the principle is simple: a protective ring of magic kingdom was stolen by one of ten characters. Children should move around the castle (a ghost has parallel movements that can block). Just follow the instructions of the characters through electronic safe: you press an animal to identify the location and then chooses an action. It is not easy, there is also an element of luck and we must remember what we have already done. Some doors are unlocked and you can dig some chests.
One part is in limited time allowing play fifteen minutes while putting some stress (time scrolls when you press the buttons, so you can have time to think, and sometimes on the end, better is to do nothing than to choose an action).
Little has been at Christmas and he demands more parts per day. I'm really happy with this gift and I think the offer to other children on occasion. Really, we are rarely disappointed by Ravensburger games, what quality!
