations of plot threads. These threads affect the monsters that investigators may encounter, the clues they need to find, and which climactic story ending they will ultimately experience. One player takes on the role of the keeper, controlling the monsters and other malicious powers within the story. The other players take on the roles of investigators, searching for answers while struggling to survive with their minds intact. Do you dare enter the Mansions of Madness?
Mansions of Madness supports 2–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Mansions of Madness is 120–180 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Mansions of Madness for ages 13 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
