Mystery Mansion (1984)

Mystery Mansion is a unique search game that challenges you to build a Victorian Mansion, room by room, as you search these rooms for hidden treasure. Build the mansion by adding new rooms onto existing rooms with the roll of a special die. Every room contains many objects which are all possible hiding places for clues to the whereabouts of the Real Treasure. Search cards allow you to look behind, under and inside these objects for clues. Try to add rooms that you suspect contain objects that match Search cards in your hand. If you have a Search card that matches an object in the same room as your pawn, play it and draw a Clue card. The clue might be a Treasure Chest, a Key to a chest, a Secret Passage or just Cobwebs and Dust. If you own a key that matches a chest, haul the chest out of the mansion to unlock it. Once it's outside, the big moment comes as you open the lid. Will it be filled with gold and jewels or cobwebs and dust?
