Wow! That was one of the hardest puzzles I've done in a long times, Greens & guesses.

guess i am not an expert today...

easiest Ex in a very long time...about a 3 or high 2...all elimiations...??

you have got to be high...

Today's was the harded Expert one I've encountered! Ugh.

i wouldn't think being high would actually help you solve the puzzle...

rats, almost thought my forcing chain was leading to the solution, instead of a simple negation.

curses, foiled again. well, slow and steady will do it eventually, but it is tedious. i'm with the "this is fracking hard" crowd.

three contradictions are a charm

at least they better be. if i screwed that up i will kill myself.

oh geesh. forgot to contemplate possibility that i didn't screw up but yet another forcing chain could be required elsewhere.

argh, not even the sop of a contradiction in that one!

tooth... nail...

that should be worth 10. night.

wait, no dr who rating???? sigh.

Hurshy, just for you, difficulty score 92.

go

Done. Finally. ng. but that took a ridiculously long time with many restarts.

Yeah, this one is troubling.
