Players explore a castle made up of tiles that are solid on three corners and pivot on the fourth corner, creating a 'trapdoor'. On your turn you can move as many spaces as you want until you voluntarily stop or fall into one of these trapdoors. The object of the game is to have each of your three knights collect a pair of family portraits that are located in the corner 'Portrait Galleries' and then make it to the middle of the board where the Treasury is located. The first player to get all three knights there, wins.The memory element comes into play as you try to remember which paths are the safest route to take as you collect your portraits. - BoardGameGeek
