This is guess-free, and 14 mines left, all under those uncovered squares.
Any thoughts on how to proceed ?
EDIT - never mind. Tried brute force with the hope that the path I choose would be the right one - and lost.
But there's always a next ~~time~~ mine, lol.
And it was indeed heartening to see the Minesweeper community in Lemmy is not dead.
The 3 4 3 section in the middle is where you want to start.
I think so too, but so have been unable to reason anything. Heading in brute-force is obviously the last resort for me, but was looking for something logical before I do that.
I believe the two squares immediately above and below the right 3 must be mines. Let me see if my reasoning makes sense: The 4 has five remaining squares around it, but three of those overlap with the 3 to its left. That 3 already has one mine marked, so those three squares that neighbor both it and the 4 can have at most two mines in them. That means the two squares that don't overlap must both have mines.
Your reasoning makes perfect sense, and now I wish I didn't brute-force it head-first. Thanks for pointing that out !
