Can you figure out where the mines are in the below board? Blank squares indicate that it is unknown whether there is a mine in that space. Squares with numbers contain no mines (or you would have already lost).

+---+---+---+---+---+---+---+

|   |   |   |   |   | 3 |   |

One solution is as follows

if the columns are numbered from left to right as 1 to 7 and row are labeled as a,b,c,d,e,f,g from top to bottom then.

Then the mines are in the following blocks

a5,a7

b2,b3

c5

d2,d5,d7

f1,f3,f4,f7

g7

This was an interesting one.
