Players play the role of an adventurer and explore the mansion room by room. They must avoid the scary creatures that live inside to discover its secrets.
The game is a memory card game containing 36 Castle Cards that are divided into monsters, gates, candles, potions, cards and a portcullis. Players shuffle the cards and build a 6x6 grid by looking at the cards before placing them face down with the first card in the middle of the table. As other cards are placed must touch the edge of another card. However, the doors are first placed face up and, as far as possible, should not be placed next to each other.
The last player to add a card chooses the door he wants to start on and the remaining doors are turned face down. Players move around the board moving to the next card face down in a straight line (up, down, left or right). Face-up cards or spaces can be skipped.
