The Singing Stairs
When you enter the alcove and climb the stairs, each step will make a sound. At the top of the staircase is a panel of levers marked with the letters A through G and have sounds corresponding with each step. The object is to pull the levers in the order that creates the same sounds as each step from the bottom up. The correct order is "B," "A," "D," "C," "A," "D," "E," "E." When played correctly, a compartment will open to reveal a key. Put the key into your inventory.
The 13 Ghosts
At the desktop computer, type in the password, press the "Enter" button and select the "I am" button; this starts a timed ghost hunt. Hurry to find and click on all 13 ghosts. There are four ghosts hidden in the Great Hall, three in the lower hall, three in the upper hall, one at the top of the singing stairs and two in the conservatory.
Hands of the Dragon
The Dragon protects a hidden passageway. The dragon has six movable hands -- three on each side. To defeat the dragon you need to arrange the hands in a certain way. The clue is the coat of arms on the door. Torn the hands to point the fingers in the correct direction. Zig-zag down starting at the top left. The settings of the hands are: right, up, down, left, down, right. The passage will open, but it is too dark to enter.
The Gargoyle Statue
As the game progresses you learn that the gargoyle protects a secret passage. Find the portrait that has a gargoyle in the background; the clue is on the crest, but it is missing. Go see Nigel; he will ask you to perform a task in exchange for the crest. Once you receive the crest you will have the clue you need to open the passage. Go to the gargoyle and turn it right, right, left, right, left, left, right and then left. The passage will open.
