I feel it was a bit unfair, because...hope I'm not hinting here...the answer to this is NOT easy to find. I could add more but I would be giving hints.
I've been green on week 4 since it came out, but I will add one comment. I don't know if anyone agrees with me or not. Week 4 "Secret Room" password was unfair. I can see why people are struggling with it.
I know, it's all part of the game.
