You have managed to find the entrance to the ancient castle dungeon in Rock Slide. It turned out that a whole chain of corridors was hidden under the building. Each of them ends with a locked door with complex and intricate locking mechanisms. It is a set of stones of regular cubic shape and red buttons. Each cube must be moved onto a button for the door to open. Carefully inspect the mechanism, it is very important to move the stones in the correct sequence so that the already moved cube does not interfere with another one that needs to be moved in Rock Slide.
