A question of minesweeper

Question

Here is where I am. Is there a unique solution somehow?

I find that a lot of minesweeper games/apps make the game more "difficult" by forcing random guesses. Those are rather annoying as I think that these should be solvable with pure logic, zero guess work. — dcfyj, Jul 12 '18 at 17:25
@dcfyj I am thinking the same way. It is meant to be a pure logic game, not a probabilistic one. — Ruifeng Dong, Jul 13 '18 at 17:47

With the information given,

there is no unique solution.
Both of the below are valid sets of mines (and there are two more, if you want to find them):

There may yet be a unique solution depending on how many mines there are; OP hasn't specified that yet. – F1Krazy Jul 12 '18 at 17:48
@F1Krazy True. There's only the one solution with 4 mines. It's not unique with any more than that. But that information wasn't given, so I haven't included it. – Jul 12 '18 at 18:07

Mnemonic has already answered your question; unfortunately there is no unique solution and you have to guess.

What I would like to point out is that your best option probability-wise is to click on one of the 10 edge squares not adjacent or diagonal to a number and work from there. The probability of a mine in those squares is between 1/10 and 1/5 whereas for the others it's between 1/3 and 2/3.

How did you know the number of bombs? – kaine Jul 12 '18 at 17:47

I counted 93 bombs found out of the 99 bombs on expert mode meaning 6 left. – SadioFirmiMo Jul 12 '18 at 17:56

these are the four possible mine position combinations

there are no "safe" squares
