It’s the room with the Walk Bridge. I’ve got the head in a box and placed the three stones in the glass slots under the walk. But I can’t either find the right arrangement of the stones or the right way to put the head into the machine. Any help?
A thought: The stone tiles only go in one way. You can pull them out a little ways, but then they go back in. I think this is meaningful if you know how to move them in and out.
The solution is in how far out the tiles are pulled. The head can be put anywhere on the “glass box with holes”. If you still can’t get it, check the next spoiler box.
total spoiler MOTaS:
Start all the tiles all the way back. Click twice on the left tile, once on the middle, and twice on the right. Put the head down.
