actually, take it back. heavy green use, but doable with no checkpoints needed.
Guessing = onlycheatingURself Green is good. Gordon Getgrnokeydok
I like this kind of easy -- it unraveled slowly, but no greens or special techniques required. (I refuse to use greens on an easy, and will guess only on an expert. For a long time, I skipped the experts because I felt that guessing was cheating, and that I just needed to learn more advanced techniques.)
Did it, no green, no guess. Some unique rectangles and virtual numbers. I'd call it a Medium.
janetb - you are right that you just need to learn - guessing isn't "cheating" but it's making things harder on yourself. track your "guess" with a forcing chain and then it's not really a guess anymore, and saves you time.
what exactly is a 'forcing chain'?
and a 'unique rectangle'?
Difficulty score 33. No green.
