Mystery Mansion (board game) Mystery Mansion (board game) Mystery Mansion is the name of a series of board games in which players search furniture and other objects inside a mansion to locate a hidden treasure or stash of money. The first version of the game was released by the Milton Bradley Company in 1984, the same year when Hasbro took over that company. Instead of a standard game board, the original "Mystery Mansion" features a modular board where players build the mansion by adding new rooms drawn at random. Hasbro then released an electronic talking version under its Parker Brothers brand in the 1990s.
