Ok SPOILERS AHEAD
For the numbers what I did(because I am a visual person) I drew the floor plan on paper and cut it out. You then fold it into a box. And that is how you see what number goes in what box. Or if you can visualize it in your head w/o having to draw it out and fold into a box shape, do that. So, by looking at the one door that has a knob, you should be able to tell the orientation of the doors and what number goes in what box. The worm puzzle. Is an optical illusion of types. If you look closely one of the snakes curls OVER itself, and the other one curls UNDER itself. You then put each of the snakes in the corresponding pile. Hope this helps. If you want more specific spoils let me know.
