Most of my awareness of puzzles and puzzle games has come from a decade of haphazardly stumbling around the internet. There's a flavor/genre that I particularly enjoy, but I haven't had much luck finding more of them - or even nailing down to correct terms to find them. Lo and behold, I finally stumbled across this question, and it inspired me to ask you fine puzzlers for help.
I enjoy puzzles that are enigmatic - where you're presented with zero hints or guidance, and all progress and information is hard-won through deduction / trial and error. Here are a few great examples:
Unfortunately all I have are links to Newgrounds, which should immediately indicate how much I'm hurting for fresh specimens. The main problem I seem to be having is that the "Puzzle" category in any given source is very ambiguous - they lump in anything from bejeweled to jigsaws to quiz games, and after years of casual searching I'm tired of filtering through hundreds of pages with no success.
Is there a specific name for this kind of game? Are there any sites or sources that would help me find more? I'm completely in the dark here - any help or insight is much appreciated.
