Before you can even enter the building you discover the Hand has sabotaged the dish on the roof, making the door too hot to touch. Simply use the Alchemist Magnet to turn the gold dish to lead to stop the sunray from being reflected.
At the Towers of Anoi, you have a complex puzzle with a simple goal: move all of the pieces from the right statue to the left statue. The only restriction is that smaller pieces cannot be placed on top of larger ones. Your first goal is to move every piece to the first (leftmost) tower. There are many ways to solve the puzzle but if you really don't want to mess with the pieces too much follow this order from the very beginning (ordered left to right):
If you mess up don't stress too much - just keep moving the pieces around. Once you manage to place the smallest piece (yellow) on the correct statue, you're pretty much home free.Now that you have the most valuable item in the land once again, the next goal is to move every piece onto the middle statue. Follow this order if you need guidance moving them from the left statue:
The second statue rewards you with the missing gear from the control room. Head there with your trusty stick and use it to wedge the gear into place. When the Hand shows up for the final showdown, leap at the Kyrandia console that you just repaired in order to dodge. Next, keep clicking the Hand to keep him busy while Marko works to free himself. Once Marko crawls behind the Hand, give it a final push to send it flying into the gears to be ripped into shreds.
With the Hand's evil plot foiled, Kyrandia is saved once again!
