Hardest Puzzle

[Dragan]

For the people who beat the whole game without any hints or clues from the youtube or google or whatever, what was your hardest puzzle to solve. While some puzzles were little bit more difficult than another I solved most of them in 15-30 mins but the Valve one took so much time I felt ultra retarded by the end and almost gave up. I though from the book that every valve that is horizontal is closed and vertical is open and spend forever looking for 4th cap only to find out it simply doesnt exist and its just a puzzle that looks so simple and me being stupid that I don't see what is wrong with my logic. It didn't even felt good once I solved it, just sad.

Wait hold on I just remembered which puzzle I was never going to get.

Having to walk around the corpse 3 times counter-clockwise with the lighter. Whoever got that, you've got my respect.

Cash register took me about 30 minutes, other than that no more than 5-10 on any other puzzle.

Definitely the TV, didn't think to do it like a combination lock so I was flipping the tv off and on and going to the next one. I had all the ideas, just sucked at the execution, then the "bug" of the dial not turning correctly. I'd pull my cursor to the right and come in from the right so it'd turn left, coming in from the left made it turn right, but sometimes it'd go opposite.
