2 mines left, and this is supposed to be No-guess.
However, it seems that there can be two answers to this -
(A) The top square of the top pair and the top square of the bottom pair, can both be mines.
(B) The bottom square of the top pair and the bottom square of the bottom pair, can both be mines.
But then this is not really guess free, is it ?
(Note - I did go with option (A), and it proved to be right. But my original question still stands).
What am I missing ?
Bang on !
I don't know how I missed that. But thanks for pointing that out !
I think you missed it because of the "highlight unsolved numbers" option, which greys out numbers that have all their mines even if the rest of the squares aren't all open. I recommend you turn that off.
I did that just now, and it certainly seems to help ! Thank you kind stranger !
