Puzzles...where?
The only puzzles I have ever found in skyrim, is those crypt circle doors, but even then the answer is on the key.
You haven't been doing much dungeon-diving, then. There are a variety of puzzles throughout the game, mostly in draugr or Dwemer ruins.
That being said, they're nowhere near as hard as the puzzles in the Tomb Raider series. I can always figure out Skyrim's puzzles if I think about what they're asking me to do. Some puzzles are harder than others, of course, but I've never had to cheat and look up the answer for any of Skyrim's puzzles so far, like I used to do regularly with Tomb Raider.
