I have arrived at this board and I'm kinda stuck. Is there any way to continue without guessing?

    $\begingroup$ As @RobPratt and @JLee noted, you need 4 more mines to finish this game, but the counter reads 003. I count a total of 95 flags, and the typical Expert game has 99 mines, which suggests to me that the counter is wrong; it should say 004 instead. Maybe your Minesweeper app has a rendering bug? $\endgroup$

    $\begingroup$ Because of the incorrect counter I spent a while searching for an error in the solved parts, thinking this could be a trick question with answer "first remove this flag which was a mistake". But I agree, the counter must be wrong. $\endgroup$

    $\begingroup$ @Rufflewind: Rendering bugs can never give this result. It's probably due to a race condition, which is common in sloppy software. $\endgroup$

Because the left 5 needs two more mines, the remaining mine for the adjacent 3 must be in the top right cell.

Also, that same 3 uses up all three mines indicated by the counter, and that leaves nothing to cover the bottom two remaining cells, so you must have an error elsewhere.


As RobPratt pointed out, you can mark the flag highlighted in green below:

However, you will have to guess, because there are 4 boards (thx for the correction, aschepler) that satisfy the conditions that you have:

    $\begingroup$ 4 boards. But it's still the case that each of the remaining six unknown cells has probability 1/2 of containing a mine. $\endgroup$

  • $\begingroup$ From your two valid boards, the flag above or below the leftmost 5 can change independently of the other three flags. $\endgroup$

  • $\begingroup$ Yes, my mistake (but on an originally covered square). I see you've already posted a correct image. $\endgroup$

Mines in the top middle (above the 3), along with immediately below that same 3, and the bottom left seem to validate all constraints, and use only 3 mines as indicated as remaining on the counter.

    $\begingroup$ That handles the top 3 but doesn't leave any mines for the bottom two 3s. $\endgroup$
