Done. 1 guess.
I quit for now.
Done, with greens and a guess.
back to it
g/ng - one coloring chain
One choke point. Picked one of five possibilities in least constrained cell. Turned out to be a lucky guess. On a bad day it could have been a long journey through four unlucky guesses.
Found something which I'll call an "either way virtual." Either of two possible positions for a number in one block results in that number in just one column in another block.
Did it, no green, no guess. The "either way virtual" was the key. It pretty much ran out as an easy after that. Love when that happens.
done with greens..and 2 bad guesses... "sigh"
would love to know what an either way virtual is and how to spot one
I've filled all the greens in, now how do I solve it without a guess. This is where I get stumped on the experts.
